Double steering shaft gearbox of walking machine for agriculture or constructional engineering

Abstract

The invention discloses a double steering shaft gearbox of a walking machine for agriculture or constructional engineering, which comprises a box body, a steering shaft and a driving wheel shaft or a driving reduction shaft. Control ends of two steering shifting forks on the steering shaft are respectively provided with control pressing wheels; the control pressing wheels are respectively arranged at the upper ends of control levers on the box body; the lower ends of the control levers are connected with each other through a tension spring; and the control pressing wheels are respectively pressed against left and right steering operating levers. The double steering shaft gearbox is characterized in that: one side of the steering shaft is additionally provided with an auxiliary steering shaft which is parallel to the steering shaft; an auxiliary central drive gear on the auxiliary steering shaft is meshed with a central drive gear on the steering shaft; and auxiliary steering output gears at both ends of the auxiliary steering shaft are respectively meshed with driving gears at both ends of the driving wheel shaft or the driving reduction shaft. The double steering shaft gearbox has the advantage of capability of making the walking machine for the agriculture or constructional engineering have smaller turning radius, rapidly turning, higher efficiency, easy and convenient operation, and difficulty of falling into the mud ground.

Description

technical field [0001] The invention relates to a mechanical walking speed change device, in particular to a double-steering-shaft gearbox for walking machinery used in agricultural or construction engineering. Background technique [0002] The structure of the gearbox used in the existing agricultural or construction engineering walking machinery, such as the gearbox equipped with the micro-tiller and tiller of the known model of 1WG6, its structure includes a box body, and is arranged in the box body. The power input shaft, gear shaft, reverse gear shaft and steering shaft, as well as the driving wheel shaft or the driving reduction shaft, each shaft is meshed and transmitted through the corresponding matching gears, and the output gears at both ends of the steering shaft are connected to the driving wheel shaft or the drive shaft. The drive gears at both ends of the reduction shaft are meshed, and the control ends of the two steering forks on the steering shaft are respec...

Problems solved by technology

[0004] The walking mechanism equipped with a gearbox of this structure has a large turning radius and a large forward distance. If it is used on a harvester, especially if it is used on a crawler-type walking wheel walking mechanism, due to the dense seedlings in the rice field, In order to avoid crushing the rice, the forward distance and turning radius of the harvester should not be too large when turning. Usually, the mechanical device needs to be operated two or three times to complete the turn, which consumes a lot of time and is inefficient; It is easy to get stuck in the mud, and the operation is not flexible, which brings great trouble to the work
