Novel walking device for halftrack tractor chassis

Abstract

The invention discloses a novel walking device for a halftrack tractor chassis. The device comprises a track walking mechanism, wherein the outer side of the track walking mechanism is in contact connection with a non-slip track, the inner side of the joint between the track walking mechanism and the non-slip track is movably provided with a protective mechanism, both ends of the track walking mechanism are provided with idler wheels, the idler wheels are connected with each other through a connecting rod, a connecting spring is embedded in the middle of the connecting rod, the right side of the connecting spring is provided with a supporting mechanism, the top of the supporting mechanism is provided with a first pulley and is connected with a transverse rod at the lower side through a metal rod, and both ends of the transverse rod are movably connected with a second pulley and a third pulley. The novel walking device for the halftrack tractor chassis has the advantage that the protective mechanism is arranged, the internal idler wheels press a pressure-bearing spring at the lower side of the non-slip track while rotating, the pressure-bearing spring drives a connecting buckle to move downward, thereby driving a pull rod to move, the pull rod drives a rotating gear at the outer side to rotate, and the rotating gear drives a protective plate at the outer side to cock, so that less mud and dust at the outer side enter the inner portion of the non-slip track.

Description

technical field [0001] The invention relates to the technical field of agricultural devices, in particular to a new type of walking device used for the underframe of a half-track tractor. Background technique [0002] Crawler tractor is also called "chain track tractor" or "crawler tractor", which is a kind of tractor. The traveling device is composed of a guide wheel, a follower wheel, a supporting wheel, a driving wheel and a crawler belt. When running, the driving wheel wraps around the track and circulates, and the supporting wheel rolls forward or backward on the track of the track, which has the advantages of small pressure per unit area of ​​the soil and good adhesion to the soil (not easy to slip). The soft terrain has better passing performance and high traction efficiency. [0003] However, when the track is walking on a relatively muddy road, the outer soil can easily enter the inside of the track, increasing the weight of the track itself, increasing fuel consu...

AI Technical Summary

Problems solved by technology

[0003] However, when the crawler is walking on a muddy road, the outer soil can easily enter the inside of the crawler, which increases the weight of the crawler itself, increases fuel consumption, and easily leads to the breakage of the crawler and the blockage of the internal roller mechanism.
