Description

Technical Field

[0001] This utility model relates to the field of land planning technology, specifically to an improved device for measuring soil layer thickness in land planning. Background Technology

[0002] In the process of land planning, soil layer thickness is a very critical technical indicator. In order to measure soil layer thickness, some measurement technologies or equipment have emerged.

[0003] A soil thickness measuring device for land planning, disclosed in Chinese Patent Publication No. CN 219624656 U, features a hollow base with through holes at the top and bottom center. A lifting rod passes through the through hole at the top and bottom of the base, allowing it to move up and down within the base. A vertical toothed strip is provided on the lower side of the lifting rod, meshing with a driven gear, which in turn meshes with a driving gear. The driven gear has a larger diameter than the driving gear. A first fixed rod is fixedly connected at one end to the base and rotatably connected to the driven gear shaft at the other end. A second fixed rod passes through the base and is fixedly connected to a hand crank handle at one end, and to the driving gear shaft at the other end. The bottom of the lifting rod is movably connected to a soil sampling cylinder, and the bottom of the soil sampling cylinder is movably connected to a soil breaking component. This device solves the problem of excessive effort required when using existing soil thickness measuring tools.

[0004] It should be noted that soil thickness refers to the thickness in the vertical direction. Therefore, when measuring soil thickness, the device needs to be placed horizontally. However, some soil surfaces are not horizontal, so the measuring device needs to be leveled to ensure the accuracy of the measurement. However, the soil thickness measuring device for land planning mentioned above does not have a leveling function. When the ground is uneven, it is difficult to ensure the horizontal state of the device, which affects the accuracy of the measurement. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes an improved device for measuring soil layer thickness in land planning, in order to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An improved device for measuring soil layer thickness in land planning includes a base, a horizontal adjustment mechanism fixedly connected to the top of the base, and a measuring component disposed on the horizontal adjustment mechanism;

[0008] The leveling mechanism includes a first support, a first rotating shaft rotatably connected inside the first support, a first worm gear fixedly connected to the right side of the first rotating shaft through the first support, a first bracket mounted on the right side of the first support, a first worm gear rotatably connected inside the first bracket, a first adjusting rod fixedly connected to the first rotating shaft, a first spirit level fixedly connected to the right side of the first adjusting rod, a second support fixedly connected to the top of the first adjusting rod, a second rotating shaft rotatably connected inside the second support, a second worm gear fixedly connected to the back side of the second rotating shaft through the second support, a second bracket fixedly connected to the back side of the second support, a second worm gear rotatably connected inside the second bracket, a measuring frame fixedly connected to the front side of the second rotating shaft through the second support, and a second spirit level mounted on the top of the measuring frame.

[0009] Preferably, the first worm meshes with the first worm wheel, and a first handwheel is fixedly connected to the top of the first worm.

[0010] Preferably, the second worm meshes with the second worm wheel, and a second handwheel is fixedly connected to the top of the second worm.

[0011] Preferably, the bottom of the first support is fixedly connected to the base, and the bottom of the base is provided with four fixed cones.

[0012] Preferably, the measuring component includes a conical rod, the interior of which is hollow, a measuring rod is inserted into the interior of the conical rod, and a rotating handle is fixedly connected to the surface of the conical rod.

[0013] Preferably, the measuring frame has a threaded hole, and the tapered rod is threaded into the threaded hole.

[0014] Preferably, the surface of the measuring rod is provided with scale lines.

[0015] Compared with existing technologies, the beneficial effects of this utility model's improved device for measuring soil layer thickness in land planning are:

[0016] First, the first handwheel drives the first worm gear to rotate, achieving horizontal adjustment. The second handwheel drives the second worm gear to rotate, achieving vertical adjustment. The two adjustment axes are designed to be perpendicular and orthogonal, which can independently compensate for the tilt of the terrain in two directions. The worm gear transmission has a self-locking characteristic, and there is no backlash error after adjustment, ensuring that the measuring frame can maintain an absolutely horizontal state in complex terrain, significantly improving measurement accuracy.

[0017] Secondly, the cone rod and the measuring frame are connected by a thread, which can be quickly assembled and disassembled by rotating the handle. The threaded connection structure ensures that the insertion direction of the cone rod is perpendicular to the horizontal plane of the measuring frame, avoiding soil compression errors caused by tilting. The hollow cone rod is inserted with a graduated measuring rod. After being pulled out, the measuring rod automatically aligns with the soil surface due to gravity, and the scale value can be read directly. The operation is simple and the data is intuitive and reliable. Attached Figure Description

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] Please refer to the improved device for measuring soil layer thickness in land planning under this specific embodiment. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a base 1, a horizontal adjustment mechanism is fixedly connected to the top of the base 1, and a measuring component is provided on the horizontal adjustment mechanism;

[0025] The leveling mechanism includes a first support 2, a first rotating shaft 3 rotatably connected inside the first support 2, a first worm gear 4 fixedly connected to the right side of the first rotating shaft 3 through the first support 2, a first bracket mounted on the right side of the first support 2, a first worm 5 rotatably connected inside the first bracket, a first adjusting rod 6 fixedly connected to the first rotating shaft 3, a first spirit level 7 fixedly connected to the right side of the first adjusting rod 6, a second support 8 fixedly connected to the top of the first adjusting rod 6, a second rotating shaft 9 rotatably connected inside the second support 8, a second worm gear 10 fixedly connected to the back of the second rotating shaft 9 through the second support 8, a second bracket fixedly connected to the back of the second support 8, a second worm 11 rotatably connected to the inside of the second bracket, a measuring frame 12 fixedly connected to the front of the second rotating shaft 9 through the second support 8, and a second spirit level 13 mounted on the top of the measuring frame 12.

[0026] Through the above technical solution, the first support 2 provides a foundation for the support and rotation of the first rotating shaft 3. The first rotating shaft 3 can rotate within the first support 2, and its right side is connected to the first worm gear 4. The first bracket is used to support the first worm 5. The first worm 5 and the first worm gear 4 mesh with each other. When the first worm 5 is rotated, due to the transmission characteristics of the worm gear, the first worm gear 4 will be driven to rotate, thereby causing the first rotating shaft 3 to rotate. The first adjusting rod 6 is fixed on the first rotating shaft 3, so when the first rotating shaft 3 rotates, it will drive the first adjusting rod 6 to rotate. The first level 7 is used to determine whether the first adjusting rod 6 is in a horizontal state. The second support 8 is fixed on the first adjusting rod 6, providing space for the support and rotation of the second rotating shaft 9. The back of the second rotating shaft 9 is connected to the second worm gear 10. When the second worm 11 is rotated, the second worm gear 10 will be driven to rotate, thereby causing the second rotating shaft 9 to rotate. The measuring frame 12 is fixed on the front of the second rotating shaft 9, so when the second rotating shaft 9 rotates, it will drive the measuring frame 12 to rotate. The second level 13 is used to determine whether the measuring frame 12 is in a horizontal state.

[0027] The first worm 5 meshes with the first worm wheel 4, and the top of the first worm 5 is fixedly connected to the first handwheel 14.

[0028] Through the above technical solution, the worm gear transmission has the characteristics of self-locking and speed reduction and torque increase. By rotating the first handwheel 14, the first worm 5 can be easily rotated, thereby driving the first worm wheel 4 and the first rotating shaft 3 to rotate, realizing the fine adjustment of the angle of the first adjusting rod 6, so that the first level bubble 7 reaches the horizontal state, thereby adjusting the levelness of the device in one direction.

[0029] The second worm 11 meshes with the second worm wheel 10, and the top of the second worm 11 is fixedly connected to the second handwheel 15.

[0030] The above technical solution also utilizes the characteristics of worm gear transmission. By rotating the second handwheel 15, the second worm 11 can be rotated, which in turn drives the second worm wheel 10 and the second rotating shaft 9 to rotate. This allows for fine adjustment of the angle of the measuring frame 12, ensuring that the second bubble level 13 is horizontal. Further adjustments can be made to the levelness of the device in another direction to ensure that the measuring frame 12 is in a horizontal position.

[0031] The bottom of the first support 2 is fixedly connected to the base 1, and the bottom of the base 1 is provided with four fixed cones 16.

[0032] Through the above technical solution, the first support 2 is fixed on the base 1, the base 1 provides support for the entire device, and the four fixed cones 16 can be inserted into the ground to fix the device in the measurement position, prevent the device from moving during the measurement process, and ensure the stability of the measurement.

[0033] The measuring assembly includes a cone rod 17, which is hollow inside. A measuring rod 18 is inserted into the inside of the cone rod 17, and a rotating handle 19 is fixedly connected to the surface of the cone rod 17.

[0034] With the above technical solution, the cone rod 17 is hollow inside to accommodate the measuring rod 18, and the rotating handle 19 makes it convenient for the operator to rotate the cone rod 17.

[0035] The measuring frame 12 has a threaded hole, and the tapered rod 17 is threaded into the threaded hole.

[0036] Through the above technical solution, the tapered rod 17 is connected to the threaded hole on the measuring frame 12 by a thread. When the tapered rod 17 is rotated, according to the principle of thread transmission, the tapered rod 17 will move up and down along the threaded hole.

[0037] The surface of the measuring rod 18 is provided with scale lines 20.

[0038] Through the above technical solution, the scale line 20 is used to read the depth of the measuring rod 18 inserted into the soil layer, thereby measuring the thickness of the soil layer.

[0039] Its working principle is as follows: Insert the four fixed cones at the bottom of the base 1 into the soil to fix the device in the measurement position. Turn the first handwheel 14 to drive the first worm gear 5 to rotate, which in turn drives the first rotating shaft 3 and the first adjusting rod 6 to rotate through the first worm wheel 4. Observe the first level bubble 7 and make the first adjusting rod 6 horizontal in one direction. Turn the second handwheel 15 to drive the second worm gear 11 to rotate, which in turn drives the second rotating shaft 9 and the measuring frame 12 to rotate through the second worm wheel 10. Observe the second level bubble 13 and make the measuring frame 12 horizontal in another direction. Ensure that the measuring frame is in a horizontal state. Hold the rotating handle 19 to rotate the cone rod 17. Since the cone rod 17 is threadedly connected to the measuring frame 12, the cone rod 17 will move downward and insert into the soil layer. When the cone rod 17 is inserted to a suitable depth, read the value displayed on the scale line 20 on the surface of the measuring rod 18. This value is the thickness of the soil layer.

[0040] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
