Description

TECHNICAL FIELD The present invention relates to an improved device for a shaper used mainly for shaping a ridge for green onion planting.

[Prior Art and Problems Thereof] Conventionally, as a device of this type, a device described in Japanese Utility Model Publication No. Sho 49-2027 is generally used.

Also, on both sides of the bottom of the bottom plate of the soil, square timbers are fixed in the front-back direction to form narrow groove molded pieces, placed in the narrow grooves so that hand-planted leek seedlings do not fall, and lean against the side wall of the groove, There is a structure in which a part of the soil in the section is collapsed to cover the soil, but when mechanical planting of leek seedlings has been promoted in recent years, especially in the form of using the soil at the bottom of the groove for covering the soil. In the machine, the groove shape is a deep groove in which both the inner wall portion and the bottom portion are pressed firmly as shown in FIG. 7, and therefore, with the ordinary soil cover plate, the soil at the bottom portion can be collapsed and used as soil for covering soil. Therefore, there was a problem that the planting work of leek seedlings could not be performed efficiently even if the mechanization was attempted.

[Means for Solving the Problem] The present invention is proposed in view of the above-mentioned problems, and it is not necessary to manually transplant the onion seedlings that are performed after the ridge-raising work, To obtain a ridge shaper that can simultaneously use a machine to plant green onion seedlings and cover soil to temporarily prevent fall of the green onion seedlings, and at the same time, take in soil for cover soil as needed. To do.

Therefore, the present invention takes the following technical means.
That is, side pressing plates are extended rearward on both sides of the front guide plate that is curved backward from the lower front end to the upper rear end and has a lateral surface that is substantially orthogonal to the traveling direction. Then, in the ridge shaper configured to distribute the soil scooped by the front guide plate to the left and right by this side pressing plate, an opening is provided in the approximate center of the front guide plate and A ridge shaping device is characterized in that an adjusting body for adjusting an opening amount is provided.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

First, the structure will be described. 1 is a ridge shaper, and the ridge shaper 1 includes a front guide plate 2 and side pressing plates 3 and 3 extending rearward so as to be continuous with both side portions of the front guide plate 2. A space formed by the earth-discharging plates 4, 4 having a V-shape in plan view located above the side pressing plates 3, 3 and the front guide plate 2, the side pressing plate 3, and the earth discharging plate 4 described above. It consists of a swash plate 5 etc. The front guide plate 2 has a lateral surface 2a which is gently curved and retracted from a lower front end to an upper rear end in a side view, and an opening 6 cut out in a short shape is formed substantially in the center thereof. It is provided. The side pressing plates 3 and 3 press and shape the inner wall surface of the groove, and the left and right pressing plates 3 and 3 are both substantially vertical to the bottom surface of the groove and are parallel to each other. The upper edge is curved outwards. The soil discharging plate 4 is provided upright behind the front guiding plate 2 and inside the side pressing plate 3 in order to distribute the soil scooped by the front guiding plate 2 to the left and right, and is shown in FIG. As described above, the center of the soil discharging plate 4 in the left-right direction is configured to substantially coincide with the center of the front guide plate 2, and the rear end of the soil discharging plate 4 is fixed to the inner side of the rear end of the side pressing plate 3. . Reference numeral 7 is a closing plate for closing the opening 6, and the closing plate 7 is vertically slidable along guides 8 fixed to the back surface of the front guide plate 2 and is adjustable in opening amount. Is configured so that it can be changed.

Reference numeral 9 is a long hole vertically formed on the left and right sides of the closing plate 7, and 10 is a bolt fixed to the back surface of the front guide plate 2. The bolt 10 is loosely fitted into the long holes 9 and 9 of the closing plate 7. , Nut 11 is fastened and fixed.

Reference numeral 12 is a support rod for attaching the ridge shaping device 1 to a tilling device or the like (not shown).

In addition, the green onion planting machine 13 shown in FIG.
It is a conventionally known device for mechanically planting while running in a groove after finishing the ridge formation using, and when the structure is briefly described, 14 is between two tapes 15 and 16. A rotary winding body obtained by winding the sandwiched green onion seedling a into a roll,
Reference numerals 17 and 18 denote cylindrical bodies for winding the tapes 15 and 16, and rotations in the directions of the arrows in the figure are given to these cylindrical bodies 17 and 18 via a transmission mechanism (not shown). 19, 1
9 is a seedling holding plate made of elastic rubber, and this seedling holding plate 1
9 and 19 receive the green onion seedling a from between the unwound tapes 15 and 16, and plant this on the ground in a substantially vertical posture. Reference numeral 20 is a squeeze pump that drives this seedling holding plate 19 and squeezes the portion covered with the soil cover plate provided at the front position in the traveling direction.

Next, the operation of this embodiment will be described.

In the above example, when ridges are to be raised as a pre-stage operation of machine planting, the ridge shaper 1 is attached to a rotary tiller (not shown) to advance the machine body.

Then, the soil tilled backward by the rotating claw is lifted upward along the device by the front guide plate 2 of the ridge shaper 1, and a part of the soil passes through the opening 6 formed in the front guide plate 2. As shown in FIG. 5, most of the soil remains on the center of the bottom of the groove formed by the passage of the ridge shaper 1, and most of the soil is the side pressing plates 3 and 3 and the earth discharging plates 4 and 4. Are distributed to the left and right by and to embed on both sides of the groove, and at the same time, the inner wall surface of the groove is formed in a substantially vertical state.

Next, the green onion seedlings are mechanically planted as a second stage work. At that time, as shown in FIG. 4, the green onion seedling planting machine 13 is arranged so as to straddle the ridges which are strongly pressed by the ridge shaping device 1.
Place and move the aircraft forward. Then, the green onion seedlings a sandwiched between the two tapes 15 and 16 are received by the rotating seedling sandwiching plates 19 and 19 and then leaned against the side wall surface of the groove in a substantially vertical posture with the root portion downward. At this time, a soil cover plate (not shown) that is fixedly supported by the machine is used to cover the root of the green onion seedling a with the fine soil remaining in the shape of a strip at the center of the groove bottom to the extent that the root of the green onion seedling a is prevented from falling. The portion of the soil temporarily covered by the subsequent compression wheel 20 is pressed. In addition,
As a work of transplanting the green onion seedlings a, a rotor is further run on the upper part of the ridges to cover the stems of the green onion seedlings a while breaking the ridges, which will not be described.

FIG. 5 shows a state in which a green onion seedling a before being covered with soil is leaned against the inner wall of the groove, and FIG. 6 shows a state after covering and suppressing the root of the seedling. .

[Effects of the Invention] Since the present invention is configured as described above, it has the following technical effects. That is, since the inner wall surface of the groove press-molded by the passage of the ridge shaper 1 is formed in the vertical state as in the past, the onion seedling a can be properly held, and the green onion can be straightened. It will not grow up, fail to grow, or deteriorate in quality.

In addition, even after introducing the planting machine after running the ridge molding machine 1, the soil for covering the soil to the extent that the fall of the green onion seedling a is prevented,
Since a proper amount of soil is being cultivated in the rotary from the opening 6 of the front guide plate 2, it is possible to easily and surely obtain soil for covering soil regardless of soil quality and regardless of groove depth. .

Further, since the opening of the opening is adjusted by the adjuster, it is possible to obtain an appropriate amount of soil according to the soil quality or the rotation speed of the rotary, and the work adaptability is improved.
