Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, and in particular to a weeding machine for agricultural planting. Background Technology
[0002] Agricultural planting refers to the production activities of human beings in cultivating and managing various crops, utilizing natural resources such as land, water, and climate, and employing techniques such as cultivation, sowing, fertilization, irrigation, and pest and disease control to achieve crop growth and development and obtain harvests. It is the core component of agricultural production, providing human beings with food, industrial raw materials, and basic materials, and is also a fundamental industry for maintaining social and economic development and human survival.
[0003] Agricultural weeders are mechanical equipment specifically designed for agricultural planting scenarios. They remove weeds from fields by cutting, crushing, pulling, or turning over the soil to reduce their competition with crops for nutrients, water, and sunlight. This also lowers the cost of manual weeding and improves efficiency. Common types include handheld, self-propelled, and mounted models, adaptable to different crop planting patterns and field conditions. They are essential tools for ensuring normal crop growth in modern agriculture. However, most of these machines rely on flat terrain and struggle to operate in hilly, mountainous, or terraced fields, sometimes even tilting due to the slope. The angle of the blade, whether it penetrates the soil too deeply or too shallowly, affects the weeding effect. In existing technologies, the blade and the machine body are connected flexibly, such as by spring buffers or hydraulic telescopic rods. When the machine is working on undulating terrain, the blade can automatically rise and fall with the ground height, avoiding missed weeds due to the blade penetrating too deeply or sinking into the soil. However, mechanical weeding has limited effectiveness against perennial weeds. The underground rhizomes of these weeds are deeply embedded in the soil. Mechanical weeding can only cut off the above-ground parts, and the underground rhizomes will quickly sprout new plants. Repeated operations are required to gradually weaken their vitality, reducing work efficiency. Utility Model Content

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an agricultural weeding machine, comprising a body 1, a spraying mechanism 3 installed at the bottom right side of the body 1 for spraying herbicides, a telescopic mechanism 2 fixedly connected to the top right side of the body 1 for adjusting the distance of the body 1, and a pesticide tank 308 fixedly connected to the bottom right side of the body 1. A motor 301 is installed at the bottom of the pesticide tank 308, and a drive gear 302 is fixedly connected to the output end of the motor 301, providing power to subsequent processes. Fixed short rods 306 are fixedly connected to the left and right ends of the bottom of the pesticide tank 308, and racks 305 are slidably connected to the outer sides of the fixed short rods 306. The outer side of the racks 305 meshes with the outer side of the motor 301. A square groove 309 is formed in the middle of the racks 305. Spray pipes 303 are connected to the left and right sides of the bottom of the 08. Fixed square plates 304 are fixedly connected to the opposite sides of the two racks 305. The middle part of the fixed square plate 304 is fixedly connected to the outer side of the spray pipe 303. A stirring assembly 307 is installed on the top of the drive gear 302. The stirring assembly 307 includes a rotating rod 3071, which is fixedly connected to the top of the drive gear 302. A drive bevel gear 3072 is fixedly connected to the top of the rotating rod 3071. A fixed straight plate 3073 is fixedly connected to the middle of the inner side of the medicine tank 308. A driven bevel gear 3074 is rotatably connected to the bottom of the fixed straight plate 3073. The bottom of the driven bevel gear 3074 meshes with the top of the drive bevel gear 3072. A stirring rod 3075 is fixedly connected to the middle of the driven bevel gear 3074. The installation of the stirring rod 3075 facilitates the mixing of the medicine.
[0032] Specifically, after starting the motor 301, the output end of the motor 301 drives the drive gear 302 to rotate. The drive gear 302 meshes with the rack 305, causing the rack 305 to slide outside the fixed short rod 306. The movement of the rack 305 causes the fixed square plate 304 to shift, thereby adjusting the position of the spray pipe 303 and changing the spraying direction of the herbicide. At the same time, the rotating rod 3071 at the top of the drive gear 302 rotates with it, and the drive bevel gear 3072 at the top of the rotating rod 3071 also rotates. Since the drive bevel gear 3072 meshes with the driven bevel gear 3074, it drives the stirring rod 3075 in the middle to rotate, which fully stirs the herbicide in the pesticide tank 308 to ensure that the pesticide is evenly mixed. The stirred herbicide is then evenly sprayed out through the spray pipe 303.
[0033] Reference Figure 1 , Figure 3 and Figure 5The telescopic mechanism 2 includes two sliding rods 201, which are fixedly connected to the top right side of the body 1. A connecting bent rod 202 is slidably connected to the top of each sliding rod 201. A rotating round rod 203 is rotatably connected to the middle of the top of the connecting bent rod 202. A first connecting plate 204 is fixedly connected to the bottom left side of the rotating round rod 203. A second connecting plate 206 is rotatably connected to the bottom of the first connecting plate 204. A connecting rod 205 is fixedly connected to the top of the second connecting plate 206. The outer side of the connecting rod 205 is rotatably connected to the top of the second connecting plate 206. A fixed round rod 207 is fixedly connected to the bottom of the second connecting plate 206. The outer side of the fixed round rod 207 is fixedly connected to the middle part of the sliding rod 201. A drive assembly 208 is installed on the front side of the rotating round rod 203. The drive assembly 208 includes a rotating short column 2081, which is fixedly connected to the front side of the rotating round rod 203. A turntable 2082 is fixedly connected to the outer side of the rotating short column 2081. A limit rod 4 is provided at the top front side of the machine body 1. The rear side of the limit rod 4 is fixedly connected to the front side of the rotating round rod 203. An anti-slip sleeve 5 is provided at the top right side of the machine body 1. The inner side of the anti-slip sleeve 5 is fixedly connected to the outer side of the connecting bent rod 202. The installation of the anti-slip sleeve 5 prevents the user from dropping the device when using it.
[0034] Specifically, the turntable 2082 drives the rotating short column 2081 to rotate, which in turn drives the rotating round rod 203 to rotate. The rotation of the rotating round rod 203 causes the first connecting plate 204 to rotate to the left. The first connecting plate 204 then drives the second connecting plate 206 to rotate. Through the installation of the connecting rod 205, the two first connecting plates 204 and the second connecting plate 206 can rotate synchronously, thereby pushing the sliding rod 201 to slide smoothly on the top of the connecting curved rod 202, achieving the effect of telescopic adjustment to meet the needs of users of different heights.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A liquid inlet pipe 7 is provided in the middle right side of the machine body 1. The bottom of the liquid inlet pipe 7 is connected to the top of the medicine tank 308. A circular cover 8 is provided on the top of the liquid inlet pipe 7. Multiple moving wheels 9 are installed at equal intervals on the bottom of the machine body 1. A fixing block 6 is fixedly connected to the top right side of the machine body 1.
[0036] Specifically, the installation of the circular cover 8 prevents a large amount of dirt from entering from here, and the installation of the casters 9 facilitates the movement of this device.
[0037] Working principle: After the motor 301 is started, the output end of the motor 301 drives the drive gear 302 to rotate. The drive gear 302 meshes with the rack 305, causing the rack 305 to slide on the outside of the fixed short rod 306. The rack 305 drives the fixed square plate 304 to move, which in turn drives the spray pipe 303 to adjust its position, thereby changing the spraying position of the herbicide. At the same time, the rotating rod 3071 at the top of the drive gear 302 rotates with it, and the drive bevel gear 3072 at the top of the rotating rod 3071 also rotates. Since the drive bevel gear 3072 meshes with the driven bevel gear 3074, it drives the stirring rod 3075 in the middle to rotate, stirring the herbicide in the pesticide tank 308 to ensure that the pesticide is uniform. The stirred herbicide is sprayed out through the spray pipe 303.
[0038] Turntable 2082 drives rotating short column 2081 to rotate, and rotating short column 2081 simultaneously drives rotating round rod 203 to rotate. Rotation of round rod 203 causes first connecting plate 204 to rotate to the left. First connecting plate 204 drives second connecting plate 206 to rotate. Through the installation of connecting rod 205, the two first connecting plates 204 and second connecting plate 206 can rotate synchronously, causing sliding rod 201 to slide on top of connecting bent rod 202, thereby realizing telescopic adjustment to accommodate users of different heights.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
