Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figures 1-6: a needle bar crushing device comprises a movable disc 1 and a fixed disc 2; the needle bars 3 on the movable disc 1 and the needle bars 3 on the fixed disc 2 are arranged in a staggered manner to form a crushing chamber 4; the middle part of the fixed disc 2 is provided with a feed inlet 23 which is communicated with the crushing chamber 4; the motor is in driving connection with the movable disc 1; the crushed material is thrown out through the gap between the movable disc 1 and the fixed disc 2. The needle bar 3 on the driving disk 1 and the needle bar 3 on the fixed disk 2 are arranged in a staggered clearance, the output shaft of the motor drives the driving disk 1 and the needle bar 3 on the driving disk 1 to rotate, and the needle bar 3 on the driving disk 1 and the needle bar 3 on the fixed disk 2 are mutually matched to grind and smash materials, so that the material crushing effect is achieved.

Also comprises a material containing chamber 5; the side wall of the material containing chamber 5 is provided with a door cover 51; an output shaft 52 of the motor sequentially penetrates through the side wall of the bottom of the door cover 51 and the feed inlet 23 to be connected with the movable disc 1; the side wall of the top of the door cover 51 is communicated with the feeding elbow 6; the inlet bend 6 is connected to the inlet opening 23 via a material guide channel 61. The material enters the crushing chamber 4 in the material containing chamber 5 from the feeding elbow 6 through the material guide channel 61, and then the movable disc and the fixed disc interact to grind and crush the material.

The output shaft 52 is sleeved with a shaft sleeve 521 through the end; the movable disc 1 is reversely arranged on the shaft sleeve 521 through bolts; the output shaft 52 drives the movable disc 1 to rotate through a shaft sleeve 521; the needle bars 3 on the movable disc 1 and the needle bars 3 on the fixed disc 2 continuously extrude and crush the materials, and continuously beat and beat the materials, so that the crushing effect of the materials is better; while the output shaft 52 can agitate the material in the crushing chamber 4.

The fixed disc 2 comprises a fixed cutter disc gland 21 and a fixed cutter disc 22; the fixed cutter head gland 21 is fixed on the side wall of the material guide channel 61; the fixed cutter head 22 is fixed on the fixed cutter head gland 21 through a bolt; a plurality of pinholes 221 are formed at the edge of the fixed cutter head 22; one ends of the needle bars 3 are correspondingly embedded in the needle holes 221, and the fixed cutter disc 22 is limited on the needle bars 3; therefore, the needle bar is fixed and limited on the fixed cutter disc 22, the limiting block 31 at the embedding end of the needle bar 3 is clamped between the fixed cutter disc gland 21 and the fixed cutter disc 22, and when the movable disc 1 rotates, the needle bar on the movable disc can be matched with the needle bar 3 on the fixed cutter disc 22 to crush materials.
