[0001] This utility model belongs to the technical field of pile hole cleaning tools, specifically, it relates to a tool for cleaning slag and soil inside anchor pile holes. Background Technology

[0002] During the construction of photovoltaic projects, drilling for ground anchor piles is frequently carried out. In areas with low rainfall, such as the Northwest, the soil is loose. After drilling with large machinery, surface collapse and soil falling from the hole wall are likely to occur, resulting in the ground anchor piles not reaching the standard depth. Repeated construction with large machinery is not economical and affects the construction progress. In addition, it is difficult to operate using existing tools such as shovels for cleaning, and it cannot meet the cleaning needs of ground anchor piles at different depths. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, and not all embodiments. Based on the spirit of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-5 As shown, this utility model embodiment provides a tool for cleaning slag in the hole of ground anchor pile, including a rotating assembly 1, a drill rod and a drill bit 8. The rotating assembly 1 includes a sleeve 2, a reinforcing rib 3 and a rotating handle 4. The outer wall of the top of the sleeve 2 is welded to one end of the reinforcing rib 3, and the other end of the reinforcing rib 3 is welded to the inner side of the rotating handle 4. The bottom end of the sleeve 2 is open, and the outer wall of the sleeve 2 near the bottom end is provided with two first bolt holes 11, which are arranged on both sides of the outer wall of the sleeve 2, and the two first bolt holes 11 are symmetrical about the central axis of the sleeve 2.

[0028] The drill rod includes a first drill rod 5 and a second drill rod 6. The outer diameter of the first drill rod 5 is slightly smaller than the inner diameter of the sleeve 2. The top end of the first drill rod 5 is provided with two second bolt holes 12, which are located on both sides of the outer wall of the first drill rod 5 and are symmetrical about the central axis of the first drill rod 5. The second bolt holes 12 are the same size as the first bolt holes 11. The top end of the first drill rod 5 is sleeved with the bottom end of the sleeve 2. One end of the bolt passes through the first bolt hole 11 and the second bolt hole 12 and is connected to the nut, thereby fixing the sleeve 2 and the first drill rod 5 together.

[0029] The first drill rod 5 has several third bolt holes 13 on its outer wall near the bottom end. These third bolt holes 13 are evenly distributed on both sides of the outer wall of the first drill rod 5 and are symmetrical about its central axis. The second drill rod 6 has several fourth bolt holes 14 on its outer wall near the top end. The number and size of the fourth bolt holes 14 are the same as those of the third bolt holes 13. The fourth bolt holes 14 are evenly distributed on both sides of the outer wall of the second drill rod 6 and are symmetrical about its central axis. One end of a bolt passes through both the third bolt holes 13 and the fourth bolt holes 14 and is connected to a nut, thereby fixing the first drill rod 5 and the second drill rod 6 together.

[0030] The arrangement of the first drill rod 5, the second drill rod 6, the third bolt hole 13, and the fourth bolt hole 14 allows for adjustment of the overall length of the drill rod according to the depth of the anchor pile hole, thereby improving the applicability of this utility model.

[0031] The second drill rod 6 is equipped with helical blades 7, which are fitted into the bottom of the second drill rod 6 and welded at the contact points. The area of ​​the helical blades 7 increases sequentially from bottom to top. The helical blades 7 are preferably made of steel and have downward-curved grooves to facilitate soil removal and prevent soil from falling off.

[0032] The drill bit 8 includes a drill bit steel tube 9 and a cross-shaped drill bit 10. The top end of the drill bit steel tube 9 is welded to the bottom end of the second drill rod 6, and the bottom end of the drill bit steel tube 9 is welded to the cross-shaped drill bit 10. The cutting area of ​​the cross-shaped drill bit 10 increases sequentially from bottom to top.

[0033] The rotating handle 4 is a circular ring structure with a diameter that is one-third of the length of the drill rod. The first drill rod 5 and the second drill rod 6 are circular steel pipes.

[0034] In practice, hold both ends of the rotating handle with both hands, insert it vertically into the hole that needs to be cleaned, and rotate the handle clockwise to make the spiral blades below rotate downwards. When the grooves of the spiral blades are full of slag, lift the hole upwards and clean off the slag adhering to the spiral blades.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
