Description

Technical Field

[0001] The utility model relates to the technical field of land measurement, and more specifically to a measuring device for comprehensive land improvement. Background Art

[0002] Land surveying is the work of measuring and mapping the quantity, distribution and topography of various types of land using surveying and remote sensing technology. It includes topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, and investigation of reserve resources such as barren hills and wastelands. Currently, RTK is a more common land surveying device, which is based on differential GPS technology to obtain the coordinates of the measuring points for land surveying.

[0003] RTK is usually equipped with an additional support tripod to support the RTK during measurement. However, when working in the field and other scenarios where it is inconvenient to carry the support tripod, the staff will generally choose to remove the support tripod. At this time, the staff can only manually center the RTK. If the soil at the measurement location is relatively loose, the staff may need to adjust for a long time to center the RTK without additional support. Therefore, it is urgent to design a measurement device for comprehensive land improvement to solve the above problems. Utility Model Content

[0005] The utility model provides the following technical solutions: a measuring device for comprehensive land improvement, including a bottom cone, a support assembly, a sleeve assembly, a push assembly, a fixture, a data display device, and a receiver. The support assembly is fixedly mounted on the top of the bottom cone, the sleeve assembly is fixedly mounted on the top of the support assembly, the push assembly is slidably plugged into the sleeve assembly, the push assembly is connected to the support assembly, and can push the support assembly to move;

[0006] The support assembly includes a first fixing plate, a fixing rod, a second fixing plate, and two mounting rings. The second fixing plate is fixedly mounted on the top of the bottom cone, the fixing rod is fixedly mounted on the top of the second fixing plate, the first fixing plate is fixedly mounted on the top of the fixing rod, one mounting ring is fixedly mounted on the top of the second fixing plate, and the other mounting ring is slidably sleeved on the outer wall of the fixing rod;

[0007] The fixture is arranged on the outer wall of the pushing component, the data display device is arranged in the fixture, a level bubble is arranged on the top of the fixture for centering the sleeve component and the pushing component, and a receiver is arranged on the top of the pushing component for receiving GPS signals.

[0008] Furthermore, the support assembly also includes four support parts, and the four support parts are equidistantly distributed between the two mounting rings.

[0009] Furthermore, the support portion includes two connecting rods, a bracket, and a support plate. The two connecting rods are rotatably installed in two mounting rings respectively, the bracket is rotatably installed between the two connecting rods, and the support plate is fixedly installed at one end of the bracket.

[0010] Furthermore, the sleeve assembly includes a hollow cylinder, which is fixedly mounted on the top of the first fixed plate, and the pushing assembly includes a telescopic rod, which is slidably inserted in the hollow cylinder.

[0011] Furthermore, the pushing assembly also includes a circular groove, a locking block, and a spring.

[0014] Technical effects and advantages of the utility model:

[0015] When the utility model is in use, the bottom cone is placed on the ground, the level bubble is centered, and the receiver is started. At this time, the receiver will receive the GPS signal and obtain the current coordinates, which will then be displayed through the data display device for the staff to read. If loose soil is encountered, which makes it inconvenient to align the center, the locking block is pressed inwards to compress the spring and press the locking block into the circular groove to unlock the telescopic rod. At this time, the telescopic rod is slid downward to drive the four push rods to slide downward, and the mounting ring that is slidably sleeved on the outer wall of the fixed rod is pushed downward to push the four connecting rods connected thereto to rotate downward, thereby pushing the four brackets and the four support plates to slide outwards and slide downward at the same time. When the telescopic rod slides downward and drives the locking block to slide to the second locking hole, the spring will be released and push the locking block to engage into the second locking hole, so as to lock the position of the telescopic rod and the four support plates. At this time, the four support plates can provide additional support for the telescopic rod, which is convenient for aligning the hollow core tube, the telescopic rod and the receiver in the loose soil, thereby improving its practicality.
