Abstract
The utility model discloses a reamer head used for a coarse-pitch cutter suction device. The reamer head is characterized in that a lower disc is welded under reamer arms and an upper disc is welded on the reamer arms; the middle upper part of the upper disc is welded with an upper cover, and 5-6 reamer arms are designed on the reamer head; 5-8 cutter teeth are arranged on each reamer arm; a multiple thread is processed in the upper disc. The reamer head has the advantages of multiple thread, larger screw pitch, quick installation and replacement speed of the reamer head, high efficiency and wide practicability.
Description
Technical field
The utility model relates to a kind of reamer head, refers to especially a kind of coarse pitch 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 and is mostly one start screw with the connecting thread of the upper disk inside on reamer head, and pitch is less, causes the installation of reamer head and replacing speed slower.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of efficient, coarse pitch strand suction device reamer head.
The technical solution of the utility model is: a kind of coarse pitch 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 further improvement of the utility model, on described reamer head, design 5-6 reamer arm; 5-8 cutter tooth is installed on described reamer arm.
As further improvement of the utility model, described lower disc, for circle is with loop configuration, is greater than disk between it;
As further improvement of the utility model, described upper disk inside is processed with 3-4 head thread, and pitch is large.
The beneficial effects of the utility model are: maximum feature of the present utility model is that the connecting thread of the upper disk inside on reamer head is multiple thread, and pitch is larger, the installation of reamer head and replacing speed is fast, efficiency is high.
Brief description of the drawings
Fig. 1 is the sectional view that a kind of coarse pitch strand of the utility model is inhaled device reamer head;
Fig. 2 is that a kind of coarse pitch strand of the utility model 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 utility model is described in further detail.
The structure of a kind of coarse pitch strand of the utility model 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; 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 multiple 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.
