Study of vegetable crop peeling by brush working head

It is set a challenge of constructing a dynamic model of the brush working head of the washing and cleaning machine in the preparation of vegetable tubers on the line of canned vegetables production. They are specified conditions of forming of an array of lint brush under the action of forces applied to it during operation. It is compiled the design scheme of interaction between the working head and the process material. Based on the prepared scheme they are determined formulas determining the forces acting on the brush working head. The physical meaning of these relations is determined. It has been established that there is an additional frictional force influencing on the working head. This force is caused by the elastic deformation and discontinuities in the organ of the working head. This force depends on the geometrical parameters, namely on the angle of inclination of the process material against the horizontal and the inclination angle of friction force between the rib and the top-side of the lint characterizing deformations and discontinuities. The resulting formulas are basic relations describing the ratio of brush working heads with cleaned vegetable tubers.
