There are many drawbacks to this fertilization method. First of all, the process of opening furrows requires a lot of time and labor, increasing the agricultural production cost. Taking traditional manual furrow fertilization as an example, when operating on large areas of farmland, the efficiency of manual furrow opening is extremely low, a large amount of manpower needs to be invested, and the labor intensity is high. It not only takes a long time but also may affect the timeliness of fertilization due to insufficient manpower, thus affecting the growth cycle and harvest of crops.

Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments.

[0026] Embodiment 1, as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a pneumatic no-tillage fertilization device is provided. The output end of the fertilizer storage bin 1 is connected to a fertilizer supply pipe 2. A fertilizer valve 3 is installed inside the fertilizer supply pipe 2. The output end of the fertilizer supply pipe 2 is connected to a high-pressure gas chamber 4. The bottom output end of the high-pressure gas chamber 4 is connected to a fertilization pipe 5. A launch valve 6 is installed inside the fertilization pipe 5. One side of the top of the high-pressure gas chamber 4 is connected to a high-pressure gas delivery pipe 7. A high-pressure gas control valve 8 is installed inside the high-pressure gas delivery pipe 7. The input end of the high-pressure gas delivery pipe 7 is connected to a high-pressure gas storage chamber 9. An air compressor 10 is installed at the bottom input end of the high-pressure gas storage chamber 9. A controller 11 is installed at the top of the high-pressure gas storage chamber 9. The controller 11 is connected to the fertilizer valve 3, the launch valve 6, the high-pressure gas control valve 8, and the air compressor 10. The controller 11 is connected to a pressure sensor 12 and a flow sensor. The pressure sensor 12 is installed at the inner top of the high-pressure gas chamber 4. The flow sensor is installed at the output end of the fertilizer supply pipe 2.

[0027] In this embodiment, during use, the controller 11 controls the fertilizer valve 3, the launch valve 6, the high-pressure gas control valve 8, and the air compressor 10. By opening the fertilizer valve 3, the fertilizer storage bin 1 outputs fertilizer into the fertilizer supply pipe 2. The fertilizer enters the high-pressure gas chamber 4 through the fertilizer supply pipe 2. The flow sensor at the output end of the fertilizer supply pipe 2 monitors the fertilizer flowing into the high-pressure gas chamber 4. When it detects that the amount of fertilizer reaches the required quantity, the flow sensor sends a signal to the controller 11, causing the controller 11 to control the fertilizer valve 3 to close. Then, the controller 11 controls the high-pressure gas control valve 8 to open, and at the same time, the air compressor 10 starts. After the air compressor 10 generates high-pressure gas, it inputs the high-pressure gas into the high-pressure gas storage chamber 9 for storage. When the high-pressure gas control valve 8 is opened, the high-pressure gas is output from the high-pressure gas delivery pipe 7 into the high-pressure gas chamber 4. The pressure sensor 12 synchronously detects the air pressure value inside the high-pressure gas chamber 4. When the pressure sensor 12 detects that the air pressure inside the high-pressure gas chamber 4 reaches a certain pressure, it sends a signal to the controller 11, causing the controller 11 to control the high-pressure gas control valve 8 to close. Finally, the controller 11 controls the launch valve 6 to open, and through the thrust generated by the air pressure, the fertilizer inside the high-pressure gas chamber 4 is launched at a certain initial velocity and output through the guidance of the fertilization pipe 5, so that the fertilizer can be directly injected into the soil to achieve the no-tillage effect.

[0028] Among them, according to different farmland operation requirements, the specifications and parameters of each component can be reasonably selected. The capacity of the fertilizer storage bin can be designed according to the fertilization operation area and the amount of fertilizer used to meet the needs of continuous operation. The controller can adopt a programmable logic controller (PLC), and by writing corresponding control programs, precise control of each valve can be achieved. During use, the operator sets the fertilization parameters according to the crop type, soil conditions, etc. After starting the device, the device can automatically complete the fertilization operation according to the set program.

[0029] Among them, according to the crop category (such as corn, onion, etc.), the fertilizer requirement characteristics and the soil environment, the controller 11 can control the air pressure value in the high-pressure gas chamber 4 to achieve the control of the fertilization depth and the precise adjustment of the quantity. For example, for corn with deeper roots, a higher air pressure can be set to shoot the fertilizer into deeper soil layers; while for onions with shallower roots, the air pressure can be reduced to achieve shallow soil layer fertilization.

[0030] Among them, during installation, it can be installed on modern agricultural machinery. By being assembled and used with modern agricultural machinery, it can quickly meet the requirements of precision agriculture and mechanized agriculture.

When in fixed use, the limit pins 33 are taken out. The bottom plate 29 and the positioning cones 30 drive the guide rods 28 to move downward along the guide seat 27 under the action of gravity. When the limit jacks 32 on the upper side of the guide rods 28 move out of the bottom of the guide seat 27, the limit pins 33 are inserted for limiting, so as to ensure the fixed support of the fixing component 26 for the moving mechanism 20.

The first bevel gear 35 drives the meshed second bevel gear 36. The second bevel gear 36 drives the rotating shaft 37 to rotate on the mounting plate 21. The top of the rotating shaft 37 drives the rotating rod 38. The rotating rod 38 drives the dispersing rods 39 to rotate in the fertilizer storage bin 1, so as to enable the dispersing rods 39 to disperse the agglomerated materials generated in the fertilizer storage bin 1 and improve the subsequent fertilization effect.
