Description

Technical Field

[0001] This invention relates to the technical field of water and fertilizer machines, and more particularly to an intelligent water and fertilizer machine. Background Technology

[0002] In my country, fertilizer utilization is not high in agricultural irrigation. The traditional method is to spread fertilizer directly on the land, but only a small portion of the fertilizer is actually absorbed by crops, while most of it is washed into rivers by rainwater, resulting in low fertilizer utilization.

[0003] Integrated water and fertilizer management combines irrigation and fertilization, precisely measuring water and fertilizer dosages. Based on soil moisture content and crop type, it differentiates the required amounts of water and fertilizer at different growth stages, then mixes them in a proportional manner to achieve balanced fertilization. As a novel technology integrating fertilization and irrigation, integrated water and fertilizer management systems play a significant role not only in farmland but also in greenhouse farming, forestry, and soilless cultivation.

[0004] Chinese utility model patent CN202021796410.9 describes a water-fertilizer machine with fertilizer mixing function. Through the set control box, second motor and output impeller, it can quickly and accurately mix multiple fertilizers evenly together. However, the device can only mix fertilizers quantitatively and cannot accurately know the exact weight of the fertilizer mixture. This is not conducive to controlling the water-fertilizer ratio with high precision and is difficult to apply in practice. Summary of the Invention

[0005] Therefore, there is a need for an intelligent water and fertilizer machine to solve the problem of inaccurate fertilizer metering during water and fertilizer mixing.

[0006] To achieve the above objectives, the inventor provides an intelligent water and fertilizer machine, comprising: a frame, a storage tank, and a mixing tank. The frame is provided with a material discharge chute. The storage tank is movable on the frame via a moving mechanism, allowing it to move back and forth between a material discharge position and a non-material discharge position. When the storage tank is in the material discharge position, the discharge port of the storage tank can discharge material into the material discharge chute. The mixing tank is located below the material discharge chute to receive the material. The mixing tank is connected to a water source.

[0007] The mixing tank is equipped with a mixing assembly, a metering assembly, and a telescopic component. The metering assembly is located above the mixing assembly and includes an elastic element and a metering disc. The upper surface of the metering disc has a conical structure with its cone apex facing upwards. The edge of the metering disc is adapted to the inner wall of the mixing tank. The lower end of the metering disc is connected to the inside of the mixing tank through the elastic element. The lower end of the metering assembly is connected to the inside of the mixing tank through the telescopic component. The tank wall of the mixing tank is provided with a first contact area and a boss area. The boss area is an outwardly protruding discharge space.

[0008] When the metering disc is above the first contact area, the fertilizer on the metering disc will not leave the metering disc. When the metering disc is below the first contact area, the fertilizer on the metering disc can slide from the boss area to the bottom of the metering disc for mixing.

[0009] A sensor is provided on the first contact area. The sensor is electrically connected to a microcontroller. The microcontroller is electrically connected to the moving mechanism and the telescopic component. The microcontroller is used to control the telescopic component to extend and retract and the moving mechanism to move.

[0010] Furthermore, the intelligent water and fertilizer machine also includes a second contact area, which is a strip-shaped structure evenly distributed on the wall of the mixing tank, extending downward from the upper end of the boss area.

[0011] Furthermore, the moving mechanism includes a moving motor and a track. The track is located above the frame, and the bottom of the storage bin is adapted to the track. The fixed end of the moving motor is fixed to the frame, and the output end of the moving motor is connected to the storage bin. The moving motor is used to push the storage bin to move along the track.

[0012] Furthermore, multiple desiccant boxes are detachably installed on the inner wall of the storage hopper.

[0013] Furthermore, multiple storage bin vibration motors are installed on the side wall of the storage bin.

[0014] Furthermore, the bottom plate of the storage hopper is configured as a funnel-shaped structure, and the height of the discharge port of the storage hopper is lower than the height of other positions at the bottom of the storage hopper.

[0015] Furthermore, the intelligent water and fertilizer machine also includes a water and fertilizer filtration mechanism, which is connected to the outlet of the mixing tank. The water and fertilizer filtration mechanism includes a filter box and a multi-stage filter plate set inside the filter box. The direction of the filter plate is not parallel to the water inlet direction of the water and fertilizer filtration mechanism.

[0016] Furthermore, the first contact area is a protrusion structure evenly distributed on the wall of the mixing tank, and the thickness value of the protrusion ranges from 0.5 to 1 cm.

[0017] Furthermore, the measuring disc is a hollow shell structure, and a measuring disc vibration motor is installed inside the measuring disc.

[0018] Furthermore, a sealing ring is fitted around the edge of the measuring disc, and the measuring disc engages with the mixing tank through the sealing ring.

[0019] Unlike existing technologies, the above technical solution has the following advantages: In this application, after the metering disc contacts the sensor on the first contact area, the sensor, controlled by the microcontroller, moves the storage bucket away, stopping the material from falling into the mixing tank. Then, the microcontroller activates the telescopic component, causing the metering disc to move downwards. The edge of the metering disc is pressed downwards past the first contact area to reach the boss area, at which point the telescopic component stops working, and the fertilizer on the metering disc is discharged into the boss area. This application, through the metering component installed inside the mixing tank, does not rely on the discharge time; it stops discharging only after the metering component has measured the predetermined amount of fertilizer, thus enabling high-precision control of the water-fertilizer ratio.

[0055] Please see Figures 1 to 5This embodiment of an intelligent water and fertilizer machine includes: a frame 1, a storage tank 2, and a mixing tank 3. The frame 1 is provided with a material discharge trough 11. The storage tank 2 is moved on the frame 1 by a moving mechanism so that the storage tank 2 can move back and forth between the material discharge position and the non-material discharge position. When the storage tank 2 is in the material discharge position, the discharge port 23 of the storage tank can discharge material into the material discharge trough 11. The mixing tank 3 is arranged below the material discharge trough 11 to receive the material. The mixing tank 3 is connected to a water source.

[0056] The mixing tank 3 is equipped with a mixing component, a metering component, and a telescopic component 5. The metering component is located above the mixing component and includes an elastic component 31 and a metering disc 32. The upper surface of the metering disc 32 is a conical structure with its cone apex facing upward. The edge of the metering disc 32 is adapted to the inner wall of the mixing tank 3. The lower end of the metering disc 32 is connected to the mixing tank 3 through the elastic component 31. The lower end of the metering component is connected to the mixing tank 3 through the telescopic component 5. The tank wall of the mixing tank 3 is provided with a first contact area 34 and a boss area 35. The boss area 35 is an outwardly protruding discharge space.

[0057] When the metering plate 32 is above the first contact area 34, the fertilizer on the metering plate 32 will not leave the metering plate 32. When the metering plate 32 is below the first contact area 34, the fertilizer on the metering plate 32 can slide from the boss area 35 to the bottom of the metering plate 32 for stirring.

[0058] A sensor is provided on the first contact area 34. The sensor is electrically connected to a microcontroller. The microcontroller is electrically connected to the moving mechanism and the telescopic member 5. The microcontroller is used to control the telescopic member 5 to extend and retract and the moving mechanism to move.

[0059] The frame 1 includes multiple legs and a platform 13 connected above the legs. The platform 13 of the frame 1 can hold the storage tank 2 and the mixing tank 3 at the upper and lower positions respectively. When the discharge chute 12 is connected to the discharge port 23 of the storage tank, the fertilizer in the discharge chute 11 can fall into the mixing tank 3 under its own gravity. Preferably, the size of the discharge port 23 of the storage tank is smaller than the size of the discharge chute 11 on the frame 1.

[0060] The frame 1 has a material discharge trough 11, which is a through-hole structure formed on the platform 13 of the frame 1. The cross-section of the through-hole structure can be circular, elliptical, square, pentagonal, or other shapes. In some preferred embodiments, the upper end of the material discharge trough 11 is provided with an upwardly extending receiving channel, which is adapted to the discharge port 23 of the storage tank. The lower end of the material discharge trough 11 is provided with a downwardly extending discharge channel, which extends into the mixing tank 3 to avoid the influence of environmental factors such as wind and humidity on the fertilizer. In a more preferred embodiment, a storage tank 2 cover plate is provided above the storage tank 2, and a storage tank 2 inlet is formed on the storage tank 2 cover plate. The discharge channel of the material discharge trough 11 is adapted to the storage tank 2 inlet.

[0061] The mixing assembly specifically consists of a mixing motor 36 and a mixing blade 37. The fixed end of the mixing motor 36 is located at the bottom of the mixing tank 3, and the output end of the mixing motor 36 is connected to the mixing blade 37. The mixing blade 37 works with the mixing motor 36 to stir the water-fertilizer mixture in the mixing tank 3, so that the fertilizer is fully dissolved in the water.

[0062] The elastic element 31 of the metering component is preferably a spring. The weight of fertilizer on the metering disc 32 is applied to the elastic element 31, causing the elastic element 31 to undergo elastic deformation. The weight of fertilizer applied to the metering disc 32 corresponds proportionally to the compression of the elastic element 31. For example, if the weight of fertilizer on the metering disc 32 is 5KG, the compression of the spring is 2CM. As the weight of fertilizer on the metering disc 32 increases, the compression of the spring increases. As the weight of fertilizer on the metering disc 32 increases, the metering disc 32 gradually moves downward. When the metering disc 32 reaches the first contact area 34, the weight of fertilizer on the metering disc 32 reaches the preset value. At this time, the moving mechanism is controlled to move the storage tank 2, so that the storage tank 2 stops dropping material into the mixing tank 3, thereby controlling a high fertilizer weighing accuracy.

[0063] The upper surface of the metering disc 32 has a conical structure with its cone apex facing upwards, which allows the fertilizer on the metering disc 32 to fall along the inclined conical surface of the metering disc 32 during the feeding process, which helps to feed the fertilizer quickly.

[0064] The raised area 35 of the mixing tank 3 refers to the material dropping area that extends outward from the tank wall of the mixing tank 3. The mixing tank 3 has a cylindrical structure, and the raised area 35 is an annular structure with a diameter larger than the diameter of the mixing tank 3 body. The lower surface of the raised area 35 is inclined from top to bottom toward the inside of the mixing tank 3, so that the fertilizer on the metering plate 32 can be dropped quickly after passing through the raised area 35.

[0065] The telescopic component 5 is specifically a cylinder. A connecting through hole is provided on the stirring blade. The lower end of the telescopic component 5 passes through the connecting through hole and is connected to the bottom of the stirring tank. The stirring blade will not interfere with the telescopic component 5 during rotation. The upper end of the telescopic component 5 is connected to the bottom of the metering plate.

[0066] When the intelligent water and fertilizer machine is working, the moving mechanism moves the storage tank 2 so that the discharge port 23 of the storage tank corresponds to the discharge chute 11 on the frame 1. The fertilizer in the storage tank 2 falls from the storage tank 2 into the metering plate 32 of the mixing tank 3 by its own weight. Since the edge of the metering plate 32 is adapted to the inner wall of the mixing tank 3, the fertilizer will not fall from the edge of the metering plate 32 before the preset weight of the fertilizer is reached. As the weight of the fertilizer gradually increases, the elastic element 31 is squeezed and the metering plate 32 moves downward until the metering plate 32 contacts the sensor on the first contact area 34. During the descent of the metering plate 32, the compression of the elastic element 31 corresponds to the weight of the fertilizer on the metering plate 32. After the metering disc 32 contacts the sensor on the first contact area 34, the sensor, controlled by the microcontroller, moves the storage tank 2 away, stopping the material from the storage tank 2 into the mixing tank 3. Then, the microcontroller activates the telescopic component 5, causing the metering disc 32 to move downwards. The edge of the metering disc 32 is pressed downwards through the first contact area 34 to reach the boss area 35. The telescopic component 5 stops working, and the fertilizer on the metering disc 32 is discharged into the boss area 35. After the discharge is complete, the microcontroller controls the telescopic component 5 to rise upwards, allowing the metering disc 32 to smoothly pass through the first contact area 34. The telescopic component 5 stops working, and then the elastic force of the reliable elastic component 31 restores the disc to its initial state.

[0067] The sensor may specifically be a push button switch, touch switch, contact sensor switch, infrared sensor switch, or distance sensor, etc., located on the first contact area 34.

[0068] In this application, metering is performed using a metering component installed inside the mixing tank 3. Compared to a structure that relies directly on the dispensing time for metering, its advantages are particularly evident in the following ways: A structure that relies directly on the dispensing time requires a continuous supply of fertilizer in the storage tank 2. If the fertilizer in the storage tank 2 is depleted and not replenished in time, it will affect the water-fertilizer ratio. Furthermore, many fertilizers have water-absorbing properties and are prone to clumping. During long-term dispensing, the outlet 23 of the storage tank, being close to the mixing tank 3, tends to be quite humid, easily leading to clumping. This results in the total amount of fertilizer passing through the outlet within a certain period being less than a predetermined value. If metering were still based on the dispensing time, the total amount dispensed would be lower than the estimated amount, and the amount of fertilizer in the water-fertilizer mixture would be lower than the estimated amount. However, in this application, the metering component installed inside the mixing tank 3 does not rely on the dispensing time. Dispensing only stops after the metering component has measured the predetermined amount of fertilizer, thus enabling more precise control of the water-fertilizer ratio.

[0069] In some embodiments, the intelligent water and fertilizer machine further includes a second contact area 38, which is a strip-shaped structure evenly distributed on the wall of the mixing tank 3. The second contact area 38 extends downward from the upper end of the protrusion area 35. Since the second contact area 38 extends downward from the upper end of the protrusion area 35, that is, the second contact area 38 consists of multiple strip-shaped structures evenly distributed within the protrusion area 35, the function of the second contact area 38 is to provide a larger material drop space for the fertilizer on the metering plate 32. In a preferred embodiment, the strip-shaped structure is provided with a protruding structure on the side facing the center of the mixing tank 3, and the thickness value of the protrusion ranges from 0.5 to 1 cm.

[0070] In some embodiments, multiple desiccant boxes 21 are detachably mounted on the inner wall of the storage hopper 2. Detachable connection refers to a simple and quick connection method, generally requiring only an insertion or knob action. The desiccant boxes 21 can be fixed to the inner wall of the storage hopper 2 via hook or snap-fit ​​structures. The desiccant boxes 21 can be replaced as needed. The desiccant inside the desiccant boxes 21 absorbs moisture from the storage hopper 2, maintaining a dry environment in the storage hopper 2.

[0071] In some embodiments, a plurality of storage bin vibration motors 22 are provided on the side wall of the storage bin 2. The storage bin vibration motors 22 can work continuously, which can effectively prevent fertilizer from clumping and accumulating inside the storage bin 2.

[0072] In some embodiments, the moving mechanism includes a moving motor and a track 14. The track 14 is disposed above the frame 1, specifically above the platform 13 of the frame 1. The bottom of the storage bin 2 is adapted to the track 14. The fixed end of the moving motor is fixed to the frame 1, and the output end of the moving motor is connected to the storage bin 2. The moving motor is used to push the storage bin 2 to move along the track 14. Specifically, two tracks 14 are provided and are parallel to each other. The bottom of the storage bin 2 is provided with two grooves adapted to the tracks 14.

[0073] In some embodiments, the bottom plate of the storage hopper 2 is configured as a funnel-shaped structure, and the height of the discharge port 23 of the storage hopper 2 is lower than the height of other parts of the bottom of the storage hopper 2. This has the advantage of accelerating the discharge speed of fertilizer within the storage hopper 2.

[0074] In some embodiments, the intelligent fertigation machine further includes a fertigation filtration mechanism 4, which is connected to the outlet of the mixing tank 3. The fertigation filtration mechanism 4 includes a filter box and multi-stage filter plates 41 disposed within the filter box. The direction of the filter plates 41 is not parallel to the water inlet direction of the fertigation filtration mechanism 4. The outlet of the fertigation filtration mechanism 4 is connected to the location to be irrigated via a delivery pipeline. Large undissolved fertilizer particles or silt that may be present in the fertigation mixture flowing out of the mixing tank 3 can be intercepted by the fertigation filtration mechanism 4, thereby preventing silt and large undissolved fertilizer particles from clogging the delivery pipeline. Preferably, the direction of the filter plates 41 is perpendicular to the water inlet direction of the fertigation filtration mechanism 4. Preferably, there are two filter plates 41, with the filter plate 41 closer to the water inlet direction of the fertigation filtration mechanism 4 having a larger mesh size than the filter plate 41 further away from the fertigation filtration mechanism 4.

[0075] In some embodiments, the first contact area 34 is a protrusion structure evenly distributed on the wall of the mixing tank 3, and the thickness value of the protrusion ranges from 0.5 to 1 cm.

[0076] In some embodiments, a sealing ring is fitted around the edge of the measuring disc 32, and the measuring disc 32 engages with the mixing tank 3 via the sealing ring. The sealing ring is made of silicone or rubber. The sealing ring is tightly fitted around the edge of the measuring disc 32.

[0077] In some embodiments, the metering disc 32 is a hollow shell structure, and a metering disc vibration motor 321 is installed inside the metering disc 32. When the metering disc 32 is discharging material in the protrusion area 35, the metering disc vibration motor 321 can be activated to vibrate the metering disc 32, which can accelerate the discharging of fertilizer on the metering disc 32. Even if the metering disc 32 is pushed against the first contact area 34 by the elastic force of the elastic member 31, since the first contact area 34 is a protrusion structure evenly distributed on the wall of the mixing tank 3, a certain material discharge gap is still maintained between the upper surface of the metering disc 32 and the first contact area 34, and the fertilizer can fall smoothly through the material discharge gap.

[0078] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
