Disk sprinkling fertilization measuring device

Abstract

The present invention discloses a detecting device for spreading fertilization of a disc comprising a displacement controller used for control the pulse signal number and frequency; a three-dimensional displacement platform; a stepping motor which is fixed on the three-dimensional displacement platform and electrically connected with the displacement controller and used for controlling a step angle; a fertilizer box fixed on the three-dimensional displacement platform; a transducer used for controlling the frequency of an output power; a asynchronous motor electrically connected with the transducer and used for controlling timing; a fertilization disc connected with the asynchronous motor; a fertilization blade fixed on the fertilization disc. The device and realize the disc spreading fertilization operation of different fertilization port positions, different fertilization port sizes, different disc rotation speeds, different fertilization disc heights, different fertilization blade inclinations and different fertilization blade groups; the structure is rational and the setting of the function parameters is simple and fast; the present invention can implement assessment on the operation effect of variable fertilization fast and conveniently; in this way, accurate fertilization can be ensured.

Description

technical field [0001] The invention relates to a measuring device for disc spreading and fertilization, in particular to a measuring device for spreading and fertilizing which can conveniently and accurately adjust factors affecting fertilization. Background technique [0002] Fertilization is one of the important measures to increase agricultural production. Extensive application of fertilizers has greatly increased the material and energy cycle content of the agricultural production system, and has played a positive role in the sustainable and stable growth of agricultural production. Experimental studies have shown that when fertilizers are applied properly, the effect of increasing production accounts for about one-third of the total grain output. If the nutrients necessary for various crops cannot be supplied in a balanced manner according to soil conditions and crop demand laws, fertilizer efficiency will be reduced, economic benefits will be reduced, and the impact wi...

Problems solved by technology

Experimental studies have shown that when fertilizers are applied properly, the effect of increasing production accounts for about one-third of the total grain output. If the nutrients necessary for various crops cannot be supplied in a balanced manner according to soil conditions and crop demand laws, fertilizer efficiency will be reduced, economic benefits will be reduced, and the impact will be reduced. The sustainable and stable development of agricultural production and environmental quality, so precision agriculture has become a trend in agricultural development

[0003] With the development of precision agriculture and the increasing maturity of precision fertilization theory, variable fertilization technology has gradually replaced traditional fertilization in countries with developed precision agriculture such as the United States, and has become the mainstream technology of farmland fertilization. At present, the theory of precision fertilization in my country is also gradually improving. However, there are still deficiencies in the development of precision fertilization machinery products: most of the existing fertilizer spreaders in my country are traditional fertilization machinery with a small width. Due to the small width and low efficiency of the machines, they are not suitable for large-scale farms in my country to carry out large-scale variable operations; In order to carry out large-scale variable operations on large farms, a disc fertilizer applicator was introduced. However, due to the large number of parameters affecting the performance of the disc fertilizer applicator and the large amount of testing, the cost of introducing existing foreign fertilizer applicators is too high. Therefore, the domestic disc-type fertilizer applicator gave up the previous test of the fertilizer applicator, and directly carried out the design and processing, so that the produced disc-type fertilizer was useless to achieve the ideal operating performance, which directly affected the function and effect of the variable fertilization technology.
