[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, a filter plate is fixedly connected to the lower end of the planting box, and the filter plate infiltrates the saline-alkali soil water into the connecting frame. At night, the heating plate in the middle of the bottom end of the connecting frame is powered on, and the heating plate heats the liquid infiltrated in the saline-alkali soil, so that the infiltrated liquid inside the heating plate is continuously heated and volatilized, so that the liquid water forms water vapor and floats upward;

[0018] Most of the water vapor floats upward to the inner surface of the outer condensation shell. At night, the temperature of the outer condensation shell and the condensation plate drops to between degrees Celsius and degrees Celsius. The water vapor inside the outer tank is continuously condensed into liquid and attached to the inner surface of the outer condensation shell. A condensation groove is provided between the two condensation plates. The condensation groove guides the liquid downward, so that the fresh water that forms water vapor flows back to the fresh water storage tank again. This setting makes the water vaporize first and then liquefy using the ambient temperature. This process minimizes the loss of water and avoids the escape of a large amount of water in the form of water vapor.

[0019] 2. The lateral movement of the movable plate in the present invention pushes the powdered fertilizer inside it laterally toward the inclined surface close to the storage shell. During the lateral movement of the entire movable plate, the first discharge port at the lower end of the movable plate moves to the upper side of the second discharge port, and the powdered fertilizer inside the movable plate gradually drops downward from the first discharge port and the second discharge port to the interior of the fresh water storage tank. After the powdered fertilizer inside the movable plate falls for seconds, the gear drives the ring gear to rotate clockwise, so that the arc-shaped push plate therein disengages from the plug-in hole to the outside, and the squeezing of the movable plate by the arc-shaped push plate ends. The contraction elastic force of the two springs on one side of the movable plate drives the movable plate to move laterally to its original position, thereby staggering the first discharge port and the second discharge port, and the powdered fertilizer inside the storage shell stops falling. The setting of the overall discharge mechanism controls the time of discharging the powdered fertilizer, and then controls the amount of powdered fertilizer discharged.

[0031] Generally, saline-alkali lands are located in deserts, where there is a large temperature difference between day and night. At night, the temperature in the environment gradually drops to between 7 degrees Celsius and 12 degrees Celsius. This temperature difference causes water vapor to condense into liquid.

[0032] The unloading mechanism 5 includes a clamping block 501 inserted into the upper end of the second connecting plate 10, the upper end of the clamping block 501 is fixedly connected to a storage shell 502, the upper end of the storage shell 502 is clamped with an upper end cover 505, the upper end of the storage shell 502 is horizontally penetrated with a waist hole 509, the waist hole 509 is horizontally movably provided with a movable plate 507, one side of the lower end of the movable plate 507 is fixedly connected to a movable plate 503, one end of the movable plate 503 is connected to a spring 504, and the two springs 504 are connected to the inner wall of the storage shell 502;

[0034] A cavity is formed between the storage shell 502 and the movable plate 503, and the cavity is filled with powdered solid fertilizer. The powdered solid fertilizer fills three quarters of the space in the cavity. This filling method makes the cavity formed between the storage shell 502 and the movable plate 503 have a buffer.

[0035] The water evaporation mechanism 6 includes a planting box 601 fixedly connected between two second connecting plates 10, a filter plate 602 is provided in the middle of the lower end of the planting box 601, first connecting plates 605 are fixedly connected to both sides of the lower end of the planting box 601, and a connecting frame 603 is fixedly connected to the lower ends of the two first connecting plates 605. A heating plate 604 is provided in the middle of the connecting frame 603. When fresh water is sprayed from the upper end of the planting box 601 into the inside of the planting box 601, the fresh water can flush the saline-alkali components in the saline-alkali soil, and the fresh water carries the saline-alkali components to the connecting frame 603, and the heating plate 604 in the middle of the connecting frame 603 heats the brine inside. The heating causes the liquid water to form water vapor and float upward, and finally most of the saline-alkali components remain in the connecting frame 603.

[0036] The planting box 601 is filled with saline-alkali soil, and a spray pipe is provided on one side of the fresh water storage tank 1 . A pressure pump is connected to the spray pipe by bolts, and the water inlet of the spray pipe extends to the bottom of the fresh water storage tank 1 .

[0037] When in use, the whole device is applied in a saline-alkali land environment, and the user uses a filling tool to fill the inside of the planting box 601 with saline-alkali soil, wherein the fresh water storage tank 1 is connected to an external water pipe, and the water pump on the water pipe pumps fresh water from the water source into the fresh water storage tank 1, wherein the fresh water in the fresh water storage tank 1 does not exceed the bottom end surface of the heating plate 604, and then the pressure pump on the spray pipe inside the fresh water storage tank 1 works, so that the fresh water in the fresh water storage tank 1 is extracted and sprayed onto the saline-alkali soil inside the planting box 601;

[0038] The lower end of the planting box 601 is fixedly connected with a filter plate 602, and the filter plate 602 infiltrates the saline-alkali soil water into the connecting frame 603. At night, the heating plate 604 in the middle of the bottom end of the connecting frame 603 is powered on, and the heating plate 604 heats the liquid infiltrated in the saline-alkali soil, so that the infiltrated liquid inside the heating plate 604 is continuously heated and volatilized, so that the liquid water forms water vapor and floats upward;

[0039] Most of the water vapor floats upward to the inner surface of the outer condensation shell 201. At night, the temperature of the outer condensation shell 201 and the condensation plate 203 drops to between 7 degrees Celsius and 15 degrees Celsius. The water vapor inside the outer tank 202 is continuously condensed into liquid and attached to the inner surface of the outer condensation shell 201. A condensation tank 207 is provided between the two condensation plates 203. The condensation tank 207 guides the liquid downward, thereby allowing the fresh water that forms water vapor to flow back to the fresh water storage tank 1 again.

[0040] Then the servo motor 7 is powered on, the rotating shaft at the upper end of the servo motor 7 drives the gear 8 to rotate, the gear 8 drives the ring gear 9 to rotate, the ring gear 9 drives the upper end of the overall condensing mechanism 2 to rotate, wherein the arc push plate 204 is located in the middle of the upper side of the water evaporation mechanism 6 close to the servo motor 7, first the overall arc push plate 204 is driven by the condensation plate 203 to rotate 90 degrees counterclockwise, then the arc push plate 204 is rotated and inserted into the plug hole 506 at the bottom end of the storage shell 502, at this time the state of the internal part of the overall unloading mechanism 5 is changed from Figure 6 As shown;

[0041] When the arc-shaped push plate 204 pushes the movable plate 503 laterally inward, the lateral movement of the movable plate 503 pushes the powdered fertilizer inside it laterally toward the inclined surface close to the storage shell 502. During the lateral movement of the entire movable plate 503, the first discharge port 508 at the lower end of the movable plate 503 moves to the upper side of the second discharge port 510, and the powdered fertilizer inside the movable plate 503 gradually falls downward from the first discharge port 508 and the second discharge port 510 to the inside of the fresh water storage tank 1;

[0042] 5 seconds after the powdered fertilizer inside the movable plate 503 falls, the gear 8 drives the ring gear 9 to rotate clockwise, so that the arc-shaped push plate 204 therein disengages from the plug-in hole 506, and the squeezing of the movable plate 503 by the arc-shaped push plate 204 ends. The contraction elastic force of the two springs 504 on one side of the movable plate 503 drives the movable plate 503 to move horizontally to the original position, thereby making the first discharge port 508 and the second discharge port 510 staggered, and the powdered fertilizer inside the storage shell 502 stops falling.

[0043] Finally, the ring gear 9 drives the stirring rod 205 and the stirring blade 206 at the lower end of the arc-shaped push plate 204 to rotate back and forth inside the fresh water storage tank 1, and the angle of the back and forth rotation and swing does not exceed 90 degrees, so that the water and powdered fertilizer inside the fresh water storage tank 1 are stirred and mixed. When the pressure pump runs again, the spray pipe irrigates and fertilizes the plant seedlings planted inside the water evaporation mechanism 6.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
