[0002] As an important piece of equipment for processing Chinese medicinal herbs, the herb cutting machine typically consists of a housing, a cover, a cutting chamber, a main shaft, cutting blades, and related fixing and protective devices. During operation, the main shaft drives the cutting blades to rotate at high speed via a motor. The medicinal herbs are pushed into the cutting chamber by the feeding mechanism to complete the cutting, and the cut herbs are discharged through the outlet. However, in practical applications, the cutting blades are high-frequency used components and need to be disassembled and replaced regularly to ensure cutting sharpness and processing quality. Therefore, the convenience and safety of the auxiliary structure when changing blades are particularly crucial.

[0003] In existing technologies, the disassembly and assembly of cutting machine blades generally rely on individual fixing with nuts or flanges. Disassembly often requires loosening fasteners and protective parts one by one, which is cumbersome and prone to operational risks, and cannot achieve quick blade replacement. Utility Model Content

[0007] Preferably, the protective cover is located above the mounting base, which has an L-shaped cross-section and the cover covers the short side of the mounting.

[0008] Preferably, the protective cover has multiple sets of through grooves on its surface, the through grooves are located directly above the cutting blade, and the multiple sets of through grooves correspond one-to-one with the multiple sets of cutting blades, and the cutting edge of the cutting blade and the through groove form a cutting window for the medicinal material to pass through.

[0009] Preferably, the pre-installation structure includes a pressure shell, a fixing sleeve, a connecting rod, and a locking block. The connecting rod is fixed to the lower surface of the pressure shell, and there are four sets of connecting rods arranged in a circular array around the central axis of the pressure shell. The pressure shell has a ring-shaped cross-section and is sleeved on the outside of the main shaft. The lower surface of the top rod extending from the outside of the pressure shell is in contact with the upper surface of the protective cover. The connecting rod is inserted into the interior of the mounting base. The fixing sleeve is located directly above the pressure shell and is screwed to the top of the main shaft. The bottom surface of the fixing sleeve is in contact with the top surface of the pressure shell. The locking block is engaged in a slot opened on the surface of the connecting rod. The locking block has a semi-circular cross-section, and the slot has an arc-shaped structure.

[0010] Preferably, the top of the mounting base has multiple sets of connecting slots, the locking block is fixed at the bottom of the connecting slots, the connecting slots are arranged in a circular array around the central axis of the mounting base, the connecting rod is inserted into the inside of the connecting slot, and the locking block is located on the outside of the connecting slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The auxiliary structure for a medicinal herb cutting machine proposed in this utility model allows for easy disassembly and replacement of the cutting blade. When the cutting blade needs to be disassembled and replaced, simply open the cover, unscrew the fixing sleeve with a hex wrench, and then remove the pressure shell.

[0013] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] Example 1 Please see Figures 1-8 This utility model provides a technical solution: an auxiliary structure for a medicinal herb cutting machine, including a housing 1, a cover 2 installed on the top of the housing 1 by screws, a cutting chamber 3 for cutting medicinal herbs fixed inside the housing 1, a main shaft 4 and cutting blades 9 installed inside the cutting chamber 3, multiple sets of cutting blades 9 are provided, the cutting blades 9 are installed on the mounting base 5 by screws, and the multiple sets of cutting blades 9 are arranged in a circular array around the central axis of the main shaft 4, the main shaft 4 is surrounded by the mounting base 5 and a protective cover 6, the protective cover 6 is located above the mounting base 5, the mounting base 5 is an annular structure with an "L" cross-section, the protective cover 6 covers the short side of the mounting base 5, the surface of the protective cover 6 is provided with multiple sets of through grooves, the through grooves are located directly above the cutting blades 9, and the multiple sets of through grooves correspond one-to-one with the multiple sets of cutting blades 9, and the cutting edge of the cutting blade 9 and the through groove form a cutting window for the medicinal herbs to pass through; Specifically, a medicinal herb cutting machine typically consists of a housing 1, a cover 2, a main shaft 4, a cutting blade 9, and feeding and discharging devices. The motor drives the main shaft 4 to rotate via a belt or gear. After the cutting machine starts, the medicinal herbs enter the cutting chamber 3 covered by the cover 2 through the feeding mechanism. The cutting blade 9, rotating on the main shaft 4, cuts or slices the medicinal herbs. The resulting flakes or strips of medicinal herbs are discharged through the discharge port. The protective cover 6 above the cutting blade 9 not only provides safety protection but also limits the direction of chip splashing in the cutting area. The chips are collected in the housing or through an additional chip collection structure. During the cutting process, the medicinal herbs are fed into the feeding port and then enter the cutting edge. The cut medicinal herbs are discharged along the discharge port under the action of gravity and wind force and finally enter the collection device.

[0015] Example 2 Based on Embodiment 1, in order to achieve rapid replacement of the cutting blade 9, a pre-installation structure is proposed to fix the top of the mounting base 5. The pre-installation structure includes a pressure shell 7, a fixing sleeve 8, a connecting rod 11, and a locking block 13. The connecting rod 11 is fixed to the lower surface of the pressure shell 7, and there are four sets of connecting rods 11 arranged in a circular array around the central axis of the pressure shell 7. The pressure shell 7 has a ring-shaped cross-section and is sleeved on the outside of the main shaft 4. The lower surface of the top rod extending from the outside of the pressure shell 7 fits against the upper surface of the protective cover 6. The connecting rod 11 is inserted into the mounting base 5. Inside the base 5, the fixing sleeve 8 is located directly above the pressure shell 7. The fixing sleeve 8 is screwed to the top of the main shaft 4, and the bottom surface of the fixing sleeve 8 is in contact with the top surface of the pressure shell 7. The locking block 13 is locked in the slot 12 opened on the surface of the connecting rod 11. The locking block 13 has a semi-circular cross-section, and the slot 12 has an arc-shaped structure. Multiple sets of connecting slots 10 are opened at the top of the mounting base 5. The locking block 13 is fixed at the bottom of the connecting slot 10. The connecting slots 10 are arranged in a circular array around the central axis of the mounting base 5. The connecting rod 11 is inserted into the inside of the connecting slot 10, and the locking block 13 is located on the outside of the connecting slot 10. Specifically, during the use of the herb cutting machine, when the cutting blade 9 needs to be replaced, the operator first loosens the fixing sleeve 8 at the top of the main shaft 4. The fixing sleeve 8 is tightly fitted with the pressure shell 7. After loosening, the constraint on the pressure shell 7 is released. At this time, the pressure shell 7, along with the connecting rod 11 and the protective cover 6, will be removed together under the overall movement, avoiding the tedious steps of disassembling each part individually. As the pressure shell 7 and the mounting base 5 move out synchronously, when the connecting rod 11 is pulled out of the connecting groove 10, the locking block 13 is engaged in the groove on the surface of the connecting rod 11, according to... Figure 6 As can be seen, since the engagement is shallow, it can be easily pulled out. Due to the mutual contact, when the pressure shell 7 is pulled out, the protective cover 6 can be smoothly detached, and the tool installation area is fully exposed, so the operator can directly replace the cutting blade 9.

[0016] To reiterate, the direction of the screw connection of the fixing sleeve 8 is opposite to the direction of rotation of the spindle 4, so that the cutting blade 9 becomes tighter as it rotates, preventing it from falling off and improving safety.

[0017] When using the cutting blade 9, the operator first loosens the fixing sleeve 8 at the top of the spindle 4. The fixing sleeve 8 fits tightly with the pressure shell 7. Loosening it releases the constraint on the pressure shell 7. Then, the pressure shell 7, under the overall action, pulls the connecting rod 11 and the protective cover 6 out together, avoiding the tedious operation of disassembling each part individually. At the same time, the mounting base 5 also moves out, and under the limiting cooperation of the slot 12 and the locking block 13, a reliable separation is achieved, allowing the protective cover 6 to detach smoothly and the tool installation area to be fully exposed. At this time, the cutting blade 9 can be directly disassembled and replaced. Through the linkage of the pressure shell 7, the mounting base 5, and the protective cover 6, the replacement efficiency is significantly improved, the safety risks during operation are effectively reduced, and the convenience and stability of tool 9 replacement are guaranteed.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
