Abstract

The utility model relates to agriculture machinery, in particular to improvement of cutting tool in combine harvester. The cutting tool is braid cutting structure of haircut pushing shearing device. A dynamic knife row is moved reciprocally and is corresponded with a fixed knife row to shear bar and stem in transverse direction. Head section of the fixed knife forms a partial grass joint in spindle tip shape with edge protecting device. Length of the fixed knife is longer than the length of the dynamic knife, which improves shear break rate of bar and stem.

Description

The secondary cut cutter of full feeding rice wheat combine

Technical field:

The utility model relates to agricultural machinery, particularly to the improvement of cutting tool in the combine.

Background technology:

Existing combine, by technological progress, existing secondary cut function, but effect still has much room for improvement.During such as the secondary cut cane, if meet bigger rice bunch, in the time of then can not entering between moving, the stationary knife fully, cane is often pushed over and can not be cut off.

Summary of the invention:

The purpose of this utility model is the cutting tool that the full feeding rice wheat combine is provided the high secondary cut function of a kind of cane cutting rate.

The hair-cutting structure of the similar hair clipper device of the utility model, moving knife is arranged relative stationary knife horizontal row yearning complex shears and is cut motion, it is characterized in that the head of stationary knife makes the grain separating head of the spur shape with guard, stationary knife length can improve the percent shear of cane greater than moving knife length.

Among above-mentioned stationary knife row or the moving knife row between every adjacent two blades distance be 50～80mm.

The utility model is owing to make the grain separating head that protects the sword device with the stationary knife top, stationary knife is longer than moving knife, if when running into thicker root bunch, stationary knife spur shape grain separating head inserts separately in the middle of bunch root during operation in harvesting, moving knife is subsequently cut off cane, can not produce down stem and not cut phenomenon.

Description of drawings:

Fig. 1 is a stationary knife unit vertical view during stationary knife is arranged among Fig. 1 for the moving blade row vertical view that makes up surely, Fig. 2, and Fig. 3 is Fig. 2 upward view, and Fig. 4 is an A-A sectional view among Fig. 2, and Fig. 5 is a moving knife unit vertical view during moving knife is arranged among Fig. 1.

Embodiment:

With reference to Fig. 1～Fig. 5, the stationary knife unit is made " Jiong " shape by foot piece 1-4 with two stationary knifes, and a plurality of unit L=75mm equidistantly are installed on the cutter beam, each stationary knife 1 both sides is blade 1-1, point of a knife constitutes the fusiformis grain separating head 1-2 with guard 1-3, and foot piece 1-4 has the plane, to constitute moving knife row's slide rail.Moving knife 2 is installed on the cutter beams 3 with stationary knife 1 corresponding interval, makes formation shear surface in plane on moving knife lower plane and the stationary knife, and cutter beams 3 constitutes the slide bar that cooperates with stationary knife row slide rail simultaneously, and its termination is controlled by swing mechanism, drives reciprocating motion about moving knife row.Stationary knife length is greater than moving knife length, and stationary knife point in service can contact stem bunch branch standing grain in advance, and moving knife is sheared the cane of its both sides then, is not pushed over and does not cut phenomenon thereby can not produce cane.

Claims

1, a kind of secondary cut cutter of full feeding rice wheat combine, moving knife is arranged relative stationary knife horizontal row yearning complex shears and is cut motion, the head that it is characterized in that stationary knife (1) is made the have guard grain separating head (1-2) of spur shape of (1-3), and stationary knife (1) length is greater than moving knife (2) length.

2, combine according to claim 1 is characterized in that among stationary knife row or the moving knife row that distance is 50～80mm between every adjacent two blades.
