A crawler belt over-ridge deformation device for a crawler-type farmland operation vehicle

Abstract

The invention discloses a caterpillar ridge crossing deformation device for a caterpillar farmland operation vehicle. The caterpillar ridge crossing deformation device is characterized in that a frame comprises a frame cross member and an auxiliary frame cross member, a driving wheel is mounted above one end of the 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 the frame, the certain end of the frame and the driving wheel are positioned on the same side of the caterpillar ridge crossing deformation device, a rear support wheel is mounted on the rear support frame, a deformation bearing frame is arranged above a deformation bearing wheel, a front deformation frame and a rear deformation frame which are structurally identical to each other are symmetrically arranged on two sides of the deformation bearing wheel, are respectively connected with the deformation bearing frame by telescopic mechanisms and are respectively connected with the frame, and bearing wheels are respectively mounted on the front deformation frame and the rear deformation frame. The caterpillar ridge crossing 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 running safety can be improved.

Description

technical field [0001] The invention relates to the technical field of crawler belt ridge drive deformation, in particular to a crawler belt ridge deformation device for a crawler-type farmland operation vehicle. Background technique [0002] Paddy fields in the south are often planted with rice, and the paddy fields are kept in a wet state for a long time, so the soil is soft and the mud feet are deep, which makes the operating machinery easy to slip and sink when working in the field. At present, crawler-type farmland operation vehicles are widely used in southern paddy field operation machinery 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; however, southern paddy fields are mostly in In hilly and mountainous areas, not only the field area is small, but the area of ​​a single field is 1000m 2 ~2000m 2 Mainly, and for the need of water storage, there is a separa...

[0002] Rice fields are often planted in southern rice fields, and the rice fields are kept in a wet state for a long time, so the soil is soft and the mud feet are deep, which makes the operating machinery easy to slip and sink when working in the field

At present, crawler-type farmland operation vehicles are widely used in southern paddy field operation machinery 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; however, southern paddy fields are mostly in In hilly and mountainous areas, not only the field area is small, but the area of ​​a single field is 1000m 2 ~2000m 2 Mainly, and for the need of water storage, there is a separated field ridge with a height of 15-25cm and a width of 20-30cm between the fields. The straight track will cause the tracked farmland operation vehicle to have a large inclination in the front and rear direction. Even if it crosses the field ridge with a height of about 20cm, it will cause the crawler type operation vehicle to have a maximum suspension of 80-100cm, which will seriously affect the crawler farmland. When the middle part of the track crosses the field ridge, the front of the tracked farmland operation vehicle goes down quickly, and the state of the vehicle changes sharply from head up to down, which endangers driving safety
