When in use, materials are put in from a hopper of the feeding assembly 2, the materials enter a grinding cavity formed by the grinding ring 9 on the right rotary drum 7 and the grinding drum 6 through the feeding pipe 21, the motor 11 is started, the motor 11 drives the belt pulley 12 to rotate, the belt pulley 12 drives the shaft sleeve connected on the right rotary drum 7 to rotate through the belt 13, the shaft sleeve drives the right rotary drum 7 to rotate, the large helical gear 14 and the small helical gear 15 on the right rotary drum 7 are meshed to drive the small helical gear 15 to rotate, the small helical gear 15 and the large helical gear 14 on the left rotary drum 8 are meshed to drive the left rotary drum 8 to rotate in the reverse direction, at this time, the grinding rings 9 on the left rotary drum 8 and the right rotary drum 7 and the cross-shaped bulges 64 on the inner wall of the grinding drum 6 grind and crush the materials entering the annular grinding cavity, as shown in figure 12, the annular grinding cavity is high on the left and low, the annular grinding cavity is wide and narrow on the right, and in the material grinding process, under the action of all the pressure springs 92, all the grinding rings 9 are located on the leftmost side of the spiral guide groove where the grinding rings are located, when materials thrown into the annular grinding cavity generate small friction resistance on the grinding rings (namely the materials are very low in hardness and are crisp, and the quantity of the materials at the position is small), the grinding rings 9 cannot move at this time, the materials are normally ground, the ground materials can move to the leftmost side of the annular grinding cavity, namely the lowest end of the annular grinding cavity and then fall into the barrel body 31 of the screening assembly 3, the materials falling into the barrel body 31 can be screened by the screening net 32 and divided into qualified materials and unqualified materials, the qualified materials can fall into the lower side of the screen plate 32 and are led out through the qualified material outlet 34, otherwise, the unqualified materials are led out through the unqualified material outlet 33 and collected after the unqualified materials are led out, during the operation of the device, material returning treatment is carried out from the material returning hopper 4, namely, the materials enter the annular grinding cavity through the first blanking hole 611 and the second blanking hole 69 on the material returning hopper 4 to be ground again It should be noted that, when the material put into the annular grinding chamber generates a large frictional resistance to the grinding ring 9 at a certain position in the annular grinding chamber (i.e. the material amount is large and the material is hard), the frictional resistance is enough to overcome the elastic force of the compression spring 92, but not enough to overcome the torsion force generated by the torsion spring 51 to the grinding cylinder 6, at this time, the grinding ring 9 lags behind the rotation of the left rotary cylinder 8 and the right rotary cylinder 7, i.e. all the grinding rings 9 need to move to the right along the spiral guide groove from the initial position, until the material is ground, the resistance is reduced, the elastic force of the compression spring 92 pushes the grinding ring 9 to the original position, i.e. to the left along the spiral guide groove, wherein the material can be moved to any place depending on the resistance of the material to the grinding ring 9, therefore, the process of moving the grinding ring 9 to the right and then moving left is repeated during the whole grinding process, and the left-right reciprocating process of the grinding ring 9 can generate a certain action and transverse direction to the material in the annular grinding chamber The grinding effect prevents material from piling and blocking, and enhances the grinding effect.

When it appears that the material creates a great frictional resistance against the grinding ring 9 at a certain position on the right drum 7, and all the grinding rings 9 on the right rotary drum 7 are moved to the extreme position along the spiral guide groove, so that the proportion of large materials in the input materials is large (namely the large materials are more), the annular grinding cavity formed between the grinding ring 9 on the left rotary drum 8 and the grinding drum 6 is less in contact with the materials, in this case, the frictional resistance is sufficient to overcome the torsion force of the torsion spring 51 to the grinding drum 6, thereby rotating the grinding drum 6 counterclockwise, i.e., the grinding vessel 6 rotates along the spiral groove 55 and moves to the right, thereby increasing the grinding gap formed by the grinding ring 9 on the right rotary vessel 7 and the grinding vessel 6, meanwhile, the adaptation grade of the annular grinding cavity to materials with different sizes is improved, so that all the grinding rings 9 in the annular grinding cavity can contact more materials; on the contrary, when the material generates a large frictional resistance to the grinding ring 9 at a certain position on the left rotary drum 8, and all the grinding rings 9 on the left rotary drum 8 have moved to the limit position (i.e. the small material is more) along the spiral guide groove, the grinding ring 9 on the right rotary drum 7 has contacted little material, in this case, the frictional resistance to the grinding drum 6 by the material is enough to overcome the torsion force generated to the grinding drum 6 by the torsion spring 51, so that the grinding drum 6 rotates clockwise, i.e. the grinding drum 6 rotates and moves left along the spiral groove 55, thereby reducing the grinding gap formed by the grinding ring 9 on the left rotary drum 8 and the grinding drum 6, and simultaneously reducing the adaptation grade of the annular grinding cavity to the materials with different sizes, so that all the grinding rings 9 of the annular grinding cavity can contact more materials, thereby adjusting the size of the grinding gap of the annular grinding cavity according to the material proportion, thereby improving the grinding efficiency of the mixed materials.

Specifically, the returning materials are also simultaneously carried out in the grinding process, when the grinding cylinder 6 moves to the right, the blanking position of the returning hopper 4 also moves to the right, the outlet of the returning hopper 4 is staggered with the first blanking hole 611, so that the blanking efficiency of the first blanking hole 611 is reduced, the grinding resistance of the returned materials to the annular grinding cavity is reduced, the blanking position of the returning hopper 4 is changed, so that the returned materials are prevented from being excessively ground, when the grinding cylinder 6 moves to the right, the grinding gap of the annular grinding cavity is enlarged, at the moment, the discharging quality is also deteriorated, namely the diameter of the returned materials is increased, the blanking position of the returning hopper 4 moves to the right, so that the returned materials fall into the position with larger grinding gap through the first blanking hole 611 and the second blanking hole 69, on the contrary, when the grinding cylinder 6 moves to the left, the grinding gap in the annular grinding cavity is reduced, at the moment, the discharging quality is improved, the diameter of the returned material is also reduced, the left movement of the blanking position of the return hopper enables the returned material to be moved to the position with a smaller grinding gap, namely the change of the blanking position of the return hopper 4, the purpose of conveying the larger returned material to the position with a larger gap and conveying the smaller returned material to the position with a smaller gap is achieved, the stroke (or time) of the material passing through the grinding cavity is increased or reduced, the materials with different sizes can be accurately conveyed to the proper gap position in the material returning process, the grinding efficiency of the returned material is improved, and over grinding is prevented.

In summary, according to the grinding device for detecting animal samples provided by the embodiments of the present invention, the driving assembly drives the right rotary drum and the left rotary drum to rotate in opposite directions, and according to the ratio of the materials entering the annular crushing cavity, the grinding rings on the right rotary drum and the left rotary drum can move along the spiral guide groove, so that the materials generate friction resistance to the grinding rings and the grinding drum, and further the grinding drum rotates along the spiral groove and moves left or right, so that the grinding gap of the annular grinding cavity is increased or decreased, thereby improving the grinding efficiency of the mixed materials; meanwhile, frictional resistance generated between the materials and the grinding rings can enable all the grinding rings to move rightwards from the initial positions along the spiral guide grooves, after the materials are ground, the grinding rings can move leftwards along the spiral guide grooves under the action of elastic force of a pressure spring, and in the whole grinding process, the grinding rings reciprocate leftwards and rightwards along with rotation of a certain angle to generate a certain derivation effect and a certain transverse grinding effect on the materials in the annular grinding cavity, so that material accumulation and jamming are prevented, and the grinding effect is enhanced; simultaneously, in the grinding process, because the removal of grinding vessel, can lead to the change in grinding clearance, thereby lead to the change of grinding quality, it is further, on this basis, set up the anti-hopper, through the change of the blanking position of returning the hopper, realized sending the great material of returning to the great position in clearance, send the less material of returning to the less position in clearance, increase or reduce the stroke that the material passes through at annular grinding chamber, make the material of equidimension not can be accurate send to suitable clearance position at the material returning in-process, improve the grinding efficiency of returning the material, prevent the over-grinding, therefore, the clothes hanger is strong in practicability, and is worth promoting.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
