[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplant layer forming method performed as a pretreatment for planting long onion seedlings and the like, and a transplant layer forming apparatus used in this method.

[0002]

2. Description of the Related Art As a pretreatment for planting long onion seedlings, there is a method of using a transplant layer forming apparatus 80 shown in FIG. The transplant molding device 80 is adapted to be attached to a rear portion of a tractor (not shown) or the like via a link mounting device 81, and a rotary device 82 and a comb-like shape that is held alongside the rear portion of the rotary device 82. Reiki 83
And a cultivator 84 provided behind this reiki 83
And have.

An upper-cut rotary device is generally used as the rotary device 82. The soil mass scraped up obliquely upward in the forward direction (left side in FIG. 5) is crushed in the rotary cover 85 while the fine soil A is crushed. Only the gravel B is passed to the rear of the reiki 83, and the coarse soil B that does not pass the reiki 83 is dropped downward. Therefore, after passing through the rotary device 82, a formation layer is formed in which the coarse soil B is on the lower layer side and the fine soil A is on the upper layer side.

The soil cultivator 84 is adapted to cut open the soil to the left and right as it advances into the formation layer formed by the rotary device 82. Therefore,
After passing through the soil burying machine 84, the soil for soil burying is filled on both left and right sides as shown in FIG. 6 to form the transplant layer E having a groove shape. When transplanting long onion seedlings to this transplantation layer E, the seedlings are placed on the bottom of the groove at predetermined intervals, and an appropriate amount of soil is applied from the embankment portions on both sides according to the growth of the seedlings. Let it go.

By the way, in the case of transplanting long green onion seedlings, deep planting is required in order to lengthen the white roots, so that it is necessary to increase the embankments on both sides of the transplantation layer E accordingly. Therefore, the cultivator 84 is designed to be inserted into a relatively deep position among the formation layers divided by the reiki 83. Therefore, of the above formation layers, the fine soil A
Almost all of the collected upper layers are removed to the right and left sides of the transplanted layer E (that is, embankment), and the transplanted layer E itself, that is, the bottom of the groove contains a large amount of coarse soil B. It becomes a state.

[0006]

When seedlings are planted in the transplanted layer E containing a large amount of the coarse soil B as described above, the density of the ground is low (there are many gaps), and Since it was considered that there was not enough footwear, it was difficult for the seedlings to stand upright, and the survival of the seedlings at the beginning of planting was sometimes slow. Also,
Immediately below the transplantation layer E, there is a plow bottom plate F due to tilling,
The drainage was further deteriorated, and the seedlings were likely to cause root rot due to heavy rain. Therefore, these have been a bottleneck in increasing the harvest rate.

In particular, in clay, the rotary device 8
There was also a problem that the transplanted layer E containing the fine soil A could not be formed unless the tilling by 2 was repeated many times.

The present invention has been made in view of the above circumstances, and an efficient transplantation layer for seedlings is provided so that the uprightness and survival of seedlings can be improved and the harvest rate can be increased. An object of the present invention is to provide a transplantation layer molding method and a transplantation layer molding device that can be molded well.

[0009]

In order to achieve the above object, the present invention takes the following technical means.

[0010] That is, in the present invention 請 Motomeko 1 wherein, at the same time as the tillage by rotary while the layering of the crude soil and Hosodo excited by this rear, fine collected in the upper side of the forming layer Prior to cutting the soil with the soil cultivator, immediately after passing the reiki, the sub soil cultivator inserted deeper than the above soil cultivator cuts the coarse soil collected on the lower layer side by side with the sub cultivator beforehand. The feature is to go.

More specifically, at the same time as plowing with an upper cut rotary, while at the same time separating the coarse soil and the fine soil by reiki on the rear side, a soil cultivator is inserted to a predetermined depth of this formation layer to soil. By cutting out to the left and right, in the method of forming a groove-shaped transplantation layer having embankment parts on both sides, prior to cutting open the fine soil collected on the upper layer side of the formation layer by layering by Reiki with a soil cultivator, Immediately after passing through the Reiki, a small sub-cultivator inserted in a deeper position than the above soil cultivator is used to pre-cut the coarse soil collected in the lower layer to the left and right, and the transplant layer formed by the soil cultivator is cut. It is characterized by mainly using fine soil (Claim 2 ).

[0012] In this way, in the formation layer divided by Reiki, first, a small sub-cultivator cuts the coarse soil on the lower layer to the left and right, and then the soil cultivator removes the fine soil on the upper layer. It will be opened to the left and right. That is,
First, the sub-cultivator cuts the coarse soil to the left and right (that is, it is removed from the center position),
On top of that, the fine soil that has passed through Reiki will be piled up, so that the part through which the soil cultivator passes is already predominantly fine soil. For this reason, the soil on the left and right sides that the cultivator cuts to the left and right (embankment for cultivating soil), and the bottom soil left by the cultivator (soil that forms the upper surface of the transplant layer),
It means that most of them are fine soil.

It is possible to form a crushing groove by a subsoiler in a bottom portion cut open by the subcultivator (claim 3 ). By doing so, there is an advantage that drainage of the transplanted layer is improved by the crush groove and root rot of the seedling can be prevented.

[0014] On the other hand, in the present invention according to claim 4, wherein (implant layer forming apparatus), and uppercut rotary device comprising a Reiki after portion, and the soil machine provided behind the rotary device, forward of the medium earth machine In addition, the present invention is characterized in that it has a small sub-cultivator provided corresponding to the coarse soil that does not pass through the reiki and is dropped to a deep position (claim 4 ). The traveling drive system in the rotary device or the like is not limited to the riding type direct mounting type that is attached to the rear part of the tractor, and may be the walking type direct mounting type or the traction type.

Further, the soil tiller and the sub tiller are 1
It is preferable to make a one-to-one correspondence, but it may be appropriately changed depending on the number of transplant layers (grooves) to be formed by one-time traveling, whether it is one set or a plurality of sets.

It is possible to project a blade of the subsoiler further downward from the subcultivator (claim)
5 ). This configuration is required to implement claim 3 . The sub cultivator can be provided by using a pith pillar of a subsoiler provided before and after the rotary device and the cultivator (claim 6 ). This configuration is also required to carry out claim 3 , but the difference from claim 5 is that when the sub-soiler is originally provided as the transplant layer forming device, the sub-soiler is equipped with the sub-soiler. The point is that the sub cultivator is attached using the pillars. Therefore, in this case, there is an advantage that the mounting structure as the sub-cultivator can be simplified.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of a graft layer forming apparatus 1 according to the present invention. The transplant layer forming apparatus 1 is attached to a rear portion of a tractor (not shown) or the like via a link mounting device 2, and includes a rotary device 4 having a comb-like reiki 3 at the rear portion, and a rotary device 4 of the rotary device 4. The soil cultivator 6 provided at the rear side (further rearward than the reiki 3), the rotary device 4 (reiki 3) and the soil cultivator 6
It has a sub cultivator 7 provided before and after.

As shown in FIG. 3, the soil cultivator 6 and the sub soil cultivator 7 are in a one-to-one correspondence with each other, and their center positions are coaxially arranged to be combined. Two sets are provided in a symmetrical arrangement. Therefore, in this transplantation layer molding apparatus 1, two transplanted layers E (grooves) can be simultaneously molded by one run. The rotary device 4 includes an upper cut rotary 10 and a rotary cover 1 that covers the upper cut rotary 10 from diagonally upper front to rear.
1 and. A power is transmitted to the upper cut rotary 10 from a PTO shaft (not shown) such as a tractor via the drive shaft to the PIC shaft 12 and the gear device 13 by a side drive method (the left side in FIG. 1). The reverse rotation is given to. Reference numeral 15 is a shaft support that holds a lateral transmission shaft (not shown), 16 is a chain transmission device, and 17 is a rotary shaft.

The flat plate provided at the rear of the rotary cover 11 as a general rotary device is removed. Therefore, when the transplanted layer forming apparatus 1 advances as the tractor travels, the rotation of the upper cut rotary 10 causes the soil mass to be scraped up diagonally upward in the forward direction of the traveling direction and crushed in the rotary cover 11. It Then, by this crushing, the fine soil A that has been reduced to a predetermined size or less
Is discharged to the rear of the reiki 3 and the coarse soil B that does not pass the reiki 3 is dropped downward.

Therefore, after passing through the rotary device 4,
The coarse soil B is collected on the lower layer side, and the formation layer C is formed on which the fine soil A is collected on the upper layer side. The soil cultivator 6 has a wing shape that widens toward the end so that the formation layer C can be cut open to the left and right, and is vertical to the support frame 20 extending rearward from the shaft support 15 of the rotary device 4. It is supported via a rod 21. The height of this vertical rod 21 is adjustable with respect to the support frame 20. The height of this vertical rod 21 is adjusted so that the cultivator 6 can be inserted to a depth at which most of the fine soil A on the upper layer side of the forming layer C can be cut open.

The sub cultivator 7 is a size-reduced version of the cultivator 6, and is constructed from the middle of the support frame 20 to the studs 2.
It is supported through 3. The height of the turret 23 is adjustable with respect to the support frame 20, and a blade 24 protruding further downward than the sub cultivator 7 is provided at the lower end portion thereof. The staves 23 are the coarse soil B on the lower layer side in the formation C.
The height of the sub-cultivator 7 is adjusted so that the sub-cultivator 7 can be inserted to a depth at which it can be cut open. Then, a crushing groove G reaching the plow bottom plate F is formed by the blade 24 in the bottom portion cut open by the sub-cultivator 7.

The studs 23 and the blades 24 serve as the subsoiler 2
Since it constitutes 5, the sub-cultivator 7 can be said to be attached by utilizing the turret 23 of the sub-soiler 25.

Transplant layer forming apparatus 1 having such a configuration
Then, of the forming layers C divided by Reiki 3,
The coarse soil B, which is shaken off to the lower layer side, immediately becomes the sub-cultivator 7
By this, it is cut open to the left and right (that is, removed from the center position). And continue from above,
The fine soil A discharged through the reiki 3 is piled up one after another.

Therefore, after that, when the soil burying machine 6 tries to cut open the upper layer side of the forming layer C to the left and right, the depth of passage of the soil burying machine 6 is almost only the fine soil A. Therefore, as shown in FIG. 4, the transplantation layer E formed in a groove shape after passing through the soil burying machine 6 includes soil on both left and right sides (filling soil for soil), and also the upper surface portion of the transplantation layer E (bottom of the groove). Most of the soil in (part) is mainly fine soil A.

Furthermore, in the plow bottom plate F below the transplantation layer E,
A crushing groove G formed by the subsoiler 25 is formed. By the way, the present invention is not limited to the above embodiment. For example, the shape and size of the cultivator 6 and the sub cultivator 7,
The number of installations, the mounting structure, etc. are not limited at all.

Further, the detailed structure of the rotary device 4 is not limited to the above. The present invention is not limited to the case of transplanting long onion seedlings, and can be carried out as a pretreatment in the case of sowing seeds such as burdock and carrot.

[0028]

As is apparent from the above description, in the method for forming a transplanted layer according to the present invention, after rotary tilling, a layer having a predetermined depth is cut to the left and right by a soil cultivator and deeper than this. The sub-cultivator is used to pre-cut left and right ( Claims 1 and 2 ).
Therefore, the small sub-cultivator first cuts the coarse soil on the lower layer to the left and right, and then the soil cultivator cuts the fine soil on the upper layer to the left and right. Therefore, most of the soil on both the left and right sides that the soil cultivator cuts to the left and right (embankment for cultivating soil) and the bottom soil left by the soil cultivator (soil that forms the upper surface of the transplantation layer) are fine soil. There is.

Therefore, the uprightness of the seedlings can be improved, and quick rooting can be realized in the early stage of planting, and the harvest rate can be increased. In addition, even in the case of clay, there is an advantage that the ideal transplantation layer as described above can be formed by plowing once. If a crush groove by the subsoiler is formed in the bottom part cut by the sub cultivator ( Claim 3 ), drainage of the transplanted layer will be improved by the crush groove, and root rot of the seedlings can be prevented. It will be more advantageous in increasing the harvest rate.

On the other hand, in the transplant layer forming apparatus according to the present invention,
It has a rotary device provided with a reiki at the rear part, a soil cultivator provided at the rear of the rotary device, and a sub cultivator provided at a lower position than the soil cultivator between the rotary device and the soil cultivator. Claim 6 ), so claim 1 and
It is possible to obtain the favorable transplantation layer described in claim 2 .

If the blade of the subsoiler is further projected downward from the subcultivator ( claims 5 and 6 ), a fracture groove can be formed on the upper surface of the transplant layer at the same time when the transplant layer is formed. Good drainage described in item 4 can be obtained.
