The invention relates to mining, in particular to machines for loading lumpy material in terms of ledges quarries, mines.

The famous design of the working body of the loading machine mounted with the possibility of reciprocating movement in the direction of the longitudinal axis of the machine to zacheciani and moving rocks (A.S. USSR 870311, MKI 65G 65/02. Loading machine/ Gshadow, Wegelin, Vol. - Declared 01.06.78. Publ. 07.10.80. Bull. No. 37).

Closest to the proposed is the working body of the loading machine containing the gutter where you installed, connected actuators with the opportunity to make a reciprocating movement relative to the trough (U.S. Pat. 2137694, IPC 65G 65/02. Loading machine/ Gshadow, Umiashankar, Avitrol, Eviciton. - Declared 21.04.98. Publ. 20.09.99. Bull. No. 26).

Volume of the rock mass that is moved in each cycle actuating elements depends on friction between the tray and dipped material.

The task of the device is increased productivity of the working body.

According to design this object is achieved in that the working body of the loading machine comprising a stationary chute and installed it with the ability to make reciprocating AC is the incarnation of interconnected control elements, the latter is in the form of rolls, one of which is a leading and equipped with overrunning clutches in the form of gears included in engagement with the mounted on the tray rails, one of which is mounted rotatably a leading roll in the direction of transportation of the material in the direct course, and the second in reverse, while the rolls are interconnected and the leading roller chain transmission.

The essence of the device illustrated by the drawings. Figure 1 shows the working body of the loading machine, figure 2 - he same, top view.

Working body of the loading machine includes a stationary chute 1 and installed it on the frame 2, the reciprocating movement of the hydraulic cylinder 3, which are interconnected control elements 4. Executive elements 4 made in the form of rolls, one of which 5 is the leading and equipped with overrunning clutches 6 and 7 in the form of toothed wheels 8 are included in engagement with the mounted on the tray rails 9 and 10, one of which 9 is mounted for rotation a leading roll in the direction of transportation of the material in the direct course, and the second 10 - in the reverse, when the rolls are interconnected and the leading roller chain transmission 11.

The device operates as follows. After loosening rocks working body of the loading machine of its anterior part of the implementation of AESA in a pile of lumpy rock mass in position, shown in figure 1.

Loading cycles begins with the work cylinder 3, under which the frame 2 with the attached rollers 4 is moved relative to the chute 1, carrying the rock mass to the discharge side of the working body. This toothed wheel 8 that is part of the engagement with the rack 10 through the overrunning clutch 7 causes the rotation in the direction of transportation of rock mass leading roller 5. The rotation of the rolls 4 are associated with the leading roller 5 chain transmission 11 provides additional movement of the material and increases the speed of movement of the rock mass with respect to the frame 2. The overrunning clutch 6 is in a disabled state.

After reversing cylinder 3 frame 2 carries out a movement in the direction of the pile lump of rock. At this time, the overrunning clutch 6 through gears 8, which engages with the rail 9, causes the rotation in the direction of transportation of rock mass leading roller 5 and connected with the last chain transfer rolls 11 4. The overrunning clutch 7 is in a disabled state.

The rotation of the roll 4 in the direction of the discharge portion during movement of the frame 2 in the direction of the pile turn push the lump of rock from cyclic to continuous.

Thus, the proposed working body of the loading machine benefits is but differs from existing counterparts, what is its design increases the movement speed of the rock mass, ensures the continuity of the process of the loading of the material during cyclic operation of the working body, which generally contributes to productivity and workflow efficiency.

Working body of the loading machine comprising a stationary chute and installed it with the ability to perform the reciprocating movement of the connected actuators, wherein the actuators are made in the form of rolls, one of which is a leading and equipped with overrunning clutches in the form of gears included in engagement with the mounted on the tray rails, one of which is mounted rotatably a leading roll in the direction of transportation of the material in the direct course, and the second in reverse, while the rolls are interconnected and the leading roller chain transmission.
