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 the special twin-stage underflow pump of removed-earth jet sowing machine and removed-earth jet sowing machine that one is applicable to carry sticky material (mud etc.).
Background technology
Nowadays, removed-earth jet sowing machine progressively instead of dry spraying machine and the concrete pump status in greening side slope construction, to some extent solves that dry spraying machine efficiency is low, construction cost is high, artificial many and delivery pump moves inconvenience, the shortcoming of construction risk.So-called removed-earth jet sowing machine is by grass-seed, shrub, arbor kind etc., with water-loss reducer, adhesive, vegetable fiber and planting soil and fertilizer etc., stirring the mixed serum being mixed into thickness in filling with water, is sowed grass seeds by duster in side slope with special underflow pump.Due in mixed serum containing water conservation, jointing material and various nutrient, ensure that the water needed for plant growth and other nutriment source, so plant can healthy, promptly grow up, saved the curing cycle of conventional method simultaneously! Be suitable for large-area greening to sow grass seeds by duster, particularly add high order granule technology, more adapt to comparatively arid and lack the area of pouring facility, and the hydrophobic reactant of high order granule, and the cellular granule formed, preventing rain wash ability is strong especially! Therefore, the place greening that removed-earth jet sowing machine is used to rock, hard soil, sandy soil, poor and barren land, acid ground, arid tract, seashore put forward the plant growth difficulties such as dam is sowed grass seeds by duster, and is also widely used on the engineering fields such as highway, high-speed railway greening side slope, mine recovery, ecological recovery, desert treatment simultaneously.
At present, existing removed-earth jet sowing machine main pump because of impeller rotation direction, impeller quantity, and on two-stage pump, the position of feeding mouth is different, in use there is a lot of drawback, specific as follows: 1, spray seeder main pump is single-stage impeller mostly, and lift is generally lower; 2, spray seeder main pump impeller operationally from its direction of rotation viewed from shaft coupling end be dextrorotation, identical with the rotation direction of engine as diesel engine, therefore can only be connected at two ends on the same axis by shaft coupling or belt with engine, namely the installation site of pump and engine (as diesel engine) can only be direct-connected and be arranged on belt pulley and shaft coupling two ends, and can not parallelly install, add spray seeder overall length and floor space; And load can be made excessive because entering the stuck impeller of bulky grain in the pump housing by the gun iron link of shaft coupling like this, thus damage slush pump or diesel engine; Although 3, existing spray seeder have employed two-stage pump, but because impeller rotation direction and the position that enters pumping hole limit, add pan feeding auger and the synchronized case of commutation, more complicated in structure, thus add breakdown maintenance point and kinetic equation loss, reduce lift and the service life of spray seeder simultaneously.
