Description

Technical Field

[0001] The present invention relates to the technical field of land surveying, and in particular to a land surveying device for land management. Background Art

[0002] Land surveying devices used for land management usually integrate advanced surveying technologies (such as GPS, GIS, laser ranging, drones, etc.) to perform accurate land surveying, positioning, and data analysis. The following are several common designs and applications of surveying devices or systems used for land management: 1. Global Positioning System (GPS) Surveying instrument, Purpose: Widely used for precise positioning of land and boundary measurement, especially in large-scale land management. By receiving satellite signals, the precise location of the measurement point is determined. High-precision GPS equipment (such as RTK GPS) can provide centimeter-level measurement accuracy.

[0003] 2. A roller distance meter (also called a roller distance meter or roller distance meter) is a tool that measures the distance on the ground or surface by rolling a wheel. It is often used in outdoor environments such as construction sites, road construction, site measurement, etc. It is widely used to measure short distances because of its simplicity, intuitiveness and portability.

[0004] During the use of the roller rangefinder, since there are often stones of various sizes on the ground to be measured, the existing roller rangefinder is not convenient for handling the stones, resulting in the roller rangefinder passing directly over the stones or needing to bypass the stones, which will affect the rotation of the wheel and cause inaccurate measurement.

[0020] like Figure 1-Figure 8 A land surveying device for land management shown in the figure comprises a fixed frame 1, a distance measuring roller 2 is mounted on the fixed frame 1, a push handle 3 is rotatably connected to the fixed frame 1, auxiliary wheel frames 4 are rotatably connected to both sides of the bottom of the fixed frame 1, an equipment frame 5 is connected and fixedly provided on the fixed frame 1, a stone pushing mechanism 6 is rotatably provided on the equipment frame 5, an air guide hood 7 is connected and fixedly provided inside the equipment frame 5, and a transmission mechanism 8 is slidably provided through the equipment frame 5.

[0021] like Figure 3As shown, the bottom end of the push handle 3 is arranged in a U-shaped structure, and the two sides of the bottom end of the push handle 3 are connected and fixed with a rotating shaft 301, and the rotating shaft 301 is rotatably connected with the fixed frame 1. The end of the rotating shaft 301 located in the fixed frame 1 is connected and fixed with an arc-shaped rack 302, and a positioning rod 303 is slidably arranged in the rotating shaft 301. The end of the positioning rod 303 located in the rotating shaft 301 is connected and fixed with a spring A304, and the other end of the spring A304 is connected and fixed with the inner wall of the rotating shaft 301. The finger is inserted into the positioning hole 101, and the positioning rod 303 is pushed out of the positioning hole 101, so that the push handle 3 can rotate, and then under the action of the spring A304, the positioning rod 303 is inserted into another positioning hole 101 to position the push handle 3.

[0022] like Figure 4 As shown, two positioning holes 101 are formed through the inner walls of both sides of the fixing frame 1 , and the positioning holes 101 are movably connected with the positioning rods 303 .

[0023] like Figure 4 As shown, one end of the auxiliary wheel frame 4 is rotatably connected with an auxiliary wheel 401, one end of the auxiliary wheel frame 4 is connected and fixed with a pin shaft, the other end of the pin shaft is rotatably connected with the fixed frame 1, and one end of the pin shaft located in the fixed frame 1 is connected and fixed with an adjusting wheel 402, and the adjusting wheel 402 is meshed and driven with the arc-shaped rack 302. When the push handle 3 rotates, the arc-shaped rack 302 connected to the rotating shaft 301 will be driven to rotate, so that the arc-shaped rack 302 drives the auxiliary wheel frame 4 connected to the adjusting wheel 402 to rotate and lower, so that the auxiliary wheel 401 contacts the ground to provide auxiliary support for the device.

[0024] like Figure 5 As shown, a motor 501 is fixedly installed on the equipment frame 5, and a toggle rod 502 is fixedly connected to the output end of the motor 501, and a transmission pressure rod 503 is fixedly connected to the toggle rod 502. The motor 501 drives the toggle rod 502 to rotate, so that the other end of the toggle rod 502 slides in the slide groove 603, thereby driving the swing frame 601 connected to the lever frame 602 to swing back and forth.

[0025] like Figure 6As shown, the stone pushing mechanism 6 includes a swing frame 601, one end of which is rotatably connected to the equipment frame 5, a lever frame 602 is fixedly connected to the top of the swing frame 601, a slide groove 603 is provided at the top of the lever frame 602, the inner wall of the slide groove 603 is slidably matched with the outer wall of the toggle rod 502, a moving block 604 is slidably matched on the swing frame 601, a tension spring 605 is fixedly connected to the moving block 604, and the other end of the tension spring 605 is fixedly connected to the inner wall of the swing frame 601. The moving block 604 connected to the tension spring 605 enables the stone-pushing plate 606 to automatically move up to unload the force when it contacts the stone that cannot be pushed, thereby avoiding overloading of the device. The swing frame 601 swings back and forth, causing the stone-pushing plate 606 to swing back and forth to push away the stones on the ground. When the stone-pushing plate 606 contacts a stone that cannot be pushed away, the moving block 604 connected to the tension spring 605 moves up, thereby driving the stone-pushing plate 606 to move up to unload the force.

[0026] The moving block 604 is rotatably connected with a stone-moving plate 606, one end of which is connected and fixed with a worm wheel 607, and the moving block 604 is rotatably connected with a universal joint 608, one end of which is connected and fixed with a worm 609, which is meshed and driven with the worm wheel 607, and the other end of the universal joint 608 is connected and fixed with a handle. The worm 609 can realize the retraction and release of the stone-moving plate 606, which is convenient for carrying the device. The universal joint 608 is rotated, so that the universal joint 608 drives the connected worm 609 to rotate, so that the worm 609 drives the stone-moving plate 606 connected with the worm wheel 607 to rotate and lower.

[0027] like Figure 7 As shown, a fan blade 701 is rotatably connected in the air guide cover 7, one end of the fan blade 701 passes through the air guide cover 7 and the inner wall of the equipment frame 5 to extend to the outside and is connected and fixedly provided with a driven wheel 702, and a jet pipe 703 is connected and fixedly provided on one side of the air guide cover 7, and the other end of the jet pipe 703 passes through the bottom end of the equipment frame 5 to extend to the outside. The transmission wheel 805 drives the driven wheel 702 to rotate, thereby driving the fan blade 701 connected to the driven wheel 702 to rotate, sucking the external air into the air guide cover 7, and spraying it out through the jet pipe 703 to blow away the sand on the ground.

[0028] like Figure 8As shown, the transmission mechanism 8 includes a sliding frame 801, and the sliding frame 801 is slidably matched with the equipment frame 5. The bottom end of the upper side of the sliding frame 801 is connected and fixed with a spring B802, and the other end of the spring B802 is connected and fixed with the equipment frame 5. The top surface of the upper side of the sliding frame 801 is in sliding contact with the transmission pressure rod 503. The bottom end of the sliding frame 801 is connected and fixed with a rack 803, and one side of the rack 803 is meshingly provided with a driving wheel 804, and one side of the driving wheel 804 is connected and fixed with a transmission wheel 805. The transmission wheel 805 is rotatably connected with the equipment frame 5 through a pin shaft, and the transmission wheel 805 is meshingly transmitted with the driven wheel 702. When the toggle rod 502 rotates, the connected transmission pressure rod 503 will be driven to rotate, so that the transmission pressure rod 503 can contact and squeeze the sliding frame 801, so that the sliding frame 801 drives the connected rack 803 to move downward, so that the rack 803 drives the driving wheel 804 to rotate, and at this time the driving wheel 804 drives the transmission wheel 805 to rotate.

[0029] Working principle: When it is necessary to measure the land, the distance measuring roller 2 is used for measurement. First, a finger is inserted into the positioning hole 101 to push the positioning rod 303 out of the positioning hole 101 so that the push handle 3 can rotate. Then, under the action of the spring A304, the positioning rod 303 is inserted into another positioning hole 101 to position the push handle 3. When the push handle 3 rotates, the arc-shaped rack 302 connected to the rotating shaft 301 is driven to rotate, so that the arc-shaped rack 302 drives the auxiliary wheel frame 4 connected to the adjusting wheel 402 to rotate and lower, so that the auxiliary wheel 401 contacts the ground to provide auxiliary support for the device. Then, the universal joint 608 is rotated, so that the universal joint 608 drives the connected worm 609 to rotate, so that the worm 609 drives the stone plate 606 connected to the worm wheel 607 to rotate and lower; Then, the distance measuring roller 2 is pushed to move by the push handle 3, so that the distance measuring roller 2 rolls to measure the distance, and at the same time, the motor 501 is used to drive the toggle rod 502 to rotate, so that the other end of the toggle rod 502 slides in the slide groove 603, thereby driving the swing frame 601 connected to the lever frame 602 to swing back and forth, so that the stone plate 606 swings back and forth to push the stones on the ground away, and when the stone plate 606 contacts the stone that cannot be pushed, the moving block 604 connected to the tension spring 605 moves up, thereby driving the stone plate 606 to move up to unload the force; When the toggle rod 502 rotates, the connected transmission pressure rod 503 will be driven to rotate, so that the transmission pressure rod 503 can contact and squeeze the sliding frame 801, so that the sliding frame 801 drives the connected rack 803 to move downward, so that the rack 803 drives the driving wheel 804 to rotate, and at this time the driving wheel 804 drives the transmission wheel 805 to rotate, so that the transmission wheel 805 drives the driven wheel 702 to rotate, thereby driving the fan blade 701 connected to the driven wheel 702 to rotate, and the external air is sucked into the air guide cover 7, and sprayed out through the air jet pipe 703 to blow away the sand on the ground, so as to facilitate the rolling distance measurement of the distance measuring roller 2.
