Technical Field

[0001] This invention relates to a hole-digging device, and more particularly to a hole-digging device for transplanting fruit tree seedlings. Background Technology

[0002] Before transplanting seedlings, holes need to be dug in the soil. The seedlings are then placed in the holes, and the excavated soil is used to cover the holes again. Watering and fertilization are then carried out to promote the growth and development of the seedlings. Currently, there are two main methods of digging holes: manual digging with shovels and digging with the assistance of machinery. Regardless of the method used, the excavated soil is piled around the edges of the hole. During the transplanting process, one person needs to use shovels or other tools to shovel the excavated soil back into the hole to cover the seedling's roots, while another person holds the seedling upright throughout the process to prevent the soil from bending it. Therefore, this process is quite time-consuming and labor-intensive. Summary of the Invention

[0028] To better understand the technical content of this invention, specific embodiments are provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0029] See Figures 1 to 9 This invention provides a hole-digging device for transplanting fruit tree seedlings, including a mobile vehicle with a working platform 1 on top, wheels located at the four corners of the bottom of the working platform 1, and push-pull handles at the rear of the working platform 1. The working platform 1 is moved by pushing and pulling the handles and wheels. The working platform 1 is equipped with a spiral hole-digging device, which is slidably connected to the working platform 1. A turntable 2 is rotatably connected to the bottom of the working platform 1. The working platform 1 has a drive component inside that drives the turntable 2 to rotate. A movable scraper 3 and an adjustment component are installed at the bottom of the turntable 2. One end of the movable scraper 3 is hinged to the bottom of the turntable 2, and the other end is connected to the adjustment component, which is the movable end. The center of the turntable 2 has a digging hole 4 for the spiral hole-digging device to pass through. The digging hole 4 penetrates the working platform 1. The adjustment component drives the movable scraper 3 to rotate toward the digging hole 4. The front end of the working platform 1 and the turntable 2 both have openings 5 ​​communicating with the digging hole 4, making the turntable 2 a fan-shaped ring with a circumference greater than a semicircle.

[0030] Before transplanting the seedlings, first push the mobile vehicle to the designated position, then slide the spiral digging equipment above the center of the excavation hole 4, start the spiral digging equipment to dig downwards, and the soil in the hole is brought out to the outside of the hole. After the hole is dug, turn off the spiral digging equipment and lift it back above the working platform 1, then slide it backwards away from the excavation hole 4. At this time, the hole is exposed below the excavation hole 4. Transplant the seedlings into the hole, start the drive unit to drive the turntable 2 and the movable scraper 3 to rotate, so as to... Figure 6For example, the movable scraper 3 rotates clockwise, scraping all the soil in its rotation path towards the innermost side. Under normal conditions, the movable scraper 3 is tangent to the excavation hole 4 of the turntable 2. The rotation of the movable scraper 3 scrapes all the soil into the area of ​​the excavation hole 4. By adjusting the components and the movable end, the angle between the movable scraper 3 and the excavation hole 4 can be adjusted, thereby changing the innermost position of the movable scraper 3. When the innermost position of the movable scraper 3 is inside the pit, the turntable 2 drives the movable scraper 3 to rotate, scraping the soil around the pit back into the pit. The operator only needs to straighten the seedling, greatly speeding up the soil covering time. After soil covering is completed, aligning the opening 5 of the turntable 2 with the opening 5 of the working platform 1 allows the moving vehicle to retreat from the seedling transplanting area through the opening 5 area, completing the entire transplanting work.

[0031] The movable scraper 3 is an arc-shaped plate, and the length of the movable scraper 3 is greater than the diameter of the excavation hole 4. The arc-shaped inner wall of the arc-shaped plate can better scrape the soil to the innermost side, thereby improving the soil scraping efficiency.

[0032] The turntable 2 includes a support part 6, a connecting part 7, and a working part 8. The working platform 1 has a working cavity 9 inside, and an annular slide rail 10 is provided in the working cavity 9. The bottom of the slide rail 10 has a through groove 11 that communicates with the bottom of the working platform 1. The slide rail 10 and the through groove 11 are both concentric with the excavation hole 4. The support part 6 is slidably connected to the slide rail 10. The working part 8 is located below the working platform 1. A movable scraper 3 is installed on the bottom surface of the working part 8. The connecting part 7 passes through the through groove 11 and connects the support part 6 and the working part 8 to each other. The contact surface between the connecting part 7 and the through groove 11 is a smooth surface.

[0033] The driving component includes a driving wheel 12 and a driven wheel 13 that are rotatably connected to the inner wall of the working chamber 9. A ring rack 14 is sleeved on the top outer side of the support part 6. The driving wheel 12 and the driven wheel 13 are symmetrically arranged on both sides of the support part 6. The driving wheel 12 and the driven wheel 13 are respectively meshed with the ring rack 14. The top of the working platform 1 is provided with a driving mechanism that drives the driving component to rotate.

[0034] The driving mechanism includes a drive motor 15. The output shaft of the drive motor 15 passes through the working platform 1 and is coaxially connected to the drive wheel 12. The drive wheel 12 and the driven wheel 13 are connected by a transmission chain. The upper parts of the drive wheel 12 and the driven wheel 13 are higher than the top of the support part 6, so that the transmission chain can cross the top of the support part 6 to connect the drive wheel 12 and the driven wheel 13. In order to prevent the turntable 2 from vibrating up and down due to the force of soil during operation because there is a certain space between the top of the support part 6 and the inner top of the working cavity 9, a pressing head can be provided in the inner top of the working cavity 9 to press against the top of the support part 6. The pressing head is arranged in a ring, and the contact surface between the pressing head and the support part 6 can be set as a spherical surface to reduce friction.

[0035] The drive motor 15 drives the drive wheel 12 to rotate, and the drive wheel 12 drives the driven wheel 13 to rotate synchronously through the transmission chain. Under the meshing drive of the drive wheel 12 and the driven wheel 13, the support part 6 rotates in a circle around the excavation hole 4 in the annular slide rail 10. The minimum circumferential distance between the support part 6 and the drive wheel 12 and the driven wheel 13 must be greater than the distance of the opening 5 to ensure that the drive wheel 12 and the driven wheel 13 can alternately achieve the meshing effect on the annular rack 14. Moreover, the circumferential distance of the opening 5 must be much smaller than the circumferential distance of the turntable 2 to ensure that when one end of the turntable 2 rotates to the opening 5 and disengages from the slide rail 10, most of the position of the turntable 2 is still on the slide rail 10, thereby maintaining the stability of the turntable 2 until one end of the turntable 2 re-enters the slide rail 10 on the other side.

[0036] The adjusting component includes an adjusting head 16 and a telescopic mechanism. The front end of the adjusting head 16 is provided with an adjusting column 17. The side wall of the movable end of the movable scraper 3 is provided with a horizontal groove for the sliding rod to pass through. The bottom of the horizontal groove is provided with a vertical groove that matches the adjusting column 17. The sliding rod passes through the horizontal groove. The adjusting column 17 is movably connected to the vertical groove. The telescopic mechanism is connected to the tail end of the adjusting head 16.

[0037] The telescopic mechanism includes a telescopic hydraulic cylinder 18, which is fixed to the bottom of the turntable 2, and the piston rod of the telescopic hydraulic cylinder 18 is connected to the tail end of the adjusting head 16.

[0038] When the piston rod of the telescopic hydraulic cylinder 18 extends forward, it drives the adjusting head 16 to move into the excavation hole 4. The adjusting head 16, through the adjusting column 17 and the vertical groove, drives the movable scraper 3 to rotate into the excavation hole 4, thereby adjusting the scraping range of the movable scraper 3 according to the thickness of the seedlings. At the same time, the top of the horizontal groove abuts against the top of the adjusting head 16. The adjusting head 16 and the telescopic hydraulic cylinder 18 provide a certain load-bearing function for the movable end of the movable scraper 3, and together with the hinge end, they achieve the stability of the movable scraper 3. It should be noted that the supporting equipment of the telescopic hydraulic cylinder 18 (such as oil tank, hydraulic pump, solenoid valve, and power battery) are all fixed at the bottom of the turntable 2 and rotate synchronously with the rotation of the turntable 2 to prevent phenomena such as wire entanglement and pipe entanglement.

[0039] The spiral digging device includes a mounting plate 19, a main motor 20, and a spiral drill bit 21. The main motor 20 is mounted on the top of the mounting plate 19, and the spiral drill bit 21 is located at the bottom of the mounting plate 19. The spiral drill bit 21 passes through the mounting plate 19 and is coaxially connected to the output shaft of the main motor 20. The top of the mounting plate 19 is also provided with a working handle 22, which is located on both sides of the main motor 20.

[0040] The working platform 1 is provided with sliding guide rails 23 on both sides of the excavation hole 4. A sliding plate 24 is slidably installed on the sliding guide rails 23. Guide rods 25 are provided at both the front and rear ends of the sliding plate 24. The mounting plate 19 is slidably sleeved on the guide rods 25.

[0041] The sliding plates 24 on both sides are connected to each other by reinforcing plates 26. Under the action of the sliding plates 24, the spiral digging device can slide back and forth along the direction from the center of the excavation hole 4 to the opening 5.

[0042] When in use, the spiral hole-digging equipment can be slid above the excavation hole 4 via the sliding plate 24. Under the action of gravity, the spiral hole-digging equipment passes through the excavation hole 4 and contacts the soil surface below. The main motor 20 is started to drive the spiral drill bit 21 to rotate. The working handle 22 applies a downward force to the mounting plate 19, causing the spiral drill bit 21 to dig a hole in the soil. The soil in the hole is discharged upward along the spiral blades of the spiral drill bit 21 to the perimeter of the hole. After digging the hole, the main motor 20 is turned off, and the spiral hole-digging equipment is lifted upward to the top of the working platform 1 via the working handle 22. It is then slid to the area behind the excavation hole 4 via the sliding plate 24. The spiral drill bit 21 rests against the top of the working platform 1, exposing the excavation hole 4 for seedling transplantation.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
