Description

Technical Field

[0001] The invention relates to the field of fertilizer applicators, in particular to a fertilizer applicator for low-humidity materials. Background Art

[0002] Traditional fertilization methods consume physical energy and are time-consuming. In addition, the utilization rate of chemical fertilizers is low, which can easily cause soil compaction. In recent years, fertilizer applicators have undergone many years of improvement and are small in size, light in weight, and easy to operate. Using fertilizer applicators to apply fertilizers can reduce farmers' labor intensity, improve the utilization rate of chemical fertilizers, and achieve good results in saving fertilizer, labor, time, and money.

[0003] The fertilizer applicator can directly apply fertilizer to the soil below the roots of crops, and can adjust the amount of fertilizer and the depth of fertilizer application according to the different needs of crops. Using a fertilizer applicator can save more than half of the fertilizer compared to farmers' fertilization methods, increase the fertilization speed by about 4 times, and increase the yield by about 15%.

[0004] Normally, high-humidity fertilizers (humidity 70%-90%) can be applied by machine, and dry fertilizers (humidity 10%-20%) can be applied with normal fertilizer spreaders. Low-humidity fertilizers (humidity 30%-45%) are more difficult to apply, have poor fluidity, and are not easy to push.

[0005] Therefore, it is necessary to design a new technical solution. Summary of the invention
