Loading device for machine and machine and loading method

Abstract

The invention discloses a load loading device of a machine, which comprises a bucket and a lifting arm pivotally connected with the bucket, wherein, the two sides of the bucket are respectively formed with a first ear plate and a a second lug on the inner side, the end of the lift arm is disposed between the first lug and the second lug and is pivotally connected to the first lug and the second lug pivotal connection, so as to realize the pivotal connection between the lifting arm and the bucket, and it is characterized in that: the length of the gap between the lifting arm and the first ear plate is shorter than the length of the gap between the lifting arm and the bucket The length of the gap between the second lugs. The invention also relates to a machine and a method of loading a load.

Description

Technical field [0001] The present invention relates to a loading device for loads, and more specifically, to a loading device for loads of a loader. The invention further relates to a machine having the load loading device and a method of loading a load using the device. Background technique [0002] Machines such as loaders used in construction machinery are equipped with work tools to complete the required work tasks. The work tools of loaders are usually buckets. The bucket is lifted and lowered by a lifting arm, which is usually connected to the body It is pivotally connected and extends from the body. A beam is connected between the lifting arms. The beam is usually welded between the two lifting arms. The beam supports the rocker arm at the same time, and the rocker arm controls the turning of the bucket through a cylinder connected to it. . In the prior art, the end of the lifting arm is pivotally connected with the ear plate extending from the bucket to realize the piv...

Problems solved by technology

In the prior art, the end of the lifting arm is pivotally connected to the lug protruding from the bucket to realize the pivotal connection between the bucket and the lifting arm, and the end of the lifting arm is usually located in the middle of the two lugs position, there is a spacer between the ear plate and the end of the lifting arm, when the machine is working on an uneven working surface, the bucket will tilt during the loading process, when the bucket tilts to one side , the outer side of the lifting arm at the high point is pressed inward by the outer ear plate, and correspondingly produces a compressive stress toward the inside of the lifting arm at the welding seam between the beam and the lifting arm, while the lifting arm at the low point The inner side of the arm is pushed by the inner ear plate to the outer side of the lifting arm, and correspondingly produces a tensile stress towards the outer side of the lifting arm at the welding seam of the beam and the lifting arm. In particular, due to the problem of machining accuracy, the two The lift arm and lugs can be asymmetrical, the distance from the end of the lift arm to the two lugs is different, creating the problem that when the bucket is tilted, the outside of the lift arm at the high point does not align with the outside lugs Contact, only the inner side of the lift arm at the low point is in contact with the inner lug, the full weight of the bucket and its load applies thrust to the outside of the lift arm through the inner lug, and corresponds to the weld seam where the beam is welded to the lift arm The tensile stress to the outside of the lifting arm is generated at the place, and the tensile stress may cause cracking of the welding seam between the lifting arm and the beam, which will affect the performance of the machine
