The device for irrigation and fertilization of crops, during use, puts water and liquid fertilizer in the material box, and then starts the motor. When the motor works, the right shaft and roller are driven to rotate through the bevel gear, and then the bottom plate moves as a whole.

The circular plate 61 is connected to the transmission shaft 43 through a fixing device, so its rotation can drive the movement of other components in the system. The slider 63 is installed in the mounting groove B62 inside the circular plate 61. As the circular plate 61 rotates, under the action of centrifugal force, the slider 63 begins to slide along the inner wall of the mounting groove B62, and the moving direction and speed of the slider 63 are proportional to the rotation speed and centrifugal force of the circular plate 61. Therefore, the moving distance of the slider 63 can accurately control the pressure change in the hydraulic system. As the slider 63 slides along the mounting groove B62, it pushes the hydraulic rod A65 to slide inside the hydraulic chamber A64. The sliding of the hydraulic rod A65 not only changes the pressure distribution of the liquid in the hydraulic chamber A64, but also affects the action of the subsequent hydraulic components. When the hydraulic rod A65 pushes the hydraulic oil or other medium in the hydraulic chamber A64, the hydraulic pressure will be transmitted to the hydraulic rod B66. The hydraulic rod B66 is connected to the arc plate 611. The arc plate 611 will be displaced under the action of the hydraulic chamber A64. After being squeezed by the hydraulic rod B66, the arc plate 611 will move downward, further pushing the hydraulic rod C68 into the hydraulic chamber B67. The sliding of the hydraulic rod C68 will push the liquid in the hydraulic chamber B67 to the ports at both ends, so that the hydraulic rod D69 connected to the two ends of the hydraulic chamber B67 slides outward. The sliding of the hydraulic rod D69 is a key step for the system to achieve the clamping operation. The hydraulic rod D69 is mechanically transmitted or directly connected to the clamping plate 610, so that the clamping plate 610 slides outward and finally contacts the outer wall of the fertilizer mixing tank 3 to complete the fixing action. The clamping plate 610 is the final execution component of the entire clamping system. When the hydraulic rod D69 slides, the clamping plate 610 will slide outward and finally contact the outer wall of the fertilizer mixing tank 3, thereby firmly fixing the fertilizer mixing tank 3.
