Abstract

The invention relates to a double-roll grass chopping cutter of a grass chopper. The double-roll grass chopping cutter comprises parallel cutter rolls, wherein a feeding gap is arranged between the two cutter rolls; cutter strips and material guiding strips are spirally arranged on the outer walls of the cutter rolls at intervals; cutter grooves and cutting teeth distributed at intervals are arranged on the cutter strips; material guiding grooves are formed in the material guiding strips; the cutter strips between the two opposite cutter rolls are distributed in a staggered manner; the outer ends of the cutter strips are located on the outer sides of the cutter grooves and form material cutting gaps with the cutter grooves. According to the double-roll grass chopping cutter, the chopping and guiding of the grass materials are realized by combining the spirally arranged cutter strips with the material guiding strips, so that the double-roll grass chopping cutter is simple and convenient to operate, high in grass chopping efficiency and good in effect.

Description

Double roller grass-smashing reamers of grass chopper

Technical field

The present invention relates to technical field of agricultural machinery, particularly relate to grass chopper.

Background technology

Grass chopper is for forages such as guillotine cutting Caulis et Folium Oryzae, millet straws, for nursing and the fertile fertilizer in farmland of domestic animal.Broken Grass machine is widely used to common farmers' family, and it substitutes artificial broken grass, reduction work degree, improve broken Grass efficiency.

Grass chopper of the prior art, the double roller cutting grass knife of general employing, roll shaft is provided with polylith blade, logical Cross relative blade to carry out rolling cutting.Existing pair of roller cutting grass knife only possesses and has broken grass function, needs during rolling cut External force to be utilized constantly feeding between blade, troublesome poeration, efficiency is low, there is also feeding and hindered the most at that time The potential safety hazard of hands.

Summary of the invention

The applicant is for shortcoming present in above-mentioned prior art, it is provided that a kind of grass efficiency rational in infrastructure, broken Double roller grass-smashing reamers of the grass chopper high, use is safe.

The technical solution adopted in the present invention is as follows:

Double roller grass-smashing reamers of a kind of grass chopper, including parallel cutting roller, with feed space between two cutting rollers Gap, the alternate screw arrangement of outer wall of cutting roller have cutting knife bar and guide bar, on cutting knife bar with cutting knife groove and Spaced apart cutting, with deflector chute on guide bar；

Between two relative cutting rollers, cutting knife bar is staggeredly arranged, and the outer end of cutting knife bar is positioned at the outside of cutting knife groove also Blank gap is maintained with it.

Beneficial effects of the present invention is as follows:

The cutting knife bar that the present invention uses spiral to arrange combines with guide bar and realizes the chopping to forage and derivation, Its grass efficiency easy and simple to handle, broken is high, effective.

Fig. 1 is the front view of the present invention.

Fig. 2 is the top view of Fig. 1.

Wherein: 1, cutting roller；2, cutting knife bar；21, cutting knife groove；22, cutting；3, guide bar；31、 Deflector chute.

Detailed description of the invention

Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.

As shown in Figure 1 and Figure 2, double roller grass-smashing reamers of the grass chopper of the present embodiment, including parallel cutting roller 1, between two cutting rollers 1 with charging gap, the alternate screw arrangement of outer wall of cutting roller 1 have cutting knife bar 2 And guide bar 3, with cutting knife groove 21 and spaced apart cutting 22 on cutting knife bar 2, cutting 22 is by cutting Cutter groove 21 is separated into the two cutter block portions being separated by, and its chaffcutter, particle are effective；

With deflector chute 31 on guide bar 3, deflector chute 31 is beneficial to derive particle；

The relative cutting knife bar 2 between two cutting rollers 1 is staggeredly arranged, and is formed cutting structure, cutting knife bar 2 Outer end is positioned at the outside of cutting knife groove 21 and maintains blank gap with it.

Two cutting rollers 1 of the present invention relatively rotate, and owing to cutting knife bar 2 is arranged for spiral with guide bar 3, cut During material, forage is involved in inside, it is not necessary to forage applies extraneous thrust, and it is easy and simple to handle；Forage after chopping Deriving between cutting knife bar 2 and guide bar 3, part particle is derived from deflector chute 31.

Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is joined See claim, within protection scope of the present invention, any type of amendment can be made.
