Embodiment Construction

[0019] Above, the accompanying drawings of the specification show a specific embodiment of the present invention. The left and right top windows of this wide and narrow multi-span greenhouse have the same angle opening device, including column 1, truss 2, drive motor, transmission track gear meshing rack, rack connected to push-pull rod, push-pull rod connected to strut, strut Hinged with greenhouse dormer. The same-angle spreading device includes a front spreading device 1 and a rear spreading device 2 installed in parallel on the truss. The front spreading device 1 is used for opening and closing the left roof window of the wide and narrow greenhouse, and the rear spreading device 2 is used for opening and closing the right roof window of the wide and narrow greenhouse. The front expansion device 1 is composed of the front expansion motor 3, the front reducer 4, the front transmission track gear 5, the front rack 6 meshed with it, and the front push-pull rod 7, the front st...

Abstract

The invention discloses a device for expanding left and right roof windows of wide and narrow multi-span greenhouses with the same angle, and relates to opening and closing of greenhouse roof windows. The device comprises columns, trusses, motors, gears, racks, push-pull rods, and supporting rods, and the supporting rods are hinged to the greenhouse roof windows. The device is characterized in that a front expanding apparatus and a rear expanding apparatus are parallelly installed on the trusses. The front and rear expanding apparatuses are respectively formed by motors, reducers, track gears, rack connection push-pull rods, stroke compensation mechanisms, left and right side roof windows and supporting rods. The front stroke compensation mechanism and the rear stroke compensation mechanism have the same structure which is a telescopic sleeve structure and formed by an outer sleeve, an inner cylinder, a spring and an inner supporting cylinder. The device has the beneficial effects that the stroke compensation mechanisms are connected to the push-pull rods, stroke difference between lateral movement of the push-pull rods of the narrow greenhouse and the wide greenhouse is compensated, and therefore the roof windows of the wide and narrow greenhouses can be expanded with the same angle. Motors and transmission devices thereof are saved, and investment is saved.

Description

Technical field: [0001] The invention relates to a greenhouse, mainly relates to a wide and narrow multi-span greenhouse, in particular to the opening and closing of the top window of the wide and narrow multi-span greenhouse. Background technique: [0002] Modern greenhouses need to open and close the top windows regularly to facilitate ventilation and adjust the room temperature. The openable tops are equipped with insect nets to prevent flying insects. In the prior art, for the multi-span wide greenhouses with the same width or the multi-span narrow greenhouses with the same width, the opening or closing of the roof windows of the sloping roof only requires the installation of a motor, a reducer, a transmission gear meshing rack, and a rack connection. It can be realized by connecting the push-pull rod and the push-pull rod to the brace rod of the opening and closing window. Similarly, if it is a multi-span greenhouse with horizontal width and narrowness connected, it i...
