Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, in particular to a film covering device for tobacco fields. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or limited perennial herb with glandular hairs all over. The root is thick. The stem is 0.7-2 meters high and slightly lignified at the base. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with a gradually pointed apex and a gradually narrowed base until the stem becomes ear-shaped and semi-amplexicaulous. The inflorescence is terminal, conical, and multi-flowered; the pedicel is 5-20 mm long. The capsule is ovate or oblong, about the same length as the persistent calyx. The seeds are round or broadly oblong, about 0.5 mm in diameter, and brown. It blooms and bears fruit in summer and autumn. Transplanting tobacco leaves on film is a method of tobacco leaf transplanting that has been rapidly promoted in recent years. After the tobacco field is ridged, the ridge body needs to be covered with film. When covering the film, it should be widened and straightened, and the film should be pressed tightly with soil around it.

[0003] However, during the film laying operation, large film laying machines have great limitations due to the restrictions of the operating environment. Another manual film covering method is to insert a rod into the hollow cylinder of the film roll, and then two people lift the two ends respectively and walk to cover the film. This method requires at least two people to operate, and the labor efficiency is low.

[0004] Therefore, those skilled in the art provide a film covering device for tobacco fields to solve the problems raised in the above background technology. Utility Model Content

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes. Example 1

[0023] See also Figures 1 to 7 In this embodiment, a film covering device for tobacco fields is provided, including a traction frame 1 and a connecting plate 2, a fixed frame 3 is fixed to the rear of the connecting plate 2, a rotating shaft 4 is arranged inside the fixed frame 3, a pulling frame 5 is rotatably connected to the rotating shaft 4, the upper end of the pulling frame 5 is connected to a handle 6, two cross bars 7 are arranged inside the handle 6, a rubber pulling block 8 is arranged at a position of the handle 6 away from the pulling frame 5, and the user pulls the rubber pulling block 8, which is more comfortable to hold, and moves the traction frame 1;

[0024] A connecting block 9 is fixed to the right side of the outside of the traction frame 1, a sleeve 10 is fixed to the left side of the connecting block 9, an internal thread is provided on the inner wall of the sleeve 10, a mounting shaft 11 is fixed to the left side of the sleeve 10, a connecting screw 12 is sleeved inside the sleeve 10, an external thread matching the internal thread is provided on the outer wall of the screw 12, one end of the sleeve 10 is open, one end of the screw 12 is screwed into the sleeve 10, and a hand wheel 14 is installed at the other end of the screw 12; a center hole opened by a limit plate 13 is provided on the left side of the screw 12, and the limit plate 13 is rotatably installed at one end of the screw 12 close to the hand wheel 14;

[0025] The limit plate 13 is rotatably mounted on the screw 12 through a bearing, the screw 12 penetrates the inner ring of the bearing and is fixed, and the outer ring of the bearing is fixedly mounted in the center hole of the limit plate 13;

[0026] The limiting plate 13 is circular, and the handle 6 is an n-shaped structure. Two fixed blocks 15 are arranged at the bottom of the front side of the connecting plate 2. The lower end of the fixed block 15 is connected to a universal wheel 16. The universal wheel 16 is convenient for moving the traction frame 1. A fixed rod 17 is arranged between the two fixed blocks 15. Two vertical rods 18 are arranged at the bottom of the fixed rod 17. A rotating shaft 29 is fixed between the vertical rods 18. A limiting roller 20 is fixed on the rotating shaft. The limiting roller 20 limits the sleeved roll film when in use, and the use effect is good. A connecting frame 21 is arranged at the front of the fixed rod 17, and a connecting block 22 is arranged on the outer side of the connecting frame 21.

[0027] The screw rod 12 is then screwed into the sleeve 10 by the hand wheel 14, and the sleeve 10 is then inserted into the hollow tube of the film roll. The screwing amount of the screw 12 into the sleeve 10 determines the length of the sleeve 10 and the screw 12 after the combination. Since the length of the sleeve 10 and the screw 12 can be adjusted by the screwing amount of the screw 12, film rolls with different width parameters can be installed; the limit plate 13 is rotatably installed on one end of the screw 12 close to the hand wheel 14, and the limit plate 13 can limit the film roll to prevent the film roll from falling out from the end of the installation hand wheel 14, and the limit plate 13 is rotatably installed in the film roll. The purpose of the limit plate 13 being rotatably installed is that even if the friction force drives the limit plate 13 to rotate during the rotation of the film roll, it will not cause the screw 12 to rotate together, thereby preventing the screwing amount of the screw 12 from changing.
