Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to an improved agricultural planting greenhouse. Background Technology

[0002] In the process of agricultural modernization, greenhouses, with their controllable environmental conditions, have become an important production platform for off-season crops and high-value-added fruits and vegetables.

[0003] Based on the above, the inventors have discovered the following problems: existing greenhouses still rely on manual pipe-pulling for irrigation. Since greenhouses are mostly long and narrow structures, when manually pulling pipes for irrigation, workers need to drag rubber water pipes back and forth inside the greenhouse. The water pipes are prone to getting tangled with plants or scratching the fruits, which in turn affects the crops.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an improved agricultural greenhouse, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide an improved agricultural greenhouse to solve the problem mentioned in the background art that existing greenhouses still rely on manual pipe-pulling irrigation in the watering process.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: An improved agricultural greenhouse includes a main body and a ventilation mechanism. The main body includes a greenhouse frame, with a greenhouse film covering the outside of the frame. Electric telescopic rods are fixedly installed on both sides of the top of the inner part of the frame. A support frame is fixedly installed at the bottom of a pair of electric telescopic rods. Movable seats are fixedly installed on both sides of the bottom of the support frame. A spray pipe is rotatably connected between each pair of movable seats. Several nozzles are installed at the bottom of each spray pipe, and a water inlet connector is installed on one side of the upper end of each spray pipe. The ventilation mechanism includes two sets of grilles, which are respectively inserted into both sides of the greenhouse film, and the opposite sides of the two sets of grilles are connected to both sides of the greenhouse frame.

[0007] Furthermore, a transmission box is fixedly installed on the bottom side of the support frame, one end of each pair of spray pipes extends through the transmission box into the interior, and each is fitted with a synchronous pulley, and the pair of synchronous pulleys are connected by a synchronous belt drive.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the synchronous pulley in the transmission box drives a pair of spray pipes to rotate synchronously through the synchronous belt, ensuring that the spray angle of the nozzles is consistent, improving the uniformity of irrigation, and protecting the transmission components from external interference.

[0009] Furthermore, a first drive motor is fixedly installed on one side of the transmission box, and the output end of the first drive motor is connected to one of the synchronous pulleys.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first drive motor provides power to the synchronous pulley, drives the sprinkler pipe to flexibly adjust the angle, adapts to the sprinkler needs of different crops, and improves the targeted irrigation and automation level.

[0011] Furthermore, the interior of the grille is rotatably connected with several fan blades, the inner wall of the grille is provided with a receiving cavity, one end of each of the fan blades extends into the interior of the receiving cavity, and each is fitted with a worm gear.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the fan blades rotate within the grille to adjust the ventilation volume, the housing protects the transmission components, avoids the influence of dust and moisture, and ensures the stable operation of the fan blades.

[0013] Furthermore, each of the accommodating cavities is rotatably connected to a rotating shaft, and a worm is fitted on one side of the worm wheel on each rotating shaft, with the worm meshing with the worm wheel.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the worm gear and worm wheel meshing transmission transmit the power of the rotating shaft to the fan blades. The worm gear and worm wheel transmission has self-locking properties, which can fix the fan blade angle and precisely control the ventilation size.

[0015] Furthermore, a second drive motor is fixedly installed on one side of the upper end of the grille, and the output end of the second drive motor is connected to the rotating shaft for transmission.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the second drive motor drives the rotating shaft to rotate the worm gear, realizes the automatic adjustment of the fan blades, quickly responds to the ventilation needs in the greenhouse, and is convenient and efficient to operate.

[0017] Furthermore, fans are fixedly installed on one side of one set of grids inside the greenhouse frame, and a door curtain is provided at one end of the greenhouse film.

[0018] The beneficial effects of adopting the above-mentioned further solutions are that the fan enhances the ventilation efficiency of the grille, accelerates the air circulation inside the greenhouse, and the door curtain facilitates personnel entry and exit, thereby improving the practicality and environmental control capabilities of the greenhouse.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: The improved agricultural greenhouse has a main frame that supports the greenhouse film to form a planting space. An electric telescopic rod drives the support frame to rise and fall, and the height of the sprinkler pipes can be adjusted to meet the spraying requirements of plants of different growth heights. The sprinkler pipes spray the crops through the nozzles, and under the drive of the first drive motor, a pair of sprinkler pipes can swing back and forth to spray, increasing the spraying area while avoiding direct spraying of the plants by the nozzles, thus preventing damage. The ventilation mechanism's grille allows air circulation inside and outside the greenhouse, taking into account both irrigation and ventilation functions, providing a suitable growing environment for crops. The fan enhances the ventilation efficiency of the grille and accelerates air circulation inside the greenhouse. The door curtain facilitates personnel entry and exit, improving the practicality and environmental control capabilities of the greenhouse. Attached Figure Description

[0026] Specifically, the working principle of this improved agricultural greenhouse is as follows: During use, the electric telescopic rod 105 drives the support frame 106 to rise and fall to adjust the height of the sprinkler pipes 108.

During ventilation, the second drive motor 203 drives the rotating shaft 205, which drives the fan blades 202 in the grid 201 to rotate through the worm gear 207 and worm wheel 206 to adjust the ventilation volume. The fan 104 enhances air circulation, and the door curtain 102 facilitates personnel entry and exit.
