Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a long seedling mat formed by sowing seeds of a plant such as rice and vegetables on a long strip-shaped seedbed sheet made of non-woven fabric, and winding the seedling while tilting it in a predetermined direction. The present invention relates to the structure of the device.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Unexamined Utility Model Publication No.
As disclosed in No. 1 Publication, etc., a seedling mat having a rectangular shape in a plan view is placed on the surface of a seedling placing table that is inclinedly arranged in a seedling transplanter of a riding type rice transplanter and that reciprocates left and right. Planting in a field is performed while dividing into seedlings of a suitable size (seedlings for one strain) by a pair of planting claws of a seedling transplanting mechanism that rotates at the lower end of the seedling mounting table.

[0003] By the way, the conventional seedling mat is arranged so that its longitudinal direction is along the vertical inclination direction of the inclined seedling mounting table, and the lengthwise dimension of the seedling mat is about 58c.
m, the width dimension is about 28 cm, and every time a seedling mat is consumed, it is necessary to frequently add and supply a new seedling mat on the seedling mounting table. It has been proposed that a mat be transferred from a spare seedling stand provided on a side surface of a traveling body of a rice transplanter to an upper end direction of a seedling stand and be inherited.

However, as long as the length of the seedling mat is short, the number of times of replenishing and supplying the seedling mat becomes frequent, and it is necessary to supply the seedling mat to stop the traveling machine each time, and the rice planting work is performed. It was a cause of hindering efficiency. Therefore, if the seedling mat is formed in a belt-like (strip-like) shape, the placement of the long seedling mat as it is on the seedling mounting table is extremely troublesome and the seedling mounting table becomes too long. It has been considered that the long seedling mat is wound up in a roll shape, and the long seedling mat is unwound and supplied to the lower end direction of the seedling mounting table.

[0005]

However, since the seedlings are erected substantially vertically on the surface side of the long seedling mat, if the seedlings are wound up as they are, the seedlings may fall in random directions or the seedlings' stems may fall. Also, there was a problem that the middle of the leaf was broken and damaged. Further, when the seedlings are tilted in the width direction of the seedling mat, when the seedling mat is divided into one strain by a pair of left and right planting claws arranged in the width direction, the midway part of the fallen seedlings is There is a problem that the frequency of cutting with a planting nail increases, and even if it is planted in a field, seedlings cannot be grown.

The present invention has been made to solve the above-mentioned problems, and the long seedling mat is pretreated by inclining the seedlings on the surface of this kind of long seedling mat in a predetermined direction in advance. It is an object of the present invention to provide a device for winding a roll into a roll. The present invention can be applied not only to rice seedlings but also to long seedling mats for seedling transplanters for flowers, vegetables and the like.

[0007]

In order to achieve the above object, the guide device for the winding device of the long seedling mat according to the invention of claim 1 is a long strip-shaped nursery sheet made of non-woven fabric or the like and rice or vegetables. A long seedling mat, in which seeds of plants such as the above are sown and grown, is configured to be transported to a winding device via a transporting means along the longitudinal direction thereof, while the transporting path by the transporting means includes a long seedling mat. The posture correcting means is arranged to convey the seedlings on the surface of the long seedling mat to the winding device side while forcibly inclining the seedlings backward in the longitudinal direction.

According to a second aspect of the present invention, in the guide device for the winding device of the long seedling mat according to the first aspect, the posture correcting means extends along the longitudinal direction on the surface of the long seedling mat. In addition, the rotary endless belt is slanted toward the downstream side of the conveyance.

[0011] Therefore, the seedbed sheet 14 laid in the seedling raising tray 11 is sown with pre-germination-treated paddy and allowed to stand for 3 to 4 days in a germination room (not shown) at a predetermined temperature and humidity for germination. After that, the seedling-raising tray 11 is moved to a greening room (not shown), the nutrient solution is supplied to the seedbed sheet 14 by a water sprinkler, etc., and left for 5 to 7 days under a predetermined environment while being exposed to sunlight. Greening the seedlings and leaves, and a hardening chamber (not shown)
The seedling-raising tray 11 is moved to, and the nutrient solution is supplied to the seedbed sheet 14 by a water sprinkler or the like, and left for 5 to 7 days while being exposed to sunlight to cure the seedlings and the seedling leaves. In addition, each said nutrient solution is circulated independently in each room, and is used.

The long seedling mat 1 having the seedlings 18 grown to a predetermined height in this manner is wound into a roll by the winding device 20 to form the seedling roll 10. In this case, in the present invention, the seedlings of the seedlings 18 of the long seedling mat 1 to be conveyed are the long seedling mats in the conveying path of the long seedling mat 1 to the winding device 20, preferably immediately before the winding device 20. 1
The posture correcting means is provided to feed the tape toward the winding device 20 while performing processing so as to maintain the tilted posture along the longitudinal direction.

FIGS. 4 to 7 show a first embodiment of the winding device 20 and the pretreatment device 21 as a posture correcting means for correcting the tilted posture of the seedlings, and the guide plates 22a, 22b.
An upper pulley 27 is pivotally supported on a downward bracket 26 of a supporting frame 25 located above a conveying means including a conveying roller 23 and a driving motor 24 thereof, and an endless belt 29 made of rubber or the like is provided on the upper and lower pulleys 27, It is wrapped around 28 and arranged in an inclined shape. The upper pulley 27 is a drive motor 30 on the support frame 25.
Also, it is rotationally driven via the speed reduction mechanism 31, the transmission chain, and the like.

In this case, the endless belt 29 is arranged on the downstream side of the conveyance as it goes to the lower end thereof, and is arranged in an inclined shape so that the lower pulley 28 substantially faces the upper surface of the conveyance roller 23. Then, a hydraulic cylinder 33 in which a connecting plate 32 for supporting the left and right shafts of the upper and lower pulleys 27, 28 is provided on the support frame 25.
By adjusting the vertical position with
The surface of the endless belt 29 on the outer circumference of the is capable of adjusting the force pressing the surface of the long seedling mat 1. In addition, endless belt 29
Is slightly wider than the width of the long seedling mat 1.

As shown in FIGS. 6 and 7, the winding device 20 includes at least one of a pair of support shafts 36 and 37 which rotatably support by engaging both ends of a hollow pipe-shaped winding reel 35. An actuator 40 such as a hydraulic cylinder that allows the support shaft 36 to move back and forth in the axial direction is provided. One support shaft 36 or 37 is rotationally driven by a power mechanism 38 such as a drive motor and a speed reducer. As means for winding the start end 1a of the long seedling mat 1 around the take-up reel 35,
In the illustrated embodiment, the base end of the flexible winding piece 39 is fixed to one side of the circumferential surface of the take-up reel 35, and the starting end 1a of the long seedling mat 1 (the portion not having the seedling 18) is wound up. It suffices to start winding while sandwiching it with the circumferential surface of the reel 35.

The take-up reel 35 also includes a pair of side plates 4.
When the long seedling mat 1 is wound by removably fitting or fittingly fixing the 1, 41, and holding the pair of side plates 41, 41 at the distance of the width dimension of the long seedling mat 1 while keeping the position. To prevent winding deviation in the width direction. Further, a large number of air holes 42 are formed in the circumferential surface of the hollow pipe-shaped take-up reel 35 so as to penetrate in the radial direction, thereby improving the air flowability to the take-up inner diameter portion when the seedling roll 10 is formed.

According to this structure, the endless belt 29, which is slanted with respect to the surface of the long seedling mat 1 conveyed in the direction of the arrow A, is rotated in the direction opposite to the conveying direction while the lower end of the endless belt 29 is approached. Long seedling mat 1 by driving
The stalks of the upper seedlings 18 are forcibly corrected so that they fall toward the side opposite to the conveying direction. In this way, the long seedling mat 1 in which the seedling 18 has fallen in a predetermined direction is vertically sandwiched by the pair of feed rollers 43, 43 and sent out toward the winding reel 35 in the winding device 20. The seedling roll 10 is finished.

As described above, while the long seedling mat 1 is being conveyed, the seedling 1 is prepared by the pretreatment device 21 as a posture correcting means.
It is possible to improve the work efficiency because a series of operations of tilting the stalk 8 to the rear in the transport direction and then finishing the seedling roll 10 by the winding device 20 can be performed in a flowable manner. FIG. 8 shows a modified example of the pretreatment device 21 as the posture correcting means, in which the transport roller 23 is arranged at a position higher than the guide plate 22a on the transport upstream side, and the transport roller 23 has an upper circumferential surface on the transport upstream side. The long seedling mat 1 is conveyed while supporting the lower surface of the long seedling mat 1 in a convex curved shape. As a result, the tip end direction of the stems of the seedlings 18 of the long seedling mat 1 to be conveyed can be displaced in advance so as to be inclined toward the upstream side of conveyance, and thus the lower surface of the endless belt 29 arranged in a slanting shape above the stems. Therefore, it is extremely easy to correct the stem of the seedling 18 in a fallen posture.

In the above-mentioned two embodiments, a transporting long seedling mat 2 for supporting and transporting the lower surface of the long seedling mat 1 is used.
By setting the peripheral speed of the endless belt 29 higher than the peripheral speed of 3, the effect of correcting the fallen posture of the stem of the seedling 18 can be improved. In addition, as shown in FIG.
By providing the raised and raised guide ribs 44, 44 on both the left and right sides of the guide plate 22b located in front of, the conveyed long seedling mat 1 can be reliably guided so as not to be laterally displaced with respect to the winding reel 35. Further, by guiding the left and right sides of the long seedling mat 1 to the side plates 41, 41 on the left and right sides during winding, the pushed down seedlings can be prevented from protruding in the width direction of the long seedling mat 1.

Further, as shown in FIG. 7, through holes 45 are formed in the radially outer side portions of the side plates 41, 41 on the left and right sides, while fitting portions 46a having a U-shaped cross section at the left and right ends.
By fixing the outer peripheral frame 46 provided with 46a via the pins 47, 47, the outer periphery of the seedling roll 10 can be gently pressed so as not to loosen. In addition, the winding device 2
In order to temporarily store the seedling roll 10 taken out from 0,
A support shaft (not shown) may be inserted through the inner diameter portion of the take-up reel 35 to stack the plurality of seedling rolls 10 with the axis of the take-up reel 35 in the vertical direction. , Take-up reel 3 with its axis horizontal
Both ends of 5 may be supported by the storage frame. Furthermore, by rolling the seedling roll 10 to a diameter smaller than the outer circumference of the left and right side plates 41, 41, the side plate 4 can be moved during movement.
The outer periphery of 1 can serve to protect the outer surface of the seedling roll 10.

In this way, after the seedlings are straightened along the longitudinal direction of the long seedling mat 1, the starting end of the long seedling mat 1 is mounted on the winding reel 35 of the winding device 20 and wound. At the time of picking up, since the seedlings of the seedlings 18 are arranged side by side along the winding direction, the seedlings do not suffer from inconvenience such as being broken at the time of winding, and a good seedling roll 10 can be formed. Of.

When the posture of the long seedling mat 1 is corrected so that the tip of the seedling 18 of the seedling 18 falls toward the side where it is rolled up, the seedling roll 10 placed on the upper end of the seedling table 7 of the rice transplanter is used. When the long seedling mat 1 is unwound, the root side of the seedling 18 reaches the lower end of the seedling mounting table first, so the seedling posture when splitting into 1 field by the planting claw and planting in the field is good. .

Therefore, contrary to the above, when the posture of the long seedling mat 1 is corrected so that the tip of the stem of the seedling falls toward the side opposite to the side in which the long seedling mat is rolled up, the outer peripheral end of the seedling roll 10 once wound. May be rewound by another winding device so that it is on the inner diameter side of the winding reel, or the long seedling mat 1 is unwound from the seedling roll 10 arranged on the upper end of the seedling mounting table 7 of the rice transplanter. It is preferable to provide a device for inducing the seedling so that the seedling 18 stands upright from the seedbed sheet 14 when the seedling 18 is raised.
