Needle Roller Mulching Machine Control System

Abstract

The invention discloses a control system of a roller needle type mulch punching machine. The control system consists of a control module, a speed setting module, a speed measuring module, a control signal module, a felt roller control module, a needle roller inverter control module and a winding roller inverter control module. At first, the linear speed of mulch is set by the speed setting module for punching, and then punching startup signals are sent by the control signal module. Data of the current linear speed are collected by the control module of the punching machine through the speed measuring module, the current diameter of a winding roller is calculated, the output frequency of an inverter is calculated according to the diameter of the winding roller and the diameter of a needle roller, the calculated output frequency of the inverter is transmitted to the needle roller inverter control module and the winding roller inverter control module, and the working frequency of the inverter is updated promptly. After the working frequency of the needle roller inverter and the winding roller inverter is updated, the actual linear speed is synchronized with the set linear speed, a felt roller is controlled by the felt roller control module to be lifted, and punching can be started.

Description

technical field [0001] The invention relates to a control system for a mulch punching machine, which belongs to the field of agricultural machinery. Background technique [0002] In order to improve the quality and yield of fruits, fruit farmers lay reflective mulch under the fruit trees, and use the reflection of sunlight from the mulch to ensure that the lower fruit of the tree facing the ground can also receive sunlight. However, after the mulch is covered under the tree, there will be three problems. One is that the air permeability of the tree roots is not good; the other is that the rainwater cannot penetrate into the ground in time during and after the rain; In order to solve this problem, it is necessary to punch small holes of reasonable size and spacing on the mulch. The traditional method of punching holes in plastic film is manual punching, and the holes are of different sizes and irregular arrangements, which will affect the lighting effect of the plastic film,...
