[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figures 1 to 3 , the utility model provides a technical solution:
[0027] A pesticide spraying device for rice plant protection comprises a box body 1, a shoulder strap 11 is fixedly mounted on the rear end of the box body 1, a water injection bucket 12 is fixedly mounted on the top of the box body 1, a liquid storage chamber 2 and a liquid supply chamber 3 are respectively provided inside the box body 1 from top to bottom, a swing chamber 31 is provided on the left and right sides of the liquid supply chamber 3 inside the box body 1, a mounting groove 32 is provided on the front and rear end inner walls of the swing chamber 31, a group of spraying components 4 are installed inside the two groups of swing chambers 31, the spraying components 4 include a spray pipe 41 movably mounted inside the swing chamber 31, a spray head 42 is fixedly mounted on the bottom of the side of the spray pipe 41 away from the swing chamber 31, mounting columns 43 are fixedly mounted on the front and rear end positions of the spray pipe 41 on one side inside the swing chamber 31, and a first spring 44 is fixedly mounted on the upper and lower ends of the spray pipe 41 on one side inside the swing chamber 31;
[0028] The spray pipe 41 is movably installed in the swing chamber 31 through the mounting column 43 and the mounting slot 32. The spray pipe 41 can swing up and down through the mounting column 43 and the mounting slot 32. The first springs 44 installed at the upper and lower ends of the spray pipe 41 are both located in the swing chamber 31. The other sides of the two groups of the first springs 44 are against the inner walls of the upper and lower ends of the swing chamber 31. A micro water pump 33 is fixedly installed inside the liquid supply chamber 3. A water pumping pipe 34 is fixedly installed on the top of the micro water pump 33. The tube 34 passes through the partition between the liquid supply chamber 3 and the liquid storage chamber 2 and extends into the liquid storage chamber 2. A water supply pipe 35 is fixedly installed at the bottom of the micro water pump 33. The water supply pipe 35 is a Y-shaped water pipe. The water supply pipe 35 is fixedly connected to two groups of spray pipes 41 respectively. A water level window 14 is inlaid on the upper front end of the box body 1. The water level window 14 faces the liquid storage chamber 2 opened in the box body 1. A cover plate 15 is movably installed on the bottom front end of the box body 1. The cover plate 15 faces the liquid supply chamber 3 opened in the box body 1.
[0029] By adopting the above technical solution, when in use, first open the closing cover 13, and inject clean water and medicine into the liquid storage chamber 2 through the water injection bucket 12. When injecting clean water and medicine into the liquid storage chamber 2, the water level in the liquid storage chamber 2 can be observed through the water level window 14. Finally, close the closing cover 13, and carry the box body 1 through the shoulder strap 11. When the pesticide sprayer is in the rice field, turn on the micro water pump 33 in the liquid supply chamber 3. When working, the micro water pump 33 extracts the pesticide in the liquid storage chamber 2 through the water pumping pipe 34, and then transports it to the spraying pipes 41 on the left and right sides through the water supply pipe 35. Finally, the pesticide is sprayed downwards through the spray head 42. Through the above structural design, the device does not need to hold the spraying pipe 41 for a long time to spray pesticides when in use. The spraying pipe 41 is designed in the swing chamber 31. When spraying pesticides, turn on the micro water pump 33. The pesticide sprayer only needs to walk in the rice field to complete the spraying operation, thereby In order to reduce the working intensity of the pesticide spraying operation, the spray pipe 41 is installed in the swing chamber 31 through the cooperation of the spray pipe 41 and the mounting groove 32, so that the spray pipe 41 can be movable. When the pesticide sprayer walks in the rice field, his body will inevitably shake, which will cause the box 1 carried behind him to shake up and down. The spray pipe 41 is movably installed in the swing chamber 31. When the box 1 shakes with the shaking caused by the walking of the pesticide sprayer, the spray pipe 41 naturally shakes up and down. When the spray pipe 41 shakes, it will drive the spray head 42 installed at one end thereof to shake accordingly, thereby effectively increasing the spraying area of the spray head 42. A cover plate 15 is also installed on the front surface of the box 1. The cover plate 15 is installed by screws, and the cover plate 15 is opposite to the micro water pump 33 inside the liquid supply chamber 3. When the micro water pump 33 fails, the arrangement of the cover plate 15 can facilitate its maintenance.
[0030] The spray pipe 41 is located in the swing chamber 31. The upper and lower ends of one side are further provided with a first spring 44. When the spray pipe 41 is shaking, if the spray pipe 41 moves downward, the first spring 44 at the lower end is compressed, and the first spring 44 at the upper end is stretched. When the first spring 44 at the lower end is compressed to the limit, the spray pipe 41 moves upward accordingly. When the spray pipe 41 moves upward, the pressure of the compressed first spring 44 at the lower end is released to push the spray pipe 41 upward, while the first spring 44 at the upper end is in a compressed state, thereby repeating the above process. The above process causes the spray pipe 41 to shake continuously, increasing the amplitude of the shaking of the spray pipe 41, thereby further increasing the spraying range of the spray head 42, and the spray pipe 41 can also be guaranteed by the first spring 44. Even if the shaking amplitude of the pesticide sprayer is small when walking, the first spring 44 can ensure that the spray pipe 41 keeps shaking, the spraying area of the spray pipe 41 is improved, and the number of times the pesticide sprayer walks in the rice field will also be reduced, thereby further reducing the work intensity of the pesticide sprayer.
[0031] Specifically, such as Figures 3 and 4As shown, a mixing component 5 is provided inside the liquid storage chamber 2, and the mixing component 5 includes a column 51 fixedly installed inside the liquid storage chamber 2, and a gravity ball 53 is movably installed on the surface of the column 51, and a second spring 52 is sleeved on the surface of the column 51 below the gravity ball 53. A slide groove 56 is provided inside the gravity ball 53, and a swing groove 54 is provided on the surface of the gravity ball 53, and the number of swing grooves 54 is annular. The six groups of swing grooves 54 are all movably installed with swing plates 55. The structure of the swing plates 55 located in the swing grooves 54 is cylindrical and can swing up and down, and the structure of the swing plates 55 extending from the swing grooves 54 is in the shape of a paddle blade. The mixing component 5 is provided in two groups with the same structure. The two groups of mixing components 5 are respectively arranged on the left and right sides of the liquid storage chamber 2. The liquid storage chamber 2 is communicated with the water injection bucket 12 installed on the top of the box body 1, and a closing cover 13 is movably installed inside the water injection bucket 12.
[0032] By adopting the above technical solution, a column 51 is installed inside the liquid storage chamber 2, and a gravity ball 53 is movably installed on the surface of the column 51, and a second spring 52 is also sleeved on the surface of the column 51 below the gravity ball 53. When the pesticide sprayer walks in the rice field, the shaking of the box body 1 will also cause the liquid in the liquid storage chamber 2 to shake, and the shaking of the liquid in the liquid storage chamber 2 will cause the gravity ball 53 to move up and down slightly in the liquid storage chamber 2. When the gravity ball 53 moves up and down, the swing plate 55 on its surface will also shake. When the ball 53 rises along the column 51, the swing plate 55 will be in a downward tilted state. When the gravity ball 53 falls along the column 51, the swing plate 55 will be in an upward tilted state. This is repeated. Through the up and down shaking of the swing plate 55, the liquid in the liquid storage chamber 2 can be made to be unstable to a certain extent, and the liquid in the liquid storage chamber 2 will not remain static in the liquid storage chamber 2, thereby ensuring the mixing effect between the liquid in the liquid storage chamber 2 and the pesticide. The second spring 52 can also play a certain assisting effect on the gravity ball 53, so that the gravity ball 53 can maintain a state of moving up and down.
[0033] Working principle: When in use, first remove the closing cover 13 in the water injection bucket 12, then inject liquid and pesticide into the liquid storage chamber 2, and then carry the box body 1 on the back through the shoulder strap 11. When spraying pesticides, turn on the micro water pump 33, and the micro water pump 33 extracts the pesticide in the liquid storage chamber 2 through the water pumping pipe 34, and then supplies it to the spraying pipes 41 on both sides through the water supply pipe 35. Finally, the pesticide is sprayed out through the spraying pipes 41 and the spraying heads 42 on both sides, and pesticides are sprayed on the rice on both sides at the same time. The shaking caused by the pesticide sprayer when walking will cause the spraying pipe 41 to shake. When shaking, the spraying pipe 41 will trigger the first spring 44. The first spring 44 can ensure the ability of the spraying pipe 41 to shake continuously, and the spraying pipe 41 can increase the spraying efficiency when shaking. The spraying range of the sprinkler head 42, and the shaking of the box body 1 as the pesticide sprayer walks will also cause the gravity ball 53 in the liquid storage chamber 2 to move up and down along the column 51. The gravity ball 53 is immersed in the liquid in the liquid storage chamber 2, and its shaking amplitude with the liquid is small. When the gravity ball 53 moves downward to compress the second spring 52 at the bottom, the ability of the second spring 52 to be released after being compressed can make the gravity ball 53 move upward along the column 51, thereby ensuring that the gravity ball 53 can still shake up and down when soaked in liquid. Although the shaking amplitude of the gravity ball 53 is small, the gravity ball 53 can still make the liquid in the liquid storage chamber 2 unable to remain static through the swing plate 55, thereby avoiding the liquid from standing and the precipitation of pesticides.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
