Description

Convenient maintenance structure of excavator multiway valve and tailless excavator Technical Field The application relates to the technical field of excavators, in particular to a convenient maintenance structure of a multi-way valve of an excavator and a tailless excavator. Background The multiway valve plays a critical role as a key component of the excavator. It is responsible for controlling various actions of the excavator including digging, rotating, lifting, etc. The precise execution of these actions depends on the precise adjustment of the multiplex valve. Typically, the multiplex valve is mounted to the bottom of the cab of the excavator in a position that is both convenient to operate and relatively concealed. However, when the multiplex valve malfunctions and requires maintenance, a worker must take specific measures. This typically involves lifting the entire cab to provide access to the multiplex valve for inspection and maintenance work. Although this maintenance approach ensures that maintenance personnel have sufficient space to operate, it is relatively cumbersome, time consuming and labor intensive, which is not cost effective for routine maintenance work because it requires specialized equipment and additional time investment. Disclosure of utility model The utility model aims to solve the problems and provide a convenient maintenance structure of a multi-way valve of an excavator and a tailless excavator. The technical scheme of the application is realized as follows: In a first aspect, the application provides a convenient maintenance structure of a multi-way valve of an excavator, wherein the maintenance structure is positioned on a floor of a cab of the excavator, the cab is provided with a containing groove for containing the multi-way valve, and an upper opening of the containing groove is formed on the floor of the cab; The maintenance structure includes: A shielding plate movably installed on the cab floor such that the shielding plate covers or opens a top opening of the receiving groove; a bolt detachably mounted on the shielding plate, the bolt being used for fixing the shielding plate at the bottom of the cab so as to cover the top opening of the accommodating groove; The seat of the cab is movable back and forth along the axis of the excavator. In a second aspect, the application also provides a tailless excavator, which is provided with the convenient maintenance structure of the multi-way valve of the excavator. The advantages or beneficial effects in the technical scheme at least comprise: Through detachable shielding plate, this shielding plate is used for covering and closing the holding tank opening of multiple unit valve top to the convenience in the maintenance process of excavator multiple unit valve has been realized. The novel design enables workers to easily contact the internal structure of the multi-way valve during maintenance operation, and further improves maintenance efficiency and operation safety.
