Abstract

Abstract A separator for combines has a reel and header, thresher cylinder, conveyor for moving threshed cereal grass, powering means and a housing comprising the combine structure thereof. The separator is comprised of an independently rotatable outer cylinder member having a duct therein and mounted within and powered by the combine. It has an inner cylinder with an air mover also powered by the combine in operation to recirculate air within the separator. In operation the outer cylinder while rotating receives threshed material from the conveyor, disposes same through a distributor to the stalk-grain separator and receives air from the air mover directing same through the duct to the central portion of the member against the outward motion of the grain, separating the grain from its stalk. Air is recirculated within the separator passing from the air mover through the duct, being discharged toward the central portion of the separator, passing through the inner cylinder member and into the air mover. The separator preferably has a dehumidifier having heat transfer coils within the duct and on the outside of the structure. The separator uses rotation and centrifugal force and opposed recirculating airflow to separate threshed cereal grass stalks and grain.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 211 words
In a combine having a reel and header assembly, a thresher cylinder, conveying means for threshed cereal grass therefrom, powering means, and housing means comprising the structure of said combine, therein and therewith the separator means of this invention comprising: a. an outer hollow imperforate member open on its upper and lower portions rotatably mounted on a substantially vertical axis in said combine structure and connected to said powering means to be rotated in operation by same, b. said outer member being in communication with said conveyor means to receive therefrom in operation threshed cereal grass and said outer member having means to direct air radially inward therethrough itself, c. means mounted relative said outer member in operation to recirculate air within said outer member, d. dispersing means and stalk-grain separator means in the upper interior portion of said outer member mounted to and in operation receiving substantially all the threshed grain from said conveyor means in said dispersing means and transferring same to said stalk-grain separator means, e. grain collecting means around said outer member on the lower portion thereof, and f. a plurality of stalk-grain separating members on said stalkgrain separator means which in operation separate grain from its stalk and directs free grain to said grain collecting means.
Claim 2
Dependent Claim 211 words
In a combine having a reel and header assembly, a thresher cylinder, conveying means for threshed cereal grass therefrom, powering means, and housing means comprising the structure of said combine, therein and therewith the separator means of this invention comprising: a. an outer hollow imperforate member open on its upper and lower portions rotatably mounted on a substantially vertical axis in said combine structure and connected to said powering means to be rotated in operation by same, b. said outer member being in communication with said conveyor means to receive therefrom in operation threshed cereal grass and said outer member having means to direct air radially inward therethrough itself, c. means mounted relative said outer member in operation to recirculate air within said outer member, d. dispersing means and stalk-grain separator means in the upper interior portion of said outer member mounted to and in operation receiving substantially all the threshed grain from said conveyor means in said dispersing means and transferring same to said stalk-grain separator means, e. grain collecting means around said outer member on the lower portion thereof, and f. a plurality of stalk-grain separating members on said stalkgrain separator means which in operation separate grain from its stalk and directs free grain to said grain collecting means.
Claim 3
Dependent Claim 164 words
A separator means as described in claim 1, wherein: a. said means mounted relative said combine structure in operation to recirculate air has a fan means rotatably and coaxially mounted about said vertical axis enclosed within said outer member having an inlet within said outer member and a duct means mounted with its outlet, said duct means being said means to direct air inward relative said outer member, b. said fan means is connected to said powering means to be rotated in operation by same independent of said outer member, and c. said means to recirculate air has an inner cylinder member with an imperforate upper surface and a perforate sidewall, said perforate sidewall connected with said fan inlet, in operation said inner cylinder member receiving a portion of said threshed cereal grass from said conveyor means on said upper surface for dispersal to said stalk-grain separator means and said recirculating air is received through said perforate sidewall and passed to said fan means.
Claim 4
Dependent Claim 144 words
A separator means as described in claim 2, wherein: a. said outer member is rotatably attached said combine housing by a normally vertically disposed shaft member along its longitudinal axis, b. said fan means and said inner cylinder member are rotatably attached said vertically disposed shaft by a cylindrical shaft and are adapted to be rotated independently thereof, c. said vertically disposed shaft extends from said inner cylinder member and is rotatably attached said combine housing below said separator means and said cylindrical shaft is attached said vertically disposed shaft within said separator means and attached said combine housing above said separator means, and d. said vertically disposed shaft and said cylindrical shaft are attached said powering means which provides power therefor and has means to vary the rotational speed of said inner cylinder member and said fan means relative to said outer member.
Claim 5
Dependent Claim 84 words
A separator means as described in claim 3, wherein: a. said inner cylinder member has a substantially porous cylinder wall, b. said inner cylinder member has a plurality of elongated blades extending radially from the lower outer portion thereof and said blades substantially span the space between said inner cylinder member and said outer member, and c. said upper surface of said inner cylinder member is generally conically shaped, having the sides thereof concaved and having the apex portion thereof attached said cylindrical shaft.
Claim 6
Dependent Claim 119 words
A separator means as described in claim 4, wherein: a. said duct means has a receiving passageway portion with the inlet in communication with said fan means and having a dispersing passageway portion joined said receiving passageway portion and having a duct outlet positioned to direct air inward relative said separator means, b. said outer member has a perforate inner wall with an opening at said duct outlet in operation to pass air inward relative said separator means through said inner wall opening and pass separated grain outward relative said separator means through said inner wall opening, and c. said grain collecting means is in communication with said inner wall opening in operation to receive grain therefrom said duct.
Claim 7
Dependent Claim 40 words
A separator means as described in claim 5, wherein: a. said separator means has a plurality of said duct means in a spaced relation therearound, and b. said inner wall has a plurality of openings extending therearound connecting said ducts.
Claim 8
Dependent Claim 82 words
A separator means as described in claim 6, wherein: a. said duct means has said duct outlet in the upper portion of said separator means adjacent said stalk-grain separator means, b. said duct means has said duct outlet in the center portion of said separator means, c. said duct means has said duct outlet in the lower portion of said separator means, and d. said grain collecting means has grain moving means therein in operation to move grain to the outlet thereof.
Claim 9
Dependent Claim 55 words
A separator means as described in claim 1, wherein: a. said separator means has a dehumidifier means having a compressor means secured Said outer member, condenser coil means mounted within said separator means and a heat exchanger means mounted on an exterior portion of said outer member, and b. powering means for said compressor means.
