[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0036] As Figures 1-7 shown, this embodiment proposes a fruit tree water and fertilizer irrigation system that can make full use of rainwater, including a housing body 1, and also including,

[0037] A water tank 4 for rainwater collection. The water tank 4 is connected to a vertical pipe 5. A floating block 51 that can float by the buoyancy of water is slidably connected in the vertical pipe 5. The water tank 4 is connected to the vertical pipe 5 through a connecting pipe, and a first solenoid valve is provided on the connecting pipe. By controlling the first solenoid valve, the connection between the water tank 4 and the vertical pipe 5 can be controlled. Based on the principle of the communicating vessel, the height of the water level inside the vertical pipe 5 is the water level height of the water tank 4.

[0038] A mixing tank 8 for water and fertilizer mixing. The mixing tank 8 is rotatably connected to a stirring rod 81. The stirring rod 81 is connected to a motor 82. The motor 82 is fixedly connected to the outer wall of the mixing tank 8. One end of the stirring rod 81 passes through the mixing tank 8 and is connected to the motor 82. The motor 82 drives the stirring rod 81 to rotate, thereby realizing the mixing of water and fertilizer inside the mixing tank 8.

[0039] It also includes an irrigation pipe 83, which is distributed at appropriate positions in the fruit orchard. The mixing tank 8 is connected to a delivery pump for delivering fertilizer. One end of the delivery pump is connected to the mixing tank 8, and the other end is connected to the irrigation pipe 83. The delivery pump can deliver the mixed water and fertilizer into the irrigation pipe 83 to achieve the irrigation of fruit trees.

[0040] A delivery mechanism that can deliver fertilizer into the mixing tank 8. The delivery mechanism can deliver fertilizer into the mixing tank 8. The water tank 4 is connected to the mixing tank 8 through a water delivery pipe, and a second solenoid valve is connected to the water delivery pipe. The rainwater collected in the water tank 4 can be delivered into the mixing tank 8 through the water delivery pipe. By opening the second solenoid valve, the connection between the water tank 4 and the mixing tank 8 can be realized.

[0041] The water tank 4 can collect the treated rainwater. By mixing the treated rainwater and fertilizer for the irrigation of water and fertilizer, it can make full use of the rainwater, realize the mixing of water and fertilizer, and then irrigate the fruit trees, effectively saving water resources and reducing the cost of fertilization and irrigation. The method of mixing water and fertilizer for fertilization and irrigation can achieve the production effect of reducing fertilizer use and increasing efficiency.

[0042] The housing 1 is also fixedly connected with a water collecting plate 2 arranged in an inclined direction. The angle of the water collecting plate 2 is appropriate enough to facilitate the collection of rainwater. In addition, a solar panel can be arranged on the water collecting plate 2, and the overall energy supply of the device can be realized through the solar panel.

[0043] The housing 1 is fixedly connected with a water collecting trough 3. One end of the water collecting trough 3 is communicated with the water collecting plate 2, and the other end of the water collecting trough 3 is communicated with the water tank 4. The water collecting plate 2 is recessed towards the direction of the water collecting trough 3. The water collecting trough 3 is arranged vertically. Through the arranged water collecting trough 3, the rainwater collected on the water collecting plate 2 can flow into the water collecting trough 3.

[0044] In addition, in order to better utilize the rainwater, the water collecting trough 3 first passes through a sand and gravel filter, then through a primary filter 9 and a secondary filter 10, and finally flows into the water tank 4. The primary filter 9 is a mesh filter, and the secondary filter 10 is a disc filter. The specific process is that it first passes through the sand and gravel filter, then passes through the mesh filter for one filtration, and then goes to the disc filter for the final fine filtration, realizing three-stage filtration.

[0045] In addition, regarding the collection of water volume, the water in the gullies or other positions in the orchard can be collected, thereby reducing the occurrence of waterlogging and providing sufficient water for irrigation. The collected water needs to be filtered in three stages and then flow into the water tank 4 for storage.

[0046] The housing 1 is slidably connected with a lifting box 7. The lifting box 7 can only slide in the vertical direction. The lifting box 7 is connected with the housing 1 through a spring 78. One end of the spring 78 is connected with the housing 1, and the other end of the spring 78 is connected with the lifting box 7. The lifting box 7 is also communicated with a drain pipe 73.

[0047] A water blocking ball 77 that can block the drain pipe 73 is arranged in the drain pipe 73. In the initial state, the gravity of the water blocking ball 77 can make the drain pipe 73 in a blocked state. The housing 1 is fixedly connected with a top rod 74 arranged directly below the water blocking ball 77. When the lifting box 7 descends, after the top rod 74 contacts the water blocking ball 77, it can drive the water blocking ball 77 to rise. At this time, the drain pipe 73 is opened, and the water outlet of the lifting box 7 can be realized.

[0048] The housing body 1 is fixedly connected with a conductive block 72, and the lifting box 7 is fixedly connected with a conductive slider 71. When the conductive block 72 and the conductive slider 71 are in contact, the motor and the conveying mechanism can be powered on to work. The longer the contact time between the conductive block 72 and the conductive slider 71, the longer the power-on time of the motor and the conveying mechanism. By means of power on and off, it is more beneficial to control the motor and the conveying mechanism.

[0049] The lifting box 7 is fixedly connected with a water outlet pipe 76, and the vertical pipe 5 is provided with a water drain pipe 54. When the water outlet pipe 76 descends to be connected with the water drain pipe 54, the water outlet of the vertical pipe 5 can be realized.

[0050] The lifting box 7 is provided with a clamping groove 75, and the vertical pipe 5 is slidably connected with a clamping rod 55 that can slide into the clamping groove 75. The clamping rod 55 is connected with the vertical pipe 5 through a tension spring 53. The tension spring 53 is sleeved on the clamping rod 55. The left end of the tension spring 53 is connected with the vertical pipe 5, and the right end of the tension spring 53 is connected with the clamping rod 55. Under the elastic force of the tension spring 53, the clamping rod 55 can slide into the clamping groove 75.

[0051] The floating block 51 is connected with a magnet 52 that has an attracting effect on the clamping rod 55. The elastic force of the magnet 52 is greater than the elastic force of the tension spring 53. Therefore, the magnet 52 can move the clamping rod 55 in a direction away from the clamping groove 75, stretch the tension spring 53, and enable the clamping rod 55 to move out of the clamping groove 75, thereby releasing the limiting effect of the clamping rod 55 on the lifting box 7 and facilitating the reset of the lifting box 7.

[0052] The lower surface of the clamping groove 75 includes an inclined surface and a horizontal surface. When the clamping rod 55 slides from the inclined surface into the horizontal surface, the elastic force of the tension spring 53 can drive the water outlet pipe 76 to continue to descend. As the lifting box 7 descends, the lifting box 7 first descends until the clamping rod 55 contacts the inclined surface. At this time, under the elastic force of the tension spring 53, the lifting box 7 can be further pushed downward, so that the water outlet pipe 76 and the water drain pipe 54 can communicate with a sufficient area to facilitate water outlet.

[0053] In the initial state, under the elastic force of the spring 78, there is a gap between the water blocking ball 77 and the ejector rod 74, a gap between the conductive block 72 and the conductive slider 71, and the water outlet pipe 76 and the water drain pipe 54 are arranged in a dislocation manner. When the lifting box 7 descends and the clamping rod 55 slides into the clamping groove 75, at this time, the conductive block 72 and the conductive slider 71 just come into contact, and the motor and the conveying mechanism are powered on to work.

[0054] The ejector rod 74 just pushes up the water blocking ball 77. At this time, the clamping rod 55 realizes the limit of the lifting box 7, the drain pipe 73 is opened, the water outlet of the lifting box 7 is realized, the water outlet pipe 76 and the water drain pipe 54 are connected, the water outlet of the vertical pipe 5 is realized, and by reasonably adjusting the apertures of the water outlet pipe 76 and the water drain pipe 54, the water outlet speed of the vertical pipe 5 is adjusted, and further the power-on time of the motor and the conveying mechanism is adjusted.

[0055] The working time of the motor and the conveying mechanism is proportional to the amount of rainwater collected by the water tank 4. The more rainwater the water tank 4 collects, the higher the water level in the vertical pipe 5. At this time, the water outlet time of the vertical pipe 5 is longer. The vertical pipe 5 can drive the conductive slider 71 to move. When the vertical pipe 5 discharges water, the conductive slider 71 moves to contact the conductive block 72 at this time, and the motor 82 and the conveying mechanism are powered on to work, so that the stirring time is longer and more fertilizer is conveyed, making the discharge amount of fertilizer match the amount of rainwater collected, so as to better mix water and fertilizer.

[0056] The housing 1 is also fixedly connected with a water box 6. The water box 6 is provided with a drip pipe 61 with an adjustable opening size. The water in the drip pipe 61 can drip into the lifting box 7. The drip pipe 61 is rotatably connected with an adjusting pipe 62. The adjusting pipe 62 is provided with a water outlet hole. By rotating the adjusting pipe 62, the communication area between the water outlet hole and the drip pipe 61 can be adjusted, so as to realize the adjustment of the dripping speed.

[0057] The water in the water box 6 can drip into the lifting box 7. When the lifting box 7 descends to a certain extent, at this time, the clamping rod 55 slides into the clamping groove 75, and the communication between the lower water pipe 54 and the water outlet pipe 76 can be realized, and the water outlet work of the vertical pipe 5 can be carried out. At this time, the setting of the clamping rod 55 can keep the lower water pipe 54 and the water outlet pipe 76 in a communicating state all the time, so that the vertical pipe 5 has enough time to discharge water.

[0058] After the water outlet is over, the floating block 51 descends. The floating block 51 can make the clamping rod 55 slide out of the clamping groove 75. At this time, the lifting box 7 can be reset. By means of dripping water, the timing function is realized. Each time it is used, by adjusting the amount of water in the water box 6 each time or adjusting the dripping speed of the drip pipe 61, the working interval time of the motor and the conveying mechanism can be adjusted. There is no need for complex control, and long-term timing can be carried out. In a pure mechanical way, the structure is more reliable, it can be better applied to the field environment, is not affected by the weather, is easy to install, has a low cost, and is convenient to maintain.

[0059] A method for using a fruit tree water and fertilizer irrigation system that can make full use of rainwater. Using the above-mentioned fruit tree water and fertilizer irrigation system that can make full use of rainwater, it includes the following steps:

[0060] S1: The water tank 4 collects rainwater. The water in the water box 6 drips into the lifting box 7. As the lifting box 7 descends, when the lifting box 7 descends to the inclined plane of the clamping rod 55 and the clamping groove 75 in contact, at this time, under the action of the elastic force of the tension spring 53, the lifting box 7 is further pushed downward;

[0061] S2: When the clamping rod 55 slides into the horizontal plane of the clamping groove 75, the clamping rod 55 limits the lifting box 7 at this time. The water outlet pipe 76 is communicated with the lower water pipe 54, and the water in the vertical pipe 5 is discharged, causing the floating block 51 to descend. The ejector rod 74 pushes up the water blocking ball 77, and the drain pipe 73 is opened to discharge the water in the lifting box 7. The conductive block 72 contacts the conductive slider 71, and the motor 82 and the conveying mechanism are powered on to work. The conveying mechanism conveys the materials into the mixing tank 8, and the motor 82 mixes the water and fertilizer in the mixing tank 8;

[0062] S3: When the floating block 51 descends to one side of the clamping rod 55, the magnet 52 drives the clamping rod 55 to move out of the clamping groove 75, stretching the tension spring 53. The clamping rod 55 releases the limit on the lifting box 7, and the spring 78 drives the lifting box 7 to reset. At this time, the conductive block 72 and the conductive slider 71 are separated, and the motor and the conveying mechanism stop working. Then, the subsequent irrigation of the fruit trees is carried out.

[0063] In S2, when the conductive block 72 contacts the conductive slider 71, the first solenoid valve is disconnected. At this time, the water in the water tank 4 will not flow into the vertical pipe 5, which is convenient for the water discharge of the vertical pipe 5. The second solenoid valve is opened, and the water in the water tank 4 flows into the mixing tank 8. This setting method can facilitate the control of the water inflow, thereby facilitating the precise ratio of water and fertilizer.

[0064] There is also another implementation method: when the conductive block 72 contacts the conductive slider 71, the first solenoid valve and the second solenoid valve may no longer be set. The water in the water tank 4 can directly flow into the mixing tank 8 through the vertical pipe 5, then through the lower water pipe 54 and the water outlet pipe 76. This setting method is convenient for the overall control of the device.

[0065] In addition, the conductive slider 71 is connected with an induction metal sheet, and the conductive block 72 is connected with a proximity switch. The proximity switch is a position switch that can operate without mechanical direct contact with the moving parts. When the induction metal sheet approaches the induction surface of the proximity switch to the action distance, the switch can act without mechanical contact and applying any pressure, thereby driving a DC electrical appliance or providing a control instruction for a computer (PLC) device.

[0066] After the conductive block 72 contacts the conductive slider 71, the proximity switch senses the induction metal sheet at this time. The proximity switch can control the conveying pump to work. The conveying pump can convey the water and fertilizer in the mixing tank 8 into the irrigation pipe 83 to achieve the irrigation of water and fertilizer. The conveying pump can be connected with a delay switch. The conveying pump starts to work after a delay of T time. The T time is convenient for the water and fertilizer in the mixing tank 8 to be fully mixed.

[0067] Among them, the operation of the transfer pump is not necessary. According to the planting situation, it is possible to choose to only perform water and fertilizer mixing without fertilization irrigation. For orchards with poor drainage, waterlogging is likely to occur in the orchard. After the waterlogging is drained, fertilization irrigation can be carried out in a timely manner. For orchards with serious soil erosion, the nutrients in the soil will be severely lost, so more fertilizers need to be applied to supplement the nutrients.

[0068] Waterlogging after rainfall will cause the roots to be unable to breathe, affecting the absorption of fertilizers. When mixing water and fertilizers, it is particularly important to supplement phosphorus and calcium elements. Phosphorus promotes the growth of the main roots, and calcium promotes the development of fine roots, which helps the roots to recover. At this time, appropriate fertilizers can be transported to the mixing tank 8 through the conveying mechanism. When the soil humidity is moderate after rain, underground topdressing can be carried out through the irrigation pipe 83.

[0069] Under the existing planting environment, a large amount of nitrogen is lost through ammonia volatilization, nitrification and denitrification, and nitrate leaching, causing serious non-point source pollution. In hilly areas, peaches have become an important source of farmers' income increase. However, most peach orchards face problems such as excessive application of chemical fertilizers, decline in cultivated land quality, damage to the soil ecological environment, and frequent pollution. After a certain number of years, the peach orchards will face problems such as an increase in soil toxins, a decline in peach quality, and a reduction in quantity. However, peach trees are perennial fruit trees that like both light and fertilizer. The growth situation of the tree body in the current year has a direct relationship with the yield and quality of peach trees in the next year, which is mainly manifested in the quality of flower bud formation, the amount of stored nutrients, and the integrity of leaf protection in the current year.

[0070] Through the rational utilization of organic nutrient resources, the present invention replaces part of the chemical fertilizers with organic fertilizers to achieve a fertilization system of combined application of organic and inorganic fertilizers. In terms of the long-term yield increase effect, the yield increase effect of organic fertilizers is better than that of chemical fertilizers. The continuous mineralization and residual effect superposition of nutrients in organic fertilizers can provide continuous nutrient supply for crops. Applying organic fertilizers can also improve the basic soil fertility of cultivated land, increase the content of soil alkaline hydrolyzable nitrogen, available phosphorus, and available potassium, and replace the external chemical fertilizer nutrient input with the internal nutrients in the cultivated land, so as to achieve the production effect of reducing fertilizer use and increasing efficiency.

[0071] Scale and comprehensive benefits: Through the implementation of the present invention, an efficient operation mechanism for the transformation of old and new driving forces in modern agriculture is formed. Waste materials such as straw and fruit tree branches are collected and composted near the orchard. The carbon-nitrogen ratio is measured by agricultural experts, and then toilet feces and livestock manure are mixed in proportion for fermentation, and relevant bacterial strains are added. After two months of fermentation, special organic fertilizers suitable for Feicheng peaches can be produced.

[0072] The cost of organic fertilizers produced from toilet feces and livestock manure by large-scale treatment plants is relatively high, making it difficult to promote on a large scale. The fertilizer applied in this application, however, is a new technology that uses manure in combination with agricultural waste such as branches and straw for composting treatment, solving the problems of difficult treatment of agricultural waste and liquid manure, reducing the cost of organic fertilizers, and improving the quality of Feicheng peaches.

[0073] In addition, the biogas slurry produced after collecting rural waste for resource utilization is absorbed and utilized by fruit trees through the fruit tree water and fertilizer irrigation system. At the same time, components such as medium and trace elements, humic acid, and amino acids can be added to the system according to the nutritional requirements of the tree body. In the future, it will be possible to gradually connect multiple planting bases to form an industrial park public biogas slurry water and fertilizer integration system. Through the harmless treatment and utilization of biogas slurry, a peach ecological circular agriculture area can be constructed.

[0074] Ecological benefits: By growing grass in the orchard, the microclimate of the orchard is improved, and the soil environment of the orchard is improved, which is conducive to the comprehensive management of fruit tree pests and diseases, forming a relatively persistent ecological system in the orchard, promoting the growth and development of fruit trees, and improving the quality and yield of fruits.

[0075] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.

The magnet (52) can move the clamping rod (55) in a direction away from the clamping groove (75); the lower surface of the clamping groove (75) includes an inclined surface and a horizontal surface. When the clamping rod (55) slides from the inclined surface into the horizontal surface, the elastic force of the tension spring (53) can drive the water outlet pipe (76) to continue descending; It includes the following steps: S1: The water tank (4) conducts rainwater collection work. The water in the water box (6) drips into the lifting box (7). As the lifting box (7) descends, when the lifting box (7) descends to contact the inclined surface of the clamping rod (55) and the clamping groove (75), at this time, under the action of the elastic force of the tension spring (53), the lifting box (7) is further pushed downward; S2: When the clamping rod (55) slides into the horizontal plane of the clamping groove (75), the clamping rod (55) limits the lifting box (7) at this time. The water outlet pipe (76) and the lower water pipe (54) are connected, and the water outlet of the vertical pipe (5) is realized, causing the floating block (51) to descend. The ejector rod (74) pushes up the water blocking ball (77), and the drain pipe (73) is opened to realize the water outlet of the lifting box (7). The conductive block (72) and the conductive slider (71) are in contact, and the motor (82) and the conveying mechanism are powered on to work. The conveying mechanism conveys the materials into the mixing tank (8), and the motor (82) realizes the mixing work of the water and fertilizer in the mixing tank (8); S3: When the floating block (51) descends to one side of the clamping rod (55), the magnet (52) drives the clamping rod (55) to move out of the clamping groove (75), stretching the tension spring (53). The clamping rod (55) releases the limit on the lifting box (7), and the spring (78) drives the lifting box (7) to reset. At this time, the conductive block (72) and the conductive slider (71) are separated, and the motor and the conveying mechanism stop working. Then, the subsequent irrigation of the fruit trees is carried out; The more rainwater collected by the water tank (4), the higher the water level of the vertical pipe (5). At this time, the water outlet time of the vertical pipe (5) is longer. The vertical pipe (5) drives the conductive slider (71) to move. When the vertical pipe (5) discharges water, the conductive slider (71) moves to contact the conductive block (72) at this time. The motor (82) and the conveying mechanism are powered on to work, so that the stirring time is longer and more fertilizer is conveyed, making the discharge amount of fertilizer match the collected amount of rainwater.
