The traction component 3 moves along the guide component 1 under the drive of the power component 2. At the same time, the traction component 3 is connected to the cart 4, and the movement of the cart 4 is driven by the traction component 3 to pull the cart 4 out of the drying box body 5, which effectively reduces the situation where the operator is burned by touching the cart 4 during the transportation of the cart 4. At the same time, there is no need to wait for the cart 4 to cool down in the drying box body 5 before pulling it out, which effectively improves the continuity of the drying operation and improves the production efficiency.

[0045] Among them, Figure 3-4As shown, a guide groove 111 is provided in the middle of the first guide rail 11 along its length direction, and two stoppers 112 are provided on the sidewalls of the guide groove 111, and the two stoppers 112 are respectively located at the two ends of the guide groove 111. In this embodiment, the stopper 112 includes a mounting seat 112a and a rotating portion 112b, the mounting seat 112a is fixedly connected to the sidewall of the guide groove 111, and the rotating portion 112b is rotatably connected to the mounting seat 112a, and the rotating portion 112b can rotate at a limited angle, and the rotating portion 112b abuts against the traction assembly 3 through the rotating portion 112b, thereby limiting the movement of the traction assembly 3.
[0046] During operation, the limit members 112 located at both ends of the guide groove 111 respectively abut against the traction component 3 in sequence, and the movement range of the traction component 3 is limited by the two limit members 112, so that the traction component 3 moves between the two limit members 112 to reduce the collision between the traction component 3 and the guide component 1.

The driving wheel 221 and the driven wheel 222 are connected by the chain 223. At the same time, the chain 223 is also connected to the traction assembly 3 to drive the traction assembly 3 to move on the first guide rail 11, and then the traction assembly 3 is used to pull the cart 4. In this embodiment, the driving member 21 can be selected as a motor, and the driving wheel 221 and the driven wheel 222 can be selected as sprockets.
[0048] like Figure 1 and 5 As shown, in this embodiment, the traction assembly 3 includes a moving seat 31, a traction shaft 32 and a control shaft 33, wherein the moving seat 31 is located on the inner side of the first guide rail 11 and moves along the first guide rail 11, the traction shaft 32 is fixed above the moving seat 31, and the length of the traction shaft 32 is greater than the length of the moving seat 31, and the length of the traction shaft 32 extends toward the direction of the cart 4, and the control shaft 33 is connected to the top of the traction shaft 32, and the control shaft 33 can move relative to the traction shaft 32.
[0049] Among them, Figure 1 , 6As shown in Figures 7 and 8, a towing hook 323, a first connecting member 321 and a second connecting member 322 are provided at one end of the traction shaft 32 close to the cart 4, and a first through hole 331 and a second through hole 332 are provided at the end of the control shaft 33 close to the cart 4.

At the same time, the end of the hook claw 323a is located in the first through hole 331, and the hook claw 323a can rotate around the first connecting member 321 to realize the clamping operation of the towing hook 323. The traction shaft 32 is connected to the cart 4 through the towing hook 323 to realize the towing of the cart 4 by the traction assembly 3. In addition, the second connecting member 322 passes through the second through hole 332 to fix the control shaft 33 on the upper side of the traction shaft 32. At the same time, the control shaft 33 can move along the length direction of the traction shaft 32, and the opening and closing of the towing hook 323 can be controlled by the control shaft 33. In this embodiment, the first connecting member 321 and the second connecting member 322 can be bolts.
[0050] In addition, if Figure 1 and 6 As shown, a U-shaped plate 324 and abutment 325 are further provided at one end of the traction shaft 32 close to the cart 4.

At the same time, a holding rod 333 is also provided on the side of the control shaft 33 away from the towing hook 323. The holding rod 333 is arranged perpendicular to the control shaft 33 to provide a place for holding the control shaft 33, thereby increasing the convenience of operation.
[0053] Working principle: When working, first connect the traction component 3 to the cart 4 in the drying box 5, and transmit the power to the transmission component 22 through the driving member 21. The transmission component 22 drives the traction component 3 to move, and then the traction component 3 is used to pull the cart 4, and the cart 4 loaded with dried materials is pulled out of the drying box 5. When the traction component 3 is disengaged from the cart 4, the transmission component 22, driven by the driving member 21, pulls the empty traction component 3 back to the starting position for the next round of transportation.
