00 The invention relates to mountain importance. and more specifically to ventilation lintels, erected (lm in mine workings equipped with conveyors. Known jumper for workings equipped with conveyors, including transverse overlapping with sealing box, contouring conveyor with discharge head C The disadvantage of this device is low tightness due to rapid wear of the sealing windows of the guiding conveyor elements at lancing them about the transported material .. In addition, the well-known device cannot be used to seal the scrubber The purpose of the invention is to increase reliability while maintaining the ventilation mode of operation. The goal is achieved by the fact that in a ventilation bridge for workings equipped with conveyors that include a transverse overlap with a sealing box with a contouring head, the discharge head of the conveyor a rigid wall with a counterweight is installed, hingedly connected to the upper part of the duct and forming a discharge chute in the lower part, inside which is located a sector hatch going on with the drive .vrascheni. Figure 1 shows a jumper, a general view; Fig. 2 shows the same view (Plan; Fig. 3 shows the same, when oversize is passed through the discharge chute. The jumper consists of a sealing duct 1 fixed on the transverse overlap 2 along the contour of the window 3. Front rigid wall 4 With the counterweight 5, the hinges 6 are connected to the upper part of the box 1 and form with it in the lower part a discharge chute 7, in which the pie gate 8 is mounted with a 9-speed drive. The box 1 covers the discharge head of the conveyor 10, and the discharge chute 7 is located above tail section of the next conveyor 11. Between the duct 1 and the rigid wall 4 there is a sealing gasket 12. The actuator 9 is included in the electrical circuit (not shown) of controlling the conveyor line and starts after starting the conveyor 11 before starting the conveyor 10. The paddle blades .8 overlap the section of the groove 7 as during operation of the conveyors 10 and 11, so when they are stopped. The 4 is deflected at the hinges 6 and misses the oversize (Fig. 3). After the passage of the oversized rack 4, it returns to its original position due to the weight of the counter-load 5, thereby providing a sealed seal. jumpers. The invention can be used in workings equipped with both belt and scraper conveyors.
