Description

TECHNICAL FIELD

[0001] The present application relates to the field of irrigation, in particular to an intelligent irrigation system and method for water and fertilizer integration. BACKGROUND

[0002] The irrigation system plays a vital role in modern agriculture and garden management. Irrigation not only replenishes soil moisture, but also improves plant growth conditions. Through irrigation, the air humidity and temperature of the garden can be adjusted to create a suitable growth environment for plants. At the same time, irrigation can also wash the dust on the plants, so that the leaves remain clean, thereby improving the efficiency of photosynthesis. Through reasonable irrigation, the yield and quality of crops can be significantly improved.

[0003] In the traditional irrigation method, there are mainly two methods of drip irrigation and sprinkling irrigation. Compared with drip irrigation, sprinkling irrigation has much higher operation efficiency and can more efficiently supplement water to crops to ensure the normal growth of crops. In the existing irrigation method, fertilizer and water are often mixed and then sprayed to supplement the required nutrients for crops. The existing method of applying liquid fertilizer is usually through artificial or mechanical spraying. However, the amount of pesticide sprayed at one time is very limited, or a spraying device is used to spray pesticide liquid. However, such a method often needs to prepare a larger space in advance for mixing pesticide liquid and water, which is time-consuming and laborious, and the operation is very complex. At the same time, the height of the existing sprinkling equipment is very limited. In the process of spraying pesticides, a throwing method is often used for sprinkling. When the crop has a certain height and the row spacing is not small, the sprayed pesticide liquid often gathers below the plant leaves. Under the action of gravity, most of it will drip down, making it difficult to accumulate on the leaves, and reducing the speed of fertilizer absorption by the leaves. SUMMARY

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 10 As shown, the present invention provides an intelligent irrigation system for water and fertilizer integration, comprising: A walking support plate 100, wherein rollers for traveling are installed at the four corners of the lower end of the walking support plate 100, and a support rod 101 along the vertical direction is fixedly installed in the middle position of the walking support plate 100; The medicine storage tank 102 is in an elongated shape and is vertically mounted on the support rod 101; A drive motor 103 is fixedly mounted on the middle position of the side of the support rod 101 away from the medicine storage tank 102. The drive shafts on the upper and lower sides of the drive motor 103 are each coaxially fixedly connected to a centrifugal fan 200. The centrifugal fan 200 includes two base plates 201 and a plurality of fan blades 202 uniformly distributed circumferentially between the two base plates 201. The centrifugal fan 200 is rotatably mounted on the support rod 101. A cylindrical shell 300 is sleeved on the outer side of the centrifugal fan 200 and fixedly connected to the support rod 101. An air inlet 301 is provided at one end of the shell 300 facing the support rod 101, and an air outlet 302 is provided at one end of the shell 300 facing away from the support rod 101. The infusion mechanism 400 is two infusion mechanisms 400 , and the two infusion mechanisms 400 are respectively connected to the centrifugal fan 200 from one end thereof away from the drive motor 103 , and the medicine storage tank 102 is in communication with the infusion mechanism 400 .

[0022] In the process of irrigation operation by using the intelligent irrigation system, water flow is injected into the infusion mechanism 400, and when the water flow flows through the position where the medicine storage tank 102 is located, the liquid medicine in the medicine storage tank 102 will enter the infusion mechanism 400 and mix with the water flow in the infusion mechanism 400, and then the water flow carrying the liquid medicine will enter the centrifugal fan 200 through the infusion mechanism 400, (the blade structure of the centrifugal fan 200 adopts the blade structure of the existing air conditioner, and an alloy material is used to improve the strength), the centrifugal fan 200 inhales air from the position of the air inlet 301, and blows air out at the position of the air outlet 302, under the joint action of centrifugal force and air flow, the water flow carrying the liquid medicine will approach the direction of the fan blade 202 of the centrifugal fan 200, the water flow carrying the liquid medicine will collide with the fan blade 202 of the centrifugal fan 200 and will be blown out from the position of the air outlet 302, and the walking support plate 100 carrying the rollers can conveniently transfer the intelligent irrigation system, through the above technical scheme, by setting the medicine storage tank 102 to store liquid medicine, by using the infusion mechanism 400 to transport water flow and mixing liquid medicine and water flow together, the continuous operation capacity of the device can be obviously improved, and a large space is not needed to mix liquid medicine and water, and the centrifugal fan 200 is used to spray liquid medicine, which can uniformly spray liquid medicine to the leaves of plants at various heights, preventing liquid medicine from being sprayed to the lower end of the leaves, causing liquid medicine to be difficult to stay on the leaves for a long time, and causing poor absorption of liquid fertilizer by the leaves.

[0023] As shown in Figure 1 and Figure 2 , the infusion mechanism 400 includes a liquid medicine inlet pipe 401, a negative suction pipe 402, and an infusion pipe 403, the negative suction pipe 402 is fixedly arranged on the support rod 101, the negative suction cavity 404 is arranged in the negative suction pipe 402, the middle position of the negative suction cavity 404 is elongated, the two end positions of the negative suction cavity 404 are in the shape of a horn opening, the negative suction pipe 402 is fixedly connected with the liquid medicine inlet pipe 401, the negative suction pipe 402 is provided with a liquid medicine inlet groove 405 which is in communication with the middle position of the negative suction cavity 404, the liquid medicine inlet groove 405 is in communication with the liquid medicine inlet pipe 401, and the two ends of the negative suction pipe 402 are respectively connected with the infusion pipe 403.

[0024] It should be noted that water flows into the negative suction pipe 402 through the external water pipe. When the water flows into the negative suction chamber 404, the water body will be compressed when passing through the middle position of the negative suction chamber 404, thereby greatly accelerating the flow speed of the water flow. The faster the fluid is, the smaller its pressure will be. In this way, negative pressure will be generated at the connection position between the medicine liquid inlet groove 405 and the negative suction chamber 404. Under the action of negative pressure, the medicine will enter the negative suction chamber 404 through the medicine liquid inlet pipe 401 and the medicine liquid inlet groove 405, thereby realizing the function of autonomous addition of medicine liquid.

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the infusion mechanism 400 further includes a mixing barrel 406, which includes a barrel shell 407, which is fixedly connected to the centrifugal fan 200, and a spiral stirring impeller 408 is fixedly installed in the middle position of the barrel shell 407.

The mixing barrel 406 further includes a connecting ring 409, which is communicated with the infusion tube 403 and is fixedly mounted on the support rod 101. Figure 3 As shown, the stirring impeller 408 is processed with a plurality of tooth grooves, which can further increase the mixing speed of the liquid medicine in the water.

[0026] It should be noted that when the water carrying the medicine enters the mixing barrel 406 through the infusion tube 403, the centrifugal fan 200 will drive the rotation of the barrel shell 407 during the rotation, and the barrel shell 407 will drive the rotation of the stirring impeller 408 when rotating. The stirring impeller 408 can further mix the medicine and the water flow. At the same time, the stirring impeller 408 can increase the speed of the fluid flow while breaking up the water flow and making it move circumferentially, so that the water flow can contact the fan blades 202 of the centrifugal fan 200 faster.

[0027] like Figures 4 to 8 as well as Figure 11 As shown, the cylindrical shell 407 is provided with a liquid separation chamber 203 on one side located inside the centrifugal fan 200, and the side of the liquid separation chamber 203 is connected to a liquid separation pipe 204 that is communicated with the interior of the liquid separation chamber 203 corresponding to the fan blades 202 of each centrifugal fan 200, and a liquid spreading groove 205 is provided in the fan blades 202 of the centrifugal fan 200 along the vertical direction. The liquid spreading groove 205 is close to the outer side of the fan blades 202 of the centrifugal fan 200 and is communicated with the outside, and the liquid spreading pipe 204 is communicated with the liquid spreading groove 205.

[0028] It should be noted that in the process of rotating the centrifugal fan 200, the water flow enters the separation chamber 203 from the inside of the barrel shell 407, and then the water flow enters the liquid spraying groove 205 in the fan blade 202 of the centrifugal fan 200 through the separation pipe 204, and then the liquid is sprayed along the liquid spraying groove 205. Since the centrifugal fan 200 is in a high-speed rotating state, the liquid is quickly sprayed out. Through the above technical scheme, the spraying distance of the mixed liquid of the water flow and the liquid medicine can be effectively improved.

[0029] As shown in Figures 4 to 8 and Figure 11 The barrel shell 407 is fixedly connected with a liquid spraying chamber 206 at the lower end of the separation chamber 203, the first liquid outlet groove 207 is arranged on the side of the separation chamber 203 corresponding to the position of the separation pipe 204, the separation chamber 203 is divided into a liquid separation chamber 208 at a position close to the outside, the liquid separation chamber 208 is communicated with the separation pipe 204, the second liquid outlet groove 209 is arranged on the lower side of the separation chamber 203 opposite to the liquid spraying chamber 206, the first liquid outlet groove 207 and the second liquid outlet groove 209 are uniformly arranged in four circumferential directions, the liquid separation cover 210 is rotatably connected in the separation chamber 203, the liquid separation cover 210 is rotatably connected in the separation chamber 203, the third liquid outlet groove 211 and the fourth liquid outlet groove 212 are arranged on the side and the bottom of the liquid separation cover 210, respectively, the third liquid outlet groove 211 and the fourth liquid outlet groove 212 correspond to the first liquid outlet groove 207 and the second liquid outlet groove 209, respectively, the third liquid outlet groove 211 and the fourth liquid outlet groove 212 are separated by an included angle of 45 degrees, and the liquid separation cover 210 penetrates the bottom surface of the centrifugal fan 200.

[0030] It should be noted that in the process of using, the liquid separation cover 210 is rotated, the first liquid outlet groove 207 is blocked by the liquid separation cover 210, and the second liquid outlet groove 209 and the fourth liquid outlet groove 212 are coincided, at this time the water flow is sprayed from the lower part of the separation chamber 203, and is collided with the blades of the fan blade 202 under the action of centrifugal force, and is finally taken out and sprayed by the action of air. In this way, the water flow can be broken down more finely and sprayed more uniformly. Rotating the liquid separation cover 210 makes the fourth liquid outlet groove 212 blocked, and the first liquid outlet groove 207 and the third liquid outlet groove 211 are coincided, at this time the water flow containing liquid medicine enters the liquid separation chamber 208, and enters the fan blade 202 of the centrifugal fan 200 through the separation pipe 204. The water flow containing liquid medicine is directly sprayed out by the centrifugal force. In this way, the spraying distance of the liquid medicine can be obviously improved.
