A drive system of hanging cup type planter based on brushless DC motor

Abstract

The invention discloses a driving system of a hanging cup type planter based on a DC brushless motor. The planter is used for drilling holes and planting seedlings when transplanting seedlings. The hanging cup planter based on the brushless DC motor includes a controller module, a driver module, a battery power supply module, a DC brushless motor, a feedback module, a reducer, a transmission mechanism, and a hanging cup transplanting mechanism. The transmission mechanism transmits power and drives the crank and rocker mechanism to move. When the movement reaches the highest point, the hanging cup accepts the seedlings put in; Seedling work. The drive control part is mainly composed of a controller, a DC brushless motor, a driver and a feedback module. The drive system can accurately control the movement of the hanging cup through high-precision closed-loop control of the motor speed and torque. The drive system disclosed in the present invention can drive The hanging cups follow the specific operating characteristics to complete the planting movement stably, improve the frequency and reliability of seedling throwing, and realize the dense planting and transplanting operations with small plant spacing.

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...
