The position of patch.
Driving motor drive agitating shaft 5 rotate, agitating shaft 5 drive stirring rod 52 rotation therefore realize to sludge, haydite and
The uniform stirring of stalk, due to top stirring rod 52 rotate when, drive rotate gear 521 rotate, and rotate gear 521 with
Gear teeth meshing on spacing collar 53, therefore rotate gear 521 drives stirring rod 52 that rotation occurs, and passes through four transmission gears
522 transmission, so that rotation occurs for four agitating shafts 5, helical blade 523 is rotated, so that stirring is more evenly, improves hair
The effect of ferment.
Agitating shaft 5 drives striker plate 6 to rotate during rotating, when striker plate 6 turns to through-hole 61 and the company of discharge port 13
When logical, guide block 75 is just made to realize that guide block 75 moves down with the cylindrical cam structure that sliding slot 54 is constituted, so that 75 band of guide block
Dynamic push rod 74 moves down, and realizes that slide plate 71 moves down.Slide plate 71 and feed box constitute piston structure, therefore when slide plate 71 moves down, lead to
Crossing material guide port 72, discharge port 13 and through-hole 61 will stir, in mixed mixed material importing discharge tank 7.
With the rotation of agitating shaft 5, discharge port 13 is gradually staggered with through-hole 61, and sliding slot 54 rotates at this time, from
And guide block 75 is moved up, it drives slide plate 71 to move up, squeezes out the mixed material on 7 top of charging basket, open sealing cover, so that discharging
Mixed material in bucket 7 is discharged from discharge gate 73.
Spice is carried out to sludge, haydite and stalk using the material blending device to have the effect that
1. being enabled to by being just stirred to it during sludge, haydite and stalk are added into agitator 1
Less material is stirred, and compared with being stirred a large amount of sludge, haydite and stalk, enables to stirring more evenly,
To improve the ferment effect of subsequent handling, so that the fertility of the composite microbe fertilizer of preparation is stronger；
2. by the gear teeth on spacing collar 53 and rotate gear 521 engage and the intermeshing of transmission gear 522,
Stirring rod 52 be can be realized while rotating under agitating shaft 5 drives, rotation occurs, so as to sludge, haydite and stalk
Stirring more evenly, so as to improve ferment effect；
3. making mixed mixture in agitator 1 by being connected to discharge port 13 for 61 interval of through-hole on striker plate 6
Material is exported from discharge port 13, therefore can be avoided the excessively bad situation of caused mixed effect of the material accumulation in agitator 1
Occur；
4. being not easy to be discharged from discharge port 13 since sludge has certain viscosity, therefore by setting discharge tank 7, and make
Discharge tank 7 and slide plate 71 constitute piston barrel structure, when realizing that slide plate 71 moves down, generate suction, mixed mixed material is inhaled
Enter in discharge tank 7, realizes the discharging of mixed material.
