DETAILED DESCRIPTION

[0027] The following, with reference to the accompanying drawings, describes the embodiments and further explains the specific implementation methods of the utility model, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution of the utility model.

[0028] Example 1

[0029] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a drilling sampling device for highway engineering, which can realize the effect of lifting and lowering the drill bit 204, and includes a lifting part 100 and a protective part 300. The lifting part 100 includes a bottom plate 101, a through groove 102 arranged on the bottom plate 101, and a hydraulic press 103 arranged at the upper end of the bottom plate 101, and the output end of the hydraulic press 103 is provided with a sampling part 200; the protective part 300 includes a telescopic seat 301 arranged at the lower end of the bottom plate 101, a lifting groove 302 arranged on the inner surface of the telescopic seat 301, and a telescopic plate 303 arranged in the lifting groove 302.

[0030] The sampling part 200 includes a connecting plate 201 arranged at the output end of the hydraulic press 103, a motor 202 arranged between the connecting plates 201, and a drill barrel 203 arranged at the output end of the motor 202. A drill bit 204 is arranged at the lower end of the drill barrel 203, and an upper groove plate 205 is arranged at one end of the connecting plate 201 away from the motor 202.

[0031] Through the above arrangement: the drill tube 203 and the drill bit 204 are set as an integrated structure, and the drill bit 204 performs lifting movement in the groove 102, thereby realizing sampling of the road surface. The hydraulic press 103 is located on both sides of the groove 102, and is provided with two groups. The connecting plate 201 at the output end of the hydraulic press 103 is fixedly connected to the motor 202, and the lifting movement of the motor 202 is realized by means of the telescopic function of the hydraulic press 103, thereby providing a movement basis for the lifting movement of the drill bit 204.

[0032] In summary, by turning on the hydraulic press 103, the output end of the hydraulic press 103 contracts, thereby causing the connecting plate 201 to move downward. Since the connecting plates 201 on both sides are fixedly connected to the motor 202, the motor 202 moves downward, thereby driving the drill barrel 203 and the drill bit 204 to move downward. By turning on the motor 202, the output end of the motor 202 drives the drill barrel 203 and the drill bit 204 to rotate, thereby providing a guarantee for highway inspection sampling.

[0033] Example 2

[0034] Reference Figures 2-3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a buffering function for the drilling sampling equipment for highway engineering, which solves the problem that the drill bit 204 affects the sampling effect due to shaking during operation. It includes push handles 104 on both sides of the upper end of the bottom plate 101 away from the through groove 102, and a buffer part 400 is provided between the through groove 102 and the push handle 104.

[0035] The buffer part 400 includes a first fixing seat 401 and a second fixing seat 402 arranged at the upper end of the bottom plate 101, a connecting rod 403 arranged between the first fixing seat 401 and the second fixing seat 402, and a lower groove plate 404 arranged on the connecting rod 403. Rollers 405 are arranged around the lower end of the bottom plate 101.

[0036] A straight plate 206 is arranged between the lower groove plate 404 and the upper groove plate 205 via a rotating shaft, a first annular plate 406 and a second annular plate 407 are arranged on both sides of the lower groove plate 404, a third annular plate 408 is arranged at one end of the first fixed seat 401 close to the lower groove plate 404, a fourth annular plate 409 is arranged at one end of the second fixed seat 402 close to the lower groove plate 404, a short elastic member 410 is arranged between the first annular plate 406 and the third annular plate 408, and a long elastic member 411 is arranged between the second annular plate 407 and the fourth annular plate 409.

[0037] The upper groove plate 205 and the lower groove plate 404 are designed to have a groove structure on the surface. A rotating shaft is set in the groove, and the upper groove plate 205 and the lower groove plate 404 are connected through a straight plate 206 on the rotating shaft. When the upper groove plate 205 moves downward, the lower groove plate 404 moves horizontally, so as to improve the stability of the drill bit 204 during the descent process.

[0038] The provision of the roller 405 is beneficial to improving the mobility of the device, avoiding manual handling, and improving practicality.

[0039] By setting the short elastic member 410 and the long elastic member 411, when the lower groove plate 404 is offset to the left or to the right, a pulling force is applied to the lower groove plate 404 in the other direction, thereby helping the lower groove plate 404 to restore its initial state, which is beneficial to the stability of the drill bit 204 during sampling.

[0040] In summary, when the drill bit 204 is taking samples, the combination of the straight plates 206 on both sides and the hydraulic press 103 forms a support for the triangle of the motor 202, which is helpful to reduce the problem of the drill bit 204 affecting the sampling effect due to shaking. The shaking generated by the drill bit 204 during sampling can be used by the straight plate 206 to slide the lower groove plate 404 back and forth on the connecting rod 403, which plays a role in releasing the pressure of the shaking, thereby helping to offset the shaking force and improve stability.

[0041] Example 3

[0042] Reference Figure 4 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a function of shielding the sampling site of the drilling sampling equipment for highway engineering, which solves the problem of dust pollution to the environment. It includes a slide rail 105 provided on the side of the lower end of the bottom plate 101 close to the through groove 102, a slider 106 is provided on the slide rail 105, a slide rod 107 is provided on the upper end of the telescopic plate 303, a compression spring 108 is provided between the telescopic plate 303 and the lower end of the bottom plate 101, and a protrusion 109 is provided on the outer wall of the telescopic plate 303.

[0043] The slide bar 107 is fixedly connected to the telescopic plate 303, so that the downward movement of the slide bar 107 by the slider 106 drives the telescopic plate 303 to move downward, so that the upward pulling force of the compression spring 108 on the telescopic plate 303 drives the slide bar 107 to move upward, which is beneficial to the upward movement of the drill bit 204. During the rising process, the slide bar 106 loses the downward pressure of the drill bit 204, and with the help of the elastic effect of the compression spring 108, the slide bar 107 drives the slide bar 106 to move toward the direction of the groove 102, and returns to the initial state of the device, thereby improving practicality.

[0044] The slider 106 is designed to have an upper inclined surface on one side. When the drill bit 204 is lifted or lowered in the groove 102, it contacts the upper inclined surface on one side of the slider 106. Due to the pressure from the lower end face of the drill bit 204, the slider 106 will move away from the groove 102. Since the other side of the slider 106 is designed to have a lower inclined surface, it contacts the dome at the upper end of the slide rod 107. The slide rod 107 will move downward in the vertical direction along the lower inclined surface on the other side of the slider 106, causing the telescopic plate 303 to move downward, thereby wrapping the drill bit 204 and preventing the splash of gravel generated by the drill bit 204 during the sampling process.

[0045] The protrusion 109 is fixedly connected to the telescopic plate 303 . Since the protrusion 109 is engaged and slidably connected to the lifting groove 302 , the stability of the telescopic plate 303 in the upward and downward sliding connection in the telescopic seat 301 is improved.

[0046] The cross section of the slide rail 105 is designed to have a structure with a cross bar added on both sides, and the cross section of the slider 106 is designed to have a T-shaped structure inside. The cross bars on both sides of the slide rail 105 are hooked with the cross bars extending on both sides of the T of the slider 106, so as to achieve a stable sliding connection of the slider 106 on the slide rail 105, which serves as a driving medium for the downward thrust of the drill bit 204 to drive the telescopic plate 303 to move downward.

[0047] In summary, when the drill bit 204 is descending in the groove 102, it contacts the upper inclined surface of the slider 106, moving the slider 106 away from the groove 102, so that the lower inclined surface of the slider 106 drives the slide bar 107 to move downward in the vertical direction, causing the telescopic plate 303 to move downward, thereby blocking the drill bit 204. When the drill bit 204 is ascending in the groove 102 and no longer contacts the slider 106, the slider 106 loses external pressure. With the help of the elastic action of the compression spring 108, the slide bar 107 moves upward and drives the slider 106 to move toward the groove 102, thereby restoring the device to its initial state.

[0048] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
