Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco planting equipment, specifically relating to a device for removing flue-cured tobacco stems. Background Technology

[0002] Tobacco is one of my country's important economic crops, and my country is the world's largest producer of tobacco leaves. During the tobacco planting process, after the tobacco leaves are harvested, tobacco stalks are left in the tobacco fields. These stalks contain a large number of pathogens, which, if allowed to rot, can directly infect the tobacco leaves planted the following year, and in severe cases, can even cause a complete crop failure. Tobacco stalks and roots are neither suitable for burning as fuel nor for direct application as fertilizer to the field. To ensure the income of tobacco farmers and the stability of the tobacco industry, and to enable the sustainable development of tobacco production, it is essential to maintain proper hygiene in tobacco planting, thoroughly remove the tobacco stalks and roots left in the fields, and burn or dispose of them away from the fields to prevent the pollution of the agricultural environment by tobacco waste.

[0003] Currently, tobacco stalks are mostly removed manually by tobacco farmers, which is labor-intensive, time-consuming, and labor-intensive. Although some tobacco stalk removal machines have been introduced to the market, which have improved the removal efficiency to some extent, they do not remove the stalks completely and often miss some, requiring further manual removal. This affects the efficiency of tobacco stalk removal and makes them unsuitable for use in smaller tobacco fields with complex terrain, resulting in poor flexibility. Therefore, we propose a tobacco stalk removal device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a tobacco stem removal device, including a crossbar 1, a connecting block 2 at the bottom of one side of the crossbar 1, a first fixing shaft 4 at the bottom of the connecting block 2, a base 5 at the bottom of the first fixing shaft 4, a first U-shaped rod 6 at one end of the crossbar 1, a second U-shaped rod 8 at one side of the first U-shaped rod 6, a first row of teeth 9 at one side of the inner side of the second U-shaped rod 8, a lead screw 10 at one end of the second U-shaped rod 8, a clamping plate 11 at one end of the lead screw 10, and a second row of teeth 12 at one side of the clamping plate 11.

[0019] Specifically, a connecting block 2 is fixedly installed on the bottom surface of one side of the crossbar 1. The bottom of the connecting block 2 is rotatably connected to the top of the upright 3 through a first fixed shaft 4. The bottom of the first fixed shaft 4 is fixedly connected to the middle of the surface of the base 5. One end of the crossbar 1 is fixedly connected to the first U-shaped rod 6 through a second fixed shaft 7. A second U-shaped rod 8 is fixedly installed on one side of the first U-shaped rod 6. A first row of teeth 9 is fixedly installed on one side of the inner surface of the second U-shaped rod 8. A lead screw 10 is threaded through one end of the second U-shaped rod 8. A clamping plate 11 is rotatably connected to one end of the lead screw 10. A second row of teeth 12 is fixedly installed on one side of the clamping plate 11. A telescopic rod 13 is fixedly connected to one side of the clamping plate 11. The bottom end of the telescopic rod 13 is fixedly connected to the second U-shaped rod 8. A handle 14 is fixedly installed on one end of the crossbar 1.

[0020] In this embodiment, the diameter of the flue-cured tobacco rod is adjusted as needed. The distance between the clamp plate 11 and the inner wall of the second U-shaped rod 8 is adjusted by rotating the screw 10. In specific use, the root of the tobacco rod is placed between the first row of teeth 9 and the second row of teeth 12. The bottom of the base 5 contacts the ground and is supported by it. The rotational connection between the upright rod 3 and the crossbar 1 is achieved according to... Figure 1 Press down on the left end of the horizontal bar 1. Using the top of the vertical bar 3 as a support point, the lever principle is realized. The right end of the horizontal bar 1 will tilt upward. Through the clamping between the first row of teeth 9 and the second row of teeth 12 and the surface of the tobacco rod, the root of the tobacco rod can be separated from the ground, thus achieving the effect of removing the tobacco rod.
