Background technique
Large at present, main in medium-sized tractor, the application of secondary independent manipulation clutch configuration is comparatively extensive, and the PTO clutch of most of tractor is all normal engagement type, whether normal engagement type PTO clutch no matter work by power output, PTO clutch friction plate is always in running order, often be combined power train part always in operating condition with PTO clutch friction plate, therefore certainly will cause the power loss that a part is unnecessary, PTO clutch friction plate is normal convolution simultaneously, unavoidably because of factors such as engine starts, the friction plate slippage wearing and tearing that the impact that is hit causes, cause the abnormal in early stage wearing and tearing of friction plate.
Model utility content
The purpose of this utility model is to provide a kind of normal separated type PTO clutch operating device, take to solve that to adopt the PTO clutch of existing use be normal convolution, has power loss and the clutch friction plate flimsy technical problem that is hit.
The utility model is to realize like this, a kind of normal separated type PTO clutch operating device, comprise supporting base, on described supporting base, rotate a coupling shaft is installed, described coupling shaft is fixedly connected with an operating handle, on the described supporting base of described coupling shaft top, rotate a back shaft is installed, described back shaft is fixedly connected with the second swing arm, one end of described the second swing arm is connected with the operation flexible axle of PTO clutch separation or combination described in assisted control, the other end connects described coupling shaft by linkage mechanism, described linkage mechanism comprises arc pull bar and the first swing arm, one end of described arc pull bar is hinged with corresponding described the second swing arm, the other end and described the first swing arm are hinged, described the first swing arm is fixedly connected with described coupling shaft,
Described PTO clutch is when separated original state, described arc pull bar is positioned at described coupling shaft and described back shaft all away from the same side of described operation flexible axle, depress described operating handle and make described PTO clutch when bonding state, described arc pull bar lower end tie point is positioned at the side top of the axial connecting line elongation line of described arc pull bar upper end tie point and described coupling shaft.
As improving further, the distance between described the first swing arm two ends is the first brachium, and the distance between described the second swing arm two ends is the second brachium, and described the first brachium is less than described the second brachium.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because normal separated type PTO clutch initial position is in separated state, solved traditional normal convolution PTO clutch, no matter power is exported whether combination, the parts of being combined with friction plate are always in operating condition, while causing power loss and engine start, the problem of impact friction sheet, simple to operate, safe, reduce energy waste, the working life of greatly having improved clutch.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 and Fig. 2 are common, a kind of normal separated type PTO clutch operating device, comprise supporting base 1, on supporting base 1, rotate a coupling shaft 2 is installed, coupling shaft 2 is fixedly connected with an operating handle 10, on the supporting base 1 of coupling shaft 2 tops, rotate a back shaft 4 is installed, back shaft 4 is fixedly connected with the second swing arm 5, one end of the second swing arm 5 is connected with the operation flexible axle 7 of assisted control PTO clutch separation or combination, the other end connects coupling shaft 2 by linkage mechanism, linkage mechanism comprises arc pull bar 6 and the first swing arm 3, one end of arc pull bar 6 is hinged with the second corresponding swing arm 5, the other end and the first swing arm 3 are hinged, the first swing arm 3 is fixedly connected with coupling shaft 2, coupling shaft 2 and back shaft 4 can be rotatably installed on supporting base or by other rotating manners and all can by bearing.
PTO clutch is when separated original state, arc pull bar 6 is positioned at coupling shaft 2 and back shaft 4 all away from the same side of operation flexible axle 7, depressing operating handle 10 makes PTO clutch when bonding state, arc pull bar 6 lower end tie points are positioned at the side top of the axial connecting line elongation line of arc pull bar 6 upper end tie points and coupling shaft 2, the position of energy Reliable guarantee mechanical caging operating handle 10.Above-mentioned normal separated type PTO clutch can be realized under clutch normality in normal off state, now clutch friction plate is not worked, remain static with the power train part of the normal combination of friction plate, simultaneously also can not cause the percussion to friction plate during engine start.
Distance between the first swing arm 3 two ends is that the distance between the first brachium 30, the second swing arm 5 two ends is that the second brachium 50, the first brachiums 30 are less than the second brachium 50.The parameters such as stroke of the length of the first brachium 30 and the second brachium 50, the arc length of above-mentioned arc pull bar 6, radius and arc angle and the first brachium 30, the second brachium 50 and arc pull bar 6, operational requirements according to actual needs calculates.
The first swing arm 3 is connected by connecting pin 8 with the joint of operation flexible axle 7 with joint and second swing arm 5 of arc pull bar 6 respectively with joint, second swing arm 5 of arc pull bar 6, and on connecting pin 8 respectively correspondence be provided with cotter pin 9.Adopt connecting pin 8 and cotter pin 9 Placements, simple in structure, be easy to realize connection, be convenient to installation and maintenance and dismounting.
While using operation, original state PTO clutch is in separated state, and now friction plate is separated with engine flywheel, in the time of need to be in conjunction with clutch, as shown in Figure 2, press operating handle 10, operating handle 10 actions drive coupling shaft 2 rotations, coupling shaft 2 rotarily drives connected the first swing arm 3 and swings, after swinging, the first swing arm 3 drives one end action of arc pull bar 6, now the other end of arc pull bar 6 pulls one end of the second swing arm 5 to move downward, meanwhile the other end of the second swing arm 5 moves upward, pull operation flexible axle 7 motions, along with constantly depressing of operating handle 10, when being pressed onto the two-end-point of arc pull bar 6 and the axle center of coupling shaft 2 always and being in same straight line or above-mentioned side top position, arrive the dead center position of mechanism, position that now can mechanical locked operating handle 10, operation flexible axle 7 is combined the friction plate of clutch and the flywheel of motor with the parts action in dynamic clutch therewith, realize the combination of clutch, whole operating process is simple, PTO clutch is normal separate type, greatly improved the Security in using process, reduce the loss of energy consumption, extend the working life of clutch.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
