SU491343A1 - Working body for digging root crops - Google Patents

Description

one

The invention relates to the field of agricultural machinery, namely, machines for digging up root crops, for example, sugar beet roots.

A working tool for digging up root crops is known, which contains a squeeze vnlku, made in the form of counter-rotating, their cone-shaped tips mounted at an angle to the longitudinal-vertical plane of symmetry of the working body. However, such a working body does not provide the required degree of loosening of the soil layer, and this in turn contributes to damage to root crops.

In order to increase the crumbling efficiency of the soil layer in the proposed working body, a cultivator in the form of a flat knife is located below the tips in the plane of symmetry of the working body.

The drawing schematically shows the proposed working body. It contains a cultivator 1 and an active clutch release fork, made in the form of counter-rotating, their conical tips 2 and 3, installed at an angle to the longitudinal-vertical plane of symmetry of the working body. The fork lugs are driven by shaft 4 and gears enclosed in gearbox housing 5. Vyzhimna fork and ripper secured to the rack 6. Last performed

figured for the purpose of providing the possibility of the location of a disk or chain-lap topying apparatus over the working body. Rack 6 working body connected to the frame of the harvesting machine. The depth of the ripper in the soil in the drawing is indicated by the letter a.

Works proposed working body as follows.

The growing cone-shaped tips 2 and 3 loosen the soil around the root 7 at some depth. The magnitude of the penetration of the tips into the soil is established by the minimum, based on the condition that the roots are seized with a fork.

The ripper located below the fork loosens the soil, disrupting the connection of the root crop with it. After this, the root crop comes in contact with the rotating tips of the moving fork. The rotating tips extract the root crop from the loosened soil and transfer it to the placement area of the lifting gear of one type or another.

When the working body moves, the cultivator acts on the soil in the longitudinal and transverse directions. The zone of soil loosening is deflected from the vertical passing through the toe of the ripper to an angle determined by the angles of its inclination to the horizon and the friction of the soil.

on steel. The shape of the loosening zone is a trapezoid with a lower base equal to the width of the toe of the ripper. Angles between the bottom of this trapezoid and the sides of the rabbi

AND

90 N. Angle 0 depends on the physicomechanical properties of the soil and is 40-50 °. Since this angle is much larger than the angle of taper of the body of the root, the latter’s connection with the soil is broken over its entire surface with a small constructive width of the ripper itself. This ensures easy removal of root crops from the soil.
