A road construction finishing device for compacting after loosening soil

Abstract

The invention discloses a road construction finishing device used for ripping and punning. The road construction finishing device used for ripping and punning comprises a vehicle body, a first motor,and a punning column; the left side of the lower end of the vehicle body is provided with a front caterpillar band rotating wheel, and the right side of the lower end of the vehicle body is provided with a back caterpillar band rotating wheel; a lower end output shaft of the first motor is fixedly provided with a threaded rod; the threaded rod is sleeved with a nut; the right side of the nut is fixedly arranged on a fixing plate; the lower end of the fixing plate is fixedly provided with two parallel soil ripping rollers; the punning column is arranged in a first cavity; the upper end of the first cavity is communicated with a second cavity through a communication pipe; a rotating disc is arranged in the second cavity; the rotating disc is provided with a fixing column; the fixing column is fixedly provided with a rotating rod through a fixing sleeve pipe; the lower end of the rotating rod is connected with an upper telescopic adjusting rod via hinge joint. The road construction finishing device is suitable to be used for ground with large soil blocks or hard soil, can be used for punning of grounds of different loose degrees, and narrow roads and courtyards with short and narrow doors.

Description

technical field [0001] The invention relates to a road construction finishing device, in particular to a road construction finishing device for compacting after loosening soil. Background technique [0002] Ram is a Chinese word with the original meaning of reinforcement, and the extended meaning is to lay a solid foundation, and it is mostly used in the construction industry. Use heavy objects to make it fall freely repeatedly, and tamp the foundation or filling soil and stone to improve its compactness. Ramping, tamping, or tamping, originally used to tamp the foundation with hard objects such as stones by manpower when building a house. Usually, more than 2 people cooperate to complete the work. Now the work of compacting the foundation is changed to mechanical compaction, also known as electric compaction. [0003] Before laying asphalt or concrete, it is necessary to level and compact the dirt road. In the process of road construction, it often happens that the road f...

Problems solved by technology

[0003] Before laying asphalt or concrete, it is necessary to level and compact the dirt road. In the process of road construction, it often happens that the road foundation is not comprehensive, the foundation is not flat and firm enough, and the quality of the road foundation is not guaranteed. Asphalt or concrete pavement is undulating, and it is easy to form cracks or pits under rain and heavy pressure

[0004] At present, large tamping machines are not suitable for tamping narrow courtyards with narrow roads and gates. The small tamping machines on the market are not suitable for tamping the ground with large clods or hard soil. Controlled compaction of ground with varying degrees of porosity
