It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a waste soil and rock screening device, such as Figure 1-4 As shown, the waste soil and rock screening device includes: a base frame 1; a screening frame 2 mounted on the base frame 1, on which multiple screening screen plates 3 are fixedly installed; a vibration mechanism is provided on the base frame 1 and the screening frame 2, which is used to drive the screening screen plates 3 to vibrate and screen the waste soil and rock; a crushing cylinder 4 rotatably mounted on the base frame 1, on which multiple spikes 5 are fixedly installed; and a rotating mechanism assembled on the base frame 1 and the crushing cylinder 4, which is used to drive the spikes 5 to rotate and crush the soil clods in the waste soil and rock.

[0022] In this embodiment, when performing soil and rock screening on waste slag, the rotating mechanism and the vibration mechanism are activated, and the waste slag and rock are put into the crushing cylinder 4. The rotating mechanism drives the crushing cylinder 4 and the spikes 5 to rotate continuously. The waste slag and rock are constantly turned over and collided with the spikes 5 in the crushing cylinder 4. The soil clods in the waste slag and rock have low hardness and are crushed. Then, they enter the screening frame 2 along with the stones. The crushed soil clods are screened out through the uppermost screening screen plate 3 on the screening frame 2. The separated soil and stones are further screened by size through multiple subsequent screening screen plates 3 with different mesh sizes. Through the entire device, the soil and rock in the waste slag and rock can be screened, and large soil clods can be crushed to avoid large soil clods remaining in the stones, thereby improving the effect of soil and rock screening.

[0024] In this embodiment, when using the vibration mechanism, the vibration motor 7 is started, which, with the cooperation of the spring 6, drives the screening frame 2 and multiple screening screen plates 3 to vibrate, and screens the waste slag and soil. A damper is provided between the base frame 1 and the spring 6 to improve the stability of the spring 6 when it deforms.

[0025] In a further preferred embodiment of the present invention, the rotating mechanism includes: a second servo motor 8 fixedly mounted on the base frame 1; a mounting shaft 9 rotatably mounted on the base frame 1, wherein the output shaft of the second servo motor 8 is connected to one end of the mounting shaft 9 via a coupling; and two spur gears 10 respectively fixedly sleeved on the mounting shaft 9 and the crushing cylinder 4, wherein the two spur gears 10 mesh with each other.

[0026] In this embodiment, when using the rotating mechanism, the second servo motor 8 is started, and the second servo motor 8 drives the mounting shaft 9 to rotate. Through two meshing spur gears 10, the rotational motion of the mounting shaft 9 can be transmitted to the crushing cylinder 4, thereby driving the crushing cylinder 4 and multiple spikes 5 to rotate. The waste soil and rocks are constantly tumbling and colliding with the spikes 5 inside the crushing cylinder 4. The soil clods in the waste soil and rocks have low hardness and are broken, which improves the effect of subsequent separation of soil and rocks in the waste soil and rocks.

[0027] In a further preferred embodiment of the present invention, a plurality of guide hoppers 11 are fixedly installed at the bottom of the screening frame 2, and the plurality of guide hoppers 11 correspond to the plurality of screening mesh plates 3 respectively.

These fine water mist particles can fully contact the dust in the air, so that the dust particles are moistened and settle down, thereby achieving the purpose of dust reduction.

[0033] In a further preferred embodiment of the present invention, a baffle 17 is fixedly installed on the screening frame 2, and the baffle 17 is used to shield the dust during the screening process of waste slag and soil.
