In addition , since the liquid spraying means 7 for spraying the liquid is provided on the cloth multi M, the cloth multi M laid immediately includes water and sticks to the paddy field, making it difficult for the cloth multi M to be swept away by the wind. The work for correcting the laying state of the multi-M is reduced, whereby the work for laying the cloth multi-M can be performed more efficiently and accurately.

  The purpose of providing a cloth multi laying machine for laying cloth mulch made of cloth such as non-woven fabric on the paddy surface was realized by allowing cloth mulch to be laid efficiently.

  A cloth multi-laying machine according to an embodiment of the present invention will be described below.

  This cloth multi-laying machine has a core inserted into the center of a cloth roll R in which seeds (seeds) S are sown at appropriate intervals between two cloth multi-M made of a cloth such as a non-woven cloth. A cloth roll support device 2 that rotatably supports both ends of the rod CS on the left and right sides is attached to the rear portion of the self-propelled vehicle body 1 through a lifting device 3 so that the cloth roll R has a lower end on the paddy surface. The fabric multi-M is mounted from the outer peripheral side of the fabric roll R by moving forward while the fabric roll R is in contact with the paddy surface and rolling up the fabric roll R. The cloth multi-M is laid out on the paddy surface by drawing it back. In addition, when laying a cloth roll R in which a single cloth multi M is wound on a paddy field, seeds (seeds) S are sown on the paddy field in front of the cloth multi laying position of the cloth multi laying machine. It shall be equipped with a sowing device.

  The self-propelled vehicle body 1 is a traveling vehicle body capable of traveling in a paddy field, and is equipped with an engine for self-propelling the aircraft, and is driven for traveling by front and rear wheels 9, 9, 10, 10 or left and right crawlers that rotate. A rotating body is provided. The example shown in the figure is a riding type four-wheeled vehicle body mounted on a riding type rice transplanter. Step 11 for the operator to board on the vehicle body, a seat 12 for the piloted driver to sit, The steering wheel 13 which steers the front wheels 9 and 9 for a person to steer, and the operation apparatus 14 which carries out the raising / lowering drive operation of the raising / lowering apparatus 3 are provided.

  The elevating device 3 is an elevating link mechanism provided so as to drive the link mechanism 3b up and down by a driving device such as a hydraulic cylinder 3a. A connecting shaft 15 whose axis is directed in the front-rear direction is provided at the rear portion of the lifting device 3, and the cloth roll support device 2 is mounted via the connecting shaft 15 so as to be movable in the left-right direction. Accordingly, the cloth roll support device 2 can be raised and lowered by the operation of the operator's operation device 14, whereby the cloth roll R can be raised and lowered between a state where its lower end is grounded on the paddy surface and a state where it floats. . Further, when the cloth roll R is grounded to the paddy surface, if the paddy surface is tilted to the left or right or the self-propelled vehicle body 1 is tilted to the left or right, the cloth roll support device 2 rolls to the left and right around the connecting shaft 15. The right and left sides of the lower end of the fabric roll R are grounded.

  The cloth roll support device 2 is a U-shaped support in a plan view that rotatably supports both ends of a core rod CS inserted into the center of a cloth roll R in which a cloth multi M made of cloth such as nonwoven fabric is wound in a roll shape. A frame 16 is provided. Bearing portions 16b and 16b are provided at the rear end portions of the left and right frame portions 16a and 16a extending rearward on the left and right sides of the support frame 16 so that the left and right ends of the core rod CS are detachable and can be rotatably supported when mounted. . Accordingly, when starting the laying operation, the cloth roll support device 2 is loaded with the cloth roll R into which the core rod CS is inserted at the center by the operator. Is removed, and the core rod CS is inserted into a new cloth roll R and is mounted again, and the laying operation is continued.

  In the illustrated example, the cloth roll R is mounted so that the cloth multi M on the outer peripheral side is fed out from the front side of the cloth roll R. When mounted in this manner, the cloth multi-M can be laid on the paddy surface up to the lower part of the cloth roll R, so that the laying range of the cloth multi-M by this laying machine can be expanded and the work of laying the cloth multi-M can be performed more efficiently. .

  Further, in the illustrated example, the front stroke cloth multi-pressing means 17 that presses the adjacent left and right end portions of the cloth multi M laid in the previous laying work travel from the top, the cloth multi M fed from the cloth roll R is the paddy surface. It is provided on the front side of the place where it is grounded. This makes it difficult for the wind to enter from the left and right end portions of the cloth multi-M, making it difficult to turn it over, so that the laying work of the cloth multi-M can be performed more efficiently and appropriately. Further, the front stroke cloth multi-pressing means 17 equalizes the travel trace (wheel trace) of the self-propelled vehicle body 1. As a result, the cloth mulch M comes in closer contact with the paddy surface, and the roots extended from the seed pods extend to the ground with certainty, thereby enabling favorable cultivation.

  Therefore, this cloth multi-laying machine simply moves the self-propelled vehicle body 1 forward by lowering the cloth roll R to the state where it touches the paddy surface by the lifting device 3, and the cloth roll R rolls on the paddy surface. Since the cloth multi M is drawn out from the outer peripheral side of the cloth roll R to the rear of the machine body, the laying work of the cloth multi M can be started quickly and the laying work can be performed quickly. When the machine is swiveled near the paddy field, the fabric roll R is lifted from the paddy surface by the lifting device 3, so that the roll is not disturbed by dragging the cloth roll R on the paddy surface when the machine is swung. Laying work can be resumed quickly and accurately. Therefore, the laying work of the cloth multi-M can be performed efficiently and accurately. As shown in the example, when traveling back and forth in a paddy field so that there is no gap between the cloth multi M laid in the current process and the cloth multi M laid in the previous process, the work travel in the previous process is performed. The cloth multi M is laid in such a manner that the left and right end parts of the cloth multi M laid by the current work travel are overlapped on the adjacent left and right one end parts of the cloth multi M laid in the above.

  In addition, this cloth multi-laying machine is provided with a cutting device 4 that cuts the cloth multi-M fed from the cloth roll R left and right. The cutting device 4 is configured to cut the cloth multi M fed below the cloth roll R below the cloth roll R. Furthermore, when the cloth roll R is levitated from the paddy surface, the cloth multi M is cut between the outer periphery of the cloth roll R and the ground contact with the paddy surface. Further, the cutting device 4 includes a cutting blade 5 that is long on the left and right for cutting the cloth multi M, and a multi support member 6 that supports the cloth multi near the cutting portion, and the cutting blade 5 and the multi support member 6 are provided. The cloth multi M is provided so as to be movable from the front side and the rear side with respect to the cut position of the cloth multi M.

  In the illustrated example, specifically, the cutting blade 5 includes tip ends of left and right cutting blade support frames 18, 18 provided at the rear end portions of the left and right frame portions 16 a, 16 a of the support frame 16 so as to be rotatable via a horizontal axis. The multi-support member 6 is also attached to the front end portions of the left and right multi-support member support frames 19, 19 provided at the rear end portions of the left and right frame portions 16 a, 16 a of the support frame 16 so as to be rotatable via a horizontal axis The gears 20, 20; 21, 21 having the rotation axes of these frames as rotation centers are attached to the rotation attachment portions of the cutting blade support frames 18, 18 and the multi-support member support frames 19, 19, These gears are provided so as to be engaged with each other on the left and right sides, and the support frames 18, 18; 19, 19 are interlocked so as to rotate in opposite directions. Then, an operation tool 22 for rotating these support frames 18, 18; 19, 19 is provided, and the cutting blade 5 and the multi-support member 6 are moved from the cloth roll R to the paddy surface by the operation of the operation tool 22. , The position away from the cloth multi M fed back and forth, and rotating toward the cloth multi M, the cutting blade support frames 18 and 18 and the respective tip portions of the multi support frames 19 and 19 pass the cloth multi M from the front and rear. It is provided so that it can be moved to a position where it abuts back and forth as if sandwiched. When the leading edges of the cutting blade support frames 18 and 18 and the multi-support frames 19 and 19 come into contact with each other, the engagement projections 6a, 6a,. The cloth multi is supported by being pierced in the vicinity of both upper and lower sides so that the cloth multi is not loosened, and the cutting blade 5 hits the cloth multi M from the opposite side in the front-rear direction to cut the cloth multi M. The cutting blade may be provided on the multi-support member 6 side, or the multi-support member may be provided on the cutting blade side. In this case, the cutting blade is supported by being sandwiched from both sides by an elastic member such as rubber. It is good also as composition to do.

  Therefore, this cloth multi-laying machine can cut the cloth multi-M fed from the cloth roll R left and right by the cutting device 4 when turning the body near the paddy field, so that the movement to the next laying position can be quickly performed. It can be started, and the laying work of the cloth multi-M can be performed more efficiently. Moreover, since the cutting device 4 is configured to cut the cloth multi M fed under the cloth roll R under the cloth roll R, the cutting range can be extended from the rear end of the machine body to the front side, and the laying range can be expanded. Multi-M laying work can be performed more efficiently. When the cutting device 4 lifts the cloth roll R from the paddy surface and cuts the cloth multi M until the cloth roll R contacts the paddy surface from the outer periphery of the cloth roll R, when the next laying operation is resumed after the machine turns The end of the cloth multi-M is immediately grounded, and the laying work can be resumed quickly, so that the cloth multi-M can be laid more efficiently. Further, the cutting device 4 includes a cutting blade 5 that is long on the left and right for cutting the cloth multi M, and a multi support member 6 for supporting the cloth multi near the cutting portion. The cutting blade 5 and the multi support member 6 are connected to the cloth. Since the cloth multi M can be moved from the front side and the rear side of the multi M cutting part so that it can be moved, the cloth multi M can be cut reliably and the next laying work after turning the fuselage Can be resumed quickly, and the laying work of the cloth multi-M can be performed more efficiently.

  When the cloth multi M is cut near the paddy of the paddy field, as shown in FIG. 3, the length corresponding to the area where the cloth multi M is easily laid later in a so-called headland where the aircraft is swung. It is good to cut | disconnect after extending | stretching from the cloth roll R only by that much. Then, after turning the aircraft, simply pulling the unfolded fabric multi M to the heel and deploying it quickly lays the fabric multi M on the paddy paddy surface after turning the aircraft. The laying work of the cloth multi-M can be performed more efficiently. In addition, when the cloth multi M is provided with a mark at every roll winding direction setting interval or a display device for displaying the feed length of the cloth multi M is provided in the cloth multi support device, the cloth multi M that is fed out in the above case is provided. It is easy to cut with a proper length, and laying work can be performed efficiently.

  By the way, when the nonwoven fabric containing the oil component produced from the falling cotton produced in the spinning process is used as the cloth multi M, the cloth multi M hardly contains water and does not easily float on the water surface. For this reason, the cloth multi M laid on the paddy surface may be swept away or turned up by the wind. However, in this example, since the liquid spraying means 7 for spraying a liquid such as water is provided on the cloth multi M, the cloth multi M laid immediately contains water and sticks to the paddy field and is washed away by wind. It becomes difficult to turn over and the work for correcting the laying state of the cloth multi-M is reduced, whereby the work for laying the cloth multi-M can be performed more efficiently and accurately. If the liquid to be sprayed contains a surfactant, even a non-woven fabric containing oil can easily contain water, and the laying operation on the paddy field can be performed more accurately. Further, since the liquid spraying means 7 is configured to spray on the lower surface when the cloth multi M is laid, the cloth multi M laid more quickly contains water and sticks to the paddy field. Multi-M laying work can be performed more efficiently and accurately.

  Further, when the liquid spraying means 7 is sprayed on both left and right ends of the cloth multi M, the left and right ends of the cloth multi M laid immediately include water and stick to the paddy field, so It is difficult for the wind to enter from the end portion, and thus it is difficult to turn over, so that the laying work of the cloth multi-M can be performed more efficiently and accurately. In particular, when the left and right ends of the cloth multi M laid in the current process are laid on the left and right ends of the cloth multi M laid in the previous process, the left and right ends of the cloth multi M that overlaps the upper side. The part is not in direct contact with the paddy field, so it is difficult to contain water. However, by configuring the liquid spraying means 7 to spray the liquid to the left and right ends of the cloth multi-M as described above, the left and right ends of the cloth multi-M overlapped with each other contain water and the wind turns up. As a result, the work of laying the cloth multi-M can be performed more efficiently and accurately.

  Specifically, the liquid spraying means 7 includes a tank that stores a liquid such as water, a pump that pumps the liquid in the tank, nozzles 7a and 7a that eject the liquid pumped by the pump, and a pump from the tank. And a hose for transferring the liquid from the pump to the nozzle.

  Furthermore, this cloth multi-laying machine is provided with pressing means 8 for pressing the left and right ends of the cloth multi-M laid on the paddy surface downward. This makes it difficult for the wind to enter from the left and right end portions of the cloth multi-M, making it difficult to turn it over, so that the laying work of the cloth multi-M can be performed more efficiently and appropriately. This also has a more remarkable effect when the left and right ends of the cloth multi M are laid on top of each other. In the illustrated example, the pressing rollers 24 are rotatably mounted around the horizontal axis at the rear end portions of the left and right mounting members 23, 23, which are attached to the rear end portions of the left and right frame portions 16a, 16a and biased in the direction of rotating downward. 24, and the pressing rollers 24, 24 are configured to press the left and right ends of the cloth multi M laid on the paddy surface downward. In addition, many protrusions 24a ..., 24a ... are provided on the outer peripheral surfaces of the pressing rollers 24, 24, and the cloth multi M is pressed so as to be pushed into the paddy soil, thereby preventing the right and left end portions of the cloth multi M from being turned up. It can be done reliably.

  FIG. 4 shows a cloth multi-laying machine according to another embodiment. In this cloth multi-laying machine, a rice transplanter 25 is mounted on a self-propelled vehicle body 1 via a lifting device 3, and the cloth multi-supporting device having the same configuration as that of the first embodiment is connected to the rice transplanter 25 via a connecting frame 26. 2, the cutting device 4, the pressing means 8 and the like are mounted. Thereby, the cloth multi-laying machine can be configured using the existing riding type rice transplanter, and the existing property can be used effectively. In the configuration shown in FIG. 4, the same configurations as those in the first embodiment are denoted by the same reference numerals.

  FIG. 5 shows a cloth multi-laying machine according to another embodiment. This cloth multi-laying machine has a structure in which the cloth multi-support device 27 is provided so that the position of the cloth roll R can be changed to the left and right. More specifically, the length of the core rod CS ′ of the fabric roll R and the distance between the left and right bearing portions 16b, 16b of the support frame 16 ′ are defined as the left-right width W1 of the fabric roll R and the left-right movement width W2 of the fabric roll R. It is set to be larger than the width obtained by adding. As a result, the cloth multi M is placed so that the left and right ends of the cloth multi M laid in the current work travel are overlapped on the adjacent left and right ends of the cloth multi M laid in the work travel in the previous stroke. When laying, the self-propelled vehicle body 1 can be made to travel away from the cloth multi M laid in the work travel of the previous stroke, and mud pushing (forwarding of wheels, etc.) Mud pushing) makes it difficult for the fabric multi-M laid in the work travel of the previous stroke to lift, and makes it difficult for the wind to enter from the left and right ends of the fabric multi-M, so the fabric multi- M laying work can be performed more efficiently and accurately. In addition, in the structure shown in FIG. 5, the same structure as Example 1 attaches | subjects the same code | symbol.

  6 to 8 show another embodiment of the cloth multi-laying machine. In this cloth multi-laying machine, the cloth multi-supporting device 28 is provided with a cloth multi-supporting device 29 that supports the cloth roll R from below and drives and rotates it. This cloth multi-support device 29 is provided with a U-shaped support frame 30 that is connected to the connecting shaft 15 of the elevating device 3 so as to be rotatable left and right, and the core rod of the cloth roll R is provided on both left and right sides of the support frame 30. When bearings 31 and 31 (in the example shown in the drawing, long holes that are vertically long) are provided to support both ends of the CS so as to be movable up and down, and both ends of the core rod CS of the cloth roll R are set in the bearings 31 and 31 A cloth multi-support rotating device that receives and supports the bottom surface side of the cloth roll R and that can be driven and rotated (in the example shown in the drawing, a wide width that drives and rotates around a plurality of horizontal axes arranged along the outer periphery of the cloth roll R. An endless belt is provided) 32). As shown in FIG. 8, when the cloth roll R is driven and rotated and the cloth multi M is fed out, the outer diameter of the cloth roll R becomes smaller. , 31 is lowered by its own weight, the state where the bottom surface side of the cloth roll R is supported by the cloth multi-support rotating device 32 continues to the end. The cloth multi M driven and rotated by the cloth multi support device 29 is laid while being pressed against the paddy surface by a laying roller 33 provided below. As a result, even if the cloth multi-M such as a non-woven fabric having a low tensile strength is used, the cloth multi-M is hardly broken during the rotation of the cloth roll R during the laying work, and the laying work is less likely to be interrupted. The laying work can be performed more efficiently and accurately. By the way, an openable / closable cover 34 is provided on the upper part of the cloth multi-supporting device 29 so as to cover the cloth roll R that is mounted, so that the cloth roll R gets wet when it rains, and the cloth multi M is broken during laying work. Thus, the laying work is less likely to be interrupted, and this also allows the laying work of the cloth multi-M to be performed more efficiently and accurately. In addition, the above-described first embodiment is intended to prevent the roll R from getting wet and to prevent the cloth multi M from being cut off during the laying operation by providing a cover that covers the outer periphery of the mounted cloth roll R on the cloth multi-supporting device. It is the technique which can be implemented also in ~ 3. In addition, in the structure shown in FIGS. 6-8, the thing of the same structure as Example 1 attaches | subjects the same code | symbol.
