Cotton picker fire monitoring system

Abstract

The invention discloses a cotton picker fire monitoring system. The system comprises a cotton picker main body, a cab, a cotton box, an air duct, a fire extinguishing device (containing a filter, an air pump, a one-way valve, an air vessel, an overflow valve, a pressure gauge, a fire extinguishing agent vessel and electromagnetic valves), a smoke sensor, temperature sensors and a near infrared sensor, wherein the fire extinguishing device is fixedly mounted between the cab and the cotton box on the cotton picker main body and positioned under the air duct; the smoke sensor and the temperaturesensors are mounted in the cotton box, and the near infrared sensor is mounted in the air duct. The fire extinguishing device is connected with the air duct through a pipeline; only certain treatmentneeds to be carried out on the air duct of the cotton picker, and then the preset function is easily realized. When a fire occurs, the sensors transmit signals to the corresponding electromagnetic valve, then the electromagnetic valve is started, and the fire extinguishing agent is pressed into the air duct by utilizing the pressure difference formed between the air duct and the fire extinguishingdevice and then reaches the cotton box along with wind, so that the purpose of isolating ignited cotton from unignited cotton in the cotton box is achieved, a great deal of time is gained for the cotton picker to shut down for unloading the cotton and extinguishing the fire, and the economic loss is reduced for farmers and machine owners.

Description

technical field [0001] The invention relates to the technical field of cotton picker equipment, in particular to a cotton picker fire monitoring system. Background technique [0002] Xinjiang is the main production area of ​​high-quality cotton in my country. In recent years, with the continuous improvement of the level of agricultural mechanization, mechanical cotton picking has become more and more widespread. At the same time, it has also caused new problems. Due to the climate in Xinjiang, during the process of machine picking cotton, the weather Dry and hot, the cotton picker and other parts of the cotton picker will rub against each other to generate heat, which will cause the cotton picker to catch fire, and what's more, the cotton machine will be burned, causing huge economic losses. According to incomplete statistics, in 2013 alone, 69 fires broke out in the Corps' jurisdiction, burning 80.3 tons of cotton and completely burning 4 cotton pickers, with losses exceedin...
