Description

Technical Field

[0001] This utility model relates to the field of sand control and afforestation technology, and in particular to a pit-digging device for sand control and afforestation projects. Background Technology

[0002] Afforestation projects for sand control and desertification prevention are crucial measures taken by humankind to combat desertification. In deserts or severely desertified areas, professionals select drought-resistant and wind-blown sand-resistant tree species such as sea buckthorn, saxaul, and poplar, based on local climate and soil conditions. Over time, these trees gradually form forests, locking in sand and reducing sandstorms. This not only improves the ecological environment but also provides habitats for surrounding wildlife. Some economically valuable tree species can even help increase the income of local residents, achieving a balance between ecological and economic benefits. During the planting process, digging devices are often required.

[0003] In daily work, it has been found that the existing digging devices have a simple structure and the working mode is limited to single-pit operation. That is, each operation cycle can only complete the digging of one pit. In the case of large-scale sand control and tree planting projects, it is difficult to dig a large number of planting pits in a short period of time, resulting in slow overall construction progress. It is difficult to meet the demand for efficient and large-scale digging, which greatly restricts the efficiency of project construction. Utility Model Content

[0008] Preferably, the drive rod is composed of a cylindrical rod and two protrusions fixed on the surface of the cylindrical rod.

[0009] Preferably, the adjustment assembly includes a bidirectional screw that is rotatably connected to the inner wall of the movable plate.

[0010] Preferably, an adjustment motor is mounted on the surface of the movable base, and the output end of the adjustment motor is fixedly connected to one end of the bidirectional screw. Through the above-mentioned components, when the adjustment motor is operating, it can drive the bidirectional screw to rotate, thereby achieving automatic adjustment.

[0011] Preferably, the connecting assembly includes a pin fixed to the lower end of the connecting shaft. The pin is inserted into the inner wall of the drill rod, and a threaded rod is inserted into the inner wall of the drill rod. The surface of the pin has a threaded hole, and the threaded rod is threadedly connected to the inner wall of the threaded hole. With the above components, during installation, the pin can be inserted into the inner wall of the drill rod, and then the threaded rod and the threaded hole will cooperate to realize the installation operation, which facilitates the replacement of drill rods of different sizes.

[0024] Specifically, the digging mechanism 4 includes a movable plate 41 that is slidably connected to the inner side of the vehicle body 1. Multiple cylinders 44 are mounted on the surface of the vehicle body 1. The output end of the cylinder 44 passes through the vehicle body 1 and is fixedly connected to the surface of the movable plate 41. A fixed seat 42 is fixedly connected to the inner wall of the movable plate 41, and two movable seats 43 are slidably connected to the inner wall. A connecting shaft 48 is rotatably connected to the inner walls of both the fixed seat 42 and the movable seat 43. A drill rod 45 is provided at the lower end of the connecting shaft 48. A connecting assembly 5 is provided between the drill rod 45 and the connecting shaft 48. A drive assembly 46 is provided on the surface of the movable plate 41 to control the synchronous rotation of multiple sets of drill rods 45. An adjustment assembly 47 is provided on the surface of the movable plate 41 to control the movable seats 43 to adjust the digging spacing.

[0025] In this implementation plan: During the digging process, the distance between the two moving seats 43 and the fixed seat 42 is first controlled by the adjusting component 47 to determine the digging distance. Then, the driving component 46 drives multiple sets of drill rods 45 to rotate synchronously, and the cylinder 44 drives the whole to move down to realize the digging operation and improve the overall work efficiency.

[0026] Specifically, the drive assembly 46 includes a drive rod 461 rotatably connected to the inner wall of the movable plate 41, worm gears 463 rotatably connected to the inner walls of the movable seat 43 and the fixed seat 42, a worm wheel 464 meshing with the worm gears 463 fixedly connected to the surface of the connecting shaft 48, the drive rod 461 being inserted into the inner wall of the multiple worm gears 463, a drive motor 462 being mounted on one side surface of the movable plate 41, the output end of the drive motor 462 being fixedly connected to the surface of the drive rod 461, and the drive rod 461 being formed by a cylindrical rod and two protrusions fixed to the surface of the cylindrical rod.

[0027] In this implementation scheme: when the drive motor 462 is turned on, the drive motor 462 can drive the drive rod 461 to rotate, the drive rod 461 drives multiple sets of worm gears 463 to rotate, and the worm gears 463, together with the worm wheel 464, can drive the connecting shaft 48 and the drill rod 45 to rotate, thereby realizing the digging operation.

[0028] Specifically, the adjustment assembly 47 includes a bidirectional screw 472 rotatably connected to the inner wall of the movable plate 41. The bidirectional screw 472 is threadedly connected to the inner walls of two movable seats 43. An adjustment motor 471 is mounted on the surface of the movable seats 43. The output end of the adjustment motor 471 is fixedly connected to one end of the bidirectional screw 472.

[0029] In this implementation scheme: when the regulating motor 471 is operating, it can drive the bidirectional screw 472 to rotate, and the bidirectional screw 472 can control the two moving seats 43 to move in the moving plate 41.

[0030] Specifically, the connecting component 5 includes a pin 52 fixed to the lower end of the connecting shaft 48. The pin 52 is inserted into the inner wall of the drill rod 45. A threaded rod 51 is inserted into the inner wall of the drill rod 45. A threaded hole 53 is opened on the surface of the pin 52. The threaded rod 51 is threadedly connected to the inner wall of the threaded hole 53. The pin 52 is arranged in a regular hexagon.

[0031] In this implementation scheme: During installation, the pin 52 can be inserted into the inner wall of the drill rod 45, and then the threaded rod 51 and the threaded hole 53 can be engaged to complete the installation operation, which facilitates the replacement of drill rods 45 of different sizes.

[0032] Working principle: When digging a hole, first turn on the adjusting motor 471. When the adjusting motor 471 is operating, it can drive the bidirectional screw 472 to rotate. The bidirectional screw 472 can control the two moving seats 43 to move in the moving plate 41, thereby adjusting the distance between the drill rods 45. After adjustment, turn on the drive motor 462. The drive motor 462 can drive the drive rod 461 to rotate. The drive rod 461 drives multiple sets of worm gears 463 to rotate. The worm gears 463, together with the worm wheel 464, can drive the connecting shaft. Rotating drill rod 48 and drill rod 45 simultaneously opens cylinder 44, which drives moving seat 43 and multiple sets of drill rods 45 to move downwards, enabling multiple sets of synchronous digging operations and improving the overall digging effect. When it is necessary to replace different drill rods 45, threaded rod 51 can be rotated. After threaded rod 51 is removed from threaded hole 53, drill rod 45 can be removed and replaced with a new drill rod 45. Insert pin 52 into the inner wall of the new drill rod 45, and then threaded rod 51 is connected to threaded hole 53 to complete the installation operation.
