Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This invention provides a sprayer that has the technical effect of automatically mixing and spraying pesticides.

[0030] refer to Figures 1 to 2 The present invention discloses a sprayer comprising a mobile vehicle body 1 and a liquid mixing device and a spraying device both mounted on the mobile vehicle body. The liquid mixing device includes a first housing 3, a stirring mechanism, and a driving mechanism. The first housing 3 has an inlet and an outlet. The stirring mechanism is located inside the first housing, and the driving mechanism is located outside the first housing 3 and is connected to the stirring mechanism. The spraying device includes a second housing 16, a nozzle 23, and a pressure applying mechanism. The second housing 16 has a cavity for storing liquid medicine and an inlet and an outlet. The outlet of the first housing 3 is connected to the inlet of the second housing 16, and the nozzle 23 is connected to the outlet. The pressure applying mechanism includes a pressure plate 15 slidably disposed in the cavity. The pressure plate 15 applies pressure to the liquid medicine in the cavity, driving the liquid medicine in the cavity to be sprayed out from the nozzle 23.

[0031] The system includes a feed pipe 28 at the inlet for easy material discharge, a stirring mechanism inside the first housing 3, and a drive mechanism for transmission. The medicine to be mixed enters the first housing 3 through the feed inlet. After the drive mechanism is started, the stirring mechanism can fully mix the medicine. The mixed medicine can enter the storage chamber in the second housing 16 through the outlet. Because the pressure plate 15 is slidably fitted inside the chamber, the pressure plate 15 can apply a squeezing force to the mixed medicine under the drive of the pressure applying mechanism, thereby driving the medicine from the outlet of the second housing 16 into the nozzle 23 and spraying it out from the nozzle 23, thus achieving the purpose of medicine spraying. Because the medicine mixing function and the medicine spraying function are integrated into the sprayer, the manual labor pressure can be effectively reduced, while improving work efficiency and achieving the technical effect of automated medicine mixing and spraying.

[0032] refer to Figure 2 and Figure 3 In this embodiment, the stirring mechanism includes a rotating shaft 5 and stirring blades 6 fixedly connected to the rotating shaft 5. The first housing 3 is a hollow cylindrical structure and is mounted on the vehicle body 1 through a support base 2. The rotating shaft 5 and the first housing 3 are coaxially arranged. The stirring blades 6 are arranged radially along the rotating shaft 5 and are distributed in multiple sets along the axial direction of the rotating shaft 5. The driving mechanism is located at the top of the first housing 3. The driving mechanism includes a driving motor 4, and the output end of the driving motor 4 is connected to the rotating shaft 5. The rotating shaft 5 is axially arranged in the first housing 3, which has a cylindrical structure. The stirring blades 6 are arranged along the axial direction of the rotating shaft 5, which can maximize the stirring effect of the stirring blades 6, so that the drug can be fully mixed in the first housing 3. This avoids the technical problem that different areas may be covered with different degrees of drug solution due to insufficient drug mixing, resulting in some areas receiving excessive drug solution while other areas receive insufficient drug solution, thereby affecting the treatment effect or causing unnecessary waste.

[0033] Furthermore, the drive mechanism also includes a cooperating active bevel gear 7 and a driven bevel gear 8, with the active bevel gear 7 connected to the output end of the drive motor 4; the pressure mechanism also includes an extension rod 15 that drives the pressure plate 15 to reciprocate up and down in the cavity, and an eccentric wheel mechanism that drives the extension rod 14 to reciprocate up and down; the eccentric wheel mechanism includes an eccentric wheel 10, a transmission rod 9, and a connecting rod 12, with one end of the transmission rod 9 fixedly connected to the driven bevel gear 8 and the other end of the transmission rod 9 fixedly connected to the eccentric wheel 10, and the drive motor 4 driving the eccentric wheel 10 to rotate through the active bevel gear 7, the driven bevel gear 8, and the transmission rod 9; one end of the connecting rod 12 is eccentrically hinged to the eccentric wheel 10 through a fixed rod 11, and the other end of the connecting rod 12 is hinged to the extension rod 14 through a connecting shaft 13; by setting up the gear pair mechanism, a single drive motor 4 can synchronously drive the stirring blade 6 and the pressure mechanism to operate, enabling synchronous drug mixing and liquid spraying operations, maximizing the continuity of operations and reducing the difficulty of operations.

[0034] refer to Figure 4 In this embodiment, a flexible hose 19 for guiding the liquid medicine is installed between the nozzle 23 and the outlet. A sealing connector 18 is installed at one end of the hose 19 connected to the outlet. A support rod 17 for supporting the nozzle 23 is also provided on the vehicle body 1. Two support arms protrude upwards from the top of the support rod 17, and mounting holes are provided at opposite positions of the two support arms. The nozzle is hinged between the two mounting holes via a connecting rod 21. A rotating buckle 22 is also installed on the outside of the connecting rod 21, which can adjust the rotation angle of the connecting rod 21, thereby adjusting the orientation of the nozzle 23. Under the action of the pressurizing mechanism, the liquid medicine enters the nozzle 23 through the hose 19 and is sprayed outwards. During spraying operations… The orientation of the nozzle 23 can be adjusted by adjusting the rotating buckle 22 to meet the spraying height requirements of different plants. As a further optimization, multiple sets of nozzles 23 can be provided in this embodiment to improve the spraying angle and further improve work efficiency. As a further optimization, in order to facilitate the replacement of nozzles 23, a rotating block 20 is hinged between the two support arms by a connecting rod 21. The rotating block 20 has a through mounting hole, through which the nozzle 23 is fixed. When it is necessary to replace the nozzle 23, simply remove the nozzle 23 from the rotating block 20 and disconnect it from the hose 19, and then reinstall a new nozzle 23.

[0035] refer to Figure 5 In this embodiment, the height of the feed inlet on the first box 3 is higher than the height of the liquid outlet, and the height of the liquid outlet is higher than the height of the drug inlet. The heights of both the drug inlet and the drug outlet are lower than the height of the pressure plate 15 at the lower limit position in the cavity. At the same time, a conveying pipe 29 is installed between the liquid outlet of the first box 3 and the drug inlet of the second box 16. A switch valve and a check valve are sequentially arranged on the conveying pipe 29 along the direction from the liquid outlet to the drug inlet. The on / off valve controls the opening and closing of the delivery pipe 29, and the one-way valve controls the flow direction of the liquid medicine in the delivery pipe 29. During the operation, if the liquid medicine is not fully mixed, the on / off valve can be closed to extend the mixing time of the liquid medicine in the first chamber 3, thereby achieving the requirement of fully mixing the liquid medicine. After the liquid medicine is fully mixed, the on / off valve is opened. Because the height of the liquid outlet is higher than the height of the liquid inlet, the liquid medicine in the first chamber 3 can passively enter the storage chamber of the second chamber 16 during the rising of the pressure plate 15. During the falling of the pressure plate 15, the liquid medicine in the chamber is squeezed. Under the action of the one-way valve, the liquid medicine enters the nozzle 23 through the liquid outlet and is sprayed out. That is, when the pressure plate 15 moves up, the chamber performs a replenishment action. When the pressure plate 15 moves down, the liquid medicine in the chamber is sprayed out by the nozzle 23, thus forming an intermittent supply and spraying process of liquid medicine.

[0036] refer to Figure 2In this embodiment, the vehicle body 1 is also provided with a fixing plate 27 for supporting the transmission rod 9 between the first box 3 and the second box 16. The fixing plate 27 has a support hole for supporting the transmission rod 9. The transmission rod 9 is sleeved in the support hole, and a bearing is installed between the outer wall of the transmission rod 9 and the inner wall of the support hole, thereby providing support for the transmission rod 9.

[0037] In this embodiment, the feed inlet of the first box 3 is provided with a removable sealing cover. When it is not necessary to supply medicine to the first box 3, the feed inlet can be sealed by the sealing cover, thereby avoiding the overflow of medicine during the mixing process.

[0038] In this embodiment, the bottom of the vehicle body is also equipped with a walking wheel 26 and a walking wheel drive system. The walking wheel 26 is rotatably connected to the connecting rod 25 and drives the vehicle body 1 to move through the walking wheel drive system. The vehicle body 1 is also equipped with a battery 24 and a control unit. The control unit is electrically connected to the battery 24, the drive motor 4 and the walking wheel drive system respectively.
