Problems solved by technology

[0008]The purpose of the present invention is to solve the problems existing in the prior art due to the unevenness of the rock bottom at the bottom of the channel, and the poor adaptability of the cutting depth of the hob used in the patent, resulting in The wear rate of some hobs with a large cutting depth increases, and the hobs with a small cutting depth have poor rock-soil damage performance, which is not conducive to improving the dredging effect of the channel; it is inconvenient to disassemble when replacing the damaged hob, and the loading and unloading efficiency is low; lack The pre-processing device for rock and soil crushing increases the difficulty of crushing the hob, and proposes a rapid and automatic excavating rake head for seabed mud

Embodiment 1

[0046] refer to Figure 1-8 , a rake head for rapid and automatic excavation of seabed mud, comprising a rake head cover 10, rake teeth 110 installed at the front end of the rake head cover 10, an underwater deceleration motor 20 installed on the side wall of the rake head cover 10, and an underwater deceleration motor The transmission shaft 210 at the output end of the 20 and located in the cavity of the rake head cover 10 also includes,

[0047] The first transmission bevel gear set 30 is equidistantly set on the outer wall of the transmission shaft 210, and is used to convert the axial rotation of the transmission shaft 210 into a direction-adjustable radial rotation;

[0048] The transmission rod 40 is installed on the transmission end of the first transmission bevel gear set 30;

[0049] The buffer adjustment mechanism 80 is installed in the middle section of the transmission rod 40, and is used for adjusting the angle between the transmission rod 40 and the transmission...

Embodiment 2

[0062] refer to Figure 5-10 , a rapid and automatic excavation drag head for seabed mud, which is basically the same as that of Embodiment 1. Furthermore, the pre-crushing mechanism 70 is rotatably connected to the third U-shaped frame 710 on the outer wall of the drive shaft 210, and is rotatably connected to the third U-shaped frame. 710 is the third driven bevel gear 720 that is horizontally sectioned and only meshes with one of the first driving bevel gears 310, and the breaking rod 730 that is fixedly installed on the driving end of the third driven bevel gear 720 is installed on the breaking rod 730 away from the third driven bevel gear. The crushing head 740 at one end of the bevel gear 720, the second collar 750 set in the middle of the crushing rod 730, the second connecting piece 760 movably connected to the outer wall of the second collar 750, and the second connecting piece 760 movably connected to the inner wall of the rake head cover 10 and the second link. The ...

Abstract

The invention discloses a rapid and automatic excavating drag head for seabed mud, and belongs to the technical field of equipment for dredging engineering. A rapid and automatic digging rake head for seabed mud comprises a rake head cover, rake teeth installed at the front end of the rake head cover, an underwater gear motor installed on the side wall of the rake head cover and a transmission shaft installed at the output end of the underwater gear motor and located in an inner cavity of the rake head cover, and further comprises first transmission bevel gear sets arranged on the outer wall of the transmission shaft in a sleeving mode at equal intervals, and second transmission bevel gear sets arranged on the outer wall of the transmission shaft, the rotating shaft is used for converting axial rotation of the transmission shaft into radial rotation adjustable in direction; the transmission rod is mounted at the transmission end of the first transmission bevel gear set; the buffer adjusting mechanism is mounted at the middle section of the transmission rod and used for adjusting the included angle between the transmission rod and the transmission shaft; according to the pre-crushing function of the channel rock substrate, the crushing function of the rock substrate in different concave-convex states is achieved, and the problems that hob damage is aggravated due to the too large hob crushing depth and the drag suction efficiency is low due to the poor crushing effect caused by the too small crushing depth are solved.

Description

technical field [0001] The invention relates to the technical field of dredging engineering equipment, in particular to a rapid and automatic dredging head for seabed mud. Background technique [0002] With the rapid development of my country's shipping industry and the vigorous development of infrastructure projects such as ports and waterways, the domestic demand for dredging ships is increasing. Trailing suction dredger is the most commonly used dredging ship in dredging projects. It has strong wind and wave resistance, little interference to shipping, large dredging depth, and unlimited transportation distance. It is suitable for land reclamation and large ports for deep water and long-distance operations. Waterway construction and maintenance projects. At present, the working mode of the trailing suction dredger is to dredge while sailing, and a drag head is respectively installed on both sides of the ship. When the dredger is sailing, it drives the rake head to move ...
