Summary of the invention
The purpose of this utility model is the pay-off of a kind of axis in axis formula stalk scavenger of design, can make the conveying smoothness, stops stalk and twines the damage that causes the stalk scavenger, reduce the moving part of axle, reduce cost of manufacture, have simple in structure, result of use is good, long service life and advantage easy to use.For this reason, the utility model adopts between hinge dragon axle and impeller shaft and is provided with shaft device in the axle.Described axis in axis device by auger shaft, impeller shaft, be rotatably connected the cover and axis in axis hold the institute form, auger shaft and impeller shaft concentric arrange, the impeller shaft middle part is coupling by bearing and body, extra-organismal impeller shaft end connects impeller, the affixed blade assembly of impeller shaft end in the body and the cover that is rotatably connected, auger shaft one end hold with the cover that is rotatably connected by axis in axis and are coupling.Or described axis in axis device by auger shaft, impeller shaft, be rotatably connected the cover and axis in axis hold the institute form, auger shaft and impeller shaft concentric arrange, the impeller shaft middle part is coupling by bearing and body, extra-organismal impeller shaft end connects impeller, the affixed blade assembly of impeller shaft end in the body, auger shaft one end corresponding with blade assembly wheel is provided with the cover that is rotatably connected, and the impeller shaft end in the body holds with the cover that is rotatably connected by axis in axis and is coupling.Said structure has reached the purpose of this utility model.
Advantage of the present utility model makes screw-conveyer-shaft material conveying material center concentric corresponding with the stalk feeding mouth because auger shaft and impeller shaft concentric arrange, and not only can make the conveying smoothness, stops stalk and twines the damage that causes the stalk scavenger; And reduce the moving part 25% of axle, reduce cost of manufacture 30%.Have simple in structurely, result of use is good, long service life and advantage easy to use.

Specific embodiments
As shown in Figure 1, inventive point of the present utility model is shaft device partial structurtes in the axle, other position has structure as each component locations that: corn picker 1, tractor 2, stalk scavenger 3, the defeated moving axis 19 of two power, body 9, impeller 5, impeller shaft 6, blade 4, stalk feeding mouth 8, impeller assembly 13, air exhauster 12, spiral cut with scissors imperial sheet 11, hinge dragon axle 10, adjust nut 14, spring 15, spline gram sign indicating number 16, sprocket wheel 17 and chain 20, positioning sleeve 18 are formed for oneself, in background technology, describe, so do not state tired.
As shown in Figure 2, a kind of pay-off of axis in axis formula stalk scavenger mainly is made up of body, power output shaft, auger shaft, impeller shaft, sprocket wheel and chain, stalk feeding mouth and air exhauster.Between hinge dragon axle and impeller shaft, be provided with shaft device 7 in the axle.
As shown in Figure 3, described axis in axis device is held 23 and is formed by auger shaft, impeller shaft, be rotatably connected cover 21 and axis in axis.Auger shaft and impeller shaft concentric arrange.The impeller shaft middle part is coupling by bearing 22 and body.Extra-organismal impeller shaft end connects impeller, the affixed blade assembly of impeller shaft end in the body and the cover that is rotatably connected.Auger shaft one end holds with the cover that is rotatably connected by axis in axis and is coupling.Be the affixed blade assembly of the close bearing portion of impeller shaft end in the body, the affixed cover that is rotatably connected on the impeller shaft of blade assembly outer end.Be rotatably connected the cover in establish a middle (center) bearing.Establish the parabolic blade on the blade assembly.Auger shaft one end holds with the cover that is rotatably connected by axis in axis and is coupling.The described cover that is rotatably connected takes the shape of the letter U along the longitudinal cross-section, center.
Obviously, also can adopt: described axis in axis device by auger shaft, impeller shaft, be rotatably connected the cover and axis in axis hold the institute form, auger shaft and impeller shaft concentric arrange, the impeller shaft middle part is coupling by bearing and body, extra-organismal impeller shaft end connects impeller, the affixed blade assembly of impeller shaft end in the body, auger shaft one end corresponding with blade assembly wheel is provided with the cover that is rotatably connected, and the impeller shaft end in the body holds with the cover that is rotatably connected by axis in axis and is coupling.
