[0002] Feed is a general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed raw materials such as corn contain a lot of water. If not handled in time, the water will cause the feed to become damp and moldy, thus affecting the hygiene and quality of the feed, and also reducing the nutritional value of the feed, affecting the taste and digestion of the feed. At the same time, the drying process can stimulate the enzymes in the feed, making the nutrients in it easier to digest and absorb.

[0027] Working principle: When the dryer is used, first adjust the position of the tensioning pulley 518 through the screening mechanism 5 to tighten the screening belt 501 to ensure the screening efficiency of the screening mechanism 5, then open the feed door 1001 to add the feed into the dryer, and then start the stirring mechanism 6 through the control box 1. The stirring mechanism 6 stirs and breaks up the feed in the dryer to prevent the feed from agglomerating and affecting the drying effect. The stirring mechanism 6 drives the screening mechanism 5 to screen the feed entering the dryer to prevent impurities and dirt in the feed from entering the dryer. The stirring mechanism 6 drives the toggling mechanism 9 to toggle the feed entering the dryer to prevent the moisture-containing feed from sticking and blocking the feed port 10. Then start the rolling mechanism 7 to transport the feed entering the dryer inward so that the feed is fully dried in the dryer. After the feed is filled, close the feed door 1. 001, and then set the temperature parameters of the heating wire 803 of the hot air mechanism 8 through the control box 1, start the fan 804 through the control box 1, suck in the external air through the middle space of the isolation cabin 13 and blow the heated air into the dryer. When the temperature in the dryer rises, the air expands and the pressure in the dryer increases. The exhaust valve 4 discharges the air in the dryer to balance the internal pressure of the dryer to prevent the internal temperature of the dryer from exceeding the set standard and burn the feed, thereby ensuring the quality and drying effect of the feed. When the feed in the dryer is dried, open the discharge door 1101, and operate the rolling mechanism 7 to reverse through the control box 1 to transport the dried feed to the discharge port 11. The stirring mechanism 6 drives the toggle mechanism 9 to toggle the dried feed outward. After the dried feed is taken out, close the discharge door 1101, and the next batch of feed can be dried.

[0028] When the position of the tensioning pulley 518 is adjusted by the screening mechanism 5, the two unlocking columns 515 are pressed inward, and the two unlocking columns 515 move toward each other, driving the two linkage plates 514 to move toward each other, and the two linkage plates 514 move toward each other, driving the two locking blocks 513 to move toward each other, and the two linkage plates 514 and the locking blocks 513 move toward each other to compress the locking spring 516, and the two locking blocks 513 move toward each other and disengage from the tooth grooves of the tensioning frame 510. The locking block 513 releases the locking of the tensioning column 512 by the tensioning frame 510, pulls the tensioning column 512 to slide to one side, and the tensioning column 512 slides to one side to stretch the tensioning spring 511, and the tensioning column 512 slides to one side to drive the driven shaft 517 to slide to one side, and the driven shaft 517 slides to one side to drive the tensioning pulley 518 Sliding to one side, the tensioning pulley 518 slides to one side and contacts the screening belt 501. At this time, the unlocking column 515 is released, and the locking spring 516 releases the pressure to push the two linkage plates 514 and the locking block 513 to move in the opposite direction. The two locking blocks 513 move in the opposite direction and contact the teeth of the tensioning frame 510. The tensioning frame 510 is locked to the tensioning column 512 again through the locking block 513. At this time, the position of the tensioning column 512 is locked, and the tensioning pulley 518 tightens the screening belt 501. When the screening belt 501 needs to be replaced, the two unlocking columns 515 are pressed inwardly to release the locking block 513 from the teeth of the tensioning frame 510. The tensioning spring 511 contracts and pulls the tensioning column 512 to slide to the other side, and the screening belt 501 can be replaced.

The reverse gear 909 rotates to drive the reverse shaft 910 to rotate. The reverse shaft 910 rotates to drive the reverse plate 911 to rotate with the reverse shaft 910 as the center. The active plate 907 and the reverse plate 911 rotate in opposite directions. After the cam 505 is out of contact with the toggle column 901, the reset spring 903 pushes the toggle rack 902 to reset. The reset of the toggle rack 902 drives the active plate 907 and the reverse plate 911 to rotate in the opposite directions. The repeated rotation of the active plate 907 and the reverse plate 911 drives the feed into the dryer to prevent the moisture-containing feed from sticking and blocking the feed inlet 10.

[0032] When the rolling mechanism 7 is started to transport the feed in the dryer, the rolling motor 705 is started, and the output end of the rolling motor 705 drives the rolling gear 704 to rotate, and the rolling gear 704 is meshed and connected with the reduction gear 703.

When discharging is required, the rolling motor 705 can be rotated in the opposite direction, and the rotation of the cylinder 708 facilitates the feeding and discharging of the dryer, so that the feed can be fully dried in the dryer.

[0033] When the exhaust valve 4 discharges the air in the dryer to balance the internal pressure of the dryer, the air in the dryer is filtered by the filter plate 402 and then pushes the valve 403 to rotate with the rotating shaft at the end as the center. The valve 403 rotates with the rotating shaft at the end as the center to compress the limit spring 405. When the air pressure inside the dryer is reduced, the limit spring 405 pushes the valve 403 to reset. The valve 403 is reset to close the dryer to prevent the internal temperature of the dryer from exceeding the set standard and burning the feed, thereby ensuring the quality of the feed and the drying effect.
