Description

Technical Field

[0001] The utility model relates to the technical field of conveyor unloading, in particular to a four-way trough buffer device for a belt conveyor unloading vehicle. Background Art

[0002] As a special unloading device for belt conveyors, unloading vehicles are widely used in industries such as steel, coal mines, cement plants, and ports. Unloading is mainly achieved through three-way chutes and four-way chutes. When a four-way chute is used, the middle unloading position is prone to material spillage because the conveyor belt below is horizontal. On the other hand, the material has a greater impact on the conveyor belt, which is not conducive to improving the service life of the conveyor belt. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a belt conveyor unloading vehicle four-way trough buffer device which has a reasonable structural design, can prevent material from being scattered and effectively reduce the impact of materials on the conveyor belt.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a four-way trough buffer device for a belt conveyor unloading vehicle, comprising a frame and a four-way chute installed on the frame, the four-way chute comprising a feed hopper, a side discharge chute and an intermediate discharge chute, a trough-shaped buffer roller group is installed on the frame below the discharge port of the intermediate discharge chute, a rubber guard plate is installed around the discharge port of the intermediate discharge chute, the rubber guard plate extends downward to force the conveyor belt to contact the trough-shaped buffer roller group to make the conveyor belt into a trough structure.

[0005] As a preferred technical solution, 2 to 4 groups of the grooved buffer roller groups are provided.

[0006] As a preferred technical solution, the side discharge chute includes an inclined section and a vertical section, and a buffer plate is installed on the vertical section.

[0007] As a preferred technical solution, diverter flaps are respectively installed on the discharge channels of the side discharge chute and the middle discharge chute, and the diverter flaps are connected to electro-hydraulic push rods.

[0008] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: a groove-shaped buffer roller group is installed on the frame below the discharge port of the intermediate discharge chute, and a rubber guard plate is installed around the discharge port of the intermediate discharge chute. The rubber guard plate extends downward to force the conveyor belt to contact with the groove-shaped buffer roller group to make the conveyor belt into a groove-shaped structure, which can ensure that the material will not be scattered when it falls on the conveyor belt, and the problem of material scattering can be effectively avoided. At the same time, due to the rubber ring structure on the surface of the buffer roller, the impact of the material on the conveyor belt is greatly reduced, which is beneficial to increasing the service life of the conveyor belt.

[0013] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0014] like Figures 1 to 3 As shown, the four-way trough buffer device of the belt conveyor unloading vehicle includes a frame 1 and a four-way chute 2 installed on the frame 1, the four-way chute 2 includes a feed hopper 21, two side unloading chutes 22 and an intermediate unloading chute 23, and a trough-type buffer roller group 3 is installed on the frame 1 below the unloading port of the intermediate unloading chute 23. The trough-type buffer roller group 3 is preferably provided with 2 to 4 groups, and 3 groups are taken as an example in this embodiment; each trough-type buffer roller group 3 is composed of 3 buffer rollers. A rubber guard plate 4 is installed around the unloading port of the intermediate unloading chute 23, and the rubber guard plate 4 extends downward to force the conveyor belt 5 to contact with the trough-type buffer roller group 3 so that the conveyor belt 5 here forms a trough structure, so that the material will not be scattered when it falls from the intermediate unloading chute 23 to the conveyor belt, effectively avoiding the problem of material scattering. At the same time, due to the rubber ring structure on the surface of the buffer roller, the impact of the material on the conveyor belt is greatly reduced, which is conducive to improving the service life of the conveyor belt.

[0015] The grooved buffer roller group 3 is installed on the frame 1 and can be adjusted in height up and down, so as to adjust the groove angle formed by the conveyor belt 5.

[0016] The side discharge chute 22 includes an inclined section 221 and a vertical section 222 . A buffer plate 223 is installed on the vertical section 222 to mitigate the impact of falling materials on the inner wall of the chute.

[0017] The side discharge chute 22 and the middle discharge chute 23 are respectively provided with diverter flaps 24, and the diverter flaps 24 are connected with electro-hydraulic push rods 25. The opening angle of the diverter flaps 24 is controlled by the electro-hydraulic push rods 25, so as to control the diversion and adjust the discharge amount of each discharge chute.

[0018] The structural design of this device is simple and reasonable. Through optimized and innovative design, compared with traditional unloading vehicles, it not only solves the problem of belt material spillage, but also reduces the impact of materials on the conveyor belt, thereby increasing the service life of the conveyor belt and greatly improving the market competitiveness and pioneering power of the company's products.

[0019] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
