The pick is a drilling cutting tool, most people understand the type of pick is limited to the shape or model, some people have an understanding of the application of different mechanical equipment, and then a more detailed classification may be very few people know, the classification of the pick in accordance with what is the division.
The pick can be divided into types roughly according to the following five cases.
1. Classified according to the type of machinery used
The pick is first used as a mechanical accessory, and it is also a high consumable. Different types of machinery use different types of picks. According to the shearer pick, boring machine pick, rotary digging machine pick and so on several types. They use different pick models, for example, roadheader picks use S135 picks, shearers use U85/U94/U170 and other pick models.
2, according to the shape of the pick classification
The shape of the pick is also a more intuitive classification. According to the shape, the pick can be divided into two types: knife-type pick and pick-shaped pick. Knife picks are also called flat picks and pick picks are also called conical picks. Of course, there is also a bullet pick, itself also belongs to a pick-shaped pick.
3. Classification according to rock hardness
The fundamental role of the pick is to cut the rock, the hardness of the rock layer is different, the type of pick required is also different. Rarely, we can divide the cutting teeth into: coal cutting teeth, half rock teeth, full rock teeth (strengthening teeth), hard rock teeth, etc. Each geological condition corresponds to a different pick type.
4. Classified by industry
According to the use of industry on the pick classification, can be roughly divided into mining pick and engineering pick two categories. Generally speaking, the mining pick is used for coal mining, and the engineering pick is mainly used for the maintenance and construction of highway tunnels.
5, according to the characteristics of the pick classification
When the pick market is highly competitive, pick manufacturers will pursue differentiated competition to add some characteristics to the pick. Based on the different characteristics, the pick can be divided into non-sparking pick, spin pick and so on. These two kinds of cutting teeth, one claims not to produce sparks, one claims to be able to spin in order to achieve the purpose of uniform anti-eccentric wear.
