[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0036] Example 1

[0037] like Figure 1-2 As shown, a multi-working bucket includes a bucket main frame 8, the bucket main frame 8 includes a top plate 1, a main blade plate 2 and two side plates 3 arranged on both sides of the top plate 1, and the two ends of the main blade plate 2 are respectively connected to the two side plates 3;

[0038] A plurality of outer ribs 4 are arranged between the two side plates 3, and the number of the outer ribs 4 can be determined according to actual conditions. One end of the outer rib 4 is connected to the top plate 1, and the other end is connected to the main blade plate 2. A grille hole is formed between the adjacent outer ribs 4. An installation cavity is provided on the outer rib 4, and an inner rib 5 slidably connected to the outer rib 4 is arranged in the installation cavity. The inner rib 5 is used to adjust the opening size of the grille hole or close the grille hole.

[0039] A plurality of support rods 6 are arranged between the two side plates 3 , and the support rods 6 are passed through the inner ribs 5 , and the inner ribs 5 are slidably connected to the support rods 6 ; a driving assembly 7 for driving the inner ribs 5 to slide is arranged on the top plate 1 .

[0040] The driving assembly 7 drives the inner ribs 5 to slide along the support rods 6. The inner ribs 5 can cover part or all of the grille holes. When all the grille holes are closed, the bucket can be used for loading. When the grille holes are partially closed or not closed, filtering can be performed through the grille holes thereon. Thus, the bucket can be conveniently converted between various forms, conveniently adapting to various working conditions, and avoiding the tediousness of replacing the bucket.

[0041] Example 2

[0042] like Figure 3-5 As shown, the difference between this embodiment and embodiment 1 is that a sliding groove 11 is opened on the top plate 1, and a sliding beam 12 is slidingly connected in the sliding groove 11, and the inner rib 5 extends out of the installation cavity toward one end of the top plate 1 and is connected to the sliding beam 12, and the driving component 7 can be used to drive the sliding beam 12 to slide.

[0043] The driving assembly 7 includes a telescopic rod 71 installed on the top plate 1. The telescopic rod 71 can be a hydraulic cylinder or any other telescopic function. A limiting groove 721 connected to the sliding groove 11 is provided on the top plate 1. A connecting piece 72 is provided at the telescopic end of the telescopic rod 71. The connecting piece 72 passes through the limiting groove 721 and is connected to the sliding beam 12. The sliding beam 12 is provided with a threaded hole 123 for connecting with the connecting piece 72. The connecting piece 72 is slidingly connected to the limiting groove 721. The telescopic rod 71 is extended and retracted to drive the connecting piece 72 and the sliding beam 12 to move. The sliding beam 12 slides along the support rod 6 with the inner rib plate 5, so that the size of the grille hole can be adjusted. The limiting groove 721 is used to limit the sliding stroke of the connecting piece 72.

[0044] The inner rib 5 is fixed to the sliding beam 12 by screws, and a mounting hole 13 is opened on the side of the top plate 1 away from the sliding groove 11, and the mounting hole 13 is connected with the sliding groove 11. The mounting hole 13 is used to install the inner rib 5 on the sliding beam 12. To facilitate the production of parts, the top plate 1 is integrally formed and then assembled with the sliding beam 12 and the inner rib 5. When the inner rib 5 is installed to the sliding beam 12 in the sliding groove 11, the installation cannot be achieved without the mounting hole 13. The sliding beam 12 is provided with a through screw hole compatible with the bolt, and the inner ribs 5 can be fixed to the sliding beam 12 one by one with bolts through the mounting hole 13.

[0045] Example 3

[0046] The difference between this embodiment and embodiment 2 is that the outer ribs 4 close to the side panels 3 among the outer ribs 4 are edge outer ribs 4, the edge outer ribs 4 are connected to the side panels 3, the outer ribs 4 between the two edge outer ribs 4 are intermediate outer ribs 4, and multiple intermediate outer ribs 4 are evenly arranged between the two edge outer ribs 4, thereby improving the structural stability and uniformity of force.

[0047] like Figure 6-7 As shown, the inner rib plate 5 includes a left inner rib plate and a right inner rib plate, the sliding beam 12 includes a first sliding beam 121 and a second sliding beam 122, the right inner rib plate is arranged on the first sliding beam 121 through a first mounting block 1211, and the left inner rib plate is arranged on the second sliding beam 122 through a second mounting block 1221, a right inner rib plate is arranged in the edge outer rib plate 4 on the left side, a left inner rib plate is arranged in the edge outer rib plate 4 on the right side, a left inner rib plate and a right inner rib plate are arranged in each middle outer rib plate 4, a grille hole is adjusted in size by the cooperation of the left rib plate and the right rib plate on both sides of the grille hole, and the driving assembly 7 is used to drive the first sliding beam 121 and the second sliding beam 122 to slide synchronously in the opposite direction. Driven by the driving assembly 7, the first sliding beam 121 and the second sliding beam 122 slide in opposite directions synchronously, and the right rib plate and the left rib plate on the left and right sides of the grille hole work together to adjust the size of the grille hole. The movement of the left rib plate and the right rib plate is synchronous, thereby ensuring that the grille hole is always in the middle position of the two outer rib plates 4, maintaining uniform force, and avoiding damage to the outer rib plate 4 on one side due to uneven force.

[0048] The driving assembly 7 includes a telescopic rod 71 arranged on the top plate 1, and a limiting groove 721 connected to the sliding groove 11 is opened on the top plate 1. A connecting piece 72 is arranged at the telescopic end of the telescopic rod 71. The connecting piece 72 passes through the limiting groove 721 and is connected to the first sliding beam 121. The connecting piece 72 is slidingly connected to the limiting groove 721, and the limiting groove 721 is used to limit the sliding stroke of the connecting piece 72; a transmission device 73 is arranged between the first sliding beam 121 and the second sliding beam 122, and the transmission device 73 is used to make the first sliding beam 121 and the second sliding beam 122 slide in opposite directions synchronously. The top plate 1 is provided with a mounting groove 730 for mounting the transmission device 73. The transmission device 73 includes a gear 731. The first sliding beam 121 is provided with a first tooth groove 732. The second sliding beam 122 is provided with a second tooth groove 733 (fixed by bolts and fixing screw holes 735). The gear 731 is meshed and connected with the first tooth groove 732 and the second tooth groove 733. The top plate 1 is provided with a protective cover 734. The protective cover 734 is provided on the outer periphery of the transmission device 73. The gear 731 shaft of the gear 731 is fixedly connected with the protective cover 734.

[0049] The sum of the widths of the left inner rib and the right inner rib is greater than the width of the grille hole, thereby ensuring that there is partial overlap between the outer rib 4 and the inner rib 5. On the one hand, the inner rib 5 slides smoothly, and on the other hand, the outer rib 4 is prevented from being hollow, so that the force is evenly distributed.

[0050] The telescopic rod 71 is controlled to shorten, and the first sliding beam 121 slides under the drive of the connecting member 72, driving the right rib plate to slide to the right. Through the meshing action of the gear 731 and the first tooth groove 732 and the second tooth groove 733, the second sliding beam 122 drives the left rib plate to slide to the left synchronously, thereby facilitating the adjustment of the grille hole by the right rib plate and the left rib plate on the left and right sides of the grille hole.

[0051] Figure 8 When the telescopic rod 71 is at its longest length under the limiting groove 721, the inner rib 5 is completely embedded in the outer rib 4, and the grid hole spacing is maximum.

[0052] Fig. 9 When the limit groove 721 is limited and the telescopic rod 71 is at the shortest length, the grille hole is completely closed and can be used as an earthwork bucket. At this time, the inner rib plate 5 and the outer rib plate are still partially overlapped.

[0053] Example 4

[0054] The difference between this embodiment and embodiment 3 is that the transmission device 73 includes a retractable rod arranged on the top plate 1, and the driving end of the retractable rod is connected to the second sliding beam 122 in the same manner as the connection between the telescopic rod 71 and the first sliding beam 121, and the telescopic rod 71 and the retractable rod are retracted synchronously and in opposite directions.
