Problems solved by technology
[0003] However, the current sieving process of granular fertilizer mainly has the following problems: the sieve hole is easy to be blocked during the sieving process of granulated fertilizer, and continuous sieving of granulated fertilizer cannot be guaranteed; Shaking, resulting in low screening efficiency of granular fertilizers; secondly, quantitative screening cannot be carried out during the screening of granular fertilizers, resulting in the amount of granular fertilizers for each screening is not constant, which affects the screening effect of granular fertilizers

The invention relates to the technical field of fertilizer preparation, and particularly relates to a multistage screening machine for fertilizer preparation. The multistage screening machine comprises an auxiliary device, supporting legs, a screening device and a feeding device. The multistage screening machine solves the problems that in the current particle fertilizer screening process, screen holes are prone to being blocked, and continuous screening of particle fertilizer cannot be guaranteed; in the vibration screening process of the particle fertilizer, multi-dimensional shaking is difficult to conduct, and consequently the screening efficiency of the particle fertilizer is low; and in the screening process of the particle fertilizer, quantitative screening cannot be conducted, consequently, the amount of the particle fertilizer screened each time is not constant, and the screening effect of the particle fertilizer is influenced. According to the multistage screening machine, the multistage screening efficiency of the particle fertilizer is improved, and the particle fertilizer is effectively prevented from blocking the screen holes.
Description
technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a multistage screening machine for fertilizer preparation. Background technique [0002] Fertilizer is a kind of substance that provides one or more necessary nutrient elements for plants, improves soil properties, and improves soil fertility level. It is one of the material bases of agricultural production; the initial stage of fertilizer preparation is mostly granular elements with uneven sizes; The prepared granular fertilizer needs to be screened through a multi-stage screening device. [0003] However, the current sieving process of granular fertilizer mainly has the following problems: the sieve hole is easy to be blocked during the sieving process of granulated fertilizer, and continuous sieving of granulated fertilizer cannot be guaranteed; Shaking causes the screening efficiency of granular fertilizer to be low; secondly, quantitative screening cannot be ...
