Problems solved by technology
The top of the rear hood of the existing excavator is hinged on the middle hood, which is not convenient for operators to check and maintain the components in the main hood
In response to this defect, some excavators (especially small excavators) are provided with side doors on the tail side of the main cover body, and locks are provided on the side doors to lock the side doors, but the use of locks to lock the side doors is not only costly, but also prone to side door Faults that cannot be opened, high repair costs

The invention discloses an excavator side door closing mechanism which comprises a middle cover, a rear cover, a side door and a closing component, wherein the upper side of the rear cover is hinged with a rear frame of the middle cover; one end of the side door is hinged with a side frame of the middle cover; the closing component is used for controlling opening and closing of the side door; theclosing component comprises a closing bracket I and a closing bracket II; the closing bracket I is arranged on the inner side of one end, close to the rear cover, of the side door; the closing bracketII comprises a mounting base and a pressing plate; the mounting base is of a plate-shaped structure and is arranged in parallel to the side door; the pressing plate comprises a connecting part and apressing part; the connecting part is connected with the mounting base; an included angle is formed between an inclined pressing surface of the pressing part and a plate surface of the mounting base;the inclined pressing surface is inclined in a direction far away from the mounting base from one end connected with the connecting part to one end close to the rear cover; when the rear cover is closed, a pressing part is inserted between the mounting base and the pressing part and propped against the inclined pressing surface to lock the side door. The excavator side door closing mechanism disclosed by the invention has the advantages of being solid in structure, convenient to operate, attractive in appearance, and the like.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an excavator side door closing mechanism. Background technique [0002] An excavator, also known as a backhoe, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. Excavators are mainly used for earth and stone excavation and loading, and can also perform operations such as land leveling, slope repair, hoisting, crushing, demolition, and ditching. Excavators are widely used in road construction such as roads and railways, bridges, urban construction, and airport, port and water conservancy construction. In recent years, with the acceleration of engineering construction, the application of excavators has become more frequent, and it has become one of the most important construction machinery in engineering construction.
