By the gravity of the machinery itself, it is suitable for various compaction operations, causing deformation and compaction of the compacted layer. It is also divided into two categories: steel wheel type and tire type.

碾轮构造有光碾、槽碾和羊足碾等。光碾应用普遍，主要用于路面面层压实。采用机械或液压传动，能集中力量压实突起部分，压实平整度高，适于沥青路面压实作业。

The roller structure includes a smooth roller, a groove roller, and a sheep foot roller. Smooth rolling is widely used and mainly used for compaction of road surface layers. Adopting mechanical or hydraulic transmission, it can concentrate force to compact protruding parts, with high compaction flatness, suitable for asphalt pavement compaction operations.

按轮轴布置有单轴单轮、双轴双轮、双轴三轮和三轴三轮等种。以内燃机为动力，采用机械传动或液压传动。一般前轮转向，机动性好，后轮驱动。为改善转向及碾压性能，宜采用铰接式转向结构和全轮驱动。前轮框架和机架铰接，以减少路面不平时的机身摆动。后轮和机架为刚性联接。采用液压操纵、用液压缸控制转向。前后碾轮均装有刮板以碾轮上粘结物。还装有喷水系统，用于压实沥青路面时，对碾轮洒水以防沥青混合料粘附。为增大作用力还可在碾轮内加装铁、砂、水等加大压重。

There are various types of wheels arranged according to their axles, including single axle single wheel, double axle double wheel, double axle three wheel, and three axle three wheel. Powered by an internal combustion engine, using mechanical or hydraulic transmission. General front wheel steering, good maneuverability, rear wheel drive. To improve steering and rolling performance, it is advisable to use an articulated steering structure and all wheel drive. The front wheel frame and frame are hinged to reduce the body swing caused by uneven road surfaces. The rear wheel and frame are rigidly connected. Using hydraulic control and hydraulic cylinders to control steering. Both the front and rear grinding wheels are equipped with scraper plates to remove the adhesive on the grinding wheels. It is also equipped with a water spraying system, which is used to spray water on the roller to prevent adhesion of the asphalt mixture when compacting the asphalt pavement. To increase the force, iron, sand, water, etc. can also be added to the grinding wheel to increase the weight.

拖式振动压路机可以有效地压实各类土壤及岩石填方，适用于现代高速公路、机场、路堤填方、海港、堤坝、铁路、矿山等工程建设施工

The towed vibration roller can effectively compact various types of soil and rock fills, and is suitable for construction projects such as modern highways, airports, embankment fills, seaports, embankments, railways, mines, etc

在滚筒上装置许多凸块的压路碾。由于凸块形似羊足故称羊足碾，亦称羊脚碾。凸块形状有羊足形、圆柱形及方柱形等。滚筒轴支承于牵引机架轴承上，扩大使用范围。滚筒内可装水、砂或铁砂以增加碾压重量。在滚筒前后的机架下方装有梳状刮板，以凸块间粘嵌的泥块。

A roller with many protrusions installed on the drum. Due to the shape of the convex block resembling a sheep foot, it is called a sheep foot roller, also known as a sheep foot roller. The shapes of convex blocks include sheep feet, cylinders, and square columns. The roller shaft is supported on the traction frame bearing to expand its range of use. The drum can be filled with water, sand, or iron sand to increase the rolling weight. A comb shaped scraper is installed below the frame before and after the drum to remove mud blocks stuck between the protrusions.

拖式羊足碾由牵引机拖行。自行式羊足碾也称捣实压路机。羊足碾单位压力大，使填料均匀，有捣实作用，压实度大，尤其对于硬性粘土，适用于压实粘性土壤及碎石层。尤其对于硬性粘土，凸块有搅拌、揉搓和捣实作用，有捣实作用，使填料均匀，上下铺层粘结好避免分层。广泛用于路基、垫层和堤坝等工程的压实。

The tractor type sheep foot roller is towed by a tractor. Self propelled sheep foot roller, also known as tamping roller. Sheep foot roller has a high unit pressure, making the filling material uniform and has a compaction effect. It has a high degree of compaction, especially for hard clay, and is suitable for compacting cohesive soil and gravel layers. Especially for hard clay, convex blocks have the functions of stirring, kneading, and tamping, making the filling uniform. The upper and lower layers are well bonded to avoid layering. Widely used for compaction of roadbed, cushion layer, and embankment projects.

自行式羊足碾在滚筒中还可装激振装置，制成振动捣实压路机，利用激振力增大压实效果，滚筒内可装水、砂或铁砂以增加碾压重量。扩大使用范围。

The self-propelled sheep foot roller can also be equipped with an excitation device in the drum to make a vibrating compaction roller, which uses the excitation force to increase the compaction effect. The drum can be filled with water, sand, or iron sand to increase the compaction weight. Expand the scope of use.

羊足碾的主要技术参数为机重和单位压力。由于凸块形似羊足故称羊足碾

The main technical parameters of a sheep foot mill are machine weight and unit pressure. Due to the shape of the convex block resembling a sheep's foot, it is called a sheep's foot roller
