[0011] After adopting the above technical solution, the beneficial effects of the utility model are:

[0012] (1) In the present application, the weighed edible fungus culture matrix raw materials are added into the material sieve, and the small particles of the material can pass through the screen at the bottom of the material sieve and fall down into the mixing barrel, while the large particles of the material will stay on the top of the screen, which can improve the processing quality of the edible fungus culture matrix;

[0013] (2) In the present application, when the central shaft stirs the small particles in the mixing barrel through the stirring rod, the eccentric wheel at the upper end of the central shaft drives the mounting frame and the material screen to move back and forth, thereby accelerating the small particles in the material screen to fall downward through the screen, thereby improving the efficiency of separating large particles from small particles;

DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown, the mixing equipment of edible fungus culture matrix includes a mixing barrel 1, which is cylindrical with an open upper end. The mixing barrel 1 is fixedly mounted on a base plate 3 by four supporting columns 2. A discharge port 4 is provided on one side of the bottom of the mixing barrel 1. A closing plate 5 is detachably mounted on the end of the discharge port 4 away from the mixing barrel 1. In the present embodiment, the closing plate 5 is mounted on one end of the discharge port 4 by bolts. In addition, the closing plate 5 can also be mounted on the discharge port 4 by a hinged or clamped manner, so that the material in the mixing barrel 1 can be discharged after the closing plate 5 is opened.

[0022] A central shaft 7 driven to rotate by a motor 6 is provided in the mixing barrel 1. The central shaft 7 is coaxially arranged with the mixing barrel 1. The central shaft 7 is rotatably mounted on the bottom wall of the mixing barrel 1 through a bearing. The motor 6 is mounted on the bottom plate 3 through bolts. A small pulley 8 is fixedly mounted on the rotating shaft of the motor 6. The lower end of the central shaft 7 extends out of the mixing barrel 1 and a large pulley 9 is fixedly mounted. A belt 10 is connected between the small pulley 8 and the large pulley 9. A plurality of stirring rods 11 arranged evenly are welded on the central shaft 7 in the mixing barrel 1. The stirring rods 11 extend radially along the central shaft 7. When the motor 6 is working, the small pulley 8 is driven to rotate, and then the small pulley 8 drives the large pulley 9 and the central shaft 7 to rotate through the belt 10. When the central shaft 7 rotates, the material in the mixing barrel 1 is stirred through the stirring rod 11.

[0023] A mounting frame 12 is installed in a horizontal sliding manner in the mixing barrel 1 located above the central axis 7, and a material screen 13 is detachably installed in the mounting frame 12. Specifically, the mounting frame 12 includes an annular plate 14 extending vertically along the axis, and a support plate 15 extending radially forward and backward is fixedly installed at the bottom of the annular plate 14 by bolts. When the material screen 13 is installed in the mounting frame 12, the support plate 15 can provide support for the material screen 13. A sliding rod 16 extending left and right is fixedly installed in the mixing barrel 1 by bolts, and two sliding rods 16 are arranged side by side in front and back. A sliding seat 17 matching the sliding rod 16 is fixedly installed at the bottom of the support plate 15, and the sliding seat 17 is slidably sleeved on the corresponding sliding rod 16. When the mounting frame 12 slides left and right laterally, the sliding rod 16 can provide support and guidance for the mounting frame 12.

[0024] The material screen 13 includes an annular side plate 18 , the outer diameter of the side plate 18 matches the inner diameter of the annular plate 14 , which can reduce the margin of movement of the material screen 13 in the mounting frame 12 , and a screen 19 is welded inside the lower end of the side plate 18 .

[0025] In order to facilitate the taking and placing of the material screen 13 , two ear plates 24 arranged opposite to each other on the left and right are welded to the outer side of the side plate 18 .

[0026] In order to prevent the material screen 13 from falling off the mounting frame 12 during the screening process and to improve the convenience of disassembly and assembly of the material screen 13, a vertically extending screw rod 20 is welded to the top of the annular plate 14. The screw rod 20 corresponds one-to-one to the ear plate 24. The ear plate 24 is provided with a through hole for the corresponding screw rod 20 to pass through. A butterfly nut 21 is screwed on the screw 20 for tightening the ear plate 24.

[0027] An eccentric wheel 22 is fixedly mounted on the upper end of the central shaft 7, and a long strip groove 23 is integrally formed at the bottom of the support plate 15. The width direction of the long strip groove 23 extends left and right along the sliding direction of the mounting frame 12, and the width of the long strip groove 23 is consistent with the diameter of the eccentric wheel 22. When the eccentric wheel 22 rotates, it acts on the left and right side walls in the width direction of the long strip groove 23 and drives the mounting frame 12 to move back and forth laterally.

[0028] When in use, first place the material screen 13 in the mounting frame 12, and make the two screws 20 pass through the through holes on the corresponding ear plates 24 respectively, then screw the butterfly nut 21 on the screw 20 and tighten it, and press the ear plates 24 by the butterfly nut 21, so that the material screen 13 cannot be separated from the mounting frame 12; add the weighed edible fungus culture matrix raw materials into the material screen 13, and the small particles of material can pass through the screen 19 at the bottom of the material screen 13 and fall down into the mixing barrel 1, and the large particles of material will stay on the top of the screen 19, thereby realizing the separation of large particles and small particles, and improving the processing quality of the edible fungus culture matrix; start the motor 6, the motor 6 drives the central shaft 7 to rotate, and the central shaft 7 stirs the small particles of material falling into the mixing barrel 1 through the stirring rod 11 The eccentric wheel 22 at the upper end of the central shaft 7 is driven to rotate, and the eccentric wheel 22 acts on the long groove 23 and drives the mounting frame 12 to move back and forth along the slide bar 16, and then the mounting frame 12 drives the material screen 13 to move back and forth, thereby accelerating the small particles in the material screen 13 to pass through the screen 19 and fall downward, thereby improving the efficiency of separating large particles from small particles; finally, after the materials falling into the mixing barrel 1 are completely mixed, the closing plate 5 on the discharge port 4 is opened, so that the processed edible fungus culture matrix in the mixing barrel 1 is discharged through the discharge port 4, and then the butterfly nut 21 is unscrewed to remove the material screen 13 from the mounting frame 12 to clean the large particles remaining in the material screen 13.
