Description

Technical Field

[0001] The utility model relates to the technical field of fly ash cleaning, in particular to a drill bit for cleaning an ash silo. Background Art

[0002] At present, my country's power generation method is mainly thermal power generation, which is mainly generated by coal combustion. After the coal is burned, the combustion residue will be stored in the pulverized coal bin. However, the fly ash is easily compacted on the inner wall of the pulverized coal bin due to moisture, heat and other factors during storage. This compaction will form a blockage at the discharge port of the pulverized coal bin, causing great trouble for subsequent transportation. The existing manual cleaning method is to use tools such as shovels and pickaxes for cleaning, but since the compaction may contain hard substances, it is difficult for general tools to completely remove it. In view of this, it is necessary to improve the existing technology. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a drill bit for cleaning an ash silo.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A drill bit for cleaning an ash silo comprises a drill bit body, wherein the drill bit body comprises a cutter head base and a crushing scraper, wherein a plurality of detachable crushing scrapers are distributed in the circumferential direction of the cutter head base, wherein the crushing scraper extends from the bottom of the side wall of the cutter head base to the middle of the top surface, and the outer edges on both sides of the crushing scraper are linearly arrayed with semi-cylindrical blades.

[0006] Furthermore, a continuous mounting groove is provided on the top surface and side wall of the cutter head base, a first threaded hole is provided in the mounting groove, a second threaded hole corresponding to the first threaded hole is provided on the crushing scraper, and the crushing scraper is fixedly mounted on the cutter head base by a fastener, and the end of the fastener passes through the second threaded hole and is connected to the first threaded hole.

[0007] Furthermore, a mounting hole is provided at the bottom of the cutter head base.

[0008] Furthermore, the cutter head base is in the shape of a truncated cone that is smaller at the top and larger at the bottom. Beneficial Effects

[0009] The top surface and the annular surface of the utility model can be used for crushing and cutting. Holes can be drilled on the compaction to gradually clean the compaction. It has the advantages of quick installation and high crushing efficiency. When the tool reaches the end of its working life, it does not need to be replaced as a whole, only the crushing scraper needs to be replaced, which reduces maintenance and use costs.

[0013] In the figure: a drill body 1, a cutter head base 10, a crushing scraper 11, a blade 12, a mounting groove 101, and a mounting hole 102. DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0015] Example: See Figure 1 — Figure 3 As shown, a drill bit for cleaning an ash silo includes a drill body 1. The drill body 1 includes a cutter head base 10 and a crushing scraper 11. A plurality of detachable crushing scrapers 11 are distributed circumferentially of the cutter head base 10. The crushing scrapers extend from the bottom of the side wall of the cutter head base 10 to the middle of the top surface. Semi-cylindrical blades 12 are linearly arrayed on the outer edges of both sides of the crushing scraper 11.

[0016] In this embodiment, a continuous mounting groove 101 is provided on the top surface and side wall of the cutter head base 10, a first threaded hole is provided in the mounting groove 101, a second threaded hole corresponding to the first threaded hole is provided on the crushing scraper 11, and the crushing scraper 11 is fixedly mounted on the cutter head base 10 by a fastener, and the end of the fastener passes through the second threaded hole and is connected to the first threaded hole.

[0017] In this embodiment, a mounting hole 102 is provided at the bottom of the cutter head base 10, and the mounting hole 102 can be connected to an electric drill.

[0018] In this embodiment, the cutter head base 10 is in the shape of a truncated cone that is smaller at the top and larger at the bottom.

[0019] When the utility model is used, the cutter head base 10 is installed on the electric drill through the installation hole 102. The rotation of the electric drill drives the drill body 1 to rotate. The drill body 1 is placed against the hardened part of the inner wall of the pulverized coal bin to drill holes in the hardened part, and the hardened part is gradually cleaned.
