An implement for spreading granular material, such as fertilizer, wherein the flow of fertilizer from the hopper is controlled by the position of a metering slide under an outlet opening of the hopper. The metering slide has an indented asymmetric edge which cooperates with the outlet opening to control of the flow of fertilizer onto an underlying spreader. The metering slide is moved into its position under the outlet opening by the pivotal movement of a sector-shaped support in hinged connection with the metering slide. The metering slide is urged against the hopper and the sector shaped support by a spring. The flow of material from a plurality of outlet openings is selectively controlled either individually or in unison. Also, the implement can be tilted.

A device for maintaining dairy animals and surface areas where they may be confined in a clean condition, and providing a station for feeding, milking and elimination of wastes which is movable as a unit. The station has a waste disposal at the rear and a feeder forward. An electronic system causes an animal to enter the station prior to waste elimination. A sensor determines the presence of animal waste. An electronic system that remotely guides the animal, comprises a radio transmitter at the station, a radio receiver mounted on the animal to guide the animal by shock or sounds to the station and/or sounds produced at the station attract the animal. A sensor on the animal's tail that signals the onset of elimination or presence of waste, may be coupled to the station's electronic system, or to a speaker near the animal's ear for producing unpleasant sounds to discourage elimination outside the station. Electronic systems are used to reward the animal after its elimination in the station. The station comprises devices to clean the animal's udders and substantially simultaneously to flush the animal's droppings from a grating into a waste disposal area, and to milk the animals subsequent to cleaning. After the animal's elimination and other processes are complete, the station is opened at its forward end and the animal is induced to leave.

Arrangement for keeping dairy animals clean

A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution member with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor. The mechanical transmission includes a horizontal shaft connected to two vertical shafts for rotating the distribution members via bevel gears and is contained in a hollow tube with gear boxes on either end which maintain the axes and levels of the vertical shafts and distribution members in fixed relative positions. The tube and gear boxes are part of the framework connected rigidly to the delivery parts which maintains them and the distribution members in fixed relative positions. The hydraulic motor is connected directly to the horizontal shaft and mounted on one of the gear boxes.

Spreader

A spreader for spreading granular and/or powdery materials having a hopper and rotary distribution members with ejection blades on plates located below the hopper. The areas covered by the two distribution members can be adjusted so that they substantially coincide with one another. In some embodiments, the orientation of the ejection blades on the plates can be adjusted. Material flows to the distribution members through feeding means that include outlet openings and ports that can be in register with the openings. Also, displacers or closing members for affecting this flow can be positioned near the outlets at the lower portion of the hopper. A transmission, including change speed gears, can be connected through endless flexible members, i.e., ropes or belts to the shafts mounting the distribution members.

Spreader for spreading granular and/or powdery material

A device for spreading granular and/or powdery material comprising a hopper for material to be supported and at least two distributing members rotated in opposite directions about vertical rotary axes, material feeding means provided between the hopper and distributing members for feeding material from the hopper to the distributing members so that each of the two distributing members receives the material eccentrically with respect to its rotary axis; the distributing members having such shape and being drivable in a manner, and the feeding means being constructed and disposed whereby in operation material is supplied to the distributing members so that each spreads material across a sector which substantially coincides with the sector across which the other distributing member spreads material. With such a device the material is advantageously spread uniformly and different materials may be spread in the same manner without the need for readjusting various members of the device.

A shear pin coupling between two members has shear pins accommodated in a holder which is releasably mounted on a coupling member. The pins extend through holes in a supporting flange ring which is a component of the member. Resilient packing is positioned between the ring and the holder to prevent penetration of dirt to the pins. The resilience of the packing allows the holder to be tilted outwardly out of contact with an abutment surface of the member to allow removal of the holder.

Shear pin coupling

A mowing machine comprises a main frame (6) made up of driving units (36) and intermediate pieces (35) which are mounted alternately on a tie member (42). The tie member (42) is placed under tension, so pressing the driving units (36) and the intermediate pieces (35) together to make the main frame (6) substantially rigid. The tie member (42) is positioned substantially centrally of the driving units (36) and the intermediate pieces (35) so as to provide even loading of their mating faces. The driving units (36) have cutting units (8) with flexible hoods. The cutting units are driven by a drive shaft (41) through bevel gearing (46, 47). The direction of rotation of each cutting unit (8) can be altered by removing the gear (46) and replacing it to the other way round.

A soil cultivating implement comprising a row of power-drivable, soil working members supported by a hollow frame extending substantially horizontally perpendicular to the implement's intended direct of operative travel to provide selectively upwardly or downwardly directed forces upon that row via the hollow frame. A supporting ground roller is connected behind the row, its rotary axis being contained in an imaginary vertical plane. A mobile implement provides mass to exert a downward force on the cultivating implement at a coupling point which, in turn, is translated into an upward force on the frame's forward aspect by way of arms and strong pivots, such arms being turnable about the ground roller's rotary axis. The upwardly directed force assists soil-working members automatically to elevate as needed for riding over rocks or other buried obstacles without significant damage. In alternative embodiments, the mass's point of application is adjustable to a location in advance of the imaginary vertical plane whereby the force acting on the frame and soil working members is directed downwardly. This helps to work hard, heavy soils because it facilitates initial soil penetration by the working members and tends to prevent them from riding upwardly from the soil. In another embodiment, the mass comprises weights that are adjustably angularly displaceable around the ground roller's rotary axis to locations spaced at different distances from that axis and either behind or in front of such vertical plane.

The invention relates to a machine for working grass, hay or other crops on the field, provided with two rake members which are drivable about upwardly directed axes of rotation. During operation, the distance between the rake members can be changed by controls at the seat of the tractor on which the machine is mounted to adapt the machine to various circumstances. The machine is provided with swath forming crop guide members, the relative positions of which are automatically adapted to remain about the same irrespective of the distance between the rake members.

A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution members (3, 4) with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor.

An implement for milking an animal, such as a cow, that comprises a milking parlor where the animal can be positioned so that a robot arm which carries teat cups for application to the animal's teats can be positioned between the animal's front and rear legs. The robot arm is linked to a padded sensor that contacts the animal's hindquarters such that the robot arm maintains a relatively stable position between the animal's legs upon the animal's forward or rearward movement. The end of the robot arm can be located precisely relatively to the teats by an ultrasonic sensor. The implement provides for individual application of each teat cup to a teat and, once the teat cup is attached to the teat, the teat cup to be released from the robot arm so that a flexible connecting member provides the link between the rotor arm and the teat cup during milking. Upon completion of the milking, the flexible connecting member is used to pull the teat cup to the robot arm and seat it thereon.

A spreader has a hopper the lower region of which comprises a wall portion which coincides in part with a sphere and contains outlet ports for material to pass at an inclined angle from the hopper to a rotating distribution member. The free aperture of each port is adjustable by a dosing slide. These dosing slides are controlled by an adjusting mechanism capable of displacing either one of the dosing slides without displacing the other.

A cutting unit for a mowing machine which is driven by means of beveled gears contained in a drive housing. The cutting unit, which includes a rotatable disc mounting pivotal cutting blades is resiliently attached to the units' upwardly extending drive shaft emerging from the drive housing where power is transferred thereto from the mowing machine's generally horizontal drive shaft.

A mechanism that automatically attaches teat cups to a cow's teats including four telescopically extensible members which each carry a teat cup via a teat cup support which resiliently supports its corresponding teat cup in an upright position. Each extensible member has its own stepper motor to raise and lower the corresponding teat cup and a further stepper motor to move the extensible member horizontally within limits. An ultra-sonic radiation member is carried on a platform between the teat cups as seen in plan which emits a horizontal ultra-sonic beam that is reflected and focused upwardly and caused by movement of the reflector systematically to scan the cow's udder and to locate the teats by their comparatively shorter distances from the reflector. The disposition of the teats is thus sensed by a sensor unit which controls a stepper motors and causes the extensible members independently to raise the teat cups to be received by and attached to corresponding teats for the milking operation.
