DETAILED DESCRIPTION

[0035] In order to make the technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0036] The present application provides a technical solution: refer to Figure 1 Figure 14 The fish conveyor disclosed by the present application comprises a shell 1, a conveying assembly 2 is arranged in the shell 1, the conveying assembly 2 comprises a transport belt 21, the transport belt 21 is arranged in the top opening of the shell 1, and the front and rear sides of the transport belt 21 are in contact with the inner wall of the shell 1, a driving mechanism 22 is arranged in the transport belt 21, a plurality of groups of adsorption holes 23 are formed in the outer peripheral wall of the transport belt 21, the spacing between adjacent two groups of adsorption holes 23 is equal, the spacing between adjacent two adsorption holes 23 in each group is equal, a support mechanism 25 is arranged between the plurality of groups of adsorption holes 23, a plurality of air pumps 24 are arranged in the transport belt 21, a water storage tank 215 is arranged in the transport belt 21, the bottom side of the air pump 24 is fixedly connected with the outer wall of the water storage tank 215, a baffle 26 is fixedly arranged at the bottom side of the water storage tank 215, the bottom side of the baffle 26 is in contact with the inner wall of the transport belt 21, the front and rear sides of the baffle 26 are fixedly connected with the inner wall of the shell 1, a deflector 27 is arranged above the water storage tank 215, the top side of the deflector 27 is in contact with the inner wall of the transport belt 21, the front and rear sides of the deflector 27 are fixedly connected with the inner wall of the shell 1, a plurality of conduits 28 are fixedly and penetratively arranged at the middle position of the bottom side of the deflector 27, and the bottom end of each conduit 28 is inserted into the bottom of the water storage tank 215.

[0037] A cleaning assembly 3 is arranged on the shell 1, the plurality of air pumps 24 and the cleaning assembly 3 are provided with an exhaust mechanism 29, and a debris collection assembly 4 is arranged at the bottom of the shell 1.

[0038] ​In this embodiment, when the improved fish conveyor is in use, the drive mechanism 22 first drives the conveyor belt 21 to rotate continuously at a uniform speed. At the same time, the air pump 24 starts and continuously draws gas between the conveyor belt 21 and the inner wall of the outer shell 1, so that a negative pressure cavity is formed between the conveyor belt 21 and the inner wall of the outer shell 1. At this time, due to the blocking of the suction holes 23 of the conveyor belt 21 by the drive roller 221, the blocking of the suction holes 23 of the conveyor belt 21 by the baffle 26, and the blocking of the suction holes 23 on the conveyor belt 21 by the guide plate 27, the gas on the top side of the conveyor belt 21 continuously passes through the conveyor belt 21. The adsorption holes 23 on the top side flow into the guide plate 27 and through the conduit 28 into the water in the water storage tank 215. Then, the water in the water storage tank 215 emerges and flows in from the top opening of the water storage tank 215 to replenish most of the gas lost between the conveyor belt 21 and the inner wall of the outer shell 1. Some of the gas at the bottom of the outer shell 1 flows into the space between the conveyor belt 21 and the inner wall of the outer shell 1 through the adsorption holes 23 between the baffle 26 and the drive roller 221 to replenish the other part of the gas lost between the conveyor belt 21 and the inner wall of the outer shell 1. The device is then started.

[0039] When the fish is placed on the conveyor belt 21, the gas pushes the fish, which applies an adsorption force to the fish, making the fish stable on the conveyor belt 21. At this time, the fish moves in a linear trajectory as the conveyor belt 21 rotates. When the fish moves to the bottom of the cleaning component 3, most of the gas drawn by the air pump 24 flows into the cleaning component 3 through the exhaust mechanism 29. The cleaning component 3 causes the gas to form multiple inclined high-speed airflows that blow on the fish in sequence. At the same time, due to the support mechanism 25 supporting the fish, there is a certain gap between the bottom of the fish and the conveyor belt 21. At this time, the airflow flows on the bottom of the fish when it flows into the adsorption hole 23. Finally, the surface of the fish is covered with flowing airflow, which blows off fish scales or sewage and other debris, making the fish relatively clean. During the transportation process, the fish will not discharge sewage or fish scales and debris into the subsequent processing device or the fish storage box 42.

[0040] Water and particulate debris blown off the fish are carried by the airflow into the water storage tank 215 for storage, while large debris such as fish scales are directly adsorbed onto the conveyor belt 21 and move with the conveyor belt 21, falling into the debris collection component 4 for storage. This facilitates the collection and cleaning of debris, and almost no debris adheres to the conveyor, reducing the frequency of conveyor cleaning and thus reducing the workload of the operator when using the device.

[0041] In a further preferred embodiment of the invention, such as Figure 1 , Figure 3 and Figure 4As shown, the drive mechanism 22 includes two drive rollers 221. The conveyor belt 21 is a soft metal belt. The two drive rollers 221 are arranged opposite to each other in the conveyor belt 21. The outer peripheral wall of each drive roller 221 is interference-fitted with the inner wall of the conveyor belt 21. Both ends of the drive roller 221 rotatably penetrate the shell wall of the outer casing 1. The front side of the outer casing 1 is fixedly equipped with a driver 222, and the drive end of the driver 222 is fixedly connected to the front end of the corresponding drive roller 221.

[0042] In this embodiment, when using the device, the driver 222 and the air pump 24 are started first. The started driver 222 drives the drive roller 221 to rotate continuously. Due to the friction between the drive roller 221 and the conveyor belt 21 and the constraint and limitation of the guide plate 27 and the baffle 26 on the conveyor belt 21, the conveyor belt 21 rotates continuously in the top opening of the outer shell 1 along a fixed trajectory. The tautness of the conveyor belt 21 ensures that when the fish is placed on the conveyor belt 21, the conveyor belt 21 will not bend or deform due to the weight of the fish.

[0043] In a further preferred embodiment of the invention, such as Figure 6 - Figure 8 As shown, annular grooves 223 are provided on both the front and rear sides of the conveyor belt 21. A sealing ring 224 is fixedly installed in the annular groove 223, and the sealing ring 224 is in contact with the inner wall of the outer shell 1.

[0044] In this embodiment, during the rotation of the conveyor belt 21, the sealing ring 224 slides synchronously against the inner wall of the outer shell 1, thereby sealing the gap between the conveyor belt 21 and the inner wall of the outer shell 1. This ensures that the sewage on the conveyor belt 21 will only pass through the conveyor belt 21 through the adsorption hole 23, so that all the sewage drips into the guide plate 27.

[0045] In a further preferred embodiment of the invention, such as Figure 1 - Figure 4 As shown, a stop block 210 is provided on the left side of the conveyor belt 21. The right side of the stop block 210 is arc-shaped and contacts the outer wall of the conveyor belt 21. The stop block 210 is fixedly connected to the inner wall of the outer shell 1. A pad block 211 is provided on the right side of the conveyor belt 21. The left side of the pad block 211 is arc-shaped and fits with the outer wall of the conveyor belt 21 with a clearance. The pad block 211 is fixedly connected to the inner wall of the outer shell 1. A feed hopper 212 is provided on the top side of the stop block 210. The bottom end of the feed hopper 212 is fixedly connected to the top of the stop block 210 and the top of the outer shell 1. The top of the feed hopper 212 is flared. The cross-sectional shape of the inner hole at the bottom of the feed hopper 212 is rectangular.

[0046] In this embodiment, during the use of the above-mentioned device, the operator sequentially puts fish into the feeding hopper 212 through the conveyor. The fish put into the top opening of the feeding hopper 212 slide along the arc surface inside the top opening of the feeding hopper 212, automatically adjusting the angle of the fish so that the fish falls into the bottom of the feeding hopper 212 in a straight state. It should be noted that a certain amount of straight fish can be stacked at the bottom of the feeding hopper 212.

[0047] The baffle 210 can block the gap between the left end of the conveyor belt 21 and the inner wall of the outer shell 1, thereby preventing the fish from getting stuck in the gap between the left end of the conveyor belt 21 and the inner wall of the outer shell 1, which would affect the transportation of the fish.

[0048] After the fish are attached to the conveyor belt 21, the rotating conveyor belt 21 pushes the fish toward the pad 211. After the fish moves to the pad 211, due to the inertia of the fish and the mutual contact between the fish and the left side of the pad 211, the fish gradually slides onto the pad 211, thereby causing the fish to gradually separate from the conveyor belt 21. The fish is discharged from the discharge end of the outer shell 1 and falls into the subsequent processing equipment or the storage equipment used to store the fish.

[0049] In a further preferred embodiment of the invention, such as Figure 4 , Figure 8 and Figure 9 As shown, the top side of the guide plate 27 is a concave arc-shaped surface with the four sides recessed towards the center. The top of the guide tube 28 is coplanar with the arc surface of the guide plate 27. The left and right sides of the guide plate 27 are respectively connected to the outer peripheral walls of the two drive rollers 221. A mesh plate 213 is fixedly installed inside the water storage tank 215, and the guide tube 28 is fixedly inserted through the mesh plate 213. A drain valve 214 is provided on the front side of the outer shell 1 at the position corresponding to the water storage tank 215. The water inlet end of the drain valve 214 is fixedly inserted through the shell wall of the outer shell 1 and the tank wall of the water storage tank 215.

[0050] In this embodiment, after passing through the adsorption hole 23, the gas flows directly into the conduit 28 along the top arc surface of the guide plate 27, and then into the water in the water storage tank 215 along the conduit 28. The gas then travels through the water. When the gas flows to the mesh plate 213, due to the limited gas passage through the holes of the mesh plate 213, the airflow is split into multiple small streams that travel through the water in the water storage tank 215. At this time, water or particulate impurities such as dust in the airflow are trapped and stored in the water due to the adhesion of the water in the water storage tank 215. Opening the drain valve 214 at regular intervals allows excess sewage in the water storage tank 215 to flow into the drain pipe and be guided to a specific location for discharge, thus avoiding the large amount of water droplets and particulate matter being sucked into the air pump 24 and causing damage to the air pump 24.

[0051] In a further preferred embodiment of the invention, such as Figure 2 , Figure 6 andFigure 7 As shown, the support mechanism 25 includes several spring pieces 252, and several air storage slots 251 are opened on the outer wall of the conveyor belt 21. The air storage slots 251 are located between two corresponding adsorption holes 23. The spring pieces 252 are fixedly installed in the opening of the corresponding air storage slot 251. The spring pieces 252 are arranged in an arc-shaped plate that protrudes outward from the center position of the corresponding air storage slot 251. The air storage slot 251 is filled with gas.

[0052] In this embodiment, when the fish is adsorbed onto the conveyor belt 21, the support of the fish by the spring sheet 252 creates a certain gap between the fish and the conveyor belt 21, allowing gas to flow through the gap between the bottom of the fish and the conveyor belt 21 into the adsorption hole 23, thereby accelerating the rate at which water and particulate impurities from the bottom of the fish flow into the water in the water storage tank 215.

[0053] During the rotation of the conveyor belt 21, when the spring piece 252 moves to the arc position of the stop block 210, due to the mutual contact between the spring piece 252 and the arc surface of the stop block 210, the spring piece 252 is squeezed by the stop block 210 and automatically deforms and retracts into the air storage groove 251, which will not affect the rotation of the conveyor belt 21. After the spring piece 252 moves out of the groove on the right side of the stop block 210, due to the pushing of the gas in the air storage groove 251 and the deformation and reset of the spring piece 252, the middle part of the spring piece 252 automatically moves out of the air storage groove 251, which will not affect the rotation of the conveyor belt 21.

[0054] In a further preferred embodiment of the invention, such as Figure 1 , Figure 10 and Figure 11 As shown, the cleaning component 3 includes a protective cover 31, which is fixedly installed on the top of the outer shell 1. The left end of the protective cover 31 is in contact with the right side of the feed hopper 212. A diversion groove 32 is provided in the inner wall of the protective cover 31. Several sets of exhaust holes 33 are provided on the inner top wall of the protective cover 31. The distance between two adjacent sets of exhaust holes 33 is equal. The distance between two adjacent exhaust holes 33 in each set is equal. Each exhaust hole 33 is inclined.

[0055] In this embodiment, after the fish is moved into the protective cover 31, the gas in the diversion channel 32 is continuously discharged from the exhaust port 33, thereby forming several sets of inclined airflows that blow on the top side of the fish, blowing off the water or fish scales and other debris on the fish, and automatically cleaning the surface of the fish's body.

[0056] It should be noted that if the fish transported above have been gutted, the blood on the fish can be cleaned.

[0057] In a further preferred embodiment of the invention, such as Figure 4 , Figure 5 , Figure 9 and Figure 13As shown, the exhaust mechanism 29 includes a diversion shell 291, which is located on the bottom side of the exhaust ends of several air pumps 24. The exhaust end of each air pump 24 is fixedly inserted through the shell wall of the diversion shell 291. The bottom end of the diversion shell 291 is fixedly inserted through the baffle 26 and connected to the inner wall of the conveyor belt 21. The interior of the diversion shell 291 is connected to the interior of the diversion groove 32 through several connecting pipes 292. A partition 293 is fixedly installed inside the diversion shell 291, and the partition 293 is located on the bottom side of the connecting pipe 292. Several pressure relief valves 294 are fixedly inserted through the partition 293.

[0058] In this embodiment, the gas drawn by the air pump 24 is first injected into the distribution shell 291. Due to the obstruction of the partition 293 and the pressure limiting valve 294, the gas first fills the distribution shell 291 and flows into the distribution groove 32 through the connecting pipe 292. Since the amount of gas discharged from the exhaust port 33 is limited, the gas injected into the distribution groove 32 quickly fills the distribution groove 32 while being discharged from the exhaust ports 33 at some locations. Subsequently, some gas is continuously discharged from several exhaust ports 33. At this time, since the amount of gas discharged from the exhaust ports 33 is limited, the pressure in the distribution shell 291 and the distribution groove 32 continues to rise, which in turn causes the pressure difference between the two ends of the exhaust port 33 to gradually increase, which in turn causes the airflow velocity in the exhaust port 33 to gradually increase until gas flows out of the exhaust port 33. The amount of gas flowing into the diversion tank 32 is equal to the amount of gas flowing into the diversion shell 291. At the same time, as the gas pressure in the diversion shell 291 increases, the pressure difference across the pressure limiting valve 294 also gradually increases. After the pressure difference across the pressure limiting valve reaches the threshold, a small amount of gas in the diversion shell 291 passes through the pressure limiting valve 294 and is discharged from the bottom opening of the diversion shell 291. At this time, the amount of gas discharged from the diversion shell 291 through the connecting pipe 292 and the amount of gas discharged from the diversion shell 291 through the pressure limiting valve 294 are equal to the amount of gas injected into the diversion shell by the air pump 24. Combined with the adhesion of the water in the water storage tank 215 to clean the gas, the top side of the conveyor belt 21 is filled with a large amount of cleaned gas, which prevents the airflow from blowing on the fish and carrying a large amount of dust, thus preventing the fish from being covered with a large amount of dust.

[0059] In a further preferred embodiment of the invention, such as Figure 3 , Figure 4 , Figure 5 and Figure 14 As shown, the debris collection assembly 4 includes a storage box 42. An installation groove 41 is provided at the bottom of the outer shell 1. The storage box 42 is located in the installation groove 41 and is in contact with the inner wall of the installation groove 41. The left end of the storage box 42 extends to the outside of the installation groove 41 and is fixedly connected to the outer shell 1 by bolts. A guide tube 43 is slidably installed in the opening at the right end of the storage box 42. The top end of the guide tube 43 is located directly below the diversion shell 291 and is in contact with the outer wall of the conveyor belt 21. A feed hole 46 is provided at the right end of the top side of the guide tube 43.

[0060] In this embodiment, since the large-volume debris is small in size and light in weight, it is firmly adsorbed on the conveyor belt 21 and moves into the guide pipe 43 through the feed hole 46 as the conveyor belt 21 rotates. At this time, due to the push of the gas flowing out from the bottom opening of the diversion shell 291, the large-volume debris falls directly into the guide pipe 43 and falls into the storage box 42 with the airflow for storage, without the operator having to perform any other operations.

[0061] In a further preferred embodiment of the invention, such as Figure 3 , Figure 4 and Figure 14 As shown, the left end of the baffle 26 is in clearance fit with the corresponding drive roller 221, the right side of the baffle 26 is arc-shaped and contacts the outer peripheral wall of the corresponding drive roller 221, a square hole 44 is opened at the left end of the top side of the storage box 42 corresponding to the left end of the baffle 26, a sieve plate 45 is fixedly installed in the square hole 44, and the outer peripheral wall of the sieve plate 45 is fixedly connected to the inner wall of the storage box 42, and the inner wall of the guide pipe 43 is wavy with ridges.

[0062] In this embodiment, the edge-shaped setting of the inner wall of the feed tube 43 can greatly reduce the contact area between the debris and the feed tube 43, so that the debris will not have a large adhesion force with the inner wall of the feed tube 43, thus avoiding the debris from adhering to the inner wall of the guide tube 28.

[0063] The gas flowing out from the bottom opening of the feed pipe 43 passes through the storage box 42, the holes of the screen plate 45, the square hole 44, and the adsorption hole 23 between the baffle 26 and the drive roller 221, and flows into the space between the conveyor belt 21 and the inner wall of the outer shell 1. This creates a continuous airflow in the storage box 42 towards the screen plate 45. As a result, after the debris in the feed pipe 43 falls into the storage box 42, the airflow pushes the debris a certain distance towards the screen plate 45, thus spreading the large debris in the storage box 42 to a certain extent. This prevents the accumulation of a large amount of large debris at the bottom of the feed pipe 43 from affecting the use of the device. Furthermore, when the large debris moves towards the screen plate 45, the screen plate 45 blocks the large debris from floating out through the rectangular hole.

[0064] Working principle: Before using this improved fish conveyor, the operator first connects the drain pipe to the drain end of the drain valve 214. Then, the operator pours a certain amount of water onto the top side of the conveyor belt 21. The water flows through the suction holes 23 of the conveyor belt 21 and falls onto the guide plate 27. Then, it immediately gathers along the top arc of the guide plate 27 towards the guide tube 28. Finally, it drips through the guide tube 28 into the water storage tank 215 for storage. At this time, the water storage tank 215 stores a specific amount of water, and the water surface in the water storage tank 215 overflows the mesh plate 213.

[0065] When the improved fish conveyor is in use, the driver 222 and the air pump 24 are started first. The started driver 222 drives the drive roller 221 to rotate continuously. Due to the friction between the drive roller 221 and the conveyor belt 21 and the constraint and limitation of the conveyor belt 21 by the guide plate 27 and the baffle 26, the conveyor belt 21 rotates continuously in the top opening of the outer casing 1 along a fixed trajectory.

[0066] It should be noted that during the rotation of the conveyor belt 21, when the spring piece 252 moves to the arc position of the stop block 210, due to the mutual contact between the spring piece 252 and the arc surface of the stop block 210, the spring piece 252 is squeezed by the stop block 210 and automatically deforms and retracts into the air storage groove 251, which will not affect the rotation of the conveyor belt 21. After the spring piece 252 moves out of the groove on the right side of the stop block 210, due to the pushing of the gas in the air storage groove 251 on the spring piece 252 and the deformation and reset of the spring piece 252, the middle part of the spring piece 252 automatically moves out of the air storage groove 251.

[0067] The activated air pump 24 continuously draws gas from the outer casing 1 and injects the gas into the distribution shell 291. Due to the obstruction of the partition 293 and the pressure relief valve 294, the gas first fills the distribution shell 291 and flows into the distribution groove 32 through the connecting pipe 292. Since the amount of gas discharged from the exhaust port 33 is limited, the gas injected into the distribution groove 32 quickly fills the distribution groove 32 while being discharged from the exhaust ports 33 at some locations. Subsequently, some gas is continuously discharged from several exhaust ports 33. At this time, since the amount of gas discharged from the exhaust ports 33 is limited, the pressure in the distribution shell 291 and the distribution groove 32 continues to rise, which in turn causes the pressure difference between the two ends of the exhaust port 33 to gradually increase, which in turn causes the airflow speed in the exhaust port 33 to gradually increase until the amount of gas flowing out of the exhaust port 33 is equal to the amount of gas flowing into the distribution groove 32.

[0068] It should be noted that as the gas pressure inside the aforementioned diversion shell 291 gradually increases, the pressure difference across the pressure limiting valve 294 also gradually increases. After the pressure difference across the pressure limiting valve reaches the threshold, a small amount of gas inside the diversion shell 291 passes through the pressure limiting valve 294 and is discharged from the bottom opening of the diversion shell 291. At this time, the amount of gas discharged from the diversion shell 291 through the connecting pipe 292 and the amount of gas discharged from the diversion shell 291 through the pressure limiting valve 294 are equal to the amount of gas injected into the diversion shell by the air pump 24.

[0069] As the air pump 24 operates, a relatively closed negative pressure cavity is formed between the conveyor belt 21 and the inner wall of the outer shell 1. At this time, due to the blocking of the adsorption holes 23 of the conveyor belt 21 by the drive roller 221, the blocking of the adsorption holes 23 of the conveyor belt 21 by the baffle 26, and the blocking of the adsorption holes 23 on the conveyor belt 21 by the guide plate 27, the gas on the top side of the conveyor belt 21 continuously flows through the adsorption holes 23 on the top side of the conveyor belt 21 into the guide plate 27, and then flows through the conduit 28 into the water in the water storage tank 215. Subsequently, the gas emerges from the water in the water storage tank 215 and flows in from the top opening of the water storage tank 215 to replenish most of the gas lost between the conveyor belt 21 and the inner wall of the outer shell 1.

[0070] When a negative pressure chamber is formed between the conveyor belt 21 and the inner wall of the outer shell 1, the gas discharged from the bottom opening of the diversion shell 291 flows into the storage tank 42 through the corresponding adsorption hole 23 on the conveyor belt 21, and flows out of the storage tank 42 through the square hole 44. Then, it flows into the space between the conveyor belt 21 and the inner wall of the outer shell 1 through the adsorption hole 23 between the baffle 26 and the drive roller 221 to replenish the other part of the gas lost between the conveyor belt 21 and the inner wall of the outer shell 1. The start-up of the above device is completed.

[0071] After the above device is started, the operator feeds fish into the feed hopper 212 in sequence using the conveyor. The fish fed into the top opening of the feed hopper 212 slide along the arc surface inside the top opening of the feed hopper 212, and the angle of the fish is automatically adjusted so that the fish fall into the bottom of the feed hopper 212 in a straight position. It should be noted that a certain amount of flat fish can be stacked at the bottom of the feed hopper 212. When the fish fall onto the conveyor belt 21, due to the fish blocking part of the adsorption holes 23 on the upper part of the conveyor belt 21, the gas flowing into the adsorption holes 23 can exert an adsorption force on the fish, which greatly increases the contact force between the fish and the spring 252. At this time, a certain frictional force is generated between the fish and the spring 252 to overcome the frictional force between the stacked fish. Then, as the conveyor belt 21 rotates, the fish at the bottom of the feed hopper 212 can be pulled out from the bottom opening of the feed hopper 212, so that the fish move towards the pad block 211 in sequence.

[0072] When the fish moves to the area below the vent 33, the water or fish scales and other debris on the fish are blown off by the airflow. The water that slides off the fish follows the airflow through the suction hole 23 and through the conduit 28 into the water in the storage tank 215. When the airflow moves to the position of the mesh plate 213, the airflow is split into multiple small streams that travel through the water in the storage tank 215. At this time, the water or dust and other particulate impurities in the airflow are trapped in the water due to the adhesion of the water in the storage tank 215. Opening the drain valve 214 at regular intervals allows excess sewage in the storage tank 215 to flow into the drain pipe and be discharged to a specific location.

[0073] When the fish moves to the pad 211, due to the inertia of the fish and the mutual resistance between the fish and the left side of the pad 211, the fish body gradually slides onto the pad 211, thereby causing the fish to gradually separate from the conveyor belt 21. The fish is discharged from the discharge end of the outer shell 1 and falls into the feed port of the subsequent equipment or the storage equipment used to store the fish. The large-volume impurities such as fish scales that slide off the fish body or the bottom of the fish are small in size and light in weight, and are firmly adsorbed on the conveyor belt 21. As the conveyor belt 21 rotates, they are moved into the guide pipe 43 through the feed hole 46. At this time, due to the push of the gas flowing out from the bottom opening of the diversion shell 291, the large-volume impurities fall directly into the guide pipe 43 and fall into the storage box 42 for storage with the airflow.

[0074] It should be noted that during the movement of the large-volume debris in the feed tube 43, the surface of the large-volume debris is relatively dry due to the blowing of the airflow, and the contact volume between the large-volume debris and the inner wall of the feed tube 43 is extremely small. Therefore, the large-volume debris will not adhere to the inner wall of the feed tube 43, and thus the large-volume debris will fall directly into the storage box 42 for storage.

[0075] It should be noted that after the large-volume debris in the aforementioned guide pipe 43 falls into the storage box, the airflow blowing the large-volume debris in the storage box 42 can push the large-volume debris a certain distance towards the screen plate 45, thereby spreading the large-volume debris that has fallen into the storage box 42 to a certain extent, avoiding the accumulation of a large amount of large-volume debris at the bottom of the guide pipe 43, which would affect the use of the device. Furthermore, when the large-volume debris moves towards the screen plate 45, the large-volume debris will not float out through the rectangular hole due to the obstruction of the screen plate 45.
