[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a cleaning device for soil adhering to a long spiral drill rod includes a support frame 1, a cleaning disc 2, and cleaning teeth 3.

[0018] like Figure 2 As shown, the support frame 1 includes a mounting base 11, a support rod 12, a swing arm 13, and a hydraulic cylinder 14. The mounting base 11 is fixed to the side wall of the drilling rig, and the support rod 12 is horizontally mounted on the mounting base 11. The middle position of the swing arm 13 is rotatably connected to the support rod 12, one end of the hydraulic cylinder 14 is rotatably connected to the mounting base 11, and the piston rod at the other end is rotatably connected to the tail position of the swing arm 13.

[0019] like Figure 2 , Figure 3 As shown, the swing arm 13 includes a fixed arm 15 and a movable arm 16. The fixed arm 15 is rotatably connected to the support rod 12, and a lifting ring 17 is provided on the fixed arm 15 to realize the hoisting and installation of the entire support frame 1. The movable arm 16 is slidably connected to the fixed arm 15, and an electric cylinder 18 for controlling the extension and retraction of the movable arm 16 is provided on the fixed arm 15.

[0020] like Figure 2 As shown, the cleaning disc 2 is horizontally rotatably connected to the front end of the swing arm 13, and the cleaning teeth 3 are evenly arranged around the cleaning disc 2 and are used to embed into the spiral gap on the drill rod.

[0021] When it is necessary to clean the soil adhering to the long spiral drill rod, first fix the mounting base 11 to the side wall of the drilling rig to install and fix the support frame 1. Then, control the hydraulic cylinder 14 to start, so that the hydraulic cylinder 14 pushes the swing arm 13 to rotate. At the same time, use the electric cylinder 18 to control the extension and retraction of the movable arm 16 to adjust the length of the swing arm 13. At this time, observe the position of the cleaning disc 2, so that the cleaning teeth 3 on the cleaning disc 2 are embedded into the spiral gap on the drill rod. Then, use the hydraulic cylinder 14 to control the swing arm 13 to rotate in the opposite direction, so that the cleaning teeth 3 are disengaged from the drill rod, ensuring that the drill rod can be screwed into the ground normally for operation.

[0022] When the drill rod is lifted over the soil, the hydraulic cylinder 14 controls the rotation of the swing arm 13, causing the cleaning teeth 3 to engage in the spiral gaps on the drill rod. The drill rod is then lifted upwards while rotating. During this process, the cleaning teeth 3 remove the adhering soil from the drill rod. Furthermore, as the drill rod is lifted, the cleaning disc 2 rotates automatically, ensuring that at least one cleaning tooth 3 is always positioned within the spiral gaps on the drill rod, automatically cleaning the accumulated soil and improving construction efficiency.

[0023] like Figure 2 , Figure 4 , Figure 5 As shown, the outer wall of the cleaning disc 2 is provided with a ring of evenly distributed dovetail grooves 21, the cleaning teeth 3 are provided with dovetail blocks 31 that slide and embed into the dovetail grooves 21, and the cleaning disc 2 is provided with a locking mechanism 4 for fixing the dovetail blocks 31.

[0024] like Figure 4 , Figure 5 As shown, the locking mechanism 4 includes a locking plate 41, a locking rod 42, and a nut 43. The locking plate 41 is disposed on the cleaning disc 2, and the surface of the cleaning disc 2 is provided with a groove 44 for the locking plate 41 to be inserted. The locking rod 42 is disposed on the locking plate 41 and passes through the cleaning disc 2. The nut 43 is threadedly connected to the locking rod 42 and presses against the back side of the cleaning disc 2.

[0025] When the pitch of the drill pipe is different, select an appropriate number of cleaning teeth 3 according to the length of the pitch, and embed the dovetail block 31 on the cleaning tooth 3 into the dovetail groove 21 on the cleaning disc 2 so that the included angle between two adjacent cleaning teeth 3 is the same, thereby achieving the equidistant arrangement of the cleaning teeth 3.

[0026] Then, the locking plate 41 is embedded in the groove 44 on the cleaning disc 2, and the locking rod 42 passes through the cleaning disc 2. Then, the nut 43 is tightened to fix the locking plate 41, thereby completing the pressing and fixing of multiple dovetail blocks 31 and the installation and fixing of multiple cleaning teeth 3.

[0027] Therefore, by setting detachable cleaning teeth 3, the number and spacing of cleaning teeth 3 can be adjusted according to the pitch of the drill rod to meet the cleaning needs of different drill rods, improve practicality, avoid conflict with the drill rod during operation, and protect the drill rod from being crushed.

[0028] like Figure 4 , Figure 5 As shown, a protective strip 22 is embedded in the dovetail groove 21. The protective strip 22 can be embedded in the dovetail groove 21 when it is not in use to prevent soil from entering the dovetail groove 21 and to ensure convenient replacement of the cleaning tooth 3 in different positions later.

[0029] like Figure 4 , Figure 5 As shown, a threading hole 32 is provided through the dovetail block 31, which enables the unified storage and transportation of multiple cleaning teeth 3, and avoids the loss of cleaning teeth 3.

[0030] like Figure 4 , Figure 5 As shown, the cleaning tooth 3 includes a fixing tube 33, a steel wire rope 34, a clamp 35, an end 36, and a bolt 37. The fixing tube 33 connects to the cleaning disc 2. The steel wire rope 34 consists of two strands. The clamp 35 is fixed to one end of the steel wire rope 34 and is used to insert into the fixing tube 33. The end 36 is fixed to the other end of the steel wire rope 34. The bolt 37 is threadedly connected to the fixing tube 33 and tightens the clamp 35.

[0031] When the cleaning tooth 3 is working, it mainly uses the end 36 to peel off the attached soil. At the tail of the end 36, two steel wire ropes 34 are connected to ensure the strength of the end 36 while giving the end 36 a certain degree of elasticity. Therefore, when the drill rod is lifted, it can avoid rigid contact between the cleaning tooth 3 and the drill rod, thereby preventing the cleaning tooth 3 from damaging the drill rod.

[0032] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
