Description

[Detailed Description of the Invention] The clipper-type cutting blades in conventional harvesters were attached to the cutting frame in a series horizontally, and the entire cutting blade was driven back and forth at one location, resulting in extremely large vibrations. . Also, since the culm was fed sideways and then raked backwards with the center of the cutting blade, the culm did not flow well and its posture was disturbed.

The present invention aims to provide a reaping device for a harvester, which generates less vibration due to the operation of the cutting blades and can smoothly scrape the culm backwards. It is characterized in that it is attached to the cutting frame in a V-shape at the rear, and a scraping body is provided above the cutting blades to scrape the culm toward the center.

The embodiment shown in the drawings will be described below. Reference numeral 1 is a threshing device mounted on one side of the machine base of the combine, and the other side of the machine base includes an operation panel, a cockpit, a grain tank, an engine, etc. in order from the front. It's profitable.

Further, in front of the threshing device Wl, a culm conveying device 2 and a reaping device 3 are provided, and the reaping device 3 consists of a weed cutting body 4, a culm pulling body 5, a cutting blade 6, and a pair of left and right raking devices. Wheel 7.7, forming a V-shape with the center at the rear, and front and rear V pulleys 1
It consists of a pair of left and right ear side raking bands 8.8 stretched at 0.10 mm, and a stock raking chain 9 hooked on a sprocket attached to the shaft of one raking wheel 7 at the front. can be,
The culm conveying device 2 includes a stock-end clamping conveyor 11 and a panicle-side conveyor 12.
The handling depth can be adjusted by moving the stock head clamping and conveying body 11 up and down around the horizontal axis 13.

The reaping device 3 is comprised of a pair of left and right clipper blades 14a, 14b in a V-shape with the rear end at the center, and the inner ends of the fixed blades 15 of the clipper blades 14a, +4b are as follows: Reaping frame 1B middle support frame +13
It is attached to the bracket 17 protruding from a, and the outer end is attached to the side frame +
The movable blade 18 is held down by a blade presser screwed onto the support frame 15a of the fixed blade 15, and the arm 2o protruding rearward is a bell crank 2.
1. Rod 22. The left and right movable blades I'll and +9 are reciprocated separately and in opposite directions by a shaft 24 via a crank arm 23.

Further, the shaft 24 is driven by a horizontal shaft having a pulley 25 via a vertical shaft 26, and 2? , 28 is a culm guide.

Next, to explain the operation, the culm to be planted in the field is divided by the weed cutting body 4 as the machine advances, and is also pulled up by the culm pulling body 5, and is pulled up by the left and right clippers 14.
a, 14b.

At this time, the left and right clipper blades 14a and +4b cut both sides of the width of the machine in front of the center, and as they reach the center, they sequentially cut in the rear. As shown in Fig. 6, as shown in Fig. 6, the raking wheel is pivoted on the cutting blade in the transverse direction. The ear side is raked toward the rear center in an orderly manner from the ear side raking bands 8, 8 along the inclinations of the clipper blades 14a, 14b, respectively. Next, the husk culm that has been sent backward by the stock raking check 79 is sent to the threshing device 1 by the culm conveying device 2.

Further, when the cut culm is scraped by the scraping wheels 7, 7 and the panicle side scraping band 8.8, the left and right clipper blades 14a.

Mud and straw debris can get stuck between the central ends of the clipper blades 14a and 14b, but since there is a triangular gap between the central ends of the clipper blades 14a and 14b, mud and straw debris can get stuck together with the culm. Because of the above-mentioned gap, it does not fall and be scraped together with the culm, and in the known method, the ear-side raking band scrapes the upper part of the culm toward the center, and the cutting blade takes a tilted position before cutting. This results in diagonal sorting, which impedes post-processing work such as tilling, and shortens the harvested husk, resulting in shallow handling. However, in this embodiment, the grain is separated almost at the same time as the ear-side raking band 8 rakes. Since the cutting is done, the cutting height is approximately constant.

Further, since the left and right clipper blades 14a and +4b reciprocate in opposite directions, vibrations caused by the reciprocating movement of the movable blades 19 and 19 can be canceled out. When the clipper blade 14a or 14b is worn out, it is only necessary to replace it accordingly.

As described above, the present invention includes a pair of left and right clipper-type cutting blades that are attached to a cutting frame in a V-shape with the center at the rear.
A raking body is installed on the top of these cutting blades to scrape the culm toward the center, so the culm that has been cut as the aircraft advances can be raked in an orderly manner while preventing spillage or disturbance. can.

Also, by driving the left and right cutting blades in opposite directions, vibrations of the cutting device can be reduced.
