Method for a centrifugal spreader to precisely spread particulate material across an entire field with increased application rate, swath width and driving speed by utilizing a tiered disk spinner arrangement fed by a conveyor and guided by a material divider and an adjustable chute moveable in rotation around the spinner disk to achieve a desired symmetrical or asymmetrical spread pattern.

An apparatus 100 is described for precision volumetric metering and distribution of solid inputs used in agriculture, the apparatus being coupled to sowing devices and comprising a frame 1 with a through-hole 12 through which an axle 3 radially locked to a turbine 4 extends, the axle 3 driving the metering turbine 4; an opening 21 in the floor of the frame leads the agricultural input 31 to the output nozzle 13. The geometry of the turbine 4 comprises cutouts of various shapes which form chambers 5 for distributing the agricultural input 31 uniformly. A labyrinth 25 is formed by the frame 1, the inner grater 6 and the turbine 4. The structural geometry of the turbine 4 only allows metering of the input 31 while the turbine is rotating, while the agricultural input 31 is retained inside and on the turbine 4 when the turbine does not rotate.

The present invention is directed to an applicator having an agricultural product pneumatic conveying system which meters and transfers particulate material from one or more source containers to application equipment on demand. The pneumatic conveying system employs supply lines connected between the source containers and delivery nozzles that operate to move and mix the particulate material from one of the source containers or tanks. A rotary distributor is connected between each of the supply lines and the delivery nozzles and includes a rotating shaft to divert the particulate material relatively evenly between the delivery nozzles. The rotary distributor is disposed in alignment with the supply line to require less air flow for the distribution of the particulate material into the delivery nozzles and to significantly reduce the profile of the applicator in the folded or transport configuration.

A material spreader which is suspended beneath an airborne helicopter and which includes a container for flowable materials such as seeds, fertilizers or chemicals. The container has a discharge opening formed in its lower end which has a vertically movable valve positioned therein. The valve is controlled by the pilot of the helicopter from within the cockpit of the helicopter so that the application rate of the material may be varied without the necessity of landing the helicopter.

An apparatus for biological control of agricultural pests and for reducing damage to crops. The apparatus includes a container for holding biological organisms or material. The container also includes first and second ends and an opening formed at the first end for receiving the biological organisms. The apparatus has a dispensing port disposed at the second end for dispensing the biological organisms over a target location. The apparatus further includes an auger, driven by a motor and having a plurality of spiral like wire brushes, said auger mounted to and driven by a first motor; a spreader motor mount having a motor mount holding area for holding a second motor, the spreader motor mount having a motor mount connection area for connecting to the second end; and a spreader agitating device used for spreading the biological organisms or material over the target location.

An applicator including: a frame with hopper mounted thereon to hold and dispense a granule product, the hopper including an electronically controlled gate(s); a tank to hold a liquid product; a electronically controlled spray tip(s) to dispense the liquid product; a spray pump located between the tank and spray tip(s); an operator control interface for receiving input from an operator; a control coupled to the operator control interface, the electronically controlled gate(s), and the spray tip(s), where the control receives input, dispenses the liquid or granule product based on the input received from the operator control; where when the liquid product is dispensed, the control provides a signal to the spray tip(s) to regulate a flow of the liquid product, and when the granule product is dispensed, the control provides a signal to the electronically controlled gate(s) to regulate a flow of the granule product.

The invention relates to a disc spreader comprising a frame consisting of a base frame (11) and an auxiliary frame (21), wherein a container (61) is secured to the base frame (11) and a spreader disc (22) is secured under the container (61) on the auxiliary frame (21), wherein, according to the invention, a dosing unit (12), preferably having a cellular wheel sluice (18), is arranged on the base frame (11) under the container (61), said dosing unit having an outlet (14) at the bottom for a collection hopper (23), wherein the collection hopper (23) is secured to this outlet (14) of the dosing unit (12) and the auxiliary frame (21) is secured on the base frame (11) by means of a quick-closure (15, 25). In this way, it is possible to provide a distributer (32, 32a) which can be connected to the outlet (14) of the dosing unit (12) after removal of the auxiliary frame (21) and the collection hopper (23), such that the disc spreader can be converted into a seeder.

A distributor includes two distributor disks, which are driven rotatably by a drive train, to be attached to a power take-off shaft of a traction unit or of a tractor. The drive train includes a central input shaft driving a cross shaft to drive distributor disks via a central gear. The distributor disks can be rotated at different speeds with a reducing gear with variable output speed, arranged downstream of the central gear. The reducing gear is configured as a mechanical coaxial transmission with an input shaft connected to the cross shaft and an output shaft arranged coaxially to the cross shaft. A speed reduction ratio is changed by an adjusting element between a normal position, with an input speed of the input shaft corresponding to the output speed of the output shaft, and a speed reduction position with the input speed not equal to the output speed.

A sectional control apparatus and method prompts the operator of an implement when the implement, or portion thereof, is traversing over land that has already been seeded and/or disturbed. The apparatus includes a GPS or GNSS receiver that communicates with a GPS or GNSS system and a controller that maps movement of the implement so that real-time positional data for the implement can be compared to the movement map. When the position of the implement, or portion thereof, is detected as moving over previously seeded and/or disturbed land, the controller activates an alert mechanism in the operator cab of the implement to notify the operator that sectional control, i.e., shutting down metering of product or raising the tool bar, needs to be implemented.

An electric handheld broadcast spreader with pattern and speed controlling baffled skirt detachably attaches to a conventional spreader mechanism to disperse particles in a controlled, directional manner within a proximal coverage area with two hands. A broadcasting/dispersing skirt receives particulate material from a conventional spreader. The inner volume of broadcasting/dispersing skirt comprises upper layer baffles, with upper gaps forming between each upper layer baffle; lower layer baffles, offset from the upper layer baffles, with lower gaps forming between each lower layer baffle; and multiple vertical deflector vanes disposed perpendicular to lower layer baffles. Discharged particulate material strikes the surface of the baffles, before passing through gaps. The particulate material traveling in a lateral direction strikes the deflector vanes and outlet edge of broadcasting/dispersing skirt. This controls velocity and direction of dispersed particulate material, causing particulate material to be confined within a close pattern coverage area on ground surface.
