Crawler-type fertilizer applicator

Abstract

The invention discloses a crawler-type fertilizer applicator which comprises a fertilizer applicator body, wherein an engine body housing assembly, a cab and a traveling chassis are arranged on the fertilizer applicator body; a power system, an intermediate speed changing box and a hydraulic power system are arranged in the engine body housing assembly; an operating system is arranged in the cab; a fertilizer distribution device is arranged at the front end of the engine body housing assembly; a fertilizer application device is arranged at the rear end of the engine body housing assembly; the fertilizer application device is connected with the engine body housing assembly through a hanger assembly; a hydraulic oil cylinder A is arranged between the fertilizer application device and the hanger assembly; the traveling chassis comprises a traveling wheel system, tensioning wheels and a caterpillar track; a hydraulic oil cylinder B is arranged on the tensioning wheels and is connected with the hydraulic power system. According to the crawler-type fertilizer applicator, the problem of farming delay because of the reduction of the farming efficiency caused by the factor that a walking tractor, which is taken by a conventional fertilizer applicator as a power handpiece, is easy to sink when working in the rainy season or in a paddy field is effectively solved, and the problem that the caterpillar track of an existing crawler-type fertilizer applicator is required to be adjusted manually is also solved.

Description

[0001] technical field [0002] The invention relates to the technical field of agricultural machinery, in particular to a crawler type fertilizer applicator. Background technique [0003] At present, with the continuous in-depth development of China's characteristic agriculture and high-efficiency agriculture, rural labor force transfers to cities, and people's requirements for advanced technology and advanced performance of agricultural machinery continue to increase. Agricultural machinery with small size, high horsepower, simple operation and comfort has become the current agricultural fertilization machinery. The development trend of the existing traditional fertilization machinery usually uses a walking tractor as the power head, but the walking tractor has poor subsidence resistance and can only work in dry fields or hard fields. It will fall into the mud. Although there are crawler fertilizer spreaders on the market, the tension of the crawler of the fertilizer spr...
