[0030] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 8 , the present invention provides a technical solution:

[0032] Embodiment 1, a bucket elevator for preventing biomass tofu cat litter from piling up, comprises: a housing 1, a rotating shaft 8 and an air duct 9.

[0033] Specifically, a lifting belt 2 is vertically installed in the inner cavity of the shell 1, and a plurality of storage hoppers 3 are installed on the surface of the lifting belt 2 at equal intervals. The storage hopper 3 is a hollow structure with an opening at one end, which is used to temporarily store cat litter. When the lifting belt 2 is driven, the storage hopper 3 moves accordingly, thereby realizing the lifting and transportation of the cat litter. A plurality of evenly distributed filter holes 31 are penetrated at the other end of the storage hopper 3. The pore size of the filter hole 31 is small, and only the crushed cat litter powder can pass through, so as to realize the filtering and separation between the tofu cat litter and the cat litter powder.

[0034] Secondly, the rotating shaft 8 is provided with two transmission wheels 81 fixedly installed on the outer side, and the two transmission wheels 81 are respectively located at the upper and lower ends of the lifting belt 2 and tightened to it. A rotating disk 6 is fixedly installed on both sides of a transmission wheel 81, and a feeding circular hole 61 is opened through the surface of the rotating disk 6, and the feeding circular hole 61 corresponds to the storage hopper 3, such as Figure 3As shown, the turntable 6 rotates synchronously with the rotating shaft 8, and the storage hopper 3 moves synchronously with the transmission of the lifting belt 2. The storage hopper 3 and the turntable 6 have the same angular velocity when rotating. Therefore, after the storage hopper 3 moves to the back of the turntable 6, it can correspond to the feeding circular hole 61, and in the process of rotating 180 degrees, the opening end of the storage hopper 3 and the feeding circular hole 61 always maintain a corresponding state. The external tofu cat litter can pass through the feeding circular hole 61 and enter the inner cavity of the storage hopper 3 for temporary storage. An annular tube 62 is fixedly installed on the surface of a turntable 6, and the annular tube 62 is connected to the inner cavity of the feeding circular hole 61. Figure 6 As shown, the annular tube 62 can connect multiple feeding holes 61 on the surface of a turntable 6. When the air pressure in the inner cavity of the annular tube 62 decreases, external air can pass through the feeding holes 61 and enter the inner cavity of the annular tube 62. The air can drive the tofu cat litter to move during the flow, thereby sucking the tofu cat litter into the inner cavity of the storage hopper 3, and the cat litter powder in the tofu cat litter can pass through the filter hole 31, thereby achieving separation from the tofu cat litter.

[0035] Furthermore, the lower end of the air duct 9 is connected to the annular tube 62, the upper end of the air duct 9 is connected to an exhaust bin 91, and the exhaust bin 91 corresponds to the storage hopper 3 at the highest point. A filter is provided inside the air duct 9. The lower end of the air duct 9 can extract air from the inner cavity of the annular tube 62, so that the external air can suck the cat litter into the inner cavity of the storage hopper 3 when flowing. The upper end of the air duct 9 discharges the air, and the cat litter in the inner cavity of the storage hopper 3 can be blown out at this position. The filter is provided to ensure that the air blown out of the air duct 9 is clean and the cat litter powder will not be blown out.

[0036] In order to connect the inner cavity of the air duct 9 with the inner cavity of the annular tube 62, the present application also has a cavity 82 opened inside the rotating shaft 8, the annular tube 62 and the rotating shaft 8 are concentric, and a connecting tube 63 is fixedly connected between the two, and the two ends of the connecting tube 63 are connected to the inner cavity of the annular tube 62 and the cavity 82 respectively, and the lower end of the air duct 9 is rotatably connected to the rotating shaft 8 through a rotating connector, and the inner cavity of the lower end of the air duct 9 is connected to the inner cavity of the cavity 82. Figure 6 As shown, the lower end of the air duct 9 , the cavity 82 , the connecting pipe 63 and the annular pipe 62 are connected in sequence, and the arrangement of the air duct 9 will not affect the normal rotation of the rotating shaft 8 .

[0037] In order to feed cat litter into the inner cavity of the storage hopper 3, a plurality of feeding circular holes 61 are provided in the present application and are distributed in a circular array around the rotating shaft 8 on the surface of the turntable 6. The plurality of feeding circular holes 61 correspond to the plurality of storage hoppers 3 one by one, respectively. A feeding bin 11 is provided on the outer side of a rotating shaft 8, and the discharge port of the feeding bin 11 corresponds to the feeding circular hole 61 at the lowest point. When the storage hopper 3 moves to the lowest point with the transmission of the lifting belt 2, the cat litter in the inner cavity of the feeding bin 11 can be sucked into the inner cavity of the storage hopper 3 with the flow of air. Then the storage hopper 3 moves up to the highest point, and the cat litter in the inner cavity of the storage hopper 3 is blown out by the air, thereby realizing the lifting of the cat litter. In this process, the cat litter powder in the cat litter is separated from the cat litter, which can avoid the accumulation of cat litter powder and affect the quality of the cat litter.

[0038] In order to seal part of the feeding circular holes 61 during the rotation of the turntable 6, the present application also has a feeding trough 12 installed on the upper end of the surface of the feeding bin 11, and a flexible baffle is provided at the connection between the feeding trough 12 and the feeding bin 11. The feeding trough 12 can be used by the staff to load the inner cavity of the feeding bin 11. The flexible baffle is used to prevent cat litter powder from drifting into the surrounding air, and when the lower end of the air duct 9 draws air, the outside air can pass through the connection between the feeding trough 12 and the feeding bin 11 and then reach the inner cavity of the feeding bin 11. A U-shaped baffle 7 is provided between the feeding bin 11 and another turntable 6, and the U-shaped baffle 7 is in contact with the surface of the turntable 6, the U-shaped baffle 7 is fixedly connected to the shell 1, and the lowest point of the surface of the U-shaped baffle 7 is penetrated by a feeding waist hole 71 connected to the inner cavity of the feeding bin 11. Figure 3 As shown, the U-shaped baffle 7 and the feeding waist hole 71 are used to seal the feeding circular holes 61 at other positions, ensuring that the storage hopper 3 can only be loaded with cat litter when it is at the lowest point.

[0039] In order to prevent the cat litter from falling from the inner cavity of the storage hopper 3 during the lifting process, the present application also has a sealing baffle 5 fixedly installed on the surface of the U-shaped baffle 7, the sealing baffle 5 is in an inverted "U" shape, and the sealing baffle 5 is flush with the surface of another turntable 6, and the sealing baffle 5 fits the opening end surface of the storage hopper 3, such as Figure 3 As shown, when the storage hopper 3 moves to separate from the turntable 6, the sealing baffle 5 can correspond to the storage hopper 3 and is used to seal the open end of the storage hopper 3 to prevent the cat litter in the inner cavity of the storage hopper 3 from falling during the lifting process. A discharge waist hole 51 corresponding to the storage hopper 3 is opened through the highest point of the surface of the sealing baffle 5. When the storage hopper 3 moves to the highest point, the cat litter in the inner cavity of the storage hopper 3 can be discharged through the discharge waist hole 51.

[0040] In order to receive the cat litter discharged from the storage hopper 3, the present application also has a feed frame 10 fixedly mounted on the surface of the sealing baffle 5. The feed frame 10 is tilted and has a side opening 13 corresponding to the discharge waist hole 51. The feed frame 10 is used to receive the cat litter discharged from the storage hopper 3 at the highest point. An arc-shaped guide plate 14 is fixedly mounted in the inner cavity of the feed frame 10, and a rubber pad is bonded and fixed to the surface of the guide plate 14. Since the cat litter is blown out of the inner cavity of the storage hopper 3 by the air discharged from the upper end of the air duct 9, the cat litter has a certain horizontal speed. The guide plate 14 is arranged in conjunction with the rubber pad to buffer and guide the horizontal movement of the cat litter, thereby preventing the cat litter from flying around in the inner cavity of the feed frame 10 due to severe collision.

[0041] In order to drive the lifting belt 2, the present application also has a pulley 83 fixedly connected to the outer side of the end of the rotating shaft 8, and the pulley 83 is driven to rotate by an external belt. The external motor cooperates with the belt to drive the pulley 83 to rotate, thereby driving the transmission of the lifting belt 2 and the rotation of the transmission wheel 81. A fan 92 for driving the air flow in the inner cavity of the air duct 9 is arranged in the middle of the air duct 9. A pressure relief valve is installed on the surface of the air duct 9. The fan 92 drives the air in the inner cavity of the air duct 9 to flow from the lower end of the air duct 9 to the upper end of the air duct 9. The setting of the pressure relief valve can automatically open when the pressure in the inner cavity of the air duct 9 is abnormal, so as to avoid damage to the fan 92 due to excessive load.

[0042] In order to install the storage hopper 3 on the surface of the lifting belt 2, the present application also has a mounting frame 4 arranged on the outer side of the storage hopper 3, to which an annular plate 41 is fixedly connected, and the annular plate 41 is movably sleeved on the outer side of the storage hopper 3, and the mounting frame 4 is fixedly connected to the surface of the lifting belt 2. The mounting frame 4 and the annular plate 41 are arranged to position the storage hopper 3, and the storage hopper 3 can move a certain distance along its own axial direction, so that it can fit more closely with the surface of the turntable 6 and the surface of the sealing baffle 5, thereby preventing the cat litter in the inner cavity of the storage hopper 3 from falling when the storage hopper 3 lifts the cat litter.

[0043] In order to ensure that the opening end of the storage hopper 3 is always in close contact with the surface of the sealing baffle 5 during the lifting process, the present application also has an annular groove 34 in the middle of the surface of the storage hopper 3, and the inner cavity of the annular groove 34 is clamped with a baffle ring 36, and the baffle ring 36 is composed of two semicircular plates spliced ​​and fixed by bolts. Two annular plates 41 are provided, and are respectively located on both sides of the baffle ring 36, such as Figure 3As shown, after the storage hopper 3 is inserted into the inner cavity of the annular plate 41, the retaining ring 36 is installed in the inner cavity of the annular groove 34 on the surface of the storage hopper 3, the retaining ring 36 will be limited by the annular plate 41. At this time, the storage hopper 3 can move a certain distance, but will not be separated from the mounting frame 4. A clamping spring 35 movably sleeved on the outside of the storage hopper 3 is provided between the retaining ring 36 and an annular plate 41. The clamping spring 35 is used to provide thrust to the retaining ring 36, so that the storage hopper 3 always has a tendency to move toward its own open end, so that the open end face of the storage hopper 3 can always be in close contact with the surface of the sealing baffle 5.

[0044] In order to further improve the sealing between the open end of the storage hopper 3 and the sealing baffle 5, the present application also has an annular flange 32 that is folded outward at the open end of the storage hopper 3. A wear-resistant pad 33 is bonded to the surface of the annular flange 32, and the wear-resistant pad 33 is in contact with the surface of the sealing baffle 5. The wear-resistant pad 33 is arranged to improve the sealing between the open end of the storage hopper 3 and the surface of the sealing baffle 5. At the same time, the wear-resistant pad 33 itself has good wear resistance and will not cause the storage hopper 3 to be worn.
