Embodiment Construction

[0031] figure 1The shown sand metering blocking device comprises a lifting magnet 6 whose lifting rod 7 acts as closing element 3 to close the outlet opening 4 of the sand container 2 . A sealing element 9 , preferably made of elastomer, is arranged on the lifting rod 7 . This sealing element 9 can be fastened to the rod 7 by means of a suitable support disc 10 and a fastening nut 11 . In the bottom area of ​​the sand container 2 is positioned a metering housing 14, the metering housing 14 comprising a plurality of sand inlet holes, preferably four sand inlet holes, all staggered at 90° around the periphery, the sand inlet holes of the sand container 2 Through the inlet hole it is conveyed to the outlet hole 4 along the arrow shown. These sand outlet holes enable an even, safe and complete flow of sand from the sand container and prevent sand deposits. The metering housing 14 is positioned in the sand container 2 apart from the mounting flange. This constructional concept ...

Abstract

The invention relates to a sand dosing and blocking device (1) for sand spreading systems for vehicles, particularly rail vehicles with drive, the invention having a sand supply container (2) with an outlet opening (4), which can be closed by a closing element (3), for the dosed release of sand to a conveyor unit (5) which is preferably pneumatically activated, wherein the closing element (3) is formed by a lifting rod (7) of an electrically activated lifting magnet (6). According to the invention, the lifting magnet (6) is arranged inside the sand supply container (2) in the area of the outlet opening (4).

Description

technical field [0001] The invention relates to a sand dosing and blocking device for use in a sand planting system of a vehicle, in particular a rail vehicle with a drive, comprising a sand container with a device suitable for passing through An outlet orifice closed by the closing element for discharging the metered sand to the preferably pneumatically operated conveyor unit. Background technique [0002] EP 1312488A2 discloses a blocking device for a sand metering device having a metering piston connected to a lifting magnet. In the closed position of the inlet channel of the metering device, the annular projection of the seal connected to the metering piston bears against the projection of the housing wall. To release the inlet channel, the projection is lifted off the protrusion by the metering piston. [0003] US 2325441A describes a sand planting device with a sand container, the bottom end of which is provided with an opening adapted to be closed by a cup-shaped va...
