In the process of material conveying, its smooth running is related to the speed and efficiency of the whole transportation process. However, for the huge cargo throughput of port transportation, due to the uneven distribution of materials and the inaccuracy of the material falling point, the materials at the turning point of the existing belt conveyor are thrown out due to inertia under the driving of the belt speed, and a straight baffle is usually used to block the materials, which has good effect, but the stress at the turning point of the belt changes greatly, and the belt is prone to deviation. The common deviation correcting device of the belt includes a rotary roller, a hydraulic sensor matched with a driving oil cylinder to make the piston rod extend and retract to drive the roller frame to move, and a pneumatic automatic deviation correcting device. However, the above structure cannot be installed on large port machinery such as ship loaders, and it is also difficult to correct the deviation of the belt for transporting materials of 10 tons or more. Therefore, it is necessary to design a simple and easy-to-install structure to solve the above problems. SUMMARY

[0033] The inner side of the baffle 10 is further provided with a flow distribution plate 11 along the belt movement direction, the flow distribution plate 11 being arranged obliquely from both sides of the belt to the center of the belt, the flow distribution plate 11 being symmetrically arranged along the belt movement direction and being provided with at least two, and an opening 12 being left between the two flow distribution plates. The opening 12 is further provided with a V-shaped plate 13 along the belt movement direction, the tip of the V-shaped plate 13 being opposite to the opening, and the width of the V-shaped plate being not greater than 1 / 3 of the width of the belt. The baffle 10 is hingedly provided with a movable plate 30, the flow distribution plate 11 and the V-shaped plate 13 being arranged on the movable plate 30, the movable plate 30 extending a support plate 31 to the back side of the baffle 10, the support plate 31 being connected with a first spring 32, the other end of the first spring 32 being connected with the baffle 10. The baffle 10 is provided with a rotating seat 14 adapted to the first spring 32, the rotating seat 14 being rotatably connected with a support column 15, the support column 15 being connected with the first spring 32. The rotating seat 14 is internally provided with a limiting piece 16, the limiting piece enabling the support column 15 to rotate within a certain angle.

[0034] The inner side of the baffle 10 is provided with a rubber plate 40, the rubber plate 40 being provided with screw holes 41, bolts 42 being connected with nuts 43 through the screw holes 41 and the baffle 10, rubber being encapsulated between the head of the bolt and the rubber plate 40, so that the bolt is embedded into the rubber plate, and the bolts 42 are uniformly arranged on the baffle 10. The outer side of the baffle 10 is provided with a reinforcing piece 17.

[0035] The side plate 20 comprises an inner side plate 22 and an outer side plate 23 in clearance fit, the inner side plate 22 and the outer side plate 23 being respectively provided with guide rods 24, the guide rods 24 being externally provided with second springs 25, the guide rods being radially provided with spring seats 26, and the second springs 25 being connected to the spring seats 26.

[0036] Working principle:

[0037] When the material enters the turning area with the belt, it first encounters the flow divider 11. The flow divider 11 is inclined from both sides of the belt to the center, so that the material will be guided when it contacts the flow divider, and begin to gather to the center of the belt. As the material continues to advance, they will pass through the opening 12 between the flow dividers 11. The design of the opening 12 allows most of the material to pass smoothly, without being blocked by the flow divider. At the same time, the V-shaped plate 13 is located below the opening 12, with its tip facing the opening. The function of the V-shaped plate is to evenly distribute the material on the surface of the belt, reducing the problem of deviation caused by uneven stress on the belt.

[0038] When the material flow on the belt is too large, it will impact the flow divider and V-shaped plate and drive the movable plate 30 to rotate. The movable plate will produce a certain rotation due to the weight and inertia of the material. This rotation is absorbed by the first spring 32, thereby acting as a buffer and allowing the movable plate 30 to reset by the first spring 32.

[0039] The side plate 20 includes a clearance fit inner side plate 22 and an outer side plate 23, which form a cavity 27 between them. The guide rod 24 is provided with a second spring 25 outside, connected to the spring seat 26. This design provides additional support and buffering effect, and also allows the side plate to move relatively within a certain range to adapt to different working conditions.

[0040] The rotating seat 14 is provided with a limiting piece 16 inside, which limits the rotation of the support column 15 within a certain angle. This ensures the stability and reliability of the baffle, preventing instability or damage caused by excessive rotation.

[0041] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the ordinary technical personnel in the art, without departing from the technical principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
