DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the technical solution of the present invention in detail with reference to the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0025] Please refer to Figure 1-6 As shown, an anti-blocking mechanism for an aggregate screening machine includes an aggregate screening device 1. A mounting plate 2 is installed at the top of the aggregate screening device 1. The inner wall of the mounting plate 2 is provided with a rotating plate 3. A feeding cylinder 4 is installed at the top of the rotating plate 3. A rotating motor 7 is installed at the top of the aggregate screening device 1. The output shaft of the rotating motor 7 is movably connected to a transmission shaft 6 through a coupling. A conveyor belt 5 is installed on the outer wall of the transmission shaft 6, and the other end of the conveyor belt 5 is sleeved on the outer wall of the feeding cylinder 4.

[0026] A discharge port 11 is opened at the bottom of the aggregate screening device 1. A telescopic sleeve rod 16 is installed at the bottom of the aggregate screening device 1. A vibration frame 18 is installed at the bottom end of the telescopic sleeve rod 16. By installing a feeding cylinder 4 with a rotating effect at the top of the aggregate screening device 1 and a vibration frame 18 with a vibrating effect at the bottom of the discharge port 11, it has the function of inlet and outlet screening during the feeding and discharging processes of the aggregate screening device 1, realizing the anti-blocking mechanism for the aggregate screening machine. The aggregate raw materials are distributed crosswise between the rotating feeding cylinder 4 and the first baffle 8 and the second baffle 9, which can feed the aggregate raw materials at intervals. At the same time, when the aggregate raw materials are poured into the vibration frame 18 through the discharge port 11, the filtered aggregate raw materials are secondarily screened by the filter plate 20, improving the working efficiency of the aggregate screening device 1. It solves the problem that the general aggregate screening device has a simple structure and only a very simple screening structure, and it is easy to cause blockage when a large amount of aggregate raw materials are uniformly poured into the screening machine and poured out from the screening machine, resulting in a reduction in the feeding speed and discharging speed of the aggregate screening machine, improving the efficiency of the anti-blocking mechanism for the aggregate screening machine. A connection groove 19 is opened at the bottom of the vibration frame 18, and a filter plate 20 is installed inside the connection groove 19. A vibration motor 17 is installed on the outer wall of the aggregate screening device 1. The output shaft of the vibration motor 17 is movably connected to the vibration frame 18 through a coupling. A support 10 is installed on the outer wall of the aggregate screening device 1.

[0027] During operation, first start the rotating motor 7. The rotating motor 7 drives the transmission shaft 6 to drive the conveyor belt 5 to rotate, driving the feeding cylinder 4 to rotate, causing the rotating plate 3 at the bottom to rotate inside the mounting plate 2. Pour the aggregate raw materials to be screened into the inside through the feeding cylinder 4. The rotating feeding cylinder 4 causes the first baffle 8 and the second baffle 9 at the bottom to always rotate. The aggregate raw materials are poured downward into the inside of the aggregate screening device 1 through the gap between the first baffle 8 and the second baffle 9 for screening. After screening the aggregate raw materials in the aggregate screening device 1, the rotating shaft 12 rotates the baffle plate 13 to expose the discharge port 11, allowing the aggregate raw materials to fall downward through the discharge port 11 to the vibration frame 18. At the same time, start the vibration motors 17 on both sides. The vibration motors 17 drive the vibration frame 18 to vibrate at the bottom of the aggregate screening device 1, and the filter plate 20 at the bottom is used to simply screen the aggregate. Finally, the aggregate raw materials staying on the surface of the filter plate 20 slide out to one side through the connecting groove 19, and the aggregate raw materials on the surface of the filter plate 20 are processed, thus completing the work.

[0028] In this embodiment, a first baffle 8 is installed at the bottom of the aggregate screening device 1, and a second baffle 9 is installed at the bottom of the rotating plate 3. Both the first baffle 8 and the second baffle 9 are semi-circular baffles, and the first baffle 8 and the second baffle 9 are cross-arranged at the bottom of the feeding cylinder 4. By cross-arranging the first baffle 8 and the second baffle 9 and allowing the feeding cylinder 4 to rotate, intermittent feeding of the aggregate raw materials inside the feeding cylinder 4 can be achieved, avoiding the problem of material feeding blockage of the aggregate raw materials.

[0029] In this embodiment, a rotating groove that matches the shape and size of the bottom of the feeding cylinder 4 is formed on the inner wall of the rotating plate 3, and the rotating plate 3 is rotationally connected to the feeding cylinder 4 through the rotating groove. The feeding cylinder 4 is in the shape of a downward funnel. When the feeding cylinder 4 rotates, the feeding speed of the raw materials inside the feeding cylinder 4 can be controlled.

[0030] In this embodiment, a rotating shaft 12 is installed at the bottom of the aggregate screening device 1, a baffle plate 13 is installed on the outer wall of the rotating shaft 12, and a hook 14 is installed on the outer wall of the baffle plate 13. A hanging rod 15 with the same shape and size as the hook 14 is installed at the bottom of the aggregate screening device 1, and the hook 14 is snap-connected to the hanging rod 15 through the rotating shaft 12. By providing a baffle plate 13 at the bottom of the aggregate screening device 1 installed at the bottom of the discharge port 11, the position between the baffle plate 13 and the discharge port 11 can be rotated by the rotating rotating shaft 12. And by using the hook 14 and the hanging rod 15, the baffle plate 13 can be rotated to completely cover the surface of the discharge port 11 at the bottom of the discharge port 11, realizing the function that the anti-blocking mechanism for the aggregate screening machine can control the discharge speed of the aggregate raw materials, solving the problems of simple structure and single functionality of general aggregate screening machines, and improving the adaptability of the anti-blocking mechanism for the aggregate screening machine.

[0031] In this embodiment, the telescopic sleeve rod 16 is a two-section telescopic sleeve rod, and there are two groups of telescopic sleeve rods 16. The vibration frame 18 is telescopically connected to the bottom of the aggregate screening device 1 through the two groups of telescopic sleeve rods 16. The vibration frame 18 is located at the bottom of the discharge port 11, and the center lines of the discharge port 11 and the vibration frame 18 coincide. By installing the vibration frame 18 at the bottom of the aggregate screening device 1 using the two groups of telescopic sleeve rods 16, the vibration frame 18 can play a role of vibration support during the up-and-down vibration process, and play a stabilizing role when the vibration frame 18 vibrates.

[0032] In this embodiment, a connecting block that is identical in shape and size to the connecting groove 19 is installed on the top of the filter plate 20. The filter plate 20 is slidably connected to the bottom of the vibration frame 18 through the connecting block and the connecting groove 19. The connecting block and the connecting groove 19 provided can install the filter plate 20 at the bottom of the vibration frame 18 and play a role in quick installation and disassembly.

[0033] In this embodiment, filter holes are formed on the surface of the filter plate 20, and the filter holes penetrate through the filter plate 20. A plurality of filter holes are provided and are evenly distributed on the surface of the filter plate 20. Through the provided filter holes, the screened aggregate raw materials can be secondarily screened, improving the working efficiency of screening the aggregate raw materials.

[0034] In summary, for the anti-blocking mechanism of the aggregate screening machine, the aggregate raw materials are cross-distributed between the rotating feeding cylinder 4 and the first baffle 8 and the second baffle 9, so that the aggregate raw materials can be fed at intervals. At the same time, when the aggregate raw materials are poured into the vibration frame 18 through the discharge port 11, the filter plate 20 is used to secondarily screen the screened aggregate raw materials, improving the working efficiency of the aggregate screening device 1. It solves the problem that the general aggregate screening device has a simple structure and only a very simple screening structure, and it is easy to cause blockage when a large amount of aggregate raw materials are uniformly poured into the screening machine and poured out of the screening machine, resulting in a reduction in the feeding speed and discharging speed of the aggregate screening machine, and improves the efficiency of the anti-blocking mechanism for the aggregate screening machine.
