The device includes: a camera assembly for acquiring canopy time-series images of winter wheat seedlings; a computer for predicting winter wheat yield using a target winter wheat yield prediction model and the canopy time-series images of winter wheat seedlings; the target winter wheat yield prediction model is used to predict winter wheat yield; the camera assembly is connected to the computer; a vertical pole and a horizontal arm, the bottom of the vertical pole is fixed to the ground, the top of the vertical pole is connected to the first end of the horizontal arm; the second end of the horizontal arm is connected to the camera assembly.

[0004] However, the implementation of the relevant technology revealed the following problems with the above-mentioned technical solution: During use, the prediction device uses a vertical pole and a horizontal arm to support the camera assembly for image comparison of winter wheat. However, when retracting the vertical pole and horizontal arm, the excessive length of the vertical pole makes proper placement difficult, and the perpendicular relationship between the horizontal arm and the vertical pole results in a large space requirement when retracting the prediction device, making it prone to bending due to contact with walls or other objects when moving the device. Therefore, a portable wheat yield measurement device is proposed to solve these problems. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Implementation

[0024] Please see Figure 1 -5, A portable wheat yield measuring device, comprising: a vertical pole 1 and a horizontal arm 2;

[0025] An extension rod 3 is slidably installed inside the vertical pole 1. A positioning hole 4 is opened inside the vertical pole 1 and the extension rod 3. A bolt 5 is slidably installed inside the positioning hole 4. A nut 6 is installed on the external thread of the bolt 5.

[0026] A hinge 7 is fixedly installed inside the extension rod 3, a rotating shaft 8 is rotatably installed inside the extension rod 3, a support plate 9 is fixedly installed outside the rotating shaft 8, and a baffle 10 is fixedly installed at the bottom of the horizontal arm 2.

[0027] The technical solution provided in this embodiment is as follows: In use, the wheat yield measuring device is first inserted into the bottom surface and fixed by the vertical cone 15. Then, the camera 18 takes pictures of the wheat in the field and transmits them to the computer 11 through the wire. The computer 11 then compares the current wheat picture with the previous picture and calculates the wheat yield. When it is necessary to retract the wheat yield measuring device, the vertical cone 15 is first pulled out and the wheat yield measuring device is placed flat on the ground. Then, the horizontal arm 2 is flipped backward by the hinge 7 so that the horizontal arm 2 is located inside the extension rod 3. Then, the camera 18 is removed by tightening the fastener 16 and placed separately to prevent damage to the camera 18. Then, the nut 6 is unscrewed and the bolt 5 is pulled out from the inside of the positioning hole 4. Then, the extension rod 3 is slid down into the inside of the vertical pole 1. Then, the bolt 5 is inserted into the positioning hole 4 opened inside the vertical pole 1, passing through the positioning hole 4 opened near the top of the extension rod 3 to fix the extension rod 3, so that the wheat yield measuring device is retracted to reduce the space occupied. Then, the wheat yield measuring device can be lifted by hand by the handle 12 for movement.

[0028] Furthermore, a computer 11 is fixedly installed on one side of the vertical pole 1, and a handle 12 is fixedly installed on one side of the vertical pole 1.

[0029] Specifically, by fixing a handle 12 to one side of the vertical pole 1, the wheat yield measuring device can be lifted by the handle 12 when it is being retracted, thereby moving the wheat yield measuring device.

[0030] Furthermore, a fixing member 13 is fixedly installed at the bottom of the vertical pole 1. The fixing member 13 has a threaded hole 14 inside, and a vertical cone 15 is installed inside the threaded hole 14.

[0031] Specifically, by threading the vertical cone 15 inside the threaded hole 14, the wheat yield measuring device can be inserted into the ground through the vertical cone 15, thereby enabling the wheat yield measuring device to measure the wheat yield.

[0032] Furthermore, a fastener 16 is installed inside the horizontal arm 2 via internal threads, and a fixing plate 17 is movably set at the bottom of the horizontal arm 2 via the fastener 16. A camera 18 is fixedly installed at the bottom of the fixing plate 17.

[0033] Specifically, by using the fixing plate 17 and fasteners 16 to mount the camera 18 at the bottom of the horizontal arm 2, the camera 18 can capture a more comprehensive view of the wheat, thereby making the yield measurement more accurate.

[0034] Furthermore, there are eight positioning holes 4 inside the extension rod 3, and the eight positioning holes 4 are divided into two groups inside the extension rod 3.

[0035] Specifically, by dividing the eight positioning holes 4 into two groups and opening them inside the extension rod 3, the extension rod 3 can be fixed inside the vertical pole 1 by bolts 5 and nuts 6 when it is retracted, making it easy to retract the wheat yield measuring device.

[0036] Furthermore, the camera 18 has internal wiring, with the other end of the wiring connected to the computer 11.

[0037] Specifically, by connecting the camera 18 and the computer 11 with a wire, the photos of wheat in the field taken by the camera 18 can be transmitted to the computer 11 through the wire, so that the computer 11 can measure the wheat yield.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
