Abstract
The utility model which is an improved design relates to a stubble-crushing and rotary soil-loosening machine. The utility model is characterized in that a power shaft of a rotary cultivator drives a rotary blade through a bevel gear case and a half shaft of a driver housing, and the rotary blade is arranged under a cover of the rotary cultivator; besides, the power shaft is connected with a stubble-crushing knife through the bevel gear case and another half shaft of the driver housing, and the stubble-crushing knife is arranged under a front cover of the rotary cultivator; furthermore, the stubble-crushing knife is hyperbolic, and the stubble-crushing knife is in the shape of a finger and is provided with knife edges; the rotary blade is in the shape of an arrow tip and is provided with the knife edges and arrow tips. 80 percents of roots and stubble can be crushed and evenly mixed with loosened soils of cultivation layers to return to a field only through one operation of the utility model entering the field; water and nutritive substances in the roots and the stubble are enabled to blend into the soils, and the requirement of a seedbed for seeding crops is realized.
Description
The utility model relates to the farmland ploughing equipment, particularly a kind of rotovator.
When ploughing whole ground, except that ploughing, generally use rotovator at present.Existing rotovator loosens the soil with the tulwar rotation, has only about 20% in the broken stubble effect of corn field.Because when rotary tillage, can not be with the chopping of the crop root residue under the face of land, the stubble that can form diameter 15-25cm is honest, influences the sowing of second stubble crop, therefore existing rotary tillage ground can not satisfy the agriculture requirement that stubble-cleaning is ploughed, and also can not make the very high root stubble of nutrient component obtain reasonable use.
The purpose of this utility model is exactly to provide a kind of in rotary tillage, the Stubble-crushing and rotary soil-loosening machine of the effective broken crop root residue of energy.
For reaching the Stubble-crushing and rotary soil-loosening machine that goal of the invention designs, constitute by line shaft and the rotary ploughing cutter shaft that is horizontally placed on the band rotary blade under the hood, line shaft links to each other with the left and right driving semiaxis respectively in bevel gear box, left side jack shaft links to each other with the back hood cutter shaft that unscrews down through uni-drive gear box, right jack shaft linking to each other with broken batch of broken batch of cutter under driving-chain and preceding hood.
The utility model has been because existing rotovator has been set up broken stubble cutter shaft and the broken stubble cutter preceding hood under, so the crop root residue under can the broken effectively face of land, and the effect of loosening the soil is also better.This machine only once advances the ground operation, mixes also field thoroughly with regard to the root stubble of energy broken 80% and with the topsoil soils that unscrews, and makes moisture, nutrient in the root stubble incorporate soil, reaches the kind bed requirement of crop sowing.
In order to improve the broken stubble and the effect of loosening the soil, the soil that unscrews that the utility model Stubble-crushing and rotary soil-loosening machine unscrews on the cutter shaft can be the arrowhead-shaped unscrewing knife that blade and arrow are arranged, but and mounted in pairing mode shape symmetry on the broken stubble cutter shaft, has the hyperbolic of blade to refer to the type stubble breaking knife.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment Stubble-crushing and rotary soil-loosening machine schematic side view.
Fig. 2 is the utility model embodiment schematic top plan view.
Fig. 3 refers to type stubble breaking knife schematic diagram for hyperbolic.
Fig. 4 is arrowhead-shaped unscrewing knife schematic diagram.
As shown in Figure 1 and Figure 2, the bevel gear of line shaft 1 in bevel gear box 5 of the utility model Stubble-crushing and rotary soil-loosening machine links to each other with left jack shaft 12, the left side travelling gear 6 of jack shaft 12 in uni-drive gear box links to each other with the cutter shaft 8 that unscrews under the hood 10 of back, and unscrews as shown in Figure 4 arrowhead-shaped of installation on the cutter shaft 8 and unscrews native 7.Right jack shaft 11 refers to that through 9 times bands of driving-chain 4 and preceding hood hyperbolic as shown in Figure 3 the broken stubble axle 3 of type stubble breaking knife 2 links to each other.
Figure 3 shows that hyperbolic refers to one of type stubble breaking knife 2, with another cutter mounted in pairing mode of its symmetry, hyperbolic refers to that blade 13 is arranged on the type stubble breaking knife 2.
Figure 4 shows that arrowhead-shaped unscrewing knife 7, blade 14 and arrow 15 are arranged on it.
Claims (3)
1, Stubble-crushing and rotary soil-loosening machine, constitute by line shaft and the rotary ploughing cutter shaft that is horizontally placed on the band rotary blade under the hood, line shaft links to each other with rotary ploughing cutter shaft through bevel gear box, transmission mechanism, it is characterized in that said line shaft links to each other with the left and right driving semiaxis respectively in bevel gear box, left side jack shaft links to each other with the back hood cutter shaft that unscrews down through uni-drive gear box, right jack shaft linking to each other with broken batch of broken batch of cutter under driving-chain and preceding hood.
2, Stubble-crushing and rotary soil-loosening machine according to claim 1 is characterized in that the said unscrewing knife that unscrews on the cutter shaft is the arrowhead-shaped unscrewing knife that blade and arrow are arranged.
