Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a spraying device for a plant protection machine, including a base 1, a water tank 2 and a water pump 3. The top of the base 1 is connected to the water tank 2, and the bottom end of the outer wall of the water tank 2 is connected to the water pump 3 through an installation cavity. Moreover, the output end of the water pump 3 is butted with a liquid delivery pipe 4. One side of the liquid delivery pipe 4 away from the water pump 3 is connected to a nozzle 5. And an auxiliary mechanism 6 is arranged above the base 1. And the auxiliary mechanism 6 includes a medicine adding port 601, a guide plate 602, a fixed column 603, a fixed cylinder 604, a medicine adding cylinder 605, a threaded column 606, a threaded rod 607, a limiting rod 608, a limiting column 609, a servo motor 610, a driving gear 611, a driven gear 612, a main stirring rod 613 and a driven stirring rod 614. A medicine adding port 601 is opened in the middle of the top end of the water tank 2. And one side of the top end of the water tank 2 close to the medicine adding port 601 is connected to a guide plate 602. The middle of the top end of the guide plate 602 is welded with a fixed cylinder 604. And a medicine adding cylinder 605 is slidably connected inside the fixed cylinder 604. A servo motor 610 is installed in the middle of the outer wall of the water tank 2. And the output end of the servo motor 610 is butted with a driving gear 611; Both sides of the top end of the guide plate 602 are slidably connected with fixed columns 603. And one side of the outer wall of the fixed column 603 is connected to the base 1 through a support seat; The top end of the guide plate 602 is connected with a threaded column 606 through a bearing seat. And a threaded rod 607 is threadedly connected inside the threaded column 606; The top end of the medicine adding cylinder 605 is welded with a limiting rod 608. And a limiting column 609 is slidably connected to the outer wall of the limiting rod 608; The outer wall of the driving gear 611 is meshed with a driven gear 612. And a main stirring rod 613 is butted inside the driving gear 611; A driven stirring rod 614 is butted inside the driven gear 612. And one side of the driven stirring rod 614 away from the driven gear 612 is connected to the inner wall of the water tank 2 through a bearing seat; The top end of the threaded rod 607 is welded to the medicine adding cylinder 605. The bottom end of the limiting column 609 is welded to the guide plate 602. The guide plate 602 is slidably connected with the base 1. The main stirring rod 613 is rotatably connected with the water tank 2. A storage cavity is opened on one side of the water tank 2 close to the servo motor 610.

[0022] During specific implementation, when spraying medicine on crops through the spraying device in the plant protection machine and it is necessary to control the amount of medicine added to prevent excessive addition of medicine during medicine addition, since the threaded column 606 and the threaded rod 607 are threadedly connected, first manually rotate the threaded column 606 to make the threaded rod 607 move upward. Then, the upward movement of the threaded rod 607 drives the medicine adding cylinder 605 to move upward. At this time, the total length of the medicine adding cylinder 605 and the fixed cylinder 604 changes. And because the medicine adding cylinder 605 is connected to the limiting rod 608, at this time, the limiting rod 608 rotates along the limiting column 609, thereby guiding the movement of the medicine adding cylinder 605 and making the medicine adding cylinder 605 move smoothly;

[0023] Until the medicine adding cylinder 605 is lifted to the specified height, at this time, the total capacity of the medicine adding cylinder 605 and the fixed cylinder 604 is the amount of medicine added this time. Then, the guide plate 602 is pushed to move towards the medicine adding port 601. Since the fixed column 603 and the guide plate 602 are slidably connected, the movement of the guide plate 602 is guided by the fixed column 603 at this time until the center of the fixed cylinder 604 coincides with the center of the medicine adding port 601. At this time, the medicine inside the medicine adding cylinder 605 and the fixed cylinder 604 is introduced into the water tank 2 through the medicine adding port 601, thus preventing excessive medicine addition during medicine adding, which may cause the drug concentration in the liquid medicine to exceed the standard and affect the spraying work. Moreover, by adjusting the height of the medicine adding cylinder 605, it is convenient for the staff to adjust the amount of medicine added this time;

[0024] In order to quickly mix the medicine and the water flow, and prevent relatively large medicine residues from affecting the mixing work, the servo motor 610 is started first. Since the output end of the servo motor 610 is connected to the driving gear 611, when the servo motor 610 is started, it drives the driving gear 611 to rotate. And since the driving gear 611 and the driven gear 612 are meshed, the forward rotation of the driving gear 611 drives the driven gear 612 to rotate. And since the driving gear 611 is connected to the active stirring rod 613 and the driven gear 612 is connected to the driven stirring rod 614, at this time, the driving gear 611 drives the active stirring rod 613 to rotate forward, and the driven gear 612 drives the driven stirring rod 614 to rotate in the reverse direction;

[0025] Furthermore, a relative stirring mechanism is formed in the water tank 2, so that the water flow and the medicine in the water tank 2 are quickly mixed. And since the medicine adding port 601 is located above the junction of the active stirring rod 613 and the driven stirring rod 614, when the medicine enters the water tank 2, it is crushed by the relatively rotating active stirring rod 613 and the driven stirring rod 614, thus preventing relatively large medicine residues from affecting the mixing of the liquid medicine. Therefore, when the spraying device of the plant protection machinery is used, it plays a role in facilitating quantitative medicine addition and quickly mixing the liquid medicine.

[0026] In summary, when the spray device of the plant protection machine is in use, first move the water tank 2 to the designated location through the base 1, then introduce the drug into the interior of the water tank 2 through the medicine adding port 601. After that, make the dregs and water flow mix to form the liquid medicine through the stirring shaft. Then start the water pump 3 to export the liquid medicine from the water tank 2. After that, guide the liquid medicine to the nozzle 5 through the liquid delivery pipeline 4. Finally, spray the liquid medicine in a mist form onto the crops through the nozzle 5. This is the prior art and will not be elaborated here. The auxiliary mechanism 6 is used to prevent excessive addition of drugs during medicine addition, thereby preventing the drug concentration in the liquid medicine from exceeding the standard and affecting the spraying work. Moreover, a relative stirring mechanism is formed in the water tank 2, thereby quickly mixing the water flow and the drug, and the drug is crushed by the relatively rotating active stirring rod 613 and driven stirring rod 614 as soon as it is added, so as to prevent large-volume dregs from affecting the mixing of the liquid medicine. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
