Description

Technical Field

[0001] This invention relates to the field of soil conditioner spraying equipment, specifically to a soil conditioner spraying equipment for saline-alkali land improvement. Background Technology

[0002] The soil amendment application equipment for saline-alkali land improvement is a special machine designed for the ecological restoration of saline-alkali land. It improves the soil by mechanized application of the amendment. Its core value lies in the precise, uniform and efficient application of the amendment to the soil. Compared with traditional manual operation, it can greatly improve the treatment effect and reduce the cost.

[0003] In existing technologies, most soil amendment spraying equipment is fixed-point operation with a fixed spraying range. When the spraying range for soil amendment is large, it requires frequent manual adjustment of the position, which leads to frequent interruptions of operation, low efficiency, and high labor costs, making it difficult to meet the needs of large-scale treatment. Summary of the Invention

[0004] The purpose of this invention is to address the problem that most soil amendment spraying equipment for saline-alkali land improvement operates at fixed points with a fixed spraying range. This results in frequent manual adjustments to the spraying location when the spraying range for saline-alkali land improvement is large, leading to frequent work interruptions, low efficiency, high labor costs, and difficulty in meeting the needs of large-scale treatment. Therefore, this invention proposes a soil amendment spraying equipment for saline-alkali land improvement.

[0005] The objective of this invention can be achieved through the following technical solutions: A soil conditioner application device for saline-alkali land includes a workbench and tracks.

[0007] In a preferred embodiment of the present invention, a double-sided rack is fixedly connected to the top of the outer wall of the workbench via a connecting plate; a set of nozzles are all rotatably and sealed on the outer wall of the output pipe; a third gear is fixedly connected to the outer wall of a set of nozzles; and the third gear meshes with the double-sided rack.

[0008] In a preferred embodiment of the present invention, a set of rotating rods is rotatably connected to the outer wall of the output pipe; a square block is provided on the outer wall of the set of rotating rods; a set of striking rods is fixedly connected to the outer wall of the square block, and multiple sets of striking rods are respectively matched with a set of nozzles; a fourth gear is fixedly connected to the outer wall of each set of rotating rods, and the set of fourth gears meshes with a double-sided rack; a set of circular through grooves is opened on one side of the outer wall of the striking rod.

[0009] In a preferred embodiment of the present invention, the outer wall of the rotating rod is provided with a sliding groove; the inner wall of the square block is slidably connected to the inner wall of the sliding groove; the outer wall of the rotating rod is rotatably connected to a reciprocating rod through the square block, and the reciprocating rod and the square block are in a reciprocating connection relationship; a fifth gear is fixedly connected to one end of the outer wall of the reciprocating rod; a set of fifth annular racks is fixedly connected to the outer wall of the output pipe through a set of fixing rods; the set of fifth gears respectively meshes with the set of fifth annular racks.

[0010] In a preferred embodiment of the present invention, a circular rod is fixedly connected to the top of the outer wall of the output tube; a stirring rod is rotatably connected to the bottom of the inner wall of the storage tank; a set of stirring plates is fixedly connected to the outer wall of the stirring rod; a pair of sprockets are fixedly connected to the outer walls of both the stirring rod and the circular rod, and the pair of sprockets are connected by a chain.

[0011] In a preferred embodiment of the present invention, a set of auxiliary rods is rotatably connected to the outer wall of the circular rod; a set of fan blades is fixedly connected to the outer wall of the auxiliary rods; a sixth gear is fixedly connected to the outer wall of each set of auxiliary rods; a sixth annular rack is fixedly connected to the top of the outer wall of the connecting plate through a connecting rod; and each set of sixth gears meshes with the sixth annular rack.

[0012] In a preferred embodiment of the present invention, a pair of vibrating rods are rotatably connected to the outer wall of the storage tank via a pair of square blocks; an eighth gear is fixedly connected to the outer wall of both the pair of vibrating rods and the stirring rod, and a set of eighth gears mesh with each other; a set of vibrating balls is fixedly connected to the outer wall of the vibrating rod via a set of flexible rods; the vibrating balls are matched with the storage tank.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The amelior is delivered to the output pipe by the pump on the workbench. When it is sprayed out through the nozzle, the motor drives the rotating shaft to rotate, which in turn drives the drive shaft to rotate through sprocket one and chain one. This causes a pair of drive wheels to rotate in the track, moving the workbench. At this time, a set of sliding support plates is responsible for supporting the workbench and cleaning impurities in the track. The nozzle sprays the amelior while moving with the workbench, allowing this application to continuously carry out large-area operations, expanding the spraying range of saline-alkali land improvement, thus eliminating the need for manual labor and work interruption, reducing costs while improving work efficiency, and also making the amelior distribution more uniform.

[0014] 2. As the nozzle rotates with the output pipe, the third gear on the nozzle rotates accordingly. Since all three third gears mesh with the double-sided rack, the nozzle drives the third gear to rotate, which in turn causes the double-sided rack to rotate. This results in the nozzle rotating while revolving around the infusion pipe, so that the droplets sprayed from the nozzle are no longer fixed-pointing fan-shaped areas, but dynamically rotating scattering cones. When countless such dynamic scattering cones are superimposed on the large circumference formed by the revolution, the small patches of land within the spraying area are repeatedly covered by droplets from different angles and time points, eliminating the microscopic blind spots that are difficult to avoid with traditional spraying. This achieves uniform coverage from macroscopic width to microscopic particles. Furthermore, the nozzle's rotation applies a tangential tearing force to the droplets just sprayed from the nozzle, breaking larger droplets into finer particles, i.e., secondary atomization. Finer droplets mean a larger specific surface area, which can be more evenly adsorbed onto the surface of saline-alkali soil particles or vegetation stems and leaves. With the same amount of pesticide, this significantly improves the utilization rate of the amendment and reduces waste. Attached Figure Description

Detailed Implementation

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please see Figures 1-9As shown, a soil conditioner application device for saline-alkali land includes a workbench 1 and tracks 2. A pump body 3 is mounted on the top of the outer wall of the workbench 1. An output pipe 4 is provided at the output end of the pump body 3. A set of nozzles 5 is mounted on the outer wall of the output pipe 4. A set of sliding support plates 6 is fixedly connected to the bottom of the outer wall of the workbench 1, and the outer walls of the sliding support plates 6 are slidably connected to the inner walls of a pair of tracks 2. A drive shaft 7 is rotatably connected to the bottom of the outer wall of the workbench 1 via a connecting block. Drive wheels 8 are fixedly connected to both ends of the outer wall of the drive shaft 7, and a pair of drive wheels 8 are respectively arranged within a pair of tracks 2. A motor 9 is fixedly connected to the top of the outer wall of the workbench 1 via a fixing block. A rotating shaft 10 is provided at the output end of the motor 9. The outer walls of the rotating shaft 10 and the drive shaft 7 are... A sprocket 11 is fixedly connected, and a pair of sprockets 11 are connected by a chain 12. The pump body 3 on the workbench 1 delivers the soil conditioner to the output pipe 4. When it is sprayed out through the nozzle 5, the motor 9 drives the rotating shaft 10 to rotate, which in turn drives the drive shaft 7 to rotate through the sprockets 11 and the chain 12. This causes a pair of drive wheels 8 to rotate in the track 2, moving the workbench 1. At this time, a set of sliding support plates 6 are responsible for supporting the workbench 1 and cleaning the impurities in the track 2. The nozzle 5 sprays the soil conditioner while moving with the workbench 1, allowing the application to continuously carry out large-area operations, increasing the spraying range of saline-alkali land improvement, thus eliminating the need for manual labor and work interruption, reducing costs while increasing work efficiency, and making the soil conditioner distribution more uniform.

[0020] The bottom of the outer wall of the output pipe 4 is sealed and rotatably mounted at the output end of the pump body 3; a first bevel gear 13 is fixedly connected to the outer wall of the output pipe 4; a second bevel gear 14 is fixedly connected to one end of the outer wall of the rotating shaft 10, and the first bevel gear 13 and the second bevel gear 14 mesh with each other; a storage tank 15 is provided at the top of the outer wall of the workbench 1; the storage tank 15 is connected to the pump body 3 through a connecting pipe; each set of nozzles 5 is equipped with an electric control valve. When the pump body 3 delivers the improver in the storage tank 15 to the nozzle 5 for spraying and moving operation, the motor 9 simultaneously drives the second bevel gear 14 to rotate through the rotating shaft 10. Because the first bevel gear 13 and the second bevel gear 14 mesh with each other, the second bevel gear 14 drives the first bevel gear 14 to rotate. A bevel gear 13 and an output pipe 4 rotate, causing a set of nozzles 5 to rotate and spray. Since each set of nozzles 5 is equipped with an electric control valve, the electric control valve controls when the liquid in the nozzle 5 is sprayed. When the nozzle 5 rotates to a position where the amendment is no longer needed, the electric control valve closes, reducing amendment waste and increasing the spraying range of the amendment, ensuring that the amendment is sprayed without dead angles or blind spots. Furthermore, through the intelligent control of the electric control valve, the operator can precisely adjust the spray volume and spraying time of each nozzle 5 according to actual needs, realizing a personalized spraying plan. This not only improves the efficiency of amendment use but also reduces the frequency of manual intervention, further reducing labor costs.

[0021] A circular rod 28 is fixedly connected to the top of the outer wall of the output pipe 4; a stirring rod 29 is rotatably connected to the bottom of the inner wall of the storage tank 15; a set of stirring plates 30 is fixedly connected to the outer wall of the stirring rod 29; sprockets 31 are fixedly connected to the outer walls of both the stirring rod 29 and the circular rod 28, and the pair of sprockets 31 are connected by a chain 32. When the output pipe 4 rotates, it drives the circular rod 28 to rotate, and the circular rod 28 drives the stirring rod 29 to rotate through the sprockets 31 and the chain 32, causing the stirring rod 29 to drive the stirring plates 30 to rotate, thus stirring the improver in the storage tank 15. During the continuous rotation of the stirring plate 30, sedimentation or stratification of the soil conditioner in the storage tank 15 can be effectively prevented, ensuring that the composition of the soil conditioner is uniform and consistent. The stirring force generated by the rotation of the stirring plate 30 ensures that the various components in the soil conditioner are fully mixed, avoiding the problem of excessively high or low local concentrations caused by prolonged stillness. This ensures that when the pump body 3 extracts the soil conditioner from the storage tank 15, the extracted soil conditioner has the same composition and concentration, thereby guaranteeing the stability and consistency of the spraying effect and improving the quality and efficiency of saline-alkali land improvement.

[0022] A double-sided rack 17 is fixedly connected to the top of the outer wall of the workbench 1 via a connecting plate 16; a set of nozzles 5 are all rotatably and sealed on the outer wall of the output pipe 4; a third gear 18 is fixedly connected to the outer wall of each set of nozzles 5; each set of third gears 18 meshes with the double-sided rack 17. When the nozzle 5 rotates with the output pipe 4, the third gear 18 on the nozzle 5 rotates accordingly. Because each set of third gears 18 meshes with the double-sided rack 17, when the nozzle 5 drives the third gear 18 to rotate, the double-sided rack 17 rotates, thus causing the nozzle 5 to rotate while revolving around the infusion pipe. This makes the droplets sprayed from the nozzle 5 no longer a fixed-pointing fan shape, but a dynamically rotating one. When countless such dynamic scattering cones are superimposed on a large circle formed by revolution, the tiny patches of land within the spraying area are repeatedly covered by droplets from different angles and time points, eliminating the microscopic blind spots that are difficult to avoid in traditional spraying. This achieves uniform coverage from macroscopic width to microscopic particles. Furthermore, the rotation of the nozzle 5 applies a tangential tearing force to the droplets just sprayed from the nozzle, breaking larger droplets into finer particles, i.e., secondary atomization. Finer droplets mean a larger specific surface area, which can be more evenly adsorbed onto the surface of soil particles or plant stems and leaves in saline-alkali soil. With the same amount of pesticide, the utilization rate of the amendment is significantly improved, and waste is reduced.

[0023] A set of auxiliary rods 33 is rotatably connected to the outer wall of the circular rod 28; a set of fan blades 34 is fixed to the outer wall of the auxiliary rods 33; a sixth gear 35 is fixed to the outer wall of each set of auxiliary rods 33; a sixth annular rack 36 is fixed to the top of the outer wall of the connecting plate 16 through a connecting rod; each set of sixth gears 35 meshes with the sixth annular rack 36. When the circular rod 28 rotates, it drives the set of auxiliary rods 33 and the sixth gears 35 thereon to rotate as well. Since each set of sixth gears 35 meshes with the sixth annular rack 36, the rotation of the sixth gears 35 causes the sixth annular rack 36 to rotate, thereby driving the auxiliary rods 33 to rotate, causing the fan blades 34 to rotate. The airflow generated by the rotation of the fan blades 34 forms a local airflow above the storage tank 15, which not only helps to accelerate the volatilization and dispersion of the modifier on the surface, but also promotes the uniform distribution of the modifier in the storage tank 15. Furthermore, the airflow generated by the fan blades 34 can cause the modifier to flow slightly, making the modifier diffuse over a wider range and distribute more evenly.

[0024] A set of rotating rods 19 is rotatably connected to the outer wall of the output pipe 4; a square block 20 is provided on the outer wall of the set of rotating rods 19; a set of striking rods 21 is fixedly connected to the outer wall of the square block 20, and multiple sets of striking rods 21 are respectively matched with a set of nozzles 5; a fourth gear 22 is fixedly connected to the outer wall of each set of rotating rods 19, and each set of fourth gears 22 meshes with a double-sided rack 17; a set of circular through slots 23 is opened on one side of the outer wall of the striking rod 21. When the output pipe 4 rotates, the output pipe 4 drives the rotating rods 19 and the fourth gears 22 to rotate. Since each set of fourth gears 22 meshes with the double-sided rack 17, the fourth gears 22 rotate through the double-sided rack 17, driving the rotating rods 19 to rotate, which in turn drives the square block 20 and the set of striking rods 21 to rotate. The sprayed amendment is dynamically impacted, and the resulting shockwaves tear large droplets into countless micron-sized ultrafine droplets. This achieves a triple-fragmentation effect of pressure atomization, centrifugal atomization, and mechanical impact atomization, making it easier to handle amendments with higher viscosity. The droplet size distribution is also more concentrated, increasing the surface area covered by the unit solution. Furthermore, through the circular channel 23, some of the amendment is sprayed out while some is impacted, forming a combination of droplets with different sizes. This better adapts to saline-alkali soils of varying textures and densities. The micron-sized ultrafine droplets penetrate deep into soil pores, improving the amendment's penetration. For looser soils, the combination of droplets with different sizes increases the surface area for the amendment, reducing loss.

[0025] The outer side wall of the rotating rod 19 is provided with a sliding groove 24; the inner side wall of the square block 20 is slidably connected to the inner side wall of the sliding groove 24; the outer side wall of the rotating rod 19 is rotatably connected to the reciprocating rod 25 through the square block 8, and the reciprocating rod 25 and the square block 20 are in a reciprocating connection relationship; a fifth gear 26 is fixedly connected to one end of the outer wall of the reciprocating rod 25; a set of fifth ring racks 27 are fixedly connected to the outer side wall of the output pipe 4 through a set of fixed rods; a set of fifth gears 26 meshes with a set of fifth ring racks 27 respectively.

[0026] Because the striking rod 21 is usually fixed at a specific position, its range of action is limited to a thin sheet-like area between the nozzle 5 and that point. Only droplets that happen to pass through this fixed cross section can be struck, while droplets at other distances are not mechanically interfered with at all.

[0027] The rotating rod 19 drives the square block 20 and a set of striking rods 21 to rotate, dynamically striking the sprayed modifier. Simultaneously, the rotating rod 19 drives the reciprocating rod 25 and its fifth gear 26 to rotate via the square block 8. Since the set of fifth gears 26 meshes with a set of fifth ring racks 27, the rotation of the fifth gears 26, through the rotation of the fifth ring racks 27, drives the reciprocating rod 25 to rotate. This rotation of the reciprocating rod 25 then moves the square block 20 and the striking rods 21. At this time, the square block 20 slides in the groove 24 on the rotating rod 19. The internal movement causes the striking rod 21 to rotate and strike simultaneously. Through the reciprocating motion of the striking rod 21, its striking range dynamically scans between the near and far ends of the nozzle 5. When the striking rod 21 moves to the near end, it strikes the largest droplets that have just left the nozzle 5 and are moving at the fastest speed. When it moves to the far end, it intervenes with the fine droplets that are about to fall and are about to stop. This ensures that droplets in every space along the entire path from the nozzle 5 outlet to the soil surface have the opportunity to be struck multiple times and from multiple angles, eliminating the striking blind spots that are difficult to avoid with a fixed striking rod 21.

[0028] Example 2: Please see Figure 7 and Figure 9As shown, a pair of vibrating rods 37 are rotatably connected to the outer wall of the storage tank 15 via a pair of square blocks 5; an eighth gear 38 is fixedly connected to the outer wall of both the pair of vibrating rods 37 and the agitator 29, and a set of eighth gears 38 mesh with each other; a set of vibrating balls 40 is fixedly connected to the outer wall of the vibrating rods 37 via a set of flexible rods 39; the vibrating balls 40 are matched with the storage tank 15, and when the agitator 29 rotates, it drives the pair of vibrating rods 37 to rotate through the set of eighth gears 38, thereby driving the two sets of flexible rods 39 and the vibrating balls 40 to rotate, causing the vibrating balls 40 to rotate. The vibration ball 40 continuously strikes the storage tank 15, causing it to vibrate slightly. This effectively prevents the modifier from adhering to and clumping on the inner wall of the storage tank 15, ensuring that the modifier flows smoothly out of the storage tank 15 and avoiding the impact of clogging or poor flow on the spraying effect. At the same time, the striking of the vibration ball 40 promotes the mixing inside the modifier, making the composition of the modifier more uniform and improving the spraying quality. The vibration also helps to reduce the amount of residual modifier in the storage tank 15, reducing waste and improving the efficiency of modifier use.

[0029] In use, the pump body 3 on the workbench 1 delivers the amendment from the storage tank 15 to the output pipe 4. When it is sprayed out through the nozzle 5, the motor 9 drives the rotating shaft 10 to rotate, which in turn drives the drive shaft 7 to rotate through the sprocket 11 and chain 12. This causes a pair of drive wheels 8 to rotate in the track 2, moving the workbench 1. At this time, a set of sliding support plates 6 are responsible for supporting the workbench 1 and cleaning impurities in the track 2. The nozzle 5 sprays the amendment while moving with the workbench 1, allowing the invention to continuously perform large-area operations, increasing the spraying range of saline-alkali land improvement, thus eliminating the need for manual labor and work interruption, reducing costs while increasing work efficiency, and making the amendment distribution more uniform.

[0030] Motor 9 synchronously drives the second bevel gear 14 to rotate via rotating shaft 10. The second bevel gear 14 then drives the first bevel gear 13 and output pipe 4 to rotate, causing a set of nozzles 5 to rotate and spray. Since each set of nozzles 5 is equipped with an electric control valve, the electric control valve controls when the liquid in the nozzle 5 is sprayed. When the nozzle 5 rotates to a position where the amendment is no longer needed, the electric control valve closes, reducing amendment waste and increasing the spraying range of the amendment. This ensures that the amendment is sprayed without dead angles or blind spots. Furthermore, through the intelligent control of the electric control valve, the operator can precisely adjust the spray volume and spraying time of each nozzle 5 according to actual needs, realizing a personalized spraying plan. This not only improves the efficiency of amendment use but also reduces the frequency of manual intervention, further reducing labor costs.

[0031] Because a set of third gears 18 mesh with the double-sided rack 17, when the nozzle 5 drives the third gear 18 to rotate, the double-sided rack 17 rotates, causing the nozzle 5 to rotate while revolving around the infusion tube. This makes the droplets sprayed from the nozzle 5 no longer a fixed-pointing fan, but a dynamically rotating scattering cone. When countless such dynamic scattering cones are superimposed on the large circumference formed by the revolution, the small patches of land in the spraying area will be repeatedly covered by droplets from different angles and time points, eliminating the microscopic blind spots that are difficult to avoid in traditional spraying. This achieves uniformity across the entire area from macroscopic width to microscopic particles. Furthermore, the rotation of the nozzle 5 will apply a tangential tearing force to the droplets just sprayed from the nozzle, breaking larger droplets into finer particles, i.e., secondary atomization. Finer droplets mean a larger specific surface area, which can be more evenly adsorbed onto the surface of soil particles or plant stems and leaves in saline-alkali land. With the same amount of pesticide, the utilization rate of the amendment is significantly improved, and waste is reduced.

[0032] The output pipe 4 drives the rotating rod 19 and the fourth gear 22 to rotate. Since all four gears 22 mesh with the double-sided rack 17, the rotation of the fourth gears 22 through the double-sided rack 17 drives the rotating rod 19 to rotate. The rotating rod 19 then drives the square block 20 and a set of impact rods 21 to rotate, dynamically impacting the sprayed modifier. The shock wave generated by the impact tears the large droplets into countless micron-sized ultrafine droplets, achieving a triple fragmentation effect of pressure atomization, centrifugal atomization, and mechanical impact atomization, thus facilitating the processing of more... The high-viscosity soil conditioner, with its more concentrated droplet size distribution, increases the surface area covered by the unit solution. Through the circular channel 23, some of the conditioner is sprayed out while some is impacted, forming a combination of droplets with different sizes. This allows for better adaptation to saline-alkali soils of varying textures and densities. The micron-sized ultrafine droplets penetrate deep into soil pores, enhancing the conditioner's penetration. For looser soils, the combination of droplets with different sizes increases the surface area of ​​the conditioner, reducing loss.

[0033] The rotating rod 19 drives the square block 20 and a set of striking rods 21 to rotate, dynamically striking the sprayed modifier. Simultaneously, the rotating rod 19 drives the reciprocating rod 25 and its fifth gear 26 to rotate via the square block 8. Since the set of fifth gears 26 meshes with a set of fifth ring racks 27, the rotation of the fifth gears 26, through the rotation of the fifth ring racks 27, drives the reciprocating rod 25 to rotate. This rotation of the reciprocating rod 25 then moves the square block 20 and the striking rods 21. At this time, the square block 20 slides in the groove 24 on the rotating rod 19. The internal movement causes the striking rod 21 to rotate and strike simultaneously. Through the reciprocating motion of the striking rod 21, its striking range dynamically scans between the near and far ends of the nozzle 5. When the striking rod 21 moves to the near end, it strikes the largest droplets that have just left the nozzle 5 and are moving at the fastest speed. When it moves to the far end, it intervenes with the fine droplets that are about to fall and are about to stop. This ensures that droplets in every space along the entire path from the nozzle 5 outlet to the soil surface have the opportunity to be struck multiple times and from multiple angles, eliminating the striking blind spots that are difficult to avoid with a fixed striking rod 21.

[0034] When the output pipe 4 rotates, it drives the circular rod 28 to rotate. The circular rod 28 drives the stirring rod 29 to rotate through the sprocket 21 and the chain 22. The stirring rod 29 drives the stirring plate 30 to rotate, stirring the amendment in the storage tank 15. During the continuous rotation of the stirring plate 30, it can effectively prevent the amendment from settling or stratifying in the storage tank 15, ensuring that the composition of the amendment is uniform. The stirring force generated by the rotation of the stirring plate 30 ensures that the various components in the amendment are fully mixed, avoiding the problem of local concentration being too high or too low due to long-term stillness. When the pump body 3 draws the amendment from the storage tank 15, the amendment drawn has the same composition and concentration, thus ensuring the stability and consistency of the spraying effect and improving the quality and efficiency of saline-alkali land improvement.

[0035] When the circular rod 28 rotates, it drives a set of auxiliary rods 33 and the sixth gear 35 on them to rotate as well. Since the set of sixth gears 35 are all meshed with the sixth ring rack 36, when the sixth gear 35 rotates, it drives the sixth ring rack 36 to rotate, thereby driving the auxiliary rods 33 to rotate, causing the fan blades 34 to rotate. The airflow generated by the rotation of the fan blades 34 forms a local airflow above the storage tank 15, which not only helps to accelerate the dissipation of volatile components on the surface of the modifier, but also promotes the uniform distribution of the modifier in the storage tank 15. In addition, the airflow generated by the fan blades 34 can drive the modifier to move slightly, making the modifier diffuse over a larger range and distribute more evenly.

[0036] When the stirring rod 29 rotates, it drives a pair of vibrating rods 37 to rotate through a set of eighth gears 38, which in turn drives two sets of flexible rods 39 and vibrating balls 40 to rotate. The vibrating balls 40 strike the inside of the storage tank 15. After being continuously struck by the vibrating balls 40, the storage tank 15 produces slight vibrations, which effectively prevents the amendment from adhering to and clumping on the inner wall of the storage tank 15, ensuring that the amendment flows smoothly out of the storage tank 15 and avoiding the impact of clogging or poor flow on the spraying effect. At the same time, the striking of the vibrating balls 40 promotes the mixing inside the amendment, making the composition of the amendment more uniform and improving the spraying quality. The vibration also helps to reduce the amount of residual amendment in the storage tank 15, reducing waste and improving the efficiency of amendment use.
