A sowing element (1) for agricultural precision sowing machines (100) comprising a seed selection device (10) which includes a casing (10a) and a perforated disc (18) which is caused to rotate in the casing, a pressurization device associated with the casing in order to subject opposite faces (18a, b) of the disc to a pressure differential, an opening (16) in the casing which is for ventilating one of the faces of the disc and which is or can be pneumatically connected to a filtration system (42) or a remote intake system. In this manner, the introduction of sand and powder inside the seed selection device is prevented.

A pneumatic seed delivery system is provided for use with planter for row-crop planting an agricultural field in which the pneumatic seed delivery system may use high pressure air to accelerate seeds that are singulated from a seed meter to match ground speed when planting. The pneumatic seed delivery system includes an air accelerator arranged downstream of a release location of the seed meter. The air accelerator may define a pneumatic device such as an air conveyor or air amplifier that merges a primary airflow with a controllable supplemental airflow to provide a correspondingly controllable combined airflow that carries and accelerates the singulated seeds so that the seeds can be released with a rearward horizontal seed velocity component that approximates a forward ground speed of the planter to reduce seed tumble.

Disclosed is a manual granule spreader including: a main body including a wheel and a handle bar; a hopper having a plurality of discharge chutes; a spreading module having a spreading roller so as to spread the granules via first spreading means; a power transmission means. According to the granule spreader, manpower applied to the wheel is used to spread granules in the hopper in a predetermined amount in a single direction or opposite directions for drill seeding or for broadcast seeding, whereby workforce is saved, granules are prevented from being wasted, and the direction, angle, and length of the spreading means are adjusted, and a flexible driving wire is used to transmit power for spreading granules, which allows a vertical spreading position of the granules to be easily controlled by a vertical position adjustment of the hopper.

A work vehicle includes a delivery system with a run. The run includes an upstream flow structure having an inlet that is configured to receive metered commodity and a suction generator structure with a flow passage that is in fluid communication with the inlet. The flow passage includes a venturi profile with a restricting section and an expanding section. Furthermore, the run includes a downstream flow structure configured to receive the metered commodity via the flow passage and an airstream that conveys the metered commodity in a downstream direction through the downstream flow structure. A compressed air source is configured to provide pressurized air through the flow passage to create suction to suck the metered commodity away from the metering system and toward the downstream flow structure.

An agricultural machine includes a seeding system comprising a plurality of planting units, each planting unit configured to meter and deliver seed and a control system configured to obtain a seed planting model that identifies a plurality of seed planting locations on a worksite, identify a machine path on the worksite, identify, based on the machine path, a set of the seed planting locations for each of the planting units, and control each planting unit to deliver seeds to the set of seed planting locations identified for the planting unit.

A method for adjusting a seed depth associated with depositing a seed within a furrow in a field during a planting operation of an agricultural implement determining, by a computing device, a target seed depth based on a moisture content of the soil within the field. The method also includes sensing, by the computing device, a seed depth parameter indicative of a seed depth of the seed relative to a ground surface of the field. The method further includes comparing, by the computing device, the seed depth parameter to a target seed depth parameter that describes the target seed depth. In addition, the method includes initiating, by the computing device, a control action configured to adjust the seed depth parameter towards the target seed depth parameter.

The present invention relates to a planting tool, comprising a tube element with an inlet end and an outlet end. It further comprises a ground support rotatably connected to the tube element via a pivot point. The ground support comprises a first part with a pedal area and a second part with a hatch area, a mechanism comprising a first clamp and a second clamp, wherein the mechanism in an open state prevents movement between the hatch area and the outlet end and maintains the hatch area at a distance from the outlet end by means of contact between the first and second clamp, and in a closed state prevents movement between the hatch area and the outlet end and maintains the hatch area in contact with the outlet end, and the first clamp comprising a switch allowing a user to change position of said first clamp to switch the state of the mechanism from the open state to the closed state.

A sowing coulter arrangement comprises a suspension device for mounting the sowing coulter arrangement on a machine frame; a coulter frame connected to the suspension device for mounting components of the sowing coulter arrangement thereon; and a coulter disk. The arrangement further comprises a furrow closer pivotally mounted on the coulter frame; a metering device for dispensing the material to be distributed; a seed tube for transporting the material to be distributed from the metering device to a seed furrow; and a catching element for catching the material disposed downstream of the outlet of the seed tube. The metering device, the seed tube, and the catching element form a unit and are mounted on a carrier that is pivotably affixed to the coulter frame, whereby an arrangement of an outlet of a seed tube in relation to a catching element is at all times kept largely constant.

Provided is a seeder assembly for an aerial vehicle as shown and described. The distribution assembly includes a frame selectively attachable to an aerial vehicle and at least one distribution device attached to the frame. The distribution device having a body defining a cavity to receive a plurality of products and a barrel to discharge the plurality of products. A control device configured to communicate with the aerial vehicle and the distribution device to coordinate the timing that products are discharged and a spacing of a subsequent discharged product relative to the speed of the aerial vehicle. A system, method, and cartridge device associated with the distribution assembly are also contemplated by this disclosure.
