Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation devices, and in particular to an efficient and water-saving agricultural irrigation device and an irrigation method. Background Art

[0002] Agricultural irrigation mainly refers to providing necessary water to farmland through manual or automated equipment to meet the needs of crop growth. Its function is to regulate soil moisture conditions, ensure normal crop growth, and improve land productivity and crop yields. Irrigation is roughly divided into pouring irrigation and drip irrigation. Often after one pouring is completed, drip irrigation can be used before the next pouring according to the crop growth and soil conditions. This alternating method can make full use of the advantages of the two irrigation methods, ensuring sufficient irrigation of farmland and realizing the conservation of water resources.

[0003] The applicant has found that in the process of using sprinkler irrigation in agriculture, the sprinkler head is often fixed, so the crops are generally irrigated continuously. When a certain amount of water is irrigated, the sprinkler irrigation is stopped. However, it takes a certain amount of time for the soil to absorb water. Continuous irrigation will cause water accumulation in the soil, and the excess water will flow away and cause waste. Therefore, the existing improved equipment will design an intermittent irrigation mechanism. For example, patent No. CN109964790A discloses a water-saving agricultural irrigation device, which drives the shaft to rotate through a driving motor, and then the shaft drives the gear to rotate. Under the action of the gear and the arc-shaped tooth plate, the water spray device rotates on the water transport pipe. Since the driving motor is a servo motor, the water spray device will rotate back and forth. When the water spray hole is aligned with the corresponding When the docking holes are docked, the water pipe sprays water, which realizes intermittent water spraying by the water spraying device, avoids water accumulation on the ground, and saves water. However, in the above scheme, intermittent water spraying is achieved by repeated driving of the motor, which leads to increased power consumption during operation, thereby increasing the cost of irrigation, and the mechanical movement of the gears and arc-shaped tooth plates during operation will also generate vibration force, causing equipment instability. Once the meshing structure is damaged, maintenance is troublesome and the repair cost is too high. Secondly, the above scheme does not have a better filtering device, and some irrigation will extract water from the river for storage and use, which makes the nozzle easy to get blocked. Finally, the above scheme is only a single sprinkler irrigation without an additional drip irrigation structure, resulting in insufficient functionality.

[0004] Therefore, the inventor particularly needs to design an efficient and water-saving agricultural irrigation device and irrigation method to solve the above technical problems. Summary of the invention

The water flows into the main horizontal pipe, fixed pipe, telescopic pipe and water inlet pipe and flows to the water guide plate.

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] like Figure 1-Figure 12As shown, an efficient water-saving agricultural irrigation device and irrigation method of the present invention include a water tank 1, one side of the water tank 1 is connected to a water pump 11, the water delivery pipe of the water pump 11 is connected to a main body transverse pipe 13 installed on the inner side of a device seat 12, two rows of L-shaped tubes 14 are penetrated on the top of the device seat 12, and a fine-pore nozzle 15 is provided at the bottom of the L-shaped tube 14, each L-shaped tube 14 in the two rows passes through the bottom of a water guide box 2, two partitions 21 and a V-shaped plate 22 are fixed inside the water guide box 2, the V-shaped plate 22 is fixed on the top of the partition 21, and filter holes are provided on both sides of the V-shaped plate 22 above the L-shaped tube 14 and outside the two partitions 21, a water guide plate 23 is rotatably installed inside the water guide box 2, and the water guide plate 23 alternately fits with the two inclined surfaces of the V-shaped plate 22 by rotation, and a diversion mechanism 3 is installed on the device. The top of the seat 12 includes a fixed tube 31 that is connected to the main body cross tube 13. The fixed tube 31 passes through the device seat 12 and is sealed with a telescopic tube 32 on the outside. The bottom of the telescopic tube 32 is connected to the device seat 12 by a spring 33, and the top of the telescopic tube 32 is connected to a water inlet pipe 34 through a hose. The water outlet of the water inlet pipe 34 passes through the top of the water guide box 2 and is located in the middle of the top of the water guide plate 23. A tooth plate 35 is provided on one side of the telescopic tube 32. The tooth plate 35 is meshed with a gear 36. The gear 36 is connected to the rotating shaft at one end of the water guide plate 23. The two ends of the V-shaped plate 22 are placed on the opening of the side wall of the water guide box 2. The shaft of the water guide box 2 and the gear 36 are connected to the sealing mechanism 4. The sealing mechanism 4 is used to close the opening of the side wall of the water guide box 2. Cleaning mechanisms 5 are installed on both sides of the water guide plate 23 to clean the filter holes of the V-shaped plate 22.

[0025] By designing the diversion mechanism 3, the two sides of the V-shaped plate 22 are butted against the two sides of the inner wall of the water guide box 2, and the partition plate 21 is butted against the two sides and the bottom of the inner wall of the water guide box 2. When the present invention is working, the water guide plate 23 is fitted with an inclined surface of the V-shaped plate 22. When watering, the water pump 11 is started to pump water from the water tank 1, and the water flows into the main body transverse pipe 13, and then into the fixed pipe 31, and then is introduced into the water inlet pipe 34 through the water outlet and the hose at the top of the telescopic pipe 32. The water inlet pipe 34 sprays water to the water guide plate 23, and the inclined water guide plate 2 3 The water is directed to the inclined surface of the V-shaped plate 22, filtered through the filter holes of the inclined surface and flows down to the space formed by the three inner sides of the partition 21, the V-shaped plate 22 and the water guide box 2, so that the water can only be introduced from the entrance of the L-shaped tube 14 in this space, and finally sprayed out by this row of fine-hole nozzles 15 for irrigation. After a period of time, when the irrigation on one side is almost the same, the output frequency of the water pump 11 increases, and the flow rate must be accelerated, so that the telescopic tube 32 overcomes the pulling force of the spring 33 and slides up, so that the tooth plate 35 drives the gear 36 to rotate, and finally makes the water guide plate 23 rotate, and fits with the inclined surface on the other side of the V-shaped plate 22, so that water can be delivered to the L-shaped tube 14 at the other end. After a period of time, the water flow rate is reduced, and the spring 1 33 pulls the telescopic tube 32 to reset and switch back and forth. In this way, the output frequency of the water pump 11 can be used to drive the water guide plate 23 to flip to complete intermittent irrigation at different positions, without the need for motor drive, and the noise is smaller. At the same time, filtering can be performed to avoid clogging of the nozzle or drip irrigation head 24, which has a very good improvement effect. It should be noted that the telescopic tube 32 cannot rotate, and its sealed telescopic structure with the fixed tube 31 is a prior art means, and when the water flow frequency is normal, the water is half the height inside the L-shaped tube 14. When the water flow frequency increases, the L-shaped tube 14 is filled, and the water level inside the water guide box 2 will rise, but this does not affect the water outlet speed of the fine-pore nozzle 15. At the same time, the device can be arranged and used, and a supporting frame can be installed at the end of the L-shaped tube 14, which is not limited here, and the water in the water tank 1 needs to be replenished regularly.

[0026] A rectangular opening is provided on a partition 21, and the height of the rectangular opening is lower than the bottom ends of the two inclined surfaces of the V-shaped plate 22. A T-shaped tube 210 is installed at the bottom end of the water guide box 2, and a row of drip irrigation heads 24 are installed at the bottom ends of the horizontal parts on both sides of the T-shaped tube 210. The vertical part of the T-shaped tube 210 is connected to the water guide box 2 and a solenoid valve 25 is installed on this part. All solenoid valves 25 can be opened and closed uniformly. A row of clamp rings 28 are fixed to the side wall of the L-shaped tube 14, and the clamp ring 28 is connected to the clamps of the horizontal parts on both sides of the T-shaped tube 210. A return water elbow 26 is installed on the side wall of the water guide box 2 between the two partitions 21 and at the bottom end of the V-shaped plate 22. The bottom of the return water elbow 26 is connected to the return water transverse pipe 27 installed on the inner side of the device seat 12, and the return water transverse pipe 27 is connected to the upper end of one side of the water tank 1, and the connection point is above the water level inside the water tank 1.

[0027] By designing the T-tube 210, the drip irrigation head 24 and the solenoid valve 25, a drip irrigation structure is added on the basis of the original irrigation. The specific operation is that when the water flow frequency increases, the water level in the space below the inclined surface where the V-shaped plate 22 guides water will rise, and the rectangular opening on the side partition 21 will introduce water into the space formed by the two partitions 21, the V-shaped plate 22 and the two sides inside the water guide box 2, and the water level in this space will also rise, and will be introduced into the return water horizontal pipe 27 by the return water elbow 26 to return to the water tank 1 for recycling. Then, after each irrigation is completed, the water left in this space can be used for drip irrigation. When drip irrigation is needed after irrigation is completed, the solenoid valve 25 is opened, and the drip irrigation is started. The irrigation water flows into the T-tube 210 and slowly drips through the drip irrigation head 24, and then better maintains the moisture in the crop soil before the next irrigation begins. In terms of design, when the next irrigation begins, the stored water between the two partitions 21 is just used up, thus achieving the coordinated operation of drip irrigation, making the irrigation device more comprehensive in function, and the clamp ring 28 stably connects the L-tube 14 and the T-tube 210 together to enhance stability. It should be noted that the timed automatic opening and closing of the water pump 11 and the solenoid valve 25 and the automatic frequency adjustment of the water pump 11 can all be achieved through the existing intelligent control system, which is not limited or elaborated here.

[0028] The top of the opening on both sides of the water guide box 2 is provided with a recess 46, and the sealing plate mechanism 4 includes a sealing plate 41 sliding in the recess 46 at the upper end of the opening of the water guide box 2, and the pull rope 43 on the top of the sealing plate 41 passes through the water guide box 2, and the pull rope 43 passes through the recess 46 and the top of the water guide box 2, and the pull rope 43 passes through the top of the water guide box 2 and three pulleys 44 installed on one side and is wound on the rotating shaft where the gear 36 and the water guide box 2 are connected. The top of the sealing plate 41 is connected to the recess 46 with a spring 2 42, and among the three pulleys 44 connected to the pull rope 43 on one side, one pulley 44 is installed on the top of the water guide box 2, and the other two pulleys 44 are installed on the surface of one side of the water guide box 2.

[0029] By designing the sealing plate mechanism 4, in the design, when the gear 36 rotates, the pull rope 43 at one end is unwound and the pull rope 43 at the other end is reeled in, and the pull rope 43 moves stably through the three pulleys 44, so when reeling in, the sealing plate 41 can be pulled up in the notch 46 to slide open the side opening of the water guide box 2, and the unwound sealing plate 41 can slide down stably to reset through the spring 2 42, and in the design, the sealing plate 41 at the inclined surface of the V-shaped plate 22 where water flows is closed, and the sealing plate 41 at the inclined surface where water does not flow is opened, so that water cannot The dirty sand flows out through the opening of the water guide box 2, and the dirty sand is docked on one side of the sealing plate 41 at the lower end of the slope of the V-shaped plate 22. When the watering direction is switched, the sealing plate 41 at this end is opened, and the sand and a small amount of water can be discharged through the slope, while the sealing plate 41 at the other end is just closed to prevent water from flowing out. In this way, there is no need to manually clean the filtered sand to avoid clogging of the filter holes, and the operation is coordinated with the watering switch. The design is ingenious and very labor-saving. It should be noted that this may cause a small amount of water to flow out, but it has little effect on the overall watering.

[0030] A pull rope 43 is divided into two sections, one section is connected to the sealing plate 41 and the other section is wound on the rotating shaft of the gear 36, and the two sections of the pull rope 43 are connected at the joint by a detachable snap ring 45. The collecting boxes 29 are snap-fitted and installed at the openings on both sides of the water guide box 2, and the bottom of the collecting box 29 is designed as a mesh plate. The bottom end of the sealing plate 41 is designed as a bevel and fits with the bevel of the V-shaped plate 22, and a sealing gasket can be bonded to the bottom surface of the sealing plate 41.

[0031] In order to further optimize the operation of the sealing mechanism 4, the bottom end of the sealing plate 41 is an inclined surface to better seal the opening, and because of the design that one end of the sealing plate 41 is always pulled up, the spring 2 42 at this end is always deformed and compressed, which is easy to be damaged. Watering is not done every day, usually every one to several days. Therefore, the pull rope 43 connected to the sealing plate 41 at the pulled up end is designed to be divided into two sections. During this period, the snap ring 45 can be unlocked so that the sealing plate can be reset, which not only protects the spring 2 42, but also prevents insects and other impurities from entering the interior. The two snap rings 45 can be reconnected for the next operation. The snap ring 45 is an existing design and will not be described in detail here. Finally, the collection box 29 collects the exported mud and sand to avoid dirtying the device.

[0032] The cleaning mechanism 5 is provided with two locations, including a curved rod 1 51 fixed on the rotating shafts on both sides of the water guide plate 23, the end of the curved rod 1 51 is rotatably connected to the curved rod 2 52, the end of the curved rod 2 52 is rotatably connected to one side of the brush plate 53, the brush plate 53 is slidably connected to the inner side of the water guide box 2, and the brush plate 53 slides along the inclined surface of the V-shaped plate 22, the curved rods 1 51 on the two cleaning mechanisms 5 are staggered on the rotating shaft of the same water guide plate 23, and the two cleaning mechanisms 5 are symmetrically designed on the two inclined surfaces of the V-shaped plate 22.

[0033] By designing the cleaning mechanism 5, when the sealing plate 41 is opened, part of the silt located at the filter hole part of the inclined surface of the V-shaped plate 22 may be blocked and unable to move down. Therefore, when switching, the curved rod 1 51 rotates with the rotating shafts on both sides of the water guide plate 23, so the curved rod 2 52 rotates and pushes the brush plate 53 to slide on both sides of the water guide box 2, pushing the residual silt on the surface of the V-shaped plate 22 to slide and fall from the opening, while the other side moves in the opposite direction, that is, moves to the upper end of the inclined surface. When the water guide plate 23 is in contact with the inclined surface of this side, the brush plate 53 is close to one end of the water guide plate 23 to avoid affecting the flow of water, and then further removes the silt in the filter hole part of the inclined surface of the V-shaped plate 22, and the cleaning mechanisms 5 on both sides can automatically circulate, which is very practical. It should be noted that the two sides of the water guide plate 23 are designed to be elevated to facilitate stable water conduction.

[0034] The present invention also provides an irrigation method of an efficient water-saving agricultural irrigation device, comprising: S1. Watering steps: During operation, the water guide plate 23 fits against an inclined surface of the V-shaped plate 22, and then the water pump 11 is started to pump water from the water tank 1. The water flows into the main cross pipe 13, the fixed pipe 31, the telescopic pipe 32 and the water inlet pipe 34 and flows to the water guide plate 23. The inclined water guide plate 23 guides the water to the inclined surface on one side of the V-shaped plate 22, and the water is filtered through the filter holes on the inclined surface and falls to the bottom, and is finally sprayed out by this row of fine-pore nozzles 15 for irrigation.

[0035] S2, switching steps: When switching is performed after a period of time, the output frequency of the water pump 11 increases and the water flow rate accelerates, so that the telescopic tube 32 overcomes the pulling force of the spring 33 and slides up, so that the toothed plate 35 drives the gear 36 to rotate, and finally the water guide plate 23 rotates and fits with the inclined surface on the other side of the V-shaped plate 22, so that water can be delivered to the L-shaped tube 14 at the other end. In this way, the irrigation position can be automatically switched.

[0036] S3, drip irrigation steps: When the water flow frequency increases, the water level in the space below the slope of the V-shaped plate 22 guiding water will rise, and the water will be introduced into the space between the two partitions 21 through the rectangular opening on the side partition 21, and the excess water can flow into the water tank 1. Then, after each irrigation is completed, the water remaining in this space can be used for drip irrigation. During drip irrigation, the solenoid valve 25 is opened, and the drip irrigation water flows into the T-shaped tube 210 and slowly drips through the drip irrigation head 24.

[0037] S4, filtering sediment cleaning steps: The sealing plate 41 at the end of the inclined surface of the V-shaped plate 22 where water is flowing is closed, and the sealing plate 41 at the end of the inclined surface where water is not flowing is opened, so that water cannot flow out through the opening of the water guide box 2 during irrigation, and dirty mud and sand are docked on one side of the sealing plate 41 at the lower end of the inclined surface of the V-shaped plate 22. When the irrigation direction is switched, the sealing plate 41 at this end is opened, and mud and a small amount of water can be discharged through the inclined surface, while the sealing plate 41 at the other end is just closed to prevent water from flowing out.

10. An irrigation method for an efficient water-saving agricultural irrigation device according to any one of claims 1 to 9, characterized in that: The irrigation method comprises the following steps: S1. Watering steps: When working, the water guide plate (23) is fitted with an inclined surface of the V-shaped plate (22), and then the water pump (11) is started to pump water from the water tank (1). The water flows into the main body transverse pipe (13), the fixed pipe (31), the telescopic pipe (32) and the water inlet pipe (34) and flows to the water guide plate (23). The inclined water guide plate (23) guides the water to the inclined surface on one side of the V-shaped plate (22), and the water is filtered through the filter holes on the inclined surface and flows to the bottom, and finally sprayed out by the row of fine-pore nozzles (15) for irrigation. S2, switching steps: When switching is performed after a period of time, the output frequency of the water pump (11) increases, the water flow rate accelerates, and the telescopic tube (32) overcomes the pulling force of the spring (33) and slides upward, so that the toothed plate (35) drives the gear (36) to rotate, and finally the water guide plate (23) rotates and fits with the inclined surface on the other side of the V-shaped plate (22), so that water can be delivered to the L-shaped tube (14) at the other end. In this way, the irrigation position can be automatically switched. S3, drip irrigation steps: When the water flow frequency increases, the water level in the space below the water-guiding slope of the V-shaped plate (22) will rise, and water will be introduced into the space between the two partitions (21) through the rectangular opening on the side partition (21), and the excess water will flow into the water tank (1). Then, after each irrigation is completed, the water remaining in this space can be used for drip irrigation. During drip irrigation, the solenoid valve (25) is opened, and the drip irrigation water flows into the T-shaped pipe (210) and slowly drips through the drip irrigation head (24). S4, filtering sediment cleaning steps: The sealing plate (41) at the end of the inclined surface of the V-shaped plate (22) where water flows is closed, and the sealing plate (41) at the end of the inclined surface where water does not flow is opened, so that water cannot flow out through the opening of the water guide box (2) during irrigation, and dirty sand and mud are docked on one side of the sealing plate (41) at the lower end of the inclined surface of the V-shaped plate (22). When the irrigation direction is switched, the sealing plate (41) at this end is opened to discharge mud and sand and a small amount of water through the inclined surface, while the sealing plate (41) at the other end is just closed to prevent water from flowing out. In this way, the sewage is automatically discharged reciprocatingly, and the brush plate (53) at the end of the open sealing plate (41) moves to the lower end of the inclined surface to push the sand, and the other end moves up to reset, completing the sewage discharge work.
