The slider cover 212 is further provided with a second protrusion 2122, the second protrusion 2122 is also disposed in the sliding slot 10, the supporting inclined surface 241 when the handle trigger 24 is stressed abuts against the second protrusion 2122 and drives the entire slider cover 212 to move, meanwhile, the slider cover 212 drives the main body portion 211 to move, and the main body portion 211 drives the pull wire 30 to move, thereby controlling the opening and closing of the discharge hole 51.

The adjustment assembly 26 is used to control the movement amount of the slider 21 (i.e., to limit the maximum opening of the discharge port 51). Specifically, referring to fig. 4, 5, 8 and 9, the adjustment assembly 26 includes an adjustment wheel 261 and an adjustment knob 262 disposed coaxially with the adjustment wheel 261; the adjustment wheel 261 is provided on the sliding track of the chute 10, and has a plurality of latches 2611, and the distance between the latches 2611 and the axis of the adjustment wheel 261 gradually increases in the direction of one rotation along the axis of the adjustment wheel 261, that is, the adjustment wheel 261 has a turbine shape and a surface having a substantially involute curve. When the body portion 211 of the slider 21 abuts on different latches 2611, the movement amount of the wire 30 is different, and the maximum opening degree of the discharge port 51 is also different. The control device 100 for the spreader can control the opening degree of the discharge port 51 to be fully opened from closing, each latch 2611 corresponds to one opening degree, the opening degree is the same as the number of the latches 2611, the adjustment range is wide, the discharge port 51 can be stable at each opening degree through the structure of the latches 2611, and the sliding gear does not influence the discharge speed of the discharge port 51 due to the shaking of the spreader.

Further, when handle trigger 24 is unstressed, second end 2112 of body portion 211 is spaced a distance from the maximum radius position of adjustment wheel 261. Thus, the adjustment assembly 26 may be rotated clockwise or counterclockwise, setting the position of the adjustment wheel 261.

As shown in fig. 10, the discharging hole 51 has three through holes arranged in a fan shape around the same axis. The hatch door assembly 6 is rotatably arranged at the bottom of the hopper 5, the hatch door assembly 6 is provided with a blanking port 61, the blanking port 61 has the same size as the discharging port 51, and when the hatch door assembly 6 rotates and moves, the discharging port 51 is overlapped or partially overlapped with the blanking port 61.
