[0061] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0062] Example 1:

[0063] like Figures 1 to 6 As shown, this utility model provides an auxiliary material adding structure, including: a support frame 1, a stirring structure arranged on the support frame 1 for stirring cat litter material, and a feeding structure arranged on the stirring structure for uniformly adding auxiliary materials into the stirring structure.

[0064] The mixing structure includes a cat litter mixing tank 2 movably mounted on a support frame 1 for storing cat litter materials, a cover plate 201 detachably mounted on the cat litter mixing tank 2 for sealing the cat litter mixing tank 2, a mixing motor 202 arranged above the cover plate 201, a mixing rod 203 arranged on the output end of the mixing motor 202 and located inside the cat litter mixing tank 2, and a multi-stage electric push rod 204 arranged on the support frame 1 for controlling the lifting and lowering of the cover plate 201. The telescopic end of the multi-stage electric push rod 204 is arranged on the cover plate 201. Opening the multi-stage electric push rod 204 can push the cover plate 201 to rise and open the cat litter mixing tank 2, so that cat litter can be poured into it. Then, the cover plate 201 is closed again and the mixing motor 202 is turned on. The mixing motor 202 can control the mixing rod 203 to stir the cat litter materials.

[0065] The feeding structure includes an auxiliary material box 3 arranged above the cover plate 201, a feeding port 301 opened inside the cover plate 201, the feeding port 301 being connected to the auxiliary material box 3, and a feeding component arranged inside the auxiliary material box 3 for controlling the feeding speed. The auxiliary materials to be added are poured into the auxiliary material box 3, and the auxiliary materials can fall into the cat litter in the cat litter mixing bucket 2 through the feeding port 301 for mixing.

[0066] Specifically, the feeding assembly includes an arc-shaped material trough 302 inside the auxiliary material box 3, a connecting shaft 303 rotatably installed inside the auxiliary material box 3, several baffles 304 evenly arranged on the connecting shaft 303, with the corresponding baffles 304 contacting the inner wall of the connecting shaft 303, a feeding motor 305 arranged on one side of the auxiliary material box 3, a first transmission wheel 306 arranged on the output end of the feeding motor 305, a second transmission wheel 307 arranged on one end of the connecting shaft 303, and a transmission belt 308 installed on the first transmission wheel 306 and the second transmission wheel 307. When the feeding motor 305 is turned on, it can drive the first transmission wheel 306 to rotate. The first transmission wheel 306 can drive the connecting shaft 303 to rotate through the transmission belt 308 and the second transmission wheel 307, thereby driving the baffles 304 to move in a circular motion. Under the movement of the baffles 304, the auxiliary material can be carried out of the arc-shaped material trough 302, so that the auxiliary material can fall evenly into the cat litter mixing bucket 2.

[0067] Example 2:

[0068] Based on Example 1, in order to prevent clumps in the auxiliary materials from falling into the cat litter material, a screening structure for separating clumps in the auxiliary materials is arranged on the feeding structure.

[0069] The screening structure includes an L-shaped connecting plate 4 that is slidably installed inside the auxiliary material box 3, and a movable screen plate 401 that is slidably installed on the inner wall of the auxiliary material box 3. The movable screen plate 401 is arranged at one end of the L-shaped connecting plate 4 and located below the arc-shaped material trough 302. The auxiliary material falling from the arc-shaped material trough 302 will fall onto the movable screen plate 401. Auxiliary material of suitable size can fall through the mesh of the movable screen plate 401, while agglomerated auxiliary material will remain on the movable screen plate 401.

[0070] Example 3:

[0071] Based on Example 2, in order to quickly crush the clumps of auxiliary materials so that they can be put back into the cat litter mixing tank 2, a compression structure for crushing clumps is arranged on the feeding structure.

[0072] The extrusion structure includes an extrusion plate 5 slidably installed inside the auxiliary material box 3, a U-shaped guide rod 501 arranged on one side of the extrusion plate 5, a strip-shaped hole 502 opened inside the U-shaped guide rod 501, a linkage shaft 503 arranged on one side of the transmission wheel 307, the linkage shaft 503 being movably installed in the strip-shaped hole 502, an auxiliary pressure plate 504 arranged below the movable screen plate 401 and corresponding to the extrusion plate 5, and a fixed screen plate 505 arranged on the inner wall of the auxiliary material box 3. The elastic component arranged on the L-shaped connecting plate 4 is in contact with the extrusion plate 5 and the auxiliary pressure plate 504. The clumped auxiliary material will fall along the inclined surface of the movable screen plate 401 onto the fixed screen plate 505. Under the continuous rotation of the transmission wheel 307, the U-shaped guide rod 501 can be driven to slide back and forth with the extrusion plate 5, so that the extrusion plate 5 repeatedly presses the clumps against the auxiliary pressure plate 504 to crush the clumps. The clumps crushed to a suitable size can fall into the cat litter mixing tank 2 through the mesh of the fixed screen plate 505.

[0073] Specifically, the elastic component includes a spring 506 arranged on one side of the L-shaped connecting plate 4, a guide rod 507 arranged on one side of the auxiliary material box 3, the L-shaped connecting plate 4 slidably sleeved on the guide rod 507, the spring 506 movably sleeved on the guide rod 507, and a baffle 508 arranged at one end of the guide rod 507 and the spring 506. When the movable screen plate 401 moves, it can drive the L-shaped connecting plate 4 to slide and compress the spring 506. Under the elastic force of the spring 506, the movable screen plate 401 and the auxiliary pressure plate 504 can move adaptively according to the size of the agglomerates.

[0074] The extrusion structure also includes a guide groove 509 inside the U-shaped guide rod 501 and a guide strip 510 arranged on one side of the auxiliary material box 3. The guide strip 510 is slidably installed inside the guide groove 509. When the U-shaped guide rod 501 moves, it can slide on the guide strip 510 through the guide groove 509, thereby limiting the movement direction of the U-shaped guide rod 501 and improving the stability of the U-shaped guide rod 501.

[0075] This utility model also provides a cat litter mixing device, including an auxiliary material addition structure.

[0076] Working principle:

[0077] In use, the multi-stage electric push rod 204 is activated to push the cover plate 201 upward, opening the cat litter mixing bucket 2. Cat litter can then be poured into the cat litter mixing bucket 2. The cover plate 201 is then closed again, and the stirring motor 202 is activated. The stirring motor 202 controls the stirring rod 203 to rotate, thus agitating the cat litter material. Simultaneously, any additional materials that need to be added can be poured into the auxiliary material box 3. The auxiliary materials will fall into the arc-shaped material trough 302 and be blocked by the corresponding baffle plate 304. At this time, the feeding motor 305 is activated. The output end of the feeding motor 305 drives the transmission wheel 306 to rotate. The connecting shaft 303 can be driven to rotate through the transmission belt 308 and the transmission wheel 307. When the connecting shaft 303 rotates, it can drive the baffle plate 304 to move in a circular motion. Under the movement of the baffle plate 304, the auxiliary material can be carried out of the arc-shaped material trough 302 and fall onto the movable screen plate 401. Ordinary auxiliary materials can fall through the mesh of the movable screen plate 401 and finally fall into the cat litter material in the cat litter mixing tank 2 through the feeding port 301. With the continuous movement of the baffle plate 304, the auxiliary material can be continuously conveyed, so that the auxiliary material can fall evenly into the cat litter mixing tank 2 and make it more evenly mixed.

[0078] The movable screen plate 401 is inclined. If there are lumps of auxiliary materials, the lumps will roll down the inclined surface of the movable screen plate 401 towards the auxiliary pressure plate 504, eventually landing on the fixed screen plate 505 and positioned between the extrusion plate 5 and the auxiliary pressure plate 504. The continuous rotation of the transmission wheel 307 drives the linkage shaft 503 to rotate and move within the slotted hole 502, thereby driving the U-shaped guide rod 501 to reciprocate. The reciprocating movement of the U-shaped guide rod 501 causes the extrusion plate 5 to slide back and forth within the auxiliary material box 3, repeatedly pressing the lumps against the auxiliary pressure plate 504 to crush them. Lumps crushed to a suitable size can then pass through the fixed screen plate 505. As the mesh falls into the cat litter mixing tank 2, the auxiliary pressure plate 504 is pushed by the clumps, causing the movable screen plate 401 to slide within the auxiliary material box 3. The movable screen plate 401 then drives the L-shaped connecting plate 4 to slide on the guide rod 507. During this process, the L-shaped connecting plate 4 compresses the spring 506. Under the elastic force of the spring 506, the movable screen plate 401 and the auxiliary pressure plate 504 can move according to the size of the clumps. At the same time, the reciprocating push of the pressure plate 5 causes the movable screen plate 401 to move back and forth, promoting the movement of the auxiliary materials and clumps on the movable screen plate 401, allowing the clumps to quickly slide onto the fixed screen plate 505, thus improving the screening effect.

[0079] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
