[0020] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, which provides a refrigerated shelf for selling agricultural and sideline products, including a storage cabinet 100 and a shelf 200 fixedly installed on top of it, with a refrigeration mechanism 300 above the shelf 200. Furthermore, the shelf 200 is a rectangular structure with an open top. A water collection box 201 with several filter holes at the top is fixedly connected to the bottom of the inner wall of the shelf 200. A drain pipe 202 is fixedly connected to one side of the water collection box 201. The end of the drain pipe 202 away from the water collection box 201 extends to the outside of the shelf 200 and is fixedly connected thereto. The preservation mechanism 300 includes a rectangular frame 301 set above the top of the shelf 200. The bottom of the rectangular frame 301 is slidably connected to the top of the shelf 200. A water filter is fixedly connected to the inner wall of the rectangular frame 301. The spray pipes 302 are arranged horizontally, and there are at least three spray pipes 302. Each spray pipe 302 has multiple spray heads 303 that are equidistantly connected to its bottom. Adjacent spray pipes 302 are fixedly connected to each other by a connecting pipe 305. A water supply pipe 306 is fixedly connected to one side of the central spray pipe 302. It should be noted that an electromagnetic valve is provided at the end of the drain pipe 202 to control the flow speed of wastewater discharged from the water collection box 201. The water supply pipe 306 is a telescopic hose to ensure a stable water supply to the inside of the spray pipes 302 when the rectangular frame 301 moves up and down.

[0021] Specifically, the shelf 200 is a rectangular structure with an open top, used to hold agricultural and sideline products for sale. Its internal space facilitates the neat arrangement of fruits, vegetables, and other goods. A water collection box 201 is fixedly connected to the bottom of the inner wall of the shelf 200. The top of the water collection box 201 has several filter holes, which allow excess water or spray condensate generated during the preservation process to flow smoothly into the water collection box 201. A drain pipe 202 is fixedly connected to one side of the water collection box 201, and the end of the drain pipe 202 away from the water collection box 201 extends to the shelf. The outer side of the shelf 200 is fixedly connected to it for draining collected wastewater. An electromagnetic valve is installed at the end of the drain pipe 202 to precisely control the flow rate of wastewater discharged from the collection box 201, enabling timed or on-demand drainage. The preservation mechanism 300 includes a rectangular frame 301 positioned above the top of the shelf 200. The bottom of the rectangular frame 301 is slidably connected to the top of the shelf 200, allowing the rectangular frame 301 to move vertically up and down to accommodate agricultural products of different heights. The spray pattern is adjusted to expand the spray coverage area and adapt to the display needs of different types of fruits and vegetables. At least three horizontally arranged spray pipes 302 are fixedly connected to the inner wall of the rectangular frame 301, arranged in a horizontal parallel pattern to ensure a wider and more uniform spray coverage area. Each spray pipe 302 has multiple equidistantly arranged spray heads 303 fixedly connected to its bottom. The spray heads 303 atomize water and spray it evenly onto the surface of the agricultural products, increasing ambient humidity, preventing fruits and vegetables from wilting due to dehydration, and maintaining their freshness and shine. The adjacent water spray pipes 302 are fixedly connected by a connecting pipe 305 to achieve water flow and ensure balanced water supply. A water supply pipe 306 is fixedly connected to one side of the water spray pipe 302 located in the center. The water supply pipe 306 is a retractable flexible hose, with one end connected to the water supply source and the other end connected to the water spray pipe 302. Due to the retractable design, the water flow can be kept unobstructed even when the rectangular frame 301 slides up and down, and water can be continuously and stably supplied to the water spray pipe 302, avoiding pipe breakage or water supply interruption due to movement.

[0022] Furthermore, when it is necessary to preserve the displayed agricultural products, water enters the central spray pipe 302 through the water supply pipe 306, and flows to the spray pipes 302 on both sides through the connecting pipe 305. Finally, it forms a fine water mist through the spray head 303 and sprays it onto the product surface. Excess water flows into the water collection box 201 through the filter holes at the bottom of the shelf 200, and is then discharged through the drain pipe 202. The electromagnetic valve can automatically open to drain the water, keeping the internal environment clean. The rectangular frame 301 can slide to adjust its height to accommodate agricultural products of different stacking heights, improving spraying efficiency and space utilization. This preservation shelf effectively solves the problems of easy water loss, mixed stacking, and inconvenient management of products in traditional sales shelves through spray humidification, water collection and drainage, and adjustable structure, improving the preservation effect and display aesthetics of agricultural products during the sales process.

[0023] Example 2 In the second embodiment of this utility model, both the front and rear ends of one side of the outer wall of the storage shelf 200 are fixedly connected to vertically arranged electric telescopic rods 304. The tops of the two electric telescopic rods 304 are fixedly connected to one side of the rectangular frame 301. A water tank 308 is fixedly connected to one side of the storage cabinet 100. A water pump 307 is fixedly connected to the top of the water tank 308. The water outlet of the water pump 307 is fixedly connected to the end of the water supply pipe 306 away from the spray pipe 302.

[0024] Furthermore, a water pump 307 is fixedly connected to a water pump pipe 309 at its pumping end. The end of the water pump pipe 309 away from the water pump 307 is fixedly connected to the bottom of the side of the water storage tank 308. A water injection pipe 310 is fixedly connected to the top side of the water storage tank 308. A cabinet door 101 is rotatably connected to the front surface of the storage cabinet 100. A handle 102 and a controller 103 are fixedly connected to the front surface of the cabinet door 101.

[0025] Specifically, the top of the electric telescopic pole 304 is connected to one side of the rectangular frame 301. It can be activated by the controller 103 to adjust the height of the rectangular frame 301, so that the spray head 303 is closer to or further away from the agricultural products. The water storage tank 308 is located on one side of the storage cabinet 100, and the top is equipped with a water injection pipe 310 to replenish the water source. The water pump 307 is installed on the top of the water storage tank 308. It draws clean water from the water storage tank 308 through the water pumping pipe 309 and delivers it to the central spray pipe 302 through the water supply pipe 306, and then distributes it to other spray pipes 302 to ensure that all spray pipes 302 can receive sufficient water.

[0026] Furthermore, the storage cabinet 100 can store agricultural and sideline products awaiting sale. To control the height of the entire preservation mechanism 300 relative to the top of the shelf 200, the operator activates the electric telescopic rod 304 via the controller 103. The activated electric telescopic rod 304 drives the rectangular frame 301, the water spray pipe 302, and the spray head 303 downwards, gradually approaching the top of the shelf 200. When the spray head 303 approaches the top of the shelf 200, it can spray water onto the agricultural and sideline products stored inside the shelf 200. When continuous water supply to the water spray pipe 302 is needed, the operator activates the controller 103. A water pump 307 draws clean water from the water storage tank 308 through a water pumping pipe 309. The clean water is then transported along the water pumping pipe 309 and the water pump 307 to the water delivery pipe 306. The clean water entering the water delivery pipe 306 is first injected into the central spray pipe 302. The clean water entering the spray pipe 302 then enters other spray pipes 302 through a connecting pipe 305, ensuring that all spray pipes 302 are filled with clean water. The clean water injected into the spray pipes 302 is then sprayed onto the surface of the agricultural and sideline products inside the shelf 200 through multiple spray nozzles 303, thereby ensuring the freshness of the agricultural and sideline products when they are sold.

[0027] Example 3 In the third embodiment of this utility model, a central plate 203 is fixedly connected to the center of the top of the water collection box 201. The front and rear ends of the central plate 203 are fixedly connected to the front and rear sides of the inner wall of the water collection box 201, respectively. Movable baffles 204 are provided on both the left and right sides of the central plate 203. The bottom of the two movable baffles 204 are slidably connected to the top of the water collection box 201.

[0028] Furthermore, a rectangular shell 205 is fixedly connected to the top rear side of the storage shelf 200 and is arranged parallel to it. A horizontal moving groove 206 is opened at the center of the top of the rectangular shell 205. A horizontally arranged bidirectional threaded rod 207 is rotatably connected inside the rectangular shell 205. Threaded sleeves 208 are threadedly connected to both the left and right sides of the surface of the bidirectional threaded rod 207. A horizontally arranged guide rod 210 is fixedly connected between the left and right sides of the inner wall of the threaded sleeve 208. The guide rod 210 is slidably connected to the two threaded sleeves 208.

[0029] Furthermore, each of the two threaded sleeves 208 is fixedly connected to a connecting rod 209. The ends of the two connecting rods 209 away from the threaded sleeves 208 extend to the top of the rectangular shell 205 and are fixedly connected to the rear top of the two movable baffles 204. The surfaces of the two connecting rods 209 are slidably connected to the inner wall of the movable groove 206. One end of the bidirectional threaded rod 207 is rotatably connected to one side of the inner wall of the rectangular shell 205.

[0030] Furthermore, the other end of the bidirectional threaded rod 207 extends to one side of the rectangular shell 205 and is rotatably connected thereto. A power motor 211 is fixedly connected to one side of the outer wall of the rectangular shell 205. The output shaft of the power motor 211 is fixedly connected to one end of the bidirectional threaded rod 207. A protective cover 212 is provided outside the power motor 211. One side of the protective cover 212 is fixedly connected to one side of the rectangular shell 205.

[0031] Specifically, the front and rear ends of the center plate 203 are fixedly connected to the front and rear sides of the inner wall of the water collection box 201 to ensure structural stability. The bottom of the movable baffle 204 is slidably connected to the top of the water collection box 201, allowing it to move horizontally to adjust the spacing. A rectangular shell 205 is fixedly connected to the top of the rear side of the shelf 200 and is arranged parallel to it. A horizontal moving groove 206 is opened at the center of the top of the rectangular shell 205, and a bidirectional threaded rod 207 is rotatably connected inside to drive the movement of the movable baffle 204. Threaded sleeves 208 are threadedly connected to both the left and right sides of the surface of the bidirectional threaded rod 207. A guide rod 210 is fixedly connected between the left and right sides of the wall. The guide rod 210 restricts the threaded sleeve 208 to slide only along the surface of the bidirectional threaded rod 207 without rotating. A connecting rod 209 is fixedly connected to the top of the threaded sleeve 208. The connecting rod 209 passes through the moving groove 206 and is fixedly connected to the rear top of the movable baffle 204. The power motor 211 is fixed to one side of the outer wall of the rectangular shell 205. Its output shaft is connected to one end of the bidirectional threaded rod 207. When the power motor 211 is started, the bidirectional threaded rod 207 rotates, driving the threaded sleeve 208 and the movable baffle 204 to move synchronously, thereby realizing the adjustment of the distance between the movable baffles 204.

[0032] Furthermore, since different agricultural and sideline products require different amounts of space, it is necessary to adjust the distance between the movable baffle 204 and the center plate 203. The operator starts the power motor 211 through the controller 103. After starting, the power motor 211 drives the bidirectional threaded rod 207 to rotate inside the rectangular shell 205. When the bidirectional threaded rod 207 rotates with the power motor 211, the threaded sleeves 208 fitted on the left and right sides of the surface of the bidirectional threaded rod 207 can rotate synchronously with the bidirectional threaded rod 207. Due to the limiting effect of the guide rod 210, the two threaded sleeves 208 can move closer or further away from each other along the left and right sides of the surface of the bidirectional threaded rod 207. During the process of the two threaded sleeves 208 moving closer or further away from each other, the connecting rod 209 drives the two movable baffles 204 to move closer or further away from the center plate 203, so as to adjust the distance between the movable baffles 204 and the center plate 203 for the sale of different agricultural and sideline products.

[0033] Working principle: The operator opens cabinet door 101 and neatly arranges the agricultural and sideline products for sale in the shelf 200. Based on the types of agricultural and sideline products currently displayed, the operator inputs adjustment commands into controller 103. Controller 103 starts the power motor 211, and the output shaft of the power motor 211 drives the bidirectional threaded rod 207 to rotate within the rectangular shell 205. Because the thread directions on the left and right sides of the bidirectional threaded rod 207 are opposite, the two threaded sleeves 208 will move synchronously but in opposite directions along the surface of the threaded rod during rotation (i.e., one to the left and one to the right). The guide rod 210 is fixed between the two threaded sleeves 208, restricting their rotational freedom and ensuring the threaded sleeves... 208 can only slide linearly along the axial direction. The movement of the threaded sleeve 208 is transmitted to the movable baffle 204 through the connecting rod 209. The connecting rod 209 passes through the moving groove 206 at the top of the rectangular shell 205, driving the two movable baffles 204 to slide along the top of the water collection box 201. When it is necessary to expand the middle area, the two movable baffles 204 move away from the center plate 203. When it is necessary to reduce the space or separate multiple categories, the movable baffles 204 move closer to the center plate 203. After the adjustment is completed, the power motor 211 stops, and the movable baffles 204 are fixed in the new position, realizing flexible partitioning of the internal space of the storage shelf 200 and avoiding product mixing. Based on the stacking height of the agricultural products, the operator activates two electric telescopic rods 304 via controller 103. The electric telescopic rods 304 extend or retract, causing the rectangular frame 301 connected to their top to slide vertically up and down. The rectangular frame 301 then raises and lowers the water spray pipe 302 and spray head 303 fixed below it. Adjustment stops when the spray head 303 approaches the product surface (but does not touch it), ensuring even spray coverage without causing water pressure damage. Because the water supply pipe 306 is a flexible, extendable hose, even with the rectangular frame 301 moving up and down, the water path remains unobstructed, ensuring a continuous water supply. The operator starts the water pump 307 through the controller 103. The water pump 307 draws clean water from the bottom of the water storage tank 308 through the water pipe 309. After being pressurized by the water pump 307, the clean water is delivered to the central spray pipe 302 through the water delivery pipe 306. The water in the central spray pipe 302 flows into other spray pipes 302 on the left and right sides through the connecting pipe 305, realizing simultaneous water supply from multiple pipes. After the water reaches the spray head 303, it is atomized into a fine mist and sprayed evenly on the surface of agricultural products, increasing the ambient humidity, preventing fruits and vegetables from losing water and wilting, reducing the surface temperature, slowing down respiration, and extending the shelf life. Excess water or condensate drips from the product surface during the spraying process, passes through the filter holes at the bottom of the shelf 200, and enters the water collection box 201. When the water level in the water collection box 201 reaches the set value, the controller 103 automatically opens the solenoid valve at the end of the drain pipe 202, and the wastewater is discharged outside the shelf through the drain pipe 202.

[0034] In summary: the bidirectional threaded rod 207 driven by the power motor 211 enables automatic adjustment of the spacing of the movable baffle 204, adapting to different types and sizes of agricultural and sideline products and preventing mixed piling. The electric telescopic rod 304 drives the spraying mechanism to rise and fall, ensuring that the spray head 303 is always at the optimal spraying height. The water pump 307 and spray head 303 achieve automatic humidification and preservation, improving product freshness. The water collection box 201, drain pipe 202, and solenoid valve enable automatic collection and discharge of wastewater, maintaining cleanliness and hygiene.
