Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ginned cotton production detection equipment, and particularly relates to a multifunctional vehicle-mounted device for detecting ginned cotton temperature and humidity. BACKGROUND

[0002] At present, with the popularization and application of mechanical picking cotton technology, the number and technology of cotton picking machines are rapidly increasing, so that the ginned cotton harvesting period is greatly shortened, causing a large amount of ginned cotton to be accumulated in cotton processing plants, and the ginned cotton generally exists in the form of round modules in the yard. Due to the old equipment or quality reasons of the processing plant, the processing efficiency is low, thereby causing the ginned cotton to be stored in the cotton processing plant for too long, and the temperature and humidity of the ginned cotton pile and the moisture regain value change greatly due to weather and other reasons. Cotton fibers will generate heat due to various factors, mainly including moisture absorption and heat release, fermentation and heat release, and oxidation and heat release, etc., which causes a large number of microorganisms to breed, causing the quality of cotton to change and even mildewing, which not only affects the quality of cotton, but also causes economic losses of the cotton ginning factory. Domestic research on the detection of ginned cotton pile temperature and humidity has been carried out for a long time, but the actual implementation and application are still relatively rare. Especially, the integrated detection of ginned cotton round module temperature and humidity and moisture regain rate and the removal of the outer packaging of the ginned cotton round module are still a blank.

[0003] Nowadays, it is very troublesome and has great safety hazards for many cotton ginning factories to remove the outer packaging of the ginned cotton round module, and the specific process is as follows: the driver uses a forklift truck with a three-pronged head to send the round cotton module to the vicinity of the feeding machine, a worker uses a craft knife to cut the outer packaging of the round module near the feeding pit, another worker removes and recycles the cut outer packaging of the cotton module, and finally another forklift truck sends the ginned cotton into the feeding pit. The grab of the two forklift trucks is not the same, this process is very complicated, and the simultaneous operation of the person and the forklift has high risk. This link needs to consume high cost, and the processing plant urgently needs to improve the current cotton processing detection link. SUMMARY
