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

Embodiment Construction

[0040] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0041] Such as Figure 1 to Figure 11As shown, a self-propelled device includes a walking system 1, a power system 2, and an operating system 4. The walking system 1 is composed of a chassis frame 11 and a walking wheel train 12, and the walking wheel train 12 is installed on a bracket below the chassis frame 11. Above, the power system 2 and the steering system 4 are installed above the chassis frame. The front end of the supporting beam 113 of the chassis frame 11 is welded with a support seat 111v, the front end between the two supporting beams 113 is welded with a front splayed beam 115, and the rear end is welded with a rear splayed beam 114. The surface is on a plane; the right side of the splayed beam is welded on the right longitudinal beam 111a of the upper frame, and the right longitudinal be...

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...
