Description

[Detailed Description of the Invention] The present invention involves raising the planted stem culm with 7 taps from side to side, cutting the base of the plant with a cutting blade, and pulling the base end of the harvested stem culm between a pair of upper and lower gripping rolls. The present invention relates to a sugar cane harvesting machine configured to feed sugar cane to a defoliation mechanism.

In general, once cultivated sugar cane is planted and cultivated, it will continue to germinate from the perennial roots even after being harvested, and can be harvested from the same plant every year for several years. They are planted in a straight line at equal intervals, but as the years go by, they grow in different positions, grow densely, or grow sparsely, or in a crooked manner. There was also. When these are harvested with the sugar cane harvester having the above configuration, the sugar cane stem culm stock base raised by the left and right glue lids is cut by the cutting blade and then spreads laterally or vertically, and Sugarcane stem culms in a bent position did not have a fixed orientation, and were not introduced accurately between the gripping rolls of each monoke, resulting in poor introduction and problems that prevented smooth harvesting operations. .

The present invention has been made in view of the above-mentioned circumstances, and reduces the volume of the harvested sugarcane group in the left and right direction, and also corrects the bending of the sugarcane stem culm, thereby preventing the root of the sugarcane from being severed. The purpose is to facilitate the harvesting operation by ensuring the introduction of the sugarcane stem culm into the gripping rolls.

The feature of the present invention is that a pair of left and right inward scraping rotors are provided between the aforesaid cutter and the cutting blade, which act on the raised stem culm over a wide vertical range.The functions and effects thereof are as follows. It is.

In other words, since the stock base of the sugar cane group from the lifter is pressed widely in the vertical width by the inward scraping rotary body, the sugar cane group is compressed inward and the bulk in the left and right direction is reduced, and
If the planting posture is not normal or if the culm is bent, the planting posture and the shape of the culm should be aligned in a substantially straight line so that the culm is bundled. In addition, the inward raking rotary body holds the culm for a while even after the stalk of the sugarcane group has been cut by the cutting blade, thereby preventing the stalk from spreading.
Since the introduction to the gripping roll is done in a stable posture, the cut end of the stem culm does not widen after cutting, and the introduction of the gripping roll is accurate, resulting in smooth harvesting. I am now able to work.

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 and 2, an external force is applied to the driving spiral body +11 that divides the planted sugar cane into objects to be harvested and objects not to be harvested, and the spiral body that raises and conveys the sugar cane to be harvested backwards and upwards. A pair of left and right glues 7ta f2 that are protruded and driven and rotated
1, +21 and a top cutter (3) for cutting and removing the tip of the sugar cane to be harvested is installed on the front part of a crawler type traveling machine body having a driving part (4) and a motion part (5), Prefertilizing lid (a pair of upper and lower wide left and right inward scraping rotors t6 that press and hold the sugar cane groups from 21 and +21 so as to bind them into bundles) e fil
A feed roll (7) which can be driven and rotated, and which pushes the sugar cane culm forward and tilts it forward;
Further, behind the feed roll (7), a cutting blade (8) for cutting the base of the sugar cane is successively disposed on the machine body. A spiral rod (9) is placed above the cutting blade (8) and rotates in synchronization with the cutting blade (8) to lock and lift the base of the cut sugarcane stem culm. Immediately behind the cutting blade (8), a lifting roll (10) is disposed, which lifts the base of the sugarcane stem and culm, similar to the spiral rod (9).

Then, a pair of upper and lower gripping rolls fl11.into which the sugarcane stem culm with its base lifted is introduced. fllll, a defoliation mechanism t121 that defoliates the sugarcane stem culm with a group of clawed rollers while conveying it backwards, and a pair of upper and lower delivery rolls σ3 that clamps the defoliated sugarcane stem culm and forcibly releases it to the rear of the machine. , +13, and the group of vertical lattice rods ti41, which form a gap through which the discharge stalk culm can pass, cantilever diagonally backward, so that when the sugar cane stalk culm passes, the shavings attached or wrapped around the stalk culm are A sugar cane harvesting machine is constructed by combing the sugar cane. Further, a trailer 09 for recovering stem culms is connected to the rear of the machine so that it can be towed.

As shown in Figure 8, a trailer for collecting stem culms (19 is a frame on which a pair of left and right wheels IJ, 61, , ae are supported)
1η, the loading platform has a substantially V-shaped shape when viewed in the front and rear directions (I81 is
It is attached to the front and back axis so that it can swing from side to side, and the loading platform can be moved by swinging the loading platform.
(It has a structure that allows the sugar cane stalks and culms that have been loaded and collected to be released.
