[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0023] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0024] Refer to Figures 1-4 , a soil-taking device for highway engineering, including an installation frame 1. A support frame 2 is correspondingly arranged on the surface of the installation frame 1. The bottom of the support frame 2 is rotatably connected to a rotating rod 3 through a bearing. A placement groove 4 is formed on the surface of the rotating rod 3. An elastic member 5 is fixedly connected to the inner wall of the placement groove 4. The end of the elastic member 5 is fixedly connected to a piston block 6. A protruding block 7 is fixedly connected to the side surface of the piston block 6. A spiral cutter 8 is movably connected to the surface of the rotating rod 3. A jack 9 is formed on the surface of the spiral cutter 8. The inner wall of the jack 9 is movably connected to the protruding block 7.
[0025] In the present utility model, when a certain part of the spiral cutter 8 is damaged, the staff can reach into the jack 9 in the spiral cutter 8 with their hands, so that the fingers can press on the protruding block 7, and at the same time, the protruding block 7 is pushed to move the piston block 6 to the innermost part of the placement groove 4, and synchronously, the piston block 6 is pushed to move the elastic member 5 to the innermost part of the placement groove 4. At this time, the staff can pull the spiral cutter 8 to move downward in the rotating rod 3, so that the jack 9 and the protruding block 7 are misaligned. However, it is convenient for the staff to quickly replace the damaged spiral cutter 8, avoiding the increase in economic cost caused by traditional overall replacement.
[0026] The elastic member 5 in this solution can be set as a reset spring or an elastic sheet or other elastic parts.
[0027] In this solution, the elastic member 5 is affected by hand extrusion. When the hand is released, it will not quickly reset, and its reset speed is relatively slow, so it does not affect the staff to disassemble or install the spiral cutter 8.
[0028] Refer to Figure 3 , a limiting block 10 is fixedly connected to the inner wall of the placement groove 4, and the limiting block 10 is located on one side surface of the piston block 6 and the protruding block 7.
[0029] In the present utility model, through the provision of the rotating rod 3, the piston block 6 can be limited, preventing the elastic member 5 from being affected by the elastic force and causing the piston block 6 and the protruding block 7 to disengage from the placement groove 4, thus affecting normal use.
[0030] Refer to Figure 4 , the inner wall of the jack 9 is threadedly connected with a threaded cover 11, and the inside of the threaded cover 11 is hollow.
[0031] In the present utility model, through the provision of the threaded cover 11, the jack 9 can be shielded, preventing the soil from entering the jack 9 during the soil extraction process and pushing the protruding block 7 towards the innermost part of the placement groove 4, resulting in the detachment of the spiral cutter 8 and making it unusable.
[0032] Refer to Figure 4 , a storage groove 12 is formed on the side surface of the threaded cover 11, and a pull handle 13 is rotatably connected to the inside of the storage groove 12 through a rotating shaft.
[0033] In the present utility model, through the provision of the pull handle 13, the contact area of the staff's hand can be increased, facilitating the staff to better drive the threaded cover 11 to rotate.
[0034] Refer to Figure 4 , a finger groove 14 is formed on the side surface of the threaded cover 11, and the surface of the finger groove 14 communicates with the storage groove 12.
[0035] In the present utility model, through the provision of the finger groove 14, it is convenient for the subsequent staff to take out the pull handle 13 from the storage groove 12, laying a foundation for the subsequent rotation of the threaded cover 11.
[0036] Refer to Figure 1 , multiple fixing blocks 15 are respectively fixedly connected to the surface of the mounting frame 1. A lead screw 16 is rotatably connected between a group of fixing blocks 15 through a bearing. A moving block 17 is threadedly connected to the surface of the lead screw 16, and the surface of the moving block 17 is fixedly connected to the support frame 2.
[0037] In the present utility model, when it is necessary to extract soil at different depths, the staff can drive the lead screw 16 to rotate through the motor, and at the same time, make the lead screw 16 drive the moving block 17 to move upward or downward. Synchronously, make the moving block 17 drive the support frame 2 and the rotating rod 3 to move upward or downward, and then make the rotating rod 3 drive the spiral cutter 8 to move upward or downward, so as to facilitate the staff to extract soil at different depths, and thus effectively improve the practicability of the soil extraction device.
[0038] Refer to Figure 1 , a guide rod 18 is fixedly connected between the other two groups of fixing blocks 15. A guide block 19 is slidably connected to the surface of the guide rod 18, and the surface of the guide block 19 is fixedly connected to the support frame 2.
[0039] In the present utility model, through the arrangement of the guide rod 18 and the guide block 19, the support frame 2 can be positioned to prevent the support frame 2 from tipping over when the lead screw 16 drives the moving block 17 and the support frame 2 to move, so that it cannot be used normally.
[0040] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
