Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a pet food grinder that is easy to clean. Background Technology

[0002] While pet food grinders currently available on the market can meet basic grinding needs, they still have some shortcomings in actual use.

[0003] Most existing pet food grinders only have a single grinding function and cannot perform multi-stage grinding and sieving. During the grinding process, they can only simply grind the food into particles of roughly the same size, which is insufficient to meet the different pets' needs for food fineness. The existing pet food grinders have an unreasonable structural design, with complex and tight connections between the components, making disassembly difficult. During the grinding process, food residue easily adheres to the internal components of the grinder, such as the grinding blades and screens. Because they are difficult to disassemble, these residues cannot be completely removed during cleaning. Long-term accumulation not only affects the grinding effect and lifespan of the grinder, but may also breed bacteria, posing a potential threat to the pet's health. Therefore, we have launched a pet food grinder that is easy to clean. Utility Model Content

[0004] The main purpose of this invention is to provide a pet food grinder that is easy to clean, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pet food grinder that is easy to clean includes a fixed frame, with support feet fixedly connected to the lower end of the fixed frame around its perimeter. A bearing device is fixedly connected to the middle of the inner wall of the fixed frame, and a connecting device is fixedly connected to the upper end of the bearing device. A switch valve is inserted and fixedly connected to the front end of the bearing device, and a feeding pipe is provided on the outer surface of the switch valve.

[0007] The bearing device includes a bearing bucket, a drive motor is fixedly connected to the lower middle part of the bearing bucket, the output end of the drive motor passes through the bearing bucket and is fixedly connected to a docking rotating rod, three slots are opened on the inner wall of the bearing bucket, and mounting lower side plates are fixedly connected to the left and right parts of the outer surface of the bearing bucket, short screws are fixedly connected to the upper ends of the two mounting lower side plates, and fixing bolts are threaded to the outer surfaces of the two short screws, and the bearing bucket is fixedly connected to the middle of the inner wall of the fixing frame.

[0008] Preferably, the connecting device includes a connecting cover plate, with feed inlets at the upper left and upper right ends of the connecting cover plate, and mounting upper side plates fixedly connected to the left and right outer surfaces of the connecting cover plate. Each of the two mounting upper side plates has an insertion hole at its upper end. A grinding assembly is movably connected to the lower end of the connecting cover plate via a bearing. An upper grinding screen plate and a lower grinding screen plate are fixedly connected to the middle and lower outer surfaces of the grinding assembly, respectively. Three locking blocks are fixedly connected to the outer surfaces of both the upper and lower grinding screen plates. The connecting cover plate is tightly attached to the upper end of the carrying barrel.

[0009] By adopting the above technical solution: the connecting cover plate is movably connected to the grinding component through the bearing, so that the grinding component can rotate flexibly under the connecting cover plate without affecting the connection between the connecting cover plate and the bearing barrel, thus ensuring the smooth progress of the grinding process.

[0010] Preferably, the grinding assembly includes a connecting rod, with a rotating shaft block fixedly connected to the middle and lower parts of the outer surface of the connecting rod. Three upper grinding scraper plates are fixedly connected to the outer surface of the upper rotating shaft block, and three lower grinding scraper plates are fixedly connected to the outer surface of the lower rotating shaft block. Limiting sleeves are provided on the middle and lower parts of the outer surface of the connecting rod, and the connecting rod is sleeved on the outer surface of the mating rotating rod.

[0011] By adopting the above technical solution, the connecting rod, as the core connecting component of the grinding assembly, can transmit the power of the drive motor to the entire grinding assembly by being sleeved on the outer surface of the docking rotating rod, so that it can rotate to perform grinding work.

[0012] Preferably, the upper limiting sleeve is located directly below the upper rotating shaft block, the lower limiting sleeve is located directly below the lower rotating shaft block, and the upper end of the connecting rod is connected to the lower middle part of the connecting cover plate via a bearing.

[0013] By adopting the above technical solution, the position setting of the limiting sleeve can accurately limit the position of the rotating shaft block, ensuring that the upper and lower grinding scrapers are in close contact with the corresponding screen plates, thereby improving grinding efficiency and quality.

[0014] Preferably, the bottom of the three upper grinding scrapers is in close contact with the surface of the upper grinding screen plate, and the bottom of the three lower grinding scrapers is in close contact with the surface of the lower grinding screen plate. The three upper grinding scrapers and the three lower grinding scrapers are arranged in an alternating pattern.

[0015] By adopting the above technical solution: the bottom of the grinding scraper is closely attached to the surface of the screen plate, which can fully grind the food on the screen plate during rotation, prevent the food from accumulating on the screen plate, and improve the grinding effect. The upper and lower grinding scrapers are distributed alternately, which can increase the grinding coverage and uniformity, so that the food can be effectively ground at different levels, further improving the grinding quality.

[0016] Preferably, the mesh diameter of the upper grinding screen plate is larger than that of the lower grinding screen plate.

[0017] By adopting the above technical solution, the functions of grading, screening and grinding are achieved. The upper grinding screen plate has larger mesh openings, which first performs preliminary screening of the food, leaving larger particles on the screen plate for further grinding. Smaller particles fall through the upper grinding screen plate into the lower grinding screen plate, which has smaller mesh openings, for further grinding and screening of these particles, ultimately obtaining fine-particle food that meets the requirements, ensuring the fineness and quality of the ground food.

[0018] Preferably, the positional dimensions of the three upper card blocks and the three lower card blocks are adapted to the positional dimensions of the card slot, and the positional dimensions of the two through holes correspond one-to-one with the positional dimensions of the two short screws.

[0019] By adopting the above technical solution, the matching of the card block and the card slot ensures that the grinding component can be accurately installed in the bearing barrel and remain stable during the grinding process, preventing the grinding component from shaking or shifting and affecting the grinding effect.

[0020] Preferably, the carrying bucket has a structure that is wider at the top and narrower at the bottom.

[0021] By adopting the above technical solution, the narrow bottom structure helps to concentrate the collected food at the bottom of the carrying tank, making it easier to discharge through the switch valve and discharge pipe, thus improving unloading efficiency. At the same time, this structure also helps to reduce food residue in the carrying tank and facilitates cleaning.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In this utility model, by setting an upper grinding screen plate and a lower grinding screen plate, along with an upper grinding scraper plate and a lower grinding scraper plate, multi-stage grinding and screening functions are realized. The mesh diameter of the upper grinding screen plate is larger than that of the lower grinding screen plate. After the raw material is poured in, it is first initially ground on the upper grinding screen plate by the upper grinding scraper plate. Larger particles remain on the upper grinding screen plate for further grinding, while smaller particles fall onto the lower grinding screen plate and are further ground and screened by the lower grinding scraper plate. This design can grind food into particles of different fineness, meeting the diverse needs of different pets for food fineness and solving the problem that existing grinders can only perform single grinding.

[0024] 2. In this utility model, the connecting device and the supporting device of the grinder adopt an easy-to-disassemble connection method. The through hole on the upper side plate of the connecting cover corresponds to the position of the short screw on the lower side plate of the supporting barrel, and can be fixed by fixing bolts. At the same time, the locking blocks on the upper and lower grinding screen plates are adapted to the position and size of the locking grooves on the inner wall of the supporting barrel. These designs make it easy to remove the connecting cover and grinding components when cleaning or maintaining the equipment, which can thoroughly remove food residues attached to the internal parts, avoid the problem of residue accumulation affecting the grinding effect and the growth of bacteria, extend the service life of the equipment, and protect the health of pets.

[0025] 3. In this utility model, the stable placement of the equipment through the fixed frame and the support feet around the lower end of the fixed frame ensures the smooth operation of the equipment throughout the grinding process. The mounting lower side plate, short screw, and fixing bolt on the outer surface of the bearing barrel are firmly connected to the connecting device, further enhancing the overall stability of the equipment. Moreover, the upper and lower grinding scrapers are staggered, which reduces vibration and shaking during the grinding process, ensuring the efficient operation of the grinding work. At the same time, it also reduces the wear and tear caused by vibration, improving the reliability and durability of the equipment. Attached Figure Description

[0036] A pet food grinder that is easy to clean includes a fixed frame 1. Support feet 3 are fixedly connected to the lower end of the fixed frame 1. A bearing device 2 is fixedly connected to the middle of the inner wall of the fixed frame 1. A connecting device 4 is fixedly connected to the upper end of the bearing device 2. A switch valve 6 is inserted and fixedly connected to the front end of the bearing device 2. A feed pipe 5 is provided on the outer surface of the switch valve 6.

[0037] In this embodiment, the bearing device 2 includes a bearing bucket 21. A drive motor 27 is fixedly connected to the lower middle part of the bearing bucket 21. The output end of the drive motor 27 passes through the bearing bucket 21 and is fixedly connected to a docking rotating rod 26. Three slots 25 are opened on the inner wall of the bearing bucket 21. The left and right sides of the outer surface of the bearing bucket 21 are fixedly connected to mounting lower side plates 22. The upper ends of the two mounting lower side plates 22 are fixedly connected to short screws 23. The outer surfaces of the two short screws 23 are threaded with fixing bolts 24. The bearing bucket 21 is fixedly connected to the middle of the inner wall of the fixing frame 1. The bearing bucket 21 has a structure that is wider at the top and narrower at the bottom.

[0038] Through the above scheme: the supporting device 2 plays a key role in supporting and driving the pet food grinder. The supporting bucket 21 is fixed in the middle of the inner wall of the fixed frame 1. It has a structure that is wider at the top and narrower at the bottom, which facilitates the collection of ground pet food. When the grinder is started, the drive motor 27 in the middle of the lower end of the supporting bucket 21 starts to work. The output end of the drive motor 27 passes through the supporting bucket 21 and drives the docking rotating rod 26 to rotate. The docking rotating rod 26 provides power for connecting and driving the subsequent grinding components 44. The supporting bucket 21 is stably placed by the fixed frame 1 and the support feet 3 around the lower end of the fixed frame 1, ensuring the smooth operation of the equipment throughout the grinding process. The mounting plate 22, short screw 23, and fixing bolt 24 on the outer surface of the bearing bucket 21 can be used to make a stable connection with the connecting device 4, further enhancing the overall stability of the equipment. The three slots 25 on the inner wall of the bearing bucket 21 are adapted to the locking block 46 in the connecting device 4. This matching design of the slots 25 and the locking block 46 facilitates the installation and disassembly of the grinding component 44, and makes it easy to clean and maintain the equipment. The structure design of the bearing bucket 21, which is wider at the top and narrower at the bottom, is conducive to collecting the ground pet food at the bottom of the bearing bucket 21, which is convenient for subsequent discharge through the switch valve 6 and the discharge pipe 5, thus improving the unloading efficiency.

[0039] In this embodiment, the connecting device 4 includes a connecting cover plate 41. The upper left and upper right portions of the connecting cover plate 41 each have a feed inlet 48. The left and right portions of the outer surface of the connecting cover plate 41 are fixedly connected to mounting upper side plates 42. The upper ends of the two mounting upper side plates 42 each have through holes 43. The lower end of the connecting cover plate 41 is movably connected to a grinding assembly 44 via a bearing. The middle and lower portions of the outer surface of the grinding assembly 44 are respectively fixedly connected to an upper grinding screen plate 45 and a lower grinding screen plate 47. Three locking blocks 46 are fixedly connected to the outer surfaces of both the upper and lower grinding screen plates 45 and 47. The connecting cover plate 41 is tightly attached to the upper end of the carrying barrel 21. The grinding assembly 44 includes a connecting rod 441. The middle and lower portions of the outer surface of the connecting rod 441 are fixedly connected to a rotating shaft block 442. Three upper grinding scraper plates 445 are fixedly connected to the outer surface of the upper rotating shaft block 442, and three upper grinding scraper plates 445 are fixedly connected to the outer surface of the lower rotating shaft block 442. Three lower grinding scraper plates 444 are fixedly connected to the outer surface of block 442. Limiting sleeves 443 are provided at the middle and lower parts of the outer surface of connecting rod 441. Connecting rod 441 is sleeved on the outer surface of docking rotating rod 26. The upper limiting sleeve 443 is located directly below the upper rotating shaft block 442, and the lower limiting sleeve 443 is located directly below the lower rotating shaft block 442. The upper end of connecting rod 441 is connected to the lower middle part of connecting cover plate 41 by a bearing. The three upper grinding scraper plates 445 are connected, with their bottoms tightly attached to the surface of the upper grinding screen plate 45, and the three lower grinding scraper plates 444 are tightly attached to the surface of the lower grinding screen plate 47. The three upper grinding scraper plates 445 and the three lower grinding scraper plates 444 are staggered vertically. The mesh diameter of the upper grinding screen plate 45 is larger than that of the lower grinding screen plate 47. The position dimensions of the two through holes 43 correspond one-to-one with the position dimensions of the two short screws 23.

[0040] Through the above scheme: the connecting device 4 plays an important role in feeding, grinding, and connecting in the pet food grinder. When pet food needs to be ground, the food raw materials are poured in through the feed port 48 on the connecting cover plate 41. After the drive motor 27 is started, its output end drives the docking rotating rod 26 to rotate. Since the connecting rod 441 is sleeved on the outer surface of the docking rotating rod 26, the docking rotating rod 26 will drive the connecting rod 441 to rotate. The rotating shaft block 442 in the middle and lower part of the outer surface of the connecting rod 441 will rotate accordingly. The upper rotating shaft block 442 drives the three upper grinding scraper plates 445 to rotate, and the lower rotating shaft block 442 drives the three lower grinding scraper plates 444 to rotate. The blade plate 445 and the lower grinding scraper plate 444 are staggered vertically. The poured raw material first falls onto the upper grinding screen plate 45. The bottom of the upper grinding scraper plate 445 is in close contact with the surface of the upper grinding screen plate 45, performing preliminary grinding of the raw material. Larger particles remain on the upper grinding screen plate 45 and continue to be ground, while smaller particles fall through the mesh of the upper grinding screen plate 45 into the lower grinding screen plate 47. The bottom of the lower grinding scraper plate 444 is in close contact with the surface of the lower grinding screen plate 47, further grinding the particles screened in the previous step. Since the mesh diameter of the upper grinding screen plate 45 is larger than that of the lower grinding screen plate 47, after being screened by the lower grinding screen plate 47... Fine particles meeting the requirements fall into the bearing tank 21. The connecting cover plate 41 is fitted with the short screw 23 on the lower side plate 22 on the outer surface of the bearing tank 21 through the through hole 43 on the upper side plate 42, and is fixed with the fixing bolt 24, so that the connecting cover plate 41 is tightly attached to the upper end of the bearing tank 21. At the same time, the locking blocks 46 on the outer surface of the upper grinding screen plate 45 and the lower grinding screen plate 47 are adapted to the locking groove 25 on the inner wall of the bearing tank 21, ensuring the stable installation of the grinding assembly 44. The feed port 48 provided on the connecting cover plate 41 facilitates the pouring of pet food raw materials into the grinder, improving the feeding efficiency. The upper grinding screen plate 45 and the lower grinding screen plate 47 fit together well. The same grinding scraper plate realizes multi-stage grinding and screening functions. The upper grinding screen plate 45 initially screens out larger particles, and the lower grinding screen plate 47 further screens out finer particles, ensuring the fineness and quality of the ground food. Through the connection method of installing the upper side plate 42 and the lower side plate 22, and the cooperation of the locking block 46 and the locking groove 25, the connecting device 4 and the bearing device 2 are tightly connected, ensuring the stability of the equipment during the grinding process and reducing vibration and shaking. This connection structure facilitates the disassembly of the connecting device 4. When it is necessary to clean or maintain the equipment, the connecting cover plate 41 and the grinding component 44 can be easily removed, improving the cleaning convenience of the equipment.

[0041] It should be noted that this utility model is a pet food grinder that is easy to clean. During use, the pet food raw materials are first poured in through the feed inlet 48 on the connecting cover plate 41. The drive motor 27 is started, and its output end drives the docking rotating rod 26 to rotate. The docking rotating rod 26 then drives the connecting rod 441 to rotate, causing the grinding assembly 44 to operate. The upper rotating shaft block 442 on the connecting rod 441 drives three upper grinding scraper plates 445, and the lower rotating shaft block 442 drives three lower grinding scraper plates 444 to rotate synchronously. The upper and lower grinding scraper plates 445 and 444 are staggered, grinding the raw materials. During the grinding process, larger particles remain on the upper grinding screen plate 45 for further grinding, while smaller particles fall through the upper grinding screen plate 45 into the lower grinding screen plate. The mesh diameter of the upper grinding screen plate 45 is larger than that of the lower grinding screen plate 47. The lower grinding screen plate 47 further screens the ground food. Fine particles that meet the requirements fall through the lower grinding screen plate 47 and enter the carrying tank 21. The carrying tank 21 has a structure that is wider at the top and narrower at the bottom, which is convenient for collection. When unloading is required, the switch valve 6 is opened and the ground pet food is discharged through the discharge pipe 5. In terms of structural design, the insertion hole 43 on the upper side plate 42 of the connecting cover plate 41 corresponds to the position of the short screw 23 on the lower side plate 22 of the carrying tank 21. It can be fixed by the fixing bolt 24. The locking blocks 46 on the upper grinding screen plate 45 and the lower grinding screen plate 47 are matched with the position and size of the locking groove 25 on the inner wall of the carrying tank 21, which is convenient for installation and disassembly and easy for cleaning.
