Description

Technical Field

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

[0002] In agricultural production, the spacing between crop rows is usually more than 10 to 20 centimeters, which provides space for the growth of weeds. Weeds not only compete with crops for water, nutrients and light, but may also become intermediate hosts for pests and diseases, causing damage to crop growth and farmland water conservancy 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, repeated operations are required, and 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 situations where field crops have already sprouted and matured.

[0004] The inventors found that the design of existing weeding machines does not fully consider the row spacing of field crops and the growth characteristics of weeds. For example, the weeding width and depth of the rotary tiller may not be suitable for the row spacing of conventional crops, resulting in incomplete weeding or damage to crops. In addition, the rotary tiller may leave the roots of weeds in the soil during operation, and these remaining roots may continue to grow and form new weeds. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a new type of weeding agricultural machine, which can effectively remove weeds in farmland through innovative mechanical design, while reducing the impact on crops and the environment. It is mainly suitable for field environments where crops have grown, has higher efficiency than manual weeding, and is also suitable for the needs of green production and organic production at that time.

[0006] The inventor has continuously innovated and reformed through long-term exploration and attempts, as well as many experiments and efforts. In order to solve the above technical problems, the technical solution provided by the present invention is to provide a weeding agricultural machine, including:

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

[0008] A clamping mechanism, wherein the clamping mechanism comprises 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 traveling 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 driving action 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, 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 cone and the second cone in the clamping mechanism, and the way they are driven by the motor, ensure that the weeds can be effectively clamped and uprooted. The conical surfaces of the two cones coincide with a generatrix, and the angle with the travel direction of the walking mechanism is 45° to 75°. This design makes the weeding process more efficient. The crushing mechanism is set at the upper rear of the clamping mechanism, so that the weeds can be crushed immediately after being uprooted. This not only improves the work efficiency, but also helps to return the weeds to the field and increase soil fertility. The cutting line rotates rapidly under the drive of the crushing motor and is located 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 the weeds can be crushed evenly and thoroughly.

[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 16-18 cm and a cone height of 4.5-6 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 can adapt to different agricultural operation needs more flexibly. When soil cultivation is needed to promote crop growth or prepare for sowing, a rotary tillage mechanism can be installed; when only weeding is needed, the rotary tillage mechanism can be removed to reduce the weight of the machine and improve operation efficiency. This design not only improves the versatility of the machine, 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 pulverizing mechanism also includes a guard plate for shielding the splashing of pulverized weed particles.

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

[0026] The guard plate improves the safety of weeding operations, while reducing the wear of weed crushed particles on other parts of the agricultural machinery, extending the service life of the entire machine. In addition, the guard plate can also help control the distribution of weed crushed particles, help to better achieve the effect of returning to the field, and promote 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 pulverizing motor.

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

[0031] The flexible steel wire is used as the cutting wire to achieve efficient shredding of the weeds in the V-shaped groove formed by the first cone and the second cone. This flexible steel wire has high strength and flexibility, can adapt to the irregular shape and different hardness of the weeds, and ensure that the weeds can be completely shredded after being 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 the guide assembly, the weeds can be more efficiently and accurately guided into the V-shaped groove between the first cone and the second cone. The design of the guide assembly ensures that the weeds can be correctly guided and positioned before being pulled out, thereby improving the efficiency and effect of weeding.

[0062] The following is a description with reference to the accompanying drawings and a specific embodiment.

[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 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 thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

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

[0066] The walking mechanism 100 includes a front mounting frame 110 and a rear axle 120, wherein a front wheel 111 is mounted on the front mounting frame 110, and a rear wheel 121 is mounted on the rear axle 120. In the present embodiment, the walking mechanism 100 is designed as a walk-behind tractor, so that the operator can control the walking and steering of the agricultural machine through a handle or a joystick, thereby realizing flexible field operation. As the installation base of all equipment, the walking mechanism 100 not only supports components such as a clamping mechanism 200, a crushing mechanism 300, and a rotary tillage mechanism 400, but also provides a mobile platform for these components, so that the entire weeding agricultural machine can operate efficiently in the field. The design of the walk-behind tractor provides stable walking and steering capabilities, so that the agricultural machine can remain stable in farmlands of different terrains. The operator can directly control the walking and steering of the agricultural machine, thereby improving the flexibility and efficiency of the operation. The choice of the power source can be adjusted according to actual needs and conditions, such as using an internal combustion engine to adapt to a vast farmland, or using an electric motor to reduce the impact on the environment.

[0067] The design of the walking mechanism 100 is the key to the overall performance of the weeding agricultural machine, which directly affects the operation efficiency, stability and convenience of operation of the agricultural machine. Through careful design, the walking mechanism 100 can meet the needs of different farmland operations and provide 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 generatrix, and the angle between the coincidence line and the traveling 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 cone disk 210 and the second cone disk 220 are made of hard material or flexible material, and the surface is set to be anti-slip surface to facilitate clamping weeds.

[0070] The clamping mechanism 200 is a key component for removing weeds in the weeding agricultural machine of the present invention. It is composed of two cone-shaped discs, namely a first cone-shaped disc 210 and a second cone-shaped disc 220. The two cone-shaped 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 cone disk 210 and the second cone disk 220 rotate counterclockwise. The design of the cone disks enables them to overlap along a common generatrix 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°, and the recommended angle is 60°, so as to more effectively capture and remove weeds. The size of the cone disk is a bottom circle diameter of 16 to 18 cm and a cone height of 4.5 to 6 cm. The design of the cone disk ensures sufficient clamping force while avoiding unnecessary damage to crops.

[0071] The two rotating conical disks, under the action of their surface friction, roll the 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 wire 320. The cutting wire 320 rotates rapidly under the driving action of the crushing motor 310. The rotating surface of the cutting wire 320 and the coincidence line are located on the same vertical plane. The minimum distance between the outer edge of the cutting wire 320 and the coincidence line is 0.5 to 2 cm. The cutting wire 320 is a flexible steel wire. There are multiple cutting wires 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, and its design fully considers the coordinated work with the clamping mechanism 200. The 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 for the cutting line 320, so that it can rotate at a 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 accurately 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 disk 210 and the second conical disk 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 crushing mechanism 300 further includes a guard plate 330 for shielding the splash of crushed weed particles. In this embodiment, the crushing motor 310 and the guard plate 330 are fixedly mounted on the front mounting frame 110, and the guard plate 330 has left and right side plates, a top plate, and a rear side plate. The main function of the guard plate 330 is to effectively shield and control the splash of crushed weed particles when the crushing motor 310 drives the cutting wire 320 to rotate at a high speed to crush the weeds, thereby preventing the splash of crushed weed particles from causing harm to the operator and reducing the pollution to the surrounding environment.

[0076] The rotary tillage mechanism 400 is detachably mounted behind the clamping mechanism 200. The design of the rotary tillage mechanism 400 provides additional functionality and flexibility for the weeding agricultural machine. As a detachable component, the rotary tillage mechanism 400 can be conveniently mounted behind the clamping mechanism 200, so that the agricultural machine can till the soil when needed. This design allows the user to choose whether to use the rotary tillage function according to specific farmland conditions and operation requirements, thereby improving the adaptability and versatility of the agricultural 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 till and loosen the soil while completing the weeding operation, which helps to improve the soil structure.

[0079] Example 2

[0080] See also Figure 6 On the basis of embodiment 1, this embodiment further includes a guide assembly 230, which is horizontally arranged in front of the clamping mechanism 200. The guide assembly 230 includes two horizontally arranged guide rods, the front end spacing of the two guide rods is not greater than the crop row spacing, the rear end spacing of the two guide rods is not less than the front end opening distance of the two cone disks, and the guide rods are installed on the front mounting frame 110 through connecting rods. The height of the guide rods is equal to the cone top height of the first cone disk 210.

[0081] On the basis of Example 1, this embodiment adds a guide assembly 230. This innovative design significantly improves the operating accuracy and crop protection ability of the weeding agricultural machinery. The guide assembly 230 is horizontally arranged in front of the clamping mechanism 200 and is composed of two horizontal guide rods. The front end spacing of these guide rods is carefully designed to ensure that it is not 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 rod is designed to be no less than the front end opening distance of the two conical disks 210 and 220, ensuring that the weeds can be effectively guided between the conical disks, ensuring the efficiency and effect of weeding. The guide rod is installed on the front mounting frame 110 through a connecting rod. This installation method not only ensures the stability of the guide rod, but also facilitates adjustment and maintenance.

[0082] Common weeds, such as: the height of Chickweed is generally between 30 and 80 cm, the height of Alopecurus mume can reach 40 cm, the height of Chenopodium album is 30 to 150 cm, the height of Goosegrass is 10 to 90 cm, the height of Bromus striata is 40 to 90 cm, and the height of Aegilops tauschii is 20 to 40 cm. These weeds can be weeded by the weeding agricultural machine of the present invention. However, it should be pointed out that the weeding agricultural machine of the present invention is not suitable for weeds with too low height. When using it, it is necessary to determine the timing of weeding operation according to the growth height of weeds in the field. However, when the weeds have just sprouted, it is also difficult to pull them out regardless of whether it is a weeder or manual operation.

[0083] In order to adapt to the field row operations, the overall structure of the weeding agricultural 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 the characteristics of regional weeds.
