Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a novel excavator bucket device with adjustable width. Background Technique

[0002] Among construction machinery, a type of ditch operation excavator is designed specifically for excavation operations in narrow and complex environments. They are compact in size and highly maneuverable, capable of easily entering and efficiently completing tasks such as ditch excavation, widening, and cleaning. Ditch operation excavators incorporate advanced hydraulic transmission, precise control, and efficient power systems. It drives the hydraulic system through a powerful engine to achieve precise excavation and operation control. Key components such as the bucket and the boom are made of high-strength materials to ensure stability and durability under complex working conditions. At the same time, with the development of intelligent technology, modern ditch excavators are also equipped with advanced monitoring and control systems, improving construction efficiency and safety. These technical backgrounds have jointly promoted the wide application of ditch excavators in fields such as water conservancy, agriculture, and municipal engineering.

[0003] In ditch excavation and cleaning operations, the fixed-width design of traditional excavator buckets has become a major bottleneck. Due to the variable width of ditches, the situation where the bucket does not match the ditch width often occurs. This not only leads to the need for frequent adjustment of the excavation position during the operation, increasing the necessity of multiple operations, but also results in low overall operation efficiency. More seriously, in order to deal with ditches of different widths, the traditional method often requires changing the bucket, and this process is both complex and time-consuming, further reducing work efficiency and increasing operation costs.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-6 , the present invention provides a technical solution: a novel adjustable-width excavator bucket device, including a bucket body 1, the bucket body 1 includes a bucket box 1.1, bucket teeth 1.2 provided at the front end of the bottom of the bucket box 1.1, and an arm connection bracket 1.3 fixed to the top of the bucket box 1.1. Among them, the top and bottom ends of the bucket box 1.1 are respectively provided with a forward-extending top plate 1.4 and an extension plate 1.5, the bucket teeth 1.2 are fixed to the front end of the extension plate 1.5, the front part of the arm connection bracket 1.3 is fixed to the top surface of the top plate 1.4, and slots 1.6 are respectively provided between the two side walls of the top plate 1.4 and the extension plate 1.5. The front walls on both sides of the bucket box 1.1 are respectively provided with a first clamping groove 1.7.

[0026] The telescopic wall assembly 2 includes a side wall plate 2.1 and insertion plates 2.2 fixed to the top and bottom ends of the inner side wall of the side wall plate 2.1, and the insertion plates 2.2 are respectively inserted into the slots 1.6. A second clamping groove 2.1.1 is provided vertically along the inner side of the rear end of the side wall plate 2.1.

[0027] The two sides of the connecting plate 3 are respectively slidably clamped and matched with the first clamping groove 1.7 and the second clamping groove 2.1.1.

[0028] In summary, when a smaller excavation width is required, the insertion plates 2.2 are completely inserted into the slots 1.6, so that the top and bottom ends of the inner side wall of the side wall plate 2.1 are abutted against the two side walls of the top plate 1.4 and the extension plate 1.5.

[0029] When a wider excavation width is required, the insertion plate 2.2 is pulled outwards along the slot 1.6, and both sides of the connecting plate 3 are respectively inserted into the first slot 1.7 and the second slot 2.1.1 correspondingly. At this time, the connecting plate 3 is in an inclined state, which will reduce the pressure on the connecting plate 3 during excavation, so as to enhance its service life.

[0030] In order to increase the connection strength between the telescopic wall assembly 2 and the bucket body 1 and enhance the stability of the overall structure, multiple groups of positioning through holes 1.8 are respectively arranged horizontally on the top plate 1.4 and the extension plate 1.5, and positioning through holes 2.2.1 corresponding to the positioning through holes 1.8 are arranged on the insertion plate 2.2. The positioning bolts 4 are jointly inserted into the corresponding positioning through holes 1.8 and positioning through holes 2.2.1. That is, when the insertion plate 2.2 is inserted into the slot 1.6 or the insertion plate 2.2 is pulled outwards, it is ensured that the positioning through holes 2.2.1 are aligned with the corresponding positioning through holes 1.8, and then the positioning bolts 4 are used for fixed connection, which not only ensures the overall structural strength, but also is convenient for quick disassembly and assembly, so as to achieve the effect of flexibly and efficiently adjusting the excavation width.

[0031] In order to facilitate the side wall plate 2.1 to better cut into the soil during excavation and effectively extend its service life, the side wall plate 2.1 is a parallelogram steel plate, and a cutting edge is provided on the front side of the side wall plate 2.1. That is, this structure not only facilitates cutting into the soil, but also can reduce the pressure on the side wall plate 2.1 during excavation.

[0032] Specifically, both the first slot 1.7 and the second slot 2.1.1 are cylindrical grooves opening along the axial direction, and the bottom end of the cylindrical groove is a closed structure. The connecting plate 3 includes a steel plate 3.1 and round rods 3.2 fixed on both sides of the steel plate 3.1 and inserted and matched with the first slot 1.7 and the second slot 2.1.1.

[0033] In order to prevent the connecting plate 3 from moving upwards during use, limiting members 5 for positioning the top end of the connecting plate 3 are respectively detachably fixed on both sides of the top surface of the bucket box 1.1 and at the position near the rear end of the top surface of the side wall plate 2.1. Among them, a first positioning screw hole 1.9 is provided at the position inside the top end of the first slot 1.7 on the top surface of the bucket box 1.1, and a second positioning screw hole 2.1.2 is provided at the position in front of the top end of the second slot 2.1.1 on the top surface of the side wall plate 2.1. The limiting member 5 includes a blocking plate 5.1 and fixing screws 5.2 sleeved on one end of the blocking plate 5.1 and threadedly sleeved and matched with the first positioning screw hole 1.9 and the second positioning screw hole 2.1.2. That is, after the whole connecting plate 3 is installed and the round rods 3.2 on both sides are exactly completely inserted into the corresponding cylindrical grooves, at this time, the blocking plate 5.1 is placed on the top end of the round rod 3.2 and the fixing screws 5.2 are screwed into the first positioning screw hole 1.9 and the second positioning screw hole 2.1.2, so as to firmly press the top end of the round rod 3.2, achieving the effect of preventing the connecting plate 3 from slipping upwards.
