Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rush seedling digging device used for digging rush seedlings for transplantation to other fields.

[Conventional technology]

Conventionally, a single stake with a pulley attached to it is erected on one side of the field where rush seedlings were cultivated, and the rush seedlings in rows on both sides of the post are placed on a seedling excavator like the one shown in Figure 4, with a wire attached to the pulley. The seedling excavator was pulled from inside the field by a tow vehicle such as a tractor or transport vehicle connected via a turret, and the seedling excavator was moved between adjacent rows of rush seedlings to dig them out.
In this case, for example, if the tow vehicle was on the road outside the field, the tow vehicle pulling the wire would obstruct traffic, and the excavation work would often have to be stopped. In addition, when pulling a seedling excavator by using a single pulley to bring the tractor into the field, if the bending angle of the wire around the wire exceeds 90°, the force that resists the bending of the wire near the pulley will increase. This is thought to be due to the action of the seedling excavator, but it was difficult to excavate grass seedlings because the seedling excavator moved in an arc shape instead of going straight between the rows of rush seedlings.

[Problem that the invention attempts to solve]

An object of the present invention is to provide a rush seedling digging device that allows a tractor to be placed in a field to dig up grass seedlings.

[Means for solving problems]

The rush seedling digging device of the present invention includes a pulley holding device that can be installed on one side of a field, two pulleys attached to it, a known seedling digging machine, a tractor, and a pulley. It consists of a wire that connects the seedling excavator and the tow vehicle via the wire.

Next, the present invention will be described in detail with reference to embodiments and drawings.

〔Example〕

Figure 1 shows the rush seedling digging device of the present invention.
This is a conceptual diagram showing a state in which it is installed in a field 10 where . FIG. 2 shows a plan view of the pulley holding device 1 according to the present invention together with a pulley 6 attached thereto, indicated by dotted lines. FIG. 3 is also shown in a front view. FIG. 4 shows the seedling excavator 7 together with rush seedlings 11 being dug.

As shown in FIGS. 2 and 3, the pulley holding device 1 is composed of a tubular body 2 and a stake 5. As shown in FIGS. In this example, the tube body 2 has a plurality of pile attachment tube sections 3 erected on both sides and in the center. The side wall of the pile attachment pipe section 3 is provided with a set screw 12 for fixing the inserted pile 5. Two pulley mounting pipe parts 4 having setscrews 13 on the side walls are loosely fitted between the pile mounting pipe parts 3, 3 of the pipe body 2, and slide along the pipe body, as well as attaching to the pile mounting pipe parts 3 of the pipe body 2. It can be fixed at any position with a set screw 13. In the figure, reference numeral 14 denotes a bridge-shaped protrusion provided for removably attaching the pulley 6 by means of screwing, locking, clamping, or the like. Since the pulley holding device 1 according to the present invention has the above-described structure, it can be installed between rows of rush seedlings 11 in a field 10 in an assembled state as shown in the figure.

In FIG. 1, a pulley holding device 1 is set up on one side of a field 10, a pulley 6 is attached to each of the two pulley attachment tube sections 4 mentioned above, and the tube sections are fixed to the tube body 2 with setscrews 13. A rush seedling digging device according to the present invention is installed in a field 10 by connecting a seedling digging machine 7 with a pulley 6 and a tractor 8 placed in the field 10 with a wire 9. At this time, as shown in the figure, the seedling excavator 7
is located between the rows of adjacent rush seedlings 11, and the wire 9 leading to the pulley 6 near the seedling excavator 7 extends parallel to the rows of rush seedlings 11 between the rows.
, and fix the tube portion to the tube body 2 with a set screw 13. The pulley attachment pipe portion 4 to which the other pulley 6, which is closer to the traction vehicle 8, is attached is also fixed in the same manner. As shown by the solid line, when the tractor 8 is placed inside the field 10 and pulled using the two pulleys 6, the seedling excavator 7 rush seedlings 1
Satisfactory excavation work can be performed by going straight between the rows of 1. Further, as shown by the dotted line, when the tractor 8 is used outside the field 10, if one pulley 6 is used, the seedling excavator 7 can similarly move straight and perform satisfactory digging work.

[Effect of idea]

According to the present invention, there is an effect that the towing vehicle can be used not only outside the field but also inside the field to perform excavation work.
