Description

Technical Field

[0001] This invention relates to the field of rake head device technology. Background Technology

[0002] During construction projects, it is usually necessary to break up the soil on the ground surface, which is typically done using a trailing suction hopper dredger. A trailing suction hopper dredger consists of a self-propelled hull and a suction device. The suction device includes a dredging head and a suction pipe, both housed within a dredging head cover. The dredging head is responsible for excavating and mixing the seabed sediment, while the suction pipe is responsible for sucking up the sediment and seawater together and transporting it through a pipeline to the self-propelled hull. The self-propelled hull is equipped with a storage bin; when the bin is full, an overflow occurs, discharging seawater and leaving behind the sediment.

[0003] The original soil-breaking function of the rake head mainly relied on the high-pressure water jet sprayed from the high-pressure water nozzle in the middle of the wear-resistant block. However, when encountering clay or other difficult-to-break and dig soil, strong mechanical soil breaking is required. Therefore, a higher-strength soil-breaking device is needed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of rakes in breaking soil, such as clay, which are difficult to break and excavate, and to provide an active rake equipped with a spiral soil breaking device.

[0005] The technical solution to achieve the above objective is: an active rake head equipped with a spiral soil-breaking device, including a rake head frame, a plurality of hydraulic rotary motors connected to the inner wall of the rake head frame, a drill bit connected to the output end of the hydraulic rotary motors, an installation mechanism provided at the bottom end of the rake head frame, an auxiliary mechanism provided inside the installation mechanism, and an adjustment mechanism installed inside the installation mechanism.

[0006] Preferably, the mounting mechanism includes a fixing plate, a mounting groove, a through hole, a mounting plate, a mounting hole, and a mounting screw. The bottom end of the rake head frame is connected to multiple fixing plates, and the bottom end of the rake head frame has multiple mounting grooves. The outer wall of the mounting groove has multiple through holes, and the inner wall of the mounting groove is inserted into and connected to the mounting plate. The outer wall of the mounting plate has multiple mounting holes, and the outer wall of the mounting hole is threadedly connected to the mounting screw. The outer wall of the mounting screw passes through the through hole, and the outer wall of the mounting screw is threadedly connected to the through hole.

[0007] Preferably, the auxiliary mechanism includes a first base plate, a cutter, a second base plate, and square grooves. The bottom end of the mounting plate is fixedly connected to the second base plate, and the bottom end of the mounting plate is slidably connected to two symmetrically distributed first base plates. The outer walls of the first base plates and the outer walls of the second base plates are both connected to the cutter, and the outer wall of the second base plate is provided with multiple square grooves.

[0008] Preferably, the adjustment mechanism includes a support block, guide rods, sliding plates, clamping plates, and limiting members. Multiple guide rods are connected to the outer walls of every two fixed plates. Two symmetrically distributed sliding plates are slidably connected to the outer walls of the guide rods. Two symmetrically distributed clamping plates are connected to the outer walls of the sliding plates. Multiple square grooves are provided on the outer walls of the support block. The square grooves on the support block are aligned with the square grooves on the second base plate.

[0009] Preferably, the second base plate is located at the center of the mounting plate.

[0010] Preferably, the lengths of the first base plate, the second base plate, and the cutter are all greater than the length of the drill bit.

[0011] Preferably, the clamping plate and the sliding plate form a U-shape, the first base plate is located between the clamping plate and the sliding plate, and the first base plate is stuck between the clamping plate and the sliding plate, and the support block is C-shaped.

[0012] Preferably, the limiting component includes a circular hole, a limiting hole, an outer tube, a sliding hole, a connecting hole, an inner rod, a slider, and a limiting screw. Circular holes are provided on the upper and lower sides of the outer wall of the slide plate, penetrating the outer wall of the slide plate. Limiting holes are provided at the bottom and top of the support block. An outer tube is connected to the inner wall of the circular hole on one side of the slide plate, and a sliding hole is provided on the outer wall of the outer tube. A slider is connected to the inner wall of the circular hole on the other side of the slide plate, and the outer wall of the slider is slidably connected to the sliding hole. An inner rod is connected to the outer wall of the slider, and the outer wall of the inner rod is slidably connected to the inner wall of the outer tube. Multiple connecting holes are provided on the outer walls of both the outer tube and the inner rod. Limiting holes are provided at the top and bottom of the support block. The diameter of the circular hole is larger than the diameter of the inner rod. A limiting screw is threadedly connected to the inner wall of the limiting hole. Both the outer tube and the inner rod penetrate the support block.

[0013] The beneficial effects of this invention are:

[0014] 1) Start the hydraulic rotary motor, which drives the drill bit to rotate and break up hard soil clods. When the rake frame moves, the auxiliary mechanism is used to cut the soil clods on the drill bit's path, thus separating the soil clods and improving the breaking effect of the drill bit.

[0015] 2) The adjustment mechanism is used to move and fix the positions of the first and second base plates, allowing the first and second base plates to move along with the cutter to adjust the position of the cutter. When cutting hard soil, the first base plates located on both sides of the second base plate will move to both ends of the mounting plate, separating the second and first base plates, and thus separating multiple cutters to cut the whole block of hard soil into multiple pieces, thereby improving the breaking effect of the drill bit. When cutting cohesive or soft soil, the first base plates located on both sides of the second base plate move towards the second base plate, so that the first and second base plates are in contact, reducing the adhesion surface area with the cohesive or soft soil and reducing the resistance experienced by the first and second base plates.

[0016] 3) Push the slide plate, using the first base plate to clamp between the clamping plate and the slide plate. The slide plate drives the first base plate to slide on the guide rod. The first base plate drives the cutter to move. The square groove is to avoid interference between the support block and the second base plate on the movement of the clamping plate. When the slide plate is pushed, it will also drive the outer tube and inner rod to move. When the connecting hole on the inner rod and the connecting hole on the outer tube are aligned with the limiting hole, the limiting screw is screwed into the limiting hole and the connecting hole to fix the outer tube and the inner rod, thereby fixing the slide plate and achieving the effect of fixing the first base plate and the second base plate, thereby achieving the effect of moving and fixing the cutter.

When cutting cohesive or soft soil, the first base plate 501 located on both sides of the second base plate 503 moves towards the second base plate 503, so that the first base plate 501 and the second base plate 503 are in contact, reducing the adhesion surface area with the cohesive or soft soil, and reducing the resistance experienced by the first base plate 501 and the second base plate 503.
