[0047] It can be seen that the waste gas in the feed production process contains a large amount of dust and is very sticky, and the filter screen 16 for filtering dust needs to be cleaned, such as Figure 4 As shown, under the drive of the motor 31, the rotating rod 321 and the third connecting rod 322 rotate together. At this time, when the third connecting rod 322 rotates toward the first fixed column 33, it pulls the first sliding platform 34 to slide downward on the column 331, and vice versa, it pushes the first sliding platform 34 to slide upward on the column 331. At the same time, during the upward movement of the first sliding platform 34, the fifth connecting rod 341 is pulled, as shown in FIG. Figure 5 As shown, the fifth connecting rod 341 will also pull the pull rod 252 to drive the sliding block 251 to move up in the second sliding groove 25.

[0049] Embodiment 2

[0050] Different from the first embodiment, in order to achieve waste gas deodorization, Figure 4 and 7 As shown, the mixing device 3 includes a motor 31, and a rotating assembly 32 is provided at the output end of the motor 31, and the rotating assembly 32 includes a rotating rod 321, one end of the rotating rod 321 is fixedly connected to the output end of the motor 31, and the other end of the rotating rod 321 is fixedly connected to one end of a No. 3 connecting rod 322, and the other end of the No. 3 connecting rod 322 is rotatably connected to one end of a No. 4 connecting rod 323, and the other end of the No. 4 connecting rod 323 is fixedly connected to a No. 1 sliding platform 34, and one side of the No. 1 sliding platform 34 is rotatably connected to a No. 5 connecting rod 341, and the other end of the No. 5 connecting rod 341 is rotatably connected to one end of a pull rod 252, and a fixed connecting rod 333 is fixedly connected to the bottom of the motor 31, and a No. 1 fixed column 33 is fixedly connected to the bottom of the fixed connecting rod 333, and a No. 1 fixed column 33 is fixedly connected to one end of a plurality of columns 331 at the top of the No. 1 fixed column 33, and a No. 2 fixed column 332 is fixedly connected to the top of the fixed platform 26.

[0051] A ventilation assembly 35 is slidably connected to the column 331, and the ventilation assembly 35 includes a No. 2 sliding platform 351. A plurality of mixing fans 3511 are fixedly connected to the outer wall of the No. 2 sliding platform 351. A No. 1 insertion rod 342 is fixedly connected to the bottom of the No. 1 sliding platform 34.

When the No. 1 sliding platform 34 slides toward the No. 2 sliding platform 351, under the influence of the elastic force of the No. 3 spring 3311 and the No. 4 spring 343, the No. 2 sliding platform 351 will also move together with the No. 1 sliding platform 34, and the No. 3 spring 3311 and the No. 4 spring 343 will first be squeezed and then drive the No. 2 sliding platform 351 to move together. Conversely, the No. 3 spring 3311 and the No. 4 spring 343 will drive the No. 2 sliding platform 351 to move together after being subjected to the pulling force, so the No. 1 sliding platform 34 will There is a time difference in movement with the No. 2 sliding platform 351. When the No. 2 sliding platform 351 moves downward, the swing rod 23 will complete a tilted cleaning filter 16. When the No. 2 sliding platform 351 rebounds and moves upward again, the blocking piece 353 squeezes the medicine feeding pipe 131, and squeezes the mist deodorant to both sides and falls toward the position of the mixing fan 3511. At this time, the mixing fan 3511 blows downward on the side close to the air inlet 11, and the mixing fan 3511 on the other side blows upward to form circulating air above the No. 2 sliding platform 351 for mixed deodorization, and finally flows out from the air outlet 12, so that the exhaust gas circulating in the deodorization chamber 13 can be fully mixed with the deodorant to prevent the problem of insufficient deodorization.
