[0002] "A Brief Discussion on the Method for Testing the Moisture and Drying of Corn Seeds" records that the detection and inspection of corn seed moisture is an important part of corn seed production, breeding and storage. As one of the four major indicators of corn seeds, moisture directly affects the quality and vitality of seeds. It also records several methods for testing the moisture of corn seeds. A Chinese patent discloses a corn seed moisture detection device (authorization announcement number CN217786871U). The patent technology discloses a corn seed moisture detection device including a detection platform and a leg supporting the detection platform. The detection platform is fixed with a detection frame, and the detection frame is threaded with a pressure bolt.

The detection platform is equipped with a lifting and lowering bearing device for fixing the corn seed. The utility model discloses a corn seed moisture detection device, which can solve the problem that the existing farmers pinch the embryo to detect the moisture of corn seeds, but the data obtained has large errors due to uneven force control. This patented technology solves the problem that computer moisture meters are the most accurate in measuring the moisture content of corn seeds. However, the instruments are expensive and not suitable for farmers to test at home. Farmers generally use the method of pinching the embryo to detect the moisture content of corn seeds.

[0031] A controller 12 for controlling the corn seed moisture detection mechanism 2 is installed on the side of the detection hand rod 1; the seed corn isolation closed structure 3 includes a reset ring buckle 301, which is fixedly installed on the reset ring buckle 301 of the outer wall of the detection side rod 1 201 and the detection side rod 2 202, and the inside of the reset ring buckle 301 on both sides is movably provided with an isolation arc plate 302, and a vertical rod 303 is fixedly installed on the top of the isolation arc plate 302, and a reset shaft plate 306 is movably sleeved on the outer side of the vertical rod 303;

[0033] Working principle:

[0034] When testing the moisture content of corn seeds in the silo, the testing hand bar 1 can guide the corn seed moisture testing mechanism 2 to penetrate into the silo through the tapered bar 207; then, the operator needs to hold the stretching bar 305 on the right side of the testing hand bar 1 and drive the isolation arc plate 302 to move through the vertical bar 303; the purpose of this step is to expand the corn seed inlet and outlet slot 203 on the second testing side bar 202 so that the seeds can smoothly fall between the inclined top bar 205 and the inclined bottom bar 211;

[0035] When the corn seeds fall into the designated position, the detection handle 1 and the corn seed moisture detection mechanism 2 can be drawn out together; then, the cylinder 1 204 is activated by the controller 12, and the cylinder 1 204 will push the inclined top rod 205 to approach the inclined bottom rod 211, thereby squeezing and crushing the corn seeds between the two; in this process, the moisture in the seeds will flow into the moisture detector 210 through the moisture diversion hole 212 for detection;

[0036] After the detection is completed, the discharge process of the corn seeds is as follows: first, the isolation arc plate 302 on the detection side rod 1 201 is moved to expand the corn seed inlet and outlet slot 203 again; then, the cylinder 209 is started, and the cylinder 209 will push the inclined bottom rod 211 up to the position of the corn seed inlet and outlet slot 203, so that the seeds are discharged smoothly;

[0037] Finally, for maintenance or cleaning, the outer thread 208 can be moved along the inner thread 206 by rotating the tapered rod 207, so that the moisture detector 210 can be disassembled and taken out; after the moisture detector 210 is disassembled and taken out, necessary maintenance and cleaning work is performed on it; this usually includes steps such as cleaning the residue inside the detector, checking the working state of the sensor, and calibrating the detection accuracy; through regular maintenance and cleaning, the accuracy and reliability of the moisture detector 210 can be ensured, thereby providing accurate corn seed moisture content data;

[0038] After completing maintenance and cleaning, reinstall the moisture detector 210 back to its original position; during the installation process, it is necessary to ensure that the tapered rod 207 is tightly connected to the external thread 208 to prevent the moisture detector 210 from loosening or falling off during use.
