Description

Technical Field

[0001] This utility model relates to the field of loader equipment technology, and in particular to a loader linkage structure and a loader. Background Technology

[0002] A loader is a type of construction machinery used for loading, conveying, and stockpiling loose soil, stones, mud, or other materials. It is widely used in construction, road, bridge, tunnel, and mining projects. The main components of a loader include the chassis, cab, engine, hydraulic system, control system, and working device. The working device is typically a bucket, which can be raised, lowered, and tilted via the hydraulic system to load and unload materials. Traditional loaders are heavy and inflexible in operation, resulting in excessive energy consumption when digging materials and low work efficiency.

[0003] Therefore, in order to address the above problems, a loader linkage structure and a loader are proposed to solve these problems. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a loader linkage structure and a loader. This invention enables loader operations and improves the loader's flexibility.

[0005] The technical solution to the technical problem solved by this utility model is as follows: a loader linkage structure, including a bucket, a power arm connected to the bucket, a rocker arm connected to the power arm, a tie rod connected to the rocker arm, a tie rod connected to the bucket, a first hydraulic cylinder connected to the power arm, and the first hydraulic cylinder being mounted on the vehicle body.

[0006] The first hydraulic cylinder drives the power arm to move, which in turn lifts the bucket. The rocker arm is connected to the tie rod, and the tie rod is connected to the bucket. The movement of the rocker arm drives the movement of the tie rod, thereby adjusting the angle of the bucket and improving the loader's flexibility.

[0007] Preferably, the rocker arm includes an arm plate, a first connecting plate, a second connecting plate, a through hole, and a mounting sleeve. The arm plates are symmetrically arranged and connected to each other by the first connecting plate and the second connecting plate. The middle parts of the symmetrically arranged arm plates are connected by the mounting sleeve, and through holes are provided at both ends of the arm plate.

[0008] The arms are connected by a first connecting plate and a second connecting plate, which improves the overall structural strength of the rocker arm, while reducing the weight of the rocker arm and reducing kinetic energy loss.

[0009] Preferably, a tie rod is provided in the middle of the symmetrically arranged arm plates. The tie rod is rotatably connected to a through hole at one end of the rocker arm, and the through hole at the other end of the rocker arm is connected to a second hydraulic cylinder. The second hydraulic cylinder is mounted on a hinge seat, which is mounted on the power arm.

[0010] The second hydraulic cylinder is connected to the rocker arm through a through hole, causing the rocker arm to rotate. The second hydraulic cylinder is hinged to the hinge seat, which does not affect the rotation of the second hydraulic cylinder.

[0011] Preferably, a mounting base is provided on the bucket, and a connecting shaft is provided on the mounting base, with the connecting shaft rotatably connected to the tie rod.

[0012] Preferably, the boom includes a support plate, a boom crossbeam, a mounting platform, a support shaft, and retaining rings. Support plates are symmetrically arranged at both ends of the boom crossbeam, a mounting platform is arranged on the boom crossbeam, retaining rings are symmetrically arranged on the mounting platform, and a mounting sleeve is arranged in the middle of the symmetrically arranged retaining rings. The support shaft passes through the retaining rings and the mounting sleeve.

[0013] The symmetrically arranged retaining rings have a mounting sleeve in the middle, which facilitates the installation and positioning of the mounting sleeve and reduces lateral sway of the mounting sleeve. The support plates on both sides are connected by the boom cantilever beam, which improves the stability of the equipment.

[0014] Preferably, one end of the boom is rotatably connected to the mounting plate, and the other end of the boom is rotatably connected to the support frame. The mounting plate is symmetrically arranged on the bucket, and the support frame is symmetrically arranged on the front frame.

[0015] The bucket is symmetrically equipped with mounting plates to facilitate connection between the bucket and the boom, and the boom is connected to the support frame to provide support for the boom.

[0016] A loader includes a loader linkage structure; it also includes a rear frame on which a counterweight is mounted.

[0017] The loader uses counterweights to balance the overall weight, making the loader more stable when lifting.

[0018] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0019] The first cylinder drives the power arm to move, which in turn drives the bucket to lift. The rocker arm is connected to the tie rod, and the tie rod is connected to the bucket. By moving the rocker arm, the tie rod moves, thereby adjusting the angle of the bucket and improving the loader's flexibility.

[0020] The arm plates are connected by a first connecting plate and a second connecting plate, which improves the overall structural strength of the rocker arm, reduces the weight of the rocker arm, improves the overall lightweighting of the equipment, reduces the weight of the whole machine, reduces energy loss, and improves fuel economy.
