Description
Protective forest plantations, shelter belts and plantings along the highways of Central - Black Earth region and southern Russia are badly damaged, and in some areas destroyed. Therefore, they can not perform their functions and require major reconstruction or restoration. The most resistant and applicable trees and shrubs to create protective forest plantings are: maple, ash, elm species and three-thorned acacia, honey-locust, white and yellow acacia, and other legumes breeds with high drought tolerance, disease resistance, technogenic pollution and pest damage. For the creation and restoration of protective forest plantations we require seeds of these species containing pericarp. In Voronezh State Forestry Academy we have carried out a scientific research for creation of a machine for extracting seeds from the legumes. Analysis of the results of scientific research of prototyping machines showed that they were made without considered technological and mechanical properties of the legumes theoretical researches workflow machines for extracting seeds from the legumes and scientific basis of design parameters and operating modes. In this article we have a presentation of the experimental sample of the machine for extracting seeds from the legumes and theoretical investigation of the workflow in the batch hopper. According to the results of the study, we have obtained a mathematical expression, which allows you to define the parameters and modes of operation of a brush-grater device

Description
This article discusses the results of theoretical researches of development of the regimes of a veneering of wood based materials with valuable wood veneer. In the conditions of a growing demand for the furniture veneered with a natural wood veneer there is a problem with using thin wood veneer and development regimes of a veneering. In work are listed the main factors which exert impact on glue seepage during veneering. Two factors are considered: thickness of a wood veneer and amount of the applied glue as the main and defining seepage of glue and durability of the received glue connection. By results of researches conclusions are given: thickness of the applied wood veneer closely connected with the veneering regime, changing parameters of which it is possible to reduce wood veneer thickness without deterioration of a surface to the minimum values depending on breed of wood; the offered formula for definition of a consumption of glue at a veneering allows to define theoretically conditions of receiving strong pasting and excluding seepage of glue
