[0037] In the embodiment of the utility model, the transmission shaft 23 is used to drive the rotation of the rear wheel axle 211, so that the rear wheel 21 pushes the base 1 to move, and the angle of the transmission shaft 23 is measured and recorded by the angle sensor 241, and then the transmission ratio of the transmission shaft 23 and the rear wheel axle 211, as well as the circumference of the rear wheel 21, is used to measure the moving distance of the base to ensure the accuracy of data measurement.

[0038] In the embodiment of the utility model, the driving motor 22 is a speed-regulating motor. The staff controls the rotation speed of the rear wheel 211 by controlling its rotation speed, so that the device can move slowly when it is about to turn a corner, so as to ensure the accuracy of the device in measuring the distance and reduce its measurement error.

[0039] The rotation angle measuring mechanism 3 is arranged at the rear end of the base 1, and includes: a fixed baffle 31, which is installed between the two handrail frames 11 and located above the folding position thereof, and fixed short shafts 311 are installed at both ends thereof, and the fixed short shaft 311 is connected to the handrail frame 11 through a bearing and a bearing seat, and a rotating short shaft 312 is inserted thereon, and the rotating short shaft 312 is connected to the fixed baffle through a bearing, and a reducer 313 is installed above it, and the output end of the reducer 313 is connected to the rotating short shaft 312; an inverted J-shaped motor seat 32 is installed on one side of the fixed baffle 31, and a motor seat 32 is installed on the outer surface thereof.

[0040] In the embodiment of the utility model, by utilizing the setting of the reducer 313, the reset motor 321 can utilize the deceleration effect of the reducer 313 to drive the rotating short shaft 312 to rotate slowly, so that after the angle adjustment of the device is completed, the support base plate 332 can be accurately reset to ensure the accuracy of its reset. At the same time, the rotating short shaft 312 can utilize the acceleration effect of the reducer 313 to amplify the rotation angle of the input shaft of the reducer 313 according to the transmission ratio, and then utilize the measurement of the angle sensor 322 to accurately calculate the rotation angle of the rotating short shaft 312 to ensure the accuracy of the land contour measurement within the plan.

[0041] In the embodiment of the utility model, by utilizing the setting of the electric push rod 331 and the support base plate 332, the support base plate 332 can be lowered to contact the ground to support the base 1, and the base can be lifted up through the handrail frame 11, so that the angle of the base 1 can be adjusted around the rotating short axis 312, thereby accurately measuring the corners of the land contour to ensure the accuracy of the land measurement.

[0042] In the utility model, a data recorder 324 is installed on the side surface of the inverted J-shaped motor seat 32; the land contour data measured by the device can be collected and recorded, so that the staff can export the land measurement data and perform subsequent terrain mapping and area calculation work.

[0043] In the utility model, the angle sensor 1 241 measures the moving distance by using its rotation angle, the circumference of the rear wheel 21 and the transmission ratio of the bevel gear 231 and the bevel gear 1 212; it can accurately measure the single edge line of the land contour and conveniently record its information.

[0044] In the utility model, the angle sensor 322 measures the angle of the device by using the product of its detected angle value and the transmission ratio of the reducer 313; the reducer 313 can be used to proportionally amplify the rotation angle of the rotating short shaft 312, thereby improving the accuracy of the device rotation angle measurement, reducing measurement errors, and ensuring the accuracy of terrain drawing and area calculation.

[0045] In the utility model, after the electric push rod 331 is extended, the support base plate 332 is in contact with the ground, and then the staff presses the handrail frame 11 to make the base 1 tilt up, and then adjust the angle of the forward direction of the base 1; it is convenient for the staff to adjust the angle of the device during the measurement process.

[0046] When the utility model is used specifically, the staff can sprinkle lime lines on the planned land contour in advance to mark it, and then the staff can select a corner as the starting point and move the base 1 there, while aligning the center of the supporting bottom plate 332 with the center of the corner, and then align the moving direction of the base 1 with one of the lime marking lines;

[0047] Then the staff can measure the outline of the planned land. First, the staff starts working by controlling the driving motor 22. The driving motor 22 rotates the transmission shaft 23 by meshing the driving bevel gear 221 with the driven bevel gear 232. The transmission shaft 23 drives the angle sensor 1 241 to work by using the shaft sleeve 242. At the same time, the bevel gear 231 meshes with the bevel gear 1 212 to drive the rear wheel shaft 211 to rotate, and the rear wheel 21 rotates to drive the base 1 to move along the lime mark line.

[0048] According to the actual situation, when the current straight line marked by lime is about to be completed, the staff controls the rotation speed of the driving motor 22 to reduce so that the base 1 moves slowly, and observes the position of the supporting bottom plate 332 and the end point of the straight line marked by lime. When the supporting bottom plate 332 is aligned with the straight line marked by lime, the driving motor 22 is controlled to stop working. At the same time, the data recorder at this time records the rotation angle of the angle sensor 241, and calculates the current moving distance of the base 1 according to the transmission ratio of the transmission shaft 23 and the rear wheel shaft 211, and the circumference of the rear wheel 21, and records the relevant information;

[0049] Then the staff controls the electric push rod 331 to push the support base plate 332 down and contact the ground, so that the positioning cone 333 is inserted into the soil to fix the support base plate 332. Then the staff presses the handrail frame 11 so that the handrail frame 11 is supported by the fixed short shaft 311, so that the handrail frame 11 drives the base 1 to tilt up through the fixed short shaft 311, thereby separating the front wheel 14 and the rear wheel 21 from the ground.

[0050] Subsequently, the staff rotates the handrail frame 11 to drive the base 1 to rotate around the rotating short shaft 312, and then when the reducer 313 rotates with the handrail frame 11, the reducer 313 and the rotating short shaft 312 rotate relative to each other, and utilizes the transmission of the reducer 313 to rotate its input shaft and amplify its rotation angle, and then utilizes the transmission of the synchronous gear 323 to rotate the angle sensor 2 322 by a certain angle. When the base 1 is aligned with the subsequent lime mark straight line, the handrail frame 11 is slowly lifted up at this time to place the base 1 back on the ground, and at the same time, the data recorder 324 records the angle currently recorded by the angle sensor 2 322, and calculates the rotation angle of the base 1 relative to the rotating short shaft 312 according to the transmission ratio, and records and stores it;

[0051] Then, the electric push rod 331 can be controlled to retract, so that the support base plate 332 rises and separates from the ground, and then the reset motor 321 is controlled to work, and the measurement value of the angle sensor 322 is reset to zero through the measurement of the angle sensor 322, so that the support base plate 332 and the base 1 are parallel again;

[0052] By repeating the above operations, the staff divides the planned land contour into several straight line segments and records the length of each straight line segment and the angle between the adjacent straight line segments, thereby recording the contour data of the entire land;

[0053] When the measurement is completed, the staff can copy the data recorded in the data recorder 324, and use the data to draw the current land topography, and measure the area of ​​the drawn topography to obtain an accurate land area result.

[0054] When the device is implemented, the staff can set a marking arrow at the front center of the upper surface of the base 1, so that the base 1 can be quickly aligned with the lime marking line when the angle is adjusted.
