[0030] The working principle of the height measuring device for corn seed breeding in the utility model is as follows:

[0031] When the height measuring device for corn seed breeding is used, the transmission motor and the drive motor in the height measuring mechanism are driven to move through the control panel, so that the ray generator can be moved to a suitable position according to the demand, and the growth height of the corn seed seedlings can be measured;

[0032] The ray generator that emits rays will measure the height of the current seeds during the horizontal movement. The more protruding seedlings will block the light. The operator can calibrate and locate the seeds with special development at this time, which is convenient for the subsequent selection of corn seed seedlings. The operator can control the working position, speed and stroke of the ray generator through the control panel to meet the different measurement needs of the seed cultivation stage;

[0033] When the ray generator needs to move horizontally, the transmission motor drives the screw in the screw transmission seat to drive the moving seat to move horizontally, and the moving seat drives the ray generator on the lifting structure to move horizontally;

[0034] When the ray generator needs to be adjusted in height, the driving motor in the lifting structure drives the transmission gear through the connecting rod, so that the transmission gear can drive the lifting shell to move through the gear cooperation, and the lifting shell cooperates with the auxiliary wheel to move vertically;

[0035] When the cultivation tray needs to be taken and placed, the lifting shell in the lifting structure of the height measuring mechanism can be controlled by the control panel to move to the top to prevent the lifting shell from affecting the taking and placing of the cultivation tray;

[0036] The height measurement mechanism can be controlled through the control panel to carry out automated measurement work, which greatly meets the measurement needs of corn seeds at different stages.
