[0023] Please see Figures 1-4In this embodiment of the present invention, a foldable circular rice and wheat yield measurement sampling device includes a fixed tube 1, a top plate 2 installed at the upper end of the fixed tube 1, the top plate 2 being perpendicular to the fixed tube 1, a bubble level 3 installed at the upper end of the top plate 2 to facilitate the worker's adjustment of the top plate 2 to a horizontal state, a plurality of manually telescopic rods 4 arranged in a circular array around the fixed tube 1 at the lower end of the top plate 2, the upper end of the manually telescopic rods 4 being rotatably connected to the lower end of the top plate 2 by a hinge, a spike 12 installed at the lower end of the manually telescopic rods 4 for inserting into the ground to support and fix the manually telescopic rods 4 and the top plate 2, a folding and storage mechanism for folding the manually telescopic rods 4 provided on the fixed tube 1 and the manually telescopic rods 4, and a sampling mechanism for circular harvesting and sampling of rice and wheat provided at the lower end of the fixed tube 1.

[0024] The sampling mechanism includes a housing 14 and an electric hedge trimmer 8. The upper center of the housing 14 is installed at the lower end of the fixing tube 1. A battery 15 is installed on the top of the housing 14, and a motor 16 is installed at the lower end of the battery 15. The output shaft of the motor 16 is on the same vertical line as the fixing tube 1. The output end of the motor 16 passes through the bottom of the housing 14 and is installed with a fixing frame 13 for fixing the electric hedge trimmer 8. An opening 9 is opened on the side wall of the fixing frame 13 away from the open end to facilitate the passage of the harvesting blade of the electric hedge trimmer 8. The output end of the motor 16 is installed directly above the opening 9. The circular area swept by the harvesting blade of the electric hedge trimmer 8 is 1.1 square meters.

[0025] The electric hedge trimmer 8 uses existing technology and is powered by a battery. The drive housing of the electric hedge trimmer 8 is designed as a cuboid that can move along the inner wall of the fixed frame 13. An internally threaded fixing cylinder 18 is installed on the side wall of the fixed frame 13. The inner wall of the internally threaded fixing cylinder 18 is connected by a fastening bolt 11 for fixing the drive housing of the electric hedge trimmer 8 inside the fixed frame 13 through a threaded rotation.

[0026] A fixing post 17 is installed at the lower end of the fixing frame 13. A fixing rod 10 for supporting the fixing frame 13 is rotatably connected to the side wall of the fixing post 17. The fixing rod 10 and the fixing tube 1 are on the same vertical line.

[0027] Before use, pass the harvesting blade of the electric hedge trimmer 8 through the opening 9 and move the driver of the electric hedge trimmer 8 into the fixed frame 13. Then turn the fastening bolt 11. Under the action of the thread, the fastening bolt 11 abuts against the driver housing of the electric hedge trimmer 8, thereby fixing the electric hedge trimmer 8 inside the fixed frame 13.

[0028] When in use, insert the fixing rod 10 into the ground, then start the motor 16. The output end of the motor 16 drives the fixing frame 13 to rotate, and the fixing frame 13 drives the electric hedge trimmer 8 to rotate, so that the electric hedge trimmer 8 can perform circular harvesting and sampling of rice and wheat.

[0029] The folding and storage mechanism includes a sleeve 7, which slides on the side wall of the fixed tube 1. The upper end of the side wall of the sleeve 7 is rotatably connected to a swing rod 5 corresponding to the manual telescopic rod 4 via a hinge. The end of the swing rod 5 away from the sleeve 7 is rotatably connected to the side wall of the manual telescopic rod 4 via a hinge. A stop block 6 for blocking and limiting the sleeve 7 is installed on the side wall of the fixed tube 1 above the sleeve 7. Fixing components for fixing the sleeve 7 to the side wall of the fixed tube 1 after the manual telescopic rod 4 is unfolded are provided on the fixed tube 1 and the sleeve 7.

[0030] The fixing assembly includes a pin 20. A first pin hole 19 is provided at the lower end of the side wall of the sleeve 7. A second pin hole 21 is provided on the side wall of the fixing tube 1 below the stop block 6. When the upper end of the sleeve 7 moves to the lower end of the stop block 6, the first pin hole 19 and the second pin hole 21 are aligned. The pin 20 is slidably connected to the inner wall of the second pin hole 21. A spring piece 22 for pushing the pin 20 outward from the fixing tube 1 is installed on the inner wall of the fixing tube 1.

[0031] When the manual telescopic rod 4 is extended, the operator moves the sleeve 7 upward and then presses the pin 20 so that the sleeve 7 can fit onto the pin 20. At this time, the pin 20 presses the spring piece 22, causing the spring piece 22 to deform. When the first pin hole 19 is aligned with the second pin hole 21, under the action of the elastic force, the spring piece 22 pushes the pin 20 to insert into the second pin hole 21 and the first pin hole 19, fixing the sleeve 7 to the side wall of the fixed tube 1. At the same time, the sleeve 7 drives the swing rod 5 to swing, and the swing rod 5 pushes the manual telescopic rod 4 to swing and extend. Then, the spike 12 at the lower end of the manual telescopic rod 4 is inserted into the ground.

[0032] When retracting the manual telescopic rod 4, the operator moves the sleeve 7 downwards while pressing the pin 20 so that the sleeve 7 can fit onto the pin 20. At this time, the pin 20 presses the spring 22, causing the spring 22 to deform. When the sleeve 7 is disengaged from the pin 20, under the action of the elastic force, the spring 22 pushes the pin 20 out of the fixed tube 1. At the same time, the sleeve 7 drives the swing rod 5 to swing, and the swing rod 5 pulls the manual telescopic rod 4 to swing and retract, realizing the folding and storage of the manual telescopic rod 4.

[0033] Working principle of a foldable circular rice and wheat yield measurement sampling device:

[0034] When in use, the harvesting blade of the electric hedge trimmer 8 is passed through the opening 9, and the driver of the electric hedge trimmer 8 is moved into the fixed frame 13. Then, the fastening bolt 11 is turned. Under the action of the thread, the fastening bolt 11 abuts against the driver housing of the electric hedge trimmer 8, thereby fixing the electric hedge trimmer 8 inside the fixed frame 13.

[0035] Then, the worker moves the sleeve 7 upward and presses the pin 20 so that the sleeve 7 can fit onto the pin 20. At this time, the pin 20 presses the spring 22, causing the spring 22 to deform. When the first pin hole 19 is aligned with the second pin hole 21, under the action of the elastic force, the spring 22 pushes the pin 20 to insert into the second pin hole 21 and the first pin hole 19, fixing the sleeve 7 to the side wall of the fixed pipe 1. At the same time, the sleeve 7 drives the swing rod 5 to swing, and the swing rod 5 pushes the manual telescopic rod 4 to swing and unfold. Then, the spike 12 at the lower end of the manual telescopic rod 4 and the fixed rod 10 are inserted into the ground, and the top plate 2 is adjusted to a horizontal state by observing the bubble level 3.

[0036] Then, start the motor 16 and the electric hedge trimmer 8. The output end of the motor 16 drives the fixed frame 13 to rotate, and the fixed frame 13 drives the electric hedge trimmer 8 to rotate, so that the electric hedge trimmer 8 can perform circular harvesting and sampling of rice and wheat. The circular area harvested by the harvesting blade of the electric hedge trimmer 8 is 1.1 square meters.

[0037] After harvesting and sampling are completed, loosen the fastening bolts 11 and remove the electric hedge trimmer 8 from the fixed frame 13. Then, remove the spikes 12 and the fixing rod 10 from the ground. Then, the worker moves the sleeve 7 downward while pressing the pin 20 so that the sleeve 7 can fit on the pin 20. At this time, the pin 20 presses the spring 22, causing the spring 22 to deform. When the sleeve 7 is separated from the pin 20, under the action of the elastic force, the spring 22 pushes the pin 20 out of the fixed tube 1. At the same time, the sleeve 7 drives the swing rod 5 to swing, and the swing rod 5 pulls the manual telescopic rod 4 to swing and retract, realizing the folding and storage of the manual telescopic rod 4.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
