[0015] 1. A soil crusher for agricultural planting, by providing a liquid storage tank and a suction box, water, fertilizer or pesticide to be sprayed after loosening the soil is added into the liquid storage tank. When the roller drives the soil crushing knife to rotate, the first transmission wheel, the second transmission wheel and the transmission belt drive the rotating rod to rotate, so that the eccentric rod drives the sliding groove to reciprocate, and at the same time, the sliding groove pulls the piston plate to reciprocate through the pull rod. When the piston plate moves toward the direction close to the rotating rod, the first one-way valve opens and the second one-way valve closes, so that the water, fertilizer or pesticide in the liquid storage tank enters the suction box through the water inlet pipe, and then the piston plate moves in the opposite direction, the first one-way valve closes, and the second one-way valve opens, so that the liquid in the suction box is transported to the guide pipe through the water outlet pipe, and then sprayed out through the nozzle to the crushed soil, so that fertilizer or pesticide can be sprayed simultaneously when the soil is crushed, thereby improving farming efficiency.

[0016] 2. This agricultural soil crusher is connected to a driving device through a transmission connecting rod by setting a roller shaft, and then drives the roller shaft to rotate after being decelerated by a reducer, thereby causing a number of evenly arranged soil crushing knives to rotate and crush the soil clods, thereby ensuring the soil crushing effect and improving the reliability of use.

[0017] 3. This agricultural planting soil crusher is equipped with a scraping plate. First, the hand wheel is turned to drive the threaded support rod to rotate, and at the same time, another threaded support rod is driven to rotate synchronously through the synchronous wheel and the synchronous belt, so that the bottom of the scraper is deflected, and then the height of the bottom of the scraper is adjusted according to the depth of the crushed soil. When the soil crushing knife crushes the soil and the nozzle sprays fertilizers or pesticides, the bottom of the scraper scrapes the ground flat, so that the sprayed fertilizers or pesticides are covered by the crushed soil, preventing the fertilizers or pesticides from being exposed on the soil surface and causing ineffectiveness or causing animal poisoning.
