Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a reaping device that cuts the stock side of sugar cane, a conveying device that changes the posture of the harvested sugar cane to a collapsed position facing the longitudinal direction of the machine body, and transports the sugar cane toward the culm. The present invention also relates to a sugar cane harvester equipped with a defoliation device for scraping leaves from conveyed sugar cane.

Since the sugar cane harvester described above removes leaves without shredding the stem, the cut end surface is less exposed to air than the sugar cane harvester which shreds the stem and removes leaves. When the cut end surface is exposed to air, the sugar content is less likely to be oxidized and become invert sugar, which has the advantage of suppressing a decrease in yield.

However, although the above-mentioned harvester defoliates the sugarcane, the leaves after defoliation stick to the sugarcane and are not separated, and if the harvester is to be collected after being released into the field, the leaves must be removed at the time of collection. There was a drawback that the efficiency of post-processing work was lowered, such as having to separate it again, which required time and effort.

Therefore, as a means to solve the above-mentioned drawbacks, there is a technique disclosed in Japanese Patent Publication No. 52-23946.

With this structure, there is a guide wire drum placed above the discharge conveyor located behind the defoliation device to send the defoliated sugar cane to the discharge conveyor, and a guide wire drum that rotates in the opposite direction to the guide wire drum. a reversing wire drum is provided, the guide wire drum and the reversing wire drum cooperate to separate the stalks and leaves of sugar cane, and the separated leaves are lifted upward by the wire drum and sent to the blower. Therefore, it is configured to be released outside the aircraft.

However, with a structure that uses wire drums like this, the wire drums overlap, making it difficult to lift the separated leaves upwards and out of the stem conveyance path. The drawback is that leaves tend to accumulate in the triangular space formed by the wire drum and the discharge conveyor, that is, the dead space, and the wire drum becomes unable to rotate due to clogging, resulting in a decrease in work efficiency. .

An object of the present invention is to enable separation of stems and leaves after defoliation treatment without reducing work efficiency.

The characteristic configuration of the present invention for achieving the above object is to dam up the leaves from the sugar cane after defoliation treatment in the middle of the conveyance path of the conveyance device and on the downstream side of the defoliation device in the conveyance direction. A large number of rods for separating the stems and leaves were installed on the rear side of the fuselage, with the longitudinal direction along the longitudinal direction of the fuselage, and with sufficient spacing to allow the sugar cane stalks to pass in the width direction of the fuselage. The rods are arranged side by side in a diagonal position, and a scraping roller is installed at the lower end of the rod to scrape off the leaves after defoliation that have been blocked by the rods to the outside of the machine below. ,
A blower is provided facing the upper part of the rod for blowing off the leaves that have moved upward along the rod to the outside of the machine, and this configuration provides the following effects.

That is, when the sugar cane after the defoliation process passes through the rod in the backward position, only the rod-shaped stem is conveyed, and the leaves attached thereto are caught by the rod and removed. The leaves mixed in the sugar cane and the leaves blocked by the rod are scraped downward by a scraping roller provided at the lower end of the rod, and are scraped upward along the slope of the rod. The leaves that move are ejected out of the machine by a blower. This prevents the rod, which serves as a separation device after defoliation, from clogging with leaves, and allows reaping work to be performed without reducing work efficiency. Since the amount of upward lifting of the separated leaves is small, the wind force of the blower can be reduced, which has the advantage of making the blower more compact and, by extension, the engine smaller.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
