[0007] The technical scheme of the utility model is specifically as follows:

[0008] A shower type receiving chute comprises a chute body and a frame body, a wear-resistant lining plate is fixed in the chute body, a plurality of water channels are arranged on the wear-resistant lining plate, a plurality of water pipe branch lines are arranged in the chute body, the water channels are communicated with the water pipe branch lines, the plurality of water pipe branch lines are gathered into a water pipe bus, the outlet of the water pipe bus extends to the outside of the chute body, a water spraying pipe is arranged above the chute body, and the water spraying direction of the water spraying pipe is consistent with the axial direction of the chute body.

[0009] The wear-resistant lining plate comprises a plurality of lining plate units, and the gap between two adjacent lining plate units is a water channel.

[0010] Compared with the prior art, the technical effect of the utility model is that in the return process of the push rod, the water spraying pipe sprays water, and the water sprayed by the water spraying pipe carries the iron oxide skin and flows into the outlet of the water pipe bus. In this step, not only the iron oxide skin is removed, but also the wear-resistant lining plate and the push rod are cooled, and the service life of the two can be prolonged.
