Inner deflection swinging cutter blade type ditching cutter head and driving device thereof

Abstract

The invention provides an inner deflection swinging cutter blade type ditching cutter head and a driving device thereof. The inner deflection swinging cutter blade type ditching cutter head comprises a driving box, a driving sprocket, a driving main shaft, a left cutter head device and a right cutter head device, wherein the driving box is arranged on external power equipment, the driving main shaft is arranged on the driving box, the driving box is used for providing power transmission and meanwhile completing the installation and supporting of the other parts, the left cutter head device and the right cutter head device are identical in structure, are arranged at the two sides of the driving box and are respectively arranged on the driving main shaft, the driving sprocket is arranged in the middle of the driving main shaft, and the external power equipment is used for driving the driving sprocket through a chain, so that the driving main shaft is driven to rotate. The inner deflection swinging cutter blade type ditching cutter head is simple in structure, convenient to operate, driven by an eccentric wheel and used for driving a movable cutter blade to deflect so as to realize the variable cross-section soil cutting and has strong practicability; a cutting gearbox is used for blocking part of soil blocks; and the inner deflection swinging cutter blade type ditching cutter head can be used for completely solving the problem that a small-sized self-propelled ditcher cannot be adapted to southland moist clay, and is an ideal machine tool for the ditcher for wooden lands, tea gardens and vegetable gardens.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a combination of an inner deflecting blade type ditching cutter head and a driving device thereof. Background technique [0002] At present, the most widely used trenchers are divided into two types: intermediate drive type and single side drive type according to the driving position, and the single side drive type can be divided into gantry type single side drive and cantilever type single side drive. Usually, the middle drive type is generally applied to small self-propelled ditching machines, such as small forest fruit industry ditching machines, vineyard ditching and fertilizing machines, tea garden ditching and fertilizing machines, etc.; single side drive type is generally used on large tractor-mounted ditching machines. Ditching machine, such as rapeseed shallow tillage ditching machine, chain pipeline ditching machine, etc. The application occasions of the...

Problems solved by technology

However, most of the south of my country is mainly moist and sticky soil. The ditching plow of the ditching machine with the above structure can only push a small amount of soil clods blocked by the transmission to the ditching cutter head, while a large amount of soil clods are accumulated in the transmission. Nearby, the trencher cutter heads are clogged with these clods and cannot continue to operate

In actual operation, it is very difficult for the above-mentioned ditching machine to open a ditch about 1M long in wet and sticky soil.
