Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a method for covering the entire surface of the ridge with soil in order to prevent the band-like film from moving when plowed soil is formed into ridges and the ridges are covered with a band-like film. It is about multi-devices.

[Problems to be solved by the prior art and the invention] Conventional mulching devices of this type include those that drop soil filled in a hopper in advance with a chute, or soil that is lifted up with a bucket conveyor. There are also known devices that cause the soil to fall, and even that scatter or release it through a window provided in the tiller cover. However, special work is required to fill the hopper, and the addition of a bucket conveyor makes the machine heavier and more expensive. Furthermore, if the tilling cover is provided with a window, it will be difficult to guide and guide the soil into the desired furrows.

Furthermore, Japanese Patent Application Laid-Open No. 56-72631 is known, in which a film roll offset to the right or left is provided after the ridge erecting device, and one ridge of the existing ridge and a film roll further away than this is provided. This is a device that covers the entire surface of a field where ridges have been created by wrapping a film over all but one of the newly established ridges. However, in this prior art, soil is not automatically supplied onto the film, so the film is not held down and is therefore unstable. For this reason, farmers had to manually cover the film with soil using a shovel or use barriers to prevent the film from blowing away in the wind. Therefore, problems arise that need to be solved in order to overcome these conventional deficiencies.

[Means for solving problems]

This invention was proposed in view of the above-mentioned problems, and consists of a tilling device for tilling soil to a predetermined width, and a tilling device installed behind the tilling device to plow the soil. A ridge-raiser is used to heave soil into multiple piles, and when the ridge-raiser is placed behind the ridge-raiser and is operated by turning back along the ridges created in the previous process, one pile of the existing ridge and one pile of the newly constructed ridge are used. A film roll that is selectively offset to the right or left so as to hang the multi-film over the ridges except for one furthest from the above-mentioned one ridge, and a presser roller that presses the multi-film against the ground in the valleys of the ridges. and
The plurality of drop ports of the soil lifting device that transfer part of the soil tilled by the tilling device to above the multi-film are moved in the same direction when the film roll and presser roller move to the right or left. A full-surface mulching device characterized by being installed to cause soil to fall into multiple valleys of ridges covered with a film.

[Effect]

With this invention, soil is supplied to all the valleys of the ridge, and the film covering the entire surface of the ridge can be automatically pressed with soil in the valleys.

The shutter shaft 23a is configured to be rotated by the shutter shaft 23a.

When moving the traction machine 1 in the direction of arrow B in FIGS. 1 and 2, or in the direction from the front side to the back side in FIG. Since the support arm 9 is extended to the right side of the movement,
The ridges 5 near the right side of the ridges 5 that are being formed by the ridge tool 4 were formed during the previous ridge-making process (progressing from the back side to the front side in Fig. 3). The ridge 5 on the right side of the figure is covered with the multi-film 15, and the right-hand side of the multi-film 15 to be covered this time overlaps the left-hand side of the multi-film 15 that has been covered in the previous ridge forming process. It will be done.

When moving the traction machine 1 in the direction opposite to the arrow B in FIGS. 1 and 2, that is, in the direction from the back side toward the page in FIG.
Loosen the support arm 9, rotate the support arm 9 180° to the left in FIG. The film roll 16, the spreading pressure roller 19... and the hopper 2 are fixed so as to extend to the left.

The ridge 5 on the left side, which is being moved, will be covered with the multi-film 15 during the next ridge-raising process in the direction of the arrow B, and the tail wheels 7, 7 will step on the multi-film 15. It will always roll in the uncultivated soil or the ridges and grooves 20 before being covered. Further, the soil that is being collected in the hopper 21 falls onto the multi-film 15 above the ridges 20 from the drop openings 22a, 22b, which are intermittently opened and closed by the shutter 23. Also, during the furrowing process from the back side to the front side in Figure 3, the furrow groove 20 on the far left side of the figure is covered with soil, but the soil is located above this furrow groove 20. Since the discharge area of the drop port 22a is made small as described above, the amount of soil that falls in one reciprocating stroke is approximately the same as the soil that comes from the central drop port 22b, which is covered with soil in only one stroke. , the soil in the hopper 21 is used without wastage.

As explained in detail in the above-mentioned embodiment, this invention has the following features:
A part of the soil tilled by the tillage device 2 is moved left and right and is automatically applied to the mulch film 15 placed on the ridges 5 in the valley area, so that the work of covering the mulch film 15 with soil is not done manually. This can now be done completely automatically without the need for In other words, soil is applied to all the valleys of the ridges, and the mulch film covering the entire surface of the ridges is automatically pressed down with soil in the valleys.
