[0002] Gastrodia elata is a common Chinese medicinal herb. When planting it, it is necessary to dig a pit, lay mushroom bags and wood in the pit, and then plant the Gastrodia elata rhizomes.

[0003] The prior art discloses an adjustable hole-digging device for planting Gastrodia elata (publication number: CN210183849U), which includes a first sleeve, a second sleeve slidably connected to the inner wall of the first sleeve, a drive motor fixedly connected to the inner wall of the second sleeve, a hole-digging mechanism fixedly connected to the output end of the drive motor through a coupling, a first outer shell fixedly connected to both the left and right sides of the first sleeve, an electromagnet fixedly connected to the bottom of the inner wall of the first outer shell, and a reset mechanism fixedly connected to both the left and right sides of the second sleeve.

[0004] In the existing technology, the rotary drilling machine is installed on a support frame, and the bottom of the support frame has rollers. When the rotary drilling machine is pressed down, the entire support frame will shift due to the rollers, causing the user to be bumped or hit. Therefore, the entire device is unstable when digging holes by relying entirely on rollers, and there is room for optimization.

[0005] Therefore, we propose an adjustable structure and its pit-digging cultivation device. Utility Model Content

[0006] The present invention mainly solves the technical problem that the above-mentioned device will deviate when digging a hole, and provides an adjustment structure and a hole-digging cultivation device thereof.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable structure and its pit-digging cultivation device, comprising:

[0008] The bracket forms a frame, and a support rod is fixedly installed at the bottom of the bracket;

[0009] A switching assembly is set at the bottom of the support rod to support the bracket. The switching assembly includes rollers, rotating plates and wheels. The support rods are in pairs. The bottom of the two support rods in the same group are rotatably fixed with rollers. The other group of two support rods has a rotating plate that can be rotatably adjusted on one side. Each rotating plate is rotatably connected to a wheel on one side.

[0010] The lifting assembly is located on top of the bracket for installation.

[0011] In a preferred embodiment of this utility model, the switching assembly further includes a rotating shaft and a thrust threaded hole. The rotating shaft is fixedly connected to the rotating plate and rotatably connected to the support rod. Two thrust threaded holes are opened on one side of the rotating plate. Bolts are threaded into the thrust threaded holes. A positioning hole is opened on the side wall of the support, and the bolt can enter the positioning hole.

[0012] In a preferred embodiment of this utility model, the rotating shaft is fixedly installed at an eccentric position on the rotating plate, and a shaft hole is provided on one side of the support. The rotating shaft is rotatably disposed in the shaft hole. The side wall of the support rod is provided with a number of positioning holes arranged in a circular array with the shaft hole as the center, and bolts can be inserted into different positioning holes.

[0013] In a preferred embodiment of this utility model, the lifting assembly includes a tray, a limiting rod, a first adjusting nut, and a second adjusting nut. Several limiting rods are fixed to the top of the bracket. The tray is slidably connected to the limiting rods. The limiting rods are threadedly connected to the first adjusting nut and the second adjusting nut. The first adjusting nut and the second adjusting nut are located below and above the tray, respectively. A spring is provided between the first adjusting nut and the tray.

[0014] In a preferred embodiment of this utility model, holes are provided at the four corners of the tray, the limiting rod passes through the corresponding holes, a gasket is provided on the top of the tray, and the spring is sleeved on the tray and located between the first adjusting nut and the gasket.

[0015] In a preferred embodiment of this invention, the lifting assembly further includes an adjusting screw, which is threadedly connected to the bracket, allowing the tray to slide along the limiting rod and abut against the end of the adjusting screw.

[0016] A trenching cultivation device includes a rotary drilling rig body, with a drill rod fixedly mounted on the output shaft of the rotary drilling rig body. The rotary drilling rig body is installed and fixed by the aforementioned adjustment structure, and the rotary drilling rig body is fixedly mounted on the top of a tray.

[0017] Beneficial effects

[0018] This utility model provides an adjustable structure and its hole-digging cultivation device. It has the following beneficial effects:

[0019] 1. This adjustable structure and its pit-digging cultivation device, by installing rollers at the bottom of two of the support rods, allows the entire support frame to tilt towards the rollers, causing the other two support rods to lift off the ground. By tilting and dragging the entire device on the ground, the position of the pit can be adjusted. Simultaneously, the rotating plate can be rotated, rotating around the axis of rotation at a certain angle, so that the wheels contact the ground. By tightening the bolts and thrust threaded holes, the thrust threaded holes are inserted into the corresponding positioning holes, thereby locking the rotating plate. Thus, the wheels and rollers can simultaneously contact the ground, and the entire support frame tilts towards the rollers, allowing the entire device to be dragged in an tilted state to dig trenches on the ground. When the rotating plate is rotated so that the wheels lift off the ground, the support rod where the rotating plate is located can contact the ground, thereby achieving vertical pit digging. It has a more flexible usage mode and facilitates flexible switching between trenching and pit digging.

[0020] 2. This adjustable structure and its pit-digging cultivation device, by mounting the rotary drilling rig body on a tray, can press down the tray to make the rotary drilling rig body contact the ground and dig a pit. Rotating the first adjusting nut can compress the spring to adjust the spring's preload value, thereby adjusting the resistance of the tray sliding along the limit rod. Rotating the second adjusting nut can press down the tray so that the tray is completely fixed by the second adjusting nut and the first adjusting nut. When the support is tilted and moving, it is convenient to fix the depth of the trench. Rotating the adjusting screw, when the tray touches the adjusting screw, the tray cannot continue to descend, and the depth of the pit is fixed, ensuring that the pit depth dug in continuous operation is consistent.

[0021] 3. This adjustable structure and its hole-digging cultivation device are fixed on a tray by the rotary drilling rig body. By switching the state of the support, the rotary drilling rig can dig holes vertically or dig trenches on the ground as the support moves. The depth of both trenching and hole digging can be adjusted and fixed, which has a more flexible way of use and reduces the labor intensity of moving the entire device to dig holes.

[0028] An adjustable structure and its hole-digging cultivation device, such as Figure 1 As shown, it includes:

[0029] The bracket 10 forms a frame, and a support rod is fixedly installed at the bottom of the bracket 10;

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the switching assembly is located at the bottom of the support rod to support the bracket 10. The switching assembly includes rollers 11, rotating plates 12, and wheels 13. The support rods are arranged in pairs. The bottom of the two support rods in the same pair are rotatably and fixedly mounted with rollers 11. The other pair of two support rods are rotatably mounted on one side with a rotating plate 12 that can be adjusted in position. Each rotating plate 12 is rotatably connected to a wheel 13 on one side. The switching assembly also includes a rotating shaft 14 and thrust threaded holes 15. The rotating shaft 14 is fixedly connected to the rotating plate 12 and rotatably connected to the support rod. Two thrust threaded holes 15 are opened on one side of the rotating plate 12. Bolts are internally threaded into the thrust threaded holes 15. The side wall of the support is provided with positioning holes, and the bolts can enter the positioning holes. The rotating shaft 14 is fixedly installed at an eccentric position on the rotating plate 12. A shaft hole is opened on one side of the support, and the rotating shaft 14 is rotatably positioned in the shaft hole. The side wall of the support rod is provided with a number of positioning holes arranged in a circular array with the shaft hole as the center. Bolts can be inserted into different positioning holes.

[0031] In this design, by installing rollers 11 at the bottom of two of the support rods, the entire support 10 can be tilted towards the rollers 11, causing the other two support rods to lift off the ground. By tilting and dragging the entire device on the ground, the position of the pit can be adjusted. At the same time, the rotating plate 12 can also be rotated. The rotating plate 12 rotates around the rotating shaft 14 at a certain angle, so that the wheel 13 contacts the ground. The bolt is tightened into the thrust thread hole 15, so that the thrust thread hole 15 is inserted into the corresponding positioning hole, thereby locking the rotating plate 12. Then, the wheel 13 and the roller 11 can contact the ground simultaneously. The entire support 10 is tilted towards the roller 11, and the entire device can be dragged in an tilted state to dig trenches on the ground. When the rotating plate 12 is rotated so that the wheel 13 lifts off the ground, the support rod on which the rotating plate 12 is located can contact the ground, thereby realizing vertical pit digging. It has a more flexible usage mode and is convenient to switch flexibly between trenching and pit digging.

[0032] like Figure 1 and Figure 5As shown, the lifting assembly is mounted on top of the bracket 10.

[0033] The lifting assembly includes a tray 20, a limiting rod 21, a first adjusting nut 22, and a second adjusting nut 23. Several limiting rods 21 are fixed to the top of the bracket 10. The tray 20 is slidably connected to the limiting rods 21. The limiting rods 21 are threadedly connected to the first adjusting nut 22 and the second adjusting nut 23. The first adjusting nut 22 and the second adjusting nut 23 are located below and above the tray 20, respectively. A spring is provided between the first adjusting nut 22 and the tray 20. Holes are provided at the four corners of the tray 20. The limiting rods 21 pass through the corresponding holes. A washer is provided on the top of the tray 20. The spring is sleeved on the tray 20 and located between the first adjusting nut 22 and the washer. The lifting assembly also includes an adjusting screw 24. The adjusting screw 24 is threadedly connected to the bracket 10. The tray 20 can slide along the limiting rod 21 and abut against the end of the adjusting screw 24.

[0034] In this solution, by mounting the rotary drilling rig body on the pallet 20, the pallet 20 can be pressed down to allow the rotary drilling rig body to contact the ground and dig a pit. Rotating the first adjusting nut 22 can compress the spring and adjust the spring's preload value, thereby adjusting the resistance of the pallet 20 sliding along the limit rod 21. Rotating the second adjusting nut 23 can press the pallet 20 down so that the pallet 20 is completely fixed by the second adjusting nut 23 and the first adjusting nut 22. This facilitates fixing the trench depth when the support 10 is tilted and moving. Rotating the adjusting screw 24 will prevent the pallet 20 from descending further when it comes into contact with the adjusting screw 24, thus fixing the trench depth and ensuring that the trench depth dug in continuous operation is consistent.

[0035] As shown in the figure, a trenching cultivation device includes a rotary drilling rig body. The output shaft of the rotary drilling rig body is fixedly equipped with a drill rod. The rotary drilling rig body is installed and fixed by the aforementioned adjustment structure. The rotary drilling rig body is fixedly mounted on the top of the tray 20. The rotary drilling rig body needs to be connected to a power source for use. By fixing the rotary drilling rig body on the tray 20 and switching the state of the support 10, the rotary drilling rig can dig trenches vertically or move with the support 10 to open trenches on the ground. The depth of both trenching and digging can be adjusted and fixed, providing a more flexible way of use.

[0036] The working principle of this utility model is as follows: The rotary drilling rig body is mounted on the tray 20. Pressing down the tray 20 allows the rotary drilling rig body to contact the ground and dig a hole. Rotating the first adjusting nut 22 compresses the spring, adjusting its preload value. This adjusts the resistance of the tray 20 sliding along the limiting rod 21. Rotating the second adjusting nut 23 presses the tray 20 down, completely fixing it in place by the second adjusting nut 23 and the first adjusting nut 22. This facilitates fixing the trench depth when the support 10 is tilted and moving. The support 10 can be tilted towards the roller 11. The device is tilted so that the other two support rods are off the ground. The tilted device can be dragged across the ground to adjust the position of the pit. At the same time, the rotating plate 12 can be rotated. The rotating plate 12 rotates around the rotating shaft 14 at a certain angle so that the wheel 13 contacts the ground. The bolt is tightened into the thrust thread hole 15 so that the thrust thread hole 15 is inserted into the corresponding positioning hole, thereby locking the rotating plate 12. Then the wheel 13 and the roller 11 can contact the ground at the same time. The bracket 10 is tilted towards the roller 11, and the entire device can be dragged in a tilted state to dig trenches on the ground.
