The reciprocating mechanism 12 comprises an eccentric wheel 20, a transmission rod 21 and a driving motor (the driving motor is not shown in the figure), the reciprocating mechanism 12 can drive the material pressing piston 2 positioned in the metering bin 1 to do reciprocating lifting motion, a side feeding bin opening 7 is further formed in the side wall of the metering bin 1 on one side of the lifting motion path of the material pressing piston 2, and the side feeding bin opening 7 is communicated with the side opening of the material tank 9. The arc-plate-shaped opening and closing split cover 4 is arranged below the discharging bin opening 10, the opening and closing split cover 4 comprises two split transverse covers 15, and a connecting vertical plate 8 extends upwards from one side of each split transverse cover 15; a horizontal cross column 13 is fixedly arranged on the outer side wall (the side wall far away from the side opening) of the measuring bin 1, the proximal end points of the two groups of two connecting rods 3 are hinged on the same point of a transmission rod 21 of the reciprocating mechanism 12, the distal end points of the two groups of two connecting rods 3 are rotatably arranged on the cross column 13, so that the two groups of two connecting rods 3 form a quadrangle with variable interior angles, the connecting line between the proximal end point and the distal end points is a symmetry axis, and the two groups of two connecting rods and the corresponding cover bodies thereof are mutually symmetrical about the symmetry axis; in addition, the two connecting vertical plates 8 are respectively and correspondingly fixedly connected with the distal end parts of the two connecting rods 3, so that the two connecting rods 3 are fixedly connected with the cover body.
