Description

Technical Field

[0001] The utility model relates to the technical field of riprap and silt-squeezing soft soil treatment, and specifically discloses a riprap and silt-squeezing soft soil treatment excavation device. Background Art

[0002] Stone throwing and silt squeezing is a common method for dealing with soft soil roadbed. It mainly involves throwing a certain amount of gravel from the middle of the foundation to both sides to squeeze the silt out of the project area, thereby replacing the silt and improving the bearing capacity of the foundation. The silt squeezed out of the ground is removed by excavators and dump trucks, transported to a designated dump site, and then thrown in stone chips for compaction.

[0003] The existing excavator used for stone throwing and silt squeezing soft soil treatment needs to perform stone throwing operation during use. During the stone throwing process, the direction in which the gravel falls is the same as the digging direction of the bucket, resulting in that when the gravel is thrown from a high place, the gravel will roll toward the excavator and easily hit the excavator. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, the present application aims to provide an excavation device for treating soft soil by throwing stones and squeezing silt, comprising a bucket installed on an excavator, a first baffle being provided on the inner side of the bucket, a winding mechanism symmetrically distributed on the inner side of the first baffle being fixedly installed on the inner side of the bucket, a fixed rod being rotatably connected to the inside of the bucket, a baffle plate located on the outer side of the bucket being fixedly sleeved on the outer sides of both ends of the fixed rod, and bucket teeth being fixedly installed on the outer side of one side of the baffle plate.

[0005] Preferably, the winding mechanism includes a hydraulic motor fixedly mounted on the inner side of the bucket, a winding wheel located on the outer side of the bucket is fixedly sleeved on the outer side of the output shaft of the hydraulic motor, a steel wire rope with one end sleeved on the inside of a fixed rod is wound around the inner side of the winding wheel, and a fixed sleeve is provided on the outer side of one end of the steel wire rope extending out of the fixed rod.

[0006] Preferably, a second baffle plate located above the first baffle plate is provided on the outer side of the bucket.

[0007] Preferably, a limiting plate located below the fixing rod is provided on the inner side of the bucket, and a rounded corner located outside the fixing rod is provided on the outer side of the bucket.

[0008] The beneficial effects are as follows:

[0009] 1. The stone throwing and silt squeezing soft soil treatment excavation device can drive the winding wheel to rotate and relax the wire rope through the drive of the hydraulic motor, so that the material blocking plate can rotate around the axial direction of the fixed rod, so that when the excavator is performing stone throwing operations, the falling direction of the gravel inside the bucket is opposite to the excavation direction of the bucket, thereby ensuring that when the gravel is thrown from a high place, the gravel will not roll toward the excavator and is not easy to hit the excavator.

[0010] 2. The rock dumping and silt squeezing soft soil treatment excavation device can shield and protect the hydraulic motor through the cooperation of the first baffle plate and the second baffle plate, so that the crushed stones will not collide with the hydraulic motor.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0019] See also Figure 1-4A device for treating soft soil by throwing stones and squeezing silt comprises a bucket 1 mounted on an excavator, a first baffle plate 2 is arranged on the inner side of the bucket 1, a winding mechanism 3 symmetrically distributed on the inner side of the first baffle plate 2 is fixedly mounted on the inner side of the bucket 1, a fixing rod 4 is rotatably connected to the inside of the bucket 1, and baffle plates 5 located on the outer side of the bucket 1 are fixedly sleeved on the outer sides of both ends of the fixing rod 4, the discharge port of the bucket 1 can be shielded by the baffle plate 5 to prevent gravel from falling from the discharge port, and when the baffle plate 5 is closed, the excavator can perform excavation operations on the silt through the excavation device, and a bucket tooth 6 is fixedly mounted on the outer side of one side of the baffle plate 5.

[0020] Among them, the winding mechanism 3 includes a hydraulic motor 31 fixedly installed on the inner side of the bucket 1, and a winding wheel 32 located on the outer side of the output shaft of the hydraulic motor 31 is fixedly sleeved on the outer side of the bucket 1. A wire rope 33 with one end sleeved inside the fixed rod 4 is wound around the inner side of the winding wheel 32. The wire rope 33 can be tensioned and relaxed through the winding wheel 32 by the drive of the hydraulic motor 31, thereby realizing the automatic opening and closing of the material baffle plate 5. A fixing sleeve 34 is provided on the outer side of one end of the wire rope 33 extending from the outside of the fixed rod 4, and the wire rope 33 can be limited by the fixing sleeve 34, so that the material baffle plate 5 can be tightly closed between the wire rope 33 and the bucket 1 when the wire rope 33 is tensioned, and the wire rope 33 is not easily damaged when colliding with gravel, ensuring that the silt will not leak from the inside to the outside of the bucket 1 when the excavator is excavating the silt.

[0021] Among them, a second baffle plate 7 is arranged on the outer side of the bucket 1 and is located above the first baffle plate 2. The first baffle plate 2 and the second baffle plate 7 can shield and protect the second baffle plate 7 to prevent the gravel from colliding with the hydraulic motor 31 during the gravel excavation process of the excavator.

[0022] Among them, a limit plate 8 located below the fixed rod 4 is provided on the inner side of the bucket 1, and the limit plate 8 can be used to limit and support the bucket 1, so that the part where the bucket 1 and the fixed rod 4 are connected is not easy to deform, thereby ensuring that the fixed rod 4 can stably rotate inside the bucket 1, and a rounded corner is provided on the outer side of the bucket 1 on the outer side of the fixed rod 4, so that the material baffle plate 5 will not interfere with the bucket 1 during the rotation around the axial direction of the fixed rod 4.

[0023] When the excavator is excavating gravel, the hydraulic motor 31 drives the winding wheel 32 to rotate while the wire rope 33 is tensioned. During this process, the material baffle plate 5 can rotate and close around the axial direction of the fixed rod 4. At this time, the excavator excavates the gravel through the bucket 1. After the gravel excavation is completed, the bucket 1 is moved to a suitable position height, and the reverse drive of the hydraulic motor 31 drives the winding wheel 32 to rotate in the reverse direction while the wire rope 33 is relaxed. At this time, under the action of the gravity of the gravel and the material baffle plate 5, the material baffle plate 5 is driven to rotate in the reverse direction around the axial direction of the fixed rod 4, and the discharge port of the bucket 1 is opened. The gravel is thrown from the discharge port under the action of its own gravity.
