AI Technical Summary
The blade depth of existing tea garden weeding devices cannot be precisely adjusted, resulting in poor weeding effect and an inability to adapt to differences in weed root depth, tea tree growth stage, and soil conditions.
A blade depth adjustment buckle was designed. Through the cooperation structure of the adjustment buckle, adjustment disc and insertion shaft, the cutting blade depth can be adjusted in stages by mechanical movement to adapt to the different root depths of weeds, the growth stage of tea trees and the changes in soil hardness.
It achieves a match between blade depth and weeding needs, improving the targeting and efficiency of weeding operations, simplifying the operation process, and reducing labor costs.

Abstract
Claims
1. A blade depth adjustment clip for a tea plantation weeding device comprising a frame (100) characterised in that: The front end of the frame (100) is equipped with a weeding mechanism (200) for weeding. The weeding mechanism (200) includes a main shaft (210) rotatably connected to the front end of the frame (100), a sleeve (220) sleeved on the outside of the main shaft (210) and coaxial with the main shaft (210), a plurality of cutting blades (230) arranged in a circular array on the outside of the sleeve (220) with the axis of the main shaft (210) as the center, a pair of end plates (240) connecting the main shaft (210) and the sleeve (220), and a plurality of adjusting buckles (250) for fixing the sleeve (220) and the end plates (240). The main shaft (210) is coaxial with the sleeve. A plurality of adjusting discs (211) are fixedly connected. An annular groove (2111) is formed on the outer peripheral surface of the adjusting disc (2111). A plurality of adjusting grooves (2112) are symmetrically formed on the inner walls of the left and right sides of the annular groove (2111). A plurality of connecting rods (231) are fixed on the bottom surface of the cutting blade (230). The bottom end of the connecting rod (231) passes through the sleeve (220) and extends into the annular groove (2111). The connecting rod (231) is slidably connected to the sleeve (220). A plug shaft (232) passes through the bottom end of the connecting rod (231) laterally. The first and last ends of the plug shaft (232) extend into two symmetrical adjusting grooves (2112) respectively.
2. A blade depth adjustment clip for a tea garden weeding device according to claim 1, characterised in that: A rotary motor (110) is installed on the left end face of the front end of the frame (100), and the end of the output shaft of the rotary motor (110) is coaxially and fixedly connected to the main shaft (210).
3. The blade depth adjustment clip for a tea garden weeding device of claim 1, wherein: The adjustment groove (2112) is an inclined groove structure on the adjustment disk (211). The outer end of the adjustment groove (2112) is connected to the outer end face of the adjustment disk (211). A plurality of adjustment grooves (2112) are arranged in a ring array on the adjustment disk (211) with the axis of the main shaft (210) as the center. The number of adjustment grooves (2112) is equal to the number of cutting blades (230).
4. The blade depth adjustment clip for a tea garden weeding device of claim 1, wherein: The sleeve (220) has a hollow cylindrical structure that is open on both sides. Several guide sleeves (221) are fixed on the outer circumferential surface of the sleeve (220). The number of guide sleeves (221) is equal to the number of connecting rods (231) and their positions correspond one-to-one. The connecting rods (231) pass through the guide sleeves (221) and are slidably connected to the guide sleeves (221).
5. The blade depth adjustment clip for a tea garden weeding device of claim 1, wherein: Connecting discs (212) are fixed on the outer circumferential surfaces of both ends of the main shaft (210). The end discs (240) are sleeved on the outside of the main shaft (210) and coaxially fixed on the connecting discs (212) by bolts.
6. The blade depth adjustment buckle of the tea garden weeding device according to claim 1, characterized in that: The outer peripheral edge of the outer end face of the end plate (240) is convex outward. The two end plates (240) respectively close the beginning and end ends of the sleeve (220). The adjusting buckle (250) is installed at the outer peripheral edge of the end plate (240) and the end edge of the sleeve (220).
7. The blade depth adjustment buckle of the tea garden weeding device according to claim 1, characterized in that: The outer peripheral edge of the end plate (240) and the end edge of the sleeve (220) are provided with several through holes arranged in a circular array around the axis of the main shaft (210). The adjusting buckle (250) is U-shaped and is threaded with a shank bolt (251). The threaded end of the shank bolt (251) passes through the top of the adjusting buckle (250), the edge of the end through hole of the sleeve (220), and the outer peripheral edge through hole of the end plate (240) and is then threaded to the bottom of the adjusting buckle (250).
8. The blade depth adjustment clip for a tea garden weeding device of claim 1, wherein: By rotating the sleeve (220) to change the relative angle between the adjusting plate (211) and the sleeve (220), the insert shaft (232) can push the connecting rod (231) to extend outward or retract inward under the action of the adjusting groove (2112).
