Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery and relates to a weeding agricultural machine used for clearing weeds in farmland. Background Art

[0002] In agricultural production, the spacing between crop rows is typically between 10 and 20 centimeters, which provides space for weeds to grow. Weeds not only compete with crops for water, nutrients, and sunlight, but can also serve as intermediate hosts for pests and diseases, damaging crop growth and farmland irrigation facilities.

[0003] Existing weeding machines, such as rotary tillers, can remove some weeds, but they have some disadvantages. For example, they may damage the roots of crops, weeding is incomplete, and repeated operations are required. The operation quality is affected by the performance of the machine and the technical level of the operator. At the same time, they are not suitable for field crops that have already emerged and matured.

[0004] The inventors discovered that existing weeding machine designs fail to adequately consider crop row spacing and weed growth characteristics. For example, the weeding width and depth of a rotary tiller may not be suitable for conventional crop row spacing, resulting in incomplete weeding or crop damage. Furthermore, rotary tillers may leave weed roots in the soil during operation, which can then continue to grow and form new weeds. Summary of the Invention

[0005] In light of this, the present invention aims to provide a novel agricultural weeding machine that, through innovative mechanical design, effectively removes weeds from farmland while minimizing impact on crops and the environment. Primarily suitable for use in fields where crops have already grown, this machine offers greater efficiency than manual weeding and meets the current demands of green and organic production.

[0006] The inventor has made continuous innovations through long-term exploration and attempts, as well as numerous experiments and efforts. To solve the above technical problems, the present invention provides a weeding machine, comprising:

[0007] A traveling mechanism, the traveling mechanism comprising a front mounting frame and a rear axle, the front mounting frame being provided with a front wheel, and the rear axle being provided with a rear wheel;

[0008] A clamping mechanism, wherein the clamping mechanism includes a first conical disk and a second conical disk, the first conical disk and the second conical disk are driven by a first motor and a second motor respectively, the conical surfaces of the two conical disks coincide with a generatrix, and the angle between the coincidence line and the travel direction of the walking mechanism is 45° to 75°;

[0009] The crushing mechanism is located above and behind the clamping mechanism and includes a crushing motor and a cutting line. The cutting line rotates rapidly under the drive of the crushing motor. The rotating surface of the cutting line and the coincidence line are located on the same vertical plane. The minimum distance between the outer edge of the cutting line and the coincidence line is 0.5 to 2 cm.

[0010] Preferably, the first conical disk and the second conical disk are made of hard material or flexible material.

[0011] Preferably, the surfaces of the first conical disk and the second conical disk are configured as anti-slip surfaces.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The design of the first and second conical discs in the clamping mechanism, and the way they are driven by a motor, ensure that weeds can be effectively clamped and uprooted. The conical surfaces of the two conical discs coincide with a main line and are angled at 45° to 75° with the direction of travel of the walking mechanism, making the weeding process more efficient. The crushing mechanism is located at the upper and rear end of the clamping mechanism, allowing weeds to be crushed immediately after being uprooted. This not only improves operational efficiency but also facilitates weed return to the field, increasing soil fertility. Driven by the crushing motor, the cutting line rotates rapidly, lying on the same vertical plane as the coincidence line. The minimum distance between the outer edge of the cutting line and the coincidence line is 0.5 to 2 cm. This design ensures that weeds are evenly and thoroughly crushed.

[0014] Furthermore: the walking mechanism is a walk-behind tractor.

[0015] Preferably, the first conical disk and the second conical disk have a cone bottom diameter of 16 to 18 cm and a cone height of 4.5 to 6 cm.

[0016] On the basis of the above technical solution, the present invention can also be improved as follows:

[0017] Further:

[0018] It also includes a rotary tillage mechanism, which is detachably installed behind the clamping mechanism.

[0019] Preferably, the rotary tillage mechanism is a micro-tillage machine, which is used to loosen the soil and remove weed seedlings.

[0020] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0021] Weeding machines offer greater flexibility to adapt to diverse agricultural needs. When soil cultivation is needed to promote crop growth or prepare for seeding, the rotary tillage mechanism can be installed. When only weeding is required, the mechanism can be removed, reducing the machine's weight and improving efficiency. This design not only enhances the machine's versatility but also helps reduce energy consumption and maintenance costs, thereby improving the economic benefits of agricultural production.

[0022] On the basis of the above technical solution, the present invention can also be improved as follows:

[0023] Further:

[0024] The crushing mechanism also includes a guard plate for shielding the splashing of crushed weed particles.

[0025] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0026] The guard plate improves weeding safety while reducing wear on other machine components caused by weed pellets, extending the machine's service life. Furthermore, the guard plate helps control the distribution of weed pellets, contributing to better field return and promoting the natural replenishment of soil fertility.

[0027] On the basis of the above technical solution, the present invention can also be improved as follows:

[0028] Furthermore: the cutting wire is a flexible steel wire.

[0029] Preferably, there are multiple cutting wires, which are evenly arranged on the outer rotor of the grinding motor.

[0030] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0031] A flexible steel wire is used as the cutting line to efficiently shred weeds within the V-shaped groove formed by the first and second conical discs. This flexible wire has high strength and flexibility, adapting to the irregular shapes and varying hardness of weeds, ensuring thorough shredding after weeds are pulled up and clamped.

[0032] On the basis of the above technical solution, the present invention can also be improved as follows:

[0033] Further:

[0034] It also includes a guide assembly, which is horizontally arranged in front of the clamping mechanism. The guide assembly includes two horizontally arranged guide rods. The front end spacing of the two guide rods is not greater than the crop row spacing, and the rear end spacing of the two guide rods is not less than the front end opening distance of the two conical disks. The guide rods are installed on the front mounting frame through connecting rods.

[0035] Preferably, the height of the guide rod is equal to the height of the cone top of the first conical disk.

[0036] Compared with the prior art, the beneficial effects of adopting the above further technical solution are:

[0037] By adding a guide assembly, weeds are more efficiently and precisely guided into the V-shaped groove between the first and second cones. The design of the guide assembly ensures that weeds are correctly guided and positioned before removal, thereby improving the efficiency and effectiveness of weed removal.

[0062] The following describes a specific embodiment with reference to the accompanying drawings.

[0063] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0064] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0065] See also Figures 1 to 5 The weeding agricultural machine described in this embodiment includes:

[0066] The walking mechanism 100 comprises a front mounting frame 110 and a rear axle 120. The front mounting frame 110 is mounted with a front wheel 111, and the rear axle 120 is mounted with a rear wheel 121. In this embodiment, the walking mechanism 100 is designed as a walk-behind tractor, allowing the operator to control the movement and steering of the agricultural machine using a handle or joystick, enabling flexible field operations. As the mounting base for all equipment, the walking mechanism 100 not only supports components such as the clamping mechanism 200, the crushing mechanism 300, and the rotary tillage mechanism 400, but also provides a mobile platform for these components, enabling the entire weeding machine to operate efficiently in the field. The walk-behind tractor design provides stable movement and steering capabilities, allowing the agricultural machine to maintain stability in farmland of varying terrain. The operator can directly control the movement and steering of the agricultural machine, improving operational flexibility and efficiency. The choice of power source can be adjusted according to actual needs and conditions, such as using an internal combustion engine to adapt to vast farmland or an electric motor to reduce environmental impact.

[0067] The design of the running mechanism 100 is key to the overall performance of a weeding machine, directly impacting its efficiency, stability, and ease of operation. Through careful design, the running mechanism 100 can meet the demands of diverse farmland operations, providing a solid foundation for weeding operations.

[0068] The clamping mechanism 200 includes a first conical disk 210 and a second conical disk 220. The first conical disk 210 and the second conical disk 220 are driven by a first motor 211 and a second motor 221 respectively. The conical surfaces of the two conical disks coincide with a busbar, and the angle between the coincidence line and the travel direction of the walking mechanism 100 is 45° to 75°; the bottom circle diameter of the first conical disk 210 and the second conical disk 220 is 16 to 18 cm, and the height of the cone is 4.5 to 6 cm.

[0069] The first conical disc 210 and the second conical disc 220 are made of hard material or flexible material, and the surface is configured as a non-slip surface to facilitate clamping weeds.

[0070] The clamping mechanism 200 is a key component for weeding in the weeding machine of the present invention. It consists of two conical discs, namely a first conical disc 210 and a second conical disc 220. These two conical discs are driven by independent first motors 211 and second motors 221, respectively, to ensure the accuracy and controllability of the clamping action. Figure 2, the first conical disc 210 and the second conical disc 220 rotate counterclockwise. The design of the conical discs enables them to overlap along a common busbar when working, forming an X-shaped clamping space, including a V-shaped grass inlet and a V-shaped grass outlet. The angle between the overlap line and the travel direction of the walking mechanism 100 is designed to be between 45° and 75°, with a recommended angle of 60°, in order to more effectively capture and remove weeds. The size of the conical disc is a bottom circle diameter of 16 to 18 cm and a cone height of 4.5 to 6 cm. The design of the conical disc ensures sufficient clamping force while avoiding unnecessary damage to crops.

[0071] The two rotating conical disks, under the action of their surface friction, roll weeds of designed height into the X-shaped clamping space. Under the action of the friction between the weeds and the conical disk surfaces, the holding force of the two conical disks and the traction force of the walking mechanism, the weeds are pulled out by the roots.

[0072] The crushing mechanism 300 is located at the upper rear of the clamping mechanism 200 and includes a crushing motor 310 and a cutting line 320. The cutting line 320 rotates rapidly under the driving action of the crushing motor 310. The rotating surface of the cutting line 320 and the coincidence line are located on the same vertical plane. The minimum distance between the outer edge of the cutting line 320 and the coincidence line is 0.5 to 2 cm. The cutting line 320 is a flexible steel wire. There are multiple cutting lines 320, which are evenly arranged on the outer rotor of the crushing motor 310. Looking directly at Figure 2 , the cutting wire 320 rotates counterclockwise around the crushing motor 310.

[0073] The crushing mechanism 300 is one of the core components of the weeding agricultural machine of the present invention. Its design fully considers the coordinated work with the clamping mechanism 200. This mechanism is located at the upper rear of the clamping mechanism 200, ensuring that the weeds can quickly enter the crushing mechanism for processing after being pulled up. The crushing motor 310 preferably uses an outer rotor motor to provide power to the cutting line 320, enabling it to rotate at high speed, thereby effectively chopping the weeds. The rotating surface of the cutting line 320 and the coincidence line are located on the same vertical plane. This design ensures that the weeds can be accurately captured and crushed after being pulled up. In addition, the minimum distance between the outer edge of the cutting line 320 and the coincidence line is controlled between 0.5 and 2 cm, and the recommended distance is 1 cm.

[0074] The beneficial effects of the crushing mechanism 300 are reflected in its efficient crushing ability and protection of the farmland environment. By precisely controlling the distance between the cutting line 320 and the coincidence line, the present invention ensures that the weeds can be evenly and thoroughly crushed and returned to the field, which helps to improve the fertility of the soil while reducing the possibility of weed regeneration. The first conical disc 210 and the second conical disc 220 transport the leaves, stems and roots of the weeds upward, and the cutting line 320 cuts the weeds downward in the V-shaped weed outlet. This design also helps to reduce damage to crops and protect the healthy growth of crops. In general, the design of the crushing mechanism 300 not only improves the efficiency of weeding operations, but also helps to achieve sustainable agricultural development and reduce the impact on the environment.

[0075] The shredder mechanism 300 also includes a shield 330 for shielding the weed shredder from splashing particles. In this embodiment, the shredder motor 310 and shield 330 are fixedly mounted on the front mounting frame 110. The shield 330 comprises left and right side panels, a top panel, and a rear panel. The shield 330's primary function is to effectively shield and control the splashing of particles when the shredder motor 310 drives the cutting wire 320 to shred weeds at high speed, preventing harm to the operator and reducing pollution to the surrounding environment.

[0076] The rotary tillage mechanism 400 is detachably mounted behind the clamping mechanism 200. This design provides additional functionality and flexibility to the weeding machine. As a detachable component, the rotary tillage mechanism 400 can be conveniently installed behind the clamping mechanism 200, enabling the machine to cultivate the soil when needed. This design allows users to choose whether to use the rotary tillage function based on specific farmland conditions and operational requirements, thereby increasing the adaptability and versatility of the machine.

[0077] In some preferred embodiments, the rotary tillage mechanism 400 is a micro-rotary tillage mechanism, the main purpose of which is to loosen the surface soil and remove weed seedlings.

[0078] The addition of the rotary tillage mechanism 400 enables the weeding machine to plow and loosen the soil while completing the weeding operation, which helps to improve the soil structure.

[0079] Example 2

[0080] See also Figure 6 Based on Example 1, this embodiment further includes a guide assembly 230. The guide assembly 230 is horizontally arranged directly in front of the clamping mechanism 200. The guide assembly 230 includes two horizontally arranged guide rods. The distance between the front ends of the two guide rods is no greater than the distance between the crop rows, and the distance between the rear ends of the two guide rods is no less than the distance between the front openings of the two conical disks. The guide rods are mounted on the front mounting frame 110 via connecting rods. The height of the guide rods is equal to the height of the cone top of the first conical disk 210.

[0081] Based on Example 1, this embodiment adds a guide assembly 230. This innovative design significantly improves the operating accuracy and crop protection capabilities of the weeding agricultural machinery. The guide assembly 230 is horizontally arranged directly in front of the clamping mechanism 200 and consists of two horizontal guide rods. The front end spacing of these guide rods is carefully designed to ensure that it is no greater than the row spacing of the crops, so that the agricultural machinery can pass smoothly between the crop rows and minimize interference with the crops. At the same time, the rear end spacing of the guide rods is designed to be no less than the front end opening distance of the two conical disks 210 and 220, ensuring that weeds can be effectively guided between the conical disks, ensuring the efficiency and effectiveness of weeding. The guide rods are mounted on the front mounting frame 110 via a connecting rod. This installation method not only ensures the stability of the guide rods, but also facilitates adjustment and maintenance.

[0082] Common weeds, such as Chickweed (generally 30-80 cm tall), Alopecuroides (up to 40 cm tall), Quinoa (30-150 cm tall), Goosegrass (10-90 cm tall), Bromus (40-90 cm tall), and Aesculus (20-40 cm tall), can be removed using the weeding machine of the present invention. However, it should be noted that the weeding machine of the present invention is not suitable for weeds that are too low in height. The timing of weeding operations should be determined based on the height of the weeds in the field. However, when weeds have just sprouted, they are difficult to remove, whether using a weeder or manually.

[0083] In order to adapt to field row operations, the overall structure of weeding machinery should be miniaturized and micro-miniaturized. Figures 1 to 6 The structural principle of the weeding machine is illustrated. Its specific size can be set according to the type of crop and regional weed characteristics.
