Efficient coarse salt snow melting and removing device for top of greenhouse

Abstract

The invention relates to the field of greenhouse snow removing, and discloses an efficient coarse salt snow melting and removing device for the top of a greenhouse. The equipment comprises supporting columns which are symmetrical left and right, and two telescopic rods which are symmetrical left and right are arranged between the supporting columns on the two sides. According to the efficient coarse salt snow melting and removing device for the top of the greenhouse, a coarse salt spreading device is arranged, salt spreading and snow melting are conducted before subsequent treatment, a subsequent device is provided with a turnover device, the part, with the high salt content, of the upper layer is turned over to the middle layer of accumulated snow, the snow melting effect is achieved, and the effect of increasing the snow melting rate to the maximum degree is achieved; meanwhile, an air injection device is arranged on the subsequent device to laterally spray out the half-melted accumulated snow, the situation that the accumulated snow is completely melted is not needed, and the situation that the accumulated snow with the high salt content is completely melted and flows down, and the land quality of the lower side of the greenhouse is affected is reduced; and the lower side of the whole equipment does not make contact with a protective film of the greenhouse, and the situation that the film is damaged is effectively avoided.

Description

technical field [0001] The invention relates to the field of snow removal in greenhouses, in particular to a high-efficiency crude salt snow-melting snow removal device on the top of a greenhouse. Background technique [0002] The development of greenhouse planting technology has changed the operating mode of the vegetable and fruit planting industry that is overly dependent on the weather. However, the use of greenhouse technology is still affected by the climate to a certain extent. This effect is especially common in northern regions. Excessive snow accumulation not only damages The structure of the greenhouse is damaged or even crushed, and the snow covered on the greenhouse seriously affects the light received by the crops, thereby affecting the growth of the crops. At present, the measures taken against the heavy snow weather in the greenhouse are mainly aimed at the structure of the greenhouse itself, and the snow removal method is also mainly Relying on manpower, thi...

[0002] The development of greenhouse planting technology has changed the way vegetables and fruits are overly dependent on the weather. However, the use of greenhouse technology is still affected by the climate to a certain extent. This effect is especially common in northern regions. Excessive snow accumulation not only damages The structure of the greenhouse is damaged or even crushed, and the snow covered on the greenhouse seriously affects the sunlight received by the crops, thereby affecting the growth of the crops. At present, the measures taken against the heavy snow weather in the greenhouse are mainly aimed at the structure of the greenhouse itself, and the snow removal method is also mainly Relying on manpower, this method of snow removal is not only inefficient, but also labor-intensive. At the same time, the existing scraping methods are difficult to deal with the top of the greenhouse. Usually, people go up to clean it or cover the snow with a protective film below. This method is extremely difficult. It is easy to cause damage to the top of the greenhouse and affect the subsequent growth of crops. At the same time, the existing salt-sprinkling snowmelt method is inefficient because the salt can only be sprinkled on the snow surface, and the salt flows directly along the shed wall after the snow melts. Affect the fertility of the land, and then affect the output of subsequent crops, etc., in view of the above shortcomings, the present invention has improved
