This helps to maintain a dry environment inside the drying barrel 1 and avoid the accumulation of waste gas and moisture in the exhaust pipe 5, which may hinder the entry of fresh air and thus affect the drying effect.

[0029] Working principle: During use, first install the connecting plate 19, spring 18 and scraper 17 into the inside of the chute 20 on the square rod 11 through the notch 28. Then, clamp the fixing block 21 on one side of the square rod 11. Then, pass the screw 24 through the jack 22 on the fixing rod and screw it into the threaded hole 23 on the square rod 11. Then, insert the clamping plate 30 into the clamping groove 29 inside the fixing frame 27. Then, remove the lid 4 on the feeding hopper 3 of the sleeve barrel 2 and add the fertilizer to be dried into the inside of the drying barrel 1 through the feeding hopper 3. When a certain amount of fertilizer is added to the drying barrel 1, cover the lid 4. When the drying barrel 1 dries the fertilizer, start the first motor 14 and the heating wire 12.

At the same time, through the action of the spring 18, the scraper 17 can always be in contact with the inner wall of the drying barrel 1, which is beneficial to improving the scraping effect. During the process of the drying barrel 1 drying the fertilizer, start the second motor 25. The output end of the second motor 25 drives the exhaust fan 26 to rotate continuously, extracting the waste gas and moisture generated during the drying process from the inside of the drying barrel 1. At the same time, fresh air enters the inside of the drying barrel 1 through the air inlet 6 and is filtered by the dust-proof net 7. This realizes the acceleration of the discharge of gases such as moisture and waste gas generated during the fertilizer drying process, thereby promoting the air circulation between the inside of the drying barrel 1 and the external environment. This helps to maintain a dry environment inside the drying barrel 1 and avoid the accumulation of waste gas and moisture in the exhaust pipe 5, which may hinder the entry of fresh air and thus affect the drying effect. When the drying work is completed, pull out the baffle 15 from the slot 16 on the discharge pipe 8, and the fertilizer in the drying barrel 1 can be discharged from the discharge pipe 8.
