The incidence of respiratory symptoms caused by grain dust during harvesting was surveyed in a group of Lincolnshire farmers. A quarter complained of respiratory distress after working on combine harvesters or near grain driers and elevators, with cough, wheezing, and breathlessness, sometimes so severe as to prevent work. The airborne dust around combine harvesters contained up to 200 million ...

The aim of this paper is a comparison of the operating parameters of combine harvesters on a selected farm. The working parameters were measured and evaluated on combine harvesters of the CLAAS and CASE IH brand by different ages and different concepts of threshing. Measuring took place in the season of 2013 and 2014 (Lexion 770 in 2012 too). Working parameters in this case mean the performance...

A user friendly, computer based program has been developed to estimate the performance and cost of sugarcane combine harvesters and associated infield transport vehicles. The model was originally developed to assess the effect of various field parameters, infield cultural practices and also the number and capacity of infield transport vehicles on harvester output. A costing program was subseque...

Aim of study: Selecting a proper fan for the rice combine harvesters to get good cleaning performance when harvesting high yield rice. Area Jiangsu Province, China.Material and methods: Three potential multi-duct fans were designed, computational fluid dynamics hot wire anemometer technology utilized learn airflow pressure variation inside with perforated plates at outlet ducts as loads. Then, ...

The cleaning device is an important part of combine harvesters, as its superior or inferior performance directly affects the harvester greatly. With increasing rice yield, current single-duct declines greatly, and causes a large grain sieve loss level direct for farms. To optimize existing to meet feeding rate requirement, firstly, terminal velocity MOG (material other than grain) different var...
