Embodiment Construction
[0012] Such as figure 1 As shown, a non-helical cutting drum has a structure including a drum cylinder 1, a blade 5, a tooth seat 2, and a pick 3. The blade 5 is located on the peripheral side of the drum cylinder 1 and has a closed ring shape. The seat 2 and the pick 3 are evenly distributed on the outer edge of the blade 5, such as figure 2 As shown, ribs 4 are axially provided between the blades 5, and the picks 3 on adjacent blades 5 are arranged in a staggered manner.

The invention relates to a cutting drum of a coal drum shearer, in particular to a non-spiral cutting drum. The non-spiral cutting drum solves the problems that the existing cutting drum adopts a spiral structure, so that the body is severely impacted by coal, and the like, and comprises a drum body, blades, tooth holders and cutting teeth; wherein the blades are positioned on the periphery of the drum body and take the shape of closed rings; the tooth holders and the cutting teeth are uniformly distributed at outer edges of the blades; strengthening ribs are arranged among the blades; and the cutting teeth on adjacent blades are arranged in a staggered way. The cutting drum can be widely applied to various types of domestic low seam coal cutters, realizes energy green and saving exploitation in identical conditions, prolongs the total service life, and enhances the reliability and the stability.
Description
Technical field [0001] The invention relates to a coal shearer drum, in particular to a non-spiral cutting drum. Background technique [0002] The shearer is the key equipment of the fully mechanized mining face, and the drum is the most direct executive element that realizes the functions of the shearer for cutting and loading coal. Spiral drums are used in all kinds of thin coal shearers in China. The main features of the cutting drum of the existing shearer are that it consists of a drum body, picks, tooth seats, nozzles, etc. The drum body is welded The structure adopts three-head or four-head spiral blades. The blades are equipped with internal spray water channels, and high-pressure nozzles, picks, and tooth seats are installed on the spiral blades. The coal loading effect is not ideal. Basically, the cut coal is loaded through natural flow and push conveyors. [0003] In the thin coal seam face, especially in the ultra-thin coal seam face, the coal loading problem of the t...
