Description

[0002] Cat litter is an object used by cat owners to bury feces and urine. It has good water absorption. When producing cat litter, a granulator is required to make the cat litter raw materials into a granular structure.

[0003] In the prior art, when cat litter raw materials are granulated by a granulator, an extrusion mechanism is mostly used to extrude the cat litter raw materials so that the cat litter raw materials pass through a granulation template, and then a scraper is driven by a driving mechanism to rotate along one side of the granulation template, thereby scraping off the strip cat litter raw materials passing through the granulation template to form cat litter particles. However, since the cat litter raw materials have a certain viscosity, the scraped cat litter particles are easy to adhere to the current position of the scraper side wall and continue to rotate with the scraper.

[0040] When the cat litter raw material needs to be granulated, the cat litter raw material can be placed in the storage box 10, and then the pressing component 70 is used to press the cat litter raw material, and at the same time, the first driving component 30 is used to drive the plurality of scrapers 40 to rotate in contact with the bottom of the granulation plate 103. When the cat litter raw material is pressed, it can pass through the plurality of rows of granulation holes 104 on the granulation plate 103 and form a plurality of strip structures under the granulation plate 103. The plurality of cat litter raw materials in the strip structure are scraped off by the rotating plurality of scrapers 40, thereby A granular structure is formed. After the cat litter material with a granular structure is scraped off and attached to the side wall of the scraper 40, the second driving assembly 60 drives the transverse scraping assembly 50 to move along the length direction of the scraper 40. The transverse scraping assembly 50 scrapes the cat litter material with a granular structure away from the current position, thereby preventing the cat litter particles from always adhering to the current position of the scraper 40, so that the scraper 40 can smoothly continue to scrape off the strip cat litter material that passes through several rows of granulation holes 104 in the future, thereby improving the granulation effect of the cat litter material.

[0041] See also Figure 1 as well as Figure 6 In one embodiment, the first driving component 30 includes a motor 301 and a rotating shaft 302, wherein the motor 301 is fixedly mounted on the upper portion of the base plate 20, one end of the rotating shaft 302 is connected to the output end of the motor 301, and the other end extends to the bottom center position of the granulation plate 103, and one end of the plurality of scrapers 40 is fixedly connected to the side wall of the rotating shaft 302, and the other end extends along the radial direction of the granulation plate 103.

[0042] After the pressing assembly 70 presses the cat litter raw material through the rows of granulation holes 104, the motor 301 drives the rotating shaft 302 to rotate, thereby driving the scrapers 40 to rotate in contact with the bottom of the granulation plate 103. When the scrapers 40 rotate, the cat litter raw material in a strip structure pressed through the rows of granulation holes 104 is scraped off to achieve granulation of the cat litter raw material.

[0043] See also Figure 3 , Figure 5 as well as Figure 7 In one embodiment, a plurality of arc blocks 105 are fixedly provided on the inner wall of the storage box 10 below the granulation plate 103, and the plurality of arc blocks 105 are distributed in annular intervals on the inner wall of the storage box 10. A slide groove 401 is provided on the side wall of the scraper 40 along the length direction, and a support 403 is fixedly provided on the end of the side wall of the scraper 40 away from the rotating shaft 302. The horizontal scraping assembly 50 includes a scraper 501, a support tube 502 and a first slide bar 503. The scraper 501 is provided with a plurality of groups, and the plurality of scrapers 501 are arranged on one side of the scraper 40 and are distributed in sequence along the length direction of the scraper 40. One end of the plurality of scrapers 501 is in contact with the side wall of the scraper 40, and a group of support tubes 502 is fixedly provided on the other end. A group of support tubes 502 is passed between two adjacent groups of support tubes 502. The connecting rod 504 is fixedly connected, and a group of the first sliding rods 503 are fixedly arranged on the side of each group of the support tubes 502 facing the scraper 40. Several of the first sliding rods 503 extend to the inside of the slide groove 401 away from one end of the corresponding support tube 502 and slide in cooperation with the slide groove 401. The second driving assembly 60 includes a top support rod 601 and a second elastic member 603. One end of the top support rod 601 is fixedly connected to a group of the support tubes 502 farthest from the rotating shaft 302, and the other end passes through the support 403 and movably cooperates with the support 403. A second stop block 602 is fixedly arranged on the side wall of the top support rod 601. One end of the second elastic member 603 is connected to the support 403, and the other end is connected to the second stop block 602, which is used to provide elastic support for the top support rod 601.

[0044] When the motor 301 drives the rotating shaft 302 to rotate and then drives the plurality of scrapers 40 to rotate, the plurality of scrapers 40 can drive the plurality of scrapers 501 and the top support rods 601 to rotate synchronously. When a group of scrapers 40 scrapes off the strip-shaped cat litter material below a row of granulation holes 104, the top support rod 601 on one side of the group of scrapers 40 rotates to the side of a group of arc blocks 105. The group of arc blocks 105 can push the top support rod 601 so that the top support rod 601 moves relative to the corresponding support 403. When the top support rod 601 moves, it can drive the plurality of scrapers 501 to slide against the side wall of the scraper 40 through the plurality of support tubes 502 and the plurality of connecting rods 504. When the scraper 501 slides, it will scrape off the cat litter particles attached to one side of the scraper 40 laterally, so that when the scraper 40 rotates to the position of the next row of granulation holes 104, it can smoothly scrape off the strip cat litter material passing through the next row of granulation holes 104 again; after the scraper 501 scrapes the cat litter particles from the current position of the scraper 40, the top support rod 601 passes through the center position of the current arc block 105. At this time, the second elastic member 603 can push the top support rod 601 to make the top support rod 601 move in the opposite direction of the support 403, thereby driving a plurality of support tubes 502 and a plurality of scrapers 501 to slide in the opposite direction against the side wall of the scraper 40, thereby realizing the resetting of the scraper 501.

[0045] See also Figure 3 as well as Figure 8 In one embodiment, a plurality of arc grooves 402 are provided on the side wall of the scraper 40, a plurality of air holes 509 are provided on the side wall of each group of the support tubes 502, a group of piston rods 508 are movably provided at the bottom of each group of the support tubes 502, a first stopper 507 is fixedly provided on the side wall of the piston rod 508, the first stopper 507 is connected to the support tube 502 through a first elastic member 505, the first elastic member 505 is used to provide elastic support for the piston rod 508, a second slide bar 506 is fixedly provided on the side wall of the first stopper 507, an end of the second slide bar 506 away from the first stopper 507 extends to the inside of the arc groove 402 and slidably cooperates with the arc groove 402.

[0046] When the arc block 105 pushes the top support rod 601 so that the support tubes 502 and the scrapers 501 slide against the side wall of the scraper 40, the support tubes 502 can drive the piston rods 508 to move synchronously. When the piston rod 508 moves, it drives the second slide bar 506 to slide along the corresponding arc groove 402 through the first stopper 507. At this time, the arc groove 402 can push the second slide bar 506 and drive the piston rod 508 to move into the corresponding support tube 502, and then the air inside the support tube 502 is pressed out through the air holes 509. After being pressed out through the air holes 509, the air can act on the cat litter particles scraped by the scraper 501. On the one hand, the air can blow the cat litter particles away from the side wall of the scraper 40 to realize the cat litter particle stripping processing. On the other hand, the air can also have a certain drying effect on the wet cat litter particles, thereby reducing the viscosity between the cat litter particles and the scraper 40, thereby further improving the cat litter particle stripping effect.

[0047] In one embodiment, the first elastic member 505 and the second elastic member 603 may be springs or metal springs, which are not limited herein.

[0048] See also Figure 1 as well as Figure 2 In one embodiment, a feeding pipe 101 is provided on the side wall of the storage box 10 .

[0049] The cat litter material to be granulated is passed from the feed pipe 101 into the storage box 10, and then the pressing assembly 70 inside the storage box 10 is used to apply pressure to the cat litter material, so that the cat litter material passes through the several rows of granulation holes 104 on the granulation plate 103, and then the motor 301 is used to drive the rotating shaft 302 to rotate, thereby driving the several scrapers 40 to rotate, so as to scrape the strip cat litter material passing through the several rows of granulation holes 104, thereby realizing the granulation of the cat litter material.

[0050] See also Fig. 9 In one embodiment, the material pressing assembly 70 includes a hydraulic cylinder 702 and a pressing plate 701 . The hydraulic cylinder 702 is fixedly mounted on the inner top wall of the material storage box 10 , and the pressing plate 701 is arranged at the output end of the hydraulic cylinder 702 .

[0051] The hydraulic cylinder 702 drives the pressing plate 701 to move downward along the inside of the material storage box 10 , thereby pressing the cat litter material so that the cat litter material passes through several rows of granulation holes 104 .

[0052] In the embodiment of the present invention, when it is necessary to granulate the cat litter raw materials, the cat litter raw materials can be placed inside the storage box 10, and then the pressing component 70 is used to apply pressure to the cat litter raw materials. At the same time, the first driving component 30 is used to drive a plurality of scrapers 40 to rotate in contact with the bottom of the granulation plate 103. When the cat litter raw materials are pressed, they can pass through a plurality of rows of granulation holes 104 on the granulation plate 103 and form a plurality of strip structures under the granulation plate 103. The plurality of cat litter raw materials in the strip structure are scraped off by the rotating plurality of scrapers 40 to form a granular structure. After the cat litter raw materials in the granular structure are scraped off and attached to the side wall of the scraper 40, the second driving component 60 is used to drive the cross scraping component 50 to move along the length direction of the scraper 40. The cross scraping The component 50 scrapes the cat litter material with a granular structure away from the current position, thereby preventing the cat litter particles from always adhering to the current position of the scraper 40, so that the scraper 40 can smoothly continue to scrape off the strip cat litter material that passes through several rows of granulation holes 104 in the future, thereby improving the granulation effect of the cat litter material. Compared with the prior art, after the scraper 40 rotates to scrape off the cat litter material passing through the granulation holes 104, the second drive component 60 drives the cross-scraping component 50 to move horizontally along the scraper 40, thereby scraping off the cat litter particles attached to the side wall of the scraper 40 from the current position, so that the scraper 40 can smoothly scrape off the strip cat litter material when it rotates to the position of the next row of granulation holes 104, thereby improving the granulation effect of the cat litter material.
