Technical Field

[0001] This invention relates to the field of vegetable preservation technology, and in particular to a device and method for preserving and storing vegetables during cultivation. Background Technology

[0002] Vegetable preservation and fresh storage refers to the process of using scientific technologies and equipment to slow down the post-harvest physiological metabolism of vegetables (such as respiration, transpiration, aging and deterioration) and inhibit the growth and reproduction of microorganisms, thereby maintaining the freshness, nutritional components, flavor and commercial quality of vegetables.

[0003] In existing technologies, after vegetables are harvested, they need to be placed in a pre-cooling warehouse to remove field heat, and then sent to a spraying room to spray preservatives (chlorine dioxide preparations or peracetic acid). After the excess preservatives on the vegetables have dried, the vegetables are then placed in a cold storage for storage, which extends the storage time of the vegetables.

[0004] However, in the existing technology, after the vegetables are harvested, they need to be transferred to the pre-cooling room, spray room and cold storage in sequence, which takes a long time and results in low efficiency in preserving and storing vegetables. Summary of the Invention

[0027] This invention provides a device for preserving and storing vegetables, including a preservation mechanism. The preservation mechanism comprises a windbox 102, a flow guide assembly, two air supply assemblies, two secondary air guide plates 114, a primary air guide plate 113, a conical air guide hood 103, a spray box 133, a spray assembly, a mounting platform 101, two slide rails 132, four sliders 131, a mounting frame 121, a placement rack 122, a wire mesh cage 123, four partitions 124, a toothed plate 116, and a drive assembly. The secondary air guide hood 128 has multiple through slots 115, and the drive assembly... The components include a fixed frame 117, a drive motor 118, a drive shaft 119, and a drive gear 120. The air supply component includes a mounting cylinder 104, a support frame 105, a rotary motor 107, a rotary shaft 108, multiple fan blades 109, an externally threaded cylinder 110, an internally threaded cylinder 111, and a filter plate 112. The support frame 105 has a ventilation slot 106. The spraying component includes a water pump 125, an annular water pipe 126, and multiple spray heads 127. The flow guiding component includes a flow guide shroud 128, a water outlet pipe 129, and a valve 130.

[0028] In this embodiment, two air supply components are respectively disposed at both ends of the air box 102, and the spraying component is disposed on the spray box 133. Two slide rails 132 are fixedly connected to the mounting platform 101, the air box 102, and the spray box 133 respectively, and pass through the air box 102 and the spray box 133. The air box 102 is located between the mounting platform 101 and the spray box 133. Four sliders 131 are fixedly connected to both ends of the mounting frame 121 respectively, and the four sliders 131 are slidably connected to the two slide rails 132 respectively, and are located above the two slide rails 132. The frame 122 is fixedly connected to the mounting frame 121 and located within the mounting frame 121. The net box 123 is adapted to the mounting frame 121. The toothed plate 116 is fixedly connected to the mounting platform 101, the bellows 102, and the spray box 133, and passes through the bellows 102. The driving component is located at one end of the mounting frame 121. When using this invention to preserve the freshness of vegetables, freshly picked vegetables are neatly placed in the net box 123. The driving component drives the mounting frame 121 and the net box 123 to move into the bellows 102 until the net box 123 moves into the bellows 102. The two air supply components are activated, supplying cold air into the air box 102. The cold air flows rapidly among the vegetables, quickly carrying away their heat and eliminating field heat. Then, the drive component is activated again, moving the net box 123 and the mounting frame 121 towards the spray box 133. Once the net box 123 is inside the spray box 133, the drive component is shut off, and the spray component is activated. The spray component atomizes the preservative, and the water mist containing the preservative permeates the spray box 133, causing the preservative to adhere to the vegetable surface and form a protective film, thereby reducing the vegetables' odor. The respiration rate is then adjusted, and the drive assembly moves the mounting frame 121 and the net box 123 back into the air box 102. The two air supply components are then activated again, and the airflow generated by the two air supply components quickly dries the excess preservative on the surface of the vegetables. Finally, the drive assembly moves the mounting frame 121 and the net box 123 onto the mounting platform 101. The operator then removes the vegetables from the net box 123 and places them into the cold storage. This method can quickly remove field heat and preservatives from freshly harvested vegetables, shortening the time from harvesting to entering the cold storage, thereby improving the efficiency of vegetable preservation and storage.

[0029] Furthermore, the fixing frame 117 is fixedly connected to one end of the mounting frame 121, the drive motor 118 is fixedly connected to the fixing frame 117, the drive shaft 119 is fixedly connected to the output end of the drive motor 118 and passes through the fixing frame 117, the drive gear 120 is fixedly connected to the drive shaft 119 and is located inside the fixing frame 117, and the drive gear 120 is meshed with the gear plate 116.

[0030] In this embodiment, when the mounting frame 121 and the net cage 123 are moved, the drive motor 118 is started. The drive motor 118 drives the drive shaft 119 and the drive gear 120 to rotate. The drive gear 120 meshes with the toothed plate 116 and drives the mounting frame 121 to move. The four sliders 131 slide on the two slide rails 132 respectively, which limit and guide the movement of the mounting frame 121.

[0031] Furthermore, the mounting cylinder 104 is fixedly connected to one end of the air box 102 and communicates with it; the support frame 105 is fixedly connected to the mounting cylinder 104 and is located inside the mounting cylinder 104; the rotary motor 107 is fixedly connected to the support frame 105; the rotating shaft 108 is fixedly connected to the output end of the rotary motor 107 and extends into the air box 102; and a plurality of fan blades 109 are fixedly connected to the end of the rotating shaft 108 away from the rotary motor 107 and are distributed in a circular array.

[0032] In this embodiment, when cold air is supplied to the bellows 102, two rotary motors 107 are activated. The rotary motors 107 drive the rotary shaft 108 and multiple fan blades 109 to rotate. The multiple fan blades 109 guide the outside cold air into the mounting cylinder 104. The cold air enters the bellows 102. The arrangement of the two ventilation slots 106 can increase the air intake of the mounting cylinder 104, ensuring that there is enough airflow into the bellows 102, thus shortening the time for vegetables to remove field heat and dry out excess preservatives.

[0033] Furthermore, the main air guide plate 113 is fixedly connected to the air box 102 and located inside the air box 102, and the two auxiliary air guide plates 114 are fixedly connected to the box body and located on both sides of the main air guide plate 113 respectively.

[0034] In this embodiment, the secondary air guide plate 114 directs a portion of the airflow entering the mounting cylinder 104 to the vegetables on one side of the net box 123, while another portion of the airflow passes through the multiple channels 115 of the secondary air guide plate 114. The airflow through the multiple channels 115 is then directed to the vegetables located in the middle of the net box 123 by the primary air guide plate 113. Through the guiding effect of the two secondary air guide plates 114 and the primary air guide plate 113, the airflow entering the net box 123 is more evenly distributed to the vegetables, thereby improving the efficiency of removing field heat and drying excess preservatives from the vegetables.

[0035] Furthermore, the conical air guide shroud 103 is fixedly connected to the air box 102 and is located below the air box 102.

[0036] In this embodiment, the conical air guide shroud 103 can guide the airflow entering the air box 102 out of the air box 102 to ensure stable air pressure inside the air box 102, thereby improving the efficiency of removing field heat and drying excess preservatives from vegetables.

[0037] Furthermore, the water pump 125 is fixedly connected to the spray box 133, the annular water pipe 126 is fixedly connected to the output end of the water pump 125 and is in communication with it, and the annular water pipe 126 extends into the spray box 133, and a plurality of spray heads 127 are fixedly connected to the annular water pipe 126 and are in communication with it, and the plurality of spray heads 127 are located above the net box 123.

[0038] In this embodiment, when spraying preservative on the vegetables in the net cage 123, the water pump 125 is started, and the water pump 125 delivers preservative to the annular water pipe 126. When the preservative passes through the multiple spray nozzles 127, it is atomized by the multiple spray nozzles 127 and sprayed onto the vegetables. This can greatly reduce the amount of preservative used. Combined with molecular dispersion, it can ensure that the atomized preservative covers the vegetables and is evenly attached to the surface of the vegetables, which can extend the freshness time of the vegetables.

[0039] Furthermore, the flow guide 128 is fixedly connected to the lower part of the spray box 133, the water outlet pipe 129 is fixedly connected to the flow guide 128 and is in communication with it, and the valve 130 is disposed on the water outlet pipe 129.

[0040] In this embodiment, the atomized preservative in the spray box 133 slowly sinks and gradually adheres to the guide shroud 128, flowing down through the outlet pipe 129. When the preservative is sprayed on the vegetables, the valve 130 is closed, keeping the spray box 133 in a relatively sealed state. After the preservative spraying is completed, the valve 130 is opened, and the operator collects the excess preservative flowing out of the outlet pipe 129 for recycling.

[0041] Furthermore, the four partitions 124 are fixedly connected to the cage 123, dividing the internal space of the cage 123.

[0042] In this embodiment, the arrangement of the four dividers 124 can separate the vegetables into several parts, creating gaps between the vegetables so that airflow or atomized preservatives can come into better contact with the vegetables through these gaps, thereby improving the efficiency of removing field heat and drying out excess preservatives.

[0043] Furthermore, the external threaded cylinder 110 is fixedly connected to the end of the mounting cylinder 104 away from the air box 102, the internal threaded cylinder 111 is fixedly connected to the filter plate 112, the external threaded cylinder 110 is threadedly connected to the internal threaded cylinder 111 and is located inside the internal threaded cylinder 111.

[0044] In this embodiment, the filter plate 112 can filter out dust and impurities in the air, preventing impurities from entering the air box 102 and improving the quality of vegetables. At the same time, the filter plate 112 can be disassembled and cleaned periodically by means of the external threaded cylinder 110 and the internal threaded cylinder 111.

[0045] When using this invention to preserve the freshness of vegetables, freshly harvested vegetables are neatly placed in the net box 123. The drive motor 118 is started, which moves the mounting frame 121 and the net box 123 into the bellows 102 until the net box 123 is inside the bellows 102. At this time, the two rotary motors 107 are started, which drive multiple fan blades 109 to rotate and deliver cold air into the bellows 102. The cold air flows rapidly among the vegetables and quickly removes their heat, thus eliminating field heat. Then, the drive motor 118 is started again, which moves the net box 123 and the mounting frame 121 into the spray box 133 until the net box 123 is inside the spray box 133. After that, the drive motor 118 is turned off, and the water pump is started. 125. Multiple spray nozzles 127 atomize the preservative, and the water mist containing the preservative permeates the spray box 133, causing the preservative to adhere to the surface of the vegetables and form a preservative film, thereby reducing the respiration rate of the vegetables. Then, the drive motor 118 moves the mounting frame 121 and the net box 123 into the air box 102 again, and the two rotary motors 107 are started again. The airflow generated by the rotation of multiple fan blades 109 quickly dries the excess preservative on the surface of the vegetables. Finally, the drive motor 118 moves the mounting frame 121 and the net box 123 to the mounting platform 101. The operator takes out the vegetables from the net box 123 and puts them into the cold storage. In this way, the field heat of freshly harvested vegetables can be quickly removed and preservatives can be sprayed, shortening the time from harvesting to entering the cold storage, thereby improving the efficiency of vegetable preservation and freshness storage.

[0046] The second embodiment is based on the first embodiment; please refer to [reference needed]. Figure 7 , Figure 7 This is a flowchart of the steps of a method for preserving and storing vegetables for cultivation according to the present invention.

The cold air flows quickly among the vegetables and quickly removes the heat from the vegetables, thereby eliminating the field heat of the vegetables. S2: Spraying preservative; At this time, the drive motor 118 is started again, and the drive motor 118 drives the net box 123 and the mounting frame 121 to move towards the spray box 133.

The water mist containing the preservative diffuses in the spray box 133, so that the preservative adheres to the surface of the vegetables and forms a preservative film, thereby reducing the respiration rate of the vegetables. S3: Dry out excess preservative; then the drive motor 118 moves the mounting frame 121 and the net box 123 into the wind box 102 again, and the two rotary motors 107 are started again. The airflow formed by the rotation of the multiple fan blades 109 quickly dries the excess preservative on the surface of the vegetables. S4: Transfer vegetables; Finally, the drive motor 118 moves the mounting frame 121 and the net box 123 to the mounting platform 101, and the operator takes out the vegetables from the net box 123 and puts them into the cold storage.

[0048] When using the vegetable cultivation preservation and fresh storage method of this embodiment, freshly harvested vegetables are neatly placed in the net box 123.

After the container 123 is moved into the spray box 133, the drive motor 118 is turned off, and the water pump 125 is started. Multiple spray nozzles 127 atomize the preservative, and the water mist containing the preservative permeates the spray box 133, causing the preservative to adhere to the surface of the vegetables and form a preservative film, thereby reducing the respiration rate of the vegetables. Then, the drive motor 118 moves the mounting frame 121 and the net box 123 into the air box 102 again, and the two rotary motors 107 are started again.

10. A method for preserving and storing vegetables during cultivation, comprising using the equipment described in claim 9 to preserve vegetables, characterized in that, S1: Vegetables remove field heat; The freshly picked vegetables are neatly placed in the net box. The drive motor is started, and the drive motor drives the mounting frame and the net box to move into the wind box. When the net box moves into the wind box, the two rotary motors are started. The two rotary motors drive multiple fan blades to rotate and deliver cold air into the wind box. The cold air flows quickly among the vegetables and quickly removes the heat from the vegetables, thereby eliminating the field heat of the vegetables. S2: Spray preservative; At this time, the drive motor is restarted, and the drive motor drives the net box and the mounting frame to move towards the spray box. After the net box moves into the spray box, the drive motor is turned off and the water pump is started. Multiple spray heads atomize the preservative. The water mist containing the preservative diffuses in the spray box, so that the preservative adheres to the surface of the vegetables and forms a preservative film, thereby reducing the respiration rate of the vegetables. S3: Air-dry excess preservatives; Then, the drive motor moves the mounting frame and the net box into the air box again, and the two rotary motors are started again. The airflow generated by the rotation of the multiple fan blades quickly dries the excess preservative on the surface of the vegetables. S4: Transfer vegetables; Finally, the drive motor moves the mounting frame and the net box to the mounting platform, and the operator takes out the vegetables from the net box and puts them into the cold storage.
