Abstract

The utility model relates to a multi-tooth head cutting pick used for a mining machine, which comprises alloy head conical heads 1, a cutting pick body 3 and a cutting pick body handle 4; and the multi-tooth head cutting pick is characterized in that the alloy head conical heads 1 are evenly distributed and fixed on the cutting pick body 3. The cutting pick with high production and high efficiency reduces the cutting resistance, saves energy, prolongs the service life and is particularly suitable for mining the hard formation.

Description

Multiple tooth mining machinery pick

Technical field

The utility model belongs to a part of mining machinery, particularly a kind of multiple tooth mining machinery pick.

Background technology

The pick that at present domestic and international mining machinery uses, be circular cone alloy head pick type tooth, each pick has only a carbide button head, because the length that the alloy head exposes is little, can not satisfy the needs of big depth of cut, the pick body also will participate in cut when depth of cut is spent greater than the alloy head length; And denticle is a big cone, does not have blade, so cutting resistance is big, and quick abrasion, calorific value height, so that denticle occurs and melted and can not use has a strong impact on application life, and particularly when the high rock stratum of cut hardness, this problem is more outstanding; Simultaneously, because depth of cut is little, the output of coal and lump coal rate and efficient are low.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of cutting resistance little, efficient height, long service life, but multiple tooth mining machinery pick of cut hard formation.

The technical scheme that the utility model technical solution problem is adopted is: a kind of multiple tooth mining machinery pick, comprise alloy head nose cone, pick body and pick body handle, and it is characterized in that the fixing a plurality of alloy head nose cones that on the pick body, evenly distribute.

The beneficial effects of the utility model are: this pick has increased the pick width, makes adjacent two-section line overlap, and several alloy heads were finished before and after the task of an alloy head was dispersed into, and had reduced the depth of cut of each alloy head.Because square being directly proportional of the cutting resistance of tapered tooth head and depth of cut, as if half is fallen in depth of cut, then drag overall also reduces half; Carbide button head in front has also opened the scope of freedom out-of-the-way for the carbide button head of back with regard to a tooth, has reduced cutting resistance again, so, the bull tooth can not only prevent to grind the pick body, and can reduce cutting resistance significantly, saves energy, improve the application life of pick, high-yield and high-efficiency.Be particularly suitable for the digging hard formation.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is a multiple tooth mining machinery pick front view;

Fig. 2 is the left side view of Fig. 1;

Among the figure: 1-alloy head nose cone; 2-cylinder nose cone body; 3-pick body; 4-pick body handle.

The specific embodiment

Embodiment, with reference to accompanying drawing, a kind of multiple tooth mining machinery pick comprises alloy head nose cone 1, pick body 3 and pick body handle 4 is characterized in that fixing four alloy head nose cones 1 pick body 3 even distributions.Pick body 3 and pick body handle 4 evenly are distributed with four holes for one processes on the pick body 3 left end women's head-ornaments; Alloy head nose cone 1 welds together with cylinder cone 2, and cylinder nose cone body 2 tight fits are welded in the hole of pick body 3, and the number of alloy head nose cone 1 can be decided according to the character of coal petrography.

This pick is specially adapted to the cut hard formation.

Claims

1. multiple tooth mining machinery pick comprises alloy head nose cone (1), and pick body (3) and pick body handle (4) is characterized in that going up the fixing a plurality of alloy head nose cones (1) that evenly distribute at pick body (3).
