Driving device of seed or fertilizer discharging device

Abstract

The invention discloses a driving device of a seed or fertilizer discharging device. The driving device comprises a land wheel, a land wheel frame and a rack connecting base, wherein the land wheel and a main shaft of the seed or fertilizer discharging device have a transmission relation; the land wheel is mounted on the land wheel frame; the rack connecting base is used for connecting a rack of an agricultural machine; the land wheel frame is rotatably mounted relative to the rack connecting base; a pressure mechanism is arranged between the rack connecting base and the land wheel frame; andthe pressure mechanism is used for enabling the land wheel to keep contact with the ground. According to the driving device of the seed or fertilizer discharging device disclosed by the invention, theland wheel is arranged, and the transmission relation between the land wheel and the main shaft of the discharging device is established, so that the relation between a moving distance of the agricultural machine and the number of rotating turns of the main shaft of the discharging device can be established, and therefore, whether materials discharged by the discharging device are uniformly spread or not is not affected by an operation speed of the agricultural machine, the problem that control is complex when the main shaft of the discharging device is independently driven and controlled isavoided, hardware and control cost can be saved, operation is reliable, and a fault rate is low.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a driving device for a seed or fertilizer discharge device. Background technique [0002] Agricultural machinery is used to sow agricultural materials such as seeds and chemical fertilizers in the land. In order to realize the quantitative spreading of seeds or chemical fertilizers, agricultural machinery is equipped with a discharge device. The discharge device can discharge quantitative For materials, in order to spread the agricultural materials discharged by the discharge device evenly in the land, it is necessary to match the running speed of the main shaft of the discharge device with the moving speed of the agricultural machinery. In the prior art, the agricultural machinery is generally driven by a tractor to carry out the sowing operation , and the running speed of the tractor is very unstable. To achieve uniform spreading of agricultural materials, the requirements...

[0002] Agricultural machinery is used to sow agricultural materials such as seeds and chemical fertilizers in the land. In order to realize the quantitative spreading of seeds or chemical fertilizers, agricultural machinery is equipped with a discharge device. The discharge device can discharge quantitative For materials, in order to spread the agricultural materials discharged by the discharge device evenly in the land, it is necessary to match the running speed of the main shaft of the discharge device with the moving speed of the agricultural machinery. In the prior art, the agricultural machinery is generally driven by a tractor to carry out the sowing operation , and the running speed of the tractor is very unstable. To achieve uniform spreading of agricultural materials, the requirements for the spindle speed of the discharge device are very high, and it is difficult to control the spindle speed of the discharge device.
