When the horizontal rod 32 is pulled out to the rear, the intermediate bracket 30 will move around the rotation center axis 31.
Since the horizontal rod 32 and the film roll 34 can rotate relative to each other, when the earth lifting device 17 is held at the respective positions as shown in FIGS. 2 and 5, the film roll 34 also rotates. It will be held near the left side or near the right side of the traction machine 1, respectively.

The soil lifting device 17 has a pulley 38 on the upper part of the frames 18, 18, and a spiral body 39 on the lower part.
A belt 41, on which the lugs 40... or bucket belts are arranged, is wound around the pulley 38 and the helical body 39, and the pulley 38 is moved in the direction of the arrow in FIG. 1 by a hydraulic motor 42. The hopper 2 rotates and lifts the soil near the furrow B with each lug 40.

A handle 47 with a fixed base is suspended by a spring 48 to form a dropping mechanism 49, and the soil that falls into the hopper 23 from the top of the soil lifting conveyor 17 is transferred to the compartments R ₁ , R ₂ .R. When the soil reaches a predetermined weight, the shutter 45 collapses against the spring 48 as shown by the two-dot chain line in _FIG . ₁ ,
Soil is distributed and flows from R ₂ and R ₃ to the earth removal parts 27a, 27b, 27c, and
The structure is such that the mulch film C near each of the ridges B ₀ , B, and B is covered with soil D from the lower part of the ridge 7c. Furthermore, the partition plates 43 and 44 do not necessarily have to be fixed. In such a case, earth removal section 2
The amount of soil flowing into 7a, 27b, and 27c can also be adjusted.

Then, the ridge making and film laying work is carried out using the ridge grooves of ridge A ₀ that have already been formed in the previous process as shown in Figure 2.

The dropping mechanism 49 may be a rotary valve, for example, in addition to the above-described rotational movement of the shutter 45, and other mechanisms having similar functions may be used.

Further, the number of compartments R ₁ , R _{2 .} . . may be three or more, and the soil lifting device 17 may be a screw, for example.

Furthermore, the structure of the film laying part 28 and the means for fixing it at each position may be of various types other than those shown in the drawings, such as a method of inserting and removing pins.

The covering soil distribution device in the multi-film laying device according to the present invention is constructed as described above, and the soil flowing into the hopper 23 from the soil lifting device 17 is divided into compartments R ₁ , R ₂ , and R _{3 .} By the operation of the dropping mechanism 49, the soil distribution parts 27a, 27b...
In this way, the distribution operation is performed reliably and a predetermined amount of soil is covered.

As mentioned above, since soil is covered intermittently, it is difficult to be washed away by rainwater, etc.
In addition, weeds do not grow, and good soil covering can be done with less effort. In detail, since the soil can be automatically supplied onto the mulch film that covers the entire surface of the field, it is possible to supply the soil to three furrows with a single soil lifting conveyor, and the Since the pressing soil is taken from the front of the central ridge, there is no problem with the shape of the ridge. Furthermore, since soil is dropped intermittently,
The soil collects and holds down the mulch film, reducing runoff from rain on slopes. In addition, since the shutter is provided at the top of the chute, the soil collects and flows well within the chute, making it possible to lower the soil lifting conveyor and make the slope of the chute gentler. The whole thing can be made compact. In particular, as shown in the side view of Figure 1, this mulch device protrudes significantly rearward from the tilling device and is also tall, making it unstable to drive over ridges and other operations. Lifting is difficult with the lifting force, but with this invention, these problems are solved because it is compact.
