Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates primarily to a harvester for harvesting green cane, that is, sugar cane with green leaves and subjecting it to predetermined processing.

BACKGROUND TECHNOLOGY Conventionally, a technique is known in which sugar cane is harvested from a work site, defoliated and cut, and then sorted using wind power and loaded onto a companion vehicle or the like.

For example, in a conventional work machine for harvesting sugarcane, the roots of the sugarcane are harvested, the leaves are removed, and then shredded, and a suction type fan is used to vacuum up light debris such as dead leaves in the middle of the conveyor belt. Air was being blown to the side of the work equipment. Special Publication No. 49-26339 is
In a sugarcane reaper, there is a belt conveyor that transports the sugarcane from the shredding device, two shredding drums with blades on the periphery, a belt conveyor that transports the shredded material backwards, and pieces and straw of the cut sugarcane, and other unnecessary parts. A rotary deflection device that changes the falling angle of the object, a blower that blows off the cuttings, straw, and other unnecessary materials when the sugarcane cuts fall, and a discharge port that discharges the cuttings, straw, and other unnecessary materials blown away by the blower. discloses a sugar cane reaper with a loading belt conveyor which can be folded in the middle and has a deflection plate at the end.

In addition, the sugarcane harvester disclosed in Japanese Patent Application Laid-open No. 55-48318 has a crop lifter for pulling down the stem, a tatsupa for cutting off the top of the treetop, a base cutter for cutting the root trunk, and a vine that moves the cut sugarcane backward. A pair of rollers for conveying, a lever for pushing the conveyed sugarcane into a vertical position with the root at the top, a roll with a chain with one end free for removing large trash from the sugarcane in the vertical position, and cutting the sugarcane. A belt conveyor that receives and conveys the cut sugar cane, a blower that blows away light trash when the cut sugar cane collides with the buffer member and falls, and the rear of the trash machine. It is equipped with a trash guide plate that discharges waste.

Problems to be Solved by the Invention However, in conventional sugarcane cutting machines, light trash such as dead leaves is sorted by suction into a suction fan when being conveyed by a belt or chain conveyor.
There was a drawback that it was not possible to completely remove light debris such as dead leaves.

Moreover, it is unavoidable that light trash such as dead leaves may clog the conveyance path of the fan or conveyor.

Furthermore, since a belt or chain conveyor was simply used, it was difficult to prevent mud from adhering to or getting mixed into the storage container.

This invention has been made in view of the prior art as described above, and particularly aims to provide a harvester that can minimize the amount of dead leaves and soil mixed in.

Means for Solving the Problems In order to achieve the above-mentioned objects, the present invention includes a sugarcane cutting device 3 and a rotary conveyor 1 in which a plurality of rings are arranged in a drainboard shape with a gap large enough to allow small pieces of soil to pass through.
5, which are provided at predetermined intervals inside the ring of the rotary conveyor 15, and rotatably convey the cut sugar cane cut and cut by the sugar cane cutting device 3 and conveyed to the inner lower part of the rotary conveyor 15 to the inner upper part. a belt conveyor 18 having a starting end penetrating the inside of the rotary conveyor 15 and arranged to be inclined upward from the starting end toward the terminal end; "H" is placed on both sides of the starting end of the belt conveyor 18 to guide the cut sugar cane as it falls from the upper part toward the starting end of the belt conveyor 18.
When the chute 19, which is installed in the opposite direction, and the cut sugar cane fall from the inner upper part of the rotary conveyor 15 toward the starting end of the belt conveyor 18, light trash such as dry leaves among the cut sugar cane is removed. The first blower 20 blows away
and a guide 21 that guides the trash blown by the first blower 20 to the side of the harvester.
A second blower 23 that blows away light trash such as dead leaves among the cut products in a desired direction when the cut sugar cane falls from the end of the belt conveyor 18; and a work table 2 disposed in the middle of the belt conveyor 18.
7, and a harvester equipped with.

Effects of the Invention With the above configuration, the present invention has the following effects.

In the present invention, by arranging a rotary conveyor in which a plurality of rings are arranged in a drainboard-like manner with gaps between them, it is possible to drop small pieces of soil when receiving cut sugar cane at the lower part of the rotary conveyor. Blades arranged at predetermined intervals inside the conveyor allow the sugar cane cuts to be rotated and conveyed to the upper part of the rotary conveyor. When the cut sugar cane falls from the blade, the blowing action of the first blower causes a difference in the falling angle between the cut sugar cane and light trash such as dead leaves, and the cut sugar cane and light trash such as dead leaves are dispersed. be able to. By arranging the guide, light trash such as dead leaves blown by the first blower can be blown away to the right or left. By arranging the chute on both sides of the starting end of the belt conveyor in an inverted "V" shape, cut sugar cane falling from the upper part of the rotary conveyor can be reliably received by the chute and the starting end of the belt conveyor. . By arranging a workbench in the middle of the belt conveyor, an operator can stand on the workbench and monitor the conveyance of cut sugarcane products, and selectively remove only the tops of the sugarcane as necessary. By combining a rotary conveyor and a belt conveyor, two blowers can be properly combined and arranged without increasing the overall size of the harvester. The second blower can blow away light trash such as dead leaves in a desired direction.
