[0033] The cutting mechanism 4 includes a guide rail 43, the interior of which is slidably connected to the driving mechanism 6, the bottom end of the guide rail 43 is fixedly connected to a plurality of support rods 42, the bottom ends of the support rods 42 are fixedly connected to an arc-shaped cutting shovel 41, and the side walls of the support rods 42 are slidably connected to a fixing sleeve 44; the bottom end of the screw rod 63 is fixedly connected to a protrusion 46, the interior of the guide rail 43 is provided with a slide groove 45, the interior of the slide groove 45 is slidably connected and engages with the protrusion 46, when the cutting shovel 41 rotates back and forth into the soil, the support rod 42 drives the guide rail 43 to rotate, at this time the slide groove 45 on the side wall of the guide rail 43 moves and slides over the side wall of the protrusion 46, so that the screw rod 63 drives the guide rail 43 and the cutting shovel 41 to move up and down during the back and forth movement of the cutting shovel 41.

[0034] The side walls of the rotating drum 31, the fixed ring 32, the first tooth plate 34, and the guide rail 43 are arc-shaped, and the centers of the rotating drum 31, the fixed ring 32, the first tooth plate 34, and the guide rail 43 are located on the same straight line. In order to make the rotating drum 31, the fixed ring 32, the first tooth plate 34, and the guide rail 43 rotate coaxially, it is convenient to drive the cutting shovel 41 to rotate, and it is convenient for the screw 63 to drive the cutting shovel 41 to move up and down.

[0035] The first spring 35 is symmetrically installed inside the fixing ring 32, and the first spring 35 abuts against the side wall of the first tooth plate 34; the bottom end of the fixing ring 32 is installed with a compression mechanism 5 for contacting the ground and increasing the cutting force of the cutting shovel 41, and the compression mechanism 5 includes a chassis 51 and a second spring 54, and a plurality of second springs 54 are installed between the chassis 51 and the fixing ring 32.

When digging up the seed bamboo 1, the chassis 51 contacts the ground, so that the cylinder 2 stands on the ground. Workers only need to hold the handle 21 during use, which reduces the work intensity of workers. When some bamboo whips around the seed bamboo 1 are too thick and the cutting shovel is difficult to cut the bamboo whips, the worker steps on the chassis 51 and pulls the cylinder 2 and the cutting shovel 41 upward. The fixing ring 32 drives the second connecting rod 53 to move upward inside the first connecting rod 52, and the second spring 54 between the chassis 31 and the first connecting rod 52 is stretched, and then the cylinder 2 and the cutting shovel 41 are quickly moved downward, the second spring 54 contracts, and the screw 63 drives the cutting shovel 41 to move downward.

In order to allow the seed bamboo 1 to enter the interior of the cylinder 2 and the chassis 51 through the notch 22, it is convenient to excavate around the seed bamboo 1. At the same time, the cylinder 2 protects the seed bamboo to avoid damage to the seed bamboo during the excavation process. The rotation angle of the rotating cylinder 31 and the cutting shovel 41 is 0° to 90°. In order to facilitate the cutting shovel 41 to rotate and cut into the soil layer, it is avoided that the cutting shovel 41 rotates too much in the soil layer, causing the cutting shovel 41 to encounter too much resistance when cutting the bamboo whip, thereby reducing the probability of the cutting shovel 41 getting stuck inside the bamboo whip.

[0037] The working principle of the bamboo cultivation digging device provided by the present invention includes the following steps: the device is connected to an external power source, and when digging the seed bamboo, the cylinder 2 is moved, and the seed bamboo is allowed to enter the interior of the cylinder 2 through the notch 22, the chassis 51 is in contact with the ground, and the cylinder 2 stands on the ground. During use, the worker only needs to hold the handle 21; the side wall of the handle 21 is provided with a switch for controlling the operation of the motor 61, and when the switch is turned on, the motor 61 drives the drive shaft 64, the first gear 65 and the second gear 66 to rotate, and the second gear 66 is threadedly connected to the screw rod 63. Using the principle of spiral transmission, the second gear 66 rotates to drive the screw 63 and the cutting shovel 41 to move up and down, and the first gear The diameter of 65 is smaller than that of the second gear 66. In order to make the first gear 65 drive the second gear 66 to rotate more labor-savingly, it is convenient for the screw 63 to push the cutting shovel 41 to move into the soil to cut the bamboo whips. When the bamboo whips on one side of the bamboo 1 are cut, the switch is turned on to reverse the motor 61, so that the screw 63 moves upward and the cutting shovel 41 moves upward and separates from the soil layer; the chassis 51 is rotated, and as the position of the cutting shovel 41 is changed, all the roots around the bamboo 1 are cut off, which reduces the labor intensity of the workers and speeds up the excavation efficiency. In the excavation process, the bamboo 1 is always located inside the cylinder 2, and the cylinder 2 maintains the bamboo 1 to avoid shaking the bamboo trunk to loosen and spraining the connection between the bamboo trunk and the bamboo whip during the excavation process. When one or two bamboo whips around the seed bamboo 1 are too thick and the cutting shovel is difficult to cut the bamboo whips, the worker steps on the chassis 51 and pulls up the cylinder 2 and the cutting shovel 41, and the fixing ring 32 drives the second connecting rod 53 to move upward inside the first connecting rod 52, and the second spring 54 between the chassis 31 and the first connecting rod 52 is stretched, and then the cylinder 2 and the cutting shovel 41 are quickly moved downward, the second spring 54 contracts, and the screw 63 drives the cutting shovel 41 to move downward. Under the action of gravity, the screw 63 and the second spring, the cutting shovel 41 quickly squeezes the bamboo whip downward, thereby increasing the downward cutting force of the cutting shovel 41, quickly cutting off the bamboo whip, and improving the excavation efficiency.When the soil is relatively hard and there are too many bamboo whips around the bamboo, the cutting shovel cannot quickly dig up the bamboo, and the screw sleeve 79 is rotated. The screw sleeve 79 rotates on the side wall of the limiting rod 77 and separates from the side wall of the fixing sleeve 71. At this time, the third spring 74 inside the rotating shaft 73 loses its restraint, and the third spring 74 extends to push the prism 75, the support sleeve 78, and the limiting rod 77 to move upward. The limiting rod 77 slides inside the slot 79, and the prism 75 moves upward and contacts the drive shaft 64. As the drive shaft 64 rotates, the prism 75 is aligned with the drive shaft 64. Under the action of the third spring 74, the prism 75 enters the interior of the drive shaft 64, and the screw sleeve 79 on the side wall of the limit rod 77 is rotated. The funnel-shaped screw sleeve 79 squeezes the side wall of the fixing sleeve 71 to fix the positions of the limit rod 77, the support sleeve 78 and the prism 75. The rotation of the drive shaft 64 drives the prism 75 to rotate, and the prism 75 rotates inside the support sleeve 78 so that the prism 75 does not align with the The support sleeve 78 is disengaged; the rotation of the prism 75 drives the rotating shaft 73 and the rotating disk 36 to rotate. During the rotation of the rotating disk 36, the pull rod 37 drives the second tooth plate 38 to move back and forth inside the mounting plate 33. The second tooth plate 38 moves along the side wall of the hexagonal prism 39, and the hexagonal prism 39 causes the second tooth plate 38 to move linearly. The rotating rod 310 is rotatably connected between the rotating disk 36 and the second tooth plate 38, and the rotating rods 310 are rotatably connected to each other. When the rotating disk 36 drives the second tooth plate 38 to move When the rotary disc 36 is moved, the rotating rod 310 rotates between the rotating disc 36 and the second tooth plate 38, and the rotating rod 310 increases the stability of the movement of the second tooth plate 38; the second tooth plate 38 moves back and forth to drive the arc-shaped first tooth plate 34 to move, and the first tooth plate 34 drives the rotating drum 31 to rotate back and forth, and the rotating drum 31 drives the fixing sleeve 44, the supporting rod 42, and the cutting plate 41 to rotate back and forth, so that the cutting plate 41 quickly enters the soil to cut the bamboo whips back and forth, and quickly cuts off the bamboo whips around the bamboo plants, thereby speeding up the excavation efficiency.
