Abstract

The utility model relates to an energy-saving knife roll used for a stubbing machine. At present, the cutter of a knife roll of a stubbing machine deforms or fractures easily, the energy consumption is large, and the stubbing machine has large self vibration and is not reposeful. The energy-saving knife roll provided by the utility model is characterized in that soil smashing cutters are arranged on a cutter holder of a knife hub with the blade part facing to the outer side; a plurality of stubble smashing cutters are arranged on two side surfaces of a cutter disk in an equivalent, staggered and uniform manner, wherein the included angle between a cutter handle and a cutting board is an acute angle; the mounting angles of the stubble smashing cutters are less than 20 degrees; and the knife roll is constituted by handle protecting cutters mounted at the bent heads of the cutter handles of the stubble smashing cutters. The stubble smashing cutters and the handle protecting cutters are arranged in an centralized manner through the intermediate cutter disk so as to be favor of stubble smashing and soil loosening and to reduce the resistance that the knife roll enters soil; included angles between the cutter handles and the cutting boards of the stubble smashing cutters are acute angles, so that the cutters do not deform or fracture easily; compared a stubbing machine adopting the energy-saving knife roll with a stubbing machine adopting a conventional knife roll, a large number of field experiment prove that oil consumption can be saved by 50% per mu, so that the purpose of saving a great amount of energy can be achieved.

Description

Energy-conservation rotor

Technical field

The utility model relates to a kind of stubble cleaner, particularly relates to a kind of energy-conservation rotor that is used for stubble cleaner.

Background technology

At present; The rotor that known stubble cleaner uses is intrinsic 4～5 cutterheads on the roll wheel; Be uniformly distributed with 3～6 on each cutterhead separately cutting knife, its sword plate face and sword limit surface of revolution tangent line angle constitute greater than 30 ° cutting knife, and the penetrating angle of this rotor cloth cutter is unreasonable; Cutting knife excessively stirs soil, throws soil and measures excessive; Because what cutting knife adopted when folding is the obtuse angle, when causing the cutting knife operation, point of a knife buries earlier, and point of a knife partly weares and teares excessive, and it is big that handle of a knife receives moment of rupture, and is yielding or fracture; The cutting knife that this rotor is arranged, the quantity that is used for broken stubble is very few, and the quantity that is used for hack is too much; Many reasons make this rotor cutting blade abrasion big, and the energy consumption that idle work causes during rotor work is excessive, and operating efficiency is low, causes small tractor can not drive the stubble cleaner normal operation, and stubble cleaner self vibration is big, not steady.

Summary of the invention

In order to overcome above-mentioned technical deficiency; The utility model provides a kind of energy-conservation rotor that is used for stubble cleaner; Simple in structure and the cloth cutter of this energy-conservation rotor is reasonable, and the installation form and the cutting knife self structure selection of parameter of the quantity of cutting knife, cutting knife are reasonable, reliable operation, durable; The stubble-cleaning rate is high, and it is effective to loosen the soil.

For solving its technical problem; The technical scheme that the utility model adopted is: by a cutterhead that is equipped with in the middle of axle sleeve, the axle sleeve; And both sides are equipped with separately and are used to install 1～2 cutter hub that constitutes the tool rest of hack cutting knife; Blade hack cutting knife toward the outer side is installed on the tool rest, and equivalent is staggered on the two sides of cutterhead evenly installs several handles and is done by the forging of band steel folding, the broken batch of cutting knife that has the sword plate on sword limit to form by a handle of a knife and a side; The angle that is converted between handle of a knife and sword plate is an acute angle, and the sword plate face of broken stubble cutting knife and its sword limit surface of revolution tangent line angle are less than 20 °; Each broken stubble cutting knife handle of a knife bending head has to be bent into the protect handle cutting knife (3) of handle of a knife side less than 30 ° of angles and constitutes.

The beneficial effect of the utility model is: this energy-conservation rotor, adopt broken stubble and the equally distributed form of hack cutting knife by original stubble cleaner rotor, and a fairly large number of broken stubble cutting knife of cutterhead centralized arrangement in the middle of becoming, a small amount of hack cutting knife is arranged at the rotor two ends; The handle cutting knife of installing on the broken stubble cutting knife that protects is beneficial to broken stubble and loosens the soil, and can alleviate broken stubble cutting knife soil-entering resistance, adopts less penetrating angle when installing owing to broken stubble cutting knife; Reduced stirring and throwing soil amount to soil, reduced useless power consumption, broken stubble cutting knife is concentrated even the layout; Can must improve the breaking capacity to the crop rhizome largely, make the rotor operation steady, be acute angle because broken stubble cutting knife handle of a knife and knife plate be converted into; Bury in the handle of a knife head after making point of a knife, alleviated the stressed of point of a knife and wearing and tearing, make the not yielding and fracture of broken stubble cutting knife; Thereby energy-conservation rotor has been realized, efficient is high, and energy consumption is low; Reliable operation, broken stubble rate is high, adopts the stubble cleaner of the energy-conservation rotor of present technique; Compare with the stubble cleaner that uses the prior art rotor through a large amount of field experiments, can save 50% fuel consumption for every mu, thereby realize the purpose of a large amount of energy savings.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the energy-conservation rotor of the utility model.

Fig. 4 is the C-C generalized section of Fig. 3.

Among the figure 1, broken stubble cutting knife, 2, the hack cutting knife, 3, protect the handle cutting knife, 4, axle sleeve, 5, cutterhead, 6, tool rest.

Embodiment

By being equipped with a cutterhead (5) in the middle of axle sleeve (4), the axle sleeve (4); And both sides are equipped with separately and are used to install 1～2 cutter hub that constitutes the tool rest of hack cutting knife (2) (6); Tool rest (6) is gone up blade hack cutting knife (2) toward the outer side is installed; Equivalent is staggered on cutterhead (5) two sides evenly installs several handles and is done by the forging of band steel folding, by the broken batch of cutting knife (1) that a handle of a knife and a side have the sword plate on sword limit to form, is converted between sword handle and sword plate and is acute angle; The sword plate face of broken stubble cutting knife (1) and its sword limit surface of revolution tangent line angle be less than 20 °, and the handle of a knife of each broken stubble cutting knife (1) bending head all has to be bent into the handle of a knife side and protects handle cutting knife (3) formation less than 30 ° of angles.
