2. Description of the Related Art In the field of rice cultivation, by removing only seedlings and covering the rice field with a sheet of vinyl film or the like, weeds are prevented from growing and the problem of environmental pollution caused by herbicides is solved. Recently, the multi-paddy rice cultivation method has been attracting attention because simplification and labor saving of cultivation management after planting can be achieved.

In the field of upland crops, particularly in the cultivation of fresh vegetables such as lettuce, Chinese cabbage, and cabbage, the heat retention of the field is enhanced to improve the germination and survival of the seeds and to prevent the soil from jumping during rainfall. In order to prevent the occurrence of weeds, mulch cultivation in which the soil surface is covered with a sheet has become widespread.

[0004] In general, a transplanting machine for multi-cultivation (multi-transplanting machine) as described above generally has a planting section connected to the rear of a traveling machine so as to be able to move up and down, and a roll-shaped sheet suspended horizontally in a roll storage section. Are sequentially fed backward, and the seedlings are planted from the sheets covered with the planting rods while covering the field scene.

In such a multi-transplanter, the sheet covered in the field scene is brought into close contact with the ground surface to increase the planting accuracy, and the planting section is designed so that the sheet is not blown off by the wind or lifted off the ground surface. Requires a pressure-reducing means such as a pressure-reducing roll for bringing the sheet covered in the field scene into close contact with the ground surface. In particular, since the left and right end portions of the sheet are easily turned up, it has been proposed to arrange pressure suppression means such as a roll on both the left and right sides of the planting portion.

[0006]

However, simply providing the pressure-reducing means on both the left and right sides of the planting portion may cause inconvenience during the actual planting operation. In other words, the streaking work performed at the time of ridge planting, etc. (two or three strips on the left or right side end side where the stalk is wrapped so that all the strips can be planted in the final stage of planting at the ridge. At the time of planting and sheet feeding, the customary work of stopping the planting in the immediately preceding process), the ground surface on one of the left and right blocking sides (the side where sheet feeding and seedling planting were stopped) (planting in the next process) Since the sheet is not laid in the area where the sheet is laid, the crushing means travels while diving into the soil and not only has the possibility of grooving the ground surface with a flat corner, but also the submerging part in the soil may be straw waste or weeds. It is also conceivable that dragging of the foreign substances may adversely affect each part of the planting.

A switching means (a hook in the embodiment) 33 is integrally attached to the support frame 29. By selectively engaging and disengaging the left and right hooks 33 with respect to the support frame 29, the left and right pressure reduction means 2 are provided.
8 can be independently switched between a working posture in which the side end of the sheet b laid on the ground surface is pressed and urged, and a non-working posture in which the sheet b is rotated and retracted upward from the surface of the sheet b.

FIG. 3 shows an arm 31 for attaching the pressure-reducing means 28 which is connected to left and right locking levers 19 via wires 34, respectively. When the locking lever 19 is tilted toward the locking side (upward in the embodiment), the arm 31 on the corresponding side (the locking side) is pulled by the wire 34, so that the arm 31 and the pressure-reducing means 28 are centered on the support shaft 30. The arm 31 and the pressure-reducing means 28 are pivotally displaced from the working posture (grounding posture) to the non-working posture (upward withdrawal posture) against the biasing spring 32 (by locking the lever 19 to the locking side). When the locking lever 19 is returned to the original position (normal position), the pressure-reducing means 28 is automatically returned to the operating position by the urging spring 32.

Numeral 35 denotes an arc-shaped paddle surface inclination detecting sensor linked to a tension meter 36. The paddle surface inclination detection sensor 35 and the potentiometer are positioned between the pressure-reducing means 28 and the outermost planting rod 12, and are positioned right and left. Are arranged separately from each other, thereby detecting the degree of left-right inclination of the planting portion P and controlling the planting portion P to be in an appropriate planting posture via a control unit (not shown). It has become.

In the above-described configuration, the planting operation is started in a state in which the sheet end is pulled out from the roll storage section 20 backward, and the sheet free end side is fixed to the rice paddle between the roller float 13 and the pressure-reducing roller 28 and the rice paddle. Then, as the machine body 1 advances, the sheet b is sequentially fed out from the roll storage unit 20, rolled by the roller float 13 and brought into close contact with the rice field, and then the seedlings from above the sheet b are fed by the subsequent planting rod 12. Planted.

At the time of the stripping work, the roll (b) having a short length (narrow width) is replaced in the roll storage unit 20, and the corresponding stripping lever 19 is pulled up to stop the planting of the strip and the feeding of the seedling. However, at the time of this fixing, the arm 31 and the pressure-reducing means 28 on the left or right side to be fixed are pulled upward to attach the hook 33 to the support frame 2.
9 is engaged. As a result, the pressure-reducing means 28 on the side where the sheet b is not laid on the rice field surface (retaining side) is held in a non-operating position in which the sheet b is rotated upward and retreated from the rice field surface, so that the pressure-reducing means 28 on the retaining side is planted in the next step. There is no danger of ditching on the paddy field and scratching or accumulating and dragging foreign substances such as straw chips and weeds in the pressure suppression means 28. For this reason, it is possible to prevent the suppression means 28 from roughening the flattened flat rice field or adversely affecting the rice field inclination detection sensor 35.

Further, an arm 31 for mounting the pressure reduction means 28 is provided.
To the left and right corresponding locking levers 1 via wires 34, respectively.
9, the right or left locking lever 19 corresponding to the non-planting strip is set on the locking side (upward in the embodiment).
Since the pressure-reducing means 28 can be switched from the working posture to the non-working posture only by performing the tilting operation, the operability can be greatly improved without the trouble of hooking and removing the hook 33 each time.

In the present invention, since the recycled paper is used as the sheet b, the recycled paper dissolves and dissolves in the mud 40 to 50 days after transplantation, so that the conventional cultivation technique can be used. Therefore, the troublesome work of sheet recovery is not required, and labor saving of mulch cultivation and reuse of natural resources are achieved.
