Problems solved by technology

B. Afterwards, take out the deinsectized grains from the pressure-resistant container W and transport them through the lower conveyor belt mechanism 3 and store them in the grain warehouse. It adopts pressure-changing deinsectization, has no drug residues, and is environmentally friendly, but it is only A pest control measure before grain storage cannot guarantee other conditions of grain storage, and the use of pressure-resistant containers has high manufacturing costs and cannot achieve long-term high-quality storage of grain

Embodiment 1

[0019] Embodiment one: see figure 1 , in the figure, the hollow grain storage bin body 2 of the grain vacuum storage device is a circular vertical bin body, and its upper and lower ends are respectively provided with an inlet bin and an outlet bin, and the inlet bin and the outlet bin are respectively A sealing cover (not shown in the figure) is provided, the lower end of the hollow grain storage bin body 2 is provided with a support 1, and a flexible bag body 3 is set in the inner cavity of the hollow grain storage bin body 2, and the size and shape of the flexible bag body 3 are the same as those of the hollow grain storage bin body. The inner cavity of the grain storage silo body 2 is matched, and the flexible bag body 3 is respectively provided with an inlet pocket and an outlet pocket. The silo mouth is corresponding, which is convenient for feeding in and out of the material, and a sealing mechanism (not shown in the figure) is respectively arranged on the feeding bag mo...

Embodiment 2

[0023] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the hollow grain storage bin body 2 is a room-shaped horizontal bin body, and its feeding bin is arranged on the upper slope. Its discharge bin is arranged on the side of the lower part.

Embodiment 3

[0024] Embodiment 3: This embodiment is basically the same as Embodiment 2, and the similarities will not be repeated. The difference is that there are more than one flexible bag (can be two, three, four or more, determined according to needs) ), and the quantity of the feed bin and the discharge bin on the hollow grain storage silo is consistent with the quantity of the flexible bag body, so that the feed bag and the discharge bag provided on each flexible bag are all consistent with an inlet The feed bin port corresponds to the discharge bin port.

Abstract

The invention discloses a set of vacuum storage equipment of a grain: an inner cavity of a hollow grain storage silo body is sleeved with a flexible bag body, the size and shape of which are matched with the inner cavity of the hollow grain storage silo body. A bag inlet and a bag outlet arranged on the flexible bag body are corresponding to a silo inlet and a silo outlet arranged on the hollow silo. The bag inlet and the bag outlet are respectively provided with a sealing mechanism. The upper part at the outer surface of the flexible bag body is connected with the upper part of the inner cavity of the hollow grain storage silo body by a flexible cable; furthermore, a flexible vacuum-pumping pipe is arranged on the flexible bag body and the inner end of the vacuum-pumping pipe is communicated with the flexible bag body and the outer end thereof is communicated with a set of vacuum-pumping equipment. The invention has simple structure, novel design, convenient use and wide application range, can effectively keep the quality of the grain stored in a long term, reaches environment friendly standard as well and is beneficial to the health of eaters, thus having good economic and social benefits.

Description

1. Technical field: [0001] The invention relates to a grain storage device, in particular to a grain vacuum storage device. 2. Background technology: [0002] my country is a large agricultural country, and the output of grain is huge. If it is not stored well, it will deteriorate. Among them, the safe long-term high-quality storage of grain requires three elements: 1. Reasonable and safe moisture: the general moisture content is 14% (depending on the variety and region) There are some differences), higher than this safe moisture content, grains are prone to mildew, and the lower the moisture content, the better for long-term storage. Every 1% reduction in moisture content can prolong the storage life by 1-3 years. 2. Appropriate storage temperature: the lower the temperature, the better, because the oxidation of grains will be accelerated under high temperature, and the pests and diseases will also intensify. 3. Appropriate oxygen partial pressure: The lower the oxygen part...
