置も提供されている。Conventional technology In the cultivation of lettuce, Chinese cabbage, cabbage, etc., the soil surface is cleaned to improve the moisture retention of the field to improve the germination of seeds and the establishment of seedlings, and to prevent the soil from flying up during rain and the growth of weeds. Mulch cultivation in which the soil is covered with a sheet of vinyl or the like is widely used, and mulching devices are also provided that use shaping plates to shape the soil into ridges and at the same time cover the surface of the soil after the ridge formation with a sheet.

ものも見受けられる。 This mulching device was designed to be used in conjunction with a rotary tillage device usually attached to a tractor, etc. Initially, soil was applied to the side edges of each row of the sheet to prevent the sheet from turning over. Recently, a method has been seen in which a sheet is covered across multiple ridges, and soil transported by a conveyor is placed on the sheet here and there.

ている。 However, the fixed sheet type that covers multiple ridges by placing soil requires equipment such as a device for scooping soil, a conveyor, and a soil guide tube, making the device itself complicated and large-scale, and the soil is not deposited on the sheet. Because they are exposed, they have disadvantages such as being less effective in preventing weeds from growing and preventing soil from splashing due to rain. Therefore, after shaping the soil into ridges using a shaping plate and inserting the side edge side (hem) of the sheet into each groove formed between the ridges, each groove is pressed and collapsed with each compression wheel, and the sheet is placed in the field. A multiple ridge type mulch device that is fixed to the ground has also been proposed.

In some places, there were problems such as sheets being turned over by the wind.

In the multi-ridge mulch device, in which the sheet is fixed to the field by collapsing under pressure, each pressing ring that presses the groove after the sheet is inserted is supported by an inner member having a stopper for regulating upward movement, and The inners are fitted to the outer attached to the frame so that they can move up and down independently via compression bullets installed in each outer, and in the working state, the stopper comes into contact with the outer and the upward movement of each suppression wheel is carried out. A waterproof cap integrally connected to the inner is fitted on the upper part of the outer so as to be able to move vertically and slide freely. This is an attempt to solve the above problems.

By fixing the tip of the rolled sheet loaded in the mulch device to the ridge starting end, the sheet is fed out along the ridge. After that, the hem side of the sheet is inserted into the groove by a subsequent penetrating wheel, and the upper surface of the groove into which the sheet has been inserted is further compressed by a pressing wheel, so that the sheet side end side is clamped and fixed in the soil. At this time, each suppression ring freely lowers and contacts the ground depending on the height of the furrow or the density of the ground soil due to the elastic force of the compression bullet, so the pressing force of each suppression ring is always optimal. held in state.

Ｄ参照）。 In the above structure, when starting work now, the free end side of the sheet 13 pulled out rearward is fixed to one end of the field by an appropriate method. Next, when the machine is moved forward and work begins, the rotary tilling device 1
The tilled soil is shaped into ridges by the shaping plate 4, and at the same time, grooves a are formed between the ridges by the groove cutting blade 9.
In addition, the sheet 13 that is fed out rearward as the aircraft moves forward has multiple ridges (in this example, three ridges) on the upper surface of the ridge.
The lap part at the sheet side end is guided between the ridges by the tension wheel 15 and is pressed into the groove a by the subsequent penetration wheel 10, and then the compression wheel 11 covers the sheet. Groove a from above 13
The side wall of the seat trap is pushed down and the seat trap section is firmly clamped and fixed without exposing the soil (see Figures 16A to 16D).

保持される。 By the way, in a structure in which the suppression wheels 11 are integrally connected, it is difficult for all the wheels to contact the groove a section at the same time, but in the present invention, each inner 15a that pivotally supports the suppression ring 11 and Compression bullets 21 are interposed between the outer 16 in which the suppressing wheels 15a are fitted, each of which always urges the suppressing wheels 11 in the direction of contact with the ground, and each of the four suppressing wheels 11 is an independent suspension system that freely moves by the dimension H. Therefore, each ring is always in contact with the ground without any uneven lifting of some of the suppressing wheels, and uniform suppressing action is performed. Moreover, when the suppressing part comes to soft ground during work, the suppressing ring 11 is moved downward by the compression bullet 21, so that optimal suppressing is always performed.
Similarly, even if the hardness (density) of the soil below each pressure wheel 11 differs depending on the tillage state in the previous process, each pressure wheel 11
The compressor bomb 2 corresponds to the density of the soil to be compressed.
1, the pressing force of each pressing wheel 11 can be maintained at an optimal level regardless of the soil quality of the field.

ながら、シート１３の固定を一層確実に行うこと
ができる。 By the way, if the suppression wheel 11 is simply supported via the compression bullets 11 so as to be able to move up and down, it will not work if the soil below the suppression wheel 11 is hard enough to overcome the spring pressure of the compression bullets 11. In this case, the compression ring 11 escapes upward against the spring pressure, resulting in insufficient pressing force. In this case, in this embodiment, the collar portion (stopper) 15'a
Since the upward movement of the suppressing ring 11 is restricted by coming into contact with the lower end, the suppressing ring 11 will not escape upward against the compression bomb 12, so the pressing force by the suppressing ring 11 will be insufficient. This allows the sheet 13 to be fixed more reliably while simultaneously covering multiple ridges of the sheet 13.

することができる。 Now, all four restraining wheels 11 must run directly above their respective grooves a parallel to the direction of travel and while maintaining a constant height from the ground, but these adjustments can be made using the elongated holes 22a and push bolts 26. Toolbar 17
This is done by adjusting the spacer back and forth, adjusting it left and right using the guide 23 and push bolt 27, and vertically adjusting it by inserting or removing the spacer 25 or changing the thickness. The penetrating wheel 10 and the tension wheel 12 can be adjusted in the same way, so that the tension wheel 12 will not break the ridge (FIG. 17A), the penetrating wheel 10 will damage the sheet 13 (FIG. 17B), and the groove will not be damaged. To eliminate inconveniences such as the cutting blade 9 and the penetration ring 10 being too far apart and destroying the groove (Fig. 18), or the penetration ring 10 being too high and the sheet 13 not being properly penetrated (Fig. 19). be able to.

る効果がある。Effects of the invention As mentioned above, the present invention forms the soil into ridges using a shaping plate, inserts the side edges of a sheet such as a vinyl film into the grooves formed between the ridges, and then presses the grooves with a pressure ring. In a multi-ridge mulch device that collapses and fixes the sheet to the field,
Each compression ring that presses the groove after the sheet is inserted is supported by an inner member having a stopper for regulating upward movement, and the inner member is independently connected to an outer member attached to a frame via a compression bullet installed inside the outer member. The stoppers are fitted so as to be movable up and down, and in the working state, the stopper comes into contact with the outer to prevent the upward movement of each suppressing wheel, and only the downward movement due to the elastic force of the compression ammunition is permitted. However, since a waterproof cap integrally connected with the inner is fitted onto the upper part of the outer so as to be able to move up and down, it is possible to simultaneously coat multiple ridges in one process, greatly improving work efficiency. Although it is a multi-furrow type multi-layer device, even if the hardness (density) of the soil under each suppression ring is different, each suppression ring can independently compress the soil according to the density etc. of the soil it presses. Since it moves downward, the pressing force of each compression wheel can be optimally maintained regardless of the soil quality of the field, and even if the soil of the field is hard, the compression wheels will resist the compression bullet and escape upwards. This prevents the pressing force from becoming insufficient, making it possible to secure the sheet over multiple ridges even more reliably.Furthermore, the compressor is housed inside the outer shell and is protected by a waterproof cap. This has the effect of preventing muddy water from adhering to it and rusting, significantly increasing the durability of the compression bullet.
