Description

The invention relates to loading machines, in particular to continuous loading machines with scooping feet.

The purpose of the invention is to increase productivity by optimizing the trajectory of movement of the scooping paws and reducing the efforts to introduce them into the material.

FIG. 1 shows the working body of the loading machine, top view; in fig. 2 shows section A-A in FIG. one,

The working body consists of an inclined V-shaped feeder 1 with beveled leading edges, along which the wedge-shaped scaffold legs move in cross-section 2, the power cylinders 3 of displacement of the legs, the bodies of which cantileverly fasten on the swivel support 4, are placed above the legs, and the rods 5 are connected with raking paws in the front, not entering into interaction with the stack of the submersible material. The paws' movement path is defined by the guide grooves of the backward movement 6 and the forward and forward 7. Bottoms 8 and 9 of the grooves are inclined in length with a stepped transition, so that at the transition point of the finger 10 from the groove 6 to the groove 7 the bottom 8 is above the bottom 9, and at the point of transition from the groove 7 to the groove 6 the bottom 9 of the upper bottom 8.

The finger 10 is made with the possibility of free movement in the body of the foot 2, pressing the finger 10 to the bottom 8 (or 9) is carried out by means of a spring 11 supported in the arm 12. In the middle of the feeder is located the scraper conveyor 13, the fixture of the feeder to the loading machine is carried out by brackets 14,

To load the material, the tool is inserted into the stack, while

one of the legs is in the extreme extended position.

When extending the rod 5 of the power cylinder 3, the leg 2, moving along a path, which is defined by the configuration of the groove 7, is inserted into the stack of material. The finger 10 as it moves along the inclined bottom of the groove 7 moves in the body of the foot 2, compressing the spring 11. Reaching the end point of the groove, which corresponds to the full increase of the foot, the finger 10 enters into the action of the spring 11. contact with the bottom 8 of the groove 6. During the return stroke, the paw 2 moves along the path defined by the groove 6, the material is picked up and moved along the feeder to the scraper conveyor 13. As it moves along the inclined one. the bottom 8 of the groove 6, the finger 10 moves relative to the body of the paw 2 and compresses the spring 11. At the junction of the grooves 6 and 7, which corresponds to the end position of the paw, the finger 10 under the action of the spring 11 comes into contact with the bottom 8 of the groove 7. Due to the difference in the levels of the bottom at the joints of the grooves, the possibility of returning the groove to the passed groove is excluded when the cylinder rod is reversed.

During loading, the paws are alternately inserted into the stack of material, then the material is grabbed and moved along an inclined feeder to the conveyor.

The application of the invention provides an increase in the productivity of the machine due to an increase in the area of the material captured by the paws, reduced efforts to introduce the paws and material losses from shifting at the time of insertion of the paddle into the stack. -J.
