Hanging cup type planting device driving system based on DC brushless motor

Abstract

The invention discloses a hanging cup type planting device driving system based on a DC brushless motor. A planting device is used for hole punching and seeding planting work in seeding transplanting. The hanging cup planting device based on the DC brushless motor comprises a controller module, a driver module, a storage battery power supply module, the DC brushless motor, a feedback module, a decelerator, a transmission mechanism and a hanging cup transplanting mechanism. The transmission mechanism transmits power and drives a crank rocker mechanism to move, and the put-in pot seeding is carried by a hanging cup when the crank rocker mechanism moves to the highest point; and soil dusting and hole punching are performed by the hanging cup when the crank rocker mechanism moves to the lowest point, and the pot seeding is put in the hole so that seeding planting work is completed. A driving control part is mainly composed of the controller, the DC brushless motor, the driver and the feedback module. The driving system can accurately control movement of the hanging cup via high-precision closed-loop control of motor speed and torque. According to the driving system, the hanging cup can be driven to stably complete planting movement according to the specific movement characteristics so that seeding planting frequency and reliability can be enhanced and short-planting-distance close transplanting work can be realized.

Description

technical field [0001] The invention belongs to the field of motor driving system design, and more specifically relates to a driving system of a hanging cup type planter based on a DC brushless motor. Background technique [0002] With the rapid development of science and technology, crop transplanter technology is constantly developing. The core component of the transplanter is the planter, whose main function is to make holes and plant seedlings, and plant the seedlings sent by the seedling separator or manually into the soil. The design of the planter drive system is one of the key technologies of the transplanter, and it is also one of the difficulties. The hanging cup planter requires a light motor structure and stable performance during the operation process. It requires the drive system to work stably in a harsh working environment, with high speed regulation performance and easy maintenance. [0003] At present, the drive systems of many existing hanging cup plante...
