Description

Technical Field

[0001] This utility model relates to the field of fruit tree planting technology, and in particular to a portable spraying device for mandarin oranges. Background Technology

[0002] Fruit trees are susceptible to a wide variety of pests and diseases, which occur frequently throughout the year. If not controlled in time, they can cause serious losses. Regularly spraying pesticides on fruit trees is a relatively common and effective means of pest and disease control. When spraying pesticides on fruit trees, it is usually necessary to use a sprayer to spray the fruit trees in order to prevent pests and diseases.

[0003] A sprayer disclosed in Chinese Patent Publication No. CN220803885U features a manual pump body positioned in the middle of the casing, ensuring even weight distribution on both shoulders when the user carries the casing. The connection point between the joystick and connecting rod is also located in the middle of the casing, maintaining even weight distribution on both sides when the user operates the joystick, significantly improving the user experience. However, according to related technologies and existing techniques, this sprayer requires mixing the medicine and water together in the tank before shaking to mix them. This method is inconvenient, and the mixed medicine tends to settle during spraying, affecting the uniformity and effectiveness of subsequent spraying. Furthermore, when cleaning after spraying, the small opening of the tank necessitates adding cleaning agent and water together and shaking to clean the inside. This shaking method is inconvenient and doesn't allow the cleaning agent to fully take effect, impacting the cleaning result. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a portable mandarin orange spraying device.

[0005] The objective of this utility model is achieved through the following technical solution: a portable mandarin orange spraying device, comprising a medicine box, a piston-type air pump installed on the top of the medicine box, a drive assembly for controlling the operation of the piston-type air pump provided at the bottom of the medicine box, a stirring assembly for rotating and stirring the medicine liquid installed inside the medicine box, a transmission assembly for controlling the rotation of the stirring assembly provided on one side of the stirring assembly, a linkage assembly for providing power to the transmission assembly through the movement of the piston-type air pump at one end of the transmission assembly, an infusion tube fixedly provided at the output end of the piston-type air pump, and a spray gun fixedly provided at the end of the infusion tube away from the piston-type air pump.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 6As shown, a portable mandarin orange spraying device includes a medicine box 1. A piston-type air pump 3 is installed on the top of the medicine box 1, and a drive assembly 6 for controlling the operation of the piston-type air pump 3 is provided at the bottom of the medicine box 1. A stirring assembly 9 for rotating and stirring the medicine solution is installed inside the medicine box 1. A transmission assembly 8 for controlling the rotation of the stirring assembly 9 is provided on one side of the stirring assembly 9. A linkage assembly 7 for providing power to the transmission assembly 8 through the movement of the piston-type air pump 3 is provided at one end of the transmission assembly 8. An infusion tube 4 is fixedly provided at the output end of the piston-type air pump 3. A spray gun 5 is fixedly provided at the end of the infusion tube 4 away from the piston-type air pump 3. A shoulder strap 2 is fixedly provided on one side of the medicine box 1. A protective cover 10 is fixedly provided at the position of the medicine box 1 corresponding to the linkage assembly 7. In use, after adding the medicine and water into the medicine box 1, the medicine box 1 is carried on the back with the shoulder strap 2, and then the spray gun 5 is held in one hand and the other hand is held in the other hand. The drive assembly 6 is controlled to aim the spray gun 5 at the citrus tree. Then, the piston of the piston-type air pump 3 is controlled to move up and down through the drive assembly 6, which delivers the liquid medicine in the medicine tank 1 to the spray gun 5 through the piston-type air pump 3 and the infusion pipe 4. The liquid medicine is then sprayed out from the spray gun 5 to spray the citrus tree. During this process, the linkage assembly 7 moves synchronously with the piston of the piston-type air pump 3, and the stirring assembly 9 is controlled by the transmission assembly 8 to stir the liquid medicine in the medicine tank 1 to mix it evenly. When no preparation is needed, the medicine tank 1 is shaken to mix the liquid medicine. At the same time, the liquid medicine is stirred in real time during spraying to avoid precipitation of the medicine, which would cause uneven spraying and affect the spraying effect. In addition, during the subsequent cleaning, the cleaning agent and water are stirred to make the water continuously impact the inner wall of the medicine tank 1 to clean the inner wall of the medicine tank 1. At the same time, the cleaning agent and water are mixed evenly to make it more effective and improve the cleaning effect.

[0025] like Figure 1 and Figure 6 As shown, the drive assembly 6 includes a rocker arm 61 with one end hinged to the bottom of the medicine tank 1. A push rod 62 is installed between the rocker arm 61 and the piston-type air pump 3. The push rod 62 is C-shaped and its two ends are rotatably connected to the rocker arm 61 and the piston-type air pump 3, respectively. By rocking the rocker arm 61 up and down, it pushes the piston of the piston-type air pump 3 up and down through the push rod 62, so that the liquid medicine in the medicine tank 1 is sent to the spray gun 5 through the piston-type air pump 3 and the infusion pipe 4 in sequence, and sprayed out from the spray gun 5 to spray the citrus trees.

[0026] like Figures 1 to 6As shown, the stirring assembly 9 includes a stirring shaft 91 rotatably mounted at the center of the medicine tank 1. The lower end of the stirring shaft 91 extends into the inside of the medicine tank 1, and multiple stirring blades 92 are fixedly arranged along the axial direction. A worm gear 93 is fixedly arranged at the upper end of the stirring shaft 91, and a cavity for accommodating the worm gear 93 is opened at the top of the medicine tank 1. During the spraying process, the linkage assembly 7 moves synchronously with the piston of the piston-type air pump 3, thereby controlling the worm gear 93 to drive the stirring shaft 91 and stirring blades 92 to rotate through the transmission assembly 8, stirring the medicine liquid in the medicine tank 1 and mixing it evenly. When no preparation is needed, the medicine tank 1 is shaken to mix. At the same time, the medicine liquid is stirred in real time during spraying to avoid precipitation of the medicine, which would cause uneven spraying and affect the spraying effect. In addition, during subsequent cleaning, the stirring blades 92 can agitate the cleaning agent and water, causing the water to continuously impact the inner wall of the medicine tank 1 to clean it, while mixing the cleaning agent and water evenly to make it more effective and improve the cleaning effect.

[0027] like Figure 3 and Figure 4 As shown, the transmission assembly 8 includes multiple bearing seats 81 fixed to the top of the medicine box 1. A worm 82 that meshes with a worm wheel 93 is rotatably mounted between the multiple bearing seats 81. A gear 83 is fixedly provided at one end of the worm 82 near the piston-type air pump 3. The linkage assembly 7 drives the worm 82 to rotate under the support of the bearing seats 81 through the gear 83, so that the worm 82 meshes with the worm wheel 93 to rotate.

[0028] like Figure 1 and Figure 4 As shown, the linkage assembly 7 includes a synchronization plate 71 fixed to the top of the piston air pump 3. A fixing plate 72 is fixedly provided at the position corresponding to the gear 83 on the synchronization plate 71. A rack 73 that meshes with the gear 83 is fixedly provided on the fixing plate 72. Both the fixing plate 72 and the rack 73 penetrate the top of the protective cover 10. During the spraying of the citrus tree, the piston of the piston air pump 3 drives the rack 73 on the fixing plate 72 to move up and down synchronously through the synchronization plate 71. The rack 73 meshes with the gear 83 and drives the worm 82 to rotate under the support of the bearing 81, so that the worm 82 meshes with the worm wheel 93 to rotate.

[0029] The work process is as follows:

[0030] S1: As Figure 1 As shown, when using it, add the medicine and water together into the medicine box 1, and then carry the medicine box 1 on your back with the shoulder strap 2.

[0031] S2: As Figure 1 As shown, hold the spray gun 5 with one hand and the end of the joystick 61 with the other, and aim the spray gun 5 at the citrus tree;

[0032] S3: As Figure 3 and Figure 6As shown, the rocker arm 61 is then rocked up and down, causing it to push the piston of the piston-type air pump 3 to move up and down through the push rod 62. The liquid medicine in the medicine tank 1 is then sent to the spray gun 5 through the piston-type air pump 3 and the infusion pipe 4, and sprayed out from the spray gun 5 to spray the citrus tree.

[0033] S4: As Figure 3 and Figure 6 As shown, during this process, the piston of the piston-type air pump 3 drives the rack 73 on the fixed plate 72 to move up and down synchronously through the synchronizing plate 71.

[0034] S5: As Figures 3 to 5 As shown, the rack 73 meshes with the gear 83 and drives the worm 82 to rotate under the support of the bearing 81. The worm 82 meshes with the worm wheel 93, which drives the stirring shaft 91 and the stirring blade 92 to rotate and stir the liquid medicine in the medicine tank 1, so that it is mixed evenly. When no preparation is needed, the medicine tank 1 is shaken to mix. At the same time, the liquid medicine is stirred in real time during spraying to avoid precipitation of the medicine and uneven spraying.

[0035] S6: As Figure 5 As shown, in addition, during subsequent cleaning, the stirring blade 92 can agitate the cleaning agent and water, causing the water to continuously impact the inner wall of the medicine tank 1 to clean it, while mixing the cleaning agent and water evenly to make it more effective and improve the cleaning effect.

[0036] The piston-type air pump 3 and the spray gun 5 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
