To achieve the above object, the present invention proposes a kind of hopper dredging system；Including hopper body, installed in hopper body
Power dredger in bulkhead, installed in the pneumatic hammer of hopper body lower part；The hopper body includes elevating hopper section and cone
Shape hopper section, elevating hopper section are connected with broach hopper section；The elevating hopper section includes circular hopper or square hopper；It is described
Power dredger is arranged at the inwall of broach hopper section；The pneumatic hammer is arranged on the middle and lower part of broach hopper section bulkhead.
The power dredger includes two dredgers being symmetricly set in broach hopper section bulkhead.
The power dredger includes hydraulic cylinder, pull bar and scraper plate；The pull bar is connected by connector with hydraulic cylinder
And driven and moved back and forth by hydraulic cylinder；Scraper plate matching is arranged on pull bar.
The hydraulic cylinder is located at the medium position of broach hopper section bulkhead, pull bar extend from the top down along bulkhead it is certain away from
From；Pull bar is formed by steel plate butt welding, and its cross sectional shape is polygon.
Scraper plate mounting hole is provided with the pull bar, scraper plate is fixed on pull bar through scraper plate mounting hole.
The pull bar extends downward into the bottom of broach hopper section along bulkhead, and positioned at the top of feed bin bottom plate.
Described scraper plate one end is fixedly connected with pull bar, and the other end extends into feed bin, and the surface of scraper plate vertical ties is set
Put.
The pneumatic hammer includes being arranged on the pneumatic hammer one of broach hopper section bulkhead outside vertical arrangement and installed in taper
The horizontally arranged pneumatic hammer two of hopper section bulkhead exterior bottom.
The pneumatic hammer one includes about two spaced pneumatic hammers；The pneumatic hammer two includes two in same water
The pneumatic hammer being disposed on horizontal line.
The pneumatic hammer one is arranged above and below on the same line；The pneumatic hammer two is located at the bottommost of feed bin side wall, and
It is symmetrical arranged.
Beneficial effect：
By setting the power dredger being arranged in hopper body bulkhead, installed in the pneumatic hammer of hopper body lower part；
First pass through power dredger above hopper body to dredge the position that may easily tie arch in feed bin, in hopper body
The position that may tie arch is further dredged in lower section by the vibrations of pneumatic hammer again, it is ensured that bin blanking is uniform.
Brief description of the drawings
Fig. 1 is the theory structure schematic diagram of the present invention；
Fig. 2 is the part-structure schematic diagram of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention proposes a kind of hopper dredging system；Including hopper body 1, the power in the bulkhead of hopper body 1
Dredger 2, the pneumatic hammer installed in the bottom of hopper body 1；The hopper body 1 includes elevating hopper section 11 and broach hopper section
12, elevating hopper section 11 is connected with broach hopper section 12；The elevating hopper section 11 includes square hopper or circular hopper；It is described
Power dredger 2 is arranged at the inwall of broach hopper section 12；The pneumatic hammer is arranged in the bulkhead of broach hopper section 12
Bottom.
The power dredger 2 includes two dredgers being symmetricly set in the bulkhead of broach hopper section 12.
The power dredger 2 includes hydraulic cylinder 21, pull bar 22 and scraper plate 23；The pull bar 22 passes through connector and liquid
Cylinder pressure 21, which is connected and driven by hydraulic cylinder 21, to be moved back and forth；The matching of scraper plate 23 is arranged on pull bar 21.
The hydraulic cylinder 21 is located at the medium position of the bulkhead of broach hopper section 12, and pull bar 22 extends one from the top down along bulkhead
Fixed distance；Pull bar 22 is formed by steel plate butt welding, and its cross sectional shape is polygon.
Scraper plate mounting hole is provided with the pull bar 22, scraper plate 23 is fixed on pull bar 22 through scraper plate mounting hole.
The pull bar 22 extends downward into the bottom of broach hopper section 12 along bulkhead, and positioned at the top of feed bin bottom plate.
Described one end of scraper plate 23 is fixedly connected with pull bar 22, and the other end extends into feed bin, and the vertical ties 22 of scraper plate 23
Surface set.
The pneumatic hammer includes being arranged on the pneumatic hammer 1 of the bulkhead outside vertical of broach hopper section 12 arrangement and installed in cone
