step three: when the first threaded rod (403) drives the first sliding block (411) to translate, the first threaded rod (403) drives two flywheels (508) to rotate through a belt (502), the flywheels (508) drive the second threaded rod (505) to rotate synchronously, the second threaded rod (505) drives a traction block (500) to translate synchronously with the second sliding block (421) on two sliding rails (507), the traction block (500) drives the discharge plate (501) to translate synchronously, so that the second sliding block (421) and the discharge plate (501) respectively drive a telescopic block (431), a telescopic shaft (432), a partition plate (433) and a return spring (434) to move synchronously, when the inclined plane end of the telescopic block (431) is abutted against the top of the corresponding resistance block (435), the telescopic block (431) slides towards the inside of the sliding hole (4211) and drives the partition plate (433) to move through the telescopic shaft (432), at the moment, the return spring (434) is in a compression state, the partition plate (433) slides in a blocking hole (5011) of the discharge plate (501), until the discharge hole (4330) on the clapboard (433) is communicated with the column hole (5010) in the discharge plate (501), so that the fertilizer on the top of the clapboard (433) falls into the lower bottom pipe (520) through the column hole (5010) and the square hole (5000), the fertilizer falls into the fertilizing tank (521) along the lower bottom pipe (520), and falls into a fertilizing land from the fertilizing hole (10) through the fertilizing tank (521), after the telescopic block (431) passes through a block (435), the telescopic block (431) can be immediately reset due to the action of the reset spring (434), and the column hole (5010) is cut off;

step four: when the traction block (500) and the discharge plate (501) move synchronously, the discharge plate (501) drives the discharge pipe (511) to move, the discharge pipe (511) drives the discharge hopper (510) and the four support columns (514) to synchronously slide in the convex grooves (5120) of the two slide bars (512), the traction block (500) drives the lower bottom pipe (520) to move, the lower bottom pipe (520) drives the slide bars (522) to slide on the tops of the two trapezoidal plates (523), and therefore the fertilization tank (521) is driven to synchronously move.
