[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A gas equalization device for greenhouse planting includes a wind duct 1. A blowing assembly 15 is installed inside the wind duct 1. The blowing assembly 15 consists of a motor, impeller, protective net, and other components. Its specific working principle is existing technology and will not be elaborated here. A connecting ring 2 is fixedly welded to the top of the wind duct 1, and a connecting rod 3 is fixedly inserted inside the connecting ring 2. A support block 4 is provided above the connecting ring 2, and a receiving groove 10 is formed on the inner wall of the support block 4. A gear 5 is connected to the center of the receiving groove 10 via a bearing. The top of the connecting rod 3 passes through the inner wall of the support block 4 and is fixedly connected to the bottom end of the gear 5. Support rods 12 are symmetrically connected to the sides of the support block 4, and the top of the support rods 12 is connected via a mounting plate 13. The mounting plate 13 can be installed on the mounting surface by bolts. The specific installation principle will not be elaborated here. Through the arrangement of the connecting ring 2, connecting rod 3, and support block 4, the manual swinging requirement of the wind duct 1 can be met, thereby increasing the air delivery range of the wind duct 1.

[0022] Furthermore, refer to Figure 2 and Figure 3 It can be seen that a hydraulic push rod 6 is fixedly installed on the inner wall of the receiving groove 10, and the end of the hydraulic push rod 6 is connected to the toothed plate 8 through the connecting plate 7. The side of the toothed plate 8 meshes with the side of the gear 5. The specific extension and retraction principle of the hydraulic push rod 6 is the existing technology. By starting the hydraulic push rod 6, the toothed plate 8 can be driven to move back and forth, thereby realizing the automatic swing of the gear 5, the connecting ring 2 and the air duct 1, which can effectively improve the air supply effect of the device.

[0023] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the toothed plate 8 has an insertion groove inside, and a connecting strip 9 is inserted into the inner wall of the insertion groove. The end of the connecting strip 9 is fixedly connected to the inner wall of the receiving groove 10. During use, the toothed plate 8 can move stably inside the receiving groove 10 by the cooperation of the connecting strip 9 and the insertion groove.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a support ring 11 is fixedly connected above the connecting ring 2, and an annular groove adapted to the support ring 11 is opened at the bottom of the support block 4. Through the cooperation of the support ring 11 and the annular groove, the connecting ring 2 and the bottom of the support block 4 can be slidably connected to achieve the suspension of the air duct 1 without affecting the normal swing of the air duct 1.

[0025] Furthermore, refer to Figure 4It can be seen that the top of the support block 4 is covered by a cover plate 14, and the corner of the cover plate 14 is provided with reserved holes. The inside of the reserved holes is connected to the support block 4 by bolts. The cover plate 14 can protect the parts stored in the receiving groove 10. The inner wall of the top of the support block 4 is provided with screw holes that are compatible with the bolts, which are not shown in the figure. Through the cooperation of the cover plate 14 and the bolts, it is easy for the staff to remove the cover plate 14 from the top of the support block 4 so that the staff can perform maintenance operations such as lubrication on the hydraulic push rod 6 and the toothed plate 8.

[0026] Furthermore, refer to Figure 3 It can be seen that the longitudinal section of the support ring 11 and the annular groove is set as a T-shaped structure. The top of the support ring 11 is evenly provided with slots, and the inside of each slot is equipped with ball bearings. Since the support ring 11 and the annular groove are set as T-shaped, the weight of the air duct 1 can be distributed. The slots and ball bearings are not shown in the figure. The connection method between the two is the prior art, which will not be described in detail here. Through the cooperation of the two, the smooth swing of the air duct 1 can be further guaranteed.

[0027] Working principle: When using this utility model, the operator can first align the mounting plates 13 distributed on the top of the air duct 1 with the mounting surface inside the greenhouse, and then insert each set of bolts into the interior of the mounting plates 13 to fix the mounting plates 13 and the mounting surface, thereby realizing the suspension installation of the air duct 1. Through the high-speed rotation of the motor and impeller inside the blowing assembly 15, air can be blown into the greenhouse to ensure the balance of the gas inside.

[0028] During the operation of the air duct 1, the hydraulic push rod 6 is activated, which drives the connecting plate 7 to slide back and forth inside the receiving groove 10. Since the connecting plate 7 is connected to the toothed plate 8 and the toothed plate 8 is meshed with the gear 5, the connecting rod 3, the connecting ring 2 and the air duct 1 can be driven to swing continuously, which can effectively improve the air supply range of the device. With the support ring 11 connected above the connecting ring 2 and the annular groove opened at the bottom of the support block 4, the stable rotation of the air duct 1 can be effectively guaranteed. The above is the complete working principle of this utility model.

[0029] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
