[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4 As shown, a crude oil sucker rod deep cleaning and repairing device comprises a shot blasting machine 1, a dust outlet pipe 2 and a dust collecting bag 3 which are known to be installed on the shot blasting machine 1, a housing 4 is connected to the end of the dust outlet pipe 2, two symmetrically arranged filter plates 9 are rotatably connected in the housing 4, a spring shaft 10 is fixedly connected to the bottom edge of the filter plate 9 near the middle, the two ends of the spring shaft 10 are rotatably connected to the inner wall of the housing 4 through a turbine spring, and the inner wall of the housing 4 extends inwardly to have a protrusion for supporting the opposite sides of the two filter plates 9, as shown in FIG. Figure 4 As shown, when the connecting pipe 15 is not installed on the housing 4, that is, the dust bag 3 is in a removed state, the two filter plates 9 are kept in a horizontal state under the elastic action of the turbine spring and are completely attached to the inner wall of the housing 4. Therefore, the two filter plates 9 can filter the debris and dust in the air blown out of the dust outlet pipe 2, that is, the debris and dust are temporarily stored in the housing 4:

[0024] In addition, a pusher 11 is slidably connected inside the shell 4 for pushing the two filter plates 9 to open. A limit block 12 that penetrates the pusher 11 is fixedly connected to the inner wall of the shell 4, and a part of the pusher 11 is sleeved on the limit block 12. As shown in the figure, with the auxiliary action of the limit block 12, it is ensured that the pusher 11 can only move along the height direction of the shell 4, and the contact side of the pusher 11 with the filter plate 9 is V-shaped. Therefore, when the pusher 11 moves toward the filter plate 9 until it contacts the contact edges of the two filter plates 9, the two filter plates 9 overcome the elastic force of the turbine spring under the pushing action of the pusher 11 and rotate to an inclined state. At this time, the airflow blown out of the dust outlet pipe 2 does not pass through the filtration of the filter plate 9 but is directly blown out from the gap between the filter plate 9 and the shell 4. At the same time, the debris and dust filtered on the surface of the filter plate 9 can be blown clean:

[0025] A connecting tube 15 is installed at the bag opening of the dust bag 3. The connecting tube 15 is sleeved with the bottom of the shell 4, and a push rod 13 for pushing the push member 11 is fixedly connected inside the connecting tube 15. In order to force the push member 11 to move toward the filter plate 9, the connecting tube 15 is installed at the bag opening of the dust bag 3, and then the connecting tube 15 is sleeved on the bottom end of the shell 4 and moves toward the filter plate 9. When the connecting tube 15 moves, it drives the internal push rod 13 to move, and the push rod 13 contacts and pushes the push member 11 to move toward the filter plate 9.

[0026] In order to facilitate the installation of the dust bag 3, it is further discussed that: the outer wall of the connecting tube 15 is threadedly connected with a threaded ring 14 for pressing the bag mouth of the dust bag 3, and the bottom edge of the threaded ring 14 is horn-shaped. The body of the shot blasting machine 1 is located at the position of the shell 4 and is fixedly connected with a guide rail 6. A U-shaped block 8 that is clamped outside the connecting tube 15 is inserted on the guide rail 6, and a magnetic ring 16 that is magnetically attracted to the side wall of the U-shaped block 8 is fixedly connected to the top edge of the outer wall of the connecting tube 15. An electric telescopic rod 7 for driving the U-shaped block 8 to rise and fall is fixedly connected to the guide rail 6, and the bag mouth of the dust bag 3 is set on After the bottom edge of the outer wall of the connecting tube 15 is reached, the threaded ring 14 is lowered by rotating the threaded ring 14, and the trumpet-shaped part at the bottom of the threaded ring 14 is used to press the bag opening of the dust bag 3. In addition, the guide rail 6 is provided to fix the relative position of the connecting tube 15 and the U-shaped block 8 by magnetic attraction of the magnetic ring 16 and the U-shaped block 8 after the dust bag 3 and the connecting tube 15 are assembled, so that the connecting tube 15 is aligned with the bottom port of the shell 4, so that it is convenient to extend the electric telescopic rod 7 to realize that the U-shaped block 8 drives the connecting tube 15 to rise to the bottom end of the shell 4.

[0027] In order to be suitable for sucker rods of different diameters, it is further discussed that: a plurality of adjustment rings 5 ​​are provided at the inlet and outlet of the shot blasting machine 1, two adjacent adjustment rings 5 ​​are sleeved, and the outer wall of the inner adjustment ring 5 is threadedly connected with the inner wall of the outer adjustment ring 5, and the diameters of the plurality of adjustment rings 5 ​​are fixed. Therefore, when processing the sucker rod, it is only necessary to take out the plurality of adjustment rings 5 ​​on the inner side of the adjustment ring 5 corresponding to the diameter of the sucker rod, so as to ensure that the steel shot, debris and dust in the shot blasting machine 1 will not be ejected from the inlet and outlet of the shot blasting machine 1.

[0028] Working principle: when replacing the dust bag 3, the electric telescopic rod 7 contracts to realize the U-shaped block 8 driving the connecting pipe 15 to move away from the filter plate 9, and the movement of the connecting pipe 15 will drive the push rod 13 to move, so that the push rod 13 loses the pushing effect on the pushing member 11, that is, at this time the pushing member 11 will not generate a thrust on the filter plate 9, so under the elastic force of the turbine spring, the spring shaft 10 will drive the filter plate 9 to generate a downward thrust on the pushing member 11, so that the pushing member 11 drops until the filter plate 9 is in a horizontal state, and the two filter plates 9 in a horizontal state and aligned are used to filter the debris and dust in the airflow blown out of the dust outlet pipe 2, and at this time a part of the connecting pipe 15 is still sleeved on the bottom end of the shell 4, so it is convenient to directly remove the connecting pipe 15 and the dust bag 3, and then clean the debris and dust collected in the dust bag 3, and then reinstall it.

[0029] The wiring diagram of the shot blasting machine 1 and the electric telescopic rod 7 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the shot blasting machine 1 and the electric telescopic rod 7 are not explained in detail.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
