Description
Technical Field
The utility model belongs to the technical field of construction equipment, concretely relates to auger stem mud scraping device.
Background
Auger stem can constantly take out a large amount of earth in the work progress, and earth glues on the helical blade of drilling rod, and partial earth can spill around auger stem along with the drilling rod promotes, influences construction site safety to unrestrained earth clearance is also relatively more inconvenient, and remaining earth also can influence normal construction on the drilling rod. Because the manual work has shortcomings such as low efficiency, high labor intensity and the like to the mud scraping of the spiral drill rod, the mud scraping equipment is usually installed on a spiral drill rod frame, however, some existing mud scraping equipment need to be driven by a motor, not only is the maintenance inconvenient, but also the cost is increased, and the defects of unreasonable design, short service life, need of integral replacement and the like exist. For this reason, it is necessary to develop a mud scraper for auger which can solve the above problems.
Disclosure of Invention
An object of the utility model is to provide a mud device is scraped to auger stem.
The utility model aims at realizing like this, including the runner and scrape the mud blade, be equipped with a plurality of equidistant mount table along the runner side, the mount table tip is equipped with square jack, and the mount table is equipped with the installation through-hole that runs through from top to bottom, and the installation through-hole passes square jack, it is oval blade to scrape the mud blade, the major axis one end of scraping the mud blade is equipped with square installation handle, is equipped with waist type through-hole on the square installation handle, the parallel minor axis with oval blade of waist type through-hole, during square installation handle inserted the square jack of mount table, the bolt passed the installation through-hole of mount table and the waist type through-hole of square installation handle, and the nut is installed to the bolt tip, makes square installation handle can follow waist type through-hole, removes in the square jack of mount table.
The utility model has the advantages that: the utility model has reasonable structure design and convenient use, can effectively ensure the mud scraping effect and has long service life; the utility model adopts a detachable structure, which is convenient for replacement and maintenance on one hand, and can slightly move along the waist-shaped through hole on the other hand, thus being beneficial to the attachment of the mud scraping blade and the helical blade, thereby improving the mud scraping effect and reducing the mud residual quantity; the utility model discloses need not motor drive, can rotate along with auger stem rotates, but the energy saving.

FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic plan view of the scraper blade and the square mounting shank;
FIG. 3 is a schematic cross-sectional view taken along line A-A of FIG. 2;
in the figure: the method comprises the following steps of 1-rotating wheel, 2-mud scraping blade, 3-mounting table, 4-square mounting handle, 5-waist-shaped through hole and 6-rotating shaft.
Detailed Description
The following description of the present invention is provided with reference to the accompanying drawings, which are not intended to limit the present invention in any way, and any alterations or replacements made based on the teachings of the present invention are all within the protection scope of the present invention.
As shown in fig. 1-3 the utility model discloses a runner 1 and scrape mud blade 2 are equipped with a plurality of equidistant mount table 3 along runner 1 side, and 3 tip of mount table are equipped with square jack, and the mount table 3 is equipped with the installation through-hole that runs through from top to bottom, and the installation through-hole passes square jack, it is oval blade to scrape mud blade 2, the major axis one end of scraping mud blade 2 is equipped with square installation handle 4, is equipped with waist type through-hole 5 on the square installation handle 4, the parallel minor axis with oval blade of waist type through-hole 5, square installation handle 4 inserts in the square jack of mount table 3, and the bolt passes the installation through-hole of mount table 3 and the waist type through-hole 5 of square installation handle 4, and the nut is installed to the bolt tip, makes square installation handle 4 can follow waist type through-hole 5, removes in the square jack of mount table 3.
Each mounting platform 3 is provided with two mounting through holes, and each square mounting handle 4 of the mud scraping blade 2 is provided with two waist-shaped through holes 5.
The number of the mounting tables 3 and the mud scraping blades 2 is 6.
Scrape mud blade 2 for turning round the shape blade, turn round the angle of angle alpha and be 77, turn round the shape blade and be that the blade is whole to be the structure of certain torsion form, its effect reduces the probability of taking place the sticking of drill with perpendicular conflict of drilling rod helical blade greatly, and then clears away earth smoothly.
The runner 1 and the mounting table 3 are of an integrated structure.
The center of the rotating wheel 1 is connected with the spiral drill rod rack through a rotating shaft 6.
The utility model discloses theory of operation and working process: before use, the center of the rotating wheel 1 of the device is connected with a spiral drill rod rack through a rotating shaft 6, the rotating wheel 1 and the mud scraping blades 2 of the device are vertically arranged, and a part of the mud scraping blades 2 are lapped on spiral blades of a spiral drill rod; when the mud scraper is used, the auger stem rotates to continuously take out mud, meanwhile, the mud scraping blades 2 which are put on the auger blades scrape the mud which continuously rises, and in the mud scraping process of the mud scraping blades 2, the mud scraping blades 2 slightly move upwards along the waist-shaped through holes 5, so that the mud scraping blades 2 are favorably attached to the auger blades, the mud scraping effect is improved, and the mud residual quantity is reduced; in the rotating process of the auger stem, the mud scraping blades 2 and the rotating wheel 1 are driven to rotate, so that continuous mud scraping is realized, and the hung mud falls at a fixed position, so that uniform collection is facilitated; the rotating wheel 1 is driven to rotate, and the motor is not required to drive actively, so that energy can be saved.
