[0002] A hole reamer is a commonly used hole reamer in geological exploration. There are many types of hole reamer on the market, such as barrel hole reamer, rock hole reamer, etc. The drill bits of these hole reamer are mostly solid structures, and the drill bit parts mostly adopt a conical structure. The soil layer is first developed from the front end with a small radius, then gradually sinks, and finally a cylindrical hole is drilled from the upper part of the drill bit.

[0003] After searching, for example, the utility model patent with Chinese patent publication number CN220645929U discloses a hole expander for geological exploration, including an L-shaped counterweight plate, a water tank is fixedly installed at the bottom of the inner cavity of the L-shaped counterweight plate, a water box is fixedly connected to the bottom of the left side of the L-shaped counterweight plate, a spray head is connected to the left side of the water box, and a conveying component is fixedly arranged on the left side of the top of the water tank. The utility model can expand the land for hole exploration by arranging an L-shaped counterweight plate, a cross plate, a drive box, a screw, a servo motor, a rectangular plate, a frame, a rotating motor, a mounting plate and a hole expander. By arranging an L-shaped counterweight plate, a water tank, a water box, a spray head, a water pump, a suction pipe and a drain pipe, dust can be reduced on the land.

By arranging the above structure, the hole expanding device has the advantage of having a dust reduction function when in use, effectively avoiding dust flying and affecting the health of the staff, thereby meeting the customer's usage needs.

[0004] When using a hole reaming device in geological survey work, due to the physical nature of the operation, it involves cutting and crushing of soil and rocks. In this process, soil will be cut off and may be ejected. These materials may splash onto people under high-speed rotation. Although the above-mentioned utility model patent can spray and land the raised dust, no effective protection measures are taken for large particles of debris, and debris and soil blocks can still be raised, so there is a certain risk during operation. Therefore, a hole reaming device for geological engineering survey is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, a hole expanding device for geological engineering survey includes a shell 1, an auxiliary mechanism 2 is arranged inside the shell 1, a soil drilling assembly 3 is arranged at the bottom of the auxiliary mechanism 2, and a protective mechanism 4 is arranged at the bottom of the shell 1.

[0023] The auxiliary mechanism 2 includes a motor 201, which is fixedly installed on the top of the shell 1. A threaded rod 202 extending into the interior of the shell 1 is fixedly installed at the output shaft of the motor 201, and the outer surface of the threaded rod 202 is threadedly connected to a threaded sleeve 203 slidably installed on the inner wall of the shell 1.

[0024] Through the cooperation of the motor 201, the threaded rod 202 and the threaded sleeve 203, the lifting plate 401 can be driven to move up and down, so that the retaining curtain 406 can be opened.

[0025] The protection mechanism 4 includes a lifting plate 401, and the lifting plate 401 is fixedly installed on the bottom of the threaded sleeve 203. The outer surface of the lifting plate 401 is hinged with three support rods 402. The outer surface of the outer shell 1 is provided with three slide grooves 403. Slide blocks 404 are slidably installed inside the three slide grooves 403. Connecting rods 405 are hinged between the three support rods 402 and the corresponding slide blocks 404. A soil retaining curtain 406 is arranged between every two adjacent support rods 402.

[0026] The three support rods 402 are evenly distributed on the outer surface of the lifting plate 401, and the three support rods 402 form an umbrella-like structure. When the lifting plate 401 moves up and down, and the slider 404 and the slide groove 403 slide together, the three support rods 402 rotate and open, thereby opening the retaining curtain 406. Under the action of the retaining curtain 406, when the support rods 402 are opened, they can open the retaining curtain 406, and isolate the debris, soil blocks, etc. generated during the drilling process on the inner side of the retaining curtain 406 to prevent these materials from splashing onto the operator, thereby reducing the safety risk at work. In addition, the three support rods 402 are distributed in an umbrella-like structure, which achieves a stable support effect.

[0027] The soil drilling assembly 3 includes a cylinder 301, the cylinder 301 is fixedly installed at the bottom of the lifting plate 401, a box body 302 is fixedly installed at the bottom of the cylinder 301, a motor 303 is fixedly installed inside the box body 302, and a drill rod 304 is fixedly installed at the output shaft of the motor 303.

[0028] A circular hole is opened at the bottom of the box body 302 on the outer surface of the drill rod 304. The bottom of the drill rod 304 passes through the circular hole and extends to the outside of the bottom of the box body 302. The drilling depth can be adjusted by the cylinder 301, and the motor 2 303 is used to drive the drill rod 304 to rotate for drilling.

[0029] Grips are fixedly installed on both sides of the shell 1, and both grips are provided with anti-slip grooves. When in use, the operator can hold the grips with both hands. The anti-slip grooves on the grips can increase the friction between the hands and the grips, thereby providing better holding stability.

[0030] When implementing, follow these steps:

[0031] 1) First, the motor 201 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the threaded sleeve 203 to slide downward inside the housing 1, and the threaded sleeve 203 drives the lifting plate 401 to move downward;

[0032] 2) When the lifting plate 401 moves downward, the three support rods 402 are driven to rotate. During the rotation of the three support rods 402, one end of the three support rods 402 drives the slider 404 to slide in the slide groove 403, so that the three support rods 402 are in an open state and contact the ground for support;

[0033] 3) As the three support rods 402 are stretched out, the retaining curtain 406 is opened;

[0034] 4) Finally, the cylinder 301 drives the drill rod 304 to move downward, and the motor 2 303 drives the drill rod 304 to rotate to drill the soil. The debris and soil blocks generated during the drilling are blocked in the retaining curtain 406.

[0035] In summary, the hole expanding device for geological engineering survey, by providing the auxiliary mechanism 2 and the protective mechanism 4, can make the three support rods 402 contact the ground to stably support the device, and the open state of the three support rods 402 can open the retaining curtain 406, and isolate the debris and the like generated during drilling inside the retaining curtain 406 to avoid splashing onto people, which can not only improve the supporting stability of the device, but also improve the safety during use.
