Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material screening, in particular to a rapid screening device for commercial concrete raw materials. Background Technique

[0002] The rapid screening device for commercial concrete raw materials is mainly used to screen concrete raw materials and select qualified raw materials. Concrete is mainly composed of minerals such as stones and sand, and water.

[0003] For example, in the rapid screening device for commercial concrete raw materials described in the patent with the patent publication number CN212732981U, in the solution described therein, the feeding port is arranged above the middle of the horizontal sieve plate. When the concrete raw materials to be screened are poured into the housing II from the feeding port, the concrete raw materials will first fall on the horizontal sieve plate. Those with particle sizes smaller than the aperture of the sieve holes will quickly fall into the cavity of the housing I under the action of the vibration motor, and those with particle sizes larger than the aperture of the sieve holes will stay on the sieve plate all the time and finally fall onto the inclined sieve plate under the action of the vibration motor.

[0004] There are limitations in the above case. Since there is more than one type of concrete raw material, the number of screening times is naturally the same. The diameters of each type of concrete raw material are different, so the sieve mesh needs to be selected according to different diameters. This device can only screen out one type of qualified raw material, greatly reducing the efficiency.

[0005] Based on this, a rapid screening device for commercial concrete raw materials is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6, in the embodiment of the present utility model, a rapid screening device for commercial concrete raw materials includes an isolation box 1. A feed inlet 2 is fixedly connected to the top of the isolation box 1, and a discharge outlet 20 is provided at the bottom of the isolation box 1. Below the feed inlet 2, a screening assembly for screening concrete raw materials is provided.

[0031] In one embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, the screening assembly includes a rotating motor 3, and fixing blocks 4 for support are provided on the left and right sides of the rotating motor 3. The bottom of the fixing block 4 is fixedly connected to the outside of the isolation box 1. The top of the output end of the rotating motor 3 is fixedly connected with an eccentric turntable 5. The eccentric turntable 5 is embedded in a sliding frame at one end of a connecting rod 6, and the convex column of the eccentric turntable 5 is slidably connected with the sliding frame. A sieve plate 7 is fixedly connected to the side of the connecting rod 6 away from the eccentric turntable 5. Large sieve holes 17 and small sieve holes 18 are respectively provided on the left and right sides of the sieve plate 7, and limiting holes are provided at the left and right positions inside the sieve plate 7. Support rods 8 are movably connected to the inner walls on the left and right sides of the sieve plate 7, and the two sides of the support rods 8 away from the sieve plate 7 are fixedly connected to the inside of the isolation box 1. A first limiting groove 9 is provided on one side of the sieve plate 7, and a second limiting groove 10 is provided on one side of the isolation box 1. A discharge plate 11 is fixedly connected to the other side of the sieve plate 7, and a side outlet 12 is provided on the side of the isolation box 1 where the discharge plate 11 is located. An isolation assembly for isolating the sieve plate 7 is provided above the sieve plate 7. By operating the rotating motor 3 to drive the eccentric turntable 5 to rotate, the eccentric turntable 5 moves in the sliding frame of the connecting rod 6. In this way, when the eccentric turntable 5 rotates to the left and right positions, it will enter the chute, so it will not drive the connecting rod 6 to move. Only when moving forward and backward will it drive the connecting rod 6 to move together. Therefore, the movement of the connecting rod 6 will drive the sieve plate 7 to slide, playing a role in screening. Sieve holes of different sizes can adapt to different types of concrete raw materials.

[0032] In one embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the isolation assembly includes an isolation plate 13. The bottom of the isolation plate 13 is movably abutted against the upper end surface of the sieve plate 7. A connecting plate 14 is fixedly connected to one side of the isolation plate 13, and the outer surface of the connecting plate 14 is slidably connected to the inner walls of the first limiting groove 9 and the second limiting groove 10. A limiting assembly for limiting the isolation plate 13 is provided inside the sieve plate 7. The connecting plate 14 moves in the first limiting groove 9 and the second limiting groove 10 to drive the isolation plate 13 to move on the sieve plate 7.

[0033] In one embodiment, as Figure 5As shown, the limiting component includes a spring 15, which is respectively embedded in the limiting holes on the left and right inside the sieve plate 7. The bottom of the spring 15 is fixedly connected to the inside of the sieve plate 7, and the top of the spring 15 is fixedly connected with a limiting column 16. The moving partition plate 13 is limited by the limiting column 16, so that it cannot move randomly without applying external force. By applying external force to the partition plate 13, it can cross over the limiting column 16. When the limiting column 16 is stressed, the spring 15 at its bottom is compressed, thereby reducing the height so that the partition plate 13 can pass smoothly. After the partition plate 13 leaves, the spring 15 will drive the limiting column 16 back to its original position to play a limiting role without applying external force.

[0034] Embodiment 2

[0035] In one embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, a handle 19 is fixedly connected to the side of the connecting plate 14 away from the partition plate 13. By pulling the handle 20, the connecting plate 14 is driven to move, so as to move the partition plate 13 more conveniently.

[0036] In one embodiment, as Figure 5 shown, the upper end of the limiting column 16 is arc-shaped, so that when an external force is applied to the partition plate 13, it is easy to move on the limiting column 16.

[0037] In one embodiment, as Figure 5 shown, the thickness of the partition plate 13 does not affect the screening of concrete raw materials, so that the concrete raw materials are not interfered during screening and can be screened smoothly.

[0038] In one embodiment, as Figure 2 shown, the top opening of the feed inlet 2 is larger than the bottom opening, which is convenient for the entry of concrete raw materials.

[0039] The working principle of the present utility model is as follows: The above-mentioned embodiment discloses a rapid screening device for commercial concrete raw materials. Concrete raw materials are added through the feed inlet 2 and enter the interior of the isolation box 1 and fall on the sieve plate 7. The operation of the rotating motor 3 drives the operation of the eccentric turntable 5. Since the eccentric turntable 5 is slidably connected within the sliding frame of the connecting rod 6, when the eccentric turntable 5 moves to the left and right positions, it moves within the sliding frame. Only when the eccentric turntable 5 moves to the front and rear positions, the connecting rod 6 will be driven by the eccentric turntable 5 to operate. The operation of the connecting rod 6 will perform a pulling and pushing movement on the sieve plate 7, enabling it to perform the screening function. The sieve plate 7 is provided with large sieve holes 17 and small sieve holes 18, enabling it to adapt to raw materials of different sizes. After determining which side of the sieve holes to use, the isolation plate 13 can be moved to isolate the sieve holes on the other side. Since the interior of the sieve plate 7 is provided with limit clamping columns 16, the isolation plate 13 will be limited without applying external force, thus not interfering with the normal operation of the screening assembly. The raw materials that fail to pass the screening will be screened out from the side outlet 12 by the screening assembly, and the qualified raw materials will fall into the discharge port 20, enabling the next process to be carried out.

[0040] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
