Greenhouse main ridge translation ventilation device

Abstract

The present invention provides a greenhouse main ridge translation ventilation device. Lower portions of front columns and rear columns are welded to a greenhouse frame. Upper ends of the corresponding front columns and rear columns are connected via suspender tracks. A suspender roller of a suspender is installed on each suspender track. Two ends of leading screws are installed at inner sides ofthe front columns and the rear columns via bearings. Sprocket wheels are installed on the leading screws. The sprocket wheels are connected with a sprocket wheel of a motor via a chain. Middle nuts ofthe suspenders are installed on the leading screws. Lower connecting ends of the suspenders are connected with lined quilt frames. End portions of a heat preservation quilt are installed in the linedquilt frames. The greenhouse main ridge translation ventilation device has the advantages that when the motor is started, the greenhouse can be rapidly ventilated; switching is smooth and convenient,the greenhouse ventilation problem which is the headaches for farmers is solved, generation of infectious diseases is avoided, and the cultivation risk is decreased to the minimum; and greenhouse temperature is ensured without causing heat loss.

Description

technical field [0001] The invention relates to a greenhouse positive ridge translation ventilation device. Background technique [0002] At present, in the shed-style farming, in winter, by opening the greenhouse during the day, the heat preservation quilt is allowed to shine into the shed to store heat, and at night and cloudy days, it is kept warm by covering the heat preservation quilt; while in summer, the heat preservation quilt is not blocked by covering the greenhouse Sunlight, lowering the temperature, and a large number of cultured animals excrete and breathe in the shed, resulting in high temperature in the shed, high temperature, and volatilization of excrement, resulting in cloudy air in the shed and high ammonia concentration. These factors lead to the loss of cultured animals. Various diseases are not conducive to the growth of cultured animals, and cause a large number of deaths in severe cases. Therefore, it is required that the air flow in the shed should b...

[0002] At present, in the shed-style farming, in winter, by opening the greenhouse during the day, the heat preservation quilt is allowed to shine into the shed to store heat, and at night and cloudy days, it is kept warm by covering the heat preservation quilt; while in summer, the heat preservation quilt is not blocked by covering the greenhouse Sunlight, lowering the temperature, and a large number of cultured animals excrete and breathe in the shed, resulting in high temperature in the shed, high temperature, and volatilization of excrement, resulting in cloudy air in the shed and high ammonia concentration. These factors lead to the loss of cultured animals. Various diseases are not conducive to the growth of cultured animals, and cause a large number of deaths in severe cases. Therefore, it is required that the air flow in the shed should be good, and the insulation performance should also be good

At present, the ventilation of the shed, the first method is to use a ventilation fan to draw air from the side, and the ammonia gas and hot steam in the shed are mainly concentrated in the upper part of the shed. Lose a lot of heat in the shed; the second method is to open a small opening on the top of the shed to let the ammonia and hot steam discharge naturally. Due to the small opening area, the ammonia gas cannot be discharged in time, which will easily lead to the accumulation of ammonia concentration in the shed. If it is too high, there will be problems. In addition, the regular opening will cause a large loss of heat in the shed, which is not conducive to heat storage

The third method is that the insulation of the greenhouse is not completely covered, and a wind is left on the top to bring ventilation. In this way, there is no problem with ventilation in spring, summer, and autumn, but in winter, it is necessary to add additional coverings to this wind belt. , for users, they have to go to the roof of the shed every day to open the cover to ventilate, and then cover it after ventilation. The workload is heavy and the risk increases. At the same time, the second cover and the original greenhouse cannot be completely sealed, resulting in heat loss.
