Referring to fig. 4, in order to enhance the mud scraping capability of the auger, the bottom of the mud scraping plate 7 is provided with the scraping teeth 12, and the scraping teeth 12 are wave-shaped long strips, so that the mud is scraped through the wave-shaped strips on the mud scraping plate 7.
The working principle of the invention is as follows:
when in use: the frame 1 is fixed to a proper position, then the hydraulic motor 2 is pushed forwards through the propelling device 3, the hydraulic motor 2 drives the auger stem 4 to rotate, the composite tower-shaped drill bit 5 rotates, the composite tower-shaped drill bit 5 is used for drilling, and the auger on the auger stem 4 transports soil;
in the process of conveying the soil, the auger stem 4 positioned at one end of the composite tower-shaped drill bit 5 rotates, the soil is conveyed to the side of the propelling device 3 through the auger, and when the auger stem 4 conveys the soil, at the moment, the baffle 10 positioned at the auger bending part on the auger stem 4 is pushed by the soil, the soil is conveyed upwards when the auger stem 4 rotates continuously due to the pushing of the soil, the baffle 10 is pushed to be erected through the soil, when the auger stem 4 conveys the soil continuously, the baffle 10 and the mud scraping plate 7 are pushed to realize the sliding of the guide frame 8 on the auger stem 4, and simultaneously, the inner side wall and the outer side wall of the auger on the auger stem 4 of the mud scraping plate 6 slide synchronously to realize the conveying of the soil;
meanwhile, the baffles 10 arranged at intervals realize that the auger on the auger stem 4 is in a box type to convey the soil upwards, so that the fine-particle soil is conveyed, and after the mud scraping plate 7 is erected, the inner side wall of the auger on the auger stem 4 is scraped by the scraping teeth 12, so that the soil attached to the inner wall of the auger on the auger stem 4 is scraped;
and, when the baffle 10 for conveying the soil is close to the propelling device 3 and passes through the bending part at the other end of the auger stem 4, the baffle 10 can slide on the outer side wall of the auger on the auger stem 4, so as to be conveyed to the direction of the composite tower-shaped drill bit 5 for circularly conveying the soil, and in the conveying process, the baffle 10 erected on the inner side wall of the auger on the auger stem 4 can scrape the plane of the baffle 10 on the outer side wall of the auger on the auger stem 4, and further scrape one side of the baffle 10, meanwhile, the arc-shaped surface on the pushing baffle 10 is close to the outer side wall of the auger on the auger stem 4, when the outer side wall of the auger on the auger stem 4 is scraped through the scraping tooth 12, the arc-shaped surface slides with the outer side wall of the auger on the auger stem 4, further scraping the arc-shaped surface of the baffle 10, which mainly depends on the friction with the outer side wall of the auger on the auger stem 4, when the baffle 10 is conveyed to the bottom of the auger stem 4 and is close to one side of the composite tower-shaped drill bit 5, the soil is circularly conveyed in a box separation mode, and overload drilling is carried out on the auger stem 4 without depending on too much soil in the conveying process.
