[0031] In use, after the furnace charge is tumbled by the material shaking mechanism 4, the furnace charge falls on the upper surface of the discharging belt 102 through the first conveying belt 104, and is continuously transported forward, so that the furnace charge is sent out of the drying mechanism 1 through the feeding plate 103, the function of drying the furnace charge is completed, the positions of the discharging belt 102 and the hot air pipe 107 are separated by the partition plate 105, the heat inside the drying mechanism 1 is increased by the hot air pipe 107, and the furnace charge is quickly dried, after the furnace charge is tumbled and spread in the material shaking mechanism 4, gradually falls and contacts the fixed inclined plate 503 in the anti-scattering mechanism 5, so that the furnace charge is ensured to fall on the surface of the first conveying belt 104 and enter the secondary adding area, the drying of the furnace charge is ensured, and then the furnace charge is sent out of the drying mechanism 1, the two anti-scattering plates 502 avoid the furnace charge from scattering to other areas inside the hot air drying frame 101, and cause the loss of the furnace charge.

[0032] Referring to Figure 1 and Figure 2As shown, the sealing mechanism 2 comprises a front guard 201, three fixed bolts 202 are fixedly arranged on the front side of the front guard 201, a sliding groove 205 is formed on the front side of the front guard 201, a limiting rod 203 is fixedly arranged on the inner top surface of the sliding groove 205, a limiting lock 204 is fixedly arranged on the lower front side of the front guard 201, and a closing plate 206 is longitudinally and slidably arranged on the inner side of the sliding groove 205.

[0033] In the above embodiment, when the furnace charge is dried and needs to be taken out, the closing plate 206 is slid upward in the sliding groove 205 to provide space for the feeding plate 103 to discharge, then the handle on the front side of the closing plate 206 is limited by the limiting lock 204 to continuously provide space for the feeding plate 103 to discharge, until the furnace charge is taken out. When the drying mechanism 1 needs to be repaired, the fixed bolts 202 are removed to disassemble the front guard 201, which is convenient for subsequent maintenance.

[0034] As shown in Figure 5 and Figure 6 As shown, the two rotating shafts 402 and one rotating rod 408 of the material shaking mechanism 4 are provided with a second transmission belt 404 between the two rotating shafts 402, and the shaft bodies of the two rotating shafts 402 are rotatably provided with inclined clamping plates 401 on the front and back sides, the upper sides of the opposite sides of the two inclined clamping plates 401 are fixedly provided with extension plates 405, the two extension plates 405 are higher than the second transmission belt 404, the front side of the shaft body of one of the two rotating shafts 402 is fixedly provided with a push rod 403, the front and back sides of the shaft body of the other of the two rotating shafts 402 are rotatably provided with rotary clamping plates 406, the bottom sides of the two rotary clamping plates 406 are fixedly provided with U-shaped connecting plates 407, the top sides of the U-shaped connecting plates 407 are fixedly provided with slotted blocks 409, the rod body of the rotating rod 408 is provided with an L-shaped connecting flap 411, one side of the L-shaped connecting flap 411 penetrates the inner side of the slotted block 409, and the two sides of the L-shaped connecting flap 411 penetrating the slotted block 409 are fixedly provided with limiting plates 410.

[0035] In use, the second transmission belt 404 is supported by two rotating shafts 402, one of which is connected to the rear side of the inner wall of the drying mechanism 1 and serves as a driving shaft, and the other rotating shaft 402 is arc-shaped and slides in the interior of the drying mechanism 1 to provide a movable space for the rotation of the second transmission belt 404. A push rod 403 is fixed to the rear side of the shaft body of the driving shaft 402 and rotates with the driving shaft 402. The push rod 403 pushes the L-shaped connecting flap 411 downward, and the middle part of the L-shaped connecting flap 411 is fixed to the two sides of the shaft body of the rotating rod 408. When one side of the L-shaped connecting flap 411 is pushed downward, the other side is pushed upward. Similarly, after the push rod 403 pushes the L-shaped connecting flap 411 downward, the other side of the L-shaped connecting flap 411 is pushed upward. The part of the L-shaped connecting flap 411 extending into the slot block 409 and fixed inside the slot block 409 moves upward with the slot block 409 and the U-shaped connecting plate 407. The two rotating clamping plates 406 clamped on the front and rear sides of the slidable rotating shaft 402 make the slidable rotating shaft 402 move upward, and the second transmission belt 404 moves upward, which makes the furnace charge on the top side of the second transmission belt 404 tumble and spread out, increases the contact area between the furnace charge and the hot gas in the interior of the drying mechanism 1, and increases the drying efficiency of the furnace charge.

[0036] With the above structure, after the furnace charge to be dried is fed into the second transmission belt 404 of the shaking mechanism 4 through the feeding port 3, the hot gas pipe 107 on the bottom surface of the drying mechanism 1 is started to heat the interior of the hot air drying frame 101, and the two rotating shafts 402 are started to rotate with the second transmission belt 404. When the two rotating shafts 402 start to rotate, the push rod 403 fixed to the rear side of the shaft body of the rotating shaft 402 away from the anti-scattering mechanism 5 rotates with the rotating shaft 402. When the push rod 403 rotates to the downward position, it pushes the L-shaped connecting flap 411 to make one side of the L-shaped connecting flap 411 rotate downward and drive the rotating rod 408. The other side of the L-shaped connecting flap 411 is pushed upward, and the part of the L-shaped connecting flap 411 fixed inside the slot block 409 drives the U-shaped connecting plate 407 on the bottom side of the entire slot block 409 to move upward with the rotating shaft 402 close to the anti-scattering mechanism 5 through the rotating clamping plates 406 fixed on the front and rear sides above. The U-shaped connecting plate 407 makes one end of the entire second transmission belt 404 move upward. After the push rod 403 and the L-shaped connecting flap 411 are separated, the side close to the anti-scattering rotating shaft 402 is reset and lowered due to the gravity of the rotating shaft 402 itself. In this process, the furnace charge above the second transmission belt 404 is lifted and falls to form a whole material, which spreads out the furnace charge and increases the contact area between the furnace charge and the hot gas, thereby improving the drying efficiency.

[0037] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
