Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an automatic mud cleaning device for a spiral drill pipe. Background Art

[0002] The long auger drill is widely used in foundation pit support and foundation treatment projects due to its simple form, convenient assembly and disassembly, high construction efficiency, low construction noise, low energy consumption, environmental protection and other advantages. When the long auger drill works, it drills spirally, and the soil body is replaced with the spiral blades. Due to the high water content and large viscosity of cohesive soil, after the drill pipe is lifted, it often adheres to the drill pipe and the blades and cannot be cleaned in time. Moreover, the length of the long auger drill pipe is relatively long, which can reach 15-30 meters. Once the clay blocks are not cleaned in time and are lifted to a high place with the drill pipe, there is a safety hazard of falling objects from a height, threatening the personal safety of ground operators. Traditionally, the workers at the construction site generally use shovels to remove the attached soil. The cleaning effect is greatly affected by the subjective initiative of the workers, there are many uncertain factors, the actual inspection effect at the construction site is not good, the labor intensity of the workers is high, and the efficiency is low. For this reason, some automatic mud cleaning devices for spiral drill pipes have been invented. For example, a long auger drill pipe mud cleaning device for soft soil foundation disclosed in Patent CN202320009136.3 uses a scraping rod extending into the drill pipe to knock down the silt between the spiral blades to realize the cleaning of the drill pipe, which has the advantages of high efficiency and good safety. However, the structure of this device is relatively complex. Especially the installation structure in which the scraping rod is fixed on the outer periphery of the connecting wheel through the connecting plate and bolts results in poor structural strength, cumbersome assembly and disassembly, high cost, and it is difficult to disassemble due to rust caused by the influence of silt. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an automatic mud cleaning device for a spiral drill pipe with a simpler structure, higher structural strength, more convenient and faster assembly and disassembly, and lower cost in view of the defects existing in the prior art.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme: an automatic mud cleaning device for a spiral drill pipe, comprising a rotating disk, a plurality of mud cleaning arms and connecting arms. Each mud cleaning arm is connected to the rotating disk through the connecting arm. The rotating disk is installed through a rotating shaft to form a rotatable structure. The mud cleaning arms rotating with the rotating disk take turns to extend into the spiral grooves between the spiral blades of the spiral drill pipe. Its characteristics are: the mud cleaning device is made of hard materials, the mud cleaning arms and the connecting arms and the rotating disk are of an integral structure and are integrally formed; the rotating shaft is fixedly connected to the center of the rotating disk to form a structure that can rotate synchronously.

[0005] Further, it includes four mud cleaning arms and four connecting arms. Each mud cleaning arm is arranged at the periphery of the rotating disk at a uniform interval through the connecting arm, and the whole mud cleaning device forms a "卐" - shaped structure.

[0006] Furthermore, the mud cleaning device is made of metal or injection-molded by engineering plastics.

[0007] Furthermore, a fixed disk is arranged on the rotating shaft, the rotating disk is locked and fixed to the fixed disk by a plurality of bolts, and the part of the rotating shaft extending in front of the fixed disk is inserted into the rotating disk.

[0008] Furthermore, a mounting mechanism is arranged beside the spiral drill rod, the mounting mechanism is arranged on the drill rod body, and the rotating shaft is movably mounted on the mounting mechanism to form a position-adjustable structure and a rotatable structure.

[0009] Furthermore, a mud cleaning device is provided on one side of the auger rod or a mud cleaning device is provided on each of the two sides.

[0010] The utility model designs the mud cleaning arm, the connecting arm and the rotating disk into an integrated structure. When the device needs to be disassembled for cleaning, the entire device can be directly removed from the mounting mechanism without the need to separately assemble or disassemble the mud cleaning arm. This not only simplifies the structure and reduces the cost, but also makes the device more convenient to assemble and disassemble, and has a higher structural strength. There is no problem in which the mud cleaning arm cannot be disassembled due to rust. BRIEF DESCRIPTION OF THE DRAWINGS
