[0002] Cat litter is a granular substance used for cats to defecate and urinate. It has good absorbency. In the production process of plant fiber cat litter, a feeding device is often needed to transport the material to the production equipment.

[0003] In the prior art, Chinese utility model with publication number CN218538481U discloses a feeding device for producing plant fiber cat litter. After cooling the material with a condenser pipe, the suction pump and suction pipe work together to generate suction by using negative pressure, which drives airflow to transport the material.

[0031] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 9 The present invention provides a technical solution:

[0033] Example 1: A feeding device for producing plant fiber cat litter, comprising: a feeding square tube 1, an air pump 9, and a cat litter filter plate 6.

[0034] Specifically, multiple sets of equally spaced pusher frames are rotatably installed inside the conveying square tube 1. Each pusher frame includes multiple pusher plates 5 arranged in a circular array. When the pusher frame rotates so that the pusher plates 5 are vertically downward, the pusher plates 5 can push the cat litter material in the lower inner cavity of the conveying square tube 1. A partition 2 is fixedly installed on the upper layer of the air supply interface 11. The partition 2 divides the inner cavity of the conveying square tube 1 into upper and lower layers. The air circulates in the upper and lower inner cavities of the conveying square tube 1, which can cool the cat litter material and extract it. Combined with the rotation of the pusher plates 5, the cat litter material can be effectively conveyed. A clearance groove 3 corresponding to the pusher frame is opened through the surface of the partition 2. The upper part of the pusher frame passes through the clearance groove 3. The clearance groove 3 is designed to prevent the rotation of the pusher plates 5 from being blocked by the partition 2. Baffle plates 4 are fixed on both sides of the clearance groove 3, and the baffle plates 4 cover the outside of the rotation trajectory of the pusher frame. Figure 1 As shown, the baffle plate 4 blocks the upper part of the pusher frame, ensuring that the air in the lower inner cavity of the conveying square tube 1 can still drive the pusher plate 5 to rotate when it flows, thereby providing power for the pusher plate 5 to push the cat litter material to be conveyed.

[0035] Secondly, the air pump 9 is installed at one end of the conveying square tube 1. The air outlet of the air pump 9 is connected to the air supply pipe 10, and the air supply pipe 10 is connected to the air supply interface 11. The air supply interface 11 is fixedly installed on the upper surface of the conveying square tube 1 and communicates with the upper layer of the inner cavity of the conveying square tube 1. The air supply interface 11 is inclined and corresponds to the pusher frame. When the air pump 9 is working, it draws gas from the lower layer of the inner cavity of the conveying square tube 1 and blows the gas into the upper layer of the inner cavity of the conveying square tube 1 along the air supply pipe 10 and the air supply interface 11. Therefore, the air blown into the inner cavity of the conveying square tube 1 through the air supply interface 11 can just drive the pusher plate 5 to rotate, and the air flow drawn by the air pump 9 from the lower inner cavity of the conveying square tube 1 can further drive the pusher plate 5 to rotate, and (as...) Figure 1 (As shown) The direction of rotation of the pusher plate 5 is counterclockwise.

[0036] Furthermore, the cat litter filter plate 6 is fixedly installed in the inner cavity of one end of the conveying square tube 1. A dust filter plate 7 is provided on one side of the cat litter filter plate 6, and a brush plate 8 that fits the surface of the dust filter plate 7 is rotatably installed between the dust filter plate 7 and the cat litter filter plate 6. The cat litter filter plate 6 is used to filter cat litter material, and the dust filter plate 7 is used to filter dust, thereby ensuring that the air drawn into the air pump 9 is cleaner. In addition, the cat litter material and dust can also be separated from each other, thereby improving the quality of the cat litter.

[0037] To reduce the accumulation of cat litter material on the upper part of the pusher rack, the pusher plate 5 of this application is fixedly installed on the surface of the hollow shaft 51. The pusher plate 5 is T-shaped, such as... Figure 5 As shown, the pusher plate 5 is only connected to the hollow shaft 51 in the middle, and there is a gap between the pusher plate 5 and the hollow shaft 51. When the pusher plate 5 rotates and passes the horizontal position, it continues to rotate upward. At this time, the cat litter material remaining on the surface of the pusher plate 5 can slide along the surface of the pusher plate 5 to the gap between the pusher plate 5 and the hollow shaft 51 and fall into this gap, thereby preventing the cat litter material from being thrown onto the upper surface of the partition plate 2 as the pusher plate 5 rotates. A distribution ring 52 is fixedly sleeved in the middle of the surface of the hollow shaft 51. The cross-section of the distribution ring 52 is a hollow triangle. The distribution ring 52 is used to distribute the cat litter on the surface of the pusher plate 5. The material is guided and pushed towards both ends of the pusher plate 5 so that the cat litter material can pass through the gap between the pusher plate 5 and the hollow shaft 51. In addition, a weight-reducing groove is provided on the back of the pusher plate 5. Since the pusher plate 5 of this device always rotates counterclockwise around the hollow shaft 51, the cat litter material is mainly in contact with the front of the pusher plate 5. The front of the pusher plate 5 needs to be kept smooth so that the cat litter material can be separated from the pusher plate 5. The back of the pusher plate 5 has less contact with the cat litter material. By opening the weight-reducing groove, the weight of the entire pusher frame can be reduced, thereby facilitating the rotation of the pusher plate 5 under the action of airflow.

[0038] To facilitate the rotation of the pusher plate 5 driven by air, the material conveying square tube 1 of this application is inclined. The lower end of the partition 2 is provided with a circulation port 21, and a guide plate 22 fixedly connected to the partition 2 is provided on the lower side of the circulation port 21. The guide plate 22 is set in an arc shape. Both the circulation port 21 and the clearance groove 3 can be used to connect the upper and lower layers of the inner cavity of the material conveying square tube 1 to ensure the circulation of air. The setting of the guide plate 22 can guide the air flowing at the location of the circulation port 21, so that the air flows in an arc shape at the end of the material conveying square tube 1, which makes it easier to push the pusher plate 5 to rotate.

[0039] In order to lift and convey cat litter material, this application also has a material trough 13 connected to the other end of the material conveying square tube 1. A discharge port 12 is provided at one end of the lower surface of the material conveying square tube 1. The discharge port 12 is located directly below the cat litter filter plate 6. When this device is in use, the cat litter material is poured into the inner cavity of the material trough 13. The material conveying square tube 1 can lift and convey the cat litter material in the material trough 13 to a certain height. After that, the cat litter material can be discharged from the discharge port 12 under the action of gravity.

[0040] To improve the filtration effect of cat litter, this application also features multiple evenly distributed cat litter filter holes 61 penetrating through the surface of the cat litter filter plate 6, such as... Figure 6 As shown, the cat litter filter holes 61 are relatively narrow, which can filter most cat litter. The cat litter filter holes 61 are semi-circular, which can especially filter and separate long strips of tofu cat litter and prevent them from being blocked by cat litter, thereby improving the filtration effect of cat litter. Multiple small holes are evenly distributed on the surface of the dust filter plate 7. The diameter of the small holes is smaller than the width of the cat litter filter holes 61. The dust filter plate 7 is mainly used to filter and separate dust in cat litter.

[0041] To facilitate cleaning and replacement of the dust filter plate 7, the dust filter plate 7 of this application penetrates the lower surface of the conveying square tube 1 from bottom to top and abuts against the upper inner wall of the conveying square tube 1. A sliding groove is provided on the inner wall of the conveying square tube 1 to guide the sliding of the dust filter plate 7, ensuring that the dust filter plate 7 can only slide up and down in a direction perpendicular to the lower surface of the conveying square tube 1. In other words, after prolonged use, the dust filter plate 7 of this device can be pulled out for cleaning and replacement. A dust collection plate 75 is fixedly installed perpendicular to the lower end of the dust filter plate 7 for dust collection. The upper surface of the plate 75 is provided with a dust collection groove 76, which is connected to the inner cavity of the conveying square tube 1. The dust collection groove 76 can collect dust. The side of the dust collection plate 75 is inclined and is fixedly connected with a magnet 77. The dust collection plate 75 is attracted to the lower surface of the conveying square tube 1 by the magnet 77. The magnet 77 is used to position the dust filter plate 7 as a whole, so as to prevent the dust filter plate 7 from moving easily under the action of gravity. The lower surface of the dust collection plate 75 is fixed with a handle 78, which makes it easy for the staff to pull out the dust filter plate 7.

[0042] For mounting the brush plates 8, multiple brush plates 8 are provided in a circular array. The brush plates 8 are obliquely fixed to the outer wall of the annular cylinder 82, such as... Figure 7 As shown, when air flows along the axial direction of the drive blade 83, the air blows the brush plate 8, which can drive the brush plate 8 and the drive blade 83 to rotate slowly. A rotating shaft is provided at the center of the annular cylinder 82. One end of the rotating shaft is provided with a bearing seat, and the bearing seat is fixed to the inner wall of the conveying square tube 1. The bearing seat is used to limit the brush plate 8, ensuring that the brush plate 8 can rotate in the designated position without deviation. A vertical groove 71 is provided through the middle of the upper half of the dust filter plate 7. A rubber layer 72 is bonded and fixed in the inner cavity of the vertical groove 71. The vertical groove 71 has a notch 73, and the lower end of the vertical groove 71 has a shaft hole 74. The other end of the rotating shaft is movably connected to the shaft hole 74. When the dust filter plate 7 is inserted into the inner cavity of the conveying square tube 1 from bottom to top, the vertical groove 71 can just correspond to the other end of the rotating shaft at the center of the drive blade 83. After the dust filter plate 7 is fully inserted into the inner cavity of the conveying square tube 1, the rotating shaft of the drive blade 83 just passes through the shaft hole 74, thereby avoiding the dust filter plate 7 from obstructing the rotation of the drive blade 83 and the brush plate 8. The rubber layer 72 can prevent dust from passing through the vertical groove 71.

[0043] To clean the surface of the dust filter plate 7, this application also includes a drive blade 83 fixedly arranged between the annular cylinder 82 and the rotating shaft at its center. The drive blade 83 is arranged in a spiral shape. The drive blade 83 is affected by the airflow and can further drive the brush plate 8 to rotate, thereby increasing the torque when the brush plate 8 rotates and avoiding the inability to rotate due to friction. One side of the brush plate 8 is bent and fixedly provided with cleaning bristles 81 perpendicular to the surface of the dust filter plate 7. The cleaning bristles 81 are mainly used to clean the surface of the dust filter plate 7 and prevent the small holes on the surface of the dust filter plate 7 from being blocked by dust.

[0044] To reduce damage to cat litter material, the cross-section of the pusher plate 5 of this application can also be set to an arc shape, which can reduce the accumulation of cat litter material on the surface of the pusher plate 5. A groove 53 is provided at the outer edge of the pusher plate 5, and a flexible pad 54 is bonded and fixed inside the groove 53. Multiple vertical grooves 55 are provided through the surface of the flexible pad 54 at equal intervals. The edge of the flexible pad 54 is attached to the lower inner wall of the conveying square tube 1. The flexible pad 54 itself is soft and can reduce the compression of cat litter material, thereby avoiding damage to the material during the conveying process.
