A kind of group standing grain structure for grain header
Technical field
The present invention relates to a kind of group standing grain structure for grain header.
Background technology
Grain header refers to the straw cutting down the crops such as paddy and wheat, and is laid in the cereal harvesting machinery in field.Horizontal ceding of Taiwan grain header and two kinds, standing header grain header is had according to the type of the ceding of Taiwan.The most volume of existing grain header is comparatively large, operation inconvenience, very flexible, and manufacturing cost is higher.
Summary of the invention
The object of this invention is to provide a kind of group standing grain structure for grain header.
To achieve these goals, by the following technical solutions: a kind of group standing grain structure for grain header, is characterized in that: the described standing grain structure of dialling for grain header comprises a pair symmetrically arranged dialing-grain unit; Be provided with sprocket wheel bottom described dialing-grain unit, in the middle of sprocket wheel, rice-pulling shaft be installed, rice-pulling shaft is provided with successively two and dials standing grain dish; Described two sides of dialling near rice-pulling shaft on standing grain dishes are provided with push rod, two dial standing grain dish near outer place also each uniform intervals be provided with a circle rice-pulling tooth, this rice-pulling tooth and dial standing grain dish connecting axle on be provided with torsion spring.
Described push rod has the cambered surface consistent with dialling standing grain dish outer near the side of dialling standing grain dish outer.
Described push rod accounts for 1/4th of whole circumference near the cambered surface dialling standing grain dish outer.
Rice-pulling tooth on described each group of standing grain dish is four.
The principle of the invention is simple, by dialling the work of rice-pulling tooth on standing grain dish, can be good at group standing grain work in harvesting process, seedlings of cereal crops grain header front end can cut off are sent in threshing system successively, it is easy and simple to handle, and operating efficiency is high, has very strong practical value.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figures 1 to 5, a kind of group standing grain structure for grain header, comprises a pair symmetrically arranged dialing-grain unit 1; Be provided with sprocket wheel 5 bottom described dialing-grain unit 1, in the middle of sprocket wheel 5, rice-pulling shaft 6 be installed, rice-pulling shaft 6 is provided with successively two and dials standing grain dish 3; Described two sides of dialling near rice-pulling shaft 6 on standing grain dishes 3 are provided with push rod 4, two dial standing grain dish 3 near outer place also each uniform intervals be provided with a circle rice-pulling tooth 2, this rice-pulling tooth 2 and dial standing grain dish 3 connecting axle 201 on be provided with torsion spring 202.
Described push rod 4 has the cambered surface consistent with dialling standing grain dish 3 outer near the side of dialling standing grain dish 3 outer.
Described push rod 4 accounts for 1/4th of whole circumference near the cambered surface dialling standing grain dish 3 outer.
Rice-pulling tooth 2 on described each group of standing grain dish 3 is four.
During work, driven by motor sprocket wheel operates, and sprocket wheel drives rice-pulling shaft to rotate, and dials standing grain dish along with rice-pulling shaft synchronous axial system, dials the rice-pulling tooth also run-in synchronism thereupon on standing grain dish.When rice-pulling tooth runs to push rod position, rice-pulling tooth is withstood by push rod, forces rice-pulling tooth to rotate around connecting axle, and the tip of rice-pulling tooth front end is stretched out, and plays the effect of dialling standing grain.Rice-pulling tooth can move along the cambered surface of push rod always, and after leaving push rod cambered surface, rice-pulling tooth can automatic drawing back under the torsion spring effect on connecting axle, and make it no longer protruding, what complete epicycle dials standing grain task.Along with the continuous running of motor, the rice-pulling tooth dialled on standing grain dish can circulate in turn and stretch out and regain, thus reaches group standing grain object, the seedlings of cereal crops of harvesting can be sent in the threshing system of rear end endlessly.
The principle of the invention is simple, by dialling the work of rice-pulling tooth on standing grain dish, can be good at group standing grain work in harvesting process, seedlings of cereal crops grain header front end can cut off are sent in threshing system successively, it is easy and simple to handle, and operating efficiency is high, has very strong practical value.
