Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, specifically to a pest and disease treatment device for high-yield winter wheat seed cultivation. Background Technology

[0002] Manual sprayers are a common type of pest and disease control device used in the cultivation of high-yield winter wheat seeds. They consist of a welded liquid tank, a pump, an air chamber, a water outlet pipe, a handle switch, a spray bar, a nozzle, a rocker arm, and a shoulder strap system. They are suitable for small-area wheat fields or localized pest and disease control.

[0003] Manual sprayers are compact in structure and relatively easy to operate. They can be carried on the body, making them convenient for moving and working in wheat fields. They can generate high spray pressure and have a good atomization effect, which can evenly spray the pesticide onto wheat seedlings.

[0004] When preparing pesticide solutions outdoors, many farmers are accustomed to doing so directly in open containers, such as large buckets or basins. Impurities from the surrounding environment can easily get in, and the wind may blow dust and plant debris into the container. Moreover, some pesticides are in powder form, and when the pesticide mixes with impurities during stirring, undissolved powder particles will remain in the solution. This can cause undissolved powder particles to easily enter the nozzle and cause blockage when using a manual sprayer.

[0005] Therefore, a pest and disease treatment device for high-yield winter wheat seed cultivation is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pest and disease treatment device for high-yield winter wheat seed cultivation, in order to solve the problem that when pesticides are mixed with impurities during stirring, undissolved pesticide powder particles remain in the solution, causing undissolved pesticide powder particles to easily enter the nozzle and cause blockage when using a manual sprayer.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pest and disease treatment device for high-yield winter wheat seed cultivation includes a liquid tank with an air chamber, and a filter device fixedly connected to the inside of the liquid tank. The filter device includes a liquid inlet, with a sealing cap spirally connected to the upper end of the liquid inlet. A limit plate is fixedly connected to the inside of the liquid inlet, and a filter plate is installed inside the limit plate. A rotating shaft is rotatably connected to the inner wall of the liquid inlet, and a water-blocking folding plate is fixedly connected to the outside of the rotating shaft. An impact block is rotatably connected to the outside of another rotating shaft. A guide rod is fixedly connected to the side of the impact block away from the filter plate, and the guide rod passes through the liquid inlet and is slidably connected to the inside of the liquid tank. The filter plate includes a filter screen, with a retaining ring fixedly connected to the outside of the filter screen. A support rod is fixedly connected to the bottom of the filter screen, and the support rod passes through the bottom of the filter screen and is fixedly connected to a counterweight.

[0009] As a further optimization of this utility model, a pump is installed on the outside of the liquid tank, a spray bar is fixedly connected to the outside of the liquid tank, a nozzle is fixedly connected to one end of the spray bar, and an annular groove is provided on the inner side of the limiting plate.

[0010] As a further optimization of this utility model, two rotating shafts are provided, which are located at both ends of the water-blocking folding plate. The rotating shafts are parallel to each other, and the center points of the rotating shafts are not on the same horizontal line.

[0011] As a further optimization of this utility model, two water-blocking folding plates are provided. The water-blocking folding plates are arranged symmetrically with the center line of one side of the impact block as the axis. The length of the water-blocking folding plate after unfolding is equal to two-thirds of the inner diameter of the liquid inlet. The vertical cross-section of the water-blocking folding plate is serrated. The included angle between the water-blocking folding plate and the guide rod is 30°.

[0012] As a further optimization of this utility model, the impact block is perpendicular to the guide rod on one side, the impact block is rectangular in shape, the guide rod has a T-shaped vertical cross-section, the guide rod is located outside the liquid tank, and the impact block is equal to two-thirds of the inner diameter of the liquid inlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the filter screen precisely intercepts undissolved powder particles, plant residues, and other solid impurities, effectively filtering them.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A pest and disease treatment device for high-yield winter wheat seed cultivation includes a liquid tank 1 with an air chamber, and a filter device 5 fixedly connected to the inside of the liquid tank 1. The filter device 5 includes an inlet 51, a sealing cap 52 screwed to the upper end of the inlet 51, a limiting plate 53 fixedly connected to the inside of the inlet 51, a filter plate 54 installed inside the limiting plate 53, a rotating shaft 55 rotatably connected to the inner wall of the inlet 51, a water-blocking folding plate 56 fixedly connected to the outside of the rotating shaft 55, an impact block 57 rotatably connected to the outside of another rotating shaft 55, a guide rod 58 fixedly connected to the side of the impact block 57 away from the filter plate 54, and the guide rod 58 slidably connected to the inside of the liquid tank 1 through the side of the inlet 51. The filter plate 54 includes a filter screen 541, a retaining ring 542 fixedly connected to the outside of the filter screen 541, and a support rod 543 fixedly connected to the bottom of the filter screen 541, the support rod 543 passing through the bottom of the filter screen 541 and fixedly connected to a counterweight 544.

[0028] As a further implementation of the above technical solution: one side of the impact block 57 is perpendicular to the guide rod 58. The impact block 57 is rectangular in shape, and the vertical section of the guide rod 58 is T-shaped. The guide rod 58 is located on the outside of the liquid tank 1. The impact block 57 is equal to two-thirds of the inner diameter of the liquid inlet 51, providing a stable and powerful contact surface for the impact counterweight 544, ensuring that the impact force is transmitted evenly, enhancing the shaking effect of the counterweight 544, and thus enabling the filter screen 541 to better perform its filtering function.

[0029] As a further implementation of the above technical solution: the center points of the filter screen 541 and the retaining ring 542 are located on the same vertical line, the vertical cross-section of the retaining ring 542 is L-shaped, and the outer side of the retaining ring 542 is engaged with the inner side of the annular groove provided on the inner side of the limiting plate 53, which can accurately intercept solid impurities and ensure the purity of the medicine liquid.

[0030] As a further implementation of the above technical solution: two pivots 55 are provided, and the two pivots 55 are located at both ends of the water-blocking folding plate 56. The pivots 55 are parallel to each other, and the center points of the pivots 55 are not on the same horizontal line. As a joint hub for the flexible movement of the water-blocking folding plate 56, the water-blocking folding plate 56 can be freely unfolded and folded according to the needs.

[0031] As a further implementation of the above technical solution: a pump 2 is installed on the outside of the liquid tank 1, a spray bar 3 is fixedly connected to the outside of the liquid tank 1, a nozzle 4 is fixedly connected to one end of the spray bar 3, an annular groove is provided on the inner side of the limiting plate 53, and the retaining ring 542 of the limiting plate 53 and the filter plate 54 are precisely matched to provide a stable support structure for the filter screen 541.

[0032] As a further implementation of the above technical solution: two water-blocking folding plates 56 are provided. The water-blocking folding plates 56 are symmetrically arranged with the center line of one side of the impact block 57 as the axis. The length of the water-blocking folding plate 56 after unfolding is equal to two-thirds of the inner diameter of the liquid inlet 51. The vertical cross-section of the water-blocking folding plate 56 is serrated. The angle between the water-blocking folding plate 56 and the guide rod 58 is 30°. This effectively prevents the filtered liquid from flowing out from specific leak-prone parts, ensuring that the liquid flows into the liquid tank 1 in an orderly manner along the preset route. The serrated structure can disperse the impact force of the water flow and enhance its stability under the impact of the liquid.

[0033] As a further implementation of the above technical solution: the center point of the support rod 543 and the counterweight 544 is on the same vertical line as the center point of the retaining ring 542, the center point of the counterweight 544 is on the same parallel line as the center point of the impact block 57, and the upper end of the support rod 543 is set inside the filter screen 541. After being hit by the impact block 57, it shakes due to inertia, causing the attached impurities to fall off due to the shaking and maintaining the good permeability of the mesh.

[0034] Workflow: First, open the sealing cap 52 on the liquid tank 1, and pour the prepared liquid for controlling winter wheat pests and diseases into the liquid tank 1 through the inlet 51. During the addition of the liquid, it will first pass through the filter device 5 for preliminary filtration. The filter screen 541 is locked in place by the retaining ring 542 and the slot at the upper end of the limiting plate 53, which can securely install it in the inlet 51 to prevent displacement or falling off under the impact of the liquid. The support rod 543 at the bottom of the filter screen 541 passes through the bottom of the filter screen 541 and is connected to the counterweight 544. During the pouring of the liquid, the user needs to slide the guide rod 58 inward. At this time, the rotating shaft 55 will rotate to a certain extent. The sliding of the guide rod 58 will drive the water-blocking folding plate 56 to move and unfold, which can effectively allow the filtered liquid to flow into the connection between the inlet 51 and the support rod 543, resulting in As the liquid medicine flows outward, the impact block 57 strikes the counterweight block 544. The counterweight block 544, impacted by this, will shake due to its inertia. This shaking will cause the filter screen 541 to shake as well. When the filter screen 541 shakes, tiny impurities that might have adhered to and accumulated on its mesh will become less stable due to the dynamic changes in the filter screen. These impurities, under the combined effect of the slight vibration and the impact of the water flow, are more easily detached from the surface of the filter screen 541 and return to the liquid medicine flow. During this shaking process, the flow of the liquid medicine through the filter screen 541 is no longer uniform and stable, but rather forms a certain turbulence. This turbulence allows the liquid medicine to contact all areas of the filter screen 541 more evenly, enabling the entire filter screen 541 to fully perform its filtering function, maximizing the interception of impurities and improving filtration quality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
