Abstract

The utility model relates to an agricultural machine, particularly a grain combine harvester. A gating concave plate and a feeding inlet of the utility model are provided with turnover plate teeth, wherein, the turnover plate teeth can be a plurality of rows, each row can be a plurality of teeth which are staggered. The utility model can carry out combing for grains. Thus, the problem that late tillage grains are difficult to thresh is solved. After the utility model adopts a rod-tooth-type axial flow drum with small diameter, the utility model can still keep constant line speed. Then the angular speed is increased, and thus the wrapping angle of the grating concave plate can reach 240 DEG which is greater than the original 180 DEG. The utility model has the advantages of good grain threshing and separating effects, compact structure, simple structure, wide application, higher threshing thorough for various rice, wheat, etc., and low cost.

Description

Small-sized intensive self-propelled axial flow grain combine

The utility model relates to a kind of farm machinery, particularly a kind of grain combine.

At present, existing self-propelled axial flow grain combine, higher to threshing performances such as hybrid rice, wheat, but its complex structure, parts are many and big, cause that the machine volume is big, cost is high.And for late japonica rice, then threshing performance obviously reduces, and effect is extremely undesirable.

The purpose of this utility model will overcome above-mentioned defective exactly, designs a kind of to equal height of various paddy and wheat threshing performances and volume is little, parts are few combine.

The technical solution of the utility model:

Its major technique feature is at grid concave plate feeding mouth place turning plate tooth to be set, the tooth-like axial-flow type drum transverse cross-section parallel of its flank of tooth and bar, and crown points to the axle center of the tooth-like axial-flow type drum of bar.

Advantage of the present utility model and effect are to adapt to wide, and to threshing performance height such as hybrid rice, late japonica rice, wheat, effect is obvious, and it is simple in structure, compact, saved many mechanisms and parts, volume is little, in light weight, cost is also low, especially is fit to operations such as fritter field, terraced fields.

The structural representation of grid concave plate and turning plate tooth among Fig. 2-Fig. 1.

Embodiment:

As shown in Figure 1, the foremost is a cam-action reel 1, and is hinged with header 2, and header 2 is made of reciprocating cutterbar 3, auger 4, carrier chain 5, is installed on the chassis 6; The tooth-like axial-flow type drum 7 of bar also is installed on the chassis 6, and this example adopts the tooth-like axial-flow type drum 7 of diameter 450mm bar, and its exterior rim is provided with grid concave plate 8, is installed on the chassis 6, and its cornerite is 240 degree; And for example shown in Figure 2, at the feeding mouth place of grid concave plate 8 turning plate tooth 9 is set, and is fixed on the grid concave plate 8, the transverse cross-section parallel of the tooth-like axial-flow type drum 7 of the flank of tooth of turning plate tooth 9 and bar, crown points to the axle center of cylinder 7; In this example, being provided with turning plate tooth 9, one rows of two rows is three, and a row is four, staggers each other; Below cylinder 7 and the rear portion, have and remove auger 10, centrifugal fan 11, reciprocating type sieve 12, rethresher 13, elevator 14 etc. by throwing and constitute cleaning plant; Chassis 6 comprises fuselage, wallboard.

During work, the cam-action reel 1 of front turns round counterclockwise, cereal is comprised that cane dials to header 2, by 3 cuttings of the reciprocating cutterbar on it, transport to the feeding mouth place of the tooth-like axial-flow type drum 7 of bar again by auger 4, carrier chain 5, cylinder 7 turns round counterclockwise, cereal is comprised that cane grabs into threshing, in threshing course, the cylinder 7 of rotation is crumpled grain with fixing grid concave plate 8 and is comprised cane, and grain is taken off; Because that the tooth-like axial-flow type drum 7 of this routine king-rod adopts is diameter 450mm, with respect to diameter bigger for, under the constant situation of on-line velocity, angular speed is bigger, the centrifugal force that seed is subjected to is bigger, thereby the cornerite of grid concave plate 8 just can be done greatlyyer in this example, be 240 degree, so its threshing, separating effect is good; Especially 9 pairs of cereal of turning plate tooth of staggering each other of two rows on the feeding mouth place of grid concave plate 8, grid concave plate 8 curry, the cereal that difficulty is taken off, and as late japonica rice etc., effect is better; Cane is discharged from from the side by the centrifugal force of cylinder 7; the seed impurity is removed auger 10 throwings through throwing and is raised; clean by centrifugal fan 11, reciprocating type sieve 12,, do not clean clean assorted surplus and residual fringe and after rethresher 13 takes off again, clean again and get final product by elevator 14 input tankers.Thus, the utility model has saved helping the original text device, help complex mechanisms such as original text wheel on the combine in the past.

Claims

1, small-sized intensive self-propelled axial flow grain combine is characterized in that at grid concave plate feeding mouth place turning plate tooth being set, the tooth-like axial-flow type drum transverse cross-section parallel of the flank of tooth and bar, and crown points to the axle center of the tooth-like axial-flow type drum of bar.

2, small-sized intensive self-propelled axial flow grain combine according to claim 1 is characterized in that turning plate tooth is provided with two rows, every row several, stagger mutually.
