Abstract
The utility model relates to a novel reciprocating type cutting blade of thick and stiff crop straw, the front axle shape of this blade is the circular arc type. Circular arc type front axle is tangent with the cutting edge line of blade both sides. This blade can guarantee thick and stiff crop straw when contacting with cutting blade front axle, the smooth cutting district that gets into has solved the problem that straw that the reciprocating type cutting blade of current standard form takes place was overturned forward by linear type front axle when the thick and stiff crop straw of cutting. This cutting blade both can regard as the knife section of reciprocating cutterbar to use, also can regard as the shim of reciprocating cutterbar to use, can effectively reduce cutting height with a batch quality is cut in the improvement, had characteristics such as simple structure, easy manufacturing, safe and reliable, had better practicality and popularization prospect.
Description
One, technical field
The present invention relates to a kind of novel thick and stiff crops straw reciprocal cutting blade, belong to agricultural machinery and equipment field.
Two, background technology
Crops straw cutting results are important steps for production estimation, and therefore, the research of crops straw cutter have also been obtained to be greatly developed.Current most widely used cutter is reciprocating cutterbar, and defines standard.The standard type cutting blade of reciprocating cutterbar can complete the cutting of thin, the soft shape stalk such as wheat, paddy rice smoothly, but when thick and stiff crops straws such as cutting rod mulberry, cotton stalk, broomcorn straws, easily stalk is pushed over forward, stalk can not be made successfully to enter cutting area and to complete cutting, thus cause stalk to be cut by multitool, cut the problems such as stubble is of poor quality, cutting height uprises, blade abrasion is serious.This is mainly because bridge shape is linear pattern before standard type reciprocal cutting blade.
Particularly for bar mulberry, when carrying out mechanized harvest, ensure to cut stubble smooth, not tearing phenomenon, if to cut stubble of poor quality for bar mulberry, then can affect the output of mulberry leaf, and affect silkworm and mulberry economic benefit further.Current standard type reciprocal cutting blade easily reduces bar mulberry and cuts a batch quality, is not well positioned to meet thick and stiff crops straw split requirement.
Three, summary of the invention
For solving the problem, the invention provides a kind of novel thick and stiff crops straw reciprocal cutting blade, propons is designed to circular arc by the present invention on the basis of the linear pattern propons of existing standard type reciprocal cutting blade; Make propons into be connected with edge line is tangent simultaneously; This blade can improve and cuts a batch quality, reduces cutting height and blade abrasion degree, and the present invention also can be used for thin as wheat, paddy rice etc., the soft shape stalk of cutting.
For achieving the above object, the invention by the following technical solutions:
A kind of thick and stiff crops straw reciprocal cutting blade, comprises cutter hub, also comprises the blade propons of cutter hub front end and the blade of cutter hub both sides; It is characterized in that, before the blade of cutter hub front end, bridge shape is circular arc type; The edge line of circular arc type propons and cutter hub both sides is tangent; Blade is light sword or land.The knife section that namely this blade can be used as reciprocating cutterbar uses, and the ledger-plate that also can be used as reciprocating cutterbar uses.
When adopting this blade to carry out reciprocating cutting results to thick and stiff crops straw, when stalk does not enter and do not enter cutting area completely time, stalk is when contacting with the propons of reciprocal cutting blade, the propons of circular arc type can enable thick and stiff crops straw be slides quickly into cutting area along circular arc type propons, avoid occurring that the phenomenon that stalk is pushed forward down occurs, thus a batch quality is cut in raising, reduce cutting height and blade abrasion degree.
Four, accompanying drawing explanation
Fig. 1 is the structure chart of the thick and stiff crops straw reciprocal cutting blade of the present invention;
In figure: 1. installing hole 2. blade 3. circular arc type propons
Five, embodiment
The correlation technique content do not addressed below all can adopt or use for reference prior art.
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
A kind of thick and stiff crops straw reciprocal cutting blade, comprises cutter hub, also comprises the blade propons of cutter hub front end and the blade of cutter hub both sides; It is characterized in that, before the blade of cutter hub front end, bridge shape is circular arc type; The edge line of circular arc type propons and cutter hub both sides is tangent; Blade is light sword or land.The knife section that namely this blade can be used as reciprocating cutterbar uses, and the ledger-plate that also can be used as reciprocating cutterbar uses.
When adopting this blade to carry out reciprocating cutting results to thick and stiff crops straw, when stalk does not enter and do not enter cutting area completely time, stalk is when contacting with the circular arc type propons 3 of reciprocal cutting blade, circular arc type propons 3 can enable thick and stiff crops straw be slides quickly into cutting area along circular arc type propons 3, avoid appearing at the phenomenon that when utilizing standard type reciprocal cutting blade to cut thick and stiff crops straw, stalk is pushed over forward by linear pattern propons, thus a batch quality is cut in raising, reduce cutting height and blade abrasion degree.
The present invention reaches the phenomenon avoiding thick and stiff crops straw to be pushed over forward by reciprocal cutting blade propons in cutting process and occurs, improves the object of cutting a batch quality, reducing cutting height and blade abrasion degree, have structure simple, be easy to features such as manufacturing, safe and reliable, there is good practicality and promotion prospect.
The above is only the preferred embodiment of the application, those skilled in the art is understood or realizes the application.To be apparent to one skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the application, can realize in other embodiments.Therefore, the application can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. a thick and stiff crops straw reciprocal cutting blade, comprises cutter hub, also comprises the blade propons of cutter hub front end and the blade of cutter hub both sides; It is characterized in that, before the blade of cutter hub front end, bridge shape is circular arc type; The edge line of circular arc type propons and cutter hub both sides is tangent; Blade is light sword or land.
2. blade as claimed in claim 1, it is characterized in that, this blade can use as the knife section of reciprocating cutterbar, also can use as the ledger-plate of reciprocating cutterbar.
