Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, in particular to a weeding device for tobacco planting. Background Art

[0002] Tobacco is an annual or limited perennial herb of the Solanaceae family, belonging to the family of tubulose flowers. In addition to being made into cigarettes, dry tobacco, pipe tobacco, cigars, etc. for human consumption, tobacco also has a variety of medical uses. When growing tobacco, it is necessary to deal with weeds in the field.

[0003] Most of the existing weeding devices for tobacco planting are hand-push type, and the weeding knives are mostly arranged in parallel. The weeds are removed by pushing the weeding knives in parallel. However, in current tobacco planting, most of the land is ridged and then planted on the ridges, and a film is covered on the ridges. Therefore, weeds generally do not grow on the top surface of the ridges, and weeds mostly grow on both sides of the ridges. At this time, because the two sides of the ridges are inclined, it is difficult for the existing parallel weeding knives to remove the weeds on both sides of the ridges.

[0004] For example, the existing Chinese announcement number is: CN215379932U, a weeding device for tobacco planting, including a chassis, a transmission box is fixedly installed on one side of the chassis, an output shaft is installed inside the transmission box, and knife discs are installed on both ends of the output shaft passing through the transmission box; windows are opened on both sides of the chassis, and lifting mechanisms are fixedly installed inside the windows.

[0005] It can be seen that the patent document cited above also has the same problem. When the device is in use, the device is pushed and the two blade discs are driven to move to remove weeds. Although the height of the blade disc can be adjusted, the angle of the blade disc cannot be adjusted. Therefore, it can only remove weeds on parallel land, and it is difficult to remove weeds on the side walls of the ridges. Utility Model Content

[0006] The utility model aims to provide a weeding device for tobacco planting to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a weeding device for tobacco planting, comprising a box for installing the tobacco planting weeding device, the outer walls of both sides of the box are symmetrically fixedly connected with L-shaped rods, and the two L-shaped rods are rotatably connected with walking wheels in front, and the two walking wheels hold up the box, and the top surface of the box is fixedly connected with a connecting rod, and the side walls of the connecting rod are symmetrically fixedly connected with handles, and a dual-axis motor is fixedly installed inside the box, and a protective plate is symmetrically hinged on the side walls of the box, and a roller is rotatably connected to the inner side wall of the protective plate and the side wall of the box, and a rotating shaft is fixedly connected to the inside of the roller, and a weeding knife is fixedly connected to the side walls of the two rollers.

[0008] Preferably, both sides of the dual-axis motor are rotatably connected with telescopic universal shafts, and one end of the telescopic universal shaft away from the dual-axis motor is rotatably connected to the rotating shaft of the drum.

[0009] Preferably, the side wall of the box body and the top surface of the protective plate are both fixedly connected with fixed blocks, one of the fixed blocks is rotatably connected with a first connecting block, and the end of the first connecting block is fixedly connected with a limiting cylinder.

[0010] Preferably, a telescopic rod is slidably connected in the limiting cylinder, a second connecting block is fixedly connected to the end of the telescopic rod, and a terminal end of the second connecting block is rotatably connected to another fixed block.

[0011] Preferably, a spring is fixedly installed inside the limiting cylinder, and one end of the telescopic rod slidably connected to the inside of the limiting cylinder is fixedly connected to the spring.

[0012] Preferably, the inner wall of the limiting cylinder is symmetrically provided with limiting grooves, the side wall of the telescopic rod is symmetrically fixedly connected with limiting blocks, and the two limiting blocks are slidably connected to the inside of the two limiting grooves respectively.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The tobacco planting weeding device first places the two running wheels below the device between two field ridges. At this time, the two rollers and weeding knives on both sides of the box are hinged to the box because the protective plates are hinged to the box, so that the rollers and weeding knives are tilted and contact the side walls of the field ridges. At this time, the spring inside the limit cylinder pushes the telescopic rod protective plate to move toward the side walls of the field ridges, thereby pushing the two rollers and weeding knives to fit closely on the field ridges, and then starting the dual-axis motor to drive the two rollers and weeding knives to rotate at the same time, so as to remove the weeds on the field ridges. Compared with the prior art, the device can effectively remove the weeds on both sides of the field ridges of tobacco planting. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the device is pushed by the handle 5, so that the weeds on both sides of the ridges can be removed and the soil on both sides of the ridges can be loosened at the same time.
