Abstract

The invention discloses a hydraulic screw crawler hiller. A motor part, a speed-change and steering control part, a hilling working mechanism, and a hand-held operation part are arranged on a chassis bracket part of the hiller. The speed-change and steering control part is connected with a crawler travelling part and the hilling working mechanism. In the hilling working mechanism, a left side hilling blade assembly and a right side hilling blade assembly have a same structure, and are symmetrically arranged on two ends of a bracket assembly, relative to a power transmission case which is arranged on the bracket assembly. A left side breadth adjustment mechanism and a right side breadth adjustment mechanism are arranged on the bracket assembly. A left hydraulic driving part and a right hydraulic driving part are connected with the power transmission case. The hilling working mechanism is positioned between two ridges. While screw conveying hilling is carried out, a weeding function is performed. The hilling working mechanism is controlled by a hydraulic pump-motor direct connection system, such that versatility is high. Crawler driving is adopted in the crawler travelling part, such that vehicle trafficability is effectively improved. A working device transmission function is integrated in the speed-change and steering control part, such that the total weight of the hiller can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a hydraulic screw crawler cultivator. Background technique [0002] At present, most of the cultivators are driven by rubber wheels. However, due to the light weight of the cultivator, after entering the field, the ground adhesion is small. When the resistance increases, the driving wheel is easy to slip. When working in the field, the driving rubber wheel is usually changed to an iron driving wheel. The convex teeth of the iron driving wheel in the circumferential direction are inserted into the soil deeply, which can improve adhesion and prevent slipping; but the convex teeth of the iron driving wheel At the same time, it will damage the ditch surface at the bottom of the mud, which is not conducive to the drainage of the field. When walking on the road, due to the large circumferential gap between the convex teeth, the driving wheel contacts the ground in a poly...
