Description

Technical Field

[0001] The utility model relates to the technical field of loaders, in particular to an auxiliary positioning bucket of a loader. Background Art

[0002] A loader is a type of earthwork construction machinery widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used for shoveling loose materials such as soil, sand, lime, and coal. It can also perform light shoveling and excavation of ore, hard soil, etc. By replacing different auxiliary working devices, it can also perform bulldozing, lifting, and loading and unloading of other materials such as wood. The bucket refers to the bucket installed on the loader, also called a digging bucket. According to the working mode, it is divided into backhoe bucket and front shovel bucket. The backhoe bucket is commonly used.

[0003] At present, when installing the bucket of a loader, a special person is required to direct the installation. Although the loader can be installed by one person, the driver will have a blind spot when installing the bucket due to the obstruction of the loader cantilever. The driver needs to drive the loader back and forth many times for installation. The operation is very troublesome and time-consuming, which seriously affects the construction progress of the project. In addition, the driver drives the loader back and forth many times to install the bucket, which makes the loader cantilever collide with the bucket many times, and in severe cases, the connecting parts between the bucket and the cantilever will bend. Utility Model Content

[0004] The utility model aims to provide a loader auxiliary positioning bucket to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A loader auxiliary positioning bucket comprises a bucket and a mounting plate, a mounting mechanism is arranged between the bucket and the mounting plate, both sides of the two ends of an outer side surface of the bucket are fixedly connected with fixing seats, a mounting rod is fixedly connected between two fixing seats at relative positions, the mounting mechanism comprises four fixing blocks distributed in a rectangular shape and fixed to the mounting plate, one end of the fixing block is rotatably connected with a hook connected to the mounting rod hook at the corresponding position, a trapezoidal block is fixedly connected to the side opposite to the upper and lower hooks, a connecting plate is fixedly connected between the upper and lower fixing seats, a connecting plate is fixedly connected to the two ends of a side surface of the mounting plate, and a hydraulic cylinder is fixedly connected to the side opposite to the two connecting plates.

[0007] Furthermore, four corners of one side of the mounting plate are fixedly connected with hydraulic cylinders 2, a movable plate is fixedly connected between the output ends of the four hydraulic cylinders 2, and two long side edges of one side of the movable plate are both inclined surfaces.

[0008] Furthermore, one end of the hydraulic cylinder 2 is fixedly connected to a connecting pipe which is connected to the inside of the hydraulic cylinder 2 at a corresponding position and passes through the mounting plate, a three-way pipe 2 is fixedly connected between the two connecting pipes at relative positions, a conduit 2 is fixedly connected between the two three-way pipes 2, a three-way pipe 3 which is connected to the inside of the conduit 2 is fixedly connected to the outer wall of the conduit 2, and an oil pipe 2 is fixedly connected to one end of the three-way pipe 3.

[0009] Furthermore, a conduit 1 communicating with the two hydraulic cylinders 1 is fixedly connected between the two hydraulic cylinders 1, a tee pipe 1 is fixedly connected to the outer wall of the conduit 1, and an oil pipe 1 is fixedly connected to one end of the tee pipe 1.

[0010] Furthermore, both sides of the other side of the mounting plate are fixedly connected with mounting seats.

[0011] Furthermore, one end of the oil pipe 1 and the oil pipe 2 are both fixedly connected with a connector.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By starting the two hydraulic cylinders 1, the output ends of the two hydraulic cylinders 1 can be extended. If the mounting plate is slightly biased toward one of the connecting plates, the output end of the hydraulic cylinder 1 near the connecting plate will contact the connecting plate first, and the bucket will move under the action of the hydraulic cylinder 1 until the output ends of the two hydraulic cylinders 1 contact the connecting plates at the corresponding positions respectively. At this time, the mounting plate is positioned in the middle of the four fixing seats, which can prevent the bucket from tilting due to the shift of the center of gravity when shoveling materials;

[0014] 2. The movable plate can be moved by starting the four hydraulic cylinders 2. The moving plate can squeeze the four trapezoidal blocks and make the four trapezoidal blocks rotate along the rotation axis of the hooks at the corresponding positions and the fixed blocks at the corresponding positions until the rotating trapezoidal blocks clamp the hooks at the corresponding positions with the mounting rods at the corresponding positions. At this time, the bucket 1 is fixed on the mounting plate, which facilitates the installation of the bucket, saves installation time, and does not affect the construction progress of the project.
