Description

Straw millstone

The utility model relates to a kind of straw millstone of straw cutting apparatus, more particularly, relates to and is used for the straight knife type straw millstone that straw cutting apparatus is finished crops straw and the pulverizing of root stubble.

China is a large agricultural country, and the tradition of intensive cultivation is always arranged, and behind crop harvesting, the processing of stalk and root stubble is a ubiquitous problem, and making in recent years, straw cutting apparatus obtains more and more general application.Crushed stalk is gone back the field on the spot, can increase the soil organic matter, and culture fertility has been subjected to peasant's welcome.But existing straw cutting apparatus is the L type owing to pulverize cutter, can not go deep in the soil layer of below ground, thus can only handle the above stalk in the face of land, and the root stubble can not be pulverized, and brings very burden can for the farming in later stage, and very big to the cultivating quality influence.In addition, the blade of straw cutting apparatus is generally 2-8 centimetre apart from ground, just can not pulverize for the crops straw of lodging, and it is better thing top layer crushing effect to occur shedding, and lower floor is embedded with the problem of long stalk, influences the straw-returning effect.

In order to overcome the above-mentioned shortcoming of prior art, the purpose of this utility model provides a kind of straight knife type reducing mechanism that can once finish crops straw pulverizing and the pulverizing of root stubble, so that eliminate the root stubble, improves the quality of farming.

For achieving the above object, straw millstone of the present utility model comprises: turning cylinder and Disintegrating knife, be fixed with manyly on the wherein said turning cylinder to supporting base, and described each upper end to supporting base is equipped with the Disintegrating knife of rotating a plurality of straight types.

And the upper end of described each supporting base is provided with a through hole that blade shaft is installed, and in described rotating shaft, string has a plurality of Disintegrating knifes rotationally, has sleeve pipe between the described Disintegrating knife.

And described Disintegrating knife is rectangle, and has the inclined plane along long limit, and its two ends respectively have a through hole, also can have a through hole at the one end.

If this reducing mechanism, be installed in the straw cutting apparatus, as shown in Figure 1, then the transmission of power that is provided by supporting unit is to gearbox 3, be sent to the turning cylinder of this reducing mechanism again through V belt, this turning cylinder drives Disintegrating knife 5 high speed rotating, through pulverizing the effect of cutter 5 and ledger-plate 4, with crushed stalk, Disintegrating knife 5 buries 1-3 centimetre at work simultaneously, the root stubble is pulverized, like this in the farming in later stage, just big Tu Fa (piece) can not occur, thereby cultivating quality is significantly improved because of the existence of root stubble.

Fig. 1 is that straw millstone of the present utility model is installed on the general structure schematic diagram on the straw cutting apparatus;

Fig. 2 is the structural representation of straw millstone of the present utility model;

Fig. 3 is the structural representation of straw millstone of the present utility model;

Fig. 4 a and 4b are respectively the plane and the profiles of a kind of Disintegrating knife of this straw millstone;

Fig. 5 a and 5b are respectively the plane and the profiles of the another kind of Disintegrating knife of this straw millstone.

Below, in conjunction with the accompanying drawings, describe most preferred embodiment of the present utility model in detail.

At first, illustrate that straw millstone of the present utility model is installed on the general structure on the straw cutting apparatus, as shown in Figure 1, as existing straw cutting apparatus, it comprises: casing 1, facility bar 2, gearbox 3, be installed on the ledger-plate 4 in the casing 1 and the turning cylinder 6 of reducing mechanism along the direction perpendicular to drawing, on this turning cylinder 6 Disintegrating knife 5 etc. be installed.In addition, be provided with walking roller 7 in casing 1 back with the contact position, ground.

The transmission of power that is provided by supporting unit is delivered to the turning cylinder 6 of straw millstone again to the gearbox 3 of straw cutting apparatus through V belt, this turning cylinder 6 drives blades 5 high speed rotating, through the shear action of Disintegrating knife 5 with ledger-plate 4, with crushed stalk.

Secondly, the structure of the reducing mechanism of straw cutting apparatus of the present utility model is described, as shown in Figure 2, this reducing mechanism comprises: turning cylinder 6, a pair of supporting

base

8a and 8b, blade shaft 11 and a plurality of Disintegrating

knife

5a, 5b, 5c and 5d etc.

Each end of a pair of supporting

base

8a and 8b is fixed in the top of this turning cylinder 6, and the other end of this supporting

base

8a and 8b respectively is provided with a through hole (not drawing among the figure) that can supply to penetrate blade shaft 11.Can think that this blade shaft 11 resembles spike, the one end has the bigger ailhead of diameter, and the other end is provided with split pin 9, so that be fixed on the supporting base.In these rotating shaft 11 tops, between two supporting

base

8a and 8b, string has Disintegrating

knife

5a, 5b, 5c and 5d etc. rotationally, and has sleeve pipe 10 between these blades 5a, 5b, 5c and the 5d, makes the interval of each blade keep certain.Certainly, change the length of this sleeve pipe 10 itself, just can adjust the spacing between each blade, the stalk of different thicknesses is pulverized effectively so that be suitable for.

Equally, as shown in Figure 3, in this rotating shaft top, string has a plurality of Disintegrating knifes rotationally, and these blades, and the both sides as 5e and 5f are positioned at supporting base make the interval of each blade keep certain, good.

In addition, on turning cylinder 6, depend on the needs, can arrange in every way and fixing many above-mentioned supporting bases and a plurality of Disintegrating knifes that are mounted thereon.

The Disintegrating knife 5 of this device be by wear-resisting band steel through cut-out, punching, grind, thermal treatment forms.The shape and structure of this Disintegrating knife 5 is as shown in Figs. 4a and 4b, and blade 5 itself is rectangle, and can be that an end dashes through hole 13 is arranged, and is ground into the inclined plane along the both sides of blade lengths direction, is beneficial to cut off stalk.In addition, this blade 5 also can be shown in Fig. 5 a and 5b, at two ends Jun Chong through hole 13a and 13b is arranged.Equally, be ground into the inclined plane, be beneficial to cut off stalk along the both sides of blade lengths direction.

The utility model can be assemblied on the various straw cutting apparatuss, can once finish the pulverizing of crops straw and eliminate the root stubble.This reducing mechanism turning radius is about 26 centimetres, rotating speed 1200-2000rpm.

The advantage of this device is: the one, and simple in structure and low in cost is because this device Blade, behind a lateral wearing, turning 180 °, make working face with opposite side, And after end wearing and tearing, the interchangeable other end is as working face. Such one can make cutter Four cuttves use, and cost is reduced greatly. The 2nd, good crushing effect is owing to adopt Straight knife type reducing mechanism, suitable increased blade density, like this crop material Increased by cycle, so just can significantly improve crushing effect. The 3rd, eliminate The root stubble is because this device adopts straight knife type blade, the contact-making surface of blade and stalk Long-pending reducing, simultaneously, the soil-entering resistance of blade is also littler, so, power Consumption reduces, and just allows blade to enter under the soil layer 1-3 centimetre, can be effectively with root The first half of stubble is pulverized, and big upturned soil can not occur when making farming, ploughs thereby improve Make quality. The 4th, improved Crushing ratio, because the Disintegrating knife of this device But under the underground layer 1-3 centimetre, therefore, the maize straw of lodging there is good powder Broken function can not affect crushing effect owing to the lodging of crop material.
