[0033] Please see attached Figure 1 In a preferred embodiment, a hydraulic telescopic rod 5 is vertically fixedly installed on one side of the top of the base 14, a connecting plate 4 is fixedly installed on the telescopic end of the hydraulic telescopic rod 5, and the other end of the connecting plate 4 is welded to the side of the movable sleeve 6.

[0034] The hydraulic telescopic rod 5 is started to drive the moving sleeve 6 to rise through the connecting plate 4, thereby driving the mounting plate 1 to rise through the moving sleeve 6.

[0035] Please see attached Figure 1 , 4 And 5, in a preferred embodiment, the second scale 9 and the placement groove 19 are both provided in plurality, and the second scale 9 and the placement groove 19 are adapted to each other.

[0036] Please see attached Figure 1 , 4 And 5, in a preferred embodiment, the fixed structure includes a first magnet 11, a second magnet 12 and a third magnet 20, and there are multiple first magnets 11 and second magnets 12, and one end of each of the multiple second rulers 9 is welded with an insert 10.

[0037] Please see attached Figure 1 , 4 In a preferred embodiment, the plurality of first magnets 11 are respectively bonded to one side of the plurality of plug-in blocks 10, and the plurality of second magnets 12 are respectively bonded to one end inside the plurality of placement slots 19, and the first magnets 11 and the second magnets 12 are magnetically attracted to each other.

[0038] Please see attached Figure 1 , 4 And 5, in a preferred embodiment, a slot 2 is provided at the top of the first ruler 3 and the multiple second rulers 9, the slot 2 and the plug 10 are adapted to each other, a third magnet 20 is bonded to the bottom of the slot 2, and the first magnet 11 and the third magnet 20 are magnetically attracted to each other.

[0039] When the device is not in use, multiple second rulers 9 are placed in multiple placement grooves 19 respectively, and the first magnet 11 and the second magnet 12 attract each other to fix the second ruler 9 tightly in the placement groove 19. When measurement is needed, the second ruler 9 is taken out from the placement groove 19, and then the plug block 10 is inserted into the slot 2 on the first ruler 3. The first magnet 11 and the third magnet 20 attract each other to fix the second ruler 9 tightly above the first ruler 3, and other second rulers 9 are fixed on the previous second ruler 9 in turn. The number of second rulers 9 can be selected according to the plant height to be measured, thereby increasing the height of the ruler, which is convenient for measuring the height of taller plants, and the second ruler 9 can be disassembled and placed on the base 14 when not measuring, which reduces the height of the device, reduces the volume, and is convenient for movement and carrying.

[0040] From the above description, it can be seen that the above embodiment of the utility model achieves the following technical effects: when the device is not in use, the plurality of second scales 9 are respectively placed in the plurality of placement grooves 19, and the first magnet 11 and the second magnet 12 attract each other to fix the second scales 9 tightly in the placement groove 19, thereby reducing the height and volume of the device, and facilitating movement and carrying;

[0041] When measurement is required, the base 14 is fixed on the ground next to the plant using four pointed cones 16 to keep the base 14 horizontal. When measurement is required, the second ruler 9 is taken out from the placement slot 19, and the insert block 10 is inserted into the slot 2 on the first ruler 3. The first magnet 11 and the third magnet 20 attract each other to fix the second ruler 9 tightly above the first ruler 3, and other second rulers 9 are fixed on the previous second ruler 9 in sequence. The number of second rulers 9 can be selected according to the plant height to be measured, thereby increasing the height of the ruler, which is convenient for measuring the height of taller plants.

[0042] During measurement, the hydraulic telescopic rod 5 is started to drive the movable sleeve 6 to rise through the connecting plate 4, thereby driving the mounting plate 1 to rise through the movable sleeve 6, and the mounting plate 1 drives the infrared detector 17, the distance sensor 18 and the camera 7 to rise together, and at the same time, the infrared detector 17 is started to detect the presence of the plant using the infrared detector 17. When the infrared detector 17 cannot detect the presence of the plant, it means that the infrared detector 17 has just passed over the plant and is directly above the plant. At this time, the controller 13 starts the distance sensor 18 to monitor the distance between it and the base 14, and starts the camera 7 to shoot the height marking line where the movable sleeve 6 is located on the first scale 3 or the second scale 9. The data monitored by the distance sensor 18 and the marking line shot by the camera 7 are transmitted to the controller 13, and the controller 13 processes and converts them into height data for display, thereby measuring the height of the plant, without manual measurement, and the measurement is more convenient and quick. The height of the plant is measured in two different ways: the distance sensor 18 monitors the height and the camera 7 shoots the height marking line, which increases the measurement method, reduces the error of the measurement result, and makes the measurement result more accurate.
