Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a portable drip irrigation plot experimental fertilizer applicator. Background Technology

[0002] Integrated water and fertilizer management is a commonly used technology in agricultural production. As a precision fertilization technique, it is increasingly being applied to agricultural production. However, for drip irrigation experimental fields, the area is relatively small, the drip irrigation test treatment is extensive, and the amount of fertilizer applied is very small. Existing precision agricultural fertilization uses pipeline water pressure power fertilization. The water pressure in the main pipe of the existing small-area fertilizer tank is unstable, resulting in uneven irrigation and fertilization. This leads to inconsistent crop growth in the experimental field and affects the accuracy of the experimental results. In addition, when using the current fertilizer applicator, the outlet end is not easy to clean due to long-term use, which can cause fertilizer to accumulate on the filter screen, or cause difficult-to-clean stains to clog the filter screen. Therefore, to address the above problems, this application proposes a portable drip irrigation small-area experimental fertilizer applicator. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1-3This utility model provides an embodiment of a portable drip irrigation plot experimental fertilizer applicator, comprising a fertilizer tank 4 and a base 15. The fertilizer tank 4 is installed on the top of the base 15, and a lid 9 is provided on the top of the fertilizer tank 4. A mixing component 17 is provided inside the fertilizer tank 4. The fertilizer tank 4 can mix water and fertilizer. The fertilizer tank 4 is circular to facilitate stirring the water and fertilizer to ensure uniform mixing. The lid 9 can be unscrewed to remove the mixing component 17 for cleaning. It is suitable for mixing different water and fertilizers, avoiding different components from affecting the fertilizer state. It facilitates uniform nutrient distribution to crops in the experimental plot, achieving uniform nutrient distribution and balanced growth of crops in the experimental plot, and ensuring that the crops in the experimental plot can obtain accurate experimental data and conclusions. The mixing component 17 includes a bottom trough 10, stirring rods 5, a hopper 7, and a main rod 18. The main rod 18, stirring rods 5, and bottom trough 10 are all provided with evenly distributed small holes and are hollow. The bottom trough 10 is installed at the lower end of the main rod 18. Multiple stirring rods 5 are evenly distributed on both sides of the main rod 18. The bottom trough 10 is arranged in an equilateral triangle shape, and the stirring rods 5 are parallel to the top edges of both sides of the bottom trough 10. The main rod 18 is rotatably connected via bearings and passes through the middle of the cover 9. The hopper 7 is installed at the top of the main rod 18 and is above the cover 9. Fertilizer is poured into the main rod 18, bottom trough 10, and stirring rods 5 through the hopper 7. The main rod 18 is rotated by the handle 8, allowing the fertilizer to come into contact with water. Simultaneously, the water flow and fertilizer move together, achieving thorough and uniform dissolution of the fertilizer in the water. The pump body 16 delivers... When discharging fertilizer, the water and fertilizer are evenly distributed, ensuring the uniformity of the fertilization experiment in the experimental field. Even fertilization ensures that the crops in the experimental field grow in a uniform manner, which facilitates accurate statistical analysis of experimental data. When fertilizer is fed into the main rod 18 through the hopper 7, the fertilizer first falls into the bottom trough 10. The equilateral triangular design of the bottom trough 10 ensures that the fertilizer is evenly piled up. Then, the fertilizer falls from the main rod 18 into the stirring rod 5. The downward-pointing design of the stirring rod 5 ensures that the fertilizer is piled up inside the stirring rod 5. After the main rod 18 is full of fertilizer, the main rod 18 is rotated by the handle 8. The main rod 18 drives the stirring rod 5 and the bottom trough 10 to stir the water. The water flows into the fertilizer through the small holes to dissolve the fertilizer. At the same time, the mixing and stirring ensures that the water and fertilizer are fully and evenly integrated. Then, combined with the output hose 12 of the pump body 16, the crops in the experimental field are evenly irrigated with water and fertilizer. A filter assembly 19 is provided on one side of the bottom of the fertilizer tank 4. The filter assembly 19 is used to filter water and fertilizer impurities in the fertilizer tank 4. The filter assembly 19 can ensure the filtration of impurities inside the water and fertilizer, and realize the normal and long-term operation of the equipment. The base 15 is also equipped with a pumping assembly, which includes a pump body 16. The pump body 16 is connected to the bottom of the filter assembly 19 through a connecting pipe 13. The bottom of the filter assembly 19 extends through into the base 15. A hose 12 is connected to one side of the pump body 16. The pumping assembly can deliver water and fertilizer into the hose 12 and spray it onto the experimental field. A nozzle is provided at the end of the hose 12 away from the base 15.

[0019] A handle 6 is provided on one side of the fertilizer box 4. The handle 6 can push the base 15 and the fertilizer box 4. The base 15 is equipped with wheels to facilitate its movement, making the experimental fertilization equipment portable for experimental fields. Handles 6 can also be provided on both sides of the fertilizer box 4 to facilitate its carrying and make it suitable for water and fertilizer spraying in experimental fields.

[0020] The mixing assembly 17 also includes a throttle 8, which is fixedly connected to the top of the main rod 18 and positioned directly above the cover 9. The throttle 8 is L-shaped and its end away from the main rod 18 is parallel to the main rod 18. The throttle 8 rotates the main rod 18.

[0021] A water outlet 3 is provided on one side of the bottom of the fertilizer tank 4, and wastewater can be discharged through the water outlet 3 when washing the fertilizer tank 4.

[0022] The flexible hose 12 passes through the base 15, and a fixing block 11 is provided at the point where the flexible hose 12 passes through the base 15. The fixing block 11 can fix the flexible hose 12 to the side wall of the base 15.

[0023] The pumping assembly also includes a battery 1 and a switch 2. The switch 2 is embedded in the side wall of the base 15, the battery 1 is disposed inside the base 15, and the pump body 16 is installed in the middle of the base 15. The battery 1 and the switch 2 are electrically connected, the switch 2 and the pump body 16 are electrically connected, and the battery 1 and the pump body 16 are electrically connected through an inverter. The filter assembly 19 includes a housing 25, a filter cloth 14, an outer sliding sleeve 20, an inner filter screen 24, a skirt 21, a spring 22, and air holes 23. The outer sliding sleeve 20 is set with... The outer sliding sleeve 20 is fixedly connected to the bottom of the inner filter 24 with a skirt 21. Springs 22 are evenly distributed at the bottom of the skirt 21, and are in a compressed state and fixedly connected to the inner bottom of the housing 25. Evenly distributed air holes 23 are provided at the bottom of the inner filter 24, below the skirt 21. Both the outer sliding sleeve 20 and the inner filter 24 have evenly distributed small holes that are staggered. The skirt 21 and the housing 25 slide relative to each other. The sealed design facilitates the downward movement of the outer sliding sleeve 20 driven by the skirt 21. In actual use, when the pump body 16 draws in water and fertilizer, the air vent 23 can use negative pressure to draw the skirt 21 downward. At this time, the outer sliding sleeve 20 moves downward, and the small holes between the outer sliding sleeve 20 and the inner filter screen 24 overlap. The water and fertilizer in the fertilizer tank 4 can enter the pump body 16 through the filter cloth 14 and then be output from the hose 12 to achieve water and fertilizer spraying. When the pump body 16 stops, the outer sliding sleeve 20 is squeezed by the spring 22 to close the inner filter screen 24. This design ensures that the outer sliding sleeve 20 can move outside the inner filter screen 24 each time, preventing water and fertilizer from precipitating out of the inner filter screen 24 or preventing dirt from the water from accumulating inside the inner filter screen 24. With long-term normal use, it is not easy to clog the filter assembly 19. When the pump body 16 is working, the switch 2 is turned on, and the battery 1 supplies power to the pump body 16, which then supplies water and fertilizer mixture drawn from the filter assembly 19.

[0024] The filter cloth 14 is located at the bottom of the fertilizer tank 4, and can initially filter particulate impurities on the surface of the water and fertilizer. The housing 25 is fixedly connected to the base 15 and the bottom wall of the fertilizer tank 4 to achieve water and fertilizer filtration.

[0025] Working principle: When the fertilizer applicator is actually used in the drip irrigation plot test, fertilizer is poured into the main rod 18, bottom trough 10 and stirring rod 5 through the hopper 7. The main rod 18 is rotated by the handle 8, so that the fertilizer can come into contact with the water. At the same time, the water flow and fertilizer move with each other, so that the fertilizer is fully and evenly dissolved in the water. When the pump body 16 outputs water and fertilizer, it will be very even, ensuring the uniformity of the plot fertilization test. Uniform fertilization can ensure the uniformity of crop growth in the test field, which is convenient for accurate statistical data collection in the test field. Pump body 16 draws in water and fertilizer. The air vent 23 can use negative pressure to pull the skirt 21 downwards. At this time, the outer sliding sleeve 20 moves downwards, and the small holes between the outer sliding sleeve 20 and the inner filter screen 24 overlap. The water and fertilizer in the fertilizer tank 4 can enter the pump body 16 through the filter cloth 14 and then be output from the hose 12 to achieve water and fertilizer spraying. When pump body 16 stops, the outer sliding sleeve 20 is squeezed by spring 22 to close the inner filter screen 24. This setting can ensure that the outer sliding sleeve 20 can move outside the inner filter screen 24 each time, avoiding water and fertilizer precipitation on the inner filter screen 24, or preventing dirt from the water body from being contaminated and deposited inside the inner filter screen 24. With long-term normal use, it is not easy to clog the filter assembly 19. When pump body 16 is working, switch 2 is turned on, and battery 1 supplies power to pump body 16. Pump body 16 supplies water and fertilizer mixture drawn from filter assembly 19.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
