Abstract
The utility model relates to a damping dust-falling pick-like bit, belonging to the technical field of coal mining and digging; the pick-like bit comprises a bit body and a rigid alloy head hard-soldered at the end part of the bit body; the surface of the bit body (1) is bead-welded with wear-resisting impact-resistance point alloy (3) which is uniformly distributed along the axial and circumferential direction of the bit body 1. The arrangement of the point alloy (3) has the function of wear resistance, and the protection to the rigid alloy head is enhanced on one hand, and has good damping and impact-resistant functions in the digging or coal mining process of the bit.
Description
Technical field
The utility model belongs to coal mining, digging technology field, relates to a kind of have certain vibration damping, high abrasion, pick-like bit that the coal cutting ability is strong.
Background technology
At present the pick major part used of coal development machine and coal-winning machine is an alloy steel-tooth body and at carbide alloy cylinder of end soldering.Development machine and coal winning machine cutting bit ubiquity pick tooth body first half wear no resistance at present, and hard alloy head easily comes off, and impact resistance is poor, service time is short, change frequently, the digging labor strength is big, changes the pick potential danger and reaches defectives such as digging fittings consumption cost height more.
The utility model content
The purpose of this utility model has been to overcome the above-mentioned defective of existing pick, provides a kind of high abrasion shock-resistant pick-like bit, and this pick has advantages such as the vibration of the pick of reduction, impact resistance, abrasive wear resistance and long service life.
To achieve these goals, the utility model has been taked following technical scheme.The shock-resistant pick-like bit of high abrasion in the utility model comprises pick tooth body and is fixed on the hard alloy head of pick tooth body end.The surface overlaying of described pick tooth body has the point-like alloy of wear and shock-resistant.
Described point-like alloy axially and is circumferentially evenly arranged along pick tooth body.
The beneficial effects of the utility model are:
1) the utlity model has superpower abrasion resistance, certain vibration damping and excellent shock resistance, in use than 9～12 times of the long service life of original pick, be applicable to various in cherry coals, rock stratum driving and exploitation, also be applicable to mine, tunnel, highway, bridge, railway excavation, split etc.
2) the utility model has improved the operating efficiency of coal driving, exploitation.Because the prolongation greatly in application life has greatly reduced the time that flight-line maintenance and pick are changed, reduced working strength of workers and maintenance order of classes or grades at school significantly, thereby improved 3～5 times coal mining efficient.
3) dots structure can reduce the suffered vibration of tooth body, and taps out lumped coal more, reduces the coal dust amount that produces in the manufacturing process, has improved condition of work.
4) improve driving, production efficiency, thereby reduced the coal production cost.
Description of drawings
Fig. 1 point-like built-up welding strengthened pick schematic diagram
Among the figure: 1, pick tooth body, 2, hard alloy head, 3, the point-like alloy.
The specific embodiment
The utility model is described in further detail below in conjunction with Fig. 1:
As shown in Figure 1, this damping depositing dust pick-like bit comprises pick tooth body 1 and the soldering hard alloy head 2 in pick tooth body 1 end, adopts the bead-welding technology built-up welding that the impact-resistant point-like alloy 3 of high abrasion is arranged on pick tooth body 1 surface.Because pick is in when work, axially and radial force big, for preventing coming off of pick tooth body 1 end wear and hard alloy head 2, pick tooth body 1 employing 35CrMo structural alloy steel in the present embodiment.Point-like alloy 3 in the distribution situation on pick tooth body 1 surface as shown in Figure 1, point-like alloy 3 axially and axially evenly distributes along pick tooth body 1.The setting of point-like alloy number is decided as the case may be.
The shock-resistant point-like alloy 3 of high abrasion in the present embodiment is rich chromium cast irons, and nascent eutectic phase and chromium carbide disperse distribute, and have excellent abrasive wear resistance performance.
Point-like alloy 3 in the present embodiment has played excellent wear-resisting effect on the one hand, has increased the protection to hard alloy head 2; When pick driving or coal mining, better vibration damping and shock resistance effect have been played on the other hand.
Claims (2)
1, a kind of damping depositing dust pick-like bit comprises pick tooth body (1) and is fixed on the hard alloy head (2) of pick tooth body (1) end that it is characterized in that: the surface overlaying of described pick tooth body (1) has the point-like alloy (3) of wear and shock-resistant.
2, a kind of damping depositing dust pick-like bit according to claim 1 is characterized in that: described point-like alloy (3) axially and is circumferentially evenly arranged along pick tooth body (1).
