Abstract
The utility model relates to a swing arm type arc-shaped grid dirt removing machine, particularly a dirt removing mechanism used for dredging suspending floating materials of large granules in shallow grid trenches. The utility model comprises a machine frame, a slag removing mechanism, a flushing device and a rotating rake which is provided with long slots along the length direction and is hinged on the machine frame through pin shafts matched with the long slots, wherein the machine frame is fixed with a transmission mechanism, an output shaft of which is sheathed with a crank; the other end of the crank is hinged with the rotating rake. The utility model adopts the principle of a crank/slide rod mechanism that an output shaft of a speed reducer of the transmission mechanism drives the crank to rotate in the single direction through the crank /slide bar mechanism. The apex trace of the rotating rake is waist-shaped curves, namely, the running trace of rake teeth. The number of the waist-shaped curves is two, and the waist-shaped curves are approximate to a circular arc and are not overlapped so as to realize the actions of extending when advance and retracting when return of the combined rotating rake. The running velocity of the end point of the waist-shaped curve is close to zero so as to realize the stop action of the combined rotating rake. Because the swinging amplitude of the rotating rake is big, the slag removing mechanism can automatically remove slag under the action of the gravity of the slag removing mechanism.
Description
Technical field
The utility model relates to and is used for the scrubbing mechanism that more shallow grid canal is fished for bulky grain suspension, floating substance.
Background technology
Existing Arc grid spotter mainly contains following three kinds: 1. swing-arm type.This kind Arc grid spotter is simple in structure, moves singlely, and operation troubles is few, and maintenance is convenient, but its rotating diameter is big, and required running space is big, and inconvenience is in indoor use.2. flexible rake formula.This kind Arc grid spotter need adopt the electric hydaulic driving mechanism, its structure, control system complexity.3. swing arm.Existing swing arm Arc grid spotter adopts the crank and rocker mechanism principle, and is simple in structure, and maintenance is convenient, and running space is little.But it is limited by endplay device, and its rake teeth amplitude of fluctuation is little.
The utility model content
The purpose of this utility model is that it is little to design a kind of running space, simple and reasonable, the swing arm Arc grid spotter that is easy to safeguard at the deficiency of existing Arc grid spotter existence.
The utility model comprises frame, slag removing mechanism, flusher, commentaries on classics rake, offer elongated slot at the commentaries on classics rake along its length direction, changeing rake is hinged and connected on the frame by the bearing pin that cooperates with this elongated slot, on frame, fix a transmission mechanism, output shaft socket one crank of transmission mechanism, the other end of crank is hinged with the commentaries on classics rake.
The utility model adopts slide crank linkage principle, and the reductor shaft drives crank and makes folk prescription to gyration by the slide crank linkage in the transmission mechanism.Changeing rake summit track is a waist ogee curve s, i.e. rake teeth running orbit.The waist ogee curve s is two sections approximate circular arcs, and two sections curves do not overlap, and realizes that the process of changeing the rake combination is stretched out, backhaul withdrawal action.The waist ogee curve s distal point speed of service approaches zero, realizes changeing the action that stops of rake combination, and the amplitude of fluctuation of changeing rake is big, and slag removing mechanism is automatic slag removal under the self gravitation effect.
The utility model impact and noise are less, and commentaries on classics rake amplitude of fluctuation is big, operates steadily during load, and simple in structure, compact, running space is little, and maintenance is convenient, and can realize hermetically sealed operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 arrives structural representation topmost for changeing rake.
Among the figure, 1 transmission mechanism, 2 seal closures, 3 change rake, 4 bearing pins, 5 frames, 6 slag removing mechanisms, 7 flushers, 8 elongated slots, 9 cranks, 10 grizzly bars, 11 slag notches, 12 bearing pins.
Specific embodiment
On the top of changeing rake, offer elongated slot 8 along its length direction, the bearing pin 4 that in elongated slot 8, cooperates, in the through hole that is set in frame 5 of bearing pin 4, formation is hinged, fixed conveyor mechanism 1 on frame 5, output shaft socket one crank 9 of transmission mechanism 1, crank 9 is hinged with commentaries on classics rake 3 by another group bearing pin 12.
Claims (1)
1, swing arm Arc grid spotter, comprise frame, slag removing mechanism, flusher, commentaries on classics rake, it is characterized in that changeing rake and offer elongated slot along its length direction, changeing rake is hinged and connected on the frame by the bearing pin that cooperates with this elongated slot, on frame, fix a transmission mechanism, output shaft socket one crank of transmission mechanism, the other end of crank is hinged with the commentaries on classics rake.
