[0002] The pesticide spraying machine is a relatively common pesticide spraying device, which mainly uses the principle in Bernoulli's principle that "when flowing at the same height, the greater the flow rate, the smaller the pressure" to make the pesticide in the medicine box of the pesticide spraying machine spray out from the nozzle, and spray the pesticide on the crops, so as to achieve the effect of preventing and controlling agricultural pests and diseases.

[0003] In the prior art, a patent such as the one with the publication number CN118177170A specifically discloses a backpack spraying device, which relates to the technical field of agricultural plant protection spraying. It solves the problem of low spraying efficiency when people hold atomizing instruments such as spray rods and spray guns by hand. Its characteristic is that this spraying device is a backpack spraying device that can be used for spraying with a backpack type and can also be used for spraying with a hook type. The backpack spraying brackets on both devices are movably connected to the left and right swing and rotation brackets. The left and right swing and rotation brackets can move left and right and up and down. The height during spraying is adjusted through a lead screw tie rod. A crank and a fixator are installed on the bushing of the inner ring of the rotating bearing. The fixator is used to fix various atomizing instruments such as spray rods and spray guns for spraying. Carrying the spraying device can perform spraying work in various ways such as left and right and up and down. It can also be connected with a multi-nozzle spray rod on the spraying device and walk to perform spraying work in various ways.

[0004] However, it is found that when using the above-mentioned pesticide spraying machine to spray pesticides on crops, before use, a variety of concentrated pesticides need to be added to the medicine box and mixed with water for dilution. In order to ensure that the liquid medicine can be evenly sprayed on the crops after dilution, stirring is usually required. The conventional operation is to tighten the round cover after adding the medicine to the medicine box, and then shake the medicine box manually to mix the medicine in the medicine box. However, the medicine box and the liquid medicine itself are very heavy, and shaking is quite laborious, and the shaking and mixing efficiency is low.

Detailed implementation

[0027] Refer to Figure 1 As shown, the present utility model provides a technical solution: a pesticide spraying device for agricultural pest control, including a medicine box 1, a shoulder strap 8 is fixedly connected to one side of the medicine box 1, a medicine injection hole is opened at the upper end of the medicine box 1, and a screw cap 2 is threadedly connected to the medicine injection hole. A pump body 3 is installed at the upper end of the medicine box 1, a connecting rod 5 is installed at the output end of the pump body 3, a rocker 4 is rotatably connected to one side of the medicine box 1, one end of the connecting rod 5 is movably connected to the rocker 4, a connecting pipe is communicated with the upper end of the pump body 3, and one end of the connecting pipe is installed with a spraying rod 6. A mixing mechanism 7 is provided on the inner wall of the screw cap 2.

[0028] Next, specifically describe the specific setting and function of its mixing mechanism 7.

[0029] Refer to Figures 2 to 5 As shown, in this implementation: the mixing mechanism 7 includes a pull rod 701, the pull rod 701 is fixedly connected to the screw cap 2, a lower end of the pull rod 701 is fixedly connected to an auger rod 702, a driving ring 703 is threadedly connected to the auger rod 702, a plurality of fixed brackets 704 are fixedly connected to an arc surface of the driving ring 703, and a plurality of stirring rods 705 are uniformly and fixedly connected to the fixed brackets 704. An inner bottom wall of the medicine box 1 is fixedly connected with a support frame 706, and an upper end of the support frame 706 is movably connected to the driving ring 703, achieving the effect that after unscrewing the screw cap 2 and adding concentrated pesticide into the medicine box 1, the screw cap 2 can be pulled up and down, so that the screw cap 2 drives the auger rod 702 to move up and down by means of the pull rod 701, and the driving ring 703 is driven to rotate by means of the auger rod 702, thereby using the stirring rod 705 to mix the liquid medicine in the medicine box 1, so that the liquid medicine can be fully diluted and evenly sprayed on the crops for pest control. A slip ring 707 is fixedly connected to a bottom end of the arc surface of the driving ring 703, and an upper end of the support frame 706 is movably connected to the slip ring 707, achieving the effect that the driving ring 703 can be normally supported by means of the support frame 706 without affecting the normal rotation of the driving ring 703.

[0030] The arc surface of the pull rod 701 is fixedly connected with a fixed plate 708. Springs 709 are fixedly connected to the upper sides of both ends of the fixed plate 708. After pulling up the rotary cover 2 upward, causing the rotary cover 2 to drive the pull rod 701 to move upward and drive the driving ring 703 to rotate, when the rotary cover 2 is released, the elastic force of the spring 709 can be used to drive the pull rod 701 to quickly move downward. By repeating such operations, the stirring rod 705 can be quickly driven to rotate to mix the liquid medicine in the medicine box 1. The upper end of the spring 709 is fixedly connected with a sliding buckle 710. The upper ends of the two sliding buckles 710 are slidably connected to the same clamping ring 711. The clamping ring 711 is fixedly connected to the inner wall of the medicine box 1 corresponding to the edge of the medicine injection hole, achieving the effect of ensuring the normal telescopic movement of the spring 709 on the premise of not affecting the normal rotation of the rotary cover 2 and screwing it onto the medicine box 1 with threads. The cross-sections of the sliding buckle 710 and the clamping ring 711 are in the shape of "concave" and "convex" respectively. An expansion rod 712 is arranged inside the spring 709. The upper and lower ends of the expansion rod 712 are fixedly connected with the sliding buckle 710 and the fixed plate 708 respectively, achieving the effect of restricting the elastic force direction of the spring 709. The inner wall of the medicine injection hole of the medicine box 1 is fixedly connected with a filter screen 713. A reserved hole is opened at the central position of the filter screen 713. The pull rod 701 slides through the reserved hole of the filter screen 713, achieving the effect of simply filtering the injected liquid medicine, thereby avoiding debris such as grass clippings from entering the medicine box 1 and causing blockage when the spraying rod 6 sprays medicine.

[0031] Working principle: Before spraying pesticides on crops, first rotate and open the rotary cover 2, then pull up the rotary cover 2 to create a certain gap between the rotary cover 2 and the medicine injection hole of the medicine box 1, and then pour the pesticides into the medicine box 1. At this time, the filter screen 713 plays the role of simply filtering debris such as grass clippings, and then pour enough clean water into the medicine box 1. When the pesticides need to be stirred, directly pull up the rotary cover 2. At this time, the rotary cover 2 drives the pull rod 701 to move upward. The pull rod 701 drives the auger rod 702 to move upward. The auger rod 702 drives the driving ring 703 to rotate by means of the auger blades. The support frame 706 plays the role of supporting the driving ring 703 on the premise of not affecting the normal rotation of the driving ring 703. The rotation of the driving ring 703 drives the stirring rod 705 on the fixed frame 704 to rotate. The stirring rod 705 will then stir and mix the liquid medicine in the medicine box 1. While pulling up the rotary cover 2 to drive the pull rod 701 to move upward, the fixed plate 708 will move upward. At this time, the spring 709 is in a compressed state. After the rotary cover 2 is pulled up to drive the driving ring 703 to rotate, release the rotary cover 2. At this time, the spring 709 will apply a downward elastic force to the fixed plate 708 through the sliding buckle 710. The fixed plate 708 will drive the pull rod 701 to move downward, and the auger rod 702 will drive the driving ring 703 to move in the reverse direction, thereby realizing the reverse rotation of the stirring rod 705. By repeating this process, the liquid medicine in the medicine box 1 can be quickly mixed by means of the stirring rod 705.

[0032] After the pesticide liquid medicine is mixed evenly, press down the screw cap 2, and then screw the screw cap 2 tightly on the upper end of the medicine injection hole of the medicine box 1. When rotating the screw cap 2, the sliding buckle 710 will rotate with the snap ring 711, so that the normal rotation and tightening effect of the screw cap 2 can be ensured without affecting the normal release of the telescopic elastic force of the spring 709. Then, carry the medicine box 1 on the back with the help of the shoulder strap 8. Then, hold the spraying rod 6 with one hand, and repeatedly press the rocker 4 with the other hand. The rocker 4 will drive the connecting rod 5 to reciprocate up and down to pull the pump body 3, so that the mixed liquid medicine in the medicine box 1 can be sprayed out from the spraying rod 6 by means of the pump body 3 and using Bernoulli's principle, so as to achieve the effect of spraying pesticides on crops for pest control.
