Abstract

Abstract A machine for harvesting a crop item such as a cabbage having a relatively large head located above ground and a stem-root combination connected to said head including a stem merging into an elongated root, comprising a frame, a connection for mounting the frame on a tractor, a snout at the leading end of the frame having an entry portion for receiving the stem, a conveyor comprising a pair of substantially parallel screws of opposite pitch leading upwardly away from said entry portion, means for rotating said screws in opposite directions to engage said stem and move said crop item upwardly along said conveyor, a pair of spaced rails underlying the head for guiding said head in its movement along said conveyor, stabilizing rails below said screws for engaging said stem-root combination to stabilize said crop item during its movement along said conveyor, and a cutter mounted on said frame remote from said snout for severing said stem from said head proximate said head when it reaches the end of movement on the conveyor.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 136 words
A machine for harvesting a crop item having a head located above ground and a stem connected to said head and merging into an elongated root located below ground comprising a frame, lifting means on said frame located in contiguous relationship to the ground for lifting said crop item from the ground, conveyor means positioned in underlying relationship to said lifted head with an entry portion proximate said lifting means for engaging said stem and conveying said crop item away from said lifting means with said head positioned above said conveyor means, stabilizing means located below said conveyor means for engaging said root to stabilize said crop item while it is being conveyed by said conveyor means, and head-supporting means located above said conveyor means for supporting said head as it travels along said conveyor means.
Claim 2
Dependent Claim 136 words
A machine for harvesting a crop item having a head located above ground and a stem connected to said head and merging into an elongated root located below ground comprising a frame, lifting means on said frame located in contiguous relationship to the ground for lifting said crop item from the ground, conveyor means positioned in underlying relationship to said lifted head with an entry portion proximate said lifting means for engaging said stem and conveying said crop item away from said lifting means with said head positioned above said conveyor means, stabilizing means located below said conveyor means for engaging said root to stabilize said crop item while it is being conveyed by said conveyor means, and head-supporting means located above said conveyor means for supporting said head as it travels along said conveyor means.
Claim 3
Dependent Claim 25 words
A machine as set forth in claim 1 wherein said stabilizing means comprise a pair of elongated rail means for receiving said elongated root therebetween.
Claim 4
Dependent Claim 19 words
A machine as set forth in claim 2 including means for biasing said elongated rail means toward each other.
Claim 5
Dependent Claim 25 words
A machine as set forth in claim 2 wherein said conveyor means comprise elongated substantially parallel screw means of opposite pitch for engaging said stem.
Claim 6
Dependent Claim 24 words
A machine as set forth in claim 4 wherein said parallel screw means and said elongated rail means extend substantially parallel to each other.
Claim 7
Dependent Claim 27 words
A machine as set forth in claim 1 wherein said head-supporting means comprise a pair of spaced elongated rail means for engaging the underside of said head.
Claim 8
Dependent Claim 31 words
A machine as set forth in claim 6 including means for driving said screw means in opposite directions so as to pull said head downwardly on said spaced elongated rail means.
Claim 9
Dependent Claim 21 words
A machine as set forth in claim 7 wherein said stabilizing means comprise a second pair of spaced elongated rail means.
Claim 10
Dependent Claim 207 words
A machine for harvesting a crop item having a head located above ground and a stem connected to said head and merging into an elongated root, comprising a frame, lifting means located in contiguous relationship to the ground for lifting said crop item from the ground, elongated conveyor means for conveying said crop item away from said lifting means, head-engaging means located above said conveyor means and extending substantially throughout the length of said conveyor means for engaging said head and guiding said head during its travel with said conveyor means, said head-engaging means comprising a pair of spaced elongated rod-like rail means for engaging the underside of said head, said elongated conveyor means comprising screw means of opposite pitch including thread means extending outwardly from base means, and means for rotating said screw means in opposite directions so as to cause adjacent portions of said base means to engage opposite sides of said stem and pull said head downwardly on said spaced elongated rail means, said screw means and said rail means extending substantially parallel to each other, and said rail means being laterally outwardly spaced from said adjacent portions of said base means of said screw means which are in actual engagement with said stem.
Claim 11
Dependent Claim 207 words
A machine for harvesting a crop item having a head located above ground and a stem connected to said head and merging into an elongated root, comprising a frame, lifting means located in contiguous relationship to the ground for lifting said crop item from the ground, elongated conveyor means for conveying said crop item away from said lifting means, head-engaging means located above said conveyor means and extending substantially throughout the length of said conveyor means for engaging said head and guiding said head during its travel with said conveyor means, said head-engaging means comprising a pair of spaced elongated rod-like rail means for engaging the underside of said head, said elongated conveyor means comprising screw means of opposite pitch including thread means extending outwardly from base means, and means for rotating said screw means in opposite directions so as to cause adjacent portions of said base means to engage opposite sides of said stem and pull said head downwardly on said spaced elongated rail means, said screw means and said rail means extending substantially parallel to each other, and said rail means being laterally outwardly spaced from said adjacent portions of said base means of said screw means which are in actual engagement with said stem.
