Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of material distributor, specifically relates to a prevent blocking three -way material distributor. BACKGROUND

[0002] In the chemical industry, metallurgy, grain, building materials, port, power, coal, mine and other bulk material conveying system often need to use belt conveyor to shunt the material. When the belt conveyor is conveying material, the funnel and the chute are usually connected by a tee structure to achieve the purpose of shunting the material to two conveyors. Since most of the conveyed materials are blocky or granular, the tee structure often has a blockage problem.

[0003] In order to solve the above problems, an oil cylinder is usually installed outside the tee structure. The oil cylinder pushes the rotating shaft of the flap assembly inside the tee through a rocker arm to control the flow direction of the material. However, the oil cylinder thrust of this structure is transmitted through the rocker arm. When the tee is blocked, the flap assembly is difficult to respond, which affects the normal operation of the belt conveyor, increases the time cost, and reduces the economic benefit. In the prior art, there is a public number 202499540U, named: flap tee material distributor. In this patent document, the piston rod of the electric push rod drives the adjustment of the flap angle through the connecting plate, thereby changing the size of the discharge port and reducing the probability of being stuck. Since the electric push rod is first hinged to the connecting plate, and then drives the change of the flap angle through the connecting plate, according to mechanical knowledge and lever axiom, the device will cause the electric push rod to lose a lot of energy when in use. Therefore, when the volume of the falling material is large, the angle of the flap is difficult to reach the predetermined position, so the material distributor can only be used for small equipment, and the rigidity and stability are poor.
