Description

Technical Field

[0001] The present application relates to the field of automation technology, and more specifically, to a double-guide-rod sliding automatic sensing opening device. Background Art

[0002] The animal husbandry industry is a production sector that utilizes the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, fox, mink, otter, and quail, to convert plant energy such as forage and feed into animal energy through artificial breeding and reproduction, in order to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials. In recent years, with the increasing degree of automation in the animal husbandry industry, higher requirements have been placed on equipment accuracy, operational stability, reliability, and degree of automation.

[0003] Automated feeding lines can achieve fully automated operation, reducing worker workload. They automatically transfer feed from the feed tank to the feeding trough. Feeding is time-controlled, with multiple feeding time periods set daily. At the set start time, the three-phase AC motor is powered on, driving the scraper chain and initiating feed feeding. During feeding, a cylinder guide rod is required to control the opening of the feed tank. Traditional single-guide rod sliding opening devices have poor precision, poor stability, and low automation. To address this, we offer a dual-guide rod sliding automatic induction opening device. Summary of the Invention
