Description

[Detailed description of the invention]

[Industrial Application Field 1] The present invention relates to a harvester for harvesting potatoes, beets, and other potatoes. [Prior Art] Most conventionally known potato harvesting machines have an outer rod conveyor and an inner rod conveyor arranged in two stages, upper and lower, behind the digging blade.

[), the distance between the rods on the outer conveyor is made coarser, and the distance between the rods on the inner conveyor is made finer, in order to improve separation of potatoes from leaves, weeds, soil, etc., but this has the problem of complicating the mechanism. there were. In order to solve the above problem, the potatoes, stems, leaves, etc. dug up by the digging blade are placed on the rear part of the digging blade, and the rods are spaced apart enough to allow the mud adhering to the potatoes, etc. to fall. A feed conveyor V (2) is provided, and a horizontal conveyor is located at the conveyance end of this vertical conveyor and moves in a direction perpendicular to the vertical conveyor. By installing a sorting and turning roller diagonally that rotates in the same direction as the movement direction of the upper surface of the horizontal conveyor, separates the potatoes from the stems and leaves, and avoids changing the direction of the potatoes, the vertical conveyor is configured as a series. A simplified and lightweight device is described in, for example, Japanese Utility Model Publication No. 55-3769 (FIG. 2). In this case, the mist, stems, leaves, etc. conveyed by the vertical conveyor are transferred to the horizontal conveyor V.
Since the conveyor is carried out near one side edge, it is conveyed concentrated near one side edge of the traversal conveyor and is likely to fall. Therefore, the sorting performance of the sorting deflection roller for foliage and weeds deteriorates, and the The potatoes that were raised by the lifting device were mixed with stems and leaves, and there was some melting that required re-sorting. [Problems to be Solved by the Invention] Therefore, the present invention conveys the potatoes, stems, leaves, etc. discharged by the vertical conveyor f'sr, using the entire width of the horizontal conveyor, and The purpose of the present invention is to provide a potato harvesting machine that improves sorting performance by widening the field and prevents stems and leaves from being mixed into the potatoes being turned.

[Means to solve the problem]

In order to achieve this object, the present invention is characterized in that the conveyance end portion of the vertical conveyor extends to a position above the widthwise substantially intermediate portion of the horizontal conveyor.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to FIG. 11! In the figure, reference numeral 1 denotes a digging blade of a potato harvester (Bote 1 to Harvester), and behind this digging blade 1, a first vertical feed Rondo competition X72 is arranged. This first rod conveyor 2 is inclined such that the digging blade 1 side is low and gradually becomes higher toward the rear, and the conveyance starting end side is movable up and down together with the digging blade 1 with the conveyance terminal end 2a side as an axis. The distance between the tubes is such that the potatoes, stems and leaves (including weeds) placed on the competition V and conveyed do not fall, but the mud adhering to the potatoes, etc., falls. Below the conveyance end portion 2a of the first round conveyor V2,
Weeding [1-ra 3] rotating in the opposite direction is provided,
Below this weeding roller 3, a second vertical feed rod conveyor 4 rotates in the same direction as the first rod conveyor 2, and has approximately the same pitch and inclination angle as the first rod conveyor 2. It is arranged with Further, below the conveyance end portion 4a (rotating portion) of the second rod conveyor 4, a separation roller 5 that rotates in a direction opposite to the rotational direction of the conveyance end portion 4a (both indicated by arrows) is supported by a shaft. and is forcibly driven via a transmission system (not shown). Immediately after this separation port 55, a lubricating synthetic wood polisher 6 is mounted along the conveying lower surface of the second rod conveyor 4 on its return stroke, with its front end pivoted and its rear end locked with a stopper. The length extends to the outside of the widthwise end of the cross-feeding rod conveyor 7, which will be described later. A traverse conveyor 7 is provided substantially horizontally in a direction perpendicular to the second rod conveyor 4 below the conveyance end portion 4a of the second rod conveyor 4 and the separation roller 5. The rollers 5 extend to approximately the middle position in the width direction of the traverse rod conveyor X'77. A sorting direction changing roller 8 is obliquely installed on the upper side of the conveyance terminal end of the cross-feeding rod conveyor 7. The sorting direction changing roller 8 rotates, for example, in the direction of the arrow in the top view, that is, in the direction of movement of the upper surface of the cross-feeding rondo competition 177 and in the direction 1751, and the leaves and foliage conveyed by the conveyor 7 are rotated in the direction of the arrow in the top view. The potatoes are separated from the potatoes by being sandwiched between the upper surface and the rollers 8, and are released into the field from the conveyor end of the conveyor 7 through the underside of the roller 8. It is designed to be directed and sent to a lifting device (not shown). In such a configuration, the potatoes, stems, leaves (including weeds), etc. that are dug up by the digging blade 1 are placed on the first vertical feed rod conveyor 2 and conveyed, and are not attached to the potatoes, etc. The muddy soil is dropped, and the conveying end portion 2a and the weeding roller 3 are
Leaves, weeds, etc. are rolled up between the conveyor belt and removed, and the remaining stems, leaves, etc. are sent out to the second vertical feed rod conveyor side. This second conveyor 4 also transports the soil while dropping it, and among the potatoes, leaves, etc. sent out from the transport terminal end, the stalks, leaves, etc. are sandwiched between the transport terminal end 4a and the separation roller 5. It is sent along the lower surface (return stroke) of the conveyor 4, and is discharged to the field from its terminal end f)sr while sliding on the synthetic resin plate 6. Therefore, mainly the potatoes fall from approximately the middle position in the width direction of the cross-feeding rod conveyor 7 with a suitable drop, so the potatoes, stems, leaves, etc. fall in the width direction of the cross-feed rod conveyor 1. The entire conveying surface is effectively used, and the sorting direction roller 8 is almost evenly distributed (as it is, the sorting direction [1-ra 8] ensures the sorting of stems, leaves, etc.). The potatoes are delivered to the field from the feeding end of the conveyor 1 to the field, and the potatoes are turned and sent to the lifting device without any stems or leaves getting mixed in. [Effects of the Invention] As explained above, According to the potato harvesting machine according to the present invention, the conveyance end portion of the vertical feed rod conveyor is moved horizontally [1
Since it extends above the approximately half-way point in the width direction of the rod conveyor, the potatoes and stems and leaves discharged from the vertical rod conveyor ψ are conveyed spread over almost the entire width of the horizontal rod conveyor, and are sorted and redirected by the sorting and redirection rollers. Because it is done,
Separation and sorting of stems and leaves is performed reliably, and the stems and leaves do not mix with the potatoes to be turned. In addition, the vertical feed rod conveyor is single-layered, so the structure is simple and a small and lightweight harvesting machine can be constructed.
