Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a farmland covering sheet for cultivating crops, which covers the farmland to heat and moisturize the ground around the crop and prevent weeds from growing in order to cultivate crops such as straw. The present invention relates to an apparatus for making a hole for growing above.
[0002]
[Prior art]
Until now, in order to cultivate crops such as straw, we cover the vines of farmland to keep the ground around the crops warm and moisturized, and to prevent the growth of weeds In order to allow the crops to grow on the sheet, the portion directly above the seedlings of the crop is cut open.
[0003]
Usually, the hole drilling work is performed by picking and cutting with a finger or a nail a portion swelled by a crop after the sheet is laid. This drilling work was very hard work because it was a work that bent or crouched to the middle.
Therefore, an apparatus has been proposed that attempts to stop the drilling work by a person who is such a hard work and perform it mechanically.
[0004]
For example, until now, in Japanese Utility Model Laid-Open No. 63-45464, a gauge cutter that rolls a disk with a cutting blade from above the sheet, and in Japanese Utility Model Laid-Open No. 2-127152, the sheet is rolled in a state before being laid on farmland. A punching machine that pierces a cone blade and winds it up, and further, JP-A-8-140696 proposes a device that attaches to a farm tractor and opens a hole while laying a roll sheet on the farm ground. .

As shown in FIG. 1, the gap drilling device for a farmland covering sheet for crop cultivation of the present invention has two long pipes in the rear and two short pipes in parallel with a gap in the front. The support base 1 is assembled by standing and connecting these pipes in parallel.
Two long pipes at the rear are provided with bearings 2 and 2 that are open at the top so that the roll support shaft 3 inserted into the core hole 5 of the sheet roll 4 can be removed.
[0012]
The two short pipes on the front are provided with a slide support shaft 16 at a distance from the roll support shaft 3, and a slide moving shaft 17 in which an upright support shaft 18 is fixed upright on the slide support shaft 16 slides. A disk moving means 15 is provided so that it can move.
Then, the disk support shaft 6 is fixed to the upright support shaft 18 so as to be parallel to the roll support shaft 3.
[0013]
The disk support shaft 6 has a disk 8 on which an anti-slip surface 11 is formed by winding a rubber band having an uneven surface on the outer periphery, and cutter blades 9 are projected at a plurality of intervals in the radial direction. A shaft is attached so as to be freely rotated by a rotating shaft 10 provided on the shaft.
The interval between the roll support shaft 3 and the slide support shaft 16 is an interval at which the surface of the roll can rotate without contacting the tip of the cutter blade 9 and the sheet can be pulled out smoothly.
[0014]
Then, a tension bar 13 is installed between the roll support shaft 3 and the rotary shaft 10 of the disk 8 on the support base 1 to pull down the sheet S downward.
[0015]
The number of the disks 8 can be one according to the number of rows of crops, but a plurality can be provided. (FIGS. 1 and 2 show a mode in which two pieces are provided, and FIG.
[0016]
Further, a blade adjusting means 14 is provided on the disk surface 8a of the disk 8 so that the cutter blade 9 can be adjusted in and out and / or detachable .
As shown in FIG. 2, the blade adjusting means 14 can be configured such that a replaceable blade type cutter can be attached to and detached from the board surface 8a by screwing.
[0017]
[Action]
Since the present invention has the above-mentioned configuration, as shown in FIG. 4, when the sheet S of the sheet roll 4 is pulled out, the cutter blade 9 protruding at the same time as the disk 8 with blade is driven to rotate by the frictional resistance of the anti-slip surface 11 is formed on the sheet. Cut holes 12 at regular intervals are made by piercing the S surface.
[0018]
Further, as shown in FIG. 1, if the cutter blade 9 can be adjusted in and out and / or detachable by the blade adjusting means 14 with the blade adjusting means 14, the cutter blade 9 can be immersed or detached. It is possible to prevent a hole from being opened in the sheet S at the attachment position of the cutter blade 9 in that portion, and in this way, the series interval of the cut holes 12 that can be easily opened in the sheet S can be adjusted. .
[0019]
Furthermore, the position of the rotary shaft 10 can be adjusted by sliding on the disk support shaft 6, and the upright support shaft 18 is slidably adjusted upright on a slide support shaft 16 provided at the front lower portion of the support base 1. In the form in which the disk moving means 15 having the disk support shaft 6 fixed to the upper end is provided, as shown in FIGS. 1, 2 and 3, the disk moving means 15 is used to rotate the rotating shaft 10 of the disk 8 with blades. The position is adjusted by sliding movement, and the position of the cut hole 12 of the sheet S can be adjusted.
Further, in the embodiment provided with the disk moving means 15 that allows the position of the rotary shaft 10 to be slidably adjusted on the disk support shaft 6, as shown in FIGS. 1, 2, and 3, as shown in FIGS. The position of the cut holes 12 of the sheet S and the mutual distance can be adjusted by changing the distance.
[0020]
In FIG. 1, the distance b is adjusted in the same way as the distance a and the distance c on both sides, and in FIG. 2, the distance d between the ends is narrow, and the distance e and the distance f between the center and another edge are the same. In FIG. 3, the cut holes 12 are arranged in three rows, and intervals g, h, i, j between them are different from each other.
As described above, the adjustment of the position and interval of the cut hole 12 can be achieved by simply sliding the slide moving shaft 17 of the bladed disk on the slide support shaft 16, and the adjustment operation is very simple.
[0021]
Then, a tension bar 13 for pulling the sheet S downward is installed between the roll support shaft 3 and the rotating shaft 10 of the bladed disk 8 on the support base 1 to remove the sheet looseness, Feeding and reliable cutting of the cut hole 12 can be performed.
In addition, it is preferable that the cut hole 12 is not cut and opened, but it is preferable for keeping heat and moisture, and weeds can be prevented from growing at the base of the crop.
[0022]
Then, when the sheet S is pulled out from the sheet roll 4 to cover the ridge, smooth sheet feeding is performed by the frictional resistance of the anti-slip surface 11, and the cutter blade protruding at the same time as the bladed disk 8 is automatically rotated. 9 punctures the sheet S surface with an accurate spacing and opens the cut holes 12 at regular intervals.
[0023]
【The invention's effect】
The present invention is as described above, and the present invention may be left with the sheet roll 4 attached, but if it is separated, it can be easily carried into the farmland.
Since the hole is automatically punched at the same time as the sheet is pulled out from the sheet roll 4, it is not necessary to perform another hole punching operation, and the work is reduced accordingly.
[0024]
Further, the interval and position of the cut holes 12 opened in the sheet can be easily performed on the farm ground by the blade adjusting means 14 and the disk moving means 15, and for example, the adjustment work of the series interval and the parallel interval becomes very easy.
Furthermore, if the cutter blade 9 that has become unbreakable due to blade spillage or the like is replaced with a new blade by the blade adjusting means 14, it becomes easy to maintain the sharpness.
Furthermore, since the whole structure is simple, the weight can be reduced and disassembly and assembly are easy, and there is an advantage that a product can be manufactured at an economical cost.
