Embodiment Construction

[0019] The present invention can be better understood from the following examples. The present invention will be further explained below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the present invention provides an adjustable coal shoveling plate for the shearer cutting section, comprising a rocker 1 and a coal shoveling plate mechanism of the shearer cutting section, and the coal shoveling plate mechanism consists of a coal shoveling plate 2, The fixed plate 3, the lifting hydraulic cylinder 4, and the tilting hydraulic cylinder 5 are formed, because the structure is flexible, it can be used for cutting rocker arms of any type of shearer. A spherical joint seat 1-1 and a hydraulic cylinder connecting ears 1-2 are additionally installed at the bottom of the cutting rocker arm 1 of the coal shearer.

[0021] Such as figure 1 , figure 2 The two groups of tilting hydraulic cylinders 5 shown are single-control hydraulic cylinders, and ea...

Abstract

An adjustable coal shoveling plate used in the cutting part of a coal shearer is characterized in that it includes a rocker arm and a coal shoveling plate mechanism; the coal shoveling plate mechanism includes a coal shoveling plate, a fixed plate, a set of lifting hydraulic cylinders and a set of The tilt adjustment hydraulic cylinder, the fixed plate and the rocker arm are connected by a ball hinge; the lifting hydraulic cylinder is placed in the installation groove on the fixed plate, one end is fixed with the fixed plate by a pin, and the other end is hinged with the coal shoveling plate; one end of the tilt adjustment hydraulic cylinder It is hinged with the fixed plate, and the other end is hinged with the rocker arm; the coal shoveling plate and the fixed plate form a slide rail slider mechanism; the coal shoveling plate mechanism provided by the invention is easy to install, flexible in structure, and can be applied to any type of coal shearer The rocker arm is cut to realize the automatic cleaning of accumulated coal rocks, which avoids the obstruction caused by the accumulated coal rocks to the shearer, reduces the resistance when the scraper conveyor is pushed forward, and improves the coal loading of the shearer. Effect.

Description

technical field [0001] The invention relates to a coal-shoveling board, in particular to an adjustable coal-shoveling board used for the cutting part of a coal mining machine. Background technique [0002] The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. With the development of the coal industry, the function of the shearer is more and more advanced. However, in the prior art, there are more coal rocks accumulated between the scraper groove of the scraper conveyor of the shearer and the coal wall, which increases the The resistance encountered when the plate conveyor is pushed forward hinders the walking of the shearer. Therefore, how to improve the existing technology to solve the accumulation of coal rock between the scraper and the coal wall, and improve the walking efficiency o...
