Description

Technical Field

[0002] Reciprocating feeder is suitable for mines and coal preparation plants to load coal evenly from coal bunkers to conveyors or other screening and storage devices. The structure and working principle of reciprocating feeder are as follows: a feeding bottom plate is set at the bottom of the feeding bunker, and the feeding bottom plate is movable. The power device drives the feeding bottom plate to reciprocate. When the feeding bottom plate moves toward the feeding port, the material moves with the bottom plate to complete the feeding process.

[0003] The reciprocating feeder in the prior art generally has the following technical problems during use:

[0004] 1. The material is fed with the movement of the bottom plate, and the feeding position is relatively fixed. However, the feeder usually needs to cooperate with different equipment. The feeding position has poor flexibility and is not easy to adjust, which sometimes affects the feeding process;

[0005] 2. The gate is used to adjust the opening size of the feed port. When the material is piled up too much, it is easy to cause excessive gate pressure, resulting in bending and deformation, which will affect subsequent use.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
