DETAILED DESCRIPTION

[0026] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. EXAMPLE

[0027] As shown in the accompanying Figure 1 to the accompanying Figure 6 :

[0028] The utility model provides a kind of agricultural sprayer, including sprayer main body 1, manual pressure mechanism 2, mixer 3, filter 4, infusion tube 5, spray rod 6 and mixing assembly, manual pressure mechanism 2 is installed in sprayer main body 1 side;Mixing device 3 is installed in sprayer main body 1 side;Filter 4 is installed in sprayer main body 1 side;Infusion tube 5 is fixedly installed in filter 4 side;Spray rod 6 is fixedly installed in infusion tube 5 one end;Mixing assembly is arranged in the inside of mixing device 3.

[0029] Among them, mixing assembly includes: rotating shaft 303 and stirring paddle 306, rotating shaft 303 is rotatably connected in the inside of sprayer main body 1, and one end of rotating shaft 303 is rotatably connected in the inside of mixing device 3;Stirring paddle 306 is provided with multiple groups, and multiple groups of stirring paddle 306 are fixedly installed on the outside of rotating shaft 303.

[0030] Among them, mixing assembly further includes: through slot 301 and transmission roller 302, through slot 301 is opened in the inside of mixing device 3;Transmission roller 302 is provided with two groups, and two groups of transmission roller 302 are rotatably connected in the inside of through slot 301 two sides.

[0031] Among them, mixing assembly further includes: pull rope 304, pull ring 305 and elastic coil spring 307, one end of pull rope 304 is fixedly connected in one end of rotating shaft 303;Pull ring 305 is fixedly installed in one end of pull rope 304;Elastic coil spring 307 one end is fixedly connected in the inside of mixing device 3, and the other end of elastic coil spring 307 is fixedly connected on the outside of rotating shaft 303.

[0032] The specific usage and function of this embodiment are as follows:

[0033] After adding pesticide and water into the sprayer body 1, the operator pulls the pull ring 305. As the pull ring 305 moves, it pulls the rope 304 wound around one end of the rotating shaft 303. With the rope 304 stretched, the rotating shaft 303 rotates synchronously, during which the elastic coil spring 307 is compressed and stores energy. The rotation of the rotating shaft 303 drives the stirring blades 306 to rotate, thereby efficiently mixing the pesticide and water within the sprayer body 1.

[0034] When the pull ring 305 is released, the elastic coil spring 307, using its own elastic potential energy, drives the rotating shaft 303 to rotate in the opposite direction. At this time, the stirring blade 306 continues to rotate, further agitating the internal liquid. Simultaneously, the pull rope 304 begins to rewind around one end of the rotating shaft 303. During the extension and retraction process, the pull rope 304 passes through the through groove 301. During this period, the transmission roller 302 not only guides the extension and retraction of the pull rope 304 but also adheres impurities on the surface of the pull rope 304 to its own surface, effectively preventing the problem of reduced service life due to impurities adhering to the pull rope 304.

[0035] The operator only needs to repeatedly pull and release the pull ring 305 to make the stirring blade 306 continuously stir in both directions, so that the pesticide and water inside the sprayer body 1 can be fully mixed and achieve the ideal mixing effect. Example

[0036] Based on Example 1, such as Figures 1 to 6 As shown, it also includes: an interception component, which is set inside filter 4.

[0037] The interception component includes a transmission plate 401 and a handle 402. The transmission plate 401 is horizontally slidably connected inside the filter 4; the handle 402 is fixedly installed on both sides of the transmission plate 401.

[0038] The interception assembly also includes: a limiting pin 403, a reset spring 404, and a limiting hole 407. The limiting pin 403 is slidably connected to the upper part of the filter 4; the reset spring 404 is installed on the outside of the limiting pin 403; and two sets of limiting holes 407 are provided, which are opened on the upper part of the transmission plate 401.

[0039] The interception component also includes: a slot 405 and a filter screen 406. There are two sets of slots 405, which are located on both sides inside the transmission plate 401. There are two sets of filter screens 406, which are snapped into the two sets of slots 405.

[0040] The specific usage and function of this embodiment are as follows:

[0041] When the inside of the sprayer body 1 is pressurized by the manual pressurizing mechanism 2, the pesticide liquid is sprayed from the spray rod 6 through the liquid delivery pipe 5 to perform agricultural work. When the pesticide liquid passes through the liquid delivery pipe 5, it passes through the filter 4, and the filter screen 406 inside the transmission plate 401 filters the pesticide liquid, intercepting impurities, particles and undissolved pesticide lumps in the pesticide liquid.

[0042] When the flow of the pesticide liquid sprayed by the spray rod 6 decreases, it indicates that the filter screen 406 in this group is blocked. The limit pin 403 is pulled out of the limit hole 407 and compresses the return spring 404, canceling the limit of the transmission plate 401, pulling the handle 402, and the handle 402 drives the transmission plate 401 to slide inside the filter 4, so that the two groups of filter screens 406 inside the transmission plate 401 are quickly replaced. The originally blocked filter screen 406 is quickly replaced, and the other group of filter screens 406 that are unblocked are aligned with the liquid delivery pipe 5 to continue filtering, making it convenient for the operator to continue agricultural spraying work. After this spraying work is completed, the filter screen 406 can be removed through the clamping slot 405 for maintenance.
