Abstract
The utility model discloses a small crawler tractor belonging to farmland operating machinery, in particular a crawler tractor. The small crawler tractor comprises an engine, a speed reducer, and a crawler. The utility model is characterized in that the pentagonal frame is loaded with the engine and the speed reducer. The crawler driving wheel is fixed on the frame through a bearing; the bottom of the frame is mounted with a supportive wheel group, the outside of the frame is arranged with a guide wheel; the crawler is mounted around the outside circumferences of the supportive wheel, the guide wheel, and the driving wheel; and a joystick and a hanger are fixed on the frame. The crawler of the small crawler tractor is on the outside of the machine body, the engine speed reducer and the driving device are mounted on the pentagonal frame.Although the overall size is small, however the crawler is long and walking is convenient, the climbing ability is strong, hence the tractor is suitable for operating in terrace of hilly area and running on hilly path. As the contact area between the crawler and earth is big while in operation, the tractor is suitable for operating in soft field or farmland with water.
Description
Affiliated technical field
The utility model belongs to farm working machinery, particularly track type tractor.
Background technology
Crawler-tread tractor has good farmland operation performance, be particularly suitable for soft or operation in the farmland of water arranged in soil property, its advantage is a not comparability of common wheel track formula trac., but general track type tractor volume is big, is not suitable for little plot and the terraced fields operation of hills, mountain area.
Summary of the invention
The purpose of this utility model provides a kind of technical scheme that is applicable to the baby track-layer of little plot and hills terraced fields operation.
The technical solution of the utility model is, a kind of kitten, comprise driving engine, retarder, crawler belt, it is characterized in that: driving engine, retarder are housed in the pentagonal framework, track sprocket on framework, is equipped with the support wheels by bearing fixing under the framework base, track idler is equipped with in the framework neighboring, crawler belt is installed in support wheel, track adjusting wheel, drive wheel periphery, is fixed with control lever and hanger on the framework.
It is the track propulsion tooth of circular arc that described track propulsion wheel periphery has the top.
Described crawler belt comprises two row's crawler belt single-units, has the crawler belt connection shaft to link to each other between single-unit.
Described track idler is divided into front jockey wheel and top guide wheel.
The disclosed kitten of the utility model, crawler belt is in the body periphery, engine speed changer and driving device are installed on the pentagon framework, it is little to have overall volume, but crawler belt is longer, walking is convenient, hill climbing ability is suitable for by force walking on the terraced fields operation in mountain area, hills and mountain stream trail, and crawler belt and soil area of contact are big during operation, is adapted at yielding ground or operation in the farmland of water is arranged.
