The bottom of the inclined plate 18 is provided with two rollers 19, and two rollers A second gap is formed between the wheels 19, and the first grinding of the material can be carried out by two grinding wheels 19, a third motor 23 is fixedly connected to the side wall of the housing 2, and the output end of the third motor 23 is sleeved The rotating shaft 20 is sleeved with a second bearing 25 at the end of the rotating shaft 20, and the second bearing 25 is inlaid on the inner side wall of the housing 2. The rotating shaft 20 is sleeved with the roller 19, and the bottom of the roller 19 is provided with a fixing block 22 , The fixed block 22 and the two rollers 19 form two third gaps, the material between the two rollers 19 and the fixed block 22 can be secondly milled, and the width of the third gap is smaller than the width of the second gap.
[0024] As a technical optimization solution of the present invention, the cross section of the fixed block 22 is an isosceles triangle structure, and the fixed block 22 is fixedly connected to the inner side wall of the housing 2, and the two grinding wheels 19 and the fixed block 22 allow the material to pass through after grinding. The third gap enters the hopper 3.
[0025] As a technical optimization solution of the present invention, the inner side wall of the housing 2 is provided with a card slot, and the card slot is engaged with the partition 21, and the partition 21 penetrates the side wall of the housing 2 to facilitate the partition 21 The drawing out facilitates the material to fall on the inclined plate 18.
[0026] As a technical optimization solution of the present invention, the aperture of the second through hole 13 is smaller than the aperture of the first through hole 12, and the second through hole 13 is in communication with the second cavity 9 and the third cavity 10, so that Materials of different sizes enter the second cavity 9 and the third cavity 10 for aggregation.
[0027] As a technical optimization solution of the present invention, the number of the electric push rods 4 is two, and the electric push rods 4 are fixed to the bottom plate 24, and the electric push rods 4 can drive the screening housing to move in the vertical direction.
[0028] As a technical optimization solution of the present invention, the hopper 3 has a conical structure, and the bottom of the hopper 3 is provided with a leakage opening, and the material can enter the first cavity 8 through the leakage opening at the bottom of the hopper 3.
[0029] As a technical optimization solution of the present invention, the first cavity 8 and the second cavity 9 are both in communication with the first through hole 12, and the top of the first cavity 8 has an open end, and the first cavity 8 passes through The first through hole 12 can allow materials smaller than the first through hole 12 to enter the second cavity 9 and gather.
[0030] As a technical optimization solution of the present invention, the second cavity 9 and the third cavity 10 are both annular structures, which can facilitate the screening of materials in the second cavity 9 and the third cavity 10 by centrifugal force.
[0031] When the present invention is in use, the electrical components in the device are externally connected to power supply and control switches, and materials are poured from the top of the housing 2, the second motor 14 drives the cutting shaft 15 to rotate through the second output shaft, and the material is initially cut through the blade 16. After crushing and shredding, the partition 21 is extracted, the material enters the second gap between the two grinding wheels 19 through the inclined plate 18, and the grinding wheel 19 drives the material through the third motor 23 to grind the material, and the ground material enters In the third gap, the fixed block 22 cooperates with the rotation of the roller 19 to grind the material a second time, and then the material enters the hopper 3, enters the first cavity 8 from the leakage port, and the first motor 6 passes through the first output shaft Drive the sieving housing 7 to rotate. Under the action of centrifugal force, the material in the first cavity 8 is screened into the second cavity 9 through the first through hole 12, and the material in the second cavity 9 passes through the second cavity. The through holes 13 are screened into the third cavity 10, so that materials of different sizes are collected in the first cavity 8, the first cavity 9 and the first cavity 10 respectively. After the screening is completed, the electric push rod 4 contracts, Keep the screening shell 7 away from the hopper 3, unscrew the top cover 11, and take out materials from the first cavity 8, the second cavity 9 and the third cavity 10.
