Abstract

The utility model provides a guyed clutch. The clutch has simple structure and convenient operation, and is suitable for being used by matching with agricultural implements which rotate in low speed. The utility model comprises a stayguy, a stayguy bracket, an upright frame, a plectrum plate, a plectrum block, a driven shaft, a driven chain wheel, a drive shaft, a drive chain wheel, a spring and a spline housing, etc. The stayguy bracket is fixed on the upright frame; the two ends of the sleeve of the stayguy are respectively fixed on a handle and the stayguy bracket; the two ends of the core wire of the stayguy are respectively fixed on the handle and the plectrum plate; the plectrum plate is hinged to the upright frame; a thin shaft at one side of the spline housing is sleeved with the spring, and the spring is positioned between the spline housing and the plectrum block; the thin shaft is arranged inside the drive shaft and is in clearance fit with the drive shaft; the plectrum block is integrated with the driven shaft into a whole, and plectrum teeth on the plectrum plate are grasped on the plectrum block; teeth which are distributed along the circumference are arranged at the conjoint position between the driven shaft and the drive shaft; the driven shaft is provided with the driven chain wheel; the driven shaft is meshed with the drive shaft, and the drive shaft is provided with the drive chain wheel.

Description

Pulling clutch

Technical field

The utility model relates to the agricultural machinery clutch of a kind of agricultural machinery parts, particularly low speed transmission.

Background technology

At present, the finding clutch is very various, belongs to the clutch of high speed transmission mostly, be basically to form with gear or gear train structure, and all be to carry out clutch with control stick, it is also not too convenient to operate.Used clutch also all is to adopt similar structures aspect agricultural machinery.This clutch configuration complexity, cost height, the maintenance and repair inconvenience, and it is also not ideal to be used for general low speed transmission agricultural machinery.

Summary of the invention

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of pulling clutch.This clutch configuration is simple, easy to operate, is fit to the supporting use of agricultural tool with the low speed transmission.

The utility model is made up of backguy, guy wire support, stand, group plate, shifting block, driven shaft, driven sprocket, driving shaft, drive sprocket, spring and spline housing etc.; Guy wire support is fixed in the stand, and backguy overcoat two ends are separately fixed on handle and the guy wire support, and backguy heart yearn two ends are separately fixed at handle and dial on the plate, dial plate and are hinged in the stand; Be set with spring on the thin axle of spline housing one side, spring between spline housing and shifting block, thin axle be contained in the driving shaft and with the driving shaft matched in clearance, shifting block and driven shaft are one, the moving tooth on group plate is grabbed on shifting block; Driven shaft and driving shaft connecting place are circumferential tooth, and driven sprocket is housed on the driven shaft, and drive sprocket is equipped with in driven shaft and driving shaft engagement on the driving shaft.

The utility model adopts backguy, dials plate, spring and shifting block as critical piece, and the handle on the operating grip just can make driving shaft and driven shaft reach effective clutch easily.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 removes structural representation after the stand for Fig. 1;

Fig. 3 is that the A of Fig. 2 is to view.

Embodiment

Fig. 1, Fig. 2 and shown in Figure 3, the utility model is made up of backguy 2, guy wire support 3, stand 4, group plate 5, shifting block 11, driven shaft 6, driven sprocket 9, driving shaft 7, drive sprocket 8, spring 12 and spline housing 1 etc.Guy wire support 3 is fixed in the stand 4, and the used line of bicycle cable brake is adopted in backguy 2, and backguy 2 overcoat two ends are separately fixed on handle and the guy wire support 3, and backguy 2 heart yearn two ends are separately fixed at handle and dial on the plate 5, dial plate 5 and are hinged in the stand 4.Be set with spring 12 on the thin axle of spline housing 1 one sides, spring 12 is between spline housing 1 and shifting block 11, and shifting block 11 be an one with driven shaft 6, thin axle be contained in the driving shaft 7 and with driving shaft 7 matched in clearance, the moving tooth 10 on group plate 5 is grabbed on shifting block 11; Driven shaft 6 is circumferential tooth with driving shaft 7 connecting places, and driven sprocket 9 is housed on the driven shaft 6, and driven shaft 6 and driving shaft 7 engagements are equipped with drive sprocket 8 on the driving shaft 7.When the needs transferring power, unclamp handle, spring 12 stressed weakening, spring 12 elongations, shifting block 11 is away from spline housing 1 motion, and the driven shaft 6 that is connected as a single entity with shifting block 11 meshes with driving shaft 7, thereby reaches the effect of transferring power; When needs disconnect power, the handle of holding with a firm grip, backguy 2 is reclaimed and pulling is dialled plate 5 to the motion of compression spring 12 directions, and the moving tooth of dialling on the plate 5 10 is stirred shifting block 11 motions, forces driven shaft 6 to break away from driving shaft 7, thereby cuts off power.
