Temperature-adjustable planting greenhouse

Technical Field

The utility model relates to a planting greenhouse, concretely relates to farming uses and ventilation unit conveniently opens or closed greenhouse device.

Background

Greenhouse cultivation refers to a cultivation method of horticultural crops. The warm-keeping, light-transmitting and heating device structure (such as cold bed, warm bed, greenhouse, etc.) and corresponding technical measures are used to protect warm-living plants from cold and overwintering or promote growth, blossom and fruit bearing in advance, etc. In China, two types of greenhouses for potted flower production are mainly sunlight type greenhouses and modern greenhouses. The sunlight type greenhouse is widely applied in China, particularly in the north with sufficient light energy, has only one south-facing light inlet surface in a common single roof form, is simple in structure, can receive more sunlight in winter, is covered by the sunlight at night, is good in heat insulation performance, is low in construction cost, and has good practical value.

In order to adjust the temperature or humidity of the air environment in the greenhouse, some ventilation devices are generally required to be installed, and the existing method is to install some exhaust fans, and the installation of the exhaust fans has two problems, namely, the first problem is that the exhaust fans are high in cost and easy to damage, and the other problem is that the exhaust fans cannot be well sealed, namely, under any condition, the fan device is always in an open state, so that the situation that the fan device is completely sealed under the severe weather environment is difficult to achieve. In summary, it is difficult for existing fan assemblies to isolate the exterior and interior of a greenhouse from each other.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a low cost, the structure is simpler and very conveniently opens or is closed to the vent to greenhouse device that the ambient temperature to the greenhouse adjusted.

In order to accomplish the above object, the utility model provides an adjustable planting greenhouse of temperature, it includes greenhouse main part, well cavity bucket, dead lever and lift piece, the greenhouse main part has the greenhouse roof, a plurality of ventilation unit are installed to the roof, ventilation unit specifically includes:

the greenhouse comprises a greenhouse body, a hollow barrel and a heating device, wherein the greenhouse body is provided with a through structure, an upper opening of the hollow barrel is arranged on the outer side of the greenhouse body, a lower opening of the hollow barrel is arranged on the inner side of the greenhouse body, and a side wall of the hollow barrel is provided with a first through hole and a second through hole;

the two ends of the fixed rod are respectively fixed on the inner wall surface of the hollow barrel, and the middle part of the fixed rod is provided with a third through hole;

the lifting piece is provided with a covering disc and a lifting rod from top to bottom, the lifting rod penetrates through the third through hole, the lower end of the lifting rod is provided with a fourth through hole, and the diameter of the covering disc is larger than the caliber of the upper opening of the hollow barrel;

the pulling rope is provided with an annular rope part and a vertical section part, the vertical section part is arranged at the bottom of the annular rope part, and the annular rope part penetrates through the first through hole, the fourth through hole and the second through hole.

The beneficial effect that above-mentioned scheme produced does: the cover plate can be controlled to be opened by the up-and-down movement of the pull rope, so that the opening and closing of the upper opening of the hollow barrel are controlled by the cover plate, and the adjustment of the temperature or the ventilation in the greenhouse is easily completed. And the structure is very simple and low in cost, and the hollow barrel can be closed when needed. In particular, in a natural state, i.e. when the annular rope portion does not exert a force on the lifter, the cover plate automatically closes the upper opening of the hollow tub due to gravity. And when carrying out the lapse to the pulling rope, then can correspondingly drive annular rope portion and take up, especially make the taut expansion of the inside annular rope portion of cavity bucket, drive the lifter and upwards remove gradually from this to make the cover dish rebound and separate with the upper portion opening of cavity bucket, just so realized closing and opening to the upper portion opening of cavity bucket. It should be noted that the bottom of the vertical section needs to be fixed in a fixed position, for example, by being wound around a column or by other known fixing means.

A preferable scheme is that the device further comprises a driving lifting assembly, which specifically comprises a fixed plate, a vertical plate, a motor, a driving gear, a supporting gear, a chain and a connecting plate, wherein the vertical plate is arranged on the fixed plate, one side of the vertical plate is provided with the rotatable driving gear and the supporting gear, the chain is sleeved on the driving gear and the supporting gear, the connecting plate is fixed on the chain, and the motor is connected with the driving gear;

the vertical section part is fixedly connected to the connecting plate.

The beneficial effect that above-mentioned scheme produced does: in order to save manual physical power and more accurately control the pulling rope, a motor driving device is arranged, when the chain drives the connecting plate to be at a relatively high position, the vertical section part is in a loose state, and the upper opening is sealed by the covering disc. And when the connecting plate is driven to move to a relatively low position through the chain, the annular rope part is in a tensioning state at the moment, so that the lifting rod is driven to move. Therefore, the connecting plate can be switched between a relatively low position and a relatively high position through forward rotation or reverse rotation of the motor, and the two positions are switched to ensure that the covering disc just completes opening and closing of the upper opening.

Preferably, the cover plate has a circular flat plate portion and an inclined extension portion, and the circular flat plate portion is fixed to the top of the lifting rod by a fixing screw.
