Description

The invention relates to a mining machine-building industry, in particular to chainless feeding devices, cleaned combines. The aim of the invention is to equalize the loading of loads between the drive sprockets and to ensure the self-alignment of the drive sprockets on the slats. Figure 4.1 shows the feed mechanism, a general view; figure 2 is the same, the view in the plan; at 4 "g. Z - A-4 section at 4 mg.2; - at 4ig.4 g - the kinematic scheme of the feed mechanism. The feed processor of the shearer comprises a combine body 1 connected by means of pins 2 with a bracket 3 connected by means of pins 4 with a body 5 of the feed mechanism. Axles 2 and 4 are perpendicular to each other. Drive gears 6 are installed on the feed mechanism case 5, which interact with the rails 7 installed on the downhole and downhole sides of the conveyor 8. The axial displacement of the toonstein 3 relative to the combine body 1 is limited by sleeves 9 attached to trunnions 2. The feed mechanism of the shearer works as follows. Most of the feed gear transmission is transmitted to drive sprockets 6, interacting with the rails 7, resulting in the body 1 of the combine moving relative to the conveyor 8. At the same time, as a result of periodically variable forces on the executive bodies of the combine from cutting the coal and loading the destroyed part of it, the body I of the combine it performs oscillatory movements both in the plane of the formation and in the direction perpendicular to it. When the combine body 1 oscillates in the plane of the reservoir, the feed body case 5 does not participate in oscillatory movements as a result of rotation of the bracket 3 on the trunnion 4 relative to the feed mechanism arm 5, as a result of which the edge contacts of the sprocket teeth 6 and the rails 7 do not occur, therefore, the area of their contact remains unchanged. With fluctuations. The combine body 1 in the frontal plane of the formation (the plane perpendicular to the plane of the formation) the supply mechanism body 5 also does not participate in oscillatory movements of the combine body 1 as a result of rotation of the trunnions 2 of the bracket 3 relative to the combine body 1, as a result of which changes in the center distance between the drive sprockets 6 and the rails 7. The axial movement of the bracket 3 relative to the body 1 of the combine is limited by sleeves 9 attached to the trunnions 2.
