Description

A kind of sugarcane docking device

Technical field

The utility model relates to a kind of sugarcane docking device, particularly relates to a kind of docking device that is used for sugarcane combine.

Background technology

Former, China's sugarcane harvesting overwhelming majority still relies on artificial hand-power to finish, but rely on and manually to finish not only very time and effort consuming, labour intensity is big, efficiency is low, and the harvesting cost of sugarcane is also higher, the harvesting means of some mechanizations therefore occurred.

Some basic demands to the sugarcane harvesting comprise: 1, sugarcane is broken apart by chopping, the crops for rotation that requirement is broken apart by chopping are 2-3cm overhead, and the breach of damage phenomenon can not be arranged, otherwise will influence the back several years harvest of sugarcane, 2, remove the tender bar of afterbody, requirement removes afterbody from the sugarcane soft tissue, if the afterbody excision is very few, it is low that the sugarcane portion that stays contains sugared composition more, influences sugared rate, can cause the loss in sugar refinery, if afterbody excision too much, will cause sugarcane grower's loss, 3, the stripping leaf, walnut hulling rate need reach 99%, sugared rate if the sugarcane top stripping totally can not reduce.

Present sugarcane combine both domestic and external according to the difference of the sugarcane form of gathering in the crops, is divided into the cutting type grain header and two types in the whole rod-type grain header that keeps whole bar sugarcane length of the short sugarcane bar that is cut to certain-length.The cutting type grain header is cut into sugarcane the segment of equal length in the harvesting process, therefore in machine, divest easily and the separation of sugarcane leaf, such grain header has solved easy blocking problem in the harvesting process, but the sugarcane of these class grain header results is because otch is more, need deliver to sugar refinery at short notice and press sugar, otherwise can cause going mouldy of sugarcane, the quality of influence sugar.The complex-terrain of the incompatible China of therefore this cutting type grain header, on a small scale, the needs of many units plantation.What therefore use at home is whole rod-type cane harvester mostly.Whole rod-type cane harvester; as China Patent No. is ZL200420064926.9 disclosed " multifunctional bagasse combine "; China Patent No. is ZL200520200252.5 disclosed " sugarcane combine "; the patent No. is the disclosed patents such as " sugarcane combines " of ZL200520200253.x; generally include dynamical system; running gear; operating system; preceding back-end crop mechanism; preceding gathering mechanism; break apart by chopping mechanism and leaf-peeling mechanism; also there is weak point in the leaf-peeling mechanism of these patents; these leaf-peeling mechanisms are the mode of arranging the leave stripping roller that occurs in pairs up and down on the transmission channel of sugarcane basically; leave stripping roller is made of roll shaft and the elastic bar that is arranged on the roll shaft usually; and in most these cane harvesters; the forward transmission of sugarcane in whole stripping leaf active section also only finished by leave stripping roller; even be provided with other conveying roller or inertia damping roller and so in individual other cane harvester; its structurally with the aspect, position be set also have deficiency, be difficult to obtain due effect.Leave stripping roller has stronger deformability by elastic bar thereon, and finishing of leaf of stripping must rely on the difference of transmission speed and leave stripping roller elastic bar linear velocity just can finish, the individual difference in size of adding sugarcane is bigger, therefore only depend on leave stripping roller to finish the transmission forward of sugarcane, the jiggly defective of transmission speed will appear, influence stripping leaf effect, the serious obstruction that also may cause sugarcane in the transmission channel.
