The technical scheme includes that a motor in a machine seat frame is connected with a planetary transmission mechanism via a fixed shaft transmission mechanism, an output end of the planetary transmission mechanism is connected with a transitional fixed shaft transmission mechanism, and a gear of an output end of the transitional fixed shaft transmission mechanism is connected with a drum spindle located on a cantilever frame of a machine body. The cantilever type cutting device is applicable to various types of low seam mining machinery.
Description
Technical field:
The utility model relates to cutting machine, the machinery of particularly a kind of cutting rod or cutting drum slotting.
Background technology:
Existing low seam mining machinery, its cutting means adopts cantilever structure usually, its principal arm frame vertically is arranged in adopts sky side transporter top, and cantilever shalving is lying in the transporter top in ramp plate superjacent air space output transmission, bears power by helix drum and finishes coal breakage and coaling; Three grades of drivings of such cutting means are all adopted than the big retarding ratio, the driven gear size of its afterbody transmission is big, reduce planted agent's amount of cylinder and the coal space excessively between transporter/cantilever, when cutting motor power increases, driven gear is bigger, problem is more outstanding, need labor cleaning's float coal, production efficiency and safety all obviously descend, said structure is also too complicated simultaneously, this dealer is proposed the scheme that the two-stage dead axle transmission adds not the level Gear Planet Transmission, its final gear and level Gear Planet Transmission size is all not bigger, in the middle of work plane and two ends will have a strong impact on and cross the coal space between planted agent's amount of cylinder and the transporter cantilever.
The utility model content:
Technical problem to be solved in the utility model is, a kind of improved low seam mining machinery cantilevered cutting means is provided, and it can improve the coal mining efficient of low seam mining machinery, and can guarantee coal mining activity safety.
The technical scheme in the invention for solving the above technical problem is:
On the body mounting of low seam mining machinery cantilevered cutting means motor is installed, this motor drives through transmission mechanism and is connected with drum spindle, this drum spindle is provided with the helical form barrel, be characterized in: the motor in the body mounting drives the input that is connected with the epicyclic transmission mechanism with big speed ratio that is positioned at the body mounting through dead axle transmission mechanism, the output of described epicyclic transmission mechanism drives and is connected with the transition dead axle transmission mechanism that is positioned at body principal arm frame, and the gear of output end driving of described transition dead axle transmission mechanism is connected with the drum spindle of the cylinder that is positioned at the body cantilever shalving.Power train big retarding of the present utility model is than on the transmission mechanism that concentrates in the body mounting, and the speed ratio of final stage transmission mechanism is less in the principal arm frame.
The utility model adopts above-mentioned transmission distribution mode, not only gear of output end is little, corresponding cantilever shalving outside dimension is little, cause the blade height of effectively coalingging of cylinder to increase, can extend forming auxiliary blade, cutting means in the middle of coal-face and the planted agent of two (frame head and tail) measure increases, and can improve the cut moment of torsion, thereby solve fundamentally that existing cutting means production efficiency is low, poor reliability, labour intensity greatly, production safety problems such as do not guarantee.
Description of drawings:
Fig. 1 is the utility model low seam mining machinery cantilevered cutting means schematic diagram.
Fig. 2 is that the utility model is in the work plane front elevational schematic.
Fig. 3 the utlity model has bigger planted agent to measure schematic diagram.
The specific embodiment:
With reference to Fig. 1, low seam mining machinery cantilevered cutting means includes motor 1, dead axle transmission mechanism 2, epicyclic transmission mechanism 3, body 4, transition dead axle transmission mechanism 5 and cylinder 6; Motor 1 is installed on the mounting 41 of body 4; drive on the shaft extension of motor 1 and be connected with a torque axis 11; has the effect that reduces the power train twisting vibration; also has overload protection function simultaneously; torque axis 11 drives and is connected with dead axle transmission mechanism 2, and the speed reducing ratio that drives the dead axle transmission mechanism that is connected in motor 1 is not less than 2.
Dead axle transmission mechanism 2, Fig. 1 is shown a roller gear deceleration transmission, and in order to guarantee the utlity model has gear of output end 51 and less cantilever shalving 43 sizes than minor diameter, the gearratio of dead axle transmission mechanism 2 should be bigger, usually should be greater than 3, in the hope of the rationalization of power train.
Epicyclic transmission mechanism 3, as shown in Figure 1, the one end connects dead axle transmission mechanism 2, the other end connects transition dead axle transmission mechanism 5, the utility model adopts and lay the epicyclic transmission mechanism 3 with big speed ratio in body 4 mounting 41, be to reach the key technology measure that reduces gear of output end 51 and cantilever shalving 43 size purposes, the existing employing drives the scheme that connects epicyclic transmission mechanism on drum spindle 62, just can't reach the above-mentioned effect that reduces the key position size.
Transition dead axle transmission mechanism 5, be with the transmission of power of epicyclic transmission mechanism 3 transition driving member in the cutting means power train to cylinder 6, this mechanism includes one group of travelling gear, wherein the big young pathbreaker of gear of output end 51 diameters directly influences the size of cantilever shalving 43, just influence the key element of cutting means allomeric function, under the condition that satisfies transfer torque intensity, the diameter of gear of output end 51 should make every effort to reduce, at this, the utility model is equipped with under the prerequisite of big retarding than epicyclic transmission mechanism 3 before adopting power train, the gearratio of transition dead axle transmission mechanism 5 can be selected smaller value, should be not more than 1.2 usually.
Fig. 2 represents that the utility model is when work plane two (frame head and tail), with conveyer 70, drift section 71, center, tunnel 72, the relation of force piece 73, under the cylinder 6 diameter certain conditions of cutting means, has bigger cylinder planted agent amount, this cylinder planted agent amount hachure (hatching) part as shown in Figure 3, mainly be because gear of output end 51 sizes are less, cantilever shalving 43 sizes are also less simultaneously, when the same roller diameter, cylinder blade height of the present utility model and planted agent's amount all increase, thereby can well the floor be cut, coal is taken on, avoid existing structure too small, cause 6 pairs of base plates of cylinder not cut fully because of the cylinder planted agent measures, the labour intensity that exists in the time of need manually entering the rib cleaning is big, uneasy congruent problem; The utility model is because speed ratio is bigger, under identical power conditions, effective cut moment of torsion of its cylinder 6 outputs can increase, consequently, whole coal-winning machine has stronger adaptive capacity in the coal seam to complex geological condition, unit reliability strengthens greatly, has solved girdle high production rate restriction problem.
