A crop drier has an enclosed drying chamber with an entrance at the front thereof and an exit adjacent the back thereof. A conveyor system includes a floor conveyor for receiving long stemmed crop and conveying it to a lifting conveyor which drops the crop on a lower transverse conveyor at the rear of the chamber. The lifting conveyor is configured as a right angled triangle that lifts and drops crop on an elevator conveyor at one side of the chamber. The latter conveyor then moves the crop to an upper transverse conveyor at the top of the chamber near the front thereof. The upper conveyor is structured to reciprocate within the chamber across its width while continuously receiving crop from the elevator conveyor. The upper conveyor has an endless chain with an upper and a lower run and while an endless belt is moving and dropping crop to the floor conveyor a reversing mechanism is cycled to reciprocate the upper conveyor, or a surface associated with the conveyor, and ensure that the crop is distributed uniformly across the entire width of the chamber. A safety cut off device is mounted adjacent the juncture of the elevator and lower transverse conveyors to stop the latter's movement and that of the floor conveyor is an excess of crop is loaded on the elevator conveyor. A blower and heating plant are connected by ducts to the chamber and once the crop has been dried satisfactorily, the crop can be directed by the upper conveyor to a branch duct via a funnel so that the blower can then move the dried crop to a collection area.
A crop drier comprising a substantially enclosed drying chamber having an entrance, an exit and means for supplying heat to said chamber, a conveyor system comprising means in said chamber for moving crop in a first direction for moving crop along the length of said chamber and from said entrance to said exit, said system including movable conveyor means supported adjacent said entrance of said chamber, said conveyor said means being movable in a second direction transverse to said first direction relative to the width of said chamber at least in part within and in part outside said chamber proximate said entrance and being positioned to receive crop from another conveyor which is provided in said system substantially out of and along the side of said chamber to carry crop from said exit to said conveyor means, driving means connected to said conveyor means to move same in a horizontal reciprocating movement transverse to said first direction and deposit crop therefrom uniformly throughout substantially the entire width of said chamber.
A crop drier comprising an elongated drying chamber having an entrance and an exit for crop, a conveyor system for moving crop along the length of said chamber from said entrance to said exit, said system including a floor conveyor and a discharge mechanism for moving crop out of said chamber and to an upper transverse conveyor assembly provided at the side of said entrance adjacent the upper side of said chamber, a support structure included in said assembly mounted therein adapted for reciprocal movement across substantially the width of said chamber in directions tranverse to the direction of movement of said floor conveyor, said assembly including endless belt means on said supporting structure, driving means connected to said supporting structure and said belt means adapted to move each of same, crop received by said assembly being carried and moved by said belt means and being deposited thereby within and across the width of said chamber.
A crop drier comprising an elongated drying chamber having an entrance and an exit for crop at the shorter ends thereof, a conveyor system for moving crop along the length of said chamber from said entrance to said exit, said system including a floor conveyor, an upper transverse conveyor assembly and a further conveyor for moving crop above said floor conveyor to said upper transverse conveyor assembly, a portion of said assembly being mounted for reciprocal movement within said chamber in a horizontal direction substantially perpendicular to the direction of movement of said floor conveyor, said portion including endless belt means, driving means connected to said portion and to said belt means to move each of same, whereby crop received by said assembly is moved by said reciprocating belt means and deposited within said chamber across the width of same, control means connected to said assembly to disconnect said driving means from said portion and prevent reciprocal movement of same, said control means being connected to reverse the direction of movement of said belt means for discharging crop from the drier.
A crop drier comprising a drying chamber having an entrance, an exit and means for supplying heat to said chamber, a conveyor system for moving crop along the length of said chamber and from said entrance to said exit, said system including movable conveyor means supported adjacent one end of said chamber, said conveyor means being movable relative to the width of said chamber and being positioned to receive crop from another conveyor of said system, driving means connected to said conveyor means to move same and deposit crop uniformly throughout substantially the entire width of said chamber, said conveyor means being located ajdacent the upper side of said chamber and comprising an upper conveyor which is displaceably mounted relative to said chamber for reciprocating movements across the width of said chamber, said upper conveyor being an endless conveyor having an effective run in the smae general direction in which said upper conveyor is reciprocable, said upper conveyor being mounted on supporting structure which is movable horizontally relative to at least one guide member on said conveyor means, a transmission mechanism of said driving means being connected to said supporting structure to move same relative to said guide member, said transmission mechanism including a movable endless member, one part of said endless member being fixed with respect to a portion of said guide member, said one part of said endless member being linked to said guide member portion between the connection of the upper and lower runs of said endless member and the reciprocal movements of said upper conveyor being synchronized so that said connection moves from one run of said endless member to the other said run.
A crop drier comprising a drying chamber having an entrance, an exit and means for supplying heat to said chamber, a conveyor system for moving crop along the length of said chamber and from said entrance to said exit, said system including movable conveyor means supported adjacent one end of said chamber, said conveyor means being movable relative to the width of said chamber and being positioned to receive crop from another conveyor of said system, driving means connected to said conveyor means to move same and deposit crop uniformly throughout substantially the entire width of said chamber, said conveyor means including an upper conveyor which has endless belt means, a portion of said conveyor means being reciprocable in a direction transverse to the length of said chamber, said driving means including an endless chain which is connected to said portion of said conveyor means to reciprocate same back and forth, said conveyor system comprising an endless floor conveyor at the bottom of said chamber, said floor conveyor being arranged to feed crop within said chamber to a discharge mechanism located adjacent the rearend of said chamber, said discharge mechanism being positioned to feed crop out of said exit, said discharge mechanism comprising a lifting conveyor, one run of which is inclined to the vertical, said lifting conveyor, when viewed in side elevational, being substantially right-angled triangular configuration, an upper run of said lifting conveyor forming the figurative adjacent side of said triangle.
