A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a metering assembly removably received within the interior space of the housing. The metering assembly is configured to convey agricultural product through the metering device. The metering assembly comprises a rotatable sub-shaft, a first metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, a second metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, and a dividing element positioned on the sub-shaft between the first metering wheel and the second metering wheel.

A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a gate assembly removably received within the interior space of the housing. The gate assembly is configured to guide agricultural product through the housing. The gate assembly comprises a product gate comprising an arcuately-extending gate valve. The product gate at least partially defines a channel within the interior space of the housing through which agricultural product can flow. The gate assembly further comprises a gate key configured to selectively secure the product gate within the housing. Rotation of the gate key is configured to cause a corresponding rotation of the product gate.

A motor-driven single-seed-ejection sowing device includes a housing, a seed metering roller, a seed brush, a seed metering mechanism and a power mechanism. The housing includes a power compartment and a seed compartment. The surface of the seed metering roller includes seed grooves having spaces for accommodating a single seed. The seed metering mechanism includes a spring, a striking tube, a piston and the piston tube. The piston and the piston tube are arranged for axial movement inside the striking tube. The power mechanism includes a control unit and a drive unit. The control unit includes the motor, the drive panel, the Hall sensor and the magnet. The magnet is set on the striking tube. The Hall sensor and the drive panel are connected to the motor, and the motor drives the seed metering roller and seed metering mechanism by the drive unit.

A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

A seed metering system, for use on a row crop planter, selects individual seeds from a seed reservoir and dispenses the seeds singularly at a controlled rate. A direct drive seed metering system includes a seed disc having a plurality of suction apertures with a recessed pocket adjacent to an aperture. The recessed pockets act to agitate seeds in the seed reservoir and to direct seed flow towards the apertures. A seed path relief system aids in the placement of the seeds such that they are released from an outer edge of the seed disc. An adjustable seed singulator is mounted adjacent to the face of the seed disc where inner and outer blades are adjusted radially to compensate for the singulation of various seed sizes and shapes. The seed disc is driven via engagement of an internal gear with the external gear of an independent drive motor.

A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

A seeding machine includes a seed metering system and a seed delivery system in communication with the seed metering system. The seed delivery system includes a housing having a first opening for receiving seed from the seed metering system and a second opening through which seed is discharged. The seed delivery system also includes a conveyor forming a loop with a fixed length and positioned within the housing. The conveyor is disposed around a first drive pulley and a second idler pulley. The conveyor is deformable in order to retain seed at any point along the fixed length.

A rotor apparatus for feeding granular or powdered material in an agricultural implement, the rotor apparatus being designed to be received in a partially cylindrical feeder space of a feeder device for volumetric feeding. The rotor apparatus comprises an insert part, which in size and shape is adapted to be inserted into the feeder space and to substantially prevent air from passing the insert part when this is inserted into the feeder space, and a rotor, which is rotatable relative to the insert part. The insert part defines a rotor space, in which the rotor is rotatable, and the rotor is together with the insert part designed to provide an air lock. The insert part comprises a wall portion interacting with the rotor and located radially outside the radially outermost portion of the rotor.

A spreader device includes a hopper axially mounted above a generally circular hollow tube, the generally circular hollow tube forming a semi-circular hopper floor of an interior area formed by the hopper, and a drive motor assembly attached to the hopper and operable to rotate the generally circular hollow tube within at least a portion of the interior area formed by the hopper.
