The jacking mechanism can adopt an oil cylinder or an air cylinder, the jacking mechanism cooperates with the connecting rod mechanism to realize the automatic adjustment of the inclination angle of the chain conveying belt, the structure is simple, the design is ingenious, and the inclination angle adjustment is convenient and fast.

[0006] In the above-mentioned scheme: each chain conveying belt is connected as a whole through a synchronous rod, which is helpful to improve the consistency of the inclination angle adjustment of the chain conveying belt.

This design avoids the reinforcing bars from piling up during transport and has a certain sorting effect. In summary, this utility model has a simple structural design, can realize transport in two directions, and effectively avoids the piling up of reinforcing bars during transport.

[0017] like Figure 1 As shown in Figure 4, a tunnel steel bar feeding and sorting device has a main body of frame 1. A longitudinally extending roller conveyor belt 2 is provided on the frame 1. The roller conveyor belt 2 is used for feeding whole bundles of steel bars. A limiting plate 3 is provided at the end of the roller conveyor belt 2.

[0018] Multiple sets of chain conveyor belts 4 are arranged side-by-side below the roller conveyor belt 2. The chain conveyor belts 4 extend laterally and are fixed to the frame 1 by a linkage mechanism 5, which is equipped with a power mechanism. The power mechanism can drive the linkage mechanism 5 to move, thereby driving the chain conveyor belts 4 to adjust their tilt angle. After adjustment, the chain conveyor belts 4 can lift the steel bars on the roller conveyor belt 2 and transport them in an upward inclined direction.

The right link 52 is an inclined arc-shaped link, with its upper left end hinged to the frame of the chain conveyor belt 4 and its lower right end hinged to the frame 1.

[0020] When the lifting mechanism moves upward, it drives the linkage mechanism 5 to move, thereby causing the frame of the chain conveyor belt 4 to tilt upward, thus realizing the tilt angle adjustment of the chain conveyor belt 4. The lifting mechanism can be a hydraulic cylinder or a pneumatic cylinder. The lifting mechanism and the linkage mechanism 5 work together to realize the automatic adjustment of the tilt angle of the chain conveyor belt 4. The structure is simple, the design is ingenious, and the tilt angle adjustment is convenient and fast.

[0021] Ideally, each chain conveyor belt 4 should be connected as a whole by a synchronizing rod 6, which helps improve the consistency of the tilt angle adjustment of the chain conveyor belt 4. There are two synchronizing rods 6, which are respectively located at the left and right ends of the chain conveyor belt 4 to ensure the connection effect.

[0022] Ideally, the feed end of the roller conveyor belt 2 is equipped with auxiliary idlers 7, which provide support at the feed end and facilitate feeding.

[0023] Ideally, the bottom of the frame 1 should be equipped with a walking device (not shown in the figure). The walking device can be a caster wheel with locking function. The walking device facilitates the movement of the tunnel steel bar loading and sorting equipment.
