Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural irrigation, and specifically relates to smart agricultural quantitative irrigation equipment. Background Art

[0002] Smart agriculture is a new agricultural production method that uses modern information technology and intelligent equipment to visualize, digitally design, and manage agricultural production objects, environments, and processes. During the crop irrigation process, flow meters are used in the pumping pipelines to monitor the amount of water delivered each time, achieving quantitative irrigation.

[0003] The electronic flowmeter can be connected to the computer in the machine room via a network cable. Alternatively, a communication terminal can be installed to connect to the computer via a wireless network, allowing staff to remotely control the amount of irrigation. This allows one person to control the irrigation volume for multiple fields, eliminating the need for frequent field visits and improving irrigation management efficiency.

[0004] During agricultural irrigation, in order to achieve refined irrigation, a pipeline is generally divided into several branches, and an electronic flow meter and a solenoid valve are installed on each branch as a branch node to control the on and off of the branch. However, the branch node often protrudes laterally from the branch pipe to which it belongs, and there are no protective measures on the outside of the branch node. It is easy for the branch pipe to scrape and collide with crops when moving, which is not conducive to improving the safety of quantitative irrigation at each branch node. Utility Model Content

[0005] The purpose of the utility model is to provide a smart agricultural quantitative irrigation equipment, which adopts protective measures to cover the control components from the outside to resist scratches or collisions during subsequent movement, which is conducive to improving the safety of quantitative irrigation at each branch node.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A smart agricultural quantitative irrigation device includes an irrigation pump, wherein the output end of the irrigation pump is connected to a plurality of hoses and a plurality of three-way joints arranged alternately, wherein two opposite interfaces of the three-way joint are respectively connected to one end of an adjacent hose, and the third interface is connected to a control component, and the top of the three-way joint is connected to a double helix tube through the control component, wherein both ends of the double helix tube are downward and the two ends are connected to a hanging part, and the double helix tube surrounds the control component along the top and two adjacent hanging parts along both sides for protection, and the outer side of the double helix tube is connected to a plurality of water outlet pipes at intervals along the spiral line. After the irrigation pump is started, the control component is turned on so that each The outlet pipes of the branch nodes sprinkle water circumferentially, and the water sprinkling heights of each outlet pipe are different. The water outlet layers are clear and can cover a wider area. The horizontal angles between the outlet pipes are adjustable to minimize dead angles in sprinkling. During this process, the control component monitors the water sprinkling volume in real time. When the set volume is reached, the branch node is closed, and the water flow between the corresponding double helix pipes is stopped, while the water flow between the hoses is maintained until all branch nodes are closed, and the irrigation pump is controlled to stop. At the same time, the double helix pipes and the drooping parts are used as protective measures to cover the control component from the outside to resist scratches or collisions during subsequent movement, which is conducive to improving the safety of quantitative irrigation at each branch node.

[0008] As a preferred solution, the control component includes an electronic flow meter and a solenoid valve that are interconnected, wherein the water inlet of the electronic flow meter is connected to the third interface of the three-way connector, the water outlet is connected to the water inlet end of the solenoid valve, and the water outlet end of the solenoid valve is connected to the two ends of the double helix tube. During irrigation, the internal flow channels of the electronic flow meter and the solenoid valve remain unobstructed, and are used to flow through the branch node until the set amount is reached, and then the solenoid valve is controlled to close by the control main board to close the branch node.

[0009] As a preferred solution, the third interface of the three-way connector is also connected to an alloy straight tube for supporting an electronic flow meter and a solenoid valve. A battery box electrically connected to the electronic flow meter and the solenoid valve is fixed on one side of the alloy straight tube, which can be powered independently, saving the operation of integrated wiring in large-scale pepper fields.

[0010] As a preferred solution, a wireless communication module electrically connected to the battery box is fixed on the outside of the alloy straight tube.

[0011] As a preferred solution, a floor mop is fixed on the lower surface of the three-way joint. The floor mop is perpendicular to the double helix tube and uses the ground to stably support and straighten the branch node. Its bottom area is large enough to be stably grounded and not easy to tilt. It can cooperate with the double helix tube to further reduce the exposed area of ​​the control component and enhance protective measures.

[0012] As a preferred solution, an indicator light electrically connected to the battery box is fixed in the middle of the upper end face of the double helix tube. The indicator light can be turned on under conditions of low visibility to emit red light to indicate each branch node, making it convenient to avoid branch nodes during farmland operations.

[0013] As a preferred solution, the central axis of the double helix tube coincides with the central axis of the alloy straight tube, so that the center of gravity of the branch node falls on the alloy straight tube. Especially when the ground at the branch node is muddy, the branch node can still remain vertical and is not easy to fall over.

[0014] The technical effects achieved by this utility model are:

[0015] After the irrigation pump of the present invention is started, the control component is turned on to make the water outlet pipe of each branch node sprinkle water circumferentially, and the water sprinkling heights of each water outlet pipe are different, the water outlet layers are clear, and a wider area can be covered.

It can cooperate with the double helix tube to further reduce the exposed area of ​​the control component and enhance the protection measures. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] To facilitate the expansion and production of smart agriculture, we continue to promote the use of automated irrigation equipment. This is especially true for the cultivation of crops such as peppers. Timed and quantitative irrigation of seedlings is essential, while manual watering is inefficient and difficult to achieve uniform watering.

[0026] like Figure 1-Figure 5 As shown, a smart agricultural quantitative irrigation equipment is controlled by a computer at an irrigation station, including an irrigation pump 1. The irrigation pump 1 can be a BJZ037 model jet self-priming pump with a head of 36m, a power of 0.37kw, and a rated flow rate of 1.5m³ / h. The output end of the irrigation pump 1 is connected to multiple hoses 2 and multiple three-way joints 3 arranged alternately. The two opposite interfaces of the three-way joints 3 are respectively connected to one end of the adjacent hoses 2, and the third interface is connected to a control component. The top of the three-way joints 3 is connected to a double helix tube 4 through the control component. Both ends of the double helix tube 4 face downward and are connected to a hanging part 5. The hanging part 5 and the double helix tube 4 are bent into an integrated form. The double helix tube 4 surrounds the control component along the top and along both sides of the two adjacent hanging parts 5 for protection. The outer side of the double helix tube 4 is connected to multiple water outlet pipes 6 at intervals along the spiral line.

[0027] After the pepper seedlings are planted, an irrigation pipe is laid every 8 rows. An irrigation pump 1 is used to centrally deliver water at the irrigation station. The irrigation pipe is divided into several branch nodes. The branch nodes are connected by hoses 2. One end of the last hose 2 is closed. After the irrigation pump 1 is started, water is pumped into each irrigation pipe, and the control component is turned on. The water is diverted using the three-way joint 3 and sprayed along the control component and the double spiral tube 4 to each outlet pipe 6. The outlet pipe 6 of each branch node sprays water circumferentially, and the watering height of each outlet pipe 6 is different, the water outlet layer is clear, and it can cover a larger area. The horizontal angle between the outlet pipes 6 is adjustable over a wide area. In this embodiment, it is preferably 10° to minimize blind spots in watering. During this process, the control component monitors the watering amount in real time. When the set amount is reached, the branch node is closed, and the corresponding double helix pipe 4 stops supplying water, while the water flow between the hoses 2 is maintained until all branch nodes are closed, and then the irrigation pump 1 is controlled to shut down. At the same time, the double helix pipe 4 and the drooping portion 5 are used as protective measures to cover the control component from the outside to resist scratches or collisions during subsequent movement, which is beneficial to improving the safety of quantitative irrigation at each branch node.

[0028] Refer to the attached Figure 2 、 Figure 4 and Figure 5 The control component includes an electronic flowmeter 7 and a solenoid valve 8 that are interconnected. The electronic flowmeter 7 and the solenoid valve 8 are both connected to the control main board by signal. The control main board can use a Mitsubishi single-chip microcomputer. Among them, the electronic flowmeter 7 can use a DN40 model integrated intelligent electromagnetic flowmeter with an operating voltage of 24VDC and a pressure resistance of 1Mpa. The solenoid valve 8 can use a 2W-400-40 model normally closed electromagnetic copper valve with an operating voltage of 24VDC. The water inlet of the electronic flowmeter 7 is connected to the third interface of the three-way connector 3, and the water outlet is connected to the water inlet end of the solenoid valve 8. The water outlet end of the solenoid valve 8 is connected to the two ports of the double helix tube 4. During irrigation, the internal flow channels of the electronic flowmeter 7 and the solenoid valve 8 remain unobstructed, and are used to flow through the branch node until the set amount is reached. Then the solenoid valve 8 is closed by the control main board to close the branch node.

[0029] Refer to the attached Figure 2 、 Figure 4 and Figure 5 The third interface of the three-way connector 3 is also connected to an alloy straight tube 9 for supporting the electronic flow meter 7 and the solenoid valve 8. A battery box 10 electrically connected to the electronic flow meter 7 and the solenoid valve 8 is fixed on one side of the alloy straight tube 9. The battery box 10 has two built-in 24V rechargeable lithium batteries, which can be powered independently, saving the operation of integrated wiring in large-scale pepper fields.

[0030] Refer to the attached Figure 2 、 Figure 4 and Figure 5A wireless communication module 11 electrically connected to the battery box 10 is fixed on the outside of the alloy straight tube 9. The wireless communication module 11 can be a LoRa module with an RS485 interface and a transmission distance of ≥1.2km. It is used to control the communication of the mainboard, realize remote transmission and reception of control signals, and control the electronic flow meter 7 and the solenoid valve 8.

[0031] Refer to the attached Figure 2 and Figure 4 A floor mop 12 is fixed on the lower surface of the tee joint 3. The floor mop 12 is perpendicular to the double helix tube 4 and can stably support and straighten the branch node. Its bottom area is large enough to be stably grounded and not easy to tilt. It can cooperate with the double helix tube 4 to further reduce the exposed area of ​​the control component and enhance the protective measures.

[0032] Refer to the attached Figure 2 and Figure 3 An indicator light 13 electrically connected to the battery box 10 is fixed in the middle of the upper end surface of the double helix tube 4. The indicator light 13 can be turned on under conditions of low visibility to emit red light to indicate each branch node, making it convenient to avoid branch nodes during farmland operations.

[0033] Refer to the attached Figure 2 and Figure 4 The central axis of the double helix tube 4 coincides with the central axis of the alloy straight tube 9, so that the center of gravity of the branch node falls on the alloy straight tube 9. Especially when the ground at the branch node is muddy, the branch node can still maintain a vertical state and is not easy to fall over.

[0034] The working principle of the present invention is as follows: after the irrigation pump 1 is started, water is pumped to each irrigation pipe, and the control component is turned on, the water is diverted by the three-way joint 3, and sprayed along the control component and the double helix tube 4 to each water outlet pipe 6, so that the water outlet pipe 6 of each branch node sprays water circumferentially, and the water spraying heights of each water outlet pipe 6 are different, the water outlet layers are clear, and a wider area can be covered.

[0035] During this process, the control component monitors the watering amount in real time. When the set amount is reached, the branch node is closed, the water supply to the corresponding double helix pipe 4 is stopped, and the water flow between the hoses 2 is kept unobstructed until all branch nodes are closed, and then the irrigation pump 1 is controlled to shut down.

[0036] At the same time, the double helix tube 4 and the hanging part 5 are used as protective measures to cover the control component from the outside to resist scratches or collisions during subsequent movement, which is beneficial to improving the safety of quantitative irrigation at each branch node.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
