Description

The utility model relates to agriculture, namely to fodder production - preparation and storage of silage feed.

A device is known for block-vacuum siloing of feeds, containing a trench buried in the soil, in which green feed, a polyethylene silo film, perforated pipes for pumping air, a common collector and perforated pipes for pumping juice are laid, while the polyethylene silo film consists of two panels, the lower of which is laid on the bottom, the side and end walls of the trench, forming a silo storage tank, and the upper panel is laid on top of the green feed, forming the lid of this tank, perforated pipes For air pumping, they are located in the trench above the level of juice formed in the green feed during lactic acid fermentation, the common collector is equipped with a shut-off valve and a nozzle for connection to the vacuum pump, and perforated pipes for pumping the juice are located at the bottom of the tank, and the silo storage tank consists of of three isolated bag compartments located along the length of the trench, and the upper panel consists of three parts forming the covers of these bag compartments, while the edges of the covers are hermetically connected to at least one perforated pipe for pumping air and at least one perforated pipe for pumping juice, interconnected by a connecting pipe, the end of which is removed from the trench above the level soil, equipped with a shut-off valve and connected to the ends of the connecting pipes of other compartments-bags through a common collector (RU 136951, IPC A01F 25/16, publ. 01/27/2014). The use of the known device to some extent increases the safety of the silo through the use of sealing. But during the selection of the silo from the trench, the plastic film has to be torn or cut, and re-sealing using the same film is almost impossible, which negatively affects the safety of the silo remaining in the trench. Further transportation of the selected silo to the feeding points is carried out in bulk, which also sharply reduces its safety, shortens the feeding time, and makes it impossible to store the silage removed from the trench for a long time even after insignificant distances.

The closest in technical essence to the proposed is the device described in the patent of the Russian Federation for invention No. 2584026 "Method for the preparation and storage of silage feed". It is intended to implement the method described in the aforementioned patent and is “... a soft container with an open neck made of an airtight film. In the lower part, the container has a non-return valve that does not let air into the container ”(RU 2584026, IPC A01F 25/14, publ. 05.20.2016, p. 6, first paragraph). Thanks to the preparation and storage of the silo in a soft container, it becomes possible to transport the silo in a container without violating its tightness, which to some extent increases the safety of the silo compared to non-transportable analog devices. But the known device has a number of significant disadvantages, the main of which are:

- the need to tear or cut the airtight shell of the soft container at each selection of a portion of the silo, which can lead to damage to the shell with the inability to repeatedly reseal the soft container, which reduces the safety of the remaining silo during its further storage;

- the lack of the possibility of continuous (rather than periodic) removal of silage juice, which creates favorable conditions for the development of harmful butyric acid bacteria in it. For example, butyric bacteria of the genus Clostridium develop in a silo with high humidity, which leads to a decrease in the safety of the silo and its subsequent damage [Laptev, G.Yu. Silage of feed with high humidity / G.Yu. Laptev / Agricultural News, 2007. - No. 2 (69)].

The main fundamental differences of the proposed soft container for the preparation and storage of silage from existing analogues are the following:

1) the soft container for preparing and storing the silo in the neck contains an airtight fastener, which ensures quick and technological opening of the soft container, eliminating the need to tear or cut the hermetic shell of the soft container at each selection of a portion of the silo (which can lead to damage to the shell with the impossibility of re-sealing) , and provides the possibility of repeated re-sealing of the container, thereby increasing the safety of the remaining silo during its further storage;

2) the soft container for preparing and storing the silo has two cavities located one above the other with the possibility of communication with each other, which creates the prerequisites for reducing the silo moisture (due to the constant removal of silage juice into a separate cavity), thereby preventing the development of harmful ones in it butyric acid bacteria, which ultimately aims to increase the safety of the silo during storage;

3) two cavities are located one above the other with the possibility of communication between each other and with the environment through a multi-mode spool valve, which ensures the implementation of the following operating modes: evacuation of both cavities of a soft container, gravity draining from the upper cavity to the lower cavity by gravity, maintaining the integrity of the upper cavity ( in which the silo is stored) during periodic removal (pumping) of silage juice from the lower cavity of the soft container, thereby eliminating the access of air to the silo when removing ka from the container and increasing the safety of the silo during storage.

The objective of the proposed utility model is to increase the efficiency of preparation and storage of silage in soft vacuum packaging.

The technical result of the utility model is to increase the safety of the silo during its preparation and storage in soft vacuum packaging.

The technical result is achieved in that the soft container for preparing and storing the silo contains a neck and an opening with a check valve, an airtight fastener in the neck, has two cavities located one above the other, with the possibility of communication with each other and with the environment through a multi-mode spool valve.

The soft container for preparing and storing the silo contains a neck 7 and an opening with a check valve 8, an airtight fastener 2 in the neck 7, has two cavities 1 and 3, located one above the other, with the possibility of communication with each other and with the environment through a multi-mode spool valve 4 The multi-mode spool distributor 4 has a housing 17 with a spool 9, which is installed between the springs 10 and 11. Inside the spool 9, a central channel 12 is made to create a vacuum and pump silage juice. The distributor housing 17 is connected to the upper cavity 1 by a nozzle 13 for evacuation and a nozzle 14 for draining the silage juice, and with a lower cavity by a nozzle 15 for evacuation and a nozzle 16 for pumping silage juice. The distributor housing 17 is connected to the environment by a vacuum pipe 5 (via a check valve 8) and an air pipe 6.

The proposed utility model is illustrated by the schemes:

FIG. 3 - multi-mode spool valve in the mode of evacuation and pumping of silage juice;

FIG. 4 - multi-mode spool dispenser in the mode of discharge of silage juice "gravity".

The device operates as follows. The silage mass through the neck 7 is loaded into the upper cavity 1 and the airtight fastener 2 is closed (Fig. 1). By connecting the vacuum pipe 5 through the check valve 8 to a vacuum pump (not shown) create a vacuum in the cavity of the housing 17 (Fig 2). Due to the difference in atmospheric pressure on the one hand and vacuum on the other hand, the spool 9 is shifted to the right and gives access to the pipes for evacuation 13 and 15, opening the channel between the cavities 1 and 3 (Fig 3). The air and the gases generated during the silo are pumped out through the central channel 12 of the spool 9. Upon reaching the required pressure, the vacuum pump is turned off and the spool 9 returns to the neutral position, blocking the communication between the upper and lower cavities 1 and 3 (Fig. 2).

To drain the silage juice, the air pipe 6 is connected to a vacuum pump, due to the pressure difference in the pipes 5 and 6, the spool 9 is shifted to the left, opening the channel between the upper and lower cavities 1 and 3 (Fig. 4), due to the groove in the spool 9. Given that in both cavities the same value of vacuum pressure, under the influence of gravity, the silage juice flows into the lower cavity 3 through the nozzle for draining the silage juice 14 and the nozzle for pumping the silage juice 16. Having closed the air nozzle 6, the silo juice can be drained for a long period without spending energy on pumping it out.

With the accumulation of silage juice in the lower cavity 3, the vacuum pump with the receiver (not shown) is connected to the vacuum pipe 5. Due to the difference in atmospheric pressure on the one hand and the vacuum pressure on the other hand, the spool 9 is shifted to the right (Fig 3) and gives access to a branch for pumping silage juice 16. Silage juice from the lower cavity 2 is pumped out through the central channel 12 of the spool 9. Due to the displacement of the spool 9, the groove connects the nozzles for evacuation 13 and 15, forming a channel, and the vacuum pressure is equal in ag ood sort cavities 1 and 3. At the end of the vacuum pump suction is switched off and the valve 9 is returned to the neutral position (Figure 2), blocking communication between the upper and lower cavities 1 and 3.

The use of the proposed soft container improves the efficiency of preparation and storage of silage in a soft vacuum packaging by increasing its safety. This device is universal and can be used in the preparation and storage of any silage feed.
