[0023] Please refer to Figures 1 to 5 As shown, the utility model discloses a breaker 100 for processing the scrapped lining in the underground pipeline, wherein the lining is attached to the original pipeline of the underground pipeline. Since the lining is attached to the original pipeline, even if it is damaged, the lining before being cleaned is still generally tubular. The utility model breaker 100 comprises an outer body 1, an inner core 2, a blade 3, a first oil pipeline 5 and a second oil pipeline 6. The interior of the outer body 1 is hollow, the inner core 2 is installed inside the outer body 1, the blade 3 is spirally fixed on the inner core 2 and protrudes outside the outer body 1, and the first oil pipeline 5 and the second oil pipeline 6 are located outside the outer body 1 and connected to the tail end of the outer body 1. When the breaker 100 of the utility model is in use, the first oil pipeline 5 is set as one of the oil pumping pipe and the oil unloading pipe, and the second oil pipeline 6 is set as the other of the oil pumping pipe and the oil unloading pipe, so that when the outer body 1 moves back and forth in the underground pipeline, the rotation of the inner core 2 can drive the blade 3 to rotate spirally relative to the outer body 1, so as to cut the inner lining.

[0024] Please refer to Figure 2 and Figure 3 The inner core 2 has an outer wall surface facing the rear end of the outer body 1, a first gear 7 is fixedly mounted on the outer wall surface of the inner core 2, the rear end of the outer body 1 has an inner wall surface facing the inner core 2, a second gear 8 is movably mounted on the inner wall surface of the outer body 1, and the first gear 7 is meshed with the second gear 8. The crusher 100 of the utility model is meshed between the first gear 7 and the second gear 8, so under the action of unidirectional oil pressure, the rotation of the second gear 8 drives the rotation of the first gear 7, so that the inner core 2 and the blade 3 mounted on the inner core 2 can rotate in a specific direction.

[0025] Specifically, when the first oil pipeline 5 is an oil pumping pipeline and the second oil pipeline 6 is an oil unloading pipeline, the second gear 8 rotates counterclockwise due to the first direction oil pressure from the first oil pipeline 5 to the second oil pipeline 6, thereby driving the first gear 7 to rotate clockwise and then driving the blade 3 to rotate clockwise through the inner core 2; when the second oil pipeline 6 is an oil pumping pipeline and the first oil pipeline 5 is an oil unloading pipeline, the second gear 8 rotates clockwise due to the second direction oil pressure from the second oil pipeline 6 to the first oil pipeline 5, thereby driving the first gear 7 to rotate counterclockwise and then driving the blade 3 to rotate counterclockwise through the inner core 2. That is to say, the breaker 100 of the utility model moves forward or backward in the liner, and the forward and reverse reciprocating cutting can ensure the cutting effect and also prevent the breaker 100 from being stuck in the liner.

[0026] Please refer to Figure 3 The outer body 1 has a cavity 10, and the cavity 10 is divided into a conical first cavity 101 and a cylindrical second cavity 102 according to the shape. The first cavity 101 is located in front of the second cavity 102 to define the front-to-back direction. The outer body 1 includes a head end 11 close to the first cavity 101 in the front-to-back direction and a tail end 12 close to the second cavity 102 in the front-to-back direction. The first oil pipeline 5 and the second oil pipeline 6 are connected to the tail end 12. The first cavity 101 close to the head end 11 is set to a cone so that the utility model crusher 100 has a guiding effect when entering the liner to reduce resistance; the first oil pipeline 5 and the second oil pipeline 6 are connected to the tail end 12, so that during the use of the utility model crusher 100, the pipelines of the first oil pipeline 5 and the second oil pipeline 6 can be exposed outside the underground pipeline, which is convenient for operation. Because the blade 3 is spirally fixed on the inner core 2 and protrudes outside the outer body 1, it can be understood that the outer body 1 is provided with a slot hole that enables the outer body 1 to be exposed, and the utility model will not repeat it.

[0027] Please refer to Figures 1 to 3 The breaker 100 of the utility model further includes a pull ring 4, which is located outside the cavity 10 and is arranged on the head end 11. The function of the pull ring 4 is: because the outermost side of the outer body 1 is the exposed blade 3, the pull ring 4 can be used to hoist and store the breaker 100 of the utility model during normal storage. When the breaker 100 of the utility model is in use, the pull ring 4 can be used to connect a traction rope, which can assist in dragging during the construction process, so as to facilitate dragging the breaker 100 of the utility model out of the underground pipeline.

[0028] Please refer to Figure 3 and Figure 5The utility model crusher 100 further includes a partition 9, and the cavity 10 is divided into a third cavity 103 and a fourth cavity 104 by the partition 9. The inner core 2 is located in the third cavity 103, the first gear 7 and the second gear 8 are located in the fourth cavity 104, and the first oil pipeline 5 and the second oil pipeline 6 are connected to the fourth cavity 104. Therefore, the fourth cavity 104 on the right side of the partition 9 is used as an oil cavity, and the liquid oil flowing between the first oil pipeline 5 and the second oil pipeline 6 directly exerts a force on the second gear 8 in the oil cavity, that is, the liquid pressure is converted into the power of the first gear 7 and the second gear 8. Therefore, hydraulic oil usually does not enter the third cavity 103 of the utility model crusher 100, which is also beneficial to the protection of the inner core 2 and the blade 3. It should also be noted that the first cavity 101, the second cavity 102, the third cavity 103 and the fourth cavity 104 described here respectively divide the cavity 10 from two different angles. The cavity 10 does not actually have four sub-chambers. Figure 3 It can be seen that the third cavity 103 has overlapping parts with the first cavity 101 and the second cavity 102 ; and the fourth cavity 104 completely belongs to the second cavity 102 .

[0029] For further information, please refer to Figure 3 and Figure 5 , the partition plate 9 is provided with a through hole 90. The crusher 100 of the utility model further comprises a connecting member 70, the connecting member 70 passes through the through hole 90 and fixes the first gear 7 to the inner core 2. Therefore, the function of the connecting member 70 is to ensure that the first gear 7 can transmit power to the inner core 2.

[0030] Please refer to Figures 1 to 4 The tip diameter of the blade 3 gradually increases, so during the rotation of the blade 3, the blade 3 cuts a groove with a regular pitch on the lining, and the groove gradually deepens due to the gradual increase in the tip diameter of the blade 3, thereby chopping the lining. The blade 3 is made of hard alloy steel, which ensures that the blade 3 is sharp and is conducive to cutting.

[0031] The height of the blade 3 beyond the outer body 1 should be greater than the wall thickness of the repaired liner tube. Firstly, it is to avoid friction between the outer body 1 and the liner tube during cutting, which may affect the overall movement of the cutter, i.e., the crusher 100, or even stop it. Secondly, when liner fragments fall, there is enough space to accommodate the liner fragments.

[0032] Also note that please refer to Figure 3The inner core 2 has a main body shape matching the outer body 1. The main body shape matching here means that the inner core 2 also includes a conical part and a cylindrical part extending integrally. The conical part of the inner core 2 is located in the conical first cavity 101, and the cylindrical part of the inner core 2 is located in the cylindrical second cavity 102 and is located on one side of the partition 9.

[0033] The utility model also relates to a cleaning device, comprising a scraper and the above-mentioned breaker 100. The scraper is a powerful scraper, which is used to clean the lining shredded by the blade 3 from the original pipe in the underground pipe from the inside to the outside.

[0034] When the utility model breaker 100 is used, the breaker 100 is placed as a whole in the inner liner of the corresponding size, and the breaker 100 is pushed into the pipe by manpower, and there is an obvious damping feeling, and it is OK to push it. The outer body 1 is fixed as a reference, and moves in a straight line during operation; the inner core 2 is installed inside the outer body 1 and can rotate. When the inner core 2 rotates, the friction between the blade tip 3 and the inner liner converts the spiral action of the inner core 2 into the overall linear motion of the utility model breaker 100. When the utility model breaker 100 is used, the first oil pipeline 5 is set as one of the pumping oil pipeline and the unloading oil pipeline, and the second oil pipeline 6 is set as the other of the pumping oil pipeline and the unloading oil pipeline, so that when the outer body 1 moves forward and backward in the underground pipeline, the rotation of the inner core 2 can drive the blade 3 to rotate spirally relative to the outer body 1, which is used to cut the inner liner. The pumping oil pipeline is switched between the first oil pipeline 5 and the second oil pipeline 6, so that the utility model breaker 100 can be switched between forward and backward, so that the inner liner can be repeatedly cut. The reciprocating cutting can ensure the cutting effect and can also prevent the breaker 100 of the utility model from getting stuck in the underground pipeline. Therefore, the utility model realizes the shredding and cleaning of the liner.

[0035] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
