Gearbox for corn harvester for pulling seedlings and cutting stalks

Abstract

The invention provides a gearbox for a corn harvester for pulling seedlings and cutting stalks, comprising a box body and a power input shaft arranged on the box body, wherein a cutting input rack wheel, a cutting power output gear shaft, a seedlings-pulling input pinion, a sun gear shaft loaded with the rack wheel, a planet wheel shaft loaded with a planet wheel, an inner gear ring of the gearbox, a safety clutch and a seedlings-pulling power output shaft are additionally arranged, the cutting input rack wheel is fixedly arranged on the power input shaft and is engaged with the cutting power output gear shaft; the seedlings-pulling input pinion is fixed on the end of the power input shaft and is engaged with the rack wheel; the planet wheel is located between the sun gear shaft and the inner gear ring of the gearbox and is engaged with the sun gear shaft and the inner gear ring of the gearbox respectively; the planet wheel is located between the sun gear shaft and the inner gear ring of the gearbox and is engaged with the sun gear shaft and the inner gear ring of the gearbox; the other end of the planet wheel shaft is fixed on the input end of the safety clutch and the output end of the safety clutch is fixedly connected with the seedlings-pulling power output shaft. After the invention is adopted, the integration of pulling seedlings, picking ears and cutting stalks is achieved; the gearbox can automatically reset after overloading, thereby being safe and reliable.

Description

technical field [0001] The invention provides a gearbox for chopping stalks of a corn harvester and belongs to the technical field of agricultural machinery. Background technique [0002] At present, the reeling and stalk chopping devices of the existing domestic corn harvesters are configured separately, and the integration of stalk reeling and chopping cannot be realized, so there are disadvantages such as low efficiency, high energy consumption, and large noise. Most of the existing transmission gearboxes are not equipped with safety clutches. Due to the complex farmland operation environment, if the header is blocked or the load is too large, it is easy to cause the chopping knife to break or the gear to be broken due to overload, which will affect the safety of the machine and bring inconvenience to agricultural production. Thereby delaying the best farming time. Contents of the invention [0003] The purpose of the present invention is to provide a corn harvester st...
