[0036] like Figure 2 , Figure 3 , Figure 4 As shown, the horizontal reciprocating mechanism includes a partition 14, a connecting shaft 8, a cam 16, a push rod 17, a moving block 20, a first elastic member 18 and a rotating assembly. The partition 14 is horizontally arranged in the box body 1, and the edge of the partition 14 is fixedly connected to the inner wall of the box body 1, dividing the box body 1 from top to bottom into a driving chamber 141 and a mixing chamber 142. The second tank body 5 is located close to the driving chamber 141 and is unidirectionally connected to the mixing chamber 142, so that the mixed liquid of the second tank body 5 flows into the mixing chamber 142 in a unidirectional manner.

In the initial stage, the nearest end of the cam 16 contacts the moving block 20, and the lower part of the moving block 20 is slidably connected with the partition 14, so that the moving block 20 can be driven to move horizontally by the rotation of the cam 16. The first elastic member 18 is sleeved on the push rod 17 and is located between the moving block 20 and the inner wall of the driving chamber 141. The two ends of the first elastic member 18 are respectively connected to the moving block 20 and the inner wall of the driving chamber 141. The elastic force of the elastic member 18 facilitates the reset of the moving block 20 after it moves toward the second tank body 5. The rotating assembly is arranged in the mixing chamber 142. The rotating assembly is used to drive the connecting shaft 8 to rotate. The connecting shaft 8 drives the cam 16 to rotate. The cam 16 drives the moving block 20 to move toward the second tank body 5 and resets under the elastic force of the first elastic member 18. In this way, the moving block 20 is continuously driven to move horizontally back and forth. The moving block 20 drives the piston 15 to move in the second tank body 5 through the push rod 17, so that the pressure in the second tank body 5 changes.

[0037] like Figure 2 , Figure 5 As shown, a limit groove 27 is horizontally opened at the upper part of the partition 14 near the moving block 20, and a limit block 28 is arranged in the limit groove 27. The limit block 28 is slidably connected to the inner wall of the limit groove 27 along the length direction of the limit groove 27, and the upper part of the limit block 28 is connected to the lower part of the moving block 20, so that the moving block 20 is more stable when moving along the upper part of the partition 14.

The connection shaft 8 is rotatably sealed and connected to the lower part of the first tank body 4. The connection shaft 8 is connected to the cam 16 through a clutch assembly. There are multiple connection shafts 8, and the multiple connection shafts 8 are evenly arranged around the transmission shaft 9, that is, there are also multiple first tank bodies 4. Each first tank body 4 is provided with a second stirring mechanism, and each first tank body 4 also corresponds to a second tank body 5. When the motor 7 is started, the transmission shaft 9 and the multiple connection shafts 8 can be driven to rotate at the same time. The transmission shaft 9 drives the first stirring mechanism to rotate, and the multiple connection shafts 8 drive the multiple second stirring mechanisms to rotate. Since a variety of different pesticides need to be added in numerical order, the connection with the cam 16 can be disconnected by the clutch assembly on each connection shaft 8, and then a variety of different pesticides and a small amount of water can be added to the multiple first tank bodies respectively. 4 is stirred by the corresponding second stirring mechanism. After the preliminary mixing is completed, each connecting shaft 8 is connected to the cam 16 in sequence, and the mixed liquid in each first tank body 4 is added to the mixing chamber 142 in sequence. After completion, each connecting shaft 8 continues to be connected to the cam 16, and air is continuously injected into the mixing chamber 142 at a certain speed, so that the mixed liquid in the mixing chamber 142 forms local vortices at multiple different positions, further promoting the formation of turbulence, enhancing the diffusion capacity of pesticides, breaking the interface between pesticides and water, and reducing the agglomeration force between wettable powder particles, thereby further reducing the agglomeration phenomenon of wettable powders, making different pesticides dispersed more evenly in water.

When the pressure exceeds the pressure setting value of the second one-way valve 46, the second one-way valve 46 opens to allow the mixed liquid to enter the box body 1. Through the setting of the second one-way valve 46, the wettable powder particles in the mixed liquid can be quickly dispersed in a small amount of water under the action of continuous pressure, and the mixing of the wettable powder particles and water is accelerated, so that the mixed liquid can be mixed with a large amount of water more evenly after entering the box body 1, further reducing the agglomeration of the wettable powder, and making different pesticides dispersed more evenly in the water.
