Farm mechanical gearbox

Abstract

The invention relates to a farm mechanical gearbox. The farm mechanical gearbox comprises a gearbox body. A power input shaft, a power output shaft and a middle transmission shaft are arranged in the gearbox body. The power input shaft is connected with a motor. A first driving gear, a second driving gear and a first clutch are arranged on the power input shaft. The first driving gear is rotationally arranged on the power input shaft. The first clutch is arranged on the power input shaft. A first transmission gear, a second transmission gear and a second clutch are arranged on the middle transmission shaft. The second driven gear is rotationally arranged on the middle transmission shaft, and the second clutch is arranged on the middle transmission shaft. A transmission gear set is arranged between the power output shaft and the middle transmission shaft. According to the farm mechanical gearbox, different gears of the gearbox are switched through the two clutches, the size of the gearbox body does not need to be increased, the manufacturing cost of the gearbox is lowered, the problems that in the current gear switching process, gears are tightly engaged with one another, gear switching is difficult, and gear collision and damage happen are solved, and operation is flexible and convenient.

Description

Technical field [0001] The invention relates to a gearbox for agricultural machinery, in particular to a gearbox assembled on a cotton picker. Background technique [0002] Due to the structural design defects of the current cotton picker gearbox, the gearshift device is added on the basis of increasing the volume of the gearbox, and there are more accessories, which increases the weight of the gearbox. The assembly and disassembly process is more complicated. At the same time, it is not easy to operate and switch, and the service life is short. In addition, after the gearbox is used for a period of time, heat is generated in the box, which is not easy to diffuse to the outside and affect the use of the gearbox. Summary of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide an agricultural machinery gearbox with reasonable structural design, convenient operation and convenient switching. [0004] The technical scheme of...

Problems solved by technology

[0002] Due to the defects in the structural design of the current cotton picker gearbox, on the basis of increasing the volume of the gearbox, a shifting device is added, and there are many accessories, which increases the weight of the gearbox. The assembly and disassembly process is relatively complicated. At the same time, it is not easy to operate and switch, and the service life is short. In addition, after the gearbox is used for a period of time, the heat generated in the box is not easy to spread to the outside, which affects the use of the gearbox.
