Description

Spherical composite cutting pick

Technical Field

The utility model discloses a belong to mine coal mining, tunnelling, tunnel excavation equipment coal-winning machine, cutter technical field for the entry driving machine, specifically relate to a spherical compound pick.

Background

The cutting pick is widely applied to coal mining machines and heading machines in the fields of tunnel excavation, mine roadway tunneling, coal mining and the like, is tooth and claw of the heading machines and the coal mining machines, is easy to wear and has large using amount. The traditional cutting pick consists of a pick head, a main tooth brazed on the pick head, a pick handle and a tubular retainer ring. In operation, the main tooth cuts rock (coal) under the protection of the tooth head. The tooth head is made of high-quality alloy steel, and when the tooth head meets rocks, the tooth head is worn quickly. After the tooth head is worn, the protection effect on the main tooth is lost, the main tooth is broken and falls off due to the loss of protection, so that the cutting tooth loses the cutting edge and cannot continuously cut rocks, and sometimes, the cutting tooth needs to be replaced for several times in each shift, so that the labor intensity is high, the production efficiency is low, and the production cost is high. In order to solve the problem of wear resistance of the pick head, various pick production manufacturers also adopt various improved schemes, one of the schemes is to alternately arrange the tooth-shaped teeth on the outer circumference of the pick head, and the scheme can solve the problem of wear resistance of the outer circumference of the pick head but cannot protect the periphery of the main teeth on the end face of the pick head.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a purpose is: the cutting pick overcomes the defects that the existing cutting pick bit is easy to wear and lose the protection effect on the main tooth, the main tooth is easy to break and fall off, the cutting pick loses the cutting edge and cannot continuously cut rocks, the labor intensity is high, the production efficiency is low, the production cost is high, and the periphery of the main tooth of the end face of the bit head cannot be protected. The spherical composite cutting pick has the advantages that the periphery of the main tooth of the end face of the pick head is effectively protected, the main tooth is not easy to break and fall off, the labor intensity is low, the production efficiency is high, and the production cost is low.

The utility model discloses a technical scheme who adopts for solving above-mentioned technical problem is: this spherical compound pick mainly comprises tooth head, toothholder, main tooth, profile of tooth and tubulose retaining ring, its characterized in that: the main teeth are brazed in the main tooth holes of the tooth heads; the tooth-shaped teeth are distributed in the tooth-shaped tooth holes at the periphery of the tooth head in a staggered manner; the tubular retainer ring is arranged on the gear handle; the tooth head is also provided with a plurality of auxiliary teeth which are embedded in auxiliary tooth holes uniformly distributed around the main teeth at the front end of the tooth head.

The utility model discloses a beneficial effect is: the spherical composite cutting pick with the structure is characterized in that the pick head is provided with a plurality of auxiliary teeth, the auxiliary teeth are embedded in auxiliary tooth holes uniformly distributed around the main tooth at the front end of the pick head and are distributed in 9-12 tooth-shaped teeth on the periphery of the pick head in a staggered manner with the main tooth, a similar spherical drill bit is formed, the pick head and the main tooth are protected in an all-round manner, the problem that the main tooth is broken and falls off due to the fact that the pick head is extremely easy to wear is solved, further, the cutting pick fails is achieved through the auxiliary teeth and the tooth-shaped teeth, and the impact resistance and the wear resistance of the cutting pick are improved. This spherical compound pick has improved the life of pick, and the contrast test improves more than 20% than the pick life-span of scheme production, improves more than 50% than traditional pick life-span, and manufacturing cost effectively reduces, and production efficiency also improves by a wide margin. The gear head has the characteristics that the periphery of the main gear of the end face of the gear head is effectively protected, the main gear is not easy to break and fall off, the labor intensity is low, the production efficiency is high, the production cost is low, and the like.

As the utility model discloses an improvement, vice tooth be 6-9, inlay in the vice tooth hole of equipartition around the tooth head front end owner tooth, can effectively improve the rotation ability and the wear resistance of pick.

fig. 2 is a right sectional structure view of the first embodiment of the spherical composite cutting pick of the present invention shown in fig. 1.

In the figure, 1, a main tooth, 2, a main tooth hole, 3, an auxiliary tooth hole, 4, an auxiliary tooth, 5, a tooth-shaped tooth, 6, a tooth-shaped tooth hole, 7, a tooth head, 8, a tooth handle, 9 and a tubular retainer ring.

Detailed Description

The spherical composite cutting pick of the present invention is further described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the spherical composite cutting pick mainly comprises a pick head 7, a tooth handle 8, a main tooth 1, a tooth-shaped tooth 5 and a tubular retainer ring 9, and is characterized in that: the main tooth 1 is brazed in the main tooth hole 2 of the tooth head 7; the tooth-shaped teeth 5 are distributed in tooth-shaped tooth holes 6 at the periphery of the tooth head 7 in a staggered manner; the tubular retainer ring 9 is arranged on the gear handle 8, so that the connection with a working host machine is facilitated; the tooth head 7 is also provided with a plurality of auxiliary teeth 4, and the auxiliary teeth 4 are embedded in auxiliary tooth holes 3 uniformly distributed around the main tooth 1 at the front end of the tooth head 7.

Adopt the spherical composite pick of above-mentioned structure, be equipped with a plurality of secondary tooth 4 on the pick head 7, this secondary tooth 4 is inlayed in the auxiliary tooth hole 3 around the equipartition 7 front end primary tooth 1, with primary tooth 1 and crisscross 9-12 profile of tooth (5) of distributing in the pick head periphery, constituted and is similar to spherical drill bit, to pick head 7, primary tooth 1 has formed the omnidirectional protection, solved the pick head 7 and easily worn and torn and cause the primary tooth 1 broken, drop, and then lead to the problem that the pick became invalid, secondary tooth 4 still plays the effect of cutting broken rock with profile of tooth 5, the impact resistance and the wearability of pick have been improved. This spherical compound pick has improved the life of pick, and the contrast test improves more than 20% than the pick life-span of scheme production, improves more than 50% than traditional pick life-span, and manufacturing cost effectively reduces, and production efficiency also improves by a wide margin. The protective device has the characteristics that the periphery of the main tooth 1 on the end face of the tooth head 7 is effectively protected, the main tooth 1 is not easy to break and fall off, the labor intensity is low, the production efficiency is high, the production cost is low, and the like.

As the improvement of the utility model, as shown in figure 1, the auxiliary teeth 4 are 6-9, are inlayed in the auxiliary tooth hole 3 around the equipartition 7 front end main teeth 1 of tooth head, can effectively improve the rotation ability and the wear resistance of pick.
