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.

The present invention relates to the technical field of agricultural machines, specifically to a furrow opener of a wide seedling row seeder, which includes a frame, where a power device is arranged at the upper portion of the frame, two symmetrically arranged connecting plates are arranged at the lower portion of the frame, a furrow opener shaft is arranged between the two connecting plates, the furrow opener shaft is connected with the power device through a driving device, the furrow opener shaft is fixedly connected with a plurality of furrow opening blades uniformly distributed on the circumferential surface of the furrow opener shaft, a main body of the furrow opening blade is in shape of a rectangular plate, the furrow opening blade is formed by carrying out a twisting treatment on a plate-shaped structure, a head end of the furrow opening blade is vertical to the center line of the furrow opener shaft, a tail end of the furrow opening blade is in parallel with the center line of the furrow opener shaft, a bent tip is arranged at the tail end of the furrow opening blade, the bent tip is bent towards an advancing direction of the corresponding furrow opening blade, two sides of the furrow opening blade are respectively and fixedly connected with a baffle, the baffle is in shape of a circular ring, and the bent tip extends from the outer sides of the baffle. The furrow opener of a wide seedling row seeder of the present invention facilitates consistency of the widths and depths of opened furrows.

A ground drive hose routing system and method for a self-propelled agricultural product applicator utilize segments of a hose arrangement that are constrained to lie and move primarily in only one direction, to isolate horizontal hose movement related to track-width adjustment from vertical hose movement resulting from action of suspension members. For steerable wheels, an additional pivotable segment is utilized to accommodate turning motion while maintaining isolation between other primarily horizontally and vertically constrained movable segments of the hose arrangement.

A planting unit includes a seed meter for singulating and dispensing seed. Opening wheels or discs are included to create an opening in the field, such as a furrow. The unit includes one or more continuous tracks for supporting the row unit as it moves through the field. The tracks can be positioned on opposite sides. The tracks reduce compaction around the created furrow and provide better control of seed depth placement. One or more motors are included to operate the tracks to move the planting unit through a field for planting independent of a tow vehicle.

A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and a several spreading units. Each of the spreading units includes at least one pneumatically operated separating device, to or from which a separation air flow is suppliable or dischargeable, and a fertilizer application device. The spreading machine includes a conveying air-driven seed feeding device for providing seed from the seed hopper to the spreading units, and an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices. To refine a spreading machine that includes a plurality of consumers, the spreading machine includes at least two separate energy suppliers, in particular blowers or pumps, for providing the separation air flows to the separating devices, the conveying air to the seed feeding device, and the energy to the fertilizer supply device.

A twin row seed distributor body group is provided that enables twin sowing with a single seed distributor body of pneumatic sowing machines utilized in the agricultural industry. The twin row seed distributor body group contains at least one twin row seed distributor body provided for each sowing unit enabling synchronized sowing on two different sowing rows, at least one right and one left seeding disc, at least one shaft bearing group enabling the movement of seeding discs, at least one seeding disc motion shaft enabling the synchronized movement of the seeding discs, at least one modular main body inner bearing cover that enables fast mounting and maintenance of the disc shaft motion gear and disc motion gears operating inside the seed distributor body and also that forms a bearing for the seeding disc motion shaft, and a hinged seed discharge gate.
