Description

Greenhouse ventilation device Technical Field The utility model belongs to the technical field of ventilation devices, and particularly relates to a greenhouse ventilation device. Background Greenhouse, also known as greenhouse. Light-transmitting, heat-insulating (or heating) facility for cultivating plants. In seasons unsuitable for plant growth, the greenhouse can provide a growing period and increase yield, is mainly used for cultivating or raising seedlings of plants like warm-loving vegetables, flowers and trees in low-temperature seasons, has various types of greenhouses, and can be divided into various types according to different roof truss materials, lighting materials, appearance, heating conditions and the like, but in a broad sense, the greenhouse is one of the greenhouses, and the purpose of the greenhouse is to maintain a certain temperature, and is an essential link in the use and ventilation of the greenhouse. Based on the above, the inventor finds that the existing ventilation device is usually provided with a filter screen when in use, and in the actual operation process, the filter screen can effectively block solid particles, dust and other impurities in the greenhouse, so that the impurities are retained at the position of the filter screen, and the fan operation is prevented from being influenced, however, if the impurities are not cleaned for a long time, the impurity accumulation can seriously influence the ventilation effect, and the filter screen is cleaned in a disassembling mode, so that the operation is complicated, the fan operation is stopped, and the normal ventilation operation is directly disturbed. Accordingly, the present invention provides a ventilation device for greenhouse, which is improved with respect to the existing structure and the defects, so as to achieve the purpose of higher practical value. Disclosure of utility model In order to solve the technical problems, the utility model provides a ventilation device for a greenhouse, which aims to solve the problems that the existing mode of disassembling and cleaning a filter screen is complex in operation, a fan is required to be suspended, and normal ventilation operation is disturbed. The utility model discloses a ventilation device for a greenhouse, which is characterized by comprising the following specific technical means: The utility model provides a warmhouse booth ventilation unit, includes the big-arch shelter body, one side of big-arch shelter body is equipped with the ventilation window, the opposite side of big-arch shelter body is equipped with the casing, the inside block in top of casing is connected with filter screen one, a set of spout has been seted up to the lateral wall of one side of filter screen one, be equipped with reciprocal lead screw and slide bar in the spout, the cover is equipped with the slider on reciprocal lead screw and the slide bar, one side of slider is equipped with the scraper blade, the bottom of casing is equipped with the collection chamber, be equipped with the pull box in the collection chamber, the bottom of pull box is equipped with the air exhauster, one side of air exhauster is equipped with a plurality of air outlets, just one side of casing is equipped with the ventilation pipe, ventilation pipe and big-arch shelter body coupling. Further, a second filter screen is arranged at the bottom of the drawing box. Further, the reciprocating screw rod is connected with the sliding block through reciprocating threads.
