Description

Technical Field

[0001] This utility model relates to the field of spray preservation equipment technology, specifically a spray preservation device for fruit and vegetable preservation warehouses. Background Technology

[0002] As a core facility for extending the shelf life and ensuring the quality of fruits and vegetables, the precise control of their internal temperature and humidity environment directly determines the preservation effect. Among them, spray preservation technology has become one of the key technologies widely used in fruit and vegetable cold storage because it can quickly replenish air humidity and lower the ambient temperature through atomized water molecules. At the same time, it can be used with preservatives to achieve functions such as antibacterial and antioxidant effects.

[0003] According to the search, Chinese patent document CN215775255U discloses a spray preservation device for fruit and vegetable storage. The nozzle position is adjusted by moving the mounting base and fixed base, and movement is restricted by a fixed handle. An external air compressor unit provides power and water to the nozzle for spraying. Resin rollers reduce friction when trays are slid in and out, improving workability and allowing for straight insertion and removal. Multiple trays can be placed and any one can be removed simultaneously. Once a tray has slid into position, it is stopped by a stop post. Water collected from the continuous spraying of water mist falls into a collection tank through a drain trough.

[0004] However, the above-mentioned spray preservation device has the problem of insufficient spray uniformity in actual use. After manual adjustment, the position of the nozzle is fixed and can only spray in one direction. This causes some fruits and vegetables to absorb too much water mist and form water accumulation on the surface, making them prone to mold. Other parts cannot fully absorb water mist and suffer from insufficient moisture. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a spray preservation device for fruit and vegetable preservation warehouses. It features a swing structure that expands the spray range, allowing all fruits and vegetables to absorb water mist and retain moisture. It also avoids the problem of water accumulation on the surface of fruits and vegetables caused by repeated spraying in the same area, thus solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a spray preservation device for fruit and vegetable preservation, comprising a fruit and vegetable storage rack and a water tank. An ultrasonic atomizer is installed inside the water tank, and a cover plate is bolted to the top surface of the water tank. An axial flow fan is bolted to the top surface of the cover plate. A fan hood is connected to the air outlet of the axial flow fan, and a conveying pipe is inserted into the top of the fan hood. A branch pipe is fixedly connected to the outer wall of the conveying pipe. A rotary joint is fixedly connected to one end of the branch pipe, and a spray pipe is rotatably connected to one end of the rotary joint. A sector gear is fixedly connected to the outer circumference of the spray pipe, and a rack is meshed with the sector gear. A guide rail is fixedly connected to the back of the rack, and a sliding sleeve is slidably connected to the outer surface of the guide rail. A connecting plate is rotatably connected to the outer surface of the rack via a pin. An end shaft is rotatably connected to one end of the connecting plate, and a turntable is rotatably connected to one end of the end shaft. The output shaft of a reduction motor is connected to the center of the bottom surface of the turntable.

[0009] Preferably, the fruit and vegetable storage rack includes four sets of support rods, with fruit and vegetable storage plates bolted to the side walls of the support rods, and a horizontal plate welded to the other side wall of the support rods.

[0022] 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.

[0023] Please see Figures 1-4A spray preservation device for fruit and vegetable preservation includes a fruit and vegetable storage rack 1 and a water tank 2. An ultrasonic atomizer 3 is installed inside the water tank 2, and a cover plate 4 is bolted to the top surface of the water tank 2. An axial flow fan 5 is bolted to the top surface of the cover plate 4, and a fan hood 6 is connected to the air outlet of the axial flow fan 5. A conveying pipe 7 is inserted into the top of the fan hood 6, and a branch pipe 8 is fixedly connected to the outer wall of the conveying pipe 7. A rotary joint 9 is fixedly connected to one end of the branch pipe 8, and one end of the rotary joint 9 can rotate. A spray pipe 10 is connected, and a sector gear 11 is fixedly connected to the outer circumference of the spray pipe 10. The sector gear 11 is meshed with a rack 12. A guide rail 13 is fixedly connected to the back of the rack 12. A sliding sleeve 14 is slidably connected to the outer surface of the guide rail 13. A connecting plate 15 is rotatably connected to the outer surface of the rack 12 via a pin. An end shaft 16 is rotatably connected to one end of the connecting plate 15. A turntable 17 is rotatably connected to one end of the end shaft 16. The output shaft of a reduction motor 18 is connected to the center of the bottom surface of the turntable 17.

[0024] Specifically, the fruit and vegetable storage rack 1 includes four sets of support rods 101, with fruit and vegetable storage plates 102 bolted to the side walls of the support rods 101, and a horizontal plate 103 welded to the other side wall of the support rods 101.

[0025] Specifically, there are several fruit and vegetable storage boards 102, and each of the fruit and vegetable storage boards 102 has a drainage hole through its bottom surface. The number of horizontal boards 103 is the same as that of the fruit and vegetable storage boards 102, and a spray pipe 10 is rotatably connected inside the horizontal board 103.

[0026] The advantages are that by setting four sets of support rods 101, several fruit and vegetable storage racks 1 can be supported. Fruits and vegetables can be placed on the upper surface of the fruit and vegetable storage racks 1. The multiple drainage holes on the bottom surface of the fruit and vegetable storage board 102 can help to drain excess water mist or water seeping from the fruits and vegetables themselves that may accumulate on the surface of the fruit and vegetable storage board 102 during the spraying process. This prevents water from remaining on the surface of the storage board or the bottom of the fruits and vegetables for a long time, and prevents the fruits and vegetables from becoming moldy or rotting due to continuous contact with water at the bottom.

[0027] Specifically, multiple spray nozzles are provided on the outer periphery of the spray pipe 10, a controller 19 is installed on the front of the water tank 2, and a water level sensor is installed inside the water tank 2.

[0028] The advantage is that the controller 19 can activate the ultrasonic atomizer 3, which causes a large amount of water mist to be generated inside the water tank 2. At the same time, the axial flow fan 5 can send the water mist generated in the water tank 2 into the fan hood 6. Then the water mist goes into the delivery pipe 7, and then through the branch pipe 8 and the rotary joint 9, the water mist enters into each spray pipe 10. Finally, it is discharged from the spray nozzle on the outer circumference of the spray pipe 10. In this way, the fruits and vegetables placed on the fruit and vegetable storage plate 102 can be sprayed to keep them moist.

[0029] Specifically, the turntable 17 is eccentrically connected to the end shaft 16, and a side plate 20 is fixedly connected to the side wall of one of the support rods 101. A geared motor 18 is bolted to the outer surface of the side plate 20.

[0030] Specifically, the sliding sleeve 14 is bolted to the outer surface of the horizontal plate 103, and the top surface of the water tank 2 is fixedly connected to the water filling hopper 21.

[0031] The advantage is that during the spraying and moisturizing process of fruits and vegetables, the turntable 17 is rotated by starting the reduction motor 18. Since the turntable 17 and the end shaft 16 are eccentrically connected, the rotation of the turntable 17 will pull the connecting plate 15 to reciprocate through the end shaft 16. The other end of the connecting plate 15 is rotatably connected to the rack 12 through a pin, which in turn drives the rack 12 to slide linearly back and forth along the matching structure of the guide rail 13 and the sliding sleeve 14 on its back. The rack 12 meshes with the sector gear 11 fixed on the outer periphery of the spray pipe 10. The reciprocating sliding of the rack 12 will be converted into the reciprocating rotation of the sector gear 11, and one end of the spray pipe 10 will rotate through the rotation. The connector 9 is rotatably connected to the branch pipe 8, and the other end is rotated into the horizontal plate 103. Finally, driven by the sector gear 11, the spray pipe 10 realizes reciprocating oscillation spraying. This can effectively expand the spray range and ensure that fruits and vegetables in different positions on the fruit and vegetable storage plate 102 can be evenly contacted with water mist. This avoids the problem of insufficient moisture in some fruits and vegetables caused by spraying in a fixed direction, and also prevents water accumulation and mold growth on the surface of fruits and vegetables caused by repeated spraying in the same area. At the same time, the drainage holes on the bottom of the fruit and vegetable storage plate 102 can drain excess water in time, further ensuring the freshness of fruits and vegetables and improving the practicality and freshness reliability of the device.

[0032] In use, firstly, add sufficient clean water to the water tank 2 through the water filling hopper 21. The water level sensor inside the water tank 2 can monitor the water level to ensure sufficient water supply. Then, evenly place the fruits and vegetables to be preserved on several fruit and vegetable storage plates 102. Next, the controller 19 starts the ultrasonic atomizer 3 and axial flow fan 5 inside the water tank 2. The ultrasonic atomizer 3 converts the clean water in the water tank 2 into a large amount of water mist, while the axial flow fan 5 sends the water mist generated in the water tank 2 into the fan hood 6 connected to its outlet. Then, the water mist enters through the delivery pipe 7 inserted at the top of the fan hood 6, and then through several branch pipes 8, and is delivered to the spray pipe 10 via the rotary joint 9. Finally, it is initially sprayed out from multiple spray nozzles on the outer periphery of the spray pipe 10. Simultaneously, the reduction motor 18 is started, and its output shaft drives the turntable 17 to rotate. Because the turntable 17 is eccentrically connected to the end shaft 16, the rotation of the turntable 17... The connecting plate 15 is pulled by the shaft 16 to reciprocate. The other end of the connecting plate 15 is rotatably connected to the rack 12 through a pin, which in turn drives the rack 12 to slide linearly back and forth along the cooperation structure between the guide rail 13 and the sliding sleeve 14 on its back. The rack 12 meshes with the sector gear 11 fixed on the outer periphery of the spray pipe 10. The reciprocating sliding of the rack 12 is converted into the reciprocating rotation of the sector gear 11. One end of the spray pipe 10 is rotatably connected to the branch pipe 8 through the rotary joint 9, and the other end is rotatably connected to the inside of the horizontal plate 103. Finally, under the drive of the sector gear 11, the spray pipe 10 is reciprocated to spray, so as to evenly moisturize the fruits and vegetables on the fruit and vegetable storage plate 102. During the spraying process, the drainage holes through the bottom surface of the fruit and vegetable storage plate 102 can drain the excess water mist accumulated on the plate or the water seeping out of the fruits and vegetables in time, so as to avoid water accumulation and mold at the bottom of the fruits and vegetables, thus completing the entire fruit and vegetable spraying preservation operation process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
