There are seven main structure types of both at home and abroad loader working device: according to different numbers of &nbsp;linkage components, loaders can be divided into three connecting rods type, four-connecting rods type, five connecting rods type, six connecting rods type and eight connecting rods type &nbsp;and so on; according to the swing directions of input and output rods can be divided into forward linkage components &nbsp;and reverse components and so on.<br /> Structures of &nbsp;earth working loader bucket : bucket made from low carbon, wear-resistant, high strength steel welding, cutting edge made of wear-resistant manganese alloy steel material, side-cutting edge &nbsp;and strength corner panels &nbsp;are made of high-strength wear-resistant steel materials.<br /> Bucket cutter shapes can be divided into four. Insert the tooth choice should take into account factors such as resistance, wear-resistance and easy to replace. Tooth tines and blunt teeth, wheel loader with pointed teeth, and crawler-mounted power on the use of blunt teeth. Depending on tooth number and according tothe width, tooth pitch is generally 150-300mm. Bucket tooth structures are whole type and split type, small and medium sized loading machines use monolithic, and large loaders due to poor working conditions, tooth wear, often using split type. Split type bucket tooth divided into basic tooth teeth &nbsp;and tooth tip，the tooth tip can be replaced after wore.<br />
