Reference numeral 29 indicates a hollow base (see Figure 1). On the top surface of this base 29, large and small screens 30, 31, and 32 are arranged. Figure 6 shows the arrangement of these screens. Shown in plan view.

An opening 33 is provided in the center of the screen 30, and this central opening 33 is located directly below the plug 12 supported at the center of the roof body 1 and has approximately the same diameter as the plug. ing.

34 is a dryer, and 35 is a fan, which are installed in a casing 36 that communicates with the inside of the base 29 to supply dry hot air at an appropriate temperature into the base 29.

37 is a conveyor that loads the grass scraped off by the unloading rake 11 and transports it from inside the base 29 to the outside cow shed 38; This shows a blower for feeding to the IJ viewer 2.

FIG. 7 shows in detail the arrangement and mounting state of the unloading rake 11, in which each gang 11 has a plurality (for example, six) of unloading pawl wheels 1lb... attached thereto.

The 18 pawl wheels 1lb... attached to the three gangs 11c are arranged so as to be slightly shifted from each other so that the orbits of the respective pawl wheels do not overlap each other when the gang 11c rotates. has been done.

(See Fig. 7) Reference numeral 51 is a stopper projecting from the roof body 1 and is designed to be engaged with three pillars made of H-shaped steel, so that even if the threaded rod 43 rotates, the roof body 1 prevent it from rotating.

Next, the operation of the Haytower constructed as described above will be explained.

The motor 44 is operated to rotate the screw rod 43, the roof body 1 is lowered, and the skirt portion 18 is attached to the screens 30 to 3 of the base 29.
2, the skirt portions 18A constituting the skirt portion 18 are connected to each other with bolts and nuts as shown in FIG. 43 and attached to the traction rod 6, and the traction rod 6
A leveling rake (not shown) for leveling the grass uniformly is attached to a support ring 9 suspended by a wire 8.

Then, the grass, which has been dried in advance and cut into appropriate lengths, is passed through the chute 3 by the blower 39 and delivered to the roof body 1.
While feeding the disk to the IJ viewer 2, the threaded rod 43 is rotated in the opposite direction to that described above.

Then, since the roof body 1 is supported by the screw rod 43 via the screw seat 48, it is raised by the rotation of the screw rod 43.

The struts 24 prevent the roof body 1 from rotating due to the frictional resistance between the screw rods 43 and the screw seats 48, and the roof body 1 and each member supported by the roof body 1 rise smoothly.

Further, a catch seat 49 is spline-fitted to the screw rod 43.
will rotate with the rotation of the threaded rod 43 (9th
(see figure), disk} The rotating part 2B of the IJ viewer 2 and the traction rod 6 also rotate around the threaded rod 43.

In this way, the rotating part 2B and the traction rod 6 of the distributor 2 rotate, but the rotating part 2B is supported by the roof body 1 via the fixed part 2A of the distributor 2, and rotates as the roof body 1 rises. while rising.

In this way, the rotary part 2B of the distributor 2 rotates while the roof body 1 etc. rises, and the grass is dropped onto the base 29 surrounded by the skirt part 18, and the grass is shaped like a donut around the plug 12. The deposited layers 40 are sequentially formed.

When the deposited layer 40 has been formed to a certain extent, the dryer 34 and fan 35 are started to supply dry hot air into the base 29.

The supplied dry hot air flows through the screen 30 as shown by the arrow in Figure 1.
32 and rises through the central opening 33 to forcefully dry the deposited layer 40.

Further, as described above, the traction rod 6 also rotates, whereby the leveling rake (not shown) rotates and the grass is deposited uniformly.

As described above, the grass pile layer 40 is continuously formed, and the plug 12 is also gradually raised by a drive motor (not shown) and an appropriate transmission mechanism, so that the doughnut-shaped pile layer 40 is formed.

When taking out grass from the tonohei tower, as shown in FIG. Nasu.

The motor 44 is then actuated to rotate the threaded rod 43 in the opposite direction to that used in the deposition operation.

Then, the unloading rake 11 rotates around the threaded rod 43 and gradually scrapes the grass from the upper layer to the central drop opening 41.
The grass is dropped from the grass through the opening 33 and the hopper 42 onto a conveyor 37, and the conveyor 37 transports the grass to a cow shed 38.

When the unloading rake 11 performs the scraping work, the roof body 1 also gradually descends, so the unloading rake 11 also gradually descends, and the scraping work of the unloading rake 11 is performed continuously.

Note that when taking out grass, the skirt portion 18
This is done after uncoupling the skirt plates 18A that make up the structure so that they can open outward.

The present invention has the above-described structure, and the roof body and each member attached to the roof body are automatically raised and lowered when the unloading rake or the leveling rake is operated, so that the grass accumulation work is carried out. The scraping operation can be carried out continuously, which has a great practical effect.
