Abstract
The utility model relates to a homothermal seed germinator, which is composed of a heat insulating container, a heat radiating barrel, an electric heating wire, a semiconductor temperature sensor, a control circuit board, a control box, a germinator housing, a heat insulating cover and a germinator cover. The utility model has the advantages of low power consumption, convenient use, quick germination, high seed germination percentage, etc. The temperature constancy error is less than 0.1 DEG C. The seed germinator can be extensively used as the seed germinating tool of the crop, and is especially suitable for germinating the seeds of the vegetables.
Description
The utility model belongs to plant husbandry seed treatment instrument or electronic thermostatic utensil
Seed being carried out vernalization handle, is the technology that plant husbandry is extensively adopted.Presprouting of seeds instrument commonly used now has incubator, climatic chamber, generally form by cool-bag, heating wire, temperature measuring equipment, incubator shell and insulation case lid, temperature measuring equipment is generally mercury contact thermometer, and heating wire generally is placed on the cool-bag bottom.These vernalization instruments have big volume, and germination time is short, but power consumption many (400-3000W), the heat conduction is even inadequately, temperature stability poor (± 1 ℃), cost height, only be suitable for the crop seeds vernalization of making establishing in large scale, only limit to agri-scientific research unit and farm seed stations and use.As the numerous self-employed farmers of Chinese countryside, particularly vegetable grower's breeding is still adopted greenhouse, plastics hotbed to carry out presprouting of seeds, even is utilized body temperature vernalization.These method investments are less, but lost time is many, and germination time is long, and the difficult grasp of temp. and humidity, and percentage of seedgermination is low.
It is good that the purpose of this utility model is to design a kind of temperature stability, and power consumption is little, easy and simple to handle, and germination time is short, and the percentage of seedgermination height is fit to the constant temperature device for accelerating germination of seed that wide farmers, particularly vegetable grower are used.
The utility model is made up of cool-bag 1, thermal radiation tube 2, heating wire 3, semiconductor temperature sensor 4, control circuit board 5, control box 6, germinator shell 7, insulation cover 8 and germinator lid 9.Heating wire 3 is wrapped in around the thermal radiation tube 2, and is placed on together in the cool-bag 1, and thermal radiation tube 2 plays the uniformly transfer heat effect; Semiconductor temperature sensor 4 is placed between heating wire 3 and the thermal radiation tube 4; Heating wire 3, semiconductor temperature sensor 4, control box 6 link to each other with control circuit board 5 respectively; Be placed with insulation material 17 under cool-bag 1 bottom, thermal radiation tube 2, in thermal radiation tube 2, also have for the dividing plate 18 of placing seed, dividing plate 18 can be provided with 1 as required to a plurality of; Control box 6 sets adjusting turn-knob 14, power switch 15 and power line by transformer 10, temperature indicator 11, power supply indicator 12, thermostatical pilot lamp 13, temperature and plug 16 is formed; Control circuit board 5 by sensing circuit 19, difference is put and temperature measurement circuit 20, temperature-adjusting circuit 21, modulation generator 22, pulsewidth modulation 23, temperature adjustment output 24, power converting circuit 25 and mu balanced circuit 26 are formed, its annexation is shown in control circuit board 5 circuit block diagrams.
Cool-bag 1 adopts Dewar bottle or adds the material (as asbestos, polyurethane foam plastic) that can play insulation effect with metal, sheet plastic material and makes; The material of thermal radiation tube 2 usefulness copper coins or other energy uniformly transfer heat is made.As required, the constant temperature device for accelerating germination of seed can be made not isometric product, and that external form can be designed to is barrel-shaped, box-shaped or other shape that is suitable for.

Accompanying drawing 2 is a constant temperature device for accelerating germination of seed cutaway view
Accompanying drawing 3 is control circuit board 5 circuit block diagrams
The constant temperature device for accelerating germination of seed that is applicable to vegetable seeds vernalization is designed to barrel-shaped, volume is φ 9.5cm * 15cm, cool-bag 1 adopts Dewar bottle, thermal radiation tube 2 usefulness copper coins are made, and there is one deck dividing plate 18 centre, and power consumption is less than 5 watts, germinating cabinet's temperature can be set (must be higher than temperature) arbitrarily between 0-40 degree Celsius, the temperature constant error is less than 0.1 degree Celsius, and presprouting of seeds is quick, the germination rate height.As with cucumber, sour jujube green pepper, sponge gourd seed earlier with the emerge in worm water about 25 degree Celsius 2 hours, be placed on then in this constant temperature device for accelerating germination of seed, connect power supply, set up germination temperature, only need can germinate by 24 hours seeds, germination rate can reach 99%; Seeds such as wax gourd, watermelon, tomato also only needed to germinate in 36 hours.
The utility model can be widely used as the instrument that self-employed farmer, the institute of agricultural sciences, seed stations carry out presprouting of seeds. Be particularly suitable for the vegetable grower vegetable seeds is carried out vernalization, can in time arrange vegetables to produce according to the market demand, improve the unsettled situation of vegetable supply. The utility model can also be by fields such as medicine, health as the electronic thermostatic utensil.
