Abstract
The utility model discloses a coal winning machine clutch provided with a novel end cover, and belongs to the technical field of mining machines. The coal winning machine clutch comprises a handle, a motor shaft, a hollow-shaft motor, a push rod, the semicircular end cover, and an outer extending flange positioned on a handle clamping block far away from an axis line end of the push rod, wherein, a clamping groove matched with the flange is formed on the end cover; a positioning block of the push rod on a handle passes through a corresponding designed hole on the semicircular end cover; and the handle clamping block of the handle passes through the clamping groove on the end cover. The coal winning machine clutch has the benefits that as the end cover of the clutch is semicircular, the contact surface is increased; and the handle of the clutch cannot be pushed inwards when a cutting part is shutdown, so that the clutch is more convenient and has better safety performance in the operation and use process.
Description
Technical field
The utility model relates to a kind of coal winning machine clutch, relates in particular to a kind of coal winning machine clutch that has novel end cap, belongs to the mining machinery technical field.
Background technique
Being shaped as of traditional flitting clutch end cap is fan-shaped; when the needs cutting portion is shut down; when manipulating the very loaded down with trivial details because end cap of operation be one fan-shaped, when handgrip misses fan-shaped locating face, handgrip is moved to locating face; again handgrip is rotated to an angle; fixture block also and then rotates to an angle and has left the end cap draw-in groove, the cutting portion clutch just be in from state, clutch handle can push away inward; so just cause misoperation easily, be easy to cause security incident.
Summary of the invention
At above-mentioned existing technical problem, the utility model provides a kind of coal winning machine clutch that has novel end cap, and it is more accurate to operate, use more convenient, Security is better.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of coal winning machine clutch that has novel end cap, comprise handgrip, motor shaft, empty shaft motor and push rod, also comprise semicircle end cap, be positioned at away from the outer extension flange on the line end handgrip fixture block of push rod axle center, the draw-in groove that matches with flange on the end cap, the positioning block of handgrip upper push-rod pass corresponding design hole on the semicircle end cap, and the handgrip fixture block of handgrip passes the draw-in groove on the end cap.
Further, motor shaft is to the perpendicular distance of the end cap length greater than the motor shaft spline.
Further, handle is formed in one with fixture block or detachable fixedly connected any.
The beneficial effects of the utility model are: because the clutch end cap is semicircle, surface of contact increases, and when cutting portion was shut down, clutch handle can not push away inward, and operation is more accurate, more convenient in manipulating process like this, Safety performance is better.

Among the figure: 1, semicircle end cap, 2, handgrip, 3, motor shaft, 4, gear, 5, strut, 6, empty shaft motor, 7, push rod, 8, draw-in groove, 9, flange, 10, the design hole, 11, spline, 12, positioning block.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of coal winning machine clutch that has novel end cap, comprise handgrip 2, motor shaft 3, empty shaft motor 6 and push rod 7, also comprise semicircle end cap 1, be positioned at away from the outer extension flange 9 on the push rod 7 axle center line end handgrip fixture blocks, the draw-in groove 8 that matches with flange 9 on the end cap 1, the positioning block 12 of handgrip 2 upper push-rods pass corresponding design hole 10 on the semicircle end cap 1, and the handgrip fixture block of handgrip 2 passes the draw-in groove 8 on the end cap.Handle 2 is formed in one with fixture block or detachable fixedly connected any.Motor shaft is to the perpendicular distance of the end cap length greater than motor shaft spline 11.
As shown in Figure 3 and Figure 4, the semicircle end cap clutch device of the utility model coal winning machine, in the time of the winning machine cutting part proper functioning, the fixture block of handgrip 2 is in end cap 1 draw-in groove, and handgrip 2 is designed to asymmetrical, can freely rotate in semicircle draw-in groove 8.
As shown in Figure 1; when needing cutting portion to shut down; just pull out handgrip 1; just motor shaft 3 has been pulled out; be not less than the length of spline 11 by the control handgrip distance of pulling out, just can allow spline 11 and gear 4 break away from fully, even motor is turned over like this; gear 4 can not change yet, and has so just realized clutch function.
