A four-way feeder that does not jam

Abstract

The invention relates to a four-way material distributer free of material blocking. A set of electric liquid pushing rods, a swing arm and an overturning plate are adopted for the four-way material distributer. The electric liquid pushing rods are arranged on a shell. The overturning plate is rotationally fixed in a cavity through a rotating shaft. One end of the swing arm is fixed to the rotating shaft, and the other end of the swing arm is hinged to the electric liquid pushing rods. The overturning plate comprises two parallel baffles and a plurality of partition plates vertically fixed between the baffles and parallel to each other. The two baffles are right opposite to the inner walls on the two sides of the cavity. A material collecting opening is formed in the bottom end of a vertical material inlet and always located between the two baffles. The overturning plate is made to rotate, materials are limited by the baffles and guided by the partition plates to enter a material discharge connector to which the partition plates point. The four-way material distributer effectively prevents the material clamping phenomenon, switching of three flow directions can be achieved through the set of electric liquid pushing rods, the swing arm and the overturning plate, cost is low, and operation is reliable.

Description

technical field [0001] The invention relates to a bulk material conveying device, in particular to a four-way distributor without material jamming. Background technique [0002] The four-way feeder is a common device used to switch the flow direction of materials during material transfer. It is generally used in the working conditions of one upstream and one downstream to three channels and only one channel can be connected during bulk material transfer. Such as figure 1 As shown, the existing four-way distributor includes a housing, two sets of electro-hydraulic push rods, a swing arm and a flap. The electro-hydraulic push rod drives the flap to rotate through the swing arm, and the two flaps cooperate with each other to realize three flow directions. However, the existing four-way feeder has the following problems: 1) The flap is horizontal to the inside of the housing and there is a gap with the inner wall of the housing. In actual use, material leakage and jamming are p...

Problems solved by technology

like figure 1 As shown, the existing four-way distributor includes a housing, two sets of electro-hydraulic push rods, a swing arm and a flap. The electro-hydraulic push rod drives the flap to rotate through the swing arm, and the two flaps cooperate with each other to realize three flow directions. However, the existing four-way feeder has the following problems: 1) The flap is horizontal to the inside of the housing and there is a gap with the inner wall of the housing. In actual use, material leakage and jamming are prone to occur. Problems such as material loss and mixing will affect normal production, and material jams will lead to overload of the electro-hydraulic push rod, or failure to push the flap, and even cause serious equipment failures such as broken shafts of the flap; 2) two sets of electro-hydraulic push rods, pendulum The arm and the flap need to be closely matched to complete the switching of the flow direction. When a problem or failure occurs in one group, the other group alone cannot complete the switching of the flow direction. Not only is the operation and maintenance complicated, the cost is high, and it is not reliable.
