[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this description, those skilled in the art can make creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This utility model provides a device for cleaning, grading, and drying arrowhead, which solves the technical problems in the prior art. The overall concept is as follows:

[0022] Example 1:

[0023] Please see Figures 1-3 A device for cleaning, grading, and drying arrowhead includes a support frame 1. A cleaning cylinder 5, open at both ends, is rotatably mounted on the top of the support frame 1. The inner wall of the cleaning cylinder 5 has a spiral conveying groove with protrusions. When the cleaning cylinder 5 is driven to rotate by an external power source, the object to be cleaned can be conveyed along the spiral conveying groove from one end of the cleaning cylinder 5 to the other end. Below the opening at the other end of the cleaning cylinder 5, a first support plate 9, a second support plate 10, and a third support plate 11 are arranged sequentially and at intervals away from the cleaning cylinder 5. A power supply device is inserted into the top of the third support plate 11. The height-adjustable insert plate 111 has multiple detachable round tubes 12 spaced apart at the top between the first support plate 9 and the second support plate 10, and at the top between the second support plate 10 and the insert plate 111. The distance between each round tube 12 between the first support plate 9 and the second support plate 10 is smaller than the distance between each round tube 12 between the second support plate 10 and the insert plate 111. A first drying tray 13 is rotatably arranged on the top side of the insert plate 111 away from the second support plate 10. A second drying tray 14 is inclinedly arranged in the middle between the second support plate 10 and the insert plate 111.

[0024] In specific implementation, the gaps between the round pipes 12 between the first support plate 9 and the second support plate 10 are small, which is used for discharging sewage. The round pipes 12 between the second support plate 10 and the third support plate 11 are used for grading and screening the arrowhead. The larger ones enter the first drying tray 13 along the round pipes 12, and the smaller ones fall into the second drying tray 14 from between the round pipes 12. In addition, a vibration motor can be installed on the second support plate 10 to make it easier for the arrowhead to slide and fall off. Protective plates can also be added to the two outermost round pipes 12 to prevent the arrowhead from falling from the sides.

[0025] In specific implementation, connectors 2 are provided on both sides of the top of the support frame 1, connecting seats 3 are provided on the top of the connectors 2, and bearing rings 4 are provided on the top of the connecting seats 3 and are fitted on both sides of the outer wall of the cleaning cylinder 5. Connecting rings 6 are provided on both sides of the outer wall of the cleaning cylinder 5 located inside the bearing rings 4, and the connecting rings 6 are connected to the inner ring of the bearing rings 4. Through the cooperation of connectors 2, connecting seats 3, bearing rings 4 and connecting rings 6, the cleaning cylinder 5 can be supported and its rotation can be facilitated. Connectors 2 and connecting seats 3 can be disassembled and assembled through a bolt and nut structure.

[0026] In practice, the cleaning cylinder 5 is tilted, and connecting frames 7 are provided on both sides of the cleaning cylinder 5. A round shaft 8 is provided between the two connecting frames 7, and the two ends of the round shaft 8 extend out of the connecting frames 7. The external power source of the cleaning cylinder 5 is a manual crank or motor connected to the round shaft 8. The cleaning cylinder 5 can be driven manually or electrically to rotate as needed. Alternatively, a gear ring can be provided in the middle of the outer wall of the cleaning cylinder 5, and a platform can be built on top of the support frame 1 to install a motor. The output end of the motor is connected to a gear that meshes with the gear ring to drive the rotation of the cleaning cylinder 5. In actual use, it can be set reasonably according to the needs.

[0027] In specific implementation, the tops of the first support plate 9, the second support plate 10, and the insert plate 111 are all integrally formed with grooves. Several slots 114 are equidistantly provided in the grooves. A fastener 122 is engaged in the slot 114 corresponding to the round tube 12, and the top of the fastener 122 is rotatably connected to the round tube 12. Through the engagement of the slot 114 and the fastener 122, the round tube 12 can be easily disassembled and assembled, and the gap between each round tube 12 can also be adjusted.

[0028] In specific implementation, both ends of the bottom of the round tube 12 are provided with connecting ears 121. The round tube 12 is rotatably connected to the top of the buckle 122 through the connecting ears 121. Through the rotational cooperation between the connecting ears 121 and the buckle 122, the round tube 12 can be rotated when the height of the insert plate 111 is adjusted, thereby adjusting the tilt angle of the round tube 12.

[0029] In practice, multiple positioning slots 112 are provided at equal intervals on both sides of the insert plate 111, and threaded handles 113 are screwed to the top of both sides of the third support plate 11. The inner end of the threaded handle 113 extends into one of the corresponding positioning slots 112. Through the cooperation of the positioning slots 112 and the threaded handles 113, the insertion plate 111 can be positioned and fixed, which facilitates the height adjustment of the insertion plate 111.

[0030] In specific implementation, the inner sides of the second support plate 10 and the third support plate 11 are both inclinedly provided with connecting short plates 15. The second drying tray 14 is placed on the two connecting short plates 15, and one end of the second drying tray 14 is hook-shaped and hung on the end of the connecting short plate 15. The connecting short plates 15 can facilitate the tilting of the second drying tray 14 between the second support plate 10 and the third support plate 11.

[0031] In practice, a gap is left between the second drying tray 14 and the second support plate 10 and the third support plate 11, so that there is room for movement when the insertion plate 111 adjusts and drives the third support plate 11 to move slightly.

[0032] In specific implementation, a through hole 16 is provided at the bottom of one side of the first support plate 9, and a sewage tank can be placed between the first support plate 9 and the second support plate 10. A clean water tank is placed outside the support frame 1. The sewage tank and the clean water tank are connected by a water pipe extending from the through hole 16 and the support frame 1. The clean water tank is equipped with a filter device and a water pump. The water pump can inject water from the clean water tank into the cleaning cylinder 5 through the water pipe for cleaning.

[0033] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0034] In use, a sewage tank is placed between the first support plate 9 and the second support plate 10, and a clean water tank is placed outside the support frame 1. The sewage tank and the clean water tank are connected by a water pipe extending from the through hole 16 and the support frame 1. The clean water tank is equipped with a filter and a water pump. The water pump injects water from the clean water tank into the cleaning cylinder 5 through the water pipe for cleaning. An external power source drives the cleaning cylinder 5 to rotate. After the arrowhead is poured into the cleaning cylinder 5, as the cleaning cylinder 5 rotates and water is injected, the arrowhead rolls continuously along the spiral groove inside the cleaning cylinder 5 for cleaning, cooperating with the convex... The surface of the arrowhead is repeatedly brought into contact with the tank wall and protrusions to peel off the mud and fuzz attached to it. The washed arrowhead falls into the circular tube 12 between the first support plate 9 and the second support plate 10 and continues to slide down. At the same time, the sewage is discharged along with it. The sewage flows from the circular tube 12 into the sewage tank below for collection. The arrowhead that slides down enters the circular tube 12 between the second support plate 10 and the third support plate 11 for grading and screening. Smaller arrowhead falls from the gaps in the circular tube 12 into the second drying tray 14, while larger arrowhead slides down the circular tube 12 into the first drying tray 13.

[0035] In addition, the spacing between the various round tubes 12 between the second support plate 10 and the third support plate 11 can be adjusted before use. The buckle 122 below the round tube 12 can be pulled out from the slot 114 and inserted into other slots 114. The tilt angle of the round tube 12 at this point can also be adjusted. Before adjustment, loosen the bottom of the third support plate 11 and rotate the threaded handle 113 to separate it from the positioning slot 112. The height of the insert plate 111 can be adjusted. Since the buckle 122 is rotatably connected to the connecting ear 121, the tilt angle of the round tube 12 can be adjusted when the height of the insert plate 111 is adjusted. At the same time, the third support plate 11 will also move slightly during the adjustment process. After the adjustment is completed, the bottom of the third support plate 11 can be tightened again.

[0036] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
