A MIXER/FEEDER APPARATUS AND A DEVICE FOR MONITORING OPERATION OF THE MIXER/FEEDER APPARATUS

摘要

A mixer/feeder wagon (1) for mixing and dispensing batches of animal feed comprises a device (50) for monitoring operation of the mixer/feeder wagon (1) and for determining instants during a mixing cycle during which ingredients of the animal feed are to be loaded into the mixer/feeder wagon (1). The mixer/feeder wagon (1) comprises a mixing compartment (14) within which a paddle mixer (17) is rotatable for mixing the ingredients of the batch of animal feed therein. Load sensors (9) produce signals indicative of the current weight of the ingredients in the mixing compartment (14) which are read by a microprocessor (55) of the device (50). A proximity sensor (38) counts the number of revolutions of the paddle mixer 17. Particulars of the ingredients of the batch of animal feed together with the weights of the respective ingredients are stored in a RAM (56) in the device (50) as well as the instants during a mixing cycle at which the respective ingredients are to be loaded into the mixing compartment (14) based on the count of revolutions of the paddle mixer (17) from the commencement of the mixing cycle. The microprocessor (55) in response to signals from the proximity sensor (38) outputs a signal to activate a siren (67) to indicate when the next ingredient is to be loaded into the mixing compartment (14). The identities of the respective ingredients as they are to be loaded into the mixing compartment (14) are displayed on a visual display screen (54) together with the weights thereof.
