Description

Technical Field

[0001] This utility model belongs to the field of farmland irrigation technology, specifically relating to a smart irrigation nozzle for farmland that can automatically adjust the water volume. Background Technology

[0002] Sprinkler irrigation is a method of irrigation that sprays water under pressure into the air, breaking it into small droplets or forming a mist that falls onto plants and the ground. A sprinkler head is a special component of a sprinkler system.

[0003] Currently, existing farmland irrigation sprinklers typically spray water outward through holes in the outer wall of the sprinkler head. However, the amount of water sprayed by traditional farmland irrigation sprinklers is often fixed. If you want to adjust the amount of water sprayed, you usually need to replace the sprinkler head with one of different diameters. However, this method is very inconvenient to operate and is not conducive to farmland irrigation. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent irrigation sprinkler head for farmland that can automatically adjust the water volume. This invention aims to solve the problem that existing farmland irrigation sprinklers typically spray water outward through holes on the outer wall of the sprinkler head. However, the water volume sprayed by traditional farmland irrigation sprinklers is often fixed. If the water volume is to be adjusted, it is usually necessary to replace the sprinkler head with one of different diameters.

[0011] As a preferred embodiment of the intelligent irrigation nozzle for farmland with automatically adjustable water volume according to this utility model, the connecting block is embedded inside the groove.

[0012] As a preferred embodiment of the intelligent irrigation nozzle for farmland with automatically adjustable water volume according to this utility model, the slot and one end of the pin are adapted to each other in size, and one end of the pin is circular.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By inserting a detection probe into the soil and then using a soil moisture sensor to collect soil moisture information, the controller then operates an electric telescopic rod to raise and lower the adjusting cap based on the soil moisture. When the first water outlet overlaps with the nozzle hole, the water sprayed will be sprayed according to the diameter of the first water outlet.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a smart irrigation nozzle for farmland that can automatically adjust water volume, including a base 1, a connecting pipe 2 installed on the top of the base 1, a nozzle 3 connected to the top of the connecting pipe 2, a controller 4 installed on the top of the base 1, and a soil moisture sensor 5 provided on the outer wall of the connecting pipe 2.

[0025] Among them, controller 4 is a programmable logic controller of model S7-200, soil moisture sensor 5 is a soil moisture detector of model ym-01, and detection probe 6 is model FDS-100.

[0026] The soil moisture sensor 5 is connected to a detection probe 6 at its terminal, a water inlet pipe 7 is connected to the outer wall of the connecting pipe 2, a fixing frame 8 is connected to the top of the connecting pipe 2, an electric telescopic rod 9 is installed on the top of the fixing frame 8, an adjusting cap 10 is connected to the output end of the electric telescopic rod 9, and a plurality of first water outlet holes 11 and second water outlet holes 12 are distributed in a ring on the outer wall of the adjusting cap 10.

[0027] Existing farmland irrigation sprinklers are used to spray water evenly and accurately from the holes of the sprinkler head 3 to every corner of the farmland. However, when in use, the sprinkler head 3 needs to be connected to the water source through a pipe, and the water source is generally transported by a pump.

[0028] Preferably, the first water outlet 11 is located at the bottom of the second water outlet 12, the adjusting cap 10 is located inside the nozzle 3, the outer wall of the adjusting cap 10 is fitted with a sealing ring 13, and the sealing ring 13 is located between the adjusting cap 10 and the nozzle 3.

[0029] In practical use, the detection probe 6 is inserted into the soil, and the soil moisture sensor 5 collects soil moisture information. Then, based on the soil moisture, the controller 4 controls the electric telescopic rod 9 to drive the adjusting cap 10 to rise and fall. When the first water outlet 11 overlaps with the nozzle 3, the water sprayed will be sprayed according to the diameter of the first water outlet 11. When the second water outlet 12 overlaps with the nozzle 3, the water sprayed will be sprayed according to the diameter of the second water outlet 12, thereby realizing automatic water volume adjustment.

[0030] It should be noted that the diameter of the second water outlet 12 is half an inch, the diameter of the first water outlet 11 is three-quarters of an inch, the controller 4 and the electric telescopic rod 9 are electrically connected, the controller 4, the soil moisture sensor 5 and the electric telescopic rod 9 are connected to an external power source, and the water inlet pipe 7 is used to connect to an external water pipe.

[0031] Preferably: a water-blocking cover 14 is connected to the outer wall of the connecting pipe 2. The water-blocking cover 14 has grooves 15 on both sides. Two connecting plates 16 are connected to the outer walls of the two sides of the water-blocking cover 14 respectively. A pin 17 passes through the top of the two connecting plates 16. Connecting blocks 18 are connected to the outer walls of the two sides of the soil moisture sensor 5. A slot 19 is opened on the top of the connecting block 18. The connecting block 18 is embedded in the groove 15. The slot 19 is matched with the size of one end of the pin 17, and one end of the pin 17 is circular.

[0032] In practical use, the pin 17 is pulled out of the slot 19 and the through hole of the connecting plate 16 by pulling the ring, and then the soil moisture sensor 5 is pulled outward to make the connecting blocks 18 on both sides disengage from the groove 15, so that the soil moisture sensor 5 can be easily disassembled.

[0033] Conversely, during installation, first embed the connecting blocks 18 on both sides of the soil moisture sensor 5 into the grooves 15, and then insert one end of the pin 17 from the top of the connecting plate 16 and the slot 19 in sequence. This completes the installation and fixation of the soil moisture sensor 5.

[0034] Working principle: First, place the base 1 in the designated position and insert the detection probe 6 into the soil. Then, use the soil moisture sensor 5 to collect soil moisture information. Then, according to the soil moisture, control the electric telescopic rod 9 through the controller 4 to drive the adjusting cap 10 to rise and fall. When the first water outlet 11 overlaps with the nozzle 3 hole, the water sprayed will be sprayed according to the diameter of the first water outlet 11. When the second water outlet 12 overlaps with the nozzle 3 hole, the water sprayed will be sprayed according to the diameter of the second water outlet 12, thereby realizing automatic water volume adjustment. Then, pull the pin 17 through the ring to pull it out of the slot 19 and the through hole of the connecting plate 16. Then, pull the soil moisture sensor 5 outward to disengage the connecting blocks 18 on both sides from the groove 15, thereby facilitating the disassembly of the soil moisture sensor 5.
