In the figure, a cylindrical body 37 is provided at the tip of each stay 31, 31 of the left and right sponge wheels 27, 27 so as to project outward, and the rear end of the parallel link 38 is attached to each cylinder 37. The amount of protrusion to the side is adjustable, and it is attached in the forward direction of the multi-film laying machine 10, and a gauge wheel 39 is attached to the front end of the parallel link 38. An arm piece 40 is attached from the parallel link 38 in parallel with the parallel link 38, and a brush 33a and a wind outlet 35a are attached to the arm piece 40. Thus, the brush 33a and the air outlet 35a can be arranged as shown in the embodiment of FIG. In that case, it has the same function as the embodiment of FIG. Thus, in the present embodiment, the brush 33a and the air outlet 35a.
Is supported by a gauge wheel 39 through a parallel link 38, and the gauge wheel 39 rolls on the mulch film 20 laid on the soil surface flattened in the previous step. There is little movement. Therefore, the brush 33
The height of the a and the air outlet 35a is regulated by the gauge wheel 39, and is not affected by the vertical movement due to the ups and downs of the multi-film laying machine 10 when the multi-film laying machine 10 is moved forward.
It is possible to perform the cleaning action of mud on the ground.

In FIG. 7, when the air is blown from the air outlet 35 or 35a, the wind direction is switched in association with the offset operation of the multi-film feeding unit 19. In the figure, the side beam 18 is a toolbar 16 shown in FIG.
It is configured so that it can be offset left and right with respect to. That is, one end of the link pieces 42, 42 is pivotally attached to the rear end of the support pieces 41, 41 projecting rearward from both sides of the tool bar 16, and the other end of the link pieces 42, 42 is further attached. While pivoting the side beams 18 in parallel with each other,
The connecting rod 42a is pivotally attached to one end of the link pieces 42, 42 to form a parallel link mechanism. Thus, the link piece 4
Since one end portions of the link pieces 42 and 42 are pivotally attached to the support pieces 41 and 41 fixed to the toolbar 16 as described above, this pivot point does not swing, and the link pieces 42 and 42 are rotated right and left. The side beam 18 is laterally offset by the movement. Therefore, the feeding portion 19 of the multi-film 20 attached to the side beam 18 and the adhesive tape 3 are attached.
The rolls 29 and the like of 0 are offset to the side opposite to the mulch film laying in the previous step, and the mulch film laying operation in the subsequent step is performed.

Further, switching stays 43, 43 are provided so as to project above a substantially central portion of the side beam 18 with a predetermined interval, and further, above the side beam 18 and project from the toolbar 16. An electric fan 36 is mounted on an installed support member (not shown) or the like, and wind generated by the electric fan 36 is placed near the lower portions of the rolls 29, 29 of the left and right adhesive tapes 30, 30. When the air is blown to any of the air outlets 35, 35 or 35a, 35a provided, the electric fan 36 is blown so that the roll of the mulch film 20 is blown to the air outlet 35 or 35a on the offset side. A wind direction switching shutter 46 is disposed in the air distribution pipe 45 continuously provided in the air distribution pipe 45, and the lower end of the wind direction switching shutter 46 is inserted between the switching stays 43, 43,

Of the connected flexible pipes 36a, 36a, the air is sent to the wind outlet 35 on the side that is connected and offset or the flexible pipe 36a on the side of 35a.

Thus, the wind generated by the electric fan 36 is offset from the air outlets 35, 35.
Since all of the air is blown to a, it is possible to obtain a strong air volume, and since the above-mentioned wind direction is switched in conjunction with the offset operation of the multi-film feeding unit 19, the switching operation will not be forgotten.

Further, according to the present invention, the air outlet 35 or 35a for the air sent by the electric fan 36 or the like is formed in a small size which is substantially the same as or wider than the width of the adhesive tape 30 and is thin.
Alternatively, if it is formed in an elliptical shape and is arranged in front of the adhesive surface of the adhesive tape 30 described above, the wind generated by the electric fan 36 is stronger than the air outlet 35 or 35a. Will be. In such a case, it should be possible to sufficiently blow off the mud and the like on the upper surface of the mulch film 20 laid in the previous step by using only the air outlet 35 or 35a as a cleaning tool.

Furthermore, the brush 33 or 33a is formed to have substantially the same width as the adhesive tape 30 or a wider width as described above, and the outer portion of the brush 33 or 33a is laid with a multi-film from the inner portion. In the case where the brush 33 or 33a is installed so as to be inclined so as to precede the traveling direction of the machine 10, the outer portion of the brush 33 or 33a advances ahead of the inner portion, so that a large amount of mud blown off by the rotary working machine 11 is removed. It can be swept toward the soil that is cultivated in a later step, and the remaining fine powdery dust and the like can be blown off by the air outlet 35 or 35a, and the adhesive work with the adhesive tape 30 described above is extremely effective. You can do it.

The present invention can be modified in various ways without departing from the spirit of the present invention, and it goes without saying that the present invention extends to such modifications.
