Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf drying technology, specifically a drying pole fork. Background Technology

[0002] Cigar tobacco leaf air-drying involves harvesting fresh tobacco leaves that have reached a certain maturity in the field, placing them in a specific drying room, and maintaining necessary temperature and humidity conditions for a certain period of time. This allows the tobacco leaves to change to the desired degree, including the most direct quality indicators such as appearance (color) and internal flavor characteristics. After harvesting, the fresh tobacco leaves are strung together by threading steel wire or cotton thread horizontally through the main vein 1.8–2.3 cm from the leaf petiole. Each string is 190–200 cm long and contains 70–90 leaves. The ends of the steel wire or cotton thread are then fixed to the ends of bamboo poles, which are then hung in the drying room at 20–25 cm intervals. To save on drying room construction land and costs, domestic cigar tobacco producing areas generally design the hanging racks in the drying rooms to have 4–7 layers.

[0003] According to patent number CN 213215288 U, a cigar tobacco drying pole includes a support rod and a support frame placed on top of the support rod. The support frame is an isosceles triangular support frame with its apex pointing downwards and connected to the upper part of the support rod. This allows a single person to stand on the ground and complete the work of placing fresh cigar tobacco leaves on the rack, removing dry tobacco leaves from the rack, and adjusting the distance between the tobacco poles according to the temperature and humidity in the drying room. However, this pole requires manual operation to complete the work of placing fresh cigar tobacco leaves on the rack, removing dry tobacco leaves from the rack, and adjusting the distance between the tobacco poles according to the temperature and humidity in the drying room, which consumes a lot of manpower. Therefore, we propose a drying pole. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1 This utility model provides a technical solution: a drying pole fork, including a movable base 1, a mounting frame 4 fixedly connected to the top of the movable base 1, an electric push rod 5 installed inside the mounting frame 4, a lifting rod 6 fixedly connected to the piston rod end of the electric push rod 5, and the end of the lifting rod 6 slidingly passing through the mounting frame 4, a vertical pole 7 detachably connected to one end of the lifting rod 6 located outside the mounting frame 4, a mounting box 8 fixedly connected to the top of the vertical pole 7, and rotatable and adjustable support rods 9 symmetrically arranged at the bottom of the inner wall of the mounting box 8, with a fork 10 provided at the end of the support rod 9.

[0021] It should be noted that, when using this utility model, the upright pole 7 and the lifting rod 6 can be disassembled for use. For a small amount of tobacco leaves, the upright pole 7 can be held by hand, and the worm gear 18 can be rotated by turning the handwheel 19. The lead screw 11 can be rotated through the meshing connection between the worm gear 18 and the worm wheel 17. The lifting seat 12 can be raised through the threaded connection between the lead screw 11 and the lifting seat 12. Under the action of the adjusting rod 15, the two support rods 9 are pushed to unfold, so that the two support rods 9 and the upright pole 7 form a Y-shaped structure. The upright pole 7 can be held by hand. The pole 7, through the control of the fork 10, completes the work of placing fresh cigar tobacco leaves on the rack, removing dry tobacco leaves from the rack, and adjusting the distance between the tobacco poles according to the temperature and humidity in the drying room. When drying a large amount of tobacco leaves, the pole 7 can be fixed to the top of the lifting rod 6 with fixing screws. The two forks 10 lift the drying rods and place them in a higher position on the drying rack. Then, the cigar tobacco leaves are bundled on the forks 10. The electric push rod 5 controls the raising of the pole 7 in conjunction with the movement of the movable base 1, and the fresh leaves are placed on the rack for drying through the forks 10.

[0022] Please see Figure 2A support frame 16 is fixedly installed on the top of the mounting box 8, and a lead screw 11 is rotatably connected to the bottom of the inner wall of the mounting box 8 via a bearing. The end of the lead screw 11 is rotatably connected to the support frame 16. A lifting seat 12 is threadedly connected to the outer side of the lead screw 11, and an adjusting rod 15 is rotatably connected to the corresponding two side walls of the lifting seat 12. A strip groove 13 is opened in the support rod 9, and a slide 14 is fixedly connected in the strip groove 13. The end of the adjusting rod 15 is rotatably connected to the slide 14.

[0023] It should be noted that when the control screw 11 rotates, the lifting seat 12 can be adjusted by the threaded connection between the lifting seat 12 and the screw 11, thereby driving the lifting adjustment of one end of the two adjusting rods 15. Under the action of the adjusting rods 15, the support rod 9 can be pulled to rotate around its bottom end inside the mounting box 8. When the two support rods 9 are installed in the vertical position, the two support rods 9 are folded together, saving space and facilitating their transportation.

[0024] Please see Figure 1 The mounting box 8 has symmetrical arc-shaped grooves 20 on its corresponding two side walls, and the support rod 9 has symmetrical limit rods 21 on its corresponding two side walls, and the limit rods 21 are slidably connected in the arc-shaped grooves 20.

[0025] It should be noted that when the support rod 9 rotates inside the mounting box 8, the limiting rod 21 on the support rod 9 is slidably connected inside the arc groove 20, so that the support rod 9 can move smoothly inside the mounting box 8.

[0026] Please see Figure 1 The lifting rod 6 is integrally provided with a mounting plate at one end outside the mounting frame 4 and at the bottom of the upright 7, and the two mounting plates are fixed together by screws. The outer side of the bottom end of the upright 7 is provided with anti-slip texture.

[0027] It should be noted that the upright 7 and the lifting rod 6 are detachably connected. The mounting plate at the bottom of the upright 7 and the mounting plate at the top of the lifting rod 6 are connected by screws, which makes disassembly and assembly convenient. When disassembling, the support rod 9 and the fork 10 at its end can be operated by holding the upright 7.

[0028] Please see Figure 1 The top of the movable base 1 is symmetrically provided with mounting slots, and a counterweight 3 is installed in the mounting slot.

[0029] It should be noted that the counterweight 3 enhances the stability of the movable base 1.

[0030] Please see Figure 1 The surface of the movable base 1 is provided with a storage drawer 2.

[0031] It should be noted that storage drawer 2 is designed to store spare items for easy access.

[0032] Please see Figure 2 The top of the lifting seat 12 is fixedly connected to the worm gear 17 through the support frame 16. The top of the support frame 16 is rotatably connected to the worm 18, and the worm 18 is meshed with the worm gear 17. The end of the worm 18 is fixedly connected to the handwheel 19 through the support frame 16.

[0033] It should be noted that the worm 18 can be rotated by turning the handwheel 19, and the lead screw 11 can be rotated through the meshing connection between the worm 18 and the worm wheel 17.
