Edible mushroom greenhouse warming device

Abstract

The invention relates to an edible mushroom greenhouse warming device comprising a vehicle frame, a water tank, safety valves, an exhaust valve, a ground heating pipe, a contactor, a dry-wet probe, a heating rod, a low speed motor, a power distribution cabinet, a micro computer controller and a temperature probe. The water tank, the low speed motor and the power distribution cabinet are arranged on the vehicle frame, and the bottom of the vehicle frame is provided with rollers; a ball float valve, the dry-wet probe and the heating rod are arranged in the water tank; a water level gauge, the safety valve and the exhaust valve are arranged outside the water tank; the dry-wet probe is connected in parallel with the heating rod; the heating rod is connected with the power distribution cabinet; the low speed motor is connected with the power distribution cabinet; the water tank is connected with a water inlet pipe; the water tank is communicated with the ground heating pipe and forms a circulating water path; and a water inlet end of the ground heating pipe is provided with a water inlet valve, and the tail end of the ground heating pipe is provided with a non return valve. According to the invention, by means of the micro computer controller, the safety valve, the ball float valve, the water level gauge, the dry-wet probe and the low speed motor, automatic operation and safe operation of the device are achieved, temperature in the greenhouse is always within a temperature scope suitable for the growth of edible mushrooms, problems that in winter severe cold and continuous cloudy weather, the temperature in the edible mushroom greenhouse is too low, and fungus sacks and mycelia grow slowly, mushrooms bud slowly, and the yield is not high are solved, and the problem that edible mushrooms and vegetables are subjected to low-temperature freezing injury easily is solved.

Description

Technical field [0001] The invention relates to the field of agricultural equipment, in particular to an edible mushroom greenhouse warmer. Background technique [0002] In the severe winter season in the north, especially in the case of continuous cloudy weather, the outside air temperature will drop below -40℃. Because the edible mushroom greenhouse cannot get external heat, the temperature continues to drop. When the temperature inside the greenhouse is severe, it will be- Below 10°C, or even lower, it affects the growth of edible fungus mycelium, causing difficulty in fruiting, and a decline in yield, which seriously affects the income of mushroom farmers. [0003] The existing technical means are as follows: [0004] 1. In severe cold weather, cover the greenhouse with straw curtains, and then cover the straw curtains with shed film to increase the temperature in the shed. [0005] 2. Add a stove in the shed to extend the iron chimney and increase the temperature in the shed. [...

AI Technical Summary

Problems solved by technology

[0009] Covering the shed with straw curtains and shed film can increase the temperature in the shed by 1-2°C, but the effect of increasing temperature is not obvious; adding a stove and open fire in the middle of the night in the shed can increase the temperature by 1-2°C due to the large space. The effect is not obvious. At the same time, during the burning of lump coal and wood, harmful gases such as carbon monoxide and sulfur dioxide are likely to be produced, which is extremely unfavorable to the growth of edible fungus mycelia and fruiting bodies; Can play a buffer cooling purpose, the heating effect is not obvious
