Abstract
The utility model discloses a pickaxe-shaped cutting pick used for mineral industry, which comprises a pick handle and a pick head. The pick head is positioned at the front end of the pick handle and integrated with the pick handle as a whole. A tapered alloy head is arranged at the front end of the pick head and cast with the pick head as a whole. An annular groove is formed on the pick handle. A retainer ring is arranged outside the annular groove. The pickaxe-shaped cutting pick has the advantages of good toughness, small shock resistance, no risk of damage and capability of increasing the mining efficiency.
Description
Technical field:
The utility model relates to a kind of pick, especially relates to a kind of pick shape mining pick.
Background technology:
The colliery is coal industry coal-winning machine, development machine with pick, the a large amount of a kind of attrition components that use of production equipments such as coal plough, often occur in practice, because of the alloy head of existing pick collapses easily, hardness increases, toughness reduces, fracture easily, thus shortened the application life of pick greatly, and ten thousand tons of consumptions are very big, cause the Coal Production cost to increase, make and produce and profit decline.
The utility model content:
The purpose of this utility model is to provide a kind of good toughness, a kind of pick shape mining pick that the product shock resistance is little.
The purpose of this utility model is implemented by following technical scheme: a kind of pick shape mining pick includes the tooth handle, the tooth head, described tooth head is at the front end of described tooth handle, be structure as a whole with described tooth handle, at described tooth head front end is taper alloy head, with the described tooth head structure that is cast as one, one section toroidal cavity is arranged on described tooth handle, outside described toroidal cavity collar.
Advantage of the present utility model is: good toughness, the product shock resistance is little, and is not fragile, adopts this pick shape mining pick, improved coal mining efficient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Tooth handle-1, tooth head-2, taper alloy head-3, toroidal cavity-4, collar-5.
The specific embodiment:
As shown in Figure 1, a kind of pick shape mining pick includes tooth handle 1, tooth head 2, tooth head 2 is structure as a whole with tooth handle 1 at the front end of tooth handle 1, is taper alloy head 3 at tooth head 2 front ends, with tooth head 2 structure that is cast as one, one section toroidal cavity 4 is arranged on tooth handle 1, outside toroidal cavity 4 collar 5.
