Description

Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to staggered water-saving intermittent irrigation equipment for fields. Background Art

[0002] In agricultural production, it is often necessary to irrigate the crops planted in the fields. When irrigating some small plots, the sprinkler tank is set up on the side of the field, and the crops on the field are irrigated through evenly distributed nozzles installed on the outside of the water pipe. Although this type of irrigation can achieve the purpose of saving water, because the sprayed water is parabolic, the descending section of the parabola sprays more water, while the field below the rising section of the water flow on the side close to the water pipe has less water irrigation, which is prone to uneven irrigation. Therefore, in order to solve the above problem, a staggered water-saving intermittent irrigation equipment for fields is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a staggered water-saving intermittent irrigation device for fields to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] As an optional solution of the staggered water-saving intermittent irrigation equipment for fields described in the present invention, the staggered water-saving intermittent irrigation equipment for fields comprises a bracket and an irrigation device, the irrigation device is mounted on the top of the bracket, the input end of the irrigation device is connected to an external pipe, the other end of the external pipe is connected to an external water source, the output end of the irrigation device is connected to an irrigation pipe, the outside of the irrigation pipe is connected to evenly distributed nozzle direction adjustment modules for adjusting the spraying area, and the outside of the irrigation pipe is also connected to a water pressure adjustment module for adjusting the water pressure, both sides of the water pressure adjustment module are fixedly connected to reinforcement frames, the top of the reinforcement frame is fixedly connected to the irrigation pipe, the other end of the irrigation pipe is connected to an impurity removal module for collecting impurities in the water, and the impurity removal module is fixed to the top of the bracket on one side, the water sprayed by the traditional irrigation equipment is in a parabolic shape, and the descending section of the parabola sprays There is a large amount of water, while the amount of water irrigated to the field below the rising section of the water flow on the side close to the water pipe is small, which is prone to uneven irrigation. When the device is in use, a water pressure regulating module is added to the outside of the irrigation pipe. At this time, the water pressure inside the irrigation pipe can be adjusted, thereby changing the irrigation curve of the water. Through the continuous start of the water pressure regulating module, this intermittent sprinkler irrigation method can circulate and effectively irrigate the field below the original rising section, and then cooperate with the use of the nozzle direction adjustment module to ensure uniform irrigation of the field. During long-term use, impurities will inevitably accumulate inside the irrigation pipe. If they are not handled for a long time, the irrigation efficiency will be affected. The impurity removal module set up can effectively deal with the impurities inside the irrigation pipe, and the water flow inside the impurity removal module circulates to ensure that the water is fully utilized.

[0006] As an optional solution for the staggered water-saving intermittent irrigation equipment for fields described in the present invention, a first one-way valve is also installed on the outside of the irrigation pipe between the water pressure regulating module and the irrigation equipment. During irrigation, the first one-way valve ensures that water can only flow in one direction, so that the purpose of intermittent irrigation can be achieved by adjusting the water pressure.

[0007] As an optional solution of the staggered water-saving intermittent irrigation equipment for fields described in the present invention, the water pressure regulating module includes a water tank, a connecting pipe and a motor, the two sides of the water tank are fixedly connected to the reinforcement frame, the top of the water tank is connected to a connecting pipe, the top of the connecting pipe is connected to the irrigation pipe, the inside of the water tank is fixedly connected to a motor, the end of the main shaft of the motor is fixedly connected to a reciprocating screw, the outer side of the reciprocating screw is slidably connected to a slider, and the outer side of the slider is fixedly connected to a moving sleeve, the top of the moving sleeve is fixedly connected to a push plate, and the top of the push plate is fixedly connected to a first sealing plate. When the water pressure inside the irrigation pipe is adjusted, the motor is started, and the motor The reciprocating screw is driven to rotate, forcing the slider to slide, and the slider drives the movable sleeve to move, and the movable sleeve drives the push plate to move. At this time, when the push plate moves downward, it can extract part of the water inside the irrigation pipe. At this time, the water pressure inside the irrigation pipe is weakened, and the pressure of the water sprayed is small, and the irrigation area is reduced. When the push plate moves upward, the water pressure inside the irrigation pipe increases, and the pressure of the water sprayed increases, and the irrigation area is increased. Such a cycle ensures that the fields below the original rising and descending sections of the water flow are irrigated, thereby achieving the purpose of uniform irrigation to a certain extent. The setting of the first sealing plate ensures that the water flow cannot flow under the push plate, ensuring that the equipment can be used normally.

[0008] As an optional solution of the staggered water-saving intermittent irrigation equipment for fields described in the present invention, guide rods are provided on both sides of the movable sleeve, and the top of the guide rod is fixedly connected to the push plate, the bottom of the guide rod is slidably connected to the guide sleeve, the outer side of the guide sleeve is fixedly connected to the water tank, and the provided guide rods and guide sleeves can ensure that the push plate can move up and down stably, avoiding the push plate itself from rotating under the action of the movable sleeve.

[0009] As an optional solution of the staggered water-saving intermittent irrigation equipment for fields described in the present invention, the nozzle direction adjustment module includes a guide cylinder, a moving rod and a moving plate, one end of the guide cylinder is connected to the irrigation pipe, the inside of the guide cylinder is slidably connected with the moving rod, one end of the moving rod is fixedly connected with the moving plate, the other end of the moving plate is fixedly connected with the second sealing plate, the outer side of the moving rod is also fixedly connected with evenly distributed hanging rings, the front and rear sides of the irrigation pipe are connected with a hose, and the other end of the hose is fixedly connected with a nozzle.

[0010] The outer side of the nozzle is rotatably connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to a fixing plate, and one end of the fixing plate is fixedly connected to the irrigation pipe;

[0011] The upper and lower sides of the sprinkler head are rotatably connected with connecting rods, and the other ends of the connecting rods are installed with hooks. Although the water pressure regulating module can achieve the purpose of uniform irrigation to a certain extent, it still has a certain irrigation blind area, and its irrigation area cannot be adjusted, which limits the use of the equipment to a certain extent. The present device is equipped with a sprinkler head direction adjustment module on the outside. When the water pressure inside the irrigation pipe increases, the water will squeeze the second sealing plate, and the second sealing plate can drive the moving plate to move. At this time, the moving rod can be moved, and the hanging ring on the outside of the moving rod is connected to the hook, so as to achieve the purpose of adjusting the sprinkler head. When spraying a large area, by passing the connecting rod above the sprinkler head through the hook, the sprinkler head can be adjusted. It is connected to the hanging ring above through a hook. When the water pressure increases, the nozzle automatically rises, and large-area irrigation can be achieved. The hook is continuously connected to the hanging rings at different positions above. At this time, the irrigation area can be adjusted in a small range. When spraying a small area, the connecting rod under the nozzle is connected to the hanging ring below through a hook. When the water pressure increases, the nozzle automatically rotates downward, and small-area irrigation can be achieved. The hook is continuously connected to the hanging rings at different positions below. At this time, the irrigation area can be adjusted in a small range. The hook adopts a self-locking type. Once connected to the hanging ring, it is not easy to fall off. The soft hose can ensure that the nozzle can rotate to a certain extent.

[0012] As an optional solution for the staggered water-saving intermittent irrigation equipment for fields described in the present invention, filter nets are provided on the outer sides of the opposite ends of the hoses on the front and rear sides, and the outer sides of the filter nets are fixedly connected to the irrigation pipe. The setting of the filter nets ensures that when the water flow moves to the inside of the nozzle, its impurities are blocked inside the irrigation pipe to avoid clogging the nozzle.

[0013] As an optional solution for the staggered water-saving intermittent irrigation equipment for fields described in the present invention, the impurity removal module includes a circulation box, a filter cartridge and a top cover, the outer side of the circulation box is fixedly connected with a docking tube, the other end of the docking tube is fixedly connected to the irrigation pipe, a manual valve is installed on the outer side of the docking tube, the bottom of the circulation box is fixedly connected to the bracket, the inner side of the circulation box is provided with a filter cartridge, the top of the filter cartridge is installed with a top cover, and the bottom of the top cover is sealed with the circulation box. During a long period of irrigation, a large amount of impurities will accumulate inside the irrigation pipe. At this time, the inside of the irrigation pipe needs to be cleaned. At this time, the manual valve is manually opened, and the water flow inside the irrigation pipe will move to the inside of the filter cartridge, and the water will be re-delivered to the inside of the irrigation pipe through the circulation pipe above. At this time, the water can be used normally, and the impurities are filtered into the filter cartridge. When the cleaning work is completed, the filter cartridge can be taken out by moving the top cover, and then the impurities can be easily processed.

[0014] As an optional solution for the staggered water-saving intermittent irrigation equipment for fields described in the present invention, a laterally arranged limit plate is fixedly connected to the inner side of the circulation box, and the outer side of the limit plate is engaged with the filter cartridge. The arranged limit plate ensures that the filter cartridge is placed inside the circulation box at a certain angle, so that the water inlet end opening of the filter cartridge is connected to the docking pipe, thereby facilitating the entry of impurities therein.

[0015] As an optional solution for the staggered water-saving intermittent irrigation equipment for fields described in the present invention, the outside of the circulation box is also connected to a circulation pipe, the other end of the circulation pipe is connected to the irrigation pipe, and a second one-way valve is installed on the outside of the circulation pipe. The circulation pipe is used to ensure that the water inside the filter cartridge can circulate and that impurities can continue to enter the filter cartridge. At the same time, the second one-way valve ensures that water can only flow in one direction, thereby ensuring the filtering effect of the device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention uses a water pressure regulating module to adjust the water pressure inside the irrigation pipe to activate the nozzle direction regulating module, so that the spraying direction of the nozzle can be automatically adjusted, so that during the water body irrigation process, the nozzle automatically adjusts its angle to achieve the purpose of uniformly spraying the crops on the field.

[0018] The water pressure of traditional irrigation equipment is generally constant, which easily leads to more water in the descending section of the sprayed water, while less water in the field below the ascending section. The device installs a water pressure regulating module on the outside of the irrigation pipe, and its continuous starting motor can drive the reciprocating screw to rotate, and then the movable sleeve moves up and down under the action of the slider, thereby driving the push plate and the first sealing plate to move up and down, and finally the water flowing normally in the irrigation pipe is pumped into the water tank. At this time, the water pressure inside the irrigation pipe is reduced, and the field below the previous ascending section can be supplemented with water for irrigation. When the push plate moves upward, it can increase the water pressure inside the irrigation pipe. Compared with the normal water pressure, its actual water pressure is greater. Under the same irrigation equipment, the device can irrigate a larger area;

[0019] At the same time, when irrigating the field, the device is more operable. When spraying a large area, the connecting rod and the hook are connected to the upper hanging ring. When the water pressure inside the irrigation pipe is high, the movable plate is automatically lifted up. At this time, the hanging ring, the hook and the connecting rod can be driven to move by the moving rod, and finally the nozzle is tilted to achieve large-area irrigation. When the lower hook is connected to the lower hanging ring, the spraying area is reduced, but the field close to the irrigation pipe can be irrigated to achieve uniform spraying of all parts of the field.

[0020] At the same time, the hook can be connected to the hanging rings at different positions according to the actual situation, and then the rotation angle of the nozzle can be controlled to achieve the control of the spraying area;

[0021] During long-term use, it is inevitable that impurities will be located inside the irrigation pipe, which may affect the irrigation quality. The device is equipped with a filter screen at the connection between the irrigation pipe and the hose, which can prevent impurities from clogging the nozzle. At the same time, an impurity removal module is provided at one end of the irrigation pipe to remove impurities.

[0022] When it is necessary to deal with the impurities inside the irrigation pipe, the manual valve is opened. At this time, the water inside the irrigation pipe enters the hose, and the water is filtered through the filter cartridge. The impurities are located inside the filter cartridge, and the water re-enters the irrigation pipe through the circulation pipe to achieve centralized treatment of impurities. A one-way valve is installed on the outside of the circulation pipe for one-way flow of water, ensuring that the water is fully utilized and that the impurities inside the irrigation pipe can be collected.

[0032] The water sprayed by the traditional irrigation equipment is in the shape of a parabola. The descending section of the parabola sprays more water, while the field below the rising section of the water flow on the side close to the water pipe has less water for irrigation, which is prone to uneven irrigation. When the present device is in use, a water pressure regulating module 6 is added to the outside of the irrigation pipe 4. At this time, the water pressure inside the irrigation pipe 4 can be adjusted, thereby changing the irrigation curve of the water. By continuously starting the water pressure regulating module 6, this intermittent sprinkler irrigation method can circulate and effectively irrigate the field below the original rising section, and then cooperate with the use of the nozzle direction adjustment module 8. At this time, it can be ensured that the field is irrigated evenly. During long-term use, impurities will inevitably accumulate inside the irrigation pipe 4. If they are not handled for a long time, the irrigation efficiency will be affected. The impurity removal module 9 provided can effectively handle the impurities inside the irrigation pipe 4, and the water flow inside the impurity removal module 9 circulates to ensure that the water is fully utilized.

[0033] Example 2

[0034] This embodiment is an improvement made to the first embodiment. Figure 1 Specifically, a first one-way valve 5 is also installed on the outside of the irrigation pipe 4 between the water pressure regulating module 6 and the irrigation equipment 2.

[0035] During irrigation, the first one-way valve 5 ensures that water can only flow in one direction, so that the purpose of intermittent irrigation can be achieved by adjusting the water pressure.

[0036] Example 3

[0037] This embodiment is an improvement made to Example 2. Figure 1 , Figure 2 and Figure 3 Specifically, the water pressure regulating module 6 includes a water tank 601, a connecting pipe 602 and a motor 603. Both sides of the water tank 601 are fixedly connected to the reinforcement frame 7. The top of the water tank 601 is connected to the connecting pipe 602, and the top of the connecting pipe 602 is connected to the irrigation pipe 4. The inside of the water tank 601 is fixedly connected to the motor 603, and the end of the main shaft of the motor 603 is fixedly connected to the reciprocating screw rod 604, and the outer side of the reciprocating screw rod 604 is slidably connected to the slider 606, and the outer side of the slider 606 is fixedly connected to the movable sleeve 605, the top of the movable sleeve 605 is fixedly connected to the push plate 607, and the top of the push plate 607 is fixedly connected to the first sealing plate 608.

[0038] When the water pressure inside the irrigation pipe 4 is adjusted, the motor 603 is started, and the motor 603 drives the reciprocating screw 604 to rotate, forcing the slider 606 to slide, and the slider 606 drives the movable sleeve 605 to move, and the movable sleeve 605 drives the push plate 607 to move. At this time, when the push plate 607 moves downward, it can extract a part of the water inside the irrigation pipe 4. At this time, the water pressure inside the irrigation pipe 4 is weakened, and the pressure of the water sprayed is small, and its irrigation area is reduced. When the push plate 607 moves upward, the water pressure inside the irrigation pipe 4 increases, and the pressure of the water sprayed increases, and its irrigation area is increased. Such a cycle ensures that the fields below the original rising section and the descending section of the water flow are irrigated, thereby achieving the purpose of uniform irrigation to a certain extent. The setting of the first sealing plate 608 ensures that the water flow cannot flow below the push plate 607, ensuring that the equipment can be used normally.

[0045] The upper and lower sides of the nozzle 807 are rotatably connected with connecting rods 811, and the other ends of the connecting rods 811 are installed with hooks 812.

[0046] Although the water pressure regulating module 6 can achieve the purpose of uniform irrigation to a certain extent, it still has certain blind spots for irrigation, and its irrigation area cannot be adjusted, which limits the use of the equipment to a certain extent. The device is equipped with a nozzle direction regulating module 8 on the outside. When the water pressure inside the irrigation pipe 4 increases, the water will squeeze the second sealing plate 804, and the second sealing plate 804 can drive the movable plate 803 to move. At this time, the movable rod 802 can be moved, and the hanging ring 805 on the outside of the movable rod 802 is connected to the hook 812, so as to achieve the purpose of adjusting the nozzle 807. When spraying over a large area, the connecting rod 811 above the nozzle 807 is connected to the hanging ring 805 above through the hook 812. When the water pressure increases, the nozzle direction regulating module 8 When the water pressure increases, the nozzle 807 automatically turns downward, and small-area irrigation can be achieved. The hook 812 is continuously connected to the hanging ring 805 at different positions above, and the irrigation area can be adjusted in a small range. When spraying a small area, the connecting rod 811 below the nozzle 807 is connected to the hanging ring 805 below through the hook 812. When the water pressure increases, the nozzle 807 automatically turns downward, and small-area irrigation can be achieved. The hook 812 is continuously connected to the hanging ring 805 at different positions below, and the irrigation area can be adjusted in a small range. The hook 812 adopts a self-locking type.
