Description

Technical Field

[0001] The utility model relates to the technical field of grab buckets, in particular to a hydraulic multi - flap garbage grab bucket. Background Art

[0002] In sewage renovation, grab buckets are often used. A grab bucket is a special tool for a crane to grab dry bulk goods. It consists of two or more openable and closable bucket - shaped jaw plates that form a material - containing space together. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the material - containing space. When unloading, the jaw plates are opened in a suspended state on the material pile, and the material falls on the material pile. The opening and closing of the jaw plates are generally controlled by the wire rope of the crane hoisting mechanism.

[0003] When the grab bucket grabs the garbage in the drainage ditch (garbage in sewage), the sewage in the garbage is removed with the garbage, resulting in a lot of sewage at the place where the garbage is stacked (when the grab bucket is fully closed), causing environmental pollution. At the same time, the grab bucket tip is worn and damaged after long - term use and needs to be replaced.

[0004] Therefore, a hydraulic multi - flap garbage grab bucket is proposed to upgrade and transform on the basis of the device to solve these deficiencies. Content of the Utility Model

[0026] Such as Figures 1 to 5As shown in the figure, a hydraulic multi-lobe garbage grab includes a mounting base 13, characterized in that: a connecting plate 12 is fixedly installed at the lower end of the mounting base 13, a hydraulic cylinder 11 is fixedly installed at the lower end of the connecting plate 12, an output shaft of the hydraulic cylinder 11 is fixedly installed with a fixing plate 10, the outer end of the fixing plate 10 is rotatably connected with a grab bucket lobe 1, a sliding block 22 is slidably connected to the inner wall of the grab bucket lobe 1, one end of the sliding block 22 is fixedly connected with a grab bucket tip 2, a bolt 21 is threadedly connected to the inner wall of the grab bucket lobe 1, and one end of the bolt 21 is threadedly connected to the inner wall of the sliding block 22. The outer end of the grab bucket lobe 1 is rotatably connected with a rotating rod 14, one end of the rotating rod 14 is rotatably connected with the outer end of the connecting plate 12, a water leakage hole 16 is opened at the outer end of the grab bucket lobe 1, a hole plate 15 is slidably connected to the outer end of the grab bucket lobe 1, and an adjusting mechanism 3 is arranged inside the grab bucket lobe 1; specifically, by starting the cooperation of the hydraulic cylinder 11 and the rotating rod 14, the grab bucket lobe 1 is closed or opened, facilitating the grasping of garbage. Through the water leakage hole 16, the sewage in the garbage can be simply separated. When the bolt 21 is disassembled by a tool, the sliding block 22 can be separated from the inside of the grab bucket lobe 1, and the grab bucket tip 2 can be disassembled and replaced.

[0027] As Figure 1 , Figure 2 and Figure 5 shown, a sliding rod 19 is slidably connected to the inner wall of the grab bucket lobe 1, one end of the sliding rod 19 is fixedly installed with a push block 23, the outer end of the push block 23 abuts against the upper end of the sliding block 22, and a spring 20 is fixedly installed at the outer end of the push block 23, and one end of the spring 20 is fixedly installed with the inner wall of the grab bucket lobe 1; specifically, through the action of the spring 20, after the sliding block 22 is separated from the bolt 21, it is extruded outwards by the push block 23, facilitating the disassembly and replacement of the grab bucket tip 2.

[0028] As Figure 2 and Figure 5 shown, a stop block 18 is fixedly installed at the upper end of the sliding rod 19; specifically, to prevent the sliding rod 19 from detaching from the grab bucket lobe 1.

[0029] As Figure 2 , Figure 3 and Figure 4As shown in the figure, the adjusting mechanism 3 includes a rotating concave block 31. The inner wall of the grab bucket flap 1 is rotatably connected to the rotating concave block 31. One end of the rotating concave block 31 is fixedly installed with a first gear 33. The outer end of the first gear 33 is meshed and connected with a second gear 34. The outer end of the second gear 34 is fixedly installed with a threaded rod 38. The outer end of the threaded rod 38 is threadedly connected to a threaded plate 37. The outer end of the threaded plate 37 is fixedly connected to a connecting block 36. One end of the connecting block 36 is fixedly installed with the outer end of the hole plate 15. Specifically, by inserting a tool into the inside of the rotating concave block 31 and rotating it, the first gear 33 drives the threaded rod 38 at the outer end of the second gear 34 to rotate, so that the threaded plate 37 drives the hole plate 15 to move, causing the holes on the surface of the hole plate 15 to be misaligned with the water leakage holes 16 on the surface of the grab bucket tip 1, and adjusting the size of the water leakage holes 16.

[0030] As Figure 3 and Figure 4 shown in the figure, a limiting rod 35 is slidably connected to the inner wall of the threaded plate 37. Both ends of the limiting rod 35 are fixedly installed on the inner wall of the grab bucket flap 1. A sliding groove for the outer end of the connecting block 36 to slidably connect is formed on the surface of the grab bucket flap 1. Specifically, it is convenient for the threaded plate 37 to move stably, and improves the stability of the threaded plate 37 during movement.

[0031] In summary: When using the grab bucket to handle garbage, when there is water in the garbage or it is in a water channel, by inserting a tool into the inside of the rotating concave block 31 and rotating it, the first gear 33 drives the threaded rod 38 at the outer end of the second gear 34 to rotate, so that the threaded plate 37 drives the hole plate 15 to move, causing the holes on the surface of the hole plate 15 to be aligned with the water leakage holes 16 on the surface of the grab bucket tip 1. When the grab bucket grabs the garbage, the sewage can flow out from the water leakage holes 16, which is convenient for simply separating the garbage from the sewage;

[0032] When there is basically no water in the garbage and the volume of the garbage is small (such as the size of glass beads, etc.), it can flow out from the water leakage holes 16. By rotating the rotating concave block 31, the holes on the surface of the hole plate 15 are misaligned with the water leakage holes 16 on the surface of the grab bucket tip 1, and the size of the water leakage holes 16 is adjusted, which is convenient for handling this type of garbage;

[0033] When the grab bucket tip 2 needs to be replaced after long-term use, when the bolt 21 is disassembled by a tool, due to the acting force generated by the compressed spring 20, the push block 23 extrudes the sliding block 22 outwards, which is convenient for disassembling and replacing the grab bucket tip 2.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
