Description

Technical Field

[0001] The present invention relates to the technical field of construction waste treatment, and more specifically, to a construction waste recycling device. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other waste generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. If construction waste is not handled in a timely manner, it will cause a certain degree of pollution to the ground, thus causing a certain impact on the environment.

[0003] The existing construction waste treatment device does not have a circulation structure, and it is difficult to completely decompose the construction waste in a single treatment, thereby reducing the work quality; it does not have a good screening and classification structure, and the staff needs to manually sort after the treatment is completed, which not only increases the workload of the staff, but also reduces the work speed.

[0004] After searching, the Chinese patent with announcement number CN113600323A discloses a construction waste recycling and processing device. The invention adopts the combination of different devices through the setting of a workbench, a conveyor belt and a collection box, and can first crush, transport, classify, collect and screen the construction waste. The combination of the fixed frame, crushing roller and battery box can crush the construction waste. The combination of the fixed seat, drive motor, cam, transmission rod and push plate can push the construction waste to the limiting slide and slide it to the surface of the conveyor belt. The staff can then pour the garbage in the collection box onto the surface of the workbench for recycling, thereby greatly improving the processing quality. The combination of the universal wheel and the push handle can facilitate the staff to quickly move the collection box.

[0005] However, when the above-mentioned processing device is actually used, when processing construction waste, some used boards will appear in the construction waste, some of which need to be processed to make them available for secondary use. At the same time, in the process of processing construction waste, some dust will be released into the air, which will pollute the environment and affect the health of the workers. Summary of the invention

[0006] In order to overcome the above defects of the prior art, the present invention provides a construction waste recycling device to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions: The construction waste recycling device comprises an operating table, a cutting machine body is fixedly connected to the outside of the operating table, a fixing plate is fixedly connected to one side of the operating table, and a grinding and cleaning mechanism is arranged on the lower surface of the fixing plate; the grinding and cleaning mechanism comprises a first motor, the top of the first motor is fixedly connected to the lower surface of the fixing plate, the output end of the first motor is fixedly connected to a first rotating shaft, a driving gear is fixedly connected to the first rotating shaft, a transmission gear is meshed at the bottom of the driving gear, a limiting rod is movably connected inside the transmission gear, and the limiting rod is fixedly connected to the side of the operating table, a driven gear is meshed at the bottom of the transmission gear, a second rotating shaft is fixedly connected inside the driven gear, and one end of the second rotating shaft is plugged into one side of the operating table; a transmission roller is fixedly connected to the first rotating shaft, and a cleaning roller is fixedly connected to the outside of the second rotating shaft; a blanking plate is fixedly arranged inside the operating table, a collecting frame is movably connected to the bottom of the operating table, and a pull rod is fixedly connected to the outside of the collecting frame.

[0010] By adopting the above technical solution: the double-headed motor drives the push plate to push the construction waste cut from the surface of the operating table, so that the construction waste can quickly fall onto the conveyor belt. At the same time, when the push plate is reset, the push plate will be tilted to a certain extent to prevent the push plate from concentrating dust between the push plate and the double-headed motor during the reset process, thereby cleaning the surface of the operating table more cleanly.

By setting up a grinding and cleaning mechanism, compared with the prior art, after the plates are segmented, the surfaces of the plates that can be reused are repeatedly grinded, so that the discarded plates can be reused for the second time, thereby improving the utilization rate of the plates in the construction waste. At the same time, the dust after the plates are grinded can be collected. Then, under the limit of the two sliders and the stopper, when the push plate is reset after pushing the construction waste, some residues can be avoided from staying on one side of the push plate, and the residues on the surface of the operating table can be pushed out more completely, so that the surface of the operating table can be kept clean, and the efficiency of subsequent construction waste segmentation can be accelerated; 2. By setting up a crushing and recycling mechanism, compared with the existing technology, the distance between the two positioning rods can be adjusted according to the different types of construction waste, so as to facilitate the crushing of different construction wastes into different sizes, so that the crushed construction waste can be more suitable for different recycling standards. At the same time, it can reduce the dust dissipated into the air during crushing, so that the air quality can be protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The embodiment of the present application discloses a construction waste recycling device, including an operating table 1, a cutting machine body 2 is fixedly connected to the outside of the operating table 1, a fixing plate 3 is fixedly connected to one side of the operating table 1, and a grinding and cleaning mechanism is arranged on the lower surface of the fixing plate 3; the grinding and cleaning mechanism includes a first motor 4, the top of the first motor 4 is fixedly connected to the lower surface of the fixing plate 3, the output end of the first motor 4 is fixedly connected to a first rotating shaft 5, a driving gear 6 is fixedly connected to the first rotating shaft 5, a transmission gear 7 is meshed at the bottom of the driving gear 6, a limiting rod 8 is movably connected inside the transmission gear 7, and the limiting rod 8 is fixedly connected to the side of the operating table 1, and a driven gear 9 is meshed at the bottom of the transmission gear 7, a second rotating shaft 10 is fixedly connected inside the driven gear 9, and one end of the second rotating shaft 10 is plugged into one side of the operating table 1; a transmission roller 11 is fixedly connected to the first rotating shaft 5, and the second rotating shaft 10 is fixedly connected to the second rotating shaft 10. A cleaning roller 12 is fixedly connected to the outside; a blanking plate 13 is fixedly arranged inside the operating table 1, a collecting frame 14 is movably connected to the bottom of the operating table 1, and a pull rod 15 is fixedly connected to the outside of the collecting frame 14. The first motor 4 drives the active gear 6, the transmission gear 7 and the driven gear 9 to engage and transmit. The large-diameter active gear 6 and the small-diameter driven gear 9 are used to maintain the speed difference between the transmission roller 11 and the cleaning roller 12. After the plate enters the interior of the operating table 1, the transmission roller 11 drives the plate to move inside the operating table 1, and the cleaning roller 12 maintains a high speed to grind and clean the lower surface of the plate, and then repeats the grinding once, so that the plate can be reused. At the same time, the cleaned dust and impurities fall into the interior of the collecting frame 14, and the pull rod 15 can be pulled to take out the collecting frame 14 for effective cleaning.

During the resetting process of the push plate 21, the two push-pull rods 20 pull the push plate 21 to move backward. The push plate 21 forms a certain inclination under the action of the positioning rod 22 and the slider 23, so that a gap is formed between the bottom of the push plate 21 and the upper surface of the operating table 1. During the resetting process of the push plate 21, the impurities on the surface of the operating table 1 will not be concentrated at the angle between the push plate 21 and the operating table 1, so that the push plate 21 can completely clean the surface of the operating table 1.

[0031] Reference Figure 5 As shown, a bracket 25 is provided on the other side of the operating platform 1, and a conveyor belt 26 is provided inside the bracket 25. The conveyor belt 26 smoothly conveys the cut construction waste.

[0032] Reference Figure 6 and Figure 7 As shown, a crushing and recycling mechanism is provided on one side of the bracket 25, and the crushing and recycling mechanism includes a processing box 27, which is provided on one side of the bracket 25. A first horizontal plate 28 is fixedly connected to the front side of the processing box 27, and two first positioning frames 29 are slidably connected inside the first horizontal plate 28. Two latches 30 are inserted at the bottom of the first positioning frame 29, and a second motor 31 is fixedly connected inside the first positioning frame 29. A third rotating shaft 32 is fixedly connected to the output end of the second motor 31, and a crushing roller 33 is fixedly connected to the outer side of the third rotating shaft 32. A second positioning frame 34 is sleeved on one end of the third rotating shaft 32, and a second horizontal plate 35 is slidably connected to the bottom of the second positioning frame 34. By pulling the two latches 30, the two first positioning frames 29 can slide inside the first horizontal plate 28, so that the distance between the two crushing rollers 33 can be adjusted to a certain extent, thereby crushing construction waste of different sizes.

[0033] Reference Figure 7 As shown, a dust hood 36 is fixedly connected to the upper surface of the processing box 27, a fan 37 is installed inside the dust hood 36, a collecting pipe 38 is connected to one side of the dust hood 36, one end of the collecting pipe 38 is connected to the processing box 27, and the fan 37 collects the dust that escapes into the air during the crushing process of construction waste, so that the dust can enter the interior of the processing box 27 through the collecting pipe 38.

[0034] Working principle of the present invention: when cleaning construction waste, first place the plate on the top of the operating table 1, cut the plate to a certain size through the cutting machine body 2, and then put the plate with a higher degree of appearance integrity into the opening at the bottom of the operating table 1. At this time, the first motor 4 drives the first rotating shaft 5 to rotate, and the first rotating shaft 5 drives the driving gear 6 to mesh with the transmission gear 7, and then the transmission gear 7 meshes with the driven gear 9 at the bottom. Due to the different diameters of the driving gear 6 and the driven gear 9, the rotation of the driving roller 11 and the cleaning roller 12 is different, and the slower rotating one The driving roller 11 transports the plate smoothly, and at the same time, the driven gear 9 drives the cleaning roller 12 to quickly rotate the lower surface of the plate through the second rotating shaft 10, so that the lower surface of the plate is cleaned by the cleaning roller 12, and then the cleaned plate is output from the rear side of the operating table 1, and then the plate is turned over and inserted into the inside of the operating table 1 to clean the other side of the plate, and then the dust cleaned by the cleaning roller 12 falls into the inside of the collecting frame 14 through the unloading plate 13, and the collecting frame 14 can be pulled out from the bottom of the operating table 1 by the pull rod 15, so as to facilitate the cleaning of the dust inside the collecting frame 14; After the unusable plates and other construction waste are cut to a certain extent by the cutting machine body 2, the double-headed motor 16 drives the transmission disc 18 through the two positioning blocks 17, so that the two transmission discs 18 can keep rotating at the same speed, and then the two transmission discs 18 drive the push-pull rods 20 to push forward and backward through the connecting rod 19, and the two push-pull rods 20 push the push plate 21 to move on the top of the operating table 1, and the push plate 21 pushes the construction waste cut on the top of the operating table 1 to the top of the conveyor belt 26. At the same time, in the process of the two transmission discs 18 pulling the push plate 21 to move backward through the push-pull rods 20, the push plate 21 can keep a certain inclination during the process of resetting the push plate 21 on the top of the operating table 1 through the positioning rod 22 and the two sliders 23, so that the push plate 21 will not concentrate the residual garbage on the surface of the operating table 1 on one side during the resetting process. When the push plate 21 is pushed out again, the push plate 21 can be kept vertical by the limiting position of the blocking rod 24, so that the residual garbage on the surface of the operating table 1 can be pushed out of the top of the operating table 1. Afterwards, the conveyor belt 26 transports all the construction waste to the top of the processing box 27. According to the type of construction waste that needs to be crushed, the pins 30 on the outside of the two first positioning frames 29 are pulled to make the two first positioning frames 29 and the third rotating shaft 32 slide inside the first cross plate 28 and the second cross plate 35 respectively, so that the spacing between the two crushing rollers 33 can be adjusted, and then the corresponding pins 30 are reinserted into the first cross plate 28. Then, when the construction waste enters the interior of the processing box 27, the two second motors 31 drive the third rotating shaft 32 and the crushing rollers 33 to rotate, and the two crushing rollers 33 crush the construction waste. Then, the crushed construction waste falls into the collection box at the bottom of the processing box 27 for easy recycling. Finally, the fan 37 collects the dust generated by the two crushing rollers 33 crushing the construction waste into the interior of the processing box 27 through the dust hood 36 and the collection pipe 38 to prevent the dust from being dissipated in the air over a large area.
