Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a discharging device for a belt conveyor. Background Art

[0002] Belt conveyors have the advantages of wide adaptability and reliable operation, so they have been preferentially adopted as conveying equipment for normal-temperature raw fuels in recent years. There are many layout forms of belt conveyors, and the common ones are horizontal, inclined or horizontal-inclined layout forms. The discharging point is generally arranged at the head. When the discharging is arranged in the middle or other positions, a plough-type discharging device is generally added to the belt conveyor. However, when conveying materials with a relatively heavy bulk density, especially when the belt conveyor is arranged in an inclined manner, the plough-type discharging device often fails to reach the designed transportation volume during discharging, and it is easy to cause scratches on the conveying rubber surface, increasing the workload of maintenance personnel.

[0018] The following further details the specific embodiments of the present utility model by describing the embodiments with reference to the drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0019] It should be noted that in the following embodiments, the "first", "second" and "third" do not represent an absolute distinction relationship in structure and / or function, nor represent the execution order, but are only for the convenience of description.

[0020] As Figures 1 to 3As shown in the figure, the utility model provides a discharge device for a belt conveyor, which includes a head frame 4, a first redirecting roller 1, a second redirecting roller 2, and a four-way distributor 5 for conveying materials to different belt conveyors. The four-way distributor 5 is provided with a feed inlet, a first discharge outlet, a second discharge outlet, and a third discharge outlet. The feed inlet is located above the first discharge outlet, the second discharge outlet, and the third discharge outlet. The second discharge outlet and the third discharge outlet are respectively located on both sides of the first discharge outlet. The first redirecting roller 1 is directly opposite to the feed inlet of the four-way distributor 5, and the first redirecting roller 1 is used to guide the materials from the first belt conveyor to the feed inlet of the four-way distributor 5.

[0021] Specifically, as Figure 3 shown, the four-way distributor 5 includes a housing. Two flap plates are arranged inside the housing. The two flap plates are rotatably arranged. The two flap plates are at the same height. The rotation center lines of the two flap plates are parallel to each other. The two flap plates cooperate to control the opening and closing of the first discharge outlet, the second discharge outlet, and the third discharge outlet. The feed inlet is located at the top of the housing. The first discharge outlet is located at the bottom of the housing. The first discharge outlet is directly below the feed inlet. The first discharge outlet is located above the second belt conveyor. After the first discharge outlet is opened, the materials entering the housing fall onto the conveyor belt 6 of the second belt conveyor below through the first discharge outlet. After the second discharge outlet and the third discharge outlet are opened, the materials entering the housing fall onto the conveyor belts of the remaining belt conveyors through the second discharge outlet and the third discharge outlet respectively. The second discharge outlet and the third discharge outlet discharge materials towards two outer sides of the conveyor belt 6 of the second belt conveyor respectively.

[0022] The three discharge outlets of the four-way distributor 5 respectively correspond to different belt conveyors, so as to convey different materials to different belt conveyors. When two or more different heavy-quality materials are respectively conveyed on the first belt conveyor and are restricted by the existing site height, the postures of the two flap plates of the four-way distributor 5 can be adjusted to control the opening of different discharge outlets of the four-way distributor 5, reduce the damage to the rubber surface of the conveyor belt, freely change the material conveying direction, and at the same time reduce the cost of adding belt conveyors for conveying different materials.

[0023] As Figure 3 shown, the two flap plates of the four-way distributor 5 are respectively connected to two actuators. The actuators are used to control the rotation of the flap plates. The actuators are arranged on the housing. The two actuators simultaneously control the rotation of the two flap plates or respectively control the rotation of the two flap plates. By adjusting the posture of the flap plates, the material conveying direction is changed.

[0024] As Figure 1 and Figure 2As shown, the height of the first redirecting roller 1 is greater than that of the second redirecting roller 2. The first redirecting roller 1 and the second redirecting roller 2 are installed on the headstock 4, the headstock 4 is fixedly connected to the head wheel guard 3, and the four-way distributor 5 is connected to the head wheel guard 3. The second redirecting roller 2 is used to guide the materials from the second belt conveyor to other positions, and the parallel belts are pulled apart by a height difference through the two redirecting rollers.

[0025] In this embodiment, the first redirecting roller 1 and the second redirecting roller 2 are fixedly installed on the headstock 4 by bolts, the four-way distributor 5 is fixedly installed on the head wheel guard 3 by screws, and the headstock 4 and the head wheel guard 3 are composed of welded sections and ordinary steel plates. The headstock 4 is fixed on both sides of the intermediate frame of the second belt conveyor, and the conveyor belt 6 of the second belt conveyor passes through the headstock 4. In this way, the four-way distributor 5 enables the materials to be freely unloaded onto other conveyor belts other than this machine through 2 flap plates. The four-way distributor 5 does not contact the conveyor belt 6 to prevent damage to the conveyor belt.

[0026] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
