Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a tobacco gantry-type weeding and soiling integrated machine. Background Art

[0002] In the current tobacco cultivation industry, weeding and soiling operations in tobacco fields mostly rely on traditional manual labor or simple mechanized tools. These traditional methods are inefficient, labor-intensive, and easily damage tobacco plants, affecting yield and quality. Conventional weeding and soiling machinery is particularly difficult to use for tall tobacco plants, such as those exceeding 30 cm in height, resulting in operational difficulties and damage to tobacco leaves.

[0003] Furthermore, while some existing weeding and soiling machines, such as suspended cultivators, can improve operational efficiency to a certain extent, they still present significant challenges when working with tall tobacco plants. Because these machines are primarily designed for contact weeding and soiling, they are prone to friction with tobacco leaves during operation, causing damage to the leaves and, in severe cases, even destroying the plants. Furthermore, these machines often struggle to maintain uniform and consistent working depth, which compromises soiling effectiveness and, in turn, affects tobacco growth and yield.

[0004] To address these challenges, improve the efficiency of weeding and soiling in tobacco fields while protecting tobacco plants and leaves from damage, a new type of gantry-style weeding and soiling machine is needed. This machine requires an elevated design to accommodate tobacco plants of varying heights, while utilizing non-contact weeding and soiling techniques to avoid damaging the leaves. This design maximizes plant and leaf protection while maintaining operational efficiency, ultimately improving tobacco yield and quality. Utility Model Content

[0046] Gantry weeding and soiling machine operation steps;

[0047] (1) Connect the gantry weeding and soiling machine to a power locomotive (such as a tractor) through a suspension system.

[0048] (2) Start the power locomotive to provide power to the machine.

[0049] (3) Adjust the elevated structure to an appropriate height to accommodate the height of the tobacco plants in the tobacco field.

[0050] (4) Turn on the weeding device and start the rotating blade to perform weeding operations.

[0051] (5) Then, the soiling device is turned on, and the depth and width of the soiling shovel on the soiling device 6 are adjusted to carry out soiling operations.

[0052] (6) After the operation is completed, shut down the machine, separate it from the power locomotive, and carry out necessary maintenance and care.

[0053] Other components and connection relationships are the same as those in the first embodiment.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
