Description

Technical Field

[0001] The utility model relates to the field of backhoe dredgers, in particular to a stone breaker for a backhoe dredger. Background Art

[0002] A backhoe dredger is an engineering ship mainly used for dredging and cleaning waterways to ensure the smooth navigation of ships. The backhoe dredger is usually installed on a ship or barge. Its appearance is similar to that of a backhoe excavator used on land, but it is larger in size to meet the needs of deep-water operations. The main feature of this ship is that it has a fixed backhoe dredging machine device, which increases the stability and safety of construction operations. The boom arm is generally very large, and the bucket at the end is much larger than the bucket used on land.

[0003] During operation, the backhoe dredger uses a diesel engine to drive the control unit to excavate seabed materials through a rotating mechanical device without having to relocate the ship. The boom device is driven by a hydraulic cylinder, enabling the bucket and boom to withstand a large load. The operator sits in the cab to control the movement of the boom. Some of the largest backhoe dredgers in the world can excavate depths exceeding 30 meters. Although most models are not that large, they can still easily reach the bottom of the riverbed.

[0004] In the patent with the publication number CN206706874U, a stone breaker for a backhoe dredger is disclosed, which includes a base plate, a connecting body, a stone-breaking main body, and a reinforcing body. The connecting body is arranged on one side of the base plate to be connected with the backhoe boom. The stone-breaking main body is arranged on the other side of the base plate. The stone-breaking main body is integrally bent like a hook, and the outer end of the stone-breaking main body has a pointed hook tooth tip. The reinforcing bodies are respectively arranged on both sides of the stone-breaking body at the connection of the base plate and the stone-breaking main body to reinforce the connection between the base plate and the stone-breaking body. The stone breaker for the backhoe dredger improves the excavation ability of the backhoe dredger, and its stone-breaking ability is very obvious for some very hard isolated rock shallows.

[0005] Although the above patent realizes the effect of improving the excavation ability of the backhoe dredger and having a very obvious stone-breaking ability for some very hard isolated rock shallows, due to the integral structure of the stone-breaking main body and the base plate, when the stone-breaking main body is damaged, the entire stone breaker needs to be replaced, resulting in a relatively high use cost and inconvenience. Therefore, technological innovation is carried out on this basis. Summary of the Utility Model

A connecting pin is movably connected inside the U-shaped block, and a limiting ring is movably connected on the surface of the connecting pin. A connecting hole is formed on the surface of the connecting pin, and the stone-breaking main body is movably connected on the surface of the connecting pin.

[0008] Furthermore, the limiting component further includes a mounting plate fixed on the side surface of the base plate, and a mounting hole is formed on the surface of the mounting plate. The limiting component further includes a limiting column fixed on the side surface of the base plate.

[0009] Furthermore, a groove is formed on the surface of the stone-breaking main body, and the surface of the groove fits with the surface of the limiting column.

[0010] Furthermore, the surface of the convex column fits with the inner wall of the connecting hole, and the surface of the sliding column contacts with the inner wall of the sliding groove.

[0011] Furthermore, the reinforcing component includes a connecting sleeve fixed on the surface of the stone-breaking main body. Side teeth are arranged inside the connecting sleeve, and a first bolt and nut are arranged on the surface of the connecting sleeve.

[0012] Furthermore, the reinforcing component further includes a tooth sleeve fixed on the surface of the stone-breaking main body. The reinforcing component further includes a broken stone spike fixed on the surface of the stone-breaking main body, and a second bolt and nut is movably connected on the surface of the broken stone spike.

A connecting pin 207 is movably connected inside the U-shaped block 201, and a limiting ring 208 is movably connected on the surface of the connecting pin 207. A connecting hole 209 is opened on the surface of the connecting pin 207, and a stone breaking main body 210 is movably connected on the surface of the connecting pin 207.

[0024] As Figures 1-4 shown, the limiting component 2 further includes a mounting plate 211 fixed on the side surface of the base plate 1, and a mounting hole 212 is opened on the surface of the mounting plate 211. The limiting component 2 further includes a limiting column 213 fixed on the side surface of the base plate 1.

[0025] AsFigures 1-4 As shown, a groove 214 is formed on the surface of the stone-breaking main body 210, and the surface of the groove 214 is attached to the surface of the limit post 213.

[0026] As Figures 1-4 shown, the surface of the convex post 205 is attached to the inner wall of the connection hole 209, and the surface of the sliding post 206 contacts the inner wall of the sliding groove 203.

[0027] In implementation, when it is necessary to disassemble and replace the stone-breaking main body 210, by sliding the sliding post 206, the sliding post 206 drives the convex post 205 to slide, so that the convex post 205 is separated from the connection pin 207, and the connection pin 207 is slid, and the stone-breaking main body 210 can be separated, which is convenient for replacement when the stone-breaking main body 210 is damaged. Since the connection pin 207 and the limit ring 208 and the limit ring 208, by replacing the limit rings 208 of different lengths, it is convenient to adjust the number of stone-breaking main bodies 210 according to actual needs.

[0028] Embodiment Two:

[0029] As Figures 1-4 shown, on the basis of Embodiment One, the present utility model provides a technical solution: The reinforcement assembly 3 includes a connection sleeve 301 fixed on the surface of the stone-breaking main body 210, a side tooth 302 is arranged inside the connection sleeve 301, and a bolt and nut one 303 is arranged on the surface of the connection sleeve 301.

[0035] When the stone-breaking main body 210 needs to be disassembled and replaced in this technical solution, by sliding the sliding column 206, the sliding column 206 drives the convex column 205 to slide, so that the convex column 205 is separated from the connecting pin 207, and the connecting pin 207 is slid, and the stone-breaking main body 210 can be separated, which is convenient for replacing the stone-breaking main body 210 when it is damaged. Since the connecting pin 207 is connected to the limiting ring 208 and the limiting ring 208, by replacing the limiting rings 208 with different lengths, it is convenient to adjust the number of the stone-breaking main bodies 210 according to actual needs. By providing a gear sleeve 304 on the side surface of the reinforcement component 3, since the gear sleeve 304 is made of a high-strength wear-resistant material, it can effectively protect the stone-breaking main body 210 from wear or reduce wear during stone breaking. At the same time, a connecting sleeve 301 and side teeth 302 are provided on the side surface of the stone-breaking main body 210, which can improve the crushing effect during stone breaking and has better practicability.
