Electronic remote control variable speed gear based on green house electric tractor

Abstract

The invention discloses an electronic remote control variable speed gear based on a green house electric tractor, and belongs to the field of greenhouse agricultural machinery. The electronic remote control variable speed gear is characterized in that a signal sent by a remote control signal transmitting device (1) is received by a signal receiving device (2); the signal receiving device (2) is connected with a signal processing device (3) through wires; the signal processing device (3) is connected with a motor controller assembly (4) through the wires; and the motor controller assembly (4) is connected with a direct current series motor (5) through the wires. The electronic remote control variable speed gear based on the green house electric tractor disclosed by the invention is simple in structure, and electronic remote control speed change of the green house electric tractor is realized, the inconvenience and the insecurity of manual speed change of the green house electric tractor and the instability of a conventional mechanical remote control variable speed gear are changed; and the convenience and the stability for the speed change operation of the green house electric tractor are improved, so that the electronic remote control variable speed gear has high popularization and usage values.

Description

technical field [0001] The invention belongs to the field of greenhouse agricultural machinery, in particular to an electronic remote control transmission device based on a greenhouse electric tractor. Background technique [0002] Greenhouse is an important part of agricultural production. Due to its special operating conditions, the development of machinery suitable for greenhouse operations started relatively late. At present, electric tractors suitable for greenhouse operations have been developed in China, but the speed adjustment during operation is mainly manual, which requires the operator to operate randomly in real time, which is labor-intensive, and safety cannot be effectively guaranteed. In response to these problems, domestic scientific research institutes have also carried out relevant research. Chinese patent CN201320190915.4 has announced a remote control transmission device for electric tractors, but because it uses a mechanical remote control transmission ...
