Further, during the silage preparation work, as shown in FIGS. 4 and 5, the material is loaded from the front end of the bunker silo 1 into the bucket 21a, and the leveling machine 19 is rotated in the opposite direction to that during the leveling work to rotate the bucket 21a. Run behind the bunker silo 1 while uniformly scraping the material from the. At this time bucket 21a
Performs a rotary movement to feed the material to the leveler 19. Next, the working machine frame 20 is lowered to a height at which sufficient front and rear stepping pressure rollers 17 and 18 are obtained, and the leveling machine 19 is normally rotated to correct the dispersion unevenness. , 18 and the wall surface tread roller 22 are pressed to perform leveling and treading work from the rear end of the bunker silo 1 toward the front. At this time, the wall surface treading roller 23 is always in contact with the wall surface of the bunker silo 1 by the horizontal link mechanism,
The rear treading rollers 17 and 18 tread near the silo sidewalls 4a and 4b, which are difficult to tread.

Here, in the case of a material that has a long cutting length and a low material moisture and is difficult to tread, front and rear tread rollers 17 and 18 are used at the same time in order to improve the tread accuracy of the material. Perform treading twice each during treading work.

Further, in the case of a material having a short cutting length and a high water content, which is easy to tread, the required power can be reduced by using the rear tread roller 18 alone.

In this manner, the work described above is repeated while the work implement frame 20 is not lifted at a constant thickness until the material reaches the upper surface of the bunker silo 1.

At the front and rear material inlets 2 and silage outlets 3 of the bunker silo 1, a predetermined frame (not shown) is installed according to the thickness of the material to be treaded to form a vertical end surface. As a result, the volumetric efficiency of the bunker silo 1 is increased, sufficient treading is possible to both end surfaces, loss due to deterioration is also reduced, and highly accurate preparation work is achieved.

Next, as shown in Fig. 6, when taking out the silage,
The take-out machine 25 and the take-out bucket 21b in which the blade of the leveling machine 19 is changed to a scraping blade are mounted on the work machine frame 20, and the front and rear stepping pressure rollers 17, 18 are removed. Then, the working machine frame 20 is raised to the upper end of the silage by the pantograph mechanism 10 and moved forward by a distance according to the take-out amount of silage, and the rotation of the take-out machine 25 scrapes out the silage to obtain a bucket.
Load on 21b. The bucket 21b moves horizontally and vertically to the position where the scraped silage is surely loaded, and is rotated by an angle corresponding to the loading amount to receive it, so that there is no loss. When the bucket 21b is filled with silage, the work machine frame 20
Retreats and transports to feeding device. In this way, this operation is repeated until the required feeding amount is reached.
