A motor 5 is fixedly connected to the first limit plate 4. The output end of the motor 5 is fixedly connected with a driving rotating shaft 6. The driving rotating shaft 6 passes through and is rotatably connected to the first limit plate 4. One end of the driving rotating shaft 6 away from the motor 5 is fixedly connected with a driving bevel gear 7. A driven bevel gear 8 is meshed with the driving bevel gear 7. A driving connecting rod 9 is fixedly connected through the driven bevel gear 8. Both ends of the driving connecting rod 9 pass through and are rotatably connected to a second limit plate 10. The second limit plate 10 is fixedly connected to the bottom plate 2. Rear sprockets 11 are fixedly connected to both ends of the second limit plate 10. A first belt pulley 12 is fixedly connected through one end of the driven bevel gear 8. A transmission belt 13 is meshed with the first belt pulley 12. A second belt pulley 14 is meshed with the end of the transmission belt 13 away from the first belt pulley 12. A driving connecting rod 15 is fixedly connected through the second belt pulley 14. Both ends of the driving connecting rod 15 pass through and are rotatably connected to a third limit plate 16. The third limit plate 16 is fixedly connected to the bottom plate 2. Front sprockets 17 are fixedly connected to both ends of the third limit plate 16. The rear sprockets 11 and the front sprockets 17 are rollingly connected to the first limit slide bars 3. The rotation of the driving bevel gear 7 drives the rotation of the driven bevel gear 8. The rotation of the driven bevel gear 8 drives the rotation of the driving connecting rod 9. The rotation of the driving connecting rod 9 drives the rotation of the rear sprockets 11 at both ends. At the same time, the rotation of the driving connecting rod 9 drives the rotation of the driving connecting rod 15 through a transmission mechanism. The rotation of the driving connecting rod 15 drives the rotation of the front sprockets 17 at both ends. Thus, the discharging trolley can automatically move back and forth on the first limit slide bars 3 in the tunnel kiln for discharging, thereby greatly saving the physical strength of manual material handling and improving the discharging efficiency.

[0028] On both sides of the bottom plate 2, vertical plates 22 are fixedly connected. On the bottom plate 2, a mounting plate 18 is fixedly connected. On the mounting plate 18, a first electric push rod 19 is fixedly connected. The output end of the first electric push rod 19 is fixedly connected with a first telescopic rod 20. The end of the first telescopic rod 20 far from the first electric push rod 19 is fixedly connected with a fixing plate 21. The fixing plate 21 is slidably connected to the bottom plate 2 and the fixing plate 21 is slidably connected to the vertical plate 22. At the end of the bottom plate 2 far from the mounting plate 18, a cross bar 23 is fixedly connected. On the cross bar 23, a second electric push rod 24 is fixedly connected. The output end of the second electric push rod 24 is fixedly connected with a second telescopic rod 25. Both ends of the second telescopic rod 25 are fixedly connected with a connecting rod 26. The end of the connecting rod 26 far from the second telescopic rod 25 is fixedly connected with a second sliding rod 28. On the cross bar 23, a hollow rod 27 is fixedly connected. The second sliding rod 28 is slidably connected through the hollow rod 27. The end of the second sliding rod 28 far from the hollow rod 27 is fixedly connected with a top rod 29. The top rod 29 is slidably connected to the vertical plate 22. By starting the second electric push rod 24, the output end of the second electric push rod 24 drives the second telescopic rod 25 to move up and down. The up and down movement of the second telescopic rod 25 drives the second sliding rod 28 and the top rod 29 to move up and down. Thus, the height of the baffle can be adjusted, which is convenient for subsequent workers to unload goods from the discharging device. At both ends of the bottom plate 2, sliders 31 are fixedly connected. On both sides of the tunnel kiln body 1, chutes 30 are provided. The sliders 31 are slidably connected to the chutes 30. On the bottom plate 2, a support rod 32 is fixedly connected. The end of the support rod 32 far from the bottom plate 2 is fixedly connected with a handle 33. There are two groups of the second electric push rods 24, and the two groups of the second electric push rods 24 are evenly distributed on the cross bar 23. There are two groups of the first electric push rods 19, and the two groups of the first electric push rods 19 are evenly distributed on the mounting plate 18.

[0029] Working principle: First, a certain amount of goods are loaded on the bottom plate 2, and then the motor 5 is started. The output end of the motor 5 drives the driving rotating shaft 6 to rotate. The rotation of the driving rotating shaft 6 drives the driving bevel gear 7 to rotate. The rotation of the driving bevel gear 7 drives the driven bevel gear 8 to rotate. The rotation of the driven bevel gear 8 drives the driving connecting rod 9 to rotate. The rotation of the driving connecting rod 9 drives the rear sheave wheels 11 at both ends to roll on the first limit slide rod 3. At the same time, the rotation of the driving connecting rod 9 drives the first pulley 12 to rotate. The rotation of the first pulley 12 drives the transmission belt 13 to rotate. The rotation of the transmission belt 13 drives the second pulley 14 to rotate. The rotation of the second pulley 14 drives the driving connecting rod 15 to rotate. The rotation of the driving connecting rod 15 drives the front sheave wheels 17 at both ends to roll on the first limit slide rod 3. Thus, the discharging trolley can automatically move back and forth in the tunnel kiln body 1 to transport goods. At the same time, the movement of the bottom plate 2 drives the slider 31 to slide in the chute 30 on the tunnel kiln body 1, which greatly saves the physical strength of manual material handling and improves the discharging efficiency. Then, the first electric push rod 19 is started. The output end of the first electric push rod 19 drives the first telescopic rod 20 to push the fixing plate 21 forward to clamp the goods in cooperation with the vertical plate 22, the hollow rod 27, the second slide rod 28, and the ejector rod 29 to prevent them from falling during transportation. Finally, by starting the second electric push rod 24, the output end of the second electric push rod 24 drives the second telescopic rod 25 to lift. The lifting of the second telescopic rod 25 drives the second slide rod 28 to slide up and down in the hollow rod 27. The up and down sliding of the second slide rod 28 drives the ejector rod 29 to slide up and down on the vertical plate 22. In this way, the height of the baffle can be adjusted to facilitate subsequent workers to unload the goods from the discharging device.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
