Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural weeding technical field especially relates to a prevent the agricultural weeding machine of weed splashing. BACKGROUND

[0002] When crops grow, many weeds will be derived around, if this kind of weed is not removed in time, it will cause great influence to the growth environment of crops, and the nutrient resources of crops will not be guaranteed, therefore people will use weeding machine to process weeds.

[0003] A common agricultural weeding machine that prevents weeds from splashing can only block splashing weeds, but lacks a blocking function. During the cutting process of the blade on weeds, there may be stones or other objects with high hardness on the ground. When the blade collides with such objects, it may cause the blade body to break, ultimately reducing the service life of the blade and the efficiency of weeding.

[0004] Therefore, to solve the problem of lack of blocking function when the blade collides with hard objects during cutting, which may cause the blade body to break, reducing the service life of the blade and the efficiency of weeding, an agricultural weeding machine that prevents weeds from splashing can be designed. SUMMARY

[0005] To overcome the problem of lack of blocking function when the blade collides with hard objects during cutting, which may cause the blade body to break, reducing the service life of the blade and the efficiency of weeding.

[0006] In vast fields, the growth of crops always faces a stubborn opponent - weeds. These seemingly insignificant plants, like "predators" on the growth path of crops, silently erode the survival space of crops. If not removed in time, it will cause immeasurable loss to agricultural production. The emergence of weeding machines provides an efficient and sustainable solution to this ongoing "man and grass war" and has become an indispensable tool in modern agricultural production.

[0007] The harm caused by weeds to crops is multi-dimensional and profound, permeating every stage of crop growth. First, in terms of resource competition, there is fierce competition between weeds and crops. Soil water, nutrients (such as basic elements like nitrogen, phosphorus, and potassium, as well as micronutrients like calcium, magnesium, and sulfur), light, and space are all focal points of competition. Taking water as an example, a vigorous weed can transpire several times the amount of water consumed by a crop every day. This competition is particularly brutal during the dry season. When weed density is high, the water absorbed by crop roots will be greatly reduced, leading to wilting leaves, stunted growth, and in severe cases, even death due to dehydration. The competition for nutrients is equally deadly. Many weeds have well-developed root systems that can quickly absorb nutrients from the soil. For example, the root system of barnyard grass is distributed in a network in the soil, and its nutrient absorption efficiency is far greater than that of rice. If barnyard grass proliferates in rice paddies, rice leaves will turn yellow due to nitrogen deficiency, and tillering will decrease due to phosphorus deficiency, ultimately leading to a sharp drop in yield.

[0008] Secondly, weeds disrupt the ecological balance of the field, providing a breeding ground for pests and diseases. Many weeds are intermediate hosts or overwintering sites for pests and diseases. For example, wheatgrass is an overwintering host for wheat aphids, and shepherd's purse can breed downy mildew. When weeds are abundant, pests and pathogens have a vehicle for reproduction and spread. They can transfer from weeds to crops, causing large-scale pest and disease outbreaks. At the same time, the dense growth of weeds leads to poor ventilation and increased humidity in the field. This environment is conducive to the growth and spread of pathogens such as fungi and bacteria. For example, when there is too much jointed goatgrass in wheat fields, it can easily cause powdery mildew and rust, further aggravating crop losses.

[0009] Furthermore, the presence of weeds can affect the growth, development, and quality of crops. Some tall weeds (such as lambsquarters and amaranth) can block sunlight, weakening photosynthesis in crops due to insufficient light, resulting in weak plants, reduced tillering, and lower seed setting rate. For some cash crops, the presence of weeds can also affect product quality. For example, cocklebur in cotton fields can compete with cotton for nutrients, causing cotton fibers to become shorter and less strong. If weeds in vegetable fields are not removed in time, they can cause vegetable leaves to turn yellow, have a poor taste, and reduce their commercial value. In addition, some weeds can secrete allelochemicals that inhibit crop growth. For example, the chemicals secreted by fleabane can inhibit the germination of seeds and the growth of seedlings in crops such as wheat and corn. This kind of "chemical warfare" is more insidious and persistent in its harm to crops.

[0010] Faced with the numerous harms caused by weeds, traditional weeding methods have obvious limitations. Although manual weeding is precise, it is extremely inefficient and difficult to promote in large-scale farmland. Moreover, it is labor-intensive and costly. With the transfer of rural labor, manual weeding can no longer meet the needs of modern agriculture. Chemical weeding (using herbicides) has played an important role in agricultural production. It is efficient and low-cost, but long-term use will bring a series of problems: herbicide residues will pollute the soil and water sources, harming the ecological environment and human health; long-term use of a single herbicide will lead to herbicide resistance in weeds, making weeding effect worse and worse, and it will be necessary to increase the dosage or use more toxic herbicides, forming a vicious cycle; at the same time, while killing weeds, herbicides may also harm crops and beneficial organisms in the field (such as bees, earthworms, etc.), disrupting the ecological balance.

[0011] Against this backdrop, weeders have gradually become the mainstream tool for weed control due to their advantages of high efficiency, environmental protection, and sustainability. Modern weeders come in a wide variety of types and can adapt to different crop types, planting patterns, and field environments to meet diverse weed control needs.

[0012] Based on their power source, weeders can be divided into manual weeders, motorized weeders, and electric weeders. Manual weeders (such as weed shovels and rakes) are suitable for small vegetable gardens and flower nurseries. They are simple to operate and have low costs, but the labor intensity is still relatively high. Motorized weeders (powered by gasoline or diesel engines) have high power and efficiency and are suitable for large areas of farmland. Examples include self-propelled lawnmowers and backpack weeders, which can quickly remove weeds from the field. Electric weeders (including AC and DC driven ones) are characterized by low noise and low pollution and are suitable for areas with high environmental requirements (such as greenhouses and organic farms). With the development of battery technology, the range of electric weeders is constantly improving, and their application scope is becoming wider and wider.

[0013] Based on their working principle, weeders can be mainly classified into rotary weeders, reciprocating weeders, roller cutters, and flame weeders. Rotary weeders use high-speed rotating blades to cut weeds and are suitable for clearing tall weeds and shrubs. They come in various blade types (such as disc cutters and swivel cutters) and can be selected according to the type and density of weeds. Reciprocating weeders use the reciprocating motion of blades to cut weeds, resulting in a clean cut. They are suitable for lawns, wheat fields, and other places where high weed control is required. Roll cutters use blades on a roller to crush and cut weeds. They are suitable for clearing low-lying weeds and cause less disturbance to the soil. Flame weeders use high-temperature flames to burn weeds. They are suitable for non-arable land, field ridges, and some crop fields sensitive to chemical weeding (such as organic vegetable fields). They are effective at weeding and do not produce chemical residues. However, fire prevention measures must be taken during use to avoid scorching crops.

[0014] With the development of agricultural modernization and intelligentization, new types of weeding machines are constantly emerging, further improving the accuracy and efficiency of weeding. Intelligent weeding machines combine advanced technologies such as GPS positioning, machine vision, and sensors to identify crops and weeds, achieving precise weeding. For example, some intelligent weeding robots can capture field images through cameras, use artificial intelligence algorithms to distinguish between crops and weeds, and then precisely remove weeds through robotic arms or high-pressure nozzles, avoiding damage to crops. This precise weeding not only improves the weeding effect but also reduces energy consumption and soil disturbance, which is in line with the development concept of sustainable agriculture.

[0015] In various agricultural settings, weeders play an irreplaceable role. In large-scale grain crop fields (such as wheat, corn, and rice fields), large self-propelled weeders can complete weeding operations on multiple rows at once, covering dozens of acres per day, significantly improving weeding efficiency and reducing labor costs. In orchards and tea gardens, tracked weeders can adapt to complex terrain and work flexibly between rows of fruit trees or tea trees, removing weeds without damaging the root system of the fruit trees. In greenhouses and vegetable bases, small electric weeders and intelligent weeding robots can operate precisely in confined spaces, meeting the strict requirements of organic farming for weeding methods.

[0016] The widespread use of weeding machines has not only effectively controlled weed damage and ensured the normal growth, yield, and quality of crops, but also promoted the transformation of agricultural production methods. It has reduced dependence on chemical herbicides, lowered pesticide residues and environmental pollution, and is conducive to the development of green and organic agriculture, improving the safety and market competitiveness of agricultural products. At the same time, the use of weeding machines has freed up labor, improved agricultural production efficiency, promoted large-scale and intensive agricultural operations, and provided strong support for the sustainable development of modern agriculture.

[0017] In the future, with the continuous advancement of technology, weeding machines will develop towards greater intelligence, precision, and multi-functionality. For example, by combining big data and IoT technologies, weeding machines can formulate personalized weeding plans based on the distribution of weeds in the field, achieving dynamic weeding. Weeding machines utilizing new energy technologies (such as solar and hydrogen energy) will be more environmentally friendly and energy-efficient. Multi-functional weeding machines (integrating weeding, fertilization, and sowing functions) will further improve the overall efficiency of agricultural production. These innovations will make weed control more efficient, environmentally friendly, and economical, making a greater contribution to ensuring global food security and sustainable ecological development.

Multiple protective bars are fixedly connected to the bottom of the sliding plate. A limit baffle is provided on the top of the front mounting shell. A positioning mechanism is provided on the front mounting shell to fix the position of the protective bars. A weeding mechanism is provided on the splash-proof shell to cut the weeds on the ground.

Then, the movable baffle is rotated to cover the limiting baffle, thereby pressing and fixing the limiting baffle through the movable baffle. When the weeder moves forward, the two rows of misaligned protective guards can block oncoming stones or other high-hardness objects. At the same time, weeds can still pass through the gaps between the multiple protective guards and contact the weed cutter. This achieves the function of blocking hard objects while allowing weeds to pass through.

[0027] The beneficial effects of this utility model are:

[0028] The advantage of this structure is that the misaligned design of the protective baffle can effectively prevent high-hardness objects such as stones from entering the weed cutter, effectively protecting components such as the weed cutter from damage. At the same time, weeds can smoothly contact the weed cutter through the gap of the baffle, ensuring that the weeding process is not hindered. Furthermore, the fixing mechanism of the limiting baffle and the movable baffle enhances the stability and reliability of the overall structure. Attached Figure Description

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] Please see Figures 1-9 This utility model provides an embodiment of an agricultural weeder that prevents weeds from splashing, including a splash-proof housing 1; it also includes a sliding plate 15 and protective bars 16. A front mounting housing 11 is fixedly connected to the front side of the splash-proof housing 1, and a rear storage housing 12 is fixedly connected to the rear side of the splash-proof housing 1. Rollers 13 are rotatably connected to the left and right sides of both the front mounting housing 11 and the rear storage housing 12. Two sliding grooves 14 are formed on the top of the front mounting housing 11, and a sliding plate 15 is slidably connected inside the sliding grooves 14. Multiple protective bars 16 are fixedly connected to the bottom of the sliding plate 15. A limit baffle 17 is provided on the top of the front mounting housing 11. A positioning mechanism is provided on the front mounting housing 11 to fix the position of the protective bars 16. A weeding mechanism is provided on the splash-proof housing 1 to cut weeds on the ground. The storage housing 12 is equipped with a discharge assembly, which is used to unload the weeds stored in the rear storage housing 12. By pushing the two sliding plates 15 in the two sliding grooves 14, the two sliding plates 15 drive the two rows of protective baffles 16 to move to a staggered state. Then, the limiting baffle 17 is placed on the top of the front mounting housing 11. At the same time, the positioning block 212 at the bottom of the limiting baffle 17 is inserted into the positioning hole 211. Then, the movable baffle 222 is rotated to be located on top of the limiting baffle 17. The movable baffle 222 presses down the limiting baffle 17. When the weed cutter moves forward, it will block the stones or other objects with high hardness by using the staggered two rows of protective baffles 16. However, weeds can still pass through the gaps between the multiple protective baffles 16 and come into contact with the weed cutter 323, thus achieving the function of blocking objects.

[0041] Please see Figures 2-9In this embodiment, the positioning mechanism includes a locking component and a pressing component. The locking component is used to limit the position of the sliding plate 15, and the pressing component is used to limit the position of the limiting baffle 17. The locking component and the pressing component are combined to form a complete positioning mechanism. The two cooperate with each other to fix the position of the protective baffle 16. The locking component includes multiple positioning holes 211 opened on the top of the sliding plate 15 and multiple positioning blocks 212 fixed on the bottom of the limiting baffle 17. The positioning blocks 212 are inserted into the interior of the positioning holes 211. The position of the sliding plate 15 inside the sliding groove 14 is fixed by the positioning blocks 212 inserted into the interior of the positioning holes 211. The pressing component includes a handle 221 fixed on the front side of the limiting baffle 17 and two movable baffles 222 rotatably connected to the top of the front mounting housing 11. The movable baffles 222 are located on the top of the limiting baffle 17. By rotating the movable baffles 222, they are pressed against the top of the limiting baffle 17, so that the position of the limiting baffle 17 will not shift.

[0042] Please see Figures 1-9 In this embodiment, the weeding mechanism includes a power supply component and a cutting component. The power supply component supplies power to the weeder, and the cutting component cuts the weeds on the ground. The power supply component and the cutting component are combined to form a complete weeding mechanism, which works together to cut the weeds on the ground. The power supply component includes a battery 311 fixed to the top of the splash-proof housing 1 and a protective cover 312 fixed to the top of the splash-proof housing 1. The battery 311 supplies power to the motor 321, and the protective cover 312 seals the battery 311 and the motor 321, thereby providing protection. The cutting component includes a motor 321 fixed to the top of the splash-proof housing 1 and a cutting component fixed to the output of the motor 321. The drive shaft 322 at the end and two grass-cutting blades 323 fixed on the outside of the drive shaft 322 are connected by a motor 321 to control the rotation of the drive shaft 322. The drive shaft 322 rotates by the motor 321, and the grass-cutting blades 323 rotate by the rotating grass-cutting blades 323. The unloading assembly includes a handle 411 fixed on the top of the rear storage housing 12 and an unloading door 412 movably connected to the rear side of the rear storage housing 12. The cut grass will move into the rear storage housing 12 through the splash guard 1 and be stored inside the rear storage housing 12. When it is necessary to take it out, the unloading door 412 can be opened to take out the grass inside the rear storage housing 12.

[0043] During operation, firstly, push the two sliding plates 15 within the two sliding grooves 14, causing the sliding plates 15 to move the two rows of protective bars 16 to a misaligned position. Then, close the limiting baffle 17 on top of the front mounting housing 11. During this process, the positioning block 212 at the bottom of the limiting baffle 17 is inserted into the positioning hole 211. Then, rotate the movable baffle 222 to cover the limiting baffle 17, thereby pressing and fixing the limiting baffle 17 through the movable baffle 222. Subsequently, start the motor 321, which drives the drive shaft 322 to rotate, and the drive shaft 322 carries... The moving blade 323 rotates, and the weeder is moved by the handle 411. When the weeder moves forward, the two rows of staggered protective bars 16 can block stones or other high-hardness objects coming from the front. At the same time, weeds pass through the gaps between the multiple protective bars 16 and come into contact with the blade 323. The rotating blade 323 cuts the weeds on the ground. The cut weeds move through the splash guard 1 into the rear storage shell 12 and are stored inside the rear storage shell 12. When it is necessary to remove the weeds, the discharge door 412 can be opened to remove the weeds from the rear storage shell 12.

[0044] Through the above steps, by pushing the two sliding plates 15 in the sliding groove 14, the two rows of protective baffles 16 are moved to a misaligned position. Then, the limiting baffle 17 is covered and placed on top of the front mounting housing 11. At the same time, the positioning block 212 at its bottom is inserted into the positioning hole 211. Then, the movable baffle 222 is rotated to cover and press the limiting baffle 17. When the weeder moves forward, the misaligned protective baffles 16 block hard objects such as stones, while weeds can pass through the gaps and contact the weed cutter 323, thus achieving the function of blocking hard objects and allowing weeds to pass through. This solves the problem of a common type of agricultural weeder that can only block flying weeds but lacks the function of blocking objects. When the blade collides with hard objects during cutting, it will cause the blade to break, affecting the blade's service life and weeding efficiency.
