Middle Size Wheel loader

The shoveling and loading and unloading of the loader is realized by the movement of its working device. The working device of the loader is composed of bucket 1, boom 2, connecting rod 3, rocker arm 4, bucket cylinder 5, boom cylinder 6 and so on. The entire working device is hinged on the frame 7. The bucket is hinged with the bucket cylinder through a connecting rod and a rocker arm for loading and unloading materials. The boom is hinged with the frame and the boom cylinder for lifting and lowering the bucket. The turning of the bucket and the lifting of the boom are operated hydraulically.

The working device of the loader should be able to ensure that when the bucket cylinder is locked and the boom cylinder is lifted or lowered, the linkage mechanism makes the bucket move up and down or close to it, so as to prevent the bucket from tilting and spilling materials; When the arm is in any position and the bucket rotates around the hinge point of the boom for unloading, the inclination angle of the bucket is not less than 45°. After unloading, the bucket can be automatically leveled when the boom is lowered. Synthesizing the structural types of loader working devices at home and abroad, there are mainly seven types, namely three-bar, four-bar, five-bar, six-bar, and eight-bar according to the number of components of the linkage mechanism; According to whether the steering of the input and output rods are the same, it is divided into forward and reverse link mechanisms. The bucket structure of the loader used in earthmoving. The bucket body is usually made of low-carbon, wear-resistant and high-strength steel plates. The cutting edge is made of wear-resistant medium manganese alloy steel. The side cutting edge and the reinforced angle plate are all made of high-strength Made of ground steel material. There are four shapes of bucket cutters. The choice of tooth profile should consider factors such as insertion resistance, wear resistance and easy replacement. The tooth shape is divided into pointed teeth and blunt teeth. Tire loaders mostly use pointed teeth, while crawler-type loaders mostly use blunt teeth. The number of bucket teeth depends on the bucket width, and the bucket tooth pitch is generally 150-300mm. The bucket tooth structure is divided into two types: integral type and split type. Small and medium loaders mostly use the integral type, while large loaders often use the split type due to poor operating conditions and serious tooth wear. Split bucket teeth are divided into two parts: basic tooth 2 and tooth tip 1. Only the tip of the tooth needs to be replaced after worn-out .
