Abstract
The invention relates to a densely distributed teeth type rock breaking reamer for a dredge boat, and belongs to the technical field of dredging. The densely distributed cutter teeth type rock breaking reamer is characterized by comprising a hub (2), a cutter ring (3), cutter arms (4), tooth bases (5) and cutter teeth (6), wherein the top hub (2) and the bottom cutter ring (3) are connected into a whole by virtue of centrosymmetric cutter arms (4); two rows of tooth bases (5) are distributed on each spiral cutter arm (4), one row of tooth bases (5) are distributed along the outer profile end (8) of each cutter arm (4), and the other row of tooth bases are distributed on the upper part of the back (9) of each cutter arm; and the cutter teeth (6) are assembled on the two rows of the tooth bases (5). The rock breaking reamer has the advantages of compact assembly, implementation facilitation, low manufacture cost, economy and practicality, high construction efficiency, wide application range and the like, so that the impact to the cutter teeth can be reduced, the torque of a reamer axis can be more stable, and the rock breaking capability of the reamer can be improved.
Description
Technical field
The invention belongs to the dredging technology field, particularly relate to a kind of dredge boat with the broken rock reamer of the cutter tooth type that gathers.
Background technology
At present, the ocean-going freighter tonnage is increasing, absorbs water more and more deeplyer, requires the navigation channel to dig darker and darker.Deep-cut soil property and also more become harder, become the even middle decomposed rock of strong-weathered rock by original mud, clay.Universal reamer can't be tackled the soil property of how many samples now, and also arises at the historic moment for the reamer of different soil properties, wherein digs the lithotype reamer and also emerges in an endless stream.The existing rock reamer that digs has adopted six cutter walls, the form of screw arrangement usually.The rock reamer that digs of this form digs the rock process actual, reamer is stressed not steady, reamer power moment uprushes, and the duration is shorter, and most of the time reamer power moves in lower value, especially when excavating harder rock, this phenomenon is more obvious, this is not in full use with regard to the ability that causes the high-power driving device, causes waste, and production efficiency is low.
By researching and analysing, to find to cause when digging the construction of rock reamer, it is even not that the jiggly reason of digging force is that cutter tooth distributes, and causes the moment impact reamer, it is large that power becomes suddenly, easily causes reamer or device damage, affects the problems such as operating efficiency.
Summary of the invention
The present invention provides a kind of dredge boat to break the rock reamer with the cutter tooth type that gathers for solving the technical problem that exists in known technology.
The objective of the invention is to improve the rock breaking capacity of reamer, reduce the impact force that cutter tooth is subject to, the suffered moment of torsion of mangler shaft is more stable, improves the rock breaking capacity of reamer, have assembling compact, be convenient to realize low cost of manufacture, economical and practical, the characteristics such as efficiency of construction is high, and is applied widely.
The present invention improves on cutter tooth is arranged, changes a former tool arm one row's cutter tooth into a tool arm two row's cutters tooth, increases cutter tooth quantity, and cutter tooth is arranged more even, and moment of torsion is more steady, improves the rock breaking capacity of reamer.
The technical scheme that dredge boat of the present invention is taked with the broken rock reamer of the cutter tooth type that gathers is:
A kind of dredge boat breaks the rock reamer with the cutter tooth type that gathers, it is characterized in that: broken rock reamer comprises wheel hub, cutter ring, tool arm, toothholder and cutter tooth, top wheel hub and bottom cutter ring connect into an integral body by the tool arm that is centrosymmetric, each tool arm is helical form, be furnished with two toothrow seats on tool arm, outline end place along tool arm arranges a toothrow seat, and the tool arm upper rear portion is divided and also arranged a toothrow seat, is equipped with cutter tooth on two toothrow seats.
Dredge boat of the present invention can also adopt following technical scheme with the broken rock reamer of densely covered cutter tooth type:
Described dredge boat is characterized in the broken rock reamer of the cutter tooth type that gathers: the outline end place along tool arm is evenly arranged a toothrow seat, and tool arm back side the first half also is evenly arranged a toothrow seat.
Described dredge boat is characterized in the broken rock reamer of the cutter tooth type that gathers: the cutter tooth crown of the cutter tooth crown at the tool arm back side and the outline end of tool arm coexists on an outline enveloping surface.
Described dredge boat breaks the rock reamer with densely covered cutter tooth type, is characterized in: be provided with screw thread in broken rock reamer wheel shell, screw thread is used for being connected to the crane span structure line shaft, and drive is broken the rock reamer and rotated excavation, fragmentation material under water around the axle center.
Advantage and good effect that the present invention has are:
Dredge boat breaks the rock reamer owing to having adopted the brand-new technical scheme of the present invention with the cutter tooth type that gathers, compared with prior art, the present invention is because cutter tooth is arranged more intensive, cutter tooth is more even with contacting of excavation material, so the impact that single cutter tooth is subject to is less, and the suffered moment of torsion of reamer rotating shaft is also just more steady, is conducive to so the broken rock of reamer, improve strand and inhale the rock breaking capacity of ship, construction production can bring huge economic benefit.
