Description

Technical Field

[0001] The present invention relates to the technical field of loaders, and in particular to a loader bucket. Background Art

[0002] A loader is a type of earthwork construction machinery widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used to shovel bulk materials such as soil, sand, gravel, lime, and coal. The bucket is the main accessory of the loader and is the container used to shovel materials when the loader is operating.

[0003] In the prior art, when the bucket is digging out highly sticky soil, a large amount of soil will stick to the inside of the bucket. As the loading operation continues, more and more soil accumulates in the bucket, which greatly increases the weight of the entire bucket, thereby increasing the fuel consumption of the loader. Usually, the soil is cleaned manually, but manual cleaning is difficult and time-consuming due to the angle limitation of the bucket. At the same time, the loader must be stopped for a period of time for cleaning, which reduces the operating efficiency of the loader.

[0004] Therefore, there is an urgent need for a loader bucket that can replace manual work to efficiently clean the soil inside the bucket. Summary of the Invention

If the specific posture changes, the directional indication will also change accordingly.

[0036] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention.

[0037] See attached Figure 1-6 , a loader bucket is shown, including a bucket 1, specifically a first clamping plate 34 and a second clamping plate 35 are welded in parallel on the top of the bucket 1, that is, the upper blade. In order to reduce the weight of the bucket 1, the first clamping plate 34 and the second clamping plate 35 are hollow structures closed on all sides. Both ends of the first clamping plate 34 and the second clamping plate 35 are provided with locking holes 32. The bucket 1 is clamped to the base frame 3 with a U-shaped cross-section through the first clamping plate 34 and the second clamping plate 35. The base frame 3 is provided with a bearing plate 4. The bearing plate 4 is close to the bucket 1. One side is provided with a first leg 5 and a second leg 6 in parallel along the length direction. The first leg 5 and the second leg 6 are respectively provided with a first card slot 7 and a second card slot 8. The first card slot 7 and the second card slot 8 can respectively accommodate the first card plate 34 and the second card plate 35. At the same time, a locking hole 32 is also opened on the first leg 5 and the second leg 6 through the first card slot 7 and the second card slot 8. A locking pin 33 is provided in the locking hole 32. The base frame 3 is detachably connected to the bucket 1 through the cooperation of the locking hole 32 and the locking pin 33.

[0038] A guide plate 9 is welded on the bearing plate 4 along the length direction, and a guide groove 10 is opened on the guide plate 9, and a plurality of first through holes 22 are opened through the guide groove 10 and at equal intervals. At the same time, a sliding plate 13 is slidably provided in the guide groove 10, and a second through hole 23 is opened on the sliding plate 13 at equal intervals with the first through hole 22. The radius of the first through hole 22 and the second through hole 23 are equal. When the sliding plate 13 is in the starting position, the second through hole 23 is exactly located in the middle of the two first through holes 22. Further, the bucket 1 is located directly below the first through hole 22 and is provided with a third through hole 24. The first through hole 22 is provided with a third through hole 24. The radii of the through hole 22 and the third through hole 24 are equal and can allow the high-pressure spray gun 19 to pass through. A mounting seat 12 is provided at one end of the carrier plate 4, and a sliding drive cylinder 11 is provided on the mounting seat 12. The sliding drive cylinder 11 is specifically a pneumatic cylinder. The telescopic end of the sliding drive cylinder 11 is connected to one end of the sliding plate 13. The sliding drive cylinder 11 can control the sliding plate 13 to move forward or backward in the guide groove 10. The distance of each movement is exactly equal to half the distance between the two first through holes 22, thereby making the second through hole 23 exactly concentric with the first through hole 22 and the third through hole 24.

[0039] A lifting mechanism is provided at the center position of the length direction of the carrying plate 4, and the lifting mechanism is provided with a frame 14. A servo motor 15 is fixed downwardly on the top of the frame 14. The output end of the servo motor 15 is connected to the connecting plate 16 through a screw thread. Guide rods 28 are provided on the left and right ends of the connecting plate 16 for sliding and stabilizing the lifting of the connecting plate 16. A crossbeam 17 is provided horizontally on the side of the connecting plate 16 close to the guide plate 9. Fixing clips 18 equal in number and position to the first through holes 22 are installed on the crossbeam 17 through bolts. A high-pressure spray gun 19 is installed in each fixing clip 18. The water inlet end of the high-pressure spray gun 19 is aligned with the water inlet end of the high-pressure spray gun 19 reserved in advance on the loader. The water tank is connected with a pipeline. When cleaning the mud inside the bucket 1, the sliding drive cylinder 11 controls the sliding plate 13 to slide forward or backward so that the first through hole 22, the second through hole 23 and the third through hole 24 are in a concentric position. Then the servo motor 15 is used to control the crossbeam 17 equipped with the high-pressure spray gun 19 to move downward and reach the inside of the bucket 1 along the first through hole 22, the second through hole 23 and the third through hole 24. Then the water tank is used to supply water to the high-pressure spray gun 19 to flush and clean the mud. In the whole process, manual cleaning is completely replaced, which greatly improves the cleaning efficiency and reduces the labor intensity.

[0040] In order to prevent hard objects from hitting the high-pressure spray gun 19 when the bucket 1 is operating, a baffle 20 is vertically provided on the side of the sliding plate 13 close to the working end of the bucket 1. At the same time, the baffle 20 is provided with an introduction seat 21 at the position of each second through hole 23. A semicircular introduction portion 25 is provided on the introduction seat 21. Through the introduction portion 25, the high-pressure spray gun 19 can be accurately inserted into the second through hole 23 when it moves downward.

[0041] In order to enable the sliding plate 13 to achieve precise matching between the first through hole 22 and the second through hole 23 when sliding, a zero point 29 is provided at the center position of the second through hole 23 of the sliding plate 13 near one end of the sliding drive cylinder 11, and correspondingly, a first adjustment scale 30 and a second adjustment scale 31 are provided on the guide plate 9 in sequence. When the cleaning operation is completed or before the sliding plate 13 slides, the zero point 29 and the second adjustment scale 31 are coincident. When the sliding plate 13 moves, the zero point 29 coincides with the first adjustment scale 30, so that it can serve as a reference for the sliding amount of the sliding plate 13.

[0042] In order to prevent the crossbeam 17 from shaking when it moves after being installed with multiple high-pressure spray guns 19, a slider 26 is provided at each end of the crossbeam 17. A guide bar 27 is fitted inside the slider 26, and one end of the guide bar 27 is fixed to the bearing plate 4.

[0043] In order to save water and reduce unnecessary waste during cleaning, a spherical nozzle is provided at the water outlet end of the high-pressure spray gun 19. The spherical nozzle has several nozzles 36 near the inside of the bucket 1, which avoids the useless work caused by spraying water outside the bucket 1.

[0044] The working principle of the present invention is as follows: when flushing and cleaning the soil in the bucket 1, the water tank on the loader is first connected through a main pipe, and then the main pipe is connected to each high-pressure spray gun 19 through multiple branch pipes. In order to control the water source, an electromagnetic valve is installed on the main pipe to realize the on and off of the water. Then, the sliding drive cylinder 11 controls the sliding plate 13 to move forward or backward along the guide groove 10 so that the first through hole 22, the second through hole 23 and the third through hole 24 are in a concentric position. At this time, the high-pressure spray gun 19 is just above the second through hole 23. Then, the servo motor 15 is used to control the crossbeam 17 to move downward so that the high-pressure spray gun 19 passes through the guide seat 21 into the bucket 1 for flushing. When the cleaning is completed, the servo motor 15 drives the crossbeam 17 to move up to the outside of the second through hole 23. Then, the sliding drive cylinder 11 controls the sliding plate 13 to slide in the opposite direction so that the sliding plate 13 covers the first through hole 22.

[0045] When the bucket 1 is used to clean dry and non-sticky materials, the entire cleaning unit 2 can be removed for ease of operation. At the same time, when the loader is turned off or idle, in order to clean the mud in the bucket 1, the high-pressure spray gun 19 can also be connected to other external water sources for cleaning.

[0046] It should be noted that in order to further reduce the weight of the cleaning unit 2 on the bucket 1, the entire chassis 3, guide plate 9, and sliding plate 13 are all made of lightweight aluminum alloy, which greatly reduces the weight of the cleaning unit 2 and avoids additional fuel consumption.

[0047] It should be noted that the high-pressure spray gun 19 is an existing item, so its specific structure and working principle are already part of the existing technology and will not be described in detail.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
