Description

Technical Field

[0001] This utility model relates to the field of vegetable planting equipment technology, specifically a drip irrigation pipe for vegetable planting. Background Technology

[0002] In the field of vegetable cultivation, greenhouse farming, as a highly efficient agricultural production method, plays a crucial role in ensuring a stable supply of fresh vegetables, especially during winter in northern regions when the climate is unsuitable for natural vegetable growth. With the continuous advancement of agricultural technology, greenhouse vegetable yields have increased year by year, and the importance of planting and maintenance techniques has become increasingly prominent. Among these, irrigation technology is one of the key factors affecting vegetable growth and yield.

[0003] Currently, drip irrigation technology is widely used in greenhouse vegetable cultivation due to its high efficiency and water-saving advantages. This technology delivers water directly to the roots of vegetables, reducing evaporation and leakage during transport and significantly improving water resource utilization efficiency. However, existing vegetable drip irrigation systems still face some problems that urgently need to be addressed in practical applications.

[0004] Current drip irrigation technologies for vegetables primarily utilize drip heads with fixed orifice diameters. However, the rigid design of these drip heads ensures a consistent water flow, making it difficult to adjust for the varying water requirements of different vegetable varieties. Furthermore, the water needs of the same vegetable differ at different stages of growth, and insufficient water flow fails to meet the vegetable's growth requirements. Therefore, developing a drip irrigation system for vegetable cultivation that can automatically adjust water flow is of significant practical importance. Utility Model Content

[0005] To address the aforementioned issues, this application provides a drip irrigation pipe for vegetable cultivation.

[0006] To achieve the above objectives, this application provides the following technical solution: a vegetable planting drip irrigation pipe, including a water supply pipe, a branch pipe detachably connected to the water supply pipe, and a drip irrigation mechanism installed on the branch pipe. The drip irrigation mechanism includes a flow limiting component connected to the branch pipe and a flexible tube connected to the flow limiting component and drip irrigation the vegetables. The flexible tube has an opening.

[0007] When vegetables are drip-irrigated, the flow limiting component automatically adjusts the water flow rate into the hose according to the water pressure in the water supply pipe. When the water pressure in the water supply pipe increases, the flow limiting component controls the water flow to increase the flow rate into the hose.

[0008] Preferably, the flow limiting assembly includes a flow limiting column with openings at both ends connecting a branch pipe and a hose, a flow limiting tube axially inserted inside the flow limiting column and with one end connected to the opening of the connecting branch pipe, and a sealing column axially slidably inserted inside the flow limiting tube by an elastic element. The flow limiting tube has a flow limiting groove along its length that communicates with the inner tube. When the elastic element is in its normal elongated state, the end of the flow limiting column is located on the opening of the connecting branch pipe.

[0009] Preferably, the elastic element includes a control panel fixedly mounted on the end of the sealing column away from the branch pipe, and a first limiting spring sleeved on the body of the flow limiting pipe and connected at both ends to the inner wall of the flow limiting column and the control panel, respectively.

[0010] Preferably, the elastic element includes a control panel fixedly installed on the end of the sealing column away from the branch pipe, and two magnets sleeved on the body of the flow limiting pipe. The two magnets are respectively installed on the inner wall of the flow limiting column and the control panel, and the magnetic poles of the two magnets are the same at opposite ends.

[0011] Preferably, the elastic element includes a sliding sealing disc that passes through a movable groove at the end of the sealing column away from the branch pipe, and a second limiting spring that passes through the movable groove along the axial direction of the sealing column. The two ends of the second limiting spring are connected to the bottom wall of the movable groove and the sealing disc, and the sealing disc is located at the opening position of the movable groove when the second limiting spring is in the normal extended state. The sealing disc is installed inside the flow-limiting column through a connecting rod.

[0012] The beneficial effects of this utility model are as follows: the flow rate of water entering the drip irrigation hose is adjusted in real time based on water pressure by the flow limiting component, which can meet the precise water needs of vegetables at different growth stages, adjust the drip irrigation volume in real time, and reduce water waste. Compared with the fixed aperture drippers and manual adjustment methods in the prior art, the pipe realizes the automatic adjustment function of water flow through the flow limiting component, without the need for manual intervention, thus improving the efficiency and accuracy of irrigation.

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0021] Example 1: Reference Figures 1-5 The vegetable drip irrigation pipe shown includes a water supply pipe 1, a branch pipe 2 detachably connected to the water supply pipe 1, and a drip irrigation mechanism installed on the branch pipe 2. The drip irrigation mechanism includes a flow limiting component connected to the branch pipe 2 and a flexible hose 5 connected to the flow limiting component and used for drip irrigation of vegetables. The flexible hose 5 has an opening on its body. When the vegetables are drip irrigated, the flow limiting component automatically adjusts the water flow rate into the flexible hose 5 according to the water pressure in the water supply pipe 1. When the water pressure in the water supply pipe 1 increases, the flow limiting component controls the water flow to increase the flow rate into the flexible hose 5.

[0022] In this embodiment, the two ends of the flexible hose 5 are respectively connected to the two ends of the three-way connector 4 and are wrapped around the vegetables to form a ring structure. The other end of the three-way connector 4 is installed on the flow limiting component. When the water pressure in the water supply pipe 1 is adjusted, the flow limiting component adjusts the water flow rate into the flexible hose 5 in real time based on the water pressure, which is convenient to meet the different water needs of vegetables at different growth stages and improves the efficiency of drip irrigation adjustment.

[0023] Regarding the flow restriction component's adjustment of the water flow rate into the hose 5 based on the water pressure inside the water supply pipe 1, this embodiment provides the following solution.

[0024] like Figure 2 and Figure 4As shown, the flow limiting assembly includes a flow limiting column 3 connected to the branch pipe 2 and the hose 5 through openings 6 at both ends, a flow limiting pipe 7 axially inserted inside the flow limiting column 3 and connected at one end to the opening 6 of the branch pipe 2, and a sealing column 8 axially slidably inserted inside the flow limiting pipe 7 by an elastic element. The flow limiting pipe 7 has a flow limiting slot 11 that communicates with the inner pipe along its length. When the elastic element is in its normal elongated state, the end of the flow limiting column 3 is located on the opening 6 of the branch pipe 2.

[0025] In this embodiment, when the water pressure in the water supply pipe 1 changes, if the water pressure in the water supply pipe 1 is greater than the water pressure in the hose 5, the water in the water supply pipe 1 will push the sealing column 8, which passes through the flow limiting pipe 7, to move into the flow limiting column 3. During the movement of the sealing column 8, the opening of the flow limiting groove 11 gradually increases until the water pressure in the water supply pipe 1 is consistent with the water pressure in the hose 5. As the opening of the flow limiting groove 11 increases, the water flow rate entering the hose 5 also increases synchronously. Conversely, if the water pressure in the water supply pipe 1 is less than the water pressure in the hose 5, the water flow rate entering the hose 5 will also decrease synchronously, thus facilitating the adjustment of the drip irrigation water flow rate for different stages of vegetable cultivation, so as to meet the water needs of different stages of vegetable cultivation and improve the flexibility and convenience of drip irrigation.

[0026] It is understandable that the flexible installation of the sealing column 8 within the flow-limiting tube 7 can be achieved through various elastic elements. This embodiment provides the following solution:

[0027] like Figure 3 As shown, the first type of elastic element includes a control disc 9 fixedly disposed on the end of the sealing column 8 away from the branch pipe 2, and a first limiting spring 10 sleeved on the body of the flow limiting pipe 7 and connected at both ends to the inner wall of the flow limiting column 3 and the control disc 9 respectively.

[0028] In normal use, water flows into the water supply pipe 1. The pressure of the water flow enters the branch pipe 2 and pushes the sealing column 8, which is installed in the flow limiting pipe 7, to slide within the flow limiting pipe 7. At this time, the flow limiting slot 11 opens, and the water flows into the hose 5 through the flow limiting slot 11 to meet the water requirements of vegetable planting. At different stages of vegetable planting, the water flow rate in the water supply pipe 1 is increased or decreased, thereby increasing or decreasing the water pressure in the water supply pipe 1. When the water pressure increases or decreases, the sealing column 8 is pushed to move, and the thrust increases or decreases. Under the elastic force of the first limit spring 10, the water pressure increases or decreases. At this time, the first limit spring 10 will synchronously drive the sealing column 8 to slide within the flow limiting pipe 7, so that the flow limiting slot 11 increases or decreases, thereby adjusting the water flow rate entering the hose 5 in real time.

[0029] The elastic element includes a control panel 9 fixedly installed on the end of the sealing column 8 away from the branch pipe 2, and two magnets sleeved on the body of the flow limiting pipe 7. The two magnets are respectively installed on the inner wall of the flow limiting column 3 and the control panel 9. The magnetic poles of the two magnets are the same at opposite ends. The elastic sliding setting of the sealing column 8 in the flow limiting pipe 7 is achieved by the repulsive force between the two magnets.

[0030] like Figure 4 and Figure 5 As shown, the second type of elastic element includes a sliding sealing disc 14 that is inserted into a movable groove 12 at the end of the sealing column 8 away from the branch pipe 2, and a second limiting spring 13 that is inserted into the movable groove 12 along the axial direction of the sealing column 8. The two ends of the second limiting spring 13 are connected to the bottom wall of the movable groove 12 and the sealing disc 14, and the sealing disc 14 is located at the opening position of the movable groove 12 when the second limiting spring 13 is in the normal extended state. The sealing disc 14 is installed inside the flow-limiting column 3 through a connecting rod 15.

[0031] In normal use, water flows into the water supply pipe 1. The pressure of the water flow enters the branch pipe 2 and pushes the sealing column 8, which is installed in the flow limiting pipe 7, to slide within the flow limiting pipe 7. At this time, the flow limiting slot 11 opens, and the water flows into the hose 5 through the flow limiting slot 11 to meet the water requirements of vegetable planting. At different stages of vegetable planting, the water flow rate in the water supply pipe 1 is increased or decreased, thereby increasing or decreasing the water pressure in the water supply pipe 1. When the water pressure increases or decreases, the sealing column 8 is pushed to move, and the thrust increases or decreases. Under the action of the moving sealing column 8, the sealing slide 14 moves relative to the sealing column 8 in the moving slot 12, compressing the second limiting spring 13 located in the moving slot 12. Under the elastic force of the second limiting spring 13, the water pressure increases or decreases. At this time, the second limiting spring 13 will synchronously drive the sealing column 8 to slide within the flow limiting pipe 7, so that the flow limiting slot 11 increases or decreases, thereby adjusting the water flow rate entering the hose 5 in real time.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
