Description

Upper closing device of a silo, for the transport of feed or granulated or powdery materials.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device upper closure of a silo tank, for the transport of granulated or powdery materials, which has been conceived and performed in order to obtain numerous and notable advantages over to other existing means of analogous purposes.

The device, with top covers, is provided for closing the upper opening of the silo, which serves for loading feed or granulated or powder materials. Well, the upper closing device is fixed on the part top of the silo and cover the entire surface of the opening of load.

Background of the invention

Various devices or means are known for the closing of the upper opening of the silo intended for loading the same.

In this sense the device of tarpaulins, attached with rubber, to the sides or on the roof, of the silo. This system has the disadvantage that the load of the vehicle, you have to remove the canvas aside, sometimes wet and broken, with danger to operator safety that Performs the operation and the time necessary for this purpose.

Description of the invention

The device of the invention has a new structure formed by two caps, right and left, which automatically close the silo load opening. He upper silo closure device can be operated by hydraulic, pneumatic or electronic circuit. He device exposed here is assisted by circuit hydraulic. The drive can be carried out with a distance. The upper silo closure device is attached to the silo through hinges or guides, which allow opening or closing desired by cylinders.

A silo is placed at the front of the silo electronic device to operate or stop the device upper closure of the silo.

The hydraulic cylinders are fixed by means of a support that is incorporated inside the silo.

A minimum of 2 to 8 sets of cylinders and corresponding supports, depending on the length of the upper silo closing device, depending on the load opening Let the silo arrange.

The most important advantages of this invention are:

?

Security for operators who carry out the work of loading and more ergonomic work.

?

Silo more tight and better protected the material to be transported.

?

Time saving at the moment of loading and unloading.

Brief Description of the Invention

Then it goes on to describe in a way very short a series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention presented as a non-limiting example of is.

Figure 1 is a perspective view of the vehicle.

Figure 2 is a closing mechanism view Top of a silo.

Figure 3 is a sectional view of the silo according to the cutting plane I-I.

Figure 4 is the circuit diagram hydraulic.

Preferred realization of the utility model

In figure 1 you can see a vehicle (semi-trailer) (1) incorporating a silo (2) for the transport of feed or granulated or powdery materials, equipped with a upper closing device (3) of the present utility model. The upper closing device (3) is placed covering all the loading opening (5) of the silo (2) and are fixed at the top of the silo (2) by hinges (6) or guides.

The mechanism is detailed in figure 2 electronic (4) acting on the circuit that incorporates (hydraulic, pneumatic or electronic) for opening or closing the upper closing device (4) of a silo (2).

Figure 3 shows a sectional view. I-I inside the silo (2) where a support (7) for anchoring hydraulic cylinders (8) that allow the opening or closing of the upper closing device (3) of the silo (2). These cylinders (8), in this case hydraulic, are connected by pipes (9) that are part of the circuit Hydraulic detailed schematically in Figure 4.

In figure 4 the circuit is schematized hydraulic that consists of a tank (10) located below the silo (2) and near the end of the body. The oil, through a pump (11), pipes (9) and a distributor valve (12), actuate the cylinders (8).
