Abstract
The invention discloses a drum shearer cutting part which comprises a rocker arm shell, a cutting motor, a rocker arm speed reduction box, a planetary gear mechanism and a cutting drum, wherein the cutting motor is directly and transversely arranged in the rocker arm shell, and the motor is fixed in the rocker arm shell through a bolt. A cutting part mechanical transmission comprises a rocker arm speed reduction box and a planetary gear speed reduction mechanism which are independent transmission parts. When a hard waste rock clamping coal bed shearer cutting part works, an output shaft of the cutting motor transmits power to the rocker arm speed reduction box, the power is transmitted to the cutting drum after subjected to speed reduction through a five-grade cylindrical gear and the planetary gear transmission, the cutting drum is linked with an output shaft of the planetary gear speed reducer by adopting a square connecting sleeve, with the advantages of reliability in linkage and convenience for disassembly. The cutting part has a simple and compact integral structure, strong exploitation capacity due to the adoption of the special strong hard waste coal bed clamping coal bed cutting drum, can be used for exploiting a waste coal clamping coal bed with a coal rock firmness exploitation efficiency f of less than 6 and meets the demands of exploitation of an underground hard waste coal clamping coal bed, thus the exploitation efficiency of the hard waste coal clamping coal bed and the exploitation recovery rate of coal resources are increased.
Description
Technical field
The present invention relates to a kind of winning machine cutting part, especially a kind of exploitation slicing portion of drum shearer that is applicable to hard dirt band coal seam, colliery.
Background technology
China is maximum in the world coal production Guo He country of consumption, and along with economic growth, the demand of coal is increasing.Due to China's geological structure more complicated, coal is generally poor, and the proportion in dirt band coal seam, hard dirt band coal seam is larger, and production ratio is more difficult, and the waste of coal resources, because technical reason fails to be exploited and utilize, has been caused in many hard dirt bands coal seam.At present general drum shearer cylinder is cylindrical, is welded with helical blade on cylinder, and integral rigidity, strength deficiency, be difficult to realize the exploitation in dirt band coal seam.In order to guarantee the sustainable development of coal resources in China, exploitation locked middlings is reasonable, an effective approach.Therefore, need to develop in a hurry hard dirt band coal seam production technique, develop a kind of novel hard dirt band coal seam cutting mechanism.
Summary of the invention
Technical problem: the object of the invention is to overcome the deficiency in prior art, propose a kind of compact conformation, can be to the hard dirt band seam mining in down-hole slicing portion of drum shearer.
Technical scheme: slicing portion of drum shearer of the present invention, comprise rocking arm housing, cutting motor, rocking arm reduction box and cutting drum, described cutting drum comprises truncated cone-shaped barrel, be spiral of Archimedes shape is arranged in the pick-shaped cutter on truncated cone-shaped barrel, and pick-shaped cutter is fixed on barrel by pick box; Described cutting motor is directly laterally arranged in rocking arm housing, cutting motor is connected with the power shaft of rocking arm reduction box; rocking arm reduction box is slowed down by level Four roller gear and the transmission of one-level idle pulley forms; the sun gear that the output shaft of described rocking arm reduction box is planetary gears; the output shaft of planetary gears is connected by spline and square linking bond; cutting drum is sleeved on square linking bond, and the end face of cutting drum is provided with the bolt being fixed together with square linking bond.
The hard alloy steel that described pick-shaped cutter adopts Rockwell hardness to reach 60HRC processes.
Beneficial effect: the present invention takes full advantage of the pressure Zhang Xiaoying of coal petrography by cutting drum, is specially adapted to the exploitation in dirt band, hard dirt band coal seam.Cutting motor is directly laterally arranged in rocking arm housing, and motor is bolted in rocking arm housing.Cutting units machine driving comprises rocking arm reduction box and planetary gear reducing mechanism, has independently drive disk assembly of one's own.When hard dirt band coal seam winning machine cutting part is worked, cutting motor output shaft by transmission of power to rocking arm reduction box, after multistage roller gear and planet gear transmission speed reduction by transmission of power to cutting drum, cutting drum adopts square coupling sleeve to connect with planetary reducer output shaft, connect reliably convenient disassembly.On cutting drum, be furnished with high strength pick-shaped cutter, by the rotation of cylinder, realize the exploitation in coal seam.This structure adopts motor to drive, meet downhole anti-explosion requirement, cutting units overall structure is simply compact, adopt the special hard dirt band of brute force coal seam cutting drum, producing capacity is strong, can exploit the dirt band coal seam of coal petrography solid coefficient f<6, can meet the demand of the hard dirt band seam mining in down-hole, greatly improve the production efficiency in hard dirt band coal seam and the recovery rate of mining of coal resources.It is simple and compact for structure, is convenient to install, dismantle, and reliability is high, has practicality widely.
