Description

Technical Field

[0001] The present invention mainly relates to the technical field of land measurement equipment, and specifically, it is a farmland operation area measurement device. Background Art

[0002] The traditional tool for measuring farmland area is a tape measure. Operators measure the dimensions of the farmland with the tape measure and then calculate the farmland operation area. Measuring with a tape measure requires operators to walk long distances, which is time-consuming and laborious. Due to the long depth of the farmland, multiple segments of measurement need to be superimposed. The soft tape measure deforms significantly over long distances, resulting in obvious measurement errors.

[0003] The existing Chinese patent with the publication number CN103791879A discloses an area measurement method based on a GPS area measuring instrument. Using the original handheld GPS area measuring instrument as a tool, the handheld GPS area measuring instrument is installed on the top of a telescopic rod. The base of the telescopic rod is hinged to the rearview mirror of a harvester, and a clamping hoop is provided at the hinged part of the base of the telescopic rod to clamp the telescopic rod. When measuring the land area, when the harvester travels the first circle along the edge of the farmland, when one circle of travel is completed, the crops are harvested and the area of the farmland is measured, saving the time of manually holding the GPS area measuring instrument and walking along the farmland, and improving the operation efficiency.

[0004] However, the farmland operation area measurement device has the following defects in specific use: When the existing farmland operation area measurement devices in the prior art are in use, they are generally handheld or installed on large harvesters. On the one hand, the GPS farmland area measurement device lacks a stable support structure, resulting in easy shaking due to external interference during the measurement process, affecting the measurement accuracy; on the other hand, these devices are often not flexible enough in height and angle adjustment. Placing them on the harvester may cause the device to be subjected to large vibrations, resulting in device instability and thus affecting the accuracy of the measurement results. Summary of the Invention

[0005] To solve the deficiencies of the prior art, the present invention provides a farmland operation area measurement device, which is realized through the following technical solutions: A farmland operation area measurement device includes a base. A number of evenly distributed ground nails are fixedly installed on the bottom surface of the base. A column is fixedly installed at the center of the top surface of the base. A sliding sleeve is slidably fitted on the column. A limiting component is provided on the sliding sleeve, and the position of the sliding sleeve can be adjusted through the limiting component. A ring is rotatably installed outside the sliding sleeve. An adjustable bracket is provided on one side of the ring. A clamping component is installed on the adjustable bracket, and a GPS acreage meter is clamped and installed by the clamping component. Further, the limiting component includes a first rack. A vertical groove is formed in the front surface of the column, and the first rack is fixedly installed in the vertical groove. A limiting block is slidably installed at the front part of the top surface of the sliding sleeve. The limiting block is connected to the sliding sleeve through an elastic reset component, and the rear end of the limiting block can be inserted between two adjacent tooth blocks of the first rack.

[0006] Further, the elastic reset component includes a limiting plate. Limiting plates are fixedly installed on both sides of the limiting block respectively. Through holes are formed in the front surfaces of the limiting plates. Guide rods are slidably installed in the through holes respectively. Support plates are fixedly installed at both ends of the guide rods respectively. The bottom surfaces of the support plates are fixedly connected to the top surface of the sliding sleeve, and a first spring is sleeved on the outer part of the guide rod. The first spring is located in front of the limiting plate.

[0007] Further, a pull ring is fixedly installed at the front end of the limiting block.

[0008] Further, an annular groove is formed in the middle of the sliding sleeve, and the circular ring is rotatably installed in the groove through a damping bearing.

[0009] Further, the adjustable bracket includes: A mounting seat, one side of the circular ring is fixedly installed with the mounting seat, and the mounting seat is of a U-shaped structure; A connecting seat, the connecting seat is rotatably installed in the mounting seat; An adjusting bolt, the adjusting bolt longitudinally penetrates through the mounting seat and the connecting seat arranged inside it from front to back, and the connecting seat can rotate with the adjusting bolt as a fulcrum; A locking nut, the locking nut is fixedly installed on the rear surface of the mounting seat, and the adjusting bolt passes through the locking nut and is threadedly connected to it; A clamping component is fixedly installed at the outer end of the connecting seat.

[0010] Further, the clamping component includes a bottom plate. A support plate is fixedly installed at the bottom of the outer side of the bottom plate. A gear groove is formed inside the bottom plate. Chute are formed on both sides of the bottom plate respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This device fixes the base with ground nails, which can ensure the stability of the device during the measurement process, avoid measurement errors caused by shaking. The sliding of the sliding sleeve on the column and the precise adjustment of the limit component enable the GPS area meter to be stably adjusted to a suitable height for measurement, reducing measurement errors caused by height changes. Through precise height and angle adjustment, as well as a stable support structure, this device makes the measurement process faster and more accurate, reducing the time wasted on repeated measurements and error correction. The design of the device enables users to adapt to different terrains and measurement requirements more quickly, improving the measurement efficiency.

[0012] 2. The sliding design of the sliding sleeve on the column allows the height of the GPS area meter to be flexibly adjusted according to actual measurement needs.

By manually pushing the limit block, the position of the sliding sleeve can be adjusted, and it will automatically snap into the teeth of the new position under the action of the elastic reset component to achieve stable locking, improving the convenience of adjustment. The design of the clamping component simplifies the clamping and releasing process of the GPS area meter. Users only need to place the GPS area meter between the two clamping plates. After loosening the clamping plates, under the action of the tension of the second spring, the clamping plates can automatically clamp the GPS area meter, improving the simplicity of operation.

[0017] Embodiment: A device for measuring the area of farmland operations As Figure 1 - 6 shows, a device for measuring the area of farmland operations, its specific structure includes: A base 1, characterized in that: a plurality of uniformly distributed ground nails 2 are fixedly installed on the bottom surface of the base 1, a column 3 is fixedly installed at the center of the top surface of the base 1, a handle is fixedly installed at the upper end of the column 3, a sliding sleeve 4 is slidably fitted on the column 3, a limiting component is provided on the sliding sleeve 4, and the position of the sliding sleeve 4 can be adjusted through the limiting component. A ring 5 is rotatably installed outside the sliding sleeve 4, an adjustable bracket 6 is provided on one side of the ring 5, a clamping component is installed on the adjustable bracket 6, and a GPS area meter 7 is clamped and installed on the clamping component. The GPS area meter can be selected as the Yili S5 high-precision GPS area meter. The above working principle: When this device is in use, the base 1 is fixed by the ground nails 2 to ensure that the device is stable and does not shake. The ground nails 2 can be inserted into the farmland to keep the bottom surface of the base 1 in contact with the ground, thereby maintaining the stability of this device. Moreover, after moving the position, it can still ensure that the distance between the GPS area meter 7 and the ground remains the same at different measurement points, thereby reducing the measurement error after the position of the GPS area meter 7 moves. The sliding of the sliding sleeve 4 on the column 3 and the adjustment of the limiting component adjust the GPS area meter 7 to a suitable height for measurement. The design of the ring 5 and the adjustable bracket 6 increases the flexibility of this device, enabling the GPS area meter 7 to adapt to different terrains and measurement requirements, and improving the measurement efficiency and accuracy.

[0018] The limit assembly includes a first rack 8, a vertical slot 9 is provided in front of the column 3, the first rack 8 is fixedly installed in the vertical slot 9, a limit block 10 is installed in the front part of the top surface of the sliding sleeve 4 in a sliding cooperation, the limit block 10 is connected to the sliding sleeve 4 through an elastic reset assembly, and the rear end of the limit block 10 can be inserted between two adjacent tooth blocks of the first rack 8. When the height of the sliding sleeve 4 needs to be adjusted, the limit block 10 is manually pushed to disengage it from the teeth of the first rack 8, and then the sliding sleeve 4 is moved. After adjusting the position of the sliding sleeve 4, the limit block 10 is released. Under the action of the elastic reset assembly, the limit block 10 slides backward to reset, and the elastic reset assembly pushes the limit block 10 to automatically snap into the teeth of the new position, thereby achieving stable locking. This design simplifies the height adjustment process and improves the accuracy and convenience of adjustment.

[0019] The elastic reset assembly includes a limit plate 11, the limit plates 11 are fixedly installed on both sides of the limit block 10, a through hole 12 is provided in the front of the limit plate 11, and a guide rod 13 is slidably installed in the through hole 12, and a support plate 14 is fixedly installed at both ends of the guide rod 13, and the bottom surface of the support plate 14 is fixedly connected to the top surface of the sliding sleeve 4, and the outer part of the guide rod 13 is sleeved with a first spring 15, the first spring 15 is located at the front of the limit plate 11, one end of the first spring 15 is fixedly connected to the front of the corresponding limit plate 11, and the other end of the first spring 15 is fixedly connected to the back of the corresponding support plate 14 located at the front side. When the limit block 10 is manually pushed, the first spring 15 is compressed and deformed. When the external force disappears, the first spring 15 releases energy to push the limit block 10 to reset, ensuring the stability of the position of the sliding sleeve 4. This design not only improves the stability of the device, but also simplifies the operation process.

[0020] A pull ring 16 is fixedly mounted on the front end of the limit block 10. The design of the pull ring 16 makes it more convenient to manually operate the limit block 10, thereby improving the adjustment efficiency and user experience.

[0021] The middle of the sleeve 4 is provided with an annular groove 17, and the ring 5 is rotatably mounted in the groove 17 via a damping bearing. The design of the damping bearing enables the ring 5 to stably rotate in the groove 17, and at the same time has a certain damping effect, preventing accidental rotation due to external interference, thereby improving the measurement accuracy and stability.

[0022] The adjustable bracket 6 includes: a mounting base 61, with the mounting base 61 fixedly installed on one side of the ring 5, and the mounting base 61 being of a U-shaped structure; a connecting seat 62, with the connecting seat 62 rotatably installed within the mounting base 61; an adjusting bolt 63, with the adjusting bolt 63 longitudinally penetrating the mounting base 61 and the connecting seat 62 arranged inside it from front to back, and the connecting seat 62 being able to rotate with the adjusting bolt 63 as a fulcrum; a locking nut 64, with the locking nut 64 fixedly installed at the back of the mounting base 61, and the adjusting bolt 63 passing through the locking nut 64 and being threadedly connected thereto; and a clamping assembly fixedly installed at the outer end of the connecting seat 62.

[0023] By rotating the adjusting bolt 63, the clamping effect of the mounting base 61 on the connecting seat 62 can be reduced, enabling the connecting seat 62 to rotate more easily, changing the angle of the connecting seat 62 relative to the mounting base 61. Then, through the mutual cooperation of the adjusting bolt 63 and the locking nut 64, the mounting base 61 and the connecting seat 62 can be locked again to fix the angle. This design enables the GPS area meter 7 to adjust the angle more flexibly, improving the adaptability and accuracy of measurement.

[0024] The clamping assembly includes a bottom plate 18, with a support plate 19 fixedly installed at the bottom outside the bottom plate 18, a gear groove 20 formed inside the bottom plate 18, sliding grooves 21 respectively formed on both sides of the bottom plate 18, the upper and lower parts of the gear groove 20 being respectively communicated with the corresponding sliding grooves 21, a gear 22 rotatably installed within the gear groove 20, second racks 23 meshing with the gear 22 respectively slidably fitted within the sliding grooves 21, clamping plates 24 respectively fixedly installed at the outer ends of the second racks 23, the two clamping plates 24 being symmetric to each other, and second springs 25 respectively fixedly installed at the inner ends of the second racks 23. When it is necessary to clamp the GPS area meter 7, first move the clamping plates 24 outwards, and the clamping plates 24 drive the second racks 23 connected thereto to move synchronously. At this time, the second springs 25 are stretched. Under the mutual cooperation of the second racks 23 and the gear 22, the two clamping plates 24 can move synchronously. Place the GPS area meter 7 between the two clamping plates 24. After releasing the clamping plates 24, under the pulling force of the second springs 25, the second racks 23 move in the reverse direction to reset, and at the same time drive the clamping plates 24 to move towards the center to clamp the GPS area meter 7. This structural design not only simplifies the clamping and releasing process of the GPS area meter 7, but also improves the clamping stability and safety.
