Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a stem and leaf sorting device for a harvester that harvests potatoes such as potatoes and Bee 1.

[Advantageous technology]

Many of the well-known potato harvesters have an outer rod conveyor and an inner rod conveyor arranged in two stages, upper and lower, behind the digging blade, with the rods of the outer conveyor being roughly spaced, and the inner conveyor finer the rod spacing,
Although efforts are being made to ensure good separation of potatoes from leaves, stems, weeds, and soil, there is a problem in that the mechanism becomes complicated. In order to solve the above problem, the potatoes, stems, leaves, etc. dug up by the digging blade are placed behind the digging blade, and the rods are spaced apart enough to allow the mud adhering to the potatoes, etc. to fall. For example, Jikosho's system has a conveyor and a sorting roller located at the end of the conveyor and rotating in a direction opposite to the conveyor to improve the sorting performance of stems, leaves, etc. and simplify the mechanism. It is described in No. 55-9076. In this prior art, the foliage, etc. that have been sorted by the conveyor and the sorting roller are sent to the next conveyor without being reliably discharged outside the machine, and the next conveyor must separate the potatoes from the foliage, etc. There was a problem.

[Problems to be solved by the invention]

The present invention has been developed in view of the above circumstances, and is designed to reliably discharge the leaves, weeds, etc. selected at the m-feeding end of the conveyor into the field without discharging them onto the next conveyor.
The present invention aims to provide a stalk i-sorting field for a potato harvester that improves the sorting performance and simplifies and reduces the weight of the WJ method.

[Means for Solving the Problem 1] In order to achieve this object, the present invention places potatoes, stems, leaves, etc. that have been dug up by the digging blade behind the digging blade, and places the potatoes, etc. An endless conveyor with a spacing between rods large enough to avoid falling mud is placed below the rotating section at the end of the conveyor and rotates in a direction opposite to the direction of rotation of the rotating section at the end of the conveyor. The present invention is characterized in that a lubricating plate is disposed along the lower surface of the conveyor immediately after the separation rollers between the separation ports and the separation rollers. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 is a digging blade of a potato harvester (Bote 1 to Harvester), and behind this digging blade 1, a first vertical feed rod conveyor 2 is installed. This first rod conveyor iy2 has a low digging blade 1 side,
It is inclined so that it gradually becomes higher toward the rear, and the conveyance start end side can move up and down with the digging blade 1 with the conveyance terminal end 2a side as an axis, and the interval between the rods is determined by the digging blade 1. The potatoes are placed on the container 97 and transported,
Leaves (including weeds) do not fall, only the muddy soil attached to potatoes etc. falls. lll1 which is the rotating part of the first lot conveyor 2! A weeding roller 3 that rotates in the opposite direction is stacked below the feed end portion 2a, and a second vertical feeding rod conveyor ψ4 is connected to the first lot conveyor 2 below this weeding roller. It rotates in the same direction and is disposed with substantially the same rod spacing and inclined angle claws as the first rod conveyor 2. Further, below the conveyance end portion 4a (rotating portion) of the second conveyor 4, there is a separation roller 5 which rotates in a direction opposite to the rotational direction of the conveyance end portion 4a as indicated by the arrow. is pivotally supported and forcibly driven via a transmission system (not shown).
It's becoming a sea urchin. Immediately after this separation roller :), a second
A lubricating synthetic resin layer 6 is disposed along the lower conveying surface of the lot conveyor 4 in its return stroke, with its front end pivoted and its rear end locked with a stopper. It extends to the outside of the widthwise side end portion of the feed rod conveyor 7. A cross-feeding conveyor 7 is provided substantially horizontally in a direction perpendicular to the second lot conveyor 4 below the conveyance end portion 4a of the second lot conveyor 4 and the separation roller 5. The separation roller j) extends to approximately the middle position in the width direction of the traverse rod conveyor 7. A direction changing/sorting roller 8 is disposed on the upper side of the conveyance terminal end of the traversing rod conveyor 1. It should be noted that an unillustrated unloading device is provided at the discharge position of the potatoes from the cross-feeding rod conveyor 7, where the direction is changed by the direction changing/sorting roller, and the sea urchins are conveyed to the storage side. In such a configuration, the material to be dug by the digging blade 1,
While the stems, leaves (including weeds), etc. are placed on the first vertical feed rod conveyor 2 and conveyed, the mud adhering to the potatoes, etc. is dropped, and the leaves are transported between the conveyance end 2a and the weeding roller 3. Stems, leaves, weeds, etc. are rolled up and removed, and the remaining stems, leaves, etc. are sent out to a second vertical feeding rod conveyor 4. This second
The second conveyor 4 also transports the soil while falling, and the potatoes, leaves, etc. sent out from the conveyance end are sandwiched between the conveyance end 4a and the sorting roll 5, and then transferred to the second conveyor. K) on the lower surface of conveyance (return stroke) of 4)
-), and while sliding on the synthetic resin &6, it is fed by the rod on the return stroke of the second conveyor 4, and is discharged from the end of the synthetic resin conveyor 6 into the field. Then, the potatoes are mainly discharged from the conveyance end of the second rod conveyor V4 onto the transverse feed lot conveyor 7.
By effectively using the width of the transverse conveyor 7, the potatoes are diverted by a deflection/sorting roller 8 toward sorting of stems, leaves, etc., and sent upward by a lowering device. =6-

[Effect of invention in Song Dynasty]

As explained above, the potato harvesting machine of the present invention has I'
According to the stem and leaf sorting device, potatoes, stems, leaves, etc. are sorted at the end of the conveyance of a rod conveyor that conveys the stems, leaves, etc.
Weeds are sorted out, and the leaves, weeds, etc. are forcibly discharged by the return stroke of the =I conveyor and the lubricating synthetic resin plate. Even if it is avoided to reach the middle of the direction, the stems, leaves, etc. can be discharged to the field without being disturbed by the horizontal conveyor. In addition, the mechanism for sorting out stems, leaves, weeds, etc. is simplified, so
It is possible to improve the working rate and reduce the weight of the entire harvester.

Claims (1)

[Claims] Behind the digging blade, an endless conveyor is installed, which places the potatoes, stems, leaves, etc. that have been dug up by the digging blade, and has a distance between rods that is large enough to drop the mud adhering to the potatoes, etc. A separation roller is provided below the end rotating section and rotates in a direction opposite to the rotational direction of the conveyance end rotating section. Immediately after this separation roller, a lubricating plate is installed along the lower surface of the conveyor.
