Description

Technical Field

[0001] This utility model relates to the technical field of corn harvesters, and in particular to an anti-tangling corn harvester ear-picking guide device. Background Technology

[0002] A corn harvester is an agricultural implement used to mechanically complete various production processes of corn harvesting, including stalk cutting, ear picking, husking, threshing, straw processing, and post-harvest tillage, depending on the planting method and agronomic requirements. The ear picking device is the core component of the corn harvester, separating the corn ears from the stalks during the harvesting process. Existing technology publication number CN209449242U discloses an ear picking device for a corn harvester. The device includes a gearbox, stalk-pulling rollers, and ear-picking plates. Two stalk-pulling rollers are mounted on the gearbox. Above each roller is a support rod fixedly connected to the side wall of the gearbox. An ear-picking plate is fitted onto each support rod, with the support rod located at the outer edge of the ear-picking plate. An inclined plate is positioned on the opposite side wall of each ear-picking plate, arranged in a V-shape. Below each ear-picking plate is a rotating shaft adjacent to the inclined plate, driven by the gearbox. The section of the shaft opposite the ear-picking plate has a cam-shaped cross-section. A first limiting plate is positioned above each ear-picking plate. However, the structure is relatively fixed and cannot be adjusted for different varieties and sizes of corn, resulting in poor applicability for ear-picking operations on different varieties and sizes of corn. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an anti-tangling corn harvester ear-picking guide device that can be adjusted according to the size of the corn to be harvested, is easy to adjust, has high adjustment accuracy, and saves time and effort.

[0004] This utility model discloses an anti-tangle corn harvester ear-picking guide device, comprising a frame, two stalk-pulling rollers, a drive box, two drive gears, two inclined ear-picking plates, an adjustment component, and a conveying component. The two stalk-pulling rollers are rotatably mounted inside the frame. The drive box is mounted on the rear side wall of the frame, and the drive gears are rotatably mounted inside the drive box. The two drive gears mesh, and the input ends of the stalk-pulling rollers are respectively connected to the drive gears. The two inclined ear-picking plates are mounted on the top of the frame through the adjustment component, and the conveying component is installed on the inclined ear-picking plates. The drive gears are connected to the drive component of the harvester, and the two drive gears drive the stalk-pulling rollers to rotate. The adjustment component can move the inclined ear-picking plates closer to or further apart, thereby adjusting the spacing between the inclined ear-picking plates, which is used for ear-picking of corn of different varieties and sizes. The conveying component enables rapid ear-picking of corn.

[0005] Preferably, the adjusting components include two rotating rods, two sets of adjusting sliders, two sets of push frames, two sets of adjusting arms, two connecting blocks, and two sets of plug-in rods. Adjusting grooves are provided on the upper left and right sides of the frame. The rotating rods are rotatably installed within the adjusting grooves, and symmetrical threaded grooves are provided on the rotating rods. The adjusting sliders are slidably installed within the adjusting grooves, and two adjusting sliders are symmetrically screwed onto the rotating rods. A push frame is installed inside the adjusting slider. One end of the adjusting arm is rotatably connected to the push frame. A connecting block is installed at the bottom of the inclined ear-picking plate, and two plug-in rods are installed at the bottom of the connecting block. A rotating hole is provided at the end of the adjusting arm away from the push frame, and the plug-in rods are inserted into the rotating hole. Rotating the rotating rods pushes the adjusting sliders to move within the adjusting grooves, thereby pushing the connecting blocks through the push frames and adjusting arms, causing the inclined ear-picking plates to move closer or further apart, thus adjusting the spacing between the inclined ear-picking plates and performing ear-picking work for different varieties and sizes of corn.

[0006] Preferably, the machine also includes two sets of limiting slide rods and two adjusting nuts. The limiting slide rods are fixedly installed at the front and rear ends of the bottom of the inclined ear-picking plate. The top of the frame has a limiting slide groove that matches the limiting slide rod. The limiting slide rod is slidably installed in the limiting slide groove. The front end of the frame has a drive groove, and the front end of the rotating rod extends into the drive groove and is fitted with an adjusting nut. The adjusting nut allows the rotating rod to be rotated by a hex wrench for easy adjustment. When the inclined ear-picking plate moves, it drives the limiting slide rod to slide in the limiting slide groove, providing limiting support for the inclined ear-picking plate, increasing structural strength, ensuring stability, and improving service life.

[0007] Preferably, the conveying component includes two sets of mounting frames, two sets of sprockets, two conveyor chains, multiple actuating blocks, and two hydraulic motors. Mounting frames are installed at the front and rear of the inclined ear-picking plate. Sprockets are rotatably mounted on the mounting frames. A conveyor chain is installed between the front and rear sprockets. Multiple actuating blocks are installed on the conveyor chain. The hydraulic motors are mounted on the top of the rear mounting frames, and the output end of the hydraulic motors is connected to the input end of the sprockets. The hydraulic motors drive the sprockets to rotate, which in turn drives the conveyor chain to rotate. The actuating blocks actuate the material, enabling rapid ear picking of corn and improving practicality.

[0008] Preferably, it also includes two sets of stem-pulling plates and multiple anti-clogging cones. Multiple stem-pulling plates are evenly installed at the rear end of the stem-pulling roller, and the stem-pulling plates on the left and right sides are arranged crosswise. Multiple anti-clogging cones are evenly installed on the outer wall of the stem-pulling roller. The stem-pulling roller rotates and pushes the stem into the space between the stem-pulling plates. The stem-pulling plates pull the stem down to separate it from the corn ear, thus achieving the function of separating the stem. The anti-clogging cones can effectively tear the stem, thereby effectively preventing clogging between the two stem-pulling rollers.

[0009] Preferably, it also includes two guide cones, which are respectively installed at the front end of the stem pulling roller; the guide cones can separate the stems.

[0010] Preferably, it also includes two dividing plates and two protrusions. The two dividing plates are respectively installed on the left and right sides of the front end of the frame, and the protrusions are installed on the left and right sides of the inner wall of the frame. The stalks are separated by the drive box during the movement of the harvester.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the drive gear is connected to the drive component of the harvester, and the stalk-pulling roller is driven to rotate through the two drive gears. The adjustment component can drive the inclined ear-picking plates to move closer or further apart, thereby adjusting the spacing between the inclined ear-picking plates, which can be used to pick ears of corn of different varieties and sizes. The corn ear picking can be carried out quickly through the conveying component. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, two stem-pulling rollers 2 are rotatably installed inside the frame 1. The drive box 3 is installed on the rear side wall of the frame 1. A drive gear 4 is rotatably installed inside the drive box 3. The two drive gears 4 mesh. The input ends of the stem-pulling rollers 2 are connected to the drive gears 4 respectively. Adjustment grooves are opened on the upper part of the left and right sides of the frame 1. The rotating rod 9 is rotatably installed in the adjustment groove. The rotating rod 9 has symmetrically opened threaded grooves. The adjusting slider 10 is slidably installed in the adjustment groove. The two adjusting sliders 10 are symmetrically screwed onto the rotating rod 9. A push frame 11 is installed inside the adjusting slider 10. One end of the adjusting arm 12 is rotatably connected to the push frame 11. A connecting block 13 is installed at the bottom of the inclined ear-picking plate 15. Two plug-in rods 14 are installed at the bottom of the connecting block 13. A rotating hole is opened at the end of the adjusting arm 12 away from the push frame 11. The plug-in rods 14 are inserted into the rotating hole. Limiting slide rods 16 are fixedly installed at the front and rear ends of the bottom of the inclined ear-picking plate 15. The top of the frame 1 is provided with a limiting groove that matches the limiting slide rod 16. The limiting slide rod 16 is slidably installed in the limiting groove. The front end of the frame 1 is provided with a drive groove. The front end of the rotating rod 9 extends into the drive groove and is equipped with an adjusting nut 17. The inclined ear-picking plate 15 is equipped with mounting brackets 18 at the front and rear. A sprocket 19 is rotatably installed on the mounting bracket 18. A conveyor chain 20 is installed between the front and rear sprockets 19. Multiple actuating blocks 21 are installed on the conveyor chain 20. The hydraulic motor 22 is installed on the top of the rear mounting bracket 18. The output end of the hydraulic motor 22 is connected to the input end of the sprocket 19. Multiple stem-pulling plates 5 are evenly installed at the rear end of the stem-pulling roller 2. The stem-pulling plates 5 on the left and right sides are arranged crosswise. Multiple anti-clogging cones 7 are evenly installed on the outer wall of the stem-pulling roller 2. Two guide cones 6 are respectively installed at the front end of the stem-pulling roller 2. Two dividing plates 8 are respectively installed on the left and right sides of the front end of the frame 1. Protrusions 23 are installed on the left and right sides of the inner wall of the frame 1.

[0020] The drive gear 4 is connected to the drive components of the harvester. The two drive gears 4 drive the stalk-pulling roller 2 to rotate. The rotating rod 9 pushes the adjusting slider 10 to move within the adjusting groove, thereby pushing the connecting block 13 through the push frame 11 and adjusting arm 12. This causes the inclined ear-picking plates 15 to move closer or further apart, thus adjusting the spacing between the inclined ear-picking plates 15. This allows for ear-picking work on different varieties and sizes of corn. The adjusting nut 17 facilitates adjustment by using a hexagonal wrench to rotate the rotating rod 9. When the inclined ear-picking plates 15 move, they cause the limiting slide rod 16 to slide within the limiting groove, providing limiting support for the inclined ear-picking plates 15 and increasing their height. The structure is strong, ensuring stability and extending service life. The hydraulic motor 22 drives the sprocket 19 to rotate, which in turn drives the conveyor chain 20 to rotate. The material is moved by the agitator block 21, enabling rapid corn ear picking and improving practicality. The rotating stalk roller 2 pushes the stalk into the space between the stalk pulling plates 5, which pull the stalk down to separate it from the corn ears, thus achieving the function of separating the stalk. The anti-clogging cone tip 7 can effectively tear the stalk, thereby effectively preventing blockage between the two stalk pulling rollers 2. The guide cone head 6 can separate the stalk. During the harvester's movement, the stalk is separated by the drive box 3.

[0021] like Figures 1 to 5 As shown, this utility model discloses an anti-tangle corn harvester ear-picking guide device. During operation, rotating the rotating rod 9 pushes the adjusting slider 10 to move within the adjusting groove, thereby pushing the connecting block 13 through the pushing frame 11 and adjusting arm 12, causing the inclined ear-picking plates 15 to move closer or further apart, thus adjusting the spacing of the inclined ear-picking plates 15. This allows for ear-picking work on corn of different varieties and sizes. During the harvester's movement, the stalks are separated by the drive box 3. The drive gear 4 is connected to the harvester's drive components, and the two drive gears 4 drive the stalk-pulling roller 2 to rotate. The hydraulic motor 22 drives the sprocket 19 to rotate, and the sprocket 19 drives the conveyor chain 20 to rotate. The agitator block 21 moves the material, enabling rapid corn ear picking. The rotation of the stalk-pulling roller 2 pushes the stalk into the space between the stalk-pulling plates 5, which pull the stalk down to separate it from the corn ear, achieving the function of separating the stalk. The anti-clogging cone tip 7 can effectively tear the stalk, thus effectively preventing blockage between the two stalk-pulling rollers 2.

[0022] The hydraulic motor 22 of the anti-tangle corn harvester ear-picking guide device of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
