Description
Technical field
The utility model belongs to tobacco seedling and cultivates seeding technique field, and in particular to a kind of structure is simple, sows gradation
Hand seedling cave seeding apparatus with high accuracy with gradation function.
Background technique
Theoretically: Nicotiana tabacum seed, one plant of flue-cured tobacco can produce 12 ~ 15g or so, about 150000 seeds.1g
Tobacco seed has 10000 ~ 13000, and mass of 1000 kernel 0.06g~0.09g is differed.Therefore, the volume of tobacco seed is very small.
In practical scientific research and testing, especially in the research of breeding of new variety, needs many kinds being planted in crop field and observe.
This usually too busy to get away the first step " nursery ".Current nursery is all floating seedlings, and seed or pelleted seed are directly cast to floating disc
Kong Zhong, since seed is smaller, it is more troublesome, time-consuming when leading to sowing to be not easy to control quantity, also often results in every hole 3 ~ 6
Grain or even more than 10, on the one hand waste a large amount of seed, on the other hand also add to, the difficulty of final singling, frequently result in weak
Seedling.In the case that the seed quantity of especially breeder's offer is very limited, unnecessary loss may also will cause.
Therefore, develop that a kind of structure is simple, sowing gradation seed seeder with high accuracy is the key that solve the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of structures simply, the sowing gradation hand with high accuracy with gradation function
Dynamic formula seedling cave seeding apparatus.
Purpose of the utility model is realized as follows: including seed storehouse, control seed valve, handle, Dao Boguan, driving mechanism
With sorting grain mechanism, seed valve is controlled in the bottom setting in the seed storehouse, divides classer in the lower part setting of the control seed valve
Structure is managed, the middle and upper part setting handle in the seed storehouse in the setting instructor in broadcasting on seed mouth that goes out of the sorting grain mechanism, on handle
The driving mechanism for extending downward into sorting grain mechanism lower part is set, and the driving mechanism is sequentially connected control seed valve, divides classer
Structure makes driving mechanism move cooperation with control seed valve, sorting grain mechanism respectively；Wherein, the sorting grain mechanism includes separator plate, divides
Shell is selected, on the separator plate suitable circular configuration is matched by shaft coaxial arrangement therewith and sorts shell, and between separator plate and sorting shell
Gap cooperation makes shaft that separator plate be driven to rotate in sorting shell, and the separator plate circumference is all provided with several seed selection slots, the sorting shell
Top be arranged into seed mouth, seed mouth is provided in bottom.
Compared with prior art, the utility model has following technical effect that
Each seed selection slot is dimensioned to be packed by the utility model by the way that seed selection slot is arranged on separator plate
1 ~ 2 tobacco seed size, when in use, the requirement to operator is extremely low, as long as according to the mode of operation of the utility model,
The hole program request of one floating disc can be completed soon, be solved in traditional seeding method because being not easy by the hole-specifically method of program request
Controlling quantity leads to the problem of often resulting in 5 ~ 6 or even more than the 10 waste a large amount of seeds in every hole when sowing；The present apparatus is being broadcast
Energy self-seeding seed when kind sorts seed, and easy to use, it is time saving and energy saving to sow；When the traditional manual sowing of solution, often broadcast
One seedling cave of kind needs to repeat in container the case where taking seed, reduces sowing labor intensity, greatly improves sowing efficiency,
And after emerging, each hole is essentially 1 ~ 2 young plant, and tobacco seedlings are healthy and strong, final singling when saving of work and time.
