Detailed Description

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.

Example 1

Referring to fig. 1 and 2, the device for controlling the growth height and direction of cucumber vines in greenhouses comprises a cross bar 2, a worm wheel 6, a worm 7 and a driving motor 8, wherein the driving motor 8 can drive the worm 7 to rotate, the cross bar 2 is in meshing connection with the worm 7 in the vertical direction through the worm wheel 6 arranged at the end part of the cross bar 2, and the worm 7 is provided with a structure which is convenient for realizing meshing connection at a position corresponding to the worm wheel 6.

The worm 7 passes through the bearing 12 and is fixed on one side wall of the greenhouse along the length direction through the fixed connecting piece 1, and the cross rod 2 passes through the bearing 12 and is fixed on the greenhouse top support through the fixed connecting piece 1. The bearing adopts ball bearing, utilizes ball bearing can realize the relative rotation of horizontal pole easily.

The position, corresponding to the actual planting distance of the cucumber vines, of the cross bar 2 is provided with a string trolley 3 fixed on the cross bar, the nylon rope 4 is wound on the string trolley 3 according to the length required by the cucumber vines 11 in one growing season, and penetrates through the limiting cylinder 5 to droop to the position where the cucumber vines 11 are tied; the line car 3 is further provided with a lifting hook 9 and a limiting cylinder 5, and the limiting cylinder 5 is connected with the lifting hook 9 hung on the line car 3 through a wire rope 10. Before the height of the melon vine is lower than the cross bar 2 by a certain size, the height position of the limiting cylinder 5 is timely adjusted by pulling the rope 10 and the spring 13, once the growth height reaches the requirement, the position of the limiting cylinder 5 is fixed until the growth season is finished.

The limiting cylinder is made of transparent plastic, so that the growth direction of the melon vines can be limited and induced, and illumination is not affected.
