Stump crusher

A stump crusher comprising interconnected and interacting assemblies, which are:

• a hydraulic motor assembly (1) on the side of a working machine implement, comprising a hydraulic motor housing (10) and a mounting plate (11) attached to the end of the machine implement for attaching the stump crusher to the working machine implement;
• a hydraulic system necessary for controlling the hydraulic motor (12) arranged in a housing (2) of the hydraulic motor;
• a gearbox (20) connected to the hydraulic motor (12) and attached to a gearbox housing (21), to the lower end of which is attached to a gearbox flange (22), to which is attached a blade holder (3) of the stump crusher,
• characterised in that
• the blade holder (3) of the stump crusher consists of a circular mounting plate (31) of the blade holder, which is attached with fasteners to the gearbox flange (22) at the lower end of the gearbox housing (21);
• attached to the centre of the circular mounting plate (31) is a blade holder tower (32), at the end of which is the cone (33) of the stump crusher;
• the blade holder tower (32) is supported from two sides by tower reinforcement ribs (34) to ensure rigidity, the top end of which is welded to the circular mounting plate (31) and the lower end to the blade holder of the stump crusher;
• at the lower end of the blade holder (3) of the stump crusher are arranged horizontal blade holders (35), which are approximately ⅔ of the way from the blade holder tower (32) supported by a horizontal blade holder reinforcement rib (36), the top end of which is attached to the perimeter of the mounting plate (31) of the blade holder;
• a step is formed in the horizontal blade holder (35) of the stump crusher, to which the replaceable blade (37) of the stump crusher is attached.
