Description

Two roller grass-smashing reamers of grass chopper

Technical field

The utility model relates to technical field of agricultural machinery, particularly relates to grass chopper.

Background technology

Grass chopper is for forages such as guillotine cutting straw, millet straws, for the nursing of livestock and the fertile fertilizer in farmland.Grass chopper has been widely used in common farmers' family, and it substitutes artificial broken grass, reduces work degree, improves broken careless efficiency.

Grass chopper of the prior art, the two roller cutting grass knife of general employing, roll shaft being provided with polylith blade, being undertaken rolling to cutting by relative blade.Existing pair of roller cutting grass knife only has broken careless function, and need to utilize external force during rolling cut constantly to feeding between blade, troublesome poeration, efficiency is low, also there is the potential safety hazard that hand was not hindered in feeding at that time.

Utility model content

The applicant, for the shortcoming existed in above-mentioned prior art, provides that a kind of careless efficiency rational in infrastructure, broken is high, two roller grass-smashing reamers of the grass chopper of use safety.

The technical scheme that the utility model adopts is as follows:

A kind of two roller grass-smashing reamers of grass chopper, comprise parallel cutting roller, with charging gap between two cutting rollers, the alternate screw arrangement of outer wall of cutting roller have cutting knife bar and guide bar, with cutting knife groove and spaced apart cutting on cutting knife bar, 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 and maintains blank gap with it.

The beneficial effects of the utility model are as follows:

The cutting knife bar that the utility model adopts spiral to arrange combines with guide bar and realizes chopping to forage and derivation, and its easy and simple to handle, broken careless efficiency is high, effective.

Accompanying drawing explanation

Fig. 1 is front view of the present utility model.

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

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

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1 and Figure 2, two roller grass-smashing reamers of the grass chopper of the present embodiment, comprise parallel cutting roller 1, with charging gap between two cutting rollers 1, 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 separated into the two cutter block portions be separated by by cutting knife groove 21, its chaffcutter, particle are effective;

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

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

Two cutting rollers 1 of the present utility model relatively rotate, and because cutting knife bar 2 and guide bar 3 are arranged for spiral, be involved in toward in by forage during blank, without the need to applying extraneous thrust to forage, it is easy and simple to handle; Forage after chopping is derived between cutting knife bar 2 and guide bar 3, and part particle is derived from deflector chute 31.

More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
