The present invention is to simplify the construction and increase the efficiency of loading the digging machine near the bottom. In the well-known tunneling processor containing an Executive body, including the boom housing and the cutting crown feeder with toe, protobothrops device protobothrops the device is installed at the bottom facing the ground part of the housing boom and is a plate featuring the shape of a rectangular trapezium, and the lower side of the plate is at the cutting crowns, and most turned to the toe of the feeder, and a plate rigidly mounted on a shaft which is displaced to the lower side and is mounted in a socket made in the bottom facing the ground part of the housing boom, with the possibility of rotations is of the plate relative to its longitudinal axis, in this case the arrows on either side of its longitudinal axis is made stops at a distance, providing the pivot plate on the corner α, 30°≤α≤45°.

Mapping declared digging machine with the prototype allows to make a conclusion about the absence in the latter of signs similar to a distinctive signs with the stated tunneling machine:

- protobothrops the device is installed at the bottom facing the ground part of the housing boom and is a plate having the shape of a rectangular trapezium, and the lower side is at the cutting crowns, and most turned to the toe of the feeder;

- plate rigidly of saraline on the shaft, which is shifted to lower side and is mounted in a socket made in the bottom facing the ground part of the housing boom, with the possibility of rotation of the plate relative to its longitudinal axis;

on the housing boom on either side of its longitudinal axis is made stops at a distance, providing the pivot plate on the corner α, 30°≤α≤45°.

The set of features of the proposed technical solution is different from the prototype and known analogues and should not be explicitly studied the prior art, therefore, the authors believe that the object is new and involves an inventive step an Invention involves an inventive step and in the that combination of traits, namely:

- protobothrops the device is installed at the bottom facing the ground part of the housing boom and is a plate having the shape of a rectangular trapezium, and the lower side is at the cutting crowns, and most turned to the toe of the feeder;

- plate rigidly of saraline on the shaft, which is shifted to lower side and is mounted in a socket made in the bottom facing the ground part of the housing boom, with the possibility of rotation of the plate relative to its longitudinal axis;

on the housing boom on either side of its longitudinal axis is made stops at a distance, providing the pivot plate on the corner α, 30°≤α≤45°;

solves the problem:

- simplifying the design and improving the efficiency of loading the digging machine near the bottom.

These characteristics are related to each other so that when the removal of one of them disappears produced by the invention of the technical result.

The invention also represents a step in the development of technology and is progressive, as it allows to increase the efficiency of loading the digging machine near the bottom and to simplify the design protobothrops device.

Continuous miner, which claimed the invention may find wide application in g is modaliases industry and other sectors of the economy, i.e. is industrially applicable technical solution. The achievement of the technical result, when the work of the digging machine is provided that:

- protobothrops the device is installed at the bottom facing the ground part of the housing boom and is a plate having the shape of a rectangular trapezium, and the smaller side is at the cutting crowns, and most turned to the toe of the feeder. This design allows you to place protobothrops device between the cutting crown and feeder, and place the plate parallel to the soil generation and near her during the work of the Executive body;

- plate rigidly of saraline on the shaft, which is shifted to lower side and is mounted in a socket made in the bottom facing the ground part of the housing boom, with the possibility of rotation of the plate relative to its longitudinal axis, this solution provides a rotating plate protobothrops device at a given angle in one direction or another under the influence of the breed. The rotation of the plate is due to the difference of the squares located from the axis of rotation under the influence they breed during displacement of the Executive body;

on the housing boom on either side of its longitudinal axis is made stops at a distance, providing the pivot plate is and the angle α equal to 30°≤α≤45°.

This design allows you to limit the rotation of the plate protobothrops device at a given angle and to ensure that the plate protobothrops device in the moving direction of the Executive body.

The essence of the claimed invention is illustrated the accompanying drawings. In the drawings shows:

Figure 2 - General view of the digging machine (top view);

Figure 3 - mount protobothrops device on the boom of the Executive body;

Figure 4 - location of the plate protobothrops device during operation.

Continuous miner contains (1-4) the Executive body 1, including the arrow 2 with case 3 and the cutting crown 4, the feeder 5 with toe 6, protobothrops device 7. Protobothrops device 7 is installed at the bottom facing the ground of the chassis 3 arrows 2 and is a plate 8 having the shape of a rectangular trapezium, and the smaller side is at the cutting crown 4, and most turned to the toe 6 of the feeder 5 and the plate 8 is rigidly fixed on the shaft 9, which is shifted to lower side and is mounted in a socket 10, is made at the bottom facing the ground of the chassis 3 arrows 2 with the possibility of rotation of the plate 8 relative to its PR the longitudinal axis, on the housing 3 arrows 2 on either side of its longitudinal axis is made stops 11 on the distance, providing the pivot plate 8 on the corner α, 30°≤α≤45°.

The work of the digging machine is as follows: during operation of the digging machine loading of the rock mass is carried out by the feeder 5.

Loading rock mass on the chest of the face to the toe 6 of the feeder 5 is difficult because of the impossibility of feed of the feeder to the breast slaughter. For loading of the rock mass near the bottom lower Executive body 1 in the down position and make moving it in the horizontal plane. When moving the Executive body 1 to the left plate 8 together with the shaft 9 is rotated to the right in the socket 10. The rotation of the plate 8 is a mountain mass acting on the plate 8. Due to the fact that the square plate 8 located on opposite sides of the shaft 9, are not identical, the rotation of the plate 8 will result in the exposure of the rock mass over a larger area until it stops 11, thus forming an inclined plane directed from the cutting crown 4 to toe 6 of the feeder 5. During displacement of the Executive body 1 in the horizontal plane of the rock mass is moved along the inclined surface to the toe 6 of the feeder 5.

Next, pitfall 5 makes further shipment of rock from the face. P and the moving of the Executive body 1 to the right plate 8 rock-loading device 7 together with the shaft 9 is rotated to the left and further the process is repeated also moves the rock mass on an inclined plane directed in the direction of the feeder. The rotation plate 8 is at an angle from 30 to 45°that is optimal to move the rock mass.

We offer continuous miner due to the presence protobothrops device that is installed at the bottom facing the ground part of the housing boom, which is a plate having the shape of a rectangular trapezium, mounted on the shaft for rotation around its longitudinal axis, with the housing boom stops limiting the rotation of the plate, allows to simplify the design protobothrops device, to make it less cumbersome and bulky, to increase the efficiency of loading of the rock mass near the bottom.
