Fig. 2 is a schematic view of the mechanism of the working device of the self-discharging loader according to the present invention at the time of loading.
Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1 to 2, a working device of a dump loader according to an embodiment of the present invention is installed at a front end of the loader. The working device includes a front frame 1, a boom 2, and a bucket mechanism 3. The front frame 1 is arranged on the loader. The boom 2 is movably provided on the front frame 1 by being driven by a cylinder mechanism 4. The cylinder mechanism 4 includes a boom cylinder 41 and a boom piston rod 42 connected thereto, the boom cylinder 41 is provided on the front frame 1, and the other end of the boom piston rod 42 is connected to the boom 2.
