Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf drying technology, and in particular to a ventilation structure for a drying shed for yellowing tobacco. Background Technology

[0002] Sun-dried tobacco is usually grown in a tobacco drying shed. The drying process is generally divided into three stages: withering and yellowing, color fixing, and drying. At different stages, the temperature and humidity of the tobacco leaves need to be adjusted to different degrees to ensure both the appearance and internal quality of the tobacco while minimizing the drying time and saving on drying costs.

[0003] Currently, most existing drying sheds for drying yellow tobacco are sealed by covering the top of the mounting frame with a thin film for protection. During ventilation, operators need to roll up both ends of the film, which is cumbersome, time-consuming, and labor-intensive. Therefore, to better achieve the function of convenient and quick roll-up of the film on both sides during ventilation, promote technological progress in the industry, and improve core technological competitiveness, this application proposes a new ventilation structure for drying sheds that differs from existing technologies. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of cumbersome operation, time and labor costs in the existing method, and to propose a ventilation structure for drying yellow tobacco.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilation structure for a drying shed for yellow tobacco includes a shed frame. Side films are provided on both sides of the shed frame, and a top film is provided on the top of the shed frame. Two first support rods and multiple second support rods are provided on the outer side of the shed frame. The two first support rods are located in the middle of the outer side of the shed frame, and the multiple second support rods are located at the four corners of the outer side of the shed frame. Two sliding rods are fixedly connected between two opposing second support rods. Multiple first sliding rings are slidably sleeved on the outer wall of the sliding rods, and the first sliding ring at one end of the sliding rod is fixed to that end of the sliding rod by bolts. A lead screw is rotatably mounted on the top of the two first support rods via an embedded bearing. Multiple second sliding rings are slidably sleeved on the outer wall of the lead screw. A threaded cylinder is threadedly connected to the outer wall of the lead screw. Clamping mechanisms are provided on the top of the threaded cylinder, the top of the second sliding rings, and the top of the first sliding rings. The top film is clamped on the clamping mechanisms. First connecting rods are fixedly connected to two of the first sliding rings on each side of the threaded cylinder. A second connecting rod is fixedly connected between every two opposing first sliding rings.

[0007] Furthermore, two crossbars are fixedly connected between the inner walls of both sides of the greenhouse frame, and multiple placement rods are fixedly connected between the two crossbars.

[0008] Furthermore, a mounting plate is fixedly connected to one side of one of the first support rods, and a motor is fixedly connected to the top of the mounting plate. The output end of the motor is fixedly connected to one end of the lead screw.

[0009] Furthermore, a protective cover is fixedly connected to the top of the mounting plate, and the protective cover is located on the outside of the motor.

[0010] Furthermore, a control panel is fixedly connected to one side of one of the first support rods, and the control panel is electrically connected to the motor.

[0011] Furthermore, the clamping mechanism includes a mounting base, with fixing bolts threaded to both ends of the mounting base, and a clamping plate rotatably connected to one end of each fixing bolt.

[0012] Furthermore, a rubber pad is adhered to one side of the clamp.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor, the lead screw rotates, causing the threaded cylinder to move along the lead screw. Then, under the connection of the first and second connecting rods, the first and second slip rings move along the sliding rod and the lead screw, thereby opening the top film and ventilating the greenhouse. The operation is simple, time-saving, and labor-saving.

[0015] 2. By tightening the fixing bolts, the two clamps are brought together in the middle, thereby clamping the corresponding part of the top film, which facilitates the fixing of the top film and allows for pulling of the top film, thus facilitating ventilation of the greenhouse.

[0016] 3. The rubber pads increase the friction between the top film and the clamping plate, thus improving the stability of the top film clamping. Attached Figure Description

[0024] 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.

[0025] Reference Figures 1-6 A ventilation structure for a drying shed for yellow tobacco includes a shed frame 1, with side films 2 on both sides of the shed frame 1 and a top film 18 on the top. Two first support rods 5 and multiple second support rods 6 are located on the outer side of the shed frame 1. The two first support rods 5 are positioned in the middle of the outer side of the shed frame 1, and the multiple second support rods 6 are positioned at the four corners of the outer side of the shed frame 1. Two sliding rods 7 are welded between opposing second support rods 6. Multiple first sliding rings 13 are slidably sleeved on the outer wall of the sliding rods 7, and the first sliding ring 13 at one end of the sliding rod 7 is fixed to that end of the sliding rod 7 by bolts. A lead screw 8 is rotatably mounted on the top between the two first support rods 5 via an embedded bearing. Multiple second sliding rings 1301 are slidably sleeved on the outer wall of the lead screw 8. A threaded cylinder 9 is threadedly connected to the outer wall of the lead screw 8. The top of the threaded cylinder 9 and the second sliding rings 1301 are connected to the lead screw 8. Both the top of 301 and the top of the first slip ring 13 are equipped with clamping mechanisms. The top film 18 is clamped on the clamping mechanisms. The two sides of the threaded cylinder 9 are respectively fixed with first connecting rods 17 between two of the first slip rings 13 by bolts. Among the four first slip rings 13, each pair of upper and lower opposing first slip rings 13 are fixed with second connecting rods by bolts. One side of one of the first support rods 5 is welded with a mounting plate 14. The top of the mounting plate 14 is fixed with a motor 15 by bolts. The output end of the motor 15 is fixedly connected to one end of the lead screw 8. Driven by the motor 15, the lead screw 8 rotates, thereby causing the threaded cylinder 9 to move along the lead screw 8. Then, under the connection of the first connecting rod 17 and the second connecting rod, the first slip ring 13 and the second slip ring 1301 move along the slide rod 7 and the lead screw 8, thereby opening the top film 18 and facilitating ventilation of the greenhouse.

[0026] Two horizontal bars 3 are welded between the inner walls of both sides of the greenhouse frame 1, and multiple placement bars 4 are welded between the two horizontal bars 3. The tobacco leaves are placed on the placement bars 4, which facilitates the drying of the tobacco leaves.

[0027] A protective cover 16 is fixed to the top of the mounting plate 14 by bolts. The protective cover 16 is located outside the motor 15, which facilitates the protection of the motor 15.

[0028] One of the first support rods 5 has a control panel 19 fixed to one side by bolts, and the control panel 19 is electrically connected to the motor 15.

[0029] The clamping mechanism includes a mounting base 10, with fixing bolts 11 threaded to both ends of the mounting base 10. A clamping plate 12 is rotatably connected to one end of the fixing bolts 11. Tightening the fixing bolts 11 causes the two clamping plates 12 to converge towards the middle, thereby clamping the corresponding portion of the top film 18. A rubber pad is adhered to one side of the clamping plate 12, thereby increasing the friction between the top film 18 and the clamping plate 12 and improving the stability of clamping the top film 18.

[0030] The working principle of this embodiment is as follows: When in use, firstly, the first support rod 5 and the second support rod 6 are inserted into the soil, and the first support rod 5 is set on the outer side of both ends of the center line of the greenhouse frame 1, and the second support rod 6 is set on the outer side of the four corners of the greenhouse frame 1. Then, the top film 18 is laid on the greenhouse frame 1, and the fixing bolts 11 are tightened to make the two clamping plates 12 converge towards the middle, thereby clamping the corresponding part of the top film 18, thus protecting the greenhouse.

[0031] When ventilation is needed, the motor 15 is started via the control panel 19. Driven by the motor 15, the lead screw 8 rotates, causing the threaded cylinder to move along the lead screw 8. Then, under the connection of the first connecting rod 17 and the second connecting rod, the first slip ring 13 and the second slip ring 1301 move along the slide rod 7 and the lead screw 8, thereby opening the top film 18 and facilitating ventilation of the greenhouse.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
