When people use the grab bucket for a long time, it is easy to corrode and rust, resulting in a reduced use intensity of the grab bucket, the appearance of rust through holes, affecting its service life, and being inconvenient for people to use.

[0004] However, during the working process of the riprap layer cleaning grab bucket, when the grab bucket grabs materials, the materials may be too large and hard to jam the equipment, resulting in the leakage of materials. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a riprap layer cleaning grab bucket which can prevent the materials from jamming the equipment during the cleaning process of the riprap layer and can make the equipment better insert into the material pile for grabbing by setting a grabbing mechanism and a driving mechanism.

[0006] A riprap layer cleaning grab bucket of the utility model includes a grab bucket mechanism; it also includes a driving mechanism, a connecting mechanism, and a fixing mechanism. The driving mechanism is installed at the upper end of the grab bucket mechanism, the connecting mechanism is installed at the upper end of the driving mechanism, and the fixing mechanism is installed at the upper end of the connecting mechanism;

[0007] The grab bucket mechanism is used for grabbing, the driving mechanism is used for driving, the connecting mechanism is used for connecting, and the fixing mechanism is used for fixing; the equipment is hooked through the connecting mechanism, fixed through the fixing mechanism, the grab bucket mechanism is driven by opening the driving mechanism, and the materials are grabbed through the grab bucket mechanism, so that during the cleaning process of the riprap layer, the materials can be prevented from jamming the equipment, and the equipment can better insert into the material pile for grabbing.

[0008] Preferably, the grab bucket mechanism includes a main shaft, grab bucket one, grab bucket two, and multiple groups of teeth. Grab bucket one and grab bucket two are rotatably installed on the main shaft, and multiple groups of teeth are installed on both grab bucket one and grab bucket two; the materials are grabbed by the opening and closing of grab bucket one and grab bucket two, and the materials are inserted and diverted by the teeth to prevent the materials from jamming.

[0009] Preferably, the driving mechanism includes a first vertical frame, a lead screw, a motor, a threaded block, and two sets of connecting rods. The first vertical frame is installed at the upper end of the main shaft. The lead screw is rotatably installed on the first vertical frame, and the input end of the lead screw extends to the upper side of the first vertical frame. The motor is installed at the upper end of the first vertical frame, and the output end of the motor is connected to the input end of the lead screw. The threaded block is rotatably connected to the first grab and the second grab respectively through two sets of connecting rods, and the threaded block is in threaded cooperation with the lead screw. By turning on the motor to drive the lead screw to rotate, while the lead screw rotates, it is in threaded cooperation with the threaded block to make the threaded block move. While the threaded block moves, it pushes and pulls the first grab and the second grab through the connecting rods to make the first grab and the second grab open and close.

[0010] Preferably, the connecting mechanism includes a second vertical frame and a hook ring. The second vertical frame is installed at the upper end of the first vertical frame, and the hook ring is installed on the second vertical frame. The equipment is lifted by hooking the hook ring.
