Description

Technical Field

[0001] This utility model relates to a weeding and soil loosening device for tobacco fields, belonging to the field of agricultural machinery technology. Background Technology

[0002] After tobacco seedlings are transplanted, weeding and loosening the soil in the tobacco field are crucial agronomic steps to ensure the normal growth of the tobacco plants. Existing literature (CN 211531858 U) discloses a portable wheeled micro-tiller, including a wheeled chassis, a power system, and rotary tillage blades. The rotary tillage blades include a mounting disc with weeding blades and loosening blades spaced apart on its outer periphery. The weeding blades have a weeding edge on one side of their rotation direction, and the loosening blades have a loosening edge on the other side. The bottom of the loosening blades has several cutting teeth. This device directly connects the rotary tillage blades to the power system. With the blades rotating at high speed, the weeding blades can efficiently cut through tough weeds, while the loosening blades can chop up cut weeds, stubble, small tree roots, and bamboo shoots. The high-speed rotation of the cutting teeth ensures sufficient soil loosening depth. However, this device has a relatively small area for loosening and weeding, making it unsuitable for use in tobacco fields, especially in furrows. Utility Model Content

[0003] Based on the above, this utility model provides a tobacco field weeding and soil loosening device to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a device for weeding and loosening soil in tobacco fields, comprising:

[0005] A wheeled unit includes a frame, wheels, and handles. The wheels are rotatably mounted on both sides of the frame, and the handles are mounted on the rear of the frame.

[0006] The grass-twirling unit includes a power system, a rotating shaft, mounting discs, a main blade, and a secondary blade. The power system is mounted on the frame, and the rotating shaft is connected to the power system. At least two mounting discs are mounted on the rotating shaft at intervals. The main blades are circumferentially spaced between two adjacent mounting discs, and the secondary blades are disposed on the outer end face of the main blades.

[0007] In one example, the power system includes a gasoline engine, a first drive rod, a first power steering gear set, a second drive rod, and a second power steering gear set. The first and second drive rods are respectively disposed on both sides of the frame. The output end of the first drive rod is connected to the first power steering gear set, and the output end of the second drive rod is connected to the second power steering gear set. The rotating shaft is installed between the first and second power steering gear sets, and the top of the first drive rod extends upward above the frame and connects to the output end of the gasoline engine.

[0008] In one example, there are four mounting discs, with the ones at both ends of the rotating shaft being triangular and the one in the middle of the rotating shaft being pentagonal. The main blade is U-shaped and installed between the corners of two adjacent mounting discs.

[0009] In one example, each main blade has multiple secondary blades arranged at a predetermined angle on the main blade, with adjacent secondary blades having opposite angles.

[0010] In one example, each of the main blades has three secondary blades, with the first and third secondary blades arranged at 45° on the main blade and the second secondary blade arranged at 135° on the main blade.

[0011] The beneficial effects of this utility model are as follows: When in operation, the device is placed in the furrow of the tobacco field and driven forward by the power system. On the one hand, the rolling structure composed of the rotating shaft, mounting plate, main blade and auxiliary blade can improve the efficiency of weeding and loosening the soil. On the other hand, during the movement, the main blade and auxiliary blade cut into the soil, which plays a role in quickly weeding and loosening the soil, so that the weeds in the tobacco field are thoroughly cleared and the compacted soil is loosened in time, which is conducive to the rapid development of the tobacco plant roots, promotes the rapid growth of the whole tobacco plant and improves the yield and quality of tobacco leaves.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 5 This embodiment provides a tobacco field weeding and soil loosening device, which includes a wheel unit and a grass-rotating unit.

[0022] The wheeled unit includes a frame 11, wheels 12, and handles 13. The two wheels 12 are rotatably mounted on both sides of the frame 11, and the handles 13 are mounted on the rear of the frame 11. The movement of the frame 11 can be controlled by the handles 13.

[0023] The grass-twirling unit includes a power system 21, a rotating shaft 22, mounting discs 23, main blades 24, and secondary blades 25. The power system 21 is mounted on the frame 11. The rotating shaft 22 is connected to the power system 21 and is located below the frame 11. Multiple mounting discs 23 are spaced apart on the rotating shaft 22. Main blades 24 are spaced apart circumferentially between two adjacent mounting discs 23. The secondary blades 25 are mounted on the outer end face of the main blades 24.

[0024] During operation, the device is placed in the furrow of the tobacco field and driven forward by the power system 21. On the one hand, the rolling structure composed of the rotating shaft 22, mounting plate 23, main blade 24 and auxiliary blade 25 can improve the efficiency of weeding and loosening the soil. On the other hand, during the movement, the main blade 24 and auxiliary blade 25 cut into the soil, which can quickly remove weeds and loosen the soil, so that the weeds in the tobacco field are thoroughly cleared and the compacted soil is loosened in time, which is conducive to the rapid development of the tobacco plant roots, promotes the rapid growth of the whole tobacco plant and improves the yield and quality of tobacco leaves.

[0025] For ease of operation, the power system 21 includes a gasoline engine 211, a first transmission rod 212, a first power steering gear set 213, a second transmission rod 214, and a second power steering gear set 215. The gasoline engine 211 can be a two-stroke gasoline engine. The first transmission rod 212 and the second transmission rod 214 are respectively installed on both sides of the frame 11. The output end of the first transmission rod 212 is connected to the first power steering gear set 213, and the output end of the second transmission rod 214 is connected to the second power steering gear set 215. The rotating shaft 22 is installed between the first power steering gear set 213 and the second power steering gear set 215. The top of the first transmission rod 212 extends upward above the frame 11 and connects to the output end of the gasoline engine 211. The top of the second transmission rod 214 is connected to the support 216 at the bottom of the frame 11. The second transmission rod 214 mainly serves as a support, and its structure is the same as that of the first transmission rod 212. The purpose is to ensure that the rotating shaft 22 and other components are subjected to uniform force on both sides.

[0026] For ease of operation, four mounting discs 23 are used. The two ends of the central rotating shaft 22 are triangular, while the one in the middle is pentagonal. The main blade 24 is U-shaped and installed between the corners of two adjacent mounting discs 23. The triangular and pentagonal mounting discs 23 ensure that the main blade 24 cuts into the soil surface when the device moves forward. It should be noted that the length of the rotating shaft 22 matches the width of the tobacco furrows to achieve thorough weeding and loosening of the soil in one operation.

[0027] To improve efficiency, each main blade 24 has three secondary blades 25. The first and third secondary blades 25 are welded to the main blade 24 at a 45° angle, while the second secondary blade 25 is welded to the main blade 24 at a 135° angle. Tests have shown that this arrangement of the secondary blades 25 on the main blade 24, compared to a single-sided arrangement, can to some extent prevent soil from concentrating and rotating to one side, thus keeping the soil largely in place.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
