Description

Technical Field

[0001] This utility model relates to the field of waste barrel cleaning technology, specifically a device for cleaning and removing stubborn pollutants from the inner wall of waste barrels. Background Technology

[0002] Used drums refer to various drum-shaped containers that are no longer used for their original purpose due to reasons such as being used up, damaged, or expired. They include metal drums (such as iron drums and steel drums), plastic drums (such as HDPE drums and PP drums), wooden drums, and composite material drums.

[0003] The prior art discloses a reusable steel drum inner wall cleaning device (publication number CN215656920U), comprising a housing, a fixed rod slidably connected to the housing, a cleaning shovel slidably inserted into the fixed rod, and a bolt threadedly connecting the cleaning shovel and the fixed rod. This invention, by turning on the external power switch of the motor, causes the motor to drive a cylindrical disc to rotate clockwise, causing the fixed block to rotate clockwise and push the fixed rod upwards. As the fixed block continues to rotate, it pushes the fixed rod downwards, repeating this process. This causes the fixed rod to slide up and down repeatedly within the housing, driving the cleaning shovel to move up and down repeatedly. By moving the cleaning shovel and contacting the inner wall of the steel drum, the cleaning shovel, during its up-and-down movement, comes into contact with hard objects adhering to the inner wall of the drum, removing these hard objects and facilitating cleaning of the drum wall. The motor-driven cleaning shovel effectively removes hard objects, providing greater cleaning power and saving effort for the user, thus facilitating the removal of hard objects from the drum wall.

[0004] The aforementioned housing has a sliding connection with a fixing rod. Replacing the fixing rod requires cutting the entire housing, which can easily damage the fixing rod. It requires delicate operation, making the replacement of the fixing rod quite troublesome and time-consuming. Utility Model Content

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.

[0026] Please see Figure 1-4 The present invention provides the following technical solution:

[0027] A device for cleaning and removing stubborn pollutants from the inner wall of a waste bin includes a connecting device 1 and a connecting handle 4. The bottom of the connecting device 1 is threadedly connected to a connector 3, and a cleaning roller 2 is fixedly connected to the bottom surface of the connector 3. The connecting handle 4 is installed on the top surface of the connecting device 1.

[0028] The connecting device 1 includes a drive motor 11, a rotating rod 12, and a clamping assembly 13. The drive motor 11 is mounted on the top surface of the clamping assembly 13, the rotating rod 12 is mounted on the bottom surface of the rotor of the drive motor 11, and the connecting piece 3 is threadedly connected to the bottom surface of the rotating rod 12, so that the connecting piece 3 and the cleaning roller body 2 can be disassembled and replaced. Different materials of cleaning roller body 2 can be used according to the different stains on the inner wall surface of the waste barrel.

[0029] The clamping assembly 13 includes a limiting unit and a carrying unit, which are arranged from bottom to top.

[0030] The support unit includes a support frame 136, a drive motor 11 mounted at the bottom of the support frame 136, and a connecting handle 4 mounted on the top surface of the support frame 136. The support frame 136 can determine the position of the drive motor 11 and protect the safety of the drive motor 11. A limit cover plate 137 is fixedly connected to the bottom surface of the support frame 136. The limit cover plate 137 is bolted to the inside of the connecting block 138. The rotating rod 12 is movably connected to the inner wall surface of the limit cover plate 137 and the inner wall surface of the connecting block 138. The limit cover plate 137 and the connecting block 138 can clamp and fix the rotating rod 12, which can maintain the stability of the rotating rod 12.

[0031] The limiting unit includes a clamping frame 131, a connecting frame 133 slidably connected to the bottom of the clamping frame 131, a threaded rod 134 fixedly connected to the top surface of the clamping frame 131, the clamping frame 131 movably connected to the bottom surface of the bearing frame 136, the threaded rod 134 being inserted into the bottom of the bearing frame 136, and the bearing frame 136 and the clamping frame 131 being locked and fixed together by the threaded rod 134, thereby allowing the threaded rod 134 to be disassembled and replaced. A threaded rod 132 is fixedly connected to the outward surface of the connecting frame 133, and the threaded rod 132 is slidably connected to the clamping frame 131. On the inner wall surface of the threaded rod 132, a nut is threadedly connected to the surface of the threaded rod 132. The nut can be rotated on the surface of the threaded rod 132 to lock and fix the clamping frame 131 and the connecting frame 133 together. At the same time, it is convenient to disassemble and replace the connecting frame 133. The connecting frame 133 is movably connected to the surface of the rotating rod 12, and the clamping frame 131 is movably connected to the top of the connector 3. The connecting frame 133 and the clamping frame 131 can clamp and fix the connector 3 and the rotating rod 12 together, which can protect the stability of the connector 3 and the rotating rod 12. A threaded rod 135 is inserted into the inward end of the connecting frame 133.

[0032] When in use, rotating the bolt loosens the bolt from the rotating rod 12 and the connecting piece 3, causing the rotating rod 12 and the connecting piece 3 to separate.

[0033] Rotating the bolt causes it to disengage from the limiting cover plate 137 and the connecting block 138, loosening the connection between the limiting cover plate 137 and the connecting block 138.

[0034] Rotating the threaded rod 134 causes the surface of the threaded rod 134 to rotate the nut, thus loosening the connection between the clamping frame 131 and the bearing frame 136.

[0035] At this time, the clamping frame 131 is pulled down, and the clamping frame 131 can drive the threaded rod 134 to move down. The threaded rod 134 disengages from the bearing frame 136. At the same time, the clamping frame 131 can drive the connecting frame 133 to move down, and the connecting frame 133 can slide on the surface of the rotating rod 12.

[0036] When the clamping frame 131 moves downward, it can push the connector 3 downward, thereby allowing the connector 3 and the cleaning roller body 2 to be disassembled and replaced, so that cleaning roller bodies 2 of different materials and specifications can be used.

[0037] Pour clean water and medicine onto the inner surface of the waste barrel. The mixture of medicines will soak and disinfect the stubborn contaminants on the inner surface of the waste barrel, loosening the connection between the stubborn contaminants and the waste barrel.

[0038] Hold the middle position of the connecting handle 4 and push the connecting handle 4 downward. The connecting handle 4 can push the support frame 136 to move, and the support frame 136 can push the drive motor 11 and the rotating rod 12 downward. The position of the rotating rod 12 can be adjusted.

[0039] Start the drive motor 11. The rotor of the drive motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 can drive the connecting piece 3 to rotate, which can drive the cleaning roller 2 to rotate, so that the cleaning roller 2 can clean the stubborn pollutants on the inner wall surface of the waste barrel.

[0040] The clamping frame 131 and the connecting frame 133 can clamp and fix the rotating rod 12 and the connecting piece 3, which can maintain the stability of the connecting piece 3 and the rotating rod 12 and increase the stability of the cleaning roller body 2.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
