Abstract
The utility model relates to an electric heating plate for soil in a greenhouse and a temperature boosting and controlling device for soil using the electric heating plate, wherein, the electric heating plate consists of an electric heating element, a water-resistant and high-temperature-resistant polyester membrane for packaging the electric heating element, a sealing and waterproof glue rod or resin glue of a power extraction wire port of the electric heating element, and two heat dissipating metal plates covering the polyester membrane. The temperature self-control device consists of an AC contactor, a temperature controlling switch and an electric heating plate. The using way on the utility model is as follows: the electric heating plate is buried straightly in the soil; the probe of the temperature control switch is buried between the seedlings; an electrical control box provided with a contactor, and a temperature controller is arranged at an easy-to-operate position; and after the power supply is connected, the utility model immediately is in the use status. The utility model has the positive effects of automatic heating and temperature control, uniform heat distribution, high heat efficiency, good waterproof performance, long service life, good crop growing, and reduction of seedling cost from both aspects of get-warm equipment input and the improvement of crop quality.
Description
Technical field
The utility model belongs to agricultural technology field, the electricity heating and the temperature control equipment of the soil that is specifically related to nurse young plants in hothouses.
Background technology
In the past, in colder area, green house of vegetables reach in the winter time all to use in late autumn and early spring stove, wall with flues, facilities such as a heatable brick bed make and keep corresponding temperature in the canopy.Above heating mode, difficult control of temperature, big energy-consuming, vegetable grower's labour intensity are big, are unfavorable for plant growth, the production cost height.
Summary of the invention
The purpose of this utility model at first provides a kind of plastic shed soil electric hot plate and utilizes soil intensification, the temperature regulating device of electric hot plate, overcome existing booth with stove, wall with flues, facility intensification temperature control facilities such as a heatable brick bed have the energy consumption height, labour intensity is big, be unfavorable for plant growth, the deficiency that production cost is high.
Electric hot plate in the utility model encapsulates water-fast, the high voltage bearing polyester film of electric heating element by electric heating element, the water-tight glue rod or the resin glue of electric heating element power outlet mouth, and the two sides heat-dissipating metal sheet that coats polyester film is formed.Wherein electric heating element can be selected in the ribbon heater at the heating wire of existing high electricity-thermal conversion efficiency.What the utility model was selected for use is by conductive carbon black, Nano graphite powder, and paraffin, latex rubber mixes the electric heating bar that is cut into behind the sheet that is pressed into as the liquid coumarone of dispersant.
Soil intensification control temperature regulating device in the utility model is made up of A.C. contactor, temperature detect switch (TDS), electric hot plate.The electric hot plate power line connects the A.C. contactor output, A.C. contactor control switch jointing temp control switch, A.C. contactor input termination AC power.Temp control switch probe is embedded in the soil, and with lead with contacted the control switch and be connected.
Occupation mode of the present utility model is: electric heating vertically is embedded in the ranks or in the soil of furrow of crop, select the probe of corresponding temp control switch to be embedded between seedling, the electric cabinet that contactor and temperature controller are installed is placed position easy to operate, energized, the utility model promptly enter user mode.
Good effect of the present utility model is, heating, temperature control automatically, and uniform heat distribution, temperature can be selected.Behind the design temperature, keep constant temperature.Heat efficiency height, little power consumption.Water resistance is good, long service life, and crop growing state is good, reduces seedling cost from heating system input and two aspects of raising crop quality.
Description of drawings
Fig. 1 is the electrothermal plate structure schematic diagram.
Fig. 2 is the control temperature regulating device structure chart that heats up.
Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
1, manufactures the ribbon heater
