Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a perforator for a plowing multi-sheet film.

<Conventional technology> Agricultural production technology has been constantly researched and developed in each field to improve marketability and profitability or its safety. Among them, as one of the effective cultivation technology, The effective use of the multi-sheet film for coating the film has been put to practical use and is already generally used for fixing.

However, because of its frequency of use, there is no dedicated tool for this work, and even if there is a multi-sheet film coating work machine from the scale of the cultivated land, there is no perforation tool for transplantation, so it covers multi-sheet film. Regarding the method of piercing the transplant hole later, it is done by each worker. For example, cutting a can of empty cans in a circle and performing the die cutting of the multi-sheet film surface covering the cultivated ground, or burning a burner flame directly on the multi-sheet film surface at a predetermined position to locally melt it. A method such as forming a lost portion is used.

Regarding the use of empty cans, etc., when pressing, it is intended to cut out the multi-sheet film by pushing a part of its tip into the ground.
In order to improve the cutting performance, it is necessary to push the empty can or the like while slightly swirling it, and to pull out the empty can. Also, it is bothersome and troublesome to collect and dispose of the cut pieces. Furthermore, since this is of course an application and utilization, the cutting edge of the sliced part becomes blunt immediately and cannot be cut, and as a result, the result of perforation is deteriorated and the state of multi-sheet film coating with good bending angle is messed up and ruined. I will do it.

Even those using burner flames require skill to use the equipment, and for example, various deformations and irregularities occur in the implantation holes during the process of operating the burner flames, which results in additional labor and gas cylinders. Necessary equipment, etc. Since it requires additional labor such as carrying and transporting equipment, etc., work efficiency is poor, which causes a high cost.

Plan in advance on a scale and perform the required perforation processing at a predetermined position of the multi-sheet film.
Ordering from a manufacturer is also one method, but it is not general, and of course it is costly, and due to the nature and form of the multi-sheet film itself, it also requires manual work during the coating operation of the multi-sheet film coating machine. Even at times, unreasonable force is sometimes applied to the peripheral portion of the machined hole, and there are many problems such as breakage and deformation of the hole arrangement, which is rather inefficient.

<Problems to be solved by the invention> The problem to be solved is that the use of empty cans and the like is for temporary application in the perforation work of multi-sheet film, and it requires more labor than necessary. The posture is also bad and it is troublesome to dispose of the excised pieces after collection.
Further, those using burner flames require skill to operate and handle them, and require additional labor for carrying equipment such as gas cylinders, which results in poor work efficiency and many troubles.

<Means for Solving the Problems> The present invention provides a means for facilitating the perforating work of a multi-sheet film, further comprising a multi-sheet film surface which can be vertically pressed by an outer cylinder portion provided with a pressing rod, A wave-shaped sharp blade at the lower end of the inner cylinder of the structure that can slide up and down with a slight swivel inside the outer cylinder cuts off with a slight protrusion during the descending stroke, and the cut piece is sharpened inside the inner cylinder. The most important feature is to pierce with a rod and collect it at the time of restoration. This has achieved the purpose of facilitating the required perforation work in a multi-sheet film covering the cultivated ground.

In other words, a plurality of supporting portions 17 that support the reciprocating movements of the plurality of rods 8 by vertically moving up and down,
The component device is mounted at a predetermined position on the rear part of the agricultural tractor 21. This allows flexible coupling 2 from the PTO shaft.
Crankshaft 13 with pulley 14 driven through 0
With the rotation operation of, the connecting rod 8 can be continuously moved for a required stroke of vertical descending and ascending via the crank pin portion 13 'and the connecting rod 15. At that time, the number of rods 8 to be used, the stroke size of the rods 8 and their intervals can be set according to the required perforation condition of the multi-sheet film 11. In addition, in order to correspond to the various conditions of the cultivated ground where the agricultural tractor is operated and to effectively perform the multi-sheet film perforation work, the lower end of the outer cylinder 1 with the rod 8 and the multi-sheet film 11 surface are The required height can be set and maintained by a predetermined device provided in the agricultural tractor, similarly to other work machines.

With the above arrangement, in the outer cylinder 1 with the rod 8 placed on the surface of the multi-sheet film 11 covering the cultivated ground, the downward pressing force in the vertical direction applied to the rod 8 is first the disk 7 and the return spring. The predetermined pressure is applied to the outer cylinder 1 via 6 to produce the multi-sheet film.
When the outer cylinder 1 presses the 11th surface and the pressing force further increases, the return spring 6 is compressed, and the descending rod 7 with the disk 7 presses the inner cylinder 2 inside the outer cylinder 1. Tube 2
The ridge 3 of the outer cylinder 1 on the surface of the multi-sheet film 11 is combined with the slanted groove 1'of the outer cylinder 1 so that a sharp wave-shaped blade 2'projecting in a downward stroke accompanied by a slight swivel is formed on the outer cylinder 1
The multi-sheet film 11 inside is cut off and rushed into the ground at a slight depth, at which time the sharp rod 9 in the center is pierced by the cut piece of the multi-sheet film 11, and the pressing of the rod 8 is released to return. It can be recovered by the restoring operation by the spring 6.

In the use of the present invention, first, the rod 8 applied to the required hole diameter in the multi-sheet film 11 to be used.
Select the set spare of the outer cylinder 1 with the bar handle 10
It is fastened and fixed to the rod 8 provided with the screw portion 8 '. At that time, oil is supplied to the sliding portion of the protrusion 3 which is engaged with the oblique groove 1 ′ of the outer cylinder 1, the operating state of the inner cylinder 2 in the outer cylinder 1 and the wave-shaped blade 2 ′ of the inner cylinder 2 and the center. Also inspect the sharpened rod 9 for abnormalities.

In the manual operation of FIG. 1 in the work, first, the outer cylinder 1 at the tip of the rod 8 is placed vertically at a predetermined position on the surface of the coated multi-sheet film 11, and then the bar handle 10
It is sufficient to press the outer cylinder 1 with a slight force. At this time, the return spring 6 is further compressed while pressing the outer cylinder 1, and the rod 8 is moved downward, and the sharp blade 2'of the inner cylinder 2 is moved downward in the outer cylinder 1 with a slight turning. The multi-sheet film 11 in 1 can be cut off. It should be noted that the excavation into the ground 12 at the time of excision feels a slight response. When the pressing is stopped, the return spring 6 immediately returns to the original state. In this way, the required boring work may be continued. Since the cut pieces of the multi-sheet film 11 are pierced by the sharpened rod 9 each time and collected in the inner cylinder 2, they may be taken out after the operation or appropriately taken out and processed.

When carrying out the automatic perforation work shown in Fig. 5, the required perforation work for the multi-sheet film 11 is performed in the same manner as other tillage work machines, except for the fixing device related to the PTO device and hydraulic device. , Rod 8 set / spare selection and some replacement / removal required for setting the number and intervals and necessary adjustment are required, but after the required setting of the push-down stroke size, it is automatically performed by the operation of the agricultural tractor 21.
