Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wave extinguishing device in a paddy field work machine, and in particular, it is possible to propagate a wave of a farm scene generated by a traveling wheel to a side of a previously planted side even when planting is performed at high speed. The present invention relates to a wave extinguishing device in a paddy field work machine that can be suppressed. Here, the wave-dissipating body is to loosen the waves or to reduce the momentum of the waves.
[0002]
[Prior art]
Generally, a paddy field work machine such as a riding rice transplanter in which a work machine is connected to the rear of the traveling machine body is known, but such a conventional paddy field work machine has a front wheel a as shown in FIG. Since there is no shield to block the front, when planting work, the farm scene is rippled by the flow c of muddy water pushed by the front of the traveling wheel a rolling on the cultivator b .
[0003]
In particular, when the speed of the aircraft is increased to improve work efficiency, a large wave is generated on the front of the traveling wheel, and such waves spread to the sides of the aircraft and push down existing planted seedlings or lift them up. As a result, there was a problem of hindering the planting work.
[0004]
[Problems to be solved by the invention]
The present invention was created to solve the above-described conventional problems, and even when a large wave is generated on the front surface of the traveling wheel as the aircraft travels, such a wave is automatically generated. It is intended to provide a wave extinguishing device in a paddy field machine that can be gently attenuated to prevent the existing seedlings on the side of the machine body from being pushed down.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the technical means taken by the present invention is to form a bulging portion on the wave-dissipating body, and place the upper surface of the bulging portion on the muddy water surface of the farm field in front of the traveling wheel. The rearward waves generated at the bulging part as the aircraft travels interferes with the waves generated at the front of the wheel to suppress the spread to the side of the existing seedlings. It is.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings of an example. First, in FIG. 1, 1 is a traveling machine body of a riding rice transplanter exemplified as a paddy field work machine, and an engine unit 5 is mounted on a front part of a machine body frame 4 having front wheels 2 and rear wheels 3 as traveling wheels. A driver's seat 6 is disposed behind the driver's seat 6. Reference numeral 7 denotes a steering handle. A planting work machine 8 is connected to the rear part of the machine body frame 4 through a link mechanism 9 so as to be controlled up and down.
[0007]
Reference numeral 10 denotes a planting part frame of the planting work machine 8. The planting part frame 10 is formed of a square pipe in the left-right direction, and extends rearward on the lower surface side of the planting part frame 10. A plurality of planter cases 11 are fixed in parallel. A planter 13 for planting operation is attached to a rotating shaft 12 provided at the rear end of the planter case 11.
[0008]
In addition, a planter drive shaft 14 is disposed at the front portion of the planter case 11, and the power from the planter drive shaft 14 is transmitted to the rotary shaft 12 via a transmission mechanism built in the planter case 11, and rotates. A planter 13 is planted by the shaft 12. Power from the engine unit 5 is transmitted to the planter drive shaft 14 through an intermediate shaft, a transmission case, and the like.
[0009]
Above the planter case 11, a seedling platform 15 that is reciprocally laterally fed is arranged in a low shape before and after the planter. Below the planter case 11, a float unit 16 that slides on the rice field can move up and down. It is attached to. Reference numeral 17 denotes a seedling vertical feed device provided on the back side of the seedling mounting table 15, and 18 denotes an apron for receiving the seedlings arranged facing the lower end of the seedling mounting table 15.
[0010]
As shown in FIG. 2, the float section 16 is a three float type in which a center float 16a and side floats 16b and 16b are arranged side by side at a predetermined interval. Each of the center float 16a and the side float 16b is formed in a T shape in a plan view in which the tip is a wide flat surface and the rear side is a narrow sliding surface. From the front to the rear end of the planter case 11. The planter 13 serves as a six-row planting transplanter for planting the seedlings P on both sides of the rear part of each float.
[0011]
The front wheels 2 and the rear wheels 3 are arranged in series in front of the side floats 16b and 16b, but by attaching wave-dissipating bodies 19 and 19 in front of the front wheels 2 and 2, the aircraft body The backward waves generated by the wave-dissipating body 19 as the vehicle travels are made to interfere with the waves generated on the front surface of the front wheel 2 to suppress the waves spreading to the side of the aircraft.
[0012]
That is, the wave-dissipating body 19 includes a mounting portion 21 supported by a support frame 20 that can be turned up and down provided at the front end of the body frame 4 as shown in FIG. And are integrally formed.
[0013]
The bulging portion 22 is formed in a sharp shape that shrinks toward the front. During planting work, the bulging portion 22 is positioned in the muddy water of the farm field so that the bulging portion 22 is submerged in an arc shape. The formed upper surface is slightly exposed on the water surface.
[0014]
Moreover, the attachment part 21 is formed in the boat shape which the front-end | tip part became the circular-arc-shaped waved surface, and the support rod 23 is standingly arranged by the upper surface. The mounting position of the wave-dissipating body 19 can be adjusted up and down by inserting a support rod 23 slidably into an insertion portion 24 provided at the tip of the support frame 20 and fixing it with a stop bolt 25. .
[0015]
Since it comprised as mentioned above, when planting work, if the wave-dissipating body 19 is attached to the front of the front wheel 2 as shown in FIG. 3, the wave-dissipating body 19 bulges as the aircraft progresses. When the part 22 moves in the muddy water of the field, as shown in FIG. 4, the bulging part 22 gently pushes the muddy water, reduces the muddy water in front of the wheels, and suppresses the ripples caused by the wheels. At the same time, a gradual muddy water flow a toward the rear along the side surface of the bulging portion 22 is generated by the bulging portion 22 located in the muddy water. And among this muddy water flow a, the muddy water flow near the water surface rises on the water surface and a wave is generated.
[0016]
Further, since the front wheel 2 has a shape in which the front surface in the traveling direction is close to a flat surface, the muddy water flow generated on the front surface of the wheel is difficult to flow rearward, and thus a large wave is generated in front of the wheel.
[0017]
Therefore, by providing the wave-dissipating body 19 and reducing muddy water in front of the wheels, the waves generated by the front wheel 2 are reduced, and a backward wave generated by the wave-dissipating body 19 is generated in front of the front wheel 2. Since the wave momentum is attenuated by interfering with the waves, the waves generated by the wheels do not spread to the side of the aircraft and push down the existing seedlings P.
[0018]
Moreover, since the wave-dissipating body 19 can be accommodated upward by rotating the support frame 20, the wave-dissipating body 19 is not damaged by colliding with the corrugated body 19 at the edge, and can be operated safely. .
[0019]
【The invention's effect】
In short, the present invention forms a bulging part in the wave-dissipating body, positions the bulging part in the muddy water of the agricultural field and provides it in front of the traveling wheel, and causes the rear part generated in the bulging part as the machine body travels. Is configured to interfere with the waves generated on the front surface of the wheel to suppress the spread to the side of the existing seedlings. The bulging part of the wave-dissipating body provided in front of the wheel gently pushes off the muddy water in the field and reduces the muddy water in front of the wheels, thereby suppressing the undulations caused by the wheels and at the same time, The backward wave generated by the upper surface of the wheel interferes with the wave generated by the front surface of the traveling wheel, thereby reducing the wave momentum.
[0020]
For this reason, even if planting work is performed at a high speed in order to improve the work efficiency, it is possible to suppress the ripples spreading to the side generated by the traveling wheels, and orderly without defeating the existing seedlings Planting work can be done.
