Description

The ensiling cutting machine tool carrier

Technical field

The utility model relates to a kind of farm implements, i.e. a kind of ensiling cutting machine tool carrier.

Background technology

The ensiling cutting machine is a kind of feed processing machine tool, can become feed stripped to crops stalk crushing.Existing ensiling cutting machine is mainly with the tractor-drawn operation, between advancing, finish stalk harvesting, pulverize, throw, the operation such as entrucking.The main working parts of ensiling cutting machine is cutting knife, and cutting knife is contained on the knife rest, and is furnished with blower fan, and the stalk that shreds directly is blown in the accompanying compartment.Because the cutting knife working resistance is large, thereby knife rest must have enough intensity.For this reason, existing knife rest all is to be processed from strand by foundry goods.Although casting strength is very high, very heavy, and can not weld, can only disposablely use, be difficult to maintenance in case damage, and knife rest is consumable accessory, so use cost is higher.In addition, the cutting knife that assembles can not be adjusted the position, and service behaviour is relatively poor.Mounting means and the structure of fan also are restricted, not only loading and unloading inconvenience, and need to expend larger energy.

Summary of the invention

The purpose of this utility model provides and a kind ofly can weld, be convenient to keep in repair, lightweight, cutter location is adjustable, fan power consumption is less ensiling cutting machine energization knife rest.

Above-mentioned purpose is realized by following technical scheme: develop a kind of ensiling cutting machine tool carrier, comprise rotating shaft and cutting knife, be characterized in: be equipped with fixed head and cutterhead above the said rotating shaft, fixed head is connected mutually with rotating shaft, link to each other by adjustable bolt between cutterhead and the fixed head, many tool rests are installed in front at cutterhead, and cutting knife is housed on the tool rest, and fan is equipped with in the back of cutterhead.

Said cutterhead is a rectangular steel plates, the centre has axis hole, along the uniform many group installing holes of diagonal, in the front of cutterhead, every group of installing hole installed a secondary tool rest, and tool rest is the angle steel shape and is made of base plate and side plate, perforate matches with the through hole of cutterhead on the base plate, have through hole on the side plate and match with the installing hole of cutting knife, the fan of cutterhead back is relative with the base plate of the tool rest of cutterhead front, and links to each other by same screw rod.

Said cutting knife is to be bent into the obtuse angle by rectangular steel plates to be become, and wherein one side is winning in succession of linking to each other with tool rest, and another side is blade.

Said fan is made of the multi-disc blade, and flanging and the cutterhead of root of blade join.

Said every group of installing hole all has three through holes, and an angle α is arranged between the circle center line connecting of three through holes and the diagonal of cutterhead, and the through hole center of circle that it is interior and cornerwise distance are 16-19mm.

Said cutterhead is circular steel plate.

The polygon steel plate of said cutterhead.

The beneficial effects of the utility model are: this knife rest can weld without foundry goods, is convenient to maintenance, and operating cost significantly reduces, and lightweight, and intensity is high, and is not fragile.Cutter location is adjustable, and cutting performance is good.Tool rest and cutting knife are consistent with the fan propeller direction, can increase wind-force by auxiliary blower, and the work energy consumption significantly reduces, and is expected to become the replacement type of existing product.

Embodiment

But the total design of the utility model is the cutting-off tool rest with the ensiling cutting machine changes the weldment structure into by unweldable casting structure.Around this design, introduce two kinds of embodiment:

The first embodiment: as shown in Figure 1, 2, this knife rest has the rotating shaft 1 of a horizontal, and rotating shaft 1 is supported by two cover bearings and linked to each other with shell, shell is because belonging to conventional components, its shape and knife rest adapt, and do not have drive 8 to engage with engine so draw an end of rotating shaft 1, can drive rotating shaft 1 and rotate.In conjunction with Fig. 3,4 as seen, the parts made of series winding two block plates in the rotating shaft 1, the front is to be contained in cutterhead 2 in the rotating shaft 1 by axis hole 17, the back is the fixed head 6 that is fixed in the rotating shaft 1.Link to each other by adjusting bolt 9 between fixed head 6 and the cutterhead 2, the front and back position of cutterhead 2 can be by adjusting bolt 9 adjustment.In the front of cutterhead 2, along the uniform fourth officer tool rest 3 of diagonal, in conjunction with Fig. 5,6 as seen, and tool rest 3 shapes such as angle steel, a side is base plate 11, the side plate 12 of opposite side.Base plate 11 links to each other with the installing hole 10 of cutterhead 2 by through hole, and side plate 12 links to each other with cutting knife 4 by through hole.In conjunction with Fig. 7,8 as seen, cutting knife 4 is the obtuse angle angle steel that formed by steel plate bending, and a side links to each other with the side plate 12 of tool rest 3 by through hole, and side is blade 14 in addition.In the back of cutterhead 2, by through hole fan 5 is housed, fan 5 also is the angle steel shape, and the flanging 16 of a side links to each other with cutterhead 2 by through hole, and the blade 15 of opposite side is perpendicular with 2 of cutterheads.In conjunction with Figure 11 as seen, fan 5 splits cutterhead 2 both sides with tool rest 3, and relatively installs, and tool rest 3 and blade 14 also have the effect of fan propeller 15 when cutting operation.

In conjunction with Figure 12 as seen, cutterhead 2 is rectangular steel plates, the centre has axis hole 17, along the uniform four groups of installing holes 10 of diagonal, every group of installing hole 10 has three through holes, an angle α is arranged between the diagonal of the circle center line connecting of three through holes and cutterhead 2, and the through hole center of circle that it is interior and cornerwise distance are 16-19mm, and the through hole center of circle of its outermost and diagonal approach.Like this, can make tool rest 3 and cutting knife 4 have the angle that is suitable for cutting.

Experiment showed, that this knife rest compares with the foundry goods knife rest, weight significantly alleviates, and manufacturing cost also significantly reduces, and particularly all parts all can weld, and is convenient to maintenance, occurs damaging easily recovering, and has significantly prolonged the service life of consumable accessory, has reduced operating cost.In addition, because adjustable before and after the position of cutterhead 2, the gap that equals cutting knife and stalk feeding mouth is adjustable, the raising that brings thus cutting performance.

The second embodiment: as shown in figure 13, this cutterhead 2 also be one with the steel plate of installing hole 10 and axis hole 17, different from last embodiment is, steel plate is rounded, the shape that cutterhead 2 is described can be diversified, can be polygon or ellipse etc., all belong to the technical scheme that is equal to.
