Composite scattering machine

The invention relates to a composite scattering machine which comprises a rack and a hopper. The hopper is arranged on the rack. A feeding opening is formed in the upper end of the hopper, and a discharging opening is formed in the lower end of the hopper and provided with a discharge valve. A filter sieve and a scattering device are sequentially arranged in the hopper from top to bottom. The scattering device is composed of a supporting plate and scattering impellers. The two ends of the supporting plate are fixed to the side walls of the left side and the right side in the hopper. The two tofour scattering impellers rotating in the same direction are horizontally arranged on the supporting plate at intervals. A spring door is arranged at the position, between the filter sieve and the supporting plate, of the left side wall of the hopper. By means of the structure, large or ultra-large soil blocks can be crushed, sieved and stirred in the hopper, the problem that the large or ultra-large soil blocks block th
