These spring receivers 17 include a lower vertical portion 17a extending in the vertical direction Y, an intermediate inclined portion 17b that is continuous with the upper end of the lower vertical portion 17a and is inclined in a direction away from each other, and an intermediate inclined portion 17b It consists of an upper side vertical portion 17c that is continuous with the upper end and extends upward. The lower vertical portion 17a of the spring receiver 17 is screwed to both side surfaces of the support column 16, and an oval through hole 17d having a vertical direction Y as a major axis direction is provided in the upper vertical portion 17c, and the through hole 17d is provided in the through hole 17d. The hook 15 protruding from the power transmission member 12 is penetrated, and the power transmission member 12 is held so as to be able to reciprocate in the vertical direction Y.
On the other hand, hook rods 18 project in the left-right direction X on both outer surfaces on the lower side of the support column 16 with a gap from the pressing substrate 13.
A tension spring 19 that urges the upper and lower hooking rods 15, 18 in a direction approaching each other is stretched so that the lower end surface 12 a of the power transmission member 12 contacts the upper end surface 16 a of the column 16. Is energized.

The width in the left-right direction X of the pressing substrate 13 made of the rectangular flat plate is set to correspond to the width of the nursery bed. The pressing substrate 13 is provided with a frame portion 20 on the periphery of a flat plate, and an inverted U-shaped conveying frame 21 is provided on the frame portion 20a in the left-right direction X so as to protrude upward. A work handle 22 is provided on the advancing direction side 21a of the transport frame 21, and a switch 23 for operating the engine is provided on the other side 21b.
The work handle 22 includes a handle member 22a and a connecting member 22b connected to the tip of the handle member, and is a resin string made of polypropylene or the like that does not transmit vibration to the connecting member 22b.
Further, a temporary placing rod 29 is provided on the side portion 21a of the transport frame 21 so that the pulling handle 22 is hooked on the temporary placing rod 29 when the work pull 22 is not used.

Next, the operation of the seedbed leveling machine 10 will be described.
In a state where the engine 11 of the seedbed leveling machine 10 is stopped, as shown in FIG. 2, the power transmission member 12 is urged by the tension spring 19, and the power transmission member 12 is applied to the upper end surface 16 a of the column 16 on the pressing substrate 13 side. The lower end surface 12a of this is abuttingly disposed.

When the engine 23 is operated by operating the switch 23, the power transmission member 12 reciprocates in the vertical direction Y by the power generated by the engine 11.
As shown in FIG. 3, the power transmission means 12 positioned on the upper end surface 16 a of the support 16 on the tension spring 19 in the engine stop state causes the support 16 to move in conjunction with the downward movement of the power transmission member 12 by the engine 11. Acting downward, it generates a striking vibration that is applied to the surface of the nursery. In this way, by causing the power transmission member 12 to reciprocate up and down by the engine 11, it is possible to repeatedly apply impact vibration to the pressing substrate 13 at a high speed.

  In addition, since the power transmission member 12 is constantly urged by the tension spring 19 so as to be positioned on the column 16, the gravity of the power transmission member 12 and the engine 11 is loaded on the pressing substrate 13 via the column 16. Therefore, it is possible to generate a load capable of leveling the nursery bed simply by placing the pressing substrate 13 on the nursery bed.

When leveling a nursery bed (not shown) using the nursery leveling machine 10, the nursery leveling machine 10 is placed on the surface of the nursery bed.
In this state, the engine 11 is operated to vibrate the pressing substrate 13, and the impact vibration is applied to the nursery bed to pulverize the soil mass, and the gravity of the engine 11 and the power transmission member 12 is pressed via the support column 16. Is constantly loaded to press and level the nursery bed surface.
In this way, while leveling the seedbed of the portion on which the pressing substrate 13 is placed, the worker moves the seedbed leveling machine 10 with the handle 22 and sequentially performs leveling work. At this time, since the rubber plate 24 passes over the surface of the nursery bed leveled by the pressing substrate 13, the surface of the nursery bed is further leveled by the rubber plate 24.

According to the above-described configuration, the vibration generated by the engine 11 generates a striking vibration in the pressing substrate 13, and the striking vibration can pulverize the ground mass of the nursery bed, thereby softening the upper seedbed layer. In addition, since the pressing substrate 13 is always in pressure contact with the nursery bed surface, the nursery bed surface can be leveled.
As described above, it is possible to facilitate the work of leveling the seedbed to shorten the work time and save labor, and to level the seedling sufficiently to the extent that it can be in close contact with the seedling box, so that the emergence is aligned. be able to.

FIG. 4 shows a second embodiment of the present invention.
In the seedbed leveling machine 10 ′ of the present embodiment, the flat plate portion of the pressing substrate 13 ′ is formed of a mesh material made of a metal wire with a plurality of holes 13a.
Further, an annular belt 25 having elasticity is used instead of the tension spring of the first embodiment, and the annular belt 25 is hooked on the hooking rod 15 on the engine 11 side and the hooking rod 18 on the pressing substrate 13 side.
Further, a vertical frame portion 26 surrounding the engine 11 in the vertical direction is attached to the housing 14 of the power transmission member 12, and a horizontal frame portion 27 surrounding the engine 11 in the horizontal direction is fixedly attached to the vertical frame portion 26. The horizontal frame 27 is provided with a T-shaped handle 28 protruding in the left-right direction X.

According to the said structure, the leveling work of a nursery can be easily performed using the motive power of the engine 11, like 1st Embodiment.
Moreover, the clump of the nursery bed can be efficiently pulverized by the mesh of the press substrate 13 ′.
Furthermore, since the handle 28 held by the worker is attached to the engine 11 side instead of the press substrate side, it is possible to prevent the striking vibration of the press substrate 13 ′ from being directly transmitted to the worker. In addition, since another structure and an effect are the same as that of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
