The belt pulley 1 51 is fixedly sleeved on the surface of the rotating shaft of the motor 2 66. The motor 2 66 is fixedly connected to the bottom of the box body 1 through a support. Both ends of the rotating rod 53 are rotatably embedded in the inner wall of the feed hopper 4 through bearings.

[0028] See also Figure 3 and Figure 6There are five vertical rods 61, and they all slide through the bottom of the box body 1. The top of the vertical rod 61 is welded to the bottom of the U-shaped plate 62, and the bottom end of the vertical rod 61 is welded to the top of the connecting plate 64. By setting the vertical rod 61, the U-shaped plate 62 is guided and limited, and can move on the box body 1 at the same time, and the U-shaped plate 62 and the connecting plate 64 are indirectly connected, so that when the connecting plate 64 moves, it can drive the U-shaped plate 62 to move. Both ends of the roller 63 are rotatably connected to the inner wall of the U-shaped plate 62 through a rotating shaft. By setting the roller 63, the force between the U-shaped plate 62 and the grate cooling plate 2 is reduced, and the friction is reduced, so that when the U-shaped plate 62 moves up and down, it can smoothly drive the grate cooling plate 2 to rotate, and the top of the moving frame 65 is welded to the bottom of the connecting plate 64.

The front side of the discharge hopper 7 is fixedly connected to the back side of the U-shaped plate 62 on the rear side through the support plate.

By setting the discharge pipe 34, the raw materials conveyed to the upper part of the inclined tube 31 are discharged into the box body 1, the upper end of the discharge pipe 34 is communicated with the surface of the upper end of the inclined tube 31, and the lower end of the feed hopper 4 is communicated with the surface of the lower end of the inclined tube 31.

[0031] See also Figure 2 and Figure 3The air cooling mechanism 13 includes an L-shaped tube 131. There are five L-shaped tubes 131, and one end of each of the L-shaped tubes 131 is fixedly embedded in the left side of the box body 1. One end of the L-shaped tube 131 located outside the box body 1 is connected with a connecting tube 132. By setting the connecting tube 132, multiple L-shaped tubes 131 are indirectly connected to the air pump 133, so that the gas discharged by the air pump 133 can enter the multiple L-shaped tubes 131. The front side of the left side of the box body 1 is fixedly connected with the air pump 133 through a support. The output end of the air pump 133 is connected to the front end of the connecting tube 132, and one end of the L-shaped tube 131 located in the inner cavity of the box body 1 is connected with an air outlet head 134.

[0032] See also Figure 1 , Figure 3 and Figure 5 The top of the air outlet pipe 8 is fixedly connected with a mesh plate 9 by bolts. By setting the mesh plate 9, the gas discharged from the top of the air outlet pipe 8 is filtered. An L-shaped plate 10 is slidably penetrated on the back of the air outlet pipe 8.

The surface of the rear end of the air outlet pipe 8 is fixedly connected with the electric telescopic rod 12, and the front end of the electric telescopic rod 12 is fixedly connected to the back of the air outlet pipe 8.

[0033] See also Figure 2 The top of the front inner cavity of the box body 1 is rotatably connected to a baffle through a rotating shaft. By setting the baffle, the raw materials discharged from the discharge pipe 34 are shielded and diverted so that they are discharged into the grate cooling plate 2 on the front side. The bottom of the baffle is rotatably connected to a roller through a rotating shaft. By setting the roller, the friction between the baffle and the grate cooling plate 2 is reduced, so that the grate cooling plate 2 can drive the baffle to rotate reciprocatingly when it rotates reciprocatingly.

[0034] When in use, raw materials are added to the feed hopper 4 by controlling the operation of motor 1 32 and motor 2 66. The rotation of the motor 2 66 shaft drives the belt pulley 1 51 and the turntable 67 to rotate. The belt pulley 1 51 drives the belt pulley 2 52, the rotating rod 53 and the paddle 54 to rotate under the action of the belt 55, and the raw materials added to the feed hopper 4 are moved, which can prevent the feed hopper 4 from being blocked when feeding. The rotation of the motor 1 32 shaft drives the rotation of the conveying auger 33, and the raw materials falling into the inclined tube 31 are transported upward through the discharge pipe 34 and discharged into the box body 1. To cool the raw materials, the air pump 133 is controlled to operate. The rotation of the turntable 67 drives the rotation of the short rod 68, and then the movable frame 65 moves up and down reciprocatingly, and the connecting plate 64, the vertical rod 61, the U-shaped plate 62 and the roller 63 move up and down reciprocatingly, so that the multiple grate cooling plates 2 rotate and shake reciprocatingly, and the raw materials are gradually transported. At the same time, the air pump 133 discharges the gas from the gas outlet 134 through the connecting pipe 132 and the L-shaped pipe 131, which can gradually transport and cool the raw materials, and drive the multiple grate cooling plates 2 to rotate and shake reciprocatingly through a motor 32, which is more practical.
