Abstract

The invention discloses a real-time quantity variable fertilizer distributor based on crop growth information and relates to the technical field of agricultural machinery. The real-time quantity variable fertilizer distributor comprises a crop growth information acquisition system, a walking system, a quantity variable fertilizer distribution system and a control communication system. The crop growth information acquisition system is arranged at the front end of the walking system through a bracket; canopy face-shaped information of crops is obtained in real time by a spectrum sensor; the information is transmitted to a vehicle-mounted control terminal arranged in the walking system through data exchanger ; a traveling speed and GPS (Global Positioning System) data information of the fertilizer distributor are monitored in real time by combining a speed sensor; a quantity variable fertilizer application decision-making system is operated through the control communication system and information is fed back to an intelligent quantity variable controller; the quantity variable fertilizer distribution system is executed and rotary speeds of a hydraulic motor and a stepping motor are regulated, and opening position and size of a fertilizer quantity regulation mechanism are controlled, so that online regulation of a fertilizer application amount is realized. According to the real-time quantity variable fertilizer distributor, a fertilizer distribution circular disc is of a shape with a warped concave spherical surface and the section of a fertilizer distribution blade is of a curve shape, so that the uniformity of fertilizer distribution is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering and relates to spectral sensing technology and variable fertilization technology, in particular to a real-time variable fertilizer spreader based on crop growth information. Background technique [0002] With the rapid increase of my country's population and the sharp decrease of arable land, the rational and scientific application of fertilizers has become a necessary measure and an urgent problem to be solved for the sustainable development of modern agriculture. As a result, the variable fertilization technology, which is an important part of modern precision agriculture, has become a modern The key content of research in the field of agricultural machinery equipment. [0003] Relying on modern advanced science and technology, variable fertilization technology involves three parts: farmland information collection and processing, soil geographic information system establishment a...
