< b TranNum=" 99 ">described vertical open spiral combination axial threshing cylinder of putting, described importing blade is 2-4, the helical angle of described importing blade is 180 ° ~ 230 °.</b>
Beneficial effect:
< b TranNum=" 103 ">1. the importing blade of the utility model are covered with wearing layer with the finger sprig tooth surface that has radian, have improved its service life and have reduced maintenance cost.</b>
Its external form of finger sprig tooth of < b TranNum=" 105 ">the utility model has certain radian; Submissiveer minimizing impulsive force when guaranteeing to contact with seed with crop; Percentage of damage and brown rice rate have been reduced effectively; Refer to that the sprig tooth is connected with bolt with the cuved nail ratch and with its formation certain angle, the formation helix makes crop mobile more smooth and easy backward on circumference.</b>
The main shaft of < b TranNum=" 107 ">the utility model outside except that width of cloth dish be connected with the cuved nail ratch, refer to the sprig tooth, its complementary space be open; This kind structure makes the space that holds crop bigger; Seed is separated, be difficult for running grain, make the littler more difficult obstruction of resistance of cylinder.</b>
Refer on the width of cloth dish of < b TranNum=" 109 ">the utility model that the sprig tooth is bolt with the cuved nail ratch and is connected, when results are prone to broken crop, can symmetry dismantle a part, the strength that acts on the crop is reduced, to reduce the unnecessary loss that brings because of results.</b>
< b TranNum=" 111 ">the utility model structurally breaks away from traditional closed design of cutting streaming design and the outer splice tooth of most of producers cylinder fully, changes open threshing cylinder into.This product makes the space of drum threshing bigger, and seed and stalk be easy separation more, and resistance is littler, can blockage phenomenon.</b>
< b TranNum=" 113 ">the utility model has prolonged the service life of cylinder and has reduced maintenance cost, applies with wearing layer with the working surface that refers to the sprig tooth importing blade during fabrication, and the life-span of having improved this cylinder is more than one times.After tested, compare this harvest product efficient height with traditional axial-flow type drum under the equal conditions, can effectively reduce percentage of damage, the brown rice rate of grain, reduce power consumption, the peasant is increased income under the situation that does not increase cultivated area and input.</b>
