The cold knowledge in the excavator, the old driver is really good!

Hello everyone! The hunting driver market that hires excavator drivers is here again. There have been several issues about the little knowledge on the excavator, and many digging friends like and replies have also been received, especially thank you for your support! Today, let’s take a look at what little-known knowledge on the excavator we have brought. Gossip less narrative, the book belongs to the text.
First of all, let’s understand the types of excavator bucket teeth, and then slowly describe below. In the picture, you can see three bucket teeth for different purposes. The flat teeth are what we often call earthmoving teeth, and their tips are like blades. The same sharpness, so the resistance to soil cutting will be very small, even if it is worn, the soil is always cut with the least resistance surface, so this kind of bucket tooth is the most suitable and economical choice for earthmoving operations. Another canine-like bucket tooth is called tl bucket tooth. The abbreviation of Tiger Long translates to very long tiger tooth, which also has a special image. This kind of bucket tooth is generally used for coal mine operations. The RC bucket tooth in the bottom right corner is the rock tooth we usually call. This kind of bucket tooth is relatively strong and designed for digging stones, so it does not have a sharp blade. It is wise to choose what type of tooth for what job type!
The above is just a generalization of the general types of bucket teeth, or if you like to observe, you may find out why your bucket teeth always grind faster on both sides, while the middle is relatively better. Why?
It can be seen that this bucket tooth is really weather-beaten... and the degree of wear on both sides is much more serious than that in the middle. The main reason for this is that the friction force on both sides of the bucket teeth when cutting into various materials is greater than Caused by the middle bucket teeth. When the bucket teeth cut into the material in an instant, the friction force of the three bucket teeth in the middle is evenly distributed, but the friction force of the two bucket teeth is unevenly distributed, which will cause this situation over time. Of course, the most important thing in the excavation work is that there is still a lot of work to brush the slopes, which will cause the two sides to wear too fast.
The effect of the replacement is that the bucket teeth are actually useless to this extent. They should be replaced early. This not only improves the work efficiency, but also greatly improves the hydraulic system of the excavator, the consumption of each pin and even the fuel.
After talking about the bucket tooth story, let’s take a look at another piece of cold knowledge. Dear excavator drivers, I don’t know if there are any small black spots on your excavator glass similar to the ones in the pictures below. Of course not every excavator glass Yes, you can see if there is any glass in your excavator. Even if it doesn't, there will be a circle of black. This black spot is similar to the ceramic sintering method, which burns the colored enamel onto the glass and is embedded in the glass. So do you know what these little black dots are for?
Small black dots of varying sizes are evenly distributed on the edge of the glass. There is a reason for it. In fact, these small black dots play a function of preventing the glass from breaking easily. So how does it do it?
Speaking of this, we need to understand the principle of thermal expansion and contraction. In fact, everyone knows this principle, and it does not need to be too detailed. The main thing is that objects expand when heated and contract when cold. Because the temperature around the glass and the temperature rise in the middle of the glass are different. The transition of these small black spots from large to small is actually to gradually transfer the heat from the edge of the glass frame to the glass to ensure that it will not explode due to thermal expansion. Even if there is a heavy rain after the summer, your glass It will not break. This is one of the credits of the small black dots. Of course, there is also the aesthetic effect. Because the edges of the windows are fixed with black glass glue, in order to integrate with the edges, black dots are used to overdo it.
