Description

Technical Field

[0001] This application relates to the field of sprinkler irrigation technology, and more particularly to a water-saving sprinkler irrigation device for agricultural use. Background Technology

[0002] In agricultural planting, after fruit trees or other trees are planted, they need to be irrigated regularly to ensure sufficient water resources for healthy growth. With the development of technology, there are many types of irrigation devices on the market. Most of them use pipes to transport water, with a certain number of sprinklers or drains installed on the side walls of the pipes for unified irrigation. This solves the cumbersome nature of traditional manual irrigation and improves irrigation efficiency.

[0003] However, existing irrigation devices still have some problems in use. First, the irrigation nozzles are basically exposed. There is a lot of dust and dirt in the orchard, and fallen leaves are always falling on the irrigation nozzles. Over time, these will damage the irrigation nozzles. If one end is blocked or corroded, the irrigation nozzle will leak water. This not only wastes water, but also affects the irrigation effect. Second, when irrigating the roots of trees, the irrigation inlet is easily blocked by soil, which not only affects the uniformity of water output, but also requires a high maintenance rate.

[0004] In view of this, this application proposes a water-saving sprinkler irrigation device for agricultural use. Summary of the Invention

Under the action of the pneumatic control mechanism, the pneumatic probe mechanism and the pressure plate mechanism are driven synchronously. Before irrigation, the water guide part and the nozzle are protruded first, and then the irrigation is distributed through the water supply pipes. This can irrigate both the roots and branches of crops, making full use of water resources and saving energy and protecting the environment. The entire irrigation process is completed automatically, without the need for workers to go to the field to operate it.

[0017] After irrigation is completed, the water guide section is retracted into the straight cylinder under the action of the pressure plate mechanism, which plays a protective role for the bottom of the irrigation system, ensuring smooth water flow for each irrigation and guaranteeing the irrigation effect.

[0018] This application incorporates a probe and a protective element. At the start or end of irrigation, a pneumatic probing mechanism drives the probe and protective element. During irrigation, the pneumatic probing mechanism first drives the protective element, causing the protective cover to move upwards, and then drives the probe, causing the transmission sleeve to extend the nozzle. During irrigation, the protective cover does not obstruct the nozzle in any direction. After irrigation, the pneumatic probing mechanism first drives the probe, then the protective element, to retract the nozzle. The protective cover then covers the outside of the nozzle, providing all-around protection against dust, rain corrosion, etc., effectively preventing localized water seepage during irrigation, fully utilizing water resources, and ensuring even spraying of branches and leaves.

When the piston plate a81 moves upward and touches the pressure sensor b58, the pressure sensor b58 sends an electrical signal to the controller, which controls the reciprocating pump to close (stop inflating). When one of the limit rods a82 touches the pressure sensor a57, the pressure sensor a57 sends an electrical signal to the controller, which controls the reciprocating pump to close (stop inhaling).The output terminals of pressure sensors C59 and D510 are electrically connected to the controller, and the output terminal of the controller is electrically connected to the solenoid valve 56. When the protrusion 94 touches the pressure sensor C59, the pressure sensor C59 sends an electrical signal to the controller, which closes the solenoid valve 56 (stops air intake); when the protrusion 94 touches the pressure sensor D510, the pressure sensor D510 sends an electrical signal to the controller, which closes the solenoid valve 56 (stops inflation). The entire process can be automatically controlled, eliminating the need for manual operation in the fields, saving manpower and time, and effectively avoiding water waste.

[0030] The working principle of this embodiment is as follows: First, the device is installed in an agricultural garden that requires individual irrigation. Each straight cylinder 1 is installed next to a fruit tree or other tree, with the nozzle 45 and water guide 63 facing the tree. The tip of the insertion rod 13 is inserted into the soil, with the contact plate touching the upper end of the ground. Then, the straight cylinder 1 is installed vertically on the ground. Figure 1The diagram shows a partial view of the device. Several straight cylinders 1 can be set up according to the planting situation. The structure of each straight cylinder 1 is basically the same (pressure sensor a57 and pressure sensor b58 can be installed in one of the straight cylinders 1, preferably in the end straight cylinder 1). When irrigation is required, the external reciprocating pump is started first. The reciprocating pump is a reciprocating air pump, which can provide positive pressure blowing or negative pressure suction. One end of the main air pipe 51 is connected to the reciprocating pump, and the positive or negative pressure start of the air control mechanism 5 is controlled by the reciprocating pump. Before irrigation, the device drives a reciprocating pump to fill the main air pipe 51 with gas. The gas in the main air pipe 51 enters several branch air pipes a53 and b54 through several adapter pipes 52. The gas in branch air pipe b54 enters below the circular plate b11 and pushes the piston plate b91 downward under the action of air pressure (positive pressure). The downward movement of piston plate b91 pushes the chassis 62 downward through the connecting rod 93, thereby moving the water guide 63 to the lower end of the straight cylinder 1. When the protrusion 94 contacts the strip plate 95, the protrusion 94 will touch the pressure sensor d510. After the pressure sensor d510 pressurizes, it will send an electrical signal to the controller, which will close the solenoid valve 56. At this time, the gas input in branch air pipe b54 stops, and the piston plate b91 remains stationary. When gas is introduced into the upper part of the circular plate a10 through the gas distribution pipe a53, the positive pressure pushes the piston plate a81 upward (note that the distance that piston plate a81 moves is greater than the distance that piston plate b91 moves). When piston plate a81 moves upward, it first pushes the protective cover 71 upward through the two push rods 83, and the protective cover 71 will rise above the nozzle 45. At this time, piston plate a81 will continue to move upward. The rack 125 on the side wall of one of the push rods 83 meshes with the gear 124, which in turn drives the lead screw 123 to rotate. The rotation of the lead screw 123 will cause the transmission sleeve 121 on its side wall to slide away from the straight cylinder 1, thereby causing the nozzle 45 to slide out to the outside of the protective cover 71. At this time, piston plate a81 contacts and squeezes the pressure sensor b58 on the inner wall of the limiting ring 84. After the pressure sensor b58 receives pressure, it sends an electrical signal to the controller, and the controller shuts down the reciprocating pump. At this time, both nozzle 45 and water guide 63 are in the extended state.

[0031] The controller starts the centrifugal pump, which is connected to one end of the main pipe 41 to supply water into the main pipe 41. The water in the main pipe 41 enters the branch pipes a42 and b43. The water in the branch pipe a42 is transported to the nozzle 45 through the hose 44, and then sprayed upward at an angle through the nozzle 45 to spray water on the branches and leaves of fruit trees or other trees. The water in the branch pipe b43 flows into the bottom of the straight cylinder 1 and is guided to the roots of the trees through the water guide 63. After irrigation is completed, the centrifugal pump is turned off.

[0032] The next step is to restart the reciprocating pump via the controller to draw air into the main air pipe 51, creating a negative pressure in the main air pipe 51. This, in turn, creates a negative pressure between the upper end of circular plate a10 and the lower end of circular plate b11. When a negative pressure is created at the lower end of circular plate b11, the piston plate b91 moves upward under the action of the negative pressure, which in turn pulls the chassis 62 upward via the connecting rod 93 (see reference). Figure 5 In the state where the two limit rods b96 are in contact with the strip plate 95, the piston plate b91 moves to the highest position, the protrusion 94 abuts against the bottom end of the circular plate b11, and the protrusion 94 is squeezed against the pressure sensor c59. After the pressure sensor c59 is subjected to pressure, it will send an electrical signal to the controller, and the controller will close the solenoid valve 56. At this time, the air pressure under the circular plate b11 remains stable. When the air distribution pipe a53 draws in air, a negative pressure is generated above the circular plate a10, causing the piston plate a81 to move downwards. This moves the two push rods 83 downwards. The rack 125 on the side wall of one of the push rods 83 meshes with the gear 124 in the opposite direction, causing the lead screw 123 to rotate in the opposite direction. This causes the transmission sleeve 121 to retract into the straight cylinder 1, returning the nozzle 45 to its original position (the meshing of the rack 125 and the gear 124 ends). At this time, the piston plate a81 continues to move downwards, pulling the protective cover 71 downwards through the two push rods 83. This cover is then placed on the upper end of the support ring 72, providing all-round protection for the nozzle 45. This prevents dust and fallen leaves from clogging the nozzle, as well as preventing corrosion from rainwater, ensuring that the nozzle 45 maintains good spraying and irrigation conditions without any leakage. When the two limit rods a82 abut against the upper end of the circular plate a10, one of the limit rods a82 is squeezed against the pressure sensor a57. After the pressure sensor a57 is subjected to pressure, it sends an electrical signal to the controller, which shuts down the reciprocating pump. At this time, the transmission sleeve 121 and the nozzle 45 are both housed inside the protective cover 71, and the protective cover 71 fits and covers the upper end of the support ring 72.
