Problems solved by technology

[0002] Planting vegetables in greenhouses and cultivating pipes in orchards require mechanized equipment. Wheeled tractors are tall behind a person, and agricultural machinery has a long three-point suspension, large turning radius, and strong ground pressure. The operations in greenhouses and orchards are limited, so they cannot meet the requirements. Greenhouse orchard management requirements
[0003] Due to the height restriction when working under the fruit trees, the existing tractors cannot sit on it and can only operate with the car, which is extremely unsafe. Therefore, people need to design a small crawler tractor, but the core of the small crawler tractor is The problem is the gearbox that needs to match it
The existing tractor gearbox cannot realize the power output of positive and negative rotation, and can only be operated manually, and is large in size, poor in reliability, inconvenient to use, and unable to meet various operating needs

Abstract

The invention relates to a small caterpillar tractor transmission case. The small caterpillar tractor transmission case is characterized in that the transmission case further comprises a remote controller, a receiver, an electromagnetic valve and two small one-way oil cylinders, and two one-way valves of the electromagnetic valve are connected with the two small one-way oil cylinders responsible for left steering and right steering through hydraulic oil pipes respectively; and the receiver is connected with the two one-way valves of the electromagnetic valve and a main valve through wires, power of the receiver is supplied by a tractor power supply, and the receiver is used for receiving various instructions sent by the remote controller and enabling the two one-way valves of the electromagnetic valve and the two small one-way oil cylinders responsible for left steering and right steering to work. The transmission case can achieve manual operation and remote-control operation, remote-control operation and manual operation are easy and do not intervene each other, use is convenient and reliable, power output can achieve positive and negative rotation, various operation requirementscan be met, and the transmission case is suitable for various small caterpillar tractors.
