Description

Technical Field

[0001] The invention belongs to the field of irrigation equipment, and in particular relates to vegetable greenhouse water and fertilizer irrigation equipment and a vegetable greenhouse water and fertilizer irrigation system. Background Art

[0002] Water-fertilizer is an agricultural technology that combines water and fertilizer, and is usually used for irrigation and fertilization at the same time. The composition of water-fertilizer can be adjusted according to different needs and crop types, but usually includes nitrogen sources (urea, ammonium nitrate, etc.), phosphorus sources (potassium dihydrogen phosphate, monoammonium phosphate, etc.), potassium sources (potassium sulfate, potassium chloride, etc.), trace elements (iron, zinc, copper, manganese, boron, etc.) and organic substances (humic acid, amino acids, etc.). Therefore, long-term use can easily cause dried fertilizers to accumulate at the drainage port of the sprinkler. In order to ensure that the fertilizer is evenly distributed and effectively absorbed by the plants, it is usually necessary to use drip irrigation, sprinkler irrigation, etc. Precision irrigation leads to a small flow of water and fertilizer at the sprinkler during the use of water-fertilizer, and long-term use can easily cause the drainage port to be blocked.

[0029] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] Water-fertilizer is an agricultural technology that combines water and fertilizer, and is usually used for irrigation and fertilization at the same time. The composition of water-fertilizer can be adjusted according to different needs and crop types, but usually includes nitrogen sources (urea, ammonium nitrate, etc.), phosphorus sources (potassium dihydrogen phosphate, monoammonium phosphate, etc.), potassium sources (potassium sulfate, potassium chloride, etc.), trace elements (iron, zinc, copper, manganese, boron, etc.) and organic matter (humic acid, amino acids, etc.). Therefore, long-term use can easily cause dried fertilizer to accumulate at the drainage port of the sprinkler. In order to ensure that the fertilizer is evenly distributed and effectively absorbed by the plants, it is usually necessary to use drip irrigation, sprinkler irrigation and other precise irrigation. As a result, the flow rate of water and fertilizer at the sprinkler during the use of water-fertilizer will not be large, and long-term use can easily cause the drainage port to be blocked.

[0034] In order to solve the above technical problems, refer to Figure 1-Figure 10 The embodiment of the present application provides a vegetable greenhouse water and fertilizer irrigation device including a connecting pipe 1, a watering head 2, a floating member 3 and a dredging component 4. One end of the connecting pipe 1 is connected to a water and fertilizer source; a buffer cavity 211 having a liquid discharge port 212 is formed inside the watering head 2; the floating member 3 is disposed in the buffer cavity 211; the dredging component 4 is disposed below the liquid discharge port 212 and connected to the floating member 3. The floating member 3 is driven by the water and fertilizer to move away from the liquid discharge port 212 along the gravity direction X, so as to drive part of the dredging component 4 to enter the buffer cavity 211 through the liquid discharge port 212 along the gravity direction X.

[0035] The connecting pipe 1 may be a corrugated pipe, so that when the watering head 2 moves, it can be extended or shortened to adapt to the distance between the watering head 2 and the water fertilizer source. The water fertilizer source may be a tank with a liquid pump, and the water fertilizer liquid is stored in the tank.

[0036] In some embodiments, the floating member 3 is a floating ball with a hollow structure. The vegetable greenhouse water and fertilizer irrigation equipment may further include a guide rod, one end of which is connected to the floating member 3, and the other end of which passes through the irrigation head 2 along the gravity direction X and is connected to the dredging component 4. So that the floating member 3 can drive the dredging component 4 to move along the gravity direction X, it can be understood that the guide rod and the irrigation head 2 are sealed by a sealing member.

[0037] In some embodiments, a partition 21 extending along the gravity direction X is disposed inside the buffer chamber 211, and the partition 21 is used to separate the buffer chamber 211 into a first sub-chamber 211A and a second sub-chamber 211B arranged along the second direction Z and interconnected, wherein the drain port 212 is connected to the first sub-chamber 211A, and the float 3 is disposed in the second sub-chamber 211B.

[0038] Specifically, during normal use, the buffer chamber 211 buffers the water-fertilizer solution discharged from the connecting pipe 1 to reduce the flow rate of the water-fertilizer solution, thereby allowing the water-fertilizer solution to accurately drip or sprinkle irrigate the crops through the discharge port 212 .

[0039] When the dried fertilizer blocks the drain port 212, the liquid level of the water-fertilizer solution in the buffer chamber 211 rises, thereby driving the floating member 3 to move away from the drain port 212, and then the floating member 3 overcomes the gravity of the dredging component 4, driving the dredging component 4 to move toward the drain port 212, and then the dredging component 4 penetrates the dried fertilizer and dredges the drain port 212, so that the water-fertilizer can flow out of the drain port 212 normally, and then the liquid level in the buffer chamber 211 is lowered, and then the floating member 3 moves toward the drain port 212 to reset, and the dredging component 4 resets under the action of gravity. In this way, the blocked drain port 212 can be cleaned regularly.

[0040] According to some embodiments of the present application, the vegetable greenhouse water and fertilizer irrigation equipment also includes a mounting plate 5 and a driving member 6. The mounting plate 5 is arranged below the irrigation head 2 and is located on one side of the drainage port 212 in the first direction Y. The dredging component 4 can be slidably arranged on the mounting plate 5 along the gravity direction X. The first direction Y is perpendicular to the gravity direction X. The driving member 6 is bent, and the driving member 6 includes a driving portion 61 extending along the gravity direction X and an abutting portion 62 extending along the second direction Z. The driving member 6 can be slidably arranged on the mounting plate 5 along the gravity direction X. The driving member 6 is connected to the floating member 3, and the abutting portion 62 abuts against the dredging component 4 along the gravity direction X to drive the dredging component 4 to move toward the direction close to the drainage port 212. The first direction Y, the second direction Z and the gravity direction X are perpendicular to each other.

[0041] In some embodiments, the driving member 6 can be slidably disposed on the mounting plate 5 via a guide rail or other structure, and can move along the gravity direction X relative to the mounting plate 5 .

[0042] In some embodiments, the driving member 6 is connected to the floating member 3 located in the buffer cavity 211 through the second connecting rope 31. The second connecting rope 31 can be a nylon rope, one end of the second connecting rope 31 is connected to the driving member 6, and the other end of the second connecting rope 31 passes through the wall of the buffer cavity 211 and is connected to the floating member 3. It can be understood that the gap between the second connecting rope 31 and the wall of the buffer cavity 211 is sealed by a sealing member.

[0043] In the above technical solution, the driving member 6 and the dredging component 4 are slidably installed below the drain port 212 through the mounting plate 5, so that the dredging component 4 and the floating member 3 are connected through the driving member 6, and the structure is simple and easy to implement.

[0044] According to some embodiments of the present application, the side of the mounting plate 5 facing the driving member 6 has a slide groove 51, and the slide groove 51 has a first section 511 extending along the second direction Z; the clearing component 4 includes a slider 43 arranged in the slide groove 51; the driving part 61 is provided with a first guide surface 611 on the side facing the clearing component 4 in the second direction Z, and the first guide surface 611 moves relative to the clearing component 4 along the gravity direction X to guide the clearing component 4 to move along the first section 511 and make the clearing component 4 directly below the drain port 212.

[0045] It can be understood that the slide groove 51 can be a dovetail groove, and the slider 43 can be a dovetail block adapted to the dovetail groove.

[0046] Specifically, when the dried fertilizer does not block the drain outlet 212 , the dredging component 4 is located on one side of the drain outlet 212 in the second direction Z, thereby reducing the risk of the dredging component 4 interfering with the water fertilizer solution flowing out of the drain outlet 212 .

[0047] When the dried fertilizer blocks the drain port 212, the liquid level of the water-fertilizer solution in the buffer chamber 211 rises, thereby driving the floating member 3 to move away from the drain port 212, so that the floating member 3 overcomes the gravity of the driving member 6, driving the driving member 6 to approach the drain port 212 along the gravity direction X, and then the first guide surface 611 moves relative to the dredging component 4 along the gravity direction X to guide the dredging component 4 to move along the first section 511, so that the dredging component 4 is located directly below the drain port 212. Then, the abutting portion 62 abuts against the dredging component 4 to drive the dredging component 4 to penetrate the dried fertilizer and dredge the drain port 212, so that the water-fertilizer can flow out of the drain port 212 normally.

[0048] According to some embodiments of the present application, the clearing component 4 also includes a mounting sleeve 41 and a rotating shaft 42, and a slider 43 is arranged on the outside of the mounting sleeve 41; the middle part of the rotating shaft 42 can be slidably inserted in the mounting sleeve 41 along the gravity direction X, and the abutment portion 62 abuts against one end of the rotating shaft 42 away from the drain port 212 to drive the other end of the rotating shaft 42 to enter the drain port 212.

[0049] Exemplarily, the mounting sleeve 41 has a mounting hole 411 for the rotating shaft 42 to pass through, and the axial direction of the mounting hole 411 is parallel to the gravity direction X.

[0050] In the above technical solution, by setting the clearing component 4 as a split structure of the mounting sleeve 41 and the rotating shaft 42, it is satisfied that while the first guide surface 611 can guide the clearing component 4 to move along the first section 511, the abutment portion 62 can drive part of the clearing component 4 to be inserted into the drain port 212 along the gravity direction X. The structure is simple and easy to implement.

[0051] According to some embodiments of the present application, the installation sleeve 41 has a second guide surface 413 corresponding to the first guide surface 611 on a side facing the driving portion 61 in the second direction Z.

[0052] In the above technical solution, the mounting sleeve 41 has a second guide surface 413 corresponding to the first guide surface 611 on the side facing the driving part 61 in the second direction Z, so that the mounting sleeve 41 is in surface contact with the first guide surface 611, thereby reducing the wear of the mounting sleeve 41 when the mounting sleeve 41 slides relative to the first guide surface 611, thereby extending the service life of the device.

[0053] According to some embodiments of the present application, the mounting sleeve 41 is a hollow structure having an opening 412 , and the opening 412 is arranged on the side of the mounting sleeve 41 facing the drain port 212 ; the clearing component 4 also includes an elastic membrane 44 , which is sleeved on the outside of the rotating shaft 42 and covers the opening 412 .

[0054] The elastic membrane 44 may be a rubber membrane. In some embodiments, a slot may be provided on the outer periphery of the rotating shaft 42, and a portion of the elastic membrane 44 is sleeved outside the rotating shaft 42 and is clamped in the slot 422, and the outer periphery of the elastic membrane 44 is connected to the mounting sleeve 41 by hot melt.

[0055] In the above technical solution, the mounting sleeve 41 is a hollow structure with an opening 412, thereby reducing the overall weight of the dredging assembly 4, so that the driving part 61 can more easily drive the dredging assembly 4 to move. The elastic membrane 44 is sleeved outside the rotating shaft 42 and covers the opening 412. On the one hand, the rotating shaft 42 and the mounting sleeve 41 are elastically connected through the elastic membrane 44, so that after the abutting part 62 no longer abuts against the rotating shaft 42, the elastic membrane 44 can elastically recover to drive the rotating shaft 42 and the mounting sleeve 41 to move toward each other, so that one of the rotating shaft 42 and the mounting sleeve 41 is reset relative to the other.

[0056] According to some embodiments of the present application, a spiral groove 421 is provided on the outer periphery of the rotating shaft 42; the clearing component 4 also includes a boss 45 and a spiral blade 46; the boss 45 protrudes from the inner wall of the mounting sleeve 41 and is located in the spiral groove 421; the spiral blade 46 is wound around one end of the rotating shaft 42 away from the abutment portion 62 in the gravity direction X.

[0057] Specifically, when one of the rotating shaft 42 and the mounting sleeve 41 moves relative to the other in the gravity direction X, the boss 45 will slide relative to the spiral groove 421, thereby driving the rotating shaft 42 and the spiral blade 46 outside the rotating shaft 42 to rotate, thereby facilitating the rotating shaft 42 to penetrate the dried fertilizer and clear the drainage port 212.

[0058] According to some embodiments of the present application, the chute 51 has a second section 512 connected to the first section 511, the second section 512 extends along the gravity direction X, and is bent with the first section 511, along the gravity direction X, the second section 512 is located between the first section 511 and the drain port 212; the first section 511 includes a first subsection 5111 and a second subsection 5112, along the second direction Z, the second subsection 5112 is located between the first subsection 5111 and the second section 512: the first guide surface includes a first subsection Surface 611A and the second sub-guide surface 611B are located along the gravity direction X, and the second sub-guide surface 611B is located between the first sub-guide surface 611A and the abutment portion 62. The first sub-guide surface 611A is used to guide the dredging component 4 to move along the first sub-segment 5111 to the second sub-segment 5112 before the abutment portion 62 abuts against the rotating shaft 42. The second sub-guide surface 611B is used to guide the dredging component 4 to move along the second sub-segment 5112 to the second segment 512 after the abutment portion 62 abuts against the rotating shaft 42.

[0059] Specifically, when the dried fertilizer blocks the drain port 212, the liquid level of the water fertilizer solution in the buffer chamber 211 rises, thereby driving the floating member 3 to move away from the drain port 212, thereby causing the floating member 3 to overcome the gravity of the driving member 6, driving the driving member 6 to approach the drain port 212 along the gravity direction X, thereby causing the first sub-guide surface 611A to move relative to the dredging component 4 along the gravity direction X, so as to guide the dredging component 4 to move along the first sub-segment 5111, so that the rotating shaft 42 is located directly below the drain port 212. Subsequently, the abutting portion 62 abuts against the rotating shaft 42, and since the slider 43 is in the second sub-segment 5112 at this time, the mounting sleeve 41 cannot move along the gravity direction X, thereby causing the rotating shaft 42 to move relative to the mounting sleeve 41 along the gravity direction X and approach the drain port 212, and at this time, the boss 45 slides relative to the spiral groove 421, so that the rotating shaft 42 rotates, so that the rotating shaft 42 can penetrate the dried fertilizer and the elastic membrane 44 is stretched. Then, the second sub-guide surface 611B moves relative to the dredging component 4 along the gravity direction X, so that the slider 43 slides from the second sub-section 5112 into the second section 512, so that the slider 43 of the mounting sleeve 41 can move along the gravity direction X. At this time, the elastic membrane 44 is reset to drive the mounting sleeve 41 to move along the gravity direction X toward the rotating shaft 42, so that the boss 45 slides relative to the spiral groove 421, so that the rotating shaft 42 rotates, and then drives the spiral blade 46 to rotate to drive the dried fertilizer to leave the drain port 212.

[0060] According to some embodiments of the present application, the clearing component 4 also includes a first connecting rope 7; a through hole 52 is provided at the first end of the first sub-segment 5111 away from the second sub-segment 5112, which penetrates the mounting plate 5 along the second direction Z, and the first connecting rope 7 is passed through the through hole 52, and the two ends of the first connecting rope 7 are respectively connected to the driving member 6 and the slider 43.

[0061] Specifically, when the driving member 6 approaches the drain port 212 along the gravity direction X, the first connecting rope 7 is not tightened to facilitate the movement of the slider 43 from the first sub-segment 5111 to the second sub-segment 5112 and the second segment 512; when the driving member 6 moves away from the drain port 212 along the gravity direction X, the first connecting rope 7 is tightened to drive the slider 43 to move from the second segment 512 to the second sub-segment 5112 and the first sub-segment 5111.

[0062] An embodiment of the present application provides a vegetable greenhouse water and fertilizer irrigation system, comprising the vegetable greenhouse water and fertilizer irrigation equipment and a driving mechanism of any of the above embodiments; the driving mechanism is configured to drive the vegetable greenhouse water and fertilizer irrigation equipment to move in a horizontal direction.

[0063] It should be noted that the driving mechanism may be a traveling mechanism arranged in the greenhouse.

[0064] To sum up, the embodiment of the present application provides a vegetable greenhouse water and fertilizer irrigation equipment. When in normal use, the buffer chamber 211 buffers the water and fertilizer solution discharged from the connecting pipe 1 to reduce the flow rate of the water and fertilizer solution, thereby allowing the water and fertilizer solution to accurately drip or sprinkle the crops through the discharge port 212.

[0065] When the dried fertilizer blocks the drain port 212, the liquid level of the water fertilizer solution in the buffer chamber 211 rises, thereby driving the floating member 3 to move away from the drain port 212, so that the floating member 3 overcomes the gravity of the driving member 6 and drives the driving member 6 to approach the drain port 212 along the gravity direction X, so that the first sub-guide surface 611A moves relative to the dredging component 4 along the gravity direction X, so as to guide the dredging component 4 to move along the first sub-section 5111, so that the rotating shaft 42 is located directly below the drain port 212. Then, the abutting portion 62 abuts against the rotating shaft 42, and since the slider 43 is in the second sub-section 5112 at this time, the installation sleeve 41 cannot move along the gravity direction X, so that the rotating shaft 42 moves relative to the installation sleeve 41 along the gravity direction X and approaches the drain port 212, and at this time, the boss 45 slides relative to the spiral groove 421, so that the rotating shaft 42 rotates, so that the rotating shaft 42 penetrates the dried fertilizer and the elastic membrane 44 is stretched. Then, the second sub-guide surface 611B moves relative to the dredging component 4 along the gravity direction X, so that the slider 43 slides from the second sub-section 5112 into the second section 512, so that the slider 43 of the mounting sleeve 41 can move along the gravity direction X. At this time, the elastic membrane 44 is reset to drive the mounting sleeve 41 to move along the gravity direction X toward the rotating shaft 42, so that the boss 45 slides relative to the spiral groove 421, so that the rotating shaft 42 rotates, and then drives the spiral blade 46 to rotate to drive the dried fertilizer to leave the drain port 212. So that the water fertilizer can flow out of the drain port 212 normally, and then the liquid level in the buffer chamber 211 is lowered, and then the floating member 3 moves toward the drain port 212 to reset, so that the driving member 6 is reset along the gravity direction X, so that the abutting portion 62 is no longer abutted with the rotating shaft 42, and then the slider 43 moves along the second section 512 toward the first section 511, and at the same time the first connecting rope 7 is tightened to drive the slider 43 to move toward the first subsection 5111.
