Description

Technical Field

[0001] This utility model relates to an excavator, and more specifically, to an excavator and its bucket. Background Technology

[0002] To maintain high efficiency when handling different materials, excavators are typically equipped with buckets of varying capacities. While excavator buckets are usually of fixed capacity, loading operations often involve handling different materials, such as loose soil, earth and rock, and blasted rock, thus requiring different bucket capacities. To address this need, some excavators employ a "one machine, multiple buckets" configuration, but this solution is costly.

[0003] To address varying bucket capacities, some excavator buckets employ variable capacity designs. For instance, Chinese patent document CN 211646517 U discloses an excavator bucket with extension plates detachably connected to both sides of the main body plate. A sealing plate is detachably connected to the side of the extension plate away from the main body plate, and the sealing plate is detachably connected to the main body plate when the extension plate is detached. While this design allows for bucket capacity adjustment by adding or removing extension plates, the process is cumbersome and inconvenient for frequent switching during operation. Chinese patent document CN112281948A discloses an excavator bucket with adjustable capacity, comprising a bucket body and a bottom cover, hinged at their lower ends for rotation. Rotating the bottom cover forward decreases the bucket capacity, while rotating it backward increases it. This type of bucket has a complex structure and significantly impacts its strength.

[0027] The specific implementation plan is described below with reference to the attached diagram.

[0028] The excavator bucket includes a bucket body, which includes a bucket side plate 1 and a bucket bottom plate 2. The excavator bucket also includes multiple height-increasing baffles, each of which is arranged above the rear end of the bucket side plate 1 and the bucket bottom plate 2. The lower part of the height-increasing baffle is detachably and fixedly connected to the upper edge of the corresponding bucket side plate and the upper edge of the bucket bottom plate by fasteners 5.

[0029] The bucket body can realize the function of a bucket. It includes a U-shaped bucket bottom plate 2, two bucket side plates 1 are set at both ends of the bucket bottom plate 2 to form a bucket-shaped structure, bucket teeth are installed at the front end of the bucket bottom plate 2, and a hinge seat is installed on the rear side of the bucket bottom plate 2 for connecting with the excavator's stick.

[0030] like Figure 1 As shown, in this embodiment, the height-increasing baffle includes a side height-increasing baffle 3 and a rear height-increasing baffle 4. The side height-increasing baffle 3 is installed on the upper edge of the bucket side plate 1, and the rear height-increasing baffle 4 is installed on the rear end of the bucket bottom plate 2. The side height-increasing baffle 3 and the rear height-increasing baffle 4 are correspondingly installed at the rear ends of the bucket side plate 1 and the bucket bottom plate 2, which is equivalent to increasing the height of the rear ends of the bucket side plate 1 and the bucket bottom plate 2, thereby increasing the bucket capacity. The height-increasing baffle is detachably fixed to the bucket body. After the height-increasing baffle is removed, the bucket body constitutes a bucket with a relatively small capacity but complete functions.

[0031] Optionally, the rear end of the heightening baffle located above the bucket side plate 1 and the heightening baffle located above the bucket bottom plate 2 are detachably fixedly connected or hinged. The bucket side plate 1 and the bucket bottom plate 2 are perpendicular to each other, and the side heightening baffle 3 and the rear heightening baffle 4 are also perpendicular to each other. Connecting the perpendicular side heightening baffle 3 and the rear heightening baffle 4 can improve their load-bearing capacity. The side heightening baffle 3 and the rear heightening baffle 4 can be fixedly connected, for example, by welding them together, or they can be detachably fixedly connected, for example... Figure 1The side heightening baffle 3 is provided with a connecting ear plate 31 at its rear end. After both the side heightening baffle 3 and the rear heightening baffle 4 are installed, the connecting ear plate 31 on the side heightening baffle 3 fits into the rear heightening baffle 4. The connecting ear plate 31 and the rear heightening baffle 4 are locked and fixedly connected by a bolt assembly, so that the side heightening baffle 3 and the rear heightening baffle 4 can be fixedly connected.

[0032] The side height-increasing baffle 3 and the rear height-increasing baffle 4 can also be hinged. Before installation, the side height-increasing baffle 3 and the rear height-increasing baffle 4 can rotate relative to each other around the hinge pin. After installation and fixing, the side height-increasing baffle 3 and the rear height-increasing baffle 4 are relatively fixed.

[0033] The rear liftgate 4 can be a single piece, extending from one side of the bucket body to the other, or it can be two pieces, such as... Figure 1 As shown, two rear extension baffles 4 are installed at intervals on both sides of the hinge support. The installation of two rear extension baffles 4 at intervals can prevent the rear extension baffles 4 from interfering with the excavator stick.

[0034] Optionally, a blade structure 32 is provided on the upper edge of the heightening baffle located above the side plate 1 of the bucket, that is, a blade structure 32 is provided on the upper edge of the side heightening baffle, such as... Figure 2 As shown, the blade structure 32 can improve the cutting force during bucket digging operations. Additionally, the front end of the side riser baffle 3 is provided with a guide ramp 33 that gradually rises backward; the guide ramp 33 can reduce the resistance during bucket digging operations.

[0035] Optionally, the lower edge of the heightening baffle is provided with a slot 34 for the corresponding upper edge of the bucket side plate 1 and the bucket bottom plate 2 to be inserted. For example... Figure 1 Figure 4 As shown, a slot 34 is provided at the lower edge of the side riser baffle 3, and the upper edge of the bucket side plate 1 is embedded in the slot 34 at the lower edge of the side riser baffle 3. The side riser baffle 3 and the bucket side plate 1 are then connected by fasteners 5. The fasteners 5 can be bolt assemblies or a combination of a pin 51 and a retaining ring 52, such as... Figure 3 Figure 4As shown. Fastener 5 includes a pin 51 and a retaining ring 52. The pin 51 is provided with an annular groove 53 that matches the retaining ring 52. The side wall of the retaining groove 34 of the side riser 3 and the upper edge of the corresponding bucket side plate 1 and bucket bottom plate 2 are provided with pin holes for accommodating the pin. One end of the pin holes on the bucket side plate 1 and bucket bottom plate 2 is provided with a countersunk hole 13 for accommodating the retaining ring. The pin hole on the bucket side plate 1 is a first pin hole 12, and the pin hole on the side riser 3 is a second pin hole 35. The first pin hole 12 and the second pin hole 35 correspond one-to-one and are coaxially arranged to accommodate the pin 51. One end of the first pin hole 12 is provided with a countersunk hole 13, which is used to accommodate the retaining ring 52. The outer diameter of the retaining ring 52 is larger than the diameter of the second pin hole 35. When the side heightening baffle 3 is connected to the bucket side plate 1, the retaining ring 52 is placed in the countersunk hole 13, and then the upper edge of the bucket side plate 1 is embedded into the retaining groove 34. The pin 51 is inserted into the coaxially aligned first pin hole 12 and second pin hole 35, and the retaining ring 52 is engaged with the annular groove 53 on the pin. The retaining ring 52 and the annular groove 53 cooperate to prevent the pin 51 from moving axially and falling off.

[0036] Optionally, multiple limiting blocks 11 are provided at intervals along the side of the bucket side plate 1 along its length, such as... Figure 1 As shown, the lower edge of the side heightening baffle 3 is provided with a limiting groove 36 for the corresponding limiting block to be inserted. Preferably, the limiting blocks 11 are arranged on the inner and outer sides of the upper edge of the bucket side plate 1 and the bucket bottom plate 2, and the limiting blocks on the inner and outer sides are arranged in a mirror-symmetric manner. The limiting blocks 11 cooperate with the limiting groove 36 to increase the load on the side heightening baffle 3 in the vertical direction (height direction of the side heightening baffle 3) and the horizontal direction (front and rear direction of the side heightening baffle 3).

[0037] The structure at the bottom of the side height-increasing baffle 3 can also be in other styles, such as... Figure 5 Figure 6 As shown, the lower edge of the side heightening baffle 3 is provided with a step 37. When the side heightening baffle 3 is connected and installed with the bucket side plate 1, the upper edge of the bucket side plate 1 is attached to the step 37 at the lower edge of the side heightening baffle 3, and then locked and fixed by bolts and nuts.

[0038] The connection structure between the rear heightening baffle 4 and the bottom plate 2 is the same as the connection structure between the side heightening baffle 3 and the side plate 1.

[0039] This embodiment also provides an excavator having the aforementioned excavator bucket.

[0040] In this embodiment, the height-increasing baffle is an independent and detachable device that does not damage the original structure of the bucket. The capacity-enhancing structure is similar to the original bucket side plate guard teeth, and the mounting components can be interchanged without affecting the original performance of the bucket. No power unit is required, resulting in low failure risk and convenient maintenance and replacement. The height-increasing baffle features a lightweight design, facilitating installation and replacement, while adding minimal weight to the bucket after installation.
