Preferably, the tail parts of the two sides of the second material blocking plate are provided with third material blocking plates.
By adopting the scheme, the third material baffle plate can play a role in preventing coal scattering for the second time.
Preferably, the third material baffle plate is vertically arranged and is parallel to the width direction of the conveying belt.
By adopting the scheme, the third retainer plate is vertically arranged and is parallel to the width direction of the conveying belt, so that the working surface of the third retainer plate is larger in contact with the coal, and the effect of preventing the coal from scattering can be better played.
Preferably, one side of the coal hopper close to the conveyor belt is inclined towards the conveyor belt.
By adopting the scheme, the coal falls into the coal hopper more conveniently due to the inclined arrangement.
Preferably, the coal hopper is provided with a hopper cover which is opened towards one side of the conveyor belt, and the height of the hopper cover is higher than that of the coulter.
By adopting the scheme, the bucket cover prevents coal from jumping out, and the height of the bucket cover is higher than that of the coulter, so that the coal can be prevented from jumping out.
The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the four-bar linkage trough angle-variable bilateral coal plough has good coal falling prevention effect.
