Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an adjustable agricultural machinery tiller and weeder. Background Technology

[0002] In modern agricultural production systems, weeding and hoeing are crucial for ensuring crop growth and improving yield and quality. By loosening the soil and removing weeds, this operation improves soil aeration and water retention, creating a favorable environment for crop root development. It also reduces competition for nutrients and light between weeds and crops, lowering the risk of pests and diseases. Therefore, it plays an irreplaceable role in achieving high-quality and high-yield crops, including grains, cash crops, and fruits and vegetables.

[0003] Against this backdrop, weeding and tillage, with its characteristics of being free of chemical pollution and primarily relying on physical processes, has become the most environmentally friendly weeding method that meets the requirements of green agriculture. The working principle of a weeding and tillage machine is that a double-winged hoe penetrates deep into the soil as the machine moves forward. As the machine moves, the hoe acts on the soil with a forward cutting and upward tilling trajectory. The blades first cut into the surface layer of the soil (adjusted according to the needs of the crop), cutting and breaking up the compacted soil. At the same time, the curved structure of the hoe turns the broken soil upward, forming a loose topsoil layer, which increases soil permeability and brings nutrients from deeper soil layers to the surface, making it easier for crop roots to absorb.

[0004] However, existing weeding and cultivating machines still have technical shortcomings in practical applications. After weeding, they do not collect the weeds. Because some weeds are highly resilient, if it rains within 1-2 days after cultivation, they easily regrow and re-root in the soil, significantly reducing the effectiveness of weeding and requiring secondary operations, increasing production costs and the work cycle. More importantly, none of the current weeding and cultivating machines are designed with a unified weed collection function. Weeds left after tilling are either left in the field or scattered along the work path, which not only may regrow but also affect subsequent agricultural operations such as sowing and fertilization, contradicting the needs of modern, refined agricultural management. Therefore, we propose an adjustable agricultural machinery weeding and cultivating machine to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable agricultural machinery weeding machine to solve the problems mentioned in the background art. Traditional weeding machines lack weed collection functions, and some resilient weeds are prone to take root and revive after rain, resulting in reduced weeding effect, the need for secondary operations, and increased costs and cycles. Furthermore, weeds remain in the field or are scattered along the path after tilling, which may regrow and affect subsequent agricultural operations, failing to meet the needs of modern agricultural precision management.

[0006] This utility model provides the following technical solution: An adjustable agricultural machinery weeding machine includes a weeding machine frame and multiple weeding mechanisms evenly connected to the weeding machine frame by bolts. The weeding machine frame is fixedly connected to a weed collection box by a vertical frame, and each of the weeding mechanisms is fixedly connected to a weed collection device on the side away from the direction of travel of the weeding machine. The weed collection device consists of a fixed frame, a collection guide, a fixed plate, an angle adjustment component for adjusting the angle of the collection guide, and a weed rake; one end of the fixed frame is detachably connected to the weeding mechanism, and the collection guide is symmetrically arranged on both sides of the fixed frame away from the weeding mechanism.

[0007] Preferably, each of the collecting guide components includes a first fixed seat, a first rotating shaft, a fixed rod, and a hay-raking guide disc; the hay-raking guide disc is rotatably sleeved on the outer wall of one end of the fixed rod, the other end of the fixed rod is rotatably connected to the first fixed seat through the first rotating shaft, and the first fixed seat is welded to the outer wall of the fixed frame.

[0008] Preferably, the fixing plate is fixedly installed on the front outer wall of the fixing frame, and a connecting through hole is provided on the top of the fixing plate on the side away from the fixing frame. The connecting through hole is used to seal and fix the feed end of the external suction conveying pipe. The discharge end of the external suction conveying pipe extends into the internal cavity of the weed collection box, and the discharge end port does not contact the inner wall of the weed collection box.

[0009] Preferably, the angle adjustment component includes a second fixed seat, a second rotating shaft, and an electric telescopic rod; the second fixed seat is welded and fixed to the outer wall of the fixed frame and is located on one side of the first fixed seat; the fixed end of the electric telescopic rod is rotatably connected to the second fixed seat through the second rotating shaft, and the telescopic end of the electric telescopic rod is rotatably connected to the third fixed seat through the third rotating shaft, and the third fixed seat is welded and fixed to the outer wall of the middle part of the fixed rod.

[0010] Preferably, the grass rake is fixedly installed below the end of the fixing plate, and the installation position of the grass rake corresponds to the position of the connecting through hole, so as to ensure that the weeds collected by the grass rake can be guided to the connecting through hole.

[0011] Preferably, the electric telescopic rod is electrically connected to the weeder's built-in power supply via a wire, and a control switch for controlling the start / stop and telescopic range of the electric telescopic rod is connected in series on the wire. This control switch is integrated into the weeder's operation control panel.

[0012] This utility model has the following beneficial effects: 1. The unified weed collection function of this application effectively solves the problem of weed residue affecting subsequent sowing and fertilization caused by traditional weeders. On the one hand, the weeds are collected centrally in the weed collection box, eliminating weed accumulation in the field and allowing for direct subsequent agricultural operations without additional cleaning. On the other hand, the collected weeds can be used as green manure or centrally treated in a harmless manner, achieving resource recycling. This aligns with the modern agricultural management concepts of waste reduction, efficiency improvement, and green ecology, providing equipment support for large-scale, standardized planting.

[0013] 2. The electric telescopic rod design of the angle-adjustable component allows for real-time control of the fixed rod angle of the collection guide, thereby adjusting the working posture of the rake guide disc. Operators can precisely adjust the angle using a switch integrated into the control panel, adapting to various crop planting scenarios without disassembling or replacing parts, thus accommodating different crop row spacings and soil looseness. Simultaneously, angle adjustment prevents the rake guide disc from colliding with crop roots, reducing crop damage and improving operational safety.

[0014] 3. The connecting holes of the fixing plate and the external suction and conveying pipe are sealed and fixed to prevent weeds from falling during the suction process, ensuring collection efficiency. Simultaneously, the rake is positioned to correspond with the connecting holes, achieving a seamless connection between weed collection, guidance, and suction, preventing weeds from scattering during transport. Furthermore, centralized weed collection reduces pesticide use, meeting the requirements of green agriculture with no chemical pollution, reducing ecological damage to soil and water sources, and achieving both economic and environmental benefits.

[0021] 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.

[0022] Please see Figure 1 and Figure 2 As shown, this is an adjustable agricultural tiller and weeder. The tiller and weeder includes a frame 1 and multiple weeding mechanisms 2. These mechanisms 2 are evenly connected to the frame 1 with bolts, ensuring stable installation and facilitating future disassembly and maintenance. A weed collection box 4 is fixedly connected to the frame 1 via a support frame 3 for uniformly collecting weeds. Each weeding mechanism 2 has a weed collection device 5 fixedly connected to its side away from the direction of travel, ensuring that each mechanism 2 corresponds to one collection device and that no weeds are missed. The bolted connection method allows the number of weeding mechanisms 2 to be increased or decreased according to the required working width, adapting to different plot sizes and avoiding waste of equipment resources. The combination of the weed collection box 4 and the weed collection device 5 solves the problem of weed residue at the source, preventing weed regrowth and subsequent agricultural interference.

[0023] Please see Figure 1 , Figure 3 and Figure 4As shown, the weed collection device 5 consists of a fixed frame 50, collection guides 51, a fixed plate 52, an angle adjustment component 53 for adjusting the angle of the collection guides 51, and a rake 54. One end of the fixed frame 50 is detachably connected to the weeding mechanism 2. The collection guides 51 are symmetrically arranged on both sides of the fixed frame 50 away from the weeding mechanism 2. The arranged collection guides 51 can simultaneously collect and guide weeds from both sides of the weeding mechanism 2 towards the center, avoiding missed collection on one side and improving collection efficiency. Each collection guide 51 includes a first fixed seat 511, a first rotating shaft 512, a fixed rod 513, and a rake guide disc 514. The rake guide disc 514 is rotatably sleeved on the outer wall of one end of the fixed rod 513. The other end of the fixed rod 513 is rotatably connected to the first fixed seat 511 through the first rotating shaft 512, and the first fixed seat 511 is welded to the outer wall of the fixed frame 50. The rotating design of the rake guide disc 514 means that two rake guide discs are arranged during deployment. The 514 has a V-shaped structure. While rotating, the raking guide disc 514 guides the weeds to the front of the central raking rake 54. The angle adjustment component 53 includes a second fixed seat 531, a second rotating shaft 532, and an electric telescopic rod 533. The second fixed seat 531 is welded and fixed to the outer wall of the fixed frame 50 and is located on one side of the first fixed seat 511. The fixed end of the electric telescopic rod 533 is rotatably connected to the second fixed seat 531 through the second rotating shaft 532, and the telescopic end of the electric telescopic rod 533 is rotatably connected to the third fixed seat 535 through the third rotating shaft 534. The third fixed seat 535 is welded and fixed to the outer wall of the middle part of the fixed rod 513. The electric telescopic rod 533 can drive the fixed rod 513 to rotate around the first rotating shaft 512 by telescopic movement, thereby adjusting the angle of the raking guide disc 514. The angle can be adjusted in real time for different crop row spacing or soil looseness to avoid collision between the raking guide disc 514 and crops or soil clumps, thereby improving equipment adaptability and operational safety. The electric telescopic pole 533 is electrically connected to the weeder's built-in power supply via a wire, and a control switch for controlling the start, stop and extension of the electric telescopic pole 533 is connected in series on the wire. This control switch is integrated into the weeder's operation control panel. The control switch integrated into the control panel allows the operator to adjust the angle without leaving the vehicle, reducing labor intensity, while achieving precise quantitative control of the angle, reducing human error and improving the standardization of operations.

[0024] Please see Figure 3 and Figure 5As shown, the fixing plate 52 is fixedly installed on the front outer wall of the fixing frame 50. A connecting through hole 521 is provided on the top of the fixing plate 52 on the side away from the fixing frame 50. This connecting through hole 521 is used to seal and fix the feed end of the external suction conveying pipe. The discharge end of the external suction conveying pipe extends into the internal cavity of the weed collection box 4, and the discharge end port does not contact the inner wall of the weed collection box 4. The sealed connecting through hole 521 prevents weeds from falling from the interface during suction, ensuring collection efficiency. The discharge end of the conveying pipe does not contact the inner wall of the collection box to avoid weeds accumulating and clogging at the discharge end, ensuring a smooth process of suction, conveying and collection. The rake 54 is fixedly installed below the end of the fixed plate 52, and the installation position of the rake 54 corresponds to the position of the connecting through hole 521, ensuring that the weeds collected by the rake 54 can be guided to the connecting through hole 521. The corresponding position of the rake 54 and the connecting through hole 521 realizes a seamless connection of weed collection, guidance and suction, preventing weeds from scattering during the transmission process.

[0025] Workflow: Based on the crop row spacing of the work area, the operator adjusts the extension amount of the electric telescopic rod 533 from the driver's seat using the control switch integrated into the control panel. When the electric telescopic rod 533 extends or retracts, its extension end drives the third fixed seat 535 and the fixed rod 513 to rotate via the third rotating shaft 534, thereby changing the angle of the weeding guide disc 514. The two weeding guide discs 514 are adjusted to form a V-shaped structure that adapts to the crop row spacing, ensuring that the weeding guide disc 514 will not touch the crop stems during operation, while covering the weeds within the working range of the weeding mechanism 2, avoiding missed harvesting or damage to the crops. The connecting through hole 521 connects the external suction equipment and the fixed plate 52, ensuring that the feed end of the suction conveying pipe is sealed and fixed to the connecting through hole 521, and that the discharge end extends into the weed collection box 4 without contacting the box wall. The external suction equipment is started, and the suction pressure is tested to see if it is stable. The suction conveying pipe is checked for blockages or leaks to ensure that the weeds can be smoothly sucked into the weed collection box 4.

[0026] The operator drives the weeder into the work area, moving at a constant speed along the crop rows. The weeding mechanism 2 moves deeper into the soil, cutting into the surface layer with its double-winged hoes according to the preset depth required for crop growth. This cuts and breaks up compacted soil, simultaneously turning over the soil to create a loose topsoil layer, achieving both soil loosening and weed removal. This brings deep soil nutrients to the surface, facilitating root absorption. While the weeding mechanism 2 is operating, the weed collection device 5 operates synchronously. Symmetrically arranged rake guide discs 514 rotate with the machine's movement. Their V-shaped structure guides the weeds turned over by the weeding mechanism 2 from both sides towards the center, preventing them from scattering onto the work path or in the field. The rotating rake guide discs 514 reduce friction with the soil and crops, ensuring smooth movement. Weeds guided to the center are intercepted and further gathered by the rake rake 54, which is fixed below the end of the fixed plate 52 and corresponds to the connecting through hole 521, precisely guiding the gathered weeds. The process proceeds to the connecting through-hole 521, preparing for subsequent suction. The external suction equipment operates continuously, generating negative pressure through the connecting through-hole 521 to draw the weeds guided by the rake 54 into the suction delivery pipe. Because the connecting through-hole 521 is sealed and fixed to the suction delivery pipe, weeds are prevented from falling off the interface during suction, ensuring collection efficiency. The weeds are transported through the suction delivery pipe into the weed collection box 4. Since the discharge end of the suction delivery pipe does not contact the inner wall of the weed collection box 4, it prevents weeds from accumulating and clogging at the discharge end, achieving continuous and smooth collection of weeds and avoiding weed residue in the field.

[0027] This application demonstrates significant benefits of an adjustable agricultural machinery weeding and hoeing machine. By installing a weed collection box 4 on the weeding machine frame 1 and equipping each weeding mechanism 2 with a weed collection device 5, it achieves integrated operation of weeding and hoeing with weed collection and storage. This fundamentally solves the problems of traditional weeding machines leaving weeds in the field and easily reviving after rain, requiring secondary operations. It significantly reduces production costs and operating cycles, while preventing residual weeds from interfering with subsequent agricultural operations such as sowing and fertilization, meeting the needs of modern agricultural precision management. The symmetrically arranged collection guides 51 in the weed collection device 5 have a V-shaped structure, which can guide weeds from both sides to the center simultaneously, working in conjunction with the rake 54 and the sealing... The connected suction and conveying pipe ensures that all weeds are collected without omission and that the transmission is smooth, effectively improving collection efficiency. The electric telescopic rod 533 of the angle adjustment component 53 can adjust the angle of the weeding guide plate 514 in real time through the operation control panel, adapting to different crop row spacings and soil looseness, avoiding damage to crops or equipment, and eliminating the need to stop the machine for adjustment, further improving the convenience and safety of operation. In addition, the bolt connection of the weeding mechanism 2 and the detachable design of the weed collection device 5 facilitate equipment maintenance and adjustment of the operating width, adapting to different plot sizes, reducing equipment resource waste, and the collected weeds can also be used as green manure resources, which is in line with the concept of green agricultural development and has economic, ecological and practical value.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
