Household eupolyphaga cultivation hotbed

Abstract

The invention discloses a household eupolyphaga cultivation hotbed, which comprises a plastic basin and a wood basin, wherein the plastic basin is provided with a smooth inner wall, the diameter of the plastic basin is 80 cm, the diameter of the wood basin is 2 cm greater than that of the plastic basin, the wood basin is one third lower than the plastic basin, a whole body is defined by the plastic basin and the wood basin, and a heater strip and a thermal insulation material are arranged between the plastic basin and the wood basin. The household eupolyphaga cultivation hotbed is characterized by further comprising a low-voltage working power supply and a temperature controller, wherein the low-voltage working power supply is formed by a step-down transformer, a rectifier, a filter, a voltage stabilizer and a power indicator which are electrically connected in sequence, and the temperature controller is formed by a sensor, a regulator 1, an amplifier, a digital-to-analog converter, a relay, a regulator 2, a trigger, a thyristor, a heater and a heating indicator which are electrically connected in sequence; the low-voltage working power supply is further electrically connected to the temperature controller for supplying the power to the temperature controller, when the temperature of nutrient soil in the plastic basin is lower than 28 DEG C, the thyristor works and the heater is electrified, and when the temperature of the nutrient soil in the plastic basin is higher than 30 DEG C, the thyristor stops working and the heater is diselectrified, so that the temperature of the nutrient soil in the plastic basin is kept within 28-30 DEG C, and the nutrient soil becomes the hotbed for eupolyphaga. The household eupolyphaga cultivation hotbed has the advantages of simple circuit setting, job safety and stable performance, the heater works at the low-voltage state of 45 V, and the household eupolyphaga cultivation hotbed is suitable for rural families in vast rural areas to cultivate the eupolyphaga so as to promote farmers to build up the family fortunes.
