Abstract
The utility model relates to an improvement of a tangential-flow drum for threshing of crops, in particular to an improved tangential-flow drum, which comprises a drum shaft, a secondary disc drum and a drum body; wherein, a threshing truss plate seat is fixed and arranged on the outer surface of the drum body in a manner of uniformity and staggering. A rectangular threshing truss plate made of macromolecular material, provided with a circular arc groove arranged at the top end of the threshing truss plate, is fixed on a fixing panel of the threshing truss plate seat by a fixing bolt. As the threshing truss plate of the utility model is made of the macromolecule material of favorable elasticity and the circular arc groove is arranged at the top end, the utility model has the characteristics of high toughness compared with the truss plate made of rigid material, improves the grasping ability for the material under the preconditions of guaranteeing the threshing performance, and reduces the striking strength based on improving the striking frequency for the material, thereby reducing the crushing rate of the grain and the striking damage rate of the stalk, and reducing the load of cleaning and separating.
Description
Technical field: the utility model relates to the improvement of a kind of grain threshing with cut flow roller, is meant a kind of improved cut flow roller especially.
Background technology: at present, domestic with Xinjiang-2 type self-propelled cut the axial flow grain combine be representative the 2-4kg/s feed quantity cut the axial flow combine, because its cut flow roller adopts traditional tooth plate cylinder, in operation process, receive to pass a bridge transmit come do not take off material after, take off and the mode of hitting is carried out threshing and conveying with comb, the problem of its existence is ineffective to the extracting of material, and the strike effect is too strong; Wherein grasping ineffective performance is material has slippage in grasping course of conveying possibility, thereby causes the outlet logistics alluvial of passing a bridge; Cause the percentage of damage of seed to exceed standard and hit too strong result, cause that cleaning thing in the cleaning room increases, and skewness.
Summary of the invention: the purpose of this utility model provides a kind of strong to the material extracting, and the moderate improved cut flow roller of strike effect.
The purpose of this utility model is achieved in that a kind of improved cut flow roller, comprise drum shaft, width of cloth dish drum and stack shell, wherein evenly interlocking on the outer surface of stack shell is set with threshing tooth plate seat, is fixed with the threshing tooth plate that the rectangular top made from macromolecular material has arc groove by set bolt on the fixed panel of threshing tooth plate seat.
Because the threshing tooth plate on the utility model is to be made by the macromolecular material with favorable elasticity, and be provided with arc groove on its top, its with make tooth plate with rigid material and compare characteristics with high tenacity, so it can be under the prerequisite of guaranteeing the threshing performance, raising is to the extracting ability of material, and on improving, reduce the intensity of hitting to the basis of material striking frequency, thereby reduced the rate that smashes of the percentage of damage and the cane of seed, alleviated the load of cleaning, improve the unobstructed property of material, reached the effect of flexible threshing.
Description of drawings: Fig. 1 is a front view of the present utility model
Fig. 2 is the right view of Fig. 1
Fig. 3 is the local structure for amplifying schematic diagram of A portion among Fig. 2
Specific embodiments: the utility model will be further described below in conjunction with drawings and Examples, a kind of improved cut flow roller, comprise drum shaft 4, width of cloth dish drum 3 and stack shell 5, wherein evenly interlocking on the outer surface of stack shell 5 is set with threshing tooth plate seat 1, is fixed with the threshing tooth plate 8 that rectangular top has arc groove 7 by set bolt 6 on the fixed panel 2 of threshing tooth plate seat 1.
The effect of the arc groove 7 on threshing tooth plate 8 tops is the grasp forces that improve material; And the threshing tooth plate made from macromolecular material 8 is owing to have high tenacity, thus its strike intensity under the situation of high speed rotating to material weaken, thereby can reduce the rate that smashes of the percentage of damage and the cane of seed effectively.
The macromolecular material of making threshing tooth plate 8 can be casting mold polyurethane high molecule material or modification casting nylon; Show that through test the shore hardness of threshing tooth plate 8 is 70-80 when spending, its action effect is better.
For further fixing threshing tooth plate 8, prevent that it is subjected to displacement on threshing tooth plate seat 1, have the detent that matches with fixed panel 2 shapes on the threshing tooth plate seat 1 at the back side of threshing tooth plate 8.
The utility model in use, enter the moment of drum chamber's mouth when material, grasped and hit by the threshing tooth plate on the utility model of high speed rotating 8, because threshing tooth plate 8 itself has high tenacity, and its top has arc groove 7, therefore, it not only has very strong extracting effect, and have a weak effect of hitting of high frequency, so it can be under the prerequisite that does not reduce the threshing performance, reduce to the damage ratio of seed with to the effect that smashes of cane.
