Description

Technical Field

[0001] The utility model relates to the technical field of water-fertilizer integrated irrigation equipment, in particular to a novel water-fertilizer integrated irrigation device for grains. Background Art

[0002] The integrated water-fertilizer machine uses a pressure system (or natural terrain height difference) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer liquid is mixed with irrigation water through a controllable pipeline system. After the water and fertilizer are mixed, irrigation is formed through pipes, spray guns or nozzles, and the fertilizer is sprayed evenly, regularly and quantitatively on the crop development and growth areas, so that the soil in the main development and growth areas always remains loose and has an appropriate moisture content. At the same time, according to the fertilizer requirements of different crops, the soil environment and nutrient content, and the fertilizer requirements, the needs of different growth periods are designed, and water and nutrients are provided directly to crops in a regular, quantitative and proportional manner.

[0003] In order to further understand the water-fertilizer integrated irrigation technology in the prior art, after searching, the Chinese patent with announcement number: CN218735991U discloses an intelligent water-fertilizer integrated equipment, including a mixing barrel, a water storage barrel is fixed on the top of the mixing barrel, a water inlet is provided on the water storage barrel, a stirring and grinding mechanism is provided in the mixing barrel, a liquid adding component is connected to the left side of the water storage barrel, and a spray component is connected to the right side of the mixing barrel. The stirring and grinding mechanism includes a motor, which is arranged on the left side of the mixing barrel, and the output end of the motor passes through the mixing barrel and is fixed with a connecting shaft, and three connecting plates are fixed on the surface of the connecting shaft, and grinding plates are fixed at the ends of the three connecting plates, and the grinding plates are in contact with the circumferential inner wall of the mixing barrel.

[0004] After exploration and analysis, the patent has the following shortcomings in actual use: although the patent grinds solid fertilizers through the grinding plate in cooperation with the inner wall of the mixing barrel to prevent undecomposed solid fertilizers from blocking the pipeline, the grinding plate cannot completely guarantee that all solid fertilizers are ground. At the same time, the ground solid fertilizers may not be completely dissolved in water. Undissolved solid fertilizers will enter the sprinkler pipe through the pipeline and cause blockage of the sprinkler head, resulting in uneven irrigation and reduced irrigation efficiency. Utility Model Content

[0005] Aiming at the technical problem that the existing undissolved solid fertilizer will enter the spray pipe through the pipeline to cause the blockage of the spray head, resulting in uneven irrigation and reduced irrigation efficiency, the utility model provides a new water-fertilizer integrated irrigation device for grains.

[0029] The following is a further description of the present utility model in conjunction with the attached Figures 1-5 drawings.

[0030] To solve the problems existing in the background technology, the present application proposes the following technical solution: It includes a mixing tank 1, a water inlet pipe 2 is fixedly installed on the mixing tank 1, a fertilizer discharge port 27 is opened at the bottom of the mixing tank 1, a fertilizer discharge pipe 7 is fixedly connected below the fertilizer discharge port 27, an electromagnetic valve 8 is fixedly installed on the fertilizer discharge pipe 7, a feeding channel 5 is fixedly installed on the mixing tank 1, a hopper 6 is fixedly connected to the feeding channel 5, an output pipe 14 is fixedly installed on the fertilizer discharge port 27, two groups of output ports 20 are opened on the output pipe 14, and a filter screen 15 is fixedly installed in the two groups of output ports 20.

[0031] Solid fertilizers are placed in the hopper 6 and enter the interior of the mixing tank 1 through the feeding channel 5. Water is added to the mixing tank 1 through the water inlet pipe 2. The solid fertilizers are dissolved in the water in the mixing tank 1 to achieve the integration of water and fertilizer. The dissolved solid fertilizers enter the interior of the output pipe 14 through the output ports 20 along with the water, and then are discharged from the mixing tank 1 through the fertilizer discharge port 27 and the fertilizer discharge pipe 7. The fertilizer discharge pipe 7 is connected to an external spraying pipeline (not shown in the drawings). The water and fertilizer are used to irrigate and fertilize the grains through the external spraying pipeline. The filter screen 15 arranged in the output ports 20 can prevent the undissolved solid fertilizers in the water from entering the output pipe 14, thereby avoiding the blockage of the spray heads of the spraying pipeline by the undissolved solid fertilizers, and thus ensuring the watering efficiency of the integration of water and fertilizer. The electromagnetic valve 8 is provided to control the discharge of the water and fertilizer.

[0032] Furthermore, two groups of first motors 9 are fixedly installed at the bottom of the mixing tank 1, a rotating rod 10 is fixedly installed on the drive shafts of the two groups of first motors 9, and a stirring rod 11 is fixedly connected to the outer surface of the rotating rod 10.

[0033] The first motor 9 drives the rotating rod 10 to rotate, the rotating rod 10 drives the stirring rod 11 to rotate, and the stirring rod 11 stirs the solid chemical fertilizer and water added to the mixing tank 1, accelerating the dissolution rate of the solid chemical fertilizer and improving the mixing efficiency of the solid chemical fertilizer and water.

[0034] Furthermore, a first gear 12 is fixedly sleeved outside a set of rotating rods 10. A second gear 13 is engaged on one side of the first gear 12. The lower end of the second gear 13 is fixedly connected with a mounting column 21. The mounting column 21 is rotatably mounted on the top end of the output pipe 14. The lower end of the second gear 13 is also fixedly connected with a connecting rod 16. A cleaning brush 17 is fixedly mounted on the outer surface of the connecting rod 16. One side of the cleaning brush 17 away from the connecting rod 16 is in contact with the filter screen 15.

[0035] While the rotating rod 10 drives the stirring rod 11 to rotate, it also drives the first gear 12 to rotate. The first gear 12 drives the second gear 13 to rotate. The second gear 13 drives the connecting rod 16 to rotate around the output pipe 14. The connecting rod 16 drives the cleaning brush 17 to rotate around the output pipe 14. The rotation of the cleaning brush 17 cleans the filter screen 15, preventing the undissolved solid chemical fertilizer from blocking the mesh holes of the filter screen 15 and affecting the entry of the water fertilizer into the output pipe 14 for discharge, thus improving the practicability of the irrigation device.

[0036] Furthermore, a slide rail 18 is opened at the bottom of the mixing tank 1. A limiting column 19 is slidably mounted in the slide rail 18. The limiting column 19 is fixedly mounted at the bottom end of the connecting rod 16.

[0037] The cooperation of the slide rail 18 and the limiting column 19 can play a role in guiding and limiting the rotation of the cleaning brush 17 around the output pipe 14, ensuring the cleaning effect of the cleaning brush 17 on the filter screen 15.

[0038] Furthermore, two groups of rotating shafts 22 are rotatably mounted in the feed channel 5. Crushing rollers 23 are fixedly sleeved outside the two groups of rotating shafts 22. The crushing rollers 23 are arranged in the feed channel 5.

[0039] The rotation of the two groups of crushing rollers 23 can crush the solid chemical fertilizer passing through the feed channel 5, reducing the particle size of the solid chemical fertilizer, facilitating the subsequent dissolution of the solid chemical fertilizer in water, and improving the mixing efficiency of the solid chemical fertilizer and water.

[0040] Furthermore, a second motor 24 is arranged outside the feed channel 5. The drive shaft of the second motor 24 is fixedly connected with one group of rotating shafts 22. Transmission wheels 25 are fixedly mounted outside the two groups of rotating shafts 22. A belt 26 is sleeved outside the two groups of transmission wheels 25.

[0041] The second motor 24 drives the rotation of the rotating shaft 22, and the rotating shaft 22 drives another set of rotating shafts 22 to rotate synchronously through the transmission wheels 25 and the belt 26, so as to drive the crushing rollers 23 to rotate by the two sets of rotating shafts 22 to crush solid chemical fertilizers.

[0042] Furthermore, three sets of legs 3 are fixedly installed at the bottom of the mixing tank 1, and the bottom ends of the three sets of legs 3 are fixedly connected with mounting plates 4.

[0043] The three sets of legs 3 support the mixing tank 1.

The two sets of rotating shafts 22 drive the crushing rollers 23 to rotate to crush the solid chemical fertilizers. The crushed solid chemical fertilizers enter the interior of the mixing tank 1 through the feed channel 5. The water inlet pipe 2 adds water to the mixing tank 1. The first motor 9 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the stirring rod 11 to rotate. The stirring rod 11 stirs the solid chemical fertilizers and water added to the mixing tank 1 to accelerate the dissolution rate of the solid chemical fertilizers. The filter screen 15 provided in the output port 20 can prevent the undissolved solid chemical fertilizers in the water from entering the output pipe 14. While the rotating rod 10 drives the stirring rod 11 to rotate, it also drives the first gear 12 to rotate. The first gear 12 drives the second gear 13 to rotate, and the second gear 13 drives the connecting rod 16 to rotate around the output pipe 14. The connecting rod 16 drives the cleaning brush 17 to rotate around the output pipe 14, and the cleaning brush 17 rotates to clean the filter screen 15 to prevent the undissolved solid chemical fertilizers from blocking the mesh holes of the filter screen 15. The dissolved solid chemical fertilizers enter the interior of the output pipe 14 with the water through the output port 20, and then are discharged from the mixing tank 1 through the fertilizer discharge port 27 and the fertilizer discharge pipe 7. The fertilizer discharge pipe 7 is connected to the external spray pipe, and the water and fertilizer are used to irrigate and fertilize the grains through the external spray pipe.
