Disclosed is an assembly for a dosing system of a spreader machine for distributing a granular material or the like, which comprises first and second members provided with first and second openings, respectively, and an actuator connected to at least one of the first and second members and configured to provide a driving force between the first and second members, thereby, adjusting an opening size of a dosing opening provided by an overlapping area between the first and second openings, wherein the relative movement is conducted by linear movement of at least one of the first and second members.

Disclosed is an assembly for a dosing system of a spreader machine for distributing a granular material or the like, which comprises first and second members provided with first and second openings, respectively, and an actuator connected to at least one of the first and second members and configured to provide a driving force between the first and second members, thereby, adjusting an opening size of a dosing opening provided by an overlapping area between the first and second openings. The first and second members are moveable by relative movement into a first position providing the dosing opening with a first opening size and a second position, different from the first position, providing the dosing opening with a second opening size different from the first opening size, wherein a center portion of the dosing opening is locally fixed when the members are moved between the first and second positions.

In one embodiment, the present disclosure includes an automated delivery system apparatus comprising a mechanical guide, a movable unit coupled to the guide on a first surface, and an engaging unit configured to couple to a second surface separated from the first surface by a thickness. The engaging unit is configured to engage an item on the second surface. A magnetic binding force between the movable unit and engaging unit moves the engaging unit along a path corresponding to a path of the movable unit. The engaging unit moves an item along a least a portion of the path.

In one embodiment, the present disclosure includes a granule dispenser comprising a container for holding granulated components, a cap coupled to a bottom of said container, and a stopper. The stopper may be spring loaded against the ridge of said cap. An interface between the stopper and the cap comprises a plurality of protrusions and a plurality of sawtooth forms, wherein the protrusions mate to a base portion between the sawtooth forms in a first position to form a seal between the cap and the stopper, and wherein, when the stopper is rotated, the protrusions engage a sloped portion of the sawtooth forms to create a plurality of openings between the cap and the stopper.

A powdery-material feeding device includes a hopper configured to reserve a powdery material, a transfer member configured to deliver and to discharge the powdery material fed from the hopper, a motor configured to drive the transfer member, a measuring instrument configured to measure a discharge amount of a powdery material delivered to be discharged by the transfer member, and a controller configured to control, while control according to the discharge amount of the powdery material measured by the measuring instrument is not conducted, a current applied to a coil of the motor to have a substantially constant amount, to control the discharge amount of the powdery material delivered to be discharged by the transfer member to have a required amount.

A method for unloading a payload at a loading station includes selecting the payload to be unloaded from different payloads and registering a total target quantity of the selected payload to be unloaded at the loading station as a target quantity unit, a current total quantity of the selected payload that has already been unloaded at the loading station as an actual quantity unit, a number of already performed unloading procedures corresponding to a quantity of the selected payload that has already been unloaded at the loading station, or a difference between the target quantity unit and the actual quantity unit.

A metering system for an agricultural vehicle includes meter rollers, each including protrusions driving flow of flowable particulate material in response to rotation of the meter roller. The metering system also includes a drive shaft driven in rotation and includes transmission assemblies that each correspond to a respective meter roller. Each transmission assembly includes a respective moveable gear actuatable to engage each of a plurality of gears to establish a respective gear ratio corresponding to one of a plurality of different speeds of the respective meter roller relative to the drive shaft.

The invention relates to a dosing apparatus for dosing bulk material into block forming elements, and for arrangement on a filling car of a filling apparatus of a block-making machine for manufacturing patterned blocks, in particular paving blocks. The filling car may be pushed forward and backward over block forming elements in a displacement direction, and a first bulk material component may be filled into the block forming elements with this car. The dosing apparatus comprises at least one filling box that has a lower outlet that may be opened and closed by means of a closure. A second bulk material component may be filled from the filling box into the block forming elements via the lower outlet.

A system (1) dispenses dosages of a powdery substance. It has a robotic handler (2), a weighing module (8) with a weighing pan (9), at least one storage rack (4) for holding a plurality of dispensing heads (3) and at least one storage rack (6) for holding a plurality of vials (5), a dosage dispenser unit (11) with a dispensing head receiver (12), a vial handling tool (17) and a dispensing head handling tool (18), a tool-docking station (19) for the handling tools, and a controller terminal unit (20). Different weighing pan adapters (15) adapt the weighing pan to different shapes and sizes of vials. Relative to a vertical working orientation, tlower portions of the weighing pan adapters are identical, to fit the weighing pan, but upper portions are different, to accommodate different shapes and sizes of vials. A station (16) is provided for storing the weighing pan adapters.

A device is provided for the controlled and precise delivery of powders, including cohesive powders, based on a fluidization technique to directly reduce inter-particle friction and using a fluidizing gas as an air-bearing. The device preferably includes no moving parts, no sealing gaskets or sealing surfaces. Unlike mechanically actuated valves, the powders dispensed by the current device do not experience mechanical shearing, thereby reducing wear and thus increasing the service life of the apparatus.
