[0026] like Figure 1 、 Figure 2 and Figure 4 As shown, the embodiment of the present invention provides a device for detecting the gradation of a solidifying agent-stabilized coal gangue mixture, comprising: a detection box 1, a feed pipe 101 fixedly connected to the top of the detection box 1, and a screening assembly 2 provided in the detection box 1; the screening assembly 2 comprises a movable plate 201 slidably connected to the inner wall of the detection box 1, a spring 202 for providing elastic force fixedly mounted on the top of the movable plate 201, an electromagnetic vibrator 203 for providing vibration effect fixedly mounted on the top of the spring 202, and a screening box 204 for screening coal gangue fixedly mounted on the top of the electromagnetic vibrator 203; the movable plate 201 is close to the inner wall of the detection box 1, and the screening assembly 201 is slidably connected to the inner wall of the detection box 1, and the spring 202 fixedly mounted on the top of the movable plate 201 is fixedly mounted on the top of the spring 202 A circular groove 205 is provided on one side of the outer wall of the detection box 1, and the inner wall of the circular groove 205 is fixedly equipped with a spring 206 that provides elastic force, the top of the spring 206 is fixedly equipped with a connecting block 207, the top of the connecting block 207 is fixedly equipped with a clamping block 208, and the outer wall of the connecting block 207 is fixedly equipped with a pull ring 209, which passes through the movable plate 201, and the cross-sectional shape of the clamping block 208 is a right-angled trapezoid, and the hypotenuse of the clamping block 208 is located on the side close to the screening box 204. By limiting the clamping block 208, it is beneficial to improve the smoothness of the movable plate 201 during installation and the firmness during mobile clamping.

[0027] like Figure 2 and Figure 3 As shown, the inner wall of the detection box 1 is fixedly equipped with a guide frame 102, which is located on the top of the screening box 204. By setting the guide frame 102, it is helpful to guide the coal gangue falling into the detection box 1 and ensure that it falls into the screening box 204.

[0028] like Figure 2 and Figure 4 As shown, a bellows 210 is fixedly mounted on the top of the movable plate 201, the top of the bellows 210 is fixedly connected to the bottom of the electromagnetic vibrator 203, and the spring 1 202 is located inside the bellows 210. By providing the bellows 210, it is beneficial to protect the spring 1 202 and prevent the gangue from wearing the outer wall of the spring 1 202, thereby affecting the service life of the spring 1 202.
