Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a corn divider that allows for rapid adjustment of row spacing. Background Technology

[0002] As a major grain crop in my country, the level of mechanization in field operations such as sowing, cultivation, and harvesting of corn is of paramount importance. In the mechanized operation of corn, the row divider is a key guiding and row-separating device. Its function is to separate the staggered corn plants into rows in advance, guiding the crop smoothly into subsequent working parts (such as the sowing furrow opener, cultivation shovel, and harvesting support device), thereby avoiding plant congestion, lodging, breakage, or missed harvesting, and ensuring the quality and efficiency of the operation.

[0003] Currently, the corn dividers widely used in agricultural production are mostly one-piece designs, meaning the dividing stalks or spades are welded to the mounting bracket. The row spacing (the lateral distance between two adjacent dividers) is fixed at the factory. This fixed structure has poor adaptability. Corn planting techniques vary across my country, and row spacing specifications differ, commonly including 50cm, 60cm, 65cm, and 70cm. When the row spacing of the work area changes, the existing fixed dividers cannot be directly adapted. Secondly, the adjustment precision of existing corn dividers is low, affecting the quality of operation. Due to the lack of a fast and precise adjustment mechanism, the row spacing adjustment of existing dividers relies heavily on the operator's visual estimation and experience, making it difficult to guarantee the accuracy and consistency of the adjustment. Inaccurate row spacing adjustment can lead to the divider not being accurately aligned with the corn plant row, and during operation, the divider may scrape or squeeze the plant roots, causing crop damage and ultimately affecting the uniformity of sowing, the effectiveness of weeding, or the harvest loss rate.

[0004] Therefore, there is an urgent need in this field for a corn divider technology that can quickly, accurately, and without modification adjust the row spacing, in order to overcome the above-mentioned shortcomings of the existing technology, adapt to various row spacing agronomic requirements, and improve the quality and efficiency of the entire mechanized corn operation. Utility Model Content

[0005] The purpose of this invention is to provide a corn divider that can quickly adjust row spacing. It has the advantages of fast and accurate adjustment, strong adaptability, simple operation and stable and reliable structure, and solves the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A corn divider for quick row spacing adjustment includes a horizontal block, a top block fixed to the upper end of the horizontal block, a first mounting frame and a second mounting frame sleeved on the side wall of the integral structure formed by the horizontal block and the top block, a first corn dividing tip fixed to the end of the first mounting frame away from the top block, a second corn dividing tip fixed to the end of the second mounting frame away from the top block, an arc-shaped supporting rod fixed to the upper end of the second mounting frame, a first fixing block fixed to one end of the horizontal block, graduated grooves evenly distributed on one side of the horizontal block, a moving mechanism on the other side of the horizontal block for moving the second mounting frame, and an angle adjusting mechanism on the first fixing block for adjusting the angle of the first fixing block. A reinforcing block is fixed to the end of the first fixed block away from the angle adjustment mechanism. A second protective block is fixed to the end of the reinforcing block away from the first fixed block. The second protective block is U-shaped and the other end of the second protective block is fixed to the moving mechanism. A pressure detection mechanism is provided on the angle adjustment mechanism. The top block has equally spaced screw holes at its upper end. The first mounting frame is threaded with a first bolt at its upper end. The lower end of the first bolt passes through the upper end of the first mounting frame and is threaded into the inner wall of one of the screw holes. The second mounting frame is threaded with a second bolt at its upper end. The lower end of the second bolt passes through the upper end of the second mounting frame and is threaded into the inner wall of the other screw hole. The other end of the cross block has a screw groove, and the inner wall of the screw groove is threaded with a dividing assembly.

[0007] Preferably, the moving mechanism includes an L-shaped block and a second fixed block fixed to the other side of the cross block, a servo motor fixed to the L-shaped block, a lead screw fixed to the output shaft of the servo motor, and a threaded sleeve block threaded to the side wall of the lead screw. The side wall of the threaded sleeve block and the side wall of the second mounting frame are fixed to each other, and the end of the lead screw away from the servo motor is rotatably mounted in the second fixed block.

[0008] It is worth noting that the moving mechanism is driven by a servo motor to rotate the lead screw, which in turn drives the threaded sleeve and the second mounting frame to move precisely along the cross block. This enables rapid adjustment of the row spacing. The scale groove assists in visual positioning, making the row spacing setting more intuitive and reliable. This design can adapt to different corn planting row spacing requirements, reduce manual adjustment time, and improve the automation level of agricultural machinery. At the same time, the lead screw structure has a self-locking function, which can prevent accidental displacement during operation and enhance the stability and safety of the equipment.

[0009] Preferably, the sidewall of the L-shaped block is fitted with multiple sliding frames, and the sidewall of the sliding frames is fixed with a dustproof rubber strip.

[0010] It is worth noting that the sliding frame and dustproof rubber strip can effectively prevent dust, mud and other debris from entering the moving mechanism, reducing the wear and failure risk of the lead screw. This design can improve the durability of the equipment under harsh field conditions, ensure the long-term reliable operation of the row spacing adjustment mechanism, and reduce the performance degradation of the device caused by pollution.

[0011] Preferably, the angle adjustment mechanism includes a mounting plate hinged to the first fixed block, ear plates fixed to the upper and lower ends of the mounting plate, a controller fixed to the upper end of the mounting plate, and a cylinder hinged to the end of the mounting plate near the first fixed block, wherein the output shaft of the cylinder is hinged to the end of the first fixed block near the mounting plate. It is worth noting that the angle adjustment mechanism uses a cylinder to drive the adjustment of the angle of the first fixed block and the divider, adapting to different terrains and crop growth conditions. The cylinder can provide strong and stable thrust, and combined with the controller, it can achieve automated angle control, improving adjustment accuracy and response speed.

[0012] Preferably, a first protective block is fixed to one side of the mounting plate, and there is a gap between the first protective block and the first fixing block. The cylinder is located in the area enclosed by the first protective block and the ear plate.

[0013] It is worth noting that the first protective block is designed to provide effective protection for the cylinder and hinge point, preventing external impacts or debris from interfering with the movement of the mechanism. Its advantage is that the first protective block is made of sturdy materials, which can withstand collisions and wear during field operations. The reserved gap ensures that the cylinder and components can move freely during adjustment, avoiding interference and jamming.

[0014] Preferably, the pressure detection mechanism includes a third fixing block fixed to one end of the mounting plate near the first fixing block, a rubber cylinder fixed to the side wall of the third fixing block, and a pressure sensor fixed inside the rubber cylinder, with the pressure detection end of the pressure sensor corresponding to the second protective block.

[0015] It is worth noting that the pressure detection mechanism monitors the load changes of the divider in real time through a pressure sensor, realizing overload protection and intelligent adjustment. Its advantage is that the rubber cylinder provides a buffering effect, which can reduce the impact damage to the sensor and ensure the accuracy of the detection data. The pressure sensor is linked with the controller and can automatically stop or adjust the angle in case of abnormal pressure to prevent equipment damage. This design can improve operational safety and avoid mechanical failure due to excessive load.

[0016] Preferably, the dividing assembly includes a first threaded post threaded onto the inner wall of the threaded groove and a tapered head fixed to the end of the first threaded post away from the transverse block.

[0017] It is worth noting that this separating component adopts a conical head design. Its sharp front end can smoothly cut into the rows of corn plants, effectively separating densely growing seedlings. Its advantages lie in the excellent guiding and low resistance characteristics of the conical head, which can smoothly separate intertwined stems and leaves during the process, reducing pulling damage to the plant stems and leaves. The structure is simple, reliable, easy to manufacture and maintain, and can be quickly replaced through threaded connection.

[0018] Preferably, the dividing assembly includes a second threaded post threaded onto the inner wall of the threaded groove, a bent portion fixed to the end of the second threaded post away from the cross block, and a flat shovel portion fixed to the lower end of the bent portion, wherein the bent portion and the flat shovel portion form a Z-shaped structure.

[0019] It is worth noting that the Z-shaped structure of this dividing component, through the combination of the curved part and the flat shovel part, achieves the dual functions of dividing and supporting seedlings. Its advantages are that the curved part can smoothly guide the crop, while the flat shovel part can precisely reach under the fallen seedlings and gently lift them using forward momentum, effectively correcting the lodging phenomenon. The Z-shaped structure provides optimized mechanical leverage to ensure stable and reliable seedling support. This design can significantly reduce harvest losses caused by lodging, improve seedling survival rate and uniformity of later growth, and is particularly suitable for seedling management or field operations after wind and rain, enhancing the comprehensive agronomic value of the dividing device.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a moving mechanism composed of a servo motor, a lead screw, and a threaded sleeve, can drive the second mounting frame and the second corn dividing tip on it to move precisely along the horizontal block. Combined with the manual pre-positioning of the first mounting frame and the visual positioning of the scale groove on the side of the horizontal block, it realizes the rapid and precise adjustment of the row spacing of the divider. This structure effectively overcomes the defect of traditional fixed dividers that cannot adapt to various row spacing agronomic requirements, significantly improves the adaptability of the divider to different planting specifications, and at the same time, the self-locking characteristic of the lead screw drive ensures the stability of the row spacing during operation. 2. By driving the cylinder in the angle adjustment mechanism, the working angle of the first fixed block and the entire divider can be flexibly adjusted, enabling the equipment to better adapt to uneven terrain and crops in different growth stages. In conjunction with the pressure detection mechanism to monitor the workload in real time, the controller can automatically adjust or stop when encountering abnormal resistance. This design not only reduces mechanical damage to corn plants, but also improves the safety and reliability of the equipment under complex working conditions. 3. The dividing component adopts a replaceable modular design, providing two options: a conical head and a Z-shaped structure. These are designed for normal row division and supporting lodged seedlings, respectively. The conical head can smoothly separate interlaced plants, while the combination of the curved part and the flat shovel part of the Z-shaped structure can effectively support lodged seedlings. This multi-functional design expands the application scenarios of the dividing device, significantly improves the quality of operation, and is particularly suitable for seedling management and post-disaster field operations.

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.

[0024] To address the problems of existing technologies where row spacing adjustment requires disassembly and modification, is cumbersome and time-consuming, and suffers from low accuracy due to the lack of precise rulers, leading to poor work quality, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-6 ; A corn divider for quick row spacing adjustment includes a horizontal block 1, a top block 2 fixed to the upper end of the horizontal block 1, a first mounting frame 3 and a second mounting frame 5 sleeved on the side wall of the integral structure formed by the horizontal block 1 and the top block 2, a first corn dividing tip 4 fixed to the end of the first mounting frame 3 away from the top block 2, a second corn dividing tip 501 fixed to the end of the second mounting frame 5 away from the top block 2, an arc-shaped supporting rod 6 fixed to the upper end of the second mounting frame 5, a first fixing block 7 fixed to one end of the horizontal block 1, scale grooves 101 evenly distributed on one side of the horizontal block 1, a moving mechanism 8 on the other side of the horizontal block 1 for moving the second mounting frame 5, and an angle adjusting mechanism 9 on the first fixing block 7 for adjusting the angle of the first fixing block 7. A reinforcing block 10 is fixedly connected to one end of the first fixed block 7 away from the angle adjustment mechanism 9. A second protective block 11 is fixedly connected to one end of the reinforcing block 10 away from the first fixed block 7. The second protective block 11 is U-shaped and its other end is fixedly connected to the moving mechanism 8. A pressure detection mechanism is provided on the angle adjustment mechanism 9. The top block 2 has equally spaced screw holes at its upper end. The first mounting frame 3 has a first bolt 301 threadedly installed at its upper end. The lower end of the first bolt 301 passes through the upper end of the first mounting frame 3 and is threadedly installed on the inner wall of one of the screw holes. The second mounting frame 5 has a second bolt 502 threadedly installed at its upper end.

The other end of the horizontal block 1 is provided with a screw groove 15, and the inner wall of the screw groove 15 is threaded with a dividing assembly.

[0025] In use, the angle adjustment mechanism 9 can be fixed on both sides of the harvester, so that the lower ends of the first corn dividing tip 4 and the second corn dividing tip 501 are above the soil to be divided. Remove the second bolt 502, open the moving mechanism 8 so that the second mounting frame 5 moves along the side wall of the integrated structure formed by the cross block 1 and the top block 2 to a suitable position. Then, manually pass the lower end of the second bolt 502 through the upper end of the second mounting frame 5 and thread it into the inner wall of another screw hole to fix the second mounting frame 5. The distance between the second mounting frame 5 and the first mounting frame 3 can be quickly adjusted to the required distance. When angle adjustment is required, the angle adjustment mechanism 9 can be opened to adjust the angle of the cross block 1. When the second protective block 11 touches the pressure detection mechanism, the maximum angle adjustment stroke can be obtained, which can prevent excessive angle adjustment. The dividing assembly can be used to divide the grain first.

[0026] In this embodiment, specifically: the moving mechanism 8 includes an L-shaped block 801 and a second fixed block 802 fixed to the other side of the horizontal block 1, a servo motor 803 fixed to the L-shaped block 801, a lead screw 804 fixed to the output shaft of the servo motor 803, and a threaded sleeve 807 threadedly installed on the side wall of the lead screw 804. The side wall of the threaded sleeve 807 and the side wall of the second mounting frame 5 are fixed to each other. The end of the lead screw 804 away from the servo motor 803 is rotatably installed in the second fixed block 802.

[0027] In this embodiment, specifically: the side wall of the L-shaped block 801 is fitted with a plurality of sliding frames 805, and the side wall of the sliding frame 805 is fixedly connected with a dustproof rubber strip 806.

[0028] In this embodiment, specifically: the angle adjustment mechanism 9 includes a mounting plate 901 hinged to the first fixed block 7, ear plates 902 respectively fixed to the upper and lower ends of the mounting plate 901, a controller 903 fixed to the upper end of the mounting plate 901, and a cylinder 904 hinged to one end of the mounting plate 901 near the first fixed block 7. The output shaft of the cylinder 904 is hinged to one end of the first fixed block 7 near the mounting plate 901. In this embodiment, specifically: a first protective block 905 is fixedly connected to one side of the mounting plate 901, there is a gap between the first protective block 905 and the first fixing block 7, and the cylinder 904 is located in the area enclosed by the first protective block 905 and the ear plate 902.

[0029] In this embodiment, specifically: the pressure detection mechanism includes a third fixing block 12 fixed to one end of the mounting plate 901 near the first fixing block 7, a rubber cylinder 13 fixed to the side wall of the third fixing block 12, and a pressure sensor 14 fixed inside the rubber cylinder 13. The pressure detection end of the pressure sensor 14 corresponds to the second protective block 11.

[0030] Example 1: In this example, specifically: the separating component includes a first threaded post 16 threaded into the inner wall of the threaded groove 15 and a conical head 17 fixed to the end of the first threaded post 16 away from the horizontal block 1. The conical head 17 is designed to easily and accurately cut into the rows of corn plants, effectively separating the staggered seedlings, reducing forward resistance and pulling damage to the plant stems. Its structure is simple and reliable, easy to manufacture and maintain. The threaded connection between the first threaded post 16 and the threaded groove 15 enables quick installation and replacement. It is suitable for various row spacings and soil conditions, improving the smoothness and efficiency of separating operations, while reducing energy consumption and equipment maintenance costs.

[0031] Example 2: In this example, specifically: the dividing assembly includes a second threaded post 18 threaded into the inner wall of the threaded groove 15, a curved part 19 fixed to the end of the second threaded post 18 away from the horizontal block 1, and a flat shovel part 20 fixed to the lower end of the curved part 19. The curved part 19 and the flat shovel part 20 form a Z-shaped structure. The Z-shaped structure, through the combination of the curved part 19 and the flat shovel part 20, realizes the dual functions of dividing and supporting seedlings. The curved part 19 can smoothly guide the crop to be divided into rows, while the flat shovel part 20 can accurately extend under the fallen seedlings and gently lift them using the forward power of the equipment, effectively correcting the phenomenon of plant lodging. This structure provides optimized mechanical levers to ensure stable and reliable seedling support, significantly reducing harvest losses caused by lodging, improving seedling survival rate and growth uniformity, and is particularly suitable for seedling management or field operations after wind and rain, enhancing the comprehensive agronomic value and adaptability of the dividing device.

[0032] Working principle: When in use, the angle adjustment mechanism 9 is fixed to the harvester frame through the mounting plate 901. The row spacing adjustment method of the divider is as follows: First, determine the target row spacing. Then, by loosening the first bolt 301, manually adjust the first mounting frame 3 to move along the guide rail formed by the cross block 1 and the top block 2 to set a reference position or make a coarse adjustment. Then tighten the first bolt 301 to fix it. Next, remove the second bolt 502, turn on the servo motor 803 in the moving mechanism 8, drive the lead screw 804 to rotate, and drive the threaded sleeve block 807 and the second mounting frame 5 fixed thereto to move along the horizontal block 1. Precise positioning is achieved by observing the scale groove 101 on the side of the horizontal block 1. After the second mounting frame 5 moves to the target position, the servo motor 803 is stopped and locked in the corresponding screw hole of the top block 2 by the second bolt 502. Thus, by adjusting the positions of the first mounting frame 3 and the second mounting frame 5 sequentially or in concert, the working row spacing between the first corn row tip 4 and the second corn row tip 501 can be set quickly and accurately, ensuring the symmetry and adaptability of the corn division operation. When the working angle of the divider needs to be adjusted, the cylinder 904 extends and retracts according to the command of the controller 903, pushing the first fixed block 7 to rotate around the hinge point, thereby driving the horizontal block 1 and the entire divider to make pitch adjustment. At this time, the second protective block 11 rotates synchronously with the horizontal block 1. When it rotates to the limit position, the second protective block 11 contacts the pressure sensor 14, the rubber cylinder 13 deforms and transmits the pressure signal to the controller 903, and the controller 903 immediately stops the cylinder 904 to achieve angle limit protection. During operation, the dividing component first contacts the crop. In Example 1, the conical head 17 can be smoothly inserted into the plant rows to achieve row division. In Example 2, the curved part 19 guides the plant, while the flat shovel part 20 penetrates deep into the base of the seedling to lift up the fallen plant. Then, the first corn dividing tip 4 and the second corn dividing tip 501 accurately divide the crop into rows, and the arc-shaped supporting stalk 6 assists in supporting the plant to ensure that the crop smoothly enters the subsequent operation unit.
