Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production drip irrigation, in particular to a timing drip irrigation device used for potato planting. Background Art

[0002] Drip irrigation is the use of plastic pipes to deliver water to the roots of crops through the orifices or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is one of the most effective water-saving irrigation methods in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a high water-saving and yield-increasing effect and can be applied to irrigation of fruit trees, vegetables, cash crops and greenhouses.

[0003] Traditional drip irrigation is a periodic over-irrigation, but the amount of water absorbed by crops is limited. Each irrigation requires manual timing to open and close the water valve while observing the water consumption. A large amount of water may make it difficult for the roots of crops to breathe, causing rot. It is time-consuming and labor-intensive, and the amount of water is difficult to control. In order to solve the timing and quantitative problems of drip irrigation during crop growth, a drip irrigation device that meets the requirements is designed. Utility Model Content

[0004] The utility model solves the problem of providing a timed drip irrigation device for potato planting, which solves the technical problem of time-consuming and labor-intensive manual timed and quantitative control of water valves during drip irrigation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A timed drip irrigation device for potato planting comprises a water tank, a water inlet pipe is installed at the top of the water tank, a main valve is installed between the water tank and the water inlet pipe, a water outlet pipe is installed at the bottom of the water tank, a plurality of limit rods are fixedly installed at the lower end of the water tank, a first float is provided on the sliding case inside the limit rod, a second float is connected to the bottom of the first float, a rubber plug is installed at the bottom of the second float, a limit block is installed on the side of the second float, a telescopic rod is installed on the top of the first float, a control box is installed at the top of the water tank, a first annular magnet and a second annular magnet are respectively installed at the bottom of both sides of the control box, a conductive block is rotatably installed inside the control box, a third annular magnet and a fourth annular magnet are respectively installed at two sections of the conductive block, a plurality of fixing rods are fixedly installed at the bottom of the water outlet pipe, and a plurality of drip regulating mechanisms are installed at the side end of the water outlet pipe.

[0007] Preferably, the water tank is conductively connected to the water inlet pipe, and the water tank is conductively connected to the water outlet pipe.

[0008] Preferably, the first float and the second float are connected by a connecting rope, a limiting groove is provided inside the limiting rod, and the limiting block is limited to move up and down in the limiting groove.

[0009] Preferably, a limiting hole is provided at the bottom of the control box, and the telescopic rod passes through the limiting hole to be connected to the bottom of the conductive block.

[0010] Preferably, a contact is installed in the middle of the second annular magnet, and when the contact touches the bottom of the conductive block, the other end of the conductive block touches the negative pole.

[0011] Preferably, the drip regulating mechanism is composed of a dripper, a regulating valve, a conical plug, a conical hole and a threaded regulating rod, the drip regulating mechanism is provided with a dripper on the side, the drip regulating mechanism is provided with a threaded regulating rod inside, the threaded regulating rod is provided with a regulating valve at one end, the threaded regulating rod is provided with a conical plug at the other end, and the drip regulating mechanism is provided with a conical hole inside.

[0012] Preferably, the conical hole is connected to the dripper, the conical plug can block the conical hole, and the threaded adjustment rod is threadedly connected to one end of the drip adjustment mechanism.

[0013] The beneficial effect of the utility model is that the user controls the flow of water in the water inlet pipe through the control box. When there is no water in the water tank, the first float and the second float are located at the very bottom of the water tank. At this time, the telescopic rod on the top of the first float is in a stretched state, and the telescopic rod pulls one end of the conductive block to move downward. At this time, one end of the conductive block contacts with the contact, and the other end of the conductive block contacts with the other end contact. At this time, the control box is energized, the water pump starts working, and the water in the water inlet pipe flows into the water tank. At this time, the rubber plug blocks the hole at the bottom of the water tank, and water cannot flow into the outlet pipe, thereby achieving the effect of automatic water inlet.

[0014] When the water tank is full of water, the first float floats up and the telescopic rod is compressed. When the telescopic rod is compressed to the moving length and stops shortening, the telescopic rod moves up against one end of the conductive block, and the two ends of the conductive block are separated from the contacts. The control box is powered off, the water pump stops working, and stops supplying water to the water tank. While the first float moves up, the second float is pulled by the connecting rope, so that the rubber plug is separated from the hole at the bottom of the water tank. The rubber plug will float up under the buoyancy of the second float. At this time, water flows into the outlet pipe and will be diverted to each drip adjustment mechanism to start drip irrigation, realizing automatic power off and achieving the effect of timed drip irrigation.

[0027] Secondly, the water tank 1 is conductively connected to the water inlet pipe 2 , and the water tank 1 is conductively connected to the water outlet pipe 4 , so that water enters the water tank 1 through the water inlet pipe 2 .

[0028] Furthermore, the first float 6 and the second float 8 are connected by a connecting rope 7, a limiting groove 11 is provided inside the limiting rod 5, and the limiting block 10 is limited to move up and down in the limiting groove 11, thereby realizing the up and down movement of the first float 6 and the second float 8.

[0029] Furthermore, a limiting hole 20 is provided at the bottom of the control box 13 , and the telescopic rod 12 passes through the limiting hole 20 and is connected to the bottom of the conductive block 17 , thereby realizing the control of the posture of the conductive block 17 by the telescopic rod 12 .

[0030] Furthermore, a contact 21 is installed in the middle of the second annular magnet 15. When the contact 21 touches the bottom of the conductive block 17, the other end of the conductive block 17 touches the negative pole, thereby realizing automatic control of electricity.

[0031] Furthermore, the drip regulating mechanism 23 is composed of a dripper 24, a regulating valve 25, a conical plug 26, a conical hole 27 and a threaded regulating rod 28. The dripper 24 is installed on the side of the drip regulating mechanism 23, and a threaded regulating rod 28 is installed inside the drip regulating mechanism 23. The regulating valve 25 is installed at one end of the threaded regulating rod 28, and the conical plug 26 is installed at the other end of the threaded regulating rod 28.

[0032] Finally, the conical hole 27 is connected to the dripper 24, the conical plug 26 can block the conical hole 27, and the threaded adjustment rod 28 is threadedly connected to one end of the drip adjustment mechanism 23, thereby achieving the adjustment of the water output.

[0033] Working principle: First, when the farmer starts to use it, there is no water in the water tank 1. At this time, the first float 6 and the second float 8 are at the bottom of the water tank 1, and the rubber plug 9 will block the hole at the bottom of the water tank 1, so that the water tank 1 is in a closed state. At this time, the telescopic rod 12 on the top of the first float 6 is stretched to the longest state, and the telescopic rod 12 pulls one end of the conductive block 17 inside the control box 13 to the bottom, and the other end is tilted, so that the two sections of the conductive block 17 are in contact with the contact 21, so that the conductive circuit of the water pump forms a pathway, and then the farmer connects the power supply. At this time, the water pump works, and water flows into the water tank 1 along the water inlet pipe 2. As the water level in the water tank 1 rises, the first float 6 will begin to float up under the buoyancy of the water, and the second float 8 will block the hole at the bottom of the water tank 1 under the action of the upper and lower pressure difference, and the first float 6 floats up. At the same time, the telescopic rod 12 gradually shortens. When the water level in the water tank 1 reaches a certain height, the telescopic rod 12 stops shortening and starts to move against one end of the conductive block 17, separating the two ends of the conductive block 17 from the contacts, so that the water pump is powered off and the water inlet pipe 2 stops supplying water to the water tank 1. At this time, the first float 6 separates the rubber plug 9 from the hole of the water tank 1 under the tension of the connecting rope 7. At the moment of separation, the second float 8 drives the rubber plug 9 to float to the bottom of the first float 6 under the buoyancy of the water. At this time, water flows into the outlet pipe 4 through the hole and is divided into each drip regulating mechanism 23. The threaded regulating rod 28 is rotated by manually twisting the regulating valve 25, and the tapered plug 26 is driven to move inside the drip regulating mechanism 23, so that the space size between the tapered hole 27 and the tapered plug 26 is adjusted to complete the drip rate adjustment.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
