Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silo used for increasing the nutritional value of green grass used as feed for cattle and the like.

(Prior art) Conventional silos have a removable lid on the top of the bulkhead tank, and when storing grass etc. in the silo, the lid is opened and the grass is stored inside the silo, and the work is completed. The rear lid is designed to close.

(Problems to be Solved by the Invention) However, in a silo with such a structure, when putting grass in, it is only possible to store grass up to the upper end (input port) of the silo, and after storing the grass, The problem is that the air mixed in during feeding gathers upwards due to the weight of the grass, causing the grass to sink by about 20%, and as a result, the grass can only be stored at about 80% of the silo's capacity. There is a point. Furthermore, if there is a large amount of residual air in the silo, there is a problem in that rot is accelerated at the contact surface between the grass and the residual air.

(Objective of the present invention) In view of the above-mentioned problems of the prior art, the present invention provides a method for stacking grass high on the top of a silo in advance in consideration of the reduction in volume of grass after being stored in the silo. It is an object of the present invention to provide a silo capable of discharging residual air inside the silo to the outside in order to prevent grass from rotting inside the silo.

(Structure of the Invention) Therefore, in the present invention, a silo is provided with a partition wall tank having an open upper end, an exhaust hole provided at a position lower than the center of the partition wall to suck the air in the partition wall, and the partition wall. an elastic ring protruding from the upper end of the tank; an elastic engaging body having a groove and capable of engaging with the elastic ring; a first sheet that is inserted into the upper inner wall; a second sheet that is placed over the first sheet and whose ends are held between the elastic ring and the elastic engagement body; A third sheet is placed over the sheet, and the end portion of the third sheet is fixed to the partition wall by a tube.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of a silo according to the present invention, FIG. 2 is a cross-sectional view taken from FIG. 1, and FIG. 3 is a cross-sectional view taken from FIG. 1 with grass stored in the silo.
Figure 4 is a cross-sectional view of Figure 1 after the residual air has been discharged from the silo in the state shown in Figure 3, Figure 5 is a cross-sectional view of Figure 1, and Figure 6 is a view from the silo's inlet. It is a front sectional view of a state in which grass is piled up high.

In the figure, A is the silo, 1 is the bulkhead tank of silo A, 1
a indicates a partition wall. The partition wall tank A is provided with an exhaust hole 1b located lower than the center of the partition wall 1a, and a pipe 1d having a valve 1c is inserted into the exhaust hole 1b. This makes it possible to exhaust the air remaining in the silo A after storing the grass to the outside. An elastic ring 2 is fixed to the upper end of the partition tank 1 in a protruding state, and when storing grass in the silo A and covering the grass with a sheet 8, the peripheral edge of the sheet 8 is The sheet 8 is sandwiched between an elastic ring 2 and an elastic engaging body 3 having a groove, and the sheet 8 is attached to the silo A in an airtight manner.

In FIG. 1, reference numeral 4 denotes a take-out hole for taking out grass, 5 a lid for the take-out hole 4, and 6 a discharge hole for draining water accumulated in the silo A.

Next, the operation of this embodiment will be explained.

As shown in FIG. 5, a vinyl sheet 12 is pasted on the extraction hole 4 from inside the silo
After attaching the lid 5 from the outside of the silo via a gasket, grass is introduced from above the silo A shown in FIG. 1, and the grass 10 is piled up to the input opening. After that, in order to pile up grass beyond the height of the input port, several bamboos 14 are set up inside the silo A, a plywood board 15 is placed inside the bamboos 14, and a rope 16 is tightened around the bamboos 14.

In this way, build a wall above silo A,
With the sheet 7 hanging inside the wall, grass 10 is further thrown in, and the grass 10 is piled up higher than the silo A (see FIG. 6). Next, the bamboo 14 and the plywood board 1
5 is removed and the grass 10 is wrapped in the sheet 7. Then, the sheet 8 is placed over the sheet 7, and the lower edge 8a of the sheet 8 is sandwiched between the elastic ring 2 and the elastic engagement body 3 as described above, thereby fixing the sheet 8 to the silo A in an airtight state. (See Figure 3). Next, as shown in FIG. 3, the exhaust hole 1b
A household vacuum cleaner 10 is connected to the pipe 9 via a pipe 9,
The vacuum cleaner 10 sucks the residual air inside the silo A and discharges it to the outside. As a result, the volume of the grass 10 in the silo A is reduced by about 20%, so the grass 10 is forcibly compressed, and the same effect as the pressing operation of the grass 10 is automatically performed. As described above, due to the forced discharge of residual air, the volume of grass 10 in silo A is reduced by about 20%, but as mentioned above, grass 10 is placed in the upper part of silo A to take this reduction into account. Since the grass is piled up high, grass 10 can be stored in an amount greater than the capacity of silo A.

By the way, if the state shown in Fig. 3 remains, a depression will be formed inside the elastic ring 2 into which the elastic engagement body 3 is fitted, so rainwater will accumulate in this depression, and this accumulated rainwater will generate heat. and grass 10 in silo A
There is a risk of burning. Therefore, in the present invention, as shown in FIG. 4, a sheet 9 is further placed over the sheet 8, and the end portion of the sheet 9 is fixed to the partition wall 1a by a tube 11. By configuring like this, grass 1
Since rainwater does not accumulate in the upper part of silo A after silo A is stored, grass 10 in silo A will not be burnt. In addition, since the upper part of silo A is covered with three sheets 7, 8, and 9, the sheets will not be torn by the grass 10 inside silo A, and as a result, air and water will not leak into silo A. Grass 10 in Silo A will not rot after entering. After storing grass 10 in silo A as described above, leave it as it is for about one month, and then store grass 10 in silo A.
After fermentation, it is used as feed for cattle.

(Effects of the Invention) Since the present invention is configured as described above, it has an excellent effect of forcibly discharging the residual air in the silo and preventing the stored grass from rotting. In addition, by forcibly discharging residual air, the volume of the grass stored in the silo can be reduced and the grass can be forcibly compressed, so the same effect as the grass trampling operation can be achieved automatically. It has the excellent effect of being able to. Furthermore, since the grass can be piled up high on the top of the silo in advance in consideration of the reduction in the volume of grass in the silo, it has the excellent effect of being able to store more grass than the volume of the silo. In addition, since the top of the silo is covered with three sheets, the sheets will not be torn by the grass inside the silo, and as a result, air and water will enter the silo and the grass inside the silo will rot. It has an excellent effect that it never happens. Furthermore, by fixing the edge of the top sheet of the three sheets to the bulkhead, no dents will be formed on the sheet, and as a result, rainwater collected at the top of the silo will heat up. There is no risk that the grass in the silo will be burnt.
