The rotary drilling rig is common equipment for forming holes for bored piles, and is widely applied to the construction process of urban infrastructure, such as construction of building foundation pile foundations, construction of bridge pile foundations, construction of building foundation pit guard piles, construction of subway station guard piles and the like. However, in the process of taking out soil and forming holes by the rotary drilling machine, when the binding force of the dregs is too large, the dregs cannot smoothly fall from the rotary drilling bucket, so that the dregs are required to be vibrated and fall through shaking caused by forward and reverse rotation of the rotary drilling bucket, and huge vibration and noise are generated when shaking is caused by forward and reverse rotation of the rotary drilling bucket, so that the influence of disturbance on the dregs is obvious. Therefore, in urban engineering construction, construction is often stopped to avoid adverse effects of vibration and noise, and thus engineering progress is also affected. In addition, the method for cleaning the dregs is not different from the method for cleaning the dregs by hammering the rotary drilling bucket by using a large hammer, and is a simple and rough method for cleaning the dregs when the rotary drilling bucket rotates positively and negatively to generate shaking.

Drawings
FIG. 1 is a schematic diagram of a rotary drilling bucket structure before modification;
fig. 2 is a schematic structural view of the present utility model.
Description of the embodiments
The following examples are provided to illustrate the features of the present utility model and other related features in further detail to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the labels 1-5 are respectively indicated as: the drilling machine comprises a rotary drilling bucket 1, a friction drill rod 2, rotary drilling bucket teeth 3, a sectional hydraulic jack 4 and a round bulldozer blade 5.
Examples: as shown in fig. 1 and 2, the slag soil cleaning device of the rotary drilling bucket of the rotary drilling rig in this embodiment is used for cleaning slag soil in the rotary drilling bucket 1, so that the slag soil falls off from the rotary drilling bucket 1 smoothly, and the rotary drilling bucket 1 can work continuously. As shown in fig. 1, the existing rotary drilling rig comprises a rotary drilling bucket 1, wherein a friction drill rod 2 is arranged above the rotary drilling bucket 1, and the friction drill rod 2 is used for driving the rotary drilling bucket 1 to perform rotary drilling, soil taking and pore forming; the bottom of the rotary drilling bucket 1 is provided with rotary bucket teeth 3, and the rotary bucket teeth 3 are used for improving rotary drilling effect and facilitating construction.
As shown in fig. 2, the main body of the rotary drilling bucket muck cleaning device in the present embodiment comprises two parts, namely a segmented hydraulic jack 4 and a circular bulldozer blade 5, wherein the segmented hydraulic jack 4 is a power part of the cleaning device and is connected with the circular bulldozer blade 5 arranged in the rotary drilling bucket 1 to drive the circular bulldozer blade 5 to move downwards in the rotary drilling bucket 1, so as to clean muck in the rotary drilling bucket 1.
Specifically, two, three or more sectional hydraulic jacks 4 are installed at the top of the rotary drilling bucket 1, and the sectional hydraulic jacks 4 are uniformly distributed at the top of the rotary drilling bucket 1 by taking the center of a circle of the round bulldozer plate 5 as a symmetrical center; for example, when two sectional hydraulic jacks 4 are adopted, the two hydraulic jacks are symmetrically arranged by taking the center of a circle of a round bulldozer plate 5 as a symmetrical center, and the included angles are 180 degrees apart; if three sectional hydraulic jacks 4 are adopted, the included angle between the three hydraulic jacks is 120 degrees. By arranging the plurality of sectional hydraulic jacks 4, the circular bulldozer blade 5 connected with the hydraulic jacks can be ensured to be subjected to relatively balanced acting force, so that the cleaning effect of the circular bulldozer blade is ensured.
The sectional hydraulic jack 4 is composed of a plurality of sections, the sections are sleeved one by one according to the size of the section, wherein the largest section is connected with the outer wall of the top of the rotary drilling bucket 1 through a flange, and the rest sections can extend into the rotary drilling bucket 1. In the embodiment, the sectional hydraulic jack 4 can be designed to be 2-4 sections according to the moving travel requirement of the round bulldozer blade 5, and the maximum elongation is smaller than 8-10cm of the internal height of the rotary drilling bucket 1. According to the embodiment, the sectional hydraulic jack 4 is adopted, so that the round bulldozer plate 5 can be stable in the moving process and can always output a certain acting force, and the cleaning effect of the round bulldozer plate 5 on dregs is guaranteed.
The circular bulldozer blade 5 is arranged inside the rotary drilling bucket 1, and the outline shape and the size of the circular bulldozer blade are matched with the outline shape and the size of the inner outline of the rotary drilling bucket 1. The front end of each section hydraulic jack 4 penetrates through the top plate of the rotary drilling bucket 1, stretches into the rotary drilling bucket 1 and is fixedly connected with the round bulldozer blade 5. When the rotary drilling bucket 1 is used, the round bulldozer blade 5 can move along the extending direction of the rotary drilling bucket 1 under the drive of the sectional hydraulic jack 4, and when the rotary drilling bucket 1 is provided with dregs, the round bulldozer blade 5 moves downwards so as to clean out the dregs adhered to the rotary drilling bucket 1.
In this embodiment, the diameter of the circular bulldozer blade 5 is smaller than the inner diameter of the rotary drilling bucket 1 by 6-10cm, so that unnecessary scraping of the circular bulldozer blade with the inner wall of the rotary drilling bucket 1 is avoided while the cleaning effect is ensured.
Although the foregoing embodiments have been described in some detail with reference to the conception and embodiments thereof, it will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the utility model as defined in the appended claims, and thus are not described in detail herein.
