Attach the position regulating plate 25 to the front plate 11, and
7. Attach the second part of the adjustment lever 23 to the convex portion 26 of the temporary regulation 25,
J, the one-bar lever 23 is engaged by its own spring elastic action, and a U-shaped groove 27 is formed at the lower end of the adjustment lever 23.
is engaged with the engagement pin 22, and the adjustment lever 23 is engaged with the front plate 11.
Press it to the side and release the :JYJ joint lever 23 from the toothed part 26, continue to swing the adjustment lever 23 around the center bin 24, and slide the temporary slide 20 left and right to adjust the opening amount of the fertilizer spreading hole 18. It is designed to be adjustable.

Further, the vibrator groove 28 is formed in the vertical portion 4 of the mounting frame 4.
Attach the holding frame 29 to the 1tl using the port 30, and
A rotating shaft 31 is horizontally installed in a j-frame 29 so as to be freely rotatable with a bearing 32,
An eccentric member 33 is attached to this rotating shaft 31, and the rotating shaft 31 is connected to a power take-off shaft 34 of the traveling aircraft 1, an intermediate shaft 35, and a gear 36.
．． 37, the power is transmitted through the flexible hand 38, and the eccentricity of the eccentric member 33 acts to move the mounting frame 4 body onto the carrier 5.
It is designed to vibrate in the direction of travel.

Reference numeral 39 denotes a plow member, which is attached between the vertical portions 4b of the mounting frame 1 so as to be retractable and removable.

Further, a triangular blade portion 40 used for snow removal etc. is provided at the rear edge of the opening of the bottom plate 10.

Further, a top sand inlet 41 is formed in the front plate 13 of the transport platform 5, and the top sand inlet 41 can be closed by a lid member 42.

Since this embodiment has the above-mentioned configuration, the plowing member 39 is held in the upper retracted position or removed, and the earth and sand inlet 41
5 members 42 to close it, store powdered, granular, etc. fertilizer a in the transport platform 5, adjust the opening amount of the fertilizer spreading hole 18 with the adjustment lever 23, and rotate the power take-off shaft 34. When the machine (1) rotates the eccentric member 33 of 28, vibrates the mounting frame 1, and moves the traveling machine body 1 by itself, the fertilizer a falls from the fertilizer spreading hole 18, and the fertilizer a can be dispersed in the field. can.

At this time, the vibration mechanism 28 applies vibration to the transport platform 5 in the direction of movement of the transport platform 5, so that the vibration not only promotes the fall of the fertilizer a from the fertilizer spreading holes 18, but also the fertilizer a. Since the fertilizer is subjected to vibrations in the direction of movement of the transport platform 5, it is suppressed from moving in the direction perpendicular to the direction of movement of the transport platform 5, that is, in the left and right directions, and from accumulating unevenly in the left and right corners of the bottom of the transport platform 5. This allows the fertilizer a in the transport platform 5 to be spread evenly and more completely.

In addition, if the transport platform 5 is placed in an upwardly rearward oblique manner by the connecting mechanism 2, the fertilizer a can be smoothly transferred on the bottom plate 10 toward the fertilizer spreading hole 18.

Further, the remaining fertilizer in the carrier 5 can be discharged by releasing the holding mechanism 15 and tilting the carrier 5 backward.

In addition, if the plow member 39 is provided to protrude downward, the cover member 42 is removed to open the soil introduction port 42, and the traveling body 1 is moved forward, the field soil is removed by the plow member 39 and introduced into the transport platform 5. Then, the earth and sand at high places are introduced, the holding mechanism 15 is released at low places, and the earth and sand in the transport platform 5 is discharged, thereby making it possible to perform land leveling work to correct the height of the field.

In addition, by moving the traveling body 1 backward, the self-recording blade section 40 can
Can be used to level the earth and sand, and especially to remove snow.

Further, the position of the fertilizer spreading hole 18 may be at the lower part of the carrier 5, for example, at or near the boundary between the curved plate 11 and the bottom plate IO, or at or near the boundary between the rear plate 13 and the bottom plate IO. can also be applied.

In the above embodiment, the eccentric member 33 of the vibration mechanism 28 is configured to rotate vertically in the direction of movement of the transport platform 5, but it is arranged so that it rotates horizontally in the direction of movement of the transport platform 5, that is, the eccentric member 33 when viewed from the plane. Almost the same effect can be obtained even if the member 33 is made to look fan-shaped.

Furthermore, the vibration mechanism 28 is not limited to the one based on the eccentric member 33;
For example, a structure in which vibration is generated by a hydraulic mechanism or the like may be adopted.

〔Effect of the invention〕

As described above, the present invention allows powdered, granular, etc. fertilizers in the transport platform to fall through the fertilizer distribution holes and scatter the fertilizer onto the field, and at this time, the transport platform uses a vibration mechanism. Since the vibration is given in the direction of travel, it goes without saying that this vibration helps the fertilizer fall from the fertilizer spreading hole, and since the fertilizer is subjected to vibration in the direction of travel of the transport platform, it is perpendicular to the direction of travel of the transport platform. It is possible to prevent the fertilizer from moving in the shifting direction, that is, from side to side, and from accumulating unevenly in the left and right corners of the bottom of the carrier, which allows the fertilizer inside the carrier to be spread evenly, and more or less completely. Can be distributed.

As described above, the intended purpose can be fully achieved.
