Description
Technical Field
[0001] This utility model relates to the technical field of tobacco leaf picking equipment, and in particular to a multifunctional portable tobacco leaf picking aid. Background Technology
[0002] In the tobacco planting industry, tobacco leaf picking is a crucial and labor-intensive process. Traditional tobacco leaf picking mainly relies on manual harvesting, which has many drawbacks. On the one hand, manual harvesting is inefficient. With the continuous expansion of tobacco planting scale, manual harvesting can no longer meet production needs, leading to a longer harvesting cycle and affecting the subsequent processing and quality of tobacco leaves. On the other hand, when picking manually, tobacco farmers need to bend over or stretch their bodies for a long time to pick tobacco leaves at different heights. This not only easily causes physical fatigue for tobacco farmers, but may also damage the tobacco leaves due to improper harvesting movements, reducing the quality of the tobacco leaves.
[0003] In recent years, although some tobacco harvesting aids have emerged, these devices generally suffer from problems such as limited functionality and poor applicability. Some harvesting aids cannot be adjusted according to the height of tobacco farmers, making it difficult for farmers of different heights to operate comfortably, thus affecting harvesting efficiency and experience. Moreover, most existing harvesting aids require tobacco farmers to operate them by hand, preventing them from moving freely during the harvesting process. Their hands are also occupied, making it difficult to perform other auxiliary operations, such as timely sorting of harvested tobacco leaves or carrying other necessary tools. Furthermore, the existing harvesting equipment is not designed with full consideration for the ease of operation for tobacco farmers in complex field environments, resulting in poor portability and increasing the labor burden on tobacco farmers. These problems seriously restrict the efficient progress of tobacco harvesting.
[0004] To address these shortcomings, we have proposed a multifunctional portable tobacco leaf picking aid. Utility Model Content

[0023] Please refer to Figure 1-3A multifunctional portable tobacco leaf picking aid includes a support rod 2 and an adjusting rod 1. The adjusting rod 1 is inserted into the support rod 2, and one end of the adjusting rod 1 has a battery compartment 8 containing a battery 9. A battery cover 10 is threaded onto one end of the adjusting rod 1 corresponding to the position of the battery compartment 8. A shoulder strap 11 is detachably mounted on the adjusting rod 1. A hand screw 3 is threaded onto the surface of the support rod 2, and a fastening plate 4 is mounted on one end of the hand screw 3, with the surface of the fastening plate 4 abutting against the surface of the adjusting rod 1. A drive motor 5 is fixedly mounted on the support rod 2, and the output end of the drive motor 5 drives the cutting blade 7 to rotate via a synchronous pulley set 6.
[0024] When using the device, the tobacco farmer first loosens the two hand-tightening screws 3 symmetrically distributed on the surface of the support rod 2 according to their own height. Since both the adjusting rod 1 and the support rod 2 have rectangular cross-sections, this design effectively prevents the adjusting rod 1 from rotating inside the support rod 2, ensuring the stability of the adjustment. After loosening the hand-tightening screws 3, the adjusting rod 1 can slide up and down inside the support rod 2. The tobacco farmer adjusts the adjusting rod 1 to a suitable height so that the harvesting aid can be adapted to their operating habits and physical conditions. Then, tighten the hand-tightening screws 3. The fastening plate 4 at one end of the hand-tightening screw 3 will then firmly press against the adjusting rod 1, thereby fixing the position of the adjusting rod 1. Next, the tobacco farmer comfortably wears the carrying strap 11. The protective pad on the carrying strap 11, which is attached by Velcro, effectively reduces the pressure of the carrying strap 11 on the body and increases the wearing comfort. The battery 9 is placed in the battery compartment 8 at one end of the adjusting rod 1 beforehand, and the battery cover 10 is tightened to ensure that the battery is installed securely and will not be damaged by the fastening screws 3. Shaking affects equipment operation. After preparation, the tobacco farmer presses the control switch 12 on the adjusting rod 1. The control switch 12 connects the circuit of the drive motor 5 and the battery 9 through the wire. The drive motor 5 starts to work, and the output of the drive motor 5 drives the synchronous belt pulley group 6 to rotate, which in turn drives the cutting blade 7 to rotate at high speed. At this time, the tobacco farmer holds the picking aid and aligns the high-speed rotating cutting blade 7 with the stem of the tobacco leaf and cuts it gently to complete the picking of the tobacco leaf. During the picking process, the tobacco farmer's hands are freed, and he can walk freely in the field. He can also use his hands to sort the picked tobacco leaves at any time and place them in a suitable container, or carry tools such as scissors to trim the tobacco leaves. This greatly improves the picking efficiency and operation convenience. The protective cover set at the position of the drive motor 5 and the synchronous belt pulley group 6 can effectively prevent the rotating parts from causing accidental injury to the tobacco farmer during the picking process and ensure the personal safety of the tobacco farmer.
[0025] In this embodiment: a control switch 12 is installed on the adjusting rod 1, and the control switch 12 is electrically connected to the drive motor 5 and the storage battery 9 through wires.
[0026] Specifically, the control switch 12 is a waterproof, dustproof, and easy-to-operate push-button switch, installed on the adjusting rod 1 near the tobacco farmer's hand, so that the tobacco farmer can easily reach it after wearing the harvesting aid. The wire is made of rubber soft wire with good insulation performance. The cross-sectional area of the copper core wire inside has been accurately calculated to ensure sufficient current transmission to meet the power requirements of the drive motor 5, while preventing problems such as overheating and short circuits caused by excessive current. The wire is reasonably routed inside the adjusting rod 1 and the support rod 2 and fixed with cable ties and other fixing devices to prevent the wire from shaking or getting tangled during equipment use, which would affect the normal operation of the equipment.
[0027] In this implementation scheme: the cross-sections of both the adjusting rod 1 and the support rod 2 are rectangular.
[0028] Specifically, the rectangular cross-section design increases the friction between the adjusting rod 1 and the support rod 2. After the adjusting rod 1 is adjusted to a suitable height and fixed by the hand screw 3 and the fastening plate 4, it can effectively prevent the adjusting rod 1 from sliding up and down due to external forces or its own weight, ensuring the stability of the harvesting aid during use. At the same time, the rectangular cross-section also facilitates the installation of other components on the adjusting rod 1 and the support rod 2, such as the hand screw 3 and the drive motor 5, making the overall structure of the equipment more compact and reasonable. The rectangular cross-section dimensions of the adjusting rod 1 and the support rod 2 are designed according to the overall strength requirements of the equipment and the actual use scenario, ensuring that the equipment is lightweight while having sufficient load-bearing capacity and stability.
[0029] In this implementation plan: a protective pad is attached to the shoulder strap 11 by Velcro.
[0030] Specifically, the protective pad is made of soft, breathable, and elastic sponge material. The surface of the sponge is covered with a layer of skin-friendly cotton fabric, which increases the comfort of contact with the tobacco farmer's body, absorbs sweat and is breathable, and avoids skin discomfort caused by prolonged wear. The Velcro has male and female sides, which are sewn onto the shoulder strap 11 and the protective pad respectively. The male and female sides have a large area to ensure the adhesion is firm and prevent the protective pad from falling off during use. The shape of the protective pad is ergonomically designed to fit the curves of the tobacco farmer's shoulders and back, effectively distributing the pressure of the shoulder strap 11 on the body and reducing the fatigue of the tobacco farmer during long harvesting periods.
[0031] In this embodiment, there are two hand-tightening screws 3, and the two hand-tightening screws 3 are symmetrically distributed on the surface of the support rod 2.
[0032] Specifically, two hand-tightening screws 3 are symmetrically distributed on the surface of the support rod 2. This design allows the fastening plate 4 to apply uniform pressure to the adjusting rod 1 when fixing it, ensuring that the adjusting rod 1 will not tilt or wobble after being fixed. The hand-tightening screws 3 are made of high-strength metal material, such as stainless steel, and their threads are finely machined to ensure a tight fit with the threaded holes on the support rod 2. The operation is smooth during tightening and loosening, and the threads are not easy to strip. The head of the hand-tightening screw 3 is designed with a large circular or hexagonal grip, which is convenient for tobacco farmers to operate with their hands. Even in the field environment, when hands may be covered with mud or sweat, the hand-tightening screws 3 can be easily tightened or loosened.
[0033] In this implementation plan, protective covers are provided at the positions of the drive motor 5 and the synchronous pulley group 6.
[0034] Specifically, the protective cover is made of high-strength, corrosion-resistant engineering plastics, such as ABS plastic. This material has good mechanical properties and weather resistance, and can effectively resist the harsh environment in the field, such as rain and sun exposure. The shape of the protective cover is designed according to the structure of the drive motor 5 and the synchronous pulley set 6, completely covering the drive motor 5 and the synchronous pulley set 6 to prevent tobacco leaves, debris, etc. from entering the rotating parts during the harvesting process and affecting the normal operation of the equipment. At the same time, it avoids the rotating parts from causing injury to tobacco farmers. The protective cover is installed on the support rod 2 by screws or buckles and other fixing devices. It is firmly installed and easy to disassemble, which facilitates the daily maintenance and repair of the drive motor 5 and the synchronous pulley set 6.
[0035] Working Principle: When using the device, the tobacco farmer first loosens the two symmetrically distributed hand-tightened screws 3 on the surface of the support rod 2, according to their own height. Since both the adjusting rod 1 and the support rod 2 have rectangular cross-sections, this design effectively prevents the adjusting rod 1 from rotating within the support rod 2, ensuring adjustment stability. After loosening the hand-tightened screws 3, the adjusting rod 1 can slide up and down within the support rod 2. The farmer adjusts the adjusting rod 1 to a suitable height, ensuring the harvesting aid matches their operating habits and physical condition. Then, the farmer tightens the hand-tightened screws 3, causing the fastening plate 4 at one end of the screw 3 to firmly press against the adjusting rod 1, thus fixing its position. Next, the farmer comfortably wears the carrying strap 11. The protective pads on the carrying strap 11, secured by Velcro, effectively reduce pressure on the body and increase wearing comfort. The battery 9 is placed in the battery compartment 8 at one end of the adjusting rod 1, and the battery cover 10 is tightened to ensure the battery is securely installed. The shaking may affect the operation of the equipment. After the preparation is completed, the tobacco farmer presses the control switch 12 on the adjustment rod 1. The control switch 12 connects the circuit of the drive motor 5 and the battery 9 through the wire. The drive motor 5 starts to work. The output end of the drive motor 5 drives the synchronous belt pulley group 6 to rotate, which in turn drives the cutting blade 7 to rotate at high speed. At this time, the tobacco farmer holds the picking aid and aligns the high-speed rotating cutting blade 7 with the stem of the tobacco leaf and cuts it gently to complete the picking of the tobacco leaf. During the picking process, the tobacco farmer's hands are freed. He can walk freely in the field and can also sort the picked tobacco leaves by hand at any time and place them in a suitable container, or carry tools such as scissors to trim the tobacco leaves. This greatly improves the picking efficiency and operation convenience. The protective cover set at the position of the drive motor 5 and the synchronous belt pulley group 6 can effectively prevent the rotating parts from causing accidental injury to the tobacco farmer during the picking process and ensure the personal safety of the tobacco farmer.
