[0040] The driving assembly includes a first motor 102 , which is fixedly mounted on a lower portion of one side of the mixing mechanism 1 , wherein a middle portion of one side of a first gear 103 is fixedly mounted on a driving end of the first motor 102 .

[0048] Support seats 101 are fixedly installed at the four corners of the bottom end of the mixing mechanism 1.

[0049] By adopting the above technical solution, the entire device is supported.

[0050] Working principle: When in use, put the edible fungi and ingredients to be mixed into the crushing mechanism 2, start the first motor 102, so that the two first gears 103 rotate, thereby driving the transmission belt 1031 to rotate, thereby driving the second gear 202 to rotate, that is, driving the two crushing rollers 201 to rotate relative to each other, so as to crush the internal edible fungi and ingredients entering the crushing mechanism 2, and at the same time drive the half-face gear 205 to rotate, so as to drive the tooth plate 204 to move up and down reciprocatingly, and then drive the push plate 2041 to move up and down inside the dust collection pipe 206;

[0051] When the push plate 2041 moves downward, the first check valve 2071 is closed and the dust enters the dust collection pipe 206 through the second check valve 2072. When the push plate 2041 moves upward, the second check valve 2072 is closed, and the first check valve 2071 is opened, so that the dust enters the collection bin 207, thereby repeatedly performing dust reduction treatment on the dust generated during the crushing process.

[0052] After the edible fungi and ingredients are crushed by the crushing roller 201, the edible fungi and ingredients fall to the top of the screening plate 4. By starting the second motor 4031, the rotating shaft 405 is driven to rotate, so that the eccentric block 4051 rotates. Under the centrifugal rotation of the eccentric block 4051, the screening plate 4 moves up and down, so that the edible fungi and ingredients that fall to the top of the screening plate 4 can be screened, and the impurities and incompletely crushed edible fungi and ingredients are prevented from falling into the inside of the mixing mechanism 1, affecting the mixing of the edible fungi and ingredients. Large pieces of edible fungi and ingredients are discharged through the second discharge port 409;

[0053] When the rotating shaft 405 rotates, the third gear 404 rotates, thereby driving the fourth gear 406 to rotate, thereby driving the reciprocating screw rod 407 to rotate, that is, driving the sliding block 4071 used in conjunction with each other to rotate, so that the cleaning brush 408 reciprocates on the top of the screen plate 4, thereby preventing the screen plate 4 from being blocked and affecting normal use;

[0054] When the two first gears 103 rotate, the two spiral stirring blades 104 used in conjunction with each other can be rotated, so that the edible fungi and the ingredients are fully mixed under the transmission and stirring of the spiral stirring blades 104 and finally discharged from the first discharge port 105.

[0055] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
