[0030] Further, a conveying roller 3 is rotatably connected inside the fixed frame 1. The support plate 6 is located between the conveying rollers 3.

[0031] By adopting the above technical solution, since the support plate 6 is located between the conveying rollers 3, the support plate 6 can lift the materials on the conveying roller 3.

[0032] Further, a transmission mechanism 7 is provided on the support plate 6. The top end of the fixed plate 5 is fixedly connected to a second gearbox 703. The bottom end of the second gearbox 703 is fixedly connected to a second motor 702. The second gearbox 703 is connected to a third connecting shaft 704 through a coupling 202. A first gear 705 is fixedly connected to the outer circumferential surface of the third connecting shaft 704. A first rotating shaft 706 is fixedly connected inside the support plate 6.

[0033] Further, meshing rotating chains are provided on the first gear 705, the second gear 707 and the third gear 709, and the rotating chains are fixedly connected to the conveyor belt 701.

[0034] By adopting the above technical solution, the longitudinal conveying of materials can be carried out through the transmission mechanism 7 on the support plate 6.

[0035] Further, an adjusting and tensioning mechanism 8 is provided on the support plate 6. One end of the support plate 6 is fixedly connected to a connecting block 801.

[0037] By adopting the above technical solution, the conveyor belt 701 can be properly tensioned through the adjusting and tensioning mechanism 8 on the support plate 6, which can reduce the damage and wear of the conveyor belt 701 and ensure the stable conveying of materials.

[0038] Further, a support frame 4 is fixedly connected inside the fixing frame 1. A linear bearing 9 is fixedly connected inside the support frame 4. The bottom end of the fixed plate 5 is fixedly connected to a guide shaft 10. The guide shaft 10 is slidably connected to the linear bearing 9.

[0039] By adopting the above technical solution, through the guide shaft 10 and the linear bearing 9, the direction stability of the fixed plate 5 during linear motion is ensured.

[0040] Working principle: When the material moves to the support plate 6 through the conveying roller 3 on the fixed frame 1, the first motor 205 is started. The first motor 205 drives the first gearbox 206 to rotate. The first gearbox 206 drives the first lifters 201 and the fourth lifter 209 on both sides to lift the fixed plate 5 through the coupling 202. At the same time, the first lifter 201 drives the second lifter 204 to lift the fixed plate 5 through the coupling 202 and the first connecting shaft 203. The fourth lifter 209 drives the third lifter 208 to lift the fixed plate 5 through the coupling 202 and the first connecting shaft 203, so that the first lifter 201, the second lifter 204, the third lifter 208 and the fourth lifter 209 lift the fixed plate 5 synchronously. The fixed plate 5 will drive the support plate 6 to move upward. The support plate 6 will drive the conveyor belt 701 to extend upward from between the conveying rollers 3 and lift the material. When the material is lifted to the specified position, the second motor 702 is started. The second motor 702 drives the second gearbox 703 to rotate. The second gearbox 703 drives the third connecting shaft 704 through the coupling 202. The third connecting shaft 704 drives the first gear 705 to rotate. The first gear 705 drives the conveyor belt 701 to rotate through the rotating chain. The rotating chain drives the second gear 707 and the third gear 709 to rotate. The second gear 707 rotates on the first rotating shaft 706 through the bearing 710. The third gear 709 rotates on the second rotating shaft 708 through the bearing 710. In this way, the conveyor belt 701 conveys the material longitudinally. However, before the synchronous jacking mechanism 2 lifts the fixed plate 5, the position of the second rotating shaft 708 in the sliding groove 802 on the support plate 6 can be adjusted by adjusting the bolts 803 and nuts 804 on the connecting block 801. The second rotating shaft 708 adjusts the tension of the conveyor belt 701 through the bearing 710 and the third gear 709 to ensure the stable conveying of the material by the conveyor belt 701.
