Description

Technical Field

[0001] The present invention relates to the technical field of bulk material conveying, and in particular to a six-way bulk material distributing device and a control method thereof. Background Art

[0002] Belt conveyors are commonly used equipment for conveying bulk materials. There are three ways to distribute bulk materials to five bins through a belt conveyor as follows:

[0003] 1) A buffer bin is arranged below the head of the belt conveyor. The buffer bin is provided with five discharge openings and corresponding gates. The five bins are evenly arranged circumferentially. However, this method has problems such as a large occupied space of the buffer bin, many required equipment, and easy blockage of the buffer bin. Moreover, each bin can only be filled separately, which easily causes the bin to tilt due to uneven filling.

[0004] 2) Four bins are arranged in a ring below the head of the belt conveyor, and a central bin is arranged at the center. A reversible rotary distributor is used for filling. When the reversible rotary distributor rotates forward, it fills the four peripheral bins, and when it rotates backward, it fills the central bin. When this method is adopted, the filling uniformity is better, but the equipment is complex, the investment is large, and there are many fault points in the continuous running mechanisms such as the rotary mechanism and the reversible running mechanism of the reversible rotary distributor, resulting in unstable system operation.

[0005] 3) A four-way distributor (such as a "flap-type four-way switching distributor" disclosed in a Chinese utility model patent with the authorized announcement number CN 202499539 U) and two reversible belt conveyors are arranged below the head of the belt conveyor. One discharge opening at the center of the four-way distributor fills the central bin, and the other two discharge openings fill the other four bins respectively through two vertically arranged reversible belt conveyors. The disadvantage of this method is that more equipment is invested and the occupied space is large. Summary of the Invention

[0006] The present invention provides a six-way bulk material distributing device and a control method thereof. The layout of the six-way bulk material distributing device and the five bins is reasonable, the structure is compact, and the occupied space is small; an electro-hydraulic push rod is used as the driving device of the flap valve, with simple operation and fast response speed; remote control can be realized through the control system; simultaneous filling of symmetric bins can be realized, effectively avoiding the tilting of the bins due to uneven filling.
