Problems solved by technology

[0002] Shearer spiral drum is a key component of the coal shearer, and its design quality directly affects the coal mining efficiency of the fully mechanized mining unit. The traditional shearer spiral drum includes a drum body and a combined helical blade set on the drum body. As well as the combined picks installed on the spiral blades, the traditional combined picks are mostly flat structures, so that during the working process of the shearer, the coal mined is mostly coal powder, resulting in low mining efficiency and high cost

Embodiment Construction

[0014] Please refer to figure 1 and figure 2 As shown, figure 1 It is a side view of the spiral drum of the shearer of the present invention; figure 2 It is a cross-sectional view of the pick of the spiral drum of the shearer of the present invention. In this embodiment, the spiral drum of the shearer includes a drum body 1, a combined spiral blade 2 arranged on the drum body 1, and a conical tooth seat 3 is installed on the spiral blade 2; 4 includes a rack 40 and a tooth head 42 arranged at one end of the rack 40. The tooth head 42 has a conical structure, and the front end of the tooth head 42 is welded with a conical alloy head 43, the welding strength is greater than 490MPa, so The tapered pick 4 is installed on the tapered gear seat 3 through the gear sleeve 41 with a gear rod 40.

[0015] The spiral drum of the above-mentioned shearer adopts conical picks, and the front end of the conical picks is welded with a conical alloy head, so that when the shearer is mining coa...

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 [0001] The invention relates to a shearer, in particular to a spiral drum of the shearer. Background technique [0002] The spiral drum of the shearer is a key component of the shearer. The quality of its design directly affects the coal mining efficiency of the fully mechanized mining unit. The traditional spiral drum of the shearer includes a drum body and combined spiral blades arranged on the drum body. As well as the combined picks installed on the spiral blades, the traditional combined picks are mostly of flat structure, so that during the working process of the shearer, most of the coal mined is pulverized coal, resulting in low mining efficiency and high cost. Summary of the invention [0003] The purpose of the present invention is to provide a spiral drum of a shearer, which has the characteristics of simple structure, high mining efficiency and low cost. [0004] The purpose of the present invention is achieved through the following technical solutions: ...
