A crawler self-propelled device

Abstract

The invention discloses a crawler self-walking device comprising a walking system (1), a power system (2), a control system (4) and a suspension system (7). The walking system (1) is composed of a chassis frame (11) and a walking wheel system (12). The walking wheel system (12) is mounted on a support arranged below the chassis frame (11). The power system (2) and the control system (4) are mounted above the chassis frame. The rear suspension structure is arranged behind the chassis frame. A walking gearbox, an engine, a power output transmission case are longitudinally arranged at the midpoint of the frame, and the gravity center of the frame keeps balanced in the horizontal direction. The engine is in rigid connection with the power output transmission case, and is in flexible connection with the frame, so that the vibration is low, and the reliability is high. The power output transmission case and the walking gearbox are connected to a hydraulic motor through a hydraulic pump, the structure is simple, the performance is stable, and the transmission efficiency is high.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crawler self-propelled device. Background technique [0002] The crawler self-propelled rotary tiller has only been developed in recent years. Due to its good adhesion, it shows good passability of paddy fields, especially in wet, muddy or harsh environments. It is small, compacts and damages the farmland lightly, and is especially suitable for operation in paddy fields in the south. Its unique characteristics in agricultural production cannot be replaced by wheeled tractors. 1. After the rotary tiller is attached, the transmission box is subjected to a rotating moment, so that the length of the two suspension arms cannot be too long, that is, the lifting range of the rotary tiller is small; 2. The suspension device is installed on the power output transmission box, and the two suspensions The short distance between the arms makes the left and right stability of...

AI Technical Summary

Problems solved by technology

The belt transmission structure is complex, easy to wear, large power loss, and inconvenient to replace the belt; 4. The triangular crawler is used, the climbing ability is weak, and the vibration is relatively large when walking on hard roads

Difficult to adapt to paddy fields, dry land, hills and other areas

[0003] Aiming at the disadvantages of low traction, poor stability, weak climbing ability, and large vibration when walking on hard roads in the prior art, the present invention makes further improvements
