Problems solved by technology

Due to the repeated planing of the compacted area on the coal wall, the force of the planer will increase, and the planing resistance of the planer to the coal wall will be increased, which will reduce the service life of the planer, thereby reducing the efficiency of coal plowing, and the lump coal The rate of formation will also decrease

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] The basic idea of ​​the present invention is to design a plow head with asymmetric blade shape and a coal plow with the plow head, so that the long planer and short planer located on the same plowing stroke route are arranged laterally at intervals. This can not only improve the ability of...

Abstract

The invention discloses a coal planer and a plane head thereof as well as an asymmetrical coal plough method. A long plane cutter and a short plane cutter are asymmetrically arranged on a frame of the plough head of the coal plane, wherein the long plane cutter and the short plane cutter which are on the same coal plough stroke route are transversely arranged at intervals. According to the asymmetrical coal plough method, the coal planer with the plane head is adopted, and the long plane cutter and the short plane cutter are used for alternatively ploughing coal seams in a feed coal plough stroke and a return coal plough stoke. Therefore, the capacity of plough hard coals and the efficiency of plough coals of the coal planer can be improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a coal plow, its plow head, and an asymmetric coal plowing method. Background technique [0002] Generally speaking, a coal plow mainly includes a plow head, a transmission system, a carriage, a scraper conveyor and other components. Wherein, the planer head includes: a planer base, a middle heightening block, a top heightening block and a movable knife rest positioned at the top, and a knife rest is evenly distributed on the planing base, the middle heightening block, and the top heightening block. Each knife holder is provided with a planer. At present, the planers of the planer head of the coal plow mainly adopt a symmetrical installation arrangement. [0003] For example, the same type of planer is installed symmetrically at the same horizontal position, that is, if a long planer is installed on one side of the planer head, the long planer is installed symmetrically at ...
