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 apparatus for biological control of agricultural pests and for reducing damage to crops is disclosed. The apparatus includes a rotatable container for holding biological organisms or material. The walls of the container include a series of openings through which the biological organisms or material can pass, dispersing the biological organisms or material over a target area when the container is rotated.

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.

A dispenser unit (1) for dispensing biological material, e.g. larvae or insects etc. The dispenser unit has a rotary arrangement (2) with a drive shaft (3) and a plurality of protruding vanes (4) positioned inside a housing (10) for encasing the rotary arrangement to form chambers (5) for containing biological material between respective neighbouring vanes and an inner wall (11) of the housing. A track (6) on the housing serves to engage with each vane or movable element to control the volume of the chamber between an inlet opening (20) in a top part of the housing and an outlet opening (21) in a bottom part of the housing. This allows the biological material to be received in the chambers at the inlet opening (20) and dispensed from the chambers (5) at the outlet opening (21) during rotation of the rotary arrangement. The dispensing unit is designed to provide for an expanding chamber volume as the chambers are being rotated from the inlet opening to the outlet opening. The dispenser unit has proven to provide a low mortality e.g. for dispensing living larvae. It can be transported by a drone or the like to spread biological material over a large area.

A spreader assembly to distribute materials on a ground surface, including a container to hold the materials, a frame affixed to the container, a beater assembly supported by the frame that receives the materials from the container and processes the materials to obtain processed materials, and a spinner assembly that receives the processed materials and expulses the processed materials from the frame onto the ground surface. The beater assembly includes a pair of rotating elements that blends the materials to produce the processed materials, and a deflector located between the pair of rotating elements configured to prevent the formation of agglomerates in the processed materials.

A planting system includes a seed spreading assembly mounted on an unmanned aerial vehicle (UAV). The seed spreading assembly includes a hopper having a hopper cavity, and an agitator. The agitator is coupled to the hopper, and includes an agitator frame in the hopper cavity. The agitator frame includes one or more agitator members coupled to a support subframe. The one or more agitator members are more flexible than the support subframe. Other embodiments are also described and claimed.

A swing disc spreader includes a swing disc which is arranged to be rotatable; and a swing driving mechanism, which is in transmission connection to the swing disc and used for driving the swing disc to swing reciprocatingly, the swing disc being configured to be in contact with materials during a swinging process so as to spread the materials outwards. In the technical solution provided in the present application, the swing disc spreader can achieve the spreading operation of materials simply by using one swing disc, such that the swing disc spreader has a simpler structure, achieves a reduced overall size and a relatively uniform spreading width, thus reducing the cost.
