Quick-assembly type electric reversing device of agricultural tractor

Abstract

The invention belongs to the technical field of tractor reversing, and particularly relates to a fast-assembly type electric reversing device of an agricultural tractor. Comprising a clutch which is arranged in a tractor body. The clutch comprises a central transmission gear, a rotating shaft, a steering shifting fork and a clutch auxiliary unit. Through triggering of an electric control unit, a first piston presses gas in a first pneumatic cylinder into a first air bag through a first pipeline, the first air bag expands to push a telescopic rod to extend, then a first block is driven to move, and the first block is matched with a rotating ring to enable the telescopic rod to push a steering block to the right side; in the pushing process, the first meshing teeth and the second meshing teeth are separated; similarly, when the steering handle is loosened, the first piston resets under the action of the second spring, gas in the first gas bag is drawn, the telescopic rod is made to contract, then the steering block is further assisted to move leftwards, and combination of the first meshing tooth and the second meshing tooth is achieved.

Description

technical field [0001] The invention belongs to the technical field of tractor reversing, in particular to an electric reversing device of a quick-installation type agricultural tractor. Background technique [0002] Walking tractor is a small tractor, a kind of transportation tool and agricultural machinery popular in Chinese villages and towns. It is powered by diesel engine. Its small, flexible and powerful characteristics make it very popular with farmers; The power of the internal combustion engine passes through the transmission system, and the driving wheel that obtains the driving torque then gives the ground a small, backward horizontal force (tangential force) through the tire pattern and tire surface. This reaction force is the driving force that pushes the tractor forward (also known as bit propulsion). The structure is simple, the power is small, and it is suitable for small arable land. The driver holds the handrail frame to control the operating mechanism, t...

Problems solved by technology

[0003] In the process of using a walking tractor, the steering is inseparable. The steering mechanism of the walking tractor is a jaw clutch, which realizes the steering by cutting off the power of the driving wheel on one side; when driving the walking tractor, pay attention to: When using the jaw-type steering clutch, the separation should be fast and the engagement should be fast. The purpose of this method is to prevent the meshing teeth that transmit power from being half-engaged and half-linked; The edges and corners of the meshing teeth are rounded; when many drivers are driving, especially when turning a small corner, the steering handle is not pinched to the bottom all at once, but only halfway to let the meshing teeth that transmit power produce semi-linkage to complete the steering, which is easy to cause transmission The power meshing teeth wear early, and sometimes the meshing teeth that transmit power will be broken.
