Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline dredging, in particular to a bucket structure and a pipeline dredging robot. BACKGROUND

[0002] As a main tool for transporting substances, pipelines are often used for the discharge of liquid substances such as sewage and rainwater. Under long-term use, silt substances often remain on the inner wall of the pipeline. Therefore, in order to ensure the quality of substance transportation of the pipeline, a specific tool is generally used to carry out dredging treatment on the pipeline.

[0003] The traditional pipeline dredging generally adopts the process of first stopping the related equipment, then disassembling the valve or the pipeline, and manually checking to determine the specific position of the foreign matter in the pipeline. However, since most of the pipelines are laid in underground environment, manual operation on the pipeline generally has many inconveniences and low work efficiency. Therefore, the existing pipeline dredging is replaced by using a corresponding pipeline dredging robot.

[0004] The existing pipeline dredging robot is composed of a bucket, an auger, a slurry pump, a driving arm, a walking module, a driving structure and the like. When in use, the pipeline dredging robot enters a pipe culvert by excavating a channel. An operator controls the pipeline dredging robot to walk through a control box. The hydraulic bucket auger at the front end of the robot stirs and crushes the slurry. The slurry pump concentrates the silt to a sewage suction port. The filter device of the bucket, the sewage suction port and the slurry pump performs multi-stage filtration and screening on the slurry. The particles with a diameter less than 25 mm are separated out. The separated silt is sucked into a slurry pipe by a hydraulic booster pump and is transported to a ground cement tank truck for treatment.

[0005] However, the existing pipeline dredging robot has the problem that after each time the robot scoops up a bucket of silt, the upper silt slides down, so that the robot needs to retreat a certain distance before the next time of scooping up silt, so as to completely remove the silt in the pipeline.

[0006] Therefore, the present application provides a bucket structure and a pipeline dredging robot having the same to solve the above technical problems. SUMMARY

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In the first embodiment, refer to Figures 1 to 9 .

[0040] As Figures 1 to 3 , Figure 5 ​​​​​As shown, the present application provides a bucket structure, including a bucket body 1, a screw auger mounting block 11 and a grid net 2 for protecting the screw auger structure are arranged on the inner side of the bucket body 1, a hook-shaped plate 3 arranged at the opening bottom end of the bucket body 1, and a spade mechanism 4 arranged on the bucket body 1, wherein:

[0041] The spade mechanism 4 includes an arc-shaped spade 41 arranged on the outer side of the hook-shaped plate 3 with a concave surface facing upward, an extension plate 42 arranged on the arc-shaped spade 41, a lever pivot 43 arranged on the arc-shaped spade 41 for turning the arc-shaped spade 41 at the opening of the bucket body 1, a plurality of protrusions 45 arranged inside the bucket body 1, and a resilient pushing assembly 48 arranged inside the protrusions 45, one end of the resilient pushing assembly 48 being connected to the extension plate 42 through a first hinge 46, the other end of the resilient pushing assembly 48 being connected to the inside of the protrusions 45 through a second hinge 47, and the inside of the protrusions 45 being connected to the bottom side of the bucket body 1.

[0042] In a specific implementation, since the arc-shaped spade 41 is arranged to rotate at the opening of the bucket body 1 through the lever pivot 43, and the resilient pushing assembly 48 continuously presses downward on the extension plate 42, under normal conditions, the bucket body 1 is always placed on the bottom surface of the pipeline, and the gravity presses the extension plate 42 to make it fit under the bucket body 1, at this time, the arc-shaped spade 41 can be used to shovel the sludge into the bucket body 1 when the bucket body 1 moves normally, when the amount of sludge in the bucket body 1 is too much and needs to be cleaned, the bucket body 1 is moved upward by external control, at this time, the bottom of the extension plate 42 is not forced, one end of the resilient pushing assembly 48 presses the extension plate 42, and can push the arc-shaped spade 41 to turn inside the bucket body 1 when the bucket body 1 moves upward, thereby preventing the sludge on the bucket from sliding off and improving the stability and efficiency of sludge shoveling and cleaning.

[0043] It should be noted that, first, the screw auger structure and the grid net 2 located on the inner side of the bucket body 1 are both existing disclosed structures of the pipeline dredging robot, therefore, the specific operation principle and use method of the screw auger structure and the grid net 2 are not described here, second, the arc-shaped spade 41 is arranged with a sharp front side and a bottom side that fits on the bottom wall of the pipeline, for sending the sludge into the bucket body 1 through the spade body over the hook-shaped plate 3 during movement, and finally, the concave surface of the arc-shaped spade 41 is arranged to face the opening of the hopper body when it is turned over.

[0044] As shown in the accompanying drawings, Figures 2 to 4 The grid net 2 is composed of a plurality of triangular strip blocks 21 with isosceles triangular cross sections, and the side of the grid net 2 opposite to the screw auger structure is arranged as the triangular bottom surface 22 of the triangular strip blocks 21.

[0045] Since the grid net 2 is obtained by using multiple triangular blocks 21 combinations, and since the triangular bottom edge is directed towards the auger structure, the grid net 2 can form a mesh structure that is large in opening towards the outside of the bucket body 1 and small in opening towards the inside of the bucket body 1, and at this time the grid net 2 is arranged sharp towards the outside of the bucket body 1, which can effectively improve the entering efficiency of the sludge when the sludge enters the inside of the bucket body 1, and effectively play a blocking role when the sludge activity leaves the inside of the bucket body 1, which can not only play a role in protecting the internal structure of the bucket body 1 during actual dredging operation, but also effectively improve the dredging efficiency and quality inside the bucket body 1.

[0046] As shown in Figure 7 , the elastic pushing assembly 48 includes a sleeve 481 connected with the first hinge 46, a connecting column 482 arranged in the sleeve 481 and connected with the second hinge 47, a spring 483 arranged in the sleeve 481 for driving the connecting column 482 to extend out of the sleeve 481, a sliding groove 484 arranged on the inner side of the sleeve 481, and a sliding block 485 sliding in the sliding groove 484, the connecting column 482 is connected with the sliding block 485 for limiting sliding in the sleeve 481, and the sleeve 481 is arranged with one end closed.

[0047] In specific implementation, the sliding block 485 and the sliding groove 484 can cooperate to control the connecting column 482 to limit sliding in the sleeve 481, and the connecting column 482 is extruded by the spring 483 to extend out of the opening of the sleeve 481.

[0048] In addition, as shown in Figure 6 , the inner side of the sleeve 481 is sequentially sleeved with at least one group of other sleeves 481, and the sleeves 481 sleeved with each other are provided with springs 483;

[0049] The sliding block 485 is connected with the inner sleeve 481 for limiting the sliding of the inner sleeve 481 in the inside of the outer sleeve 481.

[0050] In specific implementation, the multiple sleeves 481 are controlled to limit telescopic movement by the sliding block 485 and the sliding groove 484, and are always extruded to the extension plate 42 direction by the spring 483.

[0051] It should be noted that the above-mentioned elastic pushing assembly 48 can be regarded as a telescopic rod structure or a multi-section telescopic rod structure which is continuously extruded.

[0052] In addition, as shown in Figure 8 and Figure 9 , the arc-shaped spade 41 is provided with a wing plate 44 on both sides, which can be used for sliding in close contact with the inside of the bucket body 1, and the wing plate 44 is provided with a sharp front side.

[0053] In the implementation, when the arc-shaped spade 41 drives the wing plate 44 to flip towards the opening of the bucket structure, it can be blocked by the grid 2, playing a role in limiting the flipping of the arc-shaped spade 41, preventing the elastic spade 41 from shaking and damaging the elastic pushing assembly 48. At the same time, the wing plate 44 can also shield the bottom end of the opening of the bucket body 1 when the arc-shaped spade 41 flips, preventing the sludge from escaping from the inside of the bucket body 1 when the bucket body 1 moves, and improving the stability and efficiency of sludge cleaning.

[0054] As shown in Figure 3 and Figure 5 , the hook-shaped plate 3 is provided with an arc-shaped groove 31 on the side away from the spade mechanism 4 for increasing the amount of sludge stored, which can increase the amount of sludge carried by the bucket when the sludge is accumulated inside the bucket body 1, so that the bucket can adapt to the complex pipeline environment with more sludge when it is running. At the same time, it can also effectively prevent the sludge from escaping from the inside of the bucket body 1 when the bucket body 1 moves when a certain amount of sludge is stored inside the bucket body 1.

[0055] As shown in Figure 1 , a plurality of driving arms 13 and a pump suction pipe 12 for communicating the inside of the bucket body 1 are installed on the bucket body 1. The plurality of driving arms 13 and the pump suction pipe 12 for communicating the inside of the bucket body 1 installed on the bucket body 1 can be used for the overall movement of the bucket body 1, and the pump suction pipe 12 is used to cooperate with the auger structure to complete the cleaning of the sludge inside the bucket body 1.

[0056] On the basis of the above embodiment, a second embodiment is proposed, which is described in detail in Figures 10 to 12 .

[0057] As shown in Figure 10 and Figure 11 , a pipeline dredging robot includes a robot body 5, a pump suction pipe 12, a driving arm 13, a driving member for controlling the operation of the driving arm 13, and a bucket structure installed on the pump suction pipe 12 and the driving arm 13.

[0058] As shown in Figure 12 , the pump suction pipe 12 and the driving arm 13 are both arranged on the robot body 5 and are operated and controlled by the robot body 5. The driving member can control the bucket structure to move in front of the pipeline travel route of the robot body 5 by controlling the operation of the driving arm 13.

[0059] In addition, the bucket structure is the bucket structure mentioned in the first embodiment.

[0060] In the specific implementation, the pipeline dredging robot moves in the silt pipeline, controls the operation of the driving arm 13 by using the driving member to control the shovel structure to move, carries and collects the silt in the pipeline, and can clean the silt in the pipeline through the auger structure in the shovel structure, and then the self-loading pump body of the robot main body 5 uses the pump suction pipe 12 to clean and recycle the silt.

[0061] It should be noted that the pipeline dredging robot carries and collects the silt in the pipeline and the pump body uses the pump suction pipe 12 to clean and recycle the silt, which are all conventional operations of the existing pipeline dredging robot, so the specific structure and operation principle are not described here.

[0062] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
