Abstract
The invention relates to a high efficiency short wall coal cutter that includes cut arm, lifting oil cylinder and sliding base frame. The cut arm is made up of cut motor, cut roller and cut reducer. The invention designs the cut arm to portrait swinging, and the cut roller to circular truncated cone. It size of the machine would sharply decrease and the entire structure is small and flexible. It has the advantages of simple structure, light weight, low cost and high efficiency.
Description
Technical field
The present invention relates to a kind of coal excavation apparatus, the short-wall coal-winning machine of, safety efficient especially for the shortwall coal seam, mechanical mining belongs to technical field of mining equipment.
Background technology
In the prior art, the structure of common short-wall coal-winning machine and conventional longwall coal-winning machine is similar, and majority is single cylinder, fuselage is shorter, and rocking arm is positioned at waist to be arranged by the working face of coal seam direction, but teeter or rotation, to realize the purpose of index drum position, coal mining machine roller is a column type.The short-wall coal-winning machine fuselage length of said structure is the shortest also more than 3 meters, this physical dimension is not suitable for exploiting the working face of coal seam needs of 20 meters following length, and because complex structure, moving component is many, makes plant maintenance difficulty, cost cost height, poor reliability.In addition, the purpose that feed is mined in order to realize the Shortwall mining high-efficient homework, to reach not starting shooting nest, requirement is shorter the coal-winning machine fuselage designs, and in order to pursue short fuselage designs, then must improve the structure of existing short-wall coal-winning machine.
Summary of the invention
The present invention is used to overcome the defective of prior art and the high efficient short-wall coal-winning machine that a kind of fuselage length is little, adopt the longitudinal oscillation cutting arm is provided.
The alleged problem of the present invention is that following technical scheme solves:
A kind of high efficient short-wall coal-winning machine, be installed on the track of bottom transporter, comprise cutting arm, hoist cylinder and slippage underframe in the formation, described cutting arm is made up of cutting motor, cutting reducer, cutting-cylinder, wherein cutting motor drives cutting reducer, cutting reducer drives cutting-cylinder and rotates, its special feature is: described cutting arm is articulated on the slippage underframe, the hinged slippage underframe of the hinged cutting arm middle part other end of described hoist cylinder one end, hoist cylinder drives the cutting arm longitudinal oscillation.
Above-mentioned high efficient short-wall coal-winning machine, described cutting-cylinder are truncated cone-shaped, and its diameter dimension is increased progressively to afterbody by the cutting-cylinder end.
The defective that the present invention is directed to existing short-wall coal-winning machine rocking arm teeter is improved, the coal-winning machine cutting arm is designed to longitudinal oscillation, and cutting-cylinder is designed to truncated cone-shaped, can reduce to below 1.5 meters through above-mentioned improvement rear body size, overall structure is small and exquisite flexibly, head, the drive end unit that can climb up the bottom transporter cut the work plane two ends, and can realize the nest of not starting shooting, directly feed in the tunnel.The present invention is simple in structure, in light weight, use is flexible, high efficiency, cost only is 1/3 of traditional short-wall coal-winning machine, this design can be satisfied the exploitation needs of shortwall or ultrashort wall working face of coal seam fully, be particularly useful for steep-inclined thick coal seam horizontal mechanical caving coal mining, and the exploitation of shortwall corner, colliery coal.
Description of drawings
Fig. 1 is the structural representation of the present invention and bottom transporter;
Fig. 2 is that the A of high efficient short-wall coal-winning machine among Fig. 1 is to revolved view.
The label of each parts is expressed as follows in the accompanying drawing: 1. bottom transporter; 2. cutting-cylinder, 3. cutting reducer; 4. cutting motor; 5. hoist cylinder; 6. slippage underframe; 7. traction motor; 8. high efficient short-wall coal-winning machine; 9. haulage chain.
The specific embodiment
The present invention is a kind of short-wall coal-winning machine of longitudinal oscillation cutting arm, described longitudinal oscillation is meant that cutting arm swings up and down perpendicular to the rib direction, this coal mining machine roller is heightened the direction difference, structure and common teeter short-wall coal-winning machine are also inequality, reach the shortest purpose of coal-winning machine fuselage after the improvement, realized efficient, the safe fully-mechanized mining in shortwall coal seam.As seen from Figure 1, the present invention is installed on the transporter 1 of bottom, its slippage underframe 6 rides on the track of special-purpose transporter, can slide back and forth along track, slide traction power and derive from traction motor 7, traction motor drives haulage chain 9 by driven wheel, and haulage chain is connected with the slippage underframe, and the oil-feed direction that changes motor can realize that cutting part moves back and forth.
Key improvements of the present invention is the swaying direction of cutting arm, referring to Fig. 1, Fig. 2, cutting arm is made up of cutting motor 4, cutting-cylinder 2, cutting reducer 3, wherein cutting motor drives cutting reducer, cutting reducer drives cutting-cylinder and rotates, cutting arm one end is articulated on the slippage underframe, the hinged cutting arm of hoist cylinder 5 one ends middle part, the hinged slippage underframe of the other end drive the cutting arm longitudinal oscillation, to adjust the high and low position of cutting-cylinder when hoist cylinder moves.Cutting-cylinder 2 is designed to truncated cone-shaped, and its reducing size is increased progressively to afterbody by the cutting-cylinder end.The design of cutting-cylinder band tapering can guarantee the smooth of top, cut coal seam, base plate, and the physical dimension of cutting-cylinder can be determined according to the coal seam of cut different-thickness.Can realize by increasing cutting-cylinder diameter and circulation cut number of times for big mining height.
Design of the present invention can make fuselage foreshorten to below 1.5 meters, small and exquisite, the flexible movements of physical dimension, the head of transporter, tail are to cut the work plane two ends bottom climbing up, and can realize the nest of not starting shooting, directly feed in the tunnel, cutting-cylinder respectively along coal-face top and twice of bottom or twice above cut finish and once move frame.
Claims (2)
1. high efficient short-wall coal-winning machine, be installed on the track of bottom transporter, comprise cutting arm, hoist cylinder and slippage underframe in the formation, described cutting arm is made up of cutting motor, cutting reducer, cutting-cylinder, wherein cutting motor drives cutting reducer, cutting reducer drives cutting-cylinder and rotates, it is characterized in that: described cutting arm is articulated on the slippage underframe (6), the hinged slippage underframe of the hinged cutting arm middle part other end of described hoist cylinder (5) one ends, hoist cylinder drives the cutting arm longitudinal oscillation.
2. a kind of high efficient short-wall coal-winning machine according to claim 1 is characterized in that: described cutting-cylinder (2) is a truncated cone-shaped, and its diameter dimension is increased progressively to afterbody by the cutting-cylinder end.
