Description

Technical Field

[0001] The invention relates to the technical field of wheat drip irrigation devices, in particular to a water-saving drip irrigation device suitable for wheat irrigation and a drip irrigation control method. Background Art

[0002] During the wheat planting process, drip irrigation devices are needed to provide water to the wheat fields. Drip irrigation can deliver water directly to the roots of wheat, reducing evaporation and deep seepage. At the same time, drip irrigation can ensure that wheat obtains sufficient water during the critical growth period, promote photosynthesis, regulate temperature, and improve soil fertility, thereby promoting the growth and development of wheat.

[0003] The wheat drip irrigation device is generally composed of a water supply device, a main water pipe and a drip irrigation branch pipe. Clean water first flows through the water supply device to the water injection pipe, and then drips into the wheat field through the branch pipe. The current wheat drip irrigation device generally uses groundwater extraction to provide water for drip irrigation, but the method of extracting groundwater to provide water is relatively single, which not only reduces the reserve of groundwater, but also is not convenient for improving the utilization of water resources.

[0004] On the other hand, a patent with the search announcement number CN105660315B discloses a water-saving drip irrigation device for saline-alkali land forage planting. The device adopts underground automatic control drip irrigation technology and a series of pipeline protection measures, which not only saves water but also protects the drip irrigation equipment. However, it is difficult for the above device to maintain a good filtering effect on the water source. In order to prevent particles and impurities in the water source from clogging the drip irrigation branch pipe, a filter is generally added to the drip irrigation device to filter particles and impurities in the water source. However, after long-term use, a large amount of impurities will accumulate on the filter, which is not conducive to the passage of water and thus affects the drip irrigation effect. Therefore, personnel are required to clean the filter at regular intervals, which is very cumbersome, and when cleaning the filter, the water source needs to be turned off to stop the drip irrigation operation, which makes it difficult to continue the drip irrigation operation and affects the drip irrigation efficiency. ‌To this end, we provide a water-saving drip irrigation device and a drip irrigation control method suitable for wheat irrigation to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and to provide a water-saving drip irrigation device suitable for wheat irrigation, comprising a base, a water collecting cylinder is fixed on the outer surface of the base, a horizontal cylinder is fixedly connected above the water collecting cylinder, two symmetrical cleaning boxes are arranged above the horizontal cylinder, both of the cleaning boxes are fixedly connected to the horizontal cylinder, two sewage pipes are fixedly connected below the horizontal cylinder, a storage cylinder is arranged above the middle of the horizontal cylinder, the storage cylinder is fixedly connected to the outer surface of the horizontal cylinder and fixed to the base, and a water inlet pipe is fixedly connected to the outer surface of the bottom of the storage cylinder.

[0008] A collecting mechanism is arranged inside the storage cylinder. The collecting mechanism comprises eight expansion rods arranged in a circular array, and a waterproof cloth is fixed between every two adjacent expansion rods.

[0009] A rotating rod is fixed to the side of the two filter cylinders that are away from each other, and a fixed tube is fixed to both ends of the horizontal cylinder. The two fixed tubes are slidably connected to the two rotating rods respectively. A group of slide grooves is opened on the outer surface of each rotating rod. The number of each group of slide grooves is two and they are axially symmetrical. The slide groove group includes an inclined slide groove and a straight slide groove, and the inclined slide groove is connected to the straight slide groove. A group of sliding columns is fixed to the inner wall of the two fixed tubes. The number of each group of sliding columns is two and they are symmetrical. The two groups of slide grooves are slidably connected to the two groups of sliding columns respectively. Through the setting of the transition plug, when the filter cylinder moves in the horizontal cylinder, the filter cylinder will first drive the transition plug to block the bottom of the storage cylinder to prevent a large amount of water in the storage cylinder from leaking to the outside from the sewage pipe.

[0010] The rotation mechanism also includes a movable rod, both ends of which are fixed with toggle plates, the two toggle plates are rotatably connected to the two rotating rods respectively, a motor 1 is fixed to the outer surface of the base, a threaded rod 1 is fixed to the output end of the motor 1, the threaded rod 1 is rotatably connected to the base, a threaded block is fixed below the movable rod, the threaded block is threadedly connected to the threaded rod 1, a limiting rod 1 is fixed to the outer surface of the base, and the threaded block is slidably connected to the outer surface of the limiting rod 1.

[0011] When too many impurities accumulate in the filter cylinder directly below the storage cylinder, the control motor drives the limit rod to rotate, so that the threaded block drives the movable rod to move, and the movable rod drives the two rotating rods to move horizontally through the two toggle plates, so that the filter cylinder on the other side moves to the bottom of the storage cylinder to continue filtering the water flow, and the filter cylinder with impurities is turned 180 degrees and transferred to the bottom of the cleaning box on one side to clean the filter cylinder. By rotating the filtering and cleaning of the two filter cylinders, the device can not only maintain a good filtering effect on the water source, but also does not affect the drip irrigation operation during the cleaning process of the filter cylinder.

When cleaning the filter cartridge, the second motor is controlled to drive the second threaded rod to rotate, so that the first threaded rod moves back and forth on the second threaded rod, and when the first threaded rod moves, the first slide rod moves by toggling the swing rod, so that the arc slide rails at both ends of the bearing rod slide on the two arc slide bars respectively, so that the bearing rod moves back and forth around the filter cartridge.

[0013] The cleaning mechanism also includes two swing blocks hinged on the inner wall of the supporting rod, a limiting rod three is fixed on the outer surface of the swing rod, a sliding tube two is slidably connected to the outer surface of the limiting rod three, two sliding rods two are fixed below the sliding tube two, slots are provided on the outer surfaces of the two swing blocks, the two sliding rods two are respectively slidably connected to the inner walls of the two slots, nozzles are installed below the two swing blocks, hoses are installed on the outer surfaces of the two nozzles, and the hoses are connected to the spring air pipe.

[0014] A hinge rod is hinged on the top of the sliding tube 2, and a hinge seat is hinged on the end of the hinge rod away from the sliding tube 2. The hinge seat is fixed on the outer surface of the impact column. A bracket is sleeved on the outside of the pressure block, and the bracket is fixed on the upper surface of the arc slide rail. A telescopic spring 1 is fixed between the bracket and the impact column.

[0015] When the arc slide rail slides on the arc slide bar, the pressure block is squeezed by the protrusion and then reset by the telescopic spring 1, so that the impact column moves back and forth to impact the filter cartridge, causing the impurities in the filter cartridge to fall due to vibration. While the impact column moves back and forth, the impact column drives the slide pipe 2 to move back and forth on the limit rod 3 through the hinge seat and the hinge rod. The slide pipe 2 drives the two swing blocks to swing back and forth through the two slide rods 2, so that the strong wind sprayed by the nozzle further cleans the filter cartridge from multiple angles to prevent the filter holes of the filter cartridge from being blocked.

[0016] The collecting mechanism also includes a disc, and eight supporting rods and eight top columns are fixed to the bottom surface of the disc, the eight supporting rods are all fixedly connected to the inner wall of the storage tube, and the eight unfolding rods are respectively sleeved on the outside of the eight supporting rods, a motor three is fixed to the upper surface of the disc, a water-proof canopy is arranged above the motor three, the water-proof canopy is fixed to the disc, a threaded rod three is fixed to the output end of the motor three, a support seat is fixed to the inner wall of the storage tube, and the threaded rod three is rotatably connected to the outer surface of the support seat.

[0017] The outer surface of the threaded rod three is threadedly connected with a threaded tube two, the outer surface of the threaded tube two is fixed with a movable plate one, the bottom ends of the eight deployment rods are hinged to the movable plate one, the outer surface of the movable plate one is fixed with eight circular array sliding tubes four, the inner wall of the storage tube is fixed with eight limit rods four, and the eight limit rods four are slidably connected with the eight sliding tubes four respectively.

[0018] On rainy days, control motor three drives threaded rod three to rotate, and threaded rod three rotates to drive moving plate one to move closer to the disc through threaded tube two. Moving plate two is pressed by eight top columns, so that moving plate two approaches moving plate one. At this time, moving plate two respectively drives eight unfolding rods to move away from each other through eight diagonal support rods. After the eight unfolding rods are opened, rainwater will be drained into the storage cylinder through the waterproof cloth to collect rainwater.

[0019] A movable plate 2 is arranged above the movable plate 1, and eight limit rods 5 are fixed to the bottom surface of the movable plate 2, and the eight limit rods 5 are all slidably connected to the movable plate 1, and a telescopic spring 2 is fixed between the movable plate 1 and the movable plate 2, and the outer surfaces of the eight unfolding rods are hinged with diagonal support rods, and the eight diagonal support rods are hinged to the movable plate 2, and a capping plate is fixed to the top of each unfolding rod, and eight roller pulley groups are fixed to the inner wall of the storage cylinder, and the eight roller pulley groups respectively correspond to the positions of the eight unfolding rods.

[0020] When it is not raining, the moving plate one is controlled to move downward. After the moving plate two is not squeezed by the top column, the moving plate two is reset by the spring pressure of the telescopic spring two, so that the moving plate one is separated from the moving plate two. The moving plate two drives the unfolding rod to flip through the diagonal support rod, so that the eight unfolding rods are close to each other, and after the moving plate one moves to the bottom, the eight capping plates will cooperate with the disc to seal the opening above the storage cylinder to prevent dust and debris from entering the storage cylinder.

[0021] The water-saving drip irrigation device includes the following control method:

[0022] Step 1: On rainy days, control the moving plate 1 to move closer to the disc, so that the moving plate 2 is pressed by the eight top columns, so that the moving plate 2 is close to the moving plate 1, so that the moving plate 2 respectively moves the eight expansion rods away from each other through the eight diagonal support rods. After the eight expansion rods are opened, rainwater will be drained into the storage cylinder through the waterproof cloth. By collecting rainwater, the utilization of water resources by the device is improved.

[0023] Step 2: Rainwater or water drawn from the water inlet pipe will flow through the horizontal cylinder to the water collecting cylinder. The water in the water collecting cylinder will be drip-irrigated to the wheat field through the external main water pipe and drip irrigation branch pipe in turn. When the water flows through the horizontal cylinder, the water will be filtered by the filter cylinder directly below the receiving cylinder to prevent impurities in the water flow from clogging the drip irrigation branch pipe.

[0024] Step 3. When too many impurities accumulate in the filter cartridge directly below the storage cartridge, control the movable rod to drive the two rotating rods to move horizontally, so that the filter cartridge on the other side moves to directly below the storage cartridge to continue filtering the water flow, and the filter cartridge with impurities is turned 180 degrees and transferred to the bottom of the cleaning box on one side. The impurities in the filter cartridge will be dumped and discharged to the outside through the drain pipe, and then the filter cartridge will be knocked and vibrated by the impact column to make the impurities remaining in the filter cartridge fall due to the vibration, and the strong wind sprayed from the nozzle will further clean the filter cartridge.

[0025] Compared with the prior art, the water-saving drip irrigation device suitable for wheat irrigation has the following beneficial effects:

[0026] 1. The present invention is provided with a rotation mechanism, a swing mechanism and a cleaning mechanism. When water flows through the horizontal cylinder and is injected into the water collecting cylinder, the water will be filtered by the filter cylinder just below the storage cylinder. When too many impurities are accumulated in the filter cylinder just below the storage cylinder, the movable rod is controlled to drive the two rotating rods to move horizontally, so that the filter cylinder on the other side is moved to just below the storage cylinder to continue filtering the water flow, and the filter cylinder with impurities is turned 180 degrees and transferred to the bottom of the cleaning box on one side. The impurities in the filter cylinder will be dumped and discharged to the outside through the sewage pipe, and then the filter cylinder is knocked and vibrated by the impact column, so that the impurities retained in the filter cylinder are vibrated and dropped, and the strong wind sprayed from the nozzle further cleans the filter cylinder. By the way of rotating filtering and cleaning of the two filter cylinders, the device can not only maintain a good filtering effect on the water source, but also does not affect the drip irrigation operation during the cleaning of the filter cylinder, which is convenient and fast.

After the eight expansion rods are opened, rainwater will be drained into the storage cylinder through the waterproof cloth and collected in the water collection cylinder to provide water source for drip irrigation. By collecting rainwater, the utilization of water resources by the device is improved and water resources are saved.

[0053] A rotating rod 608 is fixed to the side of the two filter cylinders 607 away from each other, and a fixed tube 612 is fixed to both ends of the horizontal cylinder 3. The two fixed tubes 612 are respectively slidably connected to the two rotating rods 608.

The slide grooves include an inclined slide groove 611 and a straight slide groove 610, and the inclined slide groove 611 is connected to the straight slide groove 610. A set of sliding columns 613 is fixed to the inner wall of the two fixed tubes 612, each of which is two and symmetrical. The two slide grooves are respectively slidably connected to the two sets of sliding columns 613. Through the setting of the transition plug 606, when the filter cylinder 607 moves in the horizontal cylinder 3, the filter cylinder 607 will first drive the transition plug 606 to block the bottom of the storage cylinder 4 to prevent a large amount of water in the storage cylinder 4 from leaking to the outside from the sewage pipe 10.

[0054] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 When the filter cartridge 607 directly below the storage cylinder 4 moves to the bottom of the cleaning box 5 on one side, the straight slide groove 610 on the rotating rod 608 first slides on the slide column 613, so that the filter cartridge 607 moves horizontally close to the cleaning box 5. After the filter cartridge 607 is completely away from the connecting port between the storage cylinder 4 and the horizontal cylinder 3, the inclined slide groove 611 on the rotating rod 608 will slide on the slide column 613, and the filter cartridge 607 rotates.

A limiting rod 605 is fixed to the outer surface of the base 1, and the threaded block 602 is slidably connected to the outer surface of the limiting rod 605. When too many impurities accumulate in the filter cartridge 607 directly below the storage cartridge 4, the control motor 603 drives the limit rod 605 to rotate, so that the threaded block 602 drives the movable rod 601 to move, and the movable rod 601 drives the two rotating rods 608 to move horizontally through the two toggle plates 609, so that the filter cartridge 607 on the other side moves to the bottom of the storage cartridge 4 to continue filtering the water flow, and the filter cartridge 607 with impurities is turned over 180 degrees and transferred to the bottom of the cleaning box 5 on one side to clean the filter cartridge 607. By rotating the filtering and cleaning of the two filter cartridges 607, the device can not only maintain a good filtering effect on the water source, but also does not affect the drip irrigation operation during the cleaning process of the filter cartridge 607.

[0061] See also Fig. 9 and Fig.10When the arc slide rail 810 slides on the arc slide bar 815, the pressure block 814 is squeezed by the protrusion 816 and then reset by the telescopic spring 1 813, so that the impact column 812 moves back and forth to impact the filter cartridge 607, causing the impurities in the filter cartridge 607 to fall due to vibration. When the impact column 812 moves back and forth, the impact column 812 drives the slide pipe 2 802 to move back and forth on the limit rod 3 801 through the hinge seat 817 and the hinge rod 803, and the slide pipe 2 802 drives the two swing blocks 805 to swing back and forth through the two slide rods 2 804, so that the strong wind sprayed by the nozzle 806 further cleans the filter cartridge 607 from multiple angles to prevent the filter holes of the filter cartridge 607 from being blocked.

[0062] Please refer to Fig.12 , Fig.13 and Fig.14 A collecting mechanism 9 is arranged inside the storage cylinder 4, and the collecting mechanism 9 includes eight unfolding rods 915 in a circular array, and a waterproof cloth 918 is fixed between every two adjacent unfolding rods 915. The collecting mechanism 9 also includes a disc 901, and eight supporting rods 902 and eight top columns 905 are fixed to the bottom surface of the disc 901. The eight supporting rods 902 are all fixedly connected to the inner wall of the storage cylinder 4, and the eight unfolding rods 915 are respectively sleeved on the outside of the eight supporting rods 902. A motor three 903 is fixed to the upper surface of the disc 901, and a water-proof canopy 904 is arranged above the motor three 903, and the water-proof canopy 904 is fixed to the disc 901. A threaded rod three 906 is fixed to the output end of the motor three 903, and a support seat 907 is fixed to the inner wall of the storage cylinder 4, and the threaded rod three 906 is rotatably connected to the outer surface of the support seat 907.

[0063] The outer surface of the threaded rod three 906 is threadedly connected to the threaded tube two 909, and the outer surface of the threaded tube two 909 is fixed with a movable plate one 908. The bottom ends of the eight unfolding rods 915 are hinged to the movable plate one 908, and the outer surface of the movable plate one 908 is fixed with eight circular array sliding tubes four 910. The inner wall of the storage tube 4 is fixed with eight limit rods four 911, and the eight limit rods four 911 are slidably connected with the eight sliding tubes four 910 respectively.

[0064] Please refer to Fig.12 , Fig.13 and Fig.14 On rainy days, the control motor three 903 drives the threaded rod three 906 to rotate. The threaded rod three 906 rotates through the threaded tube two 909 to drive the movable plate one 908 to move close to the disc 901. The movable plate two 912 is pressed by the eight top columns 905, so that the movable plate two 912 is close to the movable plate one 908. At this time, the movable plate two 912 uses the eight diagonal support rods 916 to respectively keep the eight expansion rods 915 away from each other. After the eight expansion rods 915 are opened, rainwater will be drained into the storage tube 4 through the waterproof cloth 918, and the rainwater will be collected.

[0065] A movable plate 2 912 is arranged above the movable plate 1 908, and eight limit rods 5 914 are fixed to the bottom surface of the movable plate 2 912, and the eight limit rods 5 914 are all slidably connected to the movable plate 1 908, and a telescopic spring 2 913 is fixed between the movable plate 1 908 and the movable plate 2 912, and the outer surfaces of the eight unfolding rods 915 are hinged with diagonal support rods 916, and the eight diagonal support rods 916 are hinged to the movable plate 2 912, and a capping plate 917 is fixed to the top of each unfolding rod 915, and eight roller pulley groups 919 are fixed to the inner wall of the storage tube 4, and the eight roller pulley groups 919 correspond to the positions of the eight unfolding rods 915 respectively. When the moving plate 1 908 moves close to the disk 901, the control motor 3 903 drives the threaded rod 3 906 to rotate slowly, and the threaded rod 3 906 cooperates with the threaded tube 2 909 to make the moving plate 1 908 slowly move upward close to the disk 901, and the telescopic spring 2 913 has a high compression and torsion resistance, so that when the moving plate 1 908 moves upward, the moving plate 2 912 can follow the movement, and the moving plate 1 908 and the moving plate 2 912 will not move close to each other during the upward movement. When the moving plate 1 908 continues to move upward and the moving plate 2 912 contacts the eight top pillars 905, the moving plate 2 912 is pressed by the eight top pillars 905, and the telescopic spring 2 913 is compressed, and the moving plate 2 912 approaches the moving plate 1 908. At this time, the moving plate 2 912 respectively keeps the eight expansion rods 915 away from each other through the eight diagonal bracing rods 916.

[0066] By setting the water-proof awning 904, when collecting rainwater, the rainwater above the water-proof awning 904 will flow into the storage tube 4 along the conical surface of the water-proof awning 904. In the rainy day use environment, a shielding net is set above the storage tube 4, and the position of the shielding net is higher than the eight opened waterproof cloths 918 to prevent external impurities and plant roots from entering the storage tube 4 with rainwater.

[0067] Please refer to Fig.12 , Fig.13 and Fig.14 When it is not raining, the moving plate 1 908 is controlled to move downward. After the moving plate 2 912 is not squeezed by the top column 905, the moving plate 2 912 is reset by the spring pressure of the telescopic spring 2 913, so that the moving plate 1 908 and the moving plate 2 912 are separated. The moving plate 2 912 drives the unfolding rod 915 to flip through the diagonal support rod 916, so that the eight unfolding rods 915 are close to each other, and after the moving plate 1 908 moves to the bottom, the eight capping plates 917 will cooperate with the disc 901 to block the opening above the storage tube 4 to prevent dust and debris from entering the storage tube 4.

[0068] The water-saving drip irrigation device includes the following control method:

[0069] Step 1. On rainy days, control motor 3 903 to drive threaded rod 3 906 to rotate. Threaded rod 3 906 rotates through threaded tube 2 909 to drive movable plate 1 908 to move close to disc 901. Movable plate 2 912 is pressed by eight top columns 905, so that movable plate 2 912 is close to movable plate 1 908. At this time, movable plate 2 912 uses eight diagonal support rods 916 to respectively move eight unfolding rods 915 away from each other. After the eight unfolding rods 915 are opened, rainwater will be drained into the storage tube 4 through the waterproof cloth 918. By collecting rainwater, the device can improve the utilization of water resources.

[0070] Step 2: Drip irrigation is carried out after filtering the water source. Rainwater or water drawn from the water inlet pipe 11 will flow into the water collecting cylinder 2 through the horizontal cylinder 3. The water in the water collecting cylinder 2 will drip irrigate the wheat field in turn through the main water pipe and drip irrigation branch pipe arranged externally. When the water flows through the horizontal cylinder 3, the water will be filtered by the filter cylinder 607 just below the receiving cylinder 4 to prevent impurities in the water flow from clogging the drip irrigation branch pipe.

[0071] Step 3: When too many impurities are accumulated in the filter cartridge 607 directly below the storage cartridge 4, the control motor 1 603 drives the limit rod 1 605 to rotate, so that the threaded block 602 drives the movable rod 601 to move, and the movable rod 601 drives the two rotating rods 608 to move horizontally through the two toggle plates 609, so that the filter cartridge 607 on the other side moves to the directly below the storage cartridge 4 to continue filtering the water flow;

[0072] When the filter cartridge 607 containing impurities moves, the straight slide groove 610 on the rotating rod 608 slides on the slide column 613 first, so that the filter cartridge 607 moves horizontally close to the cleaning box 5. After the filter cartridge 607 is completely away from the connecting port between the storage cylinder 4 and the horizontal cylinder 3, the inclined slide groove 611 on the rotating rod 608 slides on the slide column 613, and the filter cartridge 607 rotates. When the filter cartridge 607 moves to the bottom of the cleaning box 5, the filter cartridge 607 turns 180 degrees, and the opening of the filter cartridge 607 faces downward, and the impurities in the filter cartridge 607 will be dumped into the sewage pipe 10 and discharged to the outside.

[0073] Then, the motor 2 707 is controlled to drive the threaded rod 2 708 to rotate, so that the threaded tube 1 705 moves back and forth on the threaded rod 2 708. When the threaded tube 1 705 moves, it will move the swing rod 701 through the slide rod 1 704. When the swing rod 701 moves, it will drive the arc slide rail 810 to slide on the arc slide bar 815. At this time, the pressure block 814 is squeezed by the protrusion 816 and then reset by the telescopic spring 1 813, so that the impact column 812 moves back and forth to hit the filter cartridge 607, so that the impurities retained in the filter cartridge 607 are vibrated and fall off;

[0074] While the impact column 812 moves back and forth, the impact column 812 will drive the sliding pipe 802 to move back and forth on the limiting rod 3 801 through the hinge seat 817 and the hinge rod 803. The sliding pipe 802 drives the two swing blocks 805 to swing back and forth through the two sliding rods 804, so that the strong wind sprayed by the nozzle 806 can further clean the filter cartridge 607 at multiple angles to prevent the filter holes of the filter cartridge 607 from being blocked. The device uses the method of rotating filtering and cleaning of the two filter cartridges 607 to not only maintain a good filtering effect on the water source, but also does not affect the drip irrigation operation during the cleaning process of the filter cartridge 607, which is convenient and quick.
