Description
Technical field
The present invention relates to the technical field that billets of cane is carried, refer in particular to a kind of for segmenting type sugar cane harvesterCollapsible scraper-type conveying arm.
Background technology
The sugarcane whether harvesting sugarcane machinery according to obtains results carries out segment processing, and to be divided into whole rod-type sweetSugarcane harvester and segmenting type sugar cane harvester.
Segmenting type sugar cane harvester results obtain billets of cane and generally need to be transported in time on field transport vehicle. ?Present stage, there are two kinds of modes that billets of cane is delivered on transport vehicle. A kind of is the billets of cane advanced person that results are obtainedRow Ji Dui, the then disposable field transport vehicle the inside of sending into. Another kind is gathering in the crops with scraper-type conveying armTo billets of cane send in real time in accompanying field transport vehicle. After first Ji Dui, carry the advantage of this mechanism to have:Simple and compact for structure, transfer position is accurate. But also there are these following shortcomings: when transhipment, need to stopCar, can not gather in the crops continuously, and efficiency is not high; In the harvest machinery in collection heap stage, owing to being loaded in gradually collectionThe billets of cane of heap device increases weight and increases, and causes energy consumption to increase and centre-of gravity shift; The height that can carry when transhipmentSpend limited, can only be supporting or need to sugarcane could be carried by other equipment with highly less field transport vehicleTo large-scale transport vehicle. Another kind be with scraper-type conveying arm results to billets of cane be transported to field transportCar the inside. The principal character of scraper-type conveying arm is that stock supporting plate is to fix, scraper plate billets of cane from stock supporting plateThereby on blow the object that reaches conveying off. The advantage of scraper-type conveying arm has: the billets of cane that results can be arrived andIn time, is transported to inside field transport vehicle, can not cause tare to increase because hoarding billets of cane; Carry billets of caneIn time, can be proceeded to gather in the crops, and efficiency is high; Billets of cane can be transported on relatively large transport vehicle, not needWant other instrument auxiliary. But the shortcoming of scraper-type conveying arm has, for the adaptability of different transport vehiclesPoor, throw position inaccurate, easily billets of cane is dished out outside sugarcane transport vehicle; Complete machine structure is not compact, spyNot in middle-size and small-size segmenting type combined harvester, if adopt scraper-type to carry real-time the billets of cane of resultsSend in accompanying field transport vehicle, in order to mate the overall height of field transport vehicle and to keep harvester and field transportThe spacing of car, the length of conveying arm just can not be too short. But meanwhile,, sugarcane conveying arm size is too large, again canHave influence on rodability and the property easy to store of harvesting sugarcane machinery, do not embody middle-size and small-size harvesting sugarcane machineryThe advantage of flexibility.
