[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0021] refer to Figures 1 to 12 A greening planting box with water storage and drainage functions for agriculture and forestry provided in an embodiment of the present invention comprises a shell 1, a support rod 2 is fixedly connected to the inner bottom surface of the shell 1, a planting bin 3 is fixedly connected to the support rod 2, and also comprises a water source storage mechanism, the water source storage mechanism comprises a water control bin 4 which is sleeved on the outer side of the planting bin 3 and can slide up and down inside the shell 1, a plurality of installation grooves are provided on the outer side of the shell 1, a filter component for filtering impurities in the water is provided on one side of the installation groove close to the planting bin 3, a water storage component for storing water and conveying the stored water to the planting bin 3 is provided on the other side of the installation groove, and a water source discharge mechanism is provided, the water source discharge mechanism is arranged in the water control bin 4, and is used to discharge excess water inside the shell 1 after the water storage component is full of water.

[0022] When in use, the planting chamber 3 and the water control chamber 4 are filled with soil respectively, and the plants are planted in the planting chamber 3. In the initial state, the filter assembly is closed on the outside of the water control chamber 4.

[0023] When the amount of water entering is small: at this time, the water source above the planting chamber 3 and the water control chamber 4 will directly penetrate into the soil, thereby first satisfying the watering of the plants, and in the process of water source infiltrating into the water control chamber 4, the water control chamber 4 will gradually slide down, thereby gradually exposing the filter component, but because the amount of water is small and will directly penetrate into the soil, no water source will enter the water storage component.

[0024] When the amount of water entering is large: the water control chamber 4 will gradually slide down to expose the filter component. After the water in the soil in the water control chamber 4 reaches saturation, the filter component is completely exposed, and at this time there is a height difference between the water control chamber 4 and the planting chamber 3. As the water source continues to enter, water will accumulate above the soil in the water control chamber 4, and the water source accumulated above the planting chamber 3 will flow into the water control chamber 4 due to the existence of the height difference. The accumulated water source will be filtered by the filter component and enter the water storage component. The filter component can filter out impurities and soil in the water source. If water source still enters after the water storage component is full, the water storage component will discharge the excess water source into the water source discharge mechanism for discharge.

[0025] When there is sufficient water inside the water storage component, it will continue to provide water for the plants in the planting chamber 3, and the water control chamber 4 will gradually return to the top as the water inside it is lost, thereby closing the filter component again.

[0026] Through the above-mentioned arrangement, the sliding movement of the water control chamber 4 after water infiltration can be utilized to store excess water while ensuring that the plants are effectively watered, thereby effectively improving the planting effect of the plants and reducing the planting cost. By setting up a filtering component, soil loss is effectively avoided. At the same time, by setting up a water source discharge mechanism, excess water can be quickly discharged after storing sufficient water source, thereby preventing water source accumulation and causing plant death, thereby effectively improving the use effect of the planting box.

[0027] Furthermore, the water storage component includes a U-shaped water storage tank 5, one end of which is fixedly connected to the side of the installation groove away from the filter component, the other end of the U-shaped water storage tank 5 extends from the lower outer side of the shell 1 to the inside of the shell 1, and a water storage sleeve 6 is fixedly connected to the upper bottom surface of the water control tank 4, and the water storage sleeve 6 is slidably sleeved on the outer side of the end of the U-shaped water storage tank 5 away from the installation groove. The water storage component also includes a water supply hose 7 fixedly connected to the outer side of the water storage sleeve 6, the water supply hose 7 is connected to the inside of the water storage sleeve 6, and the end of the water supply hose 7 away from the water storage sleeve 6 extends into the planting bin 3, and capillaries are opened on the outer side of the water supply hose 7 located inside the planting bin 3.

[0028] The filtered water will flow into the U-shaped water storage tank 5, and a U-shaped water storage space will be formed between the U-shaped water storage tank 5 and the water storage sleeve 6, and the water levels on both sides of the U-shaped water storage space will be maintained at the same height. In the process of the filtered water entering the U-shaped water storage tank 5, the water level on the other side of the U-shaped water storage space will also rise accordingly. After the water level rises to the top, the water storage in the U-shaped water storage space reaches the maximum value, and as the water source continues to enter the U-shaped water storage tank 5, the excess water source will be discharged from the top of the water storage sleeve 6 into the water source drain The water is discharged from the outlet mechanism, and under normal conditions, the water storage sleeve 6 will continue to transport water to the water supply hose 7, and the water supply hose 7 will rely on the capillaries above it to continuously input water into the soil in the planting bin 3, thereby ensuring continuous water supply and irrigation of the plants. The specific water supply flow rate of the capillaries can be changed according to the specific water demand of the plants. After the water level in the U-shaped water storage space is lower than the water supply hose 7 at the bottom, the water supply hose 7 will no longer transport water to the planting bin 3. At this time, new water needs to be injected into the U-shaped water storage space.

[0029] Through the above-mentioned arrangement, the U-shaped water storage space formed between the U-shaped water storage tank 5 and the water storage sleeve 6 can be used to store water, and combined with the water discharge mechanism, the automatic discharge of excess water can be realized, thereby effectively improving the water storage and drainage effects of the planting box. At the same time, by providing a water supply hose 7 and capillaries, the efficient use of the water source inside the U-shaped water storage tank 5 is guaranteed.

[0030] Furthermore, the filter assembly includes a first filter screen 8 fixedly connected to the side of the installation groove close to the planting bin 3, and the first filter screen 8 is fixedly connected to the side away from the planting bin 3. A plurality of sliding grooves are opened inside the shell 1, and a limiting column 10 is fixedly connected in the sliding groove. A pressure plate 11 is fixedly connected to the outside of the water control bin 4, and the pressure plate 11 is slidably sleeved on the outside of the limiting column 10. A pressure spring 12 is sleeved on the outside of the limiting column 10, and the two ends of the pressure spring 12 are respectively fixedly connected to the bottom of the pressure plate 11 and the lower surface of the sliding groove.

[0031] When water flows from the water control tank 4 into the U-shaped water storage tank 5, the first filter net 8 can filter impurities such as fallen leaves and stones in the water, while the first filter sponge 9 can filter the soil mixed in the water while ensuring the circulation of water, thereby effectively preventing soil loss.

[0032] In the process of water source infiltrating into the soil in the water control chamber 4, as the water source infiltrates, the weight of the water control chamber 4 will increase accordingly, so that the water control chamber 4 compresses the pressure spring 12 through the pressure plate 11. After the water source in the water control chamber 4 reaches saturation, the pressure spring 12 reaches the pressure limit, and the first filter screen 8 is exposed. When the soil in the water control chamber 4 no longer infiltrates into the water source, as the water source in the water control chamber 4 is lost, its weight will decrease. At this time, the pressure spring 12 will push the water control chamber 4 to slowly return to its original position upward.

[0033] Through the above-mentioned arrangement, the first filter net 8 and the first filter sponge 9 can be used to filter impurities and soil in the water source, thereby effectively preventing the loss of soil inside the planting box, and thus ensuring the planting effect of the planting box. At the same time, by setting the pressure spring 12, the water control tank 4 can automatically control the irrigation and storage of the water source according to the change of water volume, thereby effectively improving the watering effect of the plants.

[0034] Furthermore, the water source discharge mechanism includes a drainage sleeve 13 fixedly connected to the top of the bottom surface of the water control tank 4, a second filter screen 14 is fixedly connected inside the drainage sleeve 13, a second filter sponge 15 is fixedly connected above the second filter screen 14, and the top of the water storage sleeve 6 and the top of the drainage sleeve 13 are connected through a connecting pipe 16.

[0035] When the water storage capacity in the U-shaped water storage space reaches the maximum value, the water surface in the U-shaped water storage space is flush with the bottom of the connecting pipe 16, and the horizontal position of the connecting pipe 16 is slightly lower than the horizontal position of the mounting groove. Therefore, as the water source continues to enter the U-shaped water storage tank 5 from the mounting groove, the water level in the water storage sleeve 6 will gradually rise, so that the excess water source enters the drainage sleeve 13 through the connecting pipe 16 and is discharged from the bottom of the drainage sleeve 13.

[0036] Through the above arrangement, the water level change in the water storage jacket 6 can be used to automatically discharge excess water, thereby avoiding the long-term accumulation of water and causing plant death.

[0037] Furthermore, the water source discharge mechanism also includes a third filter screen 17 fixedly connected to the top of the drainage sleeve 13, a push rod 18 is fixedly connected to the top of the inner bottom surface of the shell 1, and a fourth filter screen 19 is slidably connected inside the drainage sleeve 13. The fourth filter screen 19 is located between the third filter screen 17 and the second filter sponge 15, and the push rod 18 extends from one end close to the third filter screen 17 to the top of the second filter sponge 15 and is fixedly connected to the fourth filter screen 19.

[0038] When the water control chamber 4 is filled with soil, the water storage jacket 6 is completely buried in the soil, while the lower part of the drainage jacket 13 is located in the soil, and the upper part thereof is slightly higher than the soil surface.

[0039] When the water control bin 4 is at the top and has not slid downward, the fourth filter screen 19 will press the second filter sponge 15 due to the pressure spring 12 pushing the water control bin 4, so that the water source cannot pass through the second filter sponge 15, thereby ensuring that the water source first penetrates into the soil, and as the water control bin 4 slides down, the fourth filter screen 19 moves upward relative to the second filter sponge 15, and the second filter sponge 15 will return to the filtering state, so that the water source can pass through it. Since the top of the drainage sleeve 13 is slightly higher than the soil surface, the water source accumulated on the water control bin 4 will first enter the U-shaped water storage bin 5 for storage. If too much water source accumulates on the water control bin 4, the water source above the third filter screen 17 will be directly filtered by the third filter screen 17, the fourth filter screen 19, the second filter sponge 15 and the second filter screen 14 in turn and then discharged from the bottom of the drainage sleeve 13.

[0040] Through the above arrangement, the fourth filter net 19 and the second filter sponge 15 can be used to ensure that the excess water is quickly discharged while satisfying the need for infiltration irrigation and storage of the soil, thereby effectively improving the discharge efficiency of the excess water and preventing the water from overflowing from the top of the shell 1 and causing soil loss.

[0041] Furthermore, a first outflow hole is opened below the planting bin 3, a third filter sponge 20 is fixedly connected above the first outflow hole, a second outflow hole is opened below the water control bin 4, a fourth filter sponge 21 is fixedly connected above the second outflow hole, and a discharge hole is opened below the shell 1.

[0042] When in use, the water that penetrates into the planting chamber 3 and the water control chamber 4 will be filtered by the third filter sponge 20 and the fourth filter sponge 21 respectively and then discharged from the first outlet hole and the second outlet hole, thereby preventing excessive water from penetrating into the soil and affecting plant growth, and avoiding soil loss. The discharge hole is set to discharge the water discharged from the drainage sleeve 13 and the first outlet hole and the second outlet hole from below the shell 1.

[0043] Working principle of the present invention: When in use, the planting chamber 3 and the water control chamber 4 need to be filled with soil, and the plants are planted in the planting chamber 3. In the initial state, the water control chamber 4 closes the outer filter component.

[0044] When the amount of water entering is small: the water source above the planting chamber 3 and the water control chamber 4 will directly penetrate into the soil, first meeting the watering needs of the plants. The water control chamber 4 will gradually slide down during the seepage process, and the filter component will gradually be exposed. However, since the amount of water is small and can penetrate directly, the water storage component will not enter water at this time.

[0045] When the amount of water entering is large: the water control chamber 4 will continue to slide down, exposing the filter component. When the water infiltrated into the soil in the water control chamber 4 reaches saturation, the filter component is completely exposed. At this time, a height difference is formed between the water control chamber 4 and the planting chamber 3. When the water source continues to enter, water will accumulate above the soil in the water control chamber 4, and the accumulated water above the planting chamber 3 will flow into the water control chamber 4. The accumulated water will enter the water storage component after being filtered by the filter component. The filter component can remove impurities and soil in the water. If the water storage capacity in the water storage component reaches a peak, the excess water will be discharged through the water discharge mechanism.

[0046] When there is enough water in the water storage component, it will continue to supply water to the plants in the planting chamber 3, and the water control chamber 4 will gradually return to the top as the water inside it is lost, thereby closing the filter component again.
