A gearbox for a rotary cultivator with forward and reverse rotation and left and right steering functions

Abstract

The invention discloses a gearbox with the forward-and-reverse rotation and left-and-right steering functions for a rotary cultivator. The gearbox comprises an upper box body, a lower box body, a forward-and-reverse rotation mechanism and a left-and-right steering mechanism, wherein the upper box body and the lower box body are matched, the forward and reverse rotation mechanism is arranged in the upper box body, and the left-and-right steering mechanism is arranged in the lower box body. The forward and reverse rotation mechanism and the left-and-right steering mechanism are connected through chain wheels and a chain, and power of the upper portion of the gearbox is transmitted to the lower portion of the gearbox. According to the gearbox, the current situation that existing agricultural implements are single in functions is changed, the problem that an existing gearbox is difficult to steer and can not be matched with other agricultural implements for use in the using process is solved, the gearbox is multifunctional and simple, safe and reliable in operation, and purchase cost is saved for farmers.

Description

technical field [0001] The invention relates to a gearbox, in particular to a gearbox for a rotary cultivator that can be used in conjunction with a semi-trailer compartment, can realize multi-stage speed change, and has forward and reverse rotation and left and right steering functions. Background technique [0002] At present, with the vigorous promotion of agricultural mechanized production and the innovation and replacement of agricultural machinery and tools, agricultural machinery with a single function can no longer meet the existing agronomic requirements and agricultural production needs. The existing domestic rotary tillers that are articulated or directly connected to the engine are widely used in agricultural machinery. The gear realizes the speed change, and then transmits it to the sprocket connected to the hexagonal output shaft at the bottom through the chain in the middle part, so that the rotary tiller on the rotary tiller shaft can realize forward transmis...

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of this kind of rotary tiller are: first, because of its single function, it can only be used for the plowing of farmland, dry land and sugarcane land, and it cannot be used for agricultural implements because there is no steering mechanism and cannot be used with semi-trailers. Second, when the corner position is encountered during the plowing or dry land plowing process, since there is no left and right steering mechanism, it is necessary to manually separate the transmission of the rotary tiller to stop the rotation, and at the same time, it needs to be lifted manually. The handle of the rotary tiller makes the rotary tiller away from the soil to realize the steering. This action process is time-consuming and laborious, and it is easy to injure the operator, which is very dangerous

The single operation function and cumbersome steering operation of the machine have also affected the enthusiasm of farmers to purchase machines, hindering the development of agricultural automation
