Given this, the purpose of this utility model is to provide a kind of sorting performance good, the secondary finishing thresher that the seed cleannes are higher.
The utility model increases air flow cleaning again one time on the basis of existing air flow cleaning, clean and realize its purpose and become secondary gas flow.
Secondary finishing thresher of the present utility model (referring to accompanying drawing); comprise frame (1); the recessed sieve (4) of threshing cylinder on the frame (3) and below thereof; recessed sieve below is combined into funnel shaped front slide (5) and tail skid (6); there is the selection by winnowing portion of cleaning fan and carrying screw feeder that contains front slide and tail skid below; the winnow (20) that has and carry screw feeder to be communicated with has the secondary selection by winnowing portion of cleaning fan with the secondary of cleaning screw feeder and matching of conveying screw feeder connection that contains between selection by winnowing portion and winnow.
Between an above-mentioned selection by winnowing portion and the secondary selection by winnowing portion wind isolation board (8) that links with front slide (5) and tail skid (6) is arranged, above-mentioned conveying screw feeder is with to clean screw feeder into a single integrated structure, above-mentioned clean fan and secondary to clean fan into a single integrated structure.
Secondary finishing thresher of the present utility model is identical with the threshing course of existing finishing thresher, and its watering and separation procedure is that the secondary fan airstream that carries out continuously for twice is cleaned.
Said structure of the present utility model makes it have following advantage and effect.
One, cleaning screw feeder and cleaning fan structure after a selection by winnowing of the present utility model, constitute secondary selection by winnowing structure, cereal kernel after a selection by winnowing, clean in the course of conveying of screw feeder on the edge, under the effect of cleaning fan airstream, blow separation with remaining in foreign material such as a small amount of standing grain bits in the seed, dust, husk, cereal kernel is through twice air flow cleaning, can reduce percentage of impurity thereby have, improve the advantage of the cleannes of cereal.
Two, conveying screw feeder of the present utility model and clean screw feeder integrative-structure, clean the integrative-structure that fan and secondary are cleaned fan; with the wind isolation board structure; utilize the separation of wind isolation board; form selection by winnowing portion and secondary selection by winnowing portion, thereby have the structure of simplifying the secondary finishing thresher, the advantage that reduces manufacturing cost.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of secondary finishing thresher of the present utility model.Show Fig. 2 A-A sectional structure.
Fig. 2 is the B-B cutaway view of Fig. 1.
Embodiment 1
A kind of secondary finishing thresher of the present utility model, as shown in drawings.Constitute by frame, threshing cylinder, recessed sieve, fan, screw feeder and winnow etc.
Above-mentioned frame 1 is made by the angle steel welding, the frame structure of similar common finishing thresher, and its underpart surrounds cavity shape structure by plate washer all around, and foot rest 3 is arranged at its bottom, and the hood frame (not shown) of common structure can be arranged above frame.
Above-mentioned threshing cylinder 3 is installed on the frame, adopts the common tooth-like threshing roller structure of bow, belt pulley on cylinder shaft and the engine transmission (not shown) that links.
Above-mentioned recessed sieve 4 is common structure, is installed on the frame 1 with usual method, is positioned at the tight below of threshing cylinder 3.
Below recessed sieve 4, adopt common plate shaped front slide 5, tail skid 6, side plate 7, wind isolation board 8 to constitute funnel shaped material-falling hopper, the end opening of material-falling hopper is a drain hole 9.Backboard 10 tops of the frame 1 at tail skid 6 rears are opened and are shaped on the impurity discharging port 11 that communicates with the thresher lower cavity.Between side plate 12 and wind isolation board 8, have every wind top board 13.Above-mentioned wind isolation board 8 is divided into selection by winnowing portion 14 and secondary selection by winnowing portion 15 with the cavity of thresher bottom along the vertical direction of threshing cylinder.
Said fans 16 adopts common structure, is the bottom that axis is arranged on thresher abreast with threshing cylinder, and its length is greater than threshing cylinder.Fan links with threshing cylinder 3 transmissions through driving belt and belt pulley 17.Under the effect of wind isolation board 8, make the air-flow that blows out of fan 16 be blown into selection by winnowing portion 14 and secondary selection by winnowing portion 15 simultaneously.Thereby the leading portion that is blown into the fan 16 of a selection by winnowing portion 14 partly becomes and has the fan of cleaning of once cleaning function, and the back segment of fan partly becomes and has secondary and clean the secondary of function and clean fan.Be that fan 16 is equivalent to clean the structure of fanning the body that unites two into one with cleaning fan and secondary.Can certainly be respectively be provided with respectively and clean fan and secondary is cleaned fan in selection by winnowing portion and secondary selection by winnowing portion.
