Introduction to the components of the excavator

The digging machine has realized the integration of driving and operation, and 1-2 operators can successfully complete the digging and drilling of various soil pits. Today, Xiaobian will introduce the knowledge about the digging machine in detail.

　　Digging machines, tree-planting digging machines, and ground drills are adapted to a variety of different geology and areas, and various corresponding ground and ground equipment are complete.You can choose the most suitable tree planting digging machine for you according to your requirements.The digging machine consists of an engine, clutch, reducer, drill bit and control device.The engine mostly uses a two-stroke air-cooled gasoline engine with a power of 1.2 to 3.7 kilowatts, and its power drives the drill bit through the clutch and reducer for operation.The clutch is the connecting device between the engine and the working parts, and a centrifugal friction clutch is generally used.When the engine reaches a certain speed, the centrifugal force generated by the clutch's active disc hammer overcomes the tension of the spring, and the clutch automatically engages and transmits power to the drill bit through the reducer.The reducer is an important part of the digging machine. Its role is to change the speed of the engine into the working speed of the drill bit. There are cylindrical gear reducers, worm gear reducers, cycloid gear reducers and other types.It is more common to use cycloid needle gear reducer, which has the characteristics of relatively large deceleration, small size, light weight, low noise and stable transmission.The control device often adopts a detachable handle structure, which can be configured for single or double operation.The drill bit consists of a drill tip, a blade, a soil guide piece and a drill pipe.The drill tip plays a positioning role, the blade is used to cut the soil, and the soil guide piece mainly plays the role of lifting the soil.During operation, the drill bit moves vertically downwards, cutting the soil under the action of torque and axial force, and the cut loose soil rises along the working surface of the soil guide sheet, and is transported to the surface and thrown away around the pit.According to the shape of the soil guide piece and blade, the drill bit is divided into three types: spiral type, blade type and scimitar type.The drill bit can also be equipped with a drill pipe sleeve and a protective cover to prevent the drill pipe from being entangled in grass and play a safety protection role.In order to enable the drill bit of the digging machine to be unearthed automatically, the machine is equipped with a reversing mechanism.The speed of the drill bit is generally 200 to 300 rpm, and its circular linear speed is about 3 meters per second, so as to ensure that the soil that is lifted out will not be thrown too far, and the drill bit is made of manganese steel to make it harder.It can be effectively implemented for hard soil, super hard soil, clay, permafrost, etc., and can meet the best work requirements.
