[0007] The spade is vertically arranged on the driving shaft through an adjusting screw.

[0008] A triangular reinforcing frame is arranged below the fixed cross beam.

[0009] The two sides of the receiving hopper are provided with guide plates, and the receiving hopper is inserted between the two guide plates.

[0010] The spade mechanism for low-pressure casting sealing ring cleaning has the following beneficial effects:

[0011] 1. The utility model discloses a two spades, and sets up connecting rod at both ends of spade, and the connecting rod of two spades is driven synchronously through a drive arrangement, realizes the effect of bidirectional scraping seal ring and residual aluminum liquid at the bottom of mould feed inlet, drive arrangement drives the reciprocating motion of connecting rod, and two spades cooperate with each other, realize the function of scraping the residue at the bottom of mould in two directions, and spade assembly is driven through bidirectional connecting rod, one spade cutting edge is pasted flat with the bottom of mould, and the other spade is lowered synchronously.

[0012] 2. The utility model discloses the back of spade is limited through the adjusting screw of installation on the drive shaft, and spade stands on the drive shaft, when scraping the residue at the bottom of mould through the cutting edge of standing, spade pressure is passed on the back drive shaft through adjusting screw, to promote the strength of spade scraping, thereby promoting the cleanliness of scraping at the bottom of mould.

[0013] 3. The utility model discloses the bottom of spade assembly is provided with receiving hopper, and the residue such as seal ring and aluminum liquid falling in the scraping process falls in the bottom receiving hopper through both sides guide plate, and the receiving hopper is in the pull -out mode, and the manual cleaning of residue is convenient.
