Description

Technical Field

[0001] The invention relates to the technical field of building engineering construction, in particular to a waste crushing and recycling device for building engineering construction. Background Art

[0002] Buildings refer to artificially constructed assets and fall under the category of fixed assets, including two major categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and conduct other social activities. What is different from buildings is structures, which refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges and chimneys. In construction, construction refers to production activities in the implementation stage of engineering construction, which is the construction process of various buildings.

[0003] Existing environmentally friendly recycling equipment for construction waste materials usually directly collects the construction waste materials through a carrier during its use, and then transports it for secondary processing. This recycling device has a limited recycling volume and requires workers to frequently unload materials. It does not have the function of compressing the waste materials. At the same time, a large amount of dust particles are often raised during the recycling process, causing serious environmental pollution.

[0004] For example, Chinese patent CN114850177A discloses an environmentally friendly recycling device for construction waste materials. Construction waste materials can be conveniently recycled through a feed hopper, and then the raw materials can be crushed by a crushing roller and sent to a recycling box. The cooperation of the extrusion plate and the shielding plate can compress the recycled waste materials in the box into blocks, and the heating pipe in the shielding plate can be used to melt the foam waste materials in the construction waste materials, thereby effectively increasing the recycling volume of the recycling box. The recycling method is convenient and does not require manual operation. The device can automatically crush and compress the waste materials, which is convenient for the later transportation and reprocessing of the waste materials.

[0005] The recycling device squeezes and crushes the construction waste materials through the crushing roller, but it cannot squeeze and crush the waste materials with larger volumes smoothly, thus affecting the smooth recycling of the waste materials.

[0006] Therefore, it is necessary to design a construction waste crushing and recycling device that is highly practical and convenient for crushing waste materials of different volumes. Summary of the invention

Therefore, by first passing a bolt through the circular hole and then threading it into the thread groove, the ring 504 can be fixed to the outer side of the rotating rod 503, thereby fixing the crushing knife 505 to the outer end of the rotating rod 503.

[0035] The rotating shaft 506 is rotatably connected to the left and right ends at the lower part of the crushing box 3, the crushing roller 507 is fixedly connected to the outer side of the rotating shaft 506 located inside the crushing box 3, the gear 508 is fixedly connected to the outer side of the front end of the rotating shaft 506, the second motor 509 is fixedly connected to the left end of the rear side of the crushing box 3, and the feeding pipe 510 is fixedly connected to the lower end of the crushing box 3.

[0036] The disassembly unit includes a connection block 601, a first spring 602, an insertion rod 603 and a fixing frame 604. The connection block 601 is fixedly connected to the middle position of the left and right sides of the box cover 501, the first spring 602 is connected to the lower end of the connection block 601, the insertion rod 603 is fixedly connected to the front end of the first spring 602, and the fixing frame 604 is fixedly connected to the middle position of the upper ends of the left and right sides of the crushing box 3. A rectangular groove is provided on the front side of the lower end of the connection block 601, the rear end of the first spring 602 is fixedly connected to the inner rear end of the rectangular groove, and the outer side of the insertion rod 603 is slidably connected to the inner side of the rectangular groove. Therefore, when the first spring 602 bounces, it can drive the insertion rod 603 to slide along the inner side of the rectangular groove, thereby limiting the movement of the insertion rod 603.

[0037] The front end of the fixed frame 604 is provided with a socket, the outer side of the lower end of the connection block 601 is slidably connected to the inner side of the fixed frame 604, and the outer front end of the insertion rod 603 is plugged into the inner side of the socket.

[0038] The extrusion unit includes a hydraulic cylinder 701, a pressing plate 702, a heating pipe 703 and a blanking plate 704.

The clamping frame 803 is fixedly connected to the rear end of the second spring 802. The outer side of the lower end of the clamping frame 803 is slidably connected to the inner side of the rectangular frame 801. Therefore, when the second spring 802 bounces, the lower end of the clamping frame 803 can be driven to slide along the inner side of the rectangular frame 801, thereby limiting the overall movement of the clamping frame 803.

[0040] The clamping block 804 is fixedly connected to the middle position of the front lower end of the compression box 4. The rear end of the blanking plate 704 is hinged to the rear lower end of the compression box 4 through a hinge, the upper side of the blanking plate 704 abuts against the lower side of the compression box 4, and the inner upper end of the clamping frame 803 abuts against the upper end of the clamping block 804. Therefore, by pulling the clamping frame 803 forward so that the clamping frame 803 is no longer located at the upper end of the clamping block 804, the blanking plate 704 can be rotated away from the lower end of the compression box 4, and the residual material after internal compression is discharged and recovered.

[0041] Working principle: When in use, construction waste is put into the crushing box 3 from the feed pipe 9, and the first motor 502 and the second motor 509 are started. The output shaft of the first motor 502 rotates to drive the rotating rod 503 at the lower end to rotate, so that the crushing knife 505 at the outer end rotates to cut and crush the construction waste entering the crushing box 3. At the same time, the output shaft of the second motor 509 rotates to drive the rotating shaft 506 at the left end inside the crushing box 3 to rotate, thereby driving the gear 508 at the front end of the rotating shaft 506 to rotate relatively, driving the two rotating shafts 506 to rotate relatively, and at the same time, the crushing roller 50 7 rotates relatively to further squeeze and crush the shredded construction waste. After the completely crushed waste enters the compression box 4 from the discharge pipe 510, the heating pipe 703 is started to heat the waste so that the foam waste in the waste melts, and then the hydraulic cylinder 701 is started to push the pressing plate 702 downward to squeeze the melted foam waste until the foam waste cools and solidifies into blocks, and then the card frame 803 is pulled forward until the card frame 803 is no longer located at the upper end of the card block 804, and the discharge plate 704 is rotated away from the lower end of the compression box 4, and the waste in the compression box 4 falls down and is collected.
