Description

Technical Field

[0001] The utility model relates to the field of fertilization equipment machinery, and specifically refers to a fertilization equipment and a soil covering machine based on the fertilization equipment. Background Art

[0002] Soil fertilization refers to the agricultural technical measure of applying fertilizers to the soil to provide nutrients required by plants (such as tobacco, wheat, corn, sweet potatoes, etc.) and maintain and improve soil fertility. The main purposes of soil fertilization are to increase crop yields, improve crop quality, fertilize the soil, and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to maintain the sustainable development of agriculture.

[0003] The traditional soil fertilization method generally mainly adopts manual fertilization. The fertilization uniformity is not ideal and the manual physical consumption is large. To solve the problems of fertilization uniformity and the labor intensity of farmers, the inventor previously applied for a Chinese patent with the name: A fertilization equipment and a soil covering machine with more uniform fertilization, patent number: ZL202320345449.6, authorization announcement date: October 22, 2024. It discloses that "the fertilization equipment includes a storage device for temporarily storing fertilizers, a feeding device located below the storage device and used for quantitatively fertilizing the soil, and a quantitative fertilization device for quantitatively discharging the fertilizers in the storage device into the feeding device". This fertilization equipment makes the fertilization more uniform. The fertilizers (such as granular fertilizers or powder fertilizers) in the storage device are quantitatively discharged into the feeding device for fertilization operations through the rotation of the distributor in the quantitative fertilization device to discharge the fertilizers in multiple quantitative grooves on its outer peripheral surface, making the fertilization more uniform. The above fertilization equipment can solve the problem of uniform fertilization of a single fertilizer, but there are still some deficiencies. When granular fertilizers (such as potassium sulfate fertilizer) and powder fertilizers (such as magnesium fertilizer) are applied simultaneously, only the granular fertilizers and powder fertilizers can be mixed and poured into a feeding hopper of the storage device for mixed feeding. The granular fertilizers and powder fertilizers form a mixed fertilizer, but such a mixed feeding method is not ideal. When the soil covering machine is walking during fertilization, due to the influence of vibration and bumps, the granular fertilizers and powder fertilizers in the feeding hopper are prone to stratification (i.e., the lower layer is powder fertilizer and the upper layer is granular fertilizer), which makes the fertilization of the mixed fertilizer not uniform, thus affecting the fertilization effect of the mixed fertilizer. Summary of the Utility Model

[0004] The utility model provides a fertilization equipment and a soil covering machine based on the fertilization equipment, aiming to mainly overcome the shortcomings that the existing mixed feeding method is not ideal, the granular fertilizers and powder fertilizers in the feeding hopper are prone to stratification, which makes the fertilization of the mixed fertilizer not uniform, thus affecting the fertilization effect of the mixed fertilizer, etc.

When the soil covering machine is walking during fertilization, there will be no problem of stratification (i.e., the powder fertilizer is at the lower layer and the granular fertilizer is at the upper layer) of the granular fertilizer and the powder fertilizer in the discharging hopper 21 of the fertilizer discharging device 2.

[0025] Referring to the attached Figure 2 and Figure 3The storage device 1 includes a storage container 11 placed on top of the fertilizer feeding device 2 and a container cover 12 covering the top opening of the storage container 11.
