Description

Drive plate-like straight knife formula combined seed and fertilizer drill

Technical field

The utility model relates to a kind of sower, particularly a kind of driving plate-like straight knife formula combined seed and fertilizer drill.

Background technology

At present, the domestic large-scale no-tillage seeding machine that generally adopts has three kinds: the pull-alongs no-tillage seeding machine of 1 external import; The 2 domestic banded rotary tillage formula no-tillage seeding machines of development voluntarily; 3 power disc type no-tillage seeding machines.

The operation principle of the pull-alongs no-tillage seeding machine of external import is: rely on increase complete machine weight that table roller is suppressed during tractor-drawn is advanced and bury, cut off stalk or weeds, loosen the soil the disc type plough of back water furrow planting under the effect of complete machine weight simultaneously.Its advantage is: 1. adopts driven disk formula water furrow planting device, do not need the power input, and simple in structure, easily manufactured; 2. it is little to show the soil rate of breaking ground; Its shortcoming is: 1. complete machine weight can not alleviate, and mating power is big, and general tractor is more than 100 horsepowers; 2. the depth as shallow of ditching can only shallowly be applied fertilizer, can not fertilizer deep placement; 3. seed manure easily burns seed with bed when adopting homemade chemical fertilizer fertilizing amount big; The kind of easily drying in the air when 4. disc type water furrow planting device runs into stalk forms the disconnected ridge that is short of seedling; 5. only suit in the wide large tracts of land plot operation in Xinjiang and region, the Northeast.

Banded rotary tillage formula no-tillage seeding machine is to develop on the basis of rotovator, adopt the banded rotary tillage ditching sowing of rotary cutter, reach the order ground of where sowing that rotary tillage, after planting show as trench sowing, its advantage is: 1. adopt the banded rotary tillage of power rotary cutter, complete machine weight can alleviate; 2. direct no-tillage or minimal till seeding operation on the regional straw-returning ground that yields two crops a year; 3. the patented technology that adopts plough to be clipped among the rotary cutter can effectively solve blockage problem; Its shortcoming is: it is big 1. to show the soil rate of breaking ground, and very difficult realization rate≤30% of breaking ground only belongs to the category of minimal tilling; 2. after planting show as trench sowing, can not satisfy the custom planting patterns of peasant household's flat planting; 3. stationary performance is relatively poor during the facility operation; 4. the easy hilling of facility influences trafficability characteristic than the operation of wetland piece the time.

The power disc type no-tillage seeding machine adopts the banded cultivated soil of dredging of power cutting disc, cuts off stalk or weeds, and seed manure plough trench digging ferti-seeding after planting shows as flat planting, and its advantage is: the degree of depth depth of 1. ploughing thin soil is adjustable; 2. to show the soil rate of breaking ground little, reached≤30% no-tillage requirement; 3. after planting the face of land is more smooth, can satisfy the custom planting patterns of peasant household's flat planting; 4. compare with banded rotary tillage formula no-tillage seeding machine with the pull-alongs no-tillage seeding machine, decrease on power consumption and the complete machine weight; Its shortcoming is: 1. power cutaway disk cutter and soil contact are long-pending big, swing is only arranged, and shear action are very little, increase power consumption; 2. adjacent two unremitting cutaway disk cuttves form the big osculum of closed at both ends, easily carry the uncultivated land soil block in the operation secretly; The swing of 3. unremitting cutaway disk cutter causes sowing ploughing the band move left and right and become flexible in the ranks; 4. the weight of cutaway disk cutter and manufacture difficulty are big, and especially breach puts the first edge on a knife or a pair of scissors; Only can whole (two semicircles) change when the 5. breach of cutaway disk cutter stalk easy to hang and grass, and wearing and tearing and damage.

Summary of the invention
