Description

The seeder of microphyte seed for experiment

Technical field

The utility model relates to a kind of microphyte planting seed device, relates in particular to the minute seeds seeding appliance using in the time that plant tissue culture is tested.

Background technology

At present, in the time that Plant Tissue Breeding relates to minute seeds, generally adopt tweezers or rifle head to sow.While adopting tweezers or the sowing of rifle head for sowing dry seeds, effect is all right, but the wet kind of period of the day from 11 p.m. to 1 a.m soaking in sowing just can only be used the sowing of one one of tweezers, and this method is length consuming time not only, and efficiency is low, and operating personnel are very tired out.While operation under aseptic condition, above these two kinds of methods all can increase because of the long microbiological contamination rate that causes of operating time, and severe patient affects growth and development of plants.

Summary of the invention

The purpose of this utility model is the problem existing for prior art, provide a kind of easy to use, sowing evenly, reduce microbiological contamination rate, be convenient to the seeder of the experiment microphyte seed of planting on a large scale microphyte seed on medium.

For achieving the above object, the utility model is by the following technical solutions:

Experiment of the present utility model mainly comprises seeds chamber, piston body, over cap with the seeder of microphyte seed, the top of described seeds chamber is that cylinder, bottom are and in arcuation, are condensed to the round mouth that diameter is less than upper cylinder diameter, the top of seeds chamber is provided with chamber lid, bottom is provided with screen cloth, by screen cloth retainer ring, screen cloth is fixed on to seeds chamber bottom and inside contracts round mouth place; Piston and piston push rod that described piston body is made up of rubber form, and piston is closely embedded in seeds chamber; Described over cap is arranged on the bottom of seeds chamber; The central authorities of described chamber lid are provided with the push-rod hole that piston push rod passes; Described over cap, chamber lid, screen cloth retainer ring are cassette or spiral connection with seeds chamber.

The cylindrical diameter of described seeds chamber is 2-8cm; The diameter of described screen cloth is 1.5-7cm, is distributed with numerous round sieve apertures on screen cloth, and aperture is 0.1-0.5mm, and pitch of holes is 0.3-0.8 mm.

When use, first all parts of seeder is disassembled, high pressure moist heat sterilization, then installs screen cloth, over cap, and pretreated dry or wet seed is packed into after seeds chamber, piston body is packed into seeds chamber, dress upper chamber cover.When sowing, open over cap, two hands are held respectively seeds chamber and piston push rod, press down piston push rod after screen cloth is aimed to the container that will sow, and seed is just extruded from screen cloth equably, completes seeding operation.

The beneficial effects of the utility model

The seeder of microphyte seed for experiment of the present utility model, its seeds chamber inside is cylinder or arc structure, has prevented that dead angle structure is easy to the appearance of pollution problem; The seeds chamber of seeder and the opening surface of screen cloth are large, can increase work efficiency, and facilitate the operation such as charging and cleaning.The suitable microphyte seed of planting on medium on a large scale of seeder of the present utility model, can reduce manpower, saves the operating time and increase medium and effectively utilize area.In addition, seeder of the present utility model can be according to the seed size of minute seeds and seeding accuracy requirement, what the aperture on every screen cloth was processed is meticulousr, and the different screen cloth of the supporting multiple apertures of each seeder specification, and then improve the availability of the utility model seeder and the requirement of adaptation plant seed different size.

Embodiment

Below in conjunction with accompanying drawing, work of the present utility model ground is further set forth.

As shown in Figure 1 and Figure 2, experiment of the present utility model comprises seeds chamber 1, piston body 2, over cap 3, chamber lid 4, screen cloth 5, screen cloth retainer ring 6, piston 7, piston push rod 8 with the seeder of microphyte seed.The top of seeds chamber 1 is that cylinder, bottom are in arcuation and are condensed to the round mouth that diameter is less than upper cylinder diameter, and the cylinder diameter of seeds chamber is 2-8cm.Chamber lid 4 is connected with the top of seeds chamber 1 with cassette or sped structure.Screen cloth retainer ring 6 inside contracts round mouth with cassette or sped structure with the bottom of seeds chamber 1 and is fixedly connected with, screen cloth 5 is movably fixed to seeds chamber 1 and inside contracts the bottom of round mouth, the diameter of screen cloth is 1.5-7cm, on screen cloth, be distributed with numerous round sieve apertures 9, aperture is 0.1-0.5mm, and pitch of holes is 0.3-0.8 mm.Piston 7 and piston push rod 8 that piston body 2 is made up of rubber form, and piston 7 is closely embedded in seeds chamber 1, and the central authorities of chamber lid 4 are provided with the push-rod hole that piston push rod 8 passes.Over cap 3 is connected with the cylindrical bottom of seeds chamber 1 with cassette or sped structure.
