[0024] The cooling mechanism 14 includes an air supply channel 141 arranged in a surrounding manner in the side wall of one end of the circular tube II9, an air inlet channel 142 connected to the air supply channel 141 is axially arranged in the side wall of the circular tube II9, a circular hole 143 connected to the air inlet channel 142 is arranged on one side wall of the cold air box 13, a plurality of cooling channels I144 connected to the air supply channel 141 are arranged in the side wall of the rotating crushing barrel 3 along its length direction, one end of the cooling channel I144 is connected to the internal opening of the circular tube I8, a cooling channel II145 penetrating the impact column 6 and extending to the outside of another group of rotating shafts 10 is arranged on the rotating shaft 10 in the circular tube I8, the cooling channel II145 in the impact column 6 is spirally arranged, and a circle of annular grooves 146 corresponding to the end of the cooling channel I145 are also arranged on the rotating shaft 10 in the circular tube I8, and the annular groove 146 is provided with a through hole 147 connected to the cooling channel II145.

[0025] The transmission mechanism 12 includes an annular seat 121 arranged at the end of a circular tube 18, an inner gear ring 122 is arranged on one side of the annular seat 121, an outer gear ring 123 located in the opening of the inner gear ring 122 is arranged at the end of the rotating shaft 10, a gear 124 meshing with the inner gear ring 122 and the outer gear ring 123 is arranged between the inner gear ring 122 and the outer gear ring 123, the gear 124 is fixed to the corresponding L-shaped plate 11 through a fixed shaft 125, and a bearing I for fixing the fixed shaft 125 is arranged on the L-shaped plate 11.

[0026] In this embodiment, the rotating shaft 10 is adapted to the internal opening size of the corresponding circular tube I8 and the circular tube II9, the bracket 2 is provided with a bearing II for fixing the corresponding circular tube I8 and the circular tube II9, and the L-shaped plate 11 is provided with a bearing III for fixing the rotating shaft 10.

[0027] The driving device 4 includes a motor 41, and pulleys are correspondingly arranged on the output shaft of the motor 41 and the round tube II9, wherein two sets of pulleys are connected by a transmission belt 42.

[0028] like Figure 2 , 4 As shown, one end of the rotating shaft 10 passes through the circular hole 147 and the corresponding side wall of the cold air box 13 in sequence, the inner diameter of the circular hole 147 is larger than the diameter of the rotating shaft 10, and the inner diameter of the circular hole 147 is smaller than the diameter of the circular tube II9.

[0029] In this embodiment, the protrusion 7 is in the shape of a triangular pyramid, and a metal shell 15 matching it is covered on the protrusion 7. An elastic member connected to the inner wall of the shell 15 and suspending it is provided on the outer wall of the protrusion 7. The bottom of the shell 15 is connected to the outer wall of the corresponding impact column 6 and the inner wall of the rotating crushing barrel 3 through an elastic band.

[0030] The method of using the present invention is as follows: the raw material is introduced into the rotating crushing barrel 3, the motor 41 drives the round tube II9 and the round tube I8 to rotate on the L-shaped plate 11 through the transmission belt 42, and then drives the rotating crushing barrel 3 to rotate, and at the same time, the rotating round tube I8 drives the rotating shaft 10 and the impact column 6 to rotate through the annular seat 121, the inner gear ring 122, the gear 124 and the outer gear ring 123. At this time, the impact column 6 rotates in the opposite direction to the rotating crushing barrel 3. In this process, the impact column 6 and the rotating crushing barrel 3 are driven by the driving device to rotate in different directions, wherein the rotating crushing barrel 3 drives the material inside it to rotate, so that the material fully collides with the impact column 6 and the different end faces of the rotating crushing barrel 3, and when the material collides with the impact column 6 and the protrusion 7, the material can be broken by utilizing the brittleness of the material, and the broken material will rebound to the inner wall of the rotating crushing barrel 3, and the material can reciprocate between the rotating crushing barrel 3 and the impact column 6 with the rotation, thereby achieving the crushing of the material into fine particles.

[0031] In the above process, the materials repeatedly bounced in the rotating crushing barrel 3 under the influence of the rotating force frequently contact and collide with the protrusions 7 on the inner wall of the rotating crushing barrel 3 and the outer wall of the impact column 6, thereby squeezing the shell 15 and compressing the elastic member. When the elastic member stretches, the rebound force generated can exert a large rebound force on the raw materials in contact with it through the shell 15, so that the raw materials can fully reciprocate and collide between the rotating crushing barrel 3 and the impact column 6.

[0032] At the same time, the cold gas is injected into the cold air box 13. At this time, the circular tube II9 rotates under the influence of the driving device, and the air inlet channel 142 on the rotating circular tube II9 is ​​always connected with the circular hole 143. Then, the cold air flow in the cold air box 13 can enter the air supply channel 141 through the air inlet channel 142, and then flow through the cooling channels I144 on the outer wall of the rotating crushing barrel 3 to cool its side wall. At the same time, the part of the gas is recovered and enters the annular groove 146 from the outlet end of the cooling channel I144, and then enters the cooling channel II145 from the annular groove 146 and the through hole 147 to cool down the side wall. The impact column 6 is cooled and finally discharged. In the above process, when the rotating shaft 10 rotates, the annular groove 146 is driven to rotate, but the annular groove 146 is always connected to the cooling channel I144 at this time, so that the cold air flow can be continuously introduced into the annular groove 146 and flow into the cooling channel II145 through the through hole 147. The present invention can introduce the cold air flow into the rotating crushing barrel 3 and the impact column 6 during the rotation of the equipment to process the material, and then cool them down in turn, so as to make full use of the cold air in the cold gas to cool the above equipment and prevent energy waste.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
