differential actuator

Abstract

The invention provides a differential execution mechanism. The differential execution mechanism comprises a gearbox body and a control mechanism installed on the gearbox body. The control mechanism comprises a rotating rod and an operation handle, wherein the rotating rod is vertically arranged, the operation handle is transversely connected to the upper end of the rotating rod, the free end of the operation handle is connected with an inhaul cable, a first torsional spring is arranged on the upper portion of the rotating rod in a sleeving mode, one end of the first torsional spring is hooked on the operation handle, the other end of the first torsional spring abuts against a limiting piece arranged on the gearbox body, a connection rod is arranged on the lower portion of the rotating rod, a stirring block is arranged on the connection rod, and the stirring end of the stirring block faces downwards. The differential execution mechanism can be easily used in cooperation with a differential mechanism for achieving the switching between a differential device and a differential lock for two walking wheels of a mini-tiller, the structure is stable, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a differential actuator for switching between a differential and a differential lock of a tiller. Background technique [0002] Tillers are powered by small diesel engines or gasoline engines, and have the characteristics of light weight, small size, and simple structure. Tillers are widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. Equipped with corresponding tools, it can perform operations such as rotary tillage, plowing, sowing, threshing, water pumping, power generation, spraying, spraying, etc. It can also be towed for short-distance transportation. Storage saves the trouble that large agricultural machinery cannot enter mountainous fields. [0003] But at present, one of the biggest problems in the actual operation of agricultural micro-tillers is that the turning function cannot be realized, that is, the differential s...

AI Technical Summary

Problems solved by technology

[0003] However, at present, in the actual operation and use of agricultural tillage machines, one of the biggest problems is that the turning function cannot be realized, that is, the differential speed cannot be realized between the two road wheels.

Because of this defect, the current agricultural micro-tillers cannot effectively cultivate the corner cultivated land in mountainous and hilly areas, and even the angled cultivated land in flat cultivated land can only be realized by the cultivator forcibly dragging the whole machine to realize its steering function. , which greatly increases the labor intensity of the cultivator and reduces the actual cultivated area. The operating mechanism of the existing differential mechanism has a complex structure and is not easy to operate
