Description

Technical Field

[0001] The present invention relates to the technical field of irrigation equipment, and in particular to agricultural water-fertilizer integrated irrigation equipment and an irrigation method. Background Art

[0002] Irrigation is a technical measure to supplement the water needed by crops. In the process of agricultural production, in order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation is necessary to make up for the lack of natural rainfall. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of medicinal plants, the growth stage, the climate and the soil conditions. It should be timely, appropriate and reasonable. Its types mainly include irrigation before sowing, irrigation for seedling promotion, irrigation during the growth period and irrigation in winter.

[0003] Integrated water and fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. In the process of agricultural production, in order to ensure the growth of crops, in addition to the necessary water, nutrients are also necessary for crop growth, so it is necessary to fertilize crops. Through the integrated water and fertilizer technology, fertilization can be carried out during crop irrigation. Integrated water and fertilizer is to use a pressure system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type. The fertilizer solution is mixed with irrigation water through a controllable pipeline system to supply water and fertilizer. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipes and drippers to evenly, regularly and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always maintains looseness and appropriate water content. At the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the needs of different growth periods are designed, and water and nutrients are directly provided to crops in a regular and quantitative manner in proportion.

[0004] During the use of existing agricultural water-fertilizer integrated irrigation equipment, it is difficult to fully dissolve solid fertilizers in water, and solid fertilizers are prone to caking, which makes the solid fertilizers insufficiently soluble in water, resulting in uneven crop fertilization, and undissolved solid fertilizers are deposited at the bottom of the water storage tank. During the irrigation process, solid fertilizers are prone to flow into the pipes with the water flow, causing blockage of the pipes and equipment. At the same time, there is no control over the intake of solid fertilizers. Summary of the invention

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 8 As shown, the agricultural water-fertilizer integrated irrigation equipment of the present invention comprises a base 1, a water storage mechanism 2 is fixed on the top of the base 1, a feeding mechanism 19 is provided on the top of the water storage mechanism 2, and a liquid discharge mechanism 8 is provided at the bottom of the water storage mechanism 2; Figure 1 shown.

[0034] The water storage mechanism 2 includes a water storage tank 3, and a feeding mechanism 19 is provided on the top of the water storage tank 3. Figure 2 , Figure 3 and Figure 6 As shown, the feeding mechanism 19 includes a feeding pipe 20 fixedly mounted on the upper surface of the water storage tank 3, a fixing frame 26 fixedly mounted on the inner surface of the feeding pipe 20, a driven worm gear 27 rotatably connected inside the fixing frame 26, crushing knives 28 fixedly mounted on both ends of the rotating shaft of the driven worm gear 27, the driven worm gear 27 and the crushing knives 28 are installed through the fixing frame 26, solid fertilizer is poured into the feeding pipe 20 for storage, and the rotation of the driven worm gear 27 can drive the crushing knives 28 to rotate to crush large or agglomerated solid fertilizers, thereby facilitating the dissolution of the solid fertilizers in water.

[0035] A mounting base 21 is also fixedly provided on the top of the water tank 3, and a motor 22 is fixedly provided on the upper surface of the mounting base 21. The motor 22 is installed by the mounting base 21, so that the stability of the motor 22 during operation can be increased. A transmission worm 23 is coaxially fixedly provided on the output shaft of the motor 22 through a coupling, and the lower end of the transmission worm 23 is coaxially fixedly provided on the upper end of the stirring shaft 5. A driven worm 24 is rotatably connected inside the mounting base 21, and a transmission worm wheel 25 is coaxially fixedly provided on one end of the driven worm 24 close to the transmission worm 23, and the transmission worm wheel 25 is meshed with the transmission worm 23. The end of the driven worm 24 away from the transmission worm wheel 25 penetrates the feed pipe 20 and extends to the inside of the fixed frame 26, and the driven worm 24 is meshed with the driven worm wheel 27, so that the operation of the motor 22 can drive the transmission worm 23 to rotate, and the transmission worm wheel 25 can drive the driven worm 24 to rotate, thereby driving the driven worm wheel 27 and the crushing knife 28 to rotate.

[0036] The upper surface of the water storage tank 3 is provided with a feed port connected to the feed pipe 20, through which the crushed solid fertilizer can enter the water storage tank 3 and mix and dissolve with water. A blocking mechanism 29 is provided at the feed port. Figure 7 and Figure 8As shown, the material blocking mechanism 29 includes a mobile frame 35 fixed on the top wall of the water storage tank 3, and a material blocking plate 34 is slidably connected inside the mobile frame 35. The material blocking plate 34 and the mobile frame 35 correspond to the positions of the feed port. Two return springs 36 are fixed on the outer surface of the material blocking plate 34. The two return springs 36 are fixed on the inner surface of the mobile frame 35 at one end away from the material blocking plate 34. The material blocking plate 34 is installed by the mobile frame 35 in cooperation with the return springs 36. The material blocking plate 34 seals the feed port to prevent solid fertilizer from entering the water storage tank 3. When the solid fertilizer enters the water storage tank 3, the return spring 36 elastic force can drive the material blocking plate 34 to move and seal the feed port. Two stoppers 37 are fixed on the inner surface of the mobile frame 35. The two stoppers 37 correspond to the positions of the material blocking plate 34. The stoppers 37 can limit the position of the material blocking plate 34 to prevent the displacement of the material blocking plate 34 from affecting the blocking and entry of solid fertilizer. The stopper 37 is a small raised block made of elastic material, which is fixed on the inner surface of the movable frame 35. The stopper 37 abuts against the baffle plate 34, and the baffle plate 34 can move inside the movable frame 35. The stopper 37 can temporarily limit the slow movement of the baffle plate 34. As the elastic tension on the baffle plate 34 gradually increases, the baffle plate 34 gradually squeezes the elastic stopper 37. When the baffle plate 34 squeezes the elastic stopper to a certain extent, the baffle plate 34 and the stopper 37 are instantly separated and move with the elastic force of the coil spring 32, so that the baffle plate 34 can be instantly opened or closed, shortening the opening and closing time of the baffle plate 34 and reducing the opening and closing time of the baffle plate 34. During the process, solid fertilizer falls, so that the amount of material entering the water tank 3 is more accurate; and the baffle 37 divides the interior of the movable frame 35 into two movable spaces. When the baffle plate 34 is located in one of the spaces, the feed pipe 20 can be closed, and when the baffle plate 34 moves to the other space, the feed pipe 20 can be opened; when the baffle plate 34 is located in the other space to open the feed pipe 20, as the water flow at the water injection pipe drives the rotating rod 38 and the fan plate 39 to rotate, the baffle plate 34 can be continuously pulled by the coil spring 32 to prevent it from resetting. When the water flow at the water injection pipe stops, the baffle plate 34 can be pulled by the reset spring 36 to instantly move and reset the sealed feed pipe 20. The two sides of the bottom of the movable frame 35 are inclined. By setting the two sides of the bottom of the movable frame 35 to be inclined, solid waste can be easily slipped off, and solid fertilizer can be prevented from accumulating inside the movable frame 35. A fixed plate 30 is fixedly provided on the top wall of the water storage tank 3, and a winding rod 31 is rotatably connected inside the fixed plate 30. A coil spring 32 is coaxially sleeved on the outer side of the winding rod 31. The inner end of the coil spring 32 is fixedly arranged on the circumferential surface of the winding rod 31, and a connecting plate 33 is fixedly connected to the outer end of the coil spring 32. The end of the connecting plate 33 away from the coil spring 32 is rotatably connected to the end of the baffle plate 34 away from the return spring 36. The winding rod 31 is installed through the fixed plate 30, so that the winding rod 31 is rotated to wind up the coil spring 32. As the coil spring 32 is wound, the connecting plate 33 can pull the baffle plate 34 to move, thereby opening the feed port, allowing solid fertilizer to enter the water storage tank 3.

[0037] The winding rod 31 is coaxially fixed with a rotating rod 38 at one end away from the coil spring 32. The circumferential surface of the rotating rod 38 is connected to a plurality of fan plates 39 through a torsion spring. When water is injected into the water storage tank 3 through the water injection pipe, the fan plate 39 can drive the rotating rod 38 to rotate, thereby driving the winding rod 31 to rotate and rewind the coil spring 32. When the coil spring 32 is wound, the rotating rod 38 stops rotating. As the water injection continues, the fan plate 39 is driven to rotate around the torsion spring, which can prevent the rotating rod 38 from continuing to rotate. The circumferential surface of the rotating rod 38 is fixed with a plurality of stoppers. Plate 40 and fan plate 39 correspond to the positions of baffle plate 40 respectively. When the water flow at the water injection pipe stops, the fan plate 39 can be driven to rotate by the elastic force of the torsion spring. As the fan plate 39 rotates, the contact with the baffle plate 40 is released. The position of the fan plate 39 is restricted by the baffle plate 40 to avoid the fan plate 39 rotating too much and affecting the subsequent use. A water injection pipe is fixed on the upper surface of the water tank 3, and the water injection pipe corresponds to the position of the fan plate 39. Water is poured into the water tank 3 through the water injection pipe. As the water flows down, it impacts the fan plate 39, thereby driving the rotating rod 38 to rotate.

[0038] A mixing chamber and a stirring chamber are arranged from top to bottom inside the water storage tank 3, and the mixing chamber and the stirring chamber are separated by a partition 4, and a stirring shaft 5 is provided between the mixing chamber and the stirring chamber, and a plurality of mixing rods 7 are arranged in a circular array on the stirring shaft 5 of the mixing chamber, and a plurality of stirring rods 6 are arranged in a circular array on the stirring shaft 5 of the stirring chamber. Solid fertilizer and water enter the mixing chamber, and the solid fertilizer and water can be stirred and mixed by the rotation of the mixing rod 7. The mixed solution enters the stirring chamber, and the solid matter in the water-fertilizer solution is prevented from precipitating by the rotation of the stirring rod 6. A discharge port is provided inside the partition 4, and a discharge valve is fixed inside the discharge port. When the solid fertilizer and water are mixed, the discharge valve is opened, and the water-fertilizer solution can flow into the stirring chamber through the discharge port for subsequent use.

[0039] The side wall of the mixing chamber is connected to a liquid outlet mechanism 8, which includes a liquid pump 9 fixedly mounted on one side of the upper surface of the base 1. The liquid pump 9 is connected to the water storage tank 3 through a connecting pipe. A liquid outlet pipe 10 is fixedly mounted at the water outlet end of the liquid pump 9. The liquid outlet pipe 10 is arranged in a T shape. Two nozzles 11 are fixedly mounted at both ends of the liquid outlet pipe 10 away from the liquid pump 9. When the liquid pump 9 is working, the water fertilizer solution in the water storage tank 3 is extracted through the connecting pipe, and the water fertilizer solution is poured into the nozzle 11 through the liquid outlet pipe 10 and sprayed out for irrigation. Figure 5As shown, two mounting frames 12 are fixedly arranged on the lower surface of the base 1, and two sprinklers 11 are rotatably connected inside the two mounting frames 12 respectively. The sprinklers 11 are installed through the mounting frames 12, and the sprinklers 11 can be rotated to expand the irrigation area. Four mounting plates 13 are fixedly arranged at the four corners of the lower surface of the base 1, and a rotating shaft 14 is rotatably connected between every two mounting plates 13. Rollers 15 are coaxially fixedly arranged at both ends of the rotating shaft 14. The rotating shaft 14 and the rollers 15 are installed through the mounting plates 13, so that the rotating shaft 14 and the rollers 15 can drive the base 1 to move when they rotate. Two special-shaped bevel gears 16 are fixedly arranged at both ends of the front rotating shaft 14, and transmission bevel gears 17 are fixedly arranged at one end of the rotating rods of the two sprinklers 11 close to the special-shaped bevel gears 16. The two transmission bevel gears 17 are respectively connected to the special-shaped bevel gears 16. The two special-shaped bevel gears 16 are meshed with each other. When the rotating shaft 14 rotates, the special-shaped bevel gears 16 can be driven to rotate, and the transmission bevel gears 17 can be used to drive the nozzle 11 to rotate. When the special-shaped bevel gears 16 are separated from the transmission bevel gears 17, the nozzle 11 rotates under the action of gravity, so that the nozzle 11 rotates back and forth. The outer surfaces of the two mounting plates 13 are fixed with protective shells 18. The special-shaped bevel gears 16 and the transmission bevel gears 17 are both located inside the protective shells 18. The protective shells 18 protect the special-shaped bevel gears 16 and the transmission bevel gears 17, and can block external dust, so as to prevent dust from adhering to the outer surfaces of the special-shaped bevel gears 16 and the transmission bevel gears 17, and affecting the normal rotation of the special-shaped bevel gears 16 and the transmission bevel gears 17.

[0040] An irrigation method for agricultural water-fertilizer integrated irrigation equipment comprises the following steps:

[0041] S1. Pour solid fertilizer into the feed pipe 20, so that the motor 22 can drive the driving worm 23 to rotate, and the driving worm gear 25 can drive the driven worm 24 to rotate, thereby driving the driven worm gear 27 and the crushing knife 28 to rotate, and the solid fertilizer in the feed pipe 20 is crushed, which can prevent the solid fertilizer from agglomerating in the feed pipe 20 and making it difficult to dissolve in water;

[0042] S2. Water is injected into the water storage tank 3 through the water injection pipe. As the water flows down, the fan plate 39 can drive the rotating rod 38 to rotate, thereby driving the winding rod 31 to rotate and wind the coil spring 32. As the coil spring 32 is wound, the connecting plate 33 can pull the baffle plate 34 to move, so that the feed port can be opened in a short time to allow solid fertilizer to enter the water storage tank 3. When the feed port is opened, as the water injection continues, the fan plate 39 is driven to rotate around the torsion spring, which can prevent the rotating rod 38 from continuing to rotate. When the water injection stops, the baffle plate 34 can be driven to move by the elastic force of the reset spring 36, so that the baffle plate 34 is reset in a short time to seal the feed port;

[0043] S3. When the transmission worm 23 rotates, the stirring shaft 5 is driven to rotate, thereby driving the stirring rod 6 and the mixing rod 7 to rotate. The interior of the water storage tank 3 is divided into a mixing chamber and an upper and lower chamber of the stirring chamber by the partition 4. Solid fertilizer and water enter the mixing chamber. The mixing rod 7 rotates to drive the solid fertilizer and water in the mixing chamber to be stirred and mixed. After the water and fertilizer are mixed, the discharge valve is opened to allow the water-fertilizer solution to enter the stirring chamber through the discharge port. The water-fertilizer solution can be stirred by the rotation of the stirring rod 6 to prevent the solid matter in the water-fertilizer solution from precipitating.

[0044] S4. When the solid fertilizer and water in the water tank 3 are dissolved, the liquid pump 9 starts working, and the water-fertilizer solution in the water tank 3 is extracted through the connecting pipe, and the water-fertilizer solution is poured into the nozzle 11 through the liquid outlet pipe 10 and sprayed out for irrigation. As the irrigation mechanism moves, the roller 15 and the rotating shaft 14 rotate, and the nozzle 11 can be driven to rotate by the special-shaped bevel gear 16 cooperating with the transmission bevel gear 17. When the special-shaped bevel gear 16 is separated from the transmission bevel gear 17, the nozzle 11 rotates under the action of gravity, so that the nozzle 11 reciprocates, thereby expanding the irrigation area of ​​the irrigation equipment and allowing the water-fertilizer solution to flow and diffuse quickly.
