Problems solved by technology

When constructing the vertical foundation groove of the arched skeleton, the operator usually excavates the arc groove by manipulating the excavator attachment with the milling machine. However, in the actual excavation process, the operator only digs with experience, so The arc grooves produced are irregular and the standards are inconsistent, and overbreak or underbreak often occur

Abstract

The invention discloses a grooving early warning device for a milling machine, comprising: a milling head, the milling head includes a milling head and a roller shaft connected to one end of the milling head in transmission, the milling head The other end is connected with the installation end of the excavator attachment. An adjustment bracket is provided on the outer surface of the milling head, and a distance sensor is installed on the adjustment bracket. The distance sensor is used to detect the The distance of the forming board on the soil surface, and the detected distance signal is sent to the groove depth monitor, and the groove depth monitor takes an early warning action after receiving the distance signal. The invention can remind the operator when milling and digging grooves to different groove depths, so as to avoid the phenomenon of overcutting and undercutting.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a groove early warning device for a milling machine. Background technique [0002] There are various forms of slope protection for traditional high-speed railway subgrades, among which arched reinforced concrete skeleton + reserved core soil + vegetation protection is one of the common forms of protection. When constructing the vertical foundation groove of the arched skeleton, the operator generally excavates the arc groove by manipulating the excavator attachment with the milling machine. However, in the actual excavation process, the operator only digs with experience, so The arc grooves produced are irregular and the standards are inconsistent, and overbreak or underbreak often occur. Contents of the invention [0003] In order to solve the above problems, the present invention provides a device that can detect and remind the operating driver of the distance ...
