Description

Technical Field

[0001] The present invention relates to the technical field of slag raking machines, and particularly to a slag raking machine with a hydraulic breaker. Background Art

[0002] A slag raking machine, also known as an excavating loader, combines a manipulator and a conveyor. The functions of slag raking and conveying and loading are integrated into one. It adopts an electric full-hydraulic control system and production device, featuring safety, environmental protection, low energy consumption, and high efficiency.

[0003] During the process of tunneling, a large amount of crushed stones will accumulate. Therefore, construction workers need to clean up the crushed stones before further tunneling. The excavating loader is used to clean the crushed stones. However, the existing excavating loaders can only clean small pieces of crushed stones. When it is necessary to clean large pieces of crushed stones, construction workers need to use a percussion drill to break the large pieces of crushed stones, or replace the bucket on the excavating loader with a breaker. However, the replacement process requires multiple construction workers to assist manually, which is troublesome to operate and the operation efficiency is extremely low. For another type of breaker fixed to the forearm with a connecting rod, although it does not require frequent disassembly and assembly of the bucket or the breaker, since the breaker is directly fixed to the forearm, the working angle of the breaker cannot be adjusted arbitrarily. Therefore, construction workers need to adjust the position of the large pieces of crushed stones before breaking, which is cumbersome to operate. Summary of the Invention

The output end of the double-headed hydraulic cylinder 16 is rotatably connected to the second connecting rod 17. The angle between the second connecting rod 17 and the switching structure 20 is adjusted by the second hydraulic cylinder 18.

[0028] In this embodiment, the switching structure 20 is divided into a mounting member and a fixing member. The mounting member and the fixing member on the switching structure 20 are rotatably connected. A second servo motor 26 is arranged at one end of the mounting member on the switching structure 20. A bevel gear 27 is installed at the output end of the second servo motor 26. Electric cylinders 29 are arranged on both sides inside the mounting member of the switching structure 20. A ring gear 28 is arranged at the bottom of the fixing member on the switching structure 20. Limit members 30 are arranged on both sides of the ring gear 28.

[0029] In this embodiment, the mounting member and the fixing member on the switching structure 20 are rotatably connected through the ring gear 28. The bevel gear 27 meshes with the ring gear 28. The output end of the second servo motor 26 passes through the mounting member and is connected to the bevel gear 27. The mounting member can rotate on the fixing member through the rotation of the output end of the second servo motor 26.

[0030] In this embodiment, the rotating member 3 is rotatably connected to the base 1. A toothed ring is arranged at the bottom of the outer surface of the rotating member 3. A gear is arranged at the output end of the first servo motor 2. The gear on the first servo motor 2 meshes with the toothed ring on the rotating member 3.

[0031] In this embodiment, a thread is arranged on the outer surface of the rotating member 3. A threaded hole is arranged at the bottom of the sliding member 6.

[0032] In this embodiment, lugs are provided on both the top and one side of the connecting seat 23. Connecting holes are provided at the middle positions of one end of the connecting seat 23 and one end of the lug. The connecting seat 23 is rotatably connected to the output ends of the switching structure 20, the third hydraulic cylinder 21, and the fourth hydraulic cylinder 22 through the connecting holes. By extending and retracting the output ends of the third hydraulic cylinder 21 and the fourth hydraulic cylinder 22, the rotation angle of the connecting seat 23 can be adjusted.

[0033] In this embodiment, a connecting block is provided on the fixing member of the switching structure 20.

[0034] Example 1, as Figures 1-4 shown, the construction worker adjusts the lifting height of the bottom plate 7 by controlling the extension and retraction degree of the output end of the first hydraulic cylinder 5. And according to the different extension and retraction degrees of the output ends of the first hydraulic cylinders 5 on both sides, the lifting degrees on both sides of the bottom plate 7 can be different. Even if the first servo motor 2, the rotating member 3, and the sliding member 6 are not provided between the base 1 and the bottom plate 7, the purpose of lifting the bottom plate 7 can still be achieved. However, the stability of the lifting of the bottom plate 7 is poor, and it will cause a reduction in the transportation volume of the conveyor belt 13. And a connecting hole is provided at the bottom of the base 1, so that the construction worker can fix the base 1 on the driving device, which is convenient for the handling of the slag scraping device.

[0035] Example 2, as Figures 5-7 shown, the construction worker drives the connecting seat 23 to flip through the switching structure 20 to achieve the purpose of adjusting the bucket 24 and the breaker 25, without the need to frequently disassemble and assemble the bucket 24 and the breaker 25. At the same time, through the cooperation between the third hydraulic cylinder 21 and the fourth hydraulic cylinder 22, the angles of the bucket 24 and the breaker 25 can be flexibly adjusted. Since the switching structure 20 is divided into a mounting member and a fixing member, the output end of the second servo motor 26 can drive the bevel gear 27 to rotate, which cooperates with the ring gear 28 to drive the mounting member to rotate on the fixing member. And the cooperation between the electric cylinder 29 and the limiting member 30 can fix the connection between the mounting member and the fixing member, avoiding the situation that the mounting member rotates when the bucket 24 and the breaker 25 are working. Among them, the breaker 25 can be replaced with other crushing equipment and drilling equipment, so that the device can also perform drilling operations on the tunnel wall surface, facilitating the subsequent blasting of the construction worker and reducing the tunnel blasting steps.

[0036] Working principle: The construction workers start the first servo motor 2 and the first hydraulic cylinder 5, so that the output end of the first servo motor 2 drives the bevel gear to rotate, thereby driving the toothed ring on the rotating member 3 to rotate, causing the rotating member 3 to rotate on the base 1, driving the sliding member 6 to lift and lower, and cooperating with the telescopic movement of the output end of the first hydraulic cylinder 5 to drive the bottom plate 7 to lift and lower on the base 1. Moreover, the construction workers can make both sides of the bottom plate 7 tilt slightly through the telescopic degree of the output ends of the first hydraulic cylinders 5 on both sides of the base 1, so as to adapt the bottom plate 7 and the conveyor belt 13 to working grounds of different heights and slag soil machines of different specifications; and during construction, by switching the structure 20, the connecting seat 23 is driven to flip, achieving the purpose of adjusting the bucket 24 and the breaker 25, without the need to frequently disassemble and assemble the bucket 24 and the breaker 25. At the same time, through the cooperation between the third hydraulic cylinder 21 and the fourth hydraulic cylinder 22, the angles of the bucket 24 and the breaker 25 can be flexibly adjusted.

[0037] For those skilled in the art, the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or scope of the present invention. Therefore, the embodiments of the present invention are exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
