Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a reaping section for planted shell culms, and a threshing section for threshing while transporting the cut shell culms backward in the direction of movement of the machine using a clamping and conveying device. This invention relates to a walkable agricultural combine that is equipped with a disk-shaped cutter that shreds the waste straw after threshing, and a dropper that collects the straw as it is and releases it in fixed quantities.
The size and shape of the machine body in a one-dimensional view must be able to ensure the safety of walking workers, which is required for a walking agricultural combine harvester, and to switch the processing of waste straw to shredded straw and long straw. The main point is that it has a compact structure without making any major changes.

1. In other words, for a combine harvester, the waste straw after threshing can be processed by switching between two types of processing: one that shreds the waste straw and returns it to the field, and the other that collects the waste straw as long straws. Because of the lack of use of shredded straw as compost, it is desirable to use a disc-shaped cutter that can spread shredded straw over a wide area.

On the other hand, for a walking agricultural combine harvester, it is necessary to configure the machine so that there is no self-propelled body part behind the worker, in order to prevent the walking worker from accidentally falling during work. .

In order to ensure the safety of these workers, conventionally, the control unit for operating the aircraft was placed on the side of the aircraft beyond the outermost part of the self-propelled aircraft, or was placed at the very rear of the aircraft. However, it has a wider body or a longer body.

The present invention has been made with attention to such points, and in the above-mentioned walking agricultural combine harvester, the disc-shaped cutter is arranged so that its receiving port for receiving straw runs along the width direction of the machine body. It is arranged at the rear of the threshing section, and the control operation section of the machine body is formed on the side of the disc-shaped cutter at a position corresponding to the rear of the clamping and conveying device of the threshing section, and the culm direction of the waste straw is aligned along the traveling direction of the machine body. In order to focus and release the straw, the longitudinal direction of the straw dropper is aligned along the longitudinal direction of the machine body, and the straw dropper is placed between the disk-shaped cutter and the operating section, and also by a swing sorting device of the threshing section. and a switching mechanism disposed on a lateral side of the threshing section that overlaps in the longitudinal direction of the machine body, and selectively supplies the waste straw conveyed by the clamping and conveying device to the disc-shaped cutter or the waste straw dropper;
The present invention is characterized in that it is equipped with an attitude changing mechanism that corrects the attitude of the waste straw supplied to the waste straw dropper side in the longitudinal direction of the machine body.

That is, the waste straw after threshing is configured to be selectively switchable between a dropper treatment in which it is collected and released as long straw, and a cutter treatment in which it is returned to the field as shredded straw, thereby satisfying the requirements for waste straw treatment. Then, the waste straw is fed to a disk-shaped cutter that shreds the waste straw almost simultaneously over its entire length, for example, by a machine on the opposite side of the waste straw holding and conveying device for threshing. The actual length of the waste straw can be substantially shortened by feeding it to the cutter while bending the path toward the tank side, or by dividing and shredding the base of the waste straw before reaching the disk-shaped cutter. By supplying it to a disc-shaped cutter, etc., a space where no self-propelled body part exists at the rear is created on the side of the disc-shaped cutter, and by arranging the control unit in this space, the size of the aircraft can be adjusted. In order to ensure safety for pedestrian workers without significantly changing the shape, the dropper is placed on the side of the threshing section, which overlaps with the swinging sorting device of the threshing section, and the receiving posture of the waste straw is adjusted to the front and back of the machine. By arranging the long straw to be discharged in a position facing toward the worker and out of the walking range of the worker, it is possible to equip the machine with a dropper without having to widen the width of the machine. This eliminates the possibility of workers getting stuck while walking due to long straw, which can be expected to improve safety by eliminating factors that could cause workers to fall, and the size and shape of the machine as a whole will be significantly changed. It has become possible to switch between shredded straw and long straw without any problems, and to ensure safety for pedestrian workers by properly arranging the operating section and the dropper.

Moreover, since the dropper can be attached using the lateral wall of the threshing section, it can be attached firmly.

Next, embodiments of the present invention will be described in detail based on the drawings.

Packers 2, 2 and a reaping device 3 are provided on the backs of a pair of lifting devices 1, 1', one of which controls vertical feeding, to constitute a reaping section 4 for the planted culm, and behind this, the reaping culm is installed as a machine. A conveying device 5 for conveying the harvested husk to the rear while lying down inside the body is provided, and a threshing section 1 for threshing the harvested husk while conveying it rearward by a clamping and conveying device 6 is mounted on the self-propelled machine body.

Then, the waste straw from the threshing section T is conveyed rearward by the ear locking device 8 and stock head clamping and conveying device 9 toward the side of the machine tank opposite to the clamping and conveying device 6 while changing the path. A disk-shaped cutter 10 is disposed below the conveyance end for simultaneously shredding almost the entire length of the waste straw gathered on the side of the machine tank, and the cutter 10 is placed on the side of the machine tank. A control operation part 11 is provided in the space on the other side of the cutter which is arranged side by side, and a paddy recovery device 12 is provided on the side of the threshing part 7 and in front of the control operation part 11.

An inclined chute 14 is provided on the upper part of the swinging rack 13 of the swinging sorting device facing below the transport device 8°9, and at the end of the transport of the stock head clamping and transporting device 9, there is provided a straw clamping and transporting device. A switching mechanism 15 for releasing the pinching conveyance is provided, and the pinching conveyance device 9 releases the pinching conveyance on the terminal end side in conjunction with the stoppage of the operation of the tip side locking conveyance device 8.
By this switching, the supply of waste straw to the disk-shaped cutter 10 is stopped, and the waste straw is switched and fed to the chute 14 in an oblique position in a plan view.

Then, the inclined lower end of the chute 14 is directed toward the front and back of the machine body, and a lateral side position of the threshing section 7 overlaps with the swing rack 13 facing the chute 14 and between the cutter 10 and the control section 11. Dropper 16 for releasing long straw
is provided, whereby the waste straw is supplied to the cutter 1o vc by the operation of the measuring and feeding device 8.9, and the head side locking and conveying device 8 is stopped, and the terminal end side of the other stock head side conveying device 9 is stopped. By releasing the conveyance, the waste straw is transferred to dropper 1.
In other words, a mechanism for selectively supplying waste straw to the cutter 10 and the dropper 16 is constituted by the two-way feeding devices 8 and 9, and the waste straw is conveyed in a state facing in the lateral direction of the machine. A posture changing mechanism for supplying the waste straw to the dropper 'Is in the longitudinal direction of the machine body is provided with the two-way feeding devices 8, 9 and the chute 14 when taking the attitude of supplying the waste straw to the dropper 16. A walkable agricultural combine harvester is constructed, which enables switching between a waste straw processing mode in which waste straw is discharged as long straw in the longitudinal direction of the machine body, and a processing mode in which waste straw is discharged as shredded straw.

In addition, when the operating section 11 is disposed on the groove side of the cutter 10, the discarded straw is transported without deforming the discarded straw conveying path, and the discarded straw stock base part to be wrapped around the operating section 11 is divided in advance. It may also be configured to emit shreds.

In addition, in order to feed the waste straw to the dropper 16 in the form of long straw, it is also possible to take a posture in which the stock side is directed toward the front of the machine.

In addition, when supplying the waste straw to the dropper 16, a resistor or the like is provided in place of the head-side locking and conveying device 8, and this resistor is switched between an active state and a non-active state in conjunction with the waste straw switching and supply mechanism. Alternatively, a posture changing mechanism may be configured.
