Description

Technical Field

[0001] The invention relates to the field of farmland geographic contour measurement, and in particular to a high-precision farmland geographic information collection device. Background Art

[0002] With the rapid development of modern agriculture, the demand for precision agriculture is becoming increasingly urgent. The development of geographic information science has provided a new data source and analysis method for agriculture, which can provide more detailed and accurate terrain information for precision agriculture, and is crucial for precision agriculture, land management, irrigation planning, etc. However, traditional manual measurement methods are inefficient and have limited accuracy, making it difficult to meet the requirements for a detailed description of farmland terrain contours.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the technical means for collecting farmland geographic information. In order to make a more accurate comparison, a Chinese patent with publication number CN219996045U discloses a geographic information collection device, including a fixed block, a distance measuring wheel, a support, a display and a cleaning mechanism. When in use, the distance measuring wheel is pushed to move, and the number of rotations of the distance measuring wheel is counted by a counter, so that the distance measurement value can be obtained through the number on the counter and the fixed circumference. At the same time, the cleaning mechanism scrapes the soil adhered to the surface of the wheel during the rolling of the wheel, thereby ensuring the accuracy of the distance measurement.

[0004] However, the above-mentioned geographic information collection device still has some shortcomings in actual use: for example, the above-mentioned device counts the number of rotations of the measuring wheel through a counter to obtain the length measured by the measuring wheel, thereby achieving the effect of measuring the distance of the geographic contour. However, when in use, the data measured by the measuring wheel and the counter can only obtain information about the length and distance of the ground, and cannot effectively and comprehensively collect and measure the geographic contour information of the farmland. Therefore, the above-mentioned device still has limitations during use.

[0005] Therefore, based on the above-stated views, there is still room for improvement in the existing technical means for collecting farmland geographic information. Summary of the invention

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 To Attachment Fig. 9 Embodiments of the present invention are described in detail.

[0032] The embodiment of the present application discloses a high-precision farmland geographic information acquisition device, which explains that the high-precision farmland geographic information acquisition device is mainly used in the process of collecting and processing farmland geographic contour information, and achieves the effect of effectively collecting and processing the farmland geographic contour information in terms of technical effect; in particular, during the collection process, while collecting the farmland contour length through a scanner, other geographic information related to the farmland is also collected, thereby improving the comprehensiveness of the collection of farmland geographic information; further, the geographic information acquisition device also collects the geographic height information of the farmland on the moving path through a scanner to obtain a relative height curve of the collected farmland geographic contour, thereby facilitating subsequent staff to carry out land management and planning according to the corresponding farmland height.

[0033] Reference Figure 1As shown, a high-precision farmland geographic information collection device includes a mounting plate 1, a distance measuring wheel 10, a mounting frame 2 and a scanner 3. The distance measuring wheels 10 are symmetrically connected at both ends of the mounting plate 1. Counters (not shown in the figure) are also provided on the mounting plate 1 corresponding to the two distance measuring wheels 10, which are used to count the number of rotations of the distance measuring wheels 10 to obtain the farmland contour length measured by the distance measuring wheels 10. A scraper (not shown in the figure) is also provided on the mounting plate 1 corresponding to the distance measuring wheels 10, which is used to scrape off the soil adhered to the distance measuring wheels 10. The mounting plate 1 is connected to the mounting frame 2, and a scanner 3 for collecting and processing farmland geographic contour information is installed through the mounting frame 2.

[0034] When in use, the measuring wheel 10 is driven to roll on the ground to move the mounting plate 1, the mounting frame 2 and the scanner 3. While moving, the scanner 3 is turned on to collect and record the geographical contour information of the farmland on the moving path. Then, the number of rotations of the measuring wheel 10 is counted by a counter during the movement. Then, the contour length of the farmland on the moving path of the measuring wheel 10 can be obtained through the number on the counter and the fixed circumference of the measuring wheel 10, thereby achieving the effect of collecting and processing the geographical contour information of the farmland, thereby providing the staff with more detailed and accurate geographical information, which is convenient for subsequent land planning and management.

[0035] Reference Figure 2 and Figure 3 As shown, a mounting frame 2 is used to install and limit a scanner 3; specifically, the mounting frame 2 includes a limiting sleeve 20, a sliding link 21, a driving member 22 and an adjusting member 23. The limiting sleeve 20 is inserted on the mounting plate 1, and a sliding link 21 with a telescopic structure is inserted in the limiting sleeve 20. The scanner 3 is installed on the upper end of the sliding link 21. A driving member 22 for controlling the rotation angle of the sliding link 21 is connected to the mounting plate 1, and an adjusting member 23 for driving the sliding link 21 to further adjust its position is also connected between the limiting sleeve 20 and the sliding link 21.

[0036] When in use, in the process of driving the device forward, the driving member 22 drives the sliding link 21 and the scanner 3 to rotate at an angle, so that the geographic information of different horizontal directions at the same position can be collected during the movement of the scanner 3. At the same time, the angle of the scanner 3 and the sliding link 21 is further adjusted by the adjusting member 23, so that the scanner 3 can adjust the pitch angle in the vertical direction while rotating horizontally, thereby driving the scanner 3 to collect the geographic contour information of the farmland at different angles, thereby improving the comprehensiveness of the collection of farmland information.

[0037] Reference Figure 3 and Figure 4As shown, the driving member 22 is used to control the rotation angle of the sliding link 21; specifically, the driving member 22 includes an extension block 220, an extension protrusion 221, a limiting slide groove 222, a limiting frame plate 223 and a limiting rotating rod 224. The sliding link 21 is integrally provided with a driving end, and the lower end of the sliding link 21 is connected to the extension block 220, and the extension block 220 is also connected to the extension protrusion 221 inserted on the limiting sleeve 20, and a limiting slide groove 222 for limiting the sliding path of the extension protrusion 221 is formed on the limiting sleeve 20, and the extension block 220 is also rotatably connected to the limiting frame plate 223, and the lower end of the limiting frame plate 223 is connected to the limiting rotating rod 224 connected to the mounting plate 1. It should be noted that the driving end is an existing motor drive technology.

[0038] When in use, the driving end drives the sliding link 21 to rotate, and the rotation of the sliding link 21 drives the extension block 220, the extension protrusion 221, the limit frame plate 223 and the limit rotating rod 224 to rotate around the axis of the sliding link 21 as the central axis, and the extension protrusion 221 rotates along the limit slide groove 222. At the same time, the rotation of the sliding link 21 also drives the scanner 3 at its upper end to rotate, so that the scanner 3 rotates at different angles to scan and collect the geographical contours of the farmland on the moving path.

[0039] Furthermore, the extended protrusion 221 is inserted into the limiting slide groove 222 to limit the rotation of the connected sliding link 21. During use, since the upper end of the sliding link 21 is also connected to the scanner 3, the sliding link 21 is easily shaken by the weight of the scanner 3 during the process of driving the device forward, thereby causing the positions of the sliding link 21 and the scanner 3 to be constantly skewed, affecting the accuracy of the data collected by the scanner 3. Therefore, in order to improve the stability of the scanner 3 and the sliding link 21 during the movement, reference is made to Figure 5 and Figure 6 As shown, a plurality of limit arc blocks 24 are connected to the mounting plate 1, and the plurality of limit arc blocks 24 are circumferentially and evenly abutted against the outer side surface of the sliding link 21 with the limit sleeve 20 as the axis, so as to avoid the problem that the sliding link 21 is skewed due to external interference. A limit slide bar 240 is arranged at one end of the limit arc block 24 away from the limit sleeve 20, and a bending link 241 connected to the mounting plate 1 is sleeved on the limit slide bar 240, and a limit spring 242 is sleeved on the limit slide bar 240 and is located between the connected limit arc block 24 and the bending link 241.

[0040] When in use, in the process of driving the entire device to move, when the sliding link 21 and the scanner 3 on its upper side tend to tilt to one side, the sliding link 21 will apply a driving force to the limit arc block 24 on its outer side to slide away from the limit sleeve 20. At this time, the movement of the limit arc block 24 drives the connected limit slide 240 to slide synchronously, and drives the connected limit spring 242 to be compressed. The limit spring 242 is compressed because it needs to be reset, and provides a driving force to slide toward the limit sleeve 20 to the connected and sliding limit arc block 24 and the limit slide 240, thereby avoiding the problem of the sliding link 21 and the scanner 3 being driven to tilt during the movement.

[0041] Reference Figure 5 and Figure 6 As shown, one side of the limiting arc block 24 close to the sliding link 21 is set as a slope, so that the end of the limiting arc block 24 close to the sliding link 21 can better fit and abut against the outer side of the sliding link 21 through the set slope.

[0042] Reference Figure 4 and Figure 5 As shown, the adjusting member 23 is used to drive the sliding link 21 to adjust the position; specifically, the adjusting member 23 includes a mounting cavity formed by the hollow inside of the mounting plate 1, and a plurality of guide sliders 230 are arranged in the mounting cavity for contacting and limiting the limiting sleeve 20, and the side of the guide slider 230 close to the limiting sleeve 20 is set as an inclined surface structure. In the initial state, the lower end of the limiting sleeve 20 contacts the middle part of the inclined surface section on the guide slider 230.

[0043] When in use, when the guide slider 230 is moved in the direction close to the middle limiting sleeve 20, the limiting sleeve 20 moves up along the inclined surface of the guide slider 230, and the limiting sleeve 20 moves up, driving the limiting slot 222 opened thereon to move up, and the limiting slot 222 moves up, driving the extension protrusion 221 and the extension block 220 to move up. Since the extension protrusion 221 is inserted in the limiting slot 222, and at the same time the extension block 220 is rotationally limited on the limiting frame plate 223, the extension protrusion 221 and the extension block 220 are driven to move up at this time, causing the extension block 220, the extension protrusion 221 and the sliding link 21 to deflect as a whole in the direction close to the mounting plate 1 with the rotation axis between the limiting frame plate 223 as the axial direction (that is, driving the scanner 3 and the sliding link 21 to deflect downward as a whole), thereby completing the further adjustment effect of the sliding link 21 and the scanner 3 position.

[0044] At this time, since the outer side of the sliding link 21 contacts the slope of the limiting arc block 24, the sliding link 21 fits more closely on the slope of the limiting arc block 24 after being deflected, thereby improving the stability of the sliding link 21 when being deflected.

[0045] On the contrary, after moving the guide slider 230 in the direction away from the limiting sleeve 20, the limiting sleeve 20 is driven to move downward, so that a relative position sliding is formed between the limiting sleeve 20 and the limiting slide groove 222 and the extension protrusion 221, the extension block 220 and the sliding link 21, driving the extension protrusion 221, the extension block 220, and the sliding link 21 as a whole to deflect in the direction away from the mounting plate 1 with the rotation axis between the limiting frame plate 223 as the axis (that is, driving the scanner 3 and the sliding link 21 to deflect upward as a whole), completing the effect of adjusting the position of the scanner 3, so that the scanner 3 can collect the geographical contour information of the farmland at different angles, so that the geographical information collected by the scanner 3 is more comprehensive and accurate.

[0046] Further, refer to Figure 4 and Figure 5 As shown, a section of the limiting sleeve 20 inserted in the installation cavity is sleeved with a limiting ring sleeve 231, and a clamping spring 232 is sleeved on the limiting sleeve 20 and located between the limiting ring sleeve 231 and the inner wall of the installation cavity, which is used to provide the limiting ring sleeve 231 and the limiting sleeve 20 with a driving force that always contacts the inclined surface of the guide slider 230. In the initial state, the clamping spring 232 is in a state of being compressed under force, and at this time, the lower end of the limiting sleeve 20 contacts the middle part of the inclined surface section of the guide slider 230.

[0047] When in use, after moving the guide slider 230 in the direction approaching the limit sleeve 20, the limit sleeve 20 moves up along the inclined surface of the guide slider 230. The upward movement of the limit sleeve 20 also drives the connected limit ring sleeve 231 to move up, and drives the clamping spring 232 to be further compressed, thereby providing the limit ring sleeve 231 and the limit sleeve 20 with a driving force to always slide downward. When the guide slider 230 is moved in the direction away from the limit sleeve 20, under the reset drive of the clamping spring 232, the limit sleeve 20 moves down and resets as the guide slider 230 moves away. By adjusting the relative position between the guide slider 230 and the limit sleeve 20, the sliding of the limit sleeve 20 is controlled, thereby achieving the effect of adjusting the deflection angle of the sliding link 21 and the scanner 3.

[0048] Reference Figure 4 and Figure 5As shown, a bending push rod 233 is connected to the side of the guide slider 230 away from the limiting sleeve 20, and a bidirectional screw rod 234 is threaded through the bending sections of the two bending push rods 233. The bidirectional screw rod 234 is provided with two threads in opposite directions, and the two bending push rods 233 are symmetrically connected to the two threaded sections. When in use, the bidirectional screw rod 234 is driven to rotate forward, and the two bending push rods 233 slide in the direction of approaching each other through the threads of the bidirectional screw rod 234. The movement of the two bending push rods 233 drives the two guide sliders 230 to slide in the direction of approaching each other, thereby achieving the effect of driving the limiting sleeve 20 to move up along the inclined surface of the guide slider 230; when the bidirectional screw rod 234 is driven to rotate in the opposite direction, the two bending push rods 233 slide in the direction of moving away from each other through the two threads on the bidirectional screw rod 234, and at this time, under the drive of the tightening spring 232, the limiting ring sleeve 231 and the limiting sleeve 20 are pushed to move downward.

[0049] Reference Figures 6 to 8 As shown, the sliding link 21 includes a driven sliding sleeve 210 and a driven sliding rod 211. The driven sliding sleeve 210 is connected to the extension block 220 and its outer side is abutted and limited by the limiting arc block 24. The driven sliding rod 211 is limited and inserted in the driven sliding rod 211. A tightening end 212 for tightening and limiting the extended driven sliding rod 211 is also provided on the driven sliding sleeve 210. As an optional embodiment, the tightening end 212 only needs to limit the driven sliding rod 211 after sliding on the driven sliding sleeve 210. In this example, the tightening end 212 uses a tightening screw threaded on the driven sliding sleeve 210 to tighten the outer side of the driven sliding rod 211 to tighten and limit the driven sliding rod 211 after sliding.

[0050] When in use, the driven slide rod 211 is moved up a certain distance along the inner wall of the driven sleeve 210, and then the locking screw is rotated to slide in the direction close to the driven slide rod 211, so that the end of the locking screw close to the driven slide rod 211 is pressed against the outer side surface of the driven slide rod 211, thereby achieving the effect of locking and limiting the driven slide rod 211 after sliding.

[0051] Further, in order to facilitate the staff to clearly understand the specific position height of the driven slide bar 211 after sliding, refer to Figure 8 and Fig. 9As shown, a plurality of scale marks 213 are evenly formed on the outer side surface of the driven slide rod 211. When in use, after the driven slide rod 211 slides in the driven sleeve 210, it also drives the plurality of scale marks 213 formed thereon to slide synchronously. After the driven slide rod 211 is driven to slide a certain distance, the sliding driven slide rod 211 is limited by the abutting end 212. At this time, the position height of the driven slide rod 211 is one of the scale marks 213 on the lower side displayed on the driven slide rod 211 relative to the driven sleeve 210 (that is, the scale mark 213 indicated by the uppermost end of the driven sleeve 210).

[0052] Furthermore, in order to improve the collection effect of farmland geographic contour information during the mobile process, refer to Figures 2 to 4 As shown, a through hole is commonly formed on the driven sliding rod 211, the driven sliding sleeve 210, the limit frame plate 223, the limit rotating rod 224 and the mounting plate 1, and a sliding probe rod 25 slidably inserted on the limit rotating rod 224 and the mounting plate 1 is connected in the through hole. Since the sliding probe rod 25 is slidably inserted in the through hole on the limit rotating rod 224, the sliding probe rod 25 always slides in the vertical direction along the limit rotating rod 224, so as to fit on the ground to improve the accuracy of the collection result. The sliding probe rod 25 is electrically connected to the scanner 3. In the initial state, the lower end of the sliding probe rod 25 is flush with the ground, and a ball is connected to the lower end of the sliding probe rod 25 to reduce the friction resistance of the sliding probe rod 25 when it slides on the ground. At this time, the position height information of the sliding probe rod 25 is collected in advance by the scanner 3 and recorded as L0.

[0053] When in use, after driving the device to move to any position, first drive the scanner 3 to rotate at different angles to collect the geographical contour information of the farmland at that location, and then drive the scanner 3 to reset and collect the position height information of the sliding probe rod 25 at this time. Since the sliding probe rod 25 is always in contact with the ground, after the position height information of the sliding probe rod 25 is collected by the scanner 3, the position height information of the farmland ground at this time can be determined, and the position height information of the sliding probe rod 25 at this time is collected and recorded as L1. This cycle is repeated many times to obtain the corresponding position information of the sliding probe rod 25 in turn: L2, L3, ... Ln-1, Ln, etc.

[0054] After completing the overall collection of the farmland geographic contour information, all the data obtained by the scanner 3 collecting the position height information of the sliding probe 25 are displayed, and at the same time, the above data are connected in series with a smooth curve. Based on this, the flatness information of the farmland after the collection is completed can be judged by observing the data curve at this time.

[0055] If the obtained data Ln is greater than the above-mentioned L0, it can be judged that the height of the farmland here is in a state of upward bulging; if the obtained data Ln is equal to the above-mentioned L0, it can be judged that the height of the farmland here is flush with the initial collection position; if the obtained data Ln is less than the above-mentioned L0, it can be judged that the height of the farmland at this time is in a state of downward sinking.

[0056] At this time, in combination with the farmland geographic contour information scanned and collected by the above-mentioned scanner 3, the overall contour height of the farmland can be judged to obtain the flatness information of the farmland, thereby facilitating the staff to make corresponding land planning and management based on the collected farmland geographic information.

[0057] During operation: the first step is to drive the device to move on the ground of the farmland to be collected, and measure the distance measuring wheel 10 through the counter to obtain the length of the moving path of the distance measuring wheel 10, that is, the length of the geographical contour of the farmland.

[0058] Step 2: When the device is driven to move, the farmland geographic information in the moving path is collected by the scanner 3, and the scanner 3 is driven to rotate at different angles to realize multi-angle information collection and improve the accuracy of the collected information.

[0059] Step 3: During the movement, the ground height information of the farmland on the moving path is also collected by the scanner 3, and the overall contour information of the farmland is obtained by combining the above scanned data.

[0060] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0061] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
