Liquid fertilizer applying device and method with soil turning and refilling functions

Abstract

The invention relates to the field of agricultural machinery, in particular to a liquid fertilizer applying device and method with soil turning and refilling functions. The liquid fertilizer applying device comprises a flat cart, wherein a rectangular receding groove is formed in the flat cart, the liquid fertilizer applying device further comprises a controller, a digging and filling mechanism, a stirring mechanism and a spraying mechanism, the digging and filling mechanism comprises an outer cylinder, an arc-shaped digging plate and a rotating assembly, the stirring mechanism comprises an inner cylinder and a stirring assembly, the spraying mechanism comprises a conical containing box, a conveying assembly, an extrusion assembly and a plurality of atomization nozzles, and the rotating assembly and the conveying assembly are electrically connected with the controller. According to the liquid fertilizer applying device and method with the soil turning and refilling functions, liquid fertilizer can be uniformly mixed with soil, fertilizer application is more uniform, meanwhile, dug soil can be completely conveyed into the device, residues are prevented, the improvement of the soil turning efficiency is facilitated, the dug soil can be thoroughly refined, and the soil turning effect is improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a device and method for applying liquid fertilizer with the function of turning and refilling soil. Background technique [0002] Some crops are drought-tolerant and do not require much water, so the soil will become harder due to lack of water; for some land that is too dry and the soil is hard, directly plowing and fertilizing the land will consume a lot of manpower , and the fertilization efficiency is not high, and large-scale application of irrigation pipelines requires more investment in equipment costs. If the liquid fertilizer is not sufficiently stirred and diluted, it will lead to unbalanced fertility and seriously affect the impact of crops. [0003] China's patent application number: CN202010322956.9; public date: 2020.07.10 discloses a mobile plowing and refilling agricultural fertilization device, including a horizontally arranged lifting mounting frame, and ...

AI Technical Summary

Problems solved by technology

[0006] 1. After the liquid fertilizer sprayed by the solenoid valve enters the mixing installation cylinder from the seepage plate, it will flow concentratedly to the center of the seepage plate, and cannot touch the soil at all positions inside it, resulting in uneven fertilization, resulting in soil and The mixing efficiency of liquid fertilizer is low

[0007] 2. Since the soil just dug has a certain viscosity, part of the soil will stick to the outer wall of the arc-shaped soil turning board, causing siltation, which not only affects the next excavation, but at the same time, the arc-shaped soil turning board cannot Dumps the soil dug inside it completely to the inside of the mixing sleeve, thus affecting the tillage efficiency

[0008] 3. The freshly turned soil has a certain degree of viscosity. It is impossible to thoroughly refine it by only designing the stirring column to stir the soil. Not only can the soil and liquid fertilizer not be fully mixed, which reduces the efficiency of fertilization, but also affects the effect of turning the soil.
