Hydraulic support

The invention relates to a hydraulic support which comprises a base, and the base is provided with a first side part; the first device is hinged to the first side part, the first device comprises a coal plough plate and a telescopic part, the coal plough plate is hinged to the first side part, one end of the telescopic part is hinged to the coal plough plate, the other end of the telescopic part is hinged to the first side part, and the telescopic part is hinged to the second side part. The telescopic piece can drive the coal ploughing plate to rotate around the hinged center of the coal ploughing plate and the first side portion. The coal plough plate of the first device can rotate through the telescopic piece, so that coal gangue accumulated in front of the base is discharged to the outer side of the base, the coal gangue is efficiently removed, and the situation that moving of the hydraulic support is affected due to accumulation of the coal gangue is avoided. 本发明涉及一种液压支架，其包括底座，所述底座具有第一侧部；第一装置，所述第一装置与所述第一侧
