In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example; The Chinese patent document discloses a kind of novel two-wheel slotter [application number: 200820048822.7]; Comprise leading truck, seal case, drive unit, be installed on can carrying out positive and negative at least one of milling some milling heads that are periphery of digging to soil layer, rock stratum and milling wheel of seal case bottom; Wherein also include the desilt servicing unit, this desilt servicing unit is fixed in the position of seal case bottom near milling head that mills wheel and suction mud mouth.
Such scheme has alleviated to a certain extent that to mill the digging machine maintenance difficulty big, and the problem of sludge discharge effects difference, but it is low still to exist intensity is installed complicatedly, mills and digs tool tip and be prone to produce fracture, the problem of operating efficiency difference.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of simple in structure, easy for installation, the high-intensity digging machine that mills.
For achieving the above object; The utility model has adopted following technical proposal: originally mill digging machine, comprise support and be arranged on the support both sides and the milling of tubular that can under power drive, circumferentially rotate dug head, it is characterized in that; Described milling dug a periphery wall and is provided with some spiral helical baffles; One side of each helical baffle is welded with some tool rests through five road welding manners respectively, and described tool rest is evenly distributed successively, and described tool rest is connected with cutter head through first demountable structure.During work, mill and dig head rotation under power drive, cutter head mills stone or concrete etc. broken; Through helical baffle crushed stone or broken concrete are taken out of, tool rest is welded on to mill through five roads and digs on the head, carries out three roads earlier and confines welding; Carrying out twice welding attractive in appearance; Make tool rest and milling dig between the head and closely connect, be difficult to fracture occur, more firmly more attractive in appearance.
Above-mentioned milling in the digging machine, described first demountable structure comprises the through hole that is arranged on the tool rest, and described cutter head is plugged in the through hole.When tool bit abrasion seriously need be changed, only need old cutter head is taken out from through hole, new cutter head in the replacing makes that the replacing of cutter head is convenient.
Above-mentioned milling in the digging machine, described milling dug head and linked to each other with support through second demountable structure.Install simply, made things convenient for and milled the maintenance and the maintenance of digging head.
Above-mentioned milling in the digging machine, described second demountable structure comprises being arranged on and mills the flange that digs first end, and described flange both sides are respectively equipped with bolt and swivel nut, and described swivel nut digs through being arranged on to mill that packing ring links to each other with frame between head and the frame.Increased water-proof function through flange and packing ring, made to mill and dig an inside and can not get rusty because of water inlet.
Above-mentioned milling in the digging machine, also be connected with mounting seat on the described support, described mounting seat is provided with some installing holes.Originally milling digging machine is installed on the actuating unit through the installing hole on the mount pad.
Compared with prior art, the advantage of originally milling digging machine is: simple in structure, intensity is high, connects between each component closely, is difficult for producing fracture, and efficiency of construction is high, and sludge discharge effects is good, and dismounting is easy to maintenance, working stability.
Description of drawings
The structural representation that Fig. 1 provides for the utility model.
The partial sectional view that Fig. 2 provides for the utility model.
Among the figure, support 1, mill dig 2, helical baffle 21, tool rest 22, through hole 221, cutter head 23, first demountable structure 3, second demountable structure 4, flange 41, bolt 42, swivel nut 43, packing ring 44, mounting seat 5, installing hole 51.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Like Fig. 1, shown in 2; Originally mill digging machine; Comprise that support 1 and milling of the tubular that is arranged on support 1 both sides and can under power drive, circumferentially rotates dig 2, mill and dig 2 periphery wall and be provided with some spiral helical baffles 21 that a side of each helical baffle 21 is welded with some tool rests 22 through five road welding manners respectively; Tool rest 22 is evenly distributed successively, and tool rest 22 is connected with cutter head 23 through first demountable structure 3.During work, mill and dig 2 rotation under power drive, cutter head 23 mills stone or concrete etc. broken; Through helical baffle 21 crushed stone or broken concrete are taken out of, tool rest 22 is welded on to mill through five roads and digs on 2, carries out three roads earlier and confines welding; Carrying out twice welding attractive in appearance; Make tool rest 22 and milling closely connect between digging 2, be difficult to fracture occur, more firmly more attractive in appearance.
