an operating rod 33 is installed on one side of the operating block 31, which is located on the pretension spring 32, the operating rod 33 is a telescopic rod, one end of an operating rope I34 is connected to the end of the operating rod 33, and the other end of the operating rope I34 is connected to the outer circumferential surface of the end of the counterclockwise blade operating rod 22. The adjusting device input port I29 is arranged on the side surface of the blade adjusting device I13 and corresponds to the chamber where the operating spring 30 is located;
the blade adjusting device II14 and the blade adjusting device I13 are consistent in internal structure, and are also provided with an operation rope II36 and an adjusting device input port II35, the operation rope II36 is connected with the outer circumferential surface of the end part of the clockwise blade operating rod 24, and the adjusting device input port II35 corresponds to a chamber where an operating spring of the blade adjusting device II14 is located;
the regulating device input port I29 is connected with a pressure regulating pipe II8, and the regulating device input port II35 is connected with a pressure regulating pipe I7. The pressure regulating pipe I7 and the pressure regulating pipe II8 are directly connected to the circumferential surface of the mixing device outer cover 37, two ends of the mixing device outer cover 37 are respectively matched with the output end 3 and the input end 10, and an input port I9 and an input port II38 are radially arranged on the mixing device outer cover 37.
The working principle is as follows: before irrigation water and fertilizer are mixed, no fluid enters the input port I9 and the input port II38, the pre-tightening spring 32 and the operating spring 30 in the blade adjusting device I13 are both in an extended state to provide pre-tightening force for the operating rope, and the operating block 31 connected with the pre-tightening spring 32 is in a static state; the operating spring 30 and the pre-tightening spring 32 are in an extended state, so that the operating block 31 provides a certain tension to the operating rod 33, and the operating rod 33 has a certain tension to make the operating rope I34 have a certain tension, so that the counterclockwise blade operating rod 22 connected with the operating rope I34 is driven to rotate in the circumferential direction. Similarly, the pretension spring 32 in the vane adjusting device II14 is in a longer extension state, and the same principle drives the operation rope II36 to have a certain tension, so as to drive the clockwise vane operating lever 24 connected with the operation rope II36 to rotate in the circumferential direction.
Since the vane adjusting device I13 and the vane adjusting device II14 are respectively installed at both sides of the counterclockwise vane operating lever 22 and the clockwise vane operating lever 24, the pulling force provided by the operating rope I34 to the counterclockwise vane operating lever 22 is opposite to the pulling force provided by the operating rope II36 to the clockwise vane operating lever 24, so that the clockwise vane operating lever 24 and the counterclockwise vane operating lever 22 rotate in opposite directions in the circumferential direction, and the clockwise mixing vane 6 and the counterclockwise mixing vane 5 installed on the clockwise vane operating lever 24 and the counterclockwise vane operating lever 22 are driven to rotate in the circumferential direction, so that the included angle between two adjacent vanes becomes larger and smaller. Because the counterclockwise blade operating lever 22 and the clockwise blade operating lever 24 are engaged, the clockwise blade operating lever 24 rotates inside the counterclockwise blade operating lever 22, and the clockwise blade operating slot 19 is formed on the outer circumferential surface of the counterclockwise blade operating lever 22, and during the clockwise blade operating lever 24 rotates in the opposite direction to the counterclockwise blade operating lever 22, the clockwise blade boss on the clockwise blade operating lever moves to the edge of the clockwise blade operating slot 19, and the relative movement of the clockwise blade operating lever 24 and the counterclockwise blade operating lever 22 stops, so that the relative movement of the counterclockwise mixing blade 5 and the clockwise mixing blade 6 thereon stops.
In practical application, at liquid manure mixing process, irrigation water and fertile liquid enter input port I9 and input port II38 respectively, get into inside the mixed rectification voltage regulator device of developments liquid manure, because anticlockwise mixing blade 5 has the effect of reposition of redundant personnel, make the inside fertile liquid of entering mixing arrangement and irrigation water reposition of redundant personnel, through the mixed liquid of reposition of redundant personnel when getting into next adjacent clockwise mixing blade 6, further mix has been carried out, further reposition of redundant personnel is further divided into two parts with mixed liquid simultaneously. The latter process of mixing the liquid split and mixing is still in this way;
because the irrigation water and the fertilizer liquid are input and mixed and divided by the anticlockwise mixing blade 5 and the clockwise mixing blade 6, the whole mixing cavity is fully filled with the mixed liquid of the irrigation water and the fertilizer liquid, the relative static states of the original anticlockwise mixing blade 5 and the clockwise mixing blade 6 are out of balance, so that the mixed liquid of the irrigation water and the fertilizer liquid passes through the pressure regulating pipe I7 and the pressure regulating pipe II8 and further respectively enters the blade adjusting device I13 and the blade adjusting device II14, the internal pressure of the operating spring 30 in the blade adjusting device I13 and the blade adjusting device II14 is increased, the operating spring 30 continues to extend, the length of the operating rod 33 connected with the operating block 31 is changed from the extending state to the natural state, the tensile force of the operating rope I34 connected with the operating rod is reduced, and due to the fluid action in the mixing cavity, so that the counterclockwise mixing blades 5 and the clockwise mixing blades 6 are relatively moved in the circumferential direction.
Under the velocity of flow pressure change circumstances, the pressure size of mixing chamber inside also can be through pressure regulating pipe I7 and pressure regulating pipe II8 to the inside transmission of blade adjusting device I13 and blade adjusting device II14, thereby make blade adjusting device I13 and blade adjusting device II14 to the pulling force dynamic change of anticlockwise hybrid blade 5 and the installation axle of clockwise hybrid blade 6, thereby make irrigation water and fertilizer liquid in mixing process, can adapt to the dynamic change of pressure and velocity of flow, adjust the relative position between anticlockwise hybrid blade 5 and the clockwise hybrid blade 6, make the mixed liquid that flows through two kinds of blades pass through the reposition of redundant personnel in proper order, the dynamic change of compression and inflation, thereby improve the mixed effect, keep the balanced purpose of pressure, thereby improve the degree of consistency of irrigation of water and fertilizer integration.

b. the split mixed liquid is further mixed when entering the next adjacent clockwise mixing blade 6 or counterclockwise mixing blade 5, and the mixed liquid is further split into two parts by further splitting; the mixture of irrigation water and fertilizer liquid is filled in the whole mixing cavity through the repeated mixing and flow distribution of the plurality of anticlockwise mixing blades 5 and the clockwise mixing blades 6;
c. after the inside of the whole mixing cavity is filled with mixed liquid of irrigation water and fertilizer liquid, the relative static states of the original anticlockwise mixing blade 5 and the original clockwise mixing blade 6 are out of balance, the mixed liquid respectively enters the corresponding blade adjusting devices through two pressure regulating pipes, and the fluid action pressure in the mixing cavity is fed back to the blade adjusting devices, so that the anticlockwise mixing blade 5 and the clockwise mixing blade 6 move relatively in the circumferential direction;
