Description

Technical Field

[0001] This utility model belongs to the field of loader bucket technology, specifically relating to a loader bucket unloading device. Background Technology

[0002] In loader operations, the bucket is the core working device, commonly used for loading and transporting materials. However, the shovel teeth, as vulnerable parts that directly contact the material, require frequent replacement. Traditional bucket structures have limited effectiveness in clearing residual material, and the teeth are often fixed with multiple bolts, requiring individual loosening or tightening during replacement. This cumbersome, time-consuming, and labor-intensive operation severely impacts equipment efficiency and maintenance convenience. Therefore, a new unloading device for loader buckets is urgently needed.

[0003] A patent with publication number CN221681952U discloses an excavator bucket, which includes a bucket body, lead screws, toothed plates, protrusions, tie rods, T-blocks, connecting plates, and toothed buckets. When the toothed bucket needs to be replaced, rotating the lead screws on both sides moves the corresponding toothed plates, separating them from the protrusions. Then, pulling the tie rods moves the T-blocks, moving the toothed plates away from the protrusions. At this point, the connecting plate can be moved to the outside of the bucket body to disassemble the toothed bucket.

[0004] However, the above solution is not convenient enough for the replacement of the toothed bucket. When disassembling the toothed bucket, it is necessary to operate the lead screws and T-blocks on both sides separately. The steps are cumbersome and the operation is complicated. This not only increases the labor intensity of the workers, but also reduces the replacement efficiency, which is not conducive to its promotion and application in actual operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1-7 As shown, the technical solution adopted by this utility model is as follows: a loader bucket unloading device includes a bucket body 1 and a shovel tooth 6. An mounting block 5 is fixedly installed on the bucket body 1, and a connecting plate 8 is fixedly installed on the shovel tooth 6. An opening is provided on one side of the mounting block 5, and the connecting plate 8 can be inserted from the opening side of the mounting block 5.

[0029] Several positioning blocks 14 are fixedly installed inside the mounting block 5, and several positioning slots 25 are opened on the connecting plate 8; the number of positioning blocks 14 and positioning slots 25 are equal and correspond one-to-one, and each positioning block 14 is engaged with the corresponding positioning slot 25.

[0030] The mounting block 5 has a first shaft 9 that rotates horizontally and two sliders 12 that slide and limit in the horizontal direction. Both sliders 12 are slidably fitted onto the outer surface of the first shaft 9 and slide towards or away from each other.

[0031] The mounting block 5 is provided with an adjustment component that acts on the first shaft 9. A transmission component is provided between the first shaft 9 and the two sliders 12. The two sliders 12 are connected to the two ends of the connecting plate 8 in a one-to-one transmission engagement. A protrusion 10 is fixedly provided on the outer surface of the first shaft 9. The protrusion 10 is connected to the top of the connecting plate 8 in a transmission abutment engagement.

[0032] Furthermore, a groove 7 is provided on the top inner wall of the mounting block 5 for the slider 12 to slide.

[0033] Specifically, the first outer cover 11 and the second outer cover 16 are fixedly installed at both ends of the mounting block 5, and the adjustment component is installed on the second outer cover 16.

[0034] Specifically, the adjustment assembly includes a threaded sleeve 17, through which the threaded sleeve 17 is threaded on the side wall of the second outer cover 16. One end of the first shaft 9 extends rotatably into the second outer cover 16 and is splinedly connected to the threaded sleeve 17. The threaded sleeve 17 can not only adjust the rotation angle of the first shaft 9, but also lock the adjusted rotation angle of the first shaft 9 by means of the threaded engagement.

[0035] More specifically, the outer surface of the nut of the threaded sleeve 17 is integrally fixed with a rubber anti-slip sleeve.

[0036] Specifically, the transmission component includes a second shaft 18, which is rotatably mounted in the mounting block 5 in the horizontal direction. The outer surface of the second shaft 18 is fixedly provided with a first thread 22 and a second thread 23 with opposite threads. The first thread 22 and the second thread 23 are both threadedly engaged with the corresponding slider 12.

[0037] The other end of the first shaft 9 extends rotatably into the first outer cover 11 and is fixedly fitted with the first pulley 21. One end of the second shaft 18 extends rotatably into the first outer cover 11 and is fixedly fitted with the second pulley 19. A belt 20 is fitted between the first pulley 21 and the second pulley 19 for transmission.

[0038] Specifically, a number of limiting blocks 15 are fixedly arranged on the outer surface of the slider 12, and a number of limiting grooves 13 are opened at the end of the connecting plate 8 to be engaged with the limiting blocks 15.

[0039] In addition, the bucket body 1 is equipped with a material pushing component.

[0040] Specifically, the material pushing assembly includes a servo electric cylinder 24, a scraper 4 is slidably and limitly installed inside the bucket body 1 along the horizontal direction, the servo electric cylinder 24 is fixedly installed on the outer surface of the bucket body 1, and the telescopic shaft of the servo electric cylinder 24 is fixedly connected to the scraper 4.

[0041] More specifically, a protective cover 2 is fixedly installed on the outer surface of the bucket body 1, and the servo electric cylinder 24 is located inside the protective cover 2.

[0042] A connecting lug 3 is fixedly installed on the top of the bucket body 1.

[0043] It should be noted that the accompanying drawings in this application are all structural schematic diagrams, and their specific sizes may be adjusted according to actual use.

[0044] Working principle: When installing the shovel teeth 6, the operator first needs to slightly lift the connecting plate 8 so that it is higher than the top of the positioning block 14, thereby avoiding the positioning block 14 from obstructing the insertion path of the connecting plate 8. Then, after smoothly inserting the connecting plate 8 from the opening side of the mounting block 5, the connecting plate 8 is lowered, so that the several positioning blocks 14 in the mounting block 5 are precisely engaged in the corresponding positioning grooves 25 on the connecting plate 8, completing the initial limiting and positioning.

[0045] Subsequently, the operator rotates the threaded sleeve 17, and the rotation of the threaded sleeve 17 drives the first shaft 9 to rotate synchronously through the spline connection.

[0046] Rotation of the first shaft 9 causes the protrusion 10 fixed on the first shaft 9 to rotate, thereby gradually pressing the top of the connecting plate 8 and achieving downward pressing and fixing of the connecting plate 8.

[0047] Meanwhile, as the first shaft 9 rotates, the first pulley 21 at one end drives the second pulley 19 to rotate via the belt 20, which in turn drives the second shaft 18 to rotate. The second shaft 18, through the transmission of the first thread 22 and the second thread 23, causes the two sliders 12 to slide towards each other under the limitation of the slide groove 7 until the limiting block 15 on the slider 12 is inserted into the limiting groove 13 on both sides of the connecting plate 8, so as to finally clamp and lock the connecting plate 8.

[0048] The disassembly process is the opposite. By rotating the threaded sleeve 17 in the opposite direction, all locks can be released simultaneously, and the connecting plate 8 can be lifted to separate it from the positioning block 14 and then pulled out.

[0049] In addition, when the bucket body 1 needs to clean up the residual material inside, the servo electric cylinder 24 can be activated to drive the scraper 4 to move along the bottom of the bucket and push the material out, so as to achieve rapid unloading and cleaning.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
