• practical experience has proved that the excavator bucket in the application of the whole process, the bucket teeth outside the bucket than inside the fast wear 30%, proposed to use for a period of time, the bucket teeth inside and outside the swap parts.
• digging bucket in the application of the whole process need to look at the office environment, to calculate the actual bucket teeth type, general ten square excavation, weathering storm sand, face coal, etc. have to use round head bucket teeth. Digging small pieces of hard solid rock with RC type bucket teeth, digging small pieces of coal road generally use TL type bucket teeth, TL bucket teeth can enhance the rate of coal out of the block. In specific applications usually customers love the generality of RC type bucket teeth, the proposal is not the condition of the general can not use RC type bucket teeth, with round head bucket teeth, due to RC type bucket teeth with a period of time in front of the edge of the wear, like a ‘clenched fist’ increased excavation friction resistance, consumption of driving force, and the straight mouth of the bucket teeth in the whole process of wear continues to maintain a sharp surface, reducing the friction resistance of excavation, saving Diesel fuel.
• excavator TouDaShiPin safety when driving way to enhance the use of bucket teeth is also very core, excavator TouDaShiPin in mentioning the hand when better not to collect digging bucket, if the driver while mentioning the arm, the side of the digging bucket so that the actual operation will make the bucket teeth suffered an upward driving force, so that the digging bucket from the upper side of the tear off, and then tear the bucket teeth, the actual operation posture should pay attention to the posture of the flexibility. Some excavator drivers in the change big arm, and send the arm posture is usually too much force, the digging river news speed to the rock “knock” or hard to the bucket fell on the rock, that will be the bucket teeth knocked broken, or non-tang easy to control the bucket knocked on the strong marks, the size of the arm knocked bad.
• the wear condition of the tooth seat on the excavator bucket is also very important to the use of the period of time, the tooth seat wear off 10% – 15% after the proposal to replace the tooth seat, due to excessive wear of the tooth seat and the bucket teeth in the middle of a large gap, so that the bucket and the tooth seat of the mutual cooperation, and bear the force of the point changed, the bucket teeth due to the change of the point of the force of the rupture.
• excavator drivers in the actual operation of the excavation of the perspective of the actual operation should pay attention to, as far as possible to excavate when grasping, bucket teeth digging down the vertical flat part of the worktable, or tilt angle tilt shall not exceed 120 degrees, to prevent because of the tilt is too large and break the bucket teeth. Also need to pay attention to do not have a relatively large friction resistance in the case of up and down shaking excavation arm, that will make the bucket teeth and teeth seat due to the upper and lower bearing force is too large and rupture, due to the majority of models and specifications of the bucket teeth of the structural mechanics of the structural design, did not take into account the upper and lower bearing force design program.
