Curtain device is rolled up to serving formula that greenhouse was used

TL;DR: In this paper, a curtain device is rolled up to serving formula that greenhouse was used's circuit control mechanism is used for controlling actuating mechanism, and drive mechanism installs in the top of the back wall in greenhouse, and receipts paying out machine constructs and actuating mechanisms installs respectively in the bottom of back wall.
Abstract: The utility model relates to a greenhouse equipment technical field especially relates to a curtain device is rolled up to serving formula that greenhouse was used. The utility model discloses a curtain device is rolled up to serving formula that greenhouse was used's circuit control mechanism is used for controlling actuating mechanism, and drive mechanism installs in the top of the back wall in greenhouse, and receipts paying out machine constructs and actuating mechanism installs respectively in the bottom of back wall, and actuating mechanism is connected with receipts paying out machine structure, receives the paying out machine structure and connects drive mechanism and book curtain in order through a plurality of ropes to put the rope and drive to roll up the curtain and spread out downwards or roll -up in the top of back wall along canopy surface from the top of back wall through drawing, canopy surface's upper and lower both ends are equipped with the spacing disconnection pass of touching respectively. The aforesaid setting of this curtain device is rolled up to serving formula that greenhouse was used makes the range interval of rope orderly, can effectively avoid appearing winding confusion, superimposing thread and operation problems such as " interference " between the rope, and be convenient for operation and maintenance when strengthening operation safety, can realize actuating mechanism " a tractor serves several purposes ", by a wide margin reduction in production cost.

TL;DR: In this paper, a shutter winding device consisting of a threaded spindle, a walking sleeve and a force-unloading pulley block bracket is described, where the walking sleeve is matched with a thread of the threaded spindles and is capable of moving along the length direction of the thread following a rotation of the spindle.
Abstract: The invention relates to the field of a greenhouse and especially relates to a shutter winding device. The shutter winding device comprises a threaded spindle, a walking sleeve and a force-unloading pulley block bracket, wherein the walking sleeve is rotatably sleeved on the threaded spindle; the walking sleeve is matched with a thread of the threaded spindle and is capable of moving along the length direction of the threaded spindle following the rotation of the threaded spindle; the force-unloading pulley block bracket is fixedly arranged on the outer surface of the walking sleeve. When the threaded spindle clockwise rotates, a wire harness is penetrated through the force-unloading pulley block bracket; after the force is unloaded by the force-unloading pulley block bracket, the wire is wound on the threaded spindle; due to a constraining force of the wire harness, the stress endured by the force-unloading pulley block bracket on a winding position is balanced and the force-unloading pulley block bracket cannot be rotated following the threaded spindle; the force-unloading pulley block bracket is fixedly arranged on the outer surface of the walking sleeve and the walking sleeve is rotatably sleeved on the threaded spindle, so that the walking sleeve can realize displacement in the manner of matching with the thread of the threaded spindle.

TL;DR: In this article, an automatic curtain rolling device for agricultural greenhouses is presented, in which a gear motor drives a rotating shaft to rotate, and a curtain rolling shaft is stretched to move through a driving belt, so that the convenient paving and rolling of covering grass curtains can be realized.
Abstract: The invention discloses an automatic curtain rolling device for agricultural greenhouses, and relates to the technical field of agricultural equipment. Thus, the problems of the non-uniform paving oftwo ends during paving due to soft grass curtains when the grass curtains are paved on an agricultural greenhouse and the heat preservation of the agricultural greenhouse affected by large gaps can bemainly solved. The device mainly includes an agricultural greenhouse body; one side of the agricultural greenhouse body is provided with a limit mechanism, a rainproof mechanism, an indicating mechanism, a controller, an automatic curtain rolling mechanism and a gap covering mechanism. A gear motor drives a rotating shaft to rotate, and a curtain rolling shaft is stretched to move through a driving belt, so that the convenient paving and rolling of covering grass curtains can be realized; during the moving of the curtain rolling shaft, directional movement can be performed on the curtain rolling shaft through arc-shaped slide rails, so that the smoothing of the two sides of the covering grass curtains can be guaranteed; and supplementary grass curtains on a rotary shaft can be pulled to move and paved between the gaps of the covering grass curtains. The beneficial effects of the device are as follows: the paved grass curtains can be smoother; the paving can be more comprehensive; andbetter heat preservation effects can be achieved.
