Description

[Detailed Description of the Invention] The present invention relates to a threshing machine that is provided with a threshing sorting section below the threshing section and a device for shredding waste straw from the threshing section. By arranging it in a suitable location, the machine body can be made more compact, and the resulting troubles such as dust discharge from the sorting section and straw discharge from the shredding device can be avoided. By rationally configuring the dropper for discharging, the purpose is to make the machine more compact, prevent dropper damage, and improve safety during non-working operations.

In the present invention, in the above-mentioned threshing machine, the shredding device is disposed above the swinging sorting plate of the sorting section, and the straw discharge port of the shredding device is connected to the straw discharge port of the sorting section. The rear wall portion that faces the air exhaust route and forms the dust exhaust port of the sorting section can be swung toward the rear of the machine around the horizontal axis on the upper end side to enlarge the dust exhaust port, and can be fixed in an open position. is provided at the free end side of the rear wall portion, and is capable of vertically swinging between a storage position covering the dust exhaust port and an approximately horizontal working position;
Further, a dropper for converging and discharging a fixed amount of waste straw is attached so that it can be fixed in the storage position.

In other words, by placing the shredding device above the swinging sorting plate, the length of the machine could be shortened.

Moreover, if the shredding device is simply placed at the above location and its straw discharge port faces the ventilation path of the sorting section, the straw discharged from the shredding device will tend to accumulate near the dust exhaust port of the sorting section. This may cause trouble in that the dust from the sorting section and the shredded straw cannot be discharged smoothly to the outside of the device. Since the dust outlet can be kept enlarged by swinging open toward the rear and fixed in the open position, troubles related to the above-mentioned dust discharge and shredded straw discharge can be avoided.

Furthermore, by swinging the rear side wall portion inward and placing the dropper in the retracted position, the unnecessary dust exhaust port can be closed during non-working travel.

Moreover, the longitudinal length of the machine when not in operation can be reduced to two stages by swinging the rear wall inward and storing the dropper attached to the rear wall, making it extremely compact. This is advantageous in various aspects, such as preventing the dropper from colliding with other objects when turning on the road, preventing breakage of the dropper, and improving safety.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below based on an exemplary diagram of a threshing machine installed in a combine harvester.

A winnow 5 that sends sorting air in the direction of the rotational axis of the handling drum 3 below the threshing section 4 configured to thresh the culms supplied to the handling chamber 2 by the feed chain 1 with the handling drum 3 that rotates. ,
A sorting section 7 equipped with a swinging sorting plate 6 is arranged so that the grain culms from the reaping section (not shown) can be threshed and the threshed material can be wind sorted during the reaping movement.

The first item from the sorting section 7 is carried out of the machine by a screw conveyor 8, and the second item is carried out by a screw conveyor 9,
The dust is returned to the handling room 2 by a grain lifting thrower (not shown) and a lifting cylinder 10, and the dust is removed from the machine through an exhaust path 11 and a dust exhaust port 12 provided on the downstream side of the sorting plate 6 in the conveying direction. It is designed to be discharged outside.

The waste straw introduced from the supply port 13 arranged above the case is finely cut by a plurality of disc cutters 15, which are held by a pair of rotating shafts 14, 14, in the direction of the waste straw. cut off,
A waste straw shredding device 17 configured to discharge shredded straw from a discharge port 16 disposed below the case is disposed in a cylindrical place in the wall of the machine body inserted above the sorting plate 6. facing the ventilation path 11, and further provided with a device 18 for conveying the threshing section straw carried out from the handling room 2 by the feed chain 1 to one side of the supply port 13.

The rear side wall portion 19 of the machine body forming the dust exhaust port 12 is configured to be able to swing toward the rear of the machine around a horizontal axis 20 on its upper end side, and when it is in this swinging position, the dust exhaust port 12 is enlarged. It is configured as follows.

A pair of left and right side plates 21 attached to the side wall portion 19.
By inserting and fixing a removable pin 23 into one of the two 21 and a bracket 22 attached to the side wall of the body, a side wall swinging fixing mechanism 24 is constructed which can fix the side wall portion 19 in the swinging attitude. It is.

A swinging lid 25 for the supply port 13 is provided to open and close on its own around a pivot shaft 25a on its lower end side, and when opened, waste straw from the conveying device 18 is transferred to the shredding device 17 by the lid 25. When it is guided downstream and becomes blocked,
The waste straw from the conveying device 18 is discharged outside the machine in the form of long straw by the guiding action of the lid 25.

A dropper 26 that converges and discharges waste straw discharged in a long straw state in a fixed amount at a time, and a pair of left and right guide rods 27, 27 that guide the long straw from the lid 25 onto the dropper 26 are provided.

The dropper 26 is configured to be able to be fixed in a downward swinging manner in a storage position that covers the dust exhaust port 12, and to be able to be fixed in a downward swinging manner in an approximately horizontal operating position, and both guide rods 27, 27 are arranged in a direction that extends in the longitudinal direction of the machine body. It is attached to the ceiling wall of the aircraft so that it can rotate freely around its axis and slide freely in the longitudinal direction of the aircraft.

The straw discharge port 16 is provided with an opening/closing lid that can be vertically swiveled and fixed, and serves as a guide for guiding the straw from the discharge port 16 toward the dust exhaust port 12 in the open state.

A swing type guide plate 29 is attached to the side wall portion 19 to guide the stock side of the waste straw discharged outside the machine in a long straw state onto the dropper 26.

That is, by swinging the lid 25, the supply port 13
When opened, the waste straw from the threshing section 4 is discharged out of the machine from the dust exhaust port 12 in a shredded state.

In this case, as shown in FIG. 2, the side wall portion 19 is fixed in the dust outlet expanded position by the fixing mechanism 24 to prevent shredded straw from accumulating at the dust outlet. It's Nishide.

Further, as shown in FIG. 1, by swinging the lid body 25, the supply port 13 is closed, both guide rods 27 and 27 are pulled out to the rear of the machine body, and the dropper 26 is placed in the working position. The waste straw from the threshing section 4 is discharged to the outside of the machine in the form of long straw, and is caused to fall and be discharged in fixed amounts by the action of a dropper 19.

Furthermore, during non-working driving such as road driving, as shown in FIG.
7. The dropper 27 is placed in the storage position where it is retired to the ceiling wall of the aircraft, the dropper 26 is placed in the storage position, and the guide 29 is placed in the rocking storage position close to the side wall portion 19, thereby,
Care was taken to shorten the fuselage length.
