[0022] like Figures 1-5 As shown in the figure, an embodiment of the present invention proposes a mud cleaning device for oil extraction, including a mud cleaning frame 1 and a placement plate 2 disposed at the bottom inner side of the mud cleaning frame 1. The mud cleaning frame 1 is provided with a mud cleaning component 3, which is used to clean the mud on the surface of the oil extraction workpiece, and the angle of the workpiece cleaning surface can be adjusted.

[0023] The mud cleaning assembly 3 includes a drive motor 31, a receiving tank 32, a guide groove 33, a sliding groove 34, a turntable 35, an arc groove 351, a slider 352, a push plate 36, a connecting block 37, a toothed plate 38, a fixing plate 39, a full gear 310, a water sprayer 311, and a cleaning nozzle 312. The drive motor 31 is located on the upper end face of the mud cleaning frame 1.

[0024] The receiving groove 32 is formed inside the upper end face of the mud washing frame 1. The guide groove 33 is formed inside the inner wall of the receiving groove 32. Four guide grooves 33 are arranged in a circumferential array. The sliding groove 34 is formed at the top inner side of the mud washing frame 1. The sliding groove 34 communicates with the guide groove 33 inside the mud washing frame 1. The turntable 35 is rotatably connected to the inner side of the receiving groove 32.

[0025] It should be noted that the output end of the drive motor 31 is connected to the turntable 35 inside the receiving groove 32. The diameter of the turntable 35 is matched with the diameter of the receiving groove 32, which makes the turntable 35 rotate more stably inside the receiving groove 32.

[0026] The arc-shaped groove 351 is formed on the upper end face of the turntable 35. Four arc-shaped grooves 351 are arranged in a circumferential array. The slider 352 is slidably disposed inside the arc-shaped groove 351. The push plate 36 is disposed inside the guide groove 33. One end of the push plate 36 is rotatably connected to the slider 352 inside the arc-shaped groove 351.

[0027] It should be noted that a limiting groove is provided on the arc-shaped groove 351, and the slider 352 is slidably connected in the limiting groove. The cross-sections of both the limiting groove and the slider 352 are I-shaped, which makes the sliding of the slider 352 more stable.

[0028] The connecting block 37 is disposed inside the slide groove 34. One end of the connecting block 37 is connected to the push plate 36 inside the guide groove 33. The toothed plate 38 is disposed on the lower end face of the connecting block 37. Four sets of fixing plates 39 are provided, and the four sets of fixing plates 39 are respectively located on one side of the four slide grooves 34.

[0029] Each set of fixed plates 39 has two, and the full gear 310 is rotatably connected between the two fixed plates 39. The toothed plate 38 meshes with the full gear 310 on one side of the set of fixed plates 39. The water sprayer 311 is rotatably disposed below the full gear 310. The water sprayer 311 is provided with a half gear, which meshes with the full gear 310 disposed above the water sprayer 311. The cleaning nozzle 312 is disposed on the water sprayer 311.

[0030] In this embodiment, the workpiece to be cleaned is first placed on the placement tray 2. Then, multiple cleaning nozzles 312 spray water to clean the workpiece on the placement tray 2, cleaning multiple surfaces of the workpiece on the placement tray 2. When the cleaning nozzles 312 adjust the up and down cleaning angle of the workpiece surface, the drive motor 31 is started. The drive motor 31 drives the turntable 35 to rotate. The rotation of the turntable 35 drives the slider 352 to move along the arc groove 351. The movement of the slider 352 drives the push plate 36 to move. 6 drives the connecting block 37 connected to it to move along the slide groove 34. The connecting block 37 drives the toothed plate 38 to move. The movement of the toothed plate 38 drives the full gear 310 meshing with it to rotate. The full gear 310 drives the water sprayer 311 meshing with it through the half gear to rotate. The rotation of the water sprayer 311 causes the angle of the cleaning nozzle 312 that sprays water to clean the workpiece to change. The change of the water spray angle of the cleaning nozzle 312 causes the cleaning surface of the cleaning nozzle 312 to change, so that the cleaning nozzle 312 can clean different surfaces of the workpiece.

[0031] By setting the mud cleaning component 3, the longitudinal angle of the cleaning nozzle 312 can be adjusted, which can increase the longitudinal cleaning range of the workpiece and thus effectively improve the cleaning effect of mud on the workpiece surface.

[0032] The mud cleaning frame 1 has several water passage holes at its inner bottom. A sewage collection tank 4 is provided on the lower end face of the mud cleaning frame 1. A servo motor 5 is provided on the lower end face of the mud cleaning frame 1. The output end of the servo motor 5 is connected to the placement plate 2. A protective cover 6 is provided on the lower end face of the mud cleaning frame 1. The servo motor 5 is located inside the protective cover 6. A water delivery pipe 7 is connected to the water sprayer 311. One end of the water delivery pipe 7 passes through the inner top of the mud cleaning frame 1.

[0033] The protective cover 6 serves to protect the servo motor 5, thus preventing the wastewater from cleaning the workpiece from coming into contact with the servo motor 5 and affecting its normal operation.

[0034] In this embodiment, when the workpiece is being cleaned by water spraying, the servo motor 5 is started. The servo motor 5 drives the placement plate 2 and the workpiece placed on the placement plate 2 to rotate. The rotating placement plate 2 allows the cleaning nozzle 312 to perform 360-degree spray cleaning within the horizontal spray range of the workpiece.

[0035] Through the linkage mechanism of drive motor 31, turntable 35, slider 352, push plate 36, toothed plate 38, full gear 310, and water sprayer 311, the cleaning nozzle 312 can be dynamically adjusted in the vertical direction. Combined with the horizontal rotation of the placement plate 2 driven by servo motor 5, a three-dimensional cleaning trajectory with full coverage is formed. Compared with the traditional fixed cleaning nozzle 312, it can eliminate more than 30% of the cleaning dead corners on the workpiece surface (such as the root of the thread and the inside of the groove).

[0036] Working principle: First, the workpiece to be cleaned is placed on the placement tray 2. Then, the water delivery pipe 7, the end furthest from the water sprayer 311, is connected to the water pump. The water pump then delivers water from the water source to the water sprayer 311 through the water delivery pipe 7. The water sprayer 311 delivers the water to the cleaning nozzles 312. Multiple cleaning nozzles 312 spray water to clean the workpiece placed on the placement tray 2, cleaning multiple surfaces of the workpiece. During the cleaning process, the servo motor 5 is activated, causing the workpiece on the placement tray 2 to rotate. The rotation of the workpiece allows the cleaning nozzles 312 to thoroughly clean the transverse surface of the workpiece. When the cleaning nozzles 312 adjust the vertical cleaning angle of the workpiece surface, the drive motor 31 is activated, causing the turntable 35 to rotate. The rotation of the turntable 35 causes the slider 352 to move along the arc groove 351. The movement of slider 352 drives push plate 36 to move, push plate 36 drives connecting block 37 connected to it to move along slide groove 34, connecting block 37 drives toothed plate 38 to move, toothed plate 38 drives full gear 310 to rotate, full gear 310 drives water sprayer 311 to rotate through half gear, the rotation of water sprayer 311 causes cleaning nozzle 312 to change the angle of water spraying cleaning of workpiece, the change of water spraying angle of cleaning nozzle 312 causes cleaning nozzle 312 to change the cleaning surface of workpiece, so that cleaning nozzle 312 can clean different surfaces of workpiece; when workpiece is being water sprayed, servo motor 5 is started, servo motor 5 drives placement plate 2 and workpiece placed on placement plate 2 to rotate, the rotating placement plate 2 allows cleaning nozzle 312 to spray cleaning in 360 degrees within the horizontal spray range of workpiece.
