Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse planting, in particular to a ventilation device for a cherry tomato planting greenhouse. Background Art

[0002] Cherry tomatoes are highly nutritious vegetables that can be eaten raw or cooked, but are more suitable for eating raw. Cherry tomatoes are often grown in vegetable greenhouses so that people can eat out-of-season vegetables.

[0003] After searching, application number 202121395023.9 disclosed a ventilation device for a vegetable growing greenhouse, including a greenhouse bow frame, a supporting limit rod and sealed glass. Sealed glass is installed on the top and both side ends of the greenhouse bow frame. Ventilation holes are provided on both side ends of the sealed glass located at the top of the greenhouse bow frame. The ventilation holes are sealed by ventilation glass, and the ventilation glass moves in the greenhouse bow frame through a quick opening and closing traction mechanism.

[0004] During use, a ventilation device for a vegetable-growing greenhouse in this patent application drives a rotating seat to rotate by using a driving motor on a quick opening and closing traction mechanism, so that the rotating seat drives the ventilation glass to rotate and move through the mounting plate and the supporting connecting rod to open the ventilation opening, thereby achieving the ventilation effect of the device. However, during such use, the ventilation glass is symmetrically arranged and arranged in multiple places. It is difficult to drive the two symmetrically arranged ventilation glass to move in the opposite direction through the quick opening and closing traction mechanism, so that the device needs to be equipped with a quick opening and closing traction mechanism for each ventilation glass, which increases the use cost of the device. In addition, the quick opening and closing traction mechanism also occupies more space in the greenhouse, is cumbersome, and reduces the practicality of the device. For this reason, we propose a ventilation device for a cherry tomato-growing greenhouse. Utility Model Content

A traction rotating rod is provided on the traction rotating rod, and a lifting mechanism is provided on the traction rotating rod to drive the sealed glass window to move up and down. The lifting mechanism includes a rope winding roller fixedly mounted on the outer wall of the traction rotating rod and a traction rope arranged on the rope winding roller. The end of the traction rope away from the rope winding roller passes through the wire through hole and is fixedly connected to the corresponding position of the top wall of the sealed glass window.

[0016] Furthermore, the output end of the regulating motor is fixedly mounted to the right end of the regulating worm.

[0017] The utility model provides a ventilation device for a cherry tomato planting greenhouse. It has the following beneficial effects:

[0018] 1. A ventilation device for a cherry tomato planting greenhouse is provided with a lifting mechanism and an adjusting mechanism. In the initial state, the sealed glass window is located at the top of the installation frame to form a sealing effect on the ventilation vents. When the interior of the greenhouse bow frame body needs to be ventilated, the output end of the control adjustment motor drives the adjusting worm to rotate, forcing the adjusting worm gear engaged with the adjusting worm to drive the rope winding roller on the traction rotating rod to rotate, and the traction rope is released. The installation frame moves downward along the inner cavity of the installation frame under the action of its own gravity, and the position of the ventilation vents is staggered, thereby releasing the sealing effect on the ventilation vents. The result is that the ventilation operation of the equipment can be realized. During this process, the limit slider forms a limiting guiding effect on the closed glass window by slidingly connecting with the internal limiting slide groove, so that the closed glass window can move up and down smoothly along the inside of the installation frame. The above operation is simple and practical, and the structure is reasonable and compact, which realizes the convenient ventilation operation of the equipment. The equipment only realizes the height adjustment operation of multiple closed glass windows by pulling the rotating rod, which reduces the use cost of the equipment, and also reduces the space occupied by the equipment inside the greenhouse bow frame body, thereby improving the practicality of the equipment.

[0019] 2. The ventilation device for a cherry tomato greenhouse is provided with protective rubber pads. A buffer is formed between the upper and lower walls of the inner cavity of the installation frame and the sealed glass window through the protective rubber pads to avoid direct collision and damage to the sealed glass window with the inner cavity wall of the installation frame when the height is adjusted. The sealed glass window has a normal plane structure rather than an arc-shaped special-shaped structure, which means that the process is simple, the cost is low and it is easy to obtain, which reduces the cost of using the equipment and is also convenient for later replacement and maintenance of the sealed glass window.

[0020] 3. This ventilation device for a cherry tomato greenhouse is equipped with a limiting fixed pulley, and the inside of the wire through hole is in rolling contact with the traction rope through the limiting fixed pulley, so as to reduce the friction between the traction rope and the inner wall of the wire through hole, reduce the loss of the traction rope, and extend the service life of the equipment.
