Abstract
The utility model relates to a bucket lip for a drill rod of a breaking hammer. A bucket lip body is an approximately cone body; a working part is arranged at the front end of the bucket lip body; a drill rod insertion cavity is arranged in the bucket lip body; and the horizontal section of the drill rod insertion cavity is round-shaped. The bucket lip for the drill rod of the breaking hammer, which is provided by the utility model, is sleeved on the drill rod of the breaking hammer and is in close fit with the drill rod of the breaking hammer when in use. In the process of carrying out crushing operation, the bucket lip is worn at the beginning and can take a protection effect on the drill rod, so that the service life of the drill rod is prolonged and the working cost is reduced.
Description
Technical field
The utility model relates to a kind of parts of disintegrating machine, is specifically related to the used bucket tooth of crushing hammar drill rod.
Background technology
Present domestic and even various quartering hammers (being commonly called as woodpecker) that produce in the world all adopt superior alloy steel bar finish forge spare, and the drill rod that forges out through repeatedly normalizing, Quenching Treatment carries out work.Though good drill rod long service life, intensity are high, quartering hammer generally all is the running of 24 hours ultra-long times, excess load, under the bad working environments condition.The distortion that the drill rod rate of wear is very fast, have even fracture.At present, a domestic good drill rod price is about 2000 yuan, and import drill rod price reaches more than 3000 yuan, and cost is expensive, if drill rod is scrapped frequently, will increase production cost greatly, and when changing drill rod, must dismantle quartering hammer, and is time-consuming, take a lot of work.
Summary of the invention
To the problem that exists in the prior art, the utility model provides a kind of crushing hammar drill rod bucket tooth, and bucket tooth is sleeved on the crushing hammar drill rod, prolongs the service life of crushing hammar drill rod.
The purpose of the utility model is achieved in that a kind of crushing hammar drill rod bucket tooth, and the bucket tooth body is an approximate circle cone, and bucket tooth body front end is an operate portions, is provided with drill steel in the bucket tooth body and inserts the chamber.The horizontal cross-section that drill steel inserts the chamber is circular.
The crushing hammar drill rod bucket tooth that the utility model provides is sleeved on during use on the crushing hammar drill rod, closely cooperates with crushing hammar drill rod; In carrying out crushing operation, at first wearing and tearing is bucket tooth, and bucket tooth can play a protective role to drill steel; Prolong the service life of drill steel, reduced job costs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the sectional structure chart of the utility model.
Fig. 3 is the structural representation that installs additional behind the drill steel.
Fig. 4 is the A-A cutaway view of Fig. 2.
The specific embodiment
The structure of the utility model is as shown in Figure 1: a kind of crushing hammar drill rod bucket tooth, bucket tooth body 1 are an approximate circle cone, and bucket tooth body 1 front end is an operate portions 4, are provided with drill steel in the bucket tooth body 1 and insert chamber 2.The horizontal cross-section that drill steel inserts chamber 2 is circular.
When the utility model uses, machining is made on drill steel 3 tops, be processed into taper shape; Match with the drill steel insertion chamber 2 of bucket tooth body 1, during use drill steel 3 is sleeved in the drill steel insertion chamber 2 of bucket tooth body 1, need not weld; Vibrations principle according to quartering hammer; Drill steel 3 inserts cooperating along with the motion of drill rod is overlapped tighter and tighter between the chamber 2 with drill steel, can not come off, and substitutes drill steel 3 by operate portions 4 and carries out crushing operation.Bucket tooth through long-time wearing and tearing after, if need to change, only need with suitably beaing the joint portion of bucket tooth body 1 outward with drill steel 3, bucket tooth body 1 is promptly tear-away, need not dismantle quartering hammer drill steel is carried out integral replacing, the saving of labor, save time, laborsaving.As long as drill steel 3 can use; Just only need periodic replacement bucket tooth body; The price of a bucket tooth only accounts for 1/10 of a drill rod cost, and the service life of bucket tooth is almost basic identical with the service life of drill rod, and the bucket tooth inner chamber is little to the drill rod wearing and tearing; Drill rod can use for a long time, greatly reduces production cost.
