[0053] S4. The motor of the stirring assembly drives the stirring roller to rotate to mix the water flow and the medicine or fertilizer, and simultaneously clean the inner wall of the middle tube.

[0054] S5, water flows through the outlet trough into the irrigation pipeline and flows out through the through hole, thereby achieving irrigation;

[0055] During irrigation, the water flow is increased to push the telescopic tube to stretch, thereby driving the sliding tube to correspond to different through holes, or the sliding tube is driven to move by pulling cables;

[0056] Among them, at the end of irrigation, the passage between the three-way pipe and the water supply unit is cut off by the switch valve, and then the air compressor unit performs suction, forming negative pressure in the telescopic pipe, driving the sliding pipe to move back and reset.

[0057] The multi-channel water-fertilizer integrated irrigation unit and its application method of the present invention have the following beneficial effects compared with the prior art:

[0058] (1) By setting up a water supply unit, it can transport water to the mixing component. The irrigation pipeline is provided with a plurality of through holes, so the through holes can be matched to the plant culture tray. In addition to supplying irrigation water, the water supply unit also controls the displacement of the mixing component, so that the matching of the mixing component and the through holes can be achieved, thereby achieving precise irrigation of plants, making full use of water resources and reducing waste; after the irrigation is completed, negative pressure is generated by the air compressor unit to drive the mixing component to reset; at the same time, drugs or fertilizers can be supplied to the mixing component by adding components to mix the water flow, thereby preventing and controlling plant diseases and supplying nutrients;

[0059] (2) A telescopic tube and a sliding tube are provided in the mixed delivery component. When water is supplied into the telescopic tube, as the water pressure increases, the telescopic tube will extend, thereby driving the sliding tube to move. Then, the water outlet of the sliding tube will correspond to the through hole of the irrigation pipeline to achieve precise irrigation. After the irrigation is completed, the air compressor unit generates negative pressure, and the telescopic tube retracts, thereby driving the sliding tube to reset.

[0060] (3) The sliding tube includes an end tube, an intermediate tube, an end plate, a ring plate and a sealing ring. When the sliding tube slides inside the irrigation pipeline, the sealing ring on the ring plate and the end plate can be used to hold the inner wall of the irrigation pipeline, thereby achieving partial sealing. In this way, after the water flows out through the water outlet groove on the intermediate tube, it will only flow out through the through hole located between the two sealing rings, thereby achieving precise irrigation and avoiding waste problems;

[0061] (4) A fixing plate and a fixing screw are provided on the sliding tube, which facilitates the connection and fixing of the end plate and the middle tube, and is also convenient for subsequent removal, thereby improving the convenience of cleaning and maintenance in case of blockage; at the same time, a heating pipe is provided corresponding to the water outlet, which can heat the water flowing out of the water outlet in the irrigation pipeline to meet the irrigation needs of the plants, thereby preventing the water flow temperature from being too low and affecting the growth of the plants; the fixing screw and the heating pipe are arranged around the middle tube array, thereby improving the convenience of grouping;

[0062] (5) By providing a stirring assembly and a first adding tube, the first adding tube is used as an adding assembly, which can deliver the medicine or fertilizer into the middle tube, and then the stirring roller is driven by the motor of the stirring assembly to rotate, so that the water flow and the medicine / fertilizer can be fully mixed, thereby meeting the growth needs of the plants; by providing a one-way valve, the mixed water flow can be prevented from flowing into the telescopic tube, thereby ensuring that there is no sedimentation problem in the telescopic tube, so that when cleaning later, only the sliding tube needs to be cleaned;

[0063] (6) The telescopic tube is composed of a corrugated section, a percolation tube and a second addition tube. Thus, the second addition tube can be used to add medicine or fertilizer into the percolation tube, so that the medicine or fertilizer is mixed in the telescopic tube and then output through the middle tube of the sliding tube. Since a one-way valve and a first addition tube are provided, the second addition tube is only used as a mixing pipeline for medicine or only as a mixing pipeline for fertilizer, so as to avoid the existence of residues and the subsequent mixing reaction of medicine and fertilizer. When cleaning, only the sliding tube needs to be cleaned, which improves the convenience of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] like Figures 1 to 12 As shown, the multi-channel water-fertilizer integrated irrigation unit of the present invention includes a water supply unit 1, an air compressor unit 2, an irrigation pipeline 3, a three-way pipe 4, a mixing component 5 and an adding component.

[0080] like Figures 1 to 6 As shown, the water outlet of the water supply unit 1, the air inlet of the air compressor unit 2 and the water inlet of the irrigation pipeline 3 are each connected to a port of the tee pipe 4, and the water outlet of the water supply unit 1 and the air inlet of the air compressor unit 2 are both installed with a switch valve; the irrigation pipeline 3 is axially provided with a plurality of through holes 301; the mixing component 5 is slidably arranged in the irrigation pipeline 3 to selectively output water flow corresponding to the through holes 301; when the water supply unit 1 supplies water to the irrigation pipeline 3, the water outlet end of the mixing component 5 is controlled to be away from the tee pipe 4;

[0081] As in the above structure, when the irrigation unit is arranged, the through hole 301 of the irrigation pipeline 3 corresponds to the culture tray or other container for carrying plants;

[0082] When working, firstly, the passage between the air compressor unit 2 and the three-way pipe 4 is cut off by the switch valve, and then the water supply unit 1 supplies water into the mixing component 5, and then the water flows out through the mixing component 5 and outputs through the through hole 301 of the irrigation pipeline 3, so as to irrigate the corresponding culture tray;

[0083] The mixing assembly 5 is slidably disposed in the irrigation pipeline 3, and by increasing the water pressure, the mixing assembly 5 can be moved while carrying out water irrigation to correspond to different through holes 301;

[0084] Specifically, after the culture tray corresponding to the first through hole 301 is irrigated, the water flow is increased and the water pressure is increased to move the mixing component 5 to the corresponding through hole 301 at the back, and the water flow is reduced and the water pressure is lowered to keep the mixing component 5 in place. After the corresponding through hole 301 is irrigated, the above steps are repeated to irrigate the culture tray at the back. This achieves the effect of precise irrigation, effectively saves water resources, avoids water waste, and at the same time, each culture tray is irrigated with the same amount of water, so there will be no problem of uneven water flow distribution.

[0085] Furthermore, when the air compressor unit 2 is exhausting air, the water outlet end of the mixing component 5 is controlled to be close to the three-way pipe 4; the adding component is used to supply medicine or fertilizer into the mixing component 5;

[0086] As in the above structure, the water supply unit 1 is used to supply irrigation water and also to drive the mixing and transporting assembly 5 to move, while the air compressor unit 2 is used to drive the mixing and transporting assembly 5 to reset.

[0087] Specifically, when the air compressor unit 2 is working, it draws air to generate negative pressure, and then attracts the mixed delivery component 5 to move back and reset;

[0088] The adding component is used to supply medicine or fertilizer into the mixing component 5, so as to prevent and control plant diseases and supply nutrients.

[0089] In some embodiments, the air compressor unit 2 performs blowing to deliver water mist carrying medicines and fertilizers, which can meet the needs of plant leaf disease prevention and control and foliar fertilizer application, thereby achieving multi-purpose use.

[0090] like Figure 3 and Figure 4As shown, the mixed delivery assembly 5 includes a telescopic tube 51 and a sliding tube 52, wherein one end of the telescopic tube 51 is connected to the same pipe opening of the tee pipe 4 of the irrigation pipeline 3 to form a coaxial structure; the sliding tube 52 is connected to the other end of the telescopic tube 51, and the end of the sliding tube 52 away from the telescopic tube 51 is a sealing structure, and a water outlet groove 501 is provided on the circumferential surface of the sliding tube 52;

[0091] As described above, the mixed delivery assembly 5 is composed of a telescopic tube 51 and a sliding tube 52. When the water supply unit 1 supplies water, water flows through the telescopic tube 51 into the sliding tube 52, and then flows out through the water outlet 501, and then irrigates through the through hole 301;

[0092] When the water supply unit 1 increases the water flow, as the water pressure increases, the telescopic tube 51 will be driven to extend, so that the water outlet end of the sliding tube 52 can move in the irrigation pipeline 3 to reach other through holes 301; when the air compressor unit 2 is exhausting air, the telescopic tube 51 will retract, thereby driving the sliding tube 52 to return to its original position, thereby meeting the irrigation needs. It has the advantages of simple structure and convenient adjustment.

[0093] like Figure 4 and Fig.11 As shown, the sliding tube 52 includes an end tube 521, an intermediate tube 522, an end plate 523, a ring plate 524 and a sealing ring 525, wherein one end of the end tube 521 is connected to one end of the telescopic tube 51 away from the tee tube 4, and the other end of the end tube 521 is connected to the intermediate tube 522; the water outlet 501 is provided on the circumference of the intermediate tube 522; the end plate 523 seals one end of the intermediate tube 522 away from the end tube 521; the ring plate 524 is provided on the end tube 521; and the sealing ring 525 is provided on the circumference of the end plate 523 and the ring plate 524, respectively, and abuts against the inner wall of the irrigation pipeline 3;

[0094] As described above, the sliding tube 52 includes an end tube 521, an intermediate tube 522, an end plate 523, a ring plate 524 and a sealing ring 525; wherein the end tube 521 is used to connect with the telescopic tube 51 to introduce water flow into the intermediate tube 522, and the other end of the intermediate tube 522 is sealed by the end plate 523 to prevent water flow from overflowing, so that the water flow can only flow out through the water outlet 501;

[0095] Among them, sealing rings 525 are arranged on the circumferential surfaces of the end plate 523 and the ring plate 524 to abut against the inner wall of the irrigation pipe 3, so that the water flowing out through the water outlet trough 501 will only flow out through the through hole 301 located between the two sealing rings 525. Through the targeted setting of this structure, precise irrigation can be achieved to avoid the problem of waste.

[0096] like Figure 4 , Figures 9-11As shown, the sliding tube 52 further includes a fixing plate 526, a heating tube 527 and a fixing screw 528, wherein the water outlet groove 501 is based on the axis of the intermediate tube 522, and a plurality of fixing plates 526 are arranged in an array on the circumference of the intermediate tube 522; a plurality of fixing plates 526 are arranged on the circumference of the intermediate tube 522, and correspond to the water outlet grooves 501; the heating tube 527 and the fixing screw 528 are arranged corresponding to the water outlet grooves 501, and one end of the heating tube 527 and the fixing screw 528 is connected to the fixing plate 526, and the other end is connected to the end plate 523;

[0097] As in the above structure, a fixing plate 526 is provided on the middle tube 522, so that the end plate 523 can be connected to the fixing plate 526 through a fixing screw 528, thereby realizing the integration of the end plate 523 and the middle tube 522. This structure is also convenient for disassembly and assembly, which is conducive to later cleaning and maintenance work to avoid clogging problems;

[0098] Meanwhile, a plurality of water outlet grooves 501 are arranged on the middle tube 522, and the fixing screws 528 and the heating tubes 527 are arranged at intervals and around the middle tube 522. After the water flows out through the water outlet grooves 501, the water flowing out of the water outlet grooves 501 can be heated in the irrigation pipeline 3 through the heating tubes 527 to meet the irrigation needs of the plants, thereby preventing the water flow temperature from being too low to affect the growth of the plants, and ensuring that the plants can carry out normal photosynthesis and transpiration.

[0099] This structure has the advantage of being easy to group and integrate; specifically, the portion of the intermediate tube 522 corresponding to the fixed screw 528 may not be provided with the water outlet trough 501.

[0100] like Figure 4 , Figure 8 and Fig.12 As shown, the mixed transmission assembly 5 also includes a power supply connection 53, a ring frame 54 and a cable 55, wherein the end plate 523 is an integrated circuit board to supply power to the heating tube 527; the power supply connection 53 is electrically connected to the circuit board in the end plate 523; the ring frame 54 is arranged on a side of the end plate 523 away from the middle tube 522; one end of the cable 55 is connected to the ring frame 54, and the other end extends to the outside of the irrigation pipeline 3;

[0101] As shown in the above structure, the mixed transmission component 5 is provided with a power supply connection 53. Since the heating tube 527 is integrated between the end plate 523 and the ring plate 524, the control circuit board can be integrated in the end plate 523. When the heating tube 527 is in contact with the end plate 523, the heating tube 527 is electrically connected to the circuit board and the power supply connection 53 at the same time, so as to facilitate the power supply to the heating tube 527.

[0102] Furthermore, a ring frame 54 is provided on the end plate 523 for connecting the cable 55, so that the cable 55 can be used to drive the water outlet end of the mixing assembly 5 to move. At this time, there is no need to increase the water flow to push the mixing assembly 5 to move, which is more conducive to accurately controlling the irrigation water volume.

[0103] like Figure 4 As shown, the mixing assembly 5 further includes a stirring assembly 56 and a first adding pipe 57, wherein the stirring assembly 56 includes a motor 561 and a stirring roller 562, wherein the motor 561 is arranged on the side of the end plate 523, and the output shaft of the motor 561 passes through the end plate 523, and the ring frame 54 surrounds the motor 561; the stirring roller 562 is connected to the output shaft of the motor 561, and the stirring roller 562 is located in the middle pipe 522; the first adding pipe 57 is located in the ring frame 54, and one end of the first adding pipe 57 is connected to the end plate 523 and communicated with the middle pipe 522;

[0104] As in the above structure, the first adding pipe 57 is an adding component. When the sliding pipe 52 is supplied with water, when the water flows through the telescopic pipe 51 and enters the sliding pipe 52, the medicine or fertilizer is simultaneously fed into the sliding pipe 52 through the first adding pipe 57, so as to realize two-way supply.

[0105] At the same time, the motor 561 of the stirring assembly 56 is activated to drive the stirring roller 562 to rotate in the middle tube 522 of the sliding tube 52, thereby achieving uniform mixing of the water flow and the medicine / fertilizer to better apply to the plants, thereby meeting the growth requirements of the crop plants;

[0106] Specifically, when this structure is arranged, the motor 561 and the first adding pipe 57 are arranged in the ring frame 54, so as to make full use of the side space of the end plate 523, ensure its compactness, and avoid the convenience of use affected by excessive volume;

[0107] Specifically, with respect to the structure of the stirring roller 562, bristles are provided on its circumference to support the inner wall of the middle tube 522 with the bristles. Thus, when mixing and stirring are performed, the inner wall of the middle tube 522 is brushed simultaneously, thereby avoiding crystallization and reducing the probability of blockage.

[0108] like Figure 4 As shown, the mixing and delivery assembly 5 further includes a one-way valve 58, which includes an annular plate 581, a slip ring 582 and a valve flap 583, wherein the annular plate 581 is sleeved on the end of the stirring roller 562; a slip ring 582 is provided on both the inner and outer annular surfaces of the annular plate 581, the slip ring 582 on the inner annular surface is slidably matched with the stirring roller 562, and the slip ring 582 on the outer annular surface is slidably matched with the end pipe 521;

[0109] As in the above structure, by setting a one-way valve 58, the mixed water flow can be prevented from flowing into the telescopic tube 51, thereby ensuring that there is no sedimentation problem in the telescopic tube 51. In this way, when cleaning later, only the sliding tube 52 needs to be cleaned, thereby preventing the normal growth of plants from being affected by the residual medicine when applied to different plants;

[0110] Specifically, when the one-way valve 58 is integrated, the two sliding rings 582 are respectively slidably matched with the peripheral surface of the stirring roller 562 and the inner wall of the end tube 521, and the sliding seal is performed;

[0111] Specifically, the one-way valve 58 may also be integrated on the stirring roller 562 or the end pipe 521 .

[0112] like Figure 5 and Figure 7 As shown, the telescopic tube 51 includes a corrugated section 511, a percolation tube 512 and a second addition tube 513, wherein the corrugated section 511 and the percolation tube 512 are staggered with each other; the percolation tube 512 is an annular tube, and the percolation tube 512 has an inner cavity 502, the corrugated section 511 and the inner wall of the percolation tube 512 form a passage 503 of the telescopic tube 51, and the percolation tube 512 can percolate liquid into the passage 503; one end of the second addition tube 513 is connected to the percolation tube 512, and the other end extends to the outside of the irrigation pipeline 3, and the irrigation pipeline 3 is provided with a chute 302 corresponding to the second addition tube 513;

[0113] As described above, for the structure of the telescopic tube 51, it is telescopic through the corrugated section 511, and the addition work is achieved through the percolation tube 512, wherein the passage 503 is the inner cavity of the telescopic tube 51;

[0114] Specifically, as the water pressure increases or negative pressure is attracted, the bellows section 511 achieves a telescopic action, thereby causing the sliding tube 52 to move;

[0115] During specific operation, the infiltration tube 512 has a separate inner cavity 502, and the second addition tube 513 is an addition component. The medicine or fertilizer is fed into the inner cavity 502 of the infiltration tube 512 through the second addition tube 513, and the supply pressure is appropriately increased, so that the medicine or fertilizer seeps out through the infiltration tube 512 and enters the passage 503 from the inner cavity 502. In this way, the water flow and the medicine / fertilizer can be mixed in the telescopic tube 51, thereby meeting the growth requirements of the plants;

[0116] In this structure, in order to avoid interference with the extension and contraction of the telescopic tube 51, the irrigation pipeline 3 is provided with a slide groove 302 for the second adding tube 513 to slide; in order to avoid water leakage in the slide groove 302 during irrigation, the slide groove 302 is opened upward;

[0117] In this structure, since the one-way valve 58 is provided, the second addition pipe 513 can be used only as a mixing pipe for the agent or only as a mixing pipe for the fertilizer, and the other additive is supplied through the first addition pipe 57 to avoid the problem of residue and subsequent mixing reaction of the agent and the fertilizer.

[0118] In this way, only the sliding tube 52 needs to be cleaned during cleaning, thereby improving the convenience of maintenance.

[0119] In some embodiments, the second adding tube 513 is connected via a linear displacement component to drive the mixing component 5 to reset.

[0120] like Figure 7 As shown, the filtration tube 512 includes a ring tube 5121, a filtration membrane 5122 and a scraper ring 5123, wherein the ring tube 5121 is a ring-shaped structure, and the cross section of the ring tube 5121 is U-shaped, with the opening facing inward; the filtration membrane 5122 is arranged on the inner side of the ring tube 5121 to cooperate to form an inner cavity 502; the scraper ring 5123 is arranged on both sides of the ring tube 5121 and abuts against the inner wall of the irrigation pipeline 3; the second addition tube 513 is connected to the ring tube 5121;

[0121] As in the above structure, the annular tube 5121 is configured as an annular structure with a U-shaped cross section, so that after the medicine or fertilizer is fed into the inner cavity 502, it can be supplied into the passage 503 through the percolation membrane 5122 to achieve mixing with the water flow;

[0122] The ring tube 5121 is configured as a rigid structure. When the telescopic tube 51 is extended or retracted, the ring tube 5121 only performs sliding displacement and does not deform. This can prevent the filtration membrane 5122 from deforming, thereby ensuring the stability of the application.

[0123] Furthermore, scraper rings 5123 are provided on both sides of the ring tube 5121. When the corrugated section 511 drives the infiltration tube 512 to move, the scraper rings 5123 can scrape the inner wall of the irrigation pipeline 3 to remove water flow sediments, thereby avoiding subsequent influence on the normal displacement of the mixing component 5, thereby ensuring stable application.

[0124] The method of applying the above-mentioned multi-channel water-fertilizer integrated irrigation unit of the present invention comprises the following steps:

[0125] S1, cut off the passage between the three-way pipe 4 and the air compressor unit 2 through the switch valve;

[0126] S2, water is fed into the telescopic pipe 51 of the mixing assembly 5 through the water supply unit 1, and the water flows into the sliding pipe 52 through the one-way valve 58,

[0127] S3, supply medicine or fertilizer into the sliding tube 52 through the first adding tube 57,

[0128] S4, the motor 561 of the stirring assembly 56 drives the stirring roller 562 to rotate to mix the water flow and the medicine or fertilizer, and simultaneously clean the inner wall of the middle tube 522,

[0129] S5, water flows through the water outlet trough 501 into the irrigation pipeline 3, and flows out through the through hole 301, thereby achieving irrigation;

[0130] During irrigation, the water flow is increased to push the telescopic tube 51 to stretch, thereby driving the sliding tube 52 to correspond to different through holes 301, or the cable 55 is pulled to drive the sliding tube 52 to move;

[0131] When irrigation is finished, the passage between the three-way pipe 4 and the water supply unit 1 is cut off by the switch valve, and then the air compressor unit 2 performs suction, and negative pressure is formed in the telescopic tube 51, driving the sliding tube 52 to move back and reset.

[0132] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
