Description

Technical Field

[0001] This application belongs to the field of raw material grinding, and specifically relates to a raw material grinding device. Background Technology

[0002] Chemical raw materials, such as lumpy or coarse-grained materials, generally need to be ground before use. Grinding increases the specific surface area of ​​the material, which can accelerate the chemical reaction rate between solids and liquids, and between solids and solids, improve the conversion and utilization rate of raw materials, improve the dissolution and dispersion of powders, prevent material agglomeration, and make the mixture of various raw materials more uniform. This optimizes the fineness, color, filling performance, and molding quality of the product, reduces the energy consumption of subsequent processing, and meets the production process and finished product performance requirements of various chemical products such as coatings, lithium batteries, inorganic fillers, and catalysts. The ball mill is a commonly used raw material grinding device in chemical experimental reactions. Through the grinding media inside the rotating cylinder, chemical raw materials are uniformly ground into micro-powders or uniform particles. The ball mill can effectively increase the surface area of ​​the raw materials, promote the reaction rate and uniformity, thereby improving the efficiency and repeatability of experiments. However, existing ball mills suffer from material accumulation inside, resulting in poor grinding effects.

[0003] Chinese patent CN215464752U discloses a raw material grinding device for chemical experimental reactions, including a base plate, a crushing device, a sliding device, a grinding mechanism, and a screening device. A support plate and a first support frame are symmetrically installed on the upper side of the base plate. The lower end face of the support plate is fixedly connected to the upper end face of the base plate, and the lower end face of the first support frame is fixedly connected to the upper end face of the support plate. This invention provides a raw material grinding device for chemical experimental reactions. Raw materials enter the outer shell through a feed pipe. A first and second grinding roller mesh to crush large pieces of raw material. The crushed raw material enters the grinding chamber through a chute. The rotating column rotates, causing the pulley and sliding column to slide back and forth on the sliding rod, thereby moving the grinding balls within the grinding chamber, enabling the grinding balls to thoroughly grind the raw material. However, this grinding device currently has the following problem: raw materials accumulate or pile up inside the device, making it difficult for the grinding balls to effectively contact and grind the raw material, thus reducing the grinding effect.

[0004] Chinese patent CN211099492U discloses a grinding device for chemical production, including a housing. A feed inlet is located at the center of the top of the housing, and a feed pipe is fixedly connected to the inlet. An observation port is located at the center of one end of the housing, and a protective mesh is embedded inside the observation port. Multiple heat dissipation grooves are located at the center of both sides of the housing, and dustproof mesh is embedded inside each of the heat dissipation grooves. Universal wheels are fixedly installed at the four corners of the bottom of the housing, and foot brakes are fixedly installed on the top of each of the four universal wheels. A crushing structure is provided inside the housing, and scrapers are fixedly installed at the bottom of the side walls of the housing, with multiple openings at the top of the scrapers. This grinding device uses a swing plate that oscillates back and forth. During the oscillation process, the swing plate, in conjunction with a fixed plate, squeezes the chemical raw material, breaking large pieces of sliding raw material into smaller shapes. However, the grinding effect is poor, and smaller particles cannot be fully ground. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention proposes a raw material grinding device for chemical experimental reactions, which avoids the accumulation of raw materials in the device and improves the grinding effect.

[0006] The technical solution adopted in this invention is as follows: A raw material grinding device includes a main body for grinding raw materials, a feed inlet at the top of the main body, an anti-accumulation component inside the main body, an anti-clogging component outside the anti-accumulation component, a grinding component below the anti-accumulation component, a groove at the bottom of the grinding component, and a collection box for temporarily storing raw materials below the groove, the collection box being slidably connected to the main body of the device.

[0007] Furthermore, the main body of the device is a vertical cylindrical body, which includes a top plate, a bottom plate and a side plate connected between the top plate and the bottom plate. The top plate has a circular through hole and the side plate has a limiting through groove for the collection box to slide.

[0008] Furthermore, the feed inlet is located on the top plate. The feed inlet is a thin-walled frustum-shaped body that is wider at the top and narrower at the bottom, with openings at both ends. The bottom port of the feed inlet is connected to a circular through hole in the top plate. A radial support frame is fixedly connected to the inner wall of the feed inlet. A motor is fixed to the top of the support frame. The power output end of the motor is connected to a rotating shaft. The rotating shaft is coaxial with the main body of the device and extends into the interior of the main body of the device. The motor drives the rotating shaft to rotate. A fixing block is fixedly connected to the circumferential surface of the rotating shaft. A baffle is fixedly connected to the side of the fixing block. The baffle is arc-shaped or fan-shaped and is located below the feed inlet. The baffle rotates synchronously with the rotating shaft, intermittently blocking the feed inlet to achieve controlled feeding and prevent excessive material from clogging at one time. When the baffle rotates, it periodically passes directly below the feed inlet. When it rotates to the bottom of the feed inlet, it blocks the feed inlet; when it rotates to the top, it allows the feed to pass through, thus achieving intermittent feeding.

[0009] Furthermore, the anti-accumulation component includes a feeding frame coaxially fitted to the outside of the rotating shaft, multiple impact plates disposed on the top of the feeding frame, multiple crushing blades arranged inside the feeding frame, a fixing ring connected to the top of the crushing blades, multiple long rods connected above the fixing ring and arranged axially, a moving block fixed to the top of the long rods, an L-shaped block disposed on one side of the moving block, a connecting plate disposed on the other side of the moving block, an arc plate connected to the end of the connecting plate and colliding with the impact plates, and a spring arranged between the moving block and the main body of the device. The feeding frame is a hollow annular cylindrical body with an open top. The feeding frame rotates synchronously with the rotating shaft. The feeding frame includes side walls and a bottom wall. A central hole for the rotating shaft to pass through is opened in the center of the bottom wall. Multiple feeding ports for material to pass through are distributed on the bottom wall. Multiple impact plates are arranged circumferentially on the top edge of the feeding frame. The impact plates extend in a direction away from the feeding frame. The impact plates have a smooth arc-shaped first curved surface. The device features a downwardly curved surface that serves as the impact working surface. A single crushing blade is arranged radially along the feeding frame, with its length less than the radius of the bottom wall. Multiple crushing blades are evenly distributed around the rotating shaft and simultaneously fixed to a fixed ring. The number of long rods matches the number of impact plates, and these long rods are evenly distributed circumferentially along the fixed ring. The L-shaped block includes vertically connected blocks and horizontal blocks. The top of the vertical block is fixedly connected to the main body of the device. The horizontal block has a limiting hole for the long rods to pass through. The shape of the limiting hole matches the cross-sectional shape of the long rods, allowing them to pass through precisely. An arc plate extends downwards towards the connecting plate and has a smooth, curved second surface. The bending direction of the second surface is opposite to that of the first surface. The second and first surfaces serve as each other's impact working surfaces. The arc plate is located on the displacement trajectory of the impact plate. The two ends of the spring are fixedly connected to the main body of the device and the moving block, respectively. Raw materials enter the main body of the device through the feed inlet and fall into the feed frame. The feed frame rotates synchronously with the rotating shaft. During the rotation of the feed frame, the impact plate collides with the arc plate. The feed frame continues to rotate, and the arc plate is raised. The arc plate, along with the connecting plate, moving block, long rod, fixing ring, and crushing blade, moves upward. The spring is compressed. When the impact plate passes the arc plate, under the elastic force of the spring and the gravity of the arc plate, connecting plate, moving block, long rod, fixing ring, and crushing blade, the arc plate, connecting plate, moving block, long rod, fixing ring, and crushing blade move downward. When it encounters the next impact plate, the above action is repeated to realize the reciprocating motion of the crushing blade. During the downward movement, the crushing blade pre-crushes the moving raw material. The pre-crushed raw material is discharged through the feed inlet and falls onto the grinding component. The feed frame is used to complete the feeding and pre-crushing. Through the reciprocating motion of the crushing blade, larger particles of raw material are crushed, so that they can smoothly pass through the feed inlet and enter the grinding component.

[0010] Furthermore, the anti-accumulation component includes multiple abutment plates distributed around the outer periphery of the feeding frame, multiple fixed plates fixed to the inner wall of the main body of the device, a short rod vertically connected to the fixed plate, a striking plate rotatably connected to the short rod, and a torsion spring connecting the striking plate and the fixed plate. The abutment plates are arc-shaped thin plates that fit against the outer wall of the feeding frame and are arranged vertically. The striking plate is an arc-shaped plate with a limiting groove at its root. The short rod is arranged in the limiting groove, and the striking plate rotates around the short rod. The bending direction of the striking plate is the same as that of the abutment plate. The striking plate is located on the outside of the abutment plate. One end of the torsion spring abuts against the fixed plate, and the other end presses against the striking plate. The side of the striking plate away from the limiting groove presses inward against the outer wall of the feeding frame under the torsion of the torsion spring. The striking plate is located on the displacement trajectory of the abutment plate. During the rotation of the feeding frame, the contact plate touches the striking plate. The feeding frame continues to rotate, and the contact plate pushes the striking plate outward, causing the torsion spring to twist synchronously. When the contact plate passes the striking plate, the torsion spring uses its own elasticity to drive the striking plate to reset. The reset of the striking plate strikes the feeding frame, increasing the speed at which the raw material is discharged from the feeding port, preventing the raw material from blocking the feeding port, and knocking off the raw material stuck to the wall.

[0011] Furthermore, the grinding assembly includes a grinding block located below the feeding frame and fixedly connected coaxially to the rotating shaft, and a placement block arranged around the grinding block. The grinding block includes a positive cone that is narrower at the top and wider at the bottom, and an inverted cone that is wider at the top and narrower at the bottom. There is a certain gap between the positive cone and the feeding frame. The gap is used to ensure that the raw material discharged from the feeding port can fall smoothly onto the positive cone. At the same time, the positive cone has an inclined surface to accelerate the falling speed. The positive cone and the inverted cone are integrally formed. The conical surface of the inverted cone is provided with grinding teeth or abrasive surface. The grinding block rotates synchronously with the rotating shaft and cooperates with the placement block to squeeze and grind the raw material. The placement block is an annular or bowl-shaped grinding seat. The placement block includes an annular vertical plate and an inverted conical support plate located inside the vertical plate and recessed downwards. The vertical plate is fixedly connected to the inner wall of the main body of the device. The top edge of the vertical plate is connected to the top edge of the support plate. The support plate is located directly below the inverted cone. The bottom end of the support plate has a round opening. The opening is formed by a section of... A cylindrical thin-walled body extends downwards, with the top edge of the slot connected to the circular opening of the support plate. The inner diameter of the support plate is larger than the maximum diameter of the inverted cone. The connection point between the cone and the inverted cone is lower than the top edge of the vertical plate. There is a certain gap between the support plate and the inverted cone, which is smaller closer to the slot. A support plate is provided below the placement block and is also arranged above the collection box. The support plate is circular, and its outer periphery is fixedly connected to the inner wall of the main body of the device. The bottom end of the vertical plate is fixedly connected to the top surface of the support plate. The support plate is used to support the placement block and improve its stability. An opening for material to pass through is opened in the center of the support plate. The opening can be circular, for example, and is directly opposite the slot. The bottom edge of the slot is connected to the support plate on the outer periphery of the opening. Since the top edge of the slot is connected to the circular opening of the support plate and the bottom edge of the slot is connected to the support plate on the outer periphery of the opening, it ensures that all materials fall into the collection box and prevents powder from flying away. The raw material discharged from the feed port falls onto the surface of the cone and rolls into the gap between the support plate and the inverted cone. The grinding block rotates with the shaft, rotating and crushing the raw material that falls into the placement block, grinding it into fine particles, and then discharging it sequentially through the slot and the opening of the support plate. The raw material is pre-crushed in the feed frame before entering the placement block to avoid a large amount of raw material entering the placement block at the same time, which would cause the raw material in the placement block to accumulate and reduce the grinding effect.

[0012] Furthermore, the collection box is an open storage box located directly below the trough opening. It is used to collect raw materials falling from the trough opening. For example, the collection box can be rectangular. The collection box has two oppositely arranged arc-shaped sidewalls. The shape of the arc-shaped sidewalls is adapted to the shape of the limiting through groove. The arc-shaped sidewalls of the collection box are provided with handles to facilitate pushing and pulling the collection box, taking it out or putting it back.

[0013] Furthermore, a support leg is fixedly connected to the bottom of the main body of the device. Beneficial effects

[0014] This invention discloses a raw material grinding device. Through the configuration of an anti-accumulation component, the feeding frame, feeding port, and rotating shaft work together to allow raw materials to enter the feeding frame from the inlet, and then enter the placement block from the feeding port within the feeding frame. This prevents a large amount of raw material from simultaneously entering the placement block, causing accumulation and reducing the grinding effect. Simultaneously, the feeding frame, L-shaped block, moving block, long rod, connecting plate, arc plate, impact plate, spring, fixing ring, connecting plate, and crushing blade work together. The spring's reset causes the moving block, long rod, fixing ring, crushing blade, connecting plate, and arc plate to reset. This reciprocating motion of the crushing blade allows it to crush larger particles of raw material, enabling them to pass smoothly through the feeding port into the placement block. Furthermore, the fixed block and baffle work together. The rotation of the fixed block causes the baffle to rotate, indirectly blocking the inlet and preventing excessive material from clogging the feeding frame. By using the anti-clogging components, a fixed plate, short rod, striking plate, torsion spring, and abutment plate work together to ensure that when the abutment plate rotates without hitting the striking plate, the torsion spring will use its own elasticity to drive the striking plate to reset. The reset of the striking plate will strike the feeding frame, thereby increasing the speed at which the raw material is fed from the feeding port and preventing blockage of the feeding port.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a raw material grinding device includes a device body 1 for grinding raw materials. The top of the device body 1 is provided with a feed inlet 5. The inside of the device body 1 is provided with an anti-accumulation component 2. The outside of the anti-accumulation component 2 is provided with an anti-blocking component 3. Below the anti-accumulation component 2 is a grinding component. The bottom of the grinding component is provided with a groove 11. Below the groove 11 is a collection box 12 for temporarily storing raw materials. The collection box 12 is slidably connected to the device body 1.

[0023] The main body 1 of the device is a vertical cylindrical body. The main body 1 of the device includes a top plate 101, a bottom plate and a side plate 102 connecting the top plate 101 and the bottom plate. A circular through hole is opened on the top plate 101 and a limiting through groove is opened on the side plate 102 for the collection box 12 to slide.

[0024] The feed inlet 5 is located on the top plate 101. The feed inlet 5 is a thin-walled frustum-shaped body that is wider at the top and narrower at the bottom and open at both ends. The bottom port of the feed inlet 5 is connected to a circular through hole in the top plate 101. A radial support frame 6 is fixedly connected to the inner wall of the feed inlet 5. A motor 7 is fixed to the top of the support frame 6. The power output end of the motor 7 is connected to a rotating shaft 8. The connection between the motor 7 and the rotating shaft 8 adopts a common method in the art. The rotating shaft 8 is coaxially arranged with the main body 1 of the device and extends into the interior of the main body 1 of the device. The motor 7 drives the rotating shaft 8 to rotate. A fixing block 23 is fixedly connected to the circumferential surface of the rotating shaft 8. A baffle 24 is fixedly connected to the side of the fixing block 23. The baffle 24 is arc-shaped or fan-shaped and is located below the feed inlet 5. The baffle 24 rotates synchronously with the rotating shaft 8, intermittently blocking the feed inlet 5 to achieve controlled feeding and prevent excessive feeding at one time from causing blockage. When the baffle 24 rotates, it periodically passes directly below the feed inlet 5. When it rotates to the bottom of the feed inlet 5, it blocks the feed inlet; when it rotates to the bottom, it allows the feed to pass through, thus achieving intermittent feeding.

[0025] The anti-accumulation component 2 includes a feeding frame 21 coaxially mounted on the outside of the rotating shaft 8, multiple impact plates 210 disposed on the top of the feeding frame 21, multiple crushing blades 213 disposed inside the feeding frame 21, a fixing ring 212 connected to the top of the crushing blades 213, multiple long rods 27 connected above the fixing ring 212 and arranged axially, a movable block 26 fixed to the top of the long rods 27, an L-shaped block disposed on one side of the movable block 26, a connecting plate 28 disposed on the other side of the movable block 26, and an arc plate 29 connected to the end of the connecting plate 28 and colliding with the impact plates 210. The spring 211 between the moving block 26 and the main body 1; the feeding frame 21 is a hollow annular cylindrical body with an open top; the feeding frame 21 rotates synchronously with the rotating shaft 8; the feeding frame 21 includes side walls and a bottom wall; the center of the bottom wall has a central hole for the rotating shaft 8 to pass through; multiple feeding ports 22 for material to pass through are distributed on the bottom wall; multiple impact plates 210 are arranged in a circumferential array on the top edge of the feeding frame 21; the impact plates 210 extend in a direction away from the feeding frame 21; the impact plates 210 have a smooth arc-shaped first curved surface 2101; the first curved surface 2101 bends downwards gently and... As the impact working surface, a single crushing blade 213 is arranged radially along the feeding frame 21. The length of the crushing blade 213 is less than the radius of the bottom wall. Multiple crushing blades 213 are evenly distributed around the rotating shaft 8. Multiple crushing blades 213 are simultaneously fixedly connected to the fixing ring 212. The number of long rods 27 is the same as the number of impact plates 210. Multiple long rods 27 are evenly distributed circumferentially along the fixing ring 212. The L-shaped block includes a vertical block 2501 and a horizontal block 2502 that are perpendicularly connected to each other. The top of the vertical block 2501 is fixedly connected to the main body 1 of the device. The horizontal block 2502 has a protrusion for the long rods. The rod 27 passes through a limiting hole, the shape of which is adapted to the cross-sectional shape of the long rod 27 and allows the long rod 27 to pass through exactly. The arc plate 29 extends downward toward the connecting plate 28. The arc plate 29 has a smooth arc-shaped second curved surface 2901. The bending direction of the second curved surface 2901 is opposite to the bending direction of the first curved surface 2101. The second curved surface 2901 and the first curved surface 2101 become each other's impact working surfaces. The arc plate 29 is located on the displacement trajectory of the impact plate 210. The two ends of the spring 211 are fixedly connected to the main body 1 and the moving block 26, respectively.Raw materials enter the main body 1 of the device through the feed inlet 5 and fall into the feed frame 21. The feed frame 21 rotates synchronously with the rotating shaft 8. During the rotation of the feed frame 21, the impact plate 210 collides with the arc plate 29. The feed frame 21 continues to rotate, and the arc plate 29 is raised. The arc plate 29 moves upward along with the connecting plate 28, the moving block 26, the long rod 27, the fixing ring 212, and the crushing blade 213. The spring 211 is compressed. After the impact plate 210 passes the arc plate 29, under the elastic force of the spring 211 and the weight of the arc plate 29, the connecting plate 28, the moving block 26, the long rod 27, the fixing ring 212, and the crushing blade 213, the raw materials are compressed. Under the action of force, the arc plate 29, connecting plate 28, moving block 26, long rod 27, fixing ring 212, and crushing blade 213 move downward. When they encounter the next impact plate 210, the above actions are repeated to realize the reciprocating motion of the crushing blade 213. During the downward movement, the crushing blade 213 pre-crushes the moving raw material. The pre-crushed raw material is discharged through the feed port 22 and falls onto the grinding assembly. The feed frame 21 is used to complete the feeding and pre-crushing. Through the reciprocating motion of the crushing blade 213, larger particles of raw material are crushed, so that they can smoothly enter the grinding assembly through the feed port 22.

[0026] The anti-stacking component 2 includes multiple abutment plates 35 distributed around the outer periphery of the feeding frame 21, multiple fixing plates 31 fixed to the inner wall of the main body 1, short rods 32 vertically connected to the fixing plates 31, a striking plate 33 rotatably connected to the short rods 32, and a torsion spring 34 connecting the striking plate 33 and the fixing plates 31. The abutment plates 35 are arc-shaped thin plates that fit against the outer wall of the feeding frame 21 and are arranged vertically. The striking plates 33 are arc-shaped plates with a base of [missing information]. There is a limiting groove, and a short rod 32 is arranged in the limiting groove. The striking plate 33 rotates around the short rod 32. The bending direction of the striking plate 33 is the same as the bending direction of the abutment plate 35. The striking plate 33 is set on the outside of the abutment plate 35. One end of the torsion spring 34 abuts against the fixed plate 31, and the other end abuts against the striking plate 33. The side of the striking plate 33 away from the limiting groove is pressed inward against the outer wall of the feeding frame 21 under the action of the torsion force of the torsion spring 34. The striking plate 33 is located on the displacement trajectory of the abutment plate 35. During the rotation of the feeding frame 21, the contact plate 35 touches the striking plate 33. The feeding frame 21 continues to rotate, and the contact plate 35 pushes the striking plate 33 to deflect outward, causing the torsion spring 34 to twist synchronously. When the contact plate 35 passes the striking plate 33, the torsion spring 34 uses its own elasticity to drive the striking plate 33 to reset. The reset of the striking plate 33 strikes the feeding frame 21, increasing the speed at which the raw material is discharged from the feeding port 22, preventing the raw material from blocking the feeding port 22, and knocking off the raw material stuck to the wall.

[0027] The grinding assembly includes a grinding block 9 located below the feeding frame 21 and coaxially fixedly connected to the rotating shaft 8, and a placement block 10 arranged around the grinding block 9. The grinding block 9 includes a positive cone that is narrower at the top and wider at the bottom, and an inverted cone that is wider at the top and narrower at the bottom. There is a certain distance between the positive cone and the feeding frame 21, for example, 20-50mm, to ensure that the raw material discharged from the feeding port 22 can fall smoothly onto the positive cone. At the same time, the positive cone has an inclined surface to accelerate the falling speed. The positive cone and the inverted cone are integrally formed. The conical surface of the inverted cone is provided with grinding teeth or a frosted surface. The grinding block 9 rotates synchronously with the rotating shaft 8 and is placed around the placement block 10. 0. For extruding and grinding raw materials, the placement block 10 is an annular or bowl-shaped grinding seat. The placement block 10 includes an annular vertical plate 1001 and an inverted conical support plate 1002 recessed downwards and located inside the vertical plate 1001. The vertical plate 1001 is fixedly connected to the inner wall of the device body 1. The top edge of the vertical plate 1001 is connected to the top edge of the support plate 1002. The support plate 1002 is located directly below the inverted cone. The bottom end of the support plate 1002 has a circular opening 11, which is formed by a downwardly extending cylindrical thin-walled section. The top edge of the groove 11 is connected to the circular opening of the support plate 1002. The inner diameter of plate 1002 is larger than the maximum diameter of the inverted cone. The position where the upright cone connects to the inverted cone (this position is at the maximum diameter of the inverted cone or upright cone) is lower than the top edge of the vertical plate 1001. There is a certain gap between the support plate 1002 and the inverted cone. The closer to the slot 11, the smaller the gap. Since the position where the upright cone connects to the inverted cone is lower than the top edge of the vertical plate 1001, it is ensured that all the material enters the gap between the support plate 1002 and the inverted cone. Preferably, a support plate 36 is provided below the placement block 10, and the support plate 36 is arranged above the collection box 12. The support plate 36 is circular. The outer periphery of plate 6 is fixedly connected to the inner wall of the main body 1. The bottom end of the vertical plate 1001 is fixedly connected to the top surface of the support plate 36. The support plate 36 is used to support the placement block 10 and improve the stability of the placement block 10. The center of the support plate 36 has an opening for material to pass through. The opening can be circular, for example. The opening is directly opposite the slot 11. The bottom edge of the slot 11 is connected to the support plate 36 on the outer periphery of the opening. Since the top edge of the slot 11 is connected to the circular opening of the support plate 1002 and the bottom edge of the slot 11 is connected to the support plate 36 on the outer periphery of the opening, it is ensured that all materials fall into the collection box 12 and powder is prevented from flying away. The raw material discharged from the discharge port 22 falls onto the surface of the cone and rolls into the gap between the support plate 1002 and the inverted cone. The grinding block 9 rotates with the rotating shaft 8 to rotate and grind the raw material falling into the placement block 10, grind the raw material finely, and discharge it in sequence through the slot 11 and the opening of the support plate 36. The raw materials are pre-crushed in the feeding frame 21 before entering the placement block 10, which avoids a large amount of raw materials entering the placement block 10 at the same time, causing the raw materials in the placement block 10 to accumulate and reduce the grinding effect.

[0028] The collection box 12 is an open storage box located directly below the slot 11. It is used to collect raw materials that fall from the slot 11. The collection box 12 can be, for example, a cuboid shape. The collection box 12 has two oppositely arranged arc-shaped sidewalls. The shape of the arc-shaped sidewalls is adapted to the shape of the limiting through slot. The arc-shaped sidewalls of the collection box 12 are provided with handles to facilitate pushing and pulling the collection box 12, taking it out or putting it back.

[0029] The bottom of the main body 1 of the device is fixedly connected to a support leg 4.

[0030] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
