Description

Technical Field

[0001] The utility model belongs to the technical field of waste recycling, and particularly relates to a feeding mechanism for a building waste recycling device. Background Technique

[0002] Construction waste refers to the general term of muck, waste concrete, waste steel bars and other wastes generated in the production activities of the construction industry such as demolition, construction, decoration and repair. The commonly used devices for recycling municipal construction waste on the market have the disadvantage of being difficult to separate the waste components. During use, various magnetic and non-magnetic construction wastes are mixed together, making it very difficult to recycle and use.

[0003] Chinese Patent with the authorization announcement number CN217221706U discloses a waste recycling device for municipal construction, which includes a recycling box, a motor, a rotating shaft, an inclined plate, a support plate a, a guide plate a, a guide plate b, an electromagnet and a controller; the motor is arranged on the outer wall of the recycling box, the rotating shaft is rotatably arranged on the inner wall of the recycling box, and a crushing roller is arranged on the rotating shaft; two groups of inclined plates are longitudinally and downwardly inclined on the left and right inner walls of the recycling box; the support plate a is slidably arranged on the rear inner wall of the recycling box; the guide plate a is inclined downward to the right on the left inner wall of the recycling box; the guide plate b is inclined downward to the right, and the lowest end of the guide plate b is rotatably connected to the wall of the square hole; the electromagnet is longitudinally arranged on the front inner wall of the recycling box; the controller is arranged on the outer wall of the recycling box. The utility model can automatically complete the separation and recycling of magnetic waste and non-magnetic waste, does not require manual operation by the user, is convenient to use, and has high waste recycling efficiency.

[0004] The above patent only slides and feeds materials through the guide plate. Under some relatively heavy construction wastes, the sliding friction force on the guide plate will increase, resulting in slow feeding or blockage problems, which is not conducive to rapid feeding, and lacks the ability to quickly push the construction waste for screening the size of the construction waste while feeding. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the technical problems to be solved by the utility model are slow feeding and screening of construction waste.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution: a feeding mechanism for a building waste recycling device, including a material dividing block installed in a feeding cylinder, a feeding port is fixed above the inside of the feeding cylinder, and a number of screening holes are equidistantly distributed on the surface of the material dividing block; the screening holes are used for discharging dust and smaller particle building waste.

[0007] A fixed cylinder is provided below the material distributing block. A motor is installed below the fixed cylinder. An output shaft is provided at the output end of the motor. A plurality of outer scraping plates are distributed around the top end of the output shaft. A raised edge is provided on the periphery of the material distributing block, and a notch groove is provided on the inner wall of the blanking cylinder.

[0008] Under the rotation of the outer scraping plates, the construction waste accumulated on the surface of the material distributing block is scattered, which can promote the movement of the construction waste on the surface of the material distributing block and accelerate the discharging process. It can also prevent the construction waste from accumulating on the surface of the screening holes, which is beneficial to the screening and blanking of the screening holes. When the material distributing block is installed in the blanking cylinder, the material distributing block is placed below the blanking cylinder and pushed upward onto the notch groove, that is, the notch groove and the raised edge are mutually attached and welded and fixed, thereby fixing the material distributing block. And the use of the raised edge can block some smaller waste materials from directly discharging from the material distributing block. When the outer scraping plates rotate, the smaller waste materials are pushed into the screening holes.

[0009] Further, the surface of the material distributing block is inclined downward, which is convenient for the construction waste to roll downward.

[0010] Further, the outer scraping plates are parallel and attached to the surface of the material distributing block. Under the slow rotation of the outer scraping plates, the scraping of the construction waste on the surface of the material distributing block can be improved, and the screening effect and screening efficiency can be improved. The height of the outer scraping plates is equal to the height of the raised edge, so that when the outer scraping plates rotate, the waste materials higher than the height of the raised edge can be pushed out and enter the discharge port for discharging.

[0011] Further, the blanking port is inclined inward to improve the blanking effect.

[0012] Further, a protective cylinder is installed on the periphery of the fixed cylinder. When the motor is under the screening holes for blanking, it will not affect the motor, and the working environment of the motor is improved.

[0013] To sum up, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) The construction waste after being crushed falls from the crushing mechanism onto the blanking port and enters the blanking cylinder. Under the rotation of the outer scraping plates, the construction waste accumulated on the surface of the material distributing block is scattered, which can promote the movement of the construction waste on the surface of the material distributing block and accelerate the discharging process. It can also prevent the construction waste from accumulating on the surface of the screening holes, which is beneficial to the screening and blanking of the screening holes. The larger construction waste is pushed by the outer scraping plates and will roll around and be discharged from the discharge port for the first screening.

[0015] (2) The outer scraping plates are parallel and attached to the surface of the material distributing block. When the construction waste accumulates on the material distributing block, under the slow rotation of the outer scraping plates, the scraping of the construction waste on the surface of the material distributing block can be improved, and during the rotation of the outer scraping plates, the construction waste accumulated on the surface of the material distributing block can be disrupted, preventing the construction waste from concentrating and accumulating on the surface of the material distributing block, and improving the screening effect.

Specific implementation manners

[0020] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] Refer to Figures 1 - 3 , a blanking mechanism for a construction waste recycling device, including a material distributing block 13 installed inside a blanking cylinder 10. The material distributing block 13 plays a role in screening construction waste. A blanking port 11 is fixed above the inside of the blanking cylinder 10. Three discharging ports 12 penetrate through the outer wall of the blanking cylinder 10. The arrangement of the multiple discharging ports 12 is used for discharging waste materials in multiple angular directions. The discharging port 12 is used to discharge larger construction waste inside the blanking cylinder 10. A number of screening holes 14 are equidistantly distributed on the surface of the material distributing block 13. The screening holes 14 are used to discharge dust and smaller particulate construction waste.

[0022] Three supporting feet are installed and supported on the outer wall of the blanking cylinder 10 for stable support of the present utility model. The supporting feet are fixed to the outer wall of the blanking cylinder 10 by welding. Under the supporting action of the supporting feet, a certain distance is maintained between the lower part of the blanking cylinder 10 and the ground. This distance can facilitate the placement of a container for receiving waste materials.

[0023] A fixed cylinder 17 is provided below the material distributing block 13. A motor 16 is installed below the fixed cylinder 17. An output shaft 18 of the motor 16 passes through the fixed cylinder 17 and the material distributing block 13. A number of outer scrapers 19 are circumferentially distributed at the top of the output shaft 18. Under the rotation of the outer scraper 19, the construction waste gathered on the surface of the material distributing block 13 is dispersed, which can promote the movement of the construction waste on the surface of the material distributing block 13 to accelerate the discharging process, and can also prevent the surface of the screening holes 14 from being piled up with construction waste, which is beneficial to the screening and blanking of the screening holes 14.

[0024] Refer to Figure 2, the surface of the material distribution block 13 slopes downward, facilitating the downward rolling of construction waste. The lowest end of the downward slope is flush with the bottom surface of the discharge port 12. The construction waste falling from the feeding port 11 is blocked by the material distribution block 13 and can directly slide out at the discharge port 12.

[0025] A raised edge 20 is provided on the periphery of the material distribution block 13, and a notch groove 22 is provided on the inner wall of the feeding cylinder 10. When the material distribution block 13 is installed in the feeding cylinder 10, the material distribution block 13 is placed below the feeding cylinder 10 and pushed upward onto the notch groove 22, that is, the notch groove 22 and the raised edge 20 are mutually attached and welded and fixed, thereby fixing the material distribution block 13. And the use of the raised edge 20 can block some smaller waste materials from directly discharging from the material distribution block 13. When the outer scraper 19 rotates, the smaller waste materials are pushed into the screening holes 14. The height of the outer scraper 19 is equal to the height of the raised edge 20. In this way, when the outer scraper 19 rotates, the waste materials higher than the height of the raised edge 20 can be pushed out and thus enter the discharge port 12 for discharging.

[0026] Reference Figure 3 , a protective cylinder 15 is installed on the periphery of the fixed cylinder 17. The motor 16 is inside the protective cylinder 15. When the materials fall through the screening holes 14, the falling dust and construction waste will not affect the motor 16, improving the working environment of the motor 16. A space is jointly formed outside the protective cylinder 15 and inside the feeding cylinder 10. This space is used for the feeding of the screening holes 14. During the feeding process, only a container for receiving needs to be placed on the protective cylinder 15 to collect the construction waste discharged from the screening holes 14.

[0027] Reference Figure 2 , the outer scraper 19 is parallel and attached to the surface of the material distribution block 13. When the construction waste accumulates on the material distribution block 13, the slow rotation of the outer scraper 19 can improve the scraping of the construction waste on the surface of the material distribution block 13. And during the rotation of the outer scraper 19, the construction waste accumulated on the surface of the material distribution block 13 can be disrupted, preventing the construction waste from concentrating and accumulating on the surface of the material distribution block 13 and improving the screening effect.

[0028] The outer scraper 19 is made of metal that is resistant to impact and not prone to deformation, with high hardness. When the construction waste falls from above, it will not produce large deformation due to the impact of the waste, thus reducing the service life of the outer scraper 19. And a buffer cotton layer material can also be covered on the outer scraper 19. In this way, the use effect of the outer scraper 19 is improved during use, preventing the outer scraper 19 from being damaged. And the wrapped cotton layer can also better contact the surface of the material distribution block 13, improving the scraping effect.

[0029] Reference Figure 1, the blanking port 11 inclines inward, and the waste materials that directly fall onto the blanking port 11 will quickly slide down on the inclined surface of the waste building materials, further improving the scraping effect of the waste building materials on the surface of the material distribution block 13.

[0030] In this embodiment, when the motor 16 is started, the crushed construction waste falls from the crushing mechanism onto the blanking port 11 and enters the blanking cylinder 10. Under the rotation of the outer scraper 19, the construction waste gathered on the surface of the material distribution block 13 is scattered, which can promote the movement of the construction waste on the surface of the material distribution block 13 and accelerate the discharging process. It can also prevent the construction waste from accumulating on the surface of the screening holes 14, which is beneficial to the screening and blanking of the screening holes 14. The larger construction waste is pushed by the outer scraper 19 and will roll around and be discharged from the discharge port 12 for the first screening. A storage container is placed at the discharge port 12 to receive the waste. Then, some dust and smaller particle construction waste enter the screening holes 14 and are discharged from below the blanking cylinder 10 for the second screening work.
