[0038] A through groove is opened at the top end of the square frame 101, and a through groove is also opened at the front end of the square frame 101. The opening of the upper through groove ensures the addition of materials, and the opening of the front through groove ensures the observation of the material situation. The screen 102 is used to screen the materials, and the protruding part of the square frame 101 outside the screen 102 can limit the materials; the receiving plate 201 and the base 202 are used to play a supporting and connecting role; the inclined surface of the triangular block 204 has an inclination angle of 45 degrees, which ensures the inclined installation of the six-level vibration motor 205; the opening of the rectangular groove 203 can prevent the installation of the six-level vibration motor 205 from being blocked; the six-level vibration motor 205 is used to provide a vibration force; the combined structure of the first connecting column 206, the second connecting column 207 and the spring 208 can achieve a connecting role, and at the same time, the spring 208 plays an auxiliary buffering role during the up and down movement of the receiving plate 201;

[0047] This step can realize mechanized operation, thereby reducing the workload of workers and ensuring the accuracy of experimental results at the same time.

[0048] A new type of electric coal sample sieve further includes a mesh size adjustment component;

[0053] A threaded hole 305 is formed in the middle of the first rectangular plate 303, and a rectangular threaded groove 306 is formed in the middle of the second rectangular plate 304. An adjusting screw 307 is inserted between the threaded hole 305 and the rectangular threaded groove 306;

[0054] The cooperation of the above components can realize the fixation after the movement of the adjusting screen plate 302;

[0055] Working principle: Move the adjusting screen plate 302 and the first rectangular plate 303 left and right along the strip groove 301. When the mesh size is adjusted to the appropriate position, screw the adjusting screw 307 into the threaded hole 305 and the rectangular threaded groove 306;
