Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco planting auxiliary equipment, in particular to a mixer for small seedlings under the film of flue-cured tobacco. Background Technique

[0002] Flue-cured tobacco is a tobacco variety specifically used for making cigarettes and other tobacco products. During the flue-cured tobacco planting process, it is necessary to cover the film at a specific stage to protect the small seedlings. Such a film can provide the effects of heat preservation, moisture preservation or protection, which helps to improve the growth quality of the small seedlings. However, the soil under the film is usually blocked by the film, resulting in slower evaporation of the surface soil moisture, while the moisture in the underlying soil is more likely to be lost. This uneven distribution of moisture will cause the surface of the soil to form hardening, especially more obvious under dry or over-wet conditions. The compacted soil will lead to an increase in soil density, poor air and water permeability, thus restricting the growth and expansion of the roots of small seedlings. This will also cause the roots to be unable to fully absorb nutrients and water, affecting the growth and development of small seedlings.

[0003] Therefore, the utility model designs a mixer for small seedlings under the film of flue-cured tobacco. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a mixer for small seedlings under the film of flue-cured tobacco, so as to solve the problems in the prior art that the soil under the film is usually blocked by the film, resulting in soil compaction, and the compacted soil will lead to an increase in soil density, poor air and water permeability, thus restricting the growth and expansion of the roots of small seedlings.

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0021] Such as Figures 1-3As shown in the figure, the small-seedling mixer under the flue-cured tobacco film proposed by the present utility model includes a support disk 1 and a small-seedling body 3. The support disk 1 is provided with a convex edge for the operator to manually hold. The upper surface of the support disk 1 is fixedly connected with a support frame 16 for supporting the operation of the motor 15. The material of the support frame 16 is usually selected from alloy steel, stainless steel or aluminum alloy to ensure sufficient strength and corrosion resistance. The support frame 16 generally refers to the equipment component used to install and support the motor 15. The support frame 16 provides a stable platform for the motor 15 to be safely installed on the equipment or structure. At the same time, through appropriate design and material selection, the support frame 16 can reduce the vibration and noise generated during the operation of the motor, which helps to improve the stability and comfort of the equipment. The material of the support frame 16 can be stainless steel, which is a common choice and is favored for its corrosion resistance and strength. It is suitable for environments that require long-term use, frequent cleaning and contact with water or wet soil. Or carbon steel, a common material, is usually used in applications that require strength and economy. It may require additional rust-proof treatment to protect against soil and humidity. In addition, using aluminum alloy will have good strength and lightweight characteristics, which are suitable for some applications that require higher mobility and portability. It also includes: a plurality of stirring straight rods 26 and stirring bent rods 29 that are arranged in a circumferential array at the bottom of the support disk 1 and stir the soil. The materials of the stirring straight rods 26 and the stirring bent rods 29 are the same as that of the support disk 1. The stirring straight rods 26 are arranged in a circumferential array at the bottom of the connecting disk 14. The function is that when the plurality of stirring straight rods 26 rotate and stir the loose soil with the small-seedling body 3 as the center, the rotation trajectories of the stirring straight rods 26 can be the same. At the same time, through stirring, the soil structure can be improved to make it looser, increasing air permeability and water permeability. This helps to promote the growth of plant roots and improve the crop yield and quality. And there may be a problem of soil stratification, that is, different components are unevenly distributed in the vertical direction. By regularly stirring with the circumferentially distributed stirring rods, the occurrence of soil stratification can be effectively prevented. The stirring bent rods 29 at the bottom of the stirring straight rods 26 are all bent at an angle greater than 90°. When the bending angle of the stirring bent rod 29 is greater than 90°, a larger stirring area and stronger stirring force will be formed during stirring. This can loosen the soil more completely and avoid dead corners or un-loosened areas around the small seedlings. The top of the support disk 1 is provided with a motor 15 that drives the plurality of stirring straight rods 26 to rotate simultaneously. Using an AC motor for the motor 15 is a common type of electric motor and is suitable for most stirring equipment. They can provide stable power output and are suitable for applications that require long-term operation.A rotating mechanism for connecting the stirring straight rod 26 and the motor 15 is provided on the support disc 1; a positioning mechanism is provided at the bottom of the support disc 1 to prevent the small seedling body 3 from being damaged by the stirring bent rod 29 after being clamped. The positioning mechanism includes a positioning rod 22. Conical soil-inserting blocks 27 are fixedly connected to the bottom ends of the positioning rod 22, the stirring straight rod 26, and the stirring bent rod 29. The function of the conical soil-inserting blocks 27 is to enable the positioning rod 22, the stirring straight rod 26, and the stirring bent rod 29 to more easily penetrate and insert into the soil, especially for dense or viscous soil. This can reduce the resistance and effort of the stirring rod at the start of work, making the operation smoother and more efficient. At the same time, the design of the conical soil-inserting blocks 27 can reduce problems caused by soil blockage during operation. It can more easily penetrate uneven or obstacle-containing soil, avoiding interruptions or operational difficulties during the stirring process. Finally, the design of the conical soil-inserting blocks 27 can also provide better operation stability and controllability, enabling the operator to more accurately control the stirring depth and strength, thereby achieving the desired mixing effect.

[0022] A telescopic sleeve block 24 is slidably connected to the bottom of the positioning rod 22. A pair of arc-shaped positioning rods 28 for clamping the small seedling body 3 are fixedly connected to the outer wall of the telescopic sleeve block 24. A notch for the small seedling body 3 to be inserted is provided at the opposite ends of the pair of arc-shaped positioning rods 28 originally from the telescopic sleeve block 24. The function of the arc-shaped positioning rods 28 is to prevent the stirring straight rod 26 and the stirring bent rod 29 from damaging the small seedlings when stirring the soil around the small seedlings. And small seedlings are very sensitive to external environmental interference in the initial growth stage. If the bottom of the stirring rod accidentally collides with or inserts near the root system of the small seedlings, it will cause damage or destruction to the root system, affecting the growth and development of the small seedlings. At the same time, the reasonably designed arc-shaped positioning rods 28 can reduce the technical requirements for the operator because they can more easily avoid the small seedlings, thereby reducing human errors and unnecessary operation time and improving work efficiency. The arc-shaped positioning rods 28 are symmetrically arranged on both sides of the telescopic sleeve block 24.

[0023] Further, a clamping sleeve 23 is fixedly sleeved on the middle part of the positioning rod 22. A return spring 25 is slidably sleeved on the positioning rod 22 between the clamping sleeve 23 and the telescopic sleeve block 24. One end of the return spring 25 is fixedly connected to the clamping sleeve 23, and the other end of the return spring 25 is fixedly connected to the telescopic sleeve block 24. Its function is that when the arc-shaped positioning rods 28 clamp the soil and the conical soil-inserting block 27 at the bottom of the positioning rod 22 is inserted into the soil, the arc-shaped positioning rods 28 will always slide upward along the positioning rod 22, and when the positioning rod 22 is taken out of the soil, at this time, the telescopic sleeve block 24 will drive a pair of arc-shaped positioning rods 28 to return to their original positions through the elastic thrust of the return spring 25.

[0024] Among them, the rotating mechanism includes a rotating perforation 11 formed in the support disk 1. A rotating block 12 is movably connected inside the rotating perforation 11, and the inside of the rotating block 12 is hollow. A connecting block 13 is fixedly connected to the top of the rotating block 12, the upper surface of the connecting block 13 is fixedly connected to the output shaft of the motor 15, and a connecting disk 14 is fixedly connected to the lower surface of the rotating block 12. The lower surface of the connecting disk 14 is fixedly connected to the top end of the stirring straight rod 26.

[0025] Furthermore, the top end of the positioning rod 22 is fixedly connected to a rotating shaft 2, and the rotating shaft 2 is movably connected to the connecting disk 14. Its function is to prevent the arc-shaped positioning rod 28 from rotating after the connecting disk 14 rotates, so as to avoid damaging the small seedling body 3 after the arc-shaped positioning rod 28 rotates. The rotating shaft 2 is arranged at the central part of the connecting disk 14. Clamping blocks 21 that clamp the connecting disk 14 are fixedly sleeved on the upper and lower ends of the rotating shaft 2. The function of the clamping blocks 21 is to enable the rotating shaft 2 to only rotate on the connecting disk 14.

[0026] In this embodiment, when the flue-cured tobacco under-film small-seedling mixer needs to be used, as Figure 1 shown, it is only necessary to make a pair of arc-shaped positioning rods 28 on the telescopic sleeve block 24 clamp the small seedling body 3 planted in the soil. Then press down the support disk 1. Finally, the conical soil-inserting block 27 at the bottom of the positioning rod 22 first inserts into the soil. At the same time, after the arc-shaped positioning rod 28 abuts against the soil, it slides upward along the positioning rod 22. And when the bottom end of the positioning rod 22 is taken out of the soil, due to the elastic thrust of the return spring 25, the telescopic sleeve block 24 will drive a pair of arc-shaped positioning rods 28 to abut against the conical soil-inserting block 27 at the bottom of the positioning rod 22 again. Then, the conical soil-inserting blocks 27 at the bottoms of the stirring straight rod 26 and the stirring bent rod 29 are inserted into the soil at the same time. Then the motor 15 on the support frame 16 can be started. The output shaft of the motor 15 drives the connecting block 13, the rotating block 12 and the connecting disk 14 to rotate in sequence. The connecting disk 14 drives a plurality of stirring straight rods 26 and stirring bent rods 29 to rotate and stir in the soil, so as to loosen the soil around the small seedling body 3. At the same time, the positioning rod 22 at the bottom of the connecting disk 14 rotates in the connecting disk 14 through a pair of clamping blocks 21 on the rotating shaft 2, so that the arc-shaped positioning rod 28 at the bottom of the positioning rod 22 does not rotate, avoiding damaging the small seedling body 3 after the arc-shaped positioning rod 28 rotates.

[0027] The specific embodiments of the utility model have been described in detail above, but it is only an example, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, equal transformations, modifications, improvements, etc. made without departing from the spirit and principle of the utility model should all be covered within the scope of the utility model.
