Heavy plate feeder for mineral aggregate

The heavy type plate feeder comprises a conveying belt, two baffles are arranged above the conveying belt, the length direction of the baffles is consistent with the length direction of the conveying belt, and a supporting baffle and a power assembly for controlling the baffles to move in the width direction of the conveying belt are installed on the ground. A mounting plate sliding in the length direction of the baffle is slidably connected to the top of the baffle, sleeves are slidably connected to the mounting plate, a main rod is slidably inserted into the two sleeves, limiting springs are connected to the two ends of the main rod, and the ends, away from the main rod, of the limiting springs are connected with the sleeves; the number of the deflector rods is at most two, the main rod is further provided with a transmission piece for driving the deflector rods to move so as to scatter mineral aggregate, and a scatter hydraulic cylinder for driving the sleeve to reciprocate in the length direction of the b
