Abstract
A novel blade for a combine-harvester comprises a blade body, blade edges and a blade assembling structure, wherein the blade body is in a trapezoid shape, the blade edges are arranged on the upper portions of the bevel edges of the trapezoid respectively, the blade assembling structure is arranged on the lower portion of the trapezoid, on each bevel edge of the trapezoid, the ratio of the length of the portion where each blade edge is located to the length of the portion where each blade edge is not located is between 7:1 and 12:1, and sawteeth are arranged on the blade edges. According to the technical scheme, blade portions with appropriate proportion lengths are adopted, as much as straw is cut when the blade rotates by a circle, the amount of the straw is not too large, and therefore the straw is not wound on a cutter shaft. The sawteeth improve the cutting effect and drive the cut straw to achieve a throwing effect.
Description
Technical field
The utility model belongs to field of agricultural machinery, is specifically related to the special-purpose blade of a kind of combine.
Background technology
In the prior art, threshing cylinder parts and the stalks cutting of rice/wheat combine arrange respectively.In the prior art, the effect of stalks cutting is undesirable, the size of the stalk after the shearing long (reaching more than the 30cm), overweightly causes shedding inhomogeneous, and the distribution in the arable land is too concentrated, grows pathogenic bacteria etc. easily.
The utility model content
In order to solve the above-mentioned problems in the prior art, the utility model proposes the special-purpose blade of a kind of new combine, comprise blade body, blade and blade assembly structure; Being shaped as of described blade body is trapezoidal, and blade is on the top of trapezoidal hypotenuse, and the blade assembly structure is in trapezoidal bottom; On the described trapezoidal hypotenuse, blade place partial-length and non-blade place partial-length ratio are 7:1～12:1; Blade is provided with sawtooth.(principle of this technological means is, adopts the knife edge part of proper ratio length, and when blade rotated a circle, the stalk of cutting was many as far as possible, and, be unlikely to too many again, cause stalk to be wrapped on the cutter axis.Sawtooth except improving cutting effect, can also arrive the effect of shedding with the stalk after the cutting.）
Described sawtooth is in the first half of blade, and on the described trapezoidal hypotenuse, and blade is provided with that not have the length ratio of serrated portion on the length of serrated portion and the blade be 1:2～3:1.(principle of this technological means is, fully takes into account the requirement of stalk quantity in time of shedding and unit interval, accomplishes to throw movingly, throws evenly.）
Blade body be shaped as isosceles trapezoid.(principle of this technological means is make cutterhead rotate rotating and all can use, and effect to be identical.）
Section along the hatching gained of blade is isosceles trapezoid, and this hatching is parallel with the trapezoidal upper and lower end of blade body.(principle of this technological means is make cutterhead rotate rotating and all can use, and effect to be identical.）
The blade assembly structure is through hole.(principle of this technological means is to be assemblied in blade on the cutterhead easily.）
Beneficial effect: on blade of the present utility model being attached to behind the stalks cutting cutterhead of combine, the stalk length that the cutterhead cutting obtains can be controlled in 10cm, and stalk is cut very brokenly, is conducive to throw and looses.
Description of drawings
Fig. 1 is the structural representation of the utility model blade;
Fig. 2 is the schematic cross-section of the utility model blade.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model:
As Fig. 1, the special-purpose blade of a kind of new combine comprises blade body 1, blade 2 and blade assembly structure; Being shaped as of described blade body 1 is trapezoidal, and blade 2 is on the top of trapezoidal hypotenuse, and the blade assembly structure is in trapezoidal bottom; On the described trapezoidal hypotenuse, blade 2 place partial-lengths and non-blade place partial-length ratio are 7:1～12:1; Blade 2 is provided with sawtooth 3.
Described sawtooth 3 is in the first half of blade, and on the described trapezoidal hypotenuse, and blade 2 is provided with that not have the length ratio of serrated portion on the length of serrated portion and the blade 2 be 1:2～3:1.
As Fig. 2, be isosceles trapezoid along the section of the hatching gained of blade, this hatching is parallel with the trapezoidal upper and lower end of blade body.
The blade assembly structure is through hole 4.
Claims (5)
1. the special-purpose blade of combine comprises blade body, blade and blade assembly structure; Being shaped as of described blade body is trapezoidal, and blade is on the top of trapezoidal hypotenuse, and the blade assembly structure is in trapezoidal bottom; On the described trapezoidal hypotenuse, blade place partial-length and non-blade place partial-length ratio are 7:1～12:1; Blade is provided with sawtooth.
2. the special-purpose blade of combine according to claim 1, it is characterized in that described sawtooth is in the first half of blade, and on the described trapezoidal hypotenuse, blade is provided with on the length of serrated portion and the blade does not have the length ratio of serrated portion to be: 1:2～3:1.
