Description

Technical Field

[0001] The present invention relates to an article for daily use, specifically a drum-type sewer cleaner using pipeline cleaning. Through a unique internal structure design, it can avoid the problem of the soft shaft knotting. Background Art

[0002] The drum-type sewer cleaner belongs to a special tool for pipeline cleaning. The current drum-type sewer cleaner mainly designs components such as a bracket, a motor, a belt, a soft shaft box, a soft shaft, and a lining. The motor drives the belt sleeved on the soft shaft box to rotate, thereby driving the soft shaft box and the soft shaft to rotate and move forward and backward. There is a guide tube inside the soft shaft box. When the soft shaft box rotates, it synchronously drives the guide tube to rotate. This guide tube has the function of making the soft shaft move horizontally forward and backward, that is, moving forward and backward, so as to realize the cleaning work of the soft shaft on the pipeline. Since the soft shaft is wound in circles inside the soft shaft box, there is often a problem that the soft shaft knots inside the soft shaft box.

[0003] In order to fix the guide tube, the current drum-type sewer cleaner generally designs structures such as a movable disk or a lining. Among them, the guide tube is designed inside the movable disk, and the guide tube is designed outside the lining. In the way of arranging the guide tube inside the movable disk, since a bearing needs to be installed between the guide tube and the rotating box, there is inevitably a gap between the movable disk and the inner wall of the soft shaft box, so there is a space for the soft shaft to knot at this position. In the way of arranging the guide tube outside the lining, since there is a larger gap between the lining and the inner wall of the soft shaft box, it is more likely that the soft shaft knots at this position. Therefore, in order to facilitate the use of the drum-type sewer cleaner, the above knotting problem needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-knotting drum-type sewer cleaner, and the technical problem to be solved is: how to avoid the soft shaft knotting inside the soft shaft box.

[0005] An anti-knotting drum-type sewer cleaner is designed with a soft shaft box, a fixed sleeve, a guide tube, a rotating bushing, a lining, and a fixed disk; the inside of the soft shaft box is hollow and has two openings. A fixed sleeve is fixed at one of the openings. The outer contour of the fixed sleeve covers the space between the soft shaft box and the rotating bushing and is fixed to the soft shaft box, so that the space between the rotating bushing and the soft shaft box is filled; the inside of the fixed sleeve is hollow to facilitate one side of the guide tube to penetrate through; the rotating bushing is between the fixed sleeve and the lining, and the rotating bushing is only axially connected to one side of the lining. The rotating bushing has a groove for placing the other side of the guide tube so that the guide tube is kept in linkage with the rotating bushing. The other end of the lining is fixed on the fixed disk, and the fixed disk is fixed to the other opening of the soft shaft box.

[0006] A hollow end cap is fixed on the fixing sleeve. The guiding tube penetrates through the fixing sleeve, and the end cap is axially connected to the guiding tube through a bearing, so that the fixing position of the guiding tube is transferred from the inside of the flexible shaft box to the outside of the flexible shaft box.

[0007] The whole lining fills the space between the rotating bush and the fixing disc or the flexible shaft box.

[0008] The lining has a protruding part facing the direction of the rotating lining. A bearing is arranged on the protruding part, and the rotating lining is axially connected to the protruding part of the lining through the bearing, so that the rotating bush is supported by the lining.

[0009] The fixing sleeve has a plurality of screw holes, and the flexible shaft box also has a plurality of screw holes at corresponding positions. The end cap also has screw holes at corresponding positions. The end cap, the fixing sleeve and the flexible shaft box are fixed together by screws and screw holes.

[0010] The end cap is a conical structure with flat tops at the upper and lower parts, and its interior is hollow.

[0011] The guiding tube is arc-shaped and is driven to rotate by the flexible shaft in the flexible shaft box or the guiding tube. A fixing ring is fixed at the position of the end cap of the guiding tube. A screw or a fixing pin passes through the fixing ring and the end of the guiding tube and is pressed together with the flexible shaft, so as to flexibly fix the flexible shaft.

[0012] The flexible shaft box has one or more hollow holes on its outer side wall. The two openings of the flexible shaft box are arranged oppositely.

[0013] The fixing disc has a plurality of disc claws, and screws are installed on the disc claws to fix the flexible shaft box and the lining.

[0014] The number of the disc claws is 6-8, and they have mounting positions along different inner diameters, so as to fix the disc claws to the flexible shaft box and the lining respectively.

[0015] The beneficial effects of the present invention are as follows: In this case, a fixing sleeve, a rotating bush and a lining are installed inside the flexible shaft box. The above components as a whole fill most of the internal space of the flexible shaft box, avoiding the knotting problem that may be caused by the flexible shaft skipping a certain component during use; by separately designing the rotating bush, the rotating bush is fixed and supported through a bearing on the lining, and the resistance during work is smaller. At the same time, it is driven to rotate by the guiding tube and does not directly contact the fixing sleeve, so the rotation will not be stuck and the rotation is easier. Thus, it is changed from the original static state to the simulated rotating state of the guiding tube and the flexible shaft, so as to be close to keeping in sync with the flexible shaft, and thus the knotting problem is solved.

[0017] Please refer to Figures 1 to 11, A knot - proof drum - type drain cleaner in the figure is designed with components such as a motor 10, a bracket 11, a flexible shaft box 7, a fixed sleeve 3, a guide tube 1, a rotating bushing 4, an inner lining 5, a fixed disk 6, an end cap 2, etc.; among them, the bracket 11 supports other components. The motor 10 drives the flexible shaft box 7 to rotate through a belt. The flexible shaft box 7 then drives the fixed sleeve 3, the fixed disk 6, and the flexible shaft 8 to rotate. The fixed sleeve 3 together with the end cap 2 wraps one end of the guide tube 1 inside it. Due to the drive of the flexible shaft 8, the guide tube 1 will drive the rotating bushing 4 to rotate during the rotation process. The inner lining 5 supports the rotating bushing 4 through a bearing 9 to ensure the flexible rotation of the rotating bushing 4. The fixed disk 6 fixes the inner lining 5. The core design of this case is the independent separation design of the rotating bushing 4 led out by the flexible shaft 8. It adopts a very flexible and non - jamming assembly method with other components, without affecting its rotation. At the same time, the overall outer contour of the fixed sleeve 3 covers the space between the flexible shaft box 7 and the rotating bushing 4 and is fixed to the flexible shaft box 7. Moreover, the rotating bushing 4 is fixed and supported in the front - and - back positions through the inner lining 5 and the fixed sleeve 3, thus avoiding the knotting problem of the flexible shaft 8. It should be noted that the above components can also be optimized and expanded in terms of design factors such as shape, structure, quantity, position, etc. according to needs.

[0018] As shown in the figure, the flexible shaft box 7 in the figure is an overall hollow cylindrical structure. Its top and bottom positions in the figure are penetrated to form two symmetrical openings 72. One opening 72 is convenient for installing the fixed sleeve 3 and the end cap 2, and the other opening 72 is convenient for installing the fixed disk 6. Like the existing flexible shaft box 7, two symmetrical hollow holes 71 are designed on the outer side wall of the top of the flexible shaft box 7. The shape, quantity, and position of the above hollow holes 71 can be adjusted according to needs.

[0019] As shown in the figure, the end cap 2 in the figure is an overall conical structure with flat tops at the top and bottom. Its interior is hollow to facilitate the penetration of one end of the guide tube 1. A bearing 9 is designed at the above penetration position so that the end cap 2 and the guide tube 1 can maintain relative rotation and fixation.

[0020] As shown in the figure, the fixed sleeve 3 in the figure is an overall disk - like hollow structure. It is designed with a plurality of screw holes. Screw holes are also designed at the corresponding positions on the top wall of the top of the flexible shaft box 7 and the side wall of the end cap 2. In this way, these components can be fixed to each other through screws and screw holes. The outer diameter of the fixed sleeve 3 is kept corresponding to the outer diameter of the rotating inner lining 5 and is slightly larger than the diameter of the opening 72 of the flexible shaft box 7 at this position, so as to fill the longitudinal space between the opening 72 of the flexible shaft box 7 and the rotating bushing 4. This longitudinal space is also the space where the flexible shaft 8 is prone to knotting.

[0021] As shown in the figure, the guiding tube 1 in the figure is integrally of an arc-shaped structure. The guiding tube 1 can adopt an existing shape structure or be further optimized. The port inside the flexible shaft box 7 can be flared, and it is driven by the flexible shaft 8 to rotate. After the flexible shaft 8 is stored when the dredger is not in use, in order to fix the flexible shaft 8, a fixing ring 13 can be installed at the outer end of the guiding tube 1. In this way, a screw or a pin passes through the fixing ring 13 and the guiding tube 1 to squeeze together with the flexible shaft 8 inside the guiding tube 1 to prevent the flexible shaft 8 from running.

[0022] As shown in the figure, the rotating bushing 4 in the figure is integrally of a structure similar to a round cake with a certain thickness. It is located between the fixed sleeve 3 and the inner lining 5. The rotating bushing 4 has a central hole inside for placing the bearing 9 and is axially connected to the inner lining 5, and a groove-like channel structure is formed by horizontally extending from the central hole to the side wall to facilitate placing the middle and lower parts of the guiding tube 1. In this way, the linkage between the guiding tube 1 and the rotating bushing 4 can be ensured, that is, the guiding tube 1 drives the rotating bushing 4 to rotate.

[0023] As shown in the figure, the inner lining 5 in the figure is integrally of a structure similar to a cylinder. The overall thickness of the inner lining 5 can fill the space between the rotating bushing 4 and the fixed disk 6 or the flexible shaft box 7. In this way, another longitudinally filled space can also prevent the flexible shaft 8 from knotting. A protruding part 51 structure with a certain inner diameter extends from the central position of the inner lining 5 towards the rotating bushing 4. A bearing 9 can be placed at the position of the protruding part 51. In this way, the rotating inner lining 5 is axially connected to the cover protruding part 51 through the bearing 9. In this way, on the one hand, the rotating bushing 4 is supported and fixed by the inner lining 5, and on the other hand, the rotating bushing 4 can rotate more flexibly without jamming problems, reducing the resistance when the flexible shaft 8 works.

[0024] As shown in the figure, the fixed disk 6 in the figure is installed on the inner lining 5 and remains opposite to the rotating bushing 4. The fixed disk 6 is integrally of a structure similar to a divergent disk, that is, it has a plurality of disk claws 61, such as 6 - 8 disk claws 61 are designed. By designing the disk claws 61, the disk claws 61 can fix the flexible shaft box 7 and the inner lining 5 through screws in this way, so as to maintain the linkage of the fixed disk 6, the inner lining 5, and the flexible shaft box 7. The installation positions of the above-mentioned screws are at different positions, that is, installation positions are designed at different inner diameters of the disk claws 61, which is convenient for the installation between various components. The above-mentioned fixed disk 6 is sleeved on a cylindrical rod 12 in the existing manner, and the function of the cylindrical rod 12 can refer to the prior art.

[0025] As shown in the figure, the flexible shaft 8 of this embodiment is an existing component. When the flexible shaft box 7 rotates forward, it rotates and conveys towards the front end of the dredger to complete the pipeline cleaning work. When the flexible shaft box 7 rotates backward, it retracts into the flexible shaft box 7. When the above flexible shaft 8 is horizontally conveyed, it will drive the guide tube 1 to rotate, and then drive the rotating bushing 4 to rotate. The specific cooperation structure between the above flexible shaft 8 and the flexible shaft box 7 can refer to the prior art.
