Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete pump truck for building construction that is easy to clean. Background Technology

[0002] Construction is a production activity aimed at meeting the needs of social life and production. It involves using various building materials, construction equipment, and technical means to transform engineering blueprints into actual buildings and structures according to specific design schemes. After prolonged use, concrete pump trucks are prone to concrete residue in their pipes, hoppers, and other components. If not cleaned thoroughly and promptly, this can affect the equipment's performance and lifespan. Easy-to-wash concrete pump trucks can more effectively clean the internal components, reducing concrete residue and hardening, and lowering the probability of equipment failure.

[0003] The most basic function of a concrete pump truck used in construction is to achieve efficient concrete delivery. By pumping, it can transport the mixed concrete along pipelines to the designated construction location. Whether it is the pouring of floors in high-rise buildings or long-distance, high-altitude concrete construction scenarios, it can quickly and stably complete the concrete delivery task. Compared with traditional concrete transportation methods, such as tower crane transportation or manual handling, concrete pump trucks greatly improve the efficiency of concrete delivery and reduce construction time.

[0004] In existing technologies, the filter plates of some concrete pump trucks are connected by bolts and nuts, which requires special tools for disassembly, making them difficult to remove. These difficult-to-remove filter plates are also prone to incomplete cleaning. With repeated use, impurities accumulate on the surface of the filter plates. If they are not removed and cleaned in time, these impurities will gradually accumulate, clogging the pores of the filter plates, increasing water flow resistance, reducing the pumping efficiency, and consequently affecting the overall conveying performance of the concrete pump truck. Therefore, an easily washable concrete pump truck for construction is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-wash concrete pump truck for construction, which aims to improve the problem that the filter plates of some existing concrete pump trucks are difficult to disassemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete pump truck for easy cleaning in construction includes a pump truck, a hopper fixedly connected to the right side of the pump truck, a drive assembly installed at the rear of the hopper, a cleaning assembly installed on the left side of the hopper, a water tank fixedly connected to the left side of the cleaning assembly, a filter plate detachably connected inside the water tank, a square opening inside the filter plate, a rotating plate rotatably connected inside the water tank, a groove inside the rotating plate, a pull rod slidably connected to the inner wall of the groove, a limit plate fixedly connected to one side of the pull rod, a spring fixedly connected to one side of the rotating plate, the limit plate being used to compress the spring via the rotating plate, a tank cover rotatably connected to the top of the water tank, and a material discharge assembly installed on the top of the tank cover.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, the front side of which is fixedly connected to the rear side of the hopper, a rotating rod fixedly connected to the drive end of the motor, a stirring rod fixedly connected to the outside of the rotating rod, and the outside of the rotating rod rotatably connected to the inside of the hopper.

[0010] As a further description of the above technical solution:

[0011] The cleaning assembly includes a first pipe, the right side of which is fixedly connected to the left side of the hopper. A one-way valve is fixedly connected inside the first pipe. A water pump is fixedly connected to the left side of the first pipe. A second pipe is fixedly connected to the left side of the water pump. The left side of the second pipe is fixedly connected to the right side of the water tank.

[0012] As a further description of the above technical solution:

[0013] The feeding assembly includes a fixed box, the bottom of which is fixedly connected to the top of the box cover, a cleaning fluid storage box fixedly connected to the top of the fixed box, a second motor fixedly connected to one inner wall of the fixed box, a rotating plate fixedly connected to the drive end of the second motor, a fixed rod fixedly connected to the left side of the rotating plate, a rotating frame rotatably connected to the top of the box cover, a sliding plate rotatably connected to the top of the rotating frame, and a moving block slidably connected to the inner wall of the fixed box.

[0014] As a further description of the above technical solution:

[0015] A liquid inlet is fixedly connected to the top right side of the tank cover, and a water inlet is fixedly connected to the top left side of the tank cover.

[0018] As a further description of the above technical solution:

[0019] The fixed box is fixedly connected to a limiting rod inside, the movable block is slidably connected to the outside of the limiting rod inside, and the bottom of the movable block is slidably connected to the top of the liquid inlet.

[0020] As a further description of the above technical solution:

[0021] One side of the limiting plate is in contact with one side of the rotating plate, and the outside of the rotating plate is engaged with the inner wall of the square opening.

At this point, the filter plate can be removed from the water tank for cleaning, thus enabling the filter plate in the concrete pump truck to be disassembled. This keeps the filter screen and water pump clean, reduces wear or blockage of internal components due to impurities, significantly extends the service life of the equipment, and reduces the risk of premature replacement due to performance degradation.

[0024] In this invention, the second motor starts and drives the rotating plate to rotate. The fixed rod fixed on the left side of the rotating plate rotates accordingly. The fixed rod contacts the inner wall of the rotating frame and pushes the rotating frame to rotate. The rotating frame drives the sliding plate to slide on the inner wall of the moving block, realizing the quantitative feeding of the cleaning fluid. This ensures that the cleaning fluid used each time just meets the equipment cleaning needs, which not only guarantees the cleaning effect but also reduces the cost of purchasing the cleaning fluid.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figures 2 to 4This utility model provides an embodiment of an easy-to-wash concrete pump truck for construction, comprising a pump truck 1, a hopper 2 fixedly connected to the right side of the pump truck 1, a drive assembly installed at the rear of the hopper 2, a cleaning assembly installed on the left side of the hopper 2, a water tank 10 fixedly connected to the left side of the cleaning assembly, a filter plate 11 detachably connected inside the water tank 10, a square opening 12 formed inside the filter plate 11, a rotating plate 13 rotatably connected inside the water tank 10, a groove 14 formed inside the rotating plate 13, a pull rod 15 slidably connected to the inner wall of the groove 14, the pull rod 15 sliding within the groove 14, driving the rotating plate 13 to rotate, thereby engaging and disengaging the rotating plate 13 from the square opening 12, and a limit plate 16 fixedly connected to one side of the pull rod 15. Pulling the lever 15 moves the limiting plate 16, causing the rotating plate 13 to rotate, thus disassembling the filter plate 11. A spring 17 is fixedly connected to one side of the rotating plate 13. The limiting plate 16 is connected to the lever 15. When the lever 15 is pulled, the limiting plate 16 moves, causing the rotating plate 13 to rotate and compress the spring 17. When the lever 15 is released, the spring 17 releases its elastic potential energy, pushing the limiting plate 16 and the rotating plate 13 to reset, so that the rotating plate 13 automatically engages with the square opening 12, thus automatically fixing the filter plate 11. The top of the water tank 10 is rotatably connected to the tank cover 18. A feeding assembly is installed on the top of the tank cover 18. One side of the limiting plate 16 contacts one side of the rotating plate 13, and the outside of the rotating plate 13 engages with the inner wall of the square opening 12.

[0035] Reference Figure 2 The drive assembly includes a motor 3, the front of which is fixedly connected to the rear of the hopper 2. A rotating rod 4 is fixedly connected to the drive end of the motor 3, and a stirring rod 5 is fixedly connected to the outside of the rotating rod 4. Driven by the rotating rod 4, the stirring rod 5 stirs the concrete in the hopper 2, so that the various components of the concrete are fully mixed and uniform. Its unique shape and distribution can effectively break up concrete lumps, promote the full integration of cement, aggregate, water and other components, and improve the workability and quality of the concrete. The outside of the rotating rod 4 is rotatably connected to the inside of the hopper 2.

[0036] The cleaning assembly includes pipe 6, with its right side fixedly connected to the left side of hopper 2. A one-way valve 7 is fixedly connected inside pipe 6. During the cleaning process, the one-way valve 7 ensures that the cleaning water can only flow from water tank 10 to hopper 2, preventing backflow and contamination of the water in water tank 10. It also ensures the stability and effectiveness of the cleaning process. A water pump 8 is fixedly connected to the left side of pipe 6, and a second pipe 9 is fixedly connected to the left side of water pump 8. The left side of second pipe 9 is fixedly connected to the right side of water tank 10. Water pump 8 draws water from water tank 10 and delivers it to hopper 2 through pipe 6. Water pump 8 provides sufficient impact force to effectively remove residual concrete from hopper 2 and the concrete conveying pipe.

[0037] Reference Figure 2 , Figure 5 and Figure 6 The feeding assembly includes a fixed box 19, the bottom of which is fixedly connected to the top of a box cover 18. A cleaning fluid storage tank 20 is fixedly connected to the top of the fixed box 19. A motor 21 is fixedly connected to one inner wall of the fixed box 19. A rotating plate 22 is fixedly connected to the drive end of the motor 21. A fixed rod 23 is fixedly connected to the left side of the rotating plate 22. A rotating frame 24 is rotatably connected to the top of the box cover 18. A sliding plate 25 is rotatably connected to the top of the rotating frame 24. When the rotating plate 22 rotates, the fixed rod 23 pushes the rotating frame 24 to rotate, converting the rotational motion of the rotating plate 22 into the rotation of the rotating frame 24, thereby driving the sliding plate 25 and the moving block 26 to move, realizing the opening and closing of the cleaning fluid feeding channel. The moving block 26 is slidably connected to the inner wall of the fixed box 19. The motor 21 drives the rotating plate 22 to rotate, controlling the sliding of the moving block 26 to realize the quantitative feeding of the cleaning fluid. When the through hole in the moving block 26 coincides with the inlet 28, the cleaning fluid flows through... The liquid inlet 28 enters the water tank 10; when the motor 21 stops rotating, the moving block 26 resets, closing the channel and realizing the quantitative feeding of the cleaning liquid. The liquid inlet 28 is fixedly connected to the top right side of the tank cover 18, and the water inlet 29 is fixedly connected to the top left side of the tank cover 18. When the water level in the water tank 10 is low, water is injected through the water inlet 29 and mixed with the quantitatively fed cleaning liquid to form a cleaning liquid of appropriate concentration, ensuring that there is a sufficient supply of cleaning liquid for the cleaning work. The outer side of the sliding plate 25 is slidably connected to the inner wall of the moving block 26, and the outer side of the fixed rod 23 is in contact with the inner wall of the rotating frame 24. The inner side of the fixed box 19 is fixedly connected to the limit rod 27, and the inner side of the moving block 26 is slidably connected to the outer side of the limit rod 27. The limit rod 27 ensures that the moving block 26 slides accurately in a straight line in the fixed box 19, preventing the moving block 26 from deviating or shaking, and ensuring the accuracy and stability of the opening and closing of the cleaning liquid feeding channel. The bottom of the moving block 26 is slidably connected to the top of the liquid inlet 28.

[0038] Working principle: After the concrete conveying operation is completed, the pump truck needs to be cleaned. Water in the water tank 10 enters the water pump 8 through pipe 2 9 under the action of the water pump 8, and is then transported to the hopper 2 through pipe 1 6. The one-way valve 7 inside pipe 1 6 can prevent water backflow, ensuring that water can only flow from the water tank 10 to the hopper 2, cleaning the residual concrete and realizing the cleaning of the pump truck. The filter plate 11 inside the water tank 10 plays a filtering role. During the cleaning process, the filter plate 11 can intercept impurities in the water and prevent impurities from clogging the water pump 8 or pipes. When it is necessary to clean the impurities on the filter plate 11, pull the lever 15. The lever 15 drives the limit plate 16 to move. The movement of the limit plate 16 compresses the spring 17 through the rotating plate 13, causing the rotating plate 13 to disengage from the square opening 12. At this time, the filter plate 11 can be removed from the water tank 10 for cleaning. After cleaning, it can be reinstalled, realizing the convenient disassembly and installation of the filter plate 11, which facilitates the maintenance and cleaning of the inside of the water tank 10.

[0039] When motor 21 starts, it drives the rotating plate 22 to rotate. The fixed rod 23 fixed on the left side of the rotating plate 22 rotates accordingly. The fixed rod 23 contacts the inner wall of the rotating frame 24, pushing the rotating frame 24 to rotate. The rotating frame 24 drives the sliding plate 25 to slide on the inner wall of the moving block 26. At the same time, the moving block 26 slides linearly along the inner wall of the fixed box 19 under the restriction of the limiting rod 27. When the through hole in the moving block 26 coincides with the liquid inlet 28, the cleaning liquid enters the water tank 10 through the liquid inlet 28. After motor 21 rotates a certain angle, it stops and closes the channel, realizing the quantitative feeding of the cleaning liquid. By controlling motor 21, the dosage of cleaning liquid entering the water tank 10 can be controlled to meet different cleaning needs and avoid waste of cleaning liquid.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
