[0002] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. Integrated water and fertilizer technology uses a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water through a controllable pipeline system to supply water and fertilizer. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly, regularly, and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always remains loose and has an appropriate moisture content.

[0003] The invention patent with publication number CN111903347A discloses a water-fertilizer integrated drip irrigation device, which solves the problem that when the existing drip irrigation device is in use, the water flow in the water-fertilizer integrated drip irrigation device is relatively small, resulting in relatively small water pressure affecting the efficiency of irrigation. The device includes a main body, a bottom groove and an inner groove, the base is a conical structure, and the base is installed on the bottom of the slide plate through a spring; the support plate is an arc structure, and the support plate is installed at the bottom of the water pipe; the bottom groove is arranged at the bottom end edge of the main body, and the inner rod inside the bottom groove is arranged at the bottom of the bottom plate, and the vertical rod outside the bottom groove is installed on the side of the main body through a connecting plate; the inner groove is a rectangular structure, and the inner groove is arranged on the inner side of the main body.

[0004] In the above scheme, the water flow is cut off in time during rainy days through the bottom trough, and the pressure is increased through the inner trough when the water flow is less, so that the floating plate pushes the pressure plate to generate water pressure on the water flow, thereby accelerating the speed of drip irrigation. However, it does not take into account that the fertilizer is not completely dissolved in the water, resulting in the water-fertilizer ratio not reaching the expected level, which affects the growth of crops. At the same time, the dissolved fertilizer and impurities suspended in the water will also block the dripper along the pipeline, increasing the maintenance cost. Summary of the invention

[0019] To sum up, when mixing water and fertilizer, fertilizer and water are introduced into the mixing support shell in a certain proportion through the feeding component and the water injection component. After the fertilizer and water are fully introduced, the pressure sensor can detect the pressure data generated by the fertilizer on the filter screen, and convert it into the quality data of the fertilizer through the mixing intelligent controller. Once the driving part is started, it will drive the stirring blade to rotate, and the water-fertilizer ratio is detected by the concentration detection component, and the corresponding ratio data can be obtained. The feeding component, the water injection component and the filtering component are controlled according to the ratio data. After stirring for a certain period of time, when the ratio data still does not reach the standard value, the telescopic part will retract the output end and drive the filter screen to move upward.

DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 6 A water-fertilizer integrated drip irrigation device is shown, including a mixing device 1, the mixing device 1 includes a mixing support shell 101, a driving member 102 is installed at the bottom of the mixing support shell 101, and a stirring blade 103 is installed at the output end of the driving member 102. The driving member 102 drives the stirring blade 103 to rotate to accelerate the dissolution of the fertilizer.

[0035] The mixing support shell 101 is respectively connected to a feed assembly 2, a water injection assembly 3, and a drip irrigation assembly 4. The feed assembly 2 is used to input fertilizer into the mixing support shell 101, the water injection assembly 3 is used to input pure water into the mixing support shell 101, and the drip irrigation assembly 4 is used to output the mixed water and fertilizer.

[0036] A concentration detection component 7 is installed at the bottom of the mixing support shell 101, which is used to detect the concentration of the solution in the mixing support shell 101. A filtering device 8 is installed inside the mixing support shell 101. The filtering device 8 includes a telescopic member 801 fixedly connected to the top of the mixing support shell 101, and a filter screen 802 is fixedly connected to the output end of the telescopic member 801. The filter screen 802 is slidably connected to the inner wall of the mixing support shell 101, and a pressure sensor is provided at the connection between the filter screen 802 and the telescopic device. The filtering device 8 can filter fertilizers and impurities that are not completely dissolved in the water to prevent clogging of the dripper and reduce maintenance costs.

[0037] The mixing support shell 101 is located above the filter 802 and is equipped with a rolling device 5. The rolling device 5 includes a driving mechanism and a rolling mechanism installed at the output end of the driving mechanism. The driving mechanism is installed on the mixing support shell 101. The driving mechanism drives the rolling mechanism to work and is used to crush the block fertilizer that has not been completely dissolved on the filter 802, increase the contact area between the fertilizer and water, increase the dissolution speed and degree of dissolution, and effectively solve the problem of inaccurate water-fertilizer ratio caused by incomplete dissolution of the fertilizer.

[0038] A hybrid intelligent controller 6 is installed on the outer wall of the hybrid support shell 101. The hybrid intelligent controller 6 is provided with a main control module, a command module, and a detection module. The main control module is electrically connected to the command module and the detection module respectively. The command module is electrically connected to the driving member 102 and the driving mechanism respectively. The detection module is electrically connected to the pressure sensor.

[0039] When drip irrigation is required, water and fertilizer are introduced into the mixing support shell 101 through the feeding component 2 and the water injection component 3. The feeding component 2 includes a feeding pipe 202 and a solenoid valve 1 201 installed on the feeding pipe 202. The water injection component 3 includes a water injection pipe 302 and a solenoid valve 2 301 installed on the water injection pipe 302. The instruction module is electrically connected to the solenoid valve 1 201 and the solenoid valve 2 301 respectively. The main control module controls the solenoid valve 1 201 and the solenoid valve 2 301 to open through the instruction module, so that fertilizer and water are respectively introduced into the mixing support shell 101 through the feeding pipe 202 and the water injection pipe 302. The instruction module controls the solenoid valve 1 201 and the solenoid valve 2 301 according to the water-fertilizer ratio (the water-fertilizer ratio in the current state is preset in the main control module) to control the ratio of fertilizer and water introduced into the mixing support shell 101. After the water and fertilizer are introduced, the instruction module controls the solenoid valve 1 201 and the solenoid valve 2 301 to close.

[0040] During the process of passing fertilizer, the fertilizer will fall onto the filter 802. The main control module detects the pressure data output by the pressure sensor installed at the connection between the filter 802 and the output end of the telescopic member 801 through the detection module, converts the pressure data into the fertilizer passing quality data, and records the passing quality data.

[0041] When all the water and fertilizer are passed into the mixing support shell 101, in order to accelerate the dissolution of the fertilizer, the instruction module controls the action of the driving member 102, and the action of the driving member 102 drives the stirring blade 103 to rotate. The rotation of the stirring blade 103 will drive the water in the mixing support shell 101 to increase its flow rate and mix the fertilizer. During the fertilizer mixing process, the main control module obtains the proportion data output by the concentration detection component 7 through the detection module.

[0042] After mixing for a period of time, the ratio data is compared with the specified ratio (the specified ratio in the current state is preset in the main control module). If the difference between the ratio data and the specified ratio is within a certain error range, the drip irrigation component 4 is turned on. The drip irrigation component 4 includes a dripper, which is connected to the mixing support shell 101 through a drip irrigation pipe 402. The drip irrigation pipe 402 is equipped with a solenoid valve 3 401 and a water pump 403. The instruction module is electrically connected to the solenoid valve 3 401 and the water pump 403 respectively. The instruction module controls the solenoid valve 3 401 to open, and then controls the water pump 403 to start, and the water and fertilizer in the mixing support shell 101 are transported to the dripper through the drip irrigation pipe 402 for drip irrigation; if the ratio data is less than the specified ratio, the instruction module controls the telescopic member 801 to retract the output end of the telescopic member 801, driving the filter screen 802 to move upward, and the filter screen 802 removes the undissolved fertilizer in the water. The filter screen 80 2 drives the fertilizer to move until the filter 802 contacts the rolling mechanism, the command module controls the telescopic member 801 to stop moving, fixes the output end position, and the main control module detects the pressure data output by the pressure sensor installed at the connection between the filter 802 and the output end of the telescopic member 801 through the detection module, and compares the pressure data with the rolling pressure (the main control module is preset with the rolling pressure in the current state). If the pressure data is less than the rolling pressure, the command module controls the output end of the telescopic member 801 to retract until the difference between the pressure data and the rolling pressure is within a certain error range, the command module controls the telescopic member 801 to stop moving and maintain the current position; if the pressure data is greater than the rolling pressure, the command module controls the output end of the telescopic member 801 to extend until the difference between the pressure data and the rolling pressure is within a certain error range, the command module controls the telescopic member 801 to stop moving and maintain the current position.

[0043] After the rolling mechanism adjusts the pressure data of the filter 802, the instruction module controls the driving mechanism to drive the rolling mechanism to work. A limiting ring 507 is fixedly connected to the top of the inner wall of the mixing support shell 101. A limiting groove 508 is opened on the limiting ring 507, and the driving mechanism is rotatably connected to the limiting groove 508. The driving mechanism includes a second driving member 501, which is installed on the top outer wall of the hybrid support shell 101. The output end of the second driving member 501 is fixedly connected with a driving gear 502, and the driving gear 502 is meshed with a driven gear 503. The driven gear 503 is fixedly connected with a driving rod 504. The driving rod 504 penetrates the hybrid support shell 101 and is fixedly connected with a driving gear 505. The driving gear 505 is meshed with a transmission gear ring 506. The transmission gear ring 506 is fixedly connected with a rolling mechanism. The transmission gear ring 506 is rotatably connected with the limiting groove 508. The instruction module controls the action of the second driving member 501, and the action of the second driving member 501 drives the driving gear 502 to rotate, and the action of the driving gear 502 drives the driven gear 503 to rotate, and the action of the driven gear 503 drives the driving gear 503 to rotate through the driving rod 504. The gear 505 rotates, and the driving gear 505 rotates to drive the transmission gear ring 506 to move. The transmission gear ring 506 rotates to drive the rolling mechanism to rotate. The rolling mechanism includes a rolling base 509, and the rolling base 509 is fixedly connected to the transmission gear ring 506. A rolling shaft 510 is fixedly connected to the rolling base 509, and a rolling roller 511 is rotatably connected to the rolling shaft 510. The rolling roller 511 is arranged corresponding to the filter 802. There are multiple rolling bases 509, and multiple rolling bases 509 are arranged along the circumference of the transmission gear ring 506. The rolling base 509 rotates with the transmission gear ring 506, driving the rolling shaft 510 to rotate synchronously. The rolling roller 511 contacts the filter 802, and rotates along the axial direction of the rolling shaft 510 as the transmission gear ring 506 rotates, so as to crush the fertilizer filtered out of the filter 802 into small particles.

[0044] When the fertilizer is crushed, the pressure data of the crushing mechanism and the filter 802 will change. When the pressure data is compared with the crushing pressure (the crushing pressure in the current state is preset in the main control module), when the difference between the pressure data and the crushing pressure is within a certain error range, the instruction module controls the driving part 2 501 to stop the action, and then controls the output end of the telescopic part 801 to extend, driving the filter 802 to move downward, and putting the filter 802 back into the water to allow the crushed fertilizer to continue to dissolve.

[0045] At this time, the water-fertilizer ratio will be detected again, and the ratio data will be compared with the specified ratio. If the difference between the ratio data and the specified data is within a certain error range, the drip irrigation component 4 will be opened for drip irrigation; if the ratio data is less than the specified ratio, the feeding component 2 will be opened, and the fertilizer will be introduced into the mixing support shell 101, and the pressure sensor will measure the input quality data and record it. After the difference between the ratio data and the specified data is within a certain error range, the drip irrigation component 4 will be opened for drip irrigation; if the ratio data is greater than the specified ratio, the water injection component 3 will be opened to dilute the water and fertilizer. After the difference between the ratio data and the specified data is within a certain error range, the drip irrigation component 4 will be opened for drip irrigation.

[0046] When the difference between the proportional data and the specified data is within a certain error range and drip irrigation is ready, the instruction module will control the telescopic member 801 to retract and drive the filter 802 to move upward. At this time, the main control module detects the pressure data output by the pressure sensor installed at the connection between the filter 802 and the output end of the telescopic member 801 through the detection module, and converts the pressure data into the remaining mass data of the fertilizer, and the remaining mass data, and the input mass data is processed with the input mass data to obtain the mass of the consumed fertilizer. When mixing next time, new fertilizer will be introduced according to the mass of the consumed fertilizer and the remaining mass.

[0047] After the water and fertilizer are evenly mixed, the water and fertilizer will be output through the drip irrigation assembly 4 for drip irrigation. The drip irrigation assembly 4 includes a dripper, which is connected to the mixing support shell 101 through a drip irrigation pipe 402. The drip irrigation pipe 402 is equipped with a solenoid valve three 401 and a water pump 403. The instruction module is electrically connected to the solenoid valve three 401 and the water pump 403 respectively. The instruction module controls the solenoid valve three 401 to open, and then controls the water pump 403 to start, so that the water and fertilizer in the mixing support shell 101 are transported to the dripper through the drip irrigation pipe 402 to achieve drip irrigation.

[0048] The second implementation method:

[0049] Figure 1-Figure 5 and Figure 7-Figure 8A water-fertilizer integrated drip irrigation device is shown. Different from the first embodiment, a concentration detection component 7 is added to the bottom of the mixing support shell 101, and the concentration detection component 7 is connected through the bottom of the mixing support shell 101. The concentration detection component 7 includes a detection support shell 701, a measuring rod 703 is inserted on the detection support shell 701, and a float 702 placed in the inner cavity of the mixing support shell 101 is fixedly connected to the top of the measuring rod 703, and a piston 705 is fixedly connected to the bottom of the measuring rod 703. The piston 705 is slidably connected to the inner wall of the detection support shell 701, and an air pressure sensor 704 is installed at the top of the inner wall of the detection support shell 701, and an early warning button 706 is installed at the bottom of the inner wall of the detection support shell 701. The detection module is electrically connected to the air pressure sensor 704 and the early warning button 706 respectively. When mixing water and fertilizer, the water-fertilizer ratio may be different from the preset ratio due to the inability to completely dissolve the fertilizer, and the effect of drip irrigation will be affected.

[0050] In the process of mixing water and fertilizer, the proportion of dissolved fertilizer in water is different, and the buoyancy generated for the float 702 will also be different. Therefore, when the water level of the float 702 in the mixing support shell 101 is constant, the position of the float 702 floating in the water will change with the proportion of dissolved fertilizer in the water. The more dissolved fertilizer there is, the greater the buoyancy of the water, and the greater the buoyancy applied to the float 702. The greater the degree of compression of the gas in the detection support shell 701, the higher the air pressure. The main control module collects the air pressure data measured by the air pressure sensor 704 through the detection module, and converts the air pressure data into proportional data, and then compares the proportional data with the specified proportion. When the proportional data is higher than the specified proportion, the instruction module controls the output end of the telescopic member 801 to retract, driving the filter 802 to move upward to scoop out the fertilizer that is not completely dissolved in the water. out, prevent the fertilizer from continuing to dissolve, further improve the proportion data, control the solenoid valve 2 301 to open, and pass water into the mixing support shell 101 to reduce the proportion data. When the proportion data is within a certain range of the specified proportion error range, the instruction module controls the solenoid valve 2 301 to close, and opens the solenoid valve 3 401 and the water pump 403 for drip irrigation; when the proportion data is lower than the specified proportion, the instruction module controls the solenoid valve 1 201 to open, and passes fertilizer into the mixing support shell 101 to improve the proportion data. After part of the fertilizer is passed, the instruction module controls the solenoid valve 1 201 to close, so that the fertilizer and water are fully mixed. When the proportion data is within a certain range of the specified proportion error range, the instruction module controls the telescopic member 801 to retract, removes the fertilizer that is not completely dissolved in the water, and then opens the solenoid valve 3 401 and the water pump 403 for drip irrigation.

[0051] During the drip irrigation process, the float 702 will drop with the remaining water and fertilizer in the mixing support shell 101. When the water and fertilizer are dripped, the float 702 is no longer affected by the buoyancy of the water and fertilizer, and will move downward under the action of gravity. When it moves down to the bottom of the detection support shell 701, it will trigger the early warning button 706. The main control module detects the status data of the early warning button 706 through the detection module. When it is detected to be triggered, it can send the drip irrigation completion information to the operator.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
