Description

Technical Field

[0001] The invention relates to the field of wheat seeds, and in particular to low-temperature rapid micro-freezing storage equipment for wheat seeds. Background Art

[0002] Wheat is a cereal crop widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. Before sowing, wheat seeds need to be cooled and stored in a micro-frozen storage device to effectively ensure the activity of the seed embryo. However, most of the general micro-frozen storage devices currently only have a box body and a lid to cover the wheat inside to form a sealed storage. However, since the traditional seal uses a rubber ring, the rubber ring itself will change due to the influence of temperature, which is easy to cause gaps in the seal under low temperature conditions and affect the temperature inside the storage device. It is also easy for the seeds to be infected with external bacteria, reducing its use efficiency. Therefore, we have made improvements to this and proposed a low-temperature rapid micro-frozen storage device for wheat seeds. Summary of the invention

[0003] The purpose of the present invention is to provide a low-temperature rapid micro-freezing storage device for wheat seeds. By arranging an external pressure mechanism and an internal pressure mechanism, the problem that a traditional sealing rubber ring is easily affected by an external low-temperature environment and produces a sealing gap is solved.

[0004] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0005] A wheat seed low-temperature rapid micro-freezing storage device comprises a box body and a box cover hinged to the top of the box body, wherein the interior of the box body has a low-temperature cavity for placing a storage box therein;

[0006] The surface of the box cover is provided with an outer sealing airbag and an inner sealing airbag respectively, the box body is formed with an outer sealing groove at a position corresponding to the outer sealing airbag, and the storage box is formed with an inner sealing groove at a position corresponding to the inner sealing airbag;

[0007] An external pressurizing mechanism and an internal pressurizing mechanism are respectively arranged on the surface of the box cover at positions corresponding to the external sealing airbag and the internal sealing airbag.

[0008] As a preferred technical solution of the present application, the external pressure mechanism includes a locking part and a pressure part;

[0009] The pressurizing part comprises a pressurizing cavity formed inside the box cover, a pressurizing piston slidably arranged in the pressurizing cavity and a connecting rod connected to a side surface of the pressurizing piston.

[0010] As a preferred technical solution of the present application, the pressure-applying part also includes a support plate fixed to the middle of one side of the box cover, a transmission plate slidably arranged in the support plate, and a spring connected to the middle of one side of the transmission plate and fixed to the support plate.

[0011] As a preferred technical solution of the present application, both ends of the transmission plate are connected to telescopic plates, and a housing fixed to the box cover is provided on the surface sliding sleeve of the telescopic plate;

[0012] Wherein, the telescopic plate has a connecting portion extending toward the interior of the box body for fixing with the corresponding end of the connecting rod.

[0013] As a preferred technical solution of the present application, the locking portion includes a movable groove opened at one end of the telescopic plate, and a locking arm is hinged in the movable groove;

[0014] Wherein, the locking part also includes a locking seat, which is fixed to the outside of the box body and is arranged corresponding to the locking arm.

[0015] As a preferred technical solution of the present application, the surface of the locking arm has a buckle groove, and the locking arm is pulled outward and the buckle groove can be buckled into the locking buckle on the locking seat to lock the box cover.

[0016] As a preferred technical solution of the present application, the external pressurizing mechanism and the internal pressurizing mechanism have the same structure;

[0017] The pressurizing chamber in the external pressurizing mechanism is connected to the external sealing airbag through an external pressurizing pipe, and the pressurizing chamber in the internal pressurizing mechanism is connected to the internal sealing airbag through an internal pressurizing pipe.

[0018] As a preferred technical solution of the present application, a refrigerator is installed on the back of the box body, and a refrigeration tube is provided on the refrigerator, and one end of the refrigeration tube extends into the low-temperature cavity for low-temperature refrigeration.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the scheme of this application:

[0021] 1. Through the cooperation of the outer sealing airbag and the inner sealing airbag, when the box cover is buckled on the box body to slightly freeze the wheat in the low-temperature chamber, the outer sealing airbag and the inner sealing airbag are in a secondary filling state to meet the embedding and sealing between the outer sealing groove and the inner sealing groove. After that, the transmission plate can be pushed to extend the telescopic plate on it outward. During the extension process, the pressurizing piston on the connecting plate can be driven to slide in the pressurizing chamber through the connecting part, so as to promote the pressurization of the inner sealing airbag and the outer sealing airbag to be in a filled state. The inner sealing airbag and the outer sealing airbag in the filled state can meet the requirements of being embedded in the outer sealing groove and the inner sealing groove stably and not easy to loosen. At the same time, when affected by the low temperature environment inside the box body, they can be adaptively compensated by the pressurized gas to ensure the sealing effect.

[0022] 2. By setting up the external pressure mechanism and the internal pressure mechanism, after pushing the connecting plate to pressurize the inner sealing airbag and the outer sealing airbag, the locking arm is flipped so that the buckle groove on it is buckled on the locking seat, thereby completing the connection between the box body and the box cover. In this way, while ensuring the stable buckling of the box cover, the sealing effect of the straight body is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0044] See also Figures 1 to 7 The present invention provides a technical solution: a low-temperature rapid micro-freezing storage device for wheat seeds, comprising a box body 1 and a box cover 2 hinged to the top of the box body 1, wherein the box body 1 has a low-temperature cavity 11 inside for placing a storage box 12 therein;

[0045] The surface of the box cover 2 is provided with an outer sealing airbag 21 and an inner sealing airbag 22, respectively; the box body 1 is provided with an outer sealing groove 13 at a position corresponding to the outer sealing airbag 21, and the storage box 12 is provided with an inner sealing groove 14 at a position corresponding to the inner sealing airbag 22;

[0046] The surface of the box cover 2 is provided with an external pressurizing mechanism 3 and an internal pressurizing mechanism 4 at positions corresponding to the external sealing airbag 21 and the internal sealing airbag 22 respectively;

[0047] The external pressurizing mechanism 3 includes a locking part and a pressurizing part, wherein the pressurizing part includes a pressurizing chamber 31 formed inside the box cover 2, a pressurizing piston 32 slidably disposed in the pressurizing chamber 31 and a connecting rod 33 connected to a side surface of the pressurizing piston 32;

[0048] The pressurizing part further includes a support plate 34 fixed to the middle of one side of the box cover 2, a transmission plate 35 slidably arranged in the support plate 34, and a spring 39 connected to the middle of one side of the transmission plate 35 and fixed to the support plate 34;

[0049] Both ends of the transmission plate 35 are connected to a telescopic plate 350, and a housing 351 fixed to the box cover 2 is slidably sleeved on the surface of the telescopic plate 350, wherein the telescopic plate 350 has a connecting portion 352 extending toward the inside of the box body 1 for fixing with the corresponding end of the connecting rod 33;

[0050] In the natural state, the outer sealing airbag 21 and the inner sealing airbag 22 are filled with gas, and under the action of the gas, the outer sealing airbag 21 and the inner sealing airbag 22 are in a secondary filling state. In this state, the outer sealing airbag 21 and the inner sealing airbag 22 can be embedded and assembled with the corresponding outer sealing groove 13 and the inner sealing groove 14 during the process of the box cover 2 being turned over and closed, thereby forming a sealed protection for the inside of the box body 1;

[0051] In actual application, since the box body 1 needs to be cooled at low temperature to store wheat, the outer sealing airbag 21 and the inner sealing airbag 22 will shrink to a certain extent when subjected to low temperature, so that a sealing gap is easily generated between the corresponding outer sealing groove 13 and the inner sealing groove 14, which is not conducive to the stable sealing effect inside the box body 1. For this reason, the outer pressurizing mechanism 3 and the inner pressurizing mechanism 4 are provided in this embodiment;

[0052] Specifically, after the inner sealing airbag 22 and the outer sealing airbag 21 in the sub-filled state are embedded and assembled with the corresponding outer sealing groove 13 and the inner sealing groove 14 to complete the sealing, the transmission plate 35 can slide on the surface of the box cover 2. The transmission plate 35 in the sliding state will drive the telescopic plates 350 on both sides to move synchronously. The telescopic plates 350 are connected to the corresponding connecting plates 33 below through the connecting parts 352. Therefore, the connecting parts 352 will push the connecting plates 33 and the pressurizing pistons 32 thereon to slide in the pressurizing chamber 31. After the pressurizing chamber 31 is subjected to the sliding action, pressurized gas will be generated and input into the corresponding outer sealing airbag 21 and the inner sealing airbag 22, so that the pressurizing chamber 31 changes from the sub-filled state to the filled state. In this way, when subjected to low temperature, even if the outer sealing airbag 21 and the inner sealing airbag 22 will shrink to a certain extent, they will form a stable sealing state with the corresponding outer sealing groove 13 and the inner sealing groove 14 under the action of the internal pressurized gas, thereby ensuring the stable low-temperature storage of wheat.

[0053] The locking part includes a movable groove 36 formed at one end of the telescopic plate 350, and a locking arm 37 is hinged in the movable groove 36, wherein the locking part also includes a locking seat 38, and the locking seat 38 is fixed to the outer side of the box body 1 and is arranged corresponding to the locking arm 37;

[0054] The surface of the locking arm 37 has a buckle groove 370, and the locking arm 37 is pulled outward to make the buckle groove 370 buckle with the locking buckle 380 on the locking seat 38 to lock the box cover 2;

[0055] After the driving plate 35 is pushed to a suitable position, the locking arm 37 on the telescopic plate 350 can be turned over to make the buckle groove 370 on the locking buckle 380 engage with the corresponding locking buckle 380, thereby achieving gas pressurization of the outer sealing airbag 21 and the inner sealing airbag 22, and locking the box cover 2, thereby improving its practicality.

[0056] like Figure 7 As shown, the structures of the external pressurizing mechanism 3 and the internal pressurizing mechanism 4 are the same. The pressurizing chamber 31 in the external pressurizing mechanism 3 is connected to the external sealing airbag 21 through an external pressurizing pipe, and the pressurizing chamber in the internal pressurizing mechanism 4 is connected to the internal sealing airbag 22 through an internal pressurizing pipe;

[0057] Since the inner sealing airbag 22 and the outer sealing airbag 21 are arranged at intervals, if an accident occurs and the seal between the outer sealing airbag 21 and the box body 1 fails, the inner sealing airbag 22 and the storage box 12 are still effectively sealed, thereby greatly improving the use stability of the device;

[0058] A refrigerator 5 is installed on the back of the box body 1. The refrigerator 5 has a refrigeration tube 51. One end of the refrigeration tube 51 extends into the low-temperature cavity 11 for low-temperature refrigeration. When the refrigerator 5 is started, the air in the low-temperature cavity 11 can be cooled through the refrigeration tube 51. Since the storage box for storing wheat is located in the low-temperature cavity 11, the wheat in the storage box 12 can be cooled through the action of the low-temperature cavity 11, while avoiding direct contact between the refrigeration gas and the wheat to cause frostbite.

[0059] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
