Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine harvester equipped with a seeding device, in which the entire seeding device is made into a unit and is installed in the reaping section at the front of the fuselage of the combine.

In recent years, combining harvesters have been equipped with sowing equipment to sow the succeeding crop at the same time as the harvesting of the previous crop, in order to improve work efficiency. Since the seed tank, sowing machine, ground drive wheels, etc. that drive the device are distributed and installed in various parts of the machine body, there are problems such as the troublesome installation and removal of the device.

The present invention addresses the above-mentioned problems with conventional combine harvesters with seeding devices, and by integrally equipping the frame with a seed hopper equipped with a seeding roll and a ground-contact drive wheel that drives the roll,
The seeding device is made into a unit so that it can be easily attached to and removed from the combine harvester, and in particular, the device is installed at the front end of the frame so that it can be easily attached to the harvester in the reaping section provided in the space in front of one of the crawlers moving along the already cut side. By having a configuration in which the cutting side divider is pivoted to the rear, the seeding device can be installed in the space within the width of the machine, and it is possible to sow the seeds in the ground after mowing and press the seeds with the crawler, and furthermore, it is possible to use the seeding device by its own weight or by a separately installed spring. The driving force is used to ensure that the driving wheels are always in contact with the ground with an appropriate ground pressure, and when the reaping section is lifted up when the combine harvester is rotating, etc., the driving wheels do not touch the ground. The sowing operation is automatically stopped by moving away from the plant.

Hereinafter, the present invention will be explained based on the embodiment shown in the drawings. In Fig. 1, 1 is the combine harvester body, 2
3 is a crawler traveling device in the lower part of the machine body, 3 is a reaping section installed through a reaping frame 4 at the front of the machine body 1, and a control section 5 is provided at the front part of the cut side side of the machine body 1. In addition, a device for threshing and sorting the harvested crops supplied from the reaping section 3 by a conveyance device (not shown) is installed inside the machine, and a plurality of grass dividers 6 are installed in the reaping section. , a lifting device 7, a cutting blade (not shown), and the like are provided, and the cutting section can be lifted upward from the shown cutting position by swinging the frame 4. Reference numeral 8 denotes the side of the mown field in the reaping section 3, and a crawler 2a on one side runs along the mowing track.
This is a sowing device installed in the reaping section 3 in the front space of the seeding device, and the device is composed of a frame 9, a ground driving wheel 10 pivotally supported by the frame, and a seed hopper 11 fixed to the rear end of the frame. In addition, as shown in FIGS. 2 and 3, the front end of the frame is pivotally supported by pins 12 to the substrate 6a of the cut-side divider 6 that is integrated with the cutter 3. The rear part of the frame can swing up and down integrally with the drive wheel 10 and hopper 11, and is energized by a spring 13 so that the drive wheel is brought into pressure contact with the ground. Further, a seeding roll 14 is provided at the bottom of the seed hopper 11, and a chain 17 is wound around sprockets 15 and 16 fixed to the shaft of the roll and the shaft of the drive wheel, respectively, so that the rotation of the drive wheel is controlled. Thus, the seeding roll is driven. In the illustrated embodiment, the rear end of the seeding device 8 is connected to a divider support frame 21 via a bending link mechanism 20 constituted by links 18 and 19, and swings about the pin 12. It is intended to prevent lateral deflection of the device without disturbing it.

According to the above configuration, if the machine is run with the reaping section 3 lowered when reaping the previous crop, the ground driving wheels 10 of the seeding device 8 installed in the reaping section will roll over the ground after reaping. By moving, the seeding roll 14 at the bottom of the hopper 11 is rotated via the chain 17, so that the seeds of the succeeding crop stored in the hopper are sown on the ground, and after sowing, the seeding roll 14 is rotated through the chain 17. This means that the pressure is applied by 2a. In this case, the seeding device 8 is swingably supported at the front end of the frame 9, and the drive wheels 10 are biased through the frame by springs 13 so as to be brought into pressure contact with the ground. Even if the reaping part 3 is moved up and down within a certain range to adjust the
The sowing roll 14 is rotated while the sowing roll 14 is securely in contact with the ground, so that there is no loss of seed sowing. Furthermore, if the reaping section 3 is lifted up when the machine is rotating, the driving wheels 10 will separate from the ground and the sowing operation will be automatically stopped, thus preventing seeds from being sown in unnecessary locations. It is. Furthermore, since the seeding device 8 has a frame 9 supporting the drive wheel 10 and the hopper 11, if the pin 12 that pivots the front end of the frame and the pin 22 of the link mechanism 20 that supports the rear end are removed, The entire device can be easily removed when no seeding operations are to be performed. Here, if the required ground contact pressure can be obtained on the driving wheels 10 by the weight of the seeding device 8, the spring 13 can be omitted. In addition, in the illustrated embodiment, the outlet 1 of the hopper 11 is located directly behind the drive wheel 10.
1a is positioned, the seeds are sown in the groove-shaped running track of the drive wheel, and the sowing position is stabilized, as shown in Fig. 4. The seeding groove may be positively formed by pivotally supporting the disc plow 23' on the frame 9' at an angle with respect to the traveling direction and by positioning the hopper outlet 11a' behind the disc plow 23'. Further, a bent link mechanism 20 supporting the rear end portion of the seeding device 8 in the above embodiment is also provided.
Instead, as shown in FIG.
9'' at one end and pin 1 at the other end of the link.
9a'' is engaged with the elongated hole 20a'' formed in the bracket 20'' on the side of the seeding device 8'', thereby preventing the rear part from swinging horizontally without interfering with the swinging of the device about its front end. In particular, according to such a configuration, as shown by the chain line, the pin 1
The vertical swinging of the seeding device is prevented at the position where 9a'' comes into contact with the rear end of the elongated hole 20a'', and it also serves as a stopper. Furthermore, in a configuration in which the divider 6 is removably attached by fitting a shaft 6b fixed to the substrate 6a to the support frame 21 as shown in FIG. 6, a bracket 24 is provided protruding from the shaft 6b. However, the front end of the frame 9 of the seeding device 8 may be pivotally supported on the bracket, and with such a configuration, the seeding device can be attached and removed integrally with the divider, and as shown in the figure. The upper and lower bent portions 24a, 24 are attached to the bracket.
By providing b, it can be used as a stopper against swinging of the seeding device.

In addition, in each of the above embodiments, the seeding device is the second seeding device.
As shown in the figure, the crawler is positioned in front of the already-cut side crawler 2a of the crawler traveling device, so that the sown seeds are suppressed into the ground by the crawler, and further above the crawler. When covering crops with cut straw from harvested crops, as shown in FIG.
All you have to do is set it up.

As described above, the present invention provides a combine harvester with a seeding device, in which the device is integrated into a unit by supporting a seed hopper having a ground-contact driving wheel and a seeding roll driven by the driving wheel on a frame. At the front end of the frame, in the space in front of the crawler on one side, it is integrally supported on the side of the reaping section behind the divider on the already cut side of the reaping section, so that the divider can swing up and down. The attachment and detachment of the seeding device to the combine is significantly facilitated, and in particular, the attachment of the seeding device can utilize the space within the body width of the combine, and the seeds after sowing on the already mown field can be easily removed by the crawler. Pressure is applied immediately, and by ensuring that the drive wheels are always firmly in contact with the ground during sowing operations, it is possible to prevent failure of sowing seeds and the resulting lack of plants in the crop, and to lift up the reaping section. When this occurs, the sowing operation is automatically stopped, which has the effect of preventing wasteful sowing of seeds.
