Description

Technical Field

[0001] The present invention relates to the technical field of agroforestry and soil and water conservation, and particularly relates to a soil water conservation planting device for a farmland shelter forest. Background Art

[0002] Agroforestry and soil and water conservation refer to protecting and rationally utilizing soil and water resources through agricultural, forestry, and engineering measures, preventing and controlling soil erosion, improving the ecological environment, and promoting the sustainable development of agriculture. Soil erosion can lead to soil degradation, loss of fertile topsoil, and a decline in land productivity. Therefore, how to make the soil retain water and soil sufficiently is an issue to be solved in current farmland forest protection and planting. Among them, rainwater collection and then reapplying the rainwater to forest protection planting is an important measure to solve this problem.

[0003] The existing collection method is to set up water storage tanks around to intercept, store, and utilize rainwater, aiming to solve water resource shortages, reduce soil erosion, and achieve the purpose of sustainable water management. However, after the rainwater is collected, it is mostly quickly applied to irrigation, with a short duration, and cannot assist in the slow decomposition of organic matter, resulting in premature depletion or evaporation of water, short water retention time, and poor sustainability. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] A soil water conservation planting device for a farmland shelter forest includes a water storage tank. A water chamber is provided on the outer periphery of the top of the water storage tank. The water storage tank is internally provided with an upper cavity and a lower cavity that communicate with each other up and down. A water storage pipe is connected between the water chamber and the lower cavity. A capillary tube is connected to the lower cavity. A floating body is provided in the lower cavity. A lifting rod is connected to the floating body. The top end of the lifting rod enters the upper cavity and is installed with a moisture retaining seat. The upper cavity is filled with a moisture retaining layer. One end of the water storage pipe connected in the lower cavity is provided with a metal bellows. The bottom of the floating body is connected with a control seat. Through the lifting actions of the floating body and the control seat, it is controlled to open and close one end of the metal bellows located in the lower cavity. The moisture retaining seat is provided with a cut-off hole.

[0006] Further preferably, a partition plate is provided in the water storage tank. The partition plate divides the water storage tank into an upper cavity and a lower cavity. The partition plate is provided with seepage holes. The upper cavity and the lower cavity communicate with each other up and down through the seepage holes. The partition plate is provided with a through hole, and a sliding sleeve is inlaid on the through hole. The lifting rod passes through the sliding sleeve.

[0007] Further preferably, a control ring is provided at the top of the upper cavity. An open hole is provided in the middle of the control ring. When the moisture retaining seat rises to the maximum position, the cut-off hole above it is covered by the control ring. The control ring is detachably connected to the top of the upper cavity.

[0008] Further preferably, a through hole is provided at the top of the water storage tank. One end of the through hole communicates with the upper cavity and is located above the control ring, and the other end of the through hole communicates with the top end of the water tank.

[0009] Further preferably, the top surface of the moisture retaining seat is provided with an upwardly convex arc surface. The intercepting hole is provided at the edge of the arc surface. A plurality of moisture retaining films are covered on the top surface of the arc surface, and reserved holes communicating with the intercepting hole up and down are provided on these moisture retaining films.

[0010] Further preferably, the moisture retaining seat is a round cake compressed from straw, leaves, wood chips, grass clippings, etc. A sleeve ring is provided at its bottom surface, and the sleeve ring is sleeved on the top end of the lifting rod. In addition to part of the moisture retaining layer in the upper cavity having the same composition as the moisture retaining seat, organic fertilizer is also filled in the moisture retaining layer.

[0011] Further preferably, the bottom surface of the floating body is provided with a downwardly concave accommodating portion. A vertical downward connecting rod is connected to the accommodating portion. The control seat is connected to the bottom end of the connecting rod. The control seat is located below the metal corrugated pipe. One end of the capillary tube connected in the lower cavity is located below the control seat and extends towards the outer periphery of the water storage tank.

[0012] Further preferably, a downwardly extending baffle is provided at the bottom edge of the moisture retaining seat. A plurality of internally and externally communicating discharge holes are annularly arranged between the water tank and the upper cavity. The baffle is slidably matched with the inner wall of the upper cavity. When the moisture retaining seat rises with the baffle, the discharge holes are opened through the position change of the baffle. When the moisture retaining seat descends with the baffle, the discharge holes are closed through the position change of the baffle.

[0013] Further preferably, a plurality of the capillary tubes and the water storage pipes are annularly arranged on the water storage tank. A plurality of the intercepting holes are annularly arranged on the moisture retaining seat. A plurality of the through holes are annularly arranged on the top of the water storage tank.

[0014] The beneficial effects of the present invention compared with the prior art are as follows:

[0015] 1. A water storage tank is provided. An annular water tank is provided above the outer circle of the water storage tank. The water storage tank is divided into upper and lower chambers. A lifting rod is arranged between the two chambers. A moisture retaining seat is provided at the top end of the lifting rod. The top surface of the moisture retaining seat is provided with a plurality of moisture retaining films. During use, the bottom section of the water storage tank is buried in a pit. The rainwater collected in the water storage tank during rainy days is moisturized by the moisture retaining seat and the moisture retaining films, reducing evaporation. When the rainwater is discharged to the roots through the capillary tubes, the application time of the stored water is extended, and the utilization rate of the rainwater is improved.

[0016] 2. During rainy days, some rainwater falls on the moisture-holding film through the open holes, and some rainwater falls into the water tank. The rainwater that falls on the moisture-holding film flows into the upper cavity, causing the moisture-holding layer filled in the upper cavity to fully absorb and expand upward. Using the expansion effect, the moisture-holding seat is lifted upward, leaving more space in the lower cavity, causing the water level in the lower cavity to rise in advance. The moisture in the lower cavity will not be differentiated to each root system by the capillary in a short time. As the water level in the water tank is continuously injected through the water storage pipe, the water level in the lower cavity will gradually rise. Through the rising action of the floating body, the moisture-holding seat at the top of the lifting rod is pushed to the bottom surface of the control ring, enabling more rainwater to quickly fill the water tank. At the same time, through the rising action of the control seat, the metal bellows is bent to cut off the circulation. In addition to injecting a certain amount of rainwater into the lower cavity, the water tank also ensures that it stores a large amount of moisture, providing a prerequisite for subsequent long-term moisture preservation for the root system. As time goes by, when the moisture in the lower cavity and the moisture that seeps into the lower cavity through the moisture-holding layer in the upper cavity are absorbed by the capillary into the root system, the water level in the lower cavity will slowly drop. The floating body will drive the connecting rod to descend, and the connecting rod will drive the control seat to descend. When the control seat descends to separate from the bottom side of the metal bellows, the tension on the metal bellows disappears, and it changes from bending upward to bending downward and returns to its original state due to the disappearance of the tension. The rainwater in the water tank enters the metal bellows through the water storage pipe and then is replenished into the lower cavity by the metal bellows. Each capillary supplies moisture to the root system, and the moisture preservation time of the root system is extended again. The water retention time is relatively long. Even without irrigation for a certain period of time, the root system can achieve long-term sustainable cultivation. The floating body in the overall components uses floating objects such as foam, and the structures of other components are simple and easy to assemble. Through the distribution of a large number of capillaries in a set of devices, the root systems of multiple surrounding forest trees can be moisturized, and the cost is relatively low.

Specific embodiments

[0024] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.

[0025] In one embodiment, as Figures 1 - 6 shown: This embodiment provides a soil water conservation planting device for farmland shelter forests, including a water storage tank 1. A water chamber 2 is provided around the top of the water storage tank 1. An upper chamber 5 and a lower chamber 6 that communicate up and down are provided inside the water storage tank 1. A water storage pipe 7 is connected between the water chamber 2 and the lower chamber 6. A capillary tube 3 is connected to the lower chamber 6. A floating body 8 is provided in the lower chamber 6. A lifting rod 9 is connected to the floating body 8. The top end of the lifting rod 9 enters the upper chamber 5 and is installed with a moisturizing seat 10. A moisturizing layer is filled in the upper chamber 5. One end of the water storage pipe 7 connected inside the lower chamber 6 is provided with a metal bellows 13. A control seat 14 is connected to the bottom of the floating body 8. By the lifting action of the floating body 8 and the control seat 14, the opening and closing of the end of the metal bellows 13 located inside the lower chamber 6 are controlled. A cut-off hole 24 is provided on the moisturizing seat 10.

[0026] Further preferably, a partition plate 4 is provided inside the water storage tank 1. The partition plate 4 divides the water storage tank 1 into an upper chamber 5 and a lower chamber 6. Seepage holes 12 are provided on the partition plate 4. The upper chamber 5 and the lower chamber 6 communicate up and down through the seepage holes 12. A through hole is provided on the partition plate 4, and a sliding sleeve 19 is inlaid on the through hole. The lifting rod 9 passes through the sliding sleeve 19.

[0027] Further preferably, a through hole 26 is provided at the top of the water storage tank 1. One end of the through hole 26 communicates with the upper chamber 5 and is located above the control ring 11. The other end of the through hole 26 communicates with the top end of the water chamber 2.

[0028] Further preferably, the top surface of the moisture retention base 10 is provided with an upwardly convex arc surface 15, the water intercepting hole 24 is opened on the edge of the arc surface 15, and a plurality of moisture retention films 16 are covered on the top surface of the arc surface 15, and reserve holes 17 communicating with the water intercepting hole 24 up and down are opened on these moisture retention films 16.

[0029] Further preferably, the bottom surface of the floating body 8 is provided with a downwardly concave accommodating portion 20, a vertically downward connecting rod 21 is connected to the accommodating portion 20, the control base 14 is connected to the bottom end of the connecting rod 21, the control base 14 is located below the metal bellows 13, and one end of the capillary tube 3 connected in the lower cavity 6 is located below the control base 14 and extends towards the periphery of the water storage tank 1.

[0030] Before use, dig a deep pit and place the water storage tank 1 into the deep pit. The depth of the deep pit should be such that after the water storage tank 1 is placed, half of the water tank 2 is above the ground. Then bury the capillary tube 3 and the water storage pipe 7 into the soil. During rainy days, part of the rainwater falls on the moisture preservation film 16 through the open holes 25, and part of the rainwater falls into the water tank 2. The rainwater that falls on the moisture preservation film 16 flows into the intercepting holes 24 through the reserved holes 17 layer by layer, and then flows into the upper cavity 5 from the intercepting holes 24. Since the upper cavity 5 is filled with a moisture preservation layer, which is a round cake compressed by straw, leaves, wood chips, grass clippings, etc., this part of the rainwater will fill the upper cavity 5 in a stored manner. At the same time, the moisture preservation layer will expand upward due to absorbing rainwater and use the expansion effect to lift the moisture preservation seat 10 upward. The rainwater in the water tank 2 flows into the lower cavity 6 through the water storage pipe 7, and this part of the rainwater is distributed to the tree roots through the capillary tube 3 to keep the roots moist. Since the water storage pipe 7 is thicker than the capillary tube 3, the moisture in the lower cavity 6 will not be differentiated by the capillary tube 3 in a short time, and the water level in the lower cavity 6 will gradually rise as the water storage pipe 7 continuously injects water. In addition, because the moisture preservation layer absorbs water and expands upward to lift the moisture preservation seat 10, the floating body 8 will drive the connecting rod 21 to rise, the connecting rod 21 will drive the control seat 14 to rise, the floating body 8 will drive the lifting rod 9 to rise, and the lifting rod 9 will drive the moisture preservation seat 10 to rise until the edge of the moisture preservation seat 10 abuts against the bottom surface of the control ring 11. At this time, the moisture preservation seat 10 will no longer rise, and the reserved holes 17 on the moisture preservation film 16 and the intercepting holes 24 on the moisture preservation seat 10 cover the bottom surface of the control ring 11. The moisture preservation seat 10 does not stop absorbing rainwater, and more rainwater enters the water tank 2 through the raised moisture preservation film 16, the top spherical surface of the moisture preservation seat 10, and the through holes 26, quickly filling the water tank 2. At the same time, through the rising action of the control seat 14, the metal bellows 13 is bent upward from its connection with the cavity wall of the water storage tank 1, preventing the fluidity of the metal bellows 13. The rainwater in the water storage pipe 7 no longer enters the metal bellows 13, and the metal bellows 13 no longer injects water into the lower cavity 6. Even if the rainwater continues to drip into the water tank 2, it will overflow outside the tank after the water level in the water tank 2 rises. The water tank 2 not only injects a certain amount of rainwater into the lower cavity 6 of the water storage tank 1 but also ensures that it stores a large amount of moisture itself, providing a prerequisite for subsequent reuse in long-term root moisture preservation.

[0031] After a sunny day, no more rainwater enters the water tank 2, nor does it fall on the moisture-holding film 16. At this time, although the water storage in the water storage tank 1 and the water tank 2 cannot be replenished in time, it can still be maintained for a long time. First, the capillary 3 is relatively thin, and its drainage speed to the root system is relatively slow. Second, the moisture in the moisture-holding seat 10 can reduce the evaporation speed under the cover of the moisture-holding film 16, enabling the moisture inhaled by the moisture-holding seat 10 to be used for a longer time. Second, in addition to the moisture-holding seat 10 sucking in a large amount of water with its filling material, it can also slowly release the water downward into the lower cavity 6. In addition, there is originally a large amount of rainwater in the lower cavity 6, and this rainwater can also be used by the capillary 3 for a long time, keeping the roots of forest trees moisturized for a long time and increasing the survival rate. As time goes by, when the water in the lower cavity 6 and the water seeping into the lower cavity 6 through the moisture-holding layer in the upper cavity 5 is absorbed by the capillary 3 and absorbed by the roots, the water level in the lower cavity 6 will slowly drop, the floating body 8 will drive the connecting rod 21 to drop, the connecting rod 21 will drive the control seat 14 to drop. When the control seat 14 drops to separate from the bottom side of the metal bellows 13, the tension on the metal bellows 13 disappears, and it changes from an upward bend to a downward bend and returns to its original state due to the disappearance of the tension. The rainwater in the water tank 2 enters the metal bellows 13 through the water storage pipe 7, and then is replenished into the lower cavity 6 by the metal bellows 13. Each capillary 3 supplies water to the roots, and the moisturizing time of the roots is extended again. The water retention time is relatively long. Even if there is no irrigation by humans for a certain period of time, the roots can be cultivated sustainably for a long time. The floating body 8 in the overall components uses floating objects such as foam, and the other component structures are simple and easy to assemble. Through the distribution of a large number of capillaries 3 in a set of devices, the roots of multiple surrounding forest trees can be moisturized, and the cost is relatively low.

[0032] When the water in the lower cavity 6 is completely drained, the control seat 14 will drop to the bottom of the cavity of the water storage tank 1, the lifting rod 9 stops dropping, the floating body 8 drops to stop close to above the metal bellows 13, and the moisture-holding seat 10 drops to stop below the control ring 11. The cut-off hole 24 on the moisture-holding seat 10 and the reserved hole 17 on the moisture-holding film 16 are opened again, and it returns to the state of receiving rainwater again.

[0033] The moisture-holding seat 10 is a round cake compressed from straw, leaves, wood chips, grass clippings, etc. A sleeve ring 18 is provided on its bottom surface, and the sleeve ring 18 is sleeved on the top end of the lifting rod 9, making the moisture-holding seat 10 easy to replace. In addition to part of the moisture-holding layer in the upper cavity 5 being the same as the composition of the moisture-holding seat 10, organic fertilizer is also filled in the moisture-holding layer. When rainwater is inhaled into the moisture-holding layer, it decomposes the organic fertilizer, and when it leaks downward into the lower cavity 6 along with the moisture in the moisture-holding layer, it improves the nutritional effect of the water in the lower cavity 6. When the water containing nutrients is discharged to the roots through the capillary 3, it improves the growth quality of forest trees.

[0034] The capillary tubes 3 and the water storage pipes 7 are several pieces arranged in an annular array on the water storage tank 1. The intercepting holes 24 are several ones arranged in an annular array on the moisturizing seat 10. The through holes 26 are several ones arranged in an annular array on the top of the water storage tank 1. During water supply, the wetting area of the soil is increased through multiple capillary tubes 3, so that a large number of roots within the range can be cultivated. During water storage, the water storage efficiency of the lower cavity 6 is improved through multiple water storage pipes 7, and at the same time, the rising speed of the floating body 8 is also accelerated.

[0035] Further preferably, a shielding cover 22 extending downward is provided on the bottom edge of the moisturizing seat 10. A plurality of internally and externally communicating discharge holes 23 are arranged in an annular array between the water tank 2 and the upper cavity 5. The shielding cover 22 is slidably fitted on the cavity wall of the upper cavity 5. When the moisturizing seat 10 rises with the shielding cover 22, the discharge holes 23 are opened through the position change of the shielding cover 22. When the moisturizing seat 10 descends with the shielding cover 22, the discharge holes 23 are closed through the position change of the shielding cover 22. When the moisturizing seat 10 rises, it is when water is stored in the lower cavity 6. At this time, through the synchronous rising action of the shielding cover 22, after the discharge holes 23 are opened, part of the rainwater in the water tank 2 can be quickly discharged into the upper cavity 5 through the discharge holes 23, assisting the intercepting holes 24 and the reserved holes 17 to enable the moisturizing layer in the upper cavity 5 to quickly absorb water. On the contrary, when the moisturizing seat 10 descends, it is when the water level in the lower cavity 6 drops. At this time, through the synchronous descending action of the shielding cover 22, the discharge holes 23 are opened. When the moisturizing film 16 on the top surface of the moisturizing seat 10 descends to below the discharge holes 23 with the moisturizing seat 10 and the discharge holes 23 are coplanar with the intercepting holes 24, part of the rainwater in the water tank 2 will flow into the intercepting holes 24 through the discharge holes 23 and flow into the upper cavity 5 through the intercepting holes 24, and it can also enable the moisturizing layer in the upper cavity 5 to quickly absorb water.

[0036] The bottom surface of the floating body 8 is provided with a downwardly concave accommodating portion 20. The setting of the accommodating portion 20 makes the bottom surface of the floating body 8 form a downwardly convex surface. When the control seat 14 descends to the bottom of the water storage tank 1, the floating body 8 stops descending, and the convex surface on its bottom surface just descends onto the metal bellows 13, pulling the bent-up metal bellows 13 downward to make them return to the unobstructed state again.

[0037] Further preferably, a control ring 11 is provided on the top of the upper cavity 5. An open hole 25 is provided in the middle of the control ring 11. When the moisturizing seat 10 rises to the maximum position, the intercepting holes 24 on it are covered by the control ring 11. The control ring 11 is detachably connected to the top of the upper cavity 5, for example, it can be connected by screws or buckles, which is convenient for maintaining the moisturizing seat 10, and when the moisturizing seat 10 is lifted upward from the top end of the lifting rod 9, it is also convenient for managing or maintaining the moisturizing layer in the upper cavity 5.

It should be understood that the above is only the specific implementation manner of the present invention and is not used to limit the protection scope of the present invention.
