DETAILED DESCRIPTION

[0028] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0029] See also Figures 1 to 9 The present invention provides a pit digging device for transplanting fruit tree seedlings, comprising a mobile vehicle with a working platform 1 on the top, wheels arranged at the four corners of the bottom of the working platform 1, a push-pull handrail arranged at the rear of the working platform 1, and the working platform 1 is pushed to move by the push-pull handrail and the wheels, the working platform 1 is provided with a spiral pit digging device, the spiral pit digging device is slidably connected to the working platform 1, a turntable 2 is rotatably connected to the bottom of the working platform 1, a driving component for driving the turntable 2 to rotate is arranged inside the working platform 1, a movable scraper 3 and an adjusting 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, which is a hinged end, and the other end is connected to the adjusting component, which is a movable end, an excavation hole 4 for the spiral pit digging device to pass through is arranged at the center of the turntable 2, the excavation hole 4 runs through the working platform 1, and the adjusting component drives the movable scraper 3 to flip toward the excavation hole 4, the front end of the working platform 1 and the turntable 2 are both provided with an opening 5 communicating with the excavation hole 4, so that the turntable 2 is in the shape of a fan 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 pit digging device to the top of the center of the excavation hole 4, start the spiral pit digging device to dig the pit downward, and the soil in the pit is brought out to the periphery of the pit. After the pit excavation is completed, shut down the spiral pit digging device and lift it back to the top of the working platform 1, then slide it backward to leave the excavation hole 4. At this time, the pit is exposed under the excavation hole 4, transplant the seedlings into the pit, start the driving component to drive the turntable 2 and the movable scraper 3 to rotate, so as to Figure 6For example, the movable scraper 3 rotates clockwise, and the movable scraper 3 scrapes all the soil in the rotation path to the innermost side. Under normal conditions, the movable scraper 3 is tangent to the excavation hole 4 of the turntable 2. The movable scraper 3 rotates to scrape all the soil into the excavation hole 4 area. The angle between the movable scraper 3 and the excavation hole 4 can be adjusted by adjusting the cooperation of the adjustment component and the movable end, thereby changing the innermost position of the movable scraper 3. When the innermost position of the movable scraper 3 is in the pit, the turntable 2 drives the movable scraper 3 to rotate to scrape the soil around the pit back into the pit. The operator only needs to straighten the seedlings, which greatly speeds up the soil covering time. After the soil covering is completed, the opening 5 of the turntable 2 is aligned with the opening 5 of the working platform 1, and the mobile vehicle can move backward to leave the transplanting area of ​​the seedlings from the opening 5 area to complete the entire transplanting work.

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

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

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

[0034] The driving mechanism includes a driving motor 15, the output shaft of which passes through the working platform 1 and is coaxially connected to the driving wheel 12, and the driving wheel 12 is connected to the driven wheel 13 through a transmission chain. The upper parts of the driving wheel 12 and the driven wheel 13 should be 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 driving wheel 12 and the driven wheel 13. In order to prevent the turntable 2 from vibrating up and down due to the force of the soil during the working process due to the presence of a certain space between the top of the support part 6 and the inner top of the working chamber 9, a pressing head for resisting the top of the support part 6 can be set at the inner top of the working chamber 9. The pressing heads are arranged in a ring, and the contact surface between the pressing heads and the support part 6 can be set to a spherical surface to reduce friction.

[0035] The driving motor 15 drives the active wheel 12 to rotate, and the active wheel 12 drives the driven wheel 13 to rotate synchronously through the transmission chain. Under the meshing drive of the active wheel 12 and the driven wheel 13, the support part 6 rotates in a circle in the annular slide rail 10 with the excavated hole 4 as the center. The minimum circumferential distance between the active wheel 12 and the driven wheel 13 of the support part 6 is greater than the distance of the opening 5, ensuring that the active wheel 12 and the driven wheel 13 can alternately achieve the meshing effect on the annular rack 14, and the circumferential distance of the opening 5 is much smaller than the circumferential distance of the turntable 2, ensuring 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. An adjusting column 17 is vertically arranged at the front end of the adjusting head 16. A transverse groove for a sliding rod to pass through is provided on the side wall of the movable end of the movable scraper 3. A vertical groove matching the adjusting column 17 is provided at the bottom of the transverse groove. The sliding rod passes through the transverse 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 a 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, and the adjusting head 16 drives the movable scraper 3 to flip into the excavation hole 4 through the adjusting column 17 and the vertical groove, so as to adjust 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, and the adjusting head 16 and the telescopic hydraulic cylinder 18 play a certain load-bearing role on the movable end of the movable scraper 3, and cooperate with the hinged end to achieve the stability of the movable scraper 3. It should be noted that the supporting equipment of the telescopic hydraulic cylinder 18 (such as the oil tank, hydraulic pump, solenoid valve and power battery, etc.) are all fixed at the bottom of the turntable 2, and rotate synchronously with the rotation of the turntable 2 to prevent the occurrence of wire winding and pipe winding.

[0039] The spiral digging equipment includes a mounting plate 19, a main motor 20 and a spiral drill bit 21. The main motor 20 is installed on the top of the mounting plate 19, and the spiral drill bit 21 is arranged 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. A working handle 22 is also provided on the top of the mounting plate 19, and the working handle 22 is arranged on both sides of the main motor 20.

[0040] The working platform 1 is provided with sliding rails 23 on both sides of the excavation hole 4, and a sliding plate 24 is slidably mounted on the sliding rails 23. The front and rear ends of the sliding plate 24 are provided with guide rods 25, and 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 via a reinforcing plate 26 . Under the action of the sliding plates 24 , the spiral digging device can slide forward and backward along the direction from the center of the excavation hole 4 to the opening 5 .

[0042] When the spiral pit digging equipment is in use, it can be slid to the top of the excavation hole 4 through the sliding plate 24. Under the action of gravity, the spiral pit 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, and a downward force is applied to the mounting plate 19 through the working handle 22, so that the spiral drill bit 21 digs a hole in the soil, and the soil in the hole is discharged upward to the surrounding area of ​​the hole along the spiral blades of the spiral drill bit 21; after the pit digging is completed, the main motor 20 is turned off, and the spiral pit digging equipment is pulled up to the top of the working platform 1 through the working handle 22, and it is slid to the rear area of ​​the excavation hole 4 through the sliding plate 24, and the spiral drill bit 21 is against the top of the working platform 1, exposing the excavation hole 4 for seedling transplanting.
