Description

[Detailed Description of the Invention] The present invention relates to a continuous pot for raising seedlings in a transplanter, and more specifically, it is capable of raising seedlings to be transplanted to the ridges of a field, and the raised seedlings are continuously placed in the planting mechanism of the transplanter. This paper proposes a continuous pot for raising seedlings, which is characterized by being able to supply a continuous supply of seedlings.

When transplanting tobacco, cabbage, etc. seedlings to the ridges of a field using a transplanter, conventionally the seedlings were collected one by one from the nursery and a temporary seedling tray was installed in the machine body. The seedlings were placed on a pedestal, and as the transplanter moved, the seedlings on the pedestal were sequentially fed by hand to a seedling feeding mechanism provided in the machine.

Therefore, when transplanting seedlings, it is time-consuming to collect the seedlings one by one from the nursery, and while the transplanter is running, the seedlings placed on the seedling stand are manually fed one by one to the seedling feeding mechanism. However, there were problems such as the manual work was cumbersome and the work efficiency was low.

In view of the above-mentioned problems, the present invention involves growing seedlings in continuous seedling-raising pots in which pots for raising individual seedlings are connected.
When planting with a transplanter, by loading the continuous seedling raising pot as it is into the seedling feeding mechanism of the transplanting machine, the seedlings to be transplanted can be continuously and automatically supplied to the planting mechanism one by one. It provides continuous pots.

Further, a seedling pot driving rod 73 is disposed above the bottom plate 72, and this seedling pot driving rod 73 is driven to rotate intermittently in relation to the vertical movement of the seedling holding cup 64. The placed continuous seedling raising pot 9 is intermittently moved to the seedling drop hole 72a at an appropriate length feed rate, and the seedlings to be planted in the seedling growing continuous pot 9 are dropped from the seedling dropping hole 72a into the seedling holding cup 64. The transfer of seedlings is done by a person.

The continuous pot for raising seedlings, which is the essential part of the present invention, will be explained in detail with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view of a state in which continuous pots for raising seedlings are loaded and connected, and FIG. 2 is an enlarged plan sectional view showing a connected state when continuous pots for raising seedlings are juxtaposed and connected.

The continuous seedling growing pot 9 has an appropriate length and height, and is made of a flexible plastic long strip, which is bent at right angles and parallel to each other at appropriate length positions. Side wall portions 9 a and 9 b and an opposing wall portion 9 C extending between opposing ends of side wall portions 9 a and 9 b at a right angle to side wall portions 9 a and 9 b are formed to form a rectangular wave shape. It is constructed by linearly connecting a plurality of seedling growing pots 90 with side walls 9 a and 9 b alternately positioned on the left and right and one side open.

Each end of each opposing wall portion 9C near the side wall portions 9a, 9b has an S-shaped horizontal cross section, and both have a concave groove 9d with an arcuate cross section extending in the height direction and a convex strip with an arcuate cross section. 9e are formed in parallel.

The arc surface of the protrusion 9e and the arc surface of the concave groove 9d are formed to have approximately the same radius of curvature.

And between each open end of the seedling growing pot 90 of one continuous seedling growing pot 9, one side wall portion 9' of the other continuous seedling growing pot 9'.
By intercalating the convex lines and grooves of each of the facing walls 9c and 9'c, both continuous beds for raising seedlings) 9. .9' are elastically engaged so that they can be detachably connected.

Seedling raising continuous pot) By connecting the seedling raising pots 9 and 9', each seedling raising pot 90 becomes a rectangular cylinder.

On the other hand, as shown in FIGS. 3 to 5, the seedling supply mechanism 7 provided in the transplanter has a seedling pot guide section 7 on the top surface of the bottom plate 72 that guides the continuous seedling pot 9 to the seedling drop hole 72a side.
4 is provided, and this seedling-raising pot guide section 74 is provided so as to extend in the front-rear direction of the machine body 1 with two side plates 74a facing each other with a width slightly wider than the width of the continuous seedling-raising pot 9. There is.

A seedling drop hole 72a, which is an opening in the bottom plate 72, is located at a position on the front side of the machine body of the seedling growing pot guide section 74.

Drive shafts 75 and 75 are vertically provided at symmetrical positions with respect to the seedling pot guide 74 on both sides of the seedling pot guide 74 where the seedling drop hole 72a is located.
One end of a seedling pot drive rod 73.73 is attached to the lower end of each of the pots 5.75 and is driven to rotate around the drive shaft 75.75.

The side plates 74 a , 74 a of the seedling pot guide 74 are provided with openings for allowing the tip portion to enter the side plate 74 a when the seedling pot driving rod 73 , 73 is rotated.

Both seedling pot drive rods 73.73 have their tips connected to side plates 74a
When the seedling pot guide part 74 enters the seedling pot guide part 74
The length dimension is selected so that it can come into contact with the concave groove 9d and the convex strip 9e of the continuous seedling growing pot 9 placed therein.

In addition, a drive claw capable of engaging with the concave groove 9d or the convex line 9e of the continuous seedling pot 9 is formed at the tip of the seedling pot driving rod 73,73.

Both seedling pot drive rods 73.73 are configured to be rotated intermittently in conjunction with the operation of the above-mentioned planting mechanism 6, and both seedling pot drive rods 73.73 are driven alternately. ing.

That is, when the seedling holding cup 64 of the above-mentioned planting mechanism 6 is located at the uppermost position, one of the drive shafts 75 as shown in FIG.
rotates, and the drive claw at the tip of one of the seedling pot drive rods 73 engages with the groove 9d or the convex strip 9e of the continuous seedling pot 9, thereby moving the continuous seedling pot 9 toward the seedling drop hole 72a side of the seedling pot 90. The seedling growing pot 90 is moved by one step in length, and the opening end portions of the seedling growing pot 90 are expanded using its flexibility.

As a result, the seedling 10 to be planted, which had been held in the seedling raising box 90, detaches from the seedling raising box 90 together with the soil and falls through the seedling drop hole 72a, and the seedling holder waiting below. The seedlings 10 to be planted are transferred from the seedling supply mechanism 7 to the planting machine 6.

The seedling holding cup 64 holding the seedlings 10 to be planted descends and penetrates into the ground, opens its lower end at the lowest position, and plants the seedlings 10 on the ridge surface.

After planting, the seedling holding cup 64 rises to the seedling drop hole 72.
At this point, as shown in FIG. 4, the other drive shaft 75 is rotated and the seedlings 10 in the seedling raising cup 90 in the next order are placed in the seedling drop hole along with the soil by the same operation as described above. 72 Seedlings 10 are dropped from a and placed in the seedling holding cup 64.
is supplied together with the soil.

Thereafter, the seedling feeding operation described above is repeated to continuously feed the seedlings 10.

Next, a method of using the continuous seedling growing pot 9 according to the present invention when raising seedlings will be explained.

When raising seedlings of tobacco, cabbage, etc. to be transplanted, a large number of continuous pots 9 for raising seedlings are prepared as shown in Fig. 1, and these are connected in the width direction by elastic engagement of grooves and protrusions. to form a seedling box.

Thereafter, soil and fertilizer for raising seedlings are placed in a seedling raising pot 90 formed into a rectangular cylinder by connection, and seeds are sown.

Then, give the appropriate amount of water and raise the seedlings.

When seedlings grow and are transplanted by raising seedlings, the connected continuous seedling raising pots 9.9', 9'', etc. are separated from each other by the elastically engaged connecting portions of each of the connected seedling raising pots 9,9', 9'', etc. Separate each consecutive pot.

When separating the continuous pots 9 for raising seedlings, the continuous pots 9 for raising seedlings to be separated are slightly curved in the length direction compared to the other continuous pots 9' for raising seedlings that are connected, so that the elastically engaged connecting parts can be easily separated. can be made to leave.

Then, when transplanting, separate each seedling in a continuous container)
9. Place an appropriate number of 9'... on the seedling stand 5 of the transplanter.

One of the continuous seedling growing pots 9 is placed in the seedling growing pot guide section 74.
and push the tip of the seedling pot to a position where the tip of the seedling pot drive rod 73 comes into contact with it.

Thereafter, a planting operation lever (not shown) of the transplanting machine is operated to cause the machine body 1 to travel and perform a planting operation.

Due to this planting operation, the seedling pot driving rods 73, 73 alternately and intermittently rotate in conjunction with the seedling holding cup 64 to move the continuous seedling pot 9 placed on the seedling pot guide 74 into one seedling pot 90. The seedlings are moved lengthwise to the side of the seedling drop hole 72a.

Then, when the seedling raising pot 90 is positioned in the seedling drop hole 72a, the seedling 1 to be planted held in the seedling raising pot 90
The seedlings 10 to be planted are continuously and automatically regularly supplied to the planting mechanism 6 by repeating the same operation.

Then, before all the seedlings 10 in one continuous seedling growing pot 9 have been supplied, another continuous seedling growing pot 9 placed on the seedling mounting stand 5 is manually loaded into the seedling growing pot guide section 74. Following one continuous seedling growing pot 9, seedlings 10 are supplied from the next continuous seedling growing pot 9, and the seedlings 10 can be further continuously supplied.

In this way, the continuous seedling raising pot 9 can raise the seedlings 10 to be transplanted, and when transplanting using a transplanter, the seedling feeding mechanism 7 can be supplied with a large number of seedlings 10 to be transplanted in units of the continuous seedling raising pot 9.

In the above-mentioned embodiment, the bottom plate 72a was positioned horizontally, but the portion of the bottom plate 72 up to just before the seedling drop hole 72a may be formed at an angle of inclination so as to be slightly downward toward the seedling drop hole 72H. As a result, the continuous seedling growing pot 9 can be moved more smoothly to the side of the seedling drop hole 72a.

In addition, the tip of the seedling pot driving rod 73 is connected to the continuous seedling pot 9.
It is more preferable to engage the lower part of the concave groove 9d and the convex line 9e in order to smoothly move the continuous seedling raising pot 9.

As detailed above, the continuous seedling growing pot 9 according to the present invention is
A plurality of seedlings can be arranged side by side and connected by engaging the protrusions and grooves, and therefore no parts are required for connection, and seedlings can be raised by putting soil in the seedling-raising pot 90. Since the connection does not come off even when the soil is placed in the seedling-raising pots 90 and the soil is submerged, there is no risk of imbalance in the amount of soil in each seedling-raising pot 90 or root entrapment of the seedlings.

Further, no special member is required to connect the pots to each other, and this connection can be performed quickly.

At the time of transplantation, the continuous seedling growing pot 9 can be easily separated and the continuous seedling growing pot 9 can be loaded into the seedling growing cup guide section 74, so the seedlings 10 to be planted can be transferred one by one from the nursery as in the conventional method. This eliminates the trouble of collecting and transporting the seedlings, and the seedling feeding mechanism 7 that supplies the seedlings 10 to the planting mechanism 6 only needs to be manually fed in units of 9 continuous pots for raising seedlings. This eliminates the need to manually feed 10 plants one by one, thereby increasing the efficiency of planting work and reducing fatigue caused by operating the transplanter.

Furthermore, the continuous pot 9 for growing seedlings after transplantation can be used repeatedly by being connected again, which has excellent practical benefits such as being economical.
