DETAILED DESCRIPTION

[0027] See also Figure 1-Figure 2 As shown, the utility model provides a hole-drilling device for greening planting, comprising a stand 1, a first telescopic assembly 2, a drive motor 3 and a drill rod 4. The first telescopic assembly 2 comprises a fixed end and a movable end extending up and down, the fixed end being fixed to the front side of the stand 1; the drive motor 3 being fixed to the movable end; the drill rod 4 being fixed to the lower end of the drive motor 3, and the outer side wall of the drill rod 4 being provided with blades 41 distributed in a spiral shape.

[0028] When the device is in use, it is only necessary to place the device next to the location where a hole needs to be dug, hold the stand 1, and drive the motor 3 to drive the drill rod 4 and the blade 41 to rotate when the movable end of the first telescopic component 2 moves up and down to achieve hole digging. After the hole digging is completed, lift the stand 1 again and move the device to the next hole digging point. The device is easy to use and flexible to start, which helps to improve the efficiency of green planting hole digging. It is more suitable for one-person operation and is flexible and convenient to move.

[0029] Here, the first telescopic assembly 2 may be an electric push rod or a hydraulic telescopic rod.

[0030] Specifically, the stand 1 includes a vertical pole 11, a fixed plate 12 and a balance pole 13. The fixed plate 12 and the balance pole 13 are arranged in parallel and spaced apart in the upper and lower directions on the front side of the vertical pole 11. The front end of the fixed plate 12 is fixed to the fixed end of the first telescopic component 2, the rear end of the fixed plate 12 is fixed to the vertical pole 11, the front end of the balance pole 13 is fixed to the movable end of the first telescopic component 2, and the rear end of the balance pole 13 is slidably connected to the vertical pole 11. The stand 1 has a simple structure and is small and easy to hold.

[0031] Furthermore, an electric telescopic rod 5 is installed between the fixed plate 12 and the balancing rod 13. The electric telescopic rod 5 drives the balancing rod 13 to move up and down, thereby driving the movable end of the first telescopic assembly 2 to move up and down along the fixed end.

[0032] In this embodiment, the first telescopic assembly 2 includes a fixed cylinder 21, a movable rod 22 and a material receiving cylinder 23. A movable groove 211 is provided at the lower end of the fixed cylinder 21, a through hole 212 is provided at the upper end of the fixed cylinder 21, and the through hole 212 is connected with the movable groove 211; the movable rod 22 is slidably arranged in the movable groove 211 along the up-down direction; the material receiving cylinder 23 is arranged at the upper end of the fixed cylinder 21, the upper end of the material receiving cylinder 23 is opened, and the lower end of the material receiving cylinder 23 is connected with the through hole 212; wherein, the fixed cylinder 21 constitutes the fixed end, and the movable rod 22 constitutes the movable end.

[0033] After the hole is dug, during the upward movement of the drill rod 4, by adding fertilizer into the material receiving barrel 23, the fertilizer can fall along the material receiving barrel 23 and through the through hole 212 and the movable groove 211 and fall into the hole.

[0034] Furthermore, a metering cylinder 27 is fixed to the top of the material receiving cylinder 23, a blocking block 24 is clamped on the inner side of the material receiving cylinder 23, the blocking block 24 is adapted to the inner size of the material receiving cylinder 23, and the blocking block 24 is connected to the movable rod 22 via a connecting rod 25.

[0035] When the drill rod 4 digs the hole to the lowest point, the blocking block 24 fits against the inner wall of the material receiving tube 23. At this time, fertilizer is added to the metering tube 27. After the hole is dug, the electric telescopic rod 5 contracts, driving the movable rod 22 to move upward, and then drives the blocking block 24 to move upward through the connecting rod 25. At this time, the blocking block 24 moves upward to open the opening at the upper end of the material receiving tube 23, and the fertilizer will flow down and fall into the pit when the drill rod 4 and the blade 41 are separated from the pit, thereby realizing accurate and quantitative delivery of fertilizer.

[0036] Preferably, the inner diameter of the receiving barrel 23 gradually decreases from top to bottom, and the blocking block 24 is clamped in the middle position of the receiving barrel 23 and fits with the inner wall of the receiving barrel 23. The side walls of the receiving barrel 23 and the blocking block 24 are arranged at an angle to ensure that the blocking block 24 can fit with the inner wall of the receiving barrel 23 only when the drill rod 4 is drilled to the lowest point. At this time, fertilizer is added to the quantitative barrel 27, so that the fertilizer can be added in an orderly and quantitative manner.

[0037] Specifically, the diameter of the movable rod 22 is smaller than the inner diameter of the movable groove 211, and at least two sliding blocks 26 are fixed at intervals on the outer wall of the movable rod 22. The sliding blocks 26 are slidably connected to the inner wall of the movable groove 211, which helps to ensure the stability of the movable rod 22 during the up and down movement, and also ensures that the waste passes through the movable groove 211 smoothly and falls into the prepared pit to avoid being blocked by the movable rod 22 or the sliding blocks 26.

[0038] Specifically, the drive motor 3 and the blade 41 are both located directly below the movable groove 211, and the inner diameter of the movable groove 211 is larger than the outer diameter of the drive motor 3, which helps to ensure that the fertilizer can accurately fall into the prepared pit when falling along the through hole 212 and the movable groove 211.

[0039] Furthermore, a bottom plate 14 is fixed to the bottom of the vertical pole 11 . The bottom plate 14 is extended to the left and right sides of the vertical pole 11 . Positioning holes 141 are respectively provided on both sides of the bottom plate 14 .

[0040] In places where the land environment is uneven, an external fixing cone can be used to pass through the positioning hole 141 and nailed into the soil to fix the base plate 14 next to the pit point, thereby ensuring that the vertical pole 11 remains vertical, thereby improving the stability of the equipment during the pit digging process.

[0041] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
