Problems solved by technology

[0003] However, it is not easy to solve the problem of fully automatic driving or remote driving of farmland operation machinery
In the field of autonomous driving, the accelerator is relatively easy to control, but it is difficult to achieve gear shifting, steering, braking and other links
Even if it can be realized, it will greatly increase the cost; at present, there are many successful examples of remote control technology applied to tractors, rice transplanters, and harvesters, but these equipments are mainly focused on the structure of existing tractors, rice transplanters, and harvesters. The process of driving the driver is realized by electric or hydraulic system, which has complex structure, high cost and low integration

Abstract

Provided is a device with a remote control gear shifting function. A clutch operation mechanism, a shifting fork gear shifting mechanism, a gear shifting operation mechanism and an automatic control mechanism are integrated, an automatic control hydraulic operation mechanism is adopted as the clutch operation mechanism, two sets of shifting forks are integrated into one gear shifting mechanism through an electric push rod and an electromagnet, and shifting fork shaft section is automatically controlled. Meanwhile, a shifting fork shaft is automatically controlled to move to be engaged and disengaged with a self-locking clutch, and therefore electronic and remote gear shifting is achieved. The device is especially suitable for being applied to the field of low-speed running farmland operation mechanical equipment with a hydraulic source.

Description

technical field [0001] The invention relates to the technical field of crawler equipment power transmission, in particular to a device with a remote control shift function and a control method thereof. Background technique [0002] The running speed of farmland operation machinery is low, such as crawler tractors, crawler-type rotary tillers, harvesters, and rice transplanters, which usually operate at 10Km / h, which is slightly higher than the walking speed of humans; at the same time, the operating conditions of farmland operation machinery are relatively simple. Small changes, for example, after the harvester is aligned with the harvesting row, it goes to the other end of the field without steering, gear shifting, braking, and acceleration and deceleration. Even in the harvesting operation of the entire field, only the steering frequency is high , there is little need to shift gears, brake and add or subtract oil. Moreover, in order to reduce costs, agricultural machinery...
