[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] like Figure 1-4 As shown, the device includes: a housing 2, with an electric heating wire 21 inside; a motor 1 fixedly connected to the outer surface of the housing 2; a rotating shaft 23 fixedly connected to the output end of the motor 1; a hot air duct 28 fixedly connected to the outer surface of the rotating shaft 23; and an air outlet 27 on the surface of the hot air duct 28. A hot air blower 3 has an air supply duct 26 fixedly connected to its output end; a rotating shaft 29 movably connected to the outer surface of the air supply duct 26; a hot air duct 28 fixedly connected to the inner surface of the rotating shaft 29; a scraper 22 fixedly connected to the outer surface of the rotating shaft 23; and a rotating shaft 29 fixedly connected to the outer surface of the scraper 22. The scraper 22 and the housing 2 are slidably connected. A support plate 4 is fixedly connected to the lower surface of the hot air blower 3; a support rod 5 is fixedly connected to the lower surface of the support plate 4; and the housing 2 is fixedly connected to the outer surface of the support rod 5.
[0022] Specifically: The heating wire 21 inside the box 2 heats the lower surface of the feed. The hot air blower 3 outputs hot air, which is sent to the hot air pipe 28 through the air supply pipe 26. The hot air pipe 28 heats and dries the surface of the feed inside the box 2 through the air outlet 27. The motor 1 is started, which drives the hot air pipe 28 fixedly connected to the outer surface of the rotating shaft 1 23 to rotate. The hot air pipe 28 is also fixedly connected to the inner surface of the rotating shaft 29, which drives the rotating shaft 29 to rotate synchronously. Since the scraper 22 is fixedly connected to the outer surface of the rotating shaft 1 23 and the rotating shaft 29, and the scraper 22 is slidably connected to the box 2, the scraper 22 rotates synchronously, which makes the feed inside the box 2 roll and move, so that the feed is heated evenly and the drying effect is guaranteed. After the feed is dried and discharged from the box 2, clean water is added inside, and the motor 1 is started, which drives the scraper 22 to clean the inner wall of the box 2.
[0023] An exhaust device 15 is provided on the outer surface of the housing 2, and a dustproof net 25 is fixedly connected to the output end of the exhaust device 15.
[0024] Specifically: the exhaust device 15 removes moisture from the inside of the chamber 2, ensuring the stability of the internal temperature of the chamber 2 and accelerating the drying efficiency. The dustproof net 25 reduces the cleaning frequency and lowers maintenance costs.
[0025] A feed inlet 14 is fixedly connected to the upper surface of the box body 2. A sealing cover 13 is movably connected to the outer surface of the feed inlet 14. A handle 11 is fixedly connected to the outer surface of the sealing cover 13. An elastic buckle 12 is fixedly connected to the upper surface of the box body 2 and is movably connected to the sealing cover 13. A discharge outlet 6 is fixedly connected to the lower surface of the box body 2. A sliding groove 24 is provided on the surface of the discharge outlet 6. A discharge baffle 7 is slidably connected to the outer surface of the sliding groove 24. A handle 8 is fixedly connected to the outer surface of the discharge baffle 7.
[0026] Specifically: Feed is added into the box 2 through the feed inlet 14. The feed inlet 14 has a sealing cover 13, which is movably connected to the box 2 through an elastic buckle 12. The feed is discharged from the box 2 through the discharge outlet 6. The surface of the discharge outlet 6 is provided with a chute 24, and a discharge baffle 7 is slidably connected to the outer surface of the chute 24. A handle 8 is fixedly connected to the outer surface of the discharge baffle 7 to ensure that the feed does not overflow during the stirring process. After opening the sealing cover 13, the staff adds feed to the inside of the box 2. After drying, the completely dried feed inside is collected through the discharge outlet 6 by opening the discharge baffle 7.
[0027] A support leg 9 is fixedly connected to the lower surface of the housing 2. A base plate 10 is fixedly connected to the lower surface of the support leg 9. A pad 16 is fixedly connected to the lower surface of the base plate 10. A rotating shaft 17 is rotatably connected to the lower surface of the pad 16. A support frame 18 is fixedly connected to the side surface of the rotating shaft 17. A wheel 19 is rotatably connected to the inner surface of the support frame 18. A protective sleeve 20 is fixedly connected to the outer surface of the wheel 19.
[0028] Specifically: Support legs 9 are fixedly connected to the lower surface of the housing 2, and a base plate 10 is fixedly connected to the lower surface of the support legs 9, ensuring the stability of the equipment. A rotating wheel moving structure is set at the bottom of the device. The lower surface of the base plate 10 is rotatably connected to the support frame 18 through a rotating shaft 17. The outer surface of the rotating wheel 19, which is rotatably connected to the inner surface of the support frame 18, is fixedly connected to a protective sleeve 20. When the entire device needs to be moved, the operator can push the device, and the rotating wheel 19 rolls on the ground. At the same time, due to the rotation characteristics of the rotating shaft 17, the device can flexibly change the direction of movement, making it convenient to move between different working positions.
[0029] Working principle: After adding feed through the inlet 14, the sealing cover 13 is closed, the heating wire 21 is activated to heat the inside, and the hot air blower 3 is activated to send hot air through the air supply pipe 26 to the hot air pipe 28. The hot air outlet 27 on the surface of the hot air pipe 28 heats and dries the surface of the feed inside the box 2. At the same time, the motor 1 is activated to drive the scraper 22 to rotate, so that the feed inside the box 2 rolls and moves, so that the feed is heated evenly and the drying effect is guaranteed. At the same time, the exhaust device is activated to discharge the moisture generated by the feed inside during the drying process. When the feed is dried, the discharge baffle 7 is opened and the completely dried feed is collected through the discharge port 6. After collection, the discharge baffle 7 is closed, and clean water is added to the inside of the box 2 through the inlet 14. The motor 1 is activated to drive the scraper 22 to clean the inner wall of the box 2, and the wastewater is discharged through the discharge port 6.
