Technical Field

[0001] The utility model relates to the technical field of agricultural fertilizers, and specifically relates to an agricultural fertilizer sampler. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation; it refers to an important industrial sector in the national economy and is a sector with land resources as the production object. In agriculture, fertilizers are needed to accelerate the growth of crops. Liquid fertilizers need to be sampled and studied during the production process to improve the effect of fertilizers in promoting growth.

[0003] However, the existing agricultural fertilizer samplers have the following disadvantages:

[0004] (1) For the existing agricultural fertilizer samplers, the sampling function is relatively weak. After the sampling device finishes sampling, fertilizers will remain inside, which may cause problems affecting subsequent sampling.

[0005] (2) For the existing agricultural fertilizer samplers, the quantitative function is relatively weak. During use, due to manual operation during sampling, problems such as inaccurate sampling may occur. Content of the Utility Model
