Therefore, the transmission and operation efficiency is improved. Meanwhile, the blockage and belt-clamping accidents are avoided and the threshing device is better in separation effect.
Description
Technical field
The utility model relates to thresher, relates in particular to a kind of horizontal double axial drum type sheller unit.
Background technology
Existing thresher mainly is made up of bearing support, cover plate, threshing cylinder and threshing concave plate.By the feeding of crop and the way of output of forage, thresher mainly is divided into axial-flow type and cuts two kinds of streamings.The sheller unit that is used for combine at present mainly contains the mixed type sheller unit that the sheller unit of vertical single, double axial threshing cylinder and axial-flow type drum and cut flow roller are used in combination
The longitudinal axial flow threshing cylinder use separately or two cylinders vertically (vertically) be used in combination side by side, formed vertical single, double axial threshing device.Be provided with the spiral grass guide board in the pairing cover plate of longitudinal axial flow threshing cylinder.During threshing, crop axially feeds to an end from drum shaft, by threshing cylinder and the spiral grass guide board guiding straw outlet to the axial other end for the helical movement, has taken off the stalk of grain and has been exported by straw outlet.Grain on the crop separates with the stem stalk through the acting in conjunction of threshing cylinder and threshing concave plate, falls in the corn catcher of cylinder below.The major defect of axial threshing cylinder is, special screw auger feeding unit is set, and consumption of power is big, and the stem stalk easily stops up in cylinder.Because longitudinal size is big, can not increase the Rethresher structure more simultaneously, like this, for the difficult threshing of the crop of high humidity, the difficult separation, it is unclear to cause final grain to separate, and breakage rate is big.
The mixed type sheller unit mostly is the combining form of preposition cut flow roller and rearmounted axial-flow type drum.Flow-cut threshing cylinder places an end of axial threshing cylinder.Crop is tangentially imported by the feeding mouth of flow-cut threshing cylinder, and tangentially exports the feeding mouth of axial-flow type drum one end to through the effect of this threshing cylinder, again through the guiding of this longitudinal axial flow cylinder and the inboard grass guide board of cover plate, moves to the straw outlet of the axial other end.In this process, through the effect of threshing cylinder and disengaging notch board, the grain on it separates with the stem stalk crop in cylinder, and its stalk is exported by straw outlet.The defective of the horizontal twin-roll of this kind is that preposition cut flow roller threshing course is short, separating effect is bad and percentage of damage is big, particularly the crop of high humidity is carried serious (it is serious to carry grain secretly in the isolated stalk) secretly because separating effect is bad, and the rate that causes damage is big.The side that the grass outlet of while back is partial to cylinder, as this sheller unit is placed on the combine, the grass of discharge (stalk) is piled up in Tanaka's one side, can not be sprinkling upon Tanaka equably, influences straw-returning.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, crop is difficult for stopping up when proposing a kind of threshing, good separating effect is not carried secretly substantially and is gone out grass and can evenly shed a kind of horizontal double axial drum type sheller unit in Tanaka, and this sheller unit is realized by following technical proposals:
Described sheller unit, comprise the two axial flow threshing cylinder, the bearing support of supporting axial threshing cylinder, place the cover plate of threshing cylinder upside, place the threshing concave plate of threshing cylinder downside, place the grass guide board of surveying in the cover plate, feeding mouth and straw outlet, wherein said two axial flow threshing cylinder is radially arranged side by side, feeding mouth and straw outlet are separately positioned on two described axial threshing cylinders radially on the tangential position of a side, be positioned at two threshing concave plates of two described axial threshing cylinder downsides, the axial both ends of its adjacent side are provided with breach respectively, survey in the two described cover plates to be respectively equipped with the grass guide board that rotary orientation is opposite and be symmetrically distributed.
The further design of described sheller unit is that described feeding mouth or straw outlet inboard are equipped with shear flow thresher.
The further design of described sheller unit is that described shear flow thresher comprises flow-cut threshing cylinder and places the threshing concave plate of flow-cut threshing cylinder downside.
The further design of described sheller unit is that the straw outlet outside of described axial threshing cylinder is provided with straw shaker.
The further design of described sheller unit is that described threshing concave plate below is provided with the auger conveying mechanism.
The further design of described sheller unit is that described breach is a rectangle.
The further design of described sheller unit is that axial described breach with the end is connected by a plate on described two threshing concave plates.
The further design of described sheller unit is that described threshing cylinder is tooth-like or spiketooth type or a rasp bar formula of bar.
The utility model passes through radially (horizontal) arrangement side by side of two axial flow threshing cylinder, and feeding mouth and grass outlet are separately positioned on the tangential direction of two axial flow threshing cylinder cylinder, crop tangentially feeds in threshing, can save special feeding unit, make simple in structure and saved the power that corresponding feeding structure is consumed.Outlet is arranged on the axial centre position of axial threshing cylinder rear side, has taken off the stalk (grass) of grain and has tangentially dished out, and can shed equably Tanaka, helps straw-returning.Simultaneously, the reverse acting spiral of grass guide board being arranged to symmetry distributes, and makes the input crop divide two directions to move vertically, and even load improves the efficiency of transmission of crop when threshing, is difficult for stopping up.Crop is when threshing, and is for the helical movement along threshing cylinder, and the seed on it is subjected to the probability height of threshing cylinder and threshing concave plate effect, makes the threshing performance height, is difficult for carrying secretly stalk and grain good separating effect.In addition, the two axial flow threshing cylinder is radially horizontal side by side, makes the sheller unit compact conformation, so that have living space at feeding mouth or grass outlet all stream threshers is set again, and threshing performance is further improved.
