Abstract
The utility model relates to a split pick-type bit, which is used for coal miners, and comprises a bit body (1) and a bit head (2). The bit body (1) and the bit head (2) are made of alloy steel materials, a bit head hole (3) is arranged on the top of the bit body (1), the bit head (2) is connected onto the bit body (1), and a carborundum layer is covered on the outer surface of the bit head (2). The split pick-type bit can enhance abrasive resistance of the bit head.
Description
(1) technical field
The utility model relates to a kind of pick-shaped cutter, especially relates to a kind of split type pick-shaped cutter, is used for the coal mining machine.
(2) background technology
Coal-winning machine is that necessary tool is gathered in a kind of colliery, carries out excavation to coal petrography by the cutting that is fixedly installed in the pick on the coal-winning machine.Existing pick structure generally is made up of pick body and tooth head, and the soldering of tooth head is at the top of pick body.Because in the mining process of coal petrography, the tooth head is as main force part, serious wear is often damaged under the still unworn situation of pick body in advance, makes whole pick scrap, thereby has increased the turnover rate of pick, has increased mining costs.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of split type pick-shaped cutter that can increase tooth head abrasion resistance is provided.
The purpose of this utility model is achieved in that a kind of split type pick-shaped cutter, include pick body and tooth head, described pick body and tooth head are the alloy steel material, and pick body top is provided with a gear head hole, described tooth head is connected on the pick body, and described tooth head external surface is coated with one deck Buddha's warrior attendant layer of sand.
The beneficial effects of the utility model are:
Because diamond dust is the material of hardness maximum in the known substance, thereby, can strengthen the abrasion resistance of tooth head greatly, prolong pick application life by at tooth head outer wrapping one deck diamond dust.
(4) description of drawings
Fig. 1 is the utility model structural representation.
Among the figure:
Pick body 1, tooth head 2, gear head hole 3, Buddha's warrior attendant layer of sand 4.
(5) specific embodiment
Referring to Fig. 1, the utility model relates to a kind of split type pick-shaped cutter, include pick body 1 and tooth head 2, described pick body 1 and tooth head 2 are the alloy steel material, pick body 1 top is provided with a gear head hole 3, described tooth head 2 external surfaces are coated with one deck Buddha's warrior attendant layer of sand 4, and described tooth head 2 is connected on the pick body 1.
Claims (1)
1. split type pick-shaped cutter, include pick body (1) and tooth head (2), described pick body (1) and tooth head (2) are the alloy steel material, pick body (1) top is provided with a gear head hole (3), described tooth head (2) is connected on the pick body (1), it is characterized in that: described tooth head (2) external surface is coated with one deck Buddha's warrior attendant layer of sand (4).
