Machine, especially a padding machine, for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, including a main support framework of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine, a cabin for housing the driver of the machine, such a cabin is in the form of a cabin movable with respect to said main support frame. Said cabin for housing the driver of the machine can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

A screening arrangement including two side walls, each having an inward facing side and an outward facing side, and a screen holder arrangement extending between the inward facing sides of the side walls for use in connecting a first and a second screening element. The screen holder arrangement includes a first screen connector and a second screen connector. The first screen connector includes a pivotable element arranged to pivot about an axis that is parallel with a longitudinal extension of the first screen connector. The pivotable element includes a connection portion arranged to hold one end of the first screening element. The pivotable element is arranged to pivot between a first position and a second position, where the pivotable element is arranged such that when it is in the second position and a screen is connected to the pivotable element, particles larger than a predetermined size are prevented from passing between the first and second screen connectors.

A vibratory drive system, suitable for a material screening apparatus, includes rotatable drive shafts each having a centre of mass offset from its rotational axis. A respective drive mechanism is coupled to each drive shaft and is controlled by a controller. The controller adjusts the relative rotational speed of the drive shafts to adjust the relative angular position of the respective centre of mass of the drive shafts. This adjustment allows the vibratory characteristics of the drive system to be changed without having to halt the drive system.

A material processing unit includes a main frame and a pivot assembly pivotally mounted to the frame. The pivot assembly is movable between a first pivot position, where a portion of the pivot assembly extends below the main frame, to a second pivot position, where the pivot assembly is generally above the main frame. The pivot assembly includes a mount platform that is below the main frame when the pivot assembly is in the first pivot position. The pivot assembly includes a slewing bearing mounted on the mount platform. The pivot assembly also includes a carrier mechanism that is rotatably mounted to the slewing bearing. The carrier mechanism is configured to be rotated generally parallel to the mount platform via the slewing bearing. The material processing unit includes a discharge conveyor that is pivotally mounted to the carrier mechanism.

This disclosure relates to a system and device for cleaning impurities, garbage, rocks and etc. from sand. In one embodiment, a sand cleaning device includes a spinning brush head that includes one or more flaps that push sand through a screen while retaining impurities, garbage, and rocks within a receptacle. The system includes a remote power unit for powering the sand cleaning device.

The invention relates to a rock processing machine (10) having a feed hopper (40) and a process unit (20) downstream thereof, wherein a conveying device, in particular a hopper discharge belt (12), is assigned to the feed hopper (40), wherein the feed hopper (40) has a hopper side wall (42), and wherein a side-wall heightening (44) is assigned to the hopper side wall (42), which side wall heightening can be swiveled between a folded-down working position and a folded transport position. In such a rock processing machine, the requirements of occupational safety are effectively taken into account in a simple manner if provision is made that an operating unit (50) having a lever (51) for swiveling the side-wall heightening (44) is assigned to the side-wall heightening (44), wherein a transmission element (52) is used to couple the lever (51) to the side-wall heightening (44), and that the side-wall heightening (44) is secured in the folded-down working position using a movable locking element (60).

A screen drive for a mobile material processing screen which can be at a travel width without having to fold or disable the screen drive. The screen drive system includes a drive motor, which is tucked at least partially under the vibrating screen; a sheave, having a double row ball bearing being supported by a shaft; a belt, coupling sheave and drive motor; a drive shaft coupled to a first universal joint, and a second universal joint, which is coupled to an opposing end of the drive shaft and to sheave.

A system for processing usable crop intermixed with debris and having a frame with a conveying system thereon. The conveying system has a first debris separating assembly with a first subframe having a plurality of cooperating rollers that are configured to cause separation of debris from the usable crop. A second debris separating assembly, different than the first debris separating assembly, has a second subframe with a plurality of cooperating rollers thereon that are configured to cause separation of debris from the usable crop. The frame and first and second debris separating assemblies are configured as overall like modules so that the first and second debris separating assemblies can be separately operatively connected, one in place of the other, on the frame.

A mobile aggregate processing plant for screening aggregate material comprising a mobile chassis, a vibrating screening unit mounted on the mobile chassis and able to provide at least one aggregate discharge stream therethrough, and an underscreen conveyor located wholly or substantially beneath the vibrating screening unit to wholly or substantially receive said at least one aggregate discharge stream, wherein the underscreen conveyor is driveable in an uphill direction so as to be able to discharge the aggregate discharge stream at a height higher than receiving the aggregate discharge stream, relative to the mobile chassis.
