Description

Technical Field

[0001] This invention relates to grassland spraying technology, specifically to a mobile grassland spraying and irrigation vehicle. Background Technology

[0002] Grasslands, as vital ecosystems, not only provide habitats for numerous wild plants and animals but also play an irreplaceable and crucial role in soil and water conservation, climate regulation, and windbreak and sand fixation. Simultaneously, grasslands are a vital foundation for livestock development; high-quality grassland forage is the material guarantee for healthy livestock growth and the provision of high-quality livestock products. However, grasslands inevitably suffer from pests and diseases during their growth, which severely impact forage quality, reduce forage yield, and consequently affect grassland ecological stability and the sustainable development of livestock farming. Therefore, conducting scientific and rational pesticide spraying operations on grasslands is an important measure to ensure healthy grassland growth, maintain grassland ecological balance, and promote livestock development.

[0003] Currently, there are many types of grassland spraying equipment on the market, but most of them have some problems that urgently need to be solved. Regarding the mixing of pesticides and water, many traditional spraying devices use a simple stirring method, relying solely on a single-direction stirring paddle to mix the pesticide and water. This stirring method has obvious limitations. Due to the unidirectional stirring, localized mixing dead zones easily form during the mixing process, resulting in the pesticide and water not being fully and evenly mixed. In subsequent spraying, uneven spraying occurs. In some areas, the pasture may be damaged by excessively high pesticide concentrations, affecting its normal growth; while in other areas, the pesticide concentration may be too low to effectively control pests and diseases, thus reducing the control effect and failing to achieve the intended spraying purpose.

[0004] In summary, existing grassland spraying equipment has some shortcomings in pesticide mixing, failing to meet the needs of modern grassland ecological protection and livestock development. Therefore, developing a new type of grassland spraying equipment that can effectively solve the above problems is of significant practical importance. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile grassland spraying and irrigation vehicle to solve the problem in the prior art where the pesticide and water cannot be mixed sufficiently and evenly during the spraying process, resulting in uneven spraying. In some areas, the pasture may be damaged by the pesticide due to excessively high concentration, affecting its normal growth, while in other areas, the pasture may be unable to effectively control pests and diseases due to insufficient pesticide concentration, thereby reducing the control effect and failing to achieve the expected spraying purpose.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile grassland spraying and irrigation vehicle, comprising an irrigation vehicle body, a mixing water tank fixedly connected to the irrigation vehicle body, a mixing pipe rotatably connected to the mixing water tank, a plurality of stirring plates fixedly connected to the outer surface of the mixing pipe, and a driving mechanism drivingly connected to the outer surface of the mixing pipe, the driving mechanism being used to drive the mixing pipe to rotate;

[0007] The mixing pipe is equipped with an internal circulation mixing mechanism connected to the mixing tank. The internal circulation mixing mechanism is used to mix the medicine and water in the mixing tank. The bottom of the mixing tank is fixedly connected to a first water pump that is fixedly connected to the main body of the irrigation vehicle through a pipe. The output end of the first water pump is fixedly connected to a hose. One end of the hose is fixedly connected to a spray pipe that is fixedly connected to the main body of the irrigation vehicle. Multiple spray heads are fixedly connected to the outer surface of the spray pipe.

[0008] Furthermore, the driving mechanism includes a rotating driving component fixedly connected to the mixing tank, a driving shaft fixedly connected to the output end of the rotating driving component, a first gear fixedly sleeved on the outer surface of the driving shaft, a second gear fixedly sleeved on the outer surface of the first gear, and the internal circulation mixing mechanism is connected to the outer surface of the driving shaft for transmission.

[0009] Furthermore, the internal circulation mixing mechanism includes two inlet pipes rotatably connected to the mixing pipe, and multiple first outlets are provided on the inlet pipes. A stirring shaft is fixedly connected between the two inlet pipes, and multiple first stirring columns are fixedly connected to the outer surface of the stirring shaft. Multiple first stirring rods are fixedly connected to the outer surface of the first stirring columns. Multiple second outlets are provided in the middle of the mixing pipe. The outer surface of one of the inlet pipes is connected to the drive shaft via a transmission belt and a transmission wheel. A second water pump is fixedly connected to the bottom of the mixing tank via a pipe. A first connecting pipe is fixedly connected to the output end of the second water pump. Two second connecting pipes are fixedly connected to one end of the first connecting pipe, and a third connecting pipe rotatably connected to the inlet pipe is fixedly connected to one end of the second connecting pipe.

[0010] Furthermore, a plurality of second stirring columns are fixedly connected to the inner surface of the mixing tube, and a plurality of second stirring rods are fixedly connected to the outer surface of the second stirring columns.

[0011] Furthermore, a filter screen is fixedly connected to the inlet end of the first water pump.

[0012] Furthermore, a transmission plate is fixedly connected to the outer surface of the mixing tube, and a cleaning brush is fixedly connected to the outer surface of the transmission plate.

[0013] Furthermore, a connecting plate is fixedly connected to one side of the main body of the irrigation vehicle, a telescopic drive component is fixedly connected to the bottom of the connecting plate, an installation plate is fixedly connected to the output end of the telescopic drive component, and the bottom of the installation plate is fixedly connected to the spray pipe.

[0014] Furthermore, a water supply pipe is fixedly connected to the top of the mixing tank, and a sealing block is threaded onto the water supply pipe.

[0015] Compared with the prior art, the mobile grassland spraying and irrigation vehicle provided by the present invention has the following beneficial effects:

[0016] The rotating drive unit drives the mixing pipe to rotate, which in turn drives the stirring plate to initially stir the pesticide and water in the mixing tank. Then, a second water pump pumps the initially mixed pesticide solution into the inlet pipe, which then enters the mixing pipe. Simultaneously, the drive shaft rotates the inlet pipe, and the stirring shaft rotates accordingly, agitating the pesticide solution in the mixing pipe. Because the mixing pipe and the inlet pipe rotate in opposite directions, the first and second stirring rods exert opposing stirring forces, ensuring thorough mixing of the pesticide solution within the mixing pipe, with further mixing occurring at the center due to collision. This repeated cycle effectively prevents uneven mixing of the pesticide and water, ensuring uniform spraying. This design solves the problem of insufficient mixing in traditional spraying equipment, improves spraying quality, ensures that grassland pasture receives uniform pesticide spraying, promotes healthy pasture growth, and enhances grassland ecological quality.

[0017] The mixing tube drives the transmission plate and cleaning brush to rotate, cleaning the pesticide adhering to the inner surface of the mixing tank during spraying to prevent incomplete dissolution. After use, the inner wall can be thoroughly cleaned, making the process convenient and quick. On the other hand, the telescopic drive can move the mounting plate and spray pipe, allowing adjustment of the spray pipe height according to the different heights of the grass. When dealing with grasses of varying heights on grasslands, it can be adjusted to the appropriate spraying height, ensuring effective spraying of grasses of different heights and improving spraying efficiency. These functions make this equipment suitable for various grassland environments, reducing manual cleaning costs, increasing work efficiency, and providing a superior and convenient solution for grassland spraying and irrigation.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1 to 6 As shown, the present invention provides a mobile grassland spraying and irrigation vehicle, including an irrigation vehicle body 1, a mixing water tank 2 fixedly connected to the irrigation vehicle body 1, a mixing pipe 3 rotatably connected to the mixing water tank 2, a plurality of stirring plates 4 fixedly connected to the outer surface of the mixing pipe 3, and a driving mechanism drivingly connected to the outer surface of the mixing pipe 3, the driving mechanism being used to drive the mixing pipe 3 to rotate.

[0030] An internal circulation mixing mechanism is provided on the mixing pipe 3 and connected to the mixing tank 2. The internal circulation mixing mechanism is used to mix the medicine and water in the mixing tank 2. The bottom of the mixing tank 2 is fixedly connected to the first water pump 5, which is fixedly connected to the main body 1 of the irrigation vehicle, through a pipe. The output end of the first water pump 5 is fixedly connected to the hose 6. One end of the hose 6 is fixedly connected to the spray pipe 7, which is fixedly connected to the main body 1 of the irrigation vehicle. Multiple spray heads 8 are fixedly connected to the outer surface of the spray pipe 7. The top of the mixing tank 2 is fixedly connected to the water supply pipe, and a sealing block is threaded on the water supply pipe.

[0031] The drive mechanism includes a rotating drive component 11 fixedly connected to the mixing tank 2. The rotating drive component 11 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the rotating drive component 11 is fixedly connected to a drive shaft 12. A first gear 13 is fixedly sleeved on the outer surface of the drive shaft 12. A second gear 14, which is fixedly sleeved on the outer surface of the first gear 13, is meshed with the outer surface of the first gear 13. The internal circulation mixing mechanism is connected to the outer surface of the drive shaft 12 for transmission. The rotating drive component 11 drives the drive shaft 12 to rotate, and the drive shaft 12 drives the mixing pipe 3 to rotate through the first gear 13 and the second gear 14.

[0032] The internal circulation mixing mechanism includes two inlet pipes 21 rotatably connected to the mixing pipe 3, and multiple first outlets 22 are provided on the inlet pipes 21. An agitator shaft 23 is fixedly connected between the two inlet pipes 21, and multiple first agitator columns 24 are fixedly connected to the outer surface of the agitator shaft 23. Multiple first agitator rods 25 are fixedly connected to the outer surface of the first agitator columns 24. Multiple second outlets 26 are provided in the middle of the mixing pipe 3. The outer surface of one of the inlet pipes 21 is connected to the drive shaft 12 via a transmission belt and a transmission wheel. A second water pump 27 is fixedly connected to the bottom of the mixing tank 2 via a pipe. A first connecting pipe 28 is fixedly connected to the output end of the second water pump 27. Two second connecting pipes 29 are fixedly connected to one end of the first connecting pipe 28. A third connecting pipe 290, which is rotatably connected to the inlet pipe 21, is fixedly connected to one end of the second connecting pipe 29.

[0033] Multiple second stirring columns 31 are fixedly connected to the inner surface of the mixing tube 3, and multiple second stirring rods 32 are fixedly connected to the outer surface of the second stirring columns 31.

[0034] A filter screen is fixedly connected to the inlet end of the first water pump 5.

[0035] The required spraying agent and water are mixed in a certain ratio, and then the mixed water and agent are poured into the mixing tank 2 through the water supply pipe. The drive shaft 12 is then rotated by the drive component 11, and the drive shaft 12, through the first gear 13 and the second gear 14, drives the mixing pipe 3 to rotate. The mixing pipe 3 drives the stirring plate 4 to rotate, and the stirring plate 4 stirs and mixes the agent and water in the mixing tank 2, achieving a preliminary mixture. Then, the second water pump 27 operates, pumping the preliminarily mixed agent solution through the first connecting pipe 28 into two second connecting pipes 29. The second connecting pipe 29 introduces the mixed medicine solution into the water inlet pipes 21 at both ends of the mixing pipe 3. The water inlet pipes 21 then convey the mixed medicine solution out through the first outlet 22, allowing it to enter the mixing pipe 3. Simultaneously, the drive shaft 12 drives the water inlet pipe 21 to rotate via a transmission wheel and belt. The water inlet pipe 21 drives the stirring shaft 23 to rotate, which in turn drives multiple first stirring columns 24 to rotate. The first stirring columns 24 agitate and mix the medicine solution in the mixing pipe 3. Simultaneously, the drive shaft 12 drives the second gear 14 to rotate via the first gear 13. The second gear 14 then drives the mixing pipe 3 to rotate. At this time, through the transmission of gears... When the mixing tube 3 rotates in the opposite direction to the drive shaft 12, the drive shaft 12 drives the inlet pipe 21 to rotate in the same direction via the transmission wheel and transmission belt. This causes the mixing tube 3 to rotate in the opposite direction to the inlet pipe 21, which in turn causes the stirring shaft 23 to rotate in the opposite direction to the mixing tube 3. Consequently, the second stirring column 31 on the mixing tube 3 drives the second stirring rod 32 to rotate in the opposite direction to the first stirring rod 25. This allows the medicine flowing in the mixing tube 3 to be thoroughly mixed under the opposing stirring forces of the first stirring rod 25 and the second stirring rod 32. Simultaneously, the flowing medicine collides at the center of the mixing tube 3. At this point, the drug and water are further mixed under the action of the impact force, and then discharged through the second outlet 26 on the mixing pipe 3. Then, the mixed drug solution is pushed into the mixing pipe 3 again by the second water pump 27 for further mixing. This process is repeated to ensure that the sprayed drug and water are fully mixed, effectively preventing uneven mixing of the drug and water from causing uneven spraying in subsequent applications. Then, the second water pump 27 is started, and the second water pump 27 delivers the mixed drug solution through the pipe to the hose 6. The hose 6 then pushes the mixed drug solution into the spray pipe 7, and the spray pipe 7 sprays the drug out through the spray head 8, thus achieving the spraying of the drug.

[0036] Meanwhile, when it is necessary to irrigate the grassland, water is injected into the mixing tank 2, and then the first water pump 5 is started. The first water pump 5 works to pass water into the spray pipe 7, and then the spray pipe 7 sprays water out through the spray head 8 to irrigate the grassland plants.

[0037] Example 2

[0038] Based on Example 1, please refer to Figure 1 and Figure 5 As shown, a transmission plate 41 is fixedly connected to the outer surface of the mixing pipe 3, and a cleaning brush 42 is fixedly connected to the outer surface of the transmission plate 41.

[0039] A connecting plate 51 is fixedly connected to one side of the main body 1 of the irrigation vehicle. A telescopic drive component 52 is fixedly connected to the bottom of the connecting plate 51. The telescopic drive component 52 is an electric telescopic rod or an electric hydraulic rod. An installation plate 53 is fixedly connected to the output end of the telescopic drive component 52. The bottom of the installation plate 53 is fixedly connected to the spray pipe 7.

[0040] During the spraying process, the mixing pipe 3 drives the transmission plate 41 to rotate, which in turn drives the cleaning brush 42 to rotate. The cleaning brush 42 cleans the inner surface of the mixing tank 2, removing the pesticide adhering to the inner surface and preventing some pesticide from remaining undissolved in the water. After use, when it is necessary to clean the inside of the mixing tank 2, the transmission plate 41 drives the cleaning brush 42 to rotate, and the cleaning brush 42 thoroughly cleans the inner wall of the mixing tank 2, thus achieving portable cleaning of the mixing tank 2.

[0041] During the spraying process, when encountering grasses of different heights, the telescopic drive component 52 moves the mounting plate 53, which in turn moves the spray pipe 7, thereby adjusting the height of the spray pipe 7 to a suitable spraying height. This allows for effective spraying of grasses of different heights on the grassland, further improving the spraying effect on the grassland grasses.

[0042] Working principle: The required spraying medicine and water are mixed in a certain ratio, and then the mixed water and medicine are poured into the mixing tank 2 through the water supply pipe. Then, the drive shaft 12 is rotated by the drive component 11. The drive shaft 12 drives the mixing pipe 3 to rotate through the first gear 13 and the second gear 14. The mixing pipe 3 drives the stirring plate 4 to rotate. The stirring plate 4 stirs and mixes the medicine and water in the mixing tank 2, so that the medicine and water are initially mixed. Then, the second water pump 27 operates. The second water pump 27 introduces the initially mixed medicine solution into the two second connecting pipes 29 through the first connecting pipe 28. Subsequently, the mixed medicine solution is introduced into the water inlet pipes 21 at both ends of the mixing pipe 3 through the second connecting pipe 29. Then, the water inlet pipes 21 convey the mixed medicine solution out through the first outlet 22, allowing it to enter the mixing pipe 3. Simultaneously, the drive shaft 12 drives the water inlet pipe 21 to rotate via the transmission wheel and transmission belt. The water inlet pipe 21 drives the stirring shaft 23 to rotate, which in turn drives multiple first stirring columns 24 to rotate. The first stirring columns 24 agitate and mix the medicine solution in the mixing pipe 3. At the same time, because the drive shaft 12 drives the second gear 14 to rotate via the first gear 13, the second gear 14 drives the mixing pipe 3 to rotate. At this time, the gears... The transmission is such that the mixing tube 3 rotates in the opposite direction to the drive shaft 12, while the drive shaft 12 drives the inlet pipe 21 to rotate in the same direction via the transmission wheel and belt. This causes the mixing tube 3 to rotate in the opposite direction to the inlet pipe 21, which in turn causes the stirring shaft 23 to rotate in the opposite direction to the mixing tube 3. Consequently, the second stirring column 31 on the mixing tube 3 drives the second stirring rod 32 to rotate in the opposite direction to the first stirring rod 25. This allows the medicine flowing in the mixing tube 3 to be fully mixed under the opposing stirring forces of the first stirring rod 25 and the second stirring rod 32. At the same time, the flowing medicine collides at the center of the mixing tube 3. At this point, the drug and water are further mixed under the action of the impact force, and then discharged through the second outlet 26 on the mixing pipe 3. Then, the mixed drug solution is pushed into the mixing pipe 3 again by the second water pump 27 for further mixing. This process is repeated to ensure that the sprayed drug and water are fully mixed, effectively preventing uneven mixing of the drug and water from causing uneven spraying in subsequent applications. Then, the second water pump 27 is started, and the second water pump 27 delivers the mixed drug solution through the pipeline to the hose 6. The hose 6 then pushes the mixed drug solution into the spray pipe 7. Finally, the spray pipe 7 sprays the drug out through the spray head 8, thus achieving the spraying of the drug.

[0043] During the spraying process, the mixing pipe 3 drives the transmission plate 41 to rotate, which in turn drives the cleaning brush 42 to rotate. The cleaning brush 42 cleans the inner surface of the mixing tank 2, removing the pesticide adhering to the inner surface and preventing some pesticide from remaining undissolved in the water. After use, when it is necessary to clean the inside of the mixing tank 2, the transmission plate 41 drives the cleaning brush 42 to rotate, and the cleaning brush 42 thoroughly cleans the inner wall of the mixing tank 2, thus achieving portable cleaning of the mixing tank 2.

[0044] During the spraying process, when encountering grasses of different heights, the telescopic drive component 52 moves the mounting plate 53, which in turn moves the spray pipe 7, thereby adjusting the height of the spray pipe 7 to a suitable spraying height. This allows for effective spraying of grasses of different heights on the grassland, further improving the spraying effect on the grassland grasses.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
