1.齒根處的加強保護
1. Enhanced protection at the tooth root
長臂挖掘機齒根安裝板的加強非常有必要，如果在此處的加強不好，會導致磨損將劇烈，牙齒怎么也裝不上去了。對于此處的加固可以采取兩種方案，一種是貼加強筋，一種是包耐磨塊。需要注意的是，貼加強筋的做法簡便，經濟，但是焊接時要注意不能與齒根的焊縫產生疊焊，這樣會影響齒根焊接強度。
It is very necessary to strengthen the mounting plate of the tooth root of the long-arm excavator. If the reinforcement is not good here, the wear will be severe and the teeth will not be installed. Two schemes can be adopted for the reinforcement here, one is to stick the reinforcing rib, and the other is to wrap the wear-resistant block. It should be noted that the method of pasting stiffeners is simple and economical. However, it should be noted that there is no overlap welding with the weld of the tooth root during welding, which will affect the welding strength of the tooth root.
2.邊板及側邊加強
2. Side plate and side reinforcement
邊板的劇烈磨損會使挖斗的有效斗容減小，影響生產力。同時，邊刀也起到利于切入物料，保護邊板的效果，所以挖斗需安裝邊刀。長臂挖掘機由于側邊并不是高磨損區，故側邊的加強不用太堅固，以免影響挖斗的整體重量。
The severe wear of the side plate will reduce the effective bucket capacity of the bucket and affect the productivity. At the same time, the edge knife also plays a role in cutting materials and protecting the edge plate, so the bucket needs to be installed with the edge knife. Since the side of the long-arm excavator is not a high-wear area, the reinforcement of the side should not be too firm to avoid affecting the overall weight of the bucket.
3.底板加強
3. Bottom plate reinforcement
底板加強是非常有必要的。底板的加強筋要選擇堅硬、耐磨的長型板材做原料，要保護挖斗的整體形狀，以免影響切入角度，影響產能。加強筋的焊接要順著原機筋板焊接的方向，在兩塊板上疊焊。
It is very necessary to strengthen the base plate. The reinforcing rib of the bottom plate shall be made of hard and wear-resistant long plate, and the overall shape of the bucket shall be protected to avoid affecting the cutting angle and productivity. The reinforcement shall be welded on two plates in the same direction as the original reinforcement plate.
4.挖斗內面的加強
4. Strengthening of the inner surface of the bucket
長臂挖掘機廠家的小編建議內面加強使用硬面堆焊，雖然價錢高，耗時長。但是它的耐磨性跟實效性是更強的，或者也可以選擇貼部分加強筋，不宜過多。
Xiao Bian, the manufacturer of long-arm excavator, suggested to strengthen the use of hard surfacing on the inner surface, although the price is high and the time is long. However, its wear resistance and effectiveness are the strongest, or you can choose to attach some stiffeners, not too much.
