Description

[Detailed description of the invention] The present invention relates to an improvement of a mulch film laying device for agricultural machinery, and provides a mulch film laying device that stretches the mulch film while reinforcing the ridges and reliably covers the ridges. It is something to do with Mr.

When forming ridges into a semicircular shape and applying mulch film,
A newly formed ridge is most likely to collapse near the left and right shoulders, which are the boundaries between the top and the left and right sides. If left alone, the ridges will gradually collapse due to rainfall and irrigation.

In addition, since the mulch film laying equipment has each of the ridge-laying, compacting, and film-stretching members mounted on the equipment frame, the overall length of the mulch film-laying equipment is excessive, and it tends to be heavy, making it difficult to tow it. When a machine, for example, is suspended from a tractor via a work equipment lifting mechanism, the total length including the towing machine becomes long, and the laying device protrudes rearward in a large overhang, so the front part of the towing machine becomes There are problems in that the device tends to float up easily, resulting in a loss of running stability, and that a large amount of power is required to move the device up and down near the end of the ridge.

Therefore, in this invention, at least one drum-shaped pressure roller is installed on each side, which can directly press the left and right shoulders of the semi-cylindrical ridges formed by the ridge board, immediately after the ridge board. The top pressing roller, which is installed behind the pressing roller and is capable of pressing independently with respect to these pressing rollers, presses the top of the ridge through the mulch film that is pressing down on the ridge. The left and right shoulders of the semi-cylindrical ridge, which are most likely to collapse, are directly compressed with the left and right compression rollers to sufficiently compact the shoulders, and then the stretched mulch film is By compressing the top of the ridge from above, compressing the top and stretching the mulch film, the mulch film can closely follow the semicylindrical shape and adhere closely to the surface of the ridge.
In addition, since the pressure roller located immediately after the ridge plate assists the forming action of the ridge plate, the longitudinal length of the ridge plate can be shortened, and the overall length of the laying device can be shortened. This has been improved to ensure stability in the laying work and ease of lifting and lowering operations.

An embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a ridge board, and its length is set to such an extent that it does not cause excessive traction resistance and does not interfere with the formation of the ridge.

2 is a pressure roller, which is provided at least on both sides of the ridge plate 1, and is shaped like a drum.
, 2 are attached so that the shoulders of the ridges can be molded and compressed.

3 is a top pressure roller, which rolls on the top surface of the covered mulch film while partially overlapping the locus of the pressure rollers 2 and 2, so that the mulch film can be spread on the ridge surface while suppressing the top of the ridge. The pressure rollers 2, 2 are attached so that the position can be adjusted independently from the pressure rollers 2, 2.

A film guide 4 is provided diagonally between the pressure rollers 2, 2 and the top pressure roller 3, and guides the mulch film 5 wound into a scroll.

In the figure, numeral 6 is a soil covering disk, 7 is a hem ring made of an elastic material such as urethane, and 8 is a rotary.

Note that the pressure rollers 2, 2 may be an assembly of several rollers.

Next, the operation of this invention will be explained. The soil excavated and transferred by the rotary 8 is shaped by the ridge plate 1 into, for example, a semicylindrical shape.

Next, the ridge formed by the ridge plate 1 is compressed at both shoulders and bands by the transfer of pressure rollers 2, 2 provided immediately after the ridge plate 1, but in this case, the pressure rollers 2 on both sides of the ridge
, 2 presses the shoulder of the ridge toward the center of the ridge, so when the shoulder is crushed, the soil around the shoulder is guided backwards without protruding to the left or right. It also has the ability to form ridges without causing landslides.

The mulch film 5 is guided by the film guide 4 and fed out onto the molded ridge surface hardened in this way, and the top pressure roller 3 provided at the rear of the film guide 4 controls the mulch film 5 to be fed out. The mulch film 5 is pressed against the ridge from above, and the left and right hem portions of the mulch film 5 are well spread along the semicylindrical ridge. This effectively prevents the mulch film 5 from being rolled up due to gusts of wind.

Moreover, the top compression roller 3 also performs the function of compressing the ridge top from above the mulch film 5 while performing the above-described stretching operation of the mulch film 5, but in this case, the shoulders of the ridge are not sufficiently consolidated. Therefore, there is no fear that the ridges will collapse when the mulch film 5 is laid down.

In addition, the compacting roller 2 and the top compacting roller 3 are arranged in a forward and backward manner, and their transfer trajectories partially overlap, so that the ridge is compacted continuously from the shoulder to the top. It becomes extremely strong.

Therefore, according to this devised device, the left and right shoulders of the semicylindrical ridge formed on the ridge board 1 are moved by the drum-shaped pressure roller 2.
, 2, and then the top of the ridge is compressed by the top pressing roller 3 via the stretched mulch film 5, so that the left and right shoulders of the ridge, which are most likely to collapse, are compressed. It is directly and sufficiently compacted by pressing rollers 2, 2,
Subsequently, the top of the ridge is compressed from above the stretched mulch film 5 by an independent top pressing roller 3, and at this time, the mulch film 5 follows the semicircular shape of the ridge well without floating up from the ridge surface. This allows the mulch film 5 to be closely covered with the surface of the ridges during crop growth, without being blown up by the wind, promoting growth and preventing ridges from being blown up by rain or irrigation. It will not collapse.

In addition, since the pressing rollers 2, 2 are provided immediately after the ridge board 1, the ridge forming operation is performed by the ridge forming board 1 and the pressing rollers 2, 2 in cooperation with each other. 1 can be shortened in the longitudinal direction, and the top pressure roller at the rear can also be moved closer to the towing machine.As a result, the overall length of the laying device can be shortened, allowing for easy access from the towing machine to the rear. With this invention, the laying equipment, which is suspended in a large overhang, has become shorter and lighter, improving stability when running, and making it easier to move up and down, allowing quick operation from the beginning to the end of the ridge. It can be done safely.
