Оптимизация угла атаки плоского диска комбинированного рабочего органа культиватора

Оптимизация угла атаки плоского диска комбинированного рабочего органа культиватора

Abstract

Предложен пропашной культиватор, оснащенный комбинированными рабочими органами, позволяющий за один проход качественно выполнить уход за посевами с полной обработкой защитных зон возделываемых культур. Обработку междурядий выполняют пропашным культиватором, на каждой секции которого устанавливают два комбинированных рабочих органа таким образом, чтобы их плоские диски были направлены в сторону рядка растений под острым углом, а крайние кромки крыльев стрельчатых лап располагают у нижнего основания гребня почвы. При движении пропашного культиватора стрельчатые лапы рыхлят почву на требуемую глубину и подрезают сорные растения, а плоские диски сдвигают слой почвы, сходящий с крыльев стрельчатых лап, в сторону рядков растений, окучивая их и присыпая сорняки. Теоретически обоснован угол атаки плоского диска для присыпания сорных растений слоем почвы требуемой толщины. Выявлено, что угол атаки зависит радиуса плоского диска и глубины его хода в почве, исходных размеров гребня и физико-механических свойств почвы.

A row cultivator equipped with combined working tools and able to properly tend for crops in a single pass with complete treatment of crop protection zones is proposed. Inter-row tillage is performed with the row cultivator; each cultivator gang is equipped with two combined working tools in such manner that their flat disks are directed toward the crop row at an acute angle and the outer edges of V-shaped sweeps are positioned at the bottom of a soil ridge. The authors have theoretically proved the flat disk approach angle to cover the weeds with a soil layer of required thickness. It is revealed that the approach angle depends on the flat disk radius and the depth of its run in the soil, the original dimensions of the ridge and physical and mechanical soil properties.
