Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation systems for melon planting, and in particular to a drip irrigation system for melon planting. Background Art

[0002] Muskmelon is an annual climbing herb of the genus Cucumis in the family Cucurbitaceae. It has heart-shaped leaves, unisexual yellow flowers, monoecious or bisexual flowers, and is spherical, ovoid, or oblate in shape. The skin is yellow, white, green or with various markings. The flesh is green, white, red or orange-yellow. The flesh is crisp or soft, and the taste is fragrant and sweet. It likes high temperature, dryness and plenty of sunshine. It is native to the tropics and is widely cultivated in various parts of my country. There are many varieties. The ones produced in North China and Northwest China are sweet and have a strong taste, while those produced in humid areas are more watery and have a lighter taste. It is one of the excellent fruits in summer. The shape and color of the fruit vary according to the variety. It has a fragrance, a smooth skin, and dirty white seeds. It is widely cultivated in temperate to tropical regions. It is cultivated in various parts of my country. There are many varieties and the fruit varies greatly. It can be divided into several varieties, and in horticulture it can be classified into several strains. Among them, muskmelon, Hami melon and honeydew melon also belong to different varieties or strains.

[0003] In melon cultivation, ridge planting is an important planting method. After the melon seedlings are planted on the ridges, drip irrigation will be laid on one side of the seedlings to provide moisture to the roots of the melon seedlings and help maintain stable soil moisture. After laying, a layer of film will be laid to moisturize the soil and inhibit the growth of weeds.

[0004] In the actual application of the existing drip irrigation system, clogging has become a major problem that needs to be solved urgently. Although the clogging caused by water impurities can be effectively reduced by installing a filter device at the end of the water pump, since the drip irrigation system is laid on the soil surface, over time, the drip irrigation drippers are easily invaded by impurities such as mud and sand in the external environment, which leads to clogging.

[0026] 1. The drip irrigation unit is set up to achieve that the position of the dripper assembly can be fixed by the ground rod during laying, and the position of the branch pipe can be fixed at the same time, so as to avoid displacement due to the impact of the water flow when water is inletted, and ensure that the dripper assembly corresponds to the melon seedlings one by one. During the water inlet process, the water entering the branch pipe will push the floating block to move upward, so that the water outlet hole is exposed, and at the same time, the shell moves upward, so that the drip hole is exposed. After the shell moves upward, the film of the dripper assembly will be lifted at the same time, so that the water will not be sprayed onto the surface of the film after being sprayed through the drip hole, so as to avoid the situation that the water will flow around after being sprayed onto the surface of the film, so that the melon seedlings can receive enough water. At the same time, after the drip irrigation of the melon seedlings is completed, the floating block will reset downward under the action of gravity, and drive the shell to move downward.

[0027] 2. Through the provided inner cavity adjustment unit, when drip irrigation is performed on the melon seedlings, when the melon seedlings on different ridges have a small water demand, the water flow entering the branch pipe can be reduced through the corresponding first three-way valve or the first two-way valve, and at the same time, the second three-way valve or the second two-way valve on the air transmission pipe corresponding to the position of the branch pipe is opened, and then the air pump is started to make the air bag in the branch pipe swell, so that the inner cavity space of the branch pipe is reduced, so that the flow rate is increased when the water flow is small, and then the water can flow quickly to the end away from the valve, thereby avoiding the situation that when the water flow is small, the water output at the end away from the valve is also small, and the melon seedlings at this end cannot receive enough water.

The surface of the ground rod 436 is provided with barbs to prevent the ground rod 436 from being easily pulled out.

[0057] like Figure 4 , Figure 5 and Fig.10 As shown, the protection component 45 includes a shell 451, a through hole is provided on the connector 431 to insert a push rod 452, a floating block 453 is fixed to one end of the push rod 452 inserted into the connector 431, and the top of the push rod 452 is fixed to the shell 451. Preferably, a sealing ring is provided on the inner wall of the through hole, so that the push rod 452 and the through hole are in a sealed state;

[0059] Specifically, when not in use, the shell 451 covers the outside of the buffer seat 432 to shield the outside of the buffer seat 432, so that external mud and sand will not contact the drip hole 433, thereby ensuring that the drip hole 433 will not be blocked.

[0060] like Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the inner cavity adjustment unit 50 includes an air pump 51 and an air delivery component 52 mounted on the air pump 51, an air bag 53 is fixed on the inner bottom wall of the branch pipe 41, and the air delivery component 52 is connected to the air bag 53;

[0061] The gas delivery assembly 52 includes an air delivery pipe 521 connected to the air pump 51, and a plurality of second three-way valves 522 are installed on the air delivery pipe 521. A second two-way valve 523 is fixed to one end of the air delivery pipe 521, and an air supply pipe 524 is fixed to the branch pipe 41. One end of the second three-way valve 522 and the second two-way valve 523 are respectively fixed to one end of the plurality of air supply pipes 524, and the other end of the air supply pipe 524 is fixed in the inflation port of the airbag 53.

[0062] When the water flow in the branch pipe 41 is small, the air pump 51 is used to inflate the airbag 53 in the corresponding branch pipe 41, so that the airbag 53 gradually swells and fills the inner cavity of the branch pipe 41, thereby reducing the inner cavity space and increasing the water flow speed.

[0063] Specifically, when the melon planting drip irrigation system is working / in use:

[0064] First, the main pipe 31, the first three-way valve 32, and the first two-way valve 33 are set according to the actual planting position of the melon seedlings on the ridge, and then the branch pipe 41 is installed. After the branch pipe 41 is installed on the corresponding valve, the dripper assembly 43 is then installed into the outlet pipe 42 and clamped by a pipe clamp. After fixing, the ground rod 436 is fixed in the soil to position the dripper assembly 43. After all the ground rods 436 in the dripper assembly 43 are inserted into the soil, the position of the branch pipe 41 is fixed accordingly, and then the air delivery assembly 52 is assembled according to the assembly, and after assembly, it is connected and fixed with the air delivery pipe 524 exposed outside the branch pipe 41;

[0065] When drip irrigation is performed on the melon seedlings, the water pump 21 is started to send the water in the water reservoir 10 into the main pipe 31, and then into each branch pipe 41. The water entering the branch pipe 41 pushes the float 453 to move upward, so that the water outlet hole is exposed. At the same time, the top rod 452 on the float 453 pushes the shell 451 to move upward, so that the drip hole 433 is exposed. After the shell 451 moves upward, it will simultaneously lift up the film of the drip head assembly 43, so that the water will not be sprayed onto the surface of the film after being sprayed out through the drip hole 433. , can be sprayed directly around the root system of the melon seedlings, avoiding the situation that the water will flow around after being sprayed on the surface of the film, so that the melon seedlings can receive enough water. At the same time, after the drip irrigation of the melon seedlings is completed, the floating block 453 is reset downward under the action of gravity, and drives the shell 451 to move downward. While moving, the inner wall of the bottom end of the shell 451 will scrape the filter sheet 434 on one side of the drip hole 433, and at the same time, the filter sheet 434 and the drip hole 433 are shielded after resetting;

[0066] During drip irrigation of the melon seedlings, when the melon seedlings on different ridges have a smaller water demand, the first three-way valve 32 or the first two-way valve 33 at the corresponding branch pipe 41 is rotated to reduce the water flow entering the branch pipe 41, and then the second three-way valve 522 or the second two-way valve 523 on the air pipe 521 corresponding to the position of the branch pipe 41 is opened, and then the air pump 51 is started to inflate the air bag 53 in the branch pipe 41 and gradually swell, so that the space in the inner cavity of the branch pipe 41 is reduced. After the space is reduced, the flow rate is increased when the water flow is small, so that the water can quickly flow to the end away from the valve, so that the melon seedlings away from the water inlet end can receive enough water.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
