Description

Transmission device for hill planter

Technical Field

The utility model relates to the technical field of agricultural machinery, especially, relate to a transmission for hill-drop planter.

Background

The hill planter is a planting machine for planting seeds in holes according to a certain row spacing and a certain hill spacing. The hill planter mainly comprises a rack, a seed box, a seed sowing device, a furrow opener, an earthing pressing device and the like, and the hill planter mainly comprises the rack, the seed box, the seed sowing device, the furrow opener, the earthing pressing device and the like. The frame is composed of a main beam, a traveling wheel and a suspension bracket, and the seed box, the seed sowing device, the furrow opener, the soil covering device, the roller and the like form a sowing unit. The seeding single body is connected with the main beam through a four-bar copying mechanism and can fluctuate along the ground. The number of the single bodies is equal to the number of the seeding rows, and the seeding device on each single body is driven by the walking wheels or the press wheels of the single bodies. The hole distance can be adjusted by changing the chain wheel. When the seed box is in work, the travelling wheels drive the seed sowing wheels to rotate through the transmission chains, the seed sowing devices discharge seeds in the seed box into holes or single seeds, the seeds fall into seed grooves formed by the seed conveying pipes through the furrow openers, then the soil covering devices cover soil, and finally the pressing devices cover and compact the seeds. The main working part of the hill planter is to realize the single-seed or hole-forming arrangement of seeds by a hole forming device.

The transmission mechanism of the fertilizer box of the hill planter is used for controlling a fertilizer feeding switch positioned below the fertilizer box to achieve the function of closing the switch, thereby controlling the application state of the fertilizer. The fertilizer box is generally composed of a connecting rod, a flywheel and other transmission components, and a driving gear drives the flywheel connecting rod to rotate so as to enable a switch rotating shaft of the fertilizer box to rotate to realize switch closing.

This kind of mode needs the length of changing different members such as connecting rod when adjusting to the closed degree of blowing switch when in actual use to realize the adjustment of swing range to the size of control blowing volume makes the operation process comparatively inconvenient, wastes time and energy.
