Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting equipment, and in particular relates to a water-saving and fertilizer-saving integrated planting equipment. Background Art

[0002] In the process of agricultural sowing and planting, it is necessary to provide seeds with an appropriate amount of water to increase the germination rate of seeds, which mainly relies on the water stored in the soil. If the soil moisture content cannot meet the water required for seed germination and seedling growth, artificial irrigation must be used to supplement the water. In the process of seed planting and germination, the frequency and amount of fertilization are also important factors affecting its growth. The integrated water-fertilizer technology can combine irrigation with fertilization. Through the irrigation system, water and fertilizer are directly supplied to the roots of crops in proportion, realizing the efficient use of water resources and fertilizers. It not only significantly improves the yield and quality of crops, but also reduces the use of chemical fertilizers and water resources. The integrated water-fertilizer technology is generally used in areas with poor soil conditions, where water and nutrients are easily lost, areas with tight water resources, and facilities agriculture that require precise control of the crop growth environment.

[0003] When using water-fertilizer integration technology for irrigation, different types of water-soluble fertilizers have different water-soluble ratios, for example: ‌Powdered water-soluble fertilizer‌: 5 kg of powdered water-soluble fertilizer of a large number of elements should be diluted with 800-1000 kg of water. Therefore, 1 jin of powdered water-soluble fertilizer should be diluted with 80 to 100 kg of clean water.

[0004] Liquid water-soluble fertilizer: Liquid fertilizer is applied in barrels with 3-4 liters per acre. The water consumption is about 1 ton per acre. Therefore, the amount of water to be added to 1 jin of liquid water-soluble fertilizer is 250 to 350 kilograms of clean water.

[0005] ‌Water-soluble fertilizers containing medium and trace elements‌: These fertilizers are mostly applied by foliar spraying. The amount of water to be added is, for example, 35g of Molfeng is added to 15kg of water. Therefore, the amount of water to be added to 1 jin of water-soluble fertilizers containing medium and trace elements is 100 to 150kg of clean water.

[0006] Functional water-soluble fertilizer: Functional water-soluble fertilizer is a kind of fertilizer specially formulated for a certain type of farmland. It is applied as basal fertilizer, broadcasting fertilizer and topdressing fertilizer at a rate of 15-30 kg per mu each time, and as flushing fertilizer at a rate of 8-15 kg per mu each time. Therefore, the amount of water to be added to 1 jin of functional water-soluble fertilizer is 80 to 100 kg of clean water.

[0007] The prior art generally mixes water and fertilizer by setting up a larger water reservoir. However, due to the limited capacity of the water reservoir, the water-fertilizer mixture needs to be continuously replenished in the water reservoir when large-scale irrigation is carried out. If the water in the water reservoir is replenished before it is completely pumped out, the amount of water remaining in the water reservoir cannot be determined, resulting in uncertain amount of fertilizer added and inaccurate water-fertilizer ratio.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0031] In addition, it should be noted that the connections involved in the present invention can be achieved by using conventional connection methods and do not involve any innovation.

[0032] The subject of the present invention is a water-saving and fertilizer-saving integrated planting equipment. In the process of agricultural sowing and planting, it is necessary to provide an appropriate amount of water for the seeds to improve the germination rate of the seeds, which mainly relies on the water stored in the soil. If the soil moisture content cannot meet the water required for seed germination and seedling growth, artificial irrigation must be adopted to supplement the water. In the process of seed planting and germination, the frequency and amount of fertilization are also important factors affecting its growth. The water-fertilizer integration technology can combine irrigation and fertilization, and directly supply water and fertilizer to the roots of crops in proportion through the irrigation system, realizing the efficient utilization of water resources and fertilizers, which not only significantly improves the yield and quality of crops, but also reduces the use of chemical fertilizers and water resources. The water-fertilizer integration technology is generally used in areas with poor soil conditions, where water and nutrients are easily lost, areas with tight water resources, and facility agriculture that requires precise control of the crop growth environment.

[0033] The water ratio of different types of water-soluble fertilizers: ‌Powdered water-soluble fertilizer‌: 5 kg of powdered water-soluble fertilizer of a large number of elements should be diluted with 800-1000 kg of water. Therefore, 1 jin of powdered water-soluble fertilizer should be diluted with 80 to 100 kg of clean water.

[0034] Liquid water-soluble fertilizer: Liquid fertilizer is applied in barrels with 3-4 liters per acre. The water consumption is about 1 ton per acre. Therefore, the amount of water to be added to 1 jin of liquid water-soluble fertilizer is 250 to 350 kilograms of clean water.

[0035] ‌Water-soluble fertilizers containing medium and trace elements‌: These fertilizers are mostly applied by foliar spraying. The amount of water to be added is, for example, 35g of Molfeng is added to 15kg of water. Therefore, the amount of water to be added to 1 jin of water-soluble fertilizers containing medium and trace elements is 100 to 150kg of clean water.

[0036] Functional water-soluble fertilizer: Functional water-soluble fertilizer is a kind of fertilizer specially formulated for a certain type of farmland. It is applied as basal fertilizer, broadcasting fertilizer and topdressing fertilizer at a rate of 15-30 kg per mu each time, and as flushing fertilizer at a rate of 8-15 kg per mu each time. Therefore, the amount of water to be added to 1 jin of functional water-soluble fertilizer is 80 to 100 kg of clean water.

[0037] The prior art generally mixes water and fertilizer by setting up a larger water reservoir. The capacity of the water reservoir is limited. When irrigating a large area, the water-fertilizer mixture needs to be continuously replenished in the water reservoir. If the water in the water reservoir is replenished after it is pumped out, the process of refilling the water takes time; if the water in the water reservoir is replenished before it is completely pumped out, the amount of water remaining in the water reservoir cannot be determined, resulting in uncertain amount of fertilizer added and inaccurate water-fertilizer ratio.

[0038] Based on the above reasons, the present invention provides a water-saving and fertilizer-saving integrated planting equipment to solve the above-mentioned technical problems. Figures 1 to 8 , the present invention is described in detail.

[0039] Example 1 This embodiment provides a water-saving and fertilizer-saving integrated planting device, such as Figure 1 As shown, it includes a first pipe fitting 1, a second pipe fitting 2, a baffle 3, and a linear displacement component 6.

[0040] The first pipe 1 is provided with an inlet on its side, the upper end of the first pipe 1 is closed, and the lower end is provided with an outlet. The first pipe 1 includes a diameter reducing section, and the diameter reducing section has an inner wall with a conical surface. The first pipe 1 is used to transport water. The diameter of the second pipe 2 is smaller than the diameter of the first pipe 1. One end of the second pipe 2 is arranged inside the first pipe 1, and the other end passes through the upper end of the first pipe 1. The second pipe 2 slides up and down with the first pipe 1 and is sealed. The second pipe 2 is used to transport fertilizer. The baffle 3 is arranged inside the first pipe 1, and the baffle 3 is connected to the second pipe 2. The baffle 3 is used to match the conical surface of the diameter reducing section. The linear displacement component 6 is arranged between the first pipe 1 and the second pipe 2. The linear displacement output end of the linear displacement component 6 is connected to the first pipe 1, and is used to drive the first pipe 1 to move axially relative to the second pipe 2; when the first pipe 1 moves axially, the distance between the baffle 3 and the conical surface of the diameter reducing section is changed, and the water flow in the first pipe 1 is adjusted, thereby adjusting the water-fertilizer ratio.

[0041] In order to prevent the fertilizer from flowing downward under the action of gravity and causing part of the water to be free of fertilizer, the first pipe member 1 and the second pipe member 2 are both arranged vertically, and the outlet of the second pipe member 2 is arranged in the middle position of the first pipe member 1.

[0042] When in use, the inlet of the first pipe 1 is connected to the water pipe, and water is supplied by a water pump. The second pipe 2 is connected to the water-soluble fertilizer delivery pipe. Liquid fertilizer can be added directly, and solid fertilizer needs to be dissolved in advance before adding.

[0043] When the first pipe 1 and the second pipe 2 start conveying water at the same time, a certain amount of fertilizer can be directly added to the water during the water conveying process, thereby improving the accuracy of the water-fertilizer mixing ratio.

[0044] The ratio of the water flow rate passing through the first pipe fitting 1 to the fertilizer flow rate passing through the second pipe fitting 2, i.e., the water-fertilizer ratio, is driven by the linear displacement component 6 to move the first pipe fitting 1 up and down relative to the second pipe fitting 2, thereby changing the distance between the baffle and the reducing section, thereby adjusting the water flow rate of the first pipe fitting 1, and further adjusting the water-fertilizer ratio.

[0045] In order to adjust the water-fertilizer ratio without affecting the normal flow of water and avoid excessive resistance of the baffle 3 to water, the baffle 3 is set to be conical, and the conical baffle 3 matches the conical surface of the reducing section of the first pipe fitting 1 to form a smooth transition. The upper end of the baffle 3 is fixed to the second pipe fitting 2, and the lower end of the second pipe fitting 2 is located on the inner side of the baffle 3.

[0046] Working principle of this embodiment The planting equipment provided in this embodiment, when in use, the first pipe fitting is connected to the water delivery pipe, and the second pipe fitting is connected to the fertilizer delivery pipe. When in use, water and fertilizer can be introduced simultaneously using pumps respectively. The outlet of the first pipe fitting is connected to the inlet of the irrigation water pipe. The irrigation water pipe is selected to a suitable length according to needs. Sufficient length is more conducive to the full integration of fertilizer and water. In this way, it is possible to deliver water while adding fertilizer, and there is no need to add an additional water reservoir and then carry out the water-fertilizer mixing process in the water reservoir in advance; and a linear displacement component is provided between the first pipe fitting and the second pipe fitting, and the linear displacement component is used to drive the first pipe fitting and the second pipe fitting to move relative to each other. When the first pipe fitting moves, the size of the channel between the first pipe fitting and the second pipe fitting can be adjusted through the mutual cooperation between the conical surface and the baffle, thereby adjusting the water intake, and can adjust different water flow rates according to the needs of different fertilizers, thereby adjusting the water-fertilizer ratio, and further improving the accuracy of the water-fertilizer blending ratio.

[0047] Example 2 In order to evenly divert the fertilizer into the water, a first diverter assembly 5 is provided at the bottom of the baffle 3. The first diverter assembly 5 has an inlet and multiple outlets. The inlet is toward the lower end of the second pipe fitting 2, and the multiple outlets are all toward the inner wall of the first pipe fitting 1. The multiple outlets are evenly distributed along the circumference of the first pipe fitting 1, and are used to divert the fertilizer, thereby further improving the accuracy of the water-fertilizer mixing ratio.

[0048] like Figure 2 and Figure 3 As shown, in order to make the fertilizer discharged from multiple outlets have a certain initial velocity in the horizontal direction, the first diversion component 5 in this embodiment includes a box body 501, a plurality of first blades 502, and a plurality of second blades 503. The top of the box body 501 is open, and the box body 501 is rotatably arranged at the bottom of the baffle 3. The circumferential surface of the box body 501 is provided with a plurality of through holes. The plurality of first blades 502 are fixedly arranged on the outer circumferential surface of the box body 501. The first blade 502 is a spiral blade. The purpose is to drive the box body 501 to rotate by hydraulic force under the action of the spiral blade. The second blade 503 is arranged at the inner bottom of the box body 501, and the plurality of second blades 503 are evenly distributed around the circumference of the second pipe 2.

[0049] The water inside the first pipe 1 flows downward, and the pressure of the water flow in the vertical direction generates a horizontal component force on the first blade 502 when the water flows through, and the component force pushes the first blade 502 and the baffle 3 to rotate. When the baffle 3 rotates, the fertilizer in the box body 501 generates centrifugal force, flows circumferentially, and thus flows out from the through holes on the peripheral surface of the box body 501 into the water, and in the process of flowing out, the fertilizer can be rotated into the water under the action of centrifugal force, thereby further refining the ratio of water-fertilizer mixing and improving the accuracy of the mixing ratio.

[0050] After the fertilizer is mixed into the water, in order to keep the fertilizer and water mixed evenly during transportation, a stirring shaft 7 is fixedly connected to the bottom of the box body, and a plurality of stirring rods 8 are arranged on the stirring shaft 7. The plurality of stirring rods 8 are evenly arranged around the stirring shaft 7, and the stirring rods 8 are fixedly connected to the stirring shaft 7.

[0051] When the water force pushes the box body 501 to rotate, the box body 501 drives the stirring shaft 7 to rotate, and the stirring shaft 7 drives the stirring rod 8 to rotate synchronously, thereby stirring the mixed water and fertilizer to improve the uniformity of the water and fertilizer mixing.

[0052] In order to increase the tangential force of the fertilizer in the process of flowing in the circumferential direction, so that the fertilizer is fully swirled into the water and fully mixed with the water, the second blades 503 are set as arc-shaped plates, and a spacing is left between two adjacent second blades 503. The center position formed by all the second blades 503 is set directly below the outlet of the second pipe 2, and all the spacings are equal, in order to make the fertilizer flow out evenly from between two adjacent second blades 503, so that the proportion of the fertilizer diverted into the water flow is the same.

[0053] Working principle of this embodiment The planting equipment provided in this embodiment requires that both the first pipe and the second pipe are arranged vertically when in use, and the fertilizer enters from the inlet and is discharged from multiple outlets, and the outlets are oriented toward the inner wall of the first pipe, and the fertilizer discharged from the multiple outlets is evenly distributed in the water around the first pipe. Since the box body is rotatably arranged at the bottom of the baffle, the box body is driven to rotate by the first blade during the flow of water inside the first pipe, and the fertilizer in the box body can be discharged from multiple through holes on the peripheral surface during the rotation of the box body, so that the fertilizer is evenly distributed in the water flow on the peripheral surface.

[0054] Example 3 On the basis of the above embodiment, in order to further improve the accuracy of the water-fertilizer mixing ratio, as Figure 4 As shown, in this embodiment, a second diverter assembly 4 is arranged outside the baffle 3, and the second diverter assembly 4 includes a ring 401 and a plurality of partitions 402. The ring 401 is arranged at the bottom of the baffle 3, and the ring 401 is fixedly connected to the baffle 3. The plurality of partitions 402 are evenly distributed on the outer peripheral surface of the ring 401, and the partitions 402 are connected to the ring 401.

[0055] The above-mentioned embodiment 2 is to split the fertilizer, while this embodiment is to split the water. By arranging a plurality of partitions 402 on the water flow surface, the water flow can be divided, so that the split fertilizer is mixed into different water flow streams respectively, further improving the uniformity of mixing.

[0056] Among them, Figure 7As shown, the specific arrangement of the box body 501 rotatably arranged at the bottom of the baffle 3 is that an annular boss 504 is arranged on the outer peripheral surface of the box body 501, and a slide groove is arranged on the ring member 401, and the slide groove is slidably connected with the boss 504.

[0057] In order to avoid interference between the first pipe 1 and the partition 402 during the up and down movement, Figure 4 and Figure 5 As shown, a slide groove is provided on the ring 401, and the partition 402 is slidably and sealedly connected to the slide groove. An elastic member 403 is provided between the partition 402 and the second pipe 2. One end of the elastic member 403 is fixed to the second pipe 2, and the other end is fixed to the partition 402. A wedge surface is provided on the end of the partition 402 located outside the ring 401.

[0058] like Figure 1 and Figure 5 As shown, in a normal state, the partition 402 is pressed against the inner wall of the first pipe 1 under the action of the elastic member 403. When the first pipe 1 moves downward, the conical surface of the inner wall of the first pipe 1 matches the wedge surface at the end of the partition 402, and the first pipe 1 moves downward to push the partition 402 to move toward the second pipe 2. The partition 402 compresses the elastic member 403. When the first pipe 1 moves upward, under the action of the restoring force of the elastic member 403, the partition 402 moves toward the inner wall of the first pipe 1 to achieve restoration.

[0059] like Figure 7 As shown, in order to limit the partition 402 from moving in the horizontal direction, limit plates are provided above and below the partition 402 , and the limit plates are fixedly connected to the ring 401 .

[0060] In order to provide space for the elastic member 403, as Figure 5 As shown, a support ring is provided on the outside of the second pipe fitting 2, and at least two connecting rods are provided between the support ring and the second pipe fitting 2, one end of the connecting rod is fixed to the second pipe fitting, and the other end is fixed to the support ring, and the elastic member 403 is provided on the support ring and the partition 402 bracket, one end of the elastic member 403 is fixedly connected to the support ring, and the other end is fixedly connected to the partition 402.

[0061] In order to further improve the accuracy of the water-fertilizer mixing ratio, the number of partitions 402 is the same as the number of second blades 503. The partitions 402 divide the water between the first pipe 1 and the second pipe 2 into multiple water streams, and the second blades 503 divide the fertilizer in the box body 501 into multiple fertilizer streams.

[0062] In order to avoid the situation where the first blade 502 is located between two water streams when the first blade 502 is located directly below the partition 402 , resulting in the water flow being unable to push the first blade 502 , the number of the first blades 502 is different from the number of the partitions 402 .

[0063] Working principle of this embodiment The planting equipment provided in this embodiment, when in use, is evenly arranged between the first pipe fitting and the second pipe fitting, and the partitions can divert the water flow between the first pipe fitting and the second pipe fitting, thereby dividing the water flow into multiple water streams, and after the fertilizer is discharged from the through hole of the box body, it can be respectively rotated into different water streams, or rotated into the interval between two adjacent water streams. It should be noted that since the second blade also separates the fertilizer into multiple fertilizer streams, the number of partitions arranged in this embodiment is the same as the number of second blades, which can ensure that the number of fertilizer streams and water streams is the same, thereby further ensuring the accuracy of the water-fertilizer mixing ratio.

[0064] Example 4 On the basis of the above embodiment, the linear displacement component 6 can choose to manually push the first pipe 1 and the second pipe 2 to move up and down relatively. However, since the manual push cannot accurately control the moving distance, this embodiment also provides a specific implementation of the linear displacement component 6, such as Figure 6 As shown, the linear displacement assembly 6 of this embodiment includes a turntable 601, a limit rod 602, and a guide structure. The turntable 601 is arranged above the first pipe fitting 1, and the turntable 601 is mounted on the second pipe fitting 2. The turntable 601 is threadedly connected to the second pipe fitting 2. An annular limit groove is provided at the bottom of the turntable 601. The limit rod 602 is fixedly arranged on the top of the first pipe fitting 1, and the limit rod 602 is slidably connected to the limit groove. The guide structure is arranged between the first pipe fitting 1 and the second pipe fitting 2, and the guiding direction is along the axial direction of the first pipe fitting 1 or the second pipe fitting 2.

[0065] By rotating the turntable 601, since the turntable 601 is threadedly connected to the second pipe 2, the turntable 601 converts the rotation into up and down movement. When in use, when the first pipe 1 is fixed, the turntable 601 is rotated, and the second pipe 2 moves up and down. When the second pipe 2 is fixed up and down, the turntable 601 is rotated, and the first pipe 1 moves up and down. In order to facilitate the up and down movement of the first pipe 1 or the second pipe 2, the inlet and outlet of the first pipe 1 and the second pipe 2 are connected to the external pipe through a hose or a telescopic bellows, thereby improving the flexibility of operation.

[0066] The guide structure includes a slide groove provided on the outer wall of the second pipe member 2 , a guide block is arranged in the slide groove, and the guide block is fixedly connected to the first pipe member 1 .

[0067] In order to ensure sealing, sealing rings are provided at the connection between the first pipe fitting 1 and the second pipe fitting 2 .

[0068] Working principle of this embodiment When the planting equipment provided by the present embodiment is in use, before irrigation, different ratios are determined according to the fertilizers and crops. When the water-fertilizer ratio needs to be adjusted, the turntable is manually rotated. Since the turntable is threadedly connected to the second pipe fitting, the turntable moves up and down along the second pipe fitting when the turntable rotates. The limit rod moves in the annular limit groove when the turntable rotates, and the limit rod drives the first pipe fitting to move up and down, thereby realizing relative movement between the first pipe fitting and the second pipe fitting, adjusting the water flow inside the first pipe fitting, and then adjusting the water-fertilizer ratio.

[0069] The present invention arranges a second pipe fitting inside the first pipe fitting, the first pipe fitting is used for conveying water, and the second pipe fitting is used for conveying fertilizer. When in use, water and fertilizer are introduced at the same time, and the outlet of the first pipe fitting is connected to the inlet of the irrigation water pipe, so that water can be conveyed and fertilizer can be added at the same time, and there is no need to add an additional water reservoir and then carry out the process of mixing water and fertilizer in the water reservoir in advance, and it can supply in real time according to the actual amount, which is more water-saving and fertilizer-saving; and a linear displacement component is arranged between the first pipe fitting and the second pipe fitting, and the linear displacement component is used to drive the first pipe fitting and the second pipe fitting to move relative to each other. When the first pipe fitting moves, the channel size between the first pipe fitting and the second pipe fitting can be adjusted through the mutual cooperation between the conical surface and the baffle, thereby adjusting the water inlet, and different water flow rates can be adjusted according to the needs of different fertilizers, thereby adjusting the water-fertilizer ratio, and further improving the accuracy of the water-fertilizer blending ratio.

[0070] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
