Description

Technical Field

[0001] This invention belongs to the field of engineering machinery technology, and in particular relates to a multi-condition bucket and excavator. Background Technology

[0002] Excavators, as a typical representative of construction machinery, have a wide range of operations and complex working conditions. In daily construction operations, excavators perform tasks such as digging, loading, and demolition. The bucket is the direct working attachment of the excavator, and its main functions are digging and loading. Its function is singular, and when changing working conditions, the corresponding bucket must be changed. For example, for material filtration operations, a grid bucket needs to be used, but a grid bucket cannot be used for earthmoving.

[0003] Although quick-change buckets are now available, offering buckets for various purposes, allowing for bucket replacement under different working conditions, for filtering materials, a grid bucket needs to be replaced, and after screening, a regular bucket needs to be replaced for loading. This requires configuring buckets for at least two different purposes, and the bucket replacement process undoubtedly increases operating costs and time, reducing work efficiency. Summary of the Invention

[0010] Optionally, the drive assembly includes a telescopic rod disposed on the top plate, a limiting groove communicating with the sliding groove on the top plate, a connector disposed at the telescopic end of the telescopic rod, the connector passing through the limiting groove and being connected to the sliding beam, the connector being slidably connected to the limiting groove, and the limiting groove being used to limit the sliding stroke of the connector.

[0011] Optionally, among the several outer ribs, the outer rib closest to the side plate is the edge outer rib, the edge outer rib is connected to the side plate, the outer rib between two edge outer ribs is the middle outer rib, and multiple middle outer ribs are evenly arranged between two edge outer ribs.

[0012] Optionally, the inner rib includes a left inner rib and a right inner rib, and the sliding beam includes a first sliding beam and a second sliding beam. The right inner rib is arranged on the first sliding beam, and the left inner rib is arranged on the second sliding beam. A right inner rib is arranged in the outer edge rib on the left side, and a left inner rib is arranged in the outer edge rib on the right side. Each of the middle outer ribs has a left inner rib and a right inner rib. The size of a grid hole is adjusted by the cooperation of the left and right ribs on both sides. The driving assembly is used to drive the first sliding beam and the second sliding beam to slide synchronously in opposite directions.

[0013] Optionally, the drive assembly includes a telescopic rod mounted on a top plate, a limiting groove communicating with the sliding groove on the top plate, a connecting member at the telescopic end of the telescopic rod, the connecting member passing through the limiting groove and connecting to the first sliding beam, the connecting member slidingly connected to the limiting groove, the limiting groove being used to limit the sliding stroke of the connecting member; a transmission device is provided between the first sliding beam and the second sliding beam, the transmission device being used to make the first sliding beam and the second sliding beam slide synchronously in opposite directions.

[0014] Optionally, the transmission device includes a gear, a first tooth groove is provided on the first sliding beam, and a second tooth groove is provided on the second sliding beam, wherein the gear is meshed with both the first tooth groove and the second tooth groove.

[0020] Compared with the prior art, this application has at least the following beneficial effects:

[0021] This invention connects an inner rib plate to the outer rib plate by sliding within it. The sliding of the inner rib plate allows for adjustment of the grid hole opening size or closure of the grid holes. This enables the bucket to be used for both loading and filtering materials. The grid hole size is adjustable to meet the filtration requirements of different particle sizes. The bucket can meet various working conditions and avoids the hassle of changing buckets.

[0022] In this invention, the size of a grid hole is adjusted by the synchronous, opposite movement of the left and right ribs on both sides, ensuring that the grid hole is always positioned between the two outer ribs. This ensures uniform stress on the outer ribs during use, avoiding wear and deformation caused by uneven weight distribution. By ensuring that the combined width of the left and right inner ribs is greater than the width of the grid hole, a partial overlap between the outer and inner ribs is maintained. This allows for smooth sliding of the inner ribs and ensures uniform stress on the outer ribs, improving their load-bearing capacity. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0036] Example 1

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

[0038] Multiple outer ribs 4 are arranged between the two side plates 3. The number of outer ribs 4 can be determined according to the actual situation. 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 grid hole is formed between adjacent outer ribs 4. An installation cavity is opened on the outer rib 4. An inner rib 5 is arranged in the installation cavity and is slidably connected to the outer rib 4. The inner rib 5 is used to adjust the size of the grid hole opening or to close the grid hole.

[0039] Several support rods 6 are provided between the two side plates 3. The support rods 6 pass through the inner rib plate 5 and are slidably connected to the inner rib plate 5. A drive assembly 7 for driving the inner rib plate 5 to slide is provided on the top plate 1.

[0040] The drive assembly 7 drives the inner rib plate 5 to slide along the support rod 6. The inner rib plate 5 can block some or all of the grid holes. When the grid holes are completely closed, the bucket can be used for loading. When the grid holes are partially closed or not closed, filtering can be carried out through the grid holes on its upper part. Thus, the bucket can be easily converted into various forms, which can be conveniently adapted to various working conditions and avoid the tediousness of changing 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 provided on the top plate 1, and a sliding beam 12 is slidably connected in the sliding groove 11. The inner rib plate 5 extends out of the mounting cavity towards the top plate 1 and is connected to the sliding beam 12. The sliding beam 12 can be driven to slide by the driving component 7.

[0043] The drive assembly 7 includes a telescopic rod 71 mounted on the top plate 1. The telescopic rod 71 can be a hydraulic cylinder or any other telescopic rod. The top plate 1 has a limiting groove 721 that communicates with the sliding groove 11. The telescopic end of the telescopic rod 71 is provided with a connector 72. The connector 72 passes through the limiting groove 721 and is connected to the sliding beam 12. The sliding beam 12 has a threaded hole 123 for connecting with the connector 72. The connector 72 is slidably connected to the limiting groove 721. The telescopic rod 71 extends and retracts, causing the connector 72 and the sliding beam 12 to move. The sliding beam 12 carries the inner rib plate 5 and slides along the support rod 6, thereby adjusting the size of the grid holes. The limiting groove 721 is used to limit the sliding stroke of the connector 72.

[0044] The inner rib plate 5 is fixed to the sliding beam 12 by screws. The top plate 1 has a mounting hole 13 on the side opposite to the sliding groove 11. The mounting hole 13 is connected to the sliding groove 11. The mounting hole 13 is used to install the inner rib plate 5 on the sliding beam 12. In order 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 plate 5. When the inner rib plate 5 is installed to the sliding beam 12 in the sliding groove 11, it cannot be installed without the mounting hole 13. The sliding beam 12 is provided with through screw holes that are compatible with bolts. The inner rib plate 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 rib plate 4 near the side plate 3 is the edge outer rib plate 4, the edge outer rib plate 4 is connected to the side plate 3, the outer rib plate 4 between the two edge outer rib plates 4 is the middle outer rib plate 4, and multiple middle outer rib plates 4 are evenly arranged between the two edge outer rib plates 4, thereby improving the structural stability and the uniformity of force.

[0047] like Figure 6-7 As shown, the inner rib 5 includes a left inner rib and a right inner rib, and the sliding beam 12 includes a first sliding beam 121 and a second sliding beam 122. The right inner rib is arranged on the first sliding beam 121 via a first mounting block 1211, and the left inner rib is arranged on the second sliding beam 122 via a second mounting block 1221. A right inner rib is arranged in the left edge outer rib 4, and a left inner rib is arranged in the right edge outer rib 4. Each middle outer rib 4 has a left inner rib and a right inner rib. The size of a grid hole is adjusted by the cooperation of the left and right ribs on both sides. The drive assembly 7 is used to drive the first sliding beam 121 and the second sliding beam 122 to slide synchronously in opposite directions. Driven by the drive assembly 7, the first sliding beam 121 and the second sliding beam 122 slide in opposite directions simultaneously. The size of the grid hole is adjusted by the combined action of the right rib and the left rib on both sides of the grid hole. The movement of the left rib and the right rib is synchronous, which ensures that the grid hole is always in the middle position of the two outer ribs 4, maintains uniform force, and avoids damage to one side of the outer rib 4 due to uneven force.

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

[0049] The combined width of the left inner rib and the right inner rib is greater than the width of the grid hole, thus ensuring that there is a 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 not hollow, so that the force is evenly distributed.

[0050] When the telescopic rod 71 is shortened, the first sliding beam 121 slides under the drive of the connecting piece 72, causing the right rib to slide to the right. Through the meshing of the gear 731 with the first tooth groove 732 and the second tooth groove 733, the second sliding beam 122 drives the left rib to slide to the left synchronously, thereby facilitating the adjustment of the grid holes by the cooperation of the right and left ribs on both sides of the grid holes.

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

[0052] Figure 9 When the telescopic rod 71 is at its shortest length under the limiting groove 721, the grid holes are completely closed, so that it can be used as an earthmoving bucket. At this time, the inner rib plate 5 and the outer rib plate still have a part of overlap.

[0053] Example 4

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

[0055] An excavator includes the aforementioned multi-function bucket.
