Description

Technical Field

[0001] This invention relates to the field of agricultural mechanization engineering technology, specifically to a lodged corn harvesting device. Background Technology

[0002] Traditional corn harvesters face problems such as high loss rates, low harvesting efficiency, and poor machine adaptability when dealing with lodged corn stalks. Traditional devices often rely on fixed cutters and mechanical rollers, which are difficult to effectively pick up and separate lodged stalks, resulting in high grain loss rates and frequently causing machine blockages or damage. To address these challenges, technological development focuses on improving the adaptive design of the harvesting head, such as introducing flexible stalk lifters, sensor-guided navigation systems, and image recognition-based intelligent control systems. These innovations aim to improve adaptability to different lodging angles, reduce manual intervention, and promote the evolution of efficient and low-loss harvesting technologies in the process of modern agricultural mechanization.

[0003] Current lodged corn harvesting devices mainly have the following defects:

[0004] Traditional harvesting devices cannot effectively distinguish corn plants with different degrees of lodging, which makes it impossible for the harvester to dynamically adjust its posture, easily resulting in missed harvests or damage to the plants.

[0011] Furthermore, each of the aforementioned start-stop type rice lifter assemblies includes a slide rod 1.

[0012] Furthermore, each of the aforementioned rotating ring assemblies includes a rotating ring body, which is coaxially arranged with a limiting ring and rotatably connected to the limiting ring.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1-3 As shown, a lodged corn harvesting device includes a harvester body 1, a fixed shaft 2 fixedly connected to the harvester body 1, and a plurality of limiting rings 3 fixedly connected to the fixed shaft 2. The limiting rings 3 are arranged along the axial direction of the fixed shaft 2, and are rotatably connected to a plurality of rotating ring assemblies 4. The limiting rings 3 and the rotating ring assemblies 4 are coaxially arranged, and a plurality of start-stop type seed lifter assemblies 5 are slidably connected to each of the rotating ring assemblies 4. The lower ends of the start-stop type seed lifter assemblies 5 are slidably connected to the limiting rings 3, and the two sides of the rotating ring assemblies 4 are respectively connected to one end of two connecting pipes 6. The connection is fixed, with two adjacent connecting pipes 6 fixedly connected, and several connecting pipes 6 rotatably connected to the fixed shaft 2. Several connecting pipes 6 are coaxially arranged with the fixed shaft 2. One end of the connecting pipes 6 located at both ends of the fixed shaft 2 is fixedly connected to the output end of two drive components 7 respectively. The drive components 7 are fixedly connected to the harvester body 1. A protective cover 8 is provided below one side of the rotating ring assembly 4. The protective cover 8 is fixedly connected to the harvester body 1. A top rod assembly 10 is slidably connected to the right side of the protective cover 8. One end of the top rod assembly 10 is located below the rotating ring assembly 4. One end of the top rod assembly 10 is slidably connected to the claw assembly 20.

[0036] When harvesting lodged corn, as the harvester body 1 moves forward, it activates two drive components 7, causing the connecting pipe 6, which is fixedly connected to it, to rotate on the fixed shaft 2. The rotation of the connecting pipe 6 causes the rotating ring assembly 4 to rotate counterclockwise, which in turn causes several start-stop lifting device assemblies 5, which are slidably connected to it, to rotate synchronously. At the same time, the lower ends of the several start-stop lifting device assemblies 5 slide on the limiting ring 3. Since the degree of lodging of the corn plants is different, the rotation of the several start-stop lifting device assemblies 5 can lift up the corn plants with a less severe lodging, and then the harvester body 1 can harvest them. At the same time, when the rotating ring assembly 4 rotates, the rotation of the rotating ring assembly 4 causes the top rod assembly 10 to slide back and forth on the protective cover 8 assembly, which in turn pushes the claw assembly 20 to slide back and forth synchronously, pushing the more severely lodged corn plants to the side for manual handling.

[0037] Reference Figure 4As shown, both drive components 7 include motors 71, both motors 71 are fixedly connected to the harvester body 1, both motors 71 are located at both ends of the fixed shaft 2, and the output ends of the two motors 71 are fixedly connected to two gears 72 respectively. The connecting pipes 6 located at both ends of the fixed shaft 2 have one end fixedly connected to two gears 73 respectively, and the gears 73 mesh with the gears 72.

[0038] When harvesting lodged corn, the motor 71 is started, which drives the gear 72 fixedly connected to it to rotate. Through the meshing of gear 72 and gear 73, gear 73 rotates together with gear 72, which in turn causes the connecting pipe 6 rotatably connected to the fixed shaft 2 to rotate. The rotation of the connecting pipe 6 drives the rotating ring assembly 4 fixedly connected to the connecting pipe 6 to rotate relative to the limiting ring 3. There are protective plates on the outside of gear 72 and gear 73 to prevent corn stalks from getting stuck between gear 72 and gear 73 and causing them to stop rotating.

[0039] Reference Figure 6 and Figure 8 As shown, several limiting rings 3 are provided with annular grooves 31. The limiting rings 3 are also provided with deflection groove 1 32 and deflection groove 2 33. Deflection groove 1 32 and deflection groove 2 33 are symmetrically arranged on the limiting rings 3. Deflection groove 1 32 and deflection groove 2 33 are located on the same side of the annular grooves 31. The two ends of deflection groove 1 32 and deflection groove 2 33 are connected by straight through grooves 34 respectively.

[0040] When the rotating ring assembly 4 rotates relative to the limiting ring 3, it drives several start-stop rice lifter assemblies 5 to rotate. At the same time, the lower ends of several start-stop rice lifter assemblies 5 slide in the annular groove 31, deflection groove one 32, deflection groove two 33 and straight groove 34.

[0041] Reference Figures 7-8 As shown, each of the several start-stop type rice-lifting device assemblies 5 includes a slide rod 51. The lower end of the slide rod 51 is slidably connected in the deflection groove 32, the deflection groove 33, and the straight groove 34. The slide rod 51 is fixedly connected to one end of the connecting rod 52, and the other end of the connecting rod 52 is fixedly connected to the slide rod 53. The lower end of the slide rod 53 is slidably connected in the annular groove 31, and the upper end of the slide rod 53 is fixedly connected to the rice-lifting rod 54.

[0042] The rotating ring assembly 4 rotates counterclockwise, causing the sliding rod 51, connecting rod 52, and sliding rod 53 to rotate synchronously. The lower end of sliding rod 51 slides in the deflection groove 32, deflection groove 33, and straight groove 34, while sliding rod 53 slides in the annular groove 31. When the lower end of sliding rod 51 slides in the deflection groove 32, sliding rod 53 slides in the annular groove 31, and connecting rod 52 moves synchronously. When the lower end of sliding rod 51 slides from the deflection groove 32 into the straight groove 34, connecting rod 52 deflects during its movement, causing sliding rod 53 to drive the lifting stem 54 to deflect synchronously, causing the lifting stem 54 to deflect towards the side closer to the end face of the rotating ring assembly 4. Figure 1 The clockwise deflection of the support rod 54 means that the support rod 54 is retracted. When the lower end of the sliding rod 51 enters the deflection groove 33 from the straight groove 34, the support rod 54 is completely retracted. The support rod 54 is located between the harvester body 1 and the rotating ring assembly 4. As the rotating ring assembly 4 rotates downward, the support rod 54 rotates to the lowest position of the limit ring 3. When it continues to rotate, the sliding rod 51 passes through the straight groove 34 and re-enters the deflection groove 32. The support rod 54 unfolds again to lift up the fallen corn for harvesting.

[0043] Reference Figure 2 As shown, each of the several rotating ring assemblies 4 includes a rotating ring body 41. The rotating ring body 41 is coaxially arranged with the limiting ring 3 and is rotatably connected to the limiting ring 3. The two sides of the rotating ring body 41 are respectively fixedly connected to one end of two connecting pipes 6. Several inclined top plates 42 are fixedly connected to the rotating ring body 41 and are arranged in a ring on the rotating ring body 41.

[0044] The rotating ring body 41 is driven to rotate by the rotating connecting pipe 6, and the inclined top plate 42 rotates synchronously at the same time.

[0045] Reference Figure 7 As shown, the rotating ring body 41 has several transverse grooves 43 and longitudinal grooves 44. The upper end of the first slide rod 51 is slidably disposed in the transverse groove 43, and the second slide rod 53 is slidably disposed in the longitudinal groove 44.

[0046] When the lower end of slide rod 51 slides in deflection groove 32, slide rod 51 and slide rod 53 are stationary in transverse groove 43 and longitudinal groove 44 respectively. When slide rod 51 enters through groove 34 and slides, slide rod 51 slides in transverse groove 43, while slide rod 53 slides in longitudinal groove 44.

[0047] Reference Figures 9-11As shown, the push rod assembly 10 includes a push rod body 101, which is slidably connected to one side of the protective cover 8. A ball 102 is fixedly connected to one end of the push rod body 101 located outside the protective cover 8. A return spring 103 is sleeved on the push rod body 101, and a slider 104 is fixedly connected to one end of the push rod body 101 located inside the protective cover 8.

[0048] When the rotating ring body 41 rotates, it drives several inclined top plates 42 to rotate together. One of the inclined top plates 42 rotates to a position where it abuts against the ball 102. As it continues to rotate, it pushes the ball 102 to move, which in turn pushes the top rod body 101 to slide on the protective cover 8. At this time, the return spring 103 is compressed. The elastic force of the return spring 103 can overcome the resistance of the vibration spring 112, so that the top rod assembly 10 returns to its initial position. At the same time, the slider 104 moves synchronously until the ball 102 disengages from the inclined top plate 42. The return spring 103 drives the ball 102, the top rod body 101 and the slider 104 to return to their original positions.

[0049] The lower end of slider 104 is slidably connected to slide rail 105. One end of slide rail 105 is fixedly connected to one end of rotating shaft 106. The other end of rotating shaft 106 is rotatably connected to the bottom of the inner cavity of protective cover 8. The other end of slide rail 105 is rotatably connected to one end of amplifying rod 107. The other end of amplifying rod 107 is rotatably connected to slider 2 109. Slider 2 109 is slidably connected to horizontal slide rail 110. Horizontal slide rail 110 is fixedly connected to the bottom of the inner cavity of protective cover 8. Vertical slide rail 111 is fixedly connected to slider 2 109. Slider 2 109 is fixedly connected to one end of vibration spring 112. Hemispherical block 113 is fixedly connected to the other end of vibration spring 112. Hemispherical groove 114 is provided on horizontal slide rail 110.

[0050] When slider 104 is pushed by push rod body 101, since the lower end of slider 104 is slidably connected to slide rail 105, slider 104 slides relative to slide rail 105 during movement. At the same time, slide rail 105 rotates, causing the other end of slide rail 105 to push amplifying rod 107 to deflect, thereby pushing slider 2 109 to slide to the left on horizontal slide rail 110. Simultaneously, it drives vertical slide rail 111 and pawl assembly 20 to slide to the left. Since slider 2 109 and vibrating spring... One end of the spring 112 is fixedly connected, and the other end of the vibration spring 112 is fixedly connected to a hemispherical block 113. The vibration spring 112 and the hemispherical block 113 slide to the left synchronously. When the hemispherical block 113 slides into the hemispherical groove 114, the vibration spring 112 returns to its original position. When it continues to slide, the hemispherical block 113 disengages from the hemispherical groove 114, and the vibration spring 112 is compressed. This process is repeated. Due to the frequent compression and reset of the vibration spring 112, a vibration effect is generated, which in turn causes the slider 109 to also generate a vibration effect.

[0051] The pawl assembly 20 includes a pawl body 201, which is slidably connected to a vertical slide rail 111, and round blocks 202 are fixedly connected to both ends of the pawl body 201.

[0052] When the claw body 201 slides to the left, it causes the circular block 202 to slide synchronously.

[0053] The inner wall of the protective cover 8 is provided with a bend groove 81, and the round block 202 is slidably connected in the bend groove 81.

[0054] When the round block 202 slides horizontally in the angle groove 81, the claw body 201 slides horizontally to the left, causing the round block 202 to slide to the left in the angle groove 81. When the round block 202 slides to the angle groove 81 at an upward angle, as it continues to slide, the claw body 201 slides upward at an angle due to the upward limiting effect of the angle groove 81 on the round block 202. During the entire leftward sliding process, the claw body 201 pushes the corn with a large degree of lodging to the side. At the same time, during the sliding process of the claw body 201, the slider 109 vibrates, causing the claw body 201 to vibrate simultaneously. The claw body 201 is tilted downward, so that the claw body 201 can slide down automatically. Through the vibration, the corn plants that are stuck or wrapped around the claw body 201 slide down.
