Description

Technical Field

[0001] This utility model relates to the technical field of concrete processing, and in particular to a self-cleaning concrete conveying device. Background Technology

[0002] Concrete conveying equipment is a type of machinery used in construction to transport concrete from the mixing site to the pouring site. Examples include belt conveyors, where a drive unit moves the conveyor belt, and the concrete is placed on the belt and transported to the designated location as the belt moves. Idler rollers are used to support the conveyor belt and the concrete, ensuring the smooth operation of the conveyor belt.

[0003] When transporting concrete, existing belt conveyors are prone to concrete residue buildup on the belts. This residue causes uneven weight distribution, leading to belt misalignment, reduced conveying efficiency, accelerated belt wear, and shortened belt lifespan. If not cleaned promptly, the residual concrete will gradually harden and bond tightly to the belt, requiring significant manpower and time for subsequent cleaning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning concrete conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-cleaning concrete conveying device includes a workbench. One end of the workbench is connected to multiple sets of plates, and every two sets of plates are rotatably connected to rollers. A conveyor belt is fitted onto the outer wall of the two sets of rollers. Multiple sets of frames are connected to the workbench, and one end of each set of frames is connected to a spring. One end of each set of springs is connected to the same brush. One end of the workbench has an opening, and both one and the other end of the workbench are connected to round rods. Two sets of round rods are connected to the same plate, and one end of the plate is connected to a scraper.

[0007] Preferably, one end of the workbench is connected to a box, a drawer is movably inserted through the box, and a bolt is threaded to one end of the box, the bolt being threadedly connected to the drawer.

[0008] Preferably, one end of each of the multiple sets of frame bodies is connected to a block, one end of each brush is connected to multiple sets of rods, multiple sets of springs are respectively sleeved on the outer wall of the corresponding rods, and multiple sets of rods are slidably connected to the corresponding blocks.

[0009] Preferably, each pair of the first plates is connected to a third plate, and each pair of the third plates is connected to multiple fourth plates, with each pair of the fourth plates rotatably connected to a support roller.

[0010] Preferably, each pair of the plates is connected to a baffle.

[0011] Preferably, one end of the bolt is connected to a knob.

[0012] Preferably, the box body has a sliding groove at one end and the other end, and the drawer has a slider at one end and the other end, with the two sets of sliders slidingly connected to the corresponding sliding grooves.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordinated design of the scraper, brush, and spring, when concrete is conveyed via belt conveyor, any remaining concrete clumps on the belt will come into contact with the scraper, which will remove the clumps. Meanwhile, the brush, under the action of the spring, adheres to the belt and removes any remaining residue. This dual cleaning design of the scraper and brush achieves a progressive cleaning process, first breaking down large clumps and then finely cleaning the remaining residue. The two components have clear divisions of labor and work together effectively, improving belt cleaning efficiency, reducing wear from residual concrete, extending belt life, and avoiding the need for manual cleaning of concrete residue after a period of conveying.

[0015] 2. Through the coordination between the opening, drawer, and bolts, the residual concrete cleaned by the brush and scraper will fall into the drawer inside the box through the opening. By turning the bolts, the drawer can be removed and the accumulated concrete inside can be cleaned. This achieves a certain degree of centralized collection of residual concrete and prevents it from scattering and polluting the working environment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A self-cleaning concrete conveying device includes a workbench 1. One end of the workbench 1 is connected to multiple sets of plates 2. Rollers 3 are rotatably connected to every two sets of plates 2. An external device drives the rollers 3 to rotate, which in turn drives a conveyor belt 23 to convey concrete. The conveyor belt 23 is fitted over the outer walls of the two sets of rollers 3. Driven by the rollers 3, the concrete placed on them is conveyed from one location to another, completing the concrete conveying task. Multiple sets of frames 4 are connected to the workbench 1. Each set of frames 4 has a spring 5 connected to one end, and each set of springs 5 ​​has a single brush 6 connected to one end. Utilizing its elasticity, the brush 6 remains in contact with the conveyor belt 23, ensuring that the brush 6 effectively cleans the concrete. To clean the residual concrete on the surface of the conveyor belt 23, the workbench 1 has an opening 9 at one end, which is a channel for the residual concrete cleaned by the scraper 14 and brush 6 to flow downwards, allowing the residual concrete to fall smoothly into the drawer 11 in the box 10 below. Both ends of the workbench 1 are connected to round rods 12, and the two sets of round rods 12 are connected to the same plate 13. One end of the plate 13 is connected to a scraper 14, which comes into contact with any residual concrete clumps when the conveyor belt 23 is running, scraping off the clumps. This is used to clean any large pieces of concrete that may remain on the conveyor belt 23. The dual cleaning design of the brush 6 and scraper 14, to a certain extent, avoids residual concrete on the conveyor belt 23.

[0024] In this embodiment, a box 10 is connected to one end of the workbench 1, and a drawer 11 is movably inserted through the box 10. A bolt 21 is threaded onto one end of the box 10, and the bolt 21 is threaded into the drawer 11. By unscrewing the bolt 21, the drawer 11 can be pulled out to clean the brush 6 and scraper 14. Due to gravity, the concrete accumulated in the drawer 11 falls through the opening 9 and is cleaned, which facilitates the collection and cleaning of concrete to a certain extent. Each of the multiple sets of frame bodies 4 is connected to a block 8 at one end, and the brush 6 is connected to multiple sets of rods 7 at one end. Multiple sets of springs 5 ​​are respectively sleeved on the outer wall of the corresponding rod 7, and the multiple sets of rods 7 are slidably connected to the corresponding blocks 8. The rods 7 and blocks 8 cooperate to guide the movement of the brush 6. Each pair of plates 1-2 is connected to a plate 3-15, and each pair of plates 3-15 is connected to multiple pairs of plates 4-16. Each pair of plates 4-16 is rotatably connected to a support roller 17. When concrete is placed on the conveyor belt 23 for conveying, its weight will cause the conveyor belt 23 to deform to a certain extent. The support roller 17 can distribute this weight to a certain extent, reducing the sagging or excessive local stretching of the conveyor belt 23 due to uneven stress, and ensuring that the conveyor belt 23 maintains stable operation to a certain extent. Each pair of plates 1-2 is connected to a baffle 18, which to a certain extent prevents concrete from slipping off the sides of the conveyor belt 23 during concrete conveying. A knob 22 is connected to one end of the bolt 21, which makes it easier to vibrate the bolt 21. The housing 10 has a sliding groove 19 at one end and a slider 20 at one end and another end of the drawer 11. The two sets of sliders 20 are slidably connected to the corresponding sliding grooves 19, providing guidance for the installation and removal of the drawer 11.

[0025] The working principle of this embodiment is as follows: During use, an external drive device drives the roller 3 to rotate. The roller 3 contacts the conveyor belt 23, and the conveyor belt 23 is driven to circulate by friction. At this time, concrete is placed on the conveyor belt 23. As the conveyor belt 23 continues to move, the concrete is smoothly transported from the starting position to the designated location, completing the basic conveying task. When the conveyor belt 23 carries the concrete, concrete lumps may remain on it. As the conveyor belt 23 runs to the position of the scraper 14, the concrete lumps will come into contact with the scraper 14, and the scraper 14 will scrape off these large concrete lumps, initially cleaning the main residue on the conveyor belt 23. Subsequently, the conveyor belt 23 continues to run under the brush 6. The elasticity of the spring 5 makes the brush 6 adhere to the surface of the conveyor belt 23. The brush 6 can remove the small concrete particles and slurry that remain after the scraper 14 has cleaned. The dual cleaning by the brush 6 and the scraper 14 achieves cleaning of the conveyor belt 23, and to a certain extent, avoids further wear on the conveyor belt 23 caused by residual concrete. The residual concrete scraped off by scraper 14 and brushed off by brush 6 will fall directly into drawer 11 inside the lower box 10 through the opening 9 at one end of the workbench 1 under the influence of gravity. When it is necessary to clean the concrete accumulated in drawer 11, loosen bolt 21 to disengage it from drawer 11, thus removing the restriction on drawer 11. Pull out drawer 11, clean the residual concrete inside, and then push drawer 11 back into its original position along slide 19, tighten bolt 21, and the cleaning operation is completed, which facilitates the cleaning and collection of concrete to a certain extent.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
