Description

one

The invention relates to mining engineering.

Harvesters with drum actuators are known for selective (separate) excavation of layers of complex structure consisting of two independent cutting parts, in which the excavation of minerals with varying power is carried out using a set of interchangeable drums or drums whose diameters correspond to average power of these layers.

However, in such combines, the full correspondence of the diameter of the drum to the power of the removable layer takes place only in the particular case; in all other cases, the drum is greater or less than the power of the layer of the mineral fossil. In addition, working with a set of interchangeable drums is extremely time-consuming, since with each significant change in the power of the interbed, the reels must be replaced.

The proposed executive body of the combine differs from the known ones in that the drums of each of its cutting parts are fixed in pairs on a swinging relatively fixed axis of the articulated articulated gearbox, the joint axis of which in the middle part is the axis of rotation for one drum and the swing axis for the other.

FIG. 1 schematically shows a combine with the proposed executive body, general view; in fig. 2 is the same, view along arrow A in FIG. one; in fig. 3 is a hinged gearbox, a section along BB in FIG. 1 and a section along BB; in fig. 4 shows the arrangement of the drums at different formation powers.

The combine consists of a support paiMbi / (see Fig. 1), a transverse and a longitudinal conveyor 2 and 3, two electric motors 4 and 5 of the working bodies, two main gearboxes 6, 7 of the working bodies, two handles, made in the form of spherical rioedi KtorovB 5 and I drums 10-13, waste cutting devices 14, controls and actuating cylinders.

Each gearbox articulated in the middle part (see Figs. 3 and 4) contains: two housings 15 and 16 connected with covers 17 and 18, gears 19-22 and two output shafts 23 and 24 with fixed " and they are drums. The axis of the shaft 23 is the axis of the articulation of the gearbox and at the same time the axis of gain of the drum 10 and the axis of swing of the drum 11.

The articulation of the articulation of the gearbox housings is accomplished with an O-shaped rubber seal 25. Gear wheels 19-22 are propelled from the main gearbox via gear 26 mounted on the output shaft 27, the axis of which is the swing axis of the entire hinged gearbox.

When the formation configuration changes, the spatial position of the drums 10 and // relative to the axis of attachment of the arm with pairwise drums to the engine changes, and the spatial positioning of the drums 12 and 13 occurs both relative to the above-mentioned axis and relative to the axis of the articulated gearboxes.

Subject matter

The executive body of the combine for selective excavation of layers of a complex structure, consisting of two independent drum-type cutting parts, characterized in that, in order to reduce losses and dilution during excavation of a useful mineral, each drum part’s drums are fixed in pairs on a swinging relatively stationary the axis of the articulated gearbox, the joint axis of which in the middle part is the axis of rotation for one drum and at the same time the axis of swing for the other.
