Description
Technical field
The utility model relates to the cleaning plant of combine, particularly relates to a kind of sieve of combine.
Background technology
Existing combine has been widely used in agricultural production, especially wheat, paddy rice etc. use grain header in a large number when gathering in, and operationally, crop is transported to threshing in threshing chamber to grain header, grain (rice, wheat etc.) after threshing, after cleaning plant screening, enters feed bin.Existing cleaning plant upper strata adjustable fin and lower screen (lower screen mostly is plane stamped sieve, wire gauze sieve) form cleaning plant, and are positioned at the middle part of vibratory sieve, adjustable fin is made up of polylith sieve and support, existing sieve generally adopts metal, Heavy Weight, increases the load of vibratory sieve; Simultaneously when making metal sieve, need time processing just can become finished product more, as: its two ends need punch forming, then by stamping forming two ends welding bayonet lock, for being connected with frame, and sieve work under bad environment, because wearing away paint, corrosion will be produced, because adjustable fin needs to regulate once use, use rear corrosion to regulate effort, damage type mostly is fracture and corrosion.
China Patent No. is separately had to be: 200920249818.1 disclose the adjustable cleaning sieve for combined harvester of a kind of sieve, comprise screen frame, be fixed on the import grid at screen frame two ends, outlet grid, screen frame between import grid and outlet cells is provided with plumage squama sieve, be fixed with gear in the screen frame bottom of outlet grid side, plumage squama sieve is hinged in rotating shaft; Be provided with the adjusting device be made up of regulating handle and sector rack between screen frame and gear, regulating handle is hinged on bolt mutually meshing with sector rack; There is multiple adjusting position, by the rotation of regulating handle, the plumage squama sieve be hinged in rotating shaft can be driven; Above-mentioned patent is object is by adjusting device, and then regulates the size in sieve aperture, can select the aperture be applicable to according to actual needs, satisfy the demand.
Utility model content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of sieve of combine, and this sieve profit is made of plastic, arranges reinforcement simultaneously, do not need secondary operations, improve production efficiency, reduce cost in sieve.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of sieve of combine, comprise sieve body, described sieve body is provided with squama tooth, it is characterized in that: described sieve is that plastics are made, sieve body is provided with cross reinforcing along its length, sieve body is also provided with cross reinforcing orthogonal waling, the two ends of described sieve body are provided with fixed pin holes.
Described cross reinforcing is two, and the length direction along sieve body be arranged in parallel, and described waling is connected with two cross reinforcings respectively.
The middle part of described cross reinforcing raises up and forms the reinforcement of arch.
The fixed pin holes be positioned on the upside of sieve body is upper fixed pin holes, fixed pin holes under being of downside, and described upper fixed pin holes is blind hole, the through hole that lower fixed pin holes is separated in being.
Described sieve body, cross reinforcing, waling and fixed pin holes are integrally formed by mould.
The utility model has the following advantages:
1, sieve of the present utility model is that plastics are made, and sieve body is provided with cross reinforcing along its length, sieve body is also provided with the orthogonal waling with cross reinforcing, and the two ends of described sieve body are provided with fixed pin holes.The sieve adopting engineering plastics to make is lightweight, and heat resistance is good, and the coefficient of friction of engineering plastics is little, more laborsaving when regulating; Without the need to repeatedly processing, one-shot forming, improves production efficiency, reduces cost; Sieve arranges cross reinforcing behind simultaneously, then is coupled together by vertical reinforcement, adds the intensity of sieve entirety, avoids fracture.
2, cross reinforcing of the present utility model is two, length direction along sieve body be arranged in parallel, described waling is connected with two cross reinforcings respectively, and the middle part of cross reinforcing raises up and forms the reinforcement of arch, strengthens the intensity of sieve entirety further.
3, the fixed pin holes on the upside of sieve body of the present utility model is upper fixed pin holes, fixed pin holes under being of downside, described upper fixed pin holes is blind hole, the through hole that lower fixed pin holes is separated in being, upper fixed pin holes be used for be connected with support, lower fixed pin holes be in separated through hole connected by floor.
4, sieve body of the present utility model, cross reinforcing, waling and fixed pin holes are integrally formed by mould, and because sieve adopts engineering plastics to make, be therefore integrally formed by mould, production efficiency is high, and quality is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the B-B direction view of Fig. 1;
Mark in figure: 1, sieve body, 2, squama tooth, 3, cross reinforcing, 4, waling, 5, upper fixed pin holes, 6, lower fixed pin holes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of sieve of combine, comprises sieve body 1, and described sieve body 1 is provided with squama tooth 2, and sieve of the present utility model is that plastics are made, and adopts engineering plastics; Sieve body 1 is provided with cross reinforcing 3 along its length, (said length direction is exactly the orientation of squama tooth, and be located at the behind of sieve) sieve body 1 is also provided with the orthogonal waling 4 with cross reinforcing 3, the two ends of described sieve body 1 are provided with fixed pin holes.
Further, described cross reinforcing 3 is two, and two cross reinforcings 3 be arranged in parallel along the length direction of sieve body, and described waling 4 is laterally strengthened 3 muscle with two respectively and is connected.
Further, the middle part of described cross reinforcing 3 raises up and forms the reinforcement of arch.Coupled together by vertical reinforcement again, add the intensity of sieve entirety, avoid fracture.
Further, about fixed pin holes, the fixed pin holes be positioned on the upside of sieve body is upper fixed pin holes 5, fixed pin holes 6 under being of downside, and described upper fixed pin holes 5 is blind hole, the through hole that lower fixed pin holes 6 is separated in being.Upper fixed pin holes be used for be connected with support, lower fixed pin holes be in separated through hole connected by floor.
Described sieve body 1, cross reinforcing 3, waling 4 and fixed pin holes are integrally formed by mould.
The sieve that above-mentioned employing engineering plastics are made is lightweight, and heat resistance is good, and the coefficient of friction of engineering plastics is little, more laborsaving when regulating; Without the need to repeatedly processing, one-shot forming, improves production efficiency, reduces cost; Sieve arranges cross reinforcing behind simultaneously, then is coupled together by vertical reinforcement, adds the intensity of sieve entirety, avoids fracture.
