Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a pair of left and right lifting screws extending from near the ground to the rear upper blade in a rearward narrowing shape below the top cutter that cuts and removes the treetop head. Concerning the deployed sugarcane harvesting machine.

[Conventional technology]

Conventionally, in the above-mentioned sugar cane harvesting machine, separate hydraulic motors are connected to the rear ends of a pair of left and right lifting screws, and the screws rotate as the machine moves forward to raise the planted sugar cane and remove its top. At the same time, the leaves were guided to a top cutter to be cut and removed, and the leaves were then cut at the base of the plant for subsequent defoliation.
31742).

[Problem that the invention seeks to solve]

However, in order to sufficiently raise the sugarcane stem culm and cut the crown head with the top cutter, the stem culm, which is about to be restored by the left and right screw force in the shape of a rear narrowing, is pressed against the screw. The rear ends of the screws are easily damaged, and if the rear ends of the screws are placed a certain distance apart to reduce damage to the hydraulic motor, etc., the planting position may be affected by damage from typhoons, etc. For bad sugarcane, the stem culm cannot be sufficiently raised, and there is a possibility that the cutting and removal of the top of the cane and the cutting at the base of the plant may not be carried out well.

The purpose of the present invention is to prevent damage to hydraulic motors, etc. while
The purpose is to make it possible to fully grow sugar cane.

[Means for solving problems]

The characteristic configuration of the present invention is that, in the sugar cane harvester at the beginning, a hydraulic motor is connected to the front ends of a pair of left and right pulling screws that are arranged in a narrow shape from near the ground to the rear upper blade below the top cutter. This motor is housed at the back of a fixed divider provided at the front of each screw, and its effects are as follows.

1 [Function] In other words, by disposing a hydraulic motor at the front end of both screws, the rear ends of both screws can be moved to sufficiently raise the planted sugar cane. Moreover, since the hydraulic motor is placed behind the fixed divider, there is little contact with the sugarcane stem culm, and even if it does come into contact, the restoring force is small because the stem culm has not yet been pulled up and deformed. , damage to the hydraulic motor etc. can be sufficiently prevented.

〔Effect of the invention〕

As a result, the oil pressure did not sufficiently prevent Tanabata damage, but it also sufficiently caused sugarcane that was planted in a poor planting position, allowing the treetop head to be cut and removed in an upright position, and the plant base to be cut and removed. A sugar cane harvesting machine that can perform cutting and is excellent in both durability and workability has been created.

〔Example〕

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

Beak number 2
As shown in the figure, the motor vehicle is equipped with a pair of left and right steering front driving wheels (1) and a pair of left and right rear driving wheels (2), with a riding section (3), an engine (4), etc. installed on the top. A sugar cane harvesting vehicle is constructed by connecting and towing a tray 2 (B) equipped with a pair of idle wheels (5) and a dump platform (6) behind the horizontal millet harvester. In the sugar cane harvester (4),
At the front of the machine, there is a top cutter (7), and a pair of left and right lifting screws (8a
) and (8b) are attached to the cylinders (21) and +91 so that they can be raised and lowered, respectively, and the planted sugar cane is separated from the unharvested portion by the side lifter (10) attached to the -force screw (8a). The pedicle culm of is guided into the pedicle culm introduction path (S) by fixed dividers (l1m) and (11b) connected to the front of both screws (8m) and (8b), and both screws (8a) and (ab ) are rotated in opposite directions to transport the top cutter rearward and then raised, and the blade (7a) of the top cutter (7) is rotated to cut and remove the seven tree tops. Both screws (
The rear ends of 8a) and (8b) are placed very close together, and even sugar cane with poor planting posture can be easily planted using both screws (8a).
), (8b) are configured so that the rotation can be sufficiently raised. In addition, hydraulic motors (1B=) and (12b) that drive and rotate both screws (8a) and (8b) separately are attached to the front ends of both screws (8a) and (8b)q, respectively, and both fixed dividers (11a ) and (11b'), and is configured to prevent the hydraulic motors (12a) and (12b) from being damaged by contact with the sugarcane stalk culm when sugarcane is introduced and raised. There is.

Then, the sugar cane, which is pulled up by both screws (8a) and (8b) and falls forward by contact with the push-down rod, is attached to the rear lower blades of both screws (8a) and (8b). The rotary blade (14) is used to cut the stem part, and the spiral body (IF9) attached to the rotary blade is cut.
It is configured to scoop and lift the sugarcane stem culm after cutting. Behind the rotary blade body (14) are a pair of upper and lower delivery rolls (16a) that send out the cut sugarcane stem culm backwards, and (16b) a pair of rolls with claws that transport the leaves of the sugarcane stem culm that are conveyed in the direction of the culm body. The defoliating device side scrapes and separates the sugar cane stalks by high-speed rotation in the direction of the conveying force of the roller (17a), the discharge roll (181) sends out the defoliated sugar cane stalk culms backward, and the discharged sugar cane stalk culms are transferred to the tray. 2 (B) A lifting device (1 turn) that lifts and guides the blade up to the upper blade, and a blower (manufactured by Co., Ltd.) that blows off the defoliated leaves entangled with the stem culm at the terminal end of the lifting device (19), etc. , after defoliating the sugarcane stem culm after cutting) and loading it on Lera IBI [another example] The shape, mounting structure, etc. can be changed as appropriate. Also, the specific configuration of the sugar cane harvesting device can be changed as appropriate, such as providing a pair of left and right crawler running devices in place of the front and rear drive wheels (1) and 2). It is.
