[0026] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] As Figure 1-8 shown, the assembly assembly of the hopper of this grinder includes a hopper seat 1 and a hopper 2 for storing and grinding materials. A bin lock 3 that can rotate relative to the hopper 2 and has a first locking position 31 is provided on the hopper 2. A seat lock 4 with a second locking position 41 and a transmission member 5 for driving the bin lock 3 to rotate are provided on the hopper seat 1; When the hopper 2 is installed on the hopper seat 1, the hopper 2 and the bin lock 3 move forward toward the hopper seat 1. The operator realizes the forward movement of the hopper 2 by pushing the hopper 2 toward the hopper seat 1. As Figure 1 , 2 shown, in this embodiment, the hopper 2 is assembled onto the hopper seat 1 from the lower part of the hopper seat 1. Therefore, in this embodiment, the forward movement should be interpreted as upward movement. The first locking position 31 passes from the outside of the second locking position 41 through the second locking position 41 (the first locking position 31 moves from the head end of the second locking position 41 to the tail end of the second locking position 41. In this embodiment, the head end of the second locking position 41 should be understood as the lower part of the second locking position 41, and the tail end of the second locking position 41 should be understood as the upper part of the second locking position 41). Then the bin lock 3 contacts the transmission member 5 and drives the bin lock 3 to rotate, so that the first locking position 31 corresponds to the second locking position 41. After the bin lock 3 moves backward in the reverse direction (in this embodiment, moving backward in the reverse direction should be interpreted as downward movement. When the operator no longer pushes the hopper 2, the hopper 2 moves backward in the reverse direction), the first locking position 31 and the second locking position 41 are locked and matched, realizing the quick installation of the hopper 2 and the hopper seat 1; when the hopper 2 and the hopper seat 1 are disassembled, the hopper 2 and the bin lock 3 move forward, so that the first locking position 31 is away from the second locking position 41. Then the bin lock 3 contacts the transmission member 5 and drives the bin lock 3 to rotate, so that the first locking position 31 is misaligned with the second locking position 41, so that the first locking position 31 can move from the tail end of the second locking position 41 to the head end of the second locking position 41 through backward movement in the reverse direction, and the hopper 2 can be removed from the hopper seat 1 in the reverse direction, realizing the quick disassembly of the hopper 2 and the hopper seat 1.

[0028] In the present invention, the quick disassembly and assembly of the silo 2 and the silo base 1 can be achieved by the forward and reverse movement of the silo 2, which is convenient for users. In addition, only the silo locking member 3 is configured on the silo 2, and the base locking member 4 and the transmission member 5 are configured on the silo base 1, which is beneficial to reducing the number of accessories on the silo 2, simplifying the structure of the silo 2 and reducing the weight of the silo 2, thus facilitating the use of the silo 2 by users.

[0029] In some embodiments of the present invention, such as Figure 3 , 4 As shown, after the silo 2 and the silo base 1 are installed, the transmission member 5, the silo locking member 3, and the base locking member 4 are arranged in sequence along a straight line direction. When the silo 2 and the silo base 1 are disassembled, the silo locking member 3 on the silo 2 can cooperate with the transmission member 5 through forward movement.

[0030] In some embodiments of the present invention, such as Figure 1 , 2 As shown in FIGS. 6 and 7, the number of the first locking positions 31 and the second locking positions 41 is several and they are arranged at intervals in the circumferential direction. An entry slot 42 for one first locking position 31 to pass through is left between two adjacent second locking positions 41. The entry slot 42 is provided to guide the first locking position 31 to pass through the second locking position 41 from the side of the second locking position 41. A first guiding inclined portion 43 for guiding the first locking position 31 to turn into the entry slot 42 is provided at the head end of the second locking position 41. When the first locking position 31 moves forward, even if the head end of the second locking position 41 blocks the advancing path of the first locking position 31, the first locking position 31 can still be guided to rotate and fall into the entry slot 42 through the contact and cooperation between the first locking position 31 and the first guiding inclined portion 43. A locking slot 44 connected to one side of the end of the entry slot 42 is provided on the second locking position 41. A first inclined portion 441 that cooperates with each other is respectively provided at the bottom of the locking slot 44 and the first locking position 31. The first inclined portion 44 is provided to limit the first locking position 31 from disengaging from the locking slot 44 and avoid the loosening of the first locking position 31 and the second locking position 41 without human intervention. The height of the first inclined portion 441 gradually decreases from the side where the locking slot 44 is connected to the entry slot 42 to the side away from the entry slot 42. A second guiding inclined portion 45 located above the locking slot 44 is provided at the end of the second locking position 41. The second guiding inclined portion 45 and the entry slot 42 are respectively located on both sides of the locking slot 44. When the silo 2 and the silo base 1 are disassembled and the first locking position 31 moves backward, even if the first locking position 31 has a slight deviation and contacts the end of the second locking position 41, the first locking position 31 can still be guided to turn into the corresponding entry slot 42 through the action of the second guiding inclined portion 45, realizing the disassembly of the silo 2 and the silo base 1. In this embodiment, the first locking position 31 passes forward through the entry slot 42 on the side of the second locking position 41 close to the locking slot 44 and exits backward through the entry slot 42 on the side of the second locking position 41 away from the locking slot 44. The height of the second guiding inclined portion 45 gradually decreases from the side close to the locking slot 44 to the side away from the locking slot 44.

[0031] In some embodiments of the present invention, such as Figure 1 and 2 As shown in Figures 6 and 7, the first locking position 31 and the second locking position 41 are respectively bumps provided on the bin locking member 3 and the seat locking member 4. The form of the bumps facilitates the cooperation between the bin locking member 3 and the bin seat 1.

[0032] The first locking position 31 and the transmission member 5 are respectively provided with a first inclined surface portion 32 that cooperate with each other and are used to drive the bin locking member 3 to rotate. The setting of the first inclined surface portion 32 is used to adjust the circumferential position of the first locking position 31. On the side of the transmission member 5 opposite to the second locking position 41, there are a plurality of tooth portions 51 arranged in sequence along the circumference. The side of the tooth portion 51 opposite to the second locking position 41 constitutes the first inclined surface portion 32.

[0033] In some embodiments of the present invention, such as Figure 1 and 3 As shown in Figures 4 and 7, an elastic mechanism is provided on the bin seat 1. Before the bin locking member 3 moves forward and contacts the transmission member 5, it first contacts and drives the elastic mechanism to move forward. When the bin locking member 3 contacts the elastic mechanism, the elastic mechanism exerts a reverse force on the bin locking member 3. In this case, when the bin locking member 3 and the bin 2 are not driven forward and released, the elastic mechanism drives the bin locking member 3 and the bin 2 to move backward. The setting of the elastic mechanism prevents the bin locking member 3 from contacting the transmission member 5 and causing the rotation of the bin locking member 3 without human intervention.

[0034] The elastic mechanism includes a moving member 61 provided in the bin seat 1 and used for contacting and cooperating with the bin locking member 3, and a first spring 62 provided between the bin seat 1 and the moving member 61. An interval for the forward and backward reciprocating movement of the moving member 61 is provided in the bin seat 1. The moving member 61 is located outside the transmission member 5.

[0035] In some embodiments of the present invention, such as Figure 1 and 3 As shown in Figures 4 and 7, the bin seat 1 is provided with a driving device 71. A coupling structure is provided between the bin seat 1 and the bin 2 so that after the bin seat 1 and the bin 2 are installed, the driving device 71 drives the bin 2 to grind powder through the coupling structure; The coupling structure includes a seat coupling 72 provided on the bin seat 1 and a bin coupling 73 fixed to the bin 2. The transmission member 5 is fixed to the seat coupling 72. The transmission member 5 and the seat coupling 72 can be integrally formed parts, reducing the number of parts. The input end and the output end of the seat coupling 72 are respectively connected to the driving device 71 and the bin coupling 73. The bin locking member 3 is sleeved outside the bin coupling 73 and is limited between the bin coupling 73 and the bin 2. This structure enables the cooperation of the coupling structure to be achieved simultaneously after the bin seat 1 and the bin 2 are installed.

[0036] In some embodiments of the present invention, such as Figure 1-3, as shown in FIGS. 7, a receiving cavity 11 is provided on the silo base 1, which is open downward and used for setting the silo 2. The upper part of the receiving cavity 11 is connected with a docking cavity 12 for coupling structure cooperation. The silo lock 3, the base lock 4, the transmission member 5, the elastic mechanism, and the coupling structure are located in the docking cavity 12. This structure enables the coupling structure cooperation to be achieved simultaneously after the silo base 1 and the silo 2 are installed.

[0037] In some embodiments of the present invention, as Figure 2 , 3 , as shown in FIGS. 5, 6, and 8, the silo 2 includes a container 21 and a cutter assembly provided at the bottom of the container 21. The silo 2 is used for storing materials and grinding powder at the same time. The upper part of the cutter assembly forms an input end communicating with the inside of the container 21, and the lower part of the cutter assembly forms an output end of the finished product.
