When selecting the underground loader, the braking performance of the loader must be fully considered, including three types of braking, parking braking and emergency braking. There are three types of brakes: shoe, clamp and wet. The driving mechanism of the brake usually uses a force adding device, and its power source includes three types: compressed air, air top oil and hydraulic pressure. Commonly used is the air top oil braking system, usually using a dual circuit braking system.

山東井下裝載機主要用于鏟，裝，卸，運土和石料，也可以輕度鏟土和硬土。如果更換不同的工作設備，則還可以完成推土，起重和裝卸其他材料的工作。在公路建設中，主要用于瀝青和水泥混凝土材料場的集料和裝料等作業(yè)。由于它具有快速的操作速度，良好的機動性和輕便的操作優(yōu)勢，因此發(fā)展迅速，成為土石施工中的主要機械。

Shandong underground loader is mainly used for shoveling, loading, unloading, transporting soil and stones, and can also shovel soil and hard soil slightly. If different working equipment is replaced, bulldozing, lifting and loading and unloading of other materials can also be completed. In highway construction, it is mainly used for aggregate and loading of asphalt and cement concrete material yard. Because it has the advantages of fast operation speed, good mobility and light operation, it has developed rapidly and become the main machinery in earth rock construction.

裝載機工作裝置由鏟斗1.動臂2.連桿3.搖臂4和轉斗油缸5.動臂油缸6等組成，整個工作設備被放在車架上，鏟斗通過連桿和搖臂和轉斗油缸鉸接，以裝卸材料。

The loader working device consists of bucket 1 Boom 2 Connecting rod 3 Rocker arm 4 and bucket cylinder 5 The whole working equipment is placed on the frame, and the bucket is hinged with the rotary bucket cylinder through connecting rod and rocker arm to load and unload materials.

裝載機作業(yè)時，工作設備應確保：當轉斗油缸關閉時，動臂油缸升起或降落時，連桿機構將鏟斗平滑或接近平滑，以免鏟斗傾斜并撒掉材料;

During the operation of the loader, the working equipment shall ensure that when the rotary bucket cylinder is closed and the boom cylinder is raised or lowered, the linkage mechanism will smooth or nearly smooth the bucket to prevent the bucket from tilting and scattering materials;

綜合國內外裝載機工作裝置的結構類型主要有七種類型，即連接桿機構的結構性不同，分為三桿，四桿，五桿，六桿和八桿;按輸入和輸出桿的轉向是否相同，分為正轉和反轉連桿機構。土方工程采用裝載機鏟斗結構，其斗體通常由低碳，耐磨和高強度鋼板焊接制成。切割刃采用耐磨的中錳合金鋼材料，側切割刃和加強角板均由高強度耐磨鋼制成。鏟斗切割刀的形狀分為四種。

There are seven main structural types of loader working devices at home and abroad, that is, the structure of connecting rod mechanism is different, which is divided into three rods, four rods, five rods, six rods and eight rods; According to whether the steering direction of input and output rods is the same, it is divided into forward and reverse linkage mechanisms. Earthwork adopts loader bucket structure, and its bucket body is usually made of low-carbon, wear-resistant and high-strength steel plate welded. The cutting edge is made of wear-resistant medium manganese alloy steel, and the side cutting edge and reinforcing corner plate are made of high-strength wear-resistant steel. There are four types of bucket cutters.

齒形選擇應考慮插入阻力，耐磨性和易于更換等因素。齒形分為尖齒和鈍齒。輪胎裝載機大多采用尖齒，而履帶裝載機大多采用鈍齒。斗齒的數量取決于斗齒的寬度，而斗齒的距離一般為150-300mm。斗齒結構分為整體和整體。中山東井下裝載機大多采用整體，而大型裝載機由于操作條件差，斗齒磨損嚴重而經常采用分體。分體式斗齒分為基本齒2和齒尖1部分。磨損后，只需要更換齒尖。

The factors such as insertion resistance, wear resistance and easy replacement shall be considered in the selection of tooth profile. The tooth profile is divided into sharp teeth and blunt teeth. Most tire loaders use sharp teeth, while most crawler loaders use blunt teeth. The number of bucket teeth depends on the width of bucket teeth, and the distance between bucket teeth is generally 150-300mm. Bucket tooth structure is divided into integral and integral. Most underground loaders in Zhongshan East are integral, while large loaders often use split because of poor operating conditions and serious bucket tooth wear. The split bucket teeth are divided into basic teeth 2 and tooth tip 1. After wear, only the tip needs to be replaced.
