Description

[Detailed Description of the Invention] The present invention relates to an airtight silo in which it is easy to cover the silo body with a canopy and to remove it from the silo body.

Conventionally, the following methods have been used to cover or remove canopies.

In other words, methods such as having multiple people climb onto a footstool and lifting the canopy by hand, or using a crane truck to lift the canopy, etc., were used.

However, the former method has the disadvantage that the canopy is heavy, so it cannot be done by one person and requires the hands of multiple people, and the work is also dangerous.

Furthermore, the latter method has drawbacks such as being expensive and requiring a lane vehicle, and the crane vehicle cannot be used unless it is in a location with convenient transportation.

The airtight silo based on the present invention solves all of the above-mentioned drawbacks and has the following configuration.

That is, a cylindrical silo main body A having a manhole C has a groove formed by molding a peripheral wall plate E along the outer peripheral edge thereof, and the end portion of the canopy B is inserted into the groove, and the canopy B is attached to the silo main body. In an airtight silo made of fiber-reinforced synthetic resin that covers A and injects liquid into the groove to isolate the silo body A from the outside, winch 3
At least two
A column 4-2 to which a pulley, a brim 5, and an arm 6 having a truss beam configuration are fixed is fitted, making the column 4-2 freely rotatable.One end of the rope 9 is tied to the winch 3, and the other end is attached to the column 4-2. A canopy lifting device is installed on the silo main body A side, and is made up of a rope 9 placed above the canopy B through a pulley fixed to a support post 4-2.

Hereinafter, the airtight silo of the present invention will be explained based on the drawings.

FIG. 1 shows a specific example of an airtight silo before the canopy lifting device is installed.

This airtight silo has a groove along the outer periphery of a cylindrical silo body A having a manhole C, and the end of the canopy B to which the handle F is fixed is inserted into the groove to open the canopy B. It is placed over main body A, and liquid is injected into the groove to isolate the inside and outside of the silo main body.

The groove is constructed by integrally molding a peripheral wall plate E on the outer peripheral edge of the silo body A.

This airtight silo is made of fiber-reinforced synthetic resin.

Glass fiber is suitable as the fiber, and unsaturated polyester resin is suitable as the synthetic resin.

Figure 2 shows a specific example of the canopy lifting device, which consists of a support 1 attached to the rib G of the manhole C, a support 2 attached to the surrounding wall plate E, and a hollow pipe-shaped metal support to which a winch 3 is fixed. A support 4-2 having a diameter smaller than the inner diameter of the support 4-1 is fitted into the support 4-1.
2 is configured to rotate freely.

Although the support plate is not shown, it may be attached directly to the silo body A rather than to the rib G.

A collar-shaped metal fitting 5 for adjusting the height is fixed to the column 4-2, and an arm 6 having a truss beam structure is attached to the upper part of the column 4-2.
is fixed horizontally to the support column 4-2.

Arm 6 has a pulley 1 at a position facing the center of canopy B.
1, and a pulley 7-2 is attached to a position near the support column 4-2 via hooks 8-1 and 8-2, respectively.

One end of the rope 9 is fixed to the winch 3, and the other end is placed above the canopy B through pulleys 7-1 and 7-2.

There are no particular restrictions on the attachment of the supports (1 and 2), and they may be fixed, for example, by dampening bolt holes or by overlaying them with the same material as the silo body A, such as unsaturated polyester resin.

There are no particular restrictions on the winch 3, and a commercially available manual winch is sufficient.

FIG. 3 shows a specific example of an airtight silo based on the present invention.

This airtight silo is constructed by attaching the support 1 of the canopy lifting device shown in Fig. 2 to the rib G of the manhole C, and the support 2 to the periphery of the peripheral wall plate E with bolts (15 and 16), respectively. .

The end of the rope 9 is tied to the handle F of the canopy B via an auxiliary rope 17.

In this airtight silo, the handle of the winch 3 is rotated and the rope 9 is wound around the canopy B to a position where it does not touch the silo body A (not shown).

) 1, and when the canopy B is pulled horizontally at that position, the struts 4-2 rotate and the canopy B moves horizontally, making it possible to load and unload silage into and out of the silo main body A.

When the canopy B is placed over the silo body A, the operation described above is reversed.

The airtight silo based on the present invention exhibits the following excellent effects.

When taking out silage from silo body A, or loading grass and meal into silo body A to prepare silage, canopy B must be removed or covered. The newly developed airtight silo allows this to be carried out safely with less effort and time.

Furthermore, since the structure of the canopy B lifting device is simple, it is inexpensive and extremely easy to operate.

Claims (1)

[Scope of utility model registration request] The manhole C' has a groove formed by molding the surrounding wall plate E along the outer peripheral edge of the cylindrical silo body A, and the end part of the canopy B is inserted into the groove to connect the canopy B to the silo body. At least two pulleys are attached to the hollow pipe-shaped support 4-1 to which the winch 3 is fixed, and the fiber-reinforced synthetic resin airtight silo is placed over A and injects liquid into the groove to isolate the silo body A from the outside. A support 4-2 to which a brim-like metal fitting 5 and an arm 6 having a truss beam structure are fixed is fitted into the support 4-2, making the support 4-2 freely rotatable.One end of the rope 9 is tied to the winch 3, and the other end is attached to the support 4-2. This airtight silo is equipped with a canopy lifting device by attaching a rope 9 to the silon main body A side by disposing a rope 9 so as to go around the canopy B through a pulley fixed to the cylon body A.
