The invention provides a pressing type three-gear adjusting mechanism for seed and fertilizer sowing and applying amount, and belongs to agricultural machinery. A driving chain wheel and a groove-shaped driving shell are fixedly arranged on a driving shaft; a first-gear inner gear ring, a second-gear inner gear ring and a third-gear inner gear ring are fixedly arranged on the inner wall surface ofthe groove-shaped driving shell; a follow-up shell is fixedly arranged outside the third-gear inner gear ring; a rotary power output shaft with a power output connecting sleeve is inserted into the groove-shaped driving shell and the follow-up shell in an axial moving mode; a first-gear cylindrical gear, a second-gear cylindrical gear, a third-gear cylindrical gear and a gear adjusting and controlling plate are sequentially and fixedly arranged on the rotary power output shaft; a second-gear adjusting boss, a third-gear adjusting boss, a sawtooth-shaped gear adjusting auxiliary boss, a second-gear locking clamping groove and a third-gear locking clamping groove are arranged on the gear adjusting and controlling plate; and a second-gear pressing rod with a second-gear vertical locking pressure spring and a second-gear locking clamping block, a third-gear pressing rod with a third-gear vertical locking pressure spring and a third-gear locking clamping block and an auxiliary pressing rodwith an auxiliary pressure spring and a driving block are assembled on the follow-up shell. The pressing type three-gear adjusting mechanism is unique and reasonable in structure, high in applicability and high in use efficiency.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operating mechanism with adjustable seeding and fertilizer application rate. Background technique [0002] Existing sowing and fertilizing implements all adopt the rotating power of its implement ground wheel when the implement walks to directly drive the sowing shaft and the fertilizing shaft to rotate through the chain and sprocket drive system to complete the sowing and fertilizing operations. Since the transmission ratio between the ground wheel of the machine and the sowing shaft and the fertilizing shaft cannot be adjusted, the above-mentioned existing drive structure cannot adjust the amount of crop sowing and fertilization according to the agronomic requirements. Low and many other technical defects. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the above-mentioned prior art and combine the actual needs of agricultu...
