Abstract
Abstract A huller operating for separating hulled rice and unhulled rice and recirculating the unhulled rice to the supply hopper of the hull after husking it therein. To this end, the huller comprises a sorting or separating pan having a rough sorting surface and having the supply side in a higher elevation than the discharge side, a reciprocating device for reciprocating said pan in an obliquely upward direction when seen in front elevation, a vibration conveyor mounted integrally with the pan on the takeout opening for the separated unhulled rice and adapted to be reciprocated by reciprocation of said sorting pan, hulling means provided below the discharge opening of said vibration conveyor, and means for recirculating the rice thus husked to the supply side of the pan.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
267 words
In a huller comprising: separating means for separating hulled grain from unhulled grain, including: a separating pan having a rough sorting surface and a supply side and a discharge side, said supply side being elevated above said discharge side; a first discharge opening for hulled grain located in said discharge side; a second discharge opening for a mixture of hulled grain and unhulled grain located in said discharge side; a third discharge opening for unhulled grain located in said discharge side; said separating pan being further inclined such that said first discharge opening is elevated above second discharge opening and said second discharge opening is elevated above said third discharge opening; means for reciprocating said separating pan in an obliquely upward direction with reference to the plane of said sorting surface; means adjacent said supply side for supplying hulled and uNhulled grain to said separating surface; means for removing said hulled grain from said first discharge opening; means for removing said mixture from said second discharge opening; and means for removing said unhulled grain from said third discharge opening; the improvement wherein said means for removing said unhulled grain comprises: a vibration conveyor integrally mounted at one end thereof to said hulled grain discharge opening, said vibration conveyor being reciprocated by said means for reciprocating said separating pan; a discharge funnel at the other end of said vibration conveyor; said reciprocating vibration conveyor being operative to laterally upwardly transfer said unhulled grain from said unhulled grain discharge opening to said discharge funnel; and hulling means spaced below said discharge funnel to receive and hull said unhulled grain.
Claim 2
Dependent Claim
267 words
In a huller comprising: separating means for separating hulled grain from unhulled grain, including: a separating pan having a rough sorting surface and a supply side and a discharge side, said supply side being elevated above said discharge side; a first discharge opening for hulled grain located in said discharge side; a second discharge opening for a mixture of hulled grain and unhulled grain located in said discharge side; a third discharge opening for unhulled grain located in said discharge side; said separating pan being further inclined such that said first discharge opening is elevated above second discharge opening and said second discharge opening is elevated above said third discharge opening; means for reciprocating said separating pan in an obliquely upward direction with reference to the plane of said sorting surface; means adjacent said supply side for supplying hulled and uNhulled grain to said separating surface; means for removing said hulled grain from said first discharge opening; means for removing said mixture from said second discharge opening; and means for removing said unhulled grain from said third discharge opening; the improvement wherein said means for removing said unhulled grain comprises: a vibration conveyor integrally mounted at one end thereof to said hulled grain discharge opening, said vibration conveyor being reciprocated by said means for reciprocating said separating pan; a discharge funnel at the other end of said vibration conveyor; said reciprocating vibration conveyor being operative to laterally upwardly transfer said unhulled grain from said unhulled grain discharge opening to said discharge funnel; and hulling means spaced below said discharge funnel to receive and hull said unhulled grain.
Claim 3
Dependent Claim
25 words
A huller as claimed in claim 1 wherein said hulled grain discharge opening is provided with means for laterally and vibratorily transfering the hulled grain.
Claim 4
Dependent Claim
37 words
A huller as claimed in claim 2 wherein: said transfering means includes: a trough containing first and second ends; a stepped delivery surface at said first end; and a straw refuse removal plate at said second end.
Claim 5
Dependent Claim
25 words
A huller as claimed in claim 1 wherein said vibration conveyor has said other end thereof at a higher elevation than said one end thereof.
Claim 6
Dependent Claim
86 words
A huller as claimed in claim 1 further including: a separator hopper pivotally mounted on top of said supply side of said separating pan, and vertically movable responsive to the quantity of the grain charged into said separator hopper; and a grain supply hopper having an opening spaced above said one end of said vibration conveyor and a movable valve over said opening, means for mounting said valve such that said valve will be opened and closed responsive to the vertical movement of said separator hopper.
Claim 7
Dependent Claim
31 words
A huller as claimed in claim 5, further comprising: a deflection means, mounted on said supply side of said separating pan, for laterally dispersing said grain supplied from said separating hopper.
Claim 8
Dependent Claim
17 words
A huller as claimed in claim 1, wherein numerous ventilation openings are provided to said separating pan.
Claim 9
Dependent Claim
21 words
A huller as claimed in claim 1, wherein the separating pan is covered in its entirety with a metallic suction cover.
Claim 10
Dependent Claim
28 words
A huller as claimed in claim 8, wherein: an adjustment bolt for adjusting the inclination of said cover and said attached separating pan is connected to said cover.
Claim 11
Dependent Claim
