Description
Technical field
The invention belongs to the field of mechanical technique of sowing grass seeds by duster of the plants such as greening side slope plantation draft, shrub, arbor, particularly relate to a kind of special-purpose twin-stage underflow pump of removed-earth jet sowing machine and removed-earth jet sowing machine that is applicable to carry sticky material (mud etc.).
Background technology
Nowadays, removed-earth jet sowing machine has progressively replaced dry spraying machine and the concrete pump status in the greening side slope construction, has solved to a certain extent that dry spraying machine efficient is low, construction cost is high, artificial many and delivery pump moves inconvenience, the shortcoming that construction is dangerous.So-called removed-earth jet sowing machine is with grass-seed, shrub, arbor kind etc., with water-loss reducer, adhesive, vegetable fiber and planting soil and fertilizer etc., is mixed into the mixed serum of thickness with water in stirring filling, with special-purpose underflow pump it is sowed grass seeds by duster on side slope.Owing to containing water conservation, jointing material and various nutrient in the mixed serum, guaranteed the required water of plant growth and other nutriment source, so plant can be healthy, promptly grow up, saved simultaneously the curing cycle of conventional method! Be suitable for large-area greening and sow grass seeds by duster, particularly add high order granule technology, more adaptation is comparatively arid lacks the area of watering facility, and the hydrophobic reactant of high order granule, and the cellular granule that forms, and the preventing rain wash ability is strong especially!
