摘要:
The invention relates to a separation system for a potato harvesting machine or a preparation machine for separating potatoes, or similar crops, from a mixture of clods, stones, and similar solid bodies. A conveying assembly is thereby utilized to feed the essentially compact mixture as a delivery flow, from where the mixture displaced into the area of at least one drop stage, and thereby influenced by way of a conveying means in the form of an air stream, can be separated. Thereafter, at least the harvested material and the solid bodies, respectively, can be moved on as individual separated goods, and can be moved out of the separation system. The system according to the invention is characterized in that subsequently to the drop stage bringing about a loosening of the mixture, at least one retaining element located opposite the falling separated goods and interacting with the at least one air stream is provided. It is thus achieved in a surprisingly simple way that from there, at least the harvested material and the solid bodies, respectively, can be moved on separately in an essentially opposite conveying direction as sorted individual lots.

A separating device for separating a crop from a mixture with admixtures has a drop stage and a conveying device supplying the mixture in a conveyed stream to the drop stage. An air stream is supplied to the drop stage, wherein the mixture is falling in the drop stage and is affected by the air stream, wherein the drop stage effects loosening of the mixture. A retaining element is arranged downstream of the drop stage so as to face the mixture falling in the drop stage. The air stream interacts with the retaining element. Downstream of the retaining element the crop and solid bodies separated from the mixture are transported farther as separated individual parts in substantially opposite conveying directions. A diverting device is provided that can at least partially divert the conveyed stream upstream of the retaining element.

An improved sorting apparatus for separating loose debris, rocks and clods of dirt from root crops such as potatoes includes a channelizing conveyor, a take-away conveyor having an inlet end positioned below the discharge end of the channelizing conveyor, and a plurality of diverter paddles aligned with the channels of the channelizing conveyor. The channelizing conveyor includes an endless series of segments, each segment comprising a bar having hook portions at the ends thereof and an elastomeric molding formed thereon. Each molding includes several uniformly spaced, wedge-shaped projections, and the projections are longitudinally aligned to form channels for the potatoes, rocks and clods. The segments are interconnected with the hook portions thereof being engaged upon the trailing segment. With such manner of interconnection, as a segment moves from top-dead-center position on the sprockets at the discharge end of the conveyor through an arcuate path corresponding to the tooth pitch of the sprockets, the molding projections rock rearwardly relative to the axis of the bar in its arcuate path of travel.

Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilence are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available.

A crop separating harvester includes a primary crop path having an apex, a forced air supply tangentially positioned to the crop path from a bottom side of the apex, and a crop retrieval member, wherein said crop retrieval member is separated from said apex a predetermined distance defining a gap configured to separate culls from a crop based on a difference in specific gravity between said crop and said culls with respect to said forced air.

A system for sensing loads and varying the dynamics of mechanical devices to accommodate various load weights is disclosed. The system comprises a load receiving device, a load translocator, a load sensing device, and a control unit for processing information sent to it by the load sensing device. The control unit receives and calculates information corresponding to a load weight and varies the speed of a motor and/or hydraulic drive coupled to the mechanical devices translocating the load. This allows for more efficient and consistent load transfers. The system, as described herein, may be applied to several mechanical devices or systems. Specifically as described herein, the system is applied to a conveyor and sorting apparatus which comprises a hopper having a first and a second end, and further comprising a conveyor for transporting the produce from the first end to the second end, a roller bed, coupled to the second end of the hopper. The load sensing device senses and detects a load weight in the hopper and subsequently, through a control system and motor, adjusts the speed of the roller bed and/or conveyor to accommodate a particular load. The apparatus further includes a hopper elevator, coupled to the hopper and the load sensing device, to elevate or lower the first end of the hopper.

An apparatus for providing a fluidized bed to effect the separation of a mixture of articles having at least a first density and a second density that is greater than the first density into separate groups. The apparatus includes an inclined trough which is supplied at an input end with either a fluidization medium, such as sand, or a mixture of articles from which a fluidized bed is formed by forcing gas upwardly through the bottom of the trough and through the fluidization medium or the mixture. In the case where a fluidization medium such as sand is used, the mixture of articles is introduced into the fluidized bed medium so as to be entrained therewith to effect separation as the articles travel in the direction of flow of the fluidized bed medium. Vertical oscillatory movement is imparted to the inclined trough to improve the separation and layering where the mixture of articles is fluidized, or to improve the density uniformity where a fluidization medium such as sand is fluidized as the bed.
