Description

Technical Field

[0001] This utility model relates to the field of agricultural product transportation technology, specifically an agricultural product transportation and preservation device. Background Technology

[0002] As people's living standards improve, their demand for various fruits and vegetables is also increasing. Fresh fruits and vegetables from agricultural production bases need to be connected to urban markets through logistics channels. This logistics method generally uses road transport to ensure that fresh fruits and vegetables are delivered to supermarkets and other markets on time every day. After transportation, agricultural products can also be stored in transport containers.

[0003] However, during transportation, ordinary trucks are usually used for transport. In reality, the product breathes naturally, which continuously consumes the oxygen inside the truck. First, it undergoes normal aerobic respiration, and the ethylene inside naturally evaporates. Once the oxygen is depleted, it undergoes normal anaerobic respiration, which makes the inside of the truck stuffy and breeds anaerobic bacteria, making the product very susceptible to deterioration during transportation. Utility Model Content

[0004] The purpose of this invention is to provide a device for transporting and preserving agricultural products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0022] The gas supply port is fixedly installed on one side surface of the No. 1 gas storage tank and the No. 2 gas storage tank.

[0023] The gas supply pipe consists of two pipes, one end of which is connected to the other side of the No. 1 gas storage tank and the No. 2 gas storage tank, respectively.

[0024] A sealing valve is fixedly installed at the middle of the gas supply pipe inlet and at one end of the gas delivery pipe.

[0030] The power distribution box is fixedly installed on the rear edge of the upper surface of the box body, and the internal electrical control components of the power distribution box are interconnected with the power supply of the No. 1 solenoid valve and the No. 2 solenoid valve.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1. The transport compartment is installed and used as the cargo compartment of a transport truck. During transportation, agricultural products are placed inside the compartment, which is kept relatively sealed. During transportation, the drive motor rotates the blades inside the vacuum pump head, which extracts some of the air from inside the compartment and discharges it through the exhaust pipe, creating a low-oxygen, low-pressure gas environment. This achieves the effect of depressurized storage, promotes the diffusion and expulsion of gases such as ethylene from the fruits and vegetables, and enables ultra-long-term storage and preservation. While depressurizing and venting, nitrogen and a small amount of oxygen are injected into the compartment through the gas injection structure. The nitrogen displaces other components of the air and gases such as ethylene from the compartment, while the small amount of oxygen maintains a low-rate aerobic respiration of the agricultural products, achieving controlled atmosphere storage. By controlling the ratio of oxygen, carbon dioxide, and nitrogen inside the compartment, the respiration of the fruit and the production of ethylene are inhibited.

[0033] 2. The distribution box provides electrical control for solenoid valves No. 1 and No. 2. Solenoid valve No. 2 controls the opening and closing of the two gas supply pipes. At the same time, solenoid valve No. 1 adjusts the oxygen and nitrogen ratio gathered at the three-way pipe and injects it into the compartment through the gas injection pipe. This provides a certain degree of controllability to meet the storage needs of different agricultural products. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figure 1-5 In this embodiment of the present invention, an agricultural product transportation and preservation device includes a transport compartment 1, an air extraction structure 2, and an air injection structure 3. The transport compartment 1 includes a compartment body 101. The air extraction structure 2 includes a drive motor 201, which is fixedly installed on the rear edge of the upper surface of the compartment body 101. The output end of the drive motor 201 is fixedly connected to the blade inside the vacuum pump head 203. One side of the vacuum pump head 203 is connected to the interior of the compartment body 101 through an air extraction pipe 204. An exhaust pipe 205 is fixedly installed on the upper side of the vacuum pump head 203. The air injection structure 3 is fixedly installed on the rear side of the compartment body 101. An mounting plate 202 is fixedly installed on the bottom side of the drive motor 201, which is fixedly installed on the rear edge of the upper surface of the compartment body 101. A filter port 206 is screwed onto the upper end of the exhaust pipe 205.

[0042] Specifically, the transport compartment 1 is installed and used as the compartment of a transport truck. During transportation, agricultural products are placed inside the compartment 101, and the interior of the compartment 101 is kept relatively sealed. During transportation, the drive motor 201 rotates the blades inside the vacuum pump head 203, which extracts some of the air inside the compartment 101 and discharges it from the exhaust pipe 205, forming a low-oxygen, low-pressure gas environment to achieve depressurization storage. This promotes the diffusion and discharge of gases such as ethylene from the fruits and vegetables, achieving ultra-long-term storage and preservation. At the same time as depressurization and exhaust, nitrogen and a small amount of oxygen are injected into the compartment 101 through the gas injection structure 3. The nitrogen displaces other components of the air and gases such as ethylene from the compartment 101, while the small amount of oxygen maintains low-rate aerobic respiration of the agricultural products, achieving controlled atmosphere storage. By controlling the ratio of oxygen, carbon dioxide, and nitrogen inside the compartment 101, the respiration of the fruit and the generation of ethylene are inhibited.

[0043] Example 1

[0044] like Figure 2As shown, in this embodiment, the transport compartment 1 also includes an air extraction port 102, an air injection port 103, a sealed door 104, a sealing strip 105, and an elevated floor plate 106. The air extraction port 102 is located on the rear edge of the upper surface of the compartment 101, and the air extraction port 102 is connected to the lower end of the air extraction pipe 204. The air injection port 103 is located on the upper surface of the compartment 101. The elevated floor plate 106 is fixedly installed on the bottom side inside the compartment 101, and several ventilation slots 107 are evenly arranged and interspersed on the upper side of the elevated floor plate 106. There are two sealed doors 104, which are respectively hinged to the two sides of the opening of the compartment 101. The sealing strip 105 is fixedly embedded in the inner edge of the sealed door 104.

[0045] In this embodiment, the opening of the compartment 101 is sealed by the sealing door 104, and the sealing effect is improved by the sealing strip 105 to keep the interior of the compartment 101 relatively sealed. At the same time, a certain gap is created at the bottom of the compartment 101 by the overhead floor plate 106, and the upper and lower spaces are connected by various ventilation slots 107 to prevent agricultural products placed at the bottom of the compartment 101 from being affected by poor gas flow and thus affecting the storage effect.

[0046] like Figure 4 As shown, in this embodiment, the gas injection structure 3 includes a support base 301, a first gas storage tank 303, a second gas storage tank 304, a gas replenishment port 305, a gas delivery pipe 306, and a sealing valve 307. The support base 301 is fixedly installed on the lower rear edge of the compartment 101; the first gas storage tank 303 is fixedly installed on the upper surface of the support base 301 via a stabilizing bracket 302; the second gas storage tank 304 is fixedly installed on the upper surface of the first gas storage tank 303 via a stabilizing bracket 302; the gas replenishment port 305 is fixedly installed on one side surface of the first gas storage tank 303 and the second gas storage tank 304; there are two gas delivery pipes 306, one end of which is connected to the other side of the first gas storage tank 303 and the second gas storage tank 304 respectively; the sealing valve 307 is fixedly installed in the middle of the gas replenishment port 305 and one end of the gas delivery pipe 306.

[0047] In practice, nitrogen is stored in gas tank 303 and oxygen is stored in gas tank 304. The gas stored in gas tank 303 and gas tank 304 is replenished through gas supply port 305. During filling, the gas in the tank is discharged through gas supply pipe 306. At the same time, the closing and opening of gas supply port 305 and gas supply pipe 306 are manually controlled by sealing valve 307.

[0048] Example 2

[0049] Based on Example 1, in order to supplement the specific ratio of nitrogen and oxygen being simultaneously introduced into the compartment 101, which was not mentioned in Example 1, this method is proposed.

[0050] like Figure 5As shown, in this embodiment, the gas injection structure 3 also includes a three-way pipe 308, a first solenoid valve 309, a second solenoid valve 310, a gas injection pipe 311, and a power distribution box 312. The two ends of the three-way pipe 308 are respectively connected to the other ends of the two gas supply pipes 306. The first solenoid valve 309 is fixedly installed in the middle of the three-way pipe 308. The second solenoid valve 310 is fixedly installed at the other end of the two gas supply pipes 306. The rear end of the gas injection pipe 311 is connected to the front side of the three-way pipe 308, and the front end of the gas injection pipe 311 is connected to the gas injection port 103. The power distribution box 312 is fixedly installed on the rear edge of the upper surface of the box body 101, and the internal electrical control components of the power distribution box 312 are connected to the power supply of the first solenoid valve 309 and the second solenoid valve 310.

[0051] In practice, the power distribution box 312 electrically controls the first solenoid valve 309 and the second solenoid valve 310. The second solenoid valve 310 controls the opening and closing of the two gas supply pipes 306. At the same time, the first solenoid valve 309 adjusts the oxygen and nitrogen ratio gathered at the three-way pipe 308 and injects it into the compartment 101 through the gas injection pipe 311. This provides a certain degree of controllability to meet the storage needs of different agricultural products.
