DETAILED DESCRIPTION

[0019] Please refer to Figures 1 to 6 ;

[0020] This embodiment provides a herbicide concentration adjustment device, referring to Figure 1 and Figure 2, comprising a mixing drum 1, at least three supporting feet 101 are provided at the bottom of the mixing drum 1, a stirring assembly 2 extending into the mixing drum 1 is provided at the top of the mixing drum 1, at least one feed pipe 104 is provided at the top of the mixing drum 1, a discharge pipe 106 is provided at the bottom of the mixing drum 1, a water inlet pipe 105 is provided in the middle of the feed pipe 104, and electric flow valves 3 are provided at the ends of the water inlet pipe 105 and the discharge pipe 106;

[0021] In a specific implementation, the top of the feed pipe 104 is connected to the discharge port of the herbicide quantitative injection device;

[0022] The herbicide quantitative injection device is an existing device;

[0023] Concentration formula: C = m / V;

[0024] The specified concentration can be formulated by controlling the amount of herbicide injected and the amount of water injected;

[0025] When the concentration is adjusted, a fixed amount of herbicide is injected from the feed pipe 104, and the amount of injected water is monitored by the electric flow valve 3. By injecting a fixed amount of herbicide and a fixed amount of water and stirring and mixing, a herbicide solution of a specified concentration can be obtained.

[0026] For further reference, Figure 2 A vertically upward buffer tube 102 is provided on the top of the mixing drum 1, and a buffer tube 103 that can move up and down is provided inside the buffer tube 102. The outer wall bottom and top of the buffer tube 103 are provided with an outwardly convex annular structure, and the bottom outer wall of the buffer tube 103 and the inner wall of the buffer tube 102 form a piston structure. A limiting ring is provided on the top of the inner wall of the buffer tube 102, and the annular structure is clamped with the limiting ring;

[0027] In a specific implementation, when the herbicide raw material and water are mixed and stirred, bubbles are generated inside the mixing drum 1, and the bubbles will fill the space in the area where the herbicide is easily absorbed. Under the push of the bubbles, the buffer drum 103 moves upward inside the buffer tube 102. When bubbles are generated, they can be buffered by the inside of the buffer drum 103 and the buffer tube 102, which can effectively prevent the bubbles from overflowing and the herbicide from leaking.

[0028] For further reference, Figure 3 The stirring assembly 2 includes a transmission shaft 201 inserted through the top of the mixing drum 1, a sealing assembly 4 is provided at the connection between the transmission shaft 201 and the mixing drum 1, a spiral stirring blade 202 is provided on the outer wall of the transmission shaft 201, a motor 203 is provided on the top of the mixing drum 1, and the output shaft of the motor 203 is connected to the transmission shaft 201;

[0029] In the specific implementation, when stirring, the output shaft of the motor 203 drives the transmission shaft 201 to rotate, so that the transmission shaft 201 drives the stirring blades 202 to stir. The stirring blades 202 are arranged in a spiral shape, so that the solution at the bottom can be stirred upward, so that the herbicide raw material and water are mixed evenly.

[0030] Furthermore, the stirring blades 202 are arranged in a mesh shape;

[0031] In a specific implementation, the stirring blades 202 can stir the solution upwards and cut the solution through the mesh structure, so that the solution is stirred evenly.

[0032] For further reference, Figure 4 The sealing assembly 4 includes a connecting ring 401 connected to the top of the mixing drum 1, the inner wall of the connecting ring 401 is provided with a C-shaped groove 411, the inner wall of the C-shaped groove 411 is provided with a C-shaped sealing ring 402, the inner wall of the C-shaped sealing ring 402 is provided with a C-shaped sliding ring 403, and the inner wall groove of the C-shaped sliding ring 403 is provided with a plurality of balls 404, and the transmission shaft 201 passes through the connecting ring 401, the C-shaped sealing ring 402, and the inner wall of the C-shaped sliding ring 403 is sealed by the C-shaped sealing ring 402;

[0033] In specific implementation, when the seal is rotated, the transmission shaft 201 rotates, so that a number of balls 404 are in the inner wall groove of the C-type sliding ring 403. The friction between the balls 404 and the inner wall of the C-type sliding ring 403 generates heat, and the heat is transferred to the C-type sealing ring 402, so that the C-type sealing ring 402 expands due to the heat, making the sealing structure at the contact surface between the C-type sealing ring 402 and the transmission shaft 201 tighter, thereby reducing the volatilization of the herbicide solution gas.
