A support plate is symmetrically arranged between the two support springs. The tops of the two support plates are in contact with the lower surface of the guiding inclined plate. The bottoms of the two support plates are fixedly connected to the inner bottom wall of the blanking box by screws. Fixed plates are welded on both sides of the long side of the lower surface of the blanking box. Guide rods are arranged at the turning points of the two pull ropes. The two ends of the two guide rods are rotatably connected to the plate surface of the fixed plate.

[0009] Specifically, in this technical solution, a protective shell is installed on the side of the shielding block away from the moving plate by screws. The control component is arranged in the protective shell. An inner channel tooth is arranged on the side of the moving plate facing the chute wall. An installation groove is formed at the top of the shielding block, and a groove is formed on one side wall of the installation groove.

[0010] Specifically, in this technical solution, the control component includes a driving gear located in the installation groove. The tooth surface of the driving gear is meshed and connected with the inner channel tooth. A rotating shaft is fixedly penetrated through the center of the driving gear. The two ends of the rotating shaft are respectively rotatably connected to the wall of the installation groove and the groove. A first bevel gear is fixedly sleeved on the outer wall of the rotating shaft in the groove. A second bevel gear is meshed and connected to one side tooth surface of the first bevel gear. A shaft rod is fixedly penetrated through the center of the second bevel gear; A positive and negative motor is installed on the inner wall of the protective shell by screws.

One end of the shaft rod penetrates through the shielding block and is rotatably connected to the inner wall of the protective shell. The worm gear is fixedly sleeved on the shaft rod.

[0011] Specifically, in this technical solution, the length and height of the shielding block are both matched with the length and height of the hot air pipe. The height of the air volume control box is greater than the height of the hot air pipe. The inner box walls of the air volume control box are in contact with the outer walls of the shielding block and the protective shell. An insulating layer is arranged in the shell wall of the protective shell.

[0012] Specifically, for this technical solution, a driving motor is installed on one side of the bottom wall of the drying oven through screws. The output end of the driving motor is connected to a coupling. The top end of the coupling is connected to a vertical shaft, and the top end of the vertical shaft penetrates through the bottom wall of the drying oven and is fixedly screwed to the lower surface of the centrifugal disc.

[0014] According to the above technical solution, a production process for a cat litter drying device with adjustable moisture control will also be provided, including the following steps: Step 1: Cat litter feeding. The produced cat litter falls onto the guiding inclined plate through the port of the feeding box. Under the action of gravity, the guiding inclined plate is pressed down, so that the cat litter falls onto the conveyor belt and is transported to the centrifugal disc. The driving motor works to control the rotation of the vertical shaft through the coupling, so that the centrifugal disc rotates. Step 2: Air intake control. When the guiding inclined plate moves downward, it will squeeze the supporting spring and move the pull rope. The movement of the pull rope will cause the shielding block to move downward along the inner wall of the air volume control box, and the nozzle of the hot air pipe is completely exposed, and the air intake is adjusted in real time following the weight of the feeding. Step 3: Moisture drying. The falling cat litter falls from all around onto the lower dispersing plate under the centrifugal action of the centrifugal disc, and falls onto the sieve along the hypotenuse under gravity. The bent rod will move along the surface of the dispersing plate following the rotation of the vertical shaft to stir the cat litter, and cooperate with the hot air entering from the hot air pipe to accelerate the drying speed. The dried cat litter falls to the bottom of the box through the mesh holes of the sieve and is discharged from the discharge pipe.

Control the moving plate to move upward along the chute through the inner track teeth to partially block the hot air pipe and control the air intake.

[0016] In summary, the present invention mainly has the following beneficial effects: In this application, the cat litter falls from the port of the feeding box onto the guiding inclined plate, and as the amount of the falling cat litter increases, it moves downward under the action of its own weight. The moving guiding inclined plate squeezes the supporting spring, and the baffle block is controlled by a pulling rope to move downward along the inner wall of the air volume control box at the same time. The cat litter will fall onto the conveyor belt and be transported into the drying box, and then fall above the rotating throwing disc. Under the action of centrifugal force, it falls from all around onto the dispersing plate and moves along the plate surface to fall onto the screen. The heated gas enters the drying box through the hot air pipe to dry the cat litter, so that the air intake volume can be automatically adjusted according to the weight of the fed cat litter without manual intervention, improving the operation convenience and automation degree; Meanwhile, when automatically adjusting the air intake volume, the forward and reverse motor can be started according to requirements. Under the drive of the worm and gear and the bevel gear, the driving gear is controlled to rotate, and under the action of the inner channel teeth, the moving plate is controlled to move to block the hot air pipe, so that the air intake volume can be separately controlled as needed to achieve flexible adjustment and adapt to different drying conditions.

An air volume control box 1021 is connected to the hot air duct 102. A driving motor 2013 is installed on one side of the bottom wall of the drying box 1 by screws. The output end of the driving motor 2013 is connected to a coupling 2012. The top end of the coupling 2012 is connected to a vertical shaft 201. The top end of the vertical shaft 201 penetrates the bottom wall of the drying box 1 and is fixedly screwed to the lower surface of the throwing disc 2. A funnel-shaped dispersing plate 202 is arranged below the throwing disc 2. A screen 203 is arranged below the dispersing plate 202. Curved rods 2011 are arranged on the upper surface of the dispersing plate 202. The curved rods 2011 are fixedly screwed to the outer wall of the vertical shaft 201. The outer walls of the dispersing plate 202 and the screen 203 are fixedly connected to the inner wall of the drying box 1. The air inlet of the hot air duct 102 is located above the screen 203. An outlet pipe 101 is connected to the bottom of the outer wall of the drying box 1 away from the hot air duct 102; The adjusting mechanism 4 consists of an adjusting component 5, a shielding block 6, and a control component 7. The shielding block 6 is slidably installed in the air volume control box 1021. The adjusting component 5 connects the guiding inclined plate 301 and the shielding block 6. The adjusting component 5 is used to automatically adjust the air intake according to the incoming cat litter. A sliding groove 601 is formed on one side of the shielding block 6. A moving plate 602 is slidably arranged in the sliding groove 601. The control component 7 is used to adjust the height of the moving plate 602; On one side of the shielding block 6 away from the moving plate 602, a protective shell 603 is installed by screws. The control assembly 7 is arranged in the protective shell 603. On one side of the moving plate 602 located on the groove wall of the sliding groove 601, an inner toothed track 6021 is provided. An installation groove 604 is formed at the top of the shielding block 6. A groove 6041 is formed on one side wall of the installation groove 604. The length and height of the shielding block 6 are both matched with the length and height of the hot air pipe 102. The height of the air volume control box 1021 is greater than the height of the hot air pipe 102. The inner box walls of the air volume control box 1021 are in contact with the outer wall of the shielding block 6 and the protective shell 603. An insulating layer is provided inside the wall of the protective shell 603.

[0023] When drying the moisture of the produced cat litter, the cat litter is fed into the feeding box 3 from the port of the feeding box 3 through the conveying device. With the increase of the falling cat litter, under the action of gravity, the guiding inclined plate 301 moves downward. During the downward movement, the shielding block 6 is controlled to move downward along the air volume control box 1021 through the adjusting assembly 5, so that the pipe orifice of the hot air pipe 102 is exposed. The heated hot air enters the drying box 1, and the cat litter will fall onto the conveyor belt 302 along the plate surface of the guiding inclined plate 301. The conveyor belt 302 transports the cat litter to the drying box 1 and falls onto the throwing disc 2. At the same time, the driving motor 2013 works. The output end of the driving motor 2013 controls the vertical shaft 201 to rotate through the coupling 2012. The vertical shaft 201 drives the throwing disc 2 and the bent rod 2011 to rotate. Under the centrifugal action of the throwing disc 2, the cat litter falls from all around to the lower dispersing plate 202 and moves along the plate surface to the lower screen 203. During the falling process, the contact area between the cat litter and the hot air can be increased. The rotating bent rod 2011 will stir the cat litter on the plate surface of the dispersing plate 202, increase the falling speed and prevent the cat litter from sticking to the plate surface. The dried cat litter falls to the bottom wall of the drying box 1 through the mesh holes of the screen 203 and is discharged from the discharge pipe 101. Thus, the air intake volume can be automatically adjusted according to the weight of the incoming cat litter without manual intervention, improving the operation convenience and automation degree.

[0024] Please refer to Figures 2-4As shown in the figure, the adjustment component 5 includes two support springs 502 arranged below the guiding inclined plate 301. The top ends of the two support springs 502 are in contact with the lower surface of the guiding inclined plate 301. On both sides of the lower surface of the guiding inclined plate 301, stay ropes 503 are symmetrically connected. The other ends of the two stay ropes 503 are connected to the upper surface of the shielding block 6. The two stay ropes 503 are arranged in a Z shape. The bottom ends of the two support springs 502 are fixedly connected to the inner bottom wall of the blanking box 3. Between the two support springs 502, support plates 501 are symmetrically arranged. The top ends of the two support plates 501 are in contact with the lower surface of the guiding inclined plate 301. The bottom ends of the two support plates 501 are fixedly screwed to the inner bottom wall of the blanking box 3. On both sides of the long side of the lower surface of the blanking box 3, fixing plates 504 are welded. At the turning points of the two stay ropes 503, guide rods 505 are arranged. The two ends of the two guide rods 505 are rotatably connected to the plate surface of the fixing plate 504.

[0025] When the guiding inclined plate 301 moves downward following the amount of the cat litter being discharged, it will squeeze the support springs 502 and drive the stay ropes 503 to move. The moving stay ropes 503 control the movement of the shielding block 6 in the air volume control box 1021 along the two guide rods 505. Among them, under the action of the support plates 501, the downward movement distance of the guiding inclined plate 301 can be ensured. When the discharge of the cat litter decreases, the elasticity of the support springs 502 will push the guiding inclined plate 301 upward. The upward moving guiding inclined plate 301 will drive the shielding block 6 to move upward by pulling the stay ropes 503, and will block the pipe orifice of the hot air pipe 102 to a certain extent. Furthermore, by connecting the shielding block 6 and the guiding inclined plate 301, the change in the feeding amount can be responded to in a timely manner, and the air intake volume can be changed.

[0026] Please refer to Figures 3-6 As shown in the figure, the control component 7 includes a driving gear 701 located in the installation groove 604. The tooth surface of the driving gear 701 is meshed and connected with the inner ring teeth 6021. A rotating shaft 702 is fixedly penetrated through the center of the driving gear 701. The two ends of the rotating shaft 702 are respectively rotatably connected to the groove walls of the installation groove 604 and the groove 6041. On the outer wall of the rotating shaft 702 located in the groove 6041, a first bevel gear 703 is fixedly sleeved. On one side tooth surface of the first bevel gear 703, a second bevel gear 704 is meshed and connected. A shaft rod 7041 is fixedly penetrated through the center of the second bevel gear 704. On the inner wall of the protective shell 603, a positive and negative motor 707 is installed by screws. The output end of the positive and negative motor 707 is connected with a worm 706 through a flange. Above the worm 706, a worm gear 705 is meshed and connected. One end of the shaft rod 7041 penetrates through the block body of the shielding block 6 and is rotatably connected to the inner wall of the protective shell 603. The worm gear 705 is fixedly sleeved on the shaft rod 7041. Among them, in order to dissipate heat from the positive and negative motor 707, a telescopic pipe can be connected to the bottom of the protective shell 603 and penetrate through the bottom of the air volume control box 1021 and extend to the outside for heat dissipation.

[0027] When the feeding amount of the cat litter remains unchanged and the air intake needs to be adjusted separately, the forward and reverse motor 707 is started by the controller. The output end of the forward and reverse motor 707 drives the worm 706 to rotate. The worm 706 drives the engaged worm wheel 705 to rotate. The rotational force is transmitted to the second bevel gear 704 through the inserted shaft rod 7041. The second bevel gear 704 drives the engaged first bevel gear 703 to rotate. The first bevel gear 703 transmits the rotational force to the driving gear 701 through the inserted rotating shaft 702. The rotation of the driving gear 701 is controlled by the inner track teeth 6021 to move the moving plate 602 along the chute 601. The moving plate 602 separately blocks the nozzle of the hot air pipe 102, and the air intake can be separately controlled as needed, achieving flexible adjustment to adapt to different drying conditions and regulating the moisture control.

[0028] Please refer to Figures 1-7 As shown, according to the above embodiments, a production process of a cat litter drying device with adjustable moisture control will also be provided, including the following steps: Step 1: Cat litter feeding. The produced cat litter falls onto the guiding inclined plate 301 through the port of the feeding box 3. Under the action of gravity, the guiding inclined plate 301 is pressed down, so that the cat litter falls onto the conveyor belt 302 and is transported to the throwing disc 2. The driving motor 2013 works to control the rotation of the vertical shaft 201 through the coupling 2012, so that the throwing disc 2 rotates; Step 2: Air intake control. When the guiding inclined plate 301 moves downward, it will squeeze the supporting spring 502 and move the pulling rope 503. The movement of the pulling rope 503 will cause the blocking block 6 to move downward along the inner wall of the air volume control box 1021, and the nozzle of the hot air pipe 102 is completely exposed, and the air intake is adjusted in real time following the weight of the feeding; Step 3: Moisture drying. The falling cat litter falls from all around onto the lower dispersion plate 202 under the centrifugal action of the throwing disc 2, and falls onto the screen 203 along the hypotenuse under gravity. The curved rod 2011 will move along the surface of the dispersion plate 202 following the rotation of the vertical shaft 201 to stir the cat litter, and cooperate with the hot air entering from the hot air pipe 102 to accelerate the drying speed. The dried cat litter falls to the bottom of the box through the mesh holes of the screen 203 and is discharged from the discharge pipe 101; In step 2, when the air intake needs to be adjusted separately, the forward and reverse motor 707 is started. The rotational force is transmitted to the second bevel gear 704 through the worm 706 and the worm wheel 705, driving the first bevel gear 703 to rotate, and driving the driving gear 701 to rotate. The inner track teeth 6021 are used to control the moving plate 602 to move upward along the chute 601 to partially block the hot air pipe 102 to control the air intake.

[0029] The working principle of the present invention is: When drying the moisture of the produced cat litter, the cat litter is fed into the blanking box 3 through the transport device from the port of the blanking box 3. As the amount of the falling cat litter increases, under the action of gravity, the guiding inclined plate 301 moves downward. When the guiding inclined plate 301 moves downward following the amount of the fed cat litter, it will squeeze the supporting spring 502 and drive the pulling rope 503 to move. The moving pulling rope 503 controls the movement of the shielding block 6 in the air volume control box 1021 along the two guiding rods 505; When the feeding amount of the cat litter decreases, the elasticity of the supporting spring 502 will push the guiding inclined plate 301 upward. The upward moving guiding inclined plate 301 will drive the shielding block 6 to move upward by pulling the pulling rope 503, and will block the nozzle of the hot air pipe 102 to a certain extent to change the air intake volume; And the cat litter will fall onto the conveyor belt 302 along the plate surface of the guiding inclined plate 301. The conveyor belt 302 transports the cat litter to the drying box 1 and falls onto the throwing disc 2. At the same time, the driving motor 2013 works. The output end of the driving motor 2013 controls the vertical shaft 201 to rotate through the coupling 2012. The vertical shaft 201 drives the throwing disc 2 and the bent rod 2011 to rotate. Under the centrifugal action of the throwing disc 2, the cat litter falls from all around to the dispersing plate 202 below and moves along the plate surface to the sieve 203 below. During the falling process, the contact area between the cat litter and the hot air can be increased. And the rotating bent rod 2011 will stir the cat litter on the plate surface of the dispersing plate 202 to increase the falling speed and prevent the cat litter from sticking to the plate surface. The dried cat litter falls to the bottom wall of the drying box 1 through the mesh holes of the sieve 203 and is discharged from the discharge pipe 101.
