Description

Technical Field

[0001] The invention relates to the field of garden technology, in particular to a distance measuring device for garden planting. Background Art

[0002] Garden engineering surveying refers to the measurement and data collection of garden sites in accordance with relevant specifications and standards, using modern surveying and mapping technology and instruments and equipment during the stages of garden planning and design, construction management and garden green space acceptance, so as to provide accurate spatial data and basic information for the reasonable layout and construction of garden projects. Garden engineering surveying includes the measurement of garden site boundaries, mapping of topography, measurement of building structures, investigation of green space vegetation and other aspects, which is an important part of garden projects. When conducting boundary measurements, it is necessary to map the boundaries of the garden site and determine the geographical location and spatial scope of the garden green space.

[0003] The existing distance measuring equipment still has the following problems during use: in the process of measuring the garden, the area of ​​the land is calculated by the number of rotations of the roller, and when the roller passes through a place with a protruding slope during its movement, the distance the roller travels is not the straight-line distance of the measured part of the land, but the length of the hypotenuse, which makes the measurement data of this part larger, resulting in calculation errors, and when there are small pieces of debris on the route, it will also affect the measurement operation, which will not only affect the movement but also cause route deviation, thereby affecting the accuracy of garden planting work. Therefore, the present application provides a distance measuring device for garden planting to meet the needs. Summary of the invention

[0004] The purpose of the present invention is to provide a distance measuring device for garden planting, so as to solve the problem that the existing land measuring devices on the market currently mentioned in the above background technology, during use, when the roller passes through a place with a protruding slope, the measurement data of this part is too large, thereby causing calculation errors, and when there are small pieces of debris on the route, it will also affect the measurement operation, which will not only affect the travel but also cause route deviation, thereby affecting the accuracy of garden planting work.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A distance measuring device for garden planting comprises a roller, a counter is arranged on the left side of the roller, and a shaft is installed in the middle of the roller, the shaft passes through the interior of a fixed cover and is connected to the rotating shaft of the counter, the fixed cover is installed on the left side of the counter, and the rotating shaft passes through a bearing and is connected to the left side of the counter, a vertical rod with adjustable length is connected to the right side of the counter external bearing, an operating handle is installed on the top of the vertical rod, and a display screen and operating buttons are arranged on the operating handle, and a laser radar sensor is installed at the bottom edge of the counter, and the laser radar sensor is located on one side of the roller's travel direction; an adjustment component, the adjustment component is arranged inside the fixed cover, and the adjustment component adjusts the use state of the counter according to the road conditions; a stroke correction component, the stroke correction component is installed inside the fixed cover and outside the left side of the counter, and the stroke correction component corrects the measured distance according to the path calculation value; a roadblock clearing component, the roadblock clearing component is arranged on the outside of the fixed cover, and the roadblock clearing component clears obstacles on the roller's travel route.

[0006] Optionally, the adjustment assembly includes a mounting plate, and the mounting plate is arranged in the middle of the inner side of the fixed cover, and the front and rear ends of the right side of the mounting plate are symmetrically connected to electric push rods, and the electric push rods are fixed to the inner wall of the fixed cover.

[0007] Optionally, the middle bearing of the mounting plate is connected to a movable shaft, and the movable shaft is connected between the shaft rod and the rotating shaft, and the left end of the shaft rod and the right end of the rotating shaft are respectively provided with a first socket and a second socket, and the movable shaft is adjusted by moving to adjust the use status of the shaft rod and the second socket.

[0008] Optionally, one end of the movable shaft is set to a rectangular structure and the other end is set to a cylindrical structure, and the rectangular end of the movable shaft is slidably connected to the first socket on the shaft rod, and the cylindrical end of the movable shaft is slidably connected to the second socket on the rotating shaft through an electric push rod, and the sliding range of the rectangular end of the movable shaft is smaller than the depth of the first socket, and the sliding range of the cylindrical end of the movable shaft is greater than the depth of the second socket.

[0009] Optionally, the stroke correction assembly includes a driving gear, and the driving gear is installed on the outside of the counter through a motor, and the outside of the driving gear is meshedly connected with a driven gear, and the driven gear is fixed to the outside of the rotating shaft.

[0010] Optionally, the diameter of the driving gear is smaller than that of the driven gear, and the driven gear drives the rotating shaft to rotate inside the counter, and the motor on the counter drives the rotating shaft through the driving gear and the driven gear to perform data correction on the counter.

[0011] Optionally, the roadblock clearing assembly includes a connecting rod, and the connecting rod is installed on the outside of the fixed cover through a motor, and a cleaning plate is fixed to the bottom of the connecting rod, and the cleaning plate is located in front of the moving direction of the roller.

[0012] Optionally, the connecting rod forms a rotating structure through a motor on the fixed cover, and the connecting rod drives the cleaning plate to rotate synchronously, and the cleaning plate is set as a "V" shape as a whole, and the outer side of the cleaning plate is set as a triangular structure.

[0013] Optionally, a single chip microcomputer is provided inside the counter, and a speed sensor for detecting the shaft is installed on the inner wall of the fixed cover, and after the laser radar sensor detects the height change, it transmits the signal to the electric push rod through the single chip microcomputer, thereby disconnecting the shaft from the rotating shaft. During the disconnection time, the rotation speed of the shaft detected by the speed sensor can be used to obtain the length of the slope according to S=V*T, where S is the distance, V is the speed, and T is the time. The laser radar sensor determines the three-dimensional coordinates of the slope through laser scanning and radar positioning to obtain accurate position data, and determines the travel time from the lowest point to the highest point through the single chip microcomputer, and cooperates with calculation to determine the distance between the highest point of the slope and the ground. The length of the slope and the height of the highest point of the laser radar sensor are known, which is equivalent to the known lengths of the two right-angled sides of the right triangle. Then, the straight-line length of the protruding part of the land can be obtained according to the Pythagorean theorem a²+b²=c², thereby obtaining an accurate measurement value.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, during use, when passing through a sloped area, the straight-line distance can be obtained based on the actual operating data, making the measurement data more accurate and reducing the actual error. In addition, on the route of travel, small pieces of debris can be automatically cleaned up to avoid affecting the measurement operation and thus affecting the accuracy of the garden planting work.

[0015] Through the set adjustment component, when passing through a sloped position, the electric push rod drives the mounting plate to move. After the mounting plate moves, the shaft rod and the counter are in a disconnected state, the movable shaft disengages from the second socket, and the movable shaft and the first socket always remain connected. When the roller drives the shaft rod to rotate, the rotation of the shaft rod cannot be transmitted to the rotating shaft, and then the counter will not count. After completely passing through the sloped ground, the electric push rod will push the mounting plate to reset, and the movable shaft will be plugged into the second socket, thereby synchronizing the rotation of the shaft rod and the rotating shaft again, and the counter continues to count, and so on. When encountering a protruding part with a slope, the shaft rod and the rotating shaft are disconnected, and the connection state is restored after reaching the flat section, thereby avoiding directly calculating the section with inaccurate values ​​into the measured value, making the measurement data more accurate and reducing errors.

[0016] By setting up the stroke correction component, the speed sensor will detect the speed of the shaft during the period when the shaft and the shaft are disconnected. After the speed and time are known, the length of the slope can be obtained. The height of the protruding land is determined by the laser radar sensor through laser scanning and radar positioning to obtain accurate position data. The lowest point of the slope is taken as the starting point and the highest point as the end point. The time of passing through the area is measured by the laser radar sensor in conjunction with the single-chip microcomputer, and then the rotation speed of the shaft when passing through the area is measured in conjunction with the speed sensor to facilitate subsequent calculations. Then, the straight-line distance of the protruding land part can be calculated according to the Pythagorean theorem. The straight-line distance is the actual measured length. The motor outside the counter drives the driving gear to rotate. After the driving gear rotates, the shaft is driven to rotate through the driven gear. After the shaft rotates, the actual value is compensated to the counter, thereby obtaining more accurate measurement data.

[0017] By setting up a roadblock cleaning component, when encountering a roadblock of soil during the travel process, the cleaning board cleans the roadblock, and the soil block is pushed to both sides of the travel route along the triangular surface of the cleaning board to avoid hindering the progress of the measurement work, and when passing through a sloped position, the motor in the side wall of the fixed cover drives the connecting rod and the cleaning board to rotate synchronously, so that when the roller passes through a sloping ground, the cleaning board can still remain parallel to the travel direction, thereby maintaining the effect of clearing the roadblock and avoiding affecting the progress of the measurement work.

[0036] like Figures 1 to 10 As shown, an embodiment of the present invention provides a distance measuring device for garden planting, including a roller 1, and a counter 2 is arranged on the left side of the roller 1, and a shaft 3 is installed in the middle of the roller 1, the shaft 3 passes through the interior of the fixed cover 4 and is connected with the rotating shaft 5 of the counter 2, and the fixed cover 4 is installed on the left side of the counter 2, and the rotating shaft 5 passes through the bearing and is connected to the left side of the counter 2, and the right side of the counter 2 is connected to the external bearing with an adjustable length vertical rod 6, and an operating handle 7 is installed on the top of the vertical rod 6, and a display screen and operating buttons are arranged on the operating handle 7, and a laser radar sensor 8 is installed at the bottom edge of the counter 2, and the laser radar sensor 8 is located on one side of the moving direction of the roller 1.

[0037] As an implementation method in this embodiment, Figures 4 to 8As shown, the adjustment component 9 is arranged inside the fixed cover 4, and the adjustment component 9 adjusts the use state of the counter 2 according to the road conditions. The adjustment component 9 includes a mounting plate 901, and the mounting plate 901 is arranged in the middle of the inner side of the fixed cover 4, and the front and rear ends of the right side of the mounting plate 901 are symmetrically connected with electric push rods 902, and the electric push rods 902 are fixed on the inner wall of the fixed cover 4. When passing through a slope position, the electric push rod 902 on the inner wall of the fixed cover 4 runs, thereby driving the mounting plate 901 to move. After the mounting plate 901 moves, the shaft rod 3 and the counter 2 are in a disconnected state, thereby avoiding directly calculating the road section with inaccurate values ​​into the measured values. The middle bearing of the mounting plate 901 is connected to a movable shaft 903, and The movable shaft 903 is connected between the shaft rod 3 and the rotating shaft 5, and the left end of the shaft rod 3 and the right end of the rotating shaft 5 are respectively provided with a first socket 904 and a second socket 905, and the movable shaft 903 is adjusted by moving to adjust the use status with the shaft rod 3 and the second socket 905. One end of the movable shaft 903 is set as a rectangular structure, and the other end is set as a cylindrical structure. The rectangular end of the movable shaft 903 is slidingly connected with the first socket 904 on the shaft rod 3, and the cylindrical end of the movable shaft 903 is slidingly connected with the second socket 905 on the rotating shaft 5 through the electric push rod 902, and the sliding range of the rectangular end of the movable shaft 903 is smaller than the depth of the first socket 904, and the sliding range of the cylindrical end of the movable shaft 903 is greater than the depth of the second socket 905.

[0038] In this embodiment, when the mounting plate 901 moves, it drives the movable shaft 903 to move synchronously, and the movable shaft 903 disengages from the second socket 905 on the rotating shaft 5, and the rectangular end of the movable shaft 903 is inserted deeper from the connection state of the first socket 904. At this time, when the roller 1 drives the shaft rod 3 to rotate, the rotation of the shaft rod 3 cannot be transmitted to the rotating shaft 5, and then the counter 2 will not count. After completely passing through the sloping ground, the electric push rod 902 will push the mounting plate 901 to reset, so that the movable shaft 903 is plugged into the second socket 905 on the rotating shaft 5, and the rectangular end of the movable shaft 903 slides inside the first socket 904, but always remains connected, thereby synchronizing the rotation of the shaft rod 3 and the rotating shaft 5 again, and the counter 2 continues to count, and repeats this process. Once a protruding part with a slope is encountered, the shaft rod 3 and the rotating shaft 5 are disconnected, and the connection state is restored after reaching the flat section.

[0039] As an implementation method in this embodiment, Figures 4 to 6 and Figures 9 and 10As shown, the stroke correction component 10 includes a driving gear 101, and the driving gear 101 is installed on the outside of the counter 2 through a motor, and the outside of the driving gear 101 is meshed with a driven gear 102, and the driven gear 102 is fixed to the outside of the rotating shaft 5. The diameter of the driving gear 101 is smaller than the diameter of the driven gear 102, and the driven gear 102 drives the rotating shaft 5 to rotate inside the counter 2, and the motor on the counter 2 drives the rotating shaft 5 through the driving gear 101 and the driven gear 102 to perform data correction on the counter 2. After the actual measured length is obtained, the numerical signal is transmitted to the motor on the counter 2 through the single-chip microcomputer, and the motor drives the driving gear 101 to rotate. After the driving gear 101 rotates, it drives the rotating shaft 5 to rotate through the driven gear 102. After the rotating shaft 5 rotates, the actual value is compensated to the counter 2, thereby obtaining more accurate measurement data.

[0040] In this embodiment, a stroke correction component 10 is installed inside the fixed cover 4 and outside the left side of the counter 2, and the stroke correction component 10 corrects the measured distance according to the path calculation value. A single chip microcomputer is arranged inside the counter 2, and a speed sensor for detecting the shaft 3 is installed on the inner wall of the fixed cover 4. After the laser radar sensor 8 detects the height change, it transmits the signal to the electric push rod 902 through the single chip microcomputer to disconnect the connection with the rotating shaft 5. During the disconnection time, the lowest point of the earth slope is taken as the starting point and the highest point is taken as the end point. The rotation speed of the shaft 3 detected by the speed sensor can be used to obtain the length of the slope according to S=V*T, where S is the distance and V is the speed. T is time. The length of the slope and the height of the highest point of the laser radar sensor 8 are known, which is equivalent to the known lengths of the two right-angled sides of the right triangle. Then, the straight-line length of the protruding part of the land can be obtained according to the Pythagorean theorem a²+b²=c², thereby obtaining an accurate measurement value. During the period when the shaft 3 and the rotating shaft 5 are disconnected, the speed sensor will detect the speed of the shaft 3. After the speed and time are known, the length of the slope can be obtained, and the height of the protruding land is detected by the laser radar sensor 8. Then, the straight-line distance of the protruding land part can be calculated according to the Pythagorean theorem. The straight-line distance is the actual measured length. After each protruding position is passed, time for numerical compensation is left before continuing the measurement.

[0041] As an implementation method in this embodiment, Figures 1 to 8As shown, the roadblock cleaning component 11 is arranged on the outside of the fixed cover 4, and the roadblock cleaning component 11 cleans the obstacles on the travel route of the roller 1. The roadblock cleaning component 11 includes a connecting rod 111, and the connecting rod 111 is installed on the outside of the fixed cover 4 through a motor, and a cleaning plate 112 is fixed to the bottom of the connecting rod 111, and the cleaning plate 112 is located in front of the travel direction of the roller 1. The connecting rod 111 forms a rotating structure through the motor on the fixed cover 4, and the connecting rod 111 drives the cleaning plate 112 to rotate synchronously, and the cleaning plate 112 is arranged as a "V" shape as a whole, and the outer side of the cleaning plate 112 is arranged as a triangular structure.

[0042] In this embodiment, when the device is moving, the cleaning plate 112 at the bottom of the connecting rod 111 on the fixed cover 4 cleans the roadblocks, and the soil blocks are pushed to both sides of the travel route along the triangular surface of the cleaning plate 112, thereby cleaning the roadblocks. When passing through a sloped position, the laser radar sensor 8 will first detect the change in road conditions. When the roller 1 passes through the sloped ground, the motor on the fixed cover 4 is started to drive the connecting rod 111 and the cleaning plate 112 to rotate synchronously, so that the cleaning plate 112 can still maintain a parallel state with the travel direction, that is, the cleaning plate 112 is in parallel contact with the ramp surface, thereby maintaining the cleaning effect of the roadblocks and preventing the roadblocks from affecting the measurement work.

[0043] The working principle of the technical solution provided by the present invention is as follows: First, the main parts of the device are introduced. When measuring land, hold the operating handle 7 on the vertical rod 6. The length of the vertical rod 6 can be adjusted according to the height of the user. The display screen on the operating handle 7 can display the value of the counter 2. The operating button can be used for switching, unit conversion, reading stored data and clearing. When measuring, the roller 1 will roll, thereby causing the shaft 3 to rotate. The rotation of the shaft 3 drives the rotating shaft 5 to rotate synchronously through the mechanism inside the fixed cover 4. After the rotating shaft 5 rotates, the rear counter 2 counts. The laser radar sensor 8 at the bottom of the counter 2 determines the three-dimensional coordinates through laser scanning and radar positioning, and obtains accurate position data, thereby determining the distance between the highest point of the slope and the ground. The height between the measuring device and the ground can be detected, and then when passing through a protruding part with a slope, the time of passing the position and the height of the highest point can be timely known, which is convenient for subsequent processing.

[0044] When passing through a sloped position, the electric push rod 902 on the inner wall of the fixed cover 4 runs, thereby driving the mounting plate 901 to move. After the mounting plate 901 moves, the shaft 3 and the counter 2 are in a disconnected state, thereby avoiding directly calculating the road section with inaccurate values ​​into the measured value. When the mounting plate 901 moves, it drives the movable shaft 903 to move synchronously, and the movable shaft 903 is disengaged from the second socket 905 on the rotating shaft 5. The rectangular end of the movable shaft 903 is inserted deeper from the connection state of the first socket 904. At this time, when the roller 1 drives the shaft 3 to rotate, the shaft 3 The rotation cannot be transmitted to the rotating shaft 5, and the counter 2 will not count. After completely passing through the sloping ground, the electric push rod 902 will push the mounting plate 901 to reset, so that the movable shaft 903 is plugged into the second socket 905 on the rotating shaft 5. The rectangular end of the movable shaft 903 slides inside the first socket 904, but always remains connected, thereby synchronizing the rotation of the shaft rod 3 and the rotating shaft 5 again, and the counter 2 continues to count, and repeats this process. Once a protruding part with a slope is encountered, the shaft rod 3 and the rotating shaft 5 are disconnected, and the connection is restored after reaching the flat section.

[0045] During the disconnection time, the lowest point of the earth slope is taken as the starting point and the highest point as the end point. The rotation speed of the shaft 3 detected by the speed sensor can be used to obtain the length of the slope according to S=V*T, where S is the distance, V is the speed, and T is the time. The slope length and the height of the highest point of the laser radar sensor 8 are known, which is equivalent to the known lengths of the two right-angled sides of the right triangle. Then, the straight-line length of the protruding part of the land can be obtained according to the Pythagorean theorem a²+b²=c², thereby obtaining an accurate measurement value. During the disconnection period between the shaft 3 and the rotating shaft 5, the speed sensor will detect the speed of the shaft 3. After the speed and time are known, it can be obtained. The length of the slope, and the height of the protruding land is detected by the laser radar sensor 8, and then the straight-line distance of the protruding land part can be calculated according to the Pythagorean theorem. The straight-line distance is the actual measured length. Each time after passing the protruding position, time is left for numerical compensation, and then the measurement is continued. After the actual measured length is obtained, the numerical signal is transmitted to the motor on the counter 2 through the single-chip microcomputer. The motor drives the driving gear 101 to rotate. After the driving gear 101 rotates, it drives the rotating shaft 5 to rotate through the driven gear 102. After the rotating shaft 5 rotates, the actual value is compensated to the counter 2, thereby obtaining more accurate measurement data.

[0046] In order to automatically clean up small debris and soil blocks on the route to avoid affecting the measurement work, the following solution is proposed. Please refer to Figures 1 to 8As shown, when the device is moving, the cleaning plate 112 at the bottom of the connecting rod 111 on the fixed cover 4 cleans the roadblocks, and the soil blocks are pushed to both sides of the travel route along the triangular surface of the cleaning plate 112, thereby cleaning the roadblocks. When passing through a sloped position, the laser radar sensor 8 will first detect the change in road conditions. When the roller 1 passes through the sloped ground, the motor on the fixed cover 4 is started and drives the connecting rod 111 and the cleaning plate 112 to rotate synchronously, so that the cleaning plate 112 can still maintain a parallel state with the travel direction, that is, the cleaning plate 112 is in parallel contact with the ramp surface, thereby maintaining the cleaning effect of the roadblocks and preventing the roadblocks from affecting the measurement work.

The gardening distance measuring device according to claim 5, characterized in that: The diameter of the driving gear is smaller than that of the driven gear, and the driven gear drives the rotating shaft to rotate inside the counter, and the motor on the left side of the counter drives the rotating shaft through the driving gear and the driven gear to perform data correction on the counter.

7. The gardening distance measuring device according to claim 6, characterized in that: The roadblock cleaning assembly comprises a connecting rod, and the connecting rod is installed on the outside of the fixed cover through a motor, and a cleaning plate is fixed to the bottom of the connecting rod, and the cleaning plate is located in front of the moving direction of the roller.

8. The garden planting distance measuring device according to claim 7, characterized in that: The connecting rod forms a rotating structure through the motor on the fixed cover, and the connecting rod drives the cleaning plate to rotate synchronously, and the cleaning plate is overall configured as a "V"-shaped structure, and the outer side of the cleaning plate is configured as a triangular structure.

9. The garden planting distance measuring device according to claim 8, characterized in that: A single chip microcomputer is provided inside the counter, and a speed sensor for detecting the shaft rod is installed on the inner wall of the fixed cover. After the laser radar sensor detects the height change, it transmits the signal to the electric push rod through the single chip microcomputer, thereby disconnecting the shaft rod from the rotating shaft. During the disconnection time, the rotation speed of the shaft rod detected by the speed sensor can be used to obtain the length of the slope according to S=V*T, where S is the distance, V is the speed, and T is the time. The laser radar sensor determines the three-dimensional coordinates of the slope through laser scanning and radar positioning to obtain accurate position data, and determines the travel time from the lowest point to the highest point through the single chip microcomputer, and cooperates with calculation to determine the distance between the highest point of the slope and the ground. The length of the slope and the height of the highest point of the laser radar sensor are known, which is equivalent to the known lengths of the two right-angled sides of the right triangle. Then, the straight-line length of the protruding part of the land can be obtained according to the Pythagorean theorem a²+b²=c², thereby obtaining an accurate measurement value.
