Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic road cutting machines, specifically a hydraulic road cutting machine that facilitates tool replacement. Background Technology

[0002] The easy-to-change-blade hydraulic road cutter is a type of hydraulic road cutter designed for quick replacement and installation of cutting blades.

[0003] Based on the above, the inventors have discovered that while there are many hydraulic road cutters on the market, the cutting blades of ordinary hydraulic road cutters easily overheat during the cutting process due to prolonged operation, which can easily lead to blade breakage and reduce the lifespan of the cutting blades. Furthermore, existing hydraulic road cutters require workers to directly fix the protective shell onto the outer surface of the cutting blade, which necessitates complete disassembly and replacement of the entire device when the blade wears out, significantly increasing the operator's workload and reducing the device's practicality. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a hydraulic road cutter with easier blade replacement, aiming to achieve greater practical value.

A check valve is fixed to the top of the water pump. A water pipe is provided on the inner wall of the check valve. The outer wall of the water pipe is fitted into the inner wall of the hydraulic road cutter body.

[0008] As a preferred technical solution of this utility model, the bottom end of the hydraulic road cutter body is provided with a perforated plate, the inner wall of the perforated plate is matched with the outer wall of the water pipe, and a guide groove block is fixed at the bottom end of the perforated plate, the guide groove block is provided on one side of the cutting tool.

[0009] As a preferred technical solution of this utility model, both sides of the guide groove block are fixed with ring plates, and the inner walls of the two ring plates are threaded with screws, the top ends of the two screws are threaded with the inner wall of the hydraulic road cutter body.

[0010] As a preferred embodiment of this utility model, the installation mechanism includes:

[0011] A cover plate, the outer wall of which matches the inner wall of the protective cover, is disposed at one end of the cutting tool.

[0012] As a preferred embodiment of this utility model, two connecting columns are fixed on one side of the cover plate, and two fixing plates are fixed on the outer wall of the protective cover. A groove is provided on one side of each of the two fixing plates, and the inner wall of each groove matches the outer wall of the connecting column.

[0013] As a preferred embodiment of this utility model, the inner walls of both connecting columns are provided with limiting columns, and the outer walls of both limiting columns are fitted with the inner walls of the groove.

[0014] As a preferred embodiment of this utility model, the cross-sectional area of ​​the inner walls of the two grooves is matched with the cross-sectional area of ​​the outer wall of the connecting column.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution uses a guide block positioned below the main body of the hydraulic road cutter to engage the inner wall of the orifice plate with the outer wall of the water pipe. Two screws are threaded onto the inner wall of the ring plate until their tips are threaded onto the inner wall of the hydraulic road cutter body. This securely mounts the guide block below the main body. A water pump draws cold water from the tank into the water pipe, which is then sprayed onto the outer wall of the cutting blade via the guide block. This effectively cools and rinses the outer side of the cutting blade during cutting, preventing overheating and potential breakage due to prolonged operation, thus improving the device's performance.

[0017] 2. In this solution, by fitting two limiting posts onto the top of the fixed plate, the limiting posts are separated from the top of the fixed plate. Then, the cover plate is used to drive the two connecting posts to separate from the inner wall of the groove opened on one side of the fixed plate, causing the cover plate to separate from the inner wall of the protective cover. This makes it easier for workers to quickly replace the cutting tools installed on the inner wall of the protective cover, avoiding the need to disassemble the entire device for replacement, reducing the operational burden on workers, and facilitating the normal use of the device.
