Description
Technical field
This utility model relates to tunneling machine cutting head member, particularly to a kind of helical blade for cutterhead.
Background technology
The cutting head of roadheader of design is the most highly developed at present, but owing to each underground coal mine working condition is complicated, cutterhead cutting efficiency is the highest, during the drilling depth of tunnel, the existence of cutterhead toothholder is the most wear-resisting, broken teeth phenomenon serious, the problems such as inconvenient are changed in down-hole；In addition, traditional cutterhead helical blade design comparison is simple, general helical blade uses general steel plate to make, helical blade uses connecting method, causing resistance in cutterhead cutting course relatively big, the problem that water conservancy diversion has some setbacks, simultaneously because helical blade material is the most wear-resisting, often result in helical blade root area serious wear, even cause toothholder excessive wear serious and drop.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, thus provides a kind of helical blade for cutterhead, and blade significantly improves service life, water conservancy diversion efficiency effectively strengthens, cutting resistance is greatly decreased.
Utility model be employed technical scheme comprise that such: for the helical blade of cutterhead, it is made up of bimetal wear resistant composite material integral formed twist, it includes low-carbon alloy steel layer and is arranged at the chromium carbide wearing layer of described low-carbon alloy steel layer side, described low-carbon alloy steel layer opposite side is provided with some groups of flow-guiding structures, described flow-guiding structure is uniform along the length direction of helical blade, described flow-guiding structure includes baffle and guiding gutter, the length direction of described baffle and described guiding gutter extends along the width of helical blade, the upper surface of described baffle and the bottom land of described guiding gutter is inclined-plane and both are generally aligned in the same plane, all it is crisscross arranged between adjacent described baffle and between adjacent described guiding gutter.
Improve further: described baffle is connected with described guiding gutter.
Improve further: described baffle is crisscross arranged with described guiding gutter, and the length of described baffle and described guiding gutter is all higher than the half of helical blade width.
Improve further: described low-carbon alloy steel layer has insection structure on the contact surface of described chromium carbide wearing layer.
Improve further: the root of described helical blade is provided with antifriction alloy sheet.
By using preceding solution, the beneficial effects of the utility model are:
Made by the bimetal wear resistant composite material integral formed of employing low-carbon alloy steel layer with chromium carbide wearing layer, therefore the wearability of helical blade is good, service life is longer, and guide performance is good, in addition by arranging flow-guiding structure, the intensity of helical blade while improving guide performance further, is ensured.

Fig. 2 is this utility model schematic diagram (embodiment two).
Wherein: 1, low-carbon alloy steel layer；2, chromium carbide wearing layer；3, baffle；4, guiding gutter.
Detailed description of the invention
This utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this utility model discloses a kind of helical blade for cutterhead, it is made up of bimetal wear resistant composite material integral formed twist, it includes low-carbon alloy steel layer 1 and is arranged at the chromium carbide wearing layer 2 of described low-carbon alloy steel layer 1 side, described low-carbon alloy steel layer 1 opposite side is provided with some groups of flow-guiding structures, described flow-guiding structure is uniform along the length direction of helical blade, described flow-guiding structure includes baffle 3 and guiding gutter 4, the length direction of described baffle 3 and described guiding gutter 4 extends along the width of helical blade, the upper surface of described the baffle 3 and bottom land of described guiding gutter 4 is inclined-plane and both are generally aligned in the same plane, all it is crisscross arranged between adjacent described baffle 3 and between adjacent described guiding gutter 4.
By using the bimetal wear resistant composite material integral formed of low-carbon alloy steel and chromium carbide wearing layer 2 to make compared to traditional spliced helical blade sticking on wear-resistant block, its overall performance is good, abrasion resistant effect is good, blade significantly improves service life, water conservancy diversion efficiency effectively strengthens, cutting resistance is greatly decreased, and by arranging flow-guiding structure, guiding gutter 4 and baffle 3, both inclined-planes not only act as good guide functions, and baffle 3 ensure that the bulk strength of helical blade, thus make up and offer the loss of strength that guiding gutter 4 brings.
In embodiment one: described baffle 3 is connected with described guiding gutter 4, the water conservancy diversion inclined-plane that this structure is positioned at guiding gutter 4 due to baffle 3 is connected mutually, thus further increases water conservancy diversion effect.
Embodiment two: as shown in Figure 2, difference with embodiment one is: described baffle 3 is crisscross arranged with described guiding gutter 4, and the length of described baffle 3 and described guiding gutter 4 is all higher than the half of helical blade width, i.e. baffle 3 is different from the mutual alignment of guiding gutter 4, although water conservancy diversion effect does not has in embodiment one strong, but by baffle 3 is crisscross arranged with guiding gutter 4, consequently facilitating processing.
In order to improve the contact area of low-carbon alloy steel layer 1 and chromium carbide wearing layer 2, improving both bond strengths, described low-carbon alloy steel layer 1 has insection structure on the contact surface of described chromium carbide wearing layer 2.
In order to extend the service life of helical blade, the root of described helical blade is provided with antifriction alloy sheet.
Of the present utility model ultimate principle and principal character and advantage thereof have more than been shown and described; skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; above-described embodiment and explanation described in principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications; in the range of these changes and improvements both fall within claimed this utility model, this utility model claims scope and is defined by appending claims and equivalent thereof.
