Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a liquid mixing and stirring device for a farmland sprayer. Background Technology

[0002] A farm sprayer is a type of agricultural machinery, specifically a plant protection machine. It is mainly used in agricultural production to disperse liquids (such as pesticides, water, fertilizers, etc.) into tiny droplets and spray them evenly onto crops.

[0003] Because some of the dissolved substances in the liquid tend to settle at the bottom of the storage tank under gravity if it is not stirred for a long time, in order to ensure that the dissolved substances do not cause the storage tank to separate due to sedimentation, thus affecting the effect after spraying, it is often necessary to use a liquid mixing agitator to mix and stir the liquid to ensure that the liquid can be continuously and evenly mixed during the spraying process.

[0004] Currently, existing equipment can achieve the effect of ensuring the mixing of pesticide solution through simple stirring. However, in actual use, the bottom of the stirrer is often equipped with a pipe connected to the atomizer. Since the diameter of the pipe is often small, the liquid inside the pipe is often difficult to mix with the liquid in the storage tank. Furthermore, the dissolved substances in the pesticide solution in this area are prone to sticking to the inner wall of the pipe when passing through this area, which can lead to pipe blockage and affect the subsequent spraying effect. Therefore, a pesticide solution mixing stirrer for farmland sprayers is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a pesticide mixing and stirring device for a farmland sprayer, comprising a tank body 1, a feed hopper 2 fixedly connected to the top of the tank body 1, the feed hopper 2 being shaped like a frustum, with the top side length of the feed hopper 2 being greater than the bottom side length, the feed hopper 2 being hollow with openings at both the top and bottom, and a discharge pipe 3 fixedly connected to the bottom of the tank body 1, the discharge pipe 3 being hollow cylindrical with openings at both the top and bottom.

[0035] Reference Figure 2 , Figure 4 and Figure 7The discharge pipe 3 and the tank 1 are both equipped with an anti-clogging mechanism 4. The anti-clogging mechanism 4 includes a rotating pipe 41, which is hollow and has an open top and a closed bottom. The outer wall of the rotating pipe 41 is rotatably connected to the inner wall of the tank 1. A reciprocating screw 42 is fixedly connected to the bottom of the rotating pipe 41. The reciprocating screw 42 is concentric with the rotating pipe 41. A slider 43 is provided on the outside of the reciprocating screw 42. A connecting frame 44 is fixedly connected to the outer wall of the slider 43. A moving ring 45 is fixedly connected to the bottom of the connecting frame 44. The moving ring 45 is slidably connected to the discharge pipe 3. The moving ring 45 can... It can only move up and down relative to the discharge pipe 3, but cannot rotate relative to the discharge pipe 3. The bottom end of the moving ring 45 is fixedly connected to the mounting ring 47. The inner wall of the mounting ring 47 is piston-connected to the connecting block 48. Through the piston connection, it is ensured that the liquid medicine cannot enter the interior of the mounting ring 47. The bottom end of the connecting block 48 is fixedly connected to the cleaning ring 410. The outer wall of the cleaning ring 410 fits against the inner wall of the discharge pipe 3.

One end of the spring 49 is fixedly connected to the top end of the connecting block 48, and the other end of the spring 49 is fixedly connected to the inner wall of the mounting ring 47.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The discharge pipe 3 is equipped with a vibration assembly 46, which includes a moving groove 461. A piston plate 462 is connected to the inner wall of the moving groove 461. The side of the piston plate 462 near the middle of the discharge pipe 3 is curved, and the curvature is consistent with the curvature of the inner curved surface of the discharge pipe 3. The curved surface ensures that the piston plate 462 will not affect the use of the equipment due to a protruding position. A control ball 463 is fixedly connected to the end of the piston plate 462 near the middle of the discharge pipe 3. The control ball 463 is hemispherical. The end of the piston plate 462 away from the control ball 463 is elastically connected to the inner wall of the moving groove 461 by a second spring 464. One end of the second spring 464 is fixedly connected to the end of the piston plate 462 away from the control ball 463, and the other end of the second spring 464 is fixedly connected to the inner wall of the moving groove 461. The difference between the outer diameter of the mounting ring 47 and the outer diameter of the moving ring 45 is greater than the diameter of the control ball 463.

[0037] Reference Figure 2 , Figure 3 and Figure 6The tank body 1 is equipped with a stirring mechanism 5, which includes a mounting groove 51. A fixing rod 52 is fixedly connected to the inner wall of the tank body 1. The fixing rod 52 is located inside the rotating tube 41, and the rotating tube 41 and the fixing rod 52 are concentrically arranged. The outer diameter of the fixing rod 52 is smaller than the inner diameter of the rotating tube 41. A power assembly 53 is installed inside the mounting groove 51. The power assembly 53 includes a motor 531. The outer wall of the motor 531 is fixedly connected to the inner wall of the mounting groove 51. A first spur gear 532 is fixedly connected to the output shaft of the motor 531. A second spur gear is fixedly connected to the outer wall of the rotating tube 41. 533, the second spur gear 533 is concentrically arranged with the rotating tube 41, the first spur gear 532 meshes with the second spur gear 533, the outer wall of the rotating tube 41 is fixedly connected to the stirring frame 54, the inner wall of the stirring frame 54 is rotatably connected to the rotating rod 55, the rotating rod 55 is located in the middle of the stirring frame 54, the outer wall of the rotating rod 55 is fixedly connected to the stirring blade 56, the outer wall of the rotating rod 55 penetrates the inner wall of the rotating tube 41, the end of the rotating rod 55 near the middle of the rotating tube 41 is fixedly connected to the first bevel gear 57, the outer wall of the fixed rod 52 is fixedly connected to the second bevel gear 58, the first bevel gear 57 meshes with the second bevel gear 58.

[0038] Working principle: When in use, the staff adds the medicine through the feed hopper 2 and starts the motor 531.

[0039] When the motor 531 rotates, it drives the first spur gear 532 to rotate, and through the first spur gear 532, it drives the second spur gear 533 to rotate, thereby causing the second spur gear 533 to drive the rotating tube 41 to rotate.

[0040] During the rotation of the rotating tube 41, the reciprocating screw 42 is driven to rotate synchronously with it. Therefore, the slider 43 moves up and down during the rotation of the reciprocating screw 42, thereby driving the connecting frame 44 and the moving ring 45 to move up and down.

[0041] As the moving ring 45 moves up and down, it drives the mounting ring 47 to move up and down. The mounting ring 47, in turn, drives the spring 49 and the connecting block 48 to move up and down. Meanwhile, as the connecting block 48 moves up and down, it drives the cleaning ring 410 to move up and down. Therefore, the cleaning ring 410 can move up and down and clean the inner wall of the discharge pipe 3 during the movement.

[0042] When the cleaning ring 410 moves downward to contact the upper spherical surface of the control ball 463, the control ball 463 cannot retract immediately due to the elastic force of the second spring 464. Therefore, the cleaning ring 410 cannot move at this time. However, due to the continuous downward movement of the mounting ring 47, the mounting ring 47 and the connecting block 48 move relative to each other, thereby compressing the first spring 49.

[0043] When the spring 49 is compressed, its elastic force increases, and the cleaning ring 410 pushes the control ball 463 downward. Since there is no obstruction below the cleaning ring 410 after it leaves the position of the control ball 463, the cleaning ring 410 can move downward quickly under the elastic force of the spring 49. Afterward, it vibrates as the spring 49 rebounds, causing the impurities adhering to it to fall off. The same applies when the cleaning ring 410 moves upward.

[0044] Meanwhile, as the rotating tube 41 rotates, it also drives the stirring frame 54 to rotate, and as the stirring frame 54 rotates, it drives the rotating rod 55 to rotate around the axis of the rotating tube 41. Therefore, the bevel gear 57 rotates synchronously with it.

[0045] As the bevel gear 57 rotates, its teeth are obstructed by the bevel gear 58, so the bevel gear 57 is forced to rotate, which in turn drives the rotating rod 55 and the stirring blade 56 to rotate, thereby causing the stirring blade 56 to rotate up and down, thus achieving the effect of fully mixing liquids at different heights inside the tank 1 and preventing the liquid from separating.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
