Abstract
The invention discloses a reamer head for a cutter suction device with graded cutter teeth. The reamer head comprises a lower disc, reamer arms, cutter teeth, an upper disc, an upper cover and a screw thread. The lower parts of the reamer arms are welded with the lower disc, and the upper parts of the reamer arms are welded with the upper disc; the middle upper part of the upper disc is welded with the upper cover, and five to six reamer arms are arranged on the reamer head; five to eight cutter teeth are arranged on each reamer arm; the screw thread is processed in the upper disc. The reamer head has a biggest feature that the conventional method of matching the cutter teeth in one specification for one reamer head is broken by adopting an optimum design method of decreasing the size of the cutter teeth from top to bottom in sequence according to the stress condition of the reamer cutter during rotary working, and the reamer head has the advantages of reasonable design, high efficiency and wide practicability.
Description
Technical field
The present invention relates to a kind of reamer head, refer to especially a kind of cutter tooth gradual change type strand suction device reamer head.
Background technology
Cutter suntion dredger is a kind of dredge boat that excavates and carry earth the most frequently to use, he can dig deeply, widens and clear up original navigation channel and harbour, excavate new navigation channel and harbour, also can be used for excavating the foundation trench of canal, dredger business, ship lock and other hydraulic structures etc. engineering.Growing along with water transportation transport undertaking, cutter suntion dredger has obtained significant progress, has become a kind of important engineering ship.
It is the important component part of cutter suntion dredger that strand is inhaled device, is mainly made up of reamer head, protective cover, rear seal-cover, dredging tube, locating shaft, dredge pump, hydraulic motor, reducer and support etc., and reamer head is made up of reamer arm, upper disk, lower disc and cutter tooth.The work of cutter suntion dredger is to drive reamer head rotary work by hydraulic motor and reducer, and dredging tube reaches the bottom, starts hydraulic motor water-bed silt is stirred into after mud,, is delivered to and is piled up place by pipeline mud sucking-off with dredging tube.Compared with trailing suction hopper dredger, cutter suntion dredger operating efficiency is high, can dredge at the relatively dark bottom.Therefore, strand suction application of installation scope is more extensive.
In prior art, strand is inhaled device has a maximum feature with the cutter tooth on reamer head, is exactly a specification cutter tooth of a reamer head coupling, more convenient in the time producing installation like this; But the force analysis according to reamer head the rotary work time finds, this design is also unreasonable, and reason is stressed larger at the top near reamer head, and stressed less in the bottom of reamer head; If all select cutter tooth according to maximum weighted, certainly will cause cutter tooth to select excessive, cause the material of material and the increase of expense.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of reasonable in design, efficient cutter tooth gradual change type strand and inhale device reamer head.
Technical scheme of the present invention is: a kind of cutter tooth gradual change type strand is inhaled device reamer head, comprises lower disc, reamer arm, cutter tooth, upper disk, upper cover, screw thread.Below described reamer arm, be welded with lower disc, be welded with disk above; Described upper disk middle and upper part is welded with upper cover; Described upper disk middle and upper part is welded with upper cover, can prevent that outside mud from entering disk inside cavity.
As a further improvement on the present invention, on described reamer head, design 5-6 reamer arm.
As a further improvement on the present invention, 5-8 cutter tooth is installed on described reamer arm, and the size of cutter tooth is from upper to successively decreasing successively;
As a further improvement on the present invention, described lower disc, for circle is with loop configuration, is greater than disk between it;
As a further improvement on the present invention, described upper disk inside is processed with screw thread.
The invention has the beneficial effects as follows: maximum feature of the present invention is the stressing conditions the rotary work time according to reamer head, adopt Optimization Design, 5-8 cutter tooth is installed on each reamer arm, and the size of cutter tooth is from upper to successively decreasing successively, break the way of traditional " a specification cutter tooth of a reamer head coupling ", reasonable in design, efficient.
Brief description of the drawings
Fig. 1 is the sectional view that a kind of cutter tooth gradual change type strand of the present invention is inhaled device reamer head;
Fig. 2 is that a kind of cutter tooth gradual change type strand of the present invention is inhaled device reamer head top view.
In figure: 1, lower disc; 2, reamer arm; 3, cutter tooth; 4, upper disk; 5, upper cover; 6, screw thread.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The structure of a kind of cutter tooth gradual change type strand of the present invention suction device use reamer head as shown in Figure 1, comprises lower disc 1, reamer arm 2, cutter tooth 3, upper disk 4, upper cover 5, screw thread 6.Described reamer arm 2 is welded with lower disc 1 below, is welded with disk 4 above; Described reamer arm 2 is provided with 5-8 cutter tooth 3, and the size of cutter tooth 3 is from upper to successively decreasing successively; Described lower disc 1 is for circle is with loop configuration, and its diameter is greater than disk 4; Described upper disk 4 middle and upper parts are welded with upper cover 5; Described upper disk 4 inside are processed with screw thread 6; On described reamer head, design 5-6 reamer arm 2.
When work, external drive is connected with the screw thread 6 of reamer head, drives whole reamer head to drive cutter tooth 3 Rotation Dredging on reamer arm 2, dredges respond well.
