Hydraulically-adjusted stone picker

Abstract

The invention discloses a hydraulically-adjusted stone picker. The hydraulically-adjusted stone picker comprises a main frame. A support tube and a traction frame are arranged at the front end of themain frame. The traction frame is connected to a tractor. Soil stop plates are arranged on two sides of the front end of the main frame. Excavating shovels are arranged between the soil stop plates, and a gearbox is arranged above the excavating shovels. The tractor is connected to a universal joint to provide input power of the gearbox. A gear and chain transmission device is connected to the upper end of a gearbox output shaft. A chain driving wheel is connected to the upper end of the gear and chain transmission device. A conveying belt is connected to the upper end of the chain driving wheel. The lower end of the main frame is connected with a hopper lower frame through a plain flange. A hopper, a slide, an oil cylinder pin, a first hydraulic oil cylinder and a second hydraulic oil cylinder are arranged at the upper end of the hopper lower frame. Travelling wheels are arranged at the lower end of the hopper lower frame. The hydraulically-adjusted stone picker has the advantages that processes such as stone picking, stone conveying, stone and soil separating and packaging, and unloading can be completed at a time, manpower is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a hydraulically regulated stone picker. Background technique [0002] In recent years, the area of ​​cultivated land in our country has been continuously decreasing. Due to the large number of rocks in the plateau and mountainous areas, it is difficult to cultivate. At the same time, it will affect the growth of crops and damage the farming machinery. Therefore, it is usually picked up before farming. Stone handling, most of the stone collection boxes in the existing stone picking machines are fixed on the frame, which is not easy to adjust. A small number of stone collection machines can be moved, but because the stone box is too large, it is difficult to unload. Low operating efficiency and other problems, so a stone picking machine controlled by hydraulic pressure is designed. Contents of the invention [0003] The object of the present invention is to provid...
