Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for lifting up a net hung over rush grass in order to prevent the rush from lodging and being damaged.

[Conventional technology]

When cultivating rush grass, a net is hung to prevent the produced rush from falling over in any direction, damaging it, and preventing it from getting tangled.When harvesting, this net is manually cut in rows or several rows at a time. It was being turned over one after another toward the uncut land side.

[Problem to be solved by the invention]

However, this net is large and quite heavy, and it takes a lot of effort to remove the net from the rush and lift it over the uncut grass, resulting in extremely inefficient work.

The present invention has been made in view of these circumstances, and an object of the present invention is to provide a device that can automatically turn up and collect nets as harvesting progresses.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a plurality of winding ropes each connected to a plurality of locations in the direction of the plant rows at the side ends of a lodging prevention net hung over the planted straw grass. a winding drum, a motor for independently driving each winding drum, a means for detecting rope tension for each winding drum, and means for operating the motor to wind when the rope tension decreases, so that the rope tension becomes larger than a set value. We have developed a rope lifting device for a strawberry harvesting boat, which is equipped with a motor control means that stops the motor when the problem occurs.

[Function] According to the configuration of the present invention, when the rice grass harvester moves forward along the row of plants, the rice grass in the cutting row is cut and harvested while passing through the net downwardly, and the part of the net from which the straw grass has fallen is used as planted uncut rice grass. It hangs down on the mowed field side.

The tension of the hoisting rope connected to the hanging net portion is small, and the motor of the winding drum closest to the net portion is driven to perform lobe winding. As a result, the hanging part of the net is lifted up onto the planted uncut grass, and when it is lifted up to a certain extent, the rope tension increases beyond the setting due to the net's catching resistance on the uncut grass, and based on this, the motor is activated. It is stopped and winding is no longer performed.

These operations are carried out sequentially as the aircraft advances, and each winding drum sequentially turns over the portions of the net that have fallen down due to the rushes passing through.

〔Effect of the invention〕

As described above, according to the present invention, the net removed from the rush can be automatically turned over onto the uncut grass as the mowing progresses, and labor can be significantly reduced.

Next, the operation of the net winding device (B) constructed as described above will be explained.

As shown in Figure 1, the rope (23) where the net (N) is rolled up over the planted and uncut grass has a tension higher than the set value, and as shown in Figure 2, the tension The detection roller (27) is largely lifted by the rope tension, the switch (30) is no longer pressed by the cam (29), and the motor (22) is in a stopped state.

As the rice grass harvester (A) moves forward as shown in Figure 9, the rice grass in the cutting row passes through y4 (N) and is harvested as described above, and the part of the net through which the rice grass has passed is planted and uncut. It hangs down on the side of the grass mowed area, that is, on the left side of the aircraft in the 9th round.

Like this 'f! 4 (N) hangs down, the rope (23) near it becomes slack and the tension decreases, and as a result, as shown in Figure 3, the tension detection roller (27) is activated by the spring (26). pulled down, cam (29)
presses the switch (30). As a result, the motor (22) is energized and the rope is wound by the winding tram (20). At this time, due to the rope winding tension, the tension detection roller (27)
can be lifted up a little, but even in this state the switch (30)
