Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping and harvesting machine that reaps and harvests planted stem culms while running on power.

In conventional reaping and harvesting machines, the reaping and harvesting section was supported on the ground by running wheels, so the cutting height could increase depending on how the running wheels sunk in wet fields, etc., or due to vertical vibration of the machine due to unevenness in the field. There were problems such as the cutting blade changing or becoming covered with mud, which interfered with the cutting operation.

In addition, in order to improve steering performance so that it can be used well in narrow fields, and for example to improve running performance in wet fields by running on ridges and stumps, there is a model with a single running wheel. , the stability in the lateral direction is poor, and the straightness is poor when reaping planted stem culms in rows, making it necessary to make corrections to make them run straight, which causes mental and physical damage to workers. This caused increased fatigue.

In view of these circumstances, it is an object of the present invention to provide a reaping harvester that can have good steering performance and stable straight-line performance, and can perform good reaping without vertical changes in the reaping/harvesting section. purpose.

The present invention has taken the following technical measures.

That is, the center of gravity of the reaping and harvesting section that reaps and harvests the planted stem culms,
A traveling mechanism 12 and a driving mechanism 14 are attached to the first unit, which is configured to stably support the reaping section on the ground with the long float by aligning the center of buoyancy in the front-back direction of the long float in the front-back direction. It is characterized in that the second unit 15, which is integrally assembled with the second unit 15 and the like, is connected in a free swinging state in the vertical direction.

In other words, the reaping harvesting section l has its center of gravity centered on the floats 1 and 2.
By matching the center of buoyancy of the float, almost all of its weight is supported by the floats 1 and 2, and it is stably supported on the ground, so it has excellent followability to the ground, and extremely high stability of the reaping part concubine can be obtained. .

Therefore, even if the second unit 15 sinks in a wet field, etc., it will not sink, and even if the second unit 15 swings up and down due to unevenness on the field base, the first unit 10 will not move up and down on the field. Reaping work can be done well without any displacement.

In addition, by making the floats 1 and 2 longer in the front-rear direction, good straightness can be obtained.Furthermore, since the traveling part and the reaping part are each made into separate units, the first unit N
It is easy to support and lift the entire second unit N5, and it is also easy to lift the floats 1 and 2 to eliminate the obstruction of steering performance due to their straightness and to obtain good steering performance.

Therefore, there are advantages in that it is easy to move along the rows for reaping, exhibits good steering performance, and can work efficiently even in narrow fields.

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

Figures 1 and 2 show the structure of the reaping machine.

Long and thin floats 1 and 2, which are long in the front-rear direction and have their front ends raised upwards, are placed side by side with a space between them on the left and right, and the intermediate part near the rear is reaped. They are integrally connected.

This receiver is provided with a clipper-type cutting blade 5 at the lower end of the plate 3, a stem culm horizontal conveyance device 6 in the middle, and a binding device 7 on the float 1 located at the terminal end of this conveyance device 6. It is set up.

Then, the bone above the front end of the float 2 on the side where the binding device 7 is not provided is provided with a lifting device 8 close to the plate 3 and to the front.

With this structure, the reaping/harvesting section J that lifts up the planted stem culms that are placed between the floats 1 and 2, reaps them, conveys them horizontally, and bundles and releases them is centered in the longitudinal direction by the buoyancy of the longitudinally long floats 1.2. Position the center of gravity and stably support the ground.
This is what makes up Units No.

Further, running wheels 1 are mounted at the center of the frame 11 which is long in the front and back direction.
Mission case 13 supports one wheel of 2 and drives it.
and the engine 14 are integrally assembled to the frame 11 to constitute the second unit N5.

Then, the front end of the frame 11 is connected to the machine frame 4 of the first unit NO. by a pivot shaft 16 having a lateral axis,
The first and second units 10.15 are configured to freely swing up and down relative to each other around the pivot shaft 16.

In order to transmit the power of the engine 14 to the reaping and harvesting vessel, a pulley 17 having the same axis as the pivot shaft 16 is used.
The output pulley 18 of the engine 14 may be connected to the output pulley 18 of the engine 14 for transmission by a belt 19.

Reference numeral 20 denotes a control bundle whose base end is connected to the upper part of the machine frame 4 of the first frame 1, and the bundle 21 is used to lift the first frame 1-0 and support it on the second frame 1, such as when turning. It is composed.
