[0022] With reference to Figure 1 And Figure 2 In a preferred embodiment, the conveying mechanism includes a U-shaped frame 8 fixed to the top of the feed hopper 2, a rotating shaft 10 rotatably connected to the inner top of the U-shaped frame 8, and an auger 11 fitted with the feed hopper 2 and sleeved on the side wall of the rotating shaft 10. The auger 11 is responsible for gradually conveying the pet food to be screened from the feed hopper 2 to the inside of the box 1. It makes the food evenly enter the screening area through rotation, thereby avoiding the piling up phenomenon caused by pouring too much pet food at one time. A second motor 9 is fixed to the top middle of the U-shaped frame 8, and the output shaft of the second motor 9 is fixed with the rotating shaft 10. Driving the second motor 9 to rotate the rotating shaft 10, in turn drives the auger 11 to rotate, gradually conveying the pet food to the inside of the box 1 and falling into the top of the filter screen 16 for screening. This can avoid the piling up phenomenon caused by pouring too much pet food at one time, prevent affecting the effective screening area of the screen, and improve the screening efficiency.
[0023] With reference to Figure 3 - Figure 5In a preferred implementation, the vibrating mechanism comprises four connecting plates 22, which are arranged at the four corners of the bottom of one of the U-shaped plates 14 and are fixed to the inner side wall of the box 1.

When the spring 24 interacts with the movement of the U-shaped plate 14, it provides elastic support, which means that when the U-shaped plate 14 moves upward, the spring 24 is stretched to store energy, and when the U-shaped plate 14 moves downward, the reaction force of the spring 24 can help it quickly return to its original position, thereby generating a vibrating effect. The outer side wall of the box 1 is fixed with a first motor 3, the output shaft of the first motor 3 is sleeved with a cam 13, and the cam 13 is located below one of the U-shaped plates 14. Driving the two first motors 3 to rotate the two cams 13, when the top of the two cams 13 respectively contacts the two U-shaped plates 14, the two U-shaped plates 14 move upward. At this time, the eight springs 24 gradually become in a stretched state, and each four springs 24 form a group. When the two cams 13 no longer contact the two U-shaped plates 14, the two U-shaped plates 14 are driven to move downward under the reaction of the springs 24 in the stretched state in each group. Since the rotation speed of the two cams 13 is fast, the two U-shaped plates 14 can quickly move up and down, and the two filter screens 16 can vibrate to screen the pet food.
[0024] With reference to Figure 3 and Figure 4In a preferred implementation form, the cleaning mechanism comprises four support plates 15, which are respectively fixed to the top four corners of one of the two U-shaped plates 14, and each of the two support plates 15 is rotationally connected with a same lead screw 17 at the inner side wall thereof, and one end of each of the two lead screws 17 penetrates through the outer side wall of one of the two support plates 15, and the outer side wall of one of the support plates 15 is fixed with a third motor 27, and the output shaft of the third motor 27 is fixed with one of the lead screws 17, and one end of each of the two lead screws 17 is sleeved with a synchronous wheel 20, and the box body 1 is internally provided with a synchronous belt 21, and both ends of the synchronous belt 21 are sleeved on the inner side walls of the two synchronous wheels 20, since the synchronous belt 21 connects the two synchronous wheels 20, the synchronous rotation of the two lead screws 17 is ensured, which helps to ensure the uniform movement of the cleaning brush 19 along the top of the filter screen 16 during the cleaning process, ensures the consistency of the movement, and prevents the phenomenon of one end being stuck, and the side wall of each of the two lead screws 17 is sleeved with a lead screw nut 18, and the two lead screw nuts 18 are respectively matched with the two lead screws 17, and the inner side wall of each of the two lead screw nuts 18 is fixed with a same cleaning brush 19, the third motor 27 drives one of the lead screws 17 to rotate, and the synchronous belt 21 and the two synchronous wheels 20 drive the other lead screw 17 to rotate, and the two lead screws 17 rotate at the same time, and the two lead screw nuts 18 drive the cleaning brush 19 to move along the top of the filter screen 16, and the surface of the filter screen 16 is cleaned, and the mesh holes of the filter screen 16 are prevented from being blocked, and manual cleaning is not required during the process, time is saved, and the work efficiency is improved.
[0025] Referring to Figure 3 and Figure 6 In a preferred implementation form, the outer side wall of the box body 1 away from the first discharge port 4 is provided with a through slot, and the through slot is slidably provided with a collection box 12, and the inner bottom of the box body 1 is fixed with a sliding seat 25 on each side, and the top of each of the two sliding seats 25 is slidably connected with a sliding block 26, and the bottom of each of the two sliding blocks 26 is fixed with the collection box 12, and the pet food that falls into the collection box 12 after two screening processes is unqualified products, and after the screening is completed, the collection box 12 is pulled out from the inside of the box body 1, and the collection box 12 is cleaned.
[0026] The working principle of the present embodiment is: in use, pet food to be sieved is placed in the feeding hopper 2, and the power switch of the second motor 9 is turned on to drive the second motor 9 to rotate the rotating shaft 10, thereby driving the auger 11 to rotate and gradually conveying the pet food into the box body 1 and falling onto the top of the filter screen 16 for sieving. This can avoid the phenomenon of piling up caused by pouring the pet food onto the top of the filter screen 16 at one time, prevent the effective sieving area of the sieve screen from being affected, improve the sieving efficiency, and when sieving, the power switches of the two first motors 3 are turned on to drive the two cams 13 to rotate, respectively, when the two cams 13 are at the top and contact the two back-shaped plates 14, respectively, the two back-shaped plates 14 move upward, at this time, the eight springs 24 are in a gradually stretched state, and each four springs 24 form a group. When the two cams 13 are no longer in contact with the two back-shaped plates 14, the two back-shaped plates 14 are driven to move downward, respectively, under the action of the springs 24 in a stretched state in each group. Since the rotating speed of the two cams 13 is relatively fast, the two back-shaped plates 14 can move up and down quickly, the two filter screens 16 vibrate, and the pet food can be sieved. Since the mesh holes of the two filter screens 16 gradually decrease, pet food of different particle sizes can be sieved and treated. The sieved pet food enters the first guide chute 6 and the second guide chute 7, respectively, through the first discharge port 4 and the second discharge port 5, and is collected. At this time, the pet food falling into the collection box 12 is unqualified product. After sieving, the collection box 12 is pulled out of the box body 1 and cleaned. When the two filter screens 16 need to be cleaned, the power switch of the third motor 27 is turned on to drive the third motor 27 to rotate one of the lead screws 17, and the synchronous belt 21 and the two synchronous pulleys 20 drive the other lead screw 17 to rotate. The two lead screws 17 rotate simultaneously, and the two lead screw nuts 18 drive the cleaning brush 19 to move along the top of the filter screen 16 to clean the surface of the filter screen 16, preventing the mesh holes of the filter screen 16 from being blocked. In the process, manual cleaning is not required, time is saved, and work efficiency is improved.
