Description

[Detailed description of the invention] [Industrial application field] The present invention is based on an endless rotary band with a plurality of protrusions that locks and transports planted stem culms to the rear of the machine body and supplies them to the reaping device. A horizontal conveyance path in which the cut stem culms are placed side by side in the horizontal direction of the machine in an upright tilted position located at a high level, and the cut stem culms are conveyed to one side of the machine in an upright position, and the stem culms are secured along this horizontal conveyance path. The present invention relates to a stem culm introducing section of a reaper, in which an endless rotating belt with locking claws for conveyance is provided behind the endless rotating belt with projections.

[Conventional technology]

The above-mentioned reaping machine is capable of supplying the stem culm to the reaping device while the endless rotating belt is pulling up the stem culm due to the upward slope at the rear of the endless rotating belt with projections and the locking of the stem culm by the projections. It is something.

Conventionally, in this type of reaper, for example,
As shown in Japanese Patent No. 27709, an endless rotary belt with protrusions was designed to raise and raise the stem culm to be reaped by itself, and also to supply the reaping device to the reaping device.

[The problem that the idea aims to solve]

Conventionally, the structure of the endless rotating belt with protrusions was simple, and the width at the starting end of the belt was made as small as possible to make it advantageous for stems, culms, etc.
In order to advantageously drive the endless rotating belt, etc., the protrusions are made non-undulating and the length of the protrusions is made as small as possible. The accuracy of the raking supply was reduced, making it more likely that problems with uncut material would occur.

The purpose of this invention is to simplify the endless rotating band with protrusions itself, to enable the stem culm branch to be driven advantageously, and to introduce the stem culm to be harvested with high precision. .

[Means for Solving the Problems] In order to achieve the object, the present invention includes a method in which the stem culm from the endless rotating belt with projections is scraped into the reaping device at the stem culm introducing portion of the reaper mentioned at the beginning. The rotating body with a locking claw to be supplied is formed so as to be rotationally driven by the contact between the locking claw thereof and the locking claw of the endless rotation band with the locking claw, and the endless rotating body with the protrusion is rotated. A rotary body with an undulating claw, which is integrally and rotatably attached to the terminal side winding wheel body for the band and which scrapes the stem culm into the endless rotating band with projections, is attached to the conveyance starting end of the endless rotating band with projections. At the same time, it is interlocked with the endless rotation band with the protrusion. The functions and effects thereof are as follows.

[Effect]

The rotational force of the endless rotating band with a locking pawl is transmitted to the winding wheel on the terminal side by the rotating body with a locking pawl, the endless rotating band with a protrusion rotates, and this rotational force is transmitted to rotate the undulating pawl. The body rotates. In other words, the endless rotation band with a protrusion and the rotating body with an undulating claw can be driven by using the rotation body with a locking claw and the endless rotation band with a protrusion as a transmission member without providing a special transmission mechanism for this purpose. can.

Even if the protrusions of the endless rotating band with protrusions are made into a non-relief type,
Furthermore, the endless rotating band and the locking pawl are provided so that the contact transmission between the endless rotating band with the locking pawl and the rotating body with the locking pawl is advantageous in terms of strength with a relatively short locking pawl. While moving the rotating body as close as possible, even if the protrusion of the endless rotating band with protrusions enters the lateral conveying path when moving from the transport path side to the return path side, it will not come into contact with the endless rotating band with locking claws or the transport path forming member. Even if the length of the protrusions is made relatively short so that the width of the endless rotating belt with protrusions is made as small as possible at the conveyance start end side, as a result, the endless rotating belt with protrusions Even if the performance of raking up the stem culm and the performance of raking the stem culm are slightly degraded, the rotating body with undulating claws raises and floats the stem culm with the raised forming claws, and this is ensured by the endless rotating belt with projections. The stem culm is raked and fed so that it is locked, and the rotary body with a locking claw rakes and feeds the stem culm to ensure that it reaches the reaping device.
In the case of a rotating body with an undulating claw, the locking claw falls down on the non-operating side, and the width of the rotating body with a claw as a whole becomes smaller than that of a non-undulating claw type. Although a rotary body with an undulating claw is provided at the starting end of the band as a scraping and supplying means, the width of the entire body is made as small as possible.

[Effect of idea]

The endless rotating band with protrusions can have a simple structure in which the protrusions do not rise and fall, and the drive of the endless rotating band with protrusions and the rotating body with undulating claws can be simplified in structure without a special transmission mechanism. This made it possible to obtain the endless rotating band with protrusions at low cost both in terms of the protruding endless rotating band itself and in terms of the drive system.

For this reason, the width of the starting end of the endless rotating belt with protrusions, which is where the grass is weeded, can be made as small as possible to ensure good weeding with less push-over. Due to the rotary body and the rotary body with locking claws, the lifting by the endless rotating band with protrusions and the supply of the reaping device can be done without mistakes as much as possible, and even if the degree of lodging of the stem culm is large, there will be no uncut material. It has become possible to perform difficult and efficient harvesting operations.

〔Example〕

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

As shown in FIGS. 1 and 2, a self-propelled vehicle is equipped with a wheel 1 whose installation height can be changed by adjusting the swing of a transmission case 2 relative to the wheel 1, and an engine 3 mounted behind the wheel 1.
