Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 , Figure 3The utility model provides an embodiment: a feeding mechanism for a medicinal material harvester, comprising a feeding hopper 1 and a connecting frame 2, the front and rear sides of the outside of the feeding hopper 1 are fixedly connected with a connecting plate 4, the top of the connecting plate 4 is fixedly connected with a motor 5, the output end of the motor 5 is fixedly connected with a protrusion 6, the front and rear sides of the outside of the feeding hopper 1 are fixedly connected with a fixing plate 3, the outside of the fixing plate 3 is fixedly connected with a fixing ring 22, the inside of the fixing ring 22 is slidably connected with a moving column 7, the outside of the moving column 7 is provided with a spring 8, the outside of the connecting frame 2 is fixedly connected with a mounting shell 12, the inside of the mounting shell 12 is fixedly connected with a fixed connection sliding Column 23, the internal sliding connection of the sliding column 23 is connected with a connecting block 13, the front and rear sides of the outside of the feed hopper 1 are fixedly connected with mounting plates 9, a rotating groove 10 is provided inside the mounting plate 9, the external sides of the connecting frame 2 are fixedly connected with rotating columns 11, and an excavation assembly is installed at the bottom of the connecting frame 2, the outside of the protrusion 6 is in contact with one end of the moving column 7, one end of the moving column 7 is rotatably connected to the outside of the connecting block 13, the outside of the connecting block 13 is slidably connected to the inner wall of the mounting shell 12, the outside of the rotating column 11 is rotatably connected to the inner wall of the rotating groove 10, and one end of the spring 8 is fixedly connected to one side of one of the fixed rings 22.

[0031] Specifically, the feed hopper 1 is one of the core components of the medicinal material harvester. The feed hopper 1 is responsible for shoveling the medicinal materials in the soil and sending them to the subsequent processing equipment. The design of the feed hopper 1 takes into account the efficiency and depth of medicinal material excavation to ensure the effective collection of medicinal materials. The connecting plate 4 is fixedly connected to the front and rear sides of the outside of the feed hopper 1 to support and fix the motor 5. The motor 5 is used as a driving source, and its output end is fixedly connected to the protrusion 6, and the movement of the entire feeding mechanism is driven by rotating the protrusion 6. The moving column 7 slides inside the fixed ring 22 and contacts the protrusion 6. When the motor 5 drives the protrusion 6 to rotate, the protrusion 6 will push the moving column 7 to reciprocate in the fixed ring 22. A spring 8 is arranged on the outside of the moving column 7 to provide a reset force when the moving column 7 moves to ensure the continuity and stability of the movement. The connecting block 13 slides inside the sliding column 23, one end of which is rotatably connected to the moving column 7, and the other end is slidably connected to the inner wall of the mounting shell 12. In this way, when the moving column 7 reciprocates, the connecting block 13 will slide along the sliding column 23 and drive the connecting frame 2 to move accordingly.

[0032] Reference Figure 1 , Figure 2 , Figure 3The excavation assembly includes a reinforcing plate 14, one side of the top of the reinforcing plate 14 is fixedly connected to the bottom of the connecting frame 2, a plurality of bucket tooth grooves 19 are provided on one side of the top of the reinforcing plate 14, a large bucket tooth 15 is slidably connected to the inner wall of the plurality of bucket tooth grooves 19, the internal thread of the large bucket tooth 15 is connected to a bolt 16, a bucket tooth groove 20 is provided on the outside of the large bucket tooth 15, a small bucket tooth 21 is slidably connected to the inner wall of the bucket tooth groove 20, and the internal thread of the small bucket tooth 21 is connected to two bolts 17.

[0033] Specifically, the large bucket teeth 15 and the small bucket teeth 21 are used together so that the excavation assembly can efficiently excavate the soil and grab the medicinal materials. The small bucket teeth 21 cut into the soil first, sharing the excavation force with the large bucket teeth 15, and also breaking the soil, making it easier to dig out the medicinal materials. The large bucket teeth 15 and the small bucket teeth 21 are fixed to the bucket tooth groove by threaded connection, so they can be easily disassembled and replaced. This design not only reduces maintenance costs, but also improves the continuous working ability of the excavation assembly. The reinforcing plate 14 is the main supporting component of the excavation assembly, and its sturdy structure can withstand various impacts and frictions during the excavation process. At the same time, the design of the bucket tooth groove also ensures the stable installation and reliable operation of the bucket teeth. By adjusting the number and installation angle of the large bucket teeth 15 and the small bucket teeth 21, the excavation assembly can adapt to the excavation needs of different soil textures and medicinal material distribution conditions. This flexibility makes the excavation assembly have a wide range of application prospects in medicinal material harvesters.

[0034] Reference Figure 1 , Figure 2 , Figure 3 The large bucket tooth 15 is threadedly connected to the top side of the reinforcing plate 14 through a bolt 16, the small bucket tooth 21 is threadedly connected to the top side of the large bucket tooth 15 through a bolt 2 17, and the bottom of the reinforcing plate 14 is threadedly connected to a reinforcing block 18 through a bolt 16.

[0035] Specifically, the large bucket teeth 15 are threadedly connected to the bucket tooth groove 19 by bolts 16. This detachable connection method facilitates the replacement and maintenance of the bucket teeth. The outside of the large bucket teeth 15 is also provided with bucket tooth grooves 20 for installing small bucket teeth 21. The small bucket teeth 21 are threadedly connected to the bucket tooth grooves 20 by two bolts 17, which also realizes a detachable design. The small bucket teeth 21 can contact the excavation area first, share the force of the large bucket teeth 15, and reduce the wear and deformation of the large bucket teeth 15. The reinforcement block 18 is fixed to the bottom of the reinforcement plate 14 by bolts 16, further enhancing the structural strength of the entire reinforcement assembly.

[0036] Working principle: When the feed hopper 1 needs to harvest the medicinal materials in the soil layer, first start the motor 5 to move the driving protrusion 6, and then drive the moving column 7 to move back and forth along the inner wall of the fixed ring 22, and then drive the rotating column 11 on the connecting frame 2 to move back and forth along the rotating groove 10, so as to drive the excavation assembly on the connecting frame 2 to shovel the soil layer evenly, so as to avoid the shoveled soil layer being a whole, affecting the subsequent groundbreaking work.

[0037] When the bucket teeth are found to be damaged and cannot be used, there is no need to disassemble the entire excavation assembly, only one of the bucket teeth needs to be replaced. When the large bucket teeth 15 cannot be used, the bolt 16 is removed from the large bucket teeth 15 and the reinforcing plate 14 by a tool, so that the large bucket teeth 15 are separated from the bucket tooth groove 19, thereby realizing the disassembly of the large bucket teeth 15, and then replacing the new large bucket teeth 15. During installation, it is only necessary to install the large bucket teeth 15 in the bucket tooth groove 19 by a tool with the bolt 16. When the small bucket teeth 21 cannot be used, the two bolts 2 17 are removed from the small bucket teeth 21 and the large bucket teeth 15 by a tool, so that the small bucket teeth 21 are separated from the bucket tooth groove 20, thereby realizing the disassembly of the small bucket teeth 21, and then replacing the new small bucket teeth 21. During installation, it is only necessary to install the two bolts 2 17 in the bucket tooth groove 20 by a tool. When the feed hopper 1 is harvesting medicinal materials, the small bucket teeth 21 first contact the contact surface of the excavation area. The small bucket teeth 21 have a small contact surface and are easy to shovel into the soil, sharing the contact surface with the large bucket teeth 15, making it convenient for the large bucket teeth 15 to shovel into the soil, minimizing the occurrence of severe wear or deformation of the large bucket teeth 15 due to friction, and also avoiding the need to dismantle, maintain or replace the large bucket teeth 15, thereby effectively improving the durability of the feed hopper 1.
