Control method of dung scraping machine

Abstract

The invention discloses a control method of a dung scraping machine. The dung scraping machine comprises a controller, a motor, a transmission device, corner wheels, a pulling rope and scraping plates, wherein the pulling rope goes around the corner wheels to form a closing structure, limit switches are respectively arranged on two sides of one end of the closing structure and correspond to a stroke zone terminal of the scraping plates on the same side as the limit switches, a buffer zone is formed through extension in the direction from the stroke zone terminal to the end of the closing structure, offside switches are arranged at the terminal of the buffer zone, and trigger signals of the limit switches and the offside switches are accessed to the controller. In the control process of thecontroller, intervention of a time period T<buffer> is protected through the offside switches and buffer, so that protection of the motor and protection of overshooting offside are realized, and thedung scraping machine can work orderly. Through the adoption of the control method disclosed by the invention, the dung scraping process can be effectively and automatically controlled, system facilities are protected, and orderly development of the dung scraping work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding, in particular to a method for controlling a manure scraper. Background technique [0002] With the development of my country's modern animal husbandry, intensive and large-scale pig farms are becoming more and more common, and the amount of excrement produced is concentrated and large. Manual excrement removal requires a huge workload and high labor intensity. The efficiency is low and cannot satisfy the efficient operation of the pig farm. [0003] At present, the automatic control manure scraper system has begun to be popularized and used. The system is placed in the lower layer of the pigsty. After the pig manure falls from the upper layer to the clean layer where the manure scraper system is located, the motor starts at regular intervals under the control of the controller. , drive the traction rope to rotate forward and reverse alternately, so that the dung scraper mov...
