The thesis takes the research of the working accuracy and the influencing factors of variable rate sprayer system used in agriculture.

Experimental study on variable-rate spraying equipment response capability;

The response time was obtained by making the variable-rate spraying experiments, the spraying capabilities were also studied.

Characteristics and comparison of pressure-based variable spray

At the foundation of summarized the domestic and foreign related research, this article studied an inter-variable spray control system which is based on the machine vision, also designed the software and hardware test platform for block spray control, determined the image processing algorithms and adjust various algorithms under the simulation in the laboratory.

To verify the accuracy of the algorithm about real-time collection,processing image and to determine the matching relationship between implementation modules of the system and other modules,after the paper analyzes the parallel interface resources and the access methods,it introduces a design of the software and hardware based on the parallel interface to control variable spray operation.

Study on pre-mixed air spraying system;

The double fluid fume spraying system was used in reconstruction of the cooling system of 1000 m3 blast furnace gas of Maanshan Iron & Steel Co.

This paper proposes several methods and measures of the improvement of spraying system in Model EBZ- 120 tunneller, which used in most coal mines throughout our country, according to the questions arising in the application of it.

Failures tree and reliability analysis of roadheader spray system;

Improvement on outer spray system of EBH-120 Roadheader;

This paper introduces the dedusting principle of the spray system of roadheader, and the problem existed in the spray system of EBZ-160 Roadheader, brought forward the suggestion on the technological improvement on the spray system of EBZ-160 Roadheader to improve the dedusting effect to meet the requirement of modernistic coal mine.
