Description

Technical Field

[0001] This utility model relates to the technical field of integrated water and fertilizer equipment, and in particular to an integrated water and fertilizer equipment for planting olive trees in mountainous areas. Background Technology

[0002] Mountain olive trees are evergreen economic tree species adapted to sloping environments. They are drought-resistant and tolerant of poor soil, and their deep root system can stabilize the soil and prevent slippage. Their fruits can be pressed to extract high-quality olive oil. However, due to the challenges of steep slopes, poor soil, and difficult water and fertilizer management in mountain planting, it is necessary to use integrated water and fertilizer machines to achieve precise control.

[0003] The integrated water and fertilizer machine consists of a water source, water pump, filtration system, fertilization device, control hub, water pipeline and irrigator. When in use, the fertilizer is first prepared into a mother liquor and injected into the fertilization device. The water pump is started to pump water. After the water flows through the filter, it is drawn into the fertilizer solution in proportion by the fertilization device and mixed. Then it is transported to the field through the pipeline and precisely applied to the roots of the crops by the irrigator.

[0004] In existing fertigation equipment, the common practice is to inject solid or liquid fertilizers into a mixing tank together with water for dissolution and dilution. However, this method has significant drawbacks in practical applications: after the fertilizer is injected into the mixing tank, due to physical sedimentation characteristics, a considerable portion of the fertilizer particles or high-concentration solutions will quickly settle and accumulate at the bottom of the tank, making it difficult to achieve timely and sufficient uniform dispersion under conventional stirring or water flow. This sedimentation phenomenon directly leads to a severe uneven distribution of fertilizer solution concentration within the tank, with the upper layer solution having lower fertilizer efficiency. The direct consequence is that during field irrigation and fertilization operations, the effective fertilizer concentration in the irrigation solution output from the mixing tank is far lower than the expected set value, failing to meet the needs of precise crop fertilization. To solve this concentration problem, operators are often forced to perform additional topdressing operations during or after irrigation, significantly increasing the complexity and labor intensity of manual intervention. Utility Model Content

[0005] The purpose of this invention is to solve the problem of uneven fertilizer solution concentration distribution caused by physical sedimentation of fertilizer in the mixing tank in the prior art, and to propose an integrated water and fertilizer equipment for planting olive trees in mountainous areas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water and fertilizer integrated device for planting olive trees in mountainous areas includes a tank for mixing fertilizer. The tank is provided with a feed inlet, a liquid inlet pipe, and a liquid outlet pipe. It also includes a conveying pipe fixedly installed on the tank. The conveying pipe has through holes arranged in a ring. A spiral blade is rotatably installed inside the conveying pipe. The outer end face of the spiral blade contacts the conveying pipe, and the tip of the spiral blade extends to the bottom of the through hole. A liquid transition zone is formed above the spiral blade. When the spiral blade rotates, the liquid in the tank is drawn into or discharged from the conveying pipe.

[0008] To facilitate stirring of the mixture in the tank, preferably, a drive shaft is rotatably installed inside the tank, a scraper is fixedly installed on the drive shaft, the free end of the scraper extends toward the inner wall of the tank, and a stirring plate is fixedly installed on the scraper. When the drive shaft rotates, the scraper and the stirring plate rotate and stir the mixture in the tank.

[0009] To facilitate scraping and lifting of the fertilizer, preferably, the cross-section of the scraper is trapezoidal, and an anti-stick pad is attached to the surface of the scraper.

[0010] To facilitate the flow of fertilizer and liquid mixture to the perimeter of the delivery pipe, preferably, the bottom of the tank is truncated cone-shaped, and the scraper is attached to the bottom of the tank.

[0011] To avoid swirling of the mixture, preferably, baffles are arranged in a ring inside the tank, and the baffles are installed perpendicular to the inner wall of the tank.

[0012] To facilitate the operation of the drive shaft, preferably, a drive motor is fixedly installed on the top of the tank, and the drive motor is fixedly installed to the drive shaft via a coupling.

[0013] Compared with the prior art, this utility model provides an integrated water and fertilizer system for planting olive trees in mountainous areas, which has the following beneficial effects:

[0014] 1. This integrated water and fertilizer system for olive cultivation in mountainous areas uses a conveying pipe in conjunction with spiral blades. On one hand, it transports fertilizer and high-concentration fertilizer solution that have settled at the bottom of the tank upwards through the spiral blades, and then discharges them through the through-holes to a higher area within the tank. This allows the high-concentration fertilizer and solution to mix with the solution above the tank, improving the mixing effect and effectively preventing uneven distribution of fertilizer solution concentration. On the other hand, when the spiral blades reverse, a certain negative pressure is created in the liquid transition zone, drawing liquid near the through-holes into the conveying pipe, which then discharges it through the bottom of the pipe. This achieves a backflushing effect, flushing out any residual fertilizer in the spiral blades and conveying pipe, and also flushing up fertilizer that has settled at the bottom of the tank, preventing fertilizer from accumulating for a long time and causing uneven distribution of fertilizer solution concentration within the tank.

[0015] 2. This integrated water and fertilizer equipment for planting olive trees in mountainous areas uses a scraper and a mixing plate in combination. On the one hand, when the drive shaft rotates, it scrapes up some of the fertilizer that has settled to the bottom of the tank, preventing the fertilizer from settling at the bottom of the tank for a long time, which would cause the concentration of the mixed liquid in the tank to stratify and become uneven. On the other hand, when the scraper and a mixing plate rotate, they can push the fertilizer closer to the conveying pipe, so that the spiral blades can easily transport the fertilizer and high-concentration fertilizer solution to the upper part of the liquid in the tank, thus avoiding the problem of uneven fertilizer concentration in the tank.

[0016] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model uses a conveying pipe and spiral blades to transport the fertilizer and high-concentration fertilizer solution that have settled at the bottom of the tank to the upper part of the liquid in the tank, thereby improving the mixing effect and effectively avoiding the problem of uneven fertilizer concentration in the mixed liquid in the tank due to fertilizer sedimentation and high fertilizer solution concentration at the bottom of the tank.

[0024] Reference Figures 1-4 A water and fertilizer integrated device for planting olive trees in mountainous areas includes a tank 1 for mixing fertilizer. The tank 1 is equipped with a feed inlet, a liquid inlet pipe, and a drain pipe, with the feed inlet and liquid inlet pipe installed on the top of the tank 1 and symmetrically distributed. The drain pipe is installed on the side of the bottom of the tank 1. A drive motor 8 is fixedly installed on the top of the tank 1. The drive motor 8 in this application is a BLDC-57BL series brushless DC motor. The drive motor 8 is fixedly mounted with a drive shaft 7 via a coupling. The device also includes: A conveying pipe 2 is fixedly installed on the tank body 1, and a reserved space is provided between the bottom of the conveying pipe 2 and the bottom of the tank body 1. The reserved space in this application is 8cm. The 8cm reserved space facilitates the entry or exit of fertilizer and high-concentration fertilizer solution into or out of the conveying pipe 2. The conveying pipe 2 has through holes 21 arranged in a ring. A spiral blade 3 is rotatably installed inside the conveying pipe 2, and the spiral blade 3 is fixedly installed with the drive shaft 7. The outer end face of the spiral blade 3 is in contact with the conveying pipe 2, and the top of the spiral blade 3 extends to the bottom of the through hole 21. A liquid transition zone is formed above the spiral blade 3. When the spiral blade 3 rotates, the liquid in the tank 1 is drawn into or discharged from the conveying pipe 2. When the spiral blade 3 rotates counterclockwise, it draws the fertilizer and high-concentration fertilizer solution from the bottom of the tank 1 into the conveying pipe 2. The continuous operation of the spiral blade 3 increases the pressure in the liquid transition zone, thereby discharging the fertilizer and high-concentration fertilizer solution through the through-hole 21 to a higher position in the mixture within the tank 1. This avoids the problem of fertilizer settling at the bottom of the tank 1, leading to uneven fertilizer concentration in the mixture within the tank 1, and effectively improves... The clockwise rotation of the spiral blades 3 increases the uniformity of the mixture in the tank 1. Conversely, the clockwise rotation of the spiral blades 3 creates negative pressure in the liquid transition zone, drawing the mixture from the upper part of the tank 1 into the conveying pipe 2 through the through hole 21, and then discharging it through the bottom of the conveying pipe 2. This improves the uniformity of the fertilizer solution and, on the other hand, uses the mixture to backflush the conveying pipe 2 and the spiral blades 3, causing the fertilizer residue in the conveying pipe 2 to flow out and flushing up some of the fertilizer at the bottom of the tank 1, further enhancing the uniformity of the fertilizer concentration in the mixture.

[0025] Specifically, by using the conveying pipe 2 in conjunction with the spiral blades 3, on the one hand, the fertilizer and high-concentration fertilizer solution that have settled to the bottom of the tank 1 can be transported upward through the spiral blades 3, and then discharged to a higher area inside the tank 1 through the through hole 21, so that the high-concentration fertilizer solution and fertilizer can mix with the solution above the tank 1, thereby improving the mixing effect of fertilizer and liquid and effectively avoiding the problem of uneven distribution of fertilizer solution concentration. On the other hand, when the spiral blades 3 reverse, a certain negative pressure is formed in the liquid transition zone, which draws the liquid near the through hole 21 into the conveying pipe 2, and then discharges it through the bottom of the conveying pipe 2. At this time, a backflushing effect is achieved, flushing out the fertilizer remaining in the spiral blades 3 and the conveying pipe 2, and at the same time flushing up the fertilizer that has settled to the bottom of the tank 1, avoiding the long-term accumulation of fertilizer, which would lead to the problem of uneven distribution of fertilizer solution concentration in the tank 1.

[0026] A drive shaft 7 is rotatably installed inside the tank 1. A scraper 4 is fixedly installed on the drive shaft 7. The free end of the scraper 4 extends towards the inner wall of the tank 1. A stirring plate 5 is fixedly installed on the scraper 4. When the drive shaft 7 rotates, the scraper 4 and the stirring plate 5 rotate and agitate the mixture in the tank 1. On the one hand, the scraper 4 scrapes away the precipitated fertilizer from the bottom of the tank 1, preventing fertilizer from accumulating and sticking to the tank 1 for a long time. On the other hand, the stirring plate 5 rotates and agitates the mixture in the tank 1, thereby improving the mixing effect of the liquid and fertilizer, thus avoiding the problem of uneven fertilizer concentration in the mixture in the tank 1.

[0027] Specifically, the scraper 4 and the stirring plate 5 work together to scrape up some of the fertilizer that has settled at the bottom of the tank 1 when the drive shaft 7 rotates, preventing the fertilizer from settling at the bottom of the tank 1 for a long time, which would cause the mixed liquid concentration in the tank 1 to stratify and become uneven. On the other hand, when the scraper 4 and the stirring plate 5 rotate, they can push the fertilizer closer to the conveying pipe 2, so that the spiral blades 3 can transport the fertilizer and high-concentration fertilizer solution to the upper part of the liquid in the tank 1, thereby avoiding the problem of uneven fertilizer solution concentration in the tank 1.

[0028] The cross-section of the scraper 4 is trapezoidal, and an anti-stick pad is pasted on the surface of the scraper 4. The anti-stick pad can reduce the amount of fertilizer sticking to the surface of the scraper 4 during operation, effectively preventing fertilizer from sticking to the scraper 4, thereby reducing the scraping effect of the scraper 4 on the bottom wall of the tank 1.

[0029] The bottom of the tank 1 is shaped like a frustum, and the scraper 4 is attached to the bottom of the tank 1. The bottom of the tank 1 is shaped like a frustum, and the small end of the tank 1 faces downward. The small end of the tank 1 is tilted inward, so that when used with the scraper 4, the fertilizer moves towards the small end and gets closer to the feed pipe 2. This allows the spiral blades 3 to suck the fertilizer into the feed pipe 2 and transport the fertilizer to the upper part of the mixed liquid, thereby improving the mixing effect of the fertilizer and the liquid and improving the uniformity of the fertilizer concentration in the mixed liquid in the tank 1.

[0030] Inside the tank 1, baffles 6 are arranged in a ring and are installed perpendicular to the inner wall of the tank 1. The existing rotating wheel will drive the material to make a circular motion, which will easily form a "vortex" motion. At this time, the material only slides along the tank wall, resulting in low mixing efficiency. The baffles 6 can block the circular motion of the material, change its flow direction, form radial and axial vortices, and enhance the turbulence intensity. At the same time, the baffles 6 can "disperse" the surface vortices, prevent fertilizer particles from agglomerating against the wall due to centrifugal force, further improve the mixing effect of liquid and fertilizer, thereby improving the uniformity of fertilizer concentration and preventing the phenomenon of subsequent manual topdressing.

[0031] In this invention, fertilizer is first poured into tank 1 through the inlet and water is added to tank 1 through the water inlet pipe. Then, the drive motor 8 is started, which drives the drive shaft 7 to rotate. The drive shaft 7 then drives the spiral blades 3 to work. At this time, the spiral blades 3 absorb the fertilizer and high-concentration fertilizer solution at the bottom of tank 1 into the conveying pipe 2 and transport them upwards. Simultaneously, when the fertilizer and high-concentration fertilizer solution move to the liquid transition zone, the continuous operation of the spiral blades 3 and the subsequent entry of fertilizer solution into the liquid transition zone increase the pressure within the zone, thereby discharging the fertilizer solution and fertilizer solution to the upper layer of the mixture in tank 1, thus improving the liquid mixing effect. When the drive motor 8 reverses, the spiral blades 3 follow the reverse rotation of the drive shaft 7, thereby drawing the mixture from the upper layer of tank 1 into the conveying pipe 2, and then discharging it through the bottom of the conveying pipe 2. This achieves a backflushing effect, flushing out any residual fertilizer in the feed pipe 2. Simultaneously, as the liquid flows out of the feed pipe 2, it impacts the fertilizer and high-concentration liquid at the bottom of the tank 1, causing the high-concentration liquid to flow upwards. This enhances the mixing effect between the fertilizer and the liquid in the tank 1. Meanwhile, when the drive shaft 7 operates, the scraper 4 and stirring plate 5 work together. On one hand, they scrape up the fertilizer at the bottom of the tank 1, preventing it from settling and sticking there for extended periods. On the other hand, the stirring plate 5 agitates the liquid in the tank 1, causing the mixture to move in a circular motion. When the mixture collides with the baffle 6, the original regular circular motion is broken, creating radial and axial vortices. This further enhances the mixing effect between the solution and fertilizer, preventing uneven fertilizer concentration in the mixture and avoiding the need for subsequent manual fertilization.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
