Its intelligent core consists of a control system and a sensor system. The control system includes a PLC, a touch screen operation interface, a remote control module, and a cloud platform, etc. The supply part consists of a fertilization system and an irrigation system. After intelligently collecting information, it provides signals to the fertilization and irrigation systems, and controls them to jointly transport water and fertilizer to the drainage system, thereby improving work efficiency.

[0003] Small-sized integrated water and fertilizer equipment can be relocated, which is more flexible for use in small agricultural environments. For example, the patent with the application number CN202021064620.9 provides an intelligent integrated water and fertilizer fertilization equipment, which drives a mixing tank in a vehicle-mounted manner to complete the mixing of water and fertilizer in the mixing tank, and then discharges it outward through a rectangular tank. However, when water and fertilizer are mixed by its paddle in the mixing tank, some fertilizers will coagulate, and the water pressure during transportation is small, and the discharge tank is easily blocked, affecting the discharge. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] An intelligent integrated water and fertilizer fertilization equipment, including a water and fertilizer integrated pipe, a fertilization device, a water application device, a dredging mechanism, a driving assembly, and an intelligent management system. It is characterized in that the water and fertilizer integrated pipe is connected to the fertilization device and the water application device. The dredging mechanism includes a rotary dredger and a displacement dredger. The driving assembly includes an assembly seat fixed at one end of the water and fertilizer integrated pipe and a driving mechanism arranged in the assembly seat. The other end of the water and fertilizer integrated pipe is connected to the drainage system;

[0006] One end of the rotary dredger extends into the water and fertilizer integrated pipe close to the feed port of the fertilization device, and the other end extends into the assembly seat and is connected to the driving mechanism. One end of the displacement dredger enters the water and fertilizer integrated pipe close to the feed port of the water application device, and the other end enters the assembly seat and is connected to the driving mechanism. The driving mechanism is controlled by the intelligent management system, and when driving the rotary dredger to rotate, it drives the displacement dredger to linearly displace relative to the rotary dredger.

[0007] As a further preference, the intelligent management system includes a detection rod connected to the water and fertilizer integrated pipe. The detection rod is downward and is equipped with a humidity sensor. The humidity sensor is inserted into the soil. The driving mechanism further includes a motor fixed on the assembly seat. The operating shaft of the motor is connected to the rotary dredger. The intelligent management system further includes a first solenoid valve installed on the fertilizer application device and the water application device.

[0008] As a further preference, the rotary dredger is composed of a transmission shaft and a screw propeller installed on the transmission shaft. The screw propeller is located inside the water and fertilizer integrated pipe and is close to the feed inlet of the fertilizer application device. The other end of the transmission shaft is connected to the motor. The displacement dredger is slidably fitted inside the water and fertilizer integrated pipe. A push rod is connected to the displacement dredger. The push rod extends into the assembly seat and is equipped with a trigger seat. The driving assembly further includes an eccentric wheel installed on the transmission shaft. The trigger seat contacts the eccentric wheel.

[0009] As a further preference, the displacement dredger is a piston plate slidably fitted inside the water and fertilizer integrated pipe. A through hole is provided in the middle of the displacement dredger. The transmission shaft passes through the through hole. The aperture of the through hole is larger than the shaft diameter of the transmission shaft.

[0010] As a further preference, a guide sleeve is connected between the assembly seat and the water and fertilizer integrated pipe. The push rod passes through the guide sleeve. A spring is sleeved on the push rod. Both ends of the spring elastically abut between the guide sleeve and the trigger seat.

[0011] As a further preference, a guide sleeve is connected between the assembly seat and the water and fertilizer integrated pipe. The push rod passes through the guide sleeve. A spring is sleeved on the push rod. Both ends of the spring elastically abut between the guide sleeve and the trigger seat.

[0012] As a further preference, the fertilizer application device and the water application device are connected to the water and fertilizer integrated pipe through a material pipe. The first solenoid valve is installed on the material pipe. The dredging mechanism further includes a flushing pipe connected between the material pipe and the water and fertilizer integrated pipe. The intelligent management system further includes a second solenoid valve installed on the flushing pipe. A pressure sensor is installed in the material pipe between the water and fertilizer integrated pipe and the fertilizer application device.

[0013] As a further preference, a fixed bracket is installed on the water and fertilizer integrated pipe.

[0014] The beneficial effects of the present invention compared with the prior art are:

[0015] The intelligent management system detects the current state of the soil. When it is known from the detection result that the degree of soil dryness is greater than the set value, it will automatically control the water application device to supply water to the water and fertilizer integrated pipe. When the soil is dry, it often indicates that the nutrient components in the soil are exhausted. Therefore, the fertilization device in the present invention will also supply fertilizer to the water and fertilizer integrated pipe synchronously. At this time, the drive assembly is started, and the rotary dredger and the displacement dredger act respectively in the water and fertilizer integrated pipe driven by the drive assembly. For example, the rotary dredger rotates in the water and fertilizer integrated pipe to fully mix water and fertilizer. At the same time, through the rotary mixing action of the rotary dredger in the water and fertilizer integrated pipe, it is possible to prevent phenomena such as material jamming and blockage in the water and fertilizer integrated pipe; the displacement dredger is arranged on the feeding side of the rotary dredger. When the displacement dredger rotates with the rotary dredger, at this time, it moves linearly relative to the rotary dredger, and a water pressure is formed between the internal displacement dredger and the rotary dredger in the water and fertilizer integrated pipe, which is used to assist the rotary dredger to smoothly discharge the mixed material of water and fertilizer towards the drainage system. The way of discharging with rotary plus water pressure further prevents the water and fertilizer integrated pipe from being blocked and the discharging is smoother. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0024] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.

[0025] In one embodiment, as Figures 1-7 shown:

[0026] This embodiment provides an intelligent integrated water and fertilizer application device, including an integrated water and fertilizer pipe 10, a fertilizer application device 20, a water application device 30, a dredging mechanism 40, a drive assembly 50 and an intelligent management system. The integrated water and fertilizer pipe 10 is connected to the fertilizer application device 20 and the water application device 30. The dredging mechanism 40 includes a rotary dredger 401 and a displacement dredger 402. The drive assembly 50 includes an assembly seat 501 fixed at one end of the integrated water and fertilizer pipe 10 and a drive mechanism 502 arranged in the assembly seat 501. The other end of the integrated water and fertilizer pipe 10 is connected to a drainage system;

[0027] One end of the rotary dredger 401 extends into the integrated water and fertilizer pipe 10 near the feed inlet of the fertilizer application device 20, and the other end extends into the assembly seat 501 and is connected to the drive mechanism 502. One end of the displacement dredger 402 enters the integrated water and fertilizer pipe 10 near the feed inlet of the water application device 30, and the other end enters the assembly seat 501 and is connected to the drive mechanism 502. The drive mechanism 502 is controlled by the intelligent management system, and when driving the rotary dredger 401 to rotate, it drives the displacement dredger 402 to linearly displace relative to the rotary dredger 401.

[0028] For example, when the intelligent management system detects the current state of the soil and learns from the detection result that the degree of soil dryness is greater than the set value, it will automatically control the water application device 30 to supply water to the water and fertilizer integrated pipe 10. When the soil is dry, it often indicates that the nutrient components in the soil are depleted. Therefore, the fertilizer application device 20 in the present invention will also supply fertilizer to the water and fertilizer integrated pipe 10 synchronously. At this time, the drive assembly 50 is started, and the rotary dredger 401 and the displacement dredger 402 act respectively in the water and fertilizer integrated pipe 10 driven by the drive assembly 50. For example, the rotary dredger 401 rotates in the water and fertilizer integrated pipe 10 to fully mix the water and fertilizer. At the same time, through the rotary mixing action of the rotary dredger 401 in the water and fertilizer integrated pipe 10, it is possible to prevent phenomena such as material jamming and blockage in the water and fertilizer integrated pipe 10; the displacement dredger 402 is arranged on the feeding side of the rotary dredger 401. When the displacement dredger 402 rotates along with the rotary dredger 401, it moves linearly relative to the rotary dredger 401 at this time, and a water pressure is formed between the displacement dredger 402 and the rotary dredger 401 in the water and fertilizer integrated pipe 10 to assist the rotary dredger 401 to smoothly discharge the materials after water and fertilizer mixing towards the drainage system. It is well-known that the viscosity of the water and fertilizer mixture is relatively high. This way of discharging by rotating and adding water pressure further prevents the water and fertilizer integrated pipe 10 from being blocked and the discharging is smoother. As Figure 1 , Figure 2 shown, the drainage system is connected to the discharge end of the water and fertilizer integrated pipe 10 and distributes to both sides to achieve the purpose of evenly supplying to the agricultural area. One end of the rotary dredger 401 and the displacement dredger 402 are jointly driven on the same drive mechanism 502, which not only prevents the water and fertilizer integrated pipe 10 from being blocked but also saves losses.

[0029] As Figure 2 , Figure 4 , the intelligent management system includes a detection rod 90 connected to the water and fertilizer integrated pipe 10. The detection rod 90 is downward and is equipped with a humidity sensor. The humidity sensor is inserted into the soil. The drive mechanism 502 also includes a motor fixed on the assembly seat 501. The moving shaft of the motor is connected to the rotary dredger 401. The intelligent management system also includes a first solenoid valve 100 installed on the fertilizer application device 20 and the water application device 30. The bottom end of the detection rod 90 is inserted into the soil with the humidity sensor to detect the soil condition. For example, when the degree of soil dryness reaches the set value of the controller module 9 (existing intelligent control technology, not elaborated), the controller module controls the motor to rotate electrically, drives the rotary dredger 401 to rotate by the motor, and the controller module opens the first solenoid valve 100 to enable the fertilizer application device 20 and the water application device 30 to supply materials to the water and fertilizer integrated pipe 10, realizing intelligent control and saving resources.

[0030] The rotary dredger 401 consists of a transmission shaft 403 and a screw propeller 404 installed on the transmission shaft 403. The screw propeller 404 is located inside the water-fertilizer integrated pipe 10 and close to the feed inlet of the fertilizing device 20. The other end of the transmission shaft 403 is connected to a motor. The displacement dredger 402 is slidably fitted inside the water-fertilizer integrated pipe 10. A push rod 405 is connected to the displacement dredger 402. The push rod 405 extends into the assembly seat 501 and is equipped with a trigger seat 406. The drive assembly 50 further includes an eccentric wheel 503 installed on the transmission shaft 403. The trigger seat 406 contacts the eccentric wheel 503. The motor drives the transmission shaft 403 to rotate, and the transmission shaft 403 drives the screw propeller 404 to rotate, so that the fertilizer entering the water-fertilizer integrated pipe 10 is conveyed towards the drainage system. At the same time, the transmission shaft 403 drives the eccentric wheel 503 to rotate. The eccentric wheel 503 drives the trigger seat 406 to move linearly, and the trigger seat 406 drives the displacement dredger 402 to move linearly relative to the screw propeller 404 frequently. The water application device 30 supplies water to the water-fertilizer integrated pipe 10, and the water enters the screw propeller 404 and mixes with the fertilizer. Using the screw propeller 404 as the mixing component can not only prevent the water-fertilizer integrated pipe 10 from being blocked, but also drive the displacement dredger 402 to move towards the screw propeller 404 coaxially, pressing the water into the screw propeller 404 in an impact manner, so that the water is slowly discharged under the action of the spiral section of the screw propeller 404, extending the mixing time of the fertilizer and water, improving the dissolution efficiency of the water on the fertilizer. The water and fertilizer flow together into the lower drainage system and seep into the soil through the drainage system, improving the fertilization quality. By pressing the water towards the screw propeller 404 through the displacement dredger 402, the water has impact, preventing the fertilizer from adhering to the blade surface of the screw propeller 404 and further preventing blockage, ensuring smooth discharge of the material.

[0031] As Figure 4 , Figure 5 shown, the displacement dredger 402 is a piston plate slidably fitted inside the water-fertilizer integrated pipe 10. A through hole 4021 is opened in the middle of the displacement dredger 402. The transmission shaft 403 passes through the through hole 4021. The diameter of the through hole 4021 is larger than the shaft diameter of the transmission shaft 403 and is equipped with a sliding bearing. Every time the transmission shaft 403 drives the eccentric wheel 503 to rotate one week, it will push the trigger seat 406 once with its eccentric surface. The trigger seat 406 will push the push rod 405 once, and the push rod 405 will push the displacement dredger 402 to move relative to the screw propeller 404 once, applying pressure to the water entering the screw propeller 404 once. The displacement dredger 402 is fitted on the transmission shaft 403 through a sliding bearing, which will not have an obstructive impact on the rotation of the transmission shaft 403.

[0032] To improve the stability of the push rod 405, as Figures 5-7As shown in the figure, a guide sleeve 60 is connected between the assembly seat 501 and the water and fertilizer integrated pipe 10. The push rod 405 passes through and is slidably assembled in the guide sleeve 60. When the push rod 405 drives the displacement dredger 402 to move back and forth, the guide sleeve 60 plays a role in orienting the push rod 405, ensuring the smooth movement of the displacement dredger 402. One end of the transmission shaft 403 that enters the assembly seat 501 is installed on the assembly seat 501 through a sealed bearing. When the displacement dredger 402 moves back and forth, it prevents water from seeping into the assembly seat 501.

[0033] A spring 70 is sleeved on the push rod 405, and both ends of the spring 70 are elastically abutted between the guide sleeve 60 and the trigger seat 406. Each time the trigger seat 406 pushes the push rod 405, the spring 70 will be compressed once. As the eccentric wheel 503 continues to rotate and the pressure on the trigger seat 406 decreases, the spring 70 resumes its original length and the trigger seat 406 resets, dragging the push rod 405 to return in the reverse direction.

[0034] The fertilizing device 20 and the watering device 30 are connected to the water and fertilizer integrated pipe 10 through a material pipe 80. A first solenoid valve 100 is installed on the material pipe 80. The dredging mechanism 40 further includes a flushing pipe 407 connected between the material pipe 80 and the water and fertilizer integrated pipe 10. The intelligent management system further includes a second solenoid valve 110 installed on the flushing pipe 407. A pressure sensor is installed in the material pipe 80 between the water and fertilizer integrated pipe 10 and the fertilizing device 20. The above solution can ensure that the water and fertilizer integrated pipe 10 will not be blocked, and at the same time can ensure that the water and fertilizer are dissolved and then discharged into the soil together. However, since the fertilizer is granular, when the fertilizing device 20 feeds the fertilizer into the water and fertilizer integrated pipe 10 through its material pipe 80, the fertilizer often blocks its material pipe 80. At this time, due to the blockage of the material pipe 80, pressure will be generated in the pipe cavity (detection principle: when the pressure in the monitored pipeline changes, blockage will cause the pressure in the pipe cavity to rise). The pressure sensor in the material pipe 80 detects the signal and feeds the signal back to the controller module. The controller module controls the second solenoid valve 110 to automatically open. When the displacement dredger 402 presses water towards the screw propeller 404, due to the buffering effect of the screw propeller 404, the water in the water and fertilizer integrated pipe 10 will enter the flushing pipe 407 under the pressure of the water, and then rush into the material pipe 80 from the other end of the flushing pipe 407, so that the fertilizer blocked in the material pipe 80 is automatically dissolved, solving the problem of blockage of the material pipe 80 between the fertilizing device 20 and the water and fertilizer integrated pipe 10. After the material pipe 80 is automatically dredged, the pressure in the pipe cavity becomes smaller, and the pressure sensor feeds this signal back to the controller module again. The controller module closes the second solenoid valve 110, and the automatic flushing ends. However, since the material pipe 80 between the watering device 30 and the water and fertilizer integrated pipe 10 transports clean water, it will not be blocked, so there is no need to set a flushing function.

[0035] The integrated water and fertilizer pipe 10 is installed in the use environment through a fixed bracket, or installed on a vehicle-mounted small integrated water and fertilizer fertilization device through a fixed bracket.

[0036] It should be further noted that the intelligent detection of soil by combining various sensors and controllers mentioned in the present invention is a common control technology in the current intelligent agricultural management system.
