Problems solved by technology
At present, electric tractors suitable for greenhouse operations have been developed in China, but the speed adjustment mainly depends on manual operation, 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 research institutes have also carried out relevant research. Chinese patent CN201320190915.4 has announced a remote control transmission device for electric tractors. The situation where the remote control signal sometimes fails

Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, an electronic remote control transmission device based on a greenhouse electric tractor mainly includes: a remote control signal transmitting device (1), a signal receiving device (2), a signal processing device (3), a motor controller assembly (4), DC series motor (5).
[0013] Such as figure 1 and figure 2 The control schematic diagram of the electronic remote control transmission device is given. The signal sent by the remote control signal transmitting device (1) is received by the signal receiving device (2), and the signal receiving device (2) is connected with the signal processing device (3) through wires, and the signal processing device (3) is connected with the motor controller assembly (4 ) are connected through wires, and the motor controller assembly (4) is connected with the DC series-excited motor (5) through wires...

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 ...
