Description

Technical Field

[0001] This utility model relates to the field of corn ear picking, and in particular to a handle-type low-damage ear picking device for fresh corn. Background Technology

[0002] With its tender, juicy, and nutritious characteristics, fresh sweet corn has seen a continuous increase in market demand. The handle-type low-damage ear-picking device for fresh sweet corn is an agricultural machinery device used in the harvesting process of fresh sweet corn to reduce ear damage and improve harvest quality. It is mainly used in the mechanized harvesting of fresh sweet corn and can be installed on equipment such as fresh sweet corn harvesters to improve harvesting efficiency, reduce manual labor intensity, and ensure harvest quality. It is suitable for farmland with large-scale cultivation of fresh sweet corn.

[0003] This device moves in rows in the field and is generally composed of components such as ear-picking rollers. First, the harvesting blades cut the fresh corn stalks. The active reel is driven by a drive source to rotate and pushes and combs the fresh corn stalks toward the cut and ear-picking parts through the picker plate, assisting in supporting the stalks. The passive reel rotates by contact with the crop, the active reel, or other moving parts of the equipment, driven by the pushing force of the crop or the overall movement of the equipment, further combing and straightening the fresh corn stalks, making the transport smoother.

[0004] Because fresh corn kernels are tender, they are easily damaged during mechanized harvesting. Ordinary corn harvesting headers use a forced stalk pulling and ear-picking method, and the ear-picking plate during ear picking can easily damage the ears, seriously affecting the appearance of the ears and causing significant economic losses. Utility Model Content

[0005] To overcome the technical problem of ordinary corn harvesters using forced stalk pulling and ear-plucking techniques, where the ear-plucking plate easily damages the ears during the ear-plucking process.

[0006] The technical solution of this utility model is as follows: a handle-type low-damage ear-picking device for fresh corn, including a mounting frame, an ear-picking roller, and an ear-picking assembly. A mounting plate one is fixedly connected to the lower part of the mounting frame, and support frames are fixedly connected to both sides of the mounting plate one. A mounting plate two is fixedly connected to the other side of the support frames. A drive gearbox is provided on one side of the mounting plate one, and an ear-picking assembly is provided on the other side of the mounting plate one. A pulley is rotatably connected to one side of the mounting plate one, and a drive belt is connected to the top of the pulley. The output end of the drive gearbox is connected to the pulley. Two sets of rotating plates are rotatably connected to one side of the mounting plate one. The rotating plates are rotatably connected to the pulley. An ear-picking roller is fixedly connected to the top of the rotating plate. The other side of the ear-picking roller is rotatably connected to the mounting plate two. The two sets of ear-picking rollers mesh with each other, and the two sets of ear-picking rollers rotate in opposite directions.

[0007] Preferably, two sets of ear-picking baffles are fixedly connected to the top of the support frame.

[0008] Preferably, a support plate is fixedly connected above the ear-picking baffle.

[0009] Preferably, an active reel is rotatably connected to the top of the mounting frame.

[0010] Preferably, a passive reel is rotatably connected above the support plate.

[0011] Preferably, a rubber reel belt is connected to the upper drive of the active reel and the passive reel.

[0012] Preferably, a shovel plate is fixedly connected to the outer side of the rubber shovel belt, and the shovel plates are evenly distributed on the outer side of the rubber shovel belt.

[0013] The beneficial effects of this utility model are as follows: Through ingenious structural design, the output end of the drive gearbox is connected to the pulley, and the transmission belt causes two sets of pulleys to rotate. The rotation of the pulleys drives the rotating plate to rotate, thereby causing the ear-picking rollers to rotate. With the two sets of ear-picking rollers meshing with each other and rotating in opposite directions, after the fresh corn stalks enter the device, the relative rotation generates an effect that pulls the stalks downwards on the one hand and pinches the stalks on the other. Since the fresh corn ears have long ear stalks, the ear stalks are pinched first during ear picking, allowing the ears and ear stalks to separate first, greatly reducing the mechanical impact during the ear picking process. The ear picking baffle, through its inclined surface design, forms a lateral constraint on the stalks, forcing the stalks into the meshing gap between the two sets of ear-picking rollers, preventing ear picking failure or ear damage due to the stalks being placed haphazardly.

Detailed Implementation

[0020] Corn, belonging to the genus *Zea* of the Poaceae family, is an annual herbaceous plant. Its tall, robust stems make it an important food, feed, and industrial raw material crop. Botanically, corn has a well-developed, fibrous root system that penetrates deep into the soil to absorb water and nutrients; its stalks are erect, typically 1-4 meters tall, with distinct internodes; its leaves are large, lanceolate, and have a waxy layer to reduce water evaporation. Corn flowers are unisexual, with male and female flowers on the same plant. Male flowers grow at the top of the plant, while female flowers grow in the leaf axils. After pollination and fertilization, it produces abundant fruit, the common corncob. Nutritionally, corn is considered a "golden crop," rich in carbohydrates, a major source of energy for the human body; it also contains a certain amount of protein, fat, vitamins, and minerals. It is particularly high in B vitamins, such as B1, B2, and niacin, which play an important role in maintaining metabolism and the health of the nervous system. Furthermore, corn contains dietary fiber, which promotes intestinal peristalsis and prevents constipation. It is worth mentioning that different varieties of corn have slightly different nutritional values. For example, sweet corn has a higher sugar content, while glutinous corn has a unique taste and nutritional characteristics.

[0021] In the harvesting of sweet corn, the stalk-pinching low-damage sweet corn ear-picking device is a mechanized agricultural equipment that assists in the harvesting of corn. It is mainly used for efficient and low-damage ear-picking of sweet corn. Its working principle is to use a specific mechanical structure to precisely act on the stalk where the corn ear connects to the stalk. Through an action similar to manually pinching off the stalk, the mature sweet corn ear is detached from the plant, while minimizing damage to the ear and the plant. The device generally consists of a power system, a positioning and clamping mechanism, a stalk-pinching actuator, and a collection and conveying device. During operation, the positioning and clamping mechanism first firmly clamps the corn stalk to ensure the target ear is accurately positioned. Then, the stalk-pinching actuator performs a precise and gentle pinching operation according to the set action pattern, allowing the ear to fall naturally onto the collection tray or conveyor belt below. Finally, the sweet corn ears are transported to a storage container by the conveying system. Compared to traditional manual ear picking, the handle-type low-damage ear picking device for sweet corn can significantly improve harvesting efficiency and reduce labor intensity, making it particularly suitable for large-scale sweet corn planting bases. However, when using it, attention should be paid to adjusting parameters such as positioning accuracy and handle force to avoid damage to the ears and plants due to improper operation. It should also be used in conjunction with reasonable corn planting density and field management to ensure a smooth mechanical harvesting process and contribute to the efficient and high-quality harvesting of sweet corn.

[0022] The pinch-handle type low-damage ear-picking device for sweet corn is an operational tool designed for sweet corn harvesting, emphasizing low loss and high efficiency. It is commonly used during the ripening and pre-harvest stage of sweet corn to ensure ear quality and post-harvest value. The device relies on a precise mechanical structure adapted to the morphology of sweet corn plants and the characteristics of ears. During operation, a specific mechanism identifies and positions the stalk connecting the corn ear to the stalk. The device first adapts and fixes the corn stalk or ear perimeter, then the pinch-handle actuator simulates the gentle pinching action of a human hand. Utilizing a rational mechanical design, it precisely applies force to the stalk, allowing the ear to detach from the plant under uniform and controllable force. This avoids the damage to tender kernels and ears caused by hard friction and compression, as seen in ordinary harvesting headers that forcefully pull the stalk or use a stalk-picking method. To reduce bumps and knocks during ear collection, the device is equipped with suitable flexible collection components, such as a conveyor channel with a buffer layer and a temporary storage structure with adjustable stacking height, reducing squeezing and friction between ears. Because fresh corn kernels are delicate and extremely sensitive to harvesting damage, this device focuses on optimizing aspects such as the precision of mechanical movements, the material and shape of contact components. For example, the pinching handle component uses a wear-resistant and somewhat elastic material, ensuring the effectiveness of pinching the stalk while reducing impact on the ear. During operation, equipment parameters need to be adjusted appropriately to adapt to the differences in stalk thickness and toughness among different varieties of fresh corn, ensuring stable and low-loss ear picking. Although the pinching-handle type low-loss ear picking device for fresh corn has certain operational requirements in equipment debugging and initial adaptation, it can significantly reduce damage during mechanized harvesting of fresh corn, ensuring the appearance and quality of the ears. It is particularly well-suited to the production needs of high-quality fresh corn and, due to its low-loss and high-efficiency advantages, is gradually becoming an important harvesting equipment in large-scale fresh corn planting bases and premium corn orchards.

[0023] Compared to traditional manual ear picking, the pinch-handle type low-damage ear picking device for sweet corn significantly improves harvesting efficiency, reduces manual labor intensity, and is suitable for the harvesting needs of large-scale sweet corn planting. When using it, parameters such as positioning accuracy and pinching force need to be adjusted according to the corn variety and planting density, while also coordinating with reasonable field management, such as maintaining uniform plant growth, to ensure smooth mechanical harvesting. It has significant advantages in ensuring the integrity of sweet corn ears, providing strong support for the mechanized and high-quality harvesting of the sweet corn industry.

[0024] Currently, mechanized harvesting of sweet corn has significant shortcomings. Because sweet corn kernels are delicate, the forced stalk pulling and ear-picking methods used in ordinary corn harvesting headers easily damage the ears. The ear-picking plate used during ear-picking directly damages the appearance of the ears, severely affecting their commercial value and causing significant economic losses to growers. This harvesting method does not fully consider the characteristics of sweet corn kernels. In actual operation, it not only fails to meet the demand for low-damage harvesting of sweet corn but also struggles to adapt to the large-scale, high-quality production requirements of modern sweet corn industries. Therefore, it is urgent to address the damage problem and improve the quality of mechanized harvesting of sweet corn by improving the structure of harvesting equipment and optimizing harvesting processes.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-5 This utility model provides an embodiment: a handle-type low-damage ear-picking device for fresh corn, including a mounting frame 101, an ear-picking roller 109, and an ear-picking assembly. A mounting plate 102 is fixedly connected to the lower part of the mounting frame 101. Support frames 103 are fixedly connected to both sides of the mounting plate 102. A mounting plate 104 is fixedly connected to the other side of the support frame 103. A drive gearbox 105 is provided on one side of the mounting plate 102, and an ear-picking assembly is provided on the other side. A pulley 106 is rotatably connected to one side of the mounting plate 102. A drive belt 107 is connected to the top of the pulley 106. The output end of the drive gearbox 105 is connected to the pulley 106. Two sets of rotating plates 108 are rotatably connected to one side of the mounting plate 102. The rotating plates 108 are rotatably connected to the pulley 106. An ear-picking roller 109 is fixedly connected to the top of the rotating plates 108. 9. The other side of the ear-picking roller 109 is rotatably connected to the mounting plate 104. The two sets of ear-picking rollers 109 mesh with each other and rotate in opposite directions. The drive gearbox 105 is started and driven. The output end of the drive gearbox 105 is connected to the pulley 106. The two pulleys 106 rotate through the transmission belt 107. The rotation of the pulleys 106 drives the rotating plate 108 to rotate, thereby making the ear-picking roller 109 rotate. With the two sets of ear-picking rollers 109 meshing with each other and rotating in opposite directions, after the fresh corn stalks enter the device, the relative rotation will pull the stalks downward on the one hand and break the stalks on the other. Since the fresh corn ears have long ear stalks, the ear stalks are broken first when picking the ears, so that the ears and ear stalks are separated first, which greatly reduces the mechanical impact during the ear picking process, achieves low-damage ear picking, and allows the ears to be harvested more intact.

[0027] Please see Figures 2-5In this embodiment, two sets of ear-picking baffles 201 are fixedly connected above the support frame 103, and a support plate 202 is fixedly connected above the ear-picking baffles 201. When the fresh corn stalks are transported to the ear-picking area, the ear-picking baffles 201 form a lateral constraint on the stalks through the inclined surface design, forcing the stalks into the meshing gap of the two sets of ear-picking cutter rollers 109, allowing the stalks to be transported along the preset path, avoiding ear-picking failure or damage to the ears due to the stalks being placed haphazardly.

[0028] Please see Figures 1-4 In this embodiment, an active reel 301 is rotatably connected above the mounting frame 101, and a passive reel 302 is rotatably connected above the support plate 202. A rubber reel belt 303 is drive-connected above the active reel 301 and the passive reel 302. A scooping plate 304 is fixedly connected to the outer side of the rubber reel belt 303. The scooping plate 304 is evenly distributed on the outer side of the rubber reel belt 303. A driving device provides power to the active reel 301, causing the active reel 301 to rotate around its own axis. Through the meshing structure with the rubber reel belt 303, the power is transmitted to the rubber reel belt. The belt 303 drives the rubber reeling belt 303 to circulate. The rotation of the rubber reeling belt 303 drives the passive reeling wheel 302 to rotate. The reeling plates 304 on the outer side of the rubber reeling belt 303 are evenly distributed. When the rubber reeling belt 303 moves, the reeling plates 304 will insert into the bottom or side of the fresh corn stalks, grab and transport the stalks. The rubber can quickly return to its original shape after being stressed. When the device is working, the rubber reeling belt 303 transports the stalks, which causes compression and stretching. The elasticity of the rubber allows the rubber reeling belt 303 and the reeling plates 304 to remain undeformed, ensuring stable transport. It can also buffer the impact of the stalks and protect the ears of corn.

[0029] During operation, the drive device provides power to the active reel 301, causing it to rotate around its own axis. Through its meshing structure with the rubber reel belt 303, the power is transmitted to the rubber reel belt 303, driving it to circulate. The rotation of the rubber reel belt 303 drives the passive reel 302 to rotate. The evenly distributed webbing plates 304 on the outer side of the rubber reel belt 303, as it moves with the belt, insert into the bottom or side of the fresh corn stalks, grabbing and transporting them. When the rubber is subjected to force, it can quickly return to its original shape. When the device is working, the rubber conveyor belt 303 transports straw, which is squeezed and stretched. The elasticity of the rubber allows the rubber conveyor belt 303 and the conveyor plate 304 to remain undeformed, ensuring stable transport. It can also buffer the impact of straw and protect the ears. When the fresh corn stalks are transported to the ear-picking area, the ear-picking baffle 201 forms a lateral constraint on the stalks through the inclined surface design, forcing the stalks into the meshing gap of the two sets of ear-picking rollers 109, allowing the stalks to be transported along the preset path, avoiding ear-picking failure or damage to the ears due to the stalks being placed haphazardly.

[0030] Through the above steps, the output end of the drive gearbox 105 is connected to the pulley 106, and the two sets of pulleys 106 are rotated by the transmission belt 107. The rotation of the pulleys 106 drives the rotating plate 108 to rotate, thereby causing the ear-picking roller 109 to rotate. The two sets of ear-picking rollers 109 mesh with each other and rotate in opposite directions. After the fresh corn stalks enter the device, the relative rotation generates an effect that pulls the stalks downward on the one hand and breaks the stalks on the other. Since the fresh corn ears have long ear stalks, the ear stalks are broken first when picking the ears, so that the ears and ear stalks are separated first, which greatly reduces the mechanical impact during the ear-picking process, achieves low-damage ear picking, and allows the ears to be harvested more intact.
