Description

[Detailed description of the invention] This invention relates to a preliminary seedling stand structure for a rice transplanter.

Conventionally, for example, a spare seedling stand installed behind the seat of a riding rice transplanter has a structure of several tiers on the left and right to hold spare seedlings, but the top tier has a frame that serves as a canopy. Although the structure makes it easy to load spare seedlings, when empty seedling boxes are loaded after using spare seedlings, the empty boxes at the top are likely to fall off or be blown away by the wind.

In this idea, we have created a spare seedling stand structure for the rice transplanter that can prevent empty seedling boxes loaded on the topmost stand of the rice transplanter from falling off and being blown away by the wind by providing a regulation frame on the top of the standby stand. This is what we intend to provide.

A detailed explanation of the embodiment of this invention based on the drawings shows a riding rice transplanter with 6 rows;
It has a seedling planting part a for planting six rows of seedlings at the front, and a running part b behind it, and the seedling planting part a is connected in front of the running part b via a connecting mechanism c. The vehicle is configured to plant seedlings while traveling.

The seedling planting part a has a planting claw 3 connected to the planting mechanism case 1 through a planting mechanism 2, and the planting claw 3 is connected to a seedling block from the lower end of a seedling platform 4 which is low in the front and high in the rear. The machine is used for cutting and planting in the field, and a float 5 is provided below to hold the machine above the water surface of the field.

The running section b has a front wheel 6 and a rear wheel 7 on both sides of the fuselage b', and is driven by an engine 8 installed at the rear of the fuselage b'. While the vehicle is running by operating the handle 10 from the front, seedling planting work is performed using a seedling planting section a arranged in a row in front of the vehicle.

At the rear of the driver's seat 9, a frame 11 whose lower end is connected to the fuselage body b' is erected in an elevated manner to a position higher than the driver's seat 9.

Reference numeral 11-1 indicates the left support of the frame 11, and 11-2 indicates the right support of the frame 11.

On the left and right supports 11-1 and 11-2 of the frame 11, left and right spare seedling stands n and n' are rotatably connected.

Preparatory seedling stands n and n' are each constructed of three tiers on the left and right with steel wire frameworks.
To explain its structure using the spare seedling stand n on the left as an example, 12 is a front frame, 13 is an intermediate frame provided with a sufficient interval to accommodate the width of the seedling box P, 1
4 is also an empty frame, 15 is an upper bottom frame, 16 is a middle bottom frame, 17 is a lower bottom frame, and each bottom frame 15, 1
6 and 17 have a slope that slopes downward from the outside to the inside, and the seedling box P is loaded at the top of the sloped top of the bottom frame with a downward slope, that is, by sliding it from the outside on the bottom frame. .

As mentioned above, the distance between the front frame 12, the middle frame 13, and the rear frame 14 is maintained at a distance _S1 slightly wider than the width of the seedling box P, and the upper, middle, and lower bottom frames 15, 1
The vertical interval between 6 and 17 indicates that the seedlings are placed in the seedling box P.
When P' is stored, the distance _S1 is approximately the same as that from the top of the seedling pine P' to the bottom of the seedling box P, and two seedling pine each are placed in the upper, middle, and lower tiers of the spare seedling stand n on one side.
It is configured so that a total of six sheets of P′ can be loaded.

o is a seedling box loading/unloading opening on the left side of the preliminary seedling stand n partitioned by the front frame 12, intermediate frame 13, and rear frame 14, and corresponds to the upper part of the sloped upper end of the downward sloped bottom frame.

Reference numeral 18 denotes a box holder which projects upward at the lower end of each of the downwardly sloping bottom frames 15, 16, and 17, and has a stopper function to prevent the seedling box P from sliding downward on the sloping bottom frame. fulfill.

Reference numerals 19 and 20 indicate intermediate holding rods installed slightly above the respective bottom frames 15, 16, and 17 in the front frame 12 and the rear frame 14, so that the loaded seedling box P can be moved forward and backward from the front frame 12 and the rear frame 14. It has a holding function to prevent it from protruding towards the side.

In the structure of the above-mentioned preliminary seedling stand n, the gist of the proposed structure is that between the upper end horizontal rods 12-1 and 14-1 of the front frame 12 and the rear frame 14, The regulation rod 21 is erected, and four falling-off prevention rods 22 are installed in a row in the horizontal direction of the regulation rod 21 toward the inclined lower end of the bottom frame. Therefore, it constitutes a regulation frame 23.

The regulating rod 21 is installed from the upper bottom frame 15 at a position slightly higher than the height of the two empty seedling boxes stacked together, and the falling prevention rod 22 extends horizontally from the regulating rod 21 to the upper bottom frame 15. It is stretched and bent downward at the inner end positions of the front frame 12, intermediate frame 13, and rear frame 14.

In addition, the right side spare seedling stand n' has the same structure as the left side spare seedling stand n mentioned above, and 12' is the front frame, 13' is the middle frame, and 14' is the same structure.
is the rear frame, 15' is the upper bottom frame, 16' is the middle bottom frame,
17' is a lower bottom frame, 21' is a regulating rod, 22' is a drop-off prevention lever, and 23' is a regulating frame.

In the figure, 24, 24' are supporting vertical bars fixed to the outer vertical bars 12-2, 12'-2 of the front frames 12, 12', and the upper and lower ends of the supporting vertical bars 24, 24' are the upper and lower ends. The brackets 25, 25', 26, and 26' are rotatably connected to the left and right supports 11-1 and 11-2 of the frame 11, and these mechanisms allow the left and right spare seedling stands to be n, n' are left and right support columns 11-1, 11
-2 is rotatably supported to the outside of the fuselage.

27, 27' are fixing rods for rotating the spare seedling stands n, n' to the outside of the machine and fixing them at a certain position. Bolts are attached to the required points of one end of the fixing rods to the horizontal machine frame 28. The other end is configured to be fixed by tightening or the like, and the other end is attached to the pivot support 29, 2 at the front corner of the preliminary seedling stand n, n'.
9' has been done.

The embodiment of this invention is configured as described above, and when loading the seedlings P stored in the seedling boxes P on the spare seedling stand n, the upper, middle and lower rows of the left side spare seedling stand n are loaded. The seedling box P is placed on the bottom frame 15, 16, 17 from the seedling box loading/unloading port o,
As the seedling planting work progresses, the number of used seedlings on the seedling platform 4 decreases, and as the number of seedlings used on the seedling platform 4 decreases, spare seedlings are placed on the seedling platform 4 from the preliminary seedling platform n, and the empty The seedling box is loaded on each bottom frame 15, 16, 17 of the preliminary seedling stand n. When loading empty seedling boxes in the spare seedling stand n in this way, the middle and lower bottom frame 1
Since the empty seedling boxes loaded on the containers 6 and 17 have the upper bottom frame 15 and the middle bottom frame 16 located above, the empty seedling boxes will not be blown away by vibrations or wind during driving. Moreover, the empty seedling box loaded on the upper bottom frame 15 is prevented from flying upward by the regulating rod 21, and when the empty seedling box is loaded twice, the upper empty seedling box is The falling-off prevention rod 22 prevents it from falling down the slope.

In addition, since each of the bottom frames 15, 16, and 17 is sloped downward from the seedling box loading/unloading port o, both seedling boxes and empty seedling boxes are loaded with their tips slanted toward the box holder 18. , so as not to fall outward from the seedling box loading/unloading opening o.

Regarding the spare seedling stand n' on the right side, the same effect is used to prevent the empty seedling boxes from falling off and scattering by the regulating frame 23'.

According to this invention, a restriction frame is provided at the top of the reserve seedling stand, so even if empty seedling boxes are loaded on the top of the reserve seedling stand, the empty seedling boxes may be blown away by the wind or tilted due to vibrations during driving. It is possible to prevent the seedlings from falling out of the preliminary seedling stand, and the work of carrying in and out of the seedling box can be easily carried out, which has the effect of contributing to improving the efficiency of the work of planting seedlings.
