The invention relates to a device for loading dump trucks mountain mass supplied by the excavator, and is designed to eliminate downtime excavators and dump trucks in the pit.

A device containing hopper and mounted underneath the inclined plate conveyor feeder, guide the Board in its head part (Vasiliev K.A. Transport units and warehouses. M., Nedra, 1991 s.204-205, RIS).

However, the disadvantage of this device is the possibility of downtime cars, trucks and excavators.

A device (prototype)containing hopper and mounted underneath the inclined plate conveyor - feeder placed on the support structure, the guide Board in the head part of the feeder, which can be used to load trucks in a career (Vasiliev A.A. and other Cars, trucks and their use in road construction. M., 1938, pp.28 - 30).

A disadvantage of the known device is that it cannot be used when providing continuous, with no downtime, work career excavator and loading without downtime cars, trucks mountain mass supplied by the excavator.

The technical result of the invention is the provision of consistent, with no downtime, load at least two career automatic is biles, trucks mountain mass, supplied by the excavator, and ensuring the smooth operation of the excavator.

The technical result is achieved in that the device for loading dump trucks containing frame, side, mounted on frame plate for placement on it supplied by the excavator rock mass and provided with a drive device to move according to the invention the plate is horizontally connecting the bottom edge of vertically oriented flanges and between the flanges with bearing on the plate and slide it along the boards posted by bilateral pluzhkovogo the resetter with working edges, limited by a cylindrical surface deflection toward each other, with the bottom side pluzhkovogo the dumper is equipped with a bracket placed in the longitudinal groove of the horizontal plate and connected to the circuit, closed on the back, deflecting and drive sprockets positioned below the horizontal plate, and the upper part pluzhkovogo the dumper is equipped carriages with the possibility of their interaction with the guides mounted on the upper edges of the sides, while the rock mass for subsequent filing in cars-trucks placed on both sides of the pluzhkovogo the dumper, which in the initial position located in the middle part of the plate. Pluzhkovogo sbra ivatel can be connected with two chains, and longitudinal grooves placed directly at the sides.

A device for loading dump trucks are presented in figure 1 is a longitudinal section, figure 2 is a plan of figure 1, figure 3 - section a - a of figure 1.

The device consists of equipped with skids 1 frame 2 on which is fixed a horizontal plate 3, bounded on the sides of the vertically oriented flanges 4 and 5. Between the flanges 4 and 5 with bearing on the plate 3 and slide it along the boards 4 and 5 are placed bilateral pluzhkovogo the resetter 6 with working edges 7 and 8, is limited by a cylindrical surface deflection toward each other. From the bottom side pluzhkovogo the resetter 6 provided with a bracket 9, is placed in the longitudinal groove 10 of the horizontal plate 3. The bracket 9 is connected to the circuit plate or krupasindhu) 11, closed on two working 12 and 13, a deflector 14 and 15, and the drive 16 stars. All stars placed under the horizontal plate 3. The upper part pluzhkovogo of resetter 6 provided with carriages 17 and 18 with the possibility of their interaction with the guides 19 and 20, secured to the upper edges of the sides 4 and 5. Pluzhkovogo the resetter 6 can be connected to the two circuits 11 and longitudinal grooves 21 and 22 are placed directly at the sides 4 and 5 (figure 3). This mountain mass 23 and 24 for subsequent filing in the car-sa is usualy 25 and 26 are placed on both sides of the pluzhkovogo of resetter 6, which in the initial position located in the middle part of the plate 3 (Fig 1 and 2).

The device operates as follows. Initial filling device is feeding the rock mass excavator (not shown) on both sides of (23 and 24) from pluzhkovogo of resetter 6 with the placement of the rock mass 23 and 24 on the horizontal plate 3 between the flanges 4 and 5 (figure 1) until complete filling of the volume corresponding to the capacity of the trucks (25, 26). While this operation is carried out in the breaks between innings for loading dump trucks. In the case when another car-truck loaded by an excavator, and at this time to slaughter arrives following a car-truck, the last (25 or 26) is sent to the device. Turns on the drive sprocket 16, resulting in one direction or another (car-truck 25 or 26) by using the chain 11 (one or two) begins to shift pluzhkovogo the resetter 6.

When moving pluzhkovogo of resetter 6 on the plate 3 between the flanges 4 and 5 of the rock mass (23 or 24) is reloaded into the body of a dump truck (25 or 26). After the departure of the loaded car-truck can load the next, and the excavator can apply the rock mass in the vacant portion of the device. When movements pluzhkovogo of resetter 6 due to the EOI is to interact carriages 17 and 18 with the guides 19 and 20 excludes the possibility of "floating" pluzhkovogo of resetter 6. Having working edges 7 and 8 of cylindrical shape ensures complete emptying of the device from the rock mass and decrease spacer efforts on the carriage 17 and 18.

Features of the invention provide trouble-free, no downtime, functioning as an excavator and dump trucks.

1. A device for loading dump trucks containing frame, side, mounted on frame plate for placement on it supplied by the excavator rock mass and provided with a drive device to move, characterized in that the plate is horizontally connecting the bottom edge of vertically oriented flanges and between the flanges with bearing on the plate and slide it along the boards posted by bilateral pluzhkovogo the resetter with working edges, limited by a cylindrical surface deflection toward each other, with the bottom side pluzhkovogo the dumper is equipped with a bracket placed in the longitudinal groove of the horizontal plate and connected with a chain, closed on the back, deflecting and drive sprockets positioned below the horizontal plate, and the upper part pluzhkovogo the dumper is equipped carriages with the possibility of their interaction with the guides mounted on the upper edges of the sides, with mountain mA the sa for subsequent filing in cars-trucks placed on both sides of the pluzhkovogo the resetter, which in the initial position located in the middle part of the plate.

2. The device according to claim 1, characterized in that pluzhkovogo the resetter is connected with two chains, and longitudinal grooves placed directly at the sides.
