Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural irrigation, and particularly relates to a water-saving drip irrigation device suitable for greenhouse irrigation. Background Art

[0002] Drip irrigation is the use of pipes to deliver water to the roots of crops through orifices or drippers for local irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas.

[0003] For example, patent number CN202111040215.2 is a water-saving sprinkler equipment for agricultural irrigation, which can irrigate crops and supply water to the roots and upper parts of crops at the same time, thereby improving the absorption efficiency of crops and saving water. It is simple to operate and has strong practicality.

[0004] However, the device has a drip irrigation mechanism, which is fixedly connected to the outlet pipe on the water collecting box and can be buried in the soil to directly irrigate the roots and stems of crops; after the drip irrigation mechanism is buried in the soil, the soil will block the drip irrigation mechanism. When the water flow rate of the drip irrigation mechanism is small and the water flow speed is slow, the water flow is not easy to flush away the soil attached to the drip irrigation mechanism. When the drip irrigation mechanism stops drip irrigation, the moist soil will adhere to the drip irrigation mechanism. When the moist soil gradually becomes dry, the soil on the drip irrigation mechanism will be tightly adhered to the drip irrigation mechanism, resulting in the drip irrigation mechanism The next time the drip irrigation mechanism performs drip irrigation, the water output of the drip irrigation mechanism is slow and the drip irrigation mechanism is blocked; when the water flow rate of the drip irrigation mechanism is large and the water flow speed is fast, the water flow will flush away the soil attached to the drip irrigation mechanism, causing pits in the soil and even exposing the roots of crops. Utility Model Content

[0005] Based on this, the utility model provides a water-saving drip irrigation device and a drip irrigation control method suitable for greenhouse irrigation, so as to solve the technical problems existing in the prior art that the soil on the drip irrigation mechanism will be tightly adhered to the drip irrigation mechanism, resulting in the drip irrigation mechanism to output water slowly when the drip irrigation mechanism performs drip irrigation next time; or when the water flow rate of the drip irrigation mechanism is large and the water flow speed is fast, the water flow will flush away the soil to which the drip irrigation mechanism is attached, causing pits in the soil and even exposing the roots of crops.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A water-saving drip irrigation device suitable for greenhouse irrigation comprises a water collecting box, a water flow control component, a plurality of drip irrigation pipes, a first isolation pipe and a second isolation pipe, wherein the water collecting box is used to provide drip irrigation water or a water-fertilizer mixed liquid, the water flow control component is arranged on the water collecting box, the drip irrigation pipe is connected to the water collecting box, a plurality of the drip irrigation pipes are laid flat, a drip irrigation port is arranged on the drip irrigation pipe, the first isolation pipe and the second isolation pipe can be mutually clamped and buckled on the drip irrigation pipe, and a closed chamber is formed between the first isolation pipe and the second isolation pipe.

[0008] Preferably, a plurality of bifurcated nozzles are arranged on the drip irrigation pipe at a preset distance, and the plurality of bifurcated nozzles are arranged on both sides of the drip irrigation pipe and are arranged alternately in sequence.

[0009] Preferably, the bifurcated nozzle comprises a curved branch pipe and a spray port, the curved branch pipe is communicated with the drip irrigation port, and the spray port is detachably connected to the end of the curved branch pipe.

[0010] Preferably, a concave hole is provided on the first isolation tube, and a protrusion is provided on the second isolation tube, and the concave hole is matched with the protrusion.

[0011] Preferably, a plurality of strip-shaped partition plates are arranged in the first isolation tube and the second isolation tube, and the plurality of strip-shaped partition plates are arranged side by side in the first isolation tube and the second isolation tube in sequence.

[0012] Preferably, three groups of strip-shaped partition plates are provided.

[0013] Preferably, a plurality of humidity monitors and temperature monitors are provided on the first isolation tube or the second isolation tube.

[0014] Compared with the prior art, the utility model has at least the following advantages:

[0015] (1) It has excellent water-saving performance. The water flowing out of the drip irrigation pipe is supplied to crops underground because the first isolation tube and the second isolation tube are buckled on the drip irrigation pipe and buried in the soil, thereby reducing water evaporation and achieving better water-saving performance.

[0016] (2) The roots of crops are more likely to absorb water. Since the drip irrigation pipe and the drip irrigation isolation pipe are buried in the soil, the water supplied by the drip irrigation pipe is closer to the roots of crops, which can greatly improve the water absorption efficiency of crops.

[0017] (3) Preventing water blockage. Since a closed chamber is formed between the first isolation tube and the second isolation tube and the drip irrigation tube, the water flowing out of the drip irrigation tube sprays on the inner walls of the first isolation tube and the second isolation tube, and then falls on the soil surface along the inner walls of the first isolation tube and the second isolation tube, and slowly penetrates into the soil. Therefore, the water flow rate of the drip irrigation port of the drip irrigation tube is slow, which will not cause the soil to block the drip irrigation port, or the water flow rate of the drip irrigation port of the drip irrigation tube is fast, which will not cause the water flow to wash away the soil to which the drip irrigation mechanism is attached, causing pits in the soil, or even exposing the roots of crops.

[0018] (4) Optimizing the space for planting crops. Since underground water supply is adopted and the first isolation pipe and the second isolation pipe are used for isolation and protection, the surface between the crop rows is dry. During the process of drip irrigation of crops, the crops can be repaired and racks can be erected. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please see Figure 1 A water-saving drip irrigation device suitable for greenhouse irrigation includes a water collecting box 10, a water flow control member 20, a plurality of drip irrigation pipes 30, a first isolation pipe 40 and a second isolation pipe 50. The water collecting box 10 is used to provide drip irrigation water or a water-fertilizer mixed liquid. The water flow control member 20 is arranged on the water collecting box 10. The water flow control member 20 is a water flow switch used for water circulation control, water inlet and outlet control, water temperature control, water pump switch control, valve on-off control and other processes. The drip irrigation pipe 30 is connected to the water collecting box 10, and a plurality of the drip irrigation pipes 30 are laid flat. Generally, during the greenhouse seedling raising period or the seedling growth period, strip tunnels are dug between the rows of crops, and the main pipe and the branch pipe are arranged to connect the main pipe with the water collecting box 10. On the outside of the rows between the crops The main pipe is arranged, and the branch pipe is detachably connected to the main pipe. The branch pipe is arranged in the excavated strip tunnel. The drip irrigation pipe 30 is provided with a drip irrigation port 30, and the drip irrigation port 30 is arranged on both sides of the drip irrigation pipe 30. Water can flow out from the drip irrigation port 30 and spray out in a spray shape and flow into the strip tunnel. The first isolation tube 40 and the second isolation tube 50 can be mutually engaged and buckled on the drip irrigation pipe 30, and a closed chamber is formed between the first isolation tube 40 and the second isolation tube 50. The first isolation tube 40 and the second isolation tube 50 are buried in the soil with soil. When the water can be sprayed out from the drip irrigation port 30, it will be sprayed on the inner wall of the first isolation tube 40 and the second isolation tube 50, and fall on the soil in the closed chamber, and the moisture gradually penetrates into the root system of the crop.

[0030] The effects achieved are:

[0031] (1) It has excellent water-saving performance. The water flowing out of the drip irrigation pipe 30 is supplied to crops underground because the first isolation pipe 40 and the second isolation pipe 50 are buckled on the drip irrigation pipe 30 and buried in the soil, thereby reducing water evaporation and achieving better water-saving performance.

[0032] (2) The roots of crops can more easily absorb water. Since the drip irrigation pipe 30, the first isolation pipe 40 and the second isolation pipe 50 are buried in the soil, the water supplied by the drip irrigation pipe 30 is closer to the roots of crops, which can greatly improve the water absorption efficiency of crops.

[0033] (3) Preventing water blockage. Since a closed chamber is formed between the first isolation tube 40 and the second isolation tube 50 and the drip irrigation tube 30, the water jets out of the drip irrigation tube 30 on the inner walls of the first isolation tube 40 and the second isolation tube 50, and then falls on the soil surface along the inner walls of the first isolation tube 40 and the second isolation tube 50, and slowly penetrates into the soil. Therefore, the water flow rate of the drip irrigation port 30 of the drip irrigation tube 30 is slow, which will not cause the soil to block the drip irrigation port 30, or the water flow rate of the drip irrigation port 30 of the drip irrigation tube 30 is fast, which will not cause the water flow to wash away the soil to which the drip irrigation mechanism is attached, causing pits in the soil, or even exposing the roots of crops.

[0034] (4) Optimizing the space for planting crops. Because underground water supply is adopted and the first isolation tube 40 and the second isolation tube 50 are used for isolation and protection, the surface between the crop rows is dry. During the process of drip irrigation of crops, the crops can be repaired and racks can be erected.

[0035] In a possible embodiment, a plurality of forked nozzles 320 are arranged at a preset distance on the drip irrigation pipe 30, and the plurality of forked nozzles 320 are arranged on both sides of the drip irrigation pipe 30 and are arranged alternately in sequence. When the plurality of forked nozzles 320 are arranged alternately, the atomized water flow sprayed from the forked nozzles 320 can be evenly sprayed in the closed chamber and slowly penetrate into the soil.

[0036] In a preferred embodiment, the bifurcated nozzle 320 includes a curved branch pipe 321 and a spray port 322. The curved branch pipe 321 is connected to the drip irrigation port 30, and the spray port 322 is detachably connected to the end of the curved branch pipe 321. When the spray port 322 is blocked, the spray port 322 can be replaced.

[0037] In a possible embodiment, a concave hole is provided on the first isolation tube 40, and a protrusion is provided on the second isolation tube 50, and the concave hole is matched with the protrusion. The first isolation tube 40 and the second isolation tube 50 are formed by splicing a plurality of sections in sequence. During use, the drip irrigation tube 30 is first placed in the strip tunnel, and the first isolation tube 40 is installed on one side of one end of the drip irrigation tube 30, and the second isolation tube 50 is installed on the opposite side. The first isolation tube 40 and the second isolation tube 50 are close to each other, and the protrusion is clamped in the concave hole to fix the first isolation tube 40 and the second isolation tube 50. The drip irrigation tube 30 is located between the first isolation tube 40 and the second isolation tube 50, and the drip irrigation tube 30 is fastened in the middle, and a plurality of the first isolation tubes 40 and the second isolation tubes 50 are spliced ​​in sequence until they are buckled on the entire drip irrigation tube 30. The first isolation tube 40 and the second isolation tube 50 are easy to disassemble or install, and at the same time, have the function of clamping the drip irrigation tube 30.

[0038] In a possible embodiment, a plurality of strip partition plates 60 are disposed in the first isolation tube 40 and the second isolation tube 50. The plurality of strip partition plates 60 are sequentially arranged side by side in the first isolation tube 40 and the second isolation tube 50. When the strip partition plates 60 are sequentially arranged side by side in the first isolation tube 40 and the second isolation tube 50, the first isolation tube 40 and the second isolation tube 50 are divided into a plurality of water collection chambers. The functions of the strip partition plates 60 are: (1) water distribution. The water flowing out of the spray port 322 can fall into different chambers divided by the plurality of strip partition plates 60, and evenly penetrate the soil to prevent the water flow from being uneven due to the uneven strip tunnel. (1) The first and second isolation tubes 40 and 50 are not straight, and they gather together, resulting in more water flow gathering in some tunnels and less water flow gathering in some tunnels. As a result, the soil in places where water flow gathers more is soft, and pits are easily formed after being stepped on; (2) The force-bearing surface is increased. Since the isolation tubes are mostly similar to half-cut tubes, when the first isolation tube 40 and the second isolation tube 50 are subjected to vertical downward force, they are easy to deform. By providing the plurality of strip partitions 60, the force-bearing surface of the first isolation tube 40 and the second isolation tube 50 can be increased, and the isolation tubes are not easy to deform; (3) By providing the plurality of strip partitions 60, the drip irrigation tube 30 will be fastened between the strip partitions 60 to prevent the drip irrigation tube 30 from deflecting.

[0039] In a preferred embodiment, one group of the strip-shaped partition plates 60 is provided. One group of the strip-shaped partition plates 60 is respectively provided on the first isolation tube 40 and the second isolation tube 50, and is divided into one symmetrical water collection chamber on the left and one on the right.

[0040] In a preferred embodiment, two groups of the strip-shaped partition plates 60 are provided. The two groups of the strip-shaped partition plates 60 are respectively provided on the first isolation tube 40 and the second isolation tube 50, and are divided into two symmetrical water collection chambers on the left and right.

[0041] In a preferred embodiment, three groups of the strip-shaped partition plates 60 are provided. The three groups of the strip-shaped partition plates 60 are respectively provided on the first isolation tube 40 and the second isolation tube 50, and are divided into three symmetrical water collection chambers on the left and right.

[0042] In a possible embodiment, a plurality of humidity monitors 410 and temperature monitors 420 are disposed on the first isolation tube 40 or the second isolation tube 50. The plurality of humidity monitors 410 and temperature monitors 420 are sequentially disposed on the first isolation tube 40 or the second isolation tube 50 at a preset distance. When the drip irrigation tube 30 sprays water, if the humidity monitor 410 detects that the difference between the soil humidity of a certain section and the soil humidity of other sections is too large, it indicates that the drip irrigation port 30 of the section may be blocked, and the first isolation tube 40 and the second isolation tube 50 of the section are opened, and the bifurcated nozzle 320 is replaced.

[0043] Specifically, the water supply of the water collecting box 10 is controlled by the water flow control component 20 according to the soil moisture and soil temperature monitored by the humidity monitor 410 and the temperature monitor 420 provided on the first isolation tube 40 or the second isolation tube 50. Specifically, the humidity monitor 410 and the temperature monitor 420 monitor the soil moisture and soil temperature in unit time, and the unit time is 1h. The soil moisture monitored by the humidity monitor 410 will generate a humidity monitoring signal and transmit it to the water flow control component 20. The water flow control component 20 responds to the humidity monitoring signal and makes a judgment. If the current soil moisture is within the soil moisture range under the standard state, the water collecting box 10 and the drip irrigation pipe 30 are not connected. If the current soil moisture is lower than the soil moisture under the standard state, the water collecting box 10 and the drip irrigation pipe 30 are connected to supply water to the soil. The soil temperature monitored by the temperature monitor 420 generates a temperature monitoring signal and transmits it to the water flow control component 20. The water flow control component 20 responds to the temperature monitoring signal and makes a judgment. If the current soil temperature is within the soil temperature range under the standard state, the water collecting tank 10 and the drip irrigation pipe 30 are not connected. If the current soil temperature is higher than the soil temperature under the standard state, the water collecting tank 10 and the drip irrigation pipe 30 are connected to spray water on the soil. By monitoring the soil moisture and temperature, the current soil state can be accurately judged, and water can be sprayed on the soil reasonably.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
