[0022] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] like Figures 1-3 As shown in the first embodiment, a concrete production raw material screening device is disclosed, including a screen 1. Both ends of one side of the screen 1 are hinged to the mounting frame 3 via hinge shafts 2. Both ends of the other side of the screen 1 are fixed with connecting shafts 4. The connecting shafts 4 pass through the arc-shaped clearance grooves 301 on the mounting frame 3 to their outer side and are hinged with connecting rods 5. The end of the connecting rods 5 is hinged to the elastic telescopic component 6, and the end of the elastic telescopic component 6 is hinged to the mounting frame 3.

[0025] The working principle of the above technical solution is as follows: When the concrete raw material to be screened is added to the screen 1, a certain force is applied to the screen 1. This force will cause the screen 1 to rotate counterclockwise around the axis of the hinge shaft 2. At the same time, the connecting shaft 4 moves in the same direction in the arc-shaped clearance groove 301. Under the action of the connecting rod 5, the elastic telescopic component 6 will rotate around the hinge point between it and the mounting frame 3. At the same time, the elastic telescopic component 6 will be compressed. As the elastic telescopic component 6 is continuously compressed, the rebound force generated will continuously increase. At the same time, some of the raw material with a particle size smaller than the mesh size of the screen 1 will fall below the screen 1, reducing the total weight of the raw material on the screen 1. Under the action of the spring 64, the screen 1 can be driven to rotate clockwise around the axis of the hinge shaft 2. In the above process, the raw material on the screen 1 can be shaken, thereby helping to improve the screening capacity of this utility model.

[0026] By adopting this scheme, during the screening process of concrete raw materials, this utility model, through the above-mentioned structural design, can achieve the effect of continuous shaking of the raw materials without consuming electrical energy. This not only improves the screening capacity of the raw materials but also saves a lot of electrical energy, which is conducive to energy conservation.

[0027] Further optimizing the scheme, the elastic telescopic component 6 includes a mounting plate 61 that is hinged to the end of the connecting rod 5. A telescopic rod 62 is connected to the mounting plate 61, and a mounting plate 63 is connected to the end of the telescopic rod 62. The mounting plate 63 is hinged to the mounting frame 3 through a hinge seat. A spring 64 is sleeved on the outer periphery of the telescopic rod 62, and the two ends of the spring 64 abut against the mounting plate 61 and the mounting plate 63 respectively.

[0028] Specifically, the telescopic rod 62 includes a rod body 621 fixedly connected to the mounting plate 61, the bottom of the rod body 621 slidingly passing through the mounting sleeve 622, and the mounting sleeve 622 fixedly connected to the mounting plate 63.

[0029] In a further optimized design, a guide slider 623 is fixedly connected to the bottom of the rod 621, and a guide groove 624 is provided on the inner wall of the mounting sleeve 622. The end of the guide slider 623 extends into the guide groove 624 and slides therein. Through the guide slider 623 and the guide groove 624, the rod 621 can only move linearly along the length of the guide groove 624, while also preventing the rod 621 from detaching from the mounting sleeve 622.

[0030] Example 2

[0031] like Figures 4-5 As shown, based on the above embodiment one, the difference between this embodiment two and embodiment one is that this embodiment two also includes a cloth hopper 7, which is fixed above the screen 1 by a support frame; the bottom wall of the cloth hopper 7 is provided with a cloth elongated hole 701, and the mounting frame 3 is provided with an opening and closing component 8 for adjusting the opening degree of the cloth elongated hole 701.

[0032] With this scheme, the concrete material in the material can fall onto the screen 1 in a more dispersed manner through the elongated material feeding hole 701, which helps to screen the material. The opening degree of the material feeding hole 701 can be adjusted through the opening and closing component 8, thereby adjusting the amount of material falling.

[0033] Further optimization of the scheme: the opening and closing component 8 includes a support 81 fixedly connected to the mounting frame 3, a horizontal drive component 82 is provided on the support 81, an opening and closing plate 83 is connected to the actuating end of the horizontal drive component 82, and the end of the opening and closing plate 83 penetrates into the fabric hopper 7 and extends above the fabric elongated hole 701.

[0034] In the second embodiment, the opening and closing plate 83 is arranged in an L-shaped structure, the horizontal driving component 82 is arranged as a hydraulic cylinder, the fixed end of the horizontal driving component 82 is fixed on the support 81, the moving end of the horizontal driving component 82 is fixedly connected with the side wall of the vertical section of the opening and closing plate 83, one side wall of the material hopper 7 is provided with an opening, the circumferential side wall of the opening is fixedly provided with an elastic pad arranged in a ring shape, the horizontal section of the opening and closing plate 83 is slidably and sealingly penetrated into the material hopper 7 through the elastic pad, and the side wall thereof is in close contact with the three side walls of the material hopper 7 which are not provided with the opening.

[0035] The above-described embodiments are only used to describe the preferred modes of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
