The invention relates to a heavy machine-operated sieve screen bucket. A plurality of screening plates () are spaced from each other and establish a screening surface (), which is provided with screening slots and on top of which the material to be screened can be placed. There are rotatable shafts () below the screening surface (). The shafts () are provided with blades (), which are projecting from the shafts and which extend through the screening slots to above the screening surface (). The blades () taper in a wedge-like manner towards their rounded tips. Side edges of the blades () are substantially straight and the angle between the same is in the range of 20-28&#xb0;.

Heavy machine-operated sieve screen bucket

A method and a device for screening aggregates and/or soils with a screening deck, where each point of the screening deck revolves continuously in the same rotating direction along a circular path. This movement is effected by the fastening frame of the screening deck being bearing-mounted upon at least two eccentric shafts, where each eccentric shaft is in turn bearing-mounted on a device body with bearings, through the midpoints of which extends a rotation axis of the eccentric shaft. Additionally, a throw axis spaced from the rotation axis of the eccentric shaft extends through the midpoints of bearings present between each eccentric shaft and the fastening frame, so that when the device is in operation, the throw axis revolves around the rotation axis along a circular path continuously in the same direction. All mass forces of movable structural components have been balanced with respect to rotation axes.

The invention relates to a method and apparatus for returning the oil drained from a working pressure space of a hydraulic motor into a motor casing to an oil line, which is connected to the motor and which is in communication via a divider with intra-motor flow channels which are in communication with the working pressure spaces. The oil seeping into the casing is conveyed by means of pressure variations internal of the hydraulic motor, pulsating consistently with rotating motion, into the oil line presently at a lower pressure and connected to the motor by way of said divider. Therefor, the casing space is connected by a return conduit through a one-way valve to at least one flow channel, which lies between the divider of the motor and the working pressure space of the motor.

The invention relates to a leakage oil return apparatus for a hydraulic motor. The apparatus is used for returning the oil leaked from the working pressure space of a motor ( ) into a motor casing ( ) from the casing ( ) back to a return line ( ) of the motor. Consequently, the return pump ( ) driven by a shaft ( ) of the hydraulic motor ( ) has its suction side ( ) connected with said casing ( ) and its delivery side ( ) conencted by way of non-return valves ( ) with pressure and return lines ( ) of the motor ( ) in such a way that flow communication is established always with the line having a lower pressure. It is preferred that the return pump ( ) have its delivery side ( ) connected by way of a pressure proportional valve ( ) with said casing ( ). The pressure proportional valve ( ) is adapted to receive its control from the pressure ratio between a casing pressure and a pressure in the delivery side ( ) of the return pump ( ) in such a way that, as the casing pressure goes down below a given pressure limit or approaches the pressure of 0 bar, the pressure proportional valve ( ) switches the return pump's ( ) volume flow to free circulation i.e. back to the casing ( ).

A method and apparatus for blending and transferring earth material at a blending site. The apparatus has a sinking shank mounted on the end of a boom of a working machine. Two cutter drums are mounted in spaced relation on the end of the shank for rotation about a horizontal axis. The working machine is advanced toward the blending site. The cutter drums are sunk into the earth material at the blending site and rotated to effect blending. The cutter drums are drawn toward the working machine to further effect blending and transfer a portion of the blended earth material to an accumulation of blended earth material over which the working machine advances.

The invention relates to a method and an apparatus for accelerated biodegradation of organic matter. The apparatus includes an enclosure for receiving a stack of organic matter and at least one fan connected to a series of aeration ducts for directing a gas containing oxygen through the stack. After passing through the stack the gas is collected and passed through a scrubber and a heat exchanger that cools the gas. A portion of the gas is exchanged with a portion of a replacement gas and then the gas is recirculated through the stack in a substantially closed loop system. The temperature, oxygen content, and flow rate of the gas are controlled to provide a sustained accelerated rate of biodegradation in the stack. In addition, the stack is periodically agitated.

Double stage drumshaped composting device

The invention relates to a bucket crusher to be mounted in place of the bucket of an excavator or a bucket loader. Horizontal crushing shafts (12) provided with crushing tools are superimposed at a small distance from each other and adapted to be rotated in the same rotating direction. A pivoting axle (4) for a pivotably journalled compression and feeding plate (1) is located in the top section of the bucket. The plate (1) can be turned for pressing the material to be crushed against the crushing shafts, whose rotating direction is selected in such a manner that the crushing tools within said bucket travel towards said pivoting axle (4).

Bucket crusher

Soil materials are screened and crushed simultaneously in a bucket of an excavating machine having its back wall replaced by rotatable crushing and screening elements. The crushed and screened materials fall down through the back wall and the non-crushable materials with size exceeding the size of screen openings remain in the bucket for dumping in the pile of a coarse pieces.
