Description

The operating mechanism of sower clutch

The utility model relates to a kind of operating mechanism of sower clutch.

Sower is many to be driven by medium and small tractor, and the driving wheel of tractor is passed to sprocket wheel with power through clutch, and this sprocket wheel passes to the seeds box seeding through driving-chain; When being seeded into the field two ends, turn round to return and continue sowing, at this moment should stop sowing, in order to avoid the waste seed.I disclose a kind of sower power formula clutch in Chinese patent ZL97200396.7, can carry out clutch reposefully, sow equably.But I find that the hoisting velocity of the lifter that it handles clutch is slower in development thereafter, the clutch separation time is longer, influence the seed waste, and sowing row ridge is unclear.Prior art has improvement, perfect necessity.

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of operating mechanism of improved sower clutch is provided, and in being contained in, the manual clutch that connects is handled easily, and clutch speed is fast, and seed is saved in sowing, makes the edge of a field two ends ridge clear.

The purpose of this utility model is achieved in that a kind of operating mechanism of sower clutch, this clutch comprises and is loaded on coaxial moved end face fluted disc and quiet contrate gear, the end-side teeth of this two dynamic and static fluted disc is realized the normally closed type rotational engagement by spring top clamping, the end-side teeth external stairs of this two sound fluted disc forms an annular groove; It is characterized in that:

Described operating mechanism is by separating plate, catch bar, push-pull arm, control crank composition; Separating the plate top is the flat plate that slotted hole/elongated slot is arranged, this slotted hole/elongated slot is sleeved in the annular groove, there is sloping shape inclined-plane the both sides, lower end of this flat plate and overcomes spring force for the separation plate when annular groove moves radially and will move, the end-side teeth of quiet fluted disc separates and realization rotation interruption, this separates plate lower end connecting push-and-pull rod, the hinged push-pull arm in this pull bar lower end, the hinged rotating shaft of this push-pull arm, this rotating shaft is by being contained in the sleeve supporting that is fixed in holder, affixed manipulating handgrip is held in rotating shaft in addition, this holder is contained in the frame of the agricultural four-wheel tractor of tractor seeder, on the relevant position of pedal, this manipulating handgrip is over against position that driver's arm can reach

The utility model has following actively useful effect:

This mechanism advantage is that the driver is easy to operate, speed is fast, and 2-3 can sow or stop sowing second, makes two ends the edge of a field ridge clear, has saved seed.

Now in conjunction with the accompanying drawings:

Fig. 1 is the structural representation of the utility model one embodiment;
