Description

The invention relates to devices for the mechanization of agricultural production, in particular to devices for the storage of agricultural products.

A device for storing agricultural products is known, comprising a shaft with side walls and a base, above which a motorized drive platform and a perforated tray are installed, inlet ventilation.

It is also known a technical solution, which is a device for storing agricultural products, comprising a shaft with side walls, a base on which a movable perforated tray and a perforated driven platform, an inlet ventilation system and a discharge conveyor are installed.

A disadvantage of the known devices is the complexity of the design, the need for significant labor costs, the possibility of injury to the material during loading, for example, during the storage of potatoes, vegetables and fruits.

The purpose of the invention is to reduce product losses from injury and increase productivity.

The goal is achieved by the fact that the loading and unloading of products is carried out in a mechanized manner, with the movable platform at the beginning of loading occupying the upper extreme position, which excludes product traumatizing when it falls after the conveyor.

The drawing shows the proposed device for storing agricultural products, a longitudinal section: a - when fully unloaded (or ready to receive a new product).

The device for storing agricultural products comprises a shaft with side walls 1 and a base 2, over which a movable platform 3 is installed, driven by a source of hydraulic system. It has a perforated bell with a curved surface over which cavity 6 is delighted to store agricultural products. On base 2, a screwdriver air supply 7 is made. Moreover, the working surface 5 of the movable platform 3 is formed by the movement of concave curves relative to the axis of symmetry and oriented with the lowest point to the level of the base of the discharge ports 9.

The movable platform is equipped with a drive mechanism made in the form of a hydraulic cylinder 4. In the upper part of the walls 1 there are windows 9, intended for unloading material, which are closed (at the moment of filling) with valves 10. On the outer sides of the shaft, opposite the windows 9, there are belt conveyors 11. The shaft has a cap-cover 12, equipped with holes 13, through which exhaust air is drawn through the exhaust channel 14. The working process proceeds as follows. In order to unload the agricultural products stored in the storage, the conveyor belts 11 are turned on, the valves 10 are opened.

Using the distributor, the oil is fed into the pressure cavity of the telescopic hydraulic cylinder 4. The movable platform 3 rises and through the windows 9 by gravity the material begins to pour onto the conveyor belt 11. After unloading, the cap-cover 12 is opened and measures are taken to prepare the storage for receiving a new batch of products for storage.

In order to carry out the loading, the movable platform 3 is raised to its upper position (see drawing, left shaft). Window

9 are closed with valves 10. With the help of the conveyor 15, the material enters the mine and falls from the allowable height established by the agro demands.

filling the cavity of the mine above the platform 3, it gradually goes down, increasing the working cavity 6.

Thus, the filling process ends when platform 3 takes its

lower position. The cap-lid 12 is closed and the ventilation process begins. In this case, the air through the duct 8 enters through the perforation of the hood of the platform 3 into the cavity of the food storage. For

increased ventilation can be turned on and exhaust ventilation. At the same time, due to the rational form of the cap, stable heat-air storage of the product within the specified parameters is provided.

The economic effect is achieved by reducing product losses during storage from injury and optimal maintenance of the heat-air regime.

storage, as well as by reducing labor costs when unloading products and increasing productivity.
