Description

[Detailed Description of the Invention] The present invention relates to a transplanting machine for field crop seedlings, and its purpose is to provide a transplanting machine that facilitates high-ridge transplantation.

When seedlings of field crops, such as beets, onions, and corn, are cultivated in high ridges, the wind speed flowing through the ground is slowed down, preventing wind damage, and the fertile soil on the ground is gathered around the seedlings, resulting in better growth. Since we use dogs, we have a good supply of oxygen, which promotes the decomposition of organic matter, and also increases the soil temperature.
Moreover, it has many advantages such as preventing moisture damage to crops.

Conventionally, in high ridge cultivation, a field is leveled, high ridges are created manually or with an independent ridge leveling machine, and seedlings are planted and grown one by one on the ridges.

However, this method has the disadvantage that it requires a lot of labor and time compared to flat ridge cultivation. A method of creating high ridges has also been considered.

However, with this device, the desk coulter is fixed to the transplanter, so when the transplanter is towed by a tractor and moves forward, the machine moves up and down following the unevenness of the field, and the transplanter adjusts the transplant accordingly. I do.

However, with the desk coulter, the height of the mulch fluctuates greatly due to changes in the transplant depth, and it is not possible to mulch the soil in a constant state.

For example, when the transplanter lifts up, the amount of soiling decreases at an accelerated rate, and when the roots are exposed and the transplanter lowers, the amount of soiling increases at an accelerated pace, resulting in the seedlings being buried.

This is an essential drawback when using a desk coulter, but in order to prevent this, it is necessary to adjust the desk coulter by making it deeper or shallower in relation to the field.

However, in practice, this adjustment is a very troublesome task, and an ideal transplanting machine for high-ridge cultivation has not yet been completed.

The present inventor has conducted research to eliminate the above-mentioned drawbacks, to perform transplantation and high ridge formation at the same time, and to form high ridges while transplanting without being affected by fluctuations in the unevenness of the field. The traction rod of the high ridge forming drum is attached, and the point is used as a fulcrum, and it can swing only in the vertical direction.The problem of installing a desk coulter on this traction rod is to eliminate the vertical movement of the transplanter due to unevenness in the field. did.

To explain the present invention in detail with reference to figures, 1 is a tractor;
is the machine frame of the transplanter, and the two are connected via a connecting rod 3 and move in the direction of the arrow.This connection is usually made by a three-point hitch.

A rolling cork 4 is provided on the lower front side of the machine frame 2, and a groove opener 5 is arranged behind the rolling coulter 4 and fixed to the machine frame 2.

The groove opener 5 is preferably for shallow grooves. A planting device 6 is provided behind the trench opener 5. The planting device 6 is preferably a forced planting method having a transplant rod γ, such as a circle-type transplanter (trade name). A pressure wheel 8 is provided at the rear of the planting device 6, which adjusts the height of the planting device so that the seedlings are planted shallowly, to suppress the planted seedlings.

In addition, 9 is a seedling stand fixed to the upper part of the machine frame 2, and the seedlings on the seedling stand 9 (
For example, seedlings 10 grown in paper pots are fed one by one to the transplanting rod 7 manually or by a mechanical device.

A traction rod 11 is loosely supported on the rear end of the machine frame 2 as described above, and the traction rod 11 is fitted with the left and right desk coulters 12 and the left and right high ridge forming drums 13 in that order.
The planting will be completed at the same time as the high ridges are created as shown in the figure.

The present invention is based on the desk coulter 12 and the high ridge forming drum 13.
The pin 14 is inserted into the rear end of the machine frame 2, and the traction rods 11, 11 are loosely supported using the pin 14 as a fulcrum. .

The traction rods 11, 11 extend parallel to each other to the rear of the machine frame 2, and a mounting bracket (desk coulter adjustment rod) 15, 15 is fixed to the upper part of the center of the rod, and is raised upward.

This desk coulter bracket N5,15 has 1 horizontal rod on top.
6 in a direction perpendicular to the direction of movement of the aircraft, and
Desk coulter adjustment rods 17, 17 are loosely fitted into both left and right ends of the desk coulter and fixed with push bolts 18.

A boss 19 is fixed under each adjustment rod 17°1T.
, the shaft 20 is loosely inserted into the boss 19 in sliding contact with the boss 19, and the shaft 20
20 is fixed to the adjustment rod 17 with a split pin 21.

Therefore, the desk coulter 12 is located between the traction rods 11, and can be adjusted in angle and height by the adjustment rod 17 and rotatable by the shaft 20.

A collar 22 is fixed to the rear end of the traction rod 11, a shaft 23 is provided in sliding contact with the collar 22, and on both sides of the shaft 23, two bowl-shaped high ridge forming drums 13° 13 are placed back to back. Fixed to.

The present invention is constructed as described above, and when transplanting, the field is crushed and leveled using a conventional method, the transplanter is pulled by the tractor 1, and the rolling coulter cuts or removes the clutter in the field. The machine is buried in the soil and supported at a constant height by the restraining wheels 8 while traveling. At this time, the trench opener 5 cuts a trench of a predetermined depth, and the transplant rod 7 is forcibly planted in a shallow planting state in this trench. Plant 10 seedlings in.

To explain this planting example using beet seedlings grown in paper pots, these paper pots usually have 10 to 10 seedlings.
Since it has a height of 3z, the height of 5~6.
Plant so that 5 crn is above the ground.

This shallowly planted seedling 10 is suppressed by a single-stage suppression wheel 8,
Next, the soil is collected by the following desk coulter 12, burying the roots, but at the same time forming a high ridge shape.

The height of this ridge is adjusted by moving the adjusting rod 11 up and down, and if the ridge is desired to be made higher, it is lowered, and if it is desired to be made lower, it is raised and the amount of earth is adjusted.

After forming the desired high ridges, the ridge forming drum 13 compresses the slope and the upper surface to complete the high ridges that will not collapse.

When the transplanter of the present invention is used, the transplanter moves up and down depending on the unevenness of the field.

However, the vertical movement of the traction rod 11 with the pin 14 as a fulcrum moves up and down drawing a trajectory that is combined with the vertical movement of the high ridge forming drum 13 and the machine frame 2, and the high ridge forming drum 13 holds both sides of the ridge. Since the vertical movement of the transplanter is eliminated from the rotating part, the error in the height of the mounding is extremely small, and stable high-ridge transplantation is always possible.

The device of the present invention is extremely convenient for transplanting beet seedlings, onion seedlings, and other common upland crops into high ridges.
