Axis 12 pcs to mixed from its rear end 13 approximately PA 1/2 + of its length. The mass of the PC 4 with K 11 must be greater than 1 mass And 1 taking into account foreign layers and friction in the nodes and parts.

To limit the travel of the vehicle, the collar P 5 of ore-landing 6 has a baffle 14, After a vehicle has driven over езда 1 by rotating PC 4 around axis 12 through cables 7 and blocks 8, the mouth of the ore-landing opens 6, where the mountain mass is dumped. The back section of the ore-landing 6 is blocked by the PC 4 automatically under the action of K 11. Through the control unit P 1 returns to its original position, 1 sludge.

The invention relates to the mining industry and can be used to isolate the mouth of the ore pass when using self-propelled vehicles.

The purpose of the invention is to simplify the con. Structures and increased operational reliability.

The drawing shows the general scheme ^{of the} device for isolating the ore landing, a longitudinal section.

The device contains a platform 1, one end of a hinge attached to the base 2 of the discharge chamber 3, a rotatable cover 4 fixed at an angle to the horizon above the sleeve 5 of the ore landing 6 and completely blocking its cross section, the control unit including the flexible cable 7 and blocks 8, For more stable work is recommended to use two identical pairs of flexible cables 7 and blocks 8.

One end of the cables are attached to the drive element - platform 1, the end 9 is pivotally fixed to the base of the unloading chamber and installed with the possibility of lowering when a vehicle hits it, and the other end of the cables are attached to the front end 10 of the swivel cover 4 that holds the counterweight 11 , while the axis 12 of the pivot roof 4 is offset from the edge of its rear end 13, adjacent to the rear wall of the unloading chamber 3.

Platform 1, swivel cover 4 are made of steel I-beams, beams or channels, covered with sheet steel on top.

Counter load 11 is rigidly secured to the front end 10 swivel

caps 4. Counterloading can be made in the form of steel or cast iron castings. Swivel cover weight 4 s. the counterweight, 1 1 must be greater than the mass of the platform 1, taking into account extraneous layers and friction in the nodes and parts. The swivel cover 4 by the front end 10 (from the approach of the vehicle) under its weight rests on the collar of the sleeve 5 of the ore-landing 6, and the opposite rear end 13 from the bottom tightly adjoins the end of the rear wall of the unloading chamber 3. The axis 12 of the rotary cover 4 is offset from its rear end 13 approximately 1/4 of the length of the swiveling cover 4, the installation of which at an angle to the horizon makes it possible, in particular, to open it more easily with the help of the control unit.

To limit the progress of the vehicle, the collar of the sleeve 5 of the ore-landing gear 6 must have an end bar (stop) 14. For the same purpose, the platform 1 itself may have a protective visor (shown by a dotted line).

The device works as follows.

To the initial position of the cross section, the ore passes 6 are overlapped with the help of a solid rotary cover 4. The platform 1 is in the upper position.

The cross section of the ore pass 6 is opened by lifting the rotary cover 4 through flexible cables 7 and blocks 8 when

hitting the platform 1 self propelled

means of transport and lowering

her in a horizontal position, In

the open mouth of the ore passes 6 unload the rock mass.

The back section of the ore pass 6 is automatically overlapped. This happens when the account of the vehicle from platform 1 under the action of counter-load 11. In this case, platform 1 returns to its original position through the control unit.
