For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Please refer to Figures 1-4The utility model provides a technical scheme: a wave shape stainless steel sieve plate, including a plurality of mutually connected sieve plate 1, every sieve plate 1 is provided with gradually increasing sieve hole 2 along the downward inclined direction, and the opposite fixed plate 3 is fixedly connected on the side wall of the sieve plate 1 between every two sieve plate 1 and the upper sieve plate 1, the adjusting plate 4 is rotatably arranged between two adjacent fixed plate 3, the connecting plate 5 is fixedly connected on the side wall of the sieve plate 1 between every two sieve plate 1 and the lower sieve plate 1, and the adjusting plate 4 and the connecting plate 5 are rotatably installed between two adjacent fixed plate 3 through adjusting assembly 6.

[0029] As shown in the figure, Figure 1 The whole sieve plate main part is composed of sieve plate one B, sieve plate two C and sieve plate three D, sieve plate one B is located at the uppermost level of the whole sieve plate main part, sieve plate three D is located at the lowermost level of the whole sieve plate main part, and the sieve hole 2 on sieve plate one B, sieve plate two C and sieve plate three D gradually increases to meet the needs of step-by-step screening; the material to be screened rolls down from sieve plate one B, is first screened through the sieve hole 2 on sieve plate one B, then is screened again through the sieve hole 2 on sieve plate two C, and finally is screened through the sieve hole 2 on sieve plate three D;

[0030] In the process of screening the material on the sieve plate 1, the adjusting assembly 6 can be used to adjust the inclination angle of the adjusting plate 4, so that the material bounces off the sieve plate 1, the larger the volume of the material, the farther the bouncing distance, so that the material with a larger volume can directly pass through sieve plate two C and enter the screening range of sieve plate three D, further screening the material, reducing the time of screening different volume materials together on the same sieve plate 1, and improving the screening efficiency;

[0031] In addition, the inclination angle of the sieve plate 1 can be adjusted by the adjusting assembly 6; when the material to be screened is too much, the inclination angle of the sieve plate 1 is small, so that the material slowly rolls down from the sieve plate 1, to ensure the thoroughness of screening; when the material to be screened is too much, the inclination angle of the sieve plate 1 is large, so that the material quickly rolls down from the sieve plate 1, improving the screening efficiency of the material.

[0032] Further, one end of the adjusting plate 4 and the connecting plate 5 is rotatably installed on one of the fixed plates 3 through the connecting rod, and the other end of the adjusting plate 4 and the connecting plate 5 is rotatably installed on the other fixed plate 3 through the adjusting assembly 6.

[0033] Further, the adjusting assembly 6 installed on the adjusting plate 4 and the connecting plate 5 is not located on the same side.

[0034] Specifically, the adjusting assembly 6 connected to the adjusting plate 4 and the connecting plate 5 is not arranged on the same side, which facilitates differentiation while ensuring the balance of the whole sieve plate device.

[0035] Furthermore, the adjustment assembly 6 includes a rotating block 61, and a fixing rod 62 is fixedly connected between the rotating block 61, the adjustment plate 4, and the connecting plate 5. The fixing rod 62 passes through the fixing plate 3.

[0036] Furthermore, the rotating block 61 is provided with a number of mounting slots 63, which are evenly distributed around the fixed rod 62. Each mounting slot 63 is connected to a movable block 65 by a telescopic spring 64, and each movable block 65 is equipped with a ball bearing 66. Limiting slots 67 are provided on the side walls of the sieve plate 1 and the fixed plate 3 at the locations corresponding to the ball bearing 66.

[0037] Specifically, the two ends of the telescopic spring 64 are fixedly connected to the inner wall of the mounting groove 63 and the side wall of the movable block 65, respectively; the movable block 65 can drive the ball bearing 66 to extend and retract within the mounting groove 63 with the help of the telescopic spring 64.

[0038] like Figure 4 As shown, the rotating block 61 has eight mounting slots 63, with a 45° interval between each pair of adjacent mounting slots 63. When the rotating block 61 drives the adjusting plate 4 or the connecting plate 5 to rotate via the fixed rod 62, the rotating block 61 will synchronously drive the movable block 65 and the ball 66 to rotate. The ball 66 will retract from the current limiting slot 67 into the corresponding mounting slot 63. When it moves to the adjacent limiting slot 67, the movable block 65 uses the elastic force of the telescopic spring 64 to drive the ball 66 to embed into the limiting slot 67, thereby limiting the rotation of the rotating block 61 and realizing the rotation of the rotating block 61.

[0039] The working principle and usage process of this utility model: After the utility model is installed, the material to be screened rolls down from the screen plate 1B, first through the screen hole 2 on the screen plate 1B for initial screening, then through the screen hole 2 on the screen plate 2C for secondary screening, and finally through the screen hole 2 on the screen plate 3D to complete the screening.

[0040] During the screening process of materials on screen plate 1, the tilt angle of adjustment plate 4 can be adjusted by adjustment component 6, so that the materials bounce off screen plate 1. The larger the volume of the materials, the farther they bounce, so that the larger materials can directly pass through screen plate 2C and enter the screening range of screen plate 3D for further screening, reducing the time for materials of different volumes to be screened together on the same screen plate 1 and improving screening efficiency.

[0041] In addition, the tilt angle of the screen plate 1 can be adjusted by adjusting component 6; when there is too much material to be screened, the tilt angle of the screen plate 1 is smaller, so that the material rolls down slowly from the screen plate 1 to ensure thorough screening; when there is too much material to be screened, the tilt angle of the screen plate 1 is larger, so that the material rolls down quickly from the screen plate 1 to improve the screening efficiency of the material.

[0042] When the adjusting plate 4 needs to be rotated, the rotating block 61 is rotated to drive the adjusting plate 4 to rotate, and when the inclination angle of the screen plate 1 needs to be adjusted, the screen plate 1 is directly rotated to synchronously drive the corresponding connecting plate 5 and the rotating block 61 to rotate.

[0043] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
