Abstract
Description
Technical Field
[0001] The invention relates to the technical field of roadbed construction, in particular to a multi-directional cutting device for road construction with self-regulating pressure. Background Art
[0002] During construction, in order to ensure the stability of the roadbed, a bulldozer can be used to level it first. Generally, mechanical excavation and manual leveling are used. The commonly used construction methods are on-site measurement, removal of surrounding debris, setting up temporary ditches, determining the excavation plan, and excavation and transportation of earth and stone. The roadbed is leveled by manual leveling. Only after the roadbed is leveled can the next step of paving be carried out. However, some roads require piles to be buried in the roadbed to make signs or guardrails. The traditional nailing method will not only cause problems such as loose screws, but the roadbed may also cause these road facilities to collapse after being heated and cooled, seriously affecting traffic conditions and even threatening the life and property of drivers.
[0003] Therefore, before the subsequent paving, the roadbed needs to be cut and opened in advance. Usually, manual grooving and excavator grooving are adopted. Manual grooving can accurately adjust the groove shape, but the efficiency is slow, and the roadbed is relatively hard, which will cause serious damage to the operator's body. Therefore, manual grooving is only suitable for small-scale grooving. For large-scale grooving, mechanical means can be used for excavation, but large equipment such as excavators are difficult to meet the requirements of pile burial accuracy, and large-scale damage to the roadbed often occurs. Some small equipment also requires special operators to conduct road surface surveys and roadbed shape profiling before they can be operated. Due to the different hardness of the roadbed, the equipment often has problems such as engine explosion and tooth breakage during operation. Summary of the Invention

The input sleeve 501 transmits power to the input gear 1301, and the input gear 1301 distributes the power. Then the output gear 1302 will drive the transmission shaft sleeve 1401 to rotate, and the transmission shaft sleeve 1401 drives the output shaft 1402 to rotate, and the cutting tool 6 rotates accordingly, and the cutting teeth 602 in the cutting tool 6 dig grooves, and driven by the power assembly 2 When cutting a pile burying groove on the roadbed, during the movement, the detection roller 9 will detect the roadbed and detect the hardness of the roadbed. The road surface information will be transmitted to the transmission tube 10 through the lifting rod 8, and the information will be fed back to the lifting hydraulic rod 503 in the gear box 5. The lifting hydraulic rod 503 will drive the cutting tool 6 to move up and down, thereby controlling the grooving depth, and the speed sensor 15 will sense the speed of the output shaft 1402, and control the elongation of the hydraulic cylinder 506 through the trigger state of the speed sensing switch 1507, thereby controlling the elongation length of the cutting teeth 602, thereby avoiding the problem of tooth breakage of the cutting tool 6 due to excessive pressure, and reducing damage to the cutting engine 4.
