如今工程机械行业取得了长足发展，推土机的使用量也大幅增加。不过，在使用推土机之前，让我们先了解一下它。推土机是什么？它的分类和用途是什么？以下便是推土机的介绍。让我们一起来看看吧！

Nowadays, the construction machinery industry has made great progress, and the use of bulldozers has also increased significantly. However, before using the bulldozer, let's first understand it. What is a bulldozer? What is its classification and use? The following is the introduction of bulldozer. Let's have a look!

推土机是一种工程车辆，前方装有大型的金属推土刀，使用时放下推土刀，向前铲土，推泥、推沙、推石。推土刀的位置和角度可以调整。推土机可以单独完成挖掘、运输和卸载工作。具有操作灵活、旋转方便、工作面小、行驶速度快等特点。

Bulldozer is an engineering vehicle, with a large metal bulldozer in front. When in use, put down the bulldozer, shovel soil forward, push mud, sand and stone. The position and angle of the bulldozer can be adjusted. The bulldozer can complete the excavation, transportation and unloading work alone. It has the characteristics of flexible operation, convenient rotation, small working face, fast driving speed, etc.

推土机用途：

Purpose of bulldozer:

推土机是一种短距离自行式铲土运输机械，主要用于50~100m的短距离施工。推土机主要用于挖掘路堑，修建路堤、回填基坑、障碍物、积雪、平整场地等，也可用来完成松散物料在短距离内的铲堆和堆垛。

Bulldozer is a short-distance self-propelled shovel transport machine, which is mainly used for short-distance construction of 50~100m. Bulldozers are mainly used to excavate cuttings, build embankments, backfill foundation pits, remove obstacles, remove snow, level the site, etc. they can also be used to shovel and stack loose materials in a short distance.

当自行式铲运机的牵引力不足时，推土机也可用作辅助铲，用推土板推动。推土机配备松土器，可松土三、四级以上硬土、软岩或凿石，配合铲运机进行预松土作业，配合液压反铲挖掘装置、铰链板拖动等辅助工作装置进行挖掘、救援和拖动。推土机还可以使用吊钩牵引各种牵引机具（如牵引式铲运机、牵引式振动压路机等）进行操作。

When the traction of the self-propelled scraper is insufficient, the bulldozer can also be used as an auxiliary shovel to push with the bulldozer. The bulldozer is equipped with scarifier, which can loosen hard soil, soft rock or chisel stone above grade III and IV, cooperate with the scraper for pre scarifying operation, and cooperate with the hydraulic backhoe excavation device, hinge plate dragging and other auxiliary working devices for excavation, rescue and dragging. The bulldozer can also use the hook to pull various traction machines and tools (such as traction scraper, traction vibratory roller, etc.) for operation.

冷再生机租赁厂家再来讲讲推土机分类：

The rental manufacturer of cold regeneration machine will talk about the classification of bulldozers again:

1、按行走方式分类

1. Classification by walking mode

推土机可分为履带式和轮胎式。履带式推土机附着牵引力大，接地比压小（0.04-0.13mpa），爬坡能力强，但行驶速度低。轮胎式推土机具有行驶速度快、灵活性强、作业周期短、运输和转移方便，但牵引力小，适用于施工现场和现场工作频繁变更的情况。

Bulldozers can be divided into crawler type and tire type. Crawler bulldozer has large adhesion and traction force, low grounding pressure (0.04-0.13mpa), strong gradeability, but low driving speed. The tire bulldozer has the advantages of fast driving speed, strong flexibility, short operation cycle, convenient transportation and transfer, but low traction, which is suitable for the construction site and the situation of frequent changes in site work.

2、按用途分类

2. Classification by purpose

可分为通用型及专用型。通用型是根据标准生产的，广泛应用于土方工程中。专用型用于特定工况，有采用三角形宽履带板以降低接地比压的湿地推土机和沼泽地推土机、水陆两用推土机、水下推土机、船舱推土机、无人驾驶推土机、高原型和高湿工况下作业的推土机等。

It can be divided into general type and special type. The universal type is produced according to the standard and is widely used in earthwork. The special type is used for specific working conditions, including wetland bulldozers and swamp bulldozers that use triangular wide track shoes to reduce the grounding specific pressure, amphibious bulldozers, underwater bulldozers, cabin bulldozers, driverless bulldozers, bulldozers that operate under Plateau and high humidity conditions, etc.
