Description

Technical Field

[0001] This utility model belongs to the field of seedling planting technology, and in particular to a hole-digging device for seedling planting. Background Technology

[0002] Landscape greening projects are projects that construct scenic gardens and green spaces. Planting saplings is a common practice in landscape greening projects. When planting saplings, the first step is to dig holes. Since different varieties of saplings have different sizes, the required planting hole sizes are also different. Moreover, most auger drill bits are fixedly connected to the device, making it difficult to replace auger drill bits of different sizes according to different planting hole sizes. As a result, multiple hole-digging devices need to be prepared, which increases the cost of digging holes when planting saplings.

[0003] A Chinese patent (authorization announcement number CN215912489U) discloses an efficient hole-digging device for planting seedlings, which includes: "a base, a through groove in the middle of the base, two symmetrical support plates above the two sides of the through groove, the two support plates being fixedly connected above each other by a top plate, and two symmetrical hydraulic cylinders below the top plate, the stroke end of the hydraulic cylinders being fixedly connected to a first horizontal plate."

[0004] It is evident that the cited patent document suffers from the problem of inconvenience in digging planting pits of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide a hole-digging device for planting seedlings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hole-digging device for planting seedlings, comprising a hole-digging base, an inverted U-shaped mounting frame installed on the top surface of the hole-digging base, a horizontal plate provided in the inner cavity of the mounting frame, a drive motor installed on the top surface of the horizontal plate, the output end of the drive motor passing through the horizontal plate and connected to a mounting block, a sliding groove provided on one side of the mounting block, a slider slidably provided in the inner cavity of the sliding groove, a spiral drill bit for digging the planting hole required for the seedling connected to the bottom surface of the slider, grooves symmetrically provided on the inner top and inner bottom surfaces of the sliding groove, threaded shafts rotatably connected to the inner bottom surfaces of the two lower grooves via pins, locking blocks threadedly fitted on the periphery of the two threaded shafts, two through slots symmetrically provided on one side of the slider for the threaded shafts to pass through, and locking slots for the locking blocks to pass through the inner sidewalls of the two through slots.

[0007] Preferably, vertical rods are installed on the inner bottom surfaces of the two grooves located below, and the two locking blocks are slidably sleeved on the periphery of the vertical rods.

[0008] Preferably, two hydraulic cylinders are symmetrically mounted on the top surface of the mounting bracket, and the piston rods of the two hydraulic cylinders pass through the mounting bracket and are connected and fixed to the top surface of the horizontal plate.

[0009] Preferably, the top surface of the pit-digging base is symmetrically welded with two vertical plates, and the horizontal plate is slidably sleeved on the periphery of the two vertical plates.

[0010] Preferably, the top surface of the pit-digging base is threadedly connected to a threaded rod via a screw hole, and the bottom end of the threaded rod is rotatably connected to a lifting plate via a pin.

[0011] Preferably, the bottom surface of the lifting plate is equidistantly equipped with a plurality of cones for fixing the position of the digging base to the ground.

[0012] Preferably, the top surface of the lifting plate is symmetrically welded with two limiting rods that extend through to the top of the pit base.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This hole-digging device for planting seedlings can provide power for the movement of the locking block by rotating the threaded shaft. This allows the block to be removed from the slot, eliminating the need to fix the slider and auger bit. Alternatively, the locking block can be inserted into the slot to fix the slider and auger bit. Compared to existing devices for digging holes when planting seedlings, this device can disassemble the auger bit, allowing for the replacement of different sized auger bits to dig planting holes of different sizes.

[0015] The hydraulic cylinder and drive motor provide power for the rotation and longitudinal movement of the auger bit, which can then be used to dig planting pits for planting seedlings.

[0016] By rotating the threaded rod, power can be provided for the longitudinal movement of the lifting plate, allowing the cone nail to penetrate the ground, thereby improving the stability of the digging base during digging. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The device shown is a hole-digging device for planting seedlings, including a hole-digging base 1. The bottom surface of the hole-digging base 1 is equipped with four casters, and the top surface of the hole-digging base 1 is equipped with an inverted U-shaped mounting frame 2. With the push device, it can be moved to the work area by means of the casters.

[0029] The inner cavity of the mounting frame 2 is provided with a horizontal plate 3. A drive motor 4 is installed on the top surface of the horizontal plate 3. The output end of the drive motor 4 passes through the horizontal plate 3 and is connected to a mounting block 5. A groove 6 is opened on one side of the mounting block 5. A slider 7 is slidably installed in the inner cavity of the groove 6. A spiral drill bit 8 for digging planting holes for seedlings is connected to the bottom surface of the slider 7. Two hydraulic cylinders 15 are symmetrically installed on the top surface of the mounting frame 2. The piston rods of the two hydraulic cylinders 15 pass through the mounting frame 2 and are connected and fixed to the top surface of the horizontal plate 3. After the digging base 1 is moved to the working area, the drive motor 4 is turned on, and the mounting block 5 is rotated. This rotates the spiral drill bit 8 through the groove 6 and the slider 7. Then, the hydraulic cylinders 15 are turned on, which moves the horizontal plate 3 downward, thereby moving the spiral drill bit 8 downward. The top surface of the digging base 1 is provided with a through hole for the spiral drill bit 8 to pass through, so that the spiral drill bit 8 can pass through the through hole to dig planting holes.

[0030] Two vertical plates 16 are symmetrically welded to the top surface of the pit base 1. A horizontal plate 3 is slidably sleeved on the periphery of the two vertical plates 16. When the horizontal plate 3 moves longitudinally back and forth, it will move on the periphery of the vertical plates 16, so that the vertical plates 16 can support the horizontal plate 3 and assist in its movement.

[0031] The inner top and bottom surfaces of the slide 6 are symmetrically provided with grooves 9. The inner bottom surfaces of the two lower grooves 9 are rotatably connected to threaded shafts 10 via pins. The top ends of the two threaded shafts 10 extend through to the top of the mounting block 5 and are connected to a knob. The periphery of the two threaded shafts 10 is threaded with locking blocks 11. One side of the slider 7 is symmetrically provided with two through slots 12 for the threaded shafts 10 to pass through. The inner sidewalls of the two through slots 12 are provided with locking grooves 13 for the locking blocks 11 to pass through. In the initial state, the locking blocks 11 are in the inner cavity of the locking grooves 13, fixing the position of the slider 7. When digging planting pits of different sizes, turning the knob will rotate the threaded shafts 10, thereby moving the locking blocks 11 upwards, allowing the locking blocks 11 to pass through the locking grooves 13. Once removed, the slider 7 can be released from its fixation. At this point, the operator can pull the auger bit 8 horizontally to remove the slider 7 from the groove 6 and replace it with an auger bit 8 of the appropriate size. Conversely, the slider 7 on the top surface of the replaced auger bit 8 is inserted into the groove 6, and the threaded shaft 10 passes through the through groove 12 and enters the slot 13. The slot 13 is aligned with the position of the locking block 11. Then, the knob is turned in the opposite direction to move the locking block 11 downward and into the slot 13, allowing the locking block 11 to pass through the slot 13 and enter the groove 9 below. This fixes the slider 7 and the auger bit 8, making it easier to replace auger bits 8 of different sizes. This avoids the need to prepare multiple digging devices to dig planting holes of different sizes, reducing the cost of digging holes when planting seedlings.

[0032] Vertical rods 14 are installed on the inner bottom surfaces of the two grooves 9 located below. Two locking blocks 11 are slidably sleeved on the periphery of the vertical rods 14. When the threaded shaft 10 drives the locking blocks 11 to perform longitudinal reciprocating motion, the locking blocks 11 will perform longitudinal reciprocating motion on the periphery of the vertical rods 14, which can limit the movement trajectory of the locking blocks 11 and prevent deviation. In addition, the diameter of the vertical rods 14 is smaller than the diameter of the threaded shaft 10, so the vertical rods 14 can also pass through the through groove 12 and enter the interior of the locking groove 13.

[0033] The top surface of the digging base 1 is threadedly connected to a threaded rod 17 via a screw hole. A handle is connected to the top of the threaded rod 17, and a lifting plate 18 is rotatably connected to the bottom of the threaded rod 17 via a pin. Several cones 19 are equidistantly installed on the bottom surface of the lifting plate 18 for embedding into the ground and fixing the position of the digging base 1. After the digging base 1 is moved to a suitable working area, turning the handle will rotate the threaded rod 17, thereby moving the lifting plate 18 downward so that the cones 19 can embed into the ground, thus fixing the position of the digging base 1 and preventing the digging base 1 from shifting during digging.

[0034] Two limiting rods 20 are symmetrically welded to the top surface of the lifting plate 18, extending through to the top of the pit base 1. The top surface of the pit base 1 is symmetrically provided with circular grooves for the limiting rods 20 to pass through, so that when the lifting plate 18 moves longitudinally, the limiting rods 20 will move within the circular grooves, thereby limiting the movement trajectory of the lifting plate 18 and preventing it from rotating with the threaded rod 17. The other side of the top surface of the pit base 1 is also provided with the threaded rod 17, the lifting plate 18, the conical spike 19 and the limiting rods 20, thereby improving the fixing effect of the pit base 1.

[0035] Working principle:

[0036] The hole-digging equipment for planting seedlings involves moving the digging base 1 to the working area and turning on the drive motor 4. This, in turn, rotates the auger drill bit 8 via the mounting block 5. Then, activating the hydraulic cylinder 15 moves the horizontal plate 3 downwards, thereby moving the auger drill bit 8 downwards to dig planting holes. To dig planting holes of different sizes, turning the knob rotates the threaded shaft 10, causing the locking block 11 to move upwards and be removed from the slot 13. This releases the lock on the slider 7, allowing the operator to pull the auger drill bit 8 horizontally. This allows the slider 7 to be removed from the groove 6, and a suitable auger bit 8 to be replaced. The slider 7 on the top surface of the replaced auger bit 8 is then inserted into the groove 6, and the threaded shaft 10 passes through the through groove 12 and enters the slot 13. The slot 13 is aligned with the position of the locking block 11. At this point, the knob is turned in the opposite direction, which moves the locking block 11 downward and into the slot 13, thus fixing the slider 7 and the auger bit 8. This allows for the replacement of auger bits 8 of different sizes, avoiding the need to prepare multiple digging devices to dig planting holes of different sizes, and reducing the cost of digging holes when planting seedlings.
