Description

  The present invention relates to a transplanter and a transplanter vehicle equipped with the transplanter. More specifically, the present invention relates to a transplanter that can hardly cause unevenness in the amount of covering soil returned to both sides of a planting groove, and a transplanter vehicle equipped with the transplanter. The present invention also relates to a transplanter that enables transplanting even a type of seedling having a root pot, and a transplanting vehicle equipped with the transplanter. Furthermore, the present invention relates to a transplanter that can change the rotational speed of the transplanter and a transplanter vehicle equipped with the transplanter.

  Usually, cultivation of cabbage, onion, etc. is carried out by planting seeds on a nursery bed and replanting them in a farm (plant) when the germinated seedlings have grown to an appropriate size. Seedlings can be cultivated by appropriately planting seeds in a container surrounded by a frame and planted without soil, or on a dedicated nursery bed with a large number of partitioned seedling parts, There is something to be planted with the soiled part around. A seedling provided with such a root pot is generally called a plug seedling or a pot seedling. It is known that even when these seedlings are grown with the same kind of vegetables for the same number of days, the former grows better (easily grows), and the latter tends not to grow so much.

  Such seedlings are conventionally planted in the field using hand planting or transplanting machines. As a transplanter, for example, the one shown in Patent Document 1 developed by the present inventor is known. This transplanter forms a planting groove in the upper part of the cocoon by the groove forming device, plantes the seedling sandwiched between the seedling planting device into the planting groove, and returns the soil to the planting groove by a soil covering roller. It has a structure in which a series of operations of being planted on top are sequentially performed as the vehicle travels.

JP 2001-218506 A

However, the transplanter described in the above publication is sufficiently useful for transplanting seedlings that are not plug seedlings or pot seedlings, but has been found to have the following improvements.
In the above transplanter, when traveling on the ridge, the soil scraped by the groove forming device is swelled on both sides of the implantation groove, and the soil is also scraped by the follower traveling wheels provided between the groove forming devices. Swelled on both sides of the driven wheel. Therefore, a larger amount of soil was raised on the driven wheel side of the implantation groove than on the ridge groove side of the implantation groove. Therefore, the soil that is returned to the planting groove by the soil covering roller is more on the driven wheel side than the ridge channel side, so that the seedling is pushed in the soil and is planted in an inclined state toward the ridge channel side. There was a case. Seedlings that are planted obliquely are not preferred because the growth may deteriorate. In particular, in the case of a seedling of a type having a root pot, the seedling itself is not large, and the covering soil may be covered and withered, which is further not preferable.

  In addition, the transplanter has a structure in which the root is slightly protruded from the edge by the rotating plate so that the buds and leaves are sandwiched. Therefore, if it is a type of seedling without a root pot, it can be planted without any trouble. However, in the case of seedlings with a root pot, the root pot has a considerable weight, so when holding buds and leaves, the stem part of the seedling may break due to the weight of the root pot. This type of seedling could not be transplanted.

In addition, the centerline in the planar view of the groove cutting machine 62, the groove leveling tool 63, and the said implantation machine 4 exists on the same straight line parallel to the running direction of transplanting machine A1 (refer FIG. 8).

FIG. 9 is an explanatory view in which a part of the structure of the transplanting vehicle equipped with the transplanter is omitted.
The transplanting work vehicle has a structure in which the transplanting machine A1 is attached to the rear part of the tractor T, which is a traveling work vehicle. The crop to be transplanted is not particularly limited, but is suitable for seedlings such as cabbage, broccoli, onion, cauliflower and the like.

Here, the tractor T will be described.
The tractor T has a tiller device 80 connected to the rear part thereof so as to be movable up and down. Reference numeral 81 denotes a lower link that connects the mission case 82 and the tilling device 80. Reference numeral 83 is a top link, reference numeral 84 is a lift arm, and reference numeral 85 is a lift link. Reference numeral 86 is a tilling frame, and reference numeral 87 is a chain case. Reference numeral 88 is a tilling cover that covers the tilling claws 89, and reference numeral 90 is a straw forming plate. Reference numeral 91 denotes a support member that supports the tail wheel 92.

  In the transplanter A1, the mounting bracket 10 of the mounting frame 1 is attached to the rear end portion of the support member 91 with a connecting pin, and is detachably attached to the tractor T. Reference numeral 93 is a support link for connecting the rear portion of the seat 13 and the transmission case 82, and reference numeral 94 is a leveling plate for leveling the upper surface of the flange U to a required height. The height of the leveling plate 94 can be adjusted by turning the upper adjustment handle.

(Work)
With reference to FIG. 1 thru | or FIG. 9, the effect | action at the time of planting a plug seedling into a cocoon using a transplant work vehicle is demonstrated.
First, the driver gets on the tractor T. Then, two transplanters ride backwards on the seat 13 of the transplanter A1 at the rear of the tractor T.
The tractor T is caused to travel forward, and the ridge U is formed by the ridge forming plate 90 while cultivating the field with the cultivator 80.

As the transplanter A1 moves forward, the grooving machine 62 runs while rotating in a state of biting into the upper portion of the ridge U, and a muscle groove is formed in the upper portion of the ridge U. Furthermore, the muscle groove is leveled by the groove leveling tool 63 located at the rear, and the implantation groove 100 is reliably formed.
As the transplanter A1 advances, the grounded driven wheel 3 rotates on the upper surface of the kite U, so the rotary shaft 28 rotates through the chain 35, and the implanter 4 also rotates.

  The transplant operator inserts the plug seedling P into the seedling pinching portion B formed by the rollers 42 and 42. The plug seedling P is inserted into the seedling pinching portion B with the root pot N placed on the mounting portion 70 of the mounting member 7 protruding from the edge of the rotating plate 40. As a result, the plug seedling P is held with the buds and leaves sandwiched between the rotary plates 40 and 40. Thus, since the transplanter A1 includes the placement member 7, even the plug seedling P having the root pot N can be implanted without breaking the stem.

  The transplanting board 4 rotates downward while holding the plug seedling P, and releases the sandwiched state by the seedling free part R that spreads the rotating plates 40, 40 at the part corresponding to the planting groove 100, thereby removing the plug seedling P. Put vertically in the implantation groove 100.

Immediately after that, the soil raised on both sides of the planting groove 100 is pressed by the soil covering roller 47 and returned to the planting groove 100, and the root of the plug seedling P is fixed by the pressure of the soil. At this time, the soil returned to the implantation groove 100 is only the soil raised when the implantation groove 100 is formed because the driven traveling wheel 3 is moved rearward. Therefore, the amount of the covering soil returned to both sides of the implantation groove 100 is not likely to be biased.
In this way, the plug seedling P is planted substantially vertically on the ridge U without being inclined obliquely.

  The transplanter A1 has a structure in which the driven traveling wheel 3 travels in the vicinity thereof after the plug seedling P is implanted, and therefore the soil is slightly raised on both sides of the driven traveling wheel 3 after traveling. However, since the soil is not pushed to the implantation groove 100 side, the growth of the plug seedling P is not affected.

  The planting board 4 needs to be set to such a height that the lower edge is in contact with the upper surface of the cocoon when the seedling is implanted. Therefore, the height must be adjusted depending on the soil condition of the field. The height of the implantation board 4 is adjusted by turning the adjustment bolt 51 with the handle 50 of the lifting / lowering adjustment device 5, changing the distance between the bolt mounting member 290 b and the connecting member 331, and changing the position of the driven wheel 3. Is done.

  Further, according to the transplanter A1, the sprocket around which the chain is wound is changed on the gear device 300 side, thereby changing the rotational speed of the implantation board 4 with respect to the driven wheel 3, and the peripheral speed of the implantation board 4 being driven. It can be faster, slower or the same as wheel 3. Thereby, the planting interval of the plug seedling P to be planted on the mounting member 7 can be changed. The planting interval of the plug seedling P is narrowed by increasing the peripheral speed of the planting board 4 and widened by slowing down.

  When the transplanting work vehicle reaches the headland in the field, the lift arm 84 of the tractor T is raised, the transplanting machine A1 is lifted with the transplanting operator on, and a turn is performed to change the direction. At this time, the seat 13 is safe because it remains substantially horizontal. Thereby, working efficiency can be improved.

  The gear device 300 has been configured to include a plurality of sprockets having different numbers of teeth, but this number is not particularly limited. For example, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more can be arranged side by side. Further, the gear device can be provided on the rotating shaft 34 side, or can be provided on both the rotating shaft 28 side and the rotating shaft 34 side.

  In the present embodiment, the swing arm 33 is provided on the rotation shaft 28 so that the rotation shaft 28 becomes the rotation center. However, this is not limited, and the rotation center of the swing arm 33 is the rotation axis. It can also be provided at locations other than 28.

  Moreover, although the case where a plug seedling was planted was illustrated in this Embodiment, this does not limit the kind of seedling which can be used by transplanter A1. The transplanter A1 can also use, for example, a seedling of a type without a root pot. In this case, the mounting member 7 may remain attached or may be removed. The mounting member is attached by bolts and can be removed as necessary.

FIG. 10 shows another embodiment of the transplanter according to the present invention, and is a perspective view with the seat removed.
In FIG. 10, the same or equivalent parts as those shown in FIGS. 1 to 9 are given the same reference numerals. Further, in the following description, the description overlapping with the above-described part of the structure is omitted except for necessary matters.

Reference numeral A2 is a transplanter and includes a mounting frame 1 and a base frame 2a.
The base frame 2a includes side frames 20a and 20a, a middle frame 26a disposed between the side frames 20a and 20a, and a rear frame 21a laid between the rear ends of the side frames 20a and 20a. It is. In the base frame 2a, the front end portions of the side frames 20a and 20a and the middle frame 26a are pivotally attached to the lifting body 15 of the mounting frame 1 so as to be rotatable in the vertical direction.

  Reinforcing members 29, 29 having a linear shape are bridged obliquely between the front portion side of the middle frame 26a at the front portion of the base frame 23 provided on the upper portion of the base frame 2a. Similarly, reinforcing members 29 and 29 are bridged between the rear frame 21 a and the rear portion of the base frame 23.

  A driven traveling wheel 3a is provided in an inner portion surrounded by the middle frame 26a. The driven wheel 3a has a structure in which the belt plate 30a is circular so as to have an outer diameter slightly larger than that of the implantation board 4, and is fixed to the rotary shaft 28 via the spoke 31a. Many protrusions 32a are provided. Therefore, the implanting board 4 also rotates as the driven traveling wheel 3a rotates. On the peripheral edge of the rotating plate 40 of the implantation board 4, mounting members 7 are provided at eight positions at equal intervals.

  A height maintaining wheel 38 is provided at the center of the rear frame 21 of the base frame 2a so as to project rearward. The height maintaining wheel 38 is provided so that the height can be adjusted. Further, the height maintaining wheel 38 is formed with a sufficient width so that it does not easily sink on the upper surface of the heel.

  In the transplanter A2, the driven traveling wheel 3a and the transplanting board 4 are arranged side by side. Therefore, for the reason shown in the column of the prior art, the seedling is easily implanted in an oblique state. If the shape of the top surface of the kite that corresponds to the location where the traveling wheel 3a travels is recessed so that the height is slightly lower than the location where the implantation groove is formed, and the rise of the soil by the driven traveling wheel 3a is reduced, Seedling can be transplanted without any problem.

(Work)
The effect | action at the time of planting a plug seedling using the transplanter A2 in the ridge which has the above-mentioned surface shape is demonstrated.
When the transplanter A2 is run on the ridge, the soil scraped by the groove forming device 6 is raised on both sides of the transplant groove. Further, the soil is also scraped by the driven traveling wheels 3a and is raised on both sides of the driven traveling wheels 3a. However, in this case, since the upper surface shape of the portion where the driven traveling wheel 3a travels is slightly depressed, even if the soil is raised by the traveling of the driven traveling wheel 3a, the soil will fill the dent, It does not appear that a larger amount of soil was raised than the outside. Therefore, when the soil that has been raised on both sides of the planting groove 100 by the soil covering roller 47 is returned to the planting groove 100, the amount of the soil covering on both sides is less likely to be biased.
In addition, description was abbreviate | omitted about the same effect | action and effect which arise with the structure common to above-mentioned transplanter A1.

The terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions.
The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
