[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a fertilization device for crop planting, including a discharge pipe 4, a crushing chamber 11 at the lower end of the discharge pipe 4, a plurality of ribs 16 on the inner side wall of the crushing chamber 11, a motor 20 on the inner bottom wall of the crushing chamber 11, a blade assembly 18 fixedly mounted at the output end of the motor 20, a filter screen 17 on the inner side wall of the crushing chamber 11, the filter screen 17 being positioned between the motor 20 and the blade assembly 18, the ribs 16 being positioned above the filter screen 17, the ribs 16 and the blade assembly 18 not interfering with each other, a feeder 10 on the lower side of the crushing chamber 11, and a fertilizer spreading disc 8 fixedly mounted on the right side of the feeder 10.
[0025] In this embodiment, Figure 1 The orientation is indicated by front, back, left, and right. The upper part of the discharge pipe 4 is a flexible hose. Specifically, when using this device, fertilizer granules enter the crushing chamber 11 through the discharge pipe 4. The motor 20 starts and drives the blade assembly 18 to rotate, crushing the fertilizer granules. At the same time, under the rapid rotation of the blade assembly 18, the fertilizer granules are thrown onto the ribs 16 on the inner wall of the crushing chamber 11, which improves the crushing efficiency of the fertilizer granules.
[0026] The crushed fertilizer sinks into the lower part of the crushing chamber 11 through the filter screen 17, and is drawn by the feeder 10 to accelerate the sinking speed of the crushed fertilizer. The crushed fertilizer is then blown at high speed into the fertilizer spreading disc 8, and the fertilizer is spread onto the soil through the fertilizer spreading disc 8. This improves the situation where the dissolution rate of granular fertilizer in the soil is relatively slow, and it may not be able to provide enough nutrients in time when crops urgently need nutrients.
[0027] Reference Figure 1 , Figure 2 and Figure 4 A storage bin 1 is fixedly installed at one end of the discharge pipe 4. A partition 3 is fixedly connected between the front and rear inner walls of the storage bin 1, dividing the interior of the storage bin 1 into two areas. Inlets 2 are provided on both the left and right sides of the partition 3, with the inlets 2 located on the upper side of the storage bin 1. The outer wall of the discharge pipe 4 passes through the front side of the storage bin 1. Two discharge pipes 12 are installed inside the lower end of the discharge pipe 4. A partition 13 is installed inside the discharge pipe 4, dividing the interior of the discharge pipe 4 evenly. The system is divided into two areas. Two feed pipes 12 are respectively set on the left and right sides of the partition 2 13, and the rear side of the partition 2 13 is set on the front side of the partition 1 3. A connecting pipe 2 14 is fixedly set on the lower side of the feed pipe 12. The outer wall of the connecting pipe 2 14 passes through the upper side of the crushing chamber 11. A paddle 19 is rotatably connected inside the connecting pipe 2 14. A connecting rod 15 is fixedly connected to one side of the paddle 19. An adjustment button 7 is fixedly connected to one end of the connecting rod 15. The adjustment button 7 is set on the side wall of the discharge pipe 4.
[0028] Specifically, partition 2 13 is made of rubber. When using this device, partition 1 3 divides the internal space of storage tank 1 into two parts, and different types of fertilizers are poured into storage tank 1 through two inlets 2. Through partition 1 3 and partition 2 13, two types of fertilizers can simultaneously enter different areas inside the discharge pipe 4.
[0029] Two types of fertilizer enter different discharge pipes 12 through discharge pipe 4, and then enter connecting pipe 2 14. When the ratio of the two fertilizers is different, rotating the adjustment button 7 drives the connecting rod 15, which in turn drives the lever 19; through the rotational connection between lever 19 and connecting pipe 2 14, the gap between lever 19 and connecting pipe 2 14 is different, thereby adjusting the flow rate of fertilizer inside connecting pipe 2 14, thus achieving the adjustment of the ratio of the two fertilizers.
[0030] Reference Figure 1 Measuring tubes 5 are provided on both the left and right sides of the discharge pipe 4. The outer wall of the measuring tube 5 passes through the side wall of the discharge pipe 4. The measuring tube 5 is made of plexiglass.
[0031] Specifically, during fertilization, the remaining amount of fertilizer in the storage tank 1 is determined by observing the amount of fertilizer remaining inside the measuring tube 5, thus realizing the function of the device reminding users to add fertilizer.
[0032] Reference Figure 1 and Figure 5 A switch 6 is installed on the side wall of the discharge pipe 4. The switch 6 is electrically connected to the motor 20 and the feeder 10.
[0033] Specifically, when using this device, the operation of the motor 20 and the feeder 10 is controlled by the switch 6, thereby realizing the fertilization control function of the device.
[0034] Reference Figure 1 The feed end of the feeder 10 passes through the lower side of the crushing chamber 11. A connecting pipe 9 is fixedly installed on the right side of the feeder 10, and the right side of the connecting pipe 9 is fixedly installed on the left side of the fertilizer spreading disc 8.
[0035] Specifically, the crushed and mixed fertilizer enters the fertilizer spreading disc 8 through the connecting pipe 9, and is blown onto the soil outside by the airflow from the pump 10, thus realizing the fertilization function of the device.
[0036] Working principle: Different types of fertilizers are poured into the storage box 1 through two inlets 2; through partition 1 3 and partition 2 13, the two types of fertilizers enter different areas inside the discharge pipe 4 at the same time, and then enter the discharge pipe 12.
[0037] When the ratio of two fertilizers is different, rotating the adjustment button 7 drives the connecting rod 15, which in turn drives the paddle 19; and through the rotational connection between the paddle 19 and the second connecting tube 14, the flow rate of the fertilizer inside the second connecting tube 14 is adjusted by the different gap sizes between the paddle 19 and the second connecting tube 14, thereby realizing the adjustment of the ratio of different fertilizers.
[0038] Then, the fertilizer enters the crushing chamber 11 through the connecting pipe 14. The motor 20 and the feeder 10 are started by the switch 6, which drives the blade assembly 18 to rotate and crush the fertilizer particles. At the same time, under the rapid rotation of the blade assembly 18, the fertilizer particles are directed onto the ribs 16 on the inner wall of the crushing chamber 11, which improves the crushing efficiency of the fertilizer particles.
[0039] The crushed fertilizer sinks into the lower part of the crushing chamber 11 through the filter screen 17, and is drawn down by the feeder 10 to accelerate the sinking speed. Then, it enters the fertilizer spreading disc 8 through the connecting pipe 9 and is blown onto the outside soil. When the remaining amount of fertilizer is not much as observed through the measuring tube 5, fertilizer can be added. This improves the situation where the dissolution rate of granular fertilizer in the soil is relatively slow, and it may not be able to provide enough nutrients in time when crops urgently need them.
[0040] 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.
