LOADING MACHINE Russian patent published in 1998 - IPC

FIELD: load-handling machinery and equipment. SUBSTANCE: loading machine has undercarriage with electrical and hydraulic equipment, loading attachment which is made up of bucket with support and hydraulic cylinder for side unloading, bucket arm, and hydraulic cylinders for lifting and digging. These components create four-link mechanism for bucket lifting. Arm of loading attachment is made in the form of three-dimensional L-shaped lever. Located in right angle of L-shaped lever is turning axle of bucket support. Long end of bucket arm is connected by means of axle with undercarriage frame. Short end of bucket arm is connected with undercarriage frame through lifting hydraulic cylinder. Hydraulic cylinders for lifting and digging are installed symmetrically relative to longitudinal axis of loading machine . Pivot pins which connect aforesaid cylinders with undercarriage frame are located in one axis. Relation of length of opposite links of four-link mechanism to each other is equal to 1.0-1.3. This allows to ensure simultaneous penetration of bucket working edge into pile of material and lifting of bucket at digging and loading with material. Aforesaid embodiment of loading machine increases its productive capacity, reduces overall dimensions and mass of machine. EFFECT: higher efficiency. 1 cl, 4 dwg
