The model utility content
For the prior art above shortcomings, the purpose of this utility model just is to provide a kind of driving mechanism clutch assembly of rotary tillage tractor-ploughing cutter assembly, and is simple in structure, and good stability is easy to safeguard, and with low cost.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of driving mechanism clutch assembly of rotary tillage tractor-ploughing cutter assembly, comprise car body, be arranged on driving wheel and follower and the drivign belt of winding on driving wheel and follower on car body, it is characterized in that: described drivign belt and driving wheel and follower are slidably matched; Be provided with an Idle wheel below drivign belt, described Idle wheel is connected with an end of a clutch lever, and described clutch lever is arranged on car body by lever dolly, and the middle part of clutch lever and lever dolly are rotationally connected; This clutch lever is away from the upwards bending of an end of Idle wheel, and this end is positioned at the top, joint of clutch lever and lever dolly all the time; Also be provided with a clutch handle on car body, described clutch handle is arranged on car body by handle bracket, and clutch handle and handle bracket are rotationally connected; This clutch handle is connected with the end of clutch lever away from Idle wheel by a pull bar, can drive the clutch lever rotation by rotating clutch handle.
Further, be provided with an extension spring above pole, the lower end of described extension spring is connected with the end of clutch lever near Idle wheel, and the upper end is positioned at the top of drivign belt and is connected with car body by spring bracket; By extension spring, Idle wheel is upwards drawn, can guarantee that in the course of the work drivign belt is in tensioning state, thereby make the operation of ploughing the cutter assembly more stable.
Further, described clutch handle is inverted L shape, and vertical section of described pull bar and handle is connected; Be more convenient for operating.
Compared with prior art, the utility model has the advantage of: simple in structure, realize clutch by the matching relationship that changes between drivign belt and driving wheel and follower, not fragile, good stability is safeguarded and changes conveniently, and with low cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-driving wheel, 2-follower, 3-drivign belt, 4-Idle wheel, 5-clutch lever, 6-lever dolly, 7-clutch handle, 8-handle bracket, 9-pull bar, 10-extension spring, 11-spring bracket.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: referring to Fig. 1, a kind of driving mechanism clutch assembly of rotary tillage tractor-ploughing cutter assembly comprises car body, is arranged on driving wheel 1 and follower 2 and the drivign belt 3 of winding on driving wheel 1 and follower 2 on car body.Described drivign belt 3 is slidably matched with driving wheel 1 and follower 2; Namely under the effect without external force, belt is in relaxed state, and this moment, driving wheel 1 can't drive follower 2.Be provided with an Idle wheel 4 below drivign belt 3, described Idle wheel 4 is connected with an end of a clutch lever 5, and when specifically making, this Idle wheel 4 is connected with clutch lever 5 by pole.Described clutch lever 5 is arranged on car body by lever dolly 6, and the middle part of clutch lever 5 and lever dolly 6 are rotationally connected.This clutch lever 5 is away from the upwards bending of an end of Idle wheel 4, and this end is positioned at the top, joint of clutch lever 5 and lever dolly 6 all the time.
Also be provided with a clutch handle 7 on car body, this clutch handle 7 is inverted L shape, and vertical section of described pull bar 9 and handle is connected.Described clutch handle 7 is arranged on car body by handle bracket 8, and clutch handle 7 is rotationally connected with handle bracket 8; This handle bracket 8 is positioned at the front portion of car body, so that operation.During concrete enforcement, described handle bracket 8 has a horizontally disposed mounting plate, be provided with the support device that is made of two risers and bearing pin on this mounting plate, clutch handle 7 is connected with bearing pin and can carries out front and back around bearing pin and rotate (take car body as reference, namely rotating to the front and rear direction of car body).
Described clutch handle 7 is connected with the end of clutch lever 5 away from Idle wheel 4 by a pull bar 9, can drive clutch lever 5 rotations by rotating clutch handle 7.During concrete enforcement, pull bar 9 is connected with clutch handle 7 by a connecting rod, and pull bar 9 is positioned at a side of handle bracket 8, and pull bar 9 can not hindered by support like this, and operation can be carried out smoothly.
Be provided with an extension spring 10 above pole, the lower end of described extension spring 10 is connected with the end of clutch lever 5 near Idle wheel 4, and the upper end is positioned at the top of drivign belt 3 and is connected with car body by spring bracket 11.By extension spring 10, Idle wheel 4 is upwards drawn, can guarantee that in the course of the work drivign belt 3 is in tensioning state, thereby make the operation of ploughing the cutter assembly more stable.
When clutch handle rotates forward, driving clutch lever by pull bar down moves the Idle wheel on clutch lever, make drivign belt be in relaxed state, driving wheel can't be with follower like this, simultaneously pull bar and clutch handle connecting place are positioned at the below of horizontal plane at the rotating shaft place of clutch handle, at this moment clutch handle contacts with support, and can not be rotated further by the spacing clutch handle that makes of support, thereby produces self-locking under the effect of spring force; When clutch handle rotates backward, Idle wheel moves up under the drive of clutch lever, cross the horizontal plane at rotating shaft place of clutch handle when pull bar and clutch handle connecting place after, under the effect of extension spring, Idle wheel moves up rapidly and with the feed belt tensioning, thereby stablizes, clutch safely and effectively.
Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
