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.

碾輪構(gòu)造有光碾、槽碾和羊足碾等。光碾應(yīng)用普遍，主要用于路面面層壓實。采用機械或液壓傳動，能集中力量壓實突起部分，壓實平整度高，適于瀝青路面壓實作業(yè)。

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.

按輪軸布置有單軸單輪、雙軸雙輪、雙軸三輪和三軸三輪等種。以內(nèi)燃機為動力，采用機械傳動或液壓傳動。一般前輪轉(zhuǎn)向，機動性好，后輪驅(qū)動。為改善轉(zhuǎn)向及碾壓性能，宜采用鉸接式轉(zhuǎn)向結(jié)構(gòu)和全輪驅(qū)動。前輪框架和機架鉸接，以減少路面不平時的機身擺動。后輪和機架為剛性聯(lián)接。采用液壓操縱、用液壓缸控制轉(zhuǎn)向。前后碾輪均裝有刮板以清除碾輪上粘結(jié)物。還裝有噴水系統(tǒng)，用于壓實瀝青路面時，對碾輪灑水以防瀝青混合料粘附。為增大作用力還可在碾輪內(nèi)加裝鐵、砂、水等加大壓重。

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.

拖式振動壓路機可以有效地壓實各類土壤及巖石填方，適用于現(xiàn)代高速公路、機場、路堤填方、海港、堤壩、鐵路、礦山等工程建設(shè)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

在滾筒上裝置許多凸塊的壓路碾。由于凸塊形似羊足故稱羊足碾，亦稱羊腳碾。凸塊形狀有羊足形、圓柱形及方柱形等。滾筒軸支承于牽引機架軸承上，擴大使用范圍。滾筒內(nèi)可裝水、砂或鐵砂以增加碾壓重量。在滾筒前后的機架下方裝有梳狀刮板，以清除凸塊間粘嵌的泥塊。

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.

拖式羊足碾由牽引機拖行。自行式羊足碾也稱搗實壓路機。羊足碾單位壓力大，使填料均勻，有搗實作用，壓實度大，尤其對于硬性粘土，適用于壓實粘性土壤及碎石層。尤其對于硬性粘土，凸塊有攪拌、揉搓和搗實作用，有搗實作用，使填料均勻，上下鋪層粘結(jié)好避免分層。廣泛用于路基、墊層和堤壩等工程的壓實。

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.

自行式羊足碾在滾筒中還可裝激振裝置，制成振動搗實壓路機，利用激振力增大壓實效果，滾筒內(nèi)可裝水、砂或鐵砂以增加碾壓重量。擴大使用范圍。

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.

羊足碾的主要技術(shù)參數(shù)為機重和單位壓力。由于凸塊形似羊足故稱羊足碾

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
