МОДЕРНИЗАЦИЯ АППАРАТА ДЛЯ ОБМОЛОТА И ИЗМЕЛЬЧЕНИЯ ХЛЕБНОЙ МАССЫ

Abstract

One of the most time-consuming operations when harvesting agricultural crops is threshing and grinding of the grain mass, performed with the help of forager FN-1.4. This machine is widely used to move the silage mass in piles to the trailer tank. The currently used technical means do not meet the requirements for them, therefore, it became necessary to create more advanced ones - the modernization of the forager. The modernization of the forager FN - 1.4 is proposed to eliminate the main drawback: the complexity of the technical device, which is the cause of frequent breakdowns. The pneumatic channel is designed with the possibility of moving the seeded material from the cavity of the bottom to the cavity of the pipeline due to its gravity. The actual bottom in its lower part is made with the formation of a pitched board in the form of a rectangle, which is fixed at such an angle to the horizontal plane, which makes it possible to freely pass the processed material over its surface due to gravity. The window switching the cavities of the pneumatic channel, as well as the pipeline, is docked by its lower surface with the lower end of the pitched board. The value of the height of the window in the front side of the pipeline does not exceed two to three times the maximum grain size of the seeded material. The pneumatic channel includes a pitched board, as well as a casing. The pitched board is closed with a casing from the top. The cross section of the casing is a U-shaped shape, changing in height upwards from its front edge to the rear, while the shape of its front end along the cut is combined with the U-shaped element of the window in the front part of the pipeline wall, and the shape of the rear end along the cut is combined with the U-shaped element of the bottom in its cross section. The front edge of the casing is docked with the window, and its rear edge - with the cavity of the bottom.
