Description

Technical Field

[0001] The invention relates to the technical field of agricultural drip irrigation, and more specifically to a drip irrigation device with water and fertilizer regulation functions. Background Art

[0002] A drip irrigation device with water and fertilizer regulation function is an intelligent device that combines modern agricultural irrigation and fertilization technology; it is mainly used to accurately provide water and nutrients to crops, and through a series of sensors, controllers and delivery components, it delivers water and fertilizer to the roots of crops in the best proportion and amount to meet the growth needs of crops.

[0003] In drip irrigation devices with water and fertilizer regulation functions, the stirring structure plays a vital role; the paddle-type stirring paddle has a simple structure, and multiple flat blades are similar to fan blades. When rotating, it generates horizontal shear force, which promotes the fertilizer solution to form circular convection and quickly disperses the fertilizer particles. It is suitable for fertilizer solutions with good fluidity; the anchor-type stirring paddle is shaped like an anchor and fits the tank wall, which can prevent fertilizer from accumulating on the tank wall and drive the surrounding solution to circulate up and down, and has a good stirring effect on fertilizer solutions containing viscous components.

[0004] At present, when a stirring structure is used in a drip irrigation device to stir granular fertilizer, the stirring structure has a relatively single function and cannot simultaneously meet the granular fertilizer crushing and stirring effects. As a result, the stirring structure needs to wait for the fertilizer to dissolve when stirring the granular fertilizer, which results in a long time and great limitations. In view of this, we propose a drip irrigation device with water and fertilizer regulation function. Summary of the invention

[0039] Working principle: This embodiment provides a drip irrigation device with water and fertilizer regulation function. When in use, water and granular fertilizer are first put into the mixing tank 1. When the granular fertilizer is crushed, the second motor 504 works first through the external circuit mechanism.

First, the second motor 504 drives the driving gear 505 to rotate through the external circuit mechanism, and the transmission ring 502 rotates through the gear meshing transmission. A plurality of push blocks 503 slide inside the straight hole 501a and the inclined hole 502a through the insertion rods on both sides.
