UA52733C2 - Working element of a cultivator - Google Patents

Abstract

A working element of a cultivator wherein a C-like post is equipped with elastic plates placed one after another at its back side and which are also fixed in their upper part and additionally fastened with the aid of clamps in two points, in combination with unilateral razor with a knife.

Description

The invention belongs to agricultural engineering, in particular to working bodies for soil cultivation.

The working body of the cultivator is known (see application Me1575962, class A 01 B 35/22), which contains a C-shaped rack, an additional elastic rack, below which is hinged a foot that vibrates in the vertical plane.

This design perceives significant resistance when moving in the soil due to the lack of vibrations of the paw in the horizontal plane and does not ensure its complete loosening and trimming of weedy plants due to the imbalance of the amplitude of vibrations of the paw under the influence of variable resistance of the soil.

The task of the invention is to increase the intensity of loosening of the soil and reduce the resistance to chipping of the soil layer.

To achieve this, the working body of the cultivator is proposed, which includes a C-shaped rack, an auxiliary rack and a foot, and is also equipped with reinforcing elastic plates located one after the other on the back side of the C-shaped rack, fixed in the upper part and additionally fixed with clamps in two points in combination with a single-sided razor with a knife fixed in the lower part of the rack.

A one-sided razor with a knife, creating sign-changing moments due to the heterogeneity of soil density, at the same time smoothes the peaks of vibration amplitudes, due to the mutual friction of elastic plates on a C-shaped rack, chips blocks of soil of smaller volume and mass, ensuring better sliding and their descent from the razor , in comparison with the paw, which oscillates only in the vertical plane.

Figure 1 shows the working body of the proposed cultivator. Fig. 2 is a front view. Fig. 3C is a top view.

The working body of the cultivator contains a C-shaped elastic rack 1, elastic plates 2, clamps 3, a knife 4 and a single-sided razor 5. The elastic plates 2 are installed on the back side of the C-shaped rack 1 and are installed in the upper part, additionally fixed with clamps C at two points . A one-sided razor 5 with a knife 4 is fixed in the lower part of the rack. The working body of the cultivator works as follows. A one-sided razor with a knife 4 due to the inhomogeneity of the density of the soil and the cantilever arrangement bends the rack 1 in a longitudinal plane and creates moments in a horizontal plane. Thus, the razor oscillates in two planes. Due to the friction between the elastic plates 3, the peaks of the oscillation amplitudes are smoothed out, which allows the working body to work in a smooth amplitude-frequency mode, which allows you to chip soil blocks of smaller volume and mass, while ensuring better sliding and their descent from the razor due to the resulting vibration working body

The use of the proposed working body of the cultivator will reduce the resistance and increase the intensity of action on the soil, which will ensure the improvement of the soil structure and the water-air regime. 1 2 From 2
