Abstract
The utility model relates to grain header, particularly a kind of sorting screen and sieve thereof being applicable to grain header.The utility model is achieved by the following technical programs: a kind of sieve being applicable to grain header, comprising the carrier of the working face had for accepting effect, being located at the screening unit of described carrier upper surface, described working face has and all arranges and the fin be parallel to each other and groove along described carrier length direction, and described fin and described groove distribute alternately.The utility model has intensity well, and structure is simple, and technique is simple, and cost is lower.
Description
Technical field
The utility model relates to grain header, particularly a kind of sorting screen and sieve thereof being applicable to grain header.
Background technology
Sorting screen of the prior art, if Authorization Notice No. is a kind of sorting screen disclosed in the utility model patent of CN203708858U, but, the structure of the sieve of this kind of sorting screen often as shown in Figure 1, for strengthening the intensity of sieve, in sieve, be often fixed with a reinforcement 5 extended along sieve length direction; Thus cause preparation technology to bother, and cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of sieve being applicable to reaping machine grading sieve, and it has intensity well, and structure is simple, and technique is simple, and cost is lower.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of sieve being applicable to grain header, comprising the carrier of the working face had for accepting effect, being located at the screening unit of described carrier upper surface, described working face has and all arranges and the fin be parallel to each other and groove along described carrier length direction, and described fin and described groove distribute alternately.
As preferably of the present utility model, the two ends of described carrier are fixedly connected with two respectively in the bearing pin distributed up and down; Described bearing pin is fixedly connected in described groove.
As preferably of the present utility model, described screening unit is the length direction multiple screening tooth spaced apart along described carrier; And the upper end of described screening tooth is plane.
Another object of the present utility model is to provide a kind of sorting screen being applicable to grain header, comprises the sieve as described in technique scheme.
As preferably of the present utility model, this kind of sorting screen comprises framework, the screening assembly be located in described framework; Described screening assembly comprises and to be arranged in parallel and upper end is rotationally connected with described frame side wall and the multiple described sieve linked all mutually in lower end, be rotationally connected with the adjustable plate of described frame side wall; The bottom of described adjustable plate is linked in the lower end of described sieve; The upper end of described adjustable plate has arc groove, is provided with the screw that described adjustable plate can be fixed on described framework in described arc groove; Described working face is all the time in arranging obliquely.
In sum, the utility model has following beneficial effect: working face has fin and groove, screening unit directly should be arranged at the upper end of corresponding fin or groove place part, thus make operationally, the tooth of screening unit is being subject to acting on the resistance given, can by fin or groove absorb, and the setting of fin and groove, also make working face have elastic deformation more well, and then strengthen the intensity of sieve; On the other hand, due to sieve operationally, working face all the time in arranging obliquely, therefore, also due to fin and the setting of groove, and crop is fallen speed be obstructed, thus improve the holdup time of crop on sorting screen, be beneficial to raising and clean screening effect; Consider from technique, the formation of fin and groove, also only need be once-forming by roller press roll extrusion, therefore technique is also comparatively simple, and cost is lower; And due to the forming technology of working face fin and groove comparatively simple, also make a block plate only need therefrom cut by the shape of screening tooth, namely by rolling forming, thus a block plate can form two sieves comparatively simply; And, in the prior art for increasing the intensity of sieve bottom, a reinforcement perpendicular to sieve length direction need be set again at the two ends place of sieve toward contact, and the utility model is due to the setting of fin and groove, the bottom of sieve is also the same with top has intensity well, therefore without the need to arranging reinforcement again.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present utility model.
Embodiment: as in Figure 2-4, a kind of sorting screen being applicable to grain header, comprises framework 3, the screening assembly be located in framework 3.
Screening assembly comprises and to be arranged in parallel and upper end is rotationally connected with framework 3 sidewall and multiple sieves of linking all mutually in lower end, is rotationally connected with the adjustable plate 41 of framework 3 sidewall;
The bottom of adjustable plate 41 is linked in the lower end of sieve; The upper end of adjustable plate 41 has arc groove 411, is provided with the screw that adjustable plate 41 can be fixed on framework 3 in arc groove 411; Screw is not shown in the drawings.
Sieve comprises the carrier 1 of the working face 11 had for accepting crop, and the upper surface of carrier 1 is provided with screening unit 2; The general not stainless steel of material of working face 11.
Working face 11 has and all arranges and the fin 111 be parallel to each other and groove 112 along carrier 1 length direction, and fin 111 and groove 112 distribute alternately.
The two ends of carrier 1 are fixedly connected with two respectively in the bearing pin 12 distributed up and down; Bearing pin 12 is fixedly connected in groove 112.
Screening unit 2 is the length direction multiple screening tooth 21 spaced apart along carrier 1; And the upper end of screening tooth 21 is plane.
Under duty, working face 11 is all the time in arranging obliquely.
