Description

Technical Field

[0001] This utility model relates to the field of concrete construction equipment technology, specifically to an automatic cleaning device for concrete discharge pipes. Background Technology

[0002] Concrete, often simply called PT, is a general term for engineering composite materials that bind aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement, sand, stone and water in a certain proportion. It is widely used in civil engineering.

[0003] Concrete discharge pipes require manual cleaning after use, but manual cleaning suffers from problems such as incomplete cleaning, low efficiency, and high labor intensity. Furthermore, the long-term accumulation of concrete residue can reduce the pipe's inner diameter, decrease conveying efficiency, and even cause blockages, affecting construction progress and increasing maintenance costs. Therefore, a device capable of automatically cleaning concrete discharge pipes is needed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cleaning device for concrete discharge pipes, so as to solve the problem mentioned in the background art of the inability to automatically clean concrete discharge pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1:

[0023] Please see Figure 1-5 This utility model provides a technical solution: an automatic cleaning device for concrete discharge pipes, comprising: a discharge pipe body 1, a fixing ring 2 fixedly connected to the left side of the surface of the discharge pipe body 1, a servo motor 3 fixedly connected to the top of the inner cavity of the fixing ring 2, a threaded rod 4 fixedly connected to the output shaft of the servo motor 3, a movable plate 5 threadedly connected to the surface of the threaded rod 4, a handle 6 movably connected to the inner cavity of the movable plate 5, both sides of the handle 6 extending to the outer side of the movable plate 5, the right side of the handle 6 connected to the movable plate 5 through a positioning structure, a rotating rod 7 fixedly connected to the left side of the handle 6, the bottom of the rotating rod 7 extending to the inner cavity of the discharge pipe body 1 through a movable groove opened at the top of the discharge pipe body 1, a micro motor 8 fixedly connected to the bottom of the left side of the rotating rod 7, a cleaning plate 9 fixedly connected to the output shaft of the micro motor 8, the surface of the cleaning plate 9 contacting the inner wall of the discharge pipe body 1, and a sealing structure installed in the movable groove opened at the top of the discharge pipe body 1.

[0024] Analysis of the above: After the concrete is discharged from the discharge pipe, the workers first remove the sealing structure to expose the movable groove on the discharge pipe body 1. Then, by using the handle 6, the rotating rod 7 drives the micro motor 8 and the cleaning plate 9 to the corresponding positions. At the same time, the rotating rod 7 corresponds to the inlet and outlet of the movable groove at the top of the discharge pipe body 1. Subsequently, the workers start the servo motor 3 and the micro motor 8. The output shaft of the micro motor 8 drives the cleaning plate 9 to rotate, and the output shaft of the servo motor 3 drives the threaded rod 4 to rotate. While the threaded rod 4 rotates, it drives the movable plate 5 to move. The movable plate 5 drives the rotating rod 7 to move forward. The material is placed into the active trough, and at the same time, the cleaning plate 9 cleans the residue on the inner wall of the discharge pipe body 1. Since the cleaning surface of the cleaning plate 9 is inclined, the cleaned residue is transported to the rear through the inclined surface. After cleaning is completed, the operator starts the micro motor 8 to make its output shaft rotate in the opposite direction, which indirectly drives the cleaning plate 9 to move backward. While moving, the residue is moved out of the discharge pipe body 1. After it is completely removed, the operator can also clean the residue on the cleaning plate 9, which eliminates the need for manual cleaning of the inner wall of the discharge pipe body 1, thus automatically cleaning the concrete discharge pipe.

[0025] Example 2:

[0026] Please see Figure 1-5 This utility model provides a technical solution based on Embodiment 1: the positioning structure includes an L-shaped plate 10, an movable rod 11 is movably connected to the inner cavity of the L-shaped plate 10, both sides of the movable rod 11 extend to the outer side of the L-shaped plate 10, a spring 12 is fixedly connected to the left side of the L-shaped plate 10, a cross block 13 is fixedly connected to the left side of the movable rod 11 and the spring 12, a groove matching the cross block 13 is opened on the throttle 6, and the surface of the movable plate 5 contacts the groove.

[0027] Analysis of the above content: When in use, the operator pinches the right side of the movable rod 11 and moves it to the right. At the same time, the movable rod 11 moves the cross block 13 out of the groove in the handle 6, and compresses the spring 12 (Note: the spring force coefficient of the spring 12 can be set to 20-50N / mm). When the cross block 13 is completely removed from the groove, the operator rotates the cleaning structure to the corresponding position through the handle 6. Then, the operator releases the movable rod 11. At this time, the spring 12 rebounds and moves the cross block 13 back into the groove for positioning.

[0028] Example 3:

[0029] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: two positioning blocks 14 are fixedly connected to the right side of the movable plate 5, one of which is in contact with the throttle 6.

[0030] Analysis of the above content: By setting the positioning block 14 to limit the throttle 6, the throttle 6 can only rotate within a certain angle during the rotation process, so that it can reach the corresponding position more accurately.

[0031] Example 4:

[0032] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: a fixing block 15 is fixedly connected to the surface of the micro motor 8, and the right side of the fixing block 15 is fixedly connected to the rotating rod 7.

[0033] Analysis of the above content: By setting the fixing block 15 to fix and support the micro motor 8, the micro motor 8 will not fall off due to gravity.

[0034] Example 5:

[0035] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: a limiting rod 16 is fixedly connected to the top right side of the fixed ring 2, a limiting block 17 is movably connected to the surface of the limiting rod 16, and the bottom of the limiting block 17 is fixedly connected to the movable plate 5.

[0036] Analysis of the above content: By setting the limit rod 16 and the limit block 17 in cooperation, the threaded rod 4 in the movable plate 5 will not rotate itself when it moves because of the threaded connection.

[0037] Example 6:

[0038] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: a support plate 18 is fixedly connected to the right side of the bottom of the discharge pipe body 1, and the bottom of the support plate 18 is in contact with the ground.

[0039] Analysis of the above content: By setting the support plate 18 to support the discharge pipe body 1, the discharge pipe body 1 will not break due to excessive length or lack of support.

[0040] Example 7:

[0041] Please see Figure 1-5 The present invention provides a technical solution based on Embodiment 1: the sealing structure includes two fixed shells 19, the bottom of the fixed shells 19 is fixedly connected to the discharge pipe body 1, and the two fixed shells 19 are connected to each other by bolts with baffles 20, the bottom of the baffles 20 extending to the movable groove opened at the top of the discharge pipe body 1.

[0042] Analysis of the above content: When the inside of the discharge pipe body 1 does not need to be cleaned, the staff only needs to insert the baffle 20 into the fixed shell 19. At the same time, the height of the baffle 20 is sufficient to block the movable trough, making it like a normal discharge pipe. Then, it is fixed with bolts so that concrete will not leak from the movable trough when the discharge pipe body 1 is in use.
