As shown in fig. 1 and 5, a telescopic device 2 is arranged between the digging arm 7 and the supporting plate 6, the telescopic device 2 includes more than one spring 11 arranged between the supporting plate 6 and the digging arm 7, the supporting plate 6 and the digging arm 7 are both provided with spring clamping seats 12, and two ends of the spring 11 are fixed by the spring clamping seats 12. This embodiment has two springs 11, the springs 11 being in a compressed state in the state shown in fig. 1.
The rotating shaft II 4-1 is rotated through the hand wheel 4-3, so that a first steel cable 8-1 connected with the swinging block 1 is tightened, the swinging block 1 drives the supporting plate 6 and the digging arm 7 to swing upwards, meanwhile, a second steel cable 8-2 connected with the digging arm 7 is loosened, and the digging arm 7 extends out along the supporting plate 6 under the action of the telescopic device 2; and (3) reversely rotating the hand wheel 4-3, enabling the supporting plate 6 and the digging arm 7 to fall back, and enabling the second steel cable 8-2 to pull the digging arm 7 to retract so as to compress the telescopic device 2. Due to the self gravity of the digging arm 7 and the supporting plate 6 and the arrangement of the reset mechanism between the swinging block 1 and the connecting rod 9, the digging arm 7 and the supporting plate 6 can be driven to quickly and automatically fall and reset, and meanwhile, the hand wheel 4-3 drives the rotating shaft II 4-1 to wind the second steel cable 8-2, so that the digging arm 7 realizes the action of retracting the raking claw. A positioning mechanism is arranged between the hand wheel 4-3 and the connecting rod 9, for example, a positioning clamp is arranged on a convex part or a jackscrew and other mechanical structures, so that the hand wheel 4-3 can be positioned, when the digging arm 7 and the supporting plate 6 are lifted upwards, the positioning can be realized, other tools can be conveniently used for loading silt or garbage into the dustpan, and the work blockage caused by the limitation of the force of the digging arm 7 is avoided.
Because the spring 11 is in a compressed state when the whole device is not operated, the digging arm 7 can extend forwards when the second steel cable 8-1 on the fixing ring 14 is loosened and extended, and the digging arm 7 can contract backwards when the second steel cable 8-2 is tightened and shortened; when the second steel cable 8-2 on the fixing ring 14 is loosened and extended, the first steel cable 8-1 in the fixing hole 1-4 on the swinging block 1 at the other end is tightened and shortened, at the same time, the supporting plate arm 1-3 on the swinging block 1 can drive the upper cover (comprising the supporting plate 6 and the excavating arm 7) of the whole dredging device to be opened, and similarly, when the second steel cable 8-1 on the fixing ring 14 is tightened and shortened, the first steel cable 8-1 in the fixing hole 1-4 on the swinging block 1 at the other end is loosened and extended, at the same time, the supporting plate arm 1-3 on the swinging block 1 can drive the upper cover of the whole dredging device to be closed, namely, the excavating arm 7 extends out while the upper cover is opened, and the excavating arm 7 retracts while the upper cover is closed, so that the operation process of raking sundries and sludge in the inspection well into the bucket is realized.
The dustpan 5 is provided with the water leakage hole 3, and the water leakage hole 3 is a tapered hole with a large diameter and a small diameter, so that redundant water in the sludge can be leaked, the weight is reduced, the lifting is convenient, and the sludge can be prevented from leaking from the water leakage hole 3. The front end hook part of the digging arm 7 is composed of a plurality of rake teeth arranged in parallel, so that the digging is convenient, and the resistance is reduced. The dustpan 5 becomes thinner gradually from back to front, and the digging arm 7 is matched with the dustpan 5. The root part (namely the position close to the connecting rod 9) of the dustpan 5 is thick, the structural strength of the dustpan is ensured, the front end of the dustpan is thinned, the weight of the dustpan can be reduced, the operation is convenient, and the front end bent hook part of the excavating arm 7 is positioned on the upper part of the front end of the dustpan 5 after being reset.
During operation, the part of the dredging device is placed at the sludge, the hand wheel 4-3 is rotated to one side, the upper cover of the dredging device is opened at the moment, the hand wheel 4-3 is rotated to the other side, the sludge is dug into the scooping bucket 5 when the upper cover is gradually closed, the processes are repeated, when the scooping bucket is filled with the sludge, the whole device is slowly lifted upwards and taken out, redundant water in the taking-out process leaks from the water leakage hole 3, the dredging process is completed at the moment, and the sludge is poured out after the whole device is taken out to prepare for dredging again.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
