Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of an apparatus for winding a long seedling mat that has been grown by seeding plant seeds such as rice and vegetables on a long belt-like seedling sheet made of nonwoven fabric or the like.
[0002]
[Prior art]
Conventionally, for example, as disclosed in Japanese Utility Model Laid-Open No. 6-17421, etc., the surface of a seedling mounting table that is inclinedly disposed on a seedling planting device of a riding type rice transplanter and reciprocates left and right is rectangular in a plan view. The seedling mat is placed on the field while being divided into soiled seedlings of appropriate size (one seedling) by a pair of planting claws of a seedling transplanting mechanism that rotates at the lower end of the seedling platform. Planting is done.
[0003]
By the way, the conventional seedling mat is arranged so that its longitudinal direction is along the up-and-down inclination direction of the inclined seedling mounting platform, the longitudinal dimension of the seedling mat is about 58 cm, and the width dimension is about 28 cm. Yes, each time the seedling mat is consumed, a new seedling mat needs to be frequently added and supplied on the seedling mount. Therefore, in the prior art, the rectangular seedling mat is used as a side surface of the traveling machine body of the rice transplanter. It has been proposed to make the transition from the preliminary seedling stand provided in to the upper end direction of the seedling mounting stand.
[0004]
However, as long as the length of the seedling mat is short, the number of additional feeding operations of the seedling mat becomes frequent, and each time a seedling mat supply operation is required to stop the traveling machine body, which increases the efficiency of the rice transplanting work. It was a cause to hinder. Therefore, when the seedling mat is formed in a strip shape (strip shape), the long seedling mat is placed on the seedling stand as it is because the handling becomes extremely troublesome and the seedling stand becomes too long. It was considered that the long seedling mat was rolled up and supplied to the lower end of the seedling stage while unrolling the long seedling mat.
[0005]
[Problems to be solved by the invention]
However, since the seedlings stand upright on the surface side of the long seedling mat, if they are wound as they are, the seedlings may fall in a random direction or the middle of the seedlings may break and break. there were. In addition, when the seedlings have fallen in the width direction of the seedling mat, when the seedling mat is divided into one stock by a pair of left and right planting nails arranged in the width direction, There is a problem that the frequency of cutting with planting nails increases, and seedlings cannot be grown even if they are planted in a field.
[0006]
Furthermore, when winding in a roll shape, the configuration in which the winding device is fixed in position and the long seedling mat is forcibly moved toward the winding device requires a long and large conveying means, and the entire device is large. There is a problem of becoming. For example, if the rotation speed (angular speed) of the seedling roll is made constant, the winding peripheral speed increases as the roll diameter of the seedling roll increases, so the moving speed of the long seedling mat must be increased accordingly. On the contrary, in order to keep the moving speed of the long seedling mat and the winding peripheral speed of the seedling roll constant, it is necessary to control to reduce the rotational speed as the roll diameter of the seedling roll increases. Moreover, if there is a speed difference between the moving speed of the long seedling mat and the winding speed of the seedling roll, the seedling roll is too tightly wound, or conversely, the extra long seedling mat is supplied at the winding site. There is a problem that it is difficult to perform synchronous control of the winding speed (peripheral speed of the outer periphery of the seedling roll) and the moving speed of the long seedling mat so that the winding cannot be performed neatly.
[0007]
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an apparatus for easily winding a seedling leaf in a roll shape after pre-treating a seedling in a predetermined direction. It is what. The present invention can be applied not only to rice seedlings but also to long seedling mats for seedling transplanting machines such as flowers and vegetables.

[0023]
Further, compressed air is jetted downward from a horizontally long jet cylinder 67 mounted between the left and right side frames 23 and 23 at a position above the gap between the lower end of the inclined belt 34 and the front end of the pressing belt 51 of the seedling pressing device 21. By doing so, the seedlings 15 that have fallen on the inclined belt 34 are prevented from rising, the breakage of the seedlings 15 by the pressing belt 51 is prevented, and the holding action of the lying state is promoted.
[0024]
A rubber hose 68 for supplying compressed air to the horizontally long injection cylinders 65 and 67 and the side injection box 66 and an electric wire 71 to the drive motor 35 are wired along the traveling direction of the winding processing device 17. 69 are attached to a plurality of receiving rings 70 slidably supported on 69. Next, the configuration of the winding device 19 will be described with reference to FIGS. 3, 4, and 8. In front of the lower ends of the pair of left and right side stand frames 75 that are detachably connected to the rear portion of the pretreatment device 18, an inclined horizontally long scooping plate 53 makes its tip close to the upper surface of the bottom plate 12 a of the seedling tray 12. The front wheel 76 provided on the lower surface side of the scooping plate 53 and the rear wheel 77 at the rear end of the lower end of the side frame 75 are configured to be able to roll while being grounded on the upper surface of the bottom plate 12a of the seedling tray 12. .

It is configured so that it can run straight without swinging left or right.
[0025]
Next, the structure of the driving means and the transmission unit that synchronizes the winding speed of the seedling roll 10 and the traveling speed of the winding device, which will be described later, will be described. In order to wind a winding belt 79 as a wide endless belt for winding the long seedling mat 9 in the state 15 lying down on a winding core 80 such as a cylindrical shape, a first fixed roller 81, a second fixed roller 82, A third fixed roller 83, a fourth fixed roller 84, and a fifth fixed roller 85 are rotatably supported by the shaft. Further, a support roller 86 is provided between the left and right side frame 75 above the scooping plate 53 so as to prevent the winding core 80 at the start of winding from dropping off. The upper end of the cover body 87 that covers the front end opening portion between the left and right side frame 75 so as to be openable and closable is pivotally supported by a support shaft 88 that connects the upper ends of the left and right side frame 75. The sixth fixed roller 89 and the seventh fixed roller 90 are also rotatably supported at the inner upper and lower positions of the cover body 87.
[0026]
A base end of a pair of large tension arms 92 is fixed to a rotatable pivot shaft 91 that connects the rear portions of the left and right side frame frames 75 at intervals slightly wider than the width of the long seedling mat 9. Three swing rollers 93, 94 and 95 are rotatably supported on the large arm 92, respectively. Further, a small tension arm 97 is attached to the rotatable pivot shaft 96 thereabove, and a swing roller 98 is rotatably supported at the tip of the small tension arm 97.
[0027]
A winding belt 79 that is slightly wider than the width of the long seedling mat 9 includes a sixth fixing roller 89, a swinging roller 98, a swinging roller 95, a fourth fixed roller 84, and a third fixing roller sequentially from the seventh fixed roller 90. The fixed roller 83, the second fixed roller 82, the first fixed roller 81, the swing roller 94, the fifth fixed roller 85, and the swing roller 93 are wound around to reach the original seventh fixed roller 90. At this time, between the third fixed roller 83 and the second fixed roller 82, there is no transmission portion that transmits power by pressing the outer peripheral surface of the winding belt 79 against the outer peripheral surfaces of a plurality of rear wheels 77 as drive wheels, In synchronism with the rotation of the winding belt 79, the rear wheel 77 is rotationally driven to apply a running force. A shaft 101 that rotates integrally with the seventh fixed roller 90 is driven to rotate from a drive motor 99 provided on the front surface of the cover body 87 via a chain sprocket and chain 100. Further, a tension biasing spring 102 is mounted between the large tension arm 92 and the small tension arm 97 so that the leading ends of the arms 92 and 97 are separated from each other. A predetermined tension is applied. The winding core 80 at the start of winding with the cover 87 closed is supported by the support roller 86 and a part of the winding belt 79 so as not to drop off, and rotates as the winding belt 79 rotates.
[0028]
Next, the winding operation will be described. In the pretreatment device 18 that travels in front of the winding device 19 in the direction of the arrow A, the seedlings 15 of the long seedling mat 9 on the seedling tray 12 are laid down in the front direction of the winding device 19, so that The long seedling mat 9 is wound around the winding seedling 53 from the starting end of the long seedling mat 9 and wound around the winding core 80 that rotates together with the winding belt 79. As the diameter of the seedling roll 10 increases, The small tension arm 96 and the large tension arm 92 rise against the urging force of the urging spring 102, and most of the outer periphery of the seedling roll 10 is composed of the first fixed roller 81, the swinging rollers 94, 93 and the first one. 7 is wound with appropriate strength so as to be surrounded by the outer peripheral surface of the winding belt 79 located between the fixed rollers 90 (see the two-dot chain line state in FIG. 3).
[0029]
When the pre-treatment device 18 completes the operation of falling the seedling 15 of the long seedling mat 9 on the seedling tray 12, the pretreatment device 18 is wound between the engagement pin 56 and the connecting hook body 54. Remove from the take-off device 19. Next, the winding belt 79 is rotated so as to wind up the end portion of the remaining long seedling mat 9, and when the winding operation is completed, the cover body 87 is opened. In this case, as shown in FIG. 8, the base end of the link 104 is pivotally supported by the pivot pin 103 on the outer surface of the pair of side frame frames 75, and the bent link is attached to the distal end of the link 104. The tip of 105 is pivotally attached to the side surface of the cover body 87 by a pin 106, and on the other hand, one end of a bell crank lever 106 pivotally supported on the end of the pivot shaft 91 and the link 104. When the spring 107 mounted on the middle part passes through the portion of the pivot pin 103, the link 104 is urged upward beyond the so-called fulcrum, so that the cover body 87 can be held open. it can. For safety, it is preferable that the stay body 108 keeps the cover 87 open.
[0030]
When the cover body 87 is opened, the outer periphery of the seedling roll 10 is released from the holding by the winding belt 79, so that the operator can easily take out the seedling roll 10 (see the two-dot chain line state in FIG. 8). ). When the winding device 19 is used alone, a portion of a fixed roller (such as the sixth fixed roller 89) at an appropriate position is driven to rotate by a manual handle (not shown) instead of the drive motor 99. You may comprise.
[0031]
As in the above embodiment, when the long seedling mat 9 is mounted on the winding core 80 and wound, the seedling leaves fall down side by side along the winding direction. Inconvenience does not occur, and the seedling roll 10 can be formed. As described above, when the long seedling mat 9 is laid down so that the tip of the seedling is tilted toward the roll-in side, the long seedling mat 9 is long from the seedling roll 10 arranged at the upper end of the seedling mount 7 of the rice transplanter. In the state in which the seedling mat 9 is rewound, the root side of the seedlings reaches the lower end of the seedling stage first, so that the seedling posture is likely to be good when the seedling mat 9 is planted on the field by dividing each plant with a planting claw.
[0032]
Therefore, contrary to the above, when the posture of the long seedling mat 9 is corrected so that the tip of the stem of the seedling is tilted toward the side opposite to the side where the long seedling mat 9 is rolled up, the seedling placed at the upper end of the seedling mount 7 of the rice transplanter It is preferable to provide a device for inducing seedling leaves so that when the long seedling mat 9 is rewound from the roll 10, the seedling 18 stands almost upright from the seedbed sheet 11.
[0033]
