Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet laying apparatus for a multi-transplanter, which lays a sheet in a field using a multi-transplanter while planting an object to be transplanted such as seedlings or seeds.

[0002]

2. Description of the Related Art In recent years, in fields such as rice cultivation or upland cultivation, seedlings are inserted from above the sheets by transplanting nails while the sheets such as vinyl film or sheets based on paper materials are laid in the field. A multi-transplant cultivation method for planting is known, which promotes good cultivation of crops while suppressing weed overgrowth while eliminating the need for herbicides and protecting the environment, and simplifies cultivation management and saves labor. It is attracting attention as a means that can be done.

In a multi-transplanter for mechanically performing the above-mentioned cultivation method, generally, a transplant portion is mounted on a rear side of a traveling machine body so as to be able to move up and down, and a roll-shaped sheet member laterally housed and supported by the sheet support portion is sequentially installed. It is laid out so as to cover the field scene by being pushed and guided by a laying device such as a sled type float or a roller wheel float, and seedlings are planted in the field scene from above the sheet member by means of transplanting claws.

[0004]

By the way, in a multi-working machine for laying a sheet in a field scene with the above-mentioned multi-transplanter, when the pressing force for pressing the sheet against the field scene by the laying means such as a float is too strong. The sheet is entangled in the soil, and if it is too weak on the contrary, the sheet floats up and is easily affected by wind, etc., and the sheet immediately after laying is dragged in the traveling direction by the laying resistance of the float, a so-called sheet There is a problem that tailored seedlings are pushed down due to tailgating.

Further, the above-mentioned sheet member is fixed for a predetermined number of days (40
~ 50 days), when using a paper sheet formed of paper materials to dissolve and reduce it in the field, if the pressing force at the time of laying is weak, this paper sheet will not adhere sufficiently to the rice field surface such as paddy field. If the surface of the plant at the planned planting position (planting locus) does not get wet or the surface of the paper is dry or there is a dry part, the transplanted nail will be transplanted by piercing the part of this part of the paper that grips the seedling. Therefore, there is a problem that the resistance to transplanting and the impact may damage the seedlings such as the waist of the seedling, resulting in poor growth of crops.

In view of the above, the present invention solves the above-mentioned problems of the prior art, and makes the sheet surface of the locus for planting in a groove shape so as to be in close contact with a field scene, thereby facilitating good transplantation and growth of transplanted objects. An object of the present invention is to provide a sheet laying device for a multi-transplanter that can be implemented by a mechanism.

[0007]

A sheet laying device of a multi-transplanter according to the present invention for achieving the above object is to feed a sheet laterally supported in a roll shape to a supporting portion and to run it by the laying device. In a transplanting machine that is laid in a field scene and a planting nail is used to plant an object to be planted on the field from the sheet, a pressing member is provided in front of the transplanting claw to set the position in the planting locus of the sheet to the field scene. It presses so that it may come in close contact, and it is constituted so that an object to be planted may be planted at this pressed portion.

[0008]

[Operation] The sheet S is unrolled from the support portion 9 as the machine body 1 travels, laid so as to cover the field scene, and the locus for planting the sheet S is provided by the pressing member 11 (11a) provided in front of the transplanting nail 8. Since the line is pressed to be brought into close contact with the field scene and the object to be planted is planted at this pressed position, it is possible to favorably grow the crop. Further, when the pressed portion is formed in the shape of a concave groove, the concave groove serves as the planting surface R, so that the object to be planted can be accurately transplanted.

[0009]

[Examples] A configuration of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a passenger rice transplanter B equipped with a multi-device A exemplified as a multi-transplanter, which has front wheels 2 and rear wheels 2a, an engine 4 in the front part, and a driver's seat 3 in the rear part. Installed, the multi-device A in the rear
The transplantation part to which is attached is supported so as to be able to ascend and descend via an ascending / descending link mechanism 5 hydraulically moved up and down and a refraction transmission shaft 5a.

The transplanting section C is a seedling placing table 7 for placing mat seedlings, which is obliquely provided on the transmission case 6 in a front-rear-lower direction, and a seedling placing table 7 is located at the lower end of the seedling placing table 7 to scrape off the seedlings. A plurality of transplanting claws 8 to be planted in the field are provided, and a multi-device A including a support device 9 for a sheet roll (roll paper) S and a roller float (laying device) 10 is provided in front of the lower portion of the transmission case 6. There is.

Further, the supporting device 9 supports the sheet S, which is wider than the planting width and corresponds to the width of the transplantation portion C, in a state of being rolled into a roll so that it can be paid out. Roller float 10
The front roll 10a and the rear roll 10b are swingably attached to the transmission case 6 by a link mechanism having an equalizer fulcrum 10c so that the sheet S can be rolled in the width direction.

The preceding roll 10a has a smooth surface and holds the sheet S that is pressed and nipped with the rice field (field scene) while pulling the sheet S while pulling it so that wrinkles do not occur, and is smoothly laid on the rice field. In addition, the ring body 11 is fixed to the outer periphery of the trailing roll 10b at a predetermined distance in the front position corresponding to the transplanted nails 8 of each strip.

The ring body 11 is a trailing roll 10.
The surface of the b member may be formed integrally with unevenness, but if it is formed of a sponge-like elastic member, the sheet S can be pressed against the unevenness of the rice field so that the sheet S can be pressed against the rice field. The planting locus strip portion can be a planting surface R which is appropriately moistened in advance, and the planting by the transplanting nail 8 can be favorably performed without damage to the seedlings, and resistance when the sheet S is laid is provided. It is possible to perform multi-transplanting work with less shock and vibration.

As described above, the pressing member of the mechanism for pressing the planting locus portion of the sheet S against the streak for positively wetting it prior to planting is the non-rotating sled 11a as shown by the dotted line in FIG. May be installed in front of the transplanted nail 8 of each row, or may be formed on the outer periphery of the leading roll 10a in the same manner as the trailing roll 10b. Reference numeral 12 denotes a pressing device that presses and fixes the starting end of the sheet S on the rice field when laying the sheet S on the rice field, and has a plan view rectangular shape in which an intermediate portion is pivotally supported 13a at an appropriate position of the transplantation portion C. A sheet cutting cutter 14 is attached to the rear end of the supporting rod 13, and a pressing piece 15 having a pressing surface H is attached to the entire front side surface of the cutter 14 with a cutting margin height so as to be detachably attached by a bolt. There is. Further, the supporting rod 13 is normally held in a solid line state by an appropriate supporting means such as a spring, and when the lever portion 13b formed at the front end portion is lifted and rotated in the arrow direction, the pressing device 12 moves downward and is in a dotted line state. It is configured to have a pressing posture.

Further, the lifting operation of the pressing device 12 and the cutter 14 can be operated by the operation lever 13C provided in the driver's seat 3 so that the support bar 13 is rotated by the driving force of the transmission case 6. It will be convenient. Next, a method of operating the multi-transplanter of the present invention will be described.
First, in a state where the transplantation section C is lifted up, the sheet S of the sheet roll s installed on the support section 9 is fed out so as to reach below the preceding roll 10a, and then the transplantation section C is lowered to the rice field to run the machine body 1. Let Then, the sheet S is pressed and sandwiched between the roller float 10 and the rice field and fed out, and the starting end portion thereof reaches immediately below the pressing device 12.

At this time, when the lever portion 13b of the pressing device 12 is operated in the direction of the arrow to move the pressing piece 15 downward, the pressing surface of the pressing piece 15 presses the starting end portion of the sheet S over the entire width, and the pressing surface is directed to the rice field. Push in and fix in the embedded state. Therefore, since the starting end portion of the seat S is firmly fixed to the paddy surface in the early stage of laying on the rice field, the seat S can be laid satisfactorily in the state where there is no deviation of the sheet S at the beginning of traveling of the machine body 1.
By fixing the starting end portion of the sheet S to the rice field in this manner, the sheet S is sufficiently brought into close contact with the rice field in the initial stage of laying and is quickly moistened. The planting work carried out through the plant can be favorably performed without damage to the seedlings.

Further, when the pressing piece 15 is integrally attached to the cutter 14 which is moved up and down, the structure of the mounting portion is also used so that the pressing piece 15 can be manufactured easily and with high rigidity, and at the same time, the pressing piece 15 can be manufactured at a low cost. When pressing near the start end of the sheet S, the cutting edge of the cutter 14 acts so as to embed the start end of the sheet S deeper behind the pressing piece 15 without completely cutting the sheet S.

At this time, as shown in FIGS. 3 and 4, the sheet S laid on the roller float 10 is first fed out by the preceding roller 10a having a smooth surface so as to extend the wrinkle of its full width and evenly on the ground. After being pressed, the part is contacted with the paddy field and is re-rolled by the succeeding trailing roll 10b in a state of being slightly wet, and the pressing member used as the ring body 11 further presses the planting locus to form the planting surface R. It will be laid while forming.

Therefore, the sheet S of the planted portion is surely brought into close contact with a field scene such as a paddy field, and for example, the sheet S made of paper is swelled and softened more reliably and swiftly even on a rice field where water filling is insufficient. Therefore, the transplanting nail 8 allows the planting surface R to be easily punched out without damaging the seedlings while gripping the seedlings, thereby enabling efficient multi-transplanting work. When strongly pressed by the pressing member, it is depressed like a concave groove, and the portion of this depression forms the planting surface R, so that further effects can be expected.

When the sheet S is a vinyl sheet, a water retaining effect can be produced in which water is stored in the concave planting locus line formed by the ring body 11, and this portion is in close contact with the ground and peeled off by wind or the like. Since this can be done without adverse effects such as vibration, it is possible to favorably grow the crop.

[0021]

Since the present invention is configured as described above, the sheet S that is unwound from the supporting portion 9 and laid in the field scene is strongly applied to the field scene in front of the transplant nail 8 by the pressing member composed of the roller float 10. Since the paper sheet S is pressed so as to come into close contact with it, the paper sheet S can be quickly moistened and the transplanted nails 8 can be efficiently planted with no damage to planting of transplanted objects such as seedlings.
