Detailed Description

The invention will be further described with reference to specific examples, which are intended to be illustrative only and not to limit the scope of the invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents also fall within the scope of the appended claims.

Referring to fig. 1 and 2, the utility model provides a technical solution: the utility model provides a spiral drilling machine, including frame 1, the internally mounted of frame 1 has hob 2 and helical blade 3, helical blade 3 fixed mounting is at the surface of hob 2, frame 1's left and right sides fixed mounting has adjusting device 4, adjusting device 4's front side is rotated and is installed scraper 6, adjusting device 4 includes polished rod 41, shift ring 43 and spring 45 have been cup jointed to polished rod 41's surface, the inner of spring 45 and frame 1's fixed surface assembly, the outer end of spring 45 and the inboard fixed surface assembly of shift ring 43, the preceding fixed surface mounting of shift ring 43 has ring body 42, the inside fixed mounting of ring body 42 has the outer lane of bearing 44.

A lifting motor connected with an external power supply on the frame 1 drives the screw rod 2 and the screw blade 3 to lift and rotate; when the scraping plate 6 scrapes the silt between the spiral blades 3 and meets the flange at the joint, the flange pushes the scraping plate 6 outwards, so that the scraping plate 6 moves outwards through the bearing 44, the ring body 42 and the moving ring 43, the spring 45 is stretched, and the flange is reset through the rear spring 45, so that the scraping plate 6 is restored, and the silt is continuously cleaned.

The scraper 6 comprises a rotating rod 62 fixedly arranged inside an inner ring of the bearing 44, 5 connecting rods 63 are uniformly and fixedly arranged on the outer surface of the rotating rod 62, a scraper 61 is fixedly arranged at the outer end of each connecting rod 63, and an inclined surface 64 matched with the spiral blade 3 is formed in the lower surface of each scraper 61.

When the spiral blade 3 rotates, the scraping blade 61 blocks and scrapes the silt on the spiral blade, and the inclined surface 64 is matched and attached to the upper surface of the spiral blade 3, so that the soil removing effect is good; the scraping blade 61 on the upper side rises along with the spiral blade 3, is matched with the connecting rod 63, the rotating rod 62 and the bearing 44, rotates out of the spiral blade 3 gradually, meanwhile, the other scraping blade 61 on the lower side enters the spiral blade 3, and the soil scraping plates 6 on the two sides work and are matched at the same time, so that all the silt can be scraped.

The distance between the left polish rod 41 and the right polish rod 41 is equal to the pitch between the spiral blades 3. The polish rods 41 on the left side and the right side are installed in a staggered mode, the distance is one spiral blade 3 rotating distance, and therefore part of silt remained when the scraping blades 61 on one side are switched can be scraped by the scraping blades 61 on the other side, and the silt is removed completely.

The scraping blade 61 is of a similar circular structure, and a gap exists between the scraping blade 61 and the upper spiral blade 3. A gap is reserved between the scraping blade 61 with the similar circular structure and the spiral blade 3, so that the scraping blade 61 can smoothly rotate in and out of the spiral blade 3.

The two ends of the inclined surface 64 are opened with circular arcs 7. The arc 7 can smoothly and smoothly contact the screw blade 3 when the wiper blade 61 rotates, and prevent the wiper blade from being stuck.

The outer end of the polish rod 41 is screwed with a baffle ring 5. The baffle ring 5 screwed at the left end of the polish rod 41 can play a role of safety protection, and the moving ring 43 and the spring 45 which are sleeved outside the polish rod 41 are prevented from accidentally sliding.

The working principle is as follows: a lifting motor connected with an external power supply on the frame 1 drives the screw rod 2 and the spiral blade 3 to lift and rotate, and the silt soil is sent out along the spiral blade 3; the scraping blades 61 are matched with the connecting rod 63, the rotating rod 62 and the bearing 44 to gradually rotate out of the spiral blade 3, meanwhile, the other scraping blade 61 on the lower side enters the spiral blade 3, and the soil scraping plates 6 on the two sides work and are matched at the same time, so that all the silt can be scraped; run into the protruding flange of helical blade 3 junction, or when the hob 2 withdraws from fast, doctor-bar 61 moves to the outside through bearing 44, ring body 42, shift ring 43, extension spring 45, and spring 45 resets after the completion, continues to clear up silt soil, has fine adjustment ability, when avoiding butt joint protruding flange and withdrawing from the hob 2 fast, extrudees scraper 6, leads to the doctor-bar card to pause, collapses to break up even, and the protection is effectual, convenient to use.
