A hydraulically-foldable agricultural machine frame includes a hydraulic cylinder assembly that connects and pivots two lateral parts of the hydraulically-foldable agricultural machine frame relative to one another, wherein unrestricted pivoting or folding of the lateral parts is prevented by movement of the hydraulic cylinder assembly only being guided or delimited laterally.

Agricultural machine frame

The invention relates to a hose connector system () for use in an agricultural spreader machine (), which system is characterized by rapid and secure assembly, and therefore economical production and high modularity.

An agricultural seed drill with a seed sensor, generally of the type having a plurality of row units comprising a separation device. The separation device is provided with two or more separate outlet openings for separated seeds, and wherein each outlet opening is associated with a guide channel and a furrow opener, for depositing seed into a ground furrow. Further, a detector is arranged between the outlet opening and the furrow opener, to detect the discharge of a separated seed element through the outlet opening into the furrow opener and to convert it into a signal.

Viewed in the direction of travel, fertilizer coulters and swivel-mounted seed coulters () are arranged at coulter arms () on the frame () of a pneumatic precision seed drill. Between them there is a working device designed as a roller (), which is designed for the re-compaction of the soil thrown up by the fertilizer coulter (), the pre-compaction of soil between the working device () and seed coulter (), and as a depth guidance roller for the precision seed drill.

A multiple singling device is mounted on a row unit of an agricultural single-seed drilling machine and has a split housing with a multifunctional center piece.

Multiple singling device

A pneumatic precision seed drill has a multiplicity of seeding heartsfor holding pivoting separating devicesexposed to a pressure difference between their inner spaceand their exterior space. A multiplicity of holes-intended for the accumulation of seeds is arranged in the device. The separating deviceis formed by a pair of separating platesconnected to one another at their outer edgethat are arranged offset in a tangential direction to one another to produce a spread seed row and are assigned to separate outletsfor the discharge of the seed from the seeding heartin the direction of the sowing coulter.

A double disc coulterhas two disc coultersangled to each other to form a V shape that are rotatable on hollow axle stubsby means of bearing units. One hollow axle stubis arranged with a flange facefacing the coulter barat an angle to the vertical plane of the rotation axis of the hollow axle stubs. At the same time, the hollow axle stubdetermines the angular position of the planethat intersects in the rotation axisand in an axisvertical to the flange faceof the coulter bar

Double disc coulter

In each case at least one double disc coulterand one depth control wheelareas arranged on the frameof a pneumatic precision seed drill. Seen from the direction of travel, this depth control wheelis located between the two disc coulters, whereby the two disc coultersand the depth control wheelrotate in the same direction.

A compact bearing unit () for a double disc coulter () with ball bearing () with an inner ring (), outer ring () with flange facing and a protective cap () has a multi-stage sealing system. A first seal () is provided between the inner ringand an internal ring race () of the outer ring (). At least one additional seal () is arranged between the protective cap () and a ring race () of the outer ring (), whereby said seal does not make any additional installation space necessary in the axial direction of the bearing unit ().

A metering system is proposed for an agricultural distributor for dispensing granular or granulated material with which a vertical cell wheel arrangement in combination with an adjustable cell wheel floor achieves great variability of the adjustable metering volumes with reduced drive energy requirement.

Dispensing system for an agricultural spreader machine

A combination of a harvesting machine, a crop picking head, and a vehicle to support the crop picking head. The vehicle features a mount and at least one wheel extending down from the mount that supports the crop picking head and alleviates the weight on the front wheels of the self-propelled harvesting machine when driving on the road. The vehicle is attached to the crop picking head when driving on the road and detached from the crop picking head when harvesting a field. The crop picking head includes a support frame which supports the harvesting equipment. In the preferred design, the mount is connected such that the support forces of the vehicle pass directly to the support frame rather than load more fragile components of the crop picking head.
