Abstract

The utility model discloses an efficient stubble cleaning mechanism, relating to the field of agricultural machinery. The efficient stubble cleaning mechanism comprises a case assembly and a tilling blade assembly, wherein the tilling blade assembly is matched with the case assembly; the tilling blade assembly comprises a stubble crushing knife and a knife rest shaft matched with the stubble crushing knife; the stubble crushing knife comprises a straight arc-shaped knife handle; the front end of the arc-shaped knife handle is fixedly connected with a tool bit; the tool bit comprises two triangular blades; two triangular blades are symmetric; the opposite bottom ends of the two blades are fixedly connected; the orientation of the inclined end of each blade is consistent to the direction of an arc-shaped bulge of an arc-shaped knife body; an inclined cutting edge is arranged on the port of the inclined end of the blade, and an inclined angle between the two blades is 90-150 degrees. According to the mechanism, straws in any sizes can be effectively cut, with good cutting effect and fine cutting.

Description

A kind of efficient stubble-cleaning mechanism

Technical field

The utility model relates to agricultural mechanical field.

Background technology

In the traditional farming farming, the peasant can regain the stalk of crops and go, and is used as life fuel or animals feed, along with the improvement of living condition; The peasant no longer makes domestic energy with stalk, and new sub-district, rural area all makes electricity consumption, liquefied gas, natural gas etc. as the energy, and the straw utilization rate is very low; It has just become agriculture discarded object, and the peasant sows prior to seeding for ease; Generally all can incinerate stalk, crop straw burning one is to cause air pollution, the 2nd, and destroy soil, cause soil compaction etc.

At present, government advocates straw-returning, has the rotovator of employing to turn over together with stalk now; Because traditional rotovator, blade for stubble ploughing machine do not have cutting edge, can not stalk effectively be shredded, the stalk volume of its cut-out is still bigger; The rotovator stalk that will break mixes and stirs together and buries, and causes local soil by built on stilts like this, and the peasant after planting; The seed that drops on the built on stilts soil can not absorb moisture for a long time fully, and the moisture that it can only utilize built on stilts top causes seed not germinate like this; The back seed that perhaps germinates begins atrophy death, and per unit area has a lot of seeds can not Cheng Miao; Modal solution increases thickness of sowing exactly, promptly increases the seed consumption, and this mode can not be dealt with problems, and makes that on the contrary the seedling amount on other normal soil is too many, and it is bad to grow.

Summary of the invention

The utility model provides a kind of efficient stubble-cleaning mechanism, and purpose is that the stalk that solves existing field can't handle, and influences the problem of crop growth.

The utility model comprises the casing assembly, ploughs the cutter assembly, said cultivated cutter assembly be engaged in said casing assembly on, said cultivated cutter assembly comprises broken stubble cutter, the tool axis that cooperates with broken batch of cutter; Said broken stubble cutter comprises straight arc handle of a knife; Front end at said arc handle of a knife is fixedly connected cutter head, and said cutter head comprises two triangular blades, said two triangular blade symmetric arrangement; The relative base end of said two blades is mutually permanently connected; The hypotenuse end of said each blade towards consistent with the direction of the arc convex of said arc cutter hub, at the port of said blade hypotenuse end the cutting edge of inclination is set, the angle between said two blades is 90 °～150 °.

The utility model has the left and right sides tulwar of longer cutting edge to change system into straight arc tulwar original blade head-bent, external arc, and its external arc also is provided with cutting edge, and cutter head is arranged to the dihedral cutter head; And the cutter head outer rim is provided with cutting edge; This cutter head cut surface broad, the cutter head of dihedral has the cutter distance of gradual change, and no matter great stalk can both effectively cut; And good cutting effect is cut more broken.

The utility model is provided with driven grid roller at the rear of said cultivated cutter assembly, said driven grid roller is pulled at the rear of said casing assembly, and said driven grid roller is provided with some steel bars that are uniformly distributed with and are parallel to each other, the port of said steel bar towards radially the position; Driven grid roller is set can knocks driven grid roller down with ploughing cutter assembly soil and the crushing straw that turns over that retroject, the heavier meeting of soil falls along the direction that driven grid roller advances, and crushing straw is more clear; The distance of being dished out is shorter, generally all drops on the place ahead of soil, and the soil that falls at rear always covers on the crushing straw like this; And through the effect of driven grid roller, crushing straw continuously is pressed under the soil layer, because crushing straw is thinner; Soil is also thin, so less by built on stilts space, natural water evaporates seldom; When this stubble-cleaning mechanism was used on the sower, after seed was sowed, seed was broadcast in appropriate depth, and in the soil that moisture suits, bud ratio naturally will be high.

The utility model is provided with a bracing piece between said two blades, the two ends of said bracing piece are separately fixed at the medial surface of said two blades; Bracing piece makes cutter head more firm, and prolong its service life.

Said two blades of the utility model are for being wholely set or the split setting; Being wholely set soon, an isosceles triangle is that break is pulled foldable type with the symmetry axis; The split setting promptly has two fixedly moulding of triangle lamellar body welding.
