Problems solved by technology

However, the technology currently used is that the two ends of the rope are directly wound on the output shaft. Due to the thickness of the rope itself, when the rope is wound at one end and relaxed at the other end, the linear speed of the two ends of the rope is different, and the tension of the rope itself is uneven. , resulting in an unbalanced opening and closing of the vent

Abstract

The invention relates to a unidirectional transmission device for a ventilation opening of a greenhouse. The unidirectional transmission device comprises a power device, a drive shaft, a first ratchet wheel, a second ratchet wheel, a first ratchet, a second ratchet, a first driven wheel and a second driven wheel, wherein the first and second driven wheels are rotatably arranged on the drive shaft, the first and second ratchet wheels and the first and second driven wheels are arranged on the drive shaft according to the order sequentially as follows: the first driven wheel, the first ratchet wheel, the second ratchet wheel and the second driven wheel, the first ratchet is arranged on the circumference of the first driven wheel, the second ratchet is arranged on the circumference of the second driven wheel, the first and second ratchet wheels are fixedly connected with the drive shaft, and ratchet teeth are matched with the first and second ratchets, so that either the first driven wheel or the second driven wheel rotates along with the drive shaft when the drive shaft rotates forwardly or reversely. According to the unidirectional transmission device for the ventilation opening of the greenhouse, the unidirectional transmission of two directions can be achieved by adopting one power device and one transmission device, the structure is compact, and the transmission efficiency is high.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a one-way transmission device used for air vents in greenhouses. Background technique [0002] The transmission device is an intermediate device that transmits the power of the power device to the working mechanism. It is the most important part of the mechanical equipment. The known gear mechanism transmits power through the meshing of the gears. Compared with other transmission mechanisms, its structure is compact and Reliable work and high transmission efficiency. The existing widely used progressive gears, circular arc and parabolic profile gears can realize two-way transmission, but in some occasions where power is transmitted in one direction, a one-way transmission mechanism must be used to achieve the purpose. The one-way transmission in the prior art The mechanism generally adopts a ratchet and pawl structure, but a set of ratchet and pawl structures can only real...
