Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilizing equipment, in particular to a punching fertilizing equipment for crop planting. BACKGROUND

[0002] When fertilizing on the surface, the fertilizer is exposed to the surface layer of the soil, which is easy to be washed away by rain, blown away by wind or decomposed by sunlight, resulting in a large amount of nutrient loss. Punching fertilization can directly send the fertilizer into the deep layer of the soil, reducing the loss through the wrapping of soil particles, saving fertilizer costs and reducing environmental pollution. In general, punching fertilization is performed on soft soil.

[0003] The patent with the patent announcement number CN222322194U relates to a punching fertilizing equipment for crop planting, which includes a stand column. A sliding groove is formed on the outer surface of the stand column. A sliding block is movably clamped inside the sliding groove. A construction mechanism for punching fertilization and seeding is arranged on the outer surface of the sliding block. The construction mechanism includes a seed storage bin, a fertilizer storage bin, a seeding roller, a fertilizing roller and an insertion pipe. The seed storage bin is fixedly arranged on one side of the surface of the sliding block. The fertilizer storage bin is fixedly arranged on the side of the surface of the sliding block away from the seed storage bin. The seeding roller is movably arranged inside the seed storage bin through a rotating shaft. The fertilizing roller is movably arranged inside the fertilizer storage bin through a rotating shaft. The seed storage bin and the fertilizer storage bin are fixedly provided with the insertion pipe at the lower end. The insertion pipe can be inserted up and down once to complete the hole opening, seeding and fertilization processes, which can greatly improve the seeding and fertilization efficiency.

[0004] In the above-mentioned patent, the insertion pipe can be inserted up and down once to complete the hole opening, seeding and fertilization processes, which can greatly improve the seeding and fertilization efficiency. However, the fertilizer has strong hygroscopicity and is easy to absorb moisture in the air or humidity in the soil, which will cause differences in fertilization amount due to the residue on the inner wall of the material distribution hole. In addition, the punching depth directly affects the burial position of the fertilizer. If the punching depth is different at different positions, even if the fertilizer amount is the same, the difference in the distribution depth of the fertilizer in the soil will affect the crop absorption. Therefore, it is necessary to design a punching fertilizing equipment for crop planting, which has strong practicability and prevents the fertilizer from being left on the inner wall of the material distribution hole.
