[0002] Farmland planning is also called internal farmland planning. It is a comprehensive arrangement of measures to rationally organize the use of farmland on the premise of a given farmland area. With the development of society, more and more rural people go out to work, which leads to the abandonment of some farmland. The rapid development of industry has led to a large amount of farmland being used for industry and living. How to make limited farmland be used as efficiently as possible requires more accurate and reasonable measurement and planning.

[0003] In the prior art, Chinese Patent Publication No. CN215177747U discloses a farmland measurement and planning device, which includes a vertical rod, a connecting hole, a first latch, a first spring and a pull ring; by pulling the pull ring, the first spring is in a compressed state, and when the first latch is completely withdrawn from the connecting hole, the number of vertical rods is increased or decreased according to the height of the surveyor; when the pull ring is released, the first spring returns to a natural state due to the elastic force, and the first latch simultaneously penetrates the connecting holes of two adjacent vertical rods located on the same horizontal plane, thereby realizing the height adjustment of the farmland measurement and planning equipment.

[0031] Furthermore, the protective component includes a protective cover 18, which is located above the load-bearing plate 1. The side wall of the load-bearing plate 1 is symmetrically provided with a plurality of sockets 20. The top surface of the load-bearing plate 1 is provided with a snap-in groove 19 matching the protective cover 18, and the snap-in groove 19 is connected to the socket 20.

[0035] Working principle: When a person needs to use the device, the person first adjusts the telescopic rod 10 to the required length and rotates the second threaded column 11 to thread the second threaded column 11 with the second threaded ring 12. After the second threaded column 11 is installed, the person places the connecting plate 4 under the load-bearing plate 1, rotates the first rotating ring 7 to thread the first threaded hole 8 with the first threaded column 3. After the first rotating ring 7 is installed, the person rotates the rotating column 17 to thread the threaded end of the rotating column 17 with the second threaded hole 15. At this time, the second rotating ring 16 rotates in the second rotating hole 14 and moves upward. When several rotating columns 17 are installed, the person rotates the first threaded ring 9 Align with the first threaded column 3 and rotate the first threaded ring 9 so that the first threaded ring 9 is threadedly connected to the first threaded column 3. After the first threaded ring 9 is installed, place the base 13 on the ground so that the bottom surface of the base 13 contacts the ground. At this time, the personnel pull the pull rod 23 outward to move the plug column 22 out of the corresponding socket 20 and the limit hole 21. The pull rod 23 drives the tension spring 24 to stretch outward. When the plug column 22 is moved out of the socket 20 and the limit hole 21, pull the protective cover 18 upward to remove the protective cover 18. At this time, release the pull rod 23, and the tension spring 24 rebounds to drive the plug column 22 to be inserted into the corresponding socket 20. At this time, the personnel can use the calibration instrument body 2 for farmland calibration.

[0036] When the personnel have finished using it, they first pull the pull rod 23 outwards to make the plug column 22 move out of the corresponding socket 20, and the pull rod 23 drives the tension spring 24 to stretch outwards. When the plug column 22 is moved out of the socket 20, the protective cover 18 is lowered downwards so that the protective cover 18 is engaged into the engaging groove 19. At this time, the pull rod 23 is released, and the tension spring 24 rebounds and drives the plug column 22 to be inserted into the corresponding socket 20 and the limiting hole 21, thereby limiting the protective cover 18. When the protective cover 18 is installed, the personnel rotates the rotating column 17 so that the threaded end of the rotating column 17 is out of the second threaded hole 15, and then rotates the first threaded ring 9 and removes the first threaded ring 9 from the first threaded column 3. At this time, the personnel can first place the load-bearing plate 1, and then adjust the telescopic rod 10 to a length that is convenient for storage, and rotate the telescopic rod 10 so that the second threaded column 11 is rotated out of the second threaded ring 12. At this time, the personnel can store each component separately, which is convenient for personnel to move and carry the device.
