Description

[Detailed description of the invention] This invention is designed to move the waste straw sent from the threshing feed chain to the inside of the machine by placing it in the middle upper position in the flow direction of the material to be sorted in the sorting section that overhangs at the rear of the handling room. Regarding a threshing device that is equipped with a device for discharging straw that is conveyed at an angle to the rear, the purpose of the threshing device is to provide a clamping rail that is disposed opposite to the feed chain and that is elastically biased toward the feed chain. The strength of the entire threshing device can be increased by a simple structural improvement that utilizes an upper lip plate that is constructed to be strong and located along the upper side of the handling chamber to support the straw removal device. The purpose is to ensure safety and to ensure good transfer of the culm from the feed chain to the straw removal device.

That is, in the threshing device according to the present invention, the upper lip plate located along the upper side of the handling opening extends rearward from the end of the handling chamber, and this extending plate portion is connected to the rail stand installed along the handling opening. It is bent outward to be located near the outer end surface, and a straw removal device is provided with its conveying start end located inside this bent extension plate portion and near the bending point. characterized by something.

First, using the upper lip plate located along the upper side of the opening,
With a relatively simple structural modification of extending the upper lip plate rearward from the end of the handling chamber and bending it outward, the extended plate part of the upper lip plate can be made to overhang rearward from the end of the handling chamber, for example. The entire threshing device can be made into an integral structure by simply connecting it to the structural members of the section or the straw disposal device attached to the end of the threshing device, thereby increasing the strength of the whole. , and by providing the straw removal device with its conveyance start end located near the bending point, the feed chain Since the culm is clamped near the clamping position, the culm can be transferred reliably and well, and by covering the lateral and outer sides of the straw discharging device with the bent and extending plate portion, the discharging straw discharging device This also serves as a safety cover for the straw removal device, making it easy to ensure the safety of the straw removal device.

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

The drawing shows a threshing device, in which the threshing grains leaking from the handling chamber 3 are transferred to a sorting section T configured below the handling chamber 3, in which the handling drum 6 is mounted on an axis, along the axial direction of the handling drum 6. A swinging sorting plate 8 that performs specific gravity selection while swinging and conveying, a winnower 9 that generates a sorting airflow along the axial direction of the handling cylinder 6, and screw conveyors 10 and 11 that collect the first and second grains. At the same time, a dust blower 12 is provided at the terminal end of the sorting section 7 for discharging the dust in the sorting section T to the outside of the machine. At a position above the threshing feed chain 13, there is a waste straw sending device 5 which pinches and conveys the waste straw sent out from the threshing feed chain 13 to the disc-shaped cutter 14.
Its terminal end is located at the rear inside the fuselage in an inclined position.

Of the upper lip plate 2 and lower lip plate 15 forming the handling opening 1 of the handling chamber 3, the upper lip plate 2 located along the upper side of the handling opening 1 is positioned rearward from the terminal end of the handling chamber 3. The cutter cover 16 is extended on the front side wall of the cutter cover 16 covering the outer periphery of the cutter 14, and the two extended plates are placed on the pinching rail 1 in a state corresponding to the pinching and conveying surface of the threshing feed chain 13.
7 is bent outward near the terminal end of the handling chamber 3 so as to be located near the outer end surface of the rail stand 4 attached to the upper lip plate 2 side, and the transport start end of the straw removal device 5 is The bent extension plate portion is located inside the two people and near the bent portion 2a.
