Description

Technical Field

[0001] This invention relates to the field of wheat seeds, and more specifically, to a low-temperature rapid micro-freezing storage device for wheat seeds. Background Technology

[0002] Wheat is a cereal crop widely cultivated around the world. Wheat grains are a staple food for humans, and when ground into flour, they can be used to make bread, steamed buns, biscuits, noodles, and other foods. Before sowing, wheat seeds need to be stored at low temperatures using micro-freezing equipment to effectively preserve the activity of the seed embryo. However, most current micro-freezing equipment only has a box and lid to seal the wheat inside. Traditional sealing methods use rubber rings, which are susceptible to temperature changes. In low-temperature environments, gaps can easily form at the seal, affecting the internal temperature of the storage device and making the seeds more vulnerable to bacterial contamination, thus reducing their efficiency. Therefore, we have proposed an improved low-temperature rapid micro-freezing storage device for wheat seeds. Summary of the Invention

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

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0005] A low-temperature rapid micro-freezing storage device for wheat seeds includes a box body and a box lid hinged to the top of the box body. The box body has a low-temperature cavity inside for storing the box inside.

[0006] The surface of the box lid is provided with an outer sealing airbag and an inner sealing airbag respectively. The box body has an outer sealing groove at the position corresponding to the outer sealing airbag, and the storage box has an inner sealing groove at the position corresponding to the inner sealing airbag.

[0007] The surface of the box cover is provided with an external pressurization mechanism and an internal pressurization mechanism corresponding to the positions of the outer sealing airbag and the inner sealing airbag, respectively.

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

[0009] The pressurizing part includes a pressurizing chamber formed inside the lid, a pressurizing piston slidably disposed in the pressurizing chamber, and a connecting rod connected to one side of the pressurizing piston.

[0010] As a preferred technical solution of this application, the pressurizing part further includes a support plate fixed to the middle of one side of the box cover, a transmission plate slidably disposed 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 this application, both ends of the transmission plate are connected to telescopic plates, and a housing that is fixed to the box cover is slidably sleeved on the surface of the telescopic plates;

[0012] The telescopic plate extends toward the interior of the box and has a connecting portion for fixing to the end of the corresponding connecting rod.

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

[0014] The locking part also includes a locking seat, which is fixed to the outside of the box and is correspondingly arranged with the locking arm.

[0015] As a preferred technical solution of this application, the surface of the locking arm has a groove, and pulling the locking arm outward can cause the groove to engage with the locking buckle on the locking seat to form a lock on the box cover.

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

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

[0018] As a preferred technical solution of this application, a cooler is installed on the back of the box, and the cooler has a cooling pipe, one end of which extends into the low-temperature cavity for low-temperature cooling.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the scheme of this application:

[0021] 1. By coordinating the outer and inner sealing airbags, when the lid is fastened to the box body for micro-freezing storage of wheat in the low-temperature chamber, the outer and inner sealing airbags are in a semi-inflated state to ensure their embedding and sealing with the corresponding outer and inner sealing grooves. Subsequently, the transmission plate can be pushed to extend the telescopic plate on it outward. During the extension process, the pressure piston on the connecting plate can be driven to slide in the pressure chamber through the connecting part, promoting the pressurization of the inner and outer sealing airbags and making them in a full state. The inner and outer sealing airbags in the full state not only ensure their stable embedding in the outer and inner sealing grooves and prevent them from loosening, but also can be adaptively compensated by pressurized gas when affected by the low temperature environment inside the box body to ensure the sealing effect.

[0022] 2. By setting up external and internal pressurization mechanisms, after the connecting plate is pushed to pressurize the inner and outer sealing airbags, the locking arm is flipped so that its buckle groove engages with the locking seat, thereby completing the connection between the box body and the box cover. This ensures that the box cover is securely fastened while also achieving a sealing effect on the box body. Attached Figure Description

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Please see Figures 1 to 7 The present invention provides a technical solution: a low-temperature rapid micro-freezing storage device for wheat seeds, including 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 for placing a storage box 12 inside it;

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

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

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

[0048] The pressurizing part also includes a support plate 34 fixed to the middle of one side of the cover 2, a transmission plate 35 slidably disposed 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 telescopic plates 350. A housing 351 fixed to the box cover 2 is slidably sleeved on the surface of the telescopic plate 350. The telescopic plate 350 extends toward the inside of the box body 1 and has a connecting part 352 for fixing to the end of the corresponding connecting rod 33.

[0050] In its 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 sub-filled 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 inner sealing groove 14 during the process of flipping and closing the box cover 2, thereby forming a sealed protection for the inside of the box body 1.

[0051] In actual application, since the inside of the box 1 needs to be refrigerated at low temperature for storing wheat, the outer sealing airbag 21 and the inner sealing airbag 22 will shrink to a certain extent when subjected to low temperature, which will easily create a sealing gap between them and the corresponding outer sealing groove 13 and inner sealing groove 14, thus which is not conducive to the stable sealing effect inside the box 1. Therefore, in this embodiment, the outer pressure mechanism 3 and the inner pressure mechanism 4 are set.

[0052] Specifically, after the inner sealing airbag 22 and outer sealing airbag 21 in the sub-filled state are embedded and sealed with the corresponding outer sealing groove 13 and inner sealing groove 14, 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 plate 33 below through the connecting part 352. Therefore, the connecting part 352 will push the connecting plate 33 and the pressurizing piston 32 on it to slide in the pressurizing chamber 31. After the pressurizing chamber 31 is subjected to the sliding action, it will generate pressurized gas and input it into the corresponding outer sealing airbag 21 and inner sealing airbag 22, so that it changes from the sub-filled state to the full state. In this way, when subjected to low temperature, even if the outer sealing airbag 21 and 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 inner sealing groove 14 under the action of the internal pressurized gas, ensuring stable low temperature storage of wheat.

[0053] The locking part includes a movable groove 36 opened at one end of the telescopic plate 350, and a locking arm 37 is hinged in the movable groove 36. The locking part also includes a locking seat 38, which is fixed to the outside of the box body 1 and is correspondingly arranged with the locking arm 37.

[0054] The surface of the locking arm 37 has a latching groove 370. Pulling the locking arm 37 outward can cause the latching groove 370 to engage with the locking buckle 380 on the locking seat 38 to lock the lid 2.

[0055] After the aforementioned push transmission plate 35 is in the appropriate position, the locking arm 37 on the flip telescopic plate 350 can be flipped so that the buckle groove 370 on it engages with the corresponding locking buckle 380, thereby realizing the gas pressurization of the outer sealing airbag 21 and the inner sealing airbag 22, while also locking the box cover 2, thus improving its practicality.

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

[0057] Since the inner sealing airbag 22 and the outer sealing airbag 21 are spaced apart, if an accident causes the seal between the outer sealing airbag 21 and the box 1 to fail, the inner sealing airbag 22 and the storage box 12 will still be effectively sealed, thus greatly improving the stability of the device.

[0058] A cooler 5 is installed on the back of the box 1. The cooler 5 has a cooling pipe 51. One end of the cooling pipe 51 extends into the low-temperature cavity 11 for low-temperature cooling. When the cooler 5 is activated, the air in the low-temperature cavity 11 can be cooled through the cooling pipe 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 by the action of the low-temperature cavity 11. At the same time, the cooling gas is prevented from directly contacting the wheat and causing frostbite.

[0059] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
