Movable threshing cleaning test stand

Abstract

The present invention provides a movable threshing cleaning test stand. The test stand comprises a rack, a front-end cutting table, a walking chassis positioned below the rack, as well as a threshing cylinder, a grass stirring wheel, a grass comminuting device, a cleaning mechanism, a control cabinet, a monitoring system and wireless communication device equipment which are arranged above the rack; wherein the threshing cylinder is arranged at an output end of the front-end cutting table; a cleaning chamber is arranged below the threshing cylinder; the cleaning mechanism comprises a vibrating screen and a blower which are positioned below the threshing cylinder; the grass stirring wheel is arranged between the threshing cylinder and the grass comminuting device, and is used for sending straw output by the threshing cylinder to the grass comminuting device; the control cabinet is connected with a computer terminal through the wireless communication equipment; the monitoring system is connected with the control cabinet; and the monitoring system comprises a torque measuring mechanism for the threshing cylinder and the grass comminuting device, and a wind field measuring system disposed in the cleaning chamber. The test stand provided by the present invention is novel in structure design, and compared with a conventional test device, the test stand has better test operability.

Description

technical field [0001] The invention relates to an agricultural equipment, which belongs to the field of machinery, in particular to a mobile threshing and cleaning test bench which can be operated in the field. Background technique [0002] At present, although rice, wheat, oil and other food crops are widely planted in China, the level of mechanized harvesting has not been high. Therefore, the research and development of harvesters with better harvesting effects is particularly important for promoting the development of modern agriculture. For the design of the harvester, the empirical design has been adopted in the past, the design is relatively extensive, and there is no specific parameter research. Some researchers have done laboratory simulation experiments on the harvesting performance of combine harvesters, and obtained some data, which have certain guiding significance for the design of combine harvesters. However, the test crops used in the laboratory are differen...
