[0055] like Figures 1 to 12As shown, in this embodiment, the heat dissipation structure 700 includes a heat dissipation housing 701. The top of the support base 204 supports the bottom of the heat dissipation housing 701 and is connected to it. The heat dissipation housing 701 has an installation cavity. A rotating shaft 702 is rotatably arranged in the installation cavity. Heat dissipation blades 703 are arranged on the rotating shaft 702. An air inlet 704 communicating with the installation cavity is opened on the side of the heat dissipation housing 701 near the crushing structure 100. The output end of the heat dissipation channel 112 is connected to the air inlet 704. A filter vertical plate 705 is arranged in the air inlet 704.

[0056] The hydraulic telescopic rod 401 is driven, and the telescopic end of the hydraulic telescopic rod 401 pushes the entire crushing structure 100 to slide along the length direction of the guide groove 303 of the sliding bracket 300 (the first transition channel 200 moves synchronously with the crushing structure 100). When the first transition channel 200 is located on the left side, the output port of the first transition channel body 201 is located at the receiving port on the left side of the sliding bracket 300, thereby realizing the connection between the output port of the first transition channel body 201 and the receiving port on the left side of the sliding bracket 300; when the first transition channel 200 is located on the right side, the output port of the first transition channel body 201 is located at the receiving port on the right side of the sliding bracket 300, thereby realizing the connection between the output port of the first transition channel body 201 and the receiving port on the right side of the sliding bracket 300; wherein, the bottom surface of the output port of the first transition channel body 201 may be provided with a groove, and a sealing ring is fixedly bonded in the groove, thereby increasing the sealing performance after the output port of the first transition channel body 201 is connected to the receiving port on the right side of the sliding bracket 300.

[0057] like Figure 3As shown, when Daqu (a type of Chinese liquor) is fed, the drive motor is started, causing the baffle shaft 604 to rotate, which in turn causes the baffle 605 to rotate counterclockwise. On the one hand, this facilitates the Daqu feeding into the feeding channel body 601 until it passes through the second transition channel 800 and reaches the crushing structure 100. On the other hand, when the baffle 605 rotates to the position of the flip plate 603, because the baffle 605 is made of flexible material, it will bend when it comes into contact with the lower surface of the flip plate 603. After the baffle 605 continues to rotate, it pushes the flip plate 603 to flip upward until the baffle 605 rotates out from the lower surface of the flip plate 603. Before rotating out, the baffle 605 will consistently come into contact with the lower surface of the flip plate 603 to form a shield, thereby achieving a sealed treatment of the inlet of the feeding channel body 601 and reducing the excessive dust generated by the crushing of Daqu after it is fed into the crushing structure 100 from escaping from the inlet of the feeding channel body 601.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
