Abstract
The utility model discloses a kind of main on-off control mechanism, including handball, connecting rod, support shaft and tension spring, the handball is mounted on the upper end of connecting rod, the lower end connection support shaft middle part of connecting rod；One end of support shaft is equipped with ear pin, and the other end of support shaft is won in succession, and fixed block is equipped in the support shaft in ear pin and outside of winning in succession；The both ends of the tension spring are separately connected connection wire rod and lower connection wire rod, and the upper end of upper connection wire rod is hinged by upper connecting fork and axis pin and lower end of winning in succession, the lower connecting fork of lower end connection of lower connection wire rod.It is realized by tension spring and is tensioned by the connecting rod of interconnection, support shaft and the main clutch for clutch control of realization of winning in succession, simple in structure；It is connected by connecting fork, reduces the abrasion between component, increase service life；Integrated operation is convenient, improves work efficiency.
Description
Technical field
The utility model is related to a kind of main on-off control mechanisms, belong to agricultural machinery technological field.
Background technology
Main clutch is usually that grouped belt is arranged between driving wheel and driven wheel in the prior art, and grouped belt top is set
Set tensioning wheel, tensioning wheel connecting bracket, holder is mounted in rack, and tensioning spring one end is connect with tensioning pull rod, the other end and
Control crank connects, and can realize that tensioning wheel is combined with grouped belt by control crank ratchet mechanism, is connected driving wheel and follower
Between power transmission；After release control crank ratchet mechanism under return spring effect, tensioning wheel is detached with grouped belt, is cut
Disconnected power transmission between driving wheel and follower.Though this structure be easy to happen the power transmission between driving wheel and follower by
Cut-out, driving wheel be easy to cause the consumption of the energy so still in high speed rotation；When the separation of main follower is not thorough, it is easy
The abrasion of grouped belt is caused, to greatly reduce grouped belt service life；And grouped belt is elongated the adjusting pair of rear amount of tension
The mechanical aspects requested knowledge of operator of farm machinery is higher.
Invention content
The utility model aims to solve the problem that the above problem, provides a kind of main on-off control mechanism, simple in structure, and operation is just
Victory, it is not easy to wear.
Technical solution according to the present utility model, the main on-off control mechanism, including handball, connecting rod, support shaft and drawing
Spring, the handball are mounted on the upper end of connecting rod, the lower end connection support shaft middle part of connecting rod；One end of support shaft is equipped with ear pin,
The other end of support shaft is won in succession, and fixed block is equipped in the support shaft in ear pin and outside of winning in succession；The both ends of the tension spring
It is separately connected connection wire rod and lower connection wire rod, the upper end of upper connection wire rod passes through upper connecting fork and axis pin and lower end hinge of winning in succession
It connects, the lower connecting fork of lower end connection of lower connection wire rod.
Further, ear pin both sides are equipped with plain washer.
Further, one end that the bearing axis connection is won in succession is equipped with connecting plate, and described win in succession is mounted on using straight pin
On connecting plate.
Further, described to win in succession as arc.
Compared with prior art, the utility model has the advantage of：Pass through the connecting rod of interconnection, support shaft and reality of winning in succession
Now main clutch for clutch control is realized by tension spring and is tensioned, simple in structure；It is connected by connecting fork, reduces the abrasion between component, increased
Service life is added；Integrated operation is convenient, improves work efficiency.

The both sides of support shaft 7 limit.12 both ends of tension spring are separately connected connection wire rod 11 and lower connection wire rod 13, in upper connection wire rod 11
End is hinged by upper connecting fork 10 and axis pin and 9 lower ends of winning in succession, connecting fork 14 under lower 13 lower end of connection wire rod connection.Ear pin 8
Both sides are equipped with the plain washer 15 to shield.Win in succession 9 one end of support shaft 7 is equipped with connecting plate 17, and connecting plate 17 can be with
It is welded in support shaft 7,9 utilization straight pins 4 of winning in succession are mounted on connecting plate 17, and straight pin 4 is equipped with and is fitted and connected plate 17
Plain cushion 5, and lockked by split pin 6.It wins in succession and 9 could be provided as the other shapes such as arc or bending.
The utility model is realized by the connecting rod of interconnection, support shaft and the main clutch for clutch control of realization of winning in succession by tension spring
Tensioning, it is simple in structure；It is connected by connecting fork, reduces the abrasion between component, increase service life；Integrated operation is just
Victory improves work efficiency.
