Description

Novel reamer mud pump all-in-one

The technical field is as follows:

the invention relates to a silt suction device, which comprises a motor, a dredge pump, a reamer and a gear box. The method is mainly used for dredging work of a dredger and assisting sea filling and land reclamation work.

Background art:

the cutter suction type dredging device on the existing dredger is assembled by an independent dredge pump and an independent reamer device, the reamer is driven by an independent motor, the dredge pump is placed at other positions, and a silt suction port is placed near the reamer. Such a mechanism is relatively complex, complicated in structure and large in volume. The flexibility of dredging is not facilitated.

Under normal operating condition, after the motor circular telegram, drive the pivot and rotate, the reamer is also driven simultaneously, and the reamer stirs at the bottom of a river, mixes silt and water at the bottom of a river, then carries other places with muddy water through installing the mud pump delivery pipeline near the reamer, has increased the complexity of reamer device so, need use two motors, one is used for driving the reamer and rotates, and one is used for driving the mud pump and carries mud. The problem of complicated structure and complicated control exists.

The invention content is as follows:

the invention aims to overcome the defects of the prior art and provide a novel cutter suction type motor dredge pump, which can be used by technicians for more convenient operation and control, has a simple structure, can fully suck silt at the river bottom and is used for subsequent research and analysis.

In order to achieve the above object, an embodiment of the present invention provides a cutter-suction type motor dredge pump, which is formed by combining a motor, a dredge pump impeller and a winch, wherein the motor mechanism is connected to the winch and is driven by a same rotating shaft to rotate, the winch is driven by a gear box to decelerate and rotate, so as to increase torque, and the reamer mechanism is also driven by the same rotating shaft to rotate, so that the motor drives the impeller, the reamer and the winch to rotate.

The motor rotor rotating shaft of the cutter suction type motor dredge pump is made of a hollow pipeline, an impeller is arranged in the motor rotor rotating shaft, and the circumference of the impeller is connected with the inner circle of the rotor rotating shaft.

Further the reamer is coaxially connected with the motor.

Further, the motor is coaxially connected with the winch.

The invention has the advantages that the mud dredging operation and the mud sucking operation can be simultaneously operated, the operation efficiency is improved, and the operation control is simple and the equipment structure is simple because only one motor is provided.

The working principle of the cutter-suction type motor mud pump is as follows:

the cutter suction type motor dredge pump is composed of a motor, a dredge pump, a reamer and a gear box, the dredge pump is formed by modifying and manufacturing the motor, an impeller and a rotor shaft, the impeller is installed inside the rotor shaft, the outer end of the impeller is connected with the rotor shaft, a rotor rotating shaft penetrates through the front and the back of the motor, the impeller can be driven to rotate by the rotation of the motor to suck silt, the reamer mechanism is installed at one end of the rotor shaft, and the reamer is driven to rotate by the gear box installed on the rotor shaft.

while the following detailed description illustrates embodiments of the present invention and other advantages and features of the present invention will be readily apparent to those skilled in the art from this detailed description, it should be understood that the detailed description set forth below is only a few embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any inventive step are within the scope of the present invention.

Referring to fig. 1, the cutter suction type motor dredge pump is formed by combining a motor, a winch mechanism, a gear box and a reamer mechanism, wherein the motor mechanism comprises an impeller 3, the impeller 3 is arranged inside a motor rotating shaft and connected with a motor rotor rotating shaft, and the impeller is driven to rotate when the motor rotates, so that muddy water is transported to other positions. The gear box is arranged in the winch and divides positive rotation and reverse rotation, so that the motor moves left and right, the gear 6 is a positive rotation gear, the gear 5 is a reverse rotation gear, the positive rotation gear and the reverse rotation gear are connected with the winch, and the rotation of the gear drives the winch to rotate. The reamer 7 is connected with the rotating shaft 4 through a bearing.

The structure of the invention drives the reamer 7 to rotate through the rotation of the motor rotor, fully stirs the sediment of the river bottom and water, so that the motor simultaneously drives the rotor rotating shaft 4, the rotating shaft 4 is hollow, the impeller 3 is arranged in the rotating shaft 4, the impeller 3 is driven to rotate, and the muddy water is transported to other positions through the rotating shaft pipeline, thereby realizing the dredging and sediment collection work. The gear boxes 5 and 6 can move the motor left and right through forward and reverse rotation to fully stir and mix the sediment at the river bottom.

As can be seen from the above, the invention has the advantages of small occupied space, simple structure and convenient control.

While the invention has been described in terms of what are presently considered to be the most practical and preferred embodiments, it will be apparent to those skilled in the art that many changes and modifications can be made without departing from the spirit and scope of the invention.
