[0027] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the seedling planting drip irrigation equipment according to an embodiment of the present application with reference to the accompanying drawings.

[0029] like Figures 1-8 As shown, the seedling planting drip irrigation equipment of the embodiment of the present application may include: a supply device 1, a diversion mechanism 2 and multiple drip irrigation mechanisms 3.

[0030] The supply device 1 is connected to the diversion mechanism 2 .

[0031] The supply device 1 is used to provide irrigation water to the inside of the diversion mechanism 2 and the drip irrigation mechanism 3.

[0032] The diversion mechanism 2 includes a diversion tube 21 and a plurality of adjustment components 22 .

[0033] The shunt tube 21 is provided with a plurality of through holes 210 , and the plurality of adjustment components 22 are movably connected to the shunt tube 21 , respectively. The through holes 210 are located inside the adjustment components 22 .

[0034] The adjustment component 22 is used to adapt to the adjustment of the position of the drip irrigation mechanism 3 to prevent the drip irrigation pipeline from twisting after the position is adjusted, which may cause water channel blockage.

[0035] The plurality of drip irrigation mechanisms 3 are respectively connected to the corresponding regulating assemblies 22 . The drip irrigation mechanisms 3 include a plurality of first pipe bodies 31 , a plurality of second pipe bodies 32 and a plurality of branch pipe assemblies 33 .

[0036] The plurality of first tubes 31 are respectively communicated with the corresponding second tubes 32 , and the plurality of first tubes 31 and the plurality of second tubes 32 are arranged at intervals.

[0037] As a possible scenario, the first tube body 31 and the second tube body 32 are both made of hard rubber material, which has good corrosion resistance and a long service life. The first tube body 31 and the second tube body 32 are connected by threads. When a first tube body 31 or a second tube body 32 is damaged, the first tube body 31 or the second tube body 32 can be replaced separately, and the maintenance cost is relatively low.

[0038] As another possible situation, the first tube body 31 is made of hard rubber material, and the second tube body 32 is a flexible irrigation belt. The combination of the two can reduce the overall weight and facilitate collection and storage.

[0039] Multiple branch pipe assemblies 33 are respectively connected to the corresponding first pipe body 31, and the branch pipe assembly 33 includes an outer pipe 331, an inner pipe component 332 and a drip nozzle component 333, wherein,

[0040] The outer tube 331 is connected to the first tube body 31 , one end of the inner tube component 332 is inserted into the inner portion of the outer tube 331 , the inner tube component 332 and the outer tube 331 are slidably connected, and the nozzle component 333 is provided at the other end of the inner tube component 332 .

[0041] Specifically, during the seedling cultivation process, relevant technicians arrange the supply device 1 at a preset position (for example, the head and tail positions of the seedling greenhouse), and then lay multiple drip irrigation mechanisms 3 according to the plant spacing or the type of seedlings.

[0042] By changing the position of the adjustment component 22 on the diversion pipe 21, one end of the drip irrigation mechanism 3 is fixed, and then the multiple first tubes 31 and the multiple second tubes 32 are connected in sequence to fix the other end of the drip irrigation mechanism 3.

[0043] During use, the supply device 1 pressurizes and injects water into the diverter mechanism 2 and the multiple drip irrigation mechanisms 3. The irrigation water reaches the interior of the multiple drip irrigation mechanisms 3 through the diverter mechanism 2, and then is transmitted by the first tube body 31 and the second tube body 32. The irrigation water enters the interior of the branch pipe assembly 33 and flows out from the interior of the drip nozzle part 333. Since the pressure inside the drip irrigation mechanism 3 is relatively low during this process, the flow rate of the drip nozzle part 333 is relatively small, and there is no relative sliding between the outer tube 331 and the inner tube part 332.

[0044] After waiting for the preset irrigation time (which can be determined according to actual conditions), the supply device 1 applies pressure to the interior of the drip irrigation mechanism 3, and relative sliding occurs between the outer tube 331 and the inner tube component 332. The length of the branch pipe assembly 33 increases, and the position of the drip nozzle component 333 changes, thereby expanding the range of drip irrigation and meeting diverse planting needs.

[0045] After the irrigation is completed, the drip nozzle component 333 automatically closes one end of the inner tube component 332, and the supply device 1 pumps water from the inside of the drip irrigation mechanism 3. The pressure inside the drip irrigation mechanism 3 changes again, and relative sliding occurs between the outer tube 331 and the inner tube component 332 again, and the length of the branch pipe assembly 33 is reset.

[0046] It can be understood that, through the above-mentioned variable-length branch pipe assembly 33, the scope of drip irrigation is expanded, the laying of drip irrigation equipment is reduced, the cost is reduced, and the impact of the drip irrigation equipment on the seedling cultivation process is reduced.

[0047] In one embodiment of the present application, Figure 2 As shown, the adjustment assembly 22 includes a first sleeve 221 and two fixing components 222 .

[0048] The first sleeve 221 is sleeved on the outside of the shunt pipe 21 , and the two fixing components 222 are respectively provided at both ends of the first sleeve 221 .

[0049] The fixing component 222 includes a plurality of arc-shaped fins 2221 , a sealing ring 2223 and a tightening sleeve 2224 .

[0050] Among them, multiple curved fins 2221 are arranged in a conical structure, one end of the multiple curved fins 2221 is integrally formed, one end of the multiple curved fins 2221 is connected to the first sleeve 221, a groove body 2222 is provided between the two curved fins 2221, the sealing ring 2223 is arranged on the inner side of the multiple curved fins 2221, the tightening sleeve 2224 is sleeved on the outer side of the multiple curved fins 2221, and the tightening sleeve 2224 is threadedly connected to the multiple curved fins 2221.

[0051] Specifically, in the process of adjusting the adjustment component 22, the tightening sleeves 2224 at both ends of the first sleeve 221 are rotated to push the first sleeve 221 so that the first sleeve 221 moves on the surface of the diverter tube 21. After the position of the first sleeve 221 is determined, the tightening sleeves 2224 at both ends of the first sleeve 221 are rotated again. Since the multiple curved fins 2221 are arranged in a conical structure, during the rotation process, the tightening sleeve 2224 is threadedly connected to the curved fins 2221, and the tightening sleeve 2224 squeezes the multiple curved fins 2221. The curved fins 2221 squeeze the sealing ring 2223, thereby fixing the position of the first sleeve 221 and sealing the diverter tube 21 and the first sleeve 221.

[0052] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the inner tube component 332 includes a first inner tube 3321 , a column 3322 , a plurality of balls 3324 and a rubber tube 3325 .

[0053] Among them, the first inner tube 3321 is inserted into the interior of the outer tube 331, one end of the column 3322 is connected to one end of the first inner tube 3321, the column 3322 is located inside the outer tube 331, and a channel 3323 is opened on one side of the column 3322. The diameter of the channel 3323 is smaller than the diameter of the first inner tube 3321. A plurality of balls 3324 are respectively arranged on the outside of the column 3322. The balls 3324 are rollingly connected to the outer tube 331. One end of the rubber tube 3325 is connected to one end of the outer tube 331, and the other end of the rubber tube 3325 is connected to the outer wall of the column 3322.

[0054] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the drip nozzle component 333 includes a limiting member 3331, a pumping rod 3332, a force plate 3333, a blocking plate 3334 and a spring 3335.

[0055] Among them, the limiting member 3331 is connected to the inner wall of the first inner tube 3321, the pulling rod 3332 is slidingly connected to the limiting member 3331, the force plate 3333 is connected to one end of the pulling rod 3332, the force plate 3333 is located on one side of the limiting member 3331, the blocking plate 3334 is connected to the other end of the pulling rod 3332, the blocking plate 3334 is located at the other end of the first inner tube 3321, the diameter of the blocking plate 3334 is larger than the diameter of the first inner tube 3321, and the spring 3335 is sleeved on the outside of the pulling rod 3332.

[0056] In the above embodiment, the force plate 3333 is used to bear the pressure brought by the irrigation water to push the pumping rod 3332 and the blocking plate 3334.

[0057] Specifically, when the external water pressure is relatively low, the irrigation water flows through the channel 3323 and the first inner tube 3321 to reach the drip nozzle part 333. At this time, the pressure on the drip nozzle part 333 is small, the spring 3335 is slightly compressed, and the flow rate of irrigation water discharged from the end of the first inner tube 3321 is relatively small.

[0058] When the external water pressure increases, the deformation of the spring 3335 increases, and the flow rate of the irrigation water discharged through the end of the first inner tube 3321 increases.

[0059] When the external water pressure increases further, the flow rate of irrigation water discharged from the end of the first inner tube 3321 is limited, and the external water pressure increases further. The column 3322 begins to move, and multiple balls 3324 roll on the inner wall of the first inner tube 3321. The rubber tube 3325 is stacked between the outer tube 331 and the first inner tube 3321. The column 3322 pushes the first inner tube 3321 and the drip nozzle component 333 to move. When the rubber tube 3325 is stacked to a certain extent, the balls 3324 are restricted, the column 3322 stops moving, and the length of the branch pipe assembly 33 increases, thereby expanding the irrigation range of the device.

[0060] When irrigation is finished, under the action of spring 3335, blocking plate 3334 closes one end of the first inner tube 3321, and supply device 1 extracts irrigation water from diversion mechanism 2 and drip irrigation mechanism 3. The pressure in branch pipe assembly 33 changes, and column 3322 drives the first inner tube 3321 to reset itself, so as to facilitate the next irrigation.

[0061] In the above embodiment, the blocking plate 3334 and one end of the first inner tube 3321 are not completely closed, and there is a rigid connection between the two. When the column 3322 drives the first inner tube 3321 to reset itself, external air can enter the interior of the first inner tube 3321 to push the column 3322 to move.

[0062] It should be noted that, since the rubber tube 3325 is stacked between the outer tube 331 and the first inner tube 3321 , the first inner tube 3321 will not separate from the outer tube 331 during the movement.

[0063] In one embodiment of the present application, Figure 1 and Figure 4 As shown, a rotary connection seat 41 is provided between the adjustment assembly 22 and the drip irrigation mechanism 3 .

[0064] It should be noted that the specific structure of the rotating connecting seat 41 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here. It can ensure the sealing between the two while ensuring the rotation.

[0065] It is understandable that the provision of the rotary connection seat 41 can reverse the position of the drip irrigation mechanism 3, thereby further improving the irrigation range of the drip irrigation equipment.

[0066] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the end of the drip irrigation mechanism 3 and the end of the diversion pipe 21 are respectively provided with a blocking cover 42.

[0067] It is understandable that the blocking cover 42 is threadedly connected to the end of the drip irrigation mechanism 3 and the end of the diversion pipe 21 respectively, so that when blockage occurs in the subsequent water channel, it is convenient for relevant personnel to repair the drip irrigation equipment.

[0068] In one embodiment of the present application, Figure 3 As shown, the through hole 210 is located on the side opposite to the drip irrigation mechanism 3 .

[0069] It should be noted that setting the through hole 210 on the opposite side of the drip irrigation mechanism 3 can enable the irrigation water to enter the interior of the first sleeve 221 first, and the irrigation water hitting the inner wall of the first sleeve 221 can form a mixing effect. This solution is suitable for the step of using this drip irrigation equipment to apply medicine during the seedling cultivation process.

[0070] In one embodiment of the present application, Figure 8 As shown, the supply device 1 includes a box body 11, a DC brushless water pump 12, a third pipe body 13 and a water supply pipe 14.

[0071] Among them, the DC brushless water pump 12 is arranged inside the box body 11, one end of the third tube body 13 is connected to the DC brushless water pump 12, the other end of the third tube body 13 is connected to the shunt pipe 21, and one end of the water supply pipe 14 passes through the outer wall of the box body 11.

[0072] It should be noted that the other end of the water supply pipe 14 in this embodiment is connected to an external water source.

[0073] In the above embodiment, the DC brushless water pump 12 can be freely controlled to rotate forward or reverse by an external device, thereby injecting or pumping water into the drip irrigation mechanism 3 .

[0074] In summary, the seedling planting drip irrigation equipment of the embodiment of the present application can adjust the position of the drip irrigation mechanism according to the specific usage scenario, and then inject or pump water into the irrigation pipeline through a DC brushless water pump, so that the branch pipe assembly can automatically extend and shorten, thereby expanding the drip irrigation range and meeting diverse planting needs.
