A crawler support deformation device for a crawler-type farmland operation vehicle

Abstract

The invention discloses a caterpillar support deformation device for a caterpillar farmland operation vehicle. The caterpillar support deformation device is characterized in that a driving wheel is mounted above one end of a frame cross member, and a front support wheel is mounted below the other end of the frame cross member and is connected with a hydraulic cylinder mounted on the frame; a rear support frame is welded on the lower side of a certain end of a frame, the certain end of the frame and the driving wheel are positioned on the same side of the caterpillar support deformation device, a rear support wheel is mounted on the rear support frame, a deformation bearing frame supporting seat which is used for mounting a deformation bearing frame is welded in the middle of the frame, a front deformation frame and a rear deformation frame which are respectively connected with the frame and are structurally identical to each other are symmetrically arranged on two sides of the deformation bearing frame, and bearing wheels are mounted on the front deformation frame and the rear deformation frame; telescopic cylinders are arranged in the deformation bearing frame supporting seat, and springs sleeve the telescopic cylinders. The caterpillar support deformation device has the advantages that the hydraulic cylinder can be contracted and extended when the caterpillar farmland operation vehicle crosses a ridge, so that the shape of the middle of a ground-contact caterpillar can be changed, the inclination height of the caterpillar farmland operation vehicle can be lowered, and the operation safety can be improved.

Description

technical field [0001] The invention relates to the technical field of crawler belt drive deformation technology, in particular to a crawler belt support deformation device for a crawler-type farmland operation vehicle. Background technique [0002] The paddy fields in the south are mostly located in hilly areas, not only the field area is small, but the area of ​​a single field is 1000 2 ~2000m 2 Mainly, and for the need of water storage, a separating ridge with a height of 15-25cm and a width of 20-30cm is built between the fields; at the same time, paddy fields in the south are often planted with rice, and the paddy fields are in a humid state for a long time, so the soil is soft. The mud foot is deep, and the operating machinery is easy to slip and sink when working in the field. At present, crawler-type farmland operation vehicles are widely used in rice field operation machinery in the south due to the use of crawler drive, large grounding area, small grounding speci...

AI Technical Summary

Problems solved by technology

At present, crawler-type farmland operation vehicles are widely used in rice field operation machinery in the south due to the use of crawler drive, large grounding area, small grounding specific pressure, good cross-ditch performance, and low damage to farmland and roads. It is a straight track on the ground area. When the tracked operating vehicle crosses the field ridge, the tracked operating vehicle tilts greatly in the front and rear directions. A suspension of 80-100cm will be generated, which will seriously affect the safety of the crawler-type farmland operation vehicle when crossing the ridge; especially when the middle part of the crawler crosses the field ridge, the head of the crawler-type operation vehicle will quickly fall down, and the vehicle state will change from head-up to downward. Make a sharp turn and endanger driving safety
