Description

Technical Field

[0001] This utility model relates to the field of dredging engineering technology, and in particular to a rake head for compacted soil. Background Technology

[0002] In dredging projects, rakes are usually used to clean the soil and achieve the purpose of unblocking. However, the soil is often highly viscous and dense. If traditional rakes are used, they are prone to forming hardening and blockage at the grid, requiring frequent shutdowns for cleaning. Each cleaning takes about 2 hours, which greatly reduces the efficiency of the work. Therefore, it is necessary to optimize and improve the rake. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rake head for compacted soil that is less prone to clogging.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a rake head for compacting soil, comprising a fixed body, a movable cover, and a flushing pipe. The fixed body and the movable cover are rotatably connected. A hydraulic cylinder is rotatably mounted on the top of the fixed body, and the output end of the hydraulic cylinder is rotatably connected to the movable cover. Multiple reinforcing grids are fixedly mounted on the lower part of one side of the fixed body, and multiple comb-tooth grids are fixedly mounted on the lower part of the movable cover. The movable cover and the flushing pipe are fixedly connected. Multiple rake teeth and nozzles are fixedly mounted on one side of the flushing pipe, and adjacent nozzles are staggered.

[0006] Preferably, the angles between the staggered nozzles and rake teeth are 40° and 5°, respectively.

[0007] Preferably, the comb-shaped grid extends through the gaps between the rake teeth.

[0008] The present invention provides a rake head for compacted soil, which has the following advantages: By optimizing the nozzle, ribbed grid, and comb-tooth grid, the fixed body is equipped with ribbed grid, the movable cover is equipped with comb-tooth grid, and the nozzles are arranged in a staggered manner at different angles to expand the spray range and achieve scouring of the rake teeth. By optimizing the three parts of the rake head, mud can be effectively prevented from clogging the rake head, thereby reducing downtime, saving cleaning time, and generating greater economic benefits.

[0009] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1-5 A rake head for compacting soil includes a fixed body 1, a movable cover 2, and a flushing pipe 3. The fixed body 1 and the movable cover 2 are rotatably connected. A hydraulic cylinder 4 is rotatably mounted on the top of the fixed body 1, which can drive the movable cover 2 to rotate. The output end of the hydraulic cylinder 4 is rotatably connected to the movable cover 2. Multiple stiffening grids 1.1 are fixedly installed on the lower part of one side of the fixed body 1. Multiple comb-tooth grids 2.1 are fixedly installed on the lower part of the movable cover 2. The movable cover 2 and the flushing pipe 3 are fixedly connected. Multiple rake teeth 3.2 and nozzles 3.1 are fixedly installed on one side of the flushing pipe 3. The adjacent nozzles 3.1 are staggered to expand the spray range of the nozzles 3.1. The nozzles 3.1 flush the rake teeth 3.2, thereby effectively preventing mud from clogging the rake head.

[0019] The angles between the staggered nozzles 3.1 and the rake teeth 3.2 are 40° and 5° respectively, which maximizes the scouring range of the nozzles 3.1 on the rake teeth 3.2.

[0020] The comb-tooth grid 2.1 penetrates the gap between the rake teeth 3.2.
