[0013] (1) A herbicide temporary storage box is used to temporarily store a large amount of herbicides. The quantitative tube, the feed port, etc. are used to automatically and evenly fill the herbicide in the herbicide temporary storage box into the inner cavity of the quantitative tube. As the quantitative tube rotates, the herbicide is automatically discharged from the discharge port. Since the filling space of the herbicide inside the quantitative tube is the same in size, the quantitative delivery of the herbicide is achieved.

[0015] (2) By filling the mixing box with water flow, the buoyancy is used to make the airbag drive the slide plate to rise. When the top cover moves to the preset height, it provides a certain upward driving force to the U-shaped warning plate to realize the upward movement of the U-shaped warning plate. The movement of the U-shaped warning plate is used to remind the staff that the solution filling and feeding are completed. Compared with the observation of a single scale, the movement of the U-shaped warning plate is more noticeable, which is conducive to ensuring the quantitative delivery of water capacity.

[0023] See also Figure 1-Figure 4 The utility model provides an embodiment: a quantitative feeding structure of a herbicide mixing device, comprising a mixing box 1,

[0024] A placement hole 4 is provided on one side of the top of the mixing box 1 away from the temporary herbicide storage box 6, and a U-shaped warning plate 3 is passed through the placement hole 4. Both bottom ends of the U-shaped warning plate 3 extend into the interior of the mixing box 1. An early warning trigger mechanism 2 is provided inside the mixing box 1 below the U-shaped warning plate 3.

[0025] The early warning trigger mechanism 2 includes a guide rod 201 installed inside the mixing box 1, and a slide plate 202 is provided on the outer sleeve of the guide rod 201, a top sleeve 203 is installed on the top of the slide plate 202, and the top of the top sleeve 203 corresponds to the bottom end position of the U-shaped early warning plate 3, and an air bag 204 is provided on the bottom end of the slide plate 202;

[0026] Specifically, Figure 1 , Figure 4 As shown, when in use, the buoyancy effect is utilized to make the airbag 204 drive the top cover 203 to rise, and push the U-shaped warning plate 3 to move, and the activity of the U-shaped warning plate 3 is utilized to achieve the effect of reminder, and its reminder effect is more noticeable than direct scale observation;

[0027] An agitator 11 is provided at the bottom end of the mixing box 1, a water inlet pipe 10 is connected to the top of one side of the mixing box 1, a liquid discharge pipe 12 is connected to the bottom end of one side of the mixing box 1, a herbicide temporary storage box 6 is installed on one side of the top of the mixing box 1, and a limit box 8 is installed on the top of the mixing box 1 below the herbicide temporary storage box 6, a feed port 14 is provided on one side of the top of the limit box 8, and a connecting pipe 7 is connected between the feed port 14 and the herbicide temporary storage box 6, a discharge port 15 is provided on the other side of the bottom of the limit box 8, and the discharge port 15 and the feed port 14 are symmetrically distributed about the center of the limit box 8, and the cross-sections of the discharge port 15 and the feed port 14 are both fan-shaped, and the interior of the limit box 8 is filled with a quantitative tube 9;

[0028] The outer diameter of the quantitative tube 9 is matched with the inner diameter of the limit box 8, and the height of the quantitative tube 9 is matched with the inner height of the limit box 8. At the same time, the quantitative tube 9 and the limit box 8 are coaxially distributed, and the quantitative tube 9 and the limit box 8 are rotatably connected;

[0029] A cross partition 13 is installed inside the quantitative tube 9;

[0030] The cross partition 13 divides the internal space of the quantitative tube 9 into four equal parts, and the top view cross-sections of the four equal parts are all fan-shaped, and the cross-sectional area of ​​the fan-shaped cross-section is larger than the cross-sectional area of ​​the feed port 14 and the discharge port 15;

[0031] Specifically, Figure 1 , Figure 2As shown, when in use, the limit box 8 and the quantitative tube 9 are matched, and the quantitative tube 9 rotates inside the limit box 8, so that the herbicide is filled from one side to one inner cavity of the quantitative tube 9. When the inner cavity rotates, the herbicide in the other inner cavity can be automatically discharged. Since the inner cavity space size is the same, the quantitative discharge effect is guaranteed, and at the same time, the weighing operation of the herbicides one by one is avoided, thereby improving convenience.

[0032] A rotation adjustment mechanism 5 is provided at the top of the cross partition 13, and the rotation adjustment mechanism 5 passes through the top of the limit box 8 and extends to the outside of the mixing box 1;

[0033] The rotation adjustment mechanism 5 includes a rotating rod 501 installed at the center of the top of the cross partition 13, and the top of the rotating rod 501 passes through the top of the limit box 8 and the top of the mixing box 1 in sequence and is installed with a knob 502, and the outer side of the knob 502 is evenly installed with equal division strips 503, and the top of the mixing box 1 on one side of the knob 502 is installed with a calibration pointer 504;

[0036] Working principle: When the utility model is used, a large amount of herbicide is first introduced into the herbicide temporary storage box 6, so that the herbicide falls into the interior of the cross partition 13 through the connecting pipe 7 under the action of gravity, and then enters a cavity inside the quantitative tube 9, so as to realize automatic quantitative filling of the herbicide;

[0037] Secondly, the aqueous solution is injected into the mixing box 1 through the water inlet pipe 10. As the liquid level rises, the airbag 204 drives the slide plate 202 to rise along the guide rod 201 under the action of buoyancy, so that the top cover 203 rises synchronously. When the liquid level reaches a certain height, the top cover 203 contacts and squeezes the bottom end of the U-shaped warning plate 3, so that the top end of the U-shaped warning plate 3 moves upward along the placement hole 4. The movement of the U-shaped warning plate 3 is used to remind the staff that the filling of the aqueous solution is completed, and then the water inlet pipe 10 is closed;

[0038] Finally, the knob 502 is turned to rotate the rotating rod 501 and drive the metering tube 9 to rotate. When the dividing strip 503 corresponds to the position of the calibration pointer 504, the metering tube 9 rotates the bottom of the cavity filled with the herbicide to the top of the discharge port 15, and then the herbicide automatically falls into the interior of the mixing box 1, and the single delivery amount of the herbicide is made the same, reducing the successive weighing of the herbicide, and then the agitator 11 is started to mix the herbicide and the aqueous solution, and then discharged from the discharge pipe 12 for use.
