Method for adjusting the flow rate of a product spreader as a function of the grammes per square metre, device for implementing this method and spreader provided with this device

摘要

The invention relates to a method for regulating the flow rate of a product spreader as a function of the grammes per square metre which the layer of spread product must have per unit of surface area. It is characterised in that: - the transverse cross-section of the stream of product delivered by a transporter 1 of the product to be spread is rendered substantially constant, and - a reference value 10 for the speed of this transporter 1 is set up, then its actual speed is measured and the image 11 of this actual speed is then compared with the reference value 9 and the information 12 given to the servo-assisted control 4 is corrected. Application to the spreading equipment industry. IMAGE
