Working device of wheel loader
Wheel loaders excavation, loading and unloading materials operation is achieved through
the movement of the working device.Wheel loader working device is composed by the bucket, boom, connecting rod, rocker and bucket cylinder, boom cylinder.
The entire working device hinged on the frame.
The bucket is articulated to the bucket cylinder by connecting rods and rocker arms for loading and unloading
of materials.Boom and frame, boom cylinder hinged to lift the bucket. Bucket flip and boom movements using
Wheel loader operation work device should be able to ensure that:when the bucket cylinder lock,
boom cylinder lift or landing, the link mechanism to move the bucket up and down so as not to tilt
the bucket and scattered material.When the boom is in any position, the bucket rotates around
the hinge point for unloading, the bucket inclination angle is not less than 45 °,
and the bucket can be automatically leveled when the boom is lowered after being unloaded.
There are mainly seven types of structure types of working equipment, which are divided into three types,
four types, five types, six types and eight types depending on the number of components of
the linkage mechanism.Teeth Divided into spiky teeth and cog teeth, wheel loaders use spiky teeth,
while the skid loader more use of blunt teeth.
Bucket teeth depending on the number of bucket width, fighting gear is generally 150-300mm.Tooth structure is divided into two types of integral and split, small and medium-sized loaders to use more integrated, and large loader due to poor operating conditions,
bucket teeth wear serious, often using split. Split teeth are divided into basic tooth and tooth tip two parts,
only need to replace the tooth tip after wear.
