DETAILED DESCRIPTION

[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For example, see Figure 1-Figure 6 , the utility model provides a technical solution:

[0025] A modulation device for preparing a herbicide comprises a stirring barrel 1 and a feeding barrel 2.

[0026] Specifically, the feed barrel 2 is provided with a plurality of circular arrays and fixedly installed on the outside of the mixing barrel 1, and the upper and lower ends of the side of the feed barrel 2 are respectively provided with a circulation outlet 22 and a circulation inlet 21, and both are connected to the inner cavity of the mixing barrel 1, such as Figure 2 and Figure 4 As shown, the liquid in the inner cavity of the mixing barrel 1 enters the inner cavity of the feeding barrel 2 through the circulation inlet 21, and the liquid in the inner cavity of the feeding barrel 2 enters the inner cavity of the mixing barrel 1 through the circulation outlet 22. The liquids in both inner cavities circulate, which can avoid the precipitation and stratification of the raw materials, thereby improving the mixing effect;

[0027] Secondly, a hopper 4 is fixedly connected to the upper end of the feed barrel 2, and an appropriate amount of required raw material powder is pre-poured into the inner cavity of the hopper 4. A vertically arranged transmission shaft 3 is rotatably installed in the inner cavity of the mixing barrel 1. The upper end of the transmission shaft 3 passes through the upper end surface of the feed barrel 2 and extends to the inner cavity of the hopper 4. The raw material powder in the inner cavity of the hopper 4 can enter the inner cavity of the feed barrel 2 along the periphery of the upper end of the transmission shaft 3. A hollow cylinder 23 is fixedly connected to the inner wall of the upper end of the feed barrel 2, and the hollow cylinder 23 is sleeved on the outer side of the transmission shaft 3. The upper end of the hollow cylinder 23 is connected to the inner cavity of the hopper 4. A discharge port 231 is provided on the surface of the hollow cylinder 23. After the raw material powder in the inner cavity of the hopper 4 enters the inner cavity of the hollow cylinder 23, it can be discharged from the lower cavity. The powdered material is discharged from the material port 231 and falls into the inner cavity of the feed barrel 2 under the action of gravity. A feeding auger 31 is fixedly arranged on the outer side of the upper end of the transmission shaft 3, and the feeding auger 31 is located in the inner cavity of the hollow cylinder 23. When the transmission shaft 3 rotates, the feeding auger 31 can transport the raw material powder at the bottom of the inner cavity of the hopper 4 to the inner cavity of the hollow cylinder 23, and discharge it from the feeding port 231 to the inner cavity of the feed barrel 2 and mix with the liquid in the inner cavity of the feed barrel 2. In addition, during the continuous rotation of the transmission shaft 3, the raw material powder can continuously enter the inner cavity of the feed barrel 2, thereby avoiding the accumulation of raw material powder caused by the one-time filling of a large amount of raw material powder. The lower end of the transmission shaft 3 is fixedly connected with a straight plate fan blade 32. Figure 4 As shown, when the liquid in the inner cavity of the mixing barrel 1 rotates and enters the inner cavity of the feeding barrel 2, the liquid impacts the straight fan blades 32 to drive the transmission shaft 3 to rotate, and at the same time, the liquid in the inner cavity of the feeding barrel 2 rotates accordingly, so that the raw material powder can be preliminarily mixed in the inner cavity of the mixing barrel 1, and then the liquid in the inner cavity of the feeding barrel 2 carries the raw material powder into the inner cavity of the mixing barrel 1 through the circulation outlet 22 for further stirring and mixing, and the liquid in the inner cavities of the feeding barrel 2 and the mixing barrel 1 can circulate, thereby improving the mixing effect of the raw material powder.

[0028] In order to limit the installation position of the straight fan blades 32, the straight fan blades 32 of the present application are provided in plurality and distributed in a circular array around the lower end of the transmission shaft 3. The straight fan blades 32 and the circulation inlet 21 are located at the same height position, ensuring that the liquid in the inner cavity of the mixing barrel 1 passes through the circulation inlet 21 and enters the inner cavity of the feed barrel 2. It can first impact the surface of the straight fan blades 32 and drive the transmission shaft 3 to rotate.

[0029] In order to increase the feeding speed of the raw material powder, the feeding port 231 of the present application is provided with multiple and distributed in a circular array around the lower end of the hollow cylinder 23 to increase the discharge speed of the raw material powder from the inner cavity of the hollow cylinder 23. The sealing arrangement between the lower end of the hollow cylinder 23 and the surface of the transmission shaft 3 can prevent the liquid in the inner cavity of the feed barrel 2 from entering the inner cavity of the hollow cylinder 23 as much as possible.

[0030] In order to make the liquid in the inner cavity of the feed barrel 2 flow upward, the present application also has a guide auger 33 fixedly arranged in the middle of the transmission shaft 3, and the rotation direction of the guide auger 33 is opposite to that of the unloading auger 31. When the transmission shaft 3 rotates, the guide auger 33 rotates accordingly and can drive the liquid in the inner cavity of the feed barrel 2 to flow upward, so that the liquid in the inner cavity of the feed barrel 2 is discharged from the circulation outlet 22 into the inner cavity of the mixing barrel 1 and forms a circulating flow. The inner wall of the feed barrel 2 is fixedly connected to a plurality of guide plates 24 distributed in a ring array. The cross-section of the guide plate 24 is "V"-shaped, and one side of the guide plate 24 is arc-shaped and tangent to the inner wall of the feed barrel 2. The middle part of the guide plate 24 faces the transmission shaft 3, combined with Figure 4 and Figure 5 It can be seen that when the liquid in the inner cavity of the feed barrel 2 rotates and flows, one side of the guide plate 24 can guide the liquid so that the liquid can be as close to the surface of the transmission shaft 3 as possible, so as to improve the upward conveying flow effect of the guide auger 33 on the liquid.

[0031] In order to make the liquid in the inner cavity of the mixing barrel 1 flow downward, the present application also has a mixing shaft 11 rotatably installed in the inner cavity of the mixing barrel 1, and a plurality of mixing blades 12 distributed in a circular array are fixedly connected to the upper end and the middle part of the mixing shaft 11. The mixing blades 12 are inclined and drive the water flow downward when rotating, such as Figure 2 and Figure 3 As shown, the stirring shaft 11 can drive the stirring blade 12 to rotate when rotating. The stirring blade 12 can stir and mix the liquid in the inner cavity of the stirring barrel 1 on the one hand, and on the other hand, it can also generate a downward squeezing force on the liquid in the inner cavity of the stirring barrel 1, so that the liquid in the inner cavity of the stirring barrel 1 can flow downward.

[0032] In order to deliver the liquid at the bottom of the mixing barrel 1 into the inner cavity of the feed barrel 2, the present application also has a plurality of arc blades 13 distributed in a ring array fixedly connected to the lower end of the mixing shaft 11. The arc blades 13 are arc-shaped and drive the water flow away from the mixing shaft 11 when rotating. When the arc blades 13 rotate, the liquid at the bottom of the mixing barrel 1 is stirred and an extrusion force is generated. Combined with the centrifugal force generated when the liquid rotates, it can ensure that the liquid at the bottom of the mixing barrel 1 can enter the inner cavity of the feed barrel 2 and impact the straight fan blades 32. The upper end of the mixing shaft 11 is driven by a motor, and the motor is installed on the upper surface of the mixing barrel 1. The motor applies power to the rotation of the mixing shaft 11.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
