Description
Technical field
The utility model belongs to seeding technique field, relates to a kind of tobacco coating seed seedling-raising seeder of accurate fixed number.
Background technology
Tobacco coating seed is the spherical of about diameter 2.5mm, and first the plantation of tobacco needs capsuled seed to be seeded into after growing seedlings in the grid plate-like seedling-cultivating tray of disjunctor and to be transplanted in field.As adopted manually, short grained capsuled seed is inserted in seedling-cultivating tray by grain, labour intensity is large and insert irregularly, easily wastes capsuled seed, and production efficiency is too low, and therefore, people have invented tobacco coating seed seedling-raising seeder.
For example, publication number is the technology that discloses " a kind of tobacco capsuled seed seeder " by name in the Chinese patent of CN2509830, this seeder by housing, control gate valve part, enter tray salver or enter plate part, seedling-cultivating tray forms, wherein, on housing, aspect is the surface with recess, this surface is provided with little large trapezoidal row pilot trench under some, is provided with the flaw hole of arrangement in trapezoidal row pilot trench; Control gate valve part and in the mode of pull, be located at the bottom of housing, on it, by a fixed head, be fixedly connected with the control lock bar corresponding with top row pilot trench, each is controlled on lock bar and also arranges and be provided with the lower seed hole equating with flaw hole number, control the pull return of gate valve part and controlled by elastic component, its underpart is provided with for putting entering tray salver or entering plate part of seedling-cultivating tray.
Adopt the tobacco coating seed seedling-raising seeder of such technology certainly can use, but have the following disadvantages:
A, that it controls gate valve part is too simple, and structure is for " to be provided with the flaw hole of arrangement in trapezoidal row pilot trench; Control gate valve part and in the mode of pull, be located at the bottom of housing, on it, by a fixed head, be fixedly connected with the control lock bar corresponding with top row pilot trench, each is controlled on lock bar and also arranges and be provided with the lower seed hole equating with flaw hole number ".When controlling capsuled seed whereabouts, likely a plurality of seeds are fallen the same lattice of seedling-cultivating tray from same flaw hole simultaneously, can cause the waste of seed.
B, its poly-seed device are broad categorizing style, and structure is " on housing, aspect is the surface with recess, and this surface is provided with little large trapezoidal row pilot trench under some ", is being assigned to likely skewness of each flaw hole, can cause broadcast leakage.
To sum up, the control of the tobacco coating seed seedling-raising seeder of technology is accurate not enough like this, and result of use is desirable not enough.
