The working method of the invention is as follows:
the working method of the drip irrigation fertilizer dilution system comprises the following steps:
the water jet flow ejected from the water jet flow outlet end 78.1 of the water supply pipe 2 with inconstant water pressure enables the circular-disk-shaped rotational flow diluting bin 9 to form a circular flow, the circular flow formed in the circular-disk-shaped rotational flow diluting bin 9 can drive each hydraulic blade 47 to rotate along the axis of the central blade seat 37, and the larger the flow rate of the water jet flow ejected from the water jet flow outlet end 78.1 is, the larger the rotation speed of the central blade seat 37 along the axis of the central blade seat 37 is; the stirring column 18 synchronously rotates along the axis along with the central blade seat 37 under the linkage of the liquid transfer shaft 6, the rotation of the stirring column 18 along the liquid transfer shaft 6 enables the concentrated fertilizer dissolving bin 16 to form a continuous rotation disturbance state, further the bottom of the concentrated fertilizer dissolving bin 16 is effectively prevented from forming deposition in an accumulation state, the stirring effect is also achieved, and the concentrated liquid fertilizer in the concentrated fertilizer dissolving bin 16 is stirred more uniformly;
because the mass of the left half of the cylindrical valve core 24 is greater than the mass of the right half of the cylindrical valve core 24, the center of gravity of the cylindrical valve core 24 is shifted to the left; when the stirring column 18 rotates along the axis of the liquid transfer shaft 6, the whole cylindrical valve core 24 is equivalently subjected to a left centrifugal force, so that the whole cylindrical valve core 24 overcomes the elasticity of the spring 29 to move leftwards under the action of the centrifugal force, the left displacement of the cylindrical valve core 24 enables the flow control ring groove 30 to displace leftwards until the flow control ring groove 30 mutually communicates the liquid inlet hole 17 with the concentrated fertilizer liquid transfer channel 20, and the liquid in the concentrated fertilizer dissolving bin 16 flows downwards into the concentrated fertilizer liquid transfer channel 20 through the liquid inlet hole 17 and the flow control ring groove 30; the disc-shaped rotational flow diluting bin 9 is communicated with the fertilizer diluent storage bin 8 through the diluent overflow port 61, so that the water pressure of the disc-shaped rotational flow diluting bin 9 is consistent with that of the fertilizer diluent storage bin 8, the concentrated fertilizer dissolving bin 16 is higher than the fertilizer diluent storage bin 8, the gravitational potential energy in the concentrated fertilizer dissolving bin 16 is larger than that in the fertilizer diluent storage bin 8, and therefore the concentrated fertilizer liquid is smoothly guided out to the edge of the circular outline in the disc-shaped rotational flow diluting bin 9 by the concentrated fertilizer liquid guide outlet 32 of the liquid guide channel 35 and is rapidly and uniformly mixed and diluted with water in the disc-shaped rotational flow diluting bin 9 under the driving of rotational flow;
the greater the flow rate of the water jet emitted from the water jet outlet end 78.1, the greater the speed of rotation of the central vane support 37 along its own axis; therefore, the larger the rotating speed of the stirring column 18 is, the larger the centrifugal force applied to the cylindrical valve core 24 is, the centrifugal force applied to the cylindrical valve core 24 overcomes the elastic force of the spring 29 to do centrifugal motion, the larger the centrifugal force applied to the cylindrical valve core 24 is, the larger the degree of compression of the spring 29 is, so that the displacement of the cylindrical valve core 24 which makes centrifugal movement to the left is also larger, because the groove depths of the plurality of flow control ring grooves 30 gradually increase from left to right, the larger the displacement of the cylindrical valve core 24 doing centrifugal motion leftward, the larger the groove depth, the larger the flow control ring groove 30 will make the liquid inlet hole 17 and the concentrated fertilizer liquid transferring channel 20 communicate with each other, increasing the flow rate that the liquid in the concentrated fertilizer dissolving bin 16 flows downwards into the concentrated fertilizer liquid transferring channel 20 through the liquid inlet hole 17 via the flow control ring groove 30, thereby leading the concentrated fertilizer liquid outlet 32 of the liquid guide channel 35 to have larger flow rate in the disc-shaped rotational flow diluting bin 9; the comprehensive effect is as follows: the strength of the water jet ejected from the water jet outlet end 78.1 is positively correlated with the flow of the concentrated fertilizer from the concentrated fertilizer liquid outlet 32 to the disc-shaped rotational flow diluting bin 9, so that the stable diluting proportion is maintained even if the water pressure of the water supply pipe 2 is not constant;
under the hydraulic action of the water supply pipe 2, the diluent diluted in a rotational flow state at the edge of the outline of the disc-shaped rotational flow diluting bin 9 gradually flows in a centripetal direction close to the axis of the disc-shaped rotational flow diluting bin 9 and is in a rotational flow state all the time while performing centripetal motion, so that the effect of continuous dilution is achieved, and finally the completely diluted diluent in the disc-shaped rotational flow diluting bin 9 continuously overflows into the fertilizer diluent storage bin 8 through a diluent overflow outlet 61 at the axis of the disc-shaped rotational flow diluting bin 9;
because the fertilizer diluent storage bin 8 is higher than the ground, the diluted liquid fertilizer diluent in the fertilizer diluent storage bin 8 forms certain gravitational potential energy relative to the ground, the liquid in the fertilizer diluent storage bin 8 flows into the main drip irrigation pipe 3 under the action of gravity, then the main drip irrigation pipe 3 divides the liquid fertilizer diluent into branch pipes, and finally the liquid fertilizer diluent is dripped into a preset irrigation area through drip irrigation drippers on the branch pipes; since the height of the fertilizer diluent storage bin 8 is constant, the water pressure in each branch pipe is relatively constant, thereby achieving a stable drip irrigation rate.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
