[0034] Specifically, when the material completes the predetermined processing flow in the drying process, the connection between the feed bin 20 and the feed wheel 27 will be precisely disconnected. This step is the key to ensure that the material can be smoothly separated from the drying equipment and enter the unloading process. Subsequently, the hydraulic cylinder 208, as a power source, is activated and drives the traction rod 210 to move smoothly and powerfully. Every slight movement of the traction rod 210 pulls the combustion chamber 17 to move synchronously. The movement of the combustion chamber 17 is not isolated, it drives the mounting frame 12 and the slide bar 29 as a whole structure to move synchronously. The slide bar 29 slides in the slide groove 16 like a train sliding on a rail, stably and accurately planning the moving trajectory of the combustion chamber 17; as the distance between the combustion chamber 17 and the cylinder 9 gradually increases, at this time, the heavy equipment jack 201 is activated, and it pushes the arc plate 204 on the right side to slowly lift up with its powerful lifting force; the anti-slip pattern 8 is an important auxiliary element in this process, and its existence greatly increases the friction between the cylinder 9 and the arc plate 204, effectively avoiding the possible falling off of the cylinder 9 during the lifting process, ensuring the entire unloading The safety and stability of the process; as the right curved plate 204 gradually rises, the cylinder 9 begins to slowly tilt to the left; in this process, the rubber plate 203 plays an important role as an elastic element; it can not only withstand the huge pressure generated when the cylinder 9 tilts and undergo corresponding bending deformation, but also can quickly return to its original state when the cylinder 9 is reset through its good elastic recovery performance; this design makes the entire unloading process smoother and more stable; when the cylinder 9 tilts to a certain angle, its left position will accurately slide into the arc groove block 206; this design cleverly utilizes The mechanical principles of physics are used to enable the cylinder 9 to naturally slide to the specified position without external force intervention; at the same time, the ball 205, as a key component for reducing friction, plays an important role in the sliding process of the cylinder 9; they not only greatly reduce the friction between the cylinder 9 and the arc-shaped groove block 206, but also make the sliding process of the cylinder 9 more stable and rapid; finally, the material is smoothly poured out through the discharge hopper 5; the entire unloading process can be completed without manual operation, which greatly saves labor costs and time costs. The model of the servo motor 4 is Parker SMH, the model of the hydraulic cylinder 208 is Single-acting hydraulic cylinder, the model of the jack 201 is Gear Jack, and the model of the burner 15 is Oil Burner.

[0035] Reference Figure 1 , a reinforcing rib 18 is fixedly connected to the inner side of the mounting frame 12, and a stabilizing plate 23 is fixedly connected to the inner wall of the base frame 1;

[0036] Specifically, the reinforcing ribs 18 increase the stability of the mounting frame 12 , and the stabilizing plate 23 increases the stability of the base frame 1 .

[0037] Working principle: When drying the material, open the valve 13 to allow the cold air duct 14 to enter the air, and at the same time, turn on the burner 15 to spray the flame. The flame and the cold air are mixed into hot air and blown to the left, and the material is put into the feed bin 20 through the feed hopper 10. At the same time, turn on the servo motor 4 to drive the fixed rod 22 to rotate with the gear 21. The rotation of the gear 21 is meshed with the teeth 7 to drive the cylinder 9 to rotate. The rotation of the cylinder 9 and the feed wheel 27 rotate synchronously. Through the cooperation between the front plate 24, the scraper 25, the push plate 26 and the rear plate 28, the material in the feed bin 20 is scraped into the cylinder 9, and at the same time, the hot air is blown into the cylinder 9 to dry the material, completing the material drying process;

[0038] After the material is dried, the connection between the feed bin 20 and the feed wheel 27 is disconnected, the hydraulic cylinder 208 is turned on to drive the traction rod 210 to move, the movement of the traction rod 210 pulls the combustion chamber 17 to move synchronously, the movement of the combustion chamber 17 drives the mounting frame 12 and the slide bar 29 to move synchronously, the slide bar 29 slides in the slide groove 16, and the movement trajectory of the combustion chamber 17 is planned, so that the combustion chamber 17 is separated from the cylinder 9, the jack 201 is turned on for lifting, and the right side is pushed The curved plate 204 is lifted, and the anti-slip pattern 8 increases the friction between the cylinder 9 and the curved plate 204 to prevent the cylinder 9 from falling off. After the right curved plate 204 is lifted to a certain height, the cylinder 9 will tilt to the left, and the rubber plate 203 will bend synchronously under the force. At the same time, the cylinder 9 is supported by the two curved plates 204 on the left along the inclined trajectory. The left side of the cylinder 9 slides into the curved groove block 206, and its friction is reduced by the ball bearing 205. At the same time, the material is poured out through the discharge hopper 5.
