DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 2-3 In order to expose the inside of the corn seeds and improve the accuracy of moisture determination, the crushing mechanism 5 in this embodiment includes a first motor 501, which is fixed to the upper surface of the mounting plate 4. The output shaft of the first motor 501 passes through and extends to the lower side of the mounting plate 4, and is fixed with a rotating rod 502. The output shaft of the first motor 501 drives the rotating rod 502 to rotate. A rotating block 503 is fixed to the other end of the rotating rod 502. The rotating rod 502 drives the rotating block 503 to rotate. A crushing blade 504 is fixed to the outside of the rotating block 503. The rotating block 503 drives the crushing blade 504 to rotate, thereby fully crushing the corn seeds. A connecting groove 505 is opened on the lower surface of the mounting plate 4. A placement box 506 is arranged inside the connecting groove 505 to facilitate the storage of corn seed samples. A fixing component is arranged on the mounting plate 4.

[0025] In this example, the number of crushing blades 504 is no less than two, and they are symmetrically distributed around the central axis of the rotating block 503, so that the corn seeds can be fully crushed. The outer diameter of the placement box 506 is adapted to the outer diameter of the connecting groove 505, and the inner diameter of the placement box 506 is adapted to the inner diameter of the connecting groove 505, preventing the placement box 506 from loosening inside the connecting groove 505.

[0026] It should be noted that the fixing component includes a first mounting groove 507 opened on the outside of the connecting groove 505, a spring 508 is fixed to the left inner wall of the first mounting groove 507, and a clamping block 509 is fixed to the other end of the spring 508. The placement box 506 is placed in the connecting groove 505. When the placement box 506 enters the connecting groove 505, the outer wall of the placement box 506 squeezes the clamping block 509, so that the clamping block 509 enters the first mounting groove 507 and compresses the spring 508. A clamping groove 510 is opened on the outside of the placement box 506. When the clamping groove 510 moves to the clamping block 509, the spring 508 bounces the clamping block 509 into the inside of the clamping groove 510, so that the clamping block 509 supports and fixes the placement box 506 to prevent the placement box 506 from falling. A connecting groove 510 is fixed to the lower surface of the clamping block 509. Block 511, the lower surface of the connecting block 511 passes through and extends to the lower side of the mounting plate 4, the connecting block 511 is toggled, the connecting block 511 drives the card block 509 to move, so that the card block 509 moves to the first mounting groove 507, so that the placement box 506 loses its fixing effect, so that the placement box 506 can be taken out of the connecting groove 505, a sliding opening is opened on the lower surface of the mounting plate 4, the connecting block 511 is located inside the sliding opening, the width of the sliding opening is adapted to the width of the connecting block 511, and the width of the sliding opening is smaller than the width of the card block 509, the number of the first mounting grooves 507 is two, and they are symmetrically distributed with respect to the central axis of the mounting plate 4, the number of the card slots 510 is equal to the number of the card blocks 509, and the positions correspond one to one, so that the placement box 506 is fixed from both sides, thereby improving the stability of the placement box 506.

[0027] See also Figure 4-5 In order to prevent interference from the external environment during the measurement process, the measuring mechanism 6 in this embodiment includes a weighing instrument 601, which is fixed to the upper surface of the placement table 2. The placement box 506 is placed on the weighing instrument 601, and the initial weight at this time is weighed and recorded. A display screen 602 is fixed on the front of the base 1, and a fixing plate 603 is fixed on the upper surface of the base 1. A second mounting groove 604 is opened on the upper surface of the fixing plate 603. A second motor 605 is fixed on the front of the fixing plate 603. The output shaft of the second motor 605 penetrates and extends to the inside of the second mounting groove 604, and a rotating plate 606 is fixed. The output shaft of the second motor 605 drives the rotating plate 606 to rotate. An isolation cover 607 is fixed on the upper surface of the rotating plate 606. The rotating plate 606 drives the isolation cover 607 to rotate, so that the isolation cover 607 covers the weighing instrument 601. An infrared heater 608 is fixed to the right inner wall of the isolation cover 607. The infrared heater 608 performs infrared irradiation on the corn seed fragments inside the placement box 506 to quickly dry the corn seeds. After irradiation for a period of time, the weighing instrument 601 weighs the weight at this time. The data of the two weighings are recorded and displayed on the display screen 602, so that the moisture content of the corn seeds can be determined.

[0028] In this example, the inner diameter of the isolation cover 607 is larger than the outer diameter of the weighing machine 601, so that the isolation cover 607 can prevent external interference with the measurement work without affecting the weighing data of the weighing machine 601. The outer diameter of the infrared heater 608 is compatible with the inner diameter of the placement box 506. The infrared heater 608 can be aimed at the placement box 506 for heating, thereby improving the drying efficiency.

[0029] The working principle of the above embodiment is:

[0030] (1) First, a portion of corn seed samples is placed in the placement box 506, and then the placement box 506 is placed in the connecting groove 505. When the placement box 506 enters the connecting groove 505, the outer wall of the placement box 506 squeezes the block 509, so that the block 509 enters the first installation groove 507 and compresses the spring 508. When the groove 510 moves to the block 509, the spring 508 bounces the block 509 into the groove 510, so that the block 509 supports and fixes the placement box 506 to prevent the placement box 506 from falling. At this time, the first motor 501 is turned on, and the output shaft of the first motor 501 drives the rotating rod 502 to rotate, the rotating rod 502 drives the rotating block 503 to rotate, and the rotating block 503 drives the crushing blade 504 to rotate, thereby fully crushing the corn seeds.

[0031] (2) After the corn seeds are crushed, the connecting block 511 is moved, and the connecting block 511 drives the clamping block 509 to move to the first mounting groove 507, so that the placement box 506 loses its fixing effect, so that the placement box 506 can be taken out of the connecting groove 505. After the placement box 506 is taken out, the placement box 506 is placed on the weighing instrument 601, and the weight at this time is weighed and recorded. Then, the second motor 605 is turned on, and the output shaft of the second motor 605 drives the rotating plate 606 to rotate, and the rotating plate 606 drives the isolation cover 607 to rotate, so that the isolation cover 607 covers the weighing instrument 601. Then, the infrared heater 608 is turned on, and the infrared heater 608 performs infrared irradiation on the corn seed fragments inside the placement box 506, so that the corn seeds are quickly dried. After irradiation for a period of time, the weighing instrument 601 weighs the weight at this time, and the data of the two weighings are recorded and displayed on the display screen 602, so that the moisture content of the corn seeds can be measured.
