Description

[Detailed explanation of the idea] The present invention relates to a vine mower.

For example, when digging up rhizome crops such as sweet potatoes and potatoes, the stems and leaves of the crop are cut off prior to the digging work in order to facilitate the subsequent tilling, crushing, and land leveling work.

In particular, in the case of sweet potatoes, etc., the vines as stems and leaves cover the entire ground surface of the ridged field, and cutting them is an essential work and must be done reliably.

Traditionally, vertical drum-type equipment and horizontal rotary-type equipment have been used to cut the foliage of this type of vine, etc., but with either type of equipment, only the foliage at the bottom of the ridges can be processed. For this purpose, the stems and leaves are lifted using a separate lifting bar, pulled up, and then cut.

However, with these devices, the lifting bar gets stuck in the soil due to unevenness in the field, or the lifting bar does not work effectively in depressions, making it difficult to lift and set up vines and other stems and leaves, making it difficult to treat the entire surface. It is.

In addition, because a certain ridge width of stems and leaves are cut at one time, the ability to cut all of the thickly grown stems and leaves is insufficient, and clogging often occurs, making it impossible to complete the cutting process.

Furthermore, recently, the height of the ridges in the field has been increased in order to produce high-yielding, high-quality underground crops.
If the height of the ridge is high, there is a drawback that the lifting bar cannot lift up the stems and leaves well.

Therefore, without using a lifting bar, a horizontal blade body is attached to the upper surface of the ridge in the middle part of the drive shaft, and a vertical blade body is attached to the side part of the ridge on both sides of the same shaft. Japanese Utility Model Application Publication No. 53-121341 has been proposed.

However, according to the structure of this publication, as the height of the ridge increases, the vertical blade bodies that are attached to both sides of the drive shaft must be installed in stages with longer lengths, so that the height of the ridge increases.
Therefore, the distance between the lower end of the vertical blade at both ends, where the length is longest, and the upper part of the machine becomes large, which means that the length of the machine increases in the vertical direction, resulting in an increase in size. Since the vertical blade body is attached coaxially with the vertical blade body, even if the rotation radius of the vertical blade body becomes larger than that of the horizontal blade body, there is a limit to it, and the disadvantage is that it is difficult to break off the entanglement with the vines of adjacent ridges in advance. There is.

The present invention was proposed in view of the above points, and is mainly used to cut all over the vines that grow in fields with ridges. The leading mower blade, which cuts the lower part of the tree, is provided on a separate shaft to make the overall length of the machine as short as possible. It is an object of the present invention to make it possible to reliably cut the vines in the lower part of the ridge while preliminarily cutting off entanglements with the vines of adjacent ridges using a cutting blade.

The present invention includes a machine frame equipped with a transmission,
A drive shaft that is horizontally suspended on the machine frame and interlocked with the transmission; a main cutting blade body that is attached to the drive shaft and whose rotating tip fits against the upper surface of the ridge; Rotating shafts on both sides are located at the front lower part of both sides and are rotatably suspended horizontally on the machine frame, and are interlocked and connected to the transmission. The cutting blade body is characterized by having leading cutting blade bodies on both sides that are adapted to the cutting part.

Next, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a pipe-shaped main frame extending on both sides, and a transmission 2 is provided in the center of this main frame 1 in both directions, and a transmission 2 is provided on both sides of this transmission 2 and is shown in front of the main frame 1. Both side connecting frames 3 and a mast 4 are provided protrudingly for a tractor that does not operate, and a reinforcing stay 5 is hung between the both side connecting frames 3 and the mast 4.

Further, the upper part of the side frame 6 as a triangular plate-shaped machine frame is attached to both ends of the main frame 1, so that the side frame 6 is installed oppositely on both sides,
A drive shaft 7 is horizontally suspended between the middle rear parts of the side frames 6 on both sides, and a main cutting blade body 8 is attached along this drive shaft 7, and is positioned so as to cover the upper part of this main cutting blade body 8. Then, a cover unit 9 is horizontally suspended between the side frames 6 on both sides.

The main cutting blade body 8 has ten groups of flail type cutting blades arranged radially around the drive shaft 7, and the diameter increases from the center of the drive shaft 7 toward both sides. By molding, it is formed into something that is almost liquid-like as a whole.

Rotating shafts 11 are located at the front lower part of both sides of the main cutting blade body 8 and protrude inwardly from the side frames 6 on both sides, and the leading cutting blades extend along the respective rotating shafts 11. The body 12 is attached, and a cover unit 13 is attached to the side frames 6 on both sides so as to cover the upper part of each preceding cutting blade body 12.

The preceding cutting blade body 12 has a group of 14 flail type cutting blades arranged radially around the rotating shaft 11, and the diameter becomes smaller from the outer side to the inner side of the rotating shaft 11. By molding it in this manner, it is formed into a substantially conical shape as a whole.

Further, a transmission shaft 15 is mounted inside one side of the main frame 1 so as to pass therethrough, and the inner end of the transmission shaft 15 is interlocked and connected to the transmission 2, and the outer end of the transmission shaft 15 is connected to a sprocket. Power is transmitted to the drive shaft 7 and the rotation shaft 11 on the negative side through the drive shaft 7 and the rotation shaft 11 on the other side through the drive shaft 7 and the transmission chino 17, and also from the drive shaft 7 to the rotation shaft 11 on the other side. Power is transmitted through the sprocket 16 and the transmission chino 17.

In the figure, 18 indicates a chenoke case, and 19 indicates an input shaft.

In such a configuration, when performing vine cutting work, it is connected to a tractor (not shown) via the connecting frames 3 and the mast 4 on both sides, and the input shaft of the transmission 2 is connected to the tractor's power output shaft via a transmission medium (not shown). 19, the main cutting blade body 8 and the leading cutting blade bodies 12 on both sides are rotated via the drive shaft 7 and the rotating shafts 11 on both sides, and the cutting blade moves through the ridged field.

In this case, as shown in Fig. 2, the main cutting blade 8 is positioned on the upper surface of the ridge, that is, the top surface, where the ground surface is completely covered with vines a as stems and leaves. The cutting progresses with the preceding cutting blades 12 on both sides positioned relative to the lower surfaces of the ridge, that is, the side surfaces near the bottom.

Thereby, each vine cutting blade 10.14 of the main cutting blade body 8 and the preceding cutting blade body 12 cuts the vine a while rotating along the ground surface of the ridge.

According to the present invention, the main cutting blade body and the preceding cutting blade bodies on both sides of the main cutting blade body rotate while adapting to the top surface of the ridge and the lower surface portions on both sides of the top surface. At the same time, it is possible to divide and cut the vines that creep from the top to the bottom of the ridge, and to reliably cut the vines that cover the entire surface of the ridge, and it is necessary to lift and pull out the vines using a lifting bar. Therefore, the cutting operation can be carried out smoothly without clogging the vine to be processed or slowing down the rotation of the device.

At this time, the leading mowing blades on both sides are positioned at the front lower part of the main mowing blade and rotate, so that the root of the lower part of the ridge is cut while cutting off the entanglement with the vines of the adjacent ridge in advance. After that, the main cutting blade can reliably cut the root part of the vine, making it easy to cut the vine as a whole, and cutting the vine at the top of the ridge. Unlike when cutting the root portion in advance, the vine does not slide down to the side and become difficult to cut.

In addition, since the main cutting blade body and the leading cutting blade body are attached to separate drive shafts and rotating shafts arranged at the front and rear, the overall history of the machine can be kept as low as possible compared to when they are attached on the same axis. It is possible to achieve miniaturization.
