Fertilizers are loaded into the material storage box 2, and the opening and closing of the feeding pipe 3 can be controlled by a valve 4. The valve 4 adopts a rotary valve or a sliding valve structure to achieve precise flow control. After the valve 4 is opened, the fertilizers naturally fall out of the feeding pipe 3 due to the action of gravity and fall into the powder flowmeter 5. The valve 4 is installed on the surface of the feeding pipe 3. The feeding pipe 3 can be made of corrosion-resistant materials such as stainless steel or plastic to ensure that it is not easily damaged during long-term use.

[0026] Please refer to Figures 1-5 , a laser distance sensor 6 is fixedly installed on the surface of the powder flowmeter 5. A connecting plate 7 is fixedly installed on the side surface of the laser distance sensor 6. The material of the connecting plate 7 is ferritic stainless steel.

The connecting plate 7 is installed on the powder flowmeter 5 by welding or bolt fixing to ensure its stability and installation accuracy. A sliding plate 8 is penetrated through the side surface of the connecting plate 7. The sliding plate 8 is slidably connected to the connecting plate 7. The sliding plate 8 can be realized by a chute structure or a linear bearing. One end of the sliding plate 8 is fixedly installed with a cover plate 9. The cover plate 9 is attached to the bottom surface of the laser distance sensor 6. Magnets A 10 and B 11 are fixedly installed on the surface of the sliding plate 8. The magnets A 10 and B 11 are fixed on the sliding plate 8 by screws to ensure their accurate positions and firm installations.

[0027] Embodiment 2

[0028] Please refer to Figures 4-5, a fixing mechanism is provided on the bottom surface of the support frame 1. The fixing mechanism includes a base frame 14, and the base frame 14 is fixedly installed on the bottom surface of the support frame 1. The base frame 14 and the support frame 1 can be connected by a bolt fixing method to ensure its stability. A vertical rod 15 is provided through the top surface of the base frame 14. The sliding connection between the vertical rod 15 and the base frame 14 can adopt a sliding bearing, which not only ensures the smooth sliding of the vertical rod 15 but also reduces friction and improves the service life. The vertical rod 15 is slidably connected to the base frame 14. A bottom plate 16 is fixedly installed at the bottom end of the vertical rod 15. A plug post 17 is fixedly installed on the bottom surface of the bottom plate 16.

The return spring 19 is made of high-strength steel and has good elasticity and durability to ensure that a reliable return force can still be provided after long-term use. One end of the return spring 19 is fixedly connected to the bottom plate 16, and the other end of the return spring 19 is fixedly connected to the base frame 14.

[0029] Working principle: The material storage box 2 is used to load fertilizers. The opening and closing of the feeding pipe 3 can be controlled through the valve 4. After the valve 4 is opened, the fertilizers naturally fall out from the feeding pipe 3 due to the action of gravity, fall into the powder flowmeter 5, and then fall out from the powder flowmeter 5 and enter the planting pits on the ground, thus completing fertilization. In this way, multi-layer fertilization is carried out repeatedly. During this process, the powder flowmeter 5 can measure the amount of fertilization, so as to record the amount of fertilization for each layer. And through the laser ranging sensor 6, the fertilization depth can be recorded by ranging. After saving the fertilization data in this way, it is convenient for subsequent calculation and statistics. At the same time, when the laser ranging sensor 6 is not in use, the staff can push the slide plate 8. At this time, the slide plate 8 slides inside the connecting plate 7. Then the slide plate 8 drives the cover plate 9 to move until the cover plate 9 covers the bottom surface of the laser ranging sensor 6. At this time, the laser head of the laser ranging sensor 6 can be protected. And at this time, the magnet B11 can resist the connecting plate 7. At this time, due to the action of magnetic force, the magnet B11 can attract the connecting plate 7 made of ferritic stainless steel, so as to limit the position of the cover plate 9. And when the laser ranging sensor 6 needs to be used, the staff only needs to pull the slide plate 8 outwards. Then the slide plate 8 can drive the cover plate 9 to move until the cover plate 9 leaves the bottom surface of the laser ranging sensor 6. At this time, the laser ranging sensor 6 can be used normally. And at this time, the magnet A10 can resist the connecting plate 7. At this time, the magnet A10 attracts the connecting plate 7, and the open state of the cover plate 9 can be maintained. The utility model accurately measures the amount of fertilization through the powder flowmeter 5, can record the amount of fertilization for each layer, ensures the uniformity and accuracy of fertilization, avoids over-fertilization or under-fertilization, and improves the fertilizer utilization efficiency. At the same time, the laser ranging sensor 6 can measure and record the fertilization depth, which is convenient for subsequent data analysis and statistics. This makes the fertilization process more scientific and refined, and can adjust the fertilization strategy according to the needs of different plants. And when the laser ranging sensor 6 is not in use, through the mechanical structure design of the slide plate 8 and the cover plate 9, the laser head of the laser ranging sensor 6 can be protected to avoid damage from the external environment, improve the service life and reliability of the sensor. The design of the slide plate 8 and the cover plate 9 enables the staff to easily switch the working state of the laser ranging sensor 6, with simple operation and no complex operation steps, improving the convenience of use. When fertilizing, if the soil is relatively soft, the staff can step on the pedal 18. Then the pedal 18 can drive the vertical rod 15 to move downward. Then the vertical rod 15 drives the bottom plate 16 to move downward. Then the bottom plate 16 drives the insertion post 17 to move downward until the insertion post 17 is inserted into the ground. At this time, the position of the utility model can be stabilized through the insertion post 17, so as to ensure the accuracy of fertilization. And after fertilization is completed, only need to kick the pedal 18 upward until the insertion post 17 leaves the ground. Then through the pulling force of the reset tension spring 19, the reset tension spring 19 pulls the bottom plate 16 upward, so that the insertion post 17 always remains in a state of leaving the ground. In the utility model, when the soil is relatively soft, the insertion post 17 is inserted into the ground by stepping on the pedal 18.It can stabilize the fertilizing device, prevent the device from moving or tilting during the fertilizing process, and ensure the accuracy of the fertilizing position and depth. When the plug post 17 is not in use, the reset tension spring 19 can pull the bottom plate 16 and the plug post 17 away from the ground, preventing the plug post 17 from causing unnecessary damage to the ground and other objects. At the same time, it also reduces the resistance of the equipment during movement, enabling the present utility model to be applicable to various terrains and soil conditions, especially soft soil environments, increasing the applicable range of the fertilizing device, and improving the reliability and stability of the fertilizing operation.
