[0078] Both the lid opening torque servo 1302 and the lid closing torque servo 1402 can adopt the existing 20kg torque servo.

[0079] In this embodiment, the image acquisition device 11 includes a bottle information acquisition camera 1101 and a seed information acquisition camera 1102. Both the bottle information acquisition camera 1101 and the seed information acquisition camera 1102 are USB cameras.

The empty bottle is then placed on the electronic balance 601 on the weighing platform, and the pushing device 7 pushes the bottle to the bottom of the square funnel 602.

[0102] Step 6: The sealing baffle 1502 extends forward to block the discharge port of the material box 502. The material box 502 vibrates to disperse the accumulated wheat seeds. The image acquisition device 11 then captures images, which are analyzed by the image analysis system in the computing platform to calculate the number, length, and width of the wheat seeds.

[0103] Step 7: After the image acquisition is completed, the material box 502 vibrates to discharge the seeds from the material outlet of the material box 502 and drop them into the square funnel 602. The seeds are then put back into the collection bottle located below the square funnel 602;

[0104] Step 8: After the seeds are loaded, the pushing device 7 continues to push the collection bottle to the starting end of the cover closing conveyor 2. The cover closing conveyor 2 conveys the collection bottle to the cover closing block 1401 to block the collection bottle and stop the collection bottle from being conveyed;

[0105] Step 9: The cover closing screw 801 drives the cover closing rotating jaw 804 and the bottle cap to descend to the mouth of the collection bottle, the cover closing fixed jaw 805 clamps the bottle body of the collection bottle, and the cover closing rotating jaw 804 rotates clockwise to screw on the bottle cap, then the cover closing rotating jaw 804 releases the bottle cap and rises driven by the cover closing screw 801, and the cover closing baffle 1401 rotates to allow the collection bottle to continue moving forward until it reaches the end of the cover closing conveyor 2, and the testing of one variety of wheat seeds is completed.
