Abstract
The invention discloses a helical shearer roller. The roller comprises a roller body and combined helical blades arranged on the drum body, wherein pick seats are installed on the helical blades; cutting picks are installed on the pick seats through pick sleeves; the cutting picks comprise rods and heads arranged at one ends of the rods; the heads are of a conical structure; and conical alloy heads are welded at the front ends of the heads. The roller has the following beneficial effects: the heads of the cutting picks of the roller are of a conical structure and the conical alloy heads are fixed at the front ends of the heads, so the mined coal is briquette when the shearer with the cutting picks of such a structure is adopted for mining; and the roller not only has a simple structure but also has high mining efficiency, thus relatively lowering the mining cost.
Description
Technical field
The present invention relates to a kind of coal-winning machine, especially relate to a kind of Shearer Helical Drum.
Background technology
Shearer Helical Drum is the critical component of coal-winning machine, the quality of its designing quality directly has influence on combines the coal mining efficient of adopting unit, traditional Shearer Helical Drum comprises barrel, be arranged at the combined helical blade on the barrel and be installed on combination pick on the helical blade, traditional combination pick mostly is flat structure, like this coal-winning machine in the course of the work, the coal of exploitation mostly is coal dust, cause production efficiency low, the cost height.
Summary of the invention
The object of the present invention is to provide a kind of Shearer Helical Drum, it has simple in structure, the characteristics that production efficiency height and cost are low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of Shearer Helical Drum, it comprises barrel, be arranged at the combined helical blade on the barrel, on the described helical blade toothholder is installed, described pick is installed on the toothholder by the tooth cover, wherein, and the tooth head that described pick comprises ratch and is arranged at ratch one end, described tooth head is a conical structure, and the leading section of tooth head is fixed with conical alloy head.
Especially, described alloy head is fixedly welded on the leading section of tooth head.
Especially, the weld strength of described alloy head is greater than 490MPa.
Beneficial effect of the present invention is, the tooth head of the pick of described Shearer Helical Drum is a conical structure, and the leading section of tooth head is fixed with conical alloy head, the coal-winning machine that adopts this kind structure pick is when mining, the coal of exploitation is block, not only simple in structure, and the production efficiency height, mining costs reduced relatively.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the lateral view of Shearer Helical Drum of the present invention;
Fig. 2 is the sectional drawing of the pick of Shearer Helical Drum of the present invention.
Among the figure:
1, barrel; 2, helical blade; 3, taper toothholder; 4, conical pick; 40, ratch; 41, tooth cover; 42, tooth head; 43, alloy head.
The specific embodiment
Please refer to Figure 1 and Figure 2, Fig. 1 is the lateral view of Shearer Helical Drum of the present invention; Fig. 2 is the sectional drawing of the pick of Shearer Helical Drum of the present invention.In present embodiment, described Shearer Helical Drum comprises barrel 1, be arranged at the combined helical blade 2 on the barrel 1, on the described helical blade 2 taper toothholder 3 is installed, the tooth head 42 that described conical pick 4 comprises ratch 40 and is arranged at ratch 40 1 ends, described tooth head 42 is a conical structure, and the leading section of described tooth head 42 is welded with conical alloy head 43, weld strength is greater than 490MPa, and described conical pick 4 utilizes ratch 40 to pass tooth cover 41 and is installed on the taper toothholder 3.
The employing conical pick of above-mentioned Shearer Helical Drum, and the tooth head leading section of conical pick is welded with conical alloy head, and coal-winning machine is when mining like this, and the coal of exploitation be bulk, and is not only simple in structure, and the production efficiency height, reduced mining costs relatively.
