Abstract

The application discloses an intelligent water, fertilizer and pesticide integrated automatic control system, and belongs to the technical field of agricultural spraying irrigation. The system comprises a centralized feeding hopper, a first pipeline, a first control switch, a second pipeline, a second control switch, a control assembly and a third box body. The first control switch is installed on the first pipeline, and is positively rotated to increase the flow of the first pipeline. The second control switch is installed on the second pipeline, and is positively rotated to reduce the flow of the second pipeline. The intelligent water, fertilizer and pesticide integrated automatic control system can quickly adjust the proportion of the fertilizer and the clean water through the control assembly to adapt to the water and fertilizer demand of different crops in different growth periods. Since the first control switch and the second control switch are synchronously rotated, the amount of the increased or reduced flow of the first pipeline is the same as that of the reduced or increased flow of the second pipeline, so that the flow entering the centralized feeding hopper is always balanced.

Description

Technical Field

[0001] This invention relates to the field of agricultural spraying irrigation technology, and more specifically, to an intelligent integrated automatic control system for water, fertilizer and pesticide application. Background Technology

[0002] Smart agriculture represents an advanced stage of agricultural production, applying Internet of Things (IoT) technology to traditional agriculture. It utilizes sensors and software to control agricultural production via mobile or computer platforms, making traditional agriculture more "intelligent." Smart irrigation is a crucial component of smart agriculture, offering numerous advantages such as high efficiency in water and fertilizer conservation, labor reduction, and time saving, while promoting high crop yields and quality. Currently, the vigorous promotion and application of smart irrigation technology in my country's agricultural production necessitates precise sensing, control, regulation, and decision-making regarding water and fertilizer management, requiring a systematic and integrated set of technologies.

[0003] The intelligent water and fertilizer integrated machines used in existing smart irrigation technologies usually use a fixed ratio to mix fertilizer and water. However, different crops require different amounts of water and fertilizer at different growth stages.

[0045] Example:

[0046] See Figure 1This invention discloses an intelligent integrated water, fertilizer, and pesticide automatic control system, comprising a housing 180, a mixing channel 110, a centralized feeding hopper 120, a first box 131, a first pipe 132, a first control switch 133, a second box 141, a second pipe 142, a second control switch 143, a control component 150, a spraying structure 160, a third box 171, and a first nozzle 172. The first box 131 holds fertilizer, the second box 141 holds clean water, and the third box 171 holds pesticide solution. The first nozzle 172 is mounted on the third box 171 and is used to spray the pesticide solution within the third box 171. The first control switch 133 is mounted on the first pipe 132; rotating the first control switch 133 forward increases the flow rate of the first pipe 132. The second control switch 143 is mounted on the second pipe 142; rotating the second control switch 143 forward decreases the flow rate of the second pipe 142. The control component 150 can drive the first control switch 133 and the second control switch 143 to rotate synchronously in the same direction. When the first control switch 133 and the second control switch 143 rotate in the same direction, one of them controls the flow rate to increase, while the other controls the flow rate to decrease, thereby making proportional adjustments to change the concentration of the fertilizer solution.

[0047] The first nozzle 172 employs the principle of a sprayer to spray the pesticide solution, mainly utilizing controlled suction to turn the pesticide solution into a mist, which is then evenly sprayed onto the plants. A compressed air device is installed inside the third housing 171, and the first nozzle 172 is connected to this compressed air device via a thin tube, allowing the pesticide solution to be sprayed out from the first nozzle in a mist form.

[0048] The intelligent water, fertilizer and pesticide integrated automatic control system disclosed in this embodiment can quickly adjust the ratio of fertilizer and clean water through the control component 150 to adapt to the water and fertilizer requirements of different crops at different growth stages. At the same time, since the first control switch 133 and the second control switch 143 rotate synchronously, the amount by which the flow rate of the first pipe 132 increases or decreases is the same as the amount by which the flow rate of the second pipe 142 decreases or increases, so as to ensure that the flow rate entering the centralized feed hopper 120 always remains balanced.

[0049] The housing 180 serves as the overall support for the intelligent integrated water, fertilizer, and pesticide automatic control system disclosed in this embodiment. All components of the intelligent integrated water, fertilizer, and pesticide automatic control system can be mounted on the housing 180. Furthermore, the housing 180 can be installed in different locations as needed. If the housing 180 is installed in the field, the intelligent integrated water, fertilizer, and pesticide automatic control system can be used as a fixed spraying device; if the housing 180 is installed on a tractor or other mobile equipment, the intelligent integrated water, fertilizer, and pesticide automatic control system can be used as a mobile spraying device.

[0050] An opening is provided at the top of the housing 180, and a through hole and an outlet are provided at the bottom of the housing 180.

[0051] Both the mixing channel 110 and the centralized feed hopper 120 are installed inside the housing 180. The centralized feed hopper 120 is installed at the top of the housing 180, and its inlet is connected to the opening at the top of the housing 180. The mixing channel 110 is spiral-shaped, with its top connected to the outlet of the centralized feed inlet and its bottom connected to the outlet at the bottom of the housing 180.

[0052] An agitator 181 is provided at the connection between the centralized feed hopper 120 and the mixing channel 110. The axis of the agitator 181 is arranged along the height direction of the housing 180. The agitator 181 does not need to be equipped with a motor. When water flows through the agitator 181, the agitator 181 will rotate on its own under the impact force of the water flow, thereby causing the liquid entering the mixing channel 110 to mix with each other.

[0053] To ensure a more uniform mixing of water and fertilizer, multiple mixing fans 181 can be installed inside the mixing pipe. These mixing fans 181 are spaced apart along the length of the mixing pipe, and the axis of each mixing fan 181 coincides with the axis of the spiral mixing channel 110.

[0054] The spraying structure 160 is installed at the bottom of the housing 180. The spraying structure 160 includes a fertilizer solution tank 161 and a second nozzle 162. The fertilizer solution tank 161 includes a peripheral wall and a bottom wall. The peripheral wall of the fertilizer solution tank 161 is connected to the housing 180 and surrounds the through-hole and outlet at the bottom of the housing 180. The bottom wall, the peripheral wall, and the bottom of the housing 180 form a cavity for holding the mixed fertilizer solution. The second nozzle 162 is installed on the bottom wall and communicates with the cavity of the fertilizer solution tank 161. The fertilizer solution accumulates in the fertilizer solution tank 161, and pressure is generated by the liquid level difference. At this time, the fertilizer solution in the fertilizer solution tank 161 can be sprayed out using the second nozzle 162.

[0055] In this embodiment, the fertilizer solution is sprayed from the second nozzle 162 primarily by the pressure difference between the heights of the fertilizer solution. This method may result in a short spraying distance when the amount of fertilizer solution is low. To avoid this, a water pipe can be installed at the bottom of the fertilizer solution tank 161. One end of the water pipe is connected to the fertilizer solution tank 161, and a pressure boosting valve is installed at the connection point. The other end of the water pipe is closed. The water pipe is wound around the bottom of the fertilizer solution tank 161, and multiple second nozzles 162 are spaced apart on the water pipe. The pressure boosting valve increases the pressure of the fertilizer solution in the water pipe, thereby increasing the pressure of the fertilizer solution in the second nozzles 162, thus ensuring that the fertilizer solution can be sprayed a sufficient distance.

[0056] In this embodiment, a connecting shaft 182 is provided on the housing 180. One end of the connecting shaft 182 is connected to the stirring fan 181, and the other end of the connecting shaft 182 extends out of the housing 180 after passing through a through hole at the bottom of the housing 180. The end of the connecting shaft 182 extending out of the housing 180 is connected to the bottom wall of the fertilizer tank 161, so that when the stirring fan 181 rotates, the connecting shaft 182 and the bottom wall of the fertilizer tank 161 can rotate synchronously. The rotation of the bottom wall of the fertilizer tank 161 can drive the second nozzle 162 to rotate, so that the water and fertilizer are sprayed more evenly.

[0057] The first housing 131 and the second housing 141 are both installed on the top of the housing 180, and the first housing 131 and the second housing 141 are spaced apart. The first housing 131 is connected to the housing 180 through a first pipe 132, and the end of the first pipe 132 opposite to the first housing 131 is connected to the centralized feed hopper 120. A first control switch 133 is installed on the first pipe 132. The first control switch 133 is a rotary switch. When the first control switch 133 is rotated in the forward direction, the flow rate of the first pipe 132 increases. Conversely, when the first control switch 133 is rotated in the reverse direction, the flow rate of the first pipe 132 decreases. The second housing 141 is connected to the housing 180 through the second pipe 142, and the end of the second pipe 142 away from the second housing 141 is connected to the centralized feed hopper 120. A second control switch 143 is installed on the second pipe 142. The second control switch 143 is a rotary switch. When the second control switch 143 is rotated in the forward direction, the flow rate of the second pipe 142 decreases. Conversely, when the second control switch 143 is rotated in the reverse direction, the flow rate of the second pipe 142 increases.

[0058] See Figure 3 In this embodiment, clockwise direction is considered positive, and counterclockwise direction is considered negative.

[0059] The control assembly 150 includes a first control lever 151 and a second control lever 152. The first control lever 151 and the second control lever 152 are driven by a bevel gear to ensure that the rotation axes of the first control lever 151 and the second control lever 152 are perpendicular to each other. The two ends of the second control lever 152 are respectively connected to the first control switch 133 and the second control switch 143 so that the first control switch 133 and the second control switch 143 rotate synchronously.

[0060] See Figure 4 When the first control lever 151 rotates in the first direction, it drives the second control lever 152 to rotate in the forward direction. Simultaneously, the second control lever 152 drives the first control switch 133 and the second control switch 143 to rotate in the forward direction. During this process, the flow rate in the first pipe 132 increases, while the flow rate in the second pipe 142 decreases. This means that at the same time, the amount of fertilizer entering the centralized feed hopper 120 increases, while the amount of clean water entering the centralized feed hopper 120 decreases, resulting in an increased concentration of fertilizer and water. Conversely, when the first control lever 151 rotates in the second direction, it drives the second control lever 152 to rotate in the reverse direction. Simultaneously, the second control lever 152 drives the first control switch 133 and the second control switch 143 to rotate in the reverse direction. During this process, the flow rate in the first pipe 132 decreases, while the flow rate in the second pipe 142 increases. This means that at the same time, the amount of fertilizer entering the centralized feed hopper 120 decreases, while the amount of clean water entering the centralized feed hopper 120 increases, resulting in a decreased concentration of fertilizer and water.

[0061] When field watering is required, the first control lever 151 can be rotated in the second direction until the first control switch 133 opens the first pipe 132 to its maximum. At this time, the second control switch 143 can completely close the second pipe 142. At this time, the water entering the centralized feed hopper 120 is all clean water, and watering can be carried out. When fertilizer irrigation is required, the first control lever 151 can be rotated in the first direction at a certain angle. At this time, the first control switch 133 reduces the water output of the first pipe 132, and the second control switch 143 allows the second pipe 142 to output a certain amount of fertilizer. The fertilizer and clean water are mixed in the centralized feed hopper, and then pass through the mixing channel 110 to form a uniformly mixed fertilizer solution. At this time, the fertilizer solution can be sprayed into the field using the second nozzle 162.

[0062] The intelligent water, fertilizer and pesticide integrated automatic control system disclosed in this embodiment can perform watering, fertilizer preparation and spraying independently. In addition, it can also spray pesticide using the third box 171 and the first nozzle 172, thereby realizing the integrated operation of clean water, fertilizer and pesticide.

[0063] In some embodiments of this example, a first switch 134 is also installed on the first pipe 132. The first switch 134 is used to directly control the opening and closing of the first pipe 132, and it is also a rotary switch. When the first switch 134 rotates in the forward direction, the first pipe 132 is closed; when the first switch 134 rotates in the reverse direction, the first pipe 132 is open, allowing fertilizer to enter the centralized feed hopper 120 along the first pipe 132. A second switch 144 is also installed on the second pipe 142. The second switch 144 is used to directly control the opening and closing of the second pipe 142, and it is also a rotary switch. When the second switch 144 rotates in the reverse direction, the second pipe 142 is closed; when the second switch 144 rotates in the forward direction, the second pipe 142 is open, allowing fertilizer to enter the centralized feed hopper 120 along the second pipe 142.

[0064] The control assembly 150 further includes a first control tube 153, a second control tube 154, and a third control tube 155. The first control tube 153 is sleeved outside the first control lever 151, while the second control tube 154 and the third control tube 155 are both sleeved outside the second control lever 152, and are located on opposite sides of the first control tube 153. The second control tube 154 and the third control tube 155 are respectively connected to the first control tube 153 via bevel gears. The second control tube 154 is connected to the first switch 134, and the third control tube 155 is connected to the second switch 144.

[0065] See Figure 2 , Figure 3 as well as Figure 5 When the first control tube 153 rotates in the first direction, it drives the second control tube 154 to rotate in the forward direction and simultaneously drives the third control tube 155 to rotate in the reverse direction. During this process, the second control tube 154 drives the first switch 134 to rotate in the forward direction, while the third control tube 155 drives the second switch 144 to rotate in the reverse direction. This closes both the first pipe 132 and the second pipe 142, and the intelligent water, fertilizer, and pesticide integrated automatic control system stops working. When operation is required, simply rotate the first control tube 153 in the second direction. This causes the second control tube 154 to rotate the first switch 134 in the reverse direction, and the third control tube 155 to rotate the second switch 144 in the forward direction, opening both the first pipe 132 and the second pipe 142.

[0066] Based on the above structure, it can be seen that the intelligent water, fertilizer and pesticide integrated automatic control system disclosed in this embodiment can open and close the first pipe 132 and the second pipe 142 by rotating the first control tube 153, and can change the flow rate of the first pipe 132 and the second pipe 142 by rotating the first control rod 151, thereby changing the concentration of water and fertilizer.

[0067] Furthermore, in this embodiment, a control ring 156 is also installed between the first control lever 151 and the first control tube 153. By using the restriction of the control ring 156, only one of the first control lever 151 and the first control tube 153 can rotate at the same time, thereby avoiding mutual interference between the rotation of the first control lever 151 and the first control tube 153.

[0068] A connecting rod 1561 is provided on the control ring 156, and the connecting rod 1561 extends out of the first control tube 153 in a direction away from the third control tube 155. The connecting rod 1561 is used to control the position of the control ring 156 so that the control ring 156 can restrict either the first control rod 151 or the first control tube 153.

[0069] See Figure 4 An annular notch is provided on the outer wall of the first control rod 151, and the diameter of the first annular notch 1511 gradually decreases along the direction from the first control rod 151 toward the second control rod 152.

[0070] See Figure 5 A second annular notch 1531 is provided on the inner wall of the first control tube 153. The diameter of the second annular notch 1531 gradually decreases along the direction from the first control tube 153 toward the second control rod 152, and the second annular notch 1531 is located below the first annular notch 1511.

[0071] See Figure 2 , Figure 6 and Figure 7 The inner diameter of the first end of the control ring 156 is smaller than the inner diameter of its second end, and the inner diameter of the first end of the control ring 156 is smaller than or equal to the outer diameter of the first control rod 151. The first end of the control ring 156 is engaged within the first annular notch 1511. The outer diameter of the second end of the control ring 156 is larger than the outer diameter of its first end, and the outer diameter of the second end of the control ring 156 is larger than or equal to the inner diameter of the first control tube 153. The second end of the control ring 156 is engaged within the second annular notch 1531.

[0072] Since both the first annular notch 1511 and the second annular notch 1531 have a gradually changing shape, the control ring 156 can abut against the first control lever 151 or the first control tube 153 respectively when moving up and down. (See reference...) Figure 2 and Figure 4 Because the upper diameter of the first annular notch 1511 is relatively large, when the control ring 156 moves upward, the first end of the control ring 156 will engage with the first control lever 151. At this time, the first control lever 151 is restricted, preventing it from rotating. (See also...) Figure 2 and Figure 5Because the bottom diameter of the second annular notch 1531 is large, when the control ring 156 moves downward, the second end of the control ring 156 will be engaged with the first control tube 153. At this time, the first control tube 153 is restricted, causing the first control tube 153 to be unable to rotate.

[0073] In a preferred embodiment, a first inclined surface 1562 adapted to the first annular notch 1511 is provided on the inner wall of the first end of the control ring 156, and a second inclined surface 1563 adapted to the second annular notch 1531 is provided on the outer wall of the second end of the control ring 156. By having the first inclined surface 1562 engage with the gradually changing shape of the first annular notch 1511, and by having the second inclined surface 1563 engage with the gradually changing shape of the second annular notch 1531, the connection between the control ring 156 and the first control rod 151 or the first control tube 153 can be better achieved. In this embodiment, the control ring 156 mainly restricts the first control rod 151 and the first control tube 153 through friction. The first inclined surface 1562 and the second inclined surface 1563 increase the contact area between the control ring 156 and the first control rod 151 and the first control tube 153, thereby forming a more stable control.

[0074] Specifically, when using the intelligent water, fertilizer and pesticide integrated automatic control system, if it is necessary to shut down, first lift the first control lever 151. At this time, the second end of the control ring 156 is separated from the first control tube 153, while its first end is engaged with the first control lever 151. At this time, the first control lever 151 cannot rotate, while the first control tube 153 can rotate freely. By controlling the first control tube 153 to rotate in the first direction, both the first pipe 132 and the second pipe 142 can be shut down.

[0075] When the intelligent water, fertilizer and pesticide integrated automatic control system needs to be restarted, simply rotate the first control tube 153 in the second direction.

[0076] When adjusting the concentration of water and fertilizer in the intelligent integrated water, fertilizer, and pesticide automatic control system, first press down the control ring 156. At this time, the first end of the control ring 156 separates from the first control rod 151, while its second end is engaged with the first control tube 153. The first control tube 153 cannot rotate, while the first control rod 151 can rotate freely. When the first control rod 151 rotates in the first direction, the concentration of water and fertilizer increases; when the first control rod 151 rotates in the second direction, the concentration of water and fertilizer decreases.

[0077] See Figure 7 In this embodiment, the counterclockwise direction in the figure is taken as the first direction, and the clockwise direction in the figure is taken as the second direction.

[0078] It should be noted that the intelligent water, fertilizer and pesticide integrated automatic control system disclosed in this embodiment can be controlled by a fully automatic control system. A motor is connected to the first control tube 153 and the second control rod 152 respectively. The control ring 156 is then connected to the cylinder through the connecting rod 1561. Both the motor and the cylinder can be controlled by the background control system, thereby realizing remote fully automatic control.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
