Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an intelligent integrated machine for harvesting and storing leeks. Background Technology

[0002] In modern agricultural production, the efficiency and intelligence of agricultural machinery directly affect the planting and harvesting efficiency of crops. Especially in large-scale planting, the application of mechanization can significantly improve agricultural production efficiency. However, existing leek harvesting equipment has many problems in practical application, hindering its further promotion and use. Traditional leek harvesters are usually single-function, only able to complete one step of cutting or collecting, resulting in cumbersome and inefficient operations. At the same time, the design of these devices often fails to adequately consider operational safety and crop protection, easily damaging the leeks and affecting the product's appearance quality and market value. Furthermore, existing equipment lacks flexibility, making it difficult to adapt to the needs of different planting scales, and its high maintenance costs may increase the economic burden on farmers in the long run.

[0003] On the other hand, with the advancement of agricultural modernization, farmers have placed higher demands on the ease of operation, comfort, and environmental performance of machinery and equipment. Traditional equipment typically requires manual intervention to complete cutting and harvesting, resulting in high labor intensity and low efficiency, failing to meet the needs of modern high-efficiency agricultural production. Especially in complex terrain conditions, the stability and maneuverability of the equipment face challenges, and it is prone to damaging soil structure due to ground compaction. Therefore, developing an intelligent leek harvesting device that integrates cutting, harvesting, conveying, and collection can not only simplify the operation process and improve work efficiency, but also effectively protect crops and soil structure, reduce labor intensity, and minimize environmental impact. The emergence of such equipment will provide strong support for the improvement of agricultural production methods and industrial upgrading, while also better meeting market demands and promoting sustainable agricultural development. Utility Model Content

[0004] This utility model addresses the problems of low operational safety, high maintenance costs, poor flexibility, limited functionality, and severe product damage associated with existing leek harvesting equipment. Therefore, this utility model adopts the following technical solution:

[0005] This utility model provides an intelligent integrated machine for harvesting and storing chives, including a frame, a walking device, a supporting device, a cutting device, and a conveying and collecting device. The frame serves as the supporting framework for the overall structure, bearing and fixing each functional module. The walking device is located at the bottom of the machine, enabling stable movement of the equipment in the field. The supporting device is installed at the front of the frame, supporting and uprighting the chive plants using a lifting guide plate and lifting wheels. The cutting device is located behind the supporting device, using a motor-driven cutting blade to precisely cut the chives. The conveying and collecting device is located behind the cutting device, transporting the cut chives to the collecting area via a conveyor belt.

[0006] Furthermore, the walking device consists of multiple large serrated anti-slip wheels. Each large serrated anti-slip wheel has serrated protrusions on its outer surface, which prevent the equipment from compacting the ground when moving in the field and enhance its mobility in wet or soft terrain. There are eight large serrated anti-slip wheels, evenly distributed on both sides of the frame, four on each side. The walking device is driven by a motor, and the motor output is connected to the large serrated anti-slip wheels via a drive shaft. A gear set is installed on the drive shaft to transmit power.

[0007] Specifically, the supporting device consists of two symmetrically arranged lifting units, each including a lifting guide plate and a lifting wheel. The lifting guide plate is inclined, with its bottom surface in contact with the ground, used to guide leek plants that are leaning or lying down. The lifting wheel is rotatably mounted on top of the lifting guide plate via bearings, and its outer surface is provided with serrations made of flexible material. During rotation, the serrations cooperate with the lifting guide plate to lift the leek plants upright and guide them into the working area of ​​the cutting device.

[0008] Furthermore, the cutting device includes a second motor, a cutting drive shaft, a cutting driven shaft, and a cutting blade. The second motor is fixedly mounted on the frame, and its output end is connected to the cutting drive shaft via a coupling.

[0009] Specifically, the transmission and collection device includes a mounting plate, a first motor, a transmission mechanism, a first drive shaft, a second drive shaft, a first transmission roller, a second transmission roller, a first drive roller, a second drive roller, a first transmission belt, and a second transmission belt. The mounting plate is fixedly mounted on the frame to support the entire transmission and collection system. The first motor is fixedly mounted on the mounting plate with screws, and its output end is connected to the first and second drive shafts through the transmission mechanism. The transmission mechanism includes a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a synchronous belt. The first synchronous pulley is fixedly sleeved on the output end of the first motor, the second and third synchronous pulleys are respectively fixedly sleeved on the outside of the first and second drive shafts, and the synchronous belt is assembled on the outside of the first, second, and third synchronous pulleys to realize power transmission.

The surfaces of the first and second transmission belts have raised structures made of flexible material for combing and protecting the cut chives during transmission.

[0011] Specifically, the intelligent leek harvesting and storage integrated machine also includes a microcontroller control system. This system is connected to the first and second motors via signal lines to control the motors' start / stop and operating speed. The microcontroller control system adjusts the height of the cutting blades and the speed of the conveyor belt according to a preset program, thereby achieving precise cutting and efficient transport of leeks of different heights.

[0012] The beneficial effects of this invention are as follows: Through integrated design and modular combination, the equipment enables integrated operation of leek harvesting, transportation, and collection. Specifically, the large serrated anti-slip wheels of the walking device prevent the equipment from compacting the ground when walking in the field, enhancing its passability and stability; the support device's guide plate and support wheel design minimize damage to leek plants during harvesting; the cutting device achieves precise movement of the cutting blades through gear meshing transmission, ensuring cutting efficiency and quality; the spiral conveyor belt design of the transportation and collection device not only improves the transportation efficiency of leeks but also effectively protects the leeks through a flexible raised structure. Furthermore, the introduction of a single-chip microcomputer control system enables automated operation of the equipment, significantly reducing manpower requirements and improving operational safety.

[0013] In particular, this invention utilizes a modular design, allowing the equipment to be flexibly adjusted to suit different planting scales and needs. For example, users can select different numbers of support devices and conveying / collecting devices according to actual needs, thereby adapting to leek planting areas of varying widths. This design not only improves the equipment's applicability but also reduces long-term operating costs, making the equipment easier to maintain and clean.

[0014] Furthermore, this invention reduces energy consumption during equipment operation and mitigates environmental impact by optimizing the energy management system and employing energy-efficient motors and transmission mechanisms.

[0024] This utility model provides an intelligent integrated machine for harvesting and storing chives. The specific embodiments of this utility model are described in detail with reference to the accompanying drawings. The equipment includes a frame 1, a walking device, a support device 3, a cutting device, and a conveying and collecting device 4. The frame 1 serves as the supporting framework for the overall structure, bearing and fixing each functional module to ensure the stability and reliability of the equipment during field operations. The walking device is located at the bottom of the machine and is used to move the equipment in the field. The support device 3 is installed at the front of the frame 1 and supports the chive plants upright using a support guide plate 31 and a support wheel 32. The cutting device is located behind the support device 3 and uses a motor-driven cutting blade 7 to precisely cut the chives. The conveying and collecting device 4 is located behind the cutting device and transports the cut chives to the collection area via a conveyor belt.

[0025] In practical implementation, the walking device consists of multiple large serrated anti-slip wheels 2. Each large serrated anti-slip wheel 2 has serrated protrusions on its outer surface, which prevent the equipment from compacting the ground when moving in the field and enhance its mobility in wet or soft terrain. There are eight large serrated anti-slip wheels 2, evenly distributed on both sides of the frame 1, four on each side. The walking device is driven by a motor, and the motor output is connected to the large serrated anti-slip wheels 2 via a drive shaft. A gear set is installed on the drive shaft to transmit power. In actual operation, when the equipment starts, the motor drives the drive shaft to rotate, and the gear set on the drive shaft transmits power to the large serrated anti-slip wheels 2, allowing them to move smoothly in the field. This design not only avoids the problem of ground compaction caused by traditional tracked tires but also improves the equipment's adaptability to complex terrain.

[0026] The support device 3 consists of two symmetrically arranged lifting units, each including a lifting guide plate 31 and a lifting wheel 32. The lifting guide plate 31 is inclined, with its bottom surface in contact with the ground, used to guide leeks that are leaning or lying down. The lifting wheel 32 is rotatably mounted on top of the lifting guide plate 31 via bearings. The outer surface of the lifting wheel 32 is provided with flexible material teeth that cooperate with the lifting guide plate 31 during rotation, lifting the leeks upright and guiding them into the working area of ​​the cutting device. In actual operation, as the equipment moves, the lifting guide plate 31 travels close to the ground, and the leaning leeks are lifted upright by the curved lifting guide plate 31 and the lifting wheel 32, entering the clamping and conveying device. This design effectively reduces damage to the leeks during harvesting while improving cutting efficiency.

[0027] The cutting device includes a second motor 5, a cutting drive shaft, a cutting driven shaft, and a cutting blade 7. The second motor 5 is fixedly mounted on the frame 1, and its output end is connected to the cutting drive shaft via a coupling. A drive gear 6 is fixedly fitted onto one end of the cutting drive shaft, and a driven gear is fixedly fitted onto one end of the cutting driven shaft. The drive gear 6 and the driven gear mesh to transmit power. The cutting blade 7 is fixedly mounted to the bottom end of the cutting driven shaft with screws, and its cutting edge faces downwards from the base plate of the frame 1. It is used for precise cutting of the stems of the chive plants. In actual operation, when the equipment moves to the chive planting area, the second motor 5 starts, driving the cutting drive shaft to rotate via the coupling. The drive gear 6 on the cutting drive shaft meshes with the driven gear on the cutting driven shaft, thereby driving the cutting blade 7 to rotate. The cutting blade 7 cuts the chive plants at a preset height, ensuring cutting efficiency and quality. This design mimics manual harvesting, achieving precise and efficient cutting of chives.

[0028] The transmission and collection device 4 includes a mounting plate 41, a first motor 42, a transmission mechanism 43, a first drive shaft 44, a second drive shaft 45, a first transmission roller 46, a second transmission roller 47, a first drive roller 401, a second drive roller 402, a first transmission belt 48, and a second transmission belt 49. The mounting plate 41 is fixedly mounted on the frame 1 to support the entire transmission and collection system. The first motor 42 is fixedly mounted on the mounting plate 41 with screws, and its output end is connected to the first drive shaft 44 and the second drive shaft 45 through the transmission mechanism 43. The transmission mechanism 43 includes a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a synchronous belt. The first synchronous pulley is fixedly sleeved on the output end of the first motor 42. The second and third synchronous pulleys are respectively fixedly sleeved on the outside of the first drive shaft 44 and the second drive shaft 45. The synchronous belt is assembled on the outside of the first, second, and third synchronous pulleys to achieve power transmission. The first drive shaft 44 and the second drive shaft 45 are rotatably mounted on the frame 1 via bearings. A first drive roller 401 and a second drive roller 402 are respectively fixedly sleeved on the outside of the first drive shaft 44 and the second drive shaft 45. A first transfer roller 46 and a second transfer roller 47 are rotatably mounted near the front end of the frame 1 via bearings. A spiral conveyor belt 48 is sleeved between the first transfer roller 46 and the first drive roller 401, and a spiral conveyor belt 49 is sleeved between the second transfer roller 47 and the second drive roller 402. The surfaces of the first transfer belt 48 and the second transfer belt 49 have raised structures made of flexible material, used to comb and protect the cut chives during transport. In actual operation, after the cutting device completes the cutting of the chives, the cut chives are transported to the collection area via the first transfer belt 48 and the second transfer belt 49. The spiral design of the first transfer belt 48 and the second transfer belt 49 improves the transport efficiency of the chives, while the flexible raised structures effectively protect the chives, avoiding secondary damage during transport.

[0029] The intelligent leek harvesting and storage integrated machine also includes a microcontroller control system. This system is connected to the first motor 42 and the second motor 5 via signal lines, controlling their start / stop and operating speed. The microcontroller control system adjusts the height of the cutting blade 7 and the operating speed of conveyor belts 48 and 49 according to a preset program, achieving precise cutting and efficient transport of leeks at different heights. In actual operation, the operator sets the cutting height and transport speed through the microcontroller control system, and the equipment automatically completes the entire process of leek harvesting, transporting, and collecting based on the set parameters. This design automates the operation of the equipment, significantly reducing manpower requirements and improving operational safety.

[0030] The equipment features a modular design, allowing users to select different numbers of support devices 3 and conveying / collecting devices 4 to suit varying leek planting areas. For example, in narrow planting areas, the number of support devices 3 and conveying / collecting devices 4 can be reduced; in wide planting areas, the number of corresponding modules can be increased. This design improves the equipment's applicability while reducing long-term operating costs and making it easier to maintain and clean. Furthermore, the equipment utilizes energy-efficient motors and high-efficiency transmission mechanisms, optimizing the energy management system to reduce energy consumption during operation and minimize environmental impact. This design aligns with the requirements of sustainable development in modern agriculture and has significant potential for widespread adoption.

[0031] In practical applications, the intelligent leek harvesting and storage machine is suitable for various leek-growing areas, from small family farms to large agricultural cooperatives, and can be flexibly configured to meet their needs. For example, during the peak spring leek harvesting season, the machine can quickly complete the harvesting of large areas of leeks, significantly improving production efficiency. In the later stages of the autumn leek harvest, the machine can adapt to different planting densities and harvesting requirements by adjusting the number of support devices 3 and transmission and collection devices 4. Through integrated design and modular combination, the machine solves the problems of low operational safety, high maintenance costs, poor flexibility, limited functionality, and severe product damage found in existing leek harvesting equipment, significantly improving the efficiency and quality of leek harvesting and demonstrating broad application prospects.
