Description

[Detailed description of the invention] The present invention relates to a combine harvester for threshing cut husk,
It is an object of the present invention to effectively suppress the blowing out of threshing from the head side of the threshed husk culm supply port of a threshing device.

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

In the figure, 6 is a pulling device that engages with the base of the planted culm near the ground in front of the clipper-type reaping device 7 and pulls it up and conveys it diagonally upward to the rear of the machine, and 4 is in the standing position. Alternatively, a tip locking method that locks the tip of a culm harvested in a substantially upright position and conveys it to a partially arc-shaped entrance guide plate 3 connected to the threshed culm supply port 2 of the threshing device 1. A stock gripping and conveying device 4B that clamps the stock end of the harvested culm and transports it to one person in the feed chain of the threshing device 1 in cooperation with the transport device section 4A and the stock head section 4A of the harvested culm. A cut husk culm conveying device comprising: a plate-metal cover that covers a conveying end portion 4a of the ear tip locking conveying device section 4A on a portion of the threshing wall 1a located above the threshed culm supply port 2; 5 is pivotally connected via a hinge 8 so as to be able to swing open and close between a horizontally protruding state toward the front of the fuselage and a state in which it is pivoted upward and retracted toward the rear of the fuselage. is provided with a hanging membrane 5a made of an elastic material, and on the head side of the entrance guide plate 3 near the threshed husk culm supply port 2, straw waste and rice husk generated during the threshing process are provided. A blowout prevention plate 10 that prevents dust from being blown out from the threshing culm supply port 2 to the outside of the handling room 9 is mounted on a fixed member so as to be swingable in the longitudinal direction of the machine. The blow-out prevention plate 10 is formed to be able to swing backwards centering on the tip side of the supply port 2 by abutment of the tip portion, and is configured to allow passage of the culm to the supply port 2.

In summary, the present invention includes a blow-out prevention plate 10 that suppresses blow-out from the supply port 2 on the tip passage side of the threshed shell culm supply port 2 of the threshing device 1, and allows the shell culm to pass through while hitting the blow-out prevention plate 10. It is characterized in that it is provided so as to be freely movable backwards around the tip end side of the supply port 2.

In other words, since the blow-out prevention plate 10 is provided on the tip side of the supply port 2 and moves backward around the tip side, this prevention plate 10 is provided with a single sagging film on the supply port 2, as in the conventional case. Unlike the method, it does not fully open by passing through a short culm, and since the center of oscillation is different from that of the sagging membrane, it is difficult to move backward unless the culm comes into contact with it, and as a result, the supply port 2
By adding a simple structure, we have succeeded in effectively suppressing the blow-out from the pipe.
