A second cavity 9 and a third cavity 10 are opened inside the screening housing 7, a first through hole 12 is opened between the first cavity 8 and the second cavity 9, and the first A second through hole 13 is opened between the second cavity 9 and the third cavity 10, and the material can be screened through the first through hole 12 and the second through hole 13. The top of the screening shell 7 is screwed with The top cover 11, the top cover 11 can seal the housing 7;
[0023] The side wall of the housing 2 is fixedly connected with a second motor 14, the output end of the second motor 14 is sleeved with a second output shaft, the end of the second output shaft is fixedly connected with a cutting shaft 15 and the surface of the cutting shaft 15 A number of blades 16 are fixedly connected, and the blades 16 can shred materials. The end of the cutting shaft 15 is sleeved with a first bearing 17, and the first bearing 17 is embedded in the inner side wall of the housing 2. The bottom of the cutting shaft 15 A partition 21 is provided. The partition 21 can block the material when the material is shredded. The bottom of the partition 21 is provided with an inclined plate 18, and the inclined plate 18 is fixed to the side wall of the casing 2. The number of the inclined plate 18 There are two, and a first gap is formed between the two inclined plates 18, and the material can enter between the two rollers 19 through the first gap. 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.
