Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco planting technology, specifically a portable electric aperitone machine for flue-cured tobacco. Background Technology

[0002] The electric tobacco hole-drilling machine is an electric agricultural machine specifically used for hole-drilling operations during tobacco planting. The electric hole-drilling machine uses an electric motor to drive a drill bit or spiral blade to dig holes in the soil and make wells. It is mainly used for hole-drilling operations before transplanting crops such as flue-cured tobacco, vegetables, and flowers.

[0003] Some existing electric hole-drilling machines for flue-cured tobacco are still too bulky, making them inconvenient for growers to carry. They are especially unsuitable for small plots of land such as mountainous areas and terraced fields. Furthermore, the lack of protective measures around the holes during the drilling process causes soil to fly everywhere. Flying soil clods and gravel may hit the operator or nearby people. Moreover, the top fertile soil is thrown far away, which reduces the nutrient content around the holes.

[0004] For example, Chinese Patent Publication No. CN221488332U proposes a transplanter for flue-cured tobacco planting that facilitates hole drilling. This transplanter includes a base plate with a drive assembly on it. The drive assembly has a rotating rod with a mounting groove. The rotating rod also has a hole-drilling assembly for drilling holes. At the end of the rotating rod away from the hole-drilling assembly, there is a clamping assembly for holding the tobacco leaves. The transplanter is moved to the desired position using casters. The drill bit position is adjusted using an electric push rod, and a second motor is activated to drive the drill bit to drill holes. A third motor drives a threaded rod to rotate, causing two mounting blocks to move inward to clamp the tobacco leaves. A first motor then drives a drive gear to rotate, causing a driven gear to rotate, which in turn rotates the rotating rod, moving the clamping assembly to the original position of the hole-drilling assembly for transplanting. However, this transplanter suffers from the aforementioned problems; it is relatively bulky and inconvenient to carry, making it more suitable for operation in flat areas.

[0005] Therefore, in order to solve the above problems, it is necessary to propose a portable and easy-to-operate electric tobacco curing machine to meet the needs of small plots of land such as mountainous areas and terraced fields. Utility Model Content

[0006] The purpose of this utility model is to provide a portable electric tobacco drilling machine, which aims to solve the problems of existing electric drilling machines, which are not suitable for operation in small plots such as mountainous areas and terraced fields, are not convenient to carry, and lack protective measures around the drilling process, resulting in soil flying everywhere. The flying soil and gravel may hit the operator or nearby people, and the fertile topsoil is thrown far away, which will reduce the nutrient content around the hole.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A portable electric tobacco curing acupuncture machine includes a mounting frame, a power supply body, a connecting component, a support rod, a protective shell, a motor, a drill bit, and a protective mechanism.

[0027] 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.

[0028] Please see Figure 1 and 6 This utility model provides a portable electric auger for tobacco curing, including a mounting frame 1, a power supply body 2, a connecting assembly 3, a support rod 4, a protective shell 5, a motor 6, a drill bit 7, and a protective mechanism 8. The mounting frame 1 is L-shaped, and the power supply body 2 is installed within the space enclosed by the mounting frame 1. The motor 6 is installed inside the protective shell 5, and the power supply body 2 and the motor 6 are electrically connected. The output shaft of the motor 6 is fixedly connected to the upper end of the drill bit 7. In this embodiment, the power supply body 2 uses a lithium-ion battery, which has the advantage of high energy density and smaller size and weight for the same amount of power, which is beneficial to the portable design of the auger. The power supply body 2 provides power to the motor 6, so that the motor 6 can drive the drill bit 7 to rotate and make holes in the soil.

[0029] In this embodiment, as Figures 1-2 The support rod 4 shown is foldable, which facilitates storage when not in use, reduces space occupation, and enhances the portability of the hole-drilling machine, making it convenient for growers to carry and operate in small plots such as mountainous areas and terraced fields. The lower end of the support rod 4 is fixedly connected to the top of the protective shell 5, and the upper end of the support rod 4 is fitted with an anti-slip sleeve 10. A controller 11, which controls the motor 6, is also installed on the upper end of the anti-slip sleeve 10. The controller 11 is electrically connected to the power supply body 2.

[0030] The anti-slip sleeve 10 protects the hands and prevents slipping, preventing direct contact between the hands and the support rod 4 during use and increasing the grip strength of the hand on the support rod. The controller 11 can control the start, stop and speed of the motor 6, thereby controlling the working state of the drill bit 7.

[0031] like Figure 2As shown, the protective mechanism 8 includes a protective cover 81, the upper end of which is fitted onto the lower end of the outer wall of the protective shell 5. The drill bit 7 is located inside the protective cover 81. A limiting seat 82 is fixedly connected to the upper circumference of the protective cover 81. A threaded groove 83 is provided on the limiting seat 82. The lower end of the limiting mechanism 9 is threadedly connected to the threaded groove 83 of the limiting seat 82. The upper end of the limiting mechanism 9 is movably connected to the surface of the protective shell 5. The limiting seat 82 is fixed to the upper circumference of the protective cover 81. The threaded groove 83 is provided on the limiting seat 82 and cooperates with the limiting mechanism 9. The position of the protective cover 81 is adjusted through the threaded connection. When the drill bit 7 is working, the protective cover 81 can block soil, gravel, etc., splashed during drilling, effectively preventing soil from splashing everywhere and preventing splashed soil and gravel from hitting the operator or nearby personnel. It also prevents the top fertile soil from being scattered far away, maintaining the nutrient content around the hole, protecting the working environment and personnel safety, and also improving planting results.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, the limiting mechanism 9 includes a limiting rod 91. The lower end of the limiting rod 91 has a thread 92 that mates with the threaded groove 83 of the limiting seat 82. The upper end of the limiting rod 91 passes through the protective shell 5 via a sliding sleeve 95 and extends upward. The sliding sleeve 95 is embedded in the outer wall of the protective shell 5. Figure 5 As shown, a limiting block 93 is fixedly connected to the top of the limiting rod 91, and a spring 94 is fixedly connected to the lower surface of the limiting block 93. The spring 94 is sleeved on the outside of the limiting rod 91, and the lower end of the spring 94 is fixed on the protective shell 5.

[0033] like Figure 1 and Figure 2 The protective cover 81 is horn-shaped and made of rubber. The horn-shaped design gives the protective cover 81 a larger coverage area when blocking splashes, and can better collect and block soil and gravel that are splashed in all directions during drilling. The rubber material has good flexibility and wear resistance, which ensures the protective effect while not being easily damaged by collision, and can effectively buffer the impact force during drilling.

[0034] When the drill bit 7 drills downwards, the protective cover 81 is resisted by the soil. The limiting rod 91 moves upwards against the elastic force of the spring 94 through the limiting seat 82, adjusting the position of the protective cover 81. When drilling ends, the spring 94 returns to its original deformation, driving the limiting rod 91 and the protective cover 81 to reset. The limiting mechanism 9 facilitates the flexible adjustment of the protective cover 81 according to the drilling depth of the drill bit 7, improving the practicality and adaptability of the protective mechanism 8, ensuring effective protection at different drilling depths, and further enhancing the protection of personnel and the working environment.

[0035] like Figure 3As shown, the connecting assembly 3 includes a connecting block 31, which is fixedly positioned symmetrically on the top of one side of the mounting bracket 1. A shoulder strap 32 is mounted on the connecting block 31, and a buckle 33 is provided at one end of the shoulder strap 32. A mounting bracket 34, which cooperates with the buckle 33, is fixedly connected to the mounting bracket 1 at a position symmetrical to the connecting block 31. One end of the shoulder strap 32 is mounted on the connecting block 31, and the buckle 33 at the other end of the shoulder strap 32 cooperates with the mounting bracket 34 at a symmetrical position on the mounting bracket 1.

[0036] The carrying strap 32 is woven with interlaced warp and weft threads. The warp and weft threads of the carrying strap 32 are made of nylon. Nylon threads have the characteristics of high strength and good wear resistance, which can withstand the weight of the acupuncture machine and are not easy to break, thus ensuring the service life of the carrying strap 32, improving the durability of the carrying strap 32, and reducing the situation where the use of the acupuncture machine is affected by the damage to the carrying strap 32.

[0037] When in use, the shoulder strap 32 is passed through the body and the buckle 33 is fastened, so that the mounting frame 1 and the power supply body 2 can be carried on the back of the worker, realizing the backpack-style carrying of the hole-drilling machine. This makes the electric hole-drilling machine for tobacco curing suitable for small plots of land such as mountainous areas and terraced fields, greatly improving the portability of the equipment and making it convenient for planting personnel to work in complex terrain.

[0038] The surface of the carrying strap 32 is fitted with a protective strap 12, and the inside of the protective strap 12 is filled with sponge 13. The protective strap 12 can distribute the pressure of the carrying strap 32 on the body. The sponge 13 has good elasticity and cushioning performance, which can further reduce the pressure of the carrying strap 32 on the body, making the carrying more comfortable, reducing physical fatigue caused by carrying for a long time, and helping to improve work efficiency and working time.

[0039] It is worth noting that, such as Figure 3 As shown, a fixing block 14 is provided between two adjacent connecting blocks 31 and the card holder 34. There are four fixing blocks 14, and each pair of fixing blocks 14 corresponds to the other. A perforated plate 15 is installed at one end of the fixing block 14. The perforated plate 15 and the mounting frame 1 form a ventilation channel, which plays a role in ventilation and heat dissipation, reducing the temperature of the equipment during use and ensuring stable operation of the equipment. A cushion 16 is installed on the outer side of the perforated plate 15. When the staff carries the acupuncture machine, the cushion 16 fits against the back of the person, increasing comfort.
