Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a soil sampling device for highway engineering supervision. Background Art

[0002] Before building a highway, it is necessary to take soil samples from the soil in the construction area to judge whether it is necessary to reinforce the land in this area. Through multi-area judgment, and finally calculate the route of the highway passing through the areas that do not need to be reinforced, so as to save costs to the greatest extent. Soil sampling is an essential task in highway engineering, and the sampler is a commonly used device for project supervision. The sampler can take soil samples to obtain relevant information about the soil, so as to ensure the construction of highway engineering.

[0003] The currently commonly used method is that workers use a steel soil-lifting drill bit to manually twist and drill for soil-lifting operations, or use a small drilling machine for drilling. The method of manually drilling and lifting soil has low efficiency, and the power of manual drilling is limited. When encountering complex geology, the power source is insufficient to drill to an effective depth. The small drilling rig has high requirements for the construction site and is not convenient enough for installation, fixation and positioning, and is not suitable for soil sampling operations in complex sites during highway engineering construction.

[0024] Using the overall structure of the device, when the supervisor conducts soil sampling for highway engineering construction, by pushing the push rod 4, the sampling vehicle is pushed to the calibrated sampling point, aligning the positioning hole 3 with the calibration point. Then, lock the universal wheels 11 and adjust the height of the positioning cone 5. Use tools to drive the positioning cone 5 into the ground for fixation. Subsequently, start the drive motor 7 through the control switch 12. Under the action of the drive motor 7, the lead screw 8 fixed on the output shaft starts to rotate and, under the action of the ball screw bearing 9, moves up and down along the motor support 6. The soil auger 10 drills into the ground. After drilling to the specified depth, make the drive motor 7 rotate in reverse at a slow speed through the control switch 12 to lift the drill bit, completing the sampling operation.

[0025] As Figures 1-6 shown, the motor support 6 includes several vertical rods 601. At the bottom and top of the vertical rods 601, several cross rods 602 are respectively fixedly connected. Between the cross rods 602 at the bottom of the frame 1, a pair of connecting rods 603 are fixedly connected. At the center of the outer wall of the connecting rod 603, a ball screw bearing 9 is fixedly connected. The ball screw bearing 9 is sleeved on the outer wall of the lead screw 8. At the bottom of the drive motor 7, a motor base 701 is fixedly connected. The motor base 701 is provided with several socket holes 702. The motor base 701 is movably sleeved on the center of the outer wall of the vertical rod 601 through the socket holes 702.

At the top of the pin shafts 102, a connection pin 103 is movably connected. At the bottom of the soil auger 10, a top cone 104 is fixedly connected.

[0026] Before soil sampling, first insert the connection pin 103 of the soil auger 10 into the connection hole 802 of the drill bit connection plate 801 and use the connection pin 103 for clamping and fixation. During sampling, the drive motor 7 starts and stops under the control of the control switch 12. Under the driving force of the drive motor 7, the lead screw 8 starts to rotate at a high speed. Under the action of the top cone 104, the soil auger 10 fixed at the bottom of the lead screw 8 drills into the soil.

[0029] Working principle: Using the overall structure of the device, when the supervisor conducts soil sampling for highway engineering construction, by pushing the push rod 4, the sampling cart is pushed to the calibrated sampling point. Align the positioning hole 3 with the calibration point, then lock the universal wheels 11, and adjust the height of the positioning cone 5. Use tools to drive the positioning cone 5 into the ground for fixation. Subsequently, start the drive motor 7 through the control switch 12. Under the action of the drive motor 7, the lead screw 8 fixed on the output shaft starts to rotate, and under the action of the ball screw bearing 9, it moves up and down along the motor bracket 6. The soil drill 10 drills into the ground. After drilling to the specified depth, the drive motor 7 is made to rotate in the reverse direction at a slow speed through the control switch 12 to lift the drill bit, completing the sampling operation. Before soil sampling, first insert the connecting pin 103 of the soil drill 10 into the connecting hole 802 of the drill bit connecting plate 801 and use the connecting pin 103 for clamping and fixing. During sampling, the drive motor 7 starts and stops under the control of the control switch 12. Under the driving force of the drive motor 7, the lead screw 8 starts to rotate at a high speed. The soil drill 10 fixed at the bottom end of the lead screw 8 drills into the soil under the action of the top cone 104. Under the action of the ball screw bearing 9, the motor base 701 of the drive motor 7 moves up and down along the vertical rod 601 to ensure the stability of the lifting. The spiral blade 101 can effectively drill and sample the soil. Before soil sampling, push the cart to the designated calibration empty position through the push rod 4, then adjust the matching height of the limit pin 502 and the limit pin hole 501 to adjust the height of the positioning cone 5. Use tools to drive the positioning cone 5 into the surface layer of the ground, and lock the universal wheels 11 at the same time. Then, the control switch 12 can be manipulated to control the drive motor 7 to perform soil sampling work.
