Description

Technical Field

[0001] The present application relates to the technical field of material crushing, and in particular to a crushing device for preparing cat litter. Background Art

[0002] Cat is a very common domestic pet. In order to prevent cat litter from randomly defecating indoors, cat litter is used to fix the cat's defecation position to avoid polluting the indoor environment. In the process of making cat litter, raw materials are added to a granulator, and water is continuously added during the operation of the granulator to complete the granulation. After the cat litter is granulated, rod-shaped cat litters of different lengths are formed. The cat litter is screened by a screening machine, and the cat litter with larger volume is removed to ensure that the size and specifications of the final product can be kept consistent. However, during the screening process, some cat litters with larger particles will cause the sieve holes to be blocked, resulting in a reduction in screening efficiency. During granulation, the length of some cat litter particles is too long, resulting in waste during agglomeration, resulting in a reduction in the utilization rate of the cat litter. In this regard, the present application document proposes a crushing device for preparing cat litter, which aims to solve the above-mentioned problems. Summary of the invention

[0003] The present application proposes a crushing device for preparing cat litter, which has the advantages of simultaneously screening and crushing the cat litter, and is used to solve the problem that the utilization rate of the cat litter is reduced due to the excessive length of some cat litter particles.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a crushing device for preparing cat litter, comprising a base, a bracket is fixedly installed on the top of the base near the left side, a receiving bin is fixedly installed on the top of the base near the right side, and a discharge bin is fixedly installed on the top of the bracket. The frosted particles formed by granulation are added into the interior through the top opening of the discharge bin.

[0005] Specifically, a discharge channel is opened on the right side of the discharge bin, and a screening device is fixedly installed at one end of the discharge channel. The cat litter inside the discharge bin slides down under the action of gravity and enters the upper area of ​​the screening device through the discharge channel.

[0006] Specifically, a power device is movably installed at the bottom of the screening device, and a power device is fixedly installed at a position near the right end of the bottom of the screening device, and the power device is movably sleeved with the power device.

[0007] Furthermore, the screening device includes a screening plate, and a mounting tailstock is provided at the bottom of the screening plate near the left end, and the mounting tailstock is fixedly connected to the discharge channel by bolt connection. A sliding trough is provided on the top of the screening plate, and the sliding trough is distributed in an array. Screening holes are provided at the bottom of the sliding trough, and the cat litter will pass through the screening holes and fall into the inside of the receiving bin.

[0008] Specifically, the screening holes are distributed in a linear array along the extension direction of the sliding trough, and baffle plates are fixedly installed on the top of the screening plate near both sides, and the baffle plates can prevent cat litter from overflowing from both sides of the screening plate.

[0009] Furthermore, the screening hole extends from the bottom of the sliding trough to the bottom of the screening plate, and the top opening area of ​​the screening hole is larger than the bottom opening diameter. Both sides of the inner wall of the screening hole are inclined planes, and the front end and the end are semicircular.

[0010] Furthermore, the power device includes a longitudinal beam and a transverse beam, the number of the longitudinal beams is two and they are respectively arranged on both sides of the transverse beam, the two ends of the transverse beam are fixedly connected to the longitudinal beam and the transverse beams are distributed in a linear array along the extension direction of the longitudinal beam, a crushing device is fixedly installed on the top of the transverse beam, a matching hole is opened at the end of the longitudinal beam, the longitudinal beam is movably mounted on the power device through the matching hole, and the power device will drive the longitudinal beam to reciprocate during operation.

[0011] Furthermore, the crushing device includes a mounting bracket, which is fixedly connected to the transverse beam by bolt connection, a baffle is fixedly installed on the top of the mounting bracket, a crushing seat is fixedly installed on the top of the baffle, and the crushing seat is movably installed inside the screening hole.

[0012] Furthermore, the structure of the crushing seat is similar to that of the screening hole, the spacing between the front and rear arc surfaces of the crushing seat is smaller than the spacing between the front and rear arc surfaces of the screening hole, and the inclined planes on both sides of the crushing seat are in contact with the inclined planes on both sides of the screening hole.

[0013] Specifically, the material of the crushing seat is soft rubber. During the reciprocating motion of the crushing seat, the arc parts at both ends of the crushing seat will approach the arc parts at both ends of the inner wall of the screening hole, thereby squeezing the long-grain cat litter into a number of short-grain cat litters.

[0014] Specifically, the outer surface of the baffle is arranged as a curved surface near the top surface, so that the bottom of the long-grain cat litter contacts the curved surface of the outer surface of the baffle when passing through the screening hole and cannot fall.

[0017] The device can screen the cat litter after granulation, and crush the long-grained cat litter during screening, so as to avoid waste caused by agglomeration due to the cat litter being too long. The device can screen and crush at the same time without affecting each other, thereby improving production efficiency. At the same time, the crushed cat litter will not block the screening holes, thus avoiding the problem of blocking the screening holes. In addition, the vibration generated by the eccentric rotation effect of the eccentric wheel can prevent the cat litter from being blocked on the top of the screening plate.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] A crushing device for preparing cat litter, see Figure 1-Figure 3 , including a base 1, a bracket 2 is fixedly installed on the top of the base 1 near the left side, a receiving bin 3 is fixedly installed on the top of the base 1 near the right side, a discharge bin 4 is fixedly installed on the top of the bracket 2, and the frosted particles formed by granulation are added into the inside through the top opening of the discharge bin 4.

[0023] See also Figure 1-Figure 3 A discharge channel 5 is provided on the right side of the discharge bin 4, and a screening device 6 is fixedly installed at one end of the discharge channel 5. The cat litter inside the discharge bin 4 slides down under the action of gravity and enters the upper area of ​​the screening device 6 through the discharge channel 5.

[0024] See also Figure 1-Figure 3 A power device 7 is movably installed at the bottom of the screening device 6, and a power device 8 is fixedly installed at a position near the right end of the bottom of the screening device 6. The power device 8 and the power device 7 are movably sleeved.

[0025] See also Figure 1 and Figure 4-Figure 5 The screening device 6 includes a screening plate 61, and a mounting tailstock 62 is arranged at the bottom of the screening plate 61 near the left end. The mounting tailstock 62 is fixedly connected to the discharge channel 5 by bolt connection. A sliding groove 63 is provided on the top of the screening plate 61, and the sliding groove 63 is distributed in an array. A screening hole 64 is provided at the bottom of the sliding groove 63. The cat litter will pass through the screening hole 64 and fall into the inside of the receiving bin 3.

[0026] See also Figure 4-Figure 5 The screening holes 64 are distributed in a linear array along the extension direction of the slide trough 63 , and baffle plates 65 are fixedly installed on the top of the screening plate 61 near both sides, and the baffle plates 65 can prevent cat litter from overflowing from both sides of the screening plate 61 .

[0027] See also Figure 4-Figure 5 The screening hole 64 extends from the bottom of the sliding trough 63 to the bottom of the screening plate 61, and the top opening area of ​​the screening hole 64 is larger than the bottom opening diameter. The inner walls of the screening hole 64 are inclined planes on both sides, and the front end and the end are semicircular.

[0028] See also Figure 6 and Figure 8The power device 7 includes a longitudinal beam 71 and a transverse beam 72. There are two longitudinal beams 71 and they are respectively arranged on both sides of the transverse beam 72. Both ends of the transverse beam 72 are fixedly connected to the longitudinal beam 71 and the transverse beams 72 are distributed in a linear array along the extension direction of the longitudinal beam 71. A crushing device 73 is fixedly installed on the top of the transverse beam 72. A matching hole 74 is opened at the end of the longitudinal beam 71. The longitudinal beam 71 is movably mounted on the power device 8 through the matching hole 74. During operation, the power device 8 will drive the longitudinal beam 71 to reciprocate through the power device 8.

[0029] See also Figure 5 and Figure 7 The crushing device 73 includes a mounting bracket 731, which is fixedly connected to the transverse beam 72 by bolt connection. A baffle 732 is fixedly installed on the top of the mounting bracket 731, and a crushing seat 733 is fixedly installed on the top of the baffle 732. The crushing seat 733 is movably installed inside the screening hole 64.

[0030] See also Figure 5 and Figure 7 The structure of the crushing seat 733 is similar to that of the screening hole 64 , the spacing between the front and rear arc surfaces of the crushing seat 733 is smaller than the spacing between the front and rear arc surfaces of the screening hole 64 , and the inclined planes on both sides of the crushing seat 733 are in contact with the inclined planes on both sides of the screening hole 64 .

[0031] The front and rear ends of the crushing seat 733 and the front and rear ends of the inner wall of the screening hole 64 are designed as arc surfaces, and the outer surface of the baffle 732 is set to an arc shape, which allows short-grained cat litter to better pass through the gap between the crushing seat 733 and the screening hole 64. At the same time, long-grained cat litter will remain in the gap between the crushing seat 733 and the screening hole 64 regardless of the posture in which it enters, thereby ensuring the crushing effect of the device.

[0032] See also Figure 5 and Figure 7 The material of the crushing seat 733 is soft rubber. During the reciprocating motion of the crushing seat 733, the arc parts at both ends of the crushing seat 733 will approach the arc parts at both ends of the inner wall of the screening hole 64, thereby squeezing the long-grain cat litter into a number of short-grain cat litters.

[0033] See also Figure 5 and Figure 7 The crushing seat 733 is made of soft rubber, so that when the crushing seat 733 and the screening hole 64 squeeze the long-grain cat litter, they will only divide the long-grain cat litter into multiple sections, and will not squeeze the cat litter into powder, thereby improving the stability of the device during operation.

[0034] When the cat litter slides into the interior of the sliding trough 63, the short-grained cat litter passes through the gap between the crushing seat 733 and the screening hole 64 and falls into the interior of the receiving bin 3, while the long-grained cat litter will contact the curved surface structure on the outside of the baffle 732 at the bottom during the process of passing through the gap between the crushing seat 733 and the screening hole 64. Since the upper part of the long-grained cat litter is still in the gap between the crushing seat 733 and the screening hole 64 at this time, the long-grained cat litter cannot fall, and in the process of the reciprocating motion of the power device 7, the crushing seat 733 will squeeze the long-grained cat litter remaining in the gap, causing it to break and form multiple segments of short-grained cat litter, thereby completing the crushing of the long-grained cat litter, avoiding the situation where some cat litters are too long after granulation and cause waste when agglomerating, thereby providing practicality of the device.

[0035] During the reciprocating motion of the power device 7, when the crushing seat 733 moves forward, the curved surface at the front end of the crushing seat 733 will be close to the curved surface at the front end of the inner wall of the screening hole 64 and crush and squeeze the cat litter. At the same time, the curved surface at the rear end of the crushing seat 733 and the curved surface at the rear end of the inner wall of the screening hole 64 still maintain a certain distance, and the cat litter can still be screened, ensuring that the device can continue the screening operation normally while crushing the cat litter, avoiding the device from being unable to screen the cat litter normally due to crushing, thereby improving the reliability of the device.

[0036] See also Figure 5 and Figure 7 The outer surface of the baffle 732 is arranged to be an arc surface near the top surface, so that the bottom of the long-grain cat litter contacts the arc surface of the outer surface of the baffle 732 when passing through the screening hole 64 and cannot fall.

[0037] See also Figure 6 and Fig. 9 The power device 8 includes a power machine 81, and eccentric wheels 82 are fixedly installed at both ends of the output shaft of the power machine 81. A connecting sleeve 83 is movably sleeved on the front side of the eccentric wheel 82 near the outer side. An elastic telescopic rod 84 is fixedly installed on one end of the connecting sleeve 83, and the front end of the elastic telescopic rod 84 is movably sleeved with the matching hole 74.

[0038] When the power machine 81 drives the eccentric wheel 82 to rotate, and in the process of driving the power device 7 to perform reciprocating motion as a whole, it will also produce a vibration effect on the screen plate 61. Under this effect, the cat litter on the top of the screen plate 61 will continue to slide down under the action of the vibration, thereby avoiding the problem of cat litter accumulating on the top of the screen plate 61 and causing blockage, thereby improving the stability of the device.

[0039] The method of use of the present invention is as follows: During use, the cat litter formed by granulation is added to the inside of the discharge bin 4 through the top of the discharge bin 4, and under the action of gravity, the cat litter slides into the top of the screening plate 61 through the discharge channel 5 and enters the inside of the sliding trough 63. When the cat litter slides into the inside of the sliding trough 63, the short-grained cat litter passes through the gap between the crushing seat 733 and the screening hole 64 and falls into the inside of the receiving bin 3, and the long-grained cat litter will contact the curved surface structure on the outside of the baffle 732 when passing through the gap between the crushing seat 733 and the screening hole 64. Since the upper part of the long-grained cat litter is still in the gap between the crushing seat 733 and the screening hole 64 at this time, the long-grained cat litter cannot fall, and in the process of reciprocating motion of the power device 7, the crushing seat 733 will squeeze the long-grained cat litter remaining in the gap, causing it to break and form multiple sections of short-grained cat litter, thereby completing the crushing of the long-grained cat litter. The cat litter is crushed, and during the reciprocating motion of the power device 7, when the crushing seat 733 moves forward, the front end arc surface of the crushing seat 733 will be close to the arc surface of the front end of the inner wall of the screening hole 64 and crush and squeeze the cat litter. At the same time, the rear end arc surface of the crushing seat 733 and the arc surface of the rear end of the inner wall of the screening hole 64 still maintain a certain distance, and the cat litter can still be screened, ensuring that the device can continue to screen the cat litter while crushing the cat litter. When the crushing seat 733 and the screening hole 64 squeeze the long-grain cat litter, they will only divide the long-grain cat litter into multiple sections, and will not squeeze the cat litter into powder. When the power machine 81 drives the eccentric wheel 82 to rotate, while driving the power device 7 to reciprocate as a whole, it will also produce a vibration effect on the screening plate 61. Under this action, the cat litter on the top of the screening plate 61 will continue to slide down under the action of vibration.
