[0015] Figure 1 It is a structural schematic diagram of the utility model.

[0016] Figure 2 It is a structural schematic diagram of the lower feeding device of the utility model.

[0017] Figure 3 The structure diagram of the lower unloading device of the utility model is shown in FIG. Figure 1 .

[0018] Figure 4 The structure diagram of the lower unloading device of the utility model is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0019] The utility model is further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, the conveyor includes an upper conveying section 2-1 and a lower conveying section 2-2. A lower loading device 6 is provided at one end of the lower conveying section 2-2, and a lower unloading device 9 is provided at the other end of the lower conveying section 2-2. A lower tensioning shaft 5 is provided on the inner side of the conveyor belt near the lower loading device 6, and an auxiliary driving shaft 7 and a unloading redirecting roller 8 are provided on one side of the conveyor belt near the front end of the lower unloading device 9. A feed port 6-1 is provided on the left and right sides of the upper end of the lower loading device 6, and a discharge port 1 6-2 is provided on the lower end. A discharge port 9-1 is provided on the upper end of the lower unloading device 9, and a discharge port 2 9-2 is provided on the left and right sides of the lower end of the lower unloading device 9.

[0021] A space for the conveyor belt to pass through is provided between the feed ports 6-1 on the left and right sides to avoid the conveyor belt. The lower end of the discharge port 1 6-2 is aligned with the conveyor belt. A space for the conveyor belt to pass through is provided between the discharge ports 2 9-2 on the left and right sides to avoid the conveyor belt.

[0022] The unloading redirection roller 8 is located at the lower left of the auxiliary drive shaft 7, and the conveyor belt passes through the auxiliary drive shaft 7 and the unloading redirection roller 8 in sequence, forming a Z-shaped arrangement. Figure 3 to Figure 4 As shown, the lower unloading device 9 is located at the Z-shaped bend. When the material passes through the conveyor belt at the upper end of the auxiliary drive shaft 7, it enters the unloading port 9-1 at the upper end of the lower unloading device 9 and goes out from the second discharge port 9-2 to complete the unloading.

[0023] An upper feeding device 1 is provided at one end of the upper conveying section 2-1, and an upper unloading device 4 is provided at the other end of the upper conveying section 2-1. When used specifically, one or more upper feeding devices 1 can be provided to facilitate flow control of feeding at different positions.

[0024] A driving shaft 3 and an upper tensioning roller 11 are respectively provided at both ends of the conveyor, and a redirecting roller 10 is provided below the upper tensioning roller 11 .

[0025] Auxiliary tensioning rollers 5 - 1 are respectively provided at the front and rear of the lower tensioning shaft 5 .

[0026] A cleaning device 13 is provided at the front side of the lower loading device 6 and the front side of the lower unloading device 9 .

[0027] Belt turning devices 12 are respectively provided at the head and tail ends of the lower conveying section 2-2.

[0028] The conveyor is a tubular conveyor or a trough belt conveyor.

[0029] When the utility model is used, both the upper conveying section and the lower conveying section can convey materials. When the upper conveying section 2-1 conveys materials, material A enters from the upper feeding device 1, is conveyed by the upper conveying section, and is discharged from the upper discharge device 4. The conveyor belt entering the lower conveying section 2-2 is turned over by the turning device 12, and material B enters from the feeding port 6-1 of the lower feeding device 6, and falls from the discharge port 1 6-2 to the lower conveying section 2-2 for conveying, and when it reaches the auxiliary drive shaft 7. Due to the different height positions of the auxiliary drive shaft 7 and the discharge redirection roller 8, the material enters the discharge port 9-1 of the lower discharge device 9 and is discharged from the discharge port 2 9-2. The conveyor belt is then turned over by the turning device 12.

[0030] The cleaning device 13 cleans the conveyor belt to prevent different materials remaining on the conveyor belt from mixing together.
