Description

Technical Field

[0001] This application relates to the technical field of concrete recycling, and specifically provides a concrete recycling machine. Background Art

[0002] Concrete is a commonly used material in construction projects. It is a material composed mainly of cement as the main binder, water, aggregates such as sand and gravel, and when necessary, chemical admixtures and mineral admixtures are incorporated, mixed in appropriate proportions, and formed into a material through uniform mixing, dense compaction, and curing and hardening.

[0003] At the production base of concrete, mixers are mostly used to mix raw materials to form viscous concrete raw materials. After the demolition of concrete buildings, a large amount of concrete solid waste is generated. Currently, concrete recycling machines are mostly used to make the concrete waste into aggregates and further into recycled concrete for reuse.

[0004] For example, the patent with the publication number CN216266836U specifically discloses a stone-reducing concrete recycling machine, including the settings of support blocks, fixed brackets, rotating brackets, support frames, cylinders, and feeding ports. Thus, the concrete waste is conveyed through the rotating bracket to cooperate with the feeding port and fall into the cylinder interior, and then the cylinder crushes the concrete waste.

[0005] During the use of the above-mentioned patent concrete recycling machine, since the feeding port is in an open state, when the concrete waste enters the cylinder for crushing through the feeding port, it is easy for the concrete debris to fly, and at the same time, when processing the concrete waste, it is easy for the dust to fly everywhere during the crushing of the concrete, thus causing a certain impact on the environment. Therefore, it is necessary to design a concrete recycling machine to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

[0008] The technical solution adopted by the present application to solve its technical problems is as follows: A concrete recycling machine mainly includes: a support frame; a crushing structure, which has a cylinder body installed on the support frame and a crushing rod passing through the cylinder body. The crushing rod has crushing blades, and a feed port is provided on the cylinder body; a motor, which is installed on the support frame; an opening and closing structure, which has a funnel installed in the feed port and a cover plate hinged on the funnel. Two groups of cylinders are installed on the cylinder body; a connecting block, which is installed on the cover plate, and the connecting block has a screw rod; a sleeve rod, which is installed at the output end of the cylinder.

[0009] Further, a nut is connected to one end of the screw rod away from the connecting block.

[0010] Further, bearing seats are installed at both ends of the cylinder body on the support frame, and bearings adapted to the bearing seats are installed on the crushing rod.

[0011] Further, a support block is installed on one side of the support frame, a support seat is installed on the support block, and a conveyor belt is installed on the support seat. The conveyor belt is inclined.

[0027] As Figure 1 - Figure 2 shown, this application provides a concrete recycling machine, including a support frame 4, and a crushing structure 5 is installed on the support frame 4. The crushing structure 5 includes a cylinder body 501 installed on the support frame 4. At the same time, a crushing rod 504 penetrates through the cylinder body 501, and the crushing rod 504 is provided with crushing blades (not shown in the figure);

[0028] Moreover, a motor 503 is fixedly installed on the support frame 4. Bearing seats 502 are fixedly installed at both ends of the cylinder body 501 on the support frame 4 at the same time. The bearing seats 502 are used to limit both ends of the crushing rod 504. Meanwhile, bearings (not shown in the figure) adapted to the bearing seats 502 are installed on the crushing rod 504. The output end of the motor 503 is connected to one end of the crushing rod 504 to be adapted to rotate the crushing rod 504, thereby crushing the concrete waste;

[0029] Meanwhile, a support block 1 is installed on one side of the support frame 4. A support seat 2 is installed on the support block 1. Meanwhile, a conveyor belt 3 is installed on the support seat 2. The conveyor belt 3 is inclined and is used to convey the concrete waste;

[0030] As Figure 2 - Figure 3 shown, a feed inlet 505 is formed in the cylinder body 501. Meanwhile, an opening and closing structure 6 is installed in the feed inlet 505. The opening and closing structure 6 includes a funnel 601 installed in the feed inlet 505. A cover plate 602 is hinged on the funnel 601. And air cylinders 603 are installed at both sides of the funnel 601 on the cylinder body 501 at the same time;

[0031] Moreover, a connecting block 604 is fixedly installed on the cover plate 602. A screw rod (not marked in the figure) is provided on the connecting block 604. And a sleeve rod 605 is provided at the output end of the air cylinder 603. The sleeve rod 605 is movably sleeved on the screw rod. The cover plate 602 is adapted to rotate on the funnel 601 along with the output end of the air cylinder 603 to open and close the funnel 601. Meanwhile, a nut (not marked in the figure) is connected to one end of the screw rod far from the connecting block 604. The nut is adapted to prevent the sleeve rod 605 from slipping off the screw rod;

[0032] As Figure 2 and Figure 4 shown, a spraying structure 7 is installed on the support frame 4. The spraying structure 7 includes two groups of support rods 701 installed on the support frame 4. The support rods 701 have an installation groove 702. And an adjusting rod 703 is installed in the installation groove 702. The adjusting rod 703 is adapted to move along the linear direction of the installation groove 702. Meanwhile, a fastener (not marked in the figure) is connected to the support rod 701. The fastener is adapted to penetrate and be connected to the support rod 701 and the adjusting rod 703;

[0033] And a water tank 704 is fixedly installed on one group of adjusting rods 703. The water tank 704 has a water pump (not shown in the figure). The water outlet end of the water pump is installed with a water pipe 705. Meanwhile, spray heads 706 are connected to the two groups of adjusting rods 703. One end of the water pipe 705 is connected to the spray heads 706.

[0034] During use, the concrete waste is conveyed by the conveyor belt 3. At the same time, the water source in the water tank 704 is sucked by starting the water pump and sprayed onto the concrete waste through the nozzle 706. The concrete waste then enters the cylinder body 501 through the funnel 601. At this time, when the crushing blades in the cylinder body 501 crush the concrete waste, the generation of dust is reduced to a certain extent. At the same time, when a certain amount of concrete waste is put in, the cover plate 602 is driven to rotate by starting the cylinder 603 to cover the cover plate 602 on the funnel 601, so as to prevent the concrete debris from splashing everywhere during crushing;

[0035] In summary: Through the coordinated use of the funnel 601, the cover plate 602, the cylinder 603, the connecting block 604 and the sleeve rod 605, a better protection effect can be provided to prevent the concrete debris from splashing from the funnel 601 when the concrete waste is crushed. And through the setting of the water tank 704, the water pipe 705 and the nozzle 706, the concrete waste entering the cylinder body 501 is wetted, which helps to prevent the dust of the concrete waste from flying when the crushing blades break it.

[0036] The above is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
