[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a He Shou Wu (Polygonum multiflorum) digging device that can protect the rhizome, comprising;

[0025] Expanding drilling assembly 1 includes a support plate 11, an outer ring turntable 12 is rotatably connected to the outer side of the support plate 11, an operating handle 13 is fixedly connected to the top outer side of the outer ring turntable 12, an extension frame 14 is fixedly connected to the bottom end of the outer ring turntable 12, and a toothed ring 15 is fixedly connected to the bottom end of the extension frame 14.

[0026] The expansion drilling assembly 1 is the core part of the radix polygoni multifidi digging device, mainly used for drilling into the soil and expanding the digging area, so as to separate the rhizome of radix polygoni multifidi from the soil, while protecting the rhizome from being damaged. The support disc 11 is the basic structure of the entire expansion drilling assembly 1, which plays a supporting and fixing role. It is connected with the outer ring rotating disc 12, which ensures the stable rotation of the outer ring rotating disc 12. The outer ring rotating disc 12 is the main rotating part of the expansion drilling assembly 1, which realizes the functions of drilling and expansion through rotation. When the outer ring rotating disc 12 rotates, it drives the extension frame 14 and the toothed ring 15 at the bottom to rotate together, thereby realizing the effect of drilling and expansion. The operation handle 13 is the handle for the operator to control the rotation of the outer ring rotating disc 12, which realizes the control of the digging device through manual operation. The operation handle 13 transmits the force of the operator to the outer ring rotating disc 12 through its connection with the outer ring rotating disc 12, so that it rotates. The extension frame 14 is a structure connecting the outer ring rotating disc 12 and the toothed ring 15, which plays a supporting and force transmitting role. The extension frame 14 transmits the rotating force of the outer ring rotating disc 12 to the toothed ring 15 through its structural design, which ensures that the toothed ring 15 can stably drill into the soil and expand the digging area. The toothed ring 15 is the part directly contacting with the soil, which realizes the functions of drilling and expansion through its tooth structure. When the toothed ring 15 rotates, its tooth structure can effectively drill into the soil, and through the shape and arrangement of the teeth, the soil is expanded outward, thereby forming a larger digging area. The drilling process: the operator controls the rotation of the outer ring rotating disc 12 through the operation handle 13, and the outer ring rotating disc 12 drives the extension frame 14 and the toothed ring 15 to rotate together. The tooth structure of the toothed ring 15 drills into the soil, and through its rotation and the shape of the teeth, the soil is expanded outward, forming a larger digging area. During the drilling process, the design of the toothed ring 15 ensures the protection of the radix polygoni multifidi rhizome. The shape and arrangement of the teeth can avoid direct damage to the rhizome, while expanding the soil outward, so that the rhizome is gradually exposed. The operator can control the rotation speed and direction of the operation handle 13 to further ensure the accuracy of the digging process and the protection of the rhizome;

[0027] As shown in Figure 1 , Figure 3 and Figure 4 , the grabbing assembly 2 includes positioning columns 21 for providing positioning, the positioning columns 21 are arranged in a circular array and fixedly connected to the bottom end of the support disc 11, the inside of the positioning column 21 is fixedly connected with a positioning block 22, the bottom end of the positioning block 22 is rotatably connected with a grabbing claw 23, the diameter of the extension frame 14 is larger than that of the grabbing claw 23 and is outwardly expanded, the top end of the grabbing claw 23 away from the positioning block 22 is rotatably connected with a movable adjusting block 24, the outer side of the movable adjusting block 24 is rotatably connected with an extension operating rod 25, the top end of the extension operating rod 25 is fixedly connected with a telescopic handle 26, and the outer side of the extension operating rod 25 is slidably connected in the inside of the support disc 11;

[0028] The positioning column 21 is used to provide positioning function, and the positioning column 21 can evenly distribute the grabbing force during the excavation process through the circular array layout, so as to avoid local excessive pressure on the root of the radix polygoni multifidi, thereby protecting the root from being damaged. The positioning block 22 is fixedly connected to the inside of the positioning column 21, and plays a further positioning and supporting role, so as to ensure that the grabbing claw 23 can accurately aim at the root position of the radix polygoni multifidi and provide necessary supporting force, so that the grabbing claw 23 can stably grab the root. The grabbing claw 23 is directly in contact with the root of the radix polygoni multifidi, and is used to grab and fix the root. The movable adjusting block 24 is used to adjust the grabbing force and angle of the grabbing claw 23, so as to ensure the flexibility of the grabbing process. The extension operating rod 25 is used to transmit the control force of the operator, so that the grabbing claw 23 can flexibly adjust the position and angle. The telescopic handle 26 is a handle for the operator to control the extension operating rod 25, and the control of the grabbing assembly 2 is realized through manual operation. The operator controls the extension and rotation of the extension operating rod 25 by operating the telescopic handle 26, so as to adjust the position and angle of the grabbing claw 23. The grabbing claw 23 can flexibly grab the root of the radix polygoni multifidi through the adjustment of the movable adjusting block 24. The design of the grabbing claw 23 considers the shape and size of the root, so that the root can be effectively grabbed and fixed, and damage to the root during the grabbing process is avoided. The design of the grabbing claw 23 ensures the protection of the root of the radix polygoni multifidi during the grabbing process. The shape and arrangement of the grabbing claw 23 can avoid direct damage to the root, and the adjustment of the movable adjusting block 24 ensures that the grabbing force is moderate and will not cause excessive pressure on the root. The operator can further ensure the accuracy of the grabbing process and the protection of the root by controlling the extension and rotation of the telescopic handle 26. When the grabbing claw 23 successfully grabs the root of the radix polygoni multifidi, the operator can take the root out of the soil through the control of the extension operating rod 25 and the telescopic handle 26.

[0029] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments shall fall within the protection scope of the present application.
