The pins on the crank can be placed at a distance from its axis equal to the radius of the bottom. The pins on the crank can be placed at a distance from its axis greater than the radius of the bottom. Contgroup may be in the form of a rectangular parallelepiped. Replaceable sleeve can be made with a slit cut along generatrix of the cylindrical surface with the width of the cut is larger than the diameter of the pin.

The shutter for the ore passes is shown in figure 1, a side view when the shutter is open, figure 2 is a vertical section with a closed shutter, figure 3 - section a-a of figure 1, figure 4 is a side view when the shutter is open for the option with the placement congresa extended for the CoE figure 5 is a longitudinal section through the pin, 6 - section b-B on figure 5, figure 7 is the same for sleeves with slit neckline.

The shutter contains placed below the outlet 1 of 2 ore passes two mounted on the cranks 3 and 4 cylindrical bottoms 5 and 6 with the possibility of rotation in the vertical plane in opposite directions about a horizontal axis 7 and 8. Axis 7 and 8 are placed with the outer sides of the vertical walls of the socket 9 and parallel to them. Cylindrical bottoms 5 and 6 on the cranks 3 and 4 fixed cantilever length of the arc corresponding right corner and the direction of the free ends of the end plates 5 and 6 to the inside of the pipe 9. The kinematic connection between the cranks 3 and 4 is made in the form attached to the axes 7 and 8 of other cranks 10 and 11. The free ends of the cranks 10 and 11 are connected with the rods 12 and 13 of the two power cylinders 14, which are made with two rods.

The power cylinders 14 is oriented horizontally and placed with a gap relative to the other two walls of the socket 9. In the initial position when the shutter is open the cranks 3 and 4 are oriented horizontally, and the other cranks 10 and 11 with the walls of the pipe 9 form an angle α=45 degrees.

Inside the pipe 9 at the level of the axes 7 and 8 and in parallel they fixed saddle visor 15 (2 and 3)overlapping in terms of the end edge of the cylindrical bottoms 5 and 6 when closed, satwa the E. Gable visor 15 is placed with the intersection of the axis of symmetry 16 of the socket 9. R is the crank radius, r is the radius of the additional crank, the width of the outlet pipe, α-remove the crank axle from the inner surface of the wall of the socket.

On each crank 3, 4 fixed properly oriented to him and aimed in the direction opposite from the cylindrical bottom 5, 6, two cantilever pin 17 and 18. Pins 17 and 18 mounted with the possibility of free accommodation in the holes congresa 19, which has the shape of a rectangular parallelepiped.

Contgroup 19 based on the cranks 3, 4 are placed on the pins 17, 18 replaceable sleeve 20 and 21. On the opposite side of contgroup 19 is fixed by nuts 22 and 23 placed on the cut ends of the pins 17 and 18. The minimum height of interchangeable bushings 20 and 21 adopted by more than the value of the removal of the α axis of the crank 3, 4 from the inner surface of the wall of the pipe 9.

Pins 17 and 18 on the crank 3, 4 can be placed at a distance from its axis 7, 8, equal to the radius R of the cylindrical bottom 5, 6. Pins 17 and 18 on the crank 3, 4 can be placed at a distance of R0from its axis 7, 8, the larger the radius R of the cylindrical bottom 5, 6. Replaceable sleeve 20 and 21 can be performed with slot cutout 24 for forming a cylindrical surface with a width of the cutout 24 is larger than the diameter of the pins 17 is 18.

The cranks 3, 4 and cylindrical heads 5, 6 are made with ribs 25, 26 and 27, 28.

The shutter for the ore passes operates as follows. When the shutter is open the cranks 3 and 4 attached to them cylindrical bottoms 5 and 6 occupy a horizontal position. This position corresponds to the most advanced of the power cylinder 14 to the rods 12 and 13 and the placement of other cranks 10 and 11 at an angle α=45 degrees to the vertical walls of the socket 9. Thanks to this mountain free weight unloaded from the ore passes 2 through its discharge outlet 1.

For closing the shutter and the overlap outlet 1 of 2 ore passes include the power cylinders 14, with the retractable rods 12 and 13 rotate in different directions cranks 10 and 11. When turning the cranks 10 and 11 together with them turning axis 7 and 8, together with turn to a straight angle towards each other and secured to them the cranks 3 and 4 with cylindrical heads 5 and 6.

Thus due to the torque generated by contiguously 19 and aimed in the direction of the nozzle 9, throughout the arc of rotation of the cranks 3, 4 with cylindrical heads 5 and 6, the free edge of the cylindrical bottoms additionally pressed to cross them the rock mass, and leaves the power cylinders 14.

Thanks to this work effort on the rods 12 and 13 of the power cylinder 14), the public are reduced. Due to this, may be correspondingly reduced the diameter of the power cylinder 14 and durable dimensions and weight, and increases the reliability of the overlap outlet 1 shutter.

In the position corresponding to the vertical location of the cranks 3 and 4 with the possibility of joining the walls of the socket 9, the rods 12 and 13 slide fully into the power cylinders 14 that off. Cylindrical bottoms 5 and 6, crossing the stream discharged from the ore passes 2 rock mass their free edges, to this moment are under the gable peak 15, providing full coverage of the outlet 1 of 2 ore passes and stopping the release of his rock.

For opening the shutter with the provision of the release of the rock mass of the ore passes rods 12 and 13 of the power cylinder 14 is moved in the opposite direction, allowing the cylindrical heads 5 and 6 are displayed outside of the pipe 9. When this power cylinders 14 are additionally loaded due to the torque generated by contiguously 19. However, due to the fact that upon opening of the shutter is not the intersection of rock by the free edges of the cylindrical bottoms 5 and 6, the total load on the rods 12 and 13 of the power cylinder 14 is no more load on them when you open the shutter. So running with the shutter contiguously 19 on the cranks 3, 4 correspond to what her orientation pins 17 and 18 on the cranks 3, 4 allows the efficient use of load-bearing capacity of the power cylinder 14.

Due to the fact that with the release of the rock mass through the gate and in the course of the overlap outlet 1 discharged from the ore passes 2 mountain mass is split into two streams saddle visor 15, significantly reduced the resistance offered by the mountain mass at its intersection cylindrical bottoms 5 and 6. Moreover, directly under the canopy 15 is free from the rock mass area, eliminating the possibility of jamming of its individual pieces between the cylindrical bottoms 5 and 6. In addition, due to the fact that the console attached to the cranks 3 and 4 cylindrical bottoms 5 and 6 in the process of crossing the stream of the mountain masses are shifted with minimal clearance relative to the fixed walls of the pipe 9, the resistance to their movement also reduced in comparison with the shutter of the prototype, as with the mountain mass interact only the front free edge of the cylindrical bottoms 5 and 6.

Replaceable sleeve 20 and 21 allow you to adjust the amount of torque generated by controlroom 19, and the amount of force impact of the free edges of the cylindrical bottoms 5 and 6 on the rock mass at closing of the shutter due to the choice of bushings greater height.

The presence of saddle peak 15 also reduces the load on to structive elements of the shutter in its closed position. The design of the shutter allows for the given cross-sectional dimensions (In) pipe 9 to accommodate the actuators 14 of the respective dimensions, allowing in turn to block the pipe 9 is increased in size with a console mounted on the cranks 3 and 4 cylindrical bottoms 5 and 6 is also increased in size. Load (voltage) from the bending moments acting on the cranks 3 and 4 and the cylindrical bottoms 5 and 6, is reduced through the respective ribs 25, 26 and 27, 28.

Interchangeable bushings 20 and 21 with slotted cutouts 24 reduces the complexity of the work when replacing bushings in the regulatory process parameters shutter.
