Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a root cutting machine that can efficiently cut onion roots.

(Prior Art) In order to increase the commercial value and taste of onions, it is necessary to keep the size of onions within a predetermined range at the time of harvest. If onions that have grown to a predetermined size are left in the field after the harvest period, they absorb moisture and become soft, making them susceptible to various diseases and having poor storage stability. In addition, those that grow larger than a predetermined size have a poor taste, and furthermore, the product value decreases due to cracking or poor coloring.

It has been found that in order to prevent such overgrowth, it is sufficient to cut the roots when they have grown to a predetermined size. Therefore, attempts have been made to cut the roots of onions using various root cutting machines, and the inventor of the present invention
We proposed the root cutting machine described in Publication No. 55321.

However, since the blade of the above-mentioned root cutting machine is formed obliquely with respect to the traveling direction of the traveling vehicle body, the onion may move or fall during the root cutting operation. However, there were problems such as having a negative impact on the subsequent digging and harvesting work.

(Problem to be solved by the invention) The problem to be solved by the invention is to provide a root cutting machine that can accurately and efficiently cut onion roots without causing accidents such as the onion moving or falling during root cutting work. It is to provide.

(Means for solving the problem) The means for solving the problem in this invention are as follows:
A bracket attached to the front of the vehicle so that it can be raised and lowered; a frame that is attached to the bracket so that it can be pitched and rolled; the frame is installed below the rear end of the frame, and its length along the left and right direction is approximately the same as the width of the vehicle. A cutter having a single blade having a length and having both sides connected and fixed to the frame via a holder, and provided in a direction perpendicular to the traveling direction of the traveling vehicle body, and a cutter that is in contact with the field surface and that is This system is characterized by comprising gauge wheels mounted on both front ends of the frame so as to be adjustable up and down, and a divider slidingly in contact with the field and disposed in front of each of the gauge wheels.

(Function) The onion stems and leaves located in front of the gauge wheel 12 are divided by the divider 14 to prevent damage to the onions, and the height of the frame 9 above the ground, that is, the burial depth of the cutter 11 is adjusted by the gauge wheel 12. is maintained at a predetermined value, the traveling vehicle body 3 is driven, and the cutter 11 cuts the roots of the onion.

(Example) Each drawing shows an example of the present invention.
In the figure, a four-wheeled passenger vehicle body 3 having rear wheels 1 and front wheels 2 has a front support plate 4 provided at the front end.
A bracket 7 is mounted so as to be movable up and down via a lift link 5 formed of a parallel link. A hydraulic cylinder 6 is provided between the upper link 5a of the elevating link 5 and the traveling vehicle body 3, and a pin 5b attached to the tip is slidably inserted and held in an elongated hole 7a provided in the bracket 7 along the vertical direction. By doing so, the bracket 7 can be freely raised and lowered (pitched).

Further, a hit metal fitting 7b is attached to the bracket 7 via a rolling shaft (not shown) extending in the front-rear direction. By attaching the frame 9 extending in the left-right direction to the hitch metal fitting 7b via the hitch pin 7c, the frame 9 is attached to the traveling vehicle body 3 so that it can be raised and lowered, pitched and rolled freely. 8 is a handle for adjusting the inclination angle (pitching angle) between the frame 9 and the bracket 7.

The frame 9 is formed to have substantially the same width as the left and right spacing between the wheels of the traveling vehicle body 3. Holders 10 are suspended from the rear ends of both left and right sides of the frame 9, and holders 10 are attached to the lower ends of the holders 10. It is a single-edged flat blade extending in the left-right direction and having approximately the same length as the width of the vehicle body 3, and is provided on the cutter 11 in a direction perpendicular to the traveling direction of the vehicle body.

As shown in FIG. 2, the cutter 11 is tilted forward and downward to provide a predetermined rake angle with respect to the field.

On the other hand, gauge wheels 12 are mounted on the front end portions of both left and right sides of the frame 9 so as to be movable up and down. Then, each gauge wheel 12 is attached to the handle 1.
3, the height of the frame 9 above the ground (the burying depth of the cutter 11) can be adjusted as desired.

Further, in front of the gauge wheel 12, a conical divider 14 is disposed with the front end being a sharp end so as to be movable up and down, so that when the frame 9 is lowered to the working position, the frame 9
The divider 14 is made to come into sliding contact with the field regardless of the height of the field. 14a is a guide rod fixed to each divider 14, 14b is a stay that attaches each divider 14 to the frame 9 so that it can be raised and lowered,
By arranging the fork portion 12a of the gauge wheel 12 from below near the front end of the stay 14b, when the frame 9 is raised above the working height, the fork portion 12a lifts the stay 14b from below and connects the divider. 14 is made to float above the field.

In the onion root cutting machine configured as described above, when performing onion root cutting work, the hydraulic cylinder 6 is shortened and the lifting link 5 is rotated downward, as shown in FIG. The gauge wheel 12 is grounded with the divider 14 aligned between the cultivation rows. In this state, the handle 13 is operated to adjust the height of the gauge wheel 12, and the depth of embedding of the cutter 11 is adjusted to move the traveling vehicle body 3 forward.

Then, as the divider 14 moves forward while sliding against the field, the stems and leaves of the onions planted in the field are swept aside from side to side by the divider 14, and then,
The cutter 11 cuts the roots of the onion.

During this root cutting work, the depth of burial of the cutter 11 (height of the frame 9 above the ground) is maintained at a predetermined value by the gauge wheel 12, and since the cutter 11 is perpendicular to the traveling direction of the vehicle body 3, The cutting depth of the root by 11 is stabilized, and the cutting resistance of the root acts equally on the left and right sides. This prevents the onion from moving or falling over due to root cutting work.

In addition, since the divider 14 is provided only in front of the gauge wheel 12 to perform a predetermined weeding action, the structure is simple and the weight and manufacturing cost can be reduced. Adjustment work can also be facilitated.
Furthermore, if the holder 10, gauge wheel 12, and divider 14 are arranged on the same straight line as shown in the embodiment, damage caused by the holder 10 can also be avoided.

In addition, since the frame 9 is attached to the traveling vehicle body 3 in a rolling and pitching manner, the gauge wheel 12 can be moved freely regardless of the unevenness of the field.
By properly grounding the cutter 11, the depth of burial of the cutter 11 can be stabilized.

When changing the direction of the working machine at the edge of a field (headland), etc., the hydraulic cylinder 6 is extended and the lifting link 5 is rotated upward, thereby raising the bracket 7. Then, as the frame 9 rises, the cutter 11 comes out of the ground, and at the same time the gauge wheel 12 and the divider 1
4 floats up, so the work machine can be completely lifted. Then, after changing the direction of the traveling vehicle body 3 by an appropriate method, the hydraulic cylinder 6 is shortened and the lifting link 5 is rotated downward to make the traveling vehicle body 3 travel. It is buried and the root cutting action resumes.

When traveling on the road upon completion of work, the divider 14 may be raised and fixed after the hydraulic cylinder 6 is fully extended and the work implement is sufficiently lifted.

(Effects of the invention) In the present invention, the cutter is formed with a single flat blade, has a length that is approximately the same as the width of the vehicle body, and is perpendicular to the direction of travel of the vehicle body.
The root cutting resistance by the cutter acts equally on the left and right sides of the onion, so that the onion can be prevented from moving and falling due to the root cutting, making it easier to dig up the onion afterwards.

In addition, the present invention allows the operator to precisely cut the roots of multiple rows of onions simply by controlling the work machine to move up and down and move the traveling vehicle forward, thereby greatly reducing the labor required for root cutting work during the harvesting season. I can do it.
