Description

Technical Field

[0001] This utility model relates to the technical field of loader equipment, specifically an expandable bucket for a loader. Background Technology

[0002] When using a loader to transport materials, the bucket volume is usually fixed. Therefore, in actual operation, a fixed-volume bucket often cannot meet the demand. If too much material is scooped at once, exceeding the bucket's carrying capacity, the material is prone to spillage during transport due to excessive accumulation. This not only wastes materials and increases production costs but may also pollute the work site, affecting cleanliness and subsequent cleanup. Conversely, reducing the scooping volume per trip to avoid spillage lowers the loader's efficiency, prolongs operation time, and fails to meet the demands of high-efficiency production. Utility Model Content

[0003] The purpose of this invention is to provide an expandable bucket for a loader, which solves the problem mentioned in the background art that fixed-volume buckets are prone to spilling materials when shoveling and transporting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an expandable bucket for a loader, comprising a bucket and an expansion mechanism disposed on the bucket, wherein an opening is provided at the tail of the bucket, and the expansion mechanism comprises an expansion plate hinged to the opening and a hydraulic cylinder hinged to the tail of the bucket; the telescopic shaft of the hydraulic cylinder is hinged to the expansion plate, and telescopic plates are provided at both ends of the expansion plate and both ends of the opening.

[0005] Furthermore, the telescopic plate is composed of multiple sector plates; the bottoms of the multiple sector plates are connected to each other by pins.

[0006] Furthermore, an arc-shaped groove is provided on one side of the fan-shaped plate, and a protrusion is provided on the other side of the fan-shaped plate, with the groove and the protrusion being adapted to each other.

[0007] Furthermore, the hydraulic cylinder is specifically a mechanical self-locking hydraulic cylinder.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. Preventing material spillage: This utility model sets up an expansion mechanism at the opening of the bucket tail. When the material in the bucket exceeds a certain amount, the hydraulic cylinder can be controlled to drive the expansion plate and telescopic plate to unfold, thereby expanding the volume of the bucket and effectively preventing material from spilling due to excessive accumulation, thus avoiding material waste and environmental pollution.

[0010] 2. Improve work efficiency: Without increasing the number of times the loader is moved, it can carry more materials, reduce the number of round trips, improve the working efficiency of the loader, shorten the overall operation time, and meet the needs of high-efficiency production.

[0011] 3. Safe and reliable: The hydraulic cylinder has a self-locking function, which can stably maintain the current state after the expansion plate and telescopic plate are extended or retracted, preventing the expansion mechanism from being activated due to unexpected situations, and ensuring the safety and reliability of the operation process.

[0019] Please see Figures 1 to 5 An expandable bucket for a loader comprises a bucket 1 connected to the loader's boom, rocker arm, linkage mechanism, and bucket cylinder, and an expansion mechanism mounted on the bucket 1. An opening 2 is provided at the tail of the bucket 1. This device, by incorporating the expansion mechanism at the opening 2, expands the bucket 1 when material is being moved, preventing material from spilling out due to excessive accumulation.

[0020] Specifically,

[0021] The expansion mechanism consists of an expansion plate 3, a hydraulic cylinder 4, and a telescopic plate 5. A receiving plate is welded to the bottom of the opening 2, and the expansion plate 3 is hinged to the receiving plate by a pin. The hydraulic cylinder 4 has a self-locking function, specifically a hydraulic cylinder with a hydraulic lock or a mechanical self-locking hydraulic cylinder, and is connected to the hydraulic system of the loader, which provides power. The bottom of the hydraulic cylinder 4 is hinged to the tail of the bucket 1 and located below the opening 2, and the output shaft of the hydraulic cylinder 4 is hinged to the expansion plate 3.

[0022] The aforementioned telescopic plate 5 is specifically composed of multiple sector plates 6. Each sector plate 6 has a pin hole at its bottom, and a pin passes through these pin holes to connect the sector plates 6, forming a fan-like structure. An arc-shaped groove 7 is formed on one side of each sector plate 6, and a protrusion 8 is formed on the other side. The protrusion 8 of one sector plate 6 is located within the groove 7 of an adjacent sector plate 6 and can slide within the groove 7 (e.g., ...). Figure 3 , 4 (As shown in Figure 5). The fan-shaped plates 6 located on both sides are connected to the bucket 1 and the expansion plate 3. When all the fan-shaped plates 6 are opened or closed, their bottoms should fit the hinge joints of the expansion plate 3 and the receiving plate to prevent material leakage.

[0023] The aforementioned hydraulic cylinder 4 is connected to the vehicle domain controller, on-board controller, or centralized control unit of the loader to control the start or stop of the hydraulic cylinder 4.

[0024] The working principle of this utility model is as follows: In the initial state, the telescopic shaft of the hydraulic cylinder 4 extends, driving the expansion plate 3 to rotate until it is parallel to the tail of the bucket 1. At this time, the telescopic plate 5 retracts. During operation, the bucket 1 is driven by the boom, rocker arm, linkage mechanism, and other components of the loader to dig materials. After digging is completed and the material needs to be transported to a certain position (at this time, the bucket opening is facing upwards), the operator observes the amount of material in the bucket 1. If there is too much material, the telescopic shaft of the hydraulic cylinder 4 is controlled to retract, which in turn drives the expansion plate 3 to swing to a certain position, causing the telescopic plate 5 to unfold, thereby increasing the volume of the bucket 1 and preventing material spillage.

[0025] After the material is unloaded, the extension shaft of the hydraulic cylinder 4 is extended by the vehicle domain controller, vehicle controller or centralized control unit, thereby driving the expansion plate 3 and extension plate 5 to reset so that the material can be excavated again.
