The rake is inserted into the water, the rake claws are inserted into the hard soil, and then the rake is dragged to make the rake claws slide in the hard soil to break up and peel off the hard soil.

[0003] The existing patent number CN216273665U discloses a bottom mud loosening device for river silt dredging, including a long rod with a winch and a cross bar connected to the long rod. A pulley and a plurality of downwardly extending mud loosening columns are arranged on the cross bar. A folding mud loosening assembly is arranged on the mud loosening column. A plumb bob for driving the folding mud loosening assembly is arranged inside the mud loosening column. The plumb bob is connected with a longitudinal cable. The longitudinal cable extends upward and is connected with a transverse cable. The transverse cable is arranged inside the cross bar. The transverse cable is connected with a traction cable. The traction cable passes through the cross bar and is mounted on the pulley and extends outward into the winch. By controlling the winch, the shape of the mud loosening device can be quickly switched. It can not only peel off the whole piece of silt, but also loosen and dredge the soft silt, fully meeting the different states of the river bottom silt, dredging the river bottom silt more thoroughly, saving manpower and providing efficient help for the river dredging work at the same time.

[0004] In the above way, it is found in use that when the shape of the mud loosening device is switched, manual limiting and locking of the traction cable are required, resulting in waste of labor. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides a bottom mud loosening device for dredging hard soil, including a cross bar and a traction cable, and further including a locking mechanism. The locking mechanism includes a lock frame, a locking block, a resisting block, a moving block and a driving component. The lock frame is fixedly installed on the cross bar. The locking block is detachably installed on the lock frame. The moving block is slidably installed on the lock frame. The resisting block is fixedly connected with the moving block. The traction cable is located between the locking block and the resisting block. The driving component is arranged on the lock frame.

[0007] Among them, the driving component includes a lead screw, a disc, a grip and a locking member. The lead screw is rotatably installed on the lock frame. The moving block is threadedly connected to the lead screw. The disc is fixedly installed on the upper end face of the lead screw. The grip is fixedly installed on the upper end face of the disc. The locking member is arranged on the lock frame.

[0008] Among them, the locking member includes a locking hole, a locking rod and a protective component. The locking hole is located on the lock frame. The locking rod is matched with the locking hole. The protective component is arranged on the locking block.

[0009] Among them, the protective component includes a protective pad, a protection pad and a guiding element. The protective pad is detachably installed on the locking block. The protection pad is detachably installed on the resisting block. The guiding element is arranged on the lock frame.

[0010] Among them, the guiding element includes a guiding block and a guiding rod. The guiding block is fixedly connected to the resisting block. The guiding rod is slidably connected to the guiding block. The guiding rod is fixedly installed on the lock frame.

[0011] For a bottom mud loosening device for dredging hard soil of the present utility model, by driving the disc to rotate through the grip, the rotation of the disc drives the lead screw to rotate. The rotation of the lead screw drives the moving block to move in the adjustment groove. The movement of the moving block drives the resisting block to move. The movement of the resisting block contacts the traction cable. The locking block and the resisting block cooperate to resist and fix the traction cable, eliminating the need for manual limiting and locking of the traction cable, and solving the problem that in the existing device during use, when switching the form of the mud loosening device, manual limiting and locking of the traction cable is required, resulting in waste of labor.
