As a further improvement of the present invention, the driving device is a telescopic cylinder, and the transmission device includes an upper link, a middle link, a lower link and a rack;

The extension rod of the telescopic cylinder is hinged with the rear end of the upper link, the front end of the upper link is hinged with one end of the middle link, and the other end of the middle link is hinged with the rear end of the lower link. a rear end of the rod is hinged to the rack, and a middle portion of the middle link is also hinged to the main arm or the housing;

a guiding member for restraining the rack from moving back and forth relative to the housing is further disposed in the housing;

The rack drives two dross simultaneously to close or open:

a first gear and a second gear are disposed in the housing, and the two slags are respectively connected and connected to the two gears, and the rack is disposed between the first gear and the second gear, and both sides of the rack are provided a tooth, one side of the rack meshes with the first gear, and the other side meshes with the second gear;

Alternatively, the rack drives the two dross simultaneously by the following structure:

One of the two slags is coupled to a gear that meshes with the rack, and the gear drives the other slag synchronously by the synchronizing mechanism.

As a further improvement of the present invention, the first gear and the second gear are each connected to the corresponding dross through a rotating shaft.

Beneficial effect

Compared with the prior art, the present invention has the following positive effects: mainly for the current KR method desulfurization, ladle dumping, driving the slag slag of the front end by the rear driving device to avoid the front end of the main arm being too bulky The utility model has the advantages of improving the efficiency of the slag, so that the device has the advantages of high slag efficiency and less iron during the pre-clearing period, and the utility of the slag slag machine being flexible and quick, and the slag speed is fast in the late Qing Dynasty.

BEST MODE FOR CARRYING OUT THE INVENTION

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings:

1 and 2, a link type rotary slag cleaning device includes a main arm 1 and a casing mounted at a front end of the main arm 1, and the lower end of the casing is provided with two dross which are rotatable relative to the casing. Also included is a drive device and a transmission device that is mounted in the middle or rear of the main arm 1, and the drive device drives the two dross to be simultaneously gathered or opened by the transmission.

The driving device is a telescopic cylinder 2, the transmission device includes an upper link 3, a middle link 4, a lower link 5 and a rack 6;

The extension rod of the telescopic cylinder 2 is hinged with the rear end of the upper link 3, the front end of the upper link 3 is hinged with the upper end of the middle link 4, and the lower end of the middle link 4 and the rear end of the lower link 5 Articulated, the rear end of the lower link 5 is hinged to the rack 6, and the middle portion of the middle link 4 is also hinged to the main arm 1 or the housing;

A guide member that restrains the rack 6 from moving back and forth relative to the housing is also provided in the housing.

The rack 6 drives two dross while being gathered or opened:

As shown in FIG. 3, the first gear 9 and the second gear 10 are disposed in the housing, and the two slags are respectively connected to and connected to the two gears, and the rack 6 is disposed on the first gear 9 and the second gear 10. Between the two sides of the rack 6 have teeth, the side of the rack 6 meshes with the first gear 9 and the other side meshes with the second gear 10; the first gear 9 and the second gear 10 respectively It is connected to the corresponding dross by a rotating shaft 7.

Alternatively, the rack 6 drives the two slags to simultaneously gather or open by the following mechanism: one of the two slags is connected with a gear that meshes with the rack 6, and the gear is driven by a synchronization mechanism. A dross synchronously rotates in reverse, and the input end and the output end of the synchronizing mechanism rotate in opposite directions, and can be realized by a structure such as a gear and a timing belt.

When the slag is slag, the telescopic cylinder 2 contracts, pulls the upper link 3 backward, drives the middle link 4 to rotate, the lower end of the middle link 4 pushes the lower link 5 forward, and the lower link 5 pushes the rack 6 forward to drive the two The slag is turned and closed.

When the slag is discharged, the telescopic cylinder 2 is extended, the upper link 3 is pushed forward, the middle link 4 is driven to rotate, the lower end of the middle link 4 pulls the lower link 5 backward, and the lower link 5 pulls the rack 6 backward to drive The two slags are turned and opened to slag.

The device is arranged on the swingable frame, and the swingable frame is connected to the base by the swing support, and the base is fixedly connected with the platform, so that the main arm 1 and the landing arm can be lifted and retracted. Therefore, after the driving device is disposed on the rear side of the main arm 1, the driving torque required for the main arm 1 to rise and fall can be reduced, and the moment of inertia required for the swingable frame to be rotated can be reduced, so that the device has both the slag The machine has the advantages of high slag efficiency and less iron in the pre-clearing period, and the advantages of the slag slag machine being flexible and the slag speed in the late Qing Dynasty.
