Rocker-type transverse shearer

Abstract

The invention provides a rocker-type transverse shearer. The shearer comprises a machine body consisting of a plurality of case separation cavities, and a power transmission chain, a rocker, a roller and a coiling block which are respectively arranged inside the case separation cavities, wherein a sliding board is arranged at the lower part of the machine body; and the power transmission chain comprises a main transmission wheel connected with a motor spindle and a pair of secondary transmission wheels which are engaged with one another for driving front and back vertical transmission shafts to output power so as to drive a last-stage transmission gear shaft, a roller on a gear shaft of a speed-reducing transmission box, a chain wheel transmission device and cutting teeth to run synchronously. Therefore, a technical scheme of transverse full-section no-dead-angle all-dimensional coal mining is realized. The rocker-type transverse shearer can overcome the defects that the conventional coal mining device can be only used for exploiting coal layers on the top face and the lateral face of a small-dip roadway structure while coal layers between two rollers cannot be synchronously exploited, solves the difficult problem that coal layers on the bottom face of the structure with a roadway dig being more than 25 degrees and coal layers between the two rollers are abandoned without exploitation, is applicable to exploitation of the coal layer on the bottom face of the roadway dig structure of a coal mine, and is particularly applicable to the full-section no-dead-angle all-dimensional exploitation of the coal layer on the bottom face of the structure with the roadway dig being more than 25 degrees and thin coal layers of mediate and small-sized coal mines.

Description

technical field [0001] The invention relates to a rocker type transverse drum shearer. Background technique [0002] The number of existing small and medium-sized coal mines accounts for more than 90% of the total number of coal mines in the country, but the mining scale is small, the mining roadways are narrow, and the technical equipment is backward. Some coal mines even still use pneumatic picks for manual mining, and their coal mining efficiency is low. , the working environment is harsh, and personnel safety is even more difficult to guarantee; and it is even more helpless to mine the bottom coal seam of the steeply inclined roadway structure, resulting in a serious waste of a large amount of coal resources. It is a big problem; while mechanized coal mining has been fully used in small and medium-sized coal mines, the coal mining equipment is only suitable for mining the coal seam at the bottom of the roadway structure with a small inclination angle, and the inclination...

[0002] The number of existing small and medium-sized coal mines accounts for more than 90% of the total number of coal mines in the country, but the mining scale is small, the mining roadways are narrow, and the technical equipment is backward. Some coal mines even still use pneumatic picks for manual mining, and their coal mining efficiency is low. , the working environment is harsh, and personnel safety is even more difficult to guarantee; and it is even more helpless to mine the bottom coal seam of the steeply inclined roadway structure, resulting in a serious waste of a large amount of coal resources. It is a big problem; while mechanized coal mining has been fully used in small and medium-sized coal mines, the coal mining equipment is only suitable for mining the coal seam at the bottom of the roadway structure with a small inclination angle, and the inclination angle of the roadway is generally in the range of 18-25°; and the coal mining equipment between the two drums It will leave a dead angle that cannot be mined; and for the bottom coal seam structure with a large roadway inclination angle, this coal seam structure accounts for a large proportion in the small and medium-sized coal mines in the south. °; for the roadway coal seam structure with an inclination angle above 25°, there is currently no effective coal mining machinery and equipment that can be popularized and used; in addition, although the small coal cutter can adapt to the coal seam structure with an inclination angle above 25°, it can only mine the side of the roadway There are no effective implementation measures for the development of the bottom coal seam with a large roadway inclination angle, so manual mining can only be used, which seriously affects the mining efficiency, has serious safety hazards, and seriously hinders resource-saving and coal resource development and protection strategies implement
