A crawler type rotary tiller

Abstract

The invention relates to the technical field of agriculture and forestry machines, in particular to a crawler type rotary cultivator. The crawler type rotary cultivator comprises a chassis device, a power system, a control system and a rotary cultivation device. The chassis device comprises a rack, a first wheel axle is arranged on the rack, crawler driven wheels are arranged at the two ends of the first wheel axle, a gearbox is arranged at the rear end of the rack, crawler driving wheels are arranged on an output shaft of the gearbox side, and the crawler driving wheels and the crawler driven wheels are sleeved with crawlers. The power system comprises an engine fixed to the rack, a hydraulic pump, a first belt wheel fixed to a rotary shaft of the hydraulic pump, a second belt wheel fixed to an output shaft of the engine, and a belt wheel engagement and disengagement assembly and a first chain wheel fixed to a shaft I of the gearbox. The control system comprises a first handle bar and a second handle bar. The rotary cultivation device comprises wallboards, a first rotary cultivation shaft and a second rotary cultivation shaft fixed to the wallboards, a third chain wheel, a fourth chain wheel, a first engagement and disengagement wheel, a second engagement and disengagement wheel, a third engagement and disengagement wheel, a fourth engagement and disengagement wheel and a supporting pipe fixed to the first rotary cultivation shaft, and a fifth chain wheel and multiple tool assemblies fixed to the second rotary cultivation shaft. The crawler type rotary cultivator is special in design, convenient to adjust, high in automation degree, high in rotary cultivation work efficiency, convenient to operate and high in environment adaptability.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry machinery, in particular to a crawler-type rotary tiller. Background technique [0002] At present, the agricultural and forestry industry is limited by the rugged terrain and diverse operating environments. It is difficult for rotary tillage machines to walk in this environment, and the movement is restricted. At the same time, due to the narrowing of the space after planting, it is inconvenient to transfer the position of the rotary tiller and it is difficult to complete. Weeding, plowing, digging pits and other operations have poor rotary tillage effects and cannot meet the requirements of most intensive farming and forestry. Therefore, most operations still need to use manual labor to overcome the restrictions on the operation activities of the above-mentioned rotary tiller, resulting in low efficiency , the effect is poor, time-consuming and labor-intensive, which hinders th...
