The upper jaw 3.1 and the lower jaw 3.2 of the grab bucket are provided with rotation limiting positions, which are not specifically described in the prior art, and the purpose of the rotation limiting positions is to limit the rotation angle of the upper jaw 3.1, and specifically, the rotation limiting positions can be limited by limiting angle steel as shown in fig. 1.
The initial state of the equipment is that the grab bucket 3 is opened and stays at the near top end of the shell 1.
The single-channel grid bars 11 are arranged in the ditch 5 and close to the right side of the shell 1, when water flows through the grid bars 11, various floating objects and suspended matters in water flow to the grids along with the water flow, partial small-sized garbage passes through the grid bars 11 and enters the flow channel, most of the garbage is blocked outside the grid bars 11, and the grab bucket 3 is placed down every 10min for cleaning.
When the equipment receives a cleaning signal, the motor 8.1 starts to run anticlockwise, at the moment, the hook 7 is hooked in the second hooking nest 3.1.1.2 of the second hooking part 3.1.1 of the upper jaw 3.2 of the grab bucket, along with the slow descending of the polyester belt 6, the sliding block 3.2.2 of the lower jaw 3.1 of the grab bucket rotates anticlockwise around the convex shaft 4.1 in the sliding groove at the top end close to the guide rail 4, the lower jaw 3.1 of the grab bucket is slowly lowered to be in a vertical state, when the lower jaw 3.1 of the open-close grab bucket rotates to be vertical, the concave groove 3.2.2.1 of the sliding block falls off from the convex shaft 4.1, and the open-close grab bucket 3 slowly and stably descends along the guide rails 4 at two sides.
When the opened and closed grab bucket 3 falls to the bottom end of the lower grid 11, the lower jaw 3.1 of the grab bucket 3 cannot descend, however, the terylene tape 6 continues to descend due to the anticlockwise rotation of the motor 8.1, the upper jaw 3.2 of the grab bucket is closed anticlockwise along the hinged part 12 of the upper jaw 3.2 and the lower jaw 3.1 under the action of gravity, and floaters and suspended matters at the collecting tank 13 are collected in the grab bucket 3.
After the upper jaw 3.2 of the grab bucket is closed, the hook 7 continuously descends along with the descending of the terylene tape 6, can be separated from the second hook nest 3.1.1.2 of the second hook part 3.1.1, and swings back to a vertical state under the action of gravity.
Because the upper end of the accommodating cavity 7.2 of the hook 7 is hung on the second hooking part 3.1.1, the terylene tape 6 is in a tail end unstressed state, the terylene tape 6 is not in a tightened state any more, the rocker arm 9.1 rotates clockwise and falls due to the reuse of gravity to touch the travel switch 9.2, and the motor 8.1 starts to select clockwise.
Because the hook 7 swings back to a vertical state, the hook is just hooked in the first hook nest 3.2.1.2 of the first hook part 3.2.1 when rising, and the grab bucket lower jaw 3.1 is driven to rise along the guide rails 4 on the two sides in the clockwise rotation process of the motor 8.1.
When the concave slot 3.2.2.1 of the sliding block 3.2.2 of the grab bucket lower jaw 3.1 is embedded into the convex shaft 4.1 near the top end of the guide rail 4, the grab bucket lower jaw 3.1 rotates clockwise around the convex shaft 4.1 along with the continuous rising of the terylene tape 6. When rotated to 65 deg., the hook 7 slides from the first socket 3.2.1.2 of the grapple lower jaw 3.1 into the second socket 3.1.1.2 of the upper jaw 3.2.
After the hook 7 is hooked in the second hooking socket 3.1.1.2 of the upper jaw 3.2 of the grab bucket, the upper jaw 3.2 of the grab bucket continues to rotate clockwise and slowly opens, and the intercepted materials slide into the blanking port 7 under the action of gravity.
The grab upper jaw 3.2 continues to rotate clockwise, and after touching the photoelectric sensing switch 12, the motor 6 stops and the next cycle starts.
The second signal sensing means 9 is not limited to the form described in embodiment 1, and may be any sensor capable of detecting the tightness of the polyester tape 6.
The described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
