Abstract

The invention relates to agricultural machinery, in particular to working bodies for inter-row processing of potatoes and other tilled crops in the ridge method of their cultivation. The purpose of the invention is to improve the quality of soil loosening and hilling of plants, as well as reducing energy intensity. Adjacent sectors 3-5 and 4-6 are set in pairs with opposite tilt angles to the axis of the drive shaft 1. Adjacent pairs of sectors, 3-5 and 4-6, and sectors 3,4,5 and 6 in the pair have angular displacements relative to each other. friend The cutting edge of each sector 3,4, 5 and 6 has the shape of an ellipse. The fastening point of sectors 3, 4, 5 and 6 on the drive shaft is placed on the minor axis of the ellipse with z Ј

A tool for tillage and cutting of ridges is known, the working body of which is a rotor mounted on an inclined shaft placed in a field (relative to the direction of movement of the aggregate) plane. Directly: the rotor is formed by two discs interconnected by plates, on which: the loosening elements are fixed. The same elements are installed on the outer side of the lower disc, which ensures loosening of the side surface of the ridge.

 On shaft 1, an even number is firmly fixed, the quality (at least four) of cutting elements: 3-6. At. this data is cutting ..--. sector elements are installed in pairs along a helix with some angular displacement oj relative to each other (Fig. 2) and different angles of rotation $ to the axis of rotation defined for each element (Fig. 3). Each of the sector cutting elements 3-6 is a / elliptical sector (Fig. 4), having a pointed tip I, a guide surface I, and a curvilinear cutting

edge, on the outer sides of their rigidly installed additional loosening teeth 7 (figure 1). To ensure constant depth and width of processing

the geometrical dimensions of the sector cutting elements 3-6 are taken such that, at a given angle of rotation, the lateral projection of them is the sector of a circle, and the angular displacement at provides such

their position on the shaft 1, in which the pointed tip I of the extreme element 5 or b adjoined the guide surface: the st of the II of the previous middle element (respectively 3 or 4), while the point

mounting sector cutting elements 3-6 to the shaft 1 is offset from the center of the conditional ellipse along its minor axis in the direction opposite from the cutting edge by the value of e (figure 4). ,

The working body works as follows.

When the shaft 1 rotates, the cutting sector elements 3-6 form two screw elements.

surface of the opposite winding with

variable pitch and angle of attack. Pointed tips of middle cutting sector elements (e.g., 3) are inserted into the soil in the middle between the rows

the formation which is finally cut off from the monolith by a curvilinear cutting edge and is displaced by the guide surface II (Fig. 4) back and to the side. When the formation descends from the guide surface II of the middle

cutting sector element into it inserts the tip of the I extreme sector (for example. 5). whereupon the formation finally loosens into separate edges, which is. The other guiding surfaces I are fed up and to the side, i.e. on the comb. Simultaneously lateral surface of the ridge

and the soil between the beds is loosened with additional loosening teeth 7 (Fig. 1).

Similarly, the second pair of cutting sector elements 4 IT b moves the soil to another ridge.

When this cutter operates, tensile and shear stresses predominate in the soil layer, which makes it possible to reduce the pull resistance of the aggregate.
