An image acquisition device 7 is arranged at the bottom of the active block 6. The image acquisition device 7 is an existing commercially available device, which has a camera for acquiring images and a storage module, and is also equipped with an electric power supply. A traction mechanism 8 is arranged on each slider 4. Each traction mechanism 8 is connected to the active block 6 through a traction rope 80. The active block 6 is pulled by the traction mechanism 8 to move longitudinally along the corn experimental field on the traction rope 80. The ear emergence situation and pest and disease images of the corn are acquired at a close distance above the corn by the image acquisition device 7. The detection device has a simple structure, is convenient for disassembly, installation and carrying, and has a large detection range, high speed and high detection efficiency when equipped with a corn monitoring instrument.
[0033] In this embodiment, please refer to Figure 1 , 2 , 3. The active block 6 is horizontally arranged between the two steel wires 5. Four groups of fixed pulleys 61 are symmetrically arranged on both sides of the active block 6. The mounting seat 611 of each fixed pulley 61 is fixedly connected to the side wall of the active block 6. The fixed pulleys 61 on both sides of the active block 6 are restricted in the middle by the two steel wires 5.

Since the active block 6 only contacts the two steel wires 5 through the rolling surface of the rollers of the four groups of fixed pulleys 61, during the rotation of the rollers of the four groups of fixed pulleys 61, it can move along the guiding of the two steel wires 5. By installing the image acquisition device 7 at the bottom of the active block 6, the image acquisition window of the image acquisition device 7 faces downwards and is aligned with the corn in the corn experimental field. During the movement of the active block 6, the image acquisition device 7 is driven to take close-up shots of the corn ears, branches and leaves, and fruits at the upper end of the corn, and various growth parameters of the corn in the experimental field can be accurately acquired.

One end of the traction rope 80 is wound around the wire winding drum 83, and the other end is fixedly connected to an ear seat 60 provided on the movable block 6. The driving motor 82 drives the wire winding drum 83 to rotate clockwise through its output shaft to wind up the traction rope 80, and rotates counterclockwise to release the traction rope 80. The driving motor 82 is a servo motor, which is powered by a storage battery and its forward and reverse rotations are controlled by a controller.
[0036] In this embodiment, please refer to Figure 1 、 4 , both the first guide rail 2 and the second guide rail 3 are supported and fixed on the upright column 1 through an adjusting seat 9.

[0038] As can be seen from the above technical solutions, during use, first, the two sliders 4 are moved to the same side of the corn test field by the operators at both ends of the corn test field. Then, the driving motor 82 at the head of the test field is controlled by the controller to drive the winding drum 83 to wind up the towing rope 80, and at the same time, the driving motor 82 at the tail of the test field drives the winding drum 83 to release the towing rope 80, so that the image acquisition device 7 on the movable block 6 moves to the head of the test field. At this time, the image acquisition device 7 is located at the initial acquisition position. Then, the driving motor 82 at the head of the test field is controlled by the controller to drive the winding drum 83 to release the towing rope 80, and at the same time, the driving motor 82 at the tail of the test field drives the winding drum 83 to wind up the towing rope 80, so that the image acquisition device 7 on the movable block 6 quickly moves to the tail of the test field, and then stops moving. Next, the two sliders 4 are moved one row spacing to the same side on the first guide rail 2 and the second guide rail 3 by the operators at both ends of the corn test field. Then, the driving motor 82 at the head of the test field is controlled by the controller to drive the winding drum 83 to wind up the towing rope 80, and at the same time, the driving motor 82 at the tail of the test field drives the winding drum 83 to release the towing rope 80, so that the image acquisition device 7 quickly moves to the head of the test field. Then, the above steps are repeated to enable the image acquisition device 7 to collect information on the next row of corn.
