[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A hole-digging machine for planting vegetation to prevent and control desertification includes:

[0029] The drive assembly 1 has a drill bit 2 connected below it. The drive assembly 1 is used to drive the drill bit 2 to rotate and excavate the planting hole. A support assembly 3 is snapped onto the outside of the drill bit 2. The support assembly 3 can be separated from the drill bit 2 and is used to support the inner wall of the planting hole.

[0030] The drive assembly 1 includes a mounting bracket 11 with handles 12 on both sides. A power source 13 is provided on the top surface of the mounting bracket 11, and the output shaft of the power source 13 passes through the mounting bracket 11 and is connected to a transmission sleeve 14.

[0031] The power source 13 can be a small single-cylinder gasoline engine, using gasoline as fuel to provide power. It is suitable for long-term outdoor operation. The power source 13 is fixedly mounted on the top surface of the mounting bracket 11 with bolts. The handles 12 on both sides of the mounting bracket 11 make it easy for the operator to maintain the position of the power source 13, allowing for single-person or two-person operation.

[0032] The top of the transmission sleeve 14 is engaged with the output shaft of the power source 13. The bottom inner side of the transmission sleeve 14 is symmetrically provided with locking blocks 15. The bottom outer side of the transmission sleeve 14 is symmetrically threaded with locking screws 16. The head of the locking screws 16 passes through the transmission sleeve 14 and extends into the interior of the transmission sleeve 14.

[0033] The drill bit 2 includes a drill shaft 21, the top of which is engaged with the transmission sleeve 14. Four spiral plates 22 are evenly arranged on the outer side of the drill shaft 21, and the inner diameter of the support assembly 3 is the same as the outer diameter of the spiral plates 22.

[0034] The spiral direction of the spiral plate 22 is clockwise.

[0035] The top of the drilling shaft 21 is symmetrically provided with slots 23, which are adapted to the locking block 15. Screw holes 24 are symmetrically provided between the slots 23, and the screw holes 24 are threadedly connected to the locking screws 16.

[0036] The top of the drilling shaft 21 is symmetrically welded with connecting rods 25, and the support assembly 3 is snapped into the connecting rods 25.

[0037] The connecting rod 25 is located between the clamping groove 23 and the spiral plate 22, and is perpendicular to the drilling shaft 21.

[0038] The support assembly 3 comprises two half-cylinder sleeves 31 which are slidingly connected and clamped together, and two digging teeth 34 are welded to the bottom of the two half-cylinder sleeves 31.

[0039] The two half-cylinder sleeves 31 can be spliced into a cylinder. The two vertical surfaces of a single half-cylinder sleeve 31 are provided with a clamping groove 32 and a clamping block 33, and the clamping groove 32 and the clamping block 33 on the two half-cylinder sleeves 31 are matched with each other. After the two half-cylinder sleeves 31 are clamped with each other, they can only slide in the axial direction.

[0040] The top of the half-cylinder sleeve 31 is provided with a mounting groove 35 which spirally penetrates the top surface of the half-cylinder sleeve 31, and the connecting rod 25 is clamped with the mounting groove 35 and can slide along the mounting groove 35.

[0041] The spiral direction of the mounting groove 35 is the same as the spiral direction of the spiral plate 22.

[0042] When the power source 13 is working, the output shaft of the power source 13 rotates clockwise, thereby driving the drill bit 2 to rotate clockwise through the transmission sleeve 14, and the rotation of the drill bit 2 can drive the support assembly 3 to rotate clockwise through the connecting rod 25, thereby realizing excavation. Since the spiral direction of the mounting groove 35 is the same as the spiral direction of the spiral plate 22, the connecting rod 25 will not fall off during excavation.

[0043] After the excavation is completed, the drill bit 2 is rotated counterclockwise, the half-cylinder sleeve 31 is not rotated due to the extrusion and friction of the sand on the outside, and the connecting rod 25 can slide out along the mounting groove 35, thereby realizing the separation of the drill bit 2 and the support assembly 3.

[0044] The fixed sleeve 36 is threadedly connected to the outside of the half-cylinder sleeve 31 and below the mounting groove 35, and the bottom surface of the fixed sleeve 36 is welded with a limiting plate 37.

[0045] The fixed sleeve 36 is used to fix the two half-cylinder sleeves 31, so as to avoid the relative sliding of the half-cylinder sleeves 31 during drilling.

[0046] Controlling the rotation of the fixed sleeve 36 can control the position of the fixed sleeve 36 on the half-cylinder sleeve 31, thereby controlling the height of the limiting plate 37. When the limiting plate 37 contacts the ground, it can limit the downward movement of the half-cylinder sleeve 31, thereby limiting the drilling depth.

[0047] It should be noted that when the fixed sleeve 36 is rotated counterclockwise, it moves downward, and when it is rotated clockwise, it moves upward.

[0048] The operator using the device fixes the two half-cylinder sleeves 31 by the cooperation of the clamping grooves 32 and the clamping blocks 33, so as to ensure that the top surfaces of the two half-cylinder sleeves 31 are flush.

[0049] The fixing sleeve 36 is installed outside the half-cylinder sleeve 31 to fix the half-cylinder sleeve 31.

[0050] The drilling shaft 21 is inserted into the transmission sleeve 14 and fixed by the locking screw 16.

[0051] The half-cylinder sleeve 31 is sleeved from the bottom of the drill bit 2 until the connecting rod 25 is inserted into the installation groove 35.

[0052] The fixing sleeve 36 is rotated to adjust the height of the limiting plate 37 and the required drilling depth.

[0053] The drill bit 2 and the support assembly 3 are kept vertical by the handle 12, the bottom end of the drill bit 2 and the support assembly 3 is aligned with the place to be excavated, the power source 13 is controlled to work to drive the drill bit 2 and the support assembly 3 to rotate.

[0054] The drill bit 2 and the support assembly 3 rotate to start excavating the ground, and the sand excavated by the drill bit 2 is spirally lifted along the spiral plate 22 and discharged from the top of the half-cylinder sleeve 31.

[0055] When the limiting plate 37 contacts the ground, the power source 13 is stopped, the drill bit 2 is counterclockwise rotated by holding the transmission sleeve 14, the connecting rod 25 is separated from the installation groove 35, and then the drill bit 2 is pulled out.

[0056] When the drill bit 2 is pulled out, the limiting plate 37 can be stepped on to prevent the support assembly 3 from being pulled out.

[0057] The plant is thrown from the top of the half-cylinder sleeve 31, then the fixing sleeve 36 is rotated out, and then the two half-cylinder sleeves 31 are pulled out, the hole is automatically filled by the loose characteristics of the sand or the excavated soil is backfilled.

[0058] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
