Description

Technical Field

[0001] The present invention relates to the technical field of measuring instruments, and in particular to a measuring instrument for land resource management. Background Art

[0002] Land resources are key resources in my country, and their management requires advance measurement. The current total station integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement functions. All measurement work at the survey station can be completed by setting up the instrument once.

[0003] However, in addition to total station measurement, soil properties also need to be tested. In the prior art, land measurement and soil property testing are performed in separate steps, which reduces the efficiency of measurement and testing. Summary of the Invention

[0004] The present invention proposes a measuring instrument for land resource management. By integrating soil detection into a total station and using clever structural design, the quantitative values ​​of points and detection information of soil properties can be obtained at one time, thereby improving the efficiency of measurement and detection. At the same time, points can also be marked in a linked manner.

[0005] To this end, the present invention provides a measuring instrument for land resource management, including a box body, a frame body hingedly connected to the lower part of the box body, an instrument body provided on the upper part of the box body, a hollow mounting column provided in the middle position of the lower part of the box body, a driving mechanism provided between the mounting column and the frame, the driving mechanism driving a soil detection mechanism connected and slidably arranged on the mounting column, and the soil detection mechanism is connected to a marking mechanism rotatably arranged on the mounting column.

[0006] By adopting the above technical solution: the box is the installation carrier, the upper part of which is provided with the instrument body for measuring horizontal angle, vertical angle, distance (slant distance, horizontal distance), height difference, etc., the processor, etc. is installed inside, the frame is used to support the box during measurement, and the mounting column in the middle of the box is used to install the driving mechanism. During the process of the frame being expanded, the driving mechanism can drive the soil detection mechanism to move and detect the composition and properties of the soil. At the same time, the soil detection mechanism can drive the marking mechanism to move in a linkage manner during the movement process to mark the point, thereby improving the measurement efficiency and enriching the function of the measuring instrument.

[0007] Optionally, the frame includes three support rods hinged at the lower part of the box body, and the driving mechanism includes a driving block slidably connected to the mounting column, the side of the driving block is rotatably connected to one end of the driving rod, and the other end of the driving rod is rotatably connected to the support rod, and a push rod is provided at the lower end of the driving block, and the push rod drives the soil detection mechanism.

[0008] By adopting the above technical solution: when the three support rods are simultaneously extended, the driving block can be driven to slide on the mounting column through the driving rod, so that the soil detection mechanism can be driven to operate through the transmission of the push rod.

[0009] Optionally, the driving rod is provided with three hinged ends respectively hinged to three support rods, and one end of the driving rod connected to the support rod is lower than the end connected to the driving block.

[0010] By adopting the above technical solution: when the support rod is extended, the driving block can be driven by the driving rod to move downward along the mounting column, thereby driving the soil detection mechanism to move downward through the push rod. In the opposite process, when the support rod is retracted, the driving block can drive the soil detection mechanism to move upward through the push rod.

[0011] Optionally, a positioning slide rail is provided on the mounting column, and the soil detection mechanism includes a mounting plate slidably set on the mounting column through the positioning slide rail, the upper part of the mounting plate is connected to the push rod, and the lower part of the mounting plate is connected to the push plate, and a plurality of needle sensors are provided on the push plate, and the plurality of needle sensors are connected to the processor set in the box through signal lines arranged in the mounting column.

[0012] By adopting the above technical solution: the mounting plate serves as a mounting carrier, the upper part of which is connected to the push rod and can be moved up and down by the driving block. When the support rod is unfolded, the push rod drives the mounting plate to move downward, and the needle sensor at its lower part can be inserted into the soil to detect the soil composition, and the detection information can be transmitted to the processor for data processing.

[0013] Optionally, a linkage member is provided on the inner side of the push plate, and the linkage member drives the connection marking mechanism.

[0014] By adopting the above technical solution: when the point value measurement and soil composition detection are completed, the support rod is retracted, the driving block moves up and drives the mounting plate to move up through the push rod.

[0024] 1. The frame is used to support the box during measurement. The mounting column in the middle of the box is used to install the driving mechanism. When the frame is extended, the driving mechanism can drive the soil detection mechanism to detect the composition and properties of the soil.

This improves the measurement efficiency and enriches the functions of the measuring instrument.

[0025] 2. When the support rod is extended, the driving rod can drive the driving block to move downward along the mounting column, thereby driving the soil detection mechanism downward through the push rod to detect the soil composition. The reverse process is when the support rod is retracted, and the driving block can drive the soil detection mechanism upward through the push rod.

[0026] 3. When the point value measurement and soil composition detection are completed, the support rod is retracted, the drive block moves up and drives the mounting plate to move up through the push rod.

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 3 As shown, this embodiment provides a measuring instrument for land resource management, including a box body 100, the lower part of the box body 100 is hinged with a frame body 200, the upper part of the box body 100 is provided with an instrument body 300, and a hollow mounting column 400 is provided in the middle position of the lower part of the box body 100. A driving mechanism 500 is provided between the mounting column 400 and the frame body 200, and the driving mechanism 500 drives a soil detection mechanism 600 connected and slidably set on the mounting column 400, and the soil detection mechanism 600 is connected to a marking mechanism 700 rotatably set on the mounting column 400.

[0034] The basic principle of this embodiment is as follows: the box 100 is an installation carrier, and an instrument body 300 is provided on its upper part for measuring horizontal angles, vertical angles, distances (slant distances, horizontal distances), height differences, etc., and a processor, etc. is installed inside. The frame 200 is used to support the box 100 during measurement, and the mounting column 400 in the middle of the box 100 is used to install the driving mechanism 500. When the frame 200 is extended, the driving mechanism 500 can drive the soil detection mechanism 600 to operate to detect the composition and properties of the soil. At the same time, the soil detection mechanism 600 can drive the marking mechanism 700 to operate in a linkage manner during the operation process to mark the points, thereby improving the measurement efficiency and enriching the functions of the measuring instrument.

[0035] The frame 200 in this embodiment includes three support rods hinged at the lower part of the box body 100, and the driving mechanism 500 includes a driving block 510 slidably connected to the mounting column 400. The side of the driving block 510 is rotatably connected to one end of the driving rod 520, and the other end of the driving rod 520 is rotatably connected to the support rod. The lower end of the driving block 510 is provided with a push rod 530, and the push rod 530 drives the soil detection mechanism 600.

[0036] The operating principle is as follows: when the three support rods are simultaneously unfolded, the driving rod 520 can drive the driving block 510 to slide on the mounting column 400, thereby driving the soil detection mechanism 600 to operate through the transmission of the push rod 530.

[0037] Of course, in this embodiment, the driving rod 520 is provided with three hingedly connected to the three support rods respectively, and the end of the driving rod 520 connected to the support rod is lower than the end connected to the driving block 510.

[0038] In this way, when the support rod is unfolded, the driving block 510 can be driven to move downward along the mounting column 400 through the driving rod 520, thereby driving the soil detection mechanism 600 to move downward through the push rod 530. In the opposite process, when the support rod is retracted, the driving block 510 can drive the soil detection mechanism 600 to move upward through the push rod 530.

[0039] A positioning rail 410 is provided on the mounting column 400. The soil detection mechanism 600 includes a mounting plate 610 that is slidably set on the mounting column 400 through the positioning rail 410. The upper part of the mounting plate 610 is connected to the push rod 530, and the lower part of the mounting plate 610 is connected to a push plate 640. The push plate 640 is provided with a plurality of needle sensors 620. The plurality of needle sensors 620 are communicatively connected to the processor set in the box 100 via a signal line set in the mounting column 400.

[0040] The mounting plate 610 in this embodiment serves as a mounting carrier, and its upper portion is connected to the push rod 530 and can be moved up and down by the driving block 510. When the support rod is unfolded, the push rod 530 drives the mounting plate 610 to move downward, and the needle sensor 620 on the lower push plate 640 can be inserted into the soil to detect soil composition, and the detection information can be transmitted to the processor for data processing, such as soil moisture, pH value and other information.

[0041] In order to enable the marking mechanism 700 to operate when the mounting plate 610 moves upward after the measurement is completed, a linkage member is provided on the inner side of the push plate 640 in this embodiment, and the linkage member drives the connection marking mechanism 700.

[0042] The basic principle is: when the point value measurement and soil composition detection are completed, the support rod is retracted, the driving block 510 moves up and drives the mounting plate 610 to move up through the push rod 530. At this time, the mounting plate 610 drives the push plate 640 to move up and drives the marking mechanism 700 to move through the linkage to mark the point.

[0043] The linkage part includes a slide rod 630 arranged on the inner side of the push plate 640, and the marking mechanism 700 includes a rotating body 710 rotatably connected to the mounting column 400. The outer side of the rotating body 710 is provided with a slide groove 720 that cooperates with the slide rod 630. A marking component is provided inside the rotating body 710. The rotating body 710 is cylindrical, and the slide groove 720 is an oblique groove, which forms an angle with the center line of the rotating body 710.

[0044] In this way, when the push plate 640 moves upward, the slide rod 630 is in the slide groove 720. Since the slide rod 630 can only move vertically upward, at this time, because the slide groove 720 and the center line of the rotating body 710 have an angle, the rotating body 710 is driven to rotate around the mounting column 400. At this time, the marking component can be controlled to rotate and mark the point.

[0045] The marking assembly includes a marking liquid chamber 730 disposed inside the rotating body 710 . The lower portion of the marking liquid chamber 730 is connected to a liquid pipe 750 via a solenoid valve 740 . The solenoid valve 740 is electrically connected to the processor via a wire disposed in the mounting column 400 .

[0046] The marking liquid cavity 730 can store colored marking liquid. When the rotating body 710 rotates, the electromagnetic valve 740 is controlled to open, and the marking liquid can leak out through the liquid tube 750, thereby marking the point.

[0047] In this embodiment, the upper and lower portions of the positioning rail 410 are provided with limit blocks 420, which can limit the range of vertical movement of the driving block 510. A display screen 800 and a control button 900 are provided on the outside of the housing 100. The display screen 800 and the control button 900 are communicatively connected to the processor. A power supply is provided inside the housing 100, which is electrically connected to the processor and the display screen 800 to provide power. This allows the soil composition to be displayed on the display screen 800. After the measurement is completed, the control button 900 and the processor can be used to control the solenoid valve 740 to open and mark the point.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
