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 screening stirring tank body and special-purpose removed-earth jet sowing machine of exempting from.
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 slush pump it is sowed grass seeds by duster on side slope.Owing to contain 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! Therefore, removed-earth jet sowing machine is applicable to rock, hard soil, sandy soil, poor and barren land, acid ground, arid tract, seashore and proposes the place greening of the plant growth difficulties such as dam and sow grass seeds by duster, and is widely used in simultaneously on the engineering fields such as highway, high-speed railway greening side slope, mine recovery, ecological recovery, desert treatment.
At present, existing spray seeder does not all have screening system, and in the removed-earth jet sowing machine work progress, for normally carrying out of guaranteeing to construct, flow particles through pump or nozzle is had strict demand, and in general, the overcurrent particle requirement of pump is within 10 millimeters, the overcurrent particle of nozzle then requires in 20 millimeter, and this particle size that all requires material to comprise that soil waits must be controlled in 10 millimeters.Therefore, in engineering construction, must fully sieve the materials such as soil size at 10 millimeters with after interior first, could in the spray seeder tank body, feed in raw material, this screening operation, taken a large amount of artificial (approximately need 8-10 people to sieve soil and could satisfy construction), that have or simply native with the forklift sieve, all increased greatly construction cost.And in the situation of raining, wet soil can't sieve at all, has then greatly affected duration and project progress, brings very large trouble to construction.The soil that sieved is simultaneously also unavoidably mixed the bulky grain around the mound in tank body with forklift or artificial loading the time, cause pump or nozzle place to stop up, even damage pump case or impeller etc., thereby affected construction speed, reduce efficiency of construction, even also can improve construction cost.
