Two sets of protrusions are installed at the bottom of the collection box, and two sets of grooves are provided on the inner bottom wall of the collection box for the protrusions to engage.

[0008] Furthermore, the drive mechanism includes a first motor fixedly mounted on the top bracket of the collection box, a first rotating rod fixedly connected to the output end of the first motor, a first gear fixedly mounted on the first rotating rod, a threaded rod rotatably mounted on the inner top of the bracket, a second gear fixedly mounted on the threaded rod, the second gear meshing with the first gear, a cross plate threadedly mounted on the threaded rod, and a set of push rods mounted at each of the four ends of the cross plate, the ends of the four sets of push rods passing through the collection box and connected to a pressure plate.

[0009] Furthermore, sliders are installed on both sides of the cross plate, and the inner wall of the bracket is provided with grooves corresponding to the sliders. The two sets of sliders are slidably installed in the two sets of grooves respectively.

[0010] Furthermore, a flow guide seat is installed inside the crushing chamber, the flow guide seat corresponds to the discharge port, and the upper surface of the flow guide seat is inclined towards the discharge port. The flow guide seat is located below the crushing roller inside the crushing chamber.

[0011] Furthermore, the end of the guide seat extends through the outlet and into the inlet of the collection box.

[0012] Furthermore, the inner wall of the collection box is provided with a limiting block in the circumferential direction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: A waste collection device, such as Figures 1-4 As shown, the device includes a collection box 1 and a crushing box 9 located on one side of the collection box 1. A feed inlet 14 is provided on one side of the collection box 1, and a discharge outlet 13 corresponding to the feed inlet 14 is provided on one side of the crushing box 9. A collection box 2 for collecting waste is provided at the bottom of the inner cavity of the collection box 1, and the upper end of the collection box 2 is open. A pressing assembly 3 for compressing the waste in the collection box 2 is provided inside the inner cavity of the collection box 1. The pressing assembly 3 includes a pressure plate 38 and a driving mechanism for driving the pressure plate 38 to move up and down. The pressure plate 38 is located above the collection box 2, and the outer wall of the pressure plate 38 is adapted to the inner wall of the collection box 2.

[0023] In use, the waste material is crushed by the crushing roller 104 in the crushing box 9. The crushed waste material is discharged from the discharge port 13 of the crushing box 9 and slides into the collection box 2 through the inlet 14 of the collection box 1. After a certain amount of waste material is collected in the collection box 2, the pressure plate 38 is driven to move downward by the drive mechanism. The pressure plate 38 is used to compress the waste material in the collection box 2. After compression, the collection box 2 is taken out from the collection box 1 and the compressed waste material is transferred.

[0024] Furthermore, such as Figure 2 and Figure 3As shown, a bracket 4 is installed on the top of the collection box 1. The drive mechanism includes a first motor 31 fixedly installed on the top of the bracket 4. The output end of the first motor 31 is fixedly connected to a first rotating rod 32 via a coupling. A first gear 33 is fixedly installed on the first rotating rod 32. A threaded rod 34 is rotatably installed on the inner top of the bracket 4. A second gear 35 is fixedly installed on the threaded rod 34. The second gear 35 meshes with the first gear 33, and the size of the second gear 35 is larger than the size of the first gear 33, that is, the first gear 33 is a small gear and the second gear 35 is a large gear. A cross plate 36 is threadedly installed on the threaded rod 34. The cross plate 36 has four ends, and each end is equipped with a set of push rods 37. The ends of the four sets of push rods 37 pass through the collection box 1 and are connected to the pressure plate 38 located inside the collection box 1.

[0025] In use, the first motor 31 drives the first gear 33 to rotate via the first rotating rod 32, which in turn drives the second gear 35 and the threaded rod 34 meshing with it to rotate. Since the threaded rod 34 is threadedly connected to the cross plate 36, the rotation of the threaded rod 34 drives the cross plate 36 to move up and down along the direction of the threaded rod 34. The push rod 37 at the end of the cross plate 36 moves together with the cross plate 36, pushing the pressure plate 38 to compress the waste in the collection box 2. By setting the cross plate 36 and four sets of push rods 37, it is ensured that the pressure plate 38 is subjected to uniform pressure during the compression of waste, avoiding local over-tightening or over-loosening of the waste, and improving the compression effect.

[0026] Slider 5 is installed on both sides of the cross plate 36. The inner wall of the bracket 4 is provided with a groove 6 corresponding to the slider 5. The groove 6 is set vertically, and the two sets of slider 5 are slidably installed in the two sets of groove 6 respectively.

[0027] The slider 5 and the slide groove 6 work together to provide a stable guide for the up and down movement of the cross plate 36. When the cross plate 36 moves within the bracket 4, the slider 5 slides along the slide groove 6 to ensure that the movement trajectory of the cross plate 36 is straight and stable, avoiding deviation or shaking.

[0028] Furthermore, such as Figure 2 As shown, a limiting block 15 is provided circumferentially on the inner wall of the collection box 1. The limiting block 15 is located above the pressure plate 38, and the width of the limiting block 15 is greater than the distance between the outer wall of the pressure plate 38 and the inner wall of the collection box 1. By setting the limiting block 15, on the one hand, the upward movement of the pressure plate 38 is limited; on the other hand, since the pressure plate 38 is adapted to the collection box 2, there is a certain gap between the outer wall of the pressure plate 38 and the inner wall of the collection box 1. When the crushed waste slides into the collection box 2, there is a situation where small particles of waste are transferred to the upper surface of the pressure plate 38 through this gap. By the pressure plate 38 abutting against the limiting block 15, the upper part of the collection box 2 is partially blocked, thereby improving or reducing the transfer of small particles of waste to the upper surface of the pressure plate 38.

[0029] Furthermore, the collection box 1 includes a box body 101 and a door 102. The door 102 is installed on the box body 101 via a hinge. Opening the door 102 allows for the placement and removal of the collection box 2, as well as the cleaning of the components inside the box body 101. Preferably, a limiting block 15 is also provided on the inner wall of the door 102. The limiting block 15 on the inner wall of the door 102 cooperates with the limiting block 15 on the inner wall of the box body 101 to block the top of the collection box 2. It should be noted that the limiting block 15 is installed above the feed inlet 14 to avoid interfering with the feeding of the feed inlet 14.

[0030] Preferably, the door 102 is provided with an observation window 16, which can be used to view the amount of waste collected in the collection box 2, the compaction state of the waste, the position of the pressure plate 38, the cleanliness of the inner cavity of the box 101, and the feeding of waste.

[0031] Furthermore, two sets of protrusions 7 are installed at the bottom of the collection box 2, and two sets of grooves 8 are provided on the inner bottom wall of the collection box 1 for the protrusions 7 to engage. Through the cooperation of the protrusions 7 and the grooves 8, the collection box 2 can be quickly and accurately positioned when placed into the collection box 1. Operators do not need to spend extra time and effort adjusting the position of the collection box 2, improving work efficiency and preventing the collection box 2 from moving or tilting during waste processing, thus ensuring the accuracy and efficiency of waste collection.

[0032] like Figure 4 As shown, the crushing box 9 is equipped with a crushing assembly 10 for crushing waste materials. The crushing assembly 10 includes a second motor 101 installed on one side of the crushing box 9. The output shaft of the second motor 101 is fixedly connected to a second rotating rod 102 via a coupling. One end of the second rotating rod 102 is rotatably installed on one side of the crushing box 9. A drive wheel 103 is fixedly installed on the second rotating rod 102. Two sets of crushing rollers 104 are rotatably installed inside the crushing box 9. One end of one set of crushing rollers 104 passes through the crushing box 9 and is fixedly installed with a driven wheel 105. The drive wheel 103 and the driven wheel 105 are connected by a toothed belt 106. The other ends of both sets of crushing rollers 104 pass through the crushing box 9 and are equipped with a third gear 107. The third gears 107 mesh with each other.

[0033] The second motor 101 drives the second rotating rod 102 to rotate, which in turn drives the two sets of crushing rollers 104 to rotate through the driving wheel 103, the toothed belt 106 and the driven wheel 105. Since the two sets of third gears 107 mesh with each other, the two sets of crushing rollers 104 rotate relative to each other, thereby crushing the incoming waste material.

[0034] Furthermore, a guide seat 11 is installed inside the crushing chamber 9. The guide seat 11 corresponds to the discharge port 13, and its upper surface is inclined towards the discharge port 13. The guide seat 11 is located below the crushing roller 104. By setting the guide seat 11, the crushed waste material can leave the crushing chamber 9 more easily, reducing the amount of waste material remaining in the crushing chamber 9. This helps to keep the crushing chamber 9 clean and reduces the difficulty and frequency of subsequent cleaning work.

[0035] The top of the crushing box 9 is connected to the feed hopper 12. The discharge port 13 of the crushing box 9 is opposite to the feed port 14 of the collection box 1. The end of the guide seat 11 extends into the feed port 14 after passing through the discharge port 13. By setting the feed hopper 12, waste can be easily poured into the crushing box 9. By extending the end of the guide seat 11 into the feed port 14, it is ensured that the crushed waste flows smoothly from the crushing box 9 into the collection box 1, avoiding the accumulation or blockage of waste in the crushing box 9, and ensuring the continuity and stability of waste collection. It should be noted that the part of the guide seat 11 located in the feed port 14 should not interfere with the up and down movement of the pressure plate 38. Preferably, the crushing box 9 has a door with an observation window. The crushing status of the waste can be viewed through the observation window. If the crushed waste blocks the discharge port 13, the door can be opened for processing.

[0036] When the above-mentioned waste collection device is used, waste (such as polyurethane foam) is fed into the crushing box 9 from the feed hopper 12. The crushing roller 104 crushes the waste. The crushed waste slides down into the collection box 2 through the guide seat 11. After a certain amount of waste is collected in the collection box 2, the pressure plate 38 is driven to move downward by the drive mechanism. The pressure plate 38 compresses the waste in the collection box 2. After compression, the collection box 2 is taken out from the collection box 1 and the compressed waste is transferred.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
