Description

Technical Field

[0001] This utility model belongs to the field of caisson construction technology, specifically, it relates to a hydraulic mechanized soil breaking device for caisson construction. Background Technology

[0002] In the field of caisson construction, the excavation operation is a crucial step in the entire construction process, and its efficiency and quality directly affect the progress and final quality of the caisson construction. With the continuous advancement of construction technology, hydraulic mechanized excavation devices, with their advantages of high efficiency and environmental friendliness, are gradually being widely used in caisson construction.

[0003] However, in the actual hydraulic mechanized excavation operation of caisson construction, the bucket equipped with the existing hydraulic mechanized excavation device is the key component that directly contacts the soil and performs the excavation operation. After long-term continuous operation, a large amount of soil will inevitably adhere to its inner wall. This soil will not only affect the volume of the bucket due to gradual accumulation, reducing the efficiency of each excavation operation, but also increase the overall weight of the bucket, putting a greater load on the excavator's arm and affecting the service life and operational stability of the excavator.

[0004] Currently, cleaning the soil from the inner wall of the excavator bucket is extremely inconvenient. Since most existing excavator buckets adopt an integrated structure, the operating space for personnel is extremely limited during cleaning. The narrow space makes it difficult to fully utilize cleaning tools, and it is even more difficult to completely remove some firmly attached soil. This not only makes the cleaning work time-consuming and laborious, greatly reducing the cleaning efficiency, but also may cause the soil attached to the inner wall of the excavator bucket to fall off during subsequent excavation operations due to incomplete cleaning, affecting the uniformity and quality of excavation, and thus adversely affecting the overall progress of the caisson construction. To address this, we propose a hydraulically mechanized excavation device for caisson construction. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A hydraulically mechanized excavation device for caisson construction includes a boom and a bucket. The bucket is installed at one end of the boom. A groove is formed on the outer wall of the bucket, and a bucket plate is placed in the groove. The bottom end of the bucket plate is hinged to the inner wall of the groove. A slot is formed on the top of the outer wall of the bucket and the inner wall of the groove. A locking block is installed on the top of the bucket plate and is locked in the slot. A fixing component for fixing the bucket plate is provided in the slot.

[0007] In a preferred embodiment of this utility model, a connecting shaft is installed on the inner wall of the trough near the bottom. The bottom end of the bucket plate is rotatably sleeved on the outer wall of the connecting shaft through a bearing. By setting the connecting shaft, the bucket plate can be fixedly rotated in the trough.

[0008] In a preferred embodiment of this utility model, the fixing component includes a clamping plate and a fastening bolt. A shrinkage groove is provided at the top of the inner wall of the clamping slot, and the clamping plate is clamped in the shrinkage groove. The clamping plate is also clamped on the outside of the clamping block. A spring is installed between the top of the clamping plate and the top of the inner wall of the shrinkage groove. The fastening bolt is threadedly connected to a threaded hole provided on the clamping plate. A positioning groove is provided on the outside of the clamping block, and the fastening bolt is inserted into the positioning groove. By setting the clamping plate, the clamping plate can be clamped on the outside of the clamping block, thereby fixing the clamping block in the clamping slot.

[0009] In a preferred embodiment of this utility model, a limiting rod is installed at the top of the inner wall of the shrinkage groove, a rod groove is opened at the top of the clamping plate, the limiting rod is inserted into the rod groove, and the spring surrounds the outer wall of the limiting rod. By setting the limiting rod, the spring can be limited, ensuring the stability of the spring during compression.

[0010] In a preferred embodiment of this utility model, a slot is provided at the bottom outer side of the card plate, and a groove is provided between the outer wall of the bucket and the top of the inner wall of the slot. By providing the slot, it is convenient for personnel to pull the card plate through the slot, thereby facilitating personnel operation.

[0011] In a preferred embodiment of this utility model, the outer wall of the bucket plate is equipped with multiple reinforcing ribs. By setting the reinforcing ribs, the strength of the bucket plate can be increased.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model features a split bucket plate on the bucket.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown, a hydraulic mechanized soil-breaking device for caisson construction includes a boom 1 and a bucket 2. The bucket 2 is installed at one end of the boom 1. A groove 6 is opened on the outer wall of the bucket 2. A bucket plate 3 is installed in the groove 6. The bottom end of the bucket plate 3 is hinged to the inner wall of the groove 6. A slot 7 is opened on the top of the outer wall of the bucket 2 and the inner wall of the groove 6. A locking block 8 is installed on the top of the bucket plate 3. The locking block 8 is locked in the slot 7. A fixing component for fixing the bucket plate 3 is provided in the slot 7.

[0024] Furthermore, a connecting shaft 5 is installed on the inner wall of the trough 6 near the bottom, and the bottom end of the bucket plate 3 is rotatably sleeved on the outer wall of the connecting shaft 5 through a bearing.

[0025] By setting the connecting shaft 5, the bucket plate 3 can be fixedly rotated in the plate groove 6.

[0026] Furthermore, the fixing component includes a clamping plate 9 and a fastening bolt 13. A shrinkage groove 10 is provided at the top of the inner wall of the clamping groove 7. The clamping plate 9 is clamped in the shrinkage groove 10 and clamped on the outside of the clamping block 8. A spring 12 is installed between the top of the clamping plate 9 and the top of the inner wall of the shrinkage groove 10. The fastening bolt 13 is threadedly connected to the threaded hole on the clamping plate 9. A positioning groove 14 is provided on the outside of the clamping block 8. The fastening bolt 13 is inserted into the positioning groove 14.

[0027] The card plate 9 is designed to be snapped onto the outside of the card block 8, thereby fixing the card block 8 in the card slot 7.

[0028] Furthermore, a limiting rod 11 is installed at the top of the inner wall of the shrinkage groove 10, and a rod groove 17 is opened at the top of the clamping plate 9. The limiting rod 11 is inserted into the rod groove 17, and the spring 12 surrounds the outer wall of the limiting rod 11.

[0029] The limiting rod 11 can limit the spring 12 and ensure its stability during compression.

[0030] Furthermore, a slot 16 is provided at the bottom outer side of the card plate 9, and a groove 15 is provided between the outer wall of the bucket 2 and the top of the inner wall of the slot 7.

[0031] The notch 16 allows personnel to pull the card plate 9, making operation easier.

[0032] Furthermore, multiple reinforcing ribs 4 are installed on the outer wall of the bucket plate 3.

[0033] Among them, by setting the reinforcing rib 4, the strength of the bucket plate 3 can be increased.

[0034] The implementation principle of a hydraulic mechanized soil-breaking device for caisson construction is as follows: During use, the excavator's arm 1 and bucket 2 work together to break up the ground. After prolonged use, a large amount of soil will adhere to the inner wall of the bucket 2, requiring timely cleaning. To do this, first loosen the fastening bolt 13, disengaging it from the positioning groove 14 and the clamping plate 9. Then, pull the clamping plate 9 upwards through the slot 16, compressing the spring 12 and causing the clamping plate 9 to move towards the contraction groove 10. The clamping plate 9 is no longer engaged with the outside of the clamping block 8, so that the clamping plate 9 no longer limits the clamping block 8. At this time, the bucket plate 3 can be rotated downward to unfold downward and separate from the bucket 2. Through the above structure, a split bucket plate 3 is set on the bucket 2. When it is necessary to clean the bucket 2, the bucket plate 3 can be unfolded from the bucket 2, which greatly increases the operating space for personnel when cleaning the bucket 2 and the bucket plate 3, reduces the difficulty of cleaning, and improves the cleaning efficiency, avoiding affecting the progress of excavation. The structure is simple and highly practical.
