Figure 6 is a top, 'plan view, partly broken away, of the perforated floor of the corn chute; Figure 7 is a fragmentary detailed section, taken on the line l'--! of Figure 1, showing the disposition of the damper in the air passage leading from the cover to the fan; Figure 8 is a sectional view taken substantially on the line 8-8 of Figure 1, Figure 9 is a sectional view taken substantially on the line 9-9 of Figure 8, and Figure 10 is a transverse sectional view taken substantially on the line l0lfl of Figure 8. Referring to the drawings, the numeral I 0 designates generally a corn-'husking machineconstructed according to an embodiment of this invention for attachment between the snapping roll assembly H and the conveyor l2 which conveys the snapped ears of corn to a wagon, not shown in the drawings, or other suitable hopper or storage for the husked corn.
The entire assembly of the snapping roll assembly H, thehusking machine Ill and the conveyor I2 are suitably supported on a mobile; frame I4 having supporting wheels [5 rotatably mounted thereon. The frame II is provided with a suitable drawbar or' drawbar section ii for connection to a tractor or other suitable towing vehicle having a power take-ofi assembly for driving connection to the moving parts of the various sections of thelent-ire assembly or unit ll.
The snapping roll-assembly l I is supported on one side of the frame It and may be of a generally-conventional arrangement extending downwardly and forwardly of the frame H. The" rear end of thesnapping roll assembly is sup ported in a raised positionon the rear end of the frame, and suitable conveyor means t8 are provided in the spaced-apart members IQ for car- 3 ,rying the snapped corn to the upper rear end of the assembly where the ears of corn are suitably deposited to be subsequently huskedand placed in a wagon conventionally assistingthe harvesting of the corn.
The snapped corn conveyor His supported on dropped into the wagon. The conveyor l2 may be of any conventional structure and formation, havin'g thelowerend positioned forwardly on the it has been picked and the time it is placed in 1 the wagon, not shown in the drawings.
The husking machine H1 is formed with an inclined corn chute l8 extending transversely of the frame it between the upper end of the snapping roll assembly Ii and the lower end of the conveyor l2. The
therethrough in a manner and for the purpose to be more particularly described hereinafter. The side walls 20 of the husking machine extend upwardly from the side edges of the bottom wall I9 and are bowed over above the bottom wall to define the top wall or the cover 2| spaced above the perforated bottom wall defining a substantially closed housing having openings at the opposite ends of the bottom wall for receiving cornto be'husked and corn after it has been husked.
A plurality of husking rolls 22 are supported in the chute [8 above the bottom wall l9. The rolls 22 are rotatably jour'naled between a pair of side frame members 24 extending along the length of the bottom wall l9 and spaced thereabove. One end of each of the side frame members 24 is adjustably secured on the frame it for selected adjustment in relation to the bottom wall is. A pair of braces or arms 25 are fixed on one end of the frame M and e tend upwardly adjacent the inner side of the snapping roll assembly II. An outwardly extending arm 26 is fixed n the upper end of each of the side frame members 24 for adjustable engagement with the respective braces 25. The braces 25 are each formed with a plurality of spaced apart apertures 21 for receiving bolts 28' for securing the upper ends of the frame members in a selected position.
The lower ends of the frame members 24 are adjustably supported on the main frame M. A transverse bar 22 is fixed between the lower ends of the frame members opposite ends 29 of which extend outwardly beyond opposite sides of the side bars 24 and are pierced to receive vertical screws 29 which are mounted for rotation in the frame M adjacent the conveyor i2. Lower springs 38 are carried by the frame it encircling relation to the screws 22" beneath'the opposite ends 29 of the bar 28 for cushioning the lower ends of the frame members 26. Upper springs 31 rest on the end extensions 29 and encircle the screws 29' and seated on the upper ends of the springs 3| is a pressure bar 3| carrying adjacent opposite ends internally threaded bushings 29a which threadedly engage the screws 29'. Crank handles 34 are engaged on the upper end of the screw 29' for rotating the screw 29 and thereby vertically adjustingthe pressure bar 3| and thereby moving the lower end of the roller supporting frame members 24 to selected positions against the effort of the springs 32, and 3|.
The husking rolls 22 are positioned transversely of the corn chute l8 for engaging the corn positioned between the rolls 22 and bottom wall l9. Each of the rolls 22 end for engagement has a gear 35 fixed-on one with a similar gear. 35,
4 on an adjacent roll for unitary, timed rotation of all of the rolls. A drive shaft 36 is rotatably carried by the frame It for attachment to a power take-off of a towing tractor or other suitable power means. A sprocket 31 is driven by the shaft 36 and is engaged by a chain or flexible member 38. Another sprocket 39 is fixed on a shaft 40 of one of the husking rolls 22 and also engages the flexible member 38 for rotating the rolls 22 upon rotation of the drive shaft 35.
While the inclination of the corn chute may be .sufificient for moving the snapped ears of corn bottom wall l9 of the chute I8 is perforated to permit the free passage of air.
downwardly by gravity to the unloading conveyor l2, Iemploy a suitable conveyor 4! having transversely extending longitudinally spaced flights 41' moving along the bottom wall l9 below the rolls 22 for moving the ears of corn between the side walls 20. The conveyor ll is driven by a suitable chain or drive connection 42 connected to the driving means 36 for rotating the rolls 22. While the driving means for the corn husking machine is shown in the drawings as including separate drive shaft elements connected together by suitable universal joints, it is understood that a single straight shaft or other conventional driving means may be employed to suit the particular frame on which the device may be mounted.
The chute between the snapping roll assembly H and the discharge conveyor I2 is noted in the drawings as declining and this angle may be changed to a horizontal or upwardly inclined position, the angle being dependent upon the particular corn-huskingmachine ll being used.
The rolls 22 are adapted to engage the corn on the upper side and are rotated in a manner to pull the leaves upwardly between pairs of rollers. For removing the husksfrom the corn chute l8, a vacuum fan or blower 44 is connected to the upper portion of the casing 20;
A suitable fan inlet tubing or conduit 45 is connected to the upper end of thetop wall 2| and communicates with the interior of the chute l8 at one end and the inlet side of the blower M at the other end. A proper discharge conduit or pipe 46 extends from th exhaust side of the blower 44 rearwardly of the frame l4 for discharging the corn husks from the machine ID. as it is pulled through a corn field.
In order to provide for the proper air flow through the husking machine Ill, the rolls 22 are The husking rolls 22 of this machine II] are -disposed in abutting pairs, rotating upwardly at their abutting edges and formed with cutout sections confronting the adjacent roll to permit the free flow of air as effected by the blower 44. All of the hllSkiIlg rolls 22 are formed in the same manner, so a detailed description of one will suitably apply to each of the others.
The husking roll 22 is generally cylindrical in configuration, being made of metal, wood or other I suitable material. One half 48 of the length of the cylindrical roll body A? is formed as a semicylindrical solid body having a plurality of semicylindrical, longitudinally spaced apart members {89 on the other side thereof, as clearly'shown in Figure 3 of the drawings. The spaced apart members 49 are formed with radially arranged spur teeth so. The other end of the cylindrical body: 41 is formed in exactly the same manner as the portiondescribed 'above'w-i-th the solidportion 48% disposed in alignment with the members 49, on the other end. Spaced apart, spur-toothed;
members 50a are formed on the other side of the solid body portion 48a in longitudinal alignment With said body portion 48 of the other end of the same roll.
As the rolls 22 are disposed in pairs, each pair of rolls 22 are positioned and timed in rotation, whereby the spaced spur members of one roll will confront the spaced spur members of the other roll during the timed rotation, and the solid body portions will abut. The spur members of one roll of each pair are transversely aligned with the spur members of the abutting, confronting roll, so that the confronting spur teeth will engage at their tips durin the operation of the machine and the spaces between the spur members will provide for the free flow of air upwardly throughthe apertured bottom wall l9, between the husking rolls, through the conduit 45, the blower 44 and out the discharge conduit 46.
A pulley or sprocket 5| is rotated by the drive shaft 36 and engages a belt 52. The belt 52 is also trained about the pulley 54 which is fixed on the rotatable shaft 55 which carries the fan blades.
In order to prevent the blower 44 from discharging light corn from the machine l1 along with the corn husks, a suitable damper 56 is rockably mounted in the blower inlet conduit 45. A suitable adjusting crank or screw 5! is engaged through the conduit 45 and is connected to the damper for varying the size of the opening through the conduit.
In the use and operation of the corn-husking machine II, the snappin roll II and conveyor 12 may be driven or actuated in any conventional manner. As the ears of corn are moved down the corn chute [8 between the husking rolls 22 and the apertured wall IS, the rolls will strip the husks from the corn and the suction in the corn chute l8 will discharge the husks out through the discharge port or conduit 46.
The shakers, shaker screens and shell corn augers in use on conventional styles of husking beds currently in use are dispensed with in the structure, use and operation of this machine, as such elements are not required.
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the I appended claims.
I claim:
