Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm introducing device for introducing grain f7 into a handling chamber in a top-handling type threshing machine.

In a north-handling type threshing machine, introducing the shell into the handling chamber while being held in an almost horizontal position by the culm pinching transfer device for several seconds is known as prior art in Utility Model Application Publication No. 10 of 1948.
It is known from Japanese Patent Publication No. 195 and Japanese Patent Publication No. 31-7716, that when a culm is held in a substantially horizontal position by a culm pinching transfer device, the tip of the culm is in a state where it is easy to swing in the vertical direction. Therefore, if the culm in such a posture is introduced from the culm introduction port drilled in the front plate on the culm entrance side of the handling chamber as in the above-mentioned publications, the culm immediately before entering from the culm introduction port. Under the influence of the rotation of the handling cylinder in the handling chamber, the tip of the husk sways significantly downward and comes into contact with the edge of the culm inlet, thereby causing the grain to be shed. This causes a delay in the transfer of the tip of the culm.Moreover, as in both of the above publications, the culm is introduced from the culm introduction port drilled in the front plate on the culm entrance side of the handling chamber. In the case of 1i9. Grain is likely to be blown out of the machine by the wind generated by the rotation of the handling barrel in the handling chamber through the culm introduction port, resulting in loss of grain and deterioration of the working environment.

The present invention is intended to eliminate the above-mentioned drawbacks of the conventional ten-handling type dehusking machine.

Therefore, the present invention has a front plate with a culm inlet and a culm outlet (
= A shell culm with an upper handling type handling cylinder mounted between the rear side plate and the outside of the handling chamber (Ill, where the shell culm is transferred along the axial direction of the handling cylinder). A rack transfer device is provided, and the 99. In several top-handling machines in which the starting end of the weighing and pinching transfer device is located closer to the front side of the front plate of the handling chamber when viewed from the culm transfer direction, the front side plate of the handling chamber is equipped with the A shell culm light extending from the lower edge of the shell culm inlet in the front plate toward the starting end of the shell culm transfer device is provided with a plate, and the upper part of the plate is provided with a plate. An inlet cover is provided that extends integrally from the handling chamber cover covering the F section toward the starting end of the several-second clamp transfer device, and a shell culm passage is formed between the inlet cover and the several-second clamp plate. This is what I did.

In other words, with this configuration, the grain f! i! The culm introduction port is guided into the handling chamber from the culm introduction port while being guided in the downward direction by the plate and the entrance cover above it. It turns out. Therefore, it is possible to reduce the transfer delay of the ear tip, and even if grains are shed due to the rotational movement of the handling barrel in the handling room just before entering the handling room from the culm introduction port, this shedding is removed from the machine. Moreover, due to the presence of the plate and the inlet cover in the above-mentioned several-second tray, the grains that move violently in the handling chamber due to the rotation of the handling barrel can be prevented from scattering out of the machine from the culm introduction port. It is possible to reduce the amount of
