[0002] At present, in some small and medium-sized farms with 30 - 50 breeding sows in stock or less than 500 commercial fat pigs sold annually, there is a lack of effective technical guidance in aspects such as breed selection, feeding management, and disease prevention and control. The production level is low, the risk resistance ability is weak, and the breeding efficiency is poor. In order to give full play to the genetic potential of live pigs, ensure the effective supply of the pork market, and promote the income increase of farm households, experts of the National Live Pig Industry Technology System have formulated a series of technical measures to improve the production level of live pigs. During the process of pig raising, cleaning the pigsty is a very important task. Providing a clean and comfortable growth environment for pigs can not only reduce the occurrence of diseases, but also be more conducive to the growth of pigs, which is an important basis for achieving better breeding efficiency.

[0040] As Figure 5 , Figure 6 As shown, the control member 6 includes a control rod 61, a control gear 62, and a long rack 63. The long rack 63 is arranged on the horizontal frame 11. The long rack 63 is arranged in parallel with the lead screw 2. The control rod 61 is rotatably connected to the slider 21. The control gear 62 is coaxially fixedly connected to the end of the control rod 61. When the long rack 63 engages with the control gear 62, the long rack 63 controls the control gear 62 to drive the control rod 61 to rotate.
