Abstract
The utility model belongs to the field of dredging engineering equipment, and particularly relates to a dredger reamer for soft strata. The dredger reamer comprises a reamer base, reamer teeth and steel pins, wherein a connecting hole A is formed in the head of the reamer base; a reamer base sleeve matched with the head of the reamer base is arranged at the rear part of the reamer teeth; a connecting hole B is formed in the reamer base sleeve; reinforcing ribs are arranged on the reamer teeth; and one side of the steel pin is tooth-shaped and is matched with the connecting hole A and the connecting hole B. The dredger reamer is characterized by further comprising plastic pins; the upper end of the connecting hole A is smaller than the lower end of the connecting hole A; the plastic pins are matched with the lower end of the connecting hole A; the connecting hole B is formed in the front and back surfaces of the reamer teeth; and the reinforcing ribs are arranged at two sides of the reamer teeth and are vertical to the side. During construction, the pins are difficult to fall off; the connecting hole B and the reinforcing ribs are improved to be positioned at the different sides from the same side, so that the energy transmission efficiency is high, the stress is uniform, and the dredger reamer is difficult to break; the head of the reamer teeth is widened; and the dredging efficiency of the dredger reamer in the soft strata is improved.
Description
Technical field
The utility model belongs to the dredging works apparatus field, relates in particular to a kind of soft stratum Cutters for Dredgers.
Background technology
Port construction, water conservancy desilting, waterway dredging and the environmental protection of dredge boat in dredging works removed contamination etc. and to be played the part of extremely important role in the link, cutter suction dredger is when the mud of the soft soil layer of cleaning, because the structure of cutter seats and reamer tooth combination connecting mode and reamer tooth reinforcing rib makes reamer fall pin, fracture easily, article one, dredge boat will be installed tens cover reamers, in case falling pin will make outside cutter seats is exposed to, continue construction and then can cause the cutter seats wearing and tearing, cutter seats wearing and tearing back reparation difficulty is big, and it is long to reinstall reamer tooth elapsed time; Existing wide tooth reamer is when cleaning mud in addition, and efficient is low, has restricted giving full play to of cutter suction dredger construction production capacity to a certain extent, has influenced programming.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of soft stratum Cutters for Dredgers, comprise cutter seats, the reamer tooth, steel pin, described cutter seats head is provided with connecting hole A, described reamer tooth afterbody is provided with the reamer cover for seat that matches with the cutter seats head, described cutter seats puts and is provided with connecting hole B, described reamer tooth is provided with reinforcing rib, described steel pin one side is dentation, it cooperates with connecting hole A and connecting hole B, it is characterized in that: also comprise the glue pin, the upper end of described connecting hole A is less than the lower end, described glue pin matches with the lower end of connecting hole A, and described connecting hole B just is being arranged on the reamer tooth, reverse side, described reinforcing rib are arranged on reamer tooth two sides and and lateral vertical.
The length of described reinforcing rib is 1/2nd of reamer tine length.
The width of described reamer tooth head is consistent with the width of reamer cover for seat.
Described reamer tooth, reamer cover for seat, connecting hole B and reinforcing rib are formed in one.
The beneficial effects of the utility model are: cutter seats is connected with the glue pin by steel pin with the reamer tooth, make the matching relationship of the two more firm, make dredge boat when construction, be difficult for falling pin, effectively protected cutter seats not frayed, saved the time of after repairing cutter seats and falling pin the reamer tooth being installed; Connecting hole B is arranged on reamer tooth positive and negative, reinforcing rib be arranged on reamer tooth two sides and and lateral vertical, make connecting hole B and reinforcing rib be improved to and be in heteropleural by being in homonymy, make the utility model energy transmissibility height, stressed evenly, easy fracture not; The width of reamer tooth head is consistent with the width of reamer cover for seat, and reamer tooth head is widened, and has improved the digging efficiency on soft stratum, makes cutter suction dredger construction production capacity obtain giving full play to.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1-cutter seats, 2-reamer tooth, 3-steel pin, 4-connecting hole A, 5-reamer cover for seat, 6-connecting hole B, 7-reinforcing rib, 8-glue pin.
The cutter seats head is provided with connecting hole A, the upper end of connecting hole A is less than the lower end, reamer tooth afterbody is provided with the reamer cover for seat that matches with the cutter seats head, the width of reamer tooth head is consistent with the width of reamer cover for seat, cutter seats puts and is provided with connecting hole B, connecting hole B just is being arranged on the reamer tooth, reverse side, the reamer tooth is provided with reinforcing rib, reinforcing rib is arranged on reamer tooth two sides also and lateral vertical, the length of reinforcing rib is 1/2nd of reamer tine length, the reamer tooth, the reamer cover for seat, connecting hole B and reinforcing rib are formed in one, cutter seats and reamer tooth are that steel pin and the glue pin of dentation is connected with a side, steel pin is positioned at connecting hole A upper end and connecting hole B, and the glue pin is positioned at connecting hole B lower end and connecting hole B.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and design thereof, all should be encompassed within the protection domain of the present utility model.
