Description

Technical Field

[0001] This utility model relates to the field of corn harvester technology, and in particular to a corn peeling device with adjustable trough roller. Background Technology

[0002] As one of my country's main grain crops, the hulling process in mechanized corn harvesting is crucial. The performance of the corn hulling machine directly affects the harvest quality. Improper clamping force and angle of the hulling rollers can easily lead to kernel loss or incomplete hulling. Currently, corn moisture content varies significantly depending on the planting region and variety: corn kernels with high moisture content are softer, requiring less clamping force and a smaller hulling angle to avoid kernel loss; corn kernels with low moisture content are harder, requiring a larger angle to improve hulling efficiency.

[0003] Chinese Patent Application Publication No. CN116326338A discloses a corn peeling mechanism, including a mounting frame, a drive rod, an adjustment mechanism, and peeling components. The drive rod is rotatably mounted on the mounting frame. Several peeling components are arranged on the mounting frame, and the drive rod is connected to the peeling components. A movable frame is slidably mounted at each end of the mounting frame. The adjustment mechanism is located at the side end of the mounting frame and is connected to the movable frames on both sides. The peeling components include a first peeling roller, a second peeling roller, a third peeling roller, and a fourth peeling roller, which are arranged sequentially. The first and fourth peeling rollers are rotatably mounted on the movable frame, and the second and third peeling rollers are rotatably mounted on the mounting frame.

[0004] Although the aforementioned existing technology can adjust the peeling component through an adjustment mechanism, it still has the following shortcomings in actual use: First, the adjustment mechanism uses a gear and rack transmission, which requires precise matching. Long-term use can easily lead to wear and gaps, resulting in a decrease in adjustment accuracy. In addition, the two movable frames rely on a long-handled linkage rod for synchronization, making synchronization control difficult. Second, the movable frame and the mounting frame are fixed by oblong holes and bolts, requiring manual locking after adjustment, which is cumbersome. Furthermore, the bolt connection is susceptible to loosening due to vibration. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing corn peeling machines, such as complex adjustment mechanism structure, easy wear, complicated operation, and poor stability, and to provide a corn peeling device with adjustable groove roller.

[0006] This utility model is achieved through the following technical solution: a grooved roller adjustable corn peeling device includes a frame and several peeling roller groups. Corresponding floating plates are movably arranged on both inner sides of the frame, and a connecting rod is provided between two floating plates. The two ends of the connecting rod are movably connected to the floating plates via pins A. Several peeling roller groups are arranged between the two floating plates, and each peeling roller group includes a spiral roller and a fish-scale roller. The two ends of the spiral roller movably pass through the floating plates and are connected to the frame, while the two ends of the fish-scale roller are connected to the floating plates. One floating plate is connected to an adjustment mechanism A mounted on the frame, and the other floating plate is connected to an adjustment mechanism B mounted on the frame. The adjustment mechanisms A and B are linked and cooperate with their respective connected floating plates, driving the floating plates to slide up and down inside the frame, thereby adjusting the height of the fish-scale roller.

[0007] The device has two floating plates inside the frame, which are connected by a connecting rod and pin A to form a linkage. The spiral roller in the peeling roller group is fixed to the frame at both ends, and the fish scale roller is connected to the floating plates at both ends. Adjustment mechanism A and adjustment mechanism B drive the floating plates on both sides to slide up and down, change the height of the fish scale roller, and thus adjust the relative angle and spacing between the spiral roller and the fish scale roller.

[0008] A further improvement of this utility model is that the adjustment mechanism A includes two rocker arms A, which are respectively disposed at both ends of the floating plate. The middle part of the rocker arm A is rotatably connected to the frame through a pin B, thereby forming a lever structure with the pin B as the fulcrum. One end of the rocker arm A is rotatably connected to the bottom of the floating plate through the pin B, and the other end of the rocker arm A extends to the outside of the frame to form an operating end. By rotating the operating end of the rocker arm A, the floating plate can be driven to rise and fall.

[0009] A further improvement of this utility model is that the adjusting mechanism B includes a rocker arm B, which is disposed at one end of the floating plate and located on the outside of the frame. The middle part of the rocker arm B is rotatably connected to the frame through a pin B, thereby forming a lever structure that can rotate around the pin B. One end of the rocker arm B is connected to a rotating arm mechanism located below the floating plate. The rotating arm mechanism is connected to the floating plate. The other end of the rocker arm B forms an operating end, and the floating plate can be driven to rise and fall by rotating the operating end of the rocker arm B.

[0010] A further improvement of this utility model is that the rotating arm mechanism includes a rotating shaft and a rotating arm. The rotating shaft is movably disposed below the floating plate and is connected to a plurality of rotating arms arranged at intervals. One end of the rotating arm is rotatably connected to the bottom of the floating plate, and the other end of the rotating arm is rotatably connected to the rotating shaft. One end of the rotating shaft extends to the outside of the frame and is rotatably connected to the non-operating end of the rocker arm B.

[0011] A further improvement of this utility model is that a single bearing seat is provided at each end of the fish scale roller, and a boss for connecting the single bearing seat is movably provided on the frame. The upper part of the single bearing seat is rotatably connected to the end of the fish scale roller, and the middle part of the single bearing seat is connected to the boss through a pin sleeve. One end of the pin sleeve is rotatably connected to the boss, and the other end of the pin sleeve is rotatably connected to the single bearing seat.

[0012] A further improvement of this utility model is that the frame is provided with an elongated oval sliding groove hole corresponding to the boss, and the boss is movably disposed inside the elongated oval sliding groove hole.

[0013] A further improvement of this utility model is that the outer surface of the spiral roller is provided with spiral ridges, and the outer surface of the fish scale roller is a smooth plane, wherein the spiral roller is used to grip the corn husks, and the fish scale roller is used to squeeze and peel off the corn husks.

[0014] A further improvement of this utility model is that a plurality of rolling steel balls are embedded on the contact surface between the floating plate and the frame, and the steel balls are evenly distributed at both ends and the middle position of the floating plate.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0016] 1. This utility model adopts a lever-type adjustment mechanism to replace the traditional gear and rack transmission, avoiding the wear and clearance problems caused by precision gear matching. The adjustment process only requires rotating the rocker arm to realize the individual or synchronous lifting of the floating plates on both sides, which is labor-saving and highly accurate. The floating plates and the frame are guided by rolling steel balls and elongated sliding groove holes, eliminating the need for manual bolt tightening. Stability is maintained by mechanical limit, which solves the problem of bolt connection being easily loosened by vibration in the prior art, and significantly reduces the complexity of operation and maintenance costs.

[0017] 2. This utility model utilizes a specialized design that separates the functions of the spiral roller and the fish-scale roller. The spiral ridges can efficiently grip the corn husks, while the smooth surface can precisely squeeze and peel them, forming a collaborative working mode of "gripping-peeling". For corn with high moisture content, the clamping force can be reduced by lowering the height of the fish-scale roller to prevent the kernels from falling off. For corn with low moisture content, the fish-scale roller can be raised to increase the peeling angle and improve the efficiency of husk peeling.

[0018] 3. The floating plates on both sides of this utility model form a rigid linkage whole through connecting rods and pins. Combined with the lever transmission of the adjustment mechanism, the error during the lifting and lowering of the floating plates is reduced, avoiding damage to the corn or incomplete peeling due to uneven force. The rotating arm mechanism and the multi-point hinge design evenly transmit the adjustment force to the floating plates. Combined with the rolling friction reduction effect of the steel balls, the sliding resistance of the floating plates is greatly reduced, and the stability of the movement is significantly improved, which can meet the continuous adjustment requirements under high-speed harvesting conditions.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] Please refer to the attached document. Figure 1The following is a description of a specific embodiment: The adjustable corn peeling device of this utility model, combined with an existing corn peeling machine, includes a frame 1 and several peeling roller groups 4. Two corresponding floating plates 2 are movably arranged on the inner sides of the frame 1, one floating plate 2 being closer to the water tank and the other floating plate 2 being closer to the grain bin. A connecting rod 9 is provided between the two floating plates 2, and both ends of the connecting rod 9 are movably connected to the floating plate 2 via pins A10. Several peeling roller groups 4 are arranged between the two floating plates 2. 4 includes a spiral roller 13 and a fish-scale roller 14; the two ends of the spiral roller 13 are respectively connected to the frame 1 after passing through the floating plate 2, and the two ends of the fish-scale roller 14 are respectively connected to the floating plate 2; the floating plate 2 near the grain silo is connected to an adjustment mechanism A3 set on the frame 1, and the floating plate 2 near the water tank is connected to an adjustment mechanism B301 set on the frame 1. The adjustment mechanism A3 and the adjustment mechanism B301 are respectively linked and cooperate with the floating plate 2 connected to them, which can drive the floating plate 2 to slide up and down inside the frame 1, thereby adjusting the height of the fish-scale roller 14.

[0029] Two floating plates 2 are installed inside the frame 1 of this device, which are movably connected by connecting rod 9 and pin A10 to form a linkage; the spiral roller 13 in the peeling roller group 4 is fixed at both ends to the frame 1, and the fish scale roller 14 is connected to the floating plates 2 at both ends; the adjusting mechanism A3 and the adjusting mechanism B301 drive the floating plates 2 on both sides to slide up and down, change the height of the fish scale roller 14, and thus adjust the relative angle and distance between the spiral roller 13 and the fish scale roller 14.

[0030] This device adjusts the height of the fish-scale roller 14 via a linkage with the floating plate 2, adapting to the peeling requirements of corn with different moisture contents: for corn with high moisture content (soft kernels), the height of the fish-scale roller 14 is lowered to reduce the clamping force and peeling angle, avoiding kernel detachment; for corn with low moisture content (hard kernels), the fish-scale roller 14 is raised to form a larger peeling angle, improving the efficiency of husk removal, thus effectively solving the problems of cumbersome adjustment and poor adaptability of traditional mechanisms.

[0031] For details, please refer to the appendix. Figure 2 and 3 The adjustment mechanism A3 includes two rocker arms A7, which are respectively disposed at both ends of the floating plate 2. The middle part of the rocker arm A7 is rotatably connected to the frame 1 through a pin B16, thereby forming a lever structure with the pin B16 as the fulcrum. One end of the rocker arm A7 is rotatably connected to the bottom of the floating plate 2 through the pin B16, and the other end of the rocker arm A7 extends to the outside of the frame 1 to form an operating end. By rotating the operating end of the rocker arm A7, the floating plate 2 can be driven to rise and fall.

[0032] The rocker arm A7 of the adjustment mechanism A3 of this device is fixed to the frame 1 by a pin B16 to form a lever fulcrum. One end is hinged to the bottom of the floating plate 2, and the other end extends to the outside of the frame as the operating end. When the operating end is rotated, the rocker arm A7 rotates around the fulcrum, and drives the floating plate 2 to rise and fall vertically through the lever principle.

[0033] This lever-type transmission structure is simple and reliable. Compared with traditional gear and rack transmission, it avoids gear wear and backlash issues, and offers higher adjustment precision. The two rocker arms A7 synchronously drive both ends of the floating plate 2, ensuring the smooth lifting and lowering of the fish scale roller 14. This solves the problem of poor synchronization in traditional linkage rods and improves adjustment stability. At the same time, the specific design of the adjustment mechanism A3 described above can better adapt to the actual installation space between the floating plate 2 and the frame 1 and grain bin.

[0034] For details, please refer to the appendix. Figure 4 The adjusting mechanism B301 includes a rocker arm B17, which is located at one end of the floating plate 2 and outside the frame 1. The middle part of the rocker arm B17 is rotatably connected to the frame 1 through a pin B16, thereby forming a lever structure that can rotate around the pin B16. One end of the rocker arm B17 is connected to a rotating arm mechanism 8 located below the floating plate 2. The rotating arm mechanism 8 is connected to the floating plate 2. The other end of the rocker arm B17 forms an operating end. By rotating the operating end of the rocker arm B17, the floating plate 2 can be driven to rise and fall.

[0035] The rocker arm B17 of the adjustment mechanism B301 described in this device is hinged to the frame 1 at the middle. One end is connected to the rotating arm mechanism 8 below the floating plate 2, and the other end serves as the operating end. When the operating end is rotated, the rocker arm B17 rotates around the fulcrum, and the rotational motion is converted into the lifting motion of the floating plate 2 through the rotating arm mechanism 8.

[0036] This design allows for differentiated adjustment mechanisms (rocker arm A7 and rocker arm B17 working together) for floating plates 2 at different positions, enabling independent or synchronous adjustment of single or double floating plates 2. It adapts to precise angle adjustments under complex working conditions and offers greater adjustment flexibility compared to traditional single-drive methods, meeting diverse peeling needs.

[0037] For details, please refer to the appendix. Figure 5 The rotating arm mechanism 8 includes a rotating shaft 801 and a rotating arm 802. The rotating shaft 801 is movably disposed below the floating plate 2 and is connected to a number of rotating arms 802 arranged at intervals. One end of the rotating arm 802 is rotatably connected to the bottom of the floating plate 2, and the other end of the rotating arm 802 is rotatably connected to the rotating shaft 801. One end of the rotating shaft 801 extends to the outside of the frame 1 and is rotatably connected to the non-operating end of the rocker arm B17.

[0038] The rotating shaft 801 of the rotating arm mechanism 8 of this device is horizontally arranged below the floating plate 2 and is hinged to the bottom of the floating plate through multiple rotating arms 802; when the rocker arm B17 drives the rotating shaft 801 to rotate, the rotating arms 802 swing around the rotating shaft and push the floating plate 2 to slide up and down along the inner side of the frame 1.

[0039] This multi-point connection structure of the rotating arm 802 evenly transmits the rotational force of the rocker arm B17 to the floating plate 2, avoiding tilting or jamming caused by single-point force and improving the stability of the adjustment process. At the same time, the mechanism occupies little space, is suitable for compact peeling machine design, optimizes equipment layout, and is more conducive to adapting to the actual installation space between the floating plate 2 and the frame 1 and water tank, preventing component interference problems.

[0040] For details, please refer to the appendix. Figure 1 and 4 In conjunction with existing corn peeling machines, the outer surface of the spiral roller 13 is provided with spiral ridges, and the outer surface of the fish scale roller 14 is a smooth plane. The spiral roller 13 is used to grab the corn husks, and the fish scale roller 14 is used to squeeze and peel the corn husks.

[0041] The spiral ridges on the surface of the spiral roller 13 of this device grip the corn husks when rotating and roll them into the spiral gap; the smooth surface of the fish scale roller 14 cooperates with the spiral roller to peel off the husks through squeezing and friction, and the two form a "gripping-peeling" functional combination.

[0042] This design clearly distinguishes the specific functions of the grooved roller (spiral roller 13) and the flat roller (fish scale roller 14): the spiral ridges enhance the gripping force on the husks and prevent slippage; the smooth surface reduces the squeezing damage to the corn kernels, making it especially suitable for protecting corn with high moisture content.

[0043] For details, please refer to the appendix. Figure 2 Several rolling steel balls 11 are embedded on the contact surface between the floating plate 2 and the frame 1. The steel balls 11 are evenly distributed at both ends and the middle of the floating plate 2.

[0044] The contact surface between the floating plate 2 and the frame 1 of this device is embedded with steel balls 11. The steel balls roll as the floating plate rises and falls, converting sliding friction into rolling friction. This rolling friction design of the steel balls 11 significantly reduces the sliding resistance of the floating plate 2, making the adjustment operation easier and reducing wear on the contact surface, thus extending the service life of the equipment. The steel balls 11 are evenly distributed at both ends and in the middle, ensuring that the floating plate 2 is subjected to balanced force, further improving the stability and reliability of the adjustment process.

[0045] In one embodiment, refer to the appendix Figure 6The fish scale roller 14 is provided with single bearing seats 5 at both ends. The frame 1 is movably provided with a boss 15 for connecting the single bearing seats 5. The upper part of the single bearing seat 5 is rotatably connected to the end of the fish scale roller 14. The middle part of the single bearing seat 5 is connected to the boss 15 through a pin sleeve 6 and a bolt. One end of the pin sleeve 6 is rotatably connected to the boss 15, and the other end of the pin sleeve 6 is rotatably connected to the single bearing seat 5.

[0046] The single bearing seats 5 at both ends of the fish scale roller 14 in this device are connected to the boss 15 of the frame 1 through pin sleeves 6: one end of the pin sleeve 6 is rotatably connected to the boss 15, and the other end is rotatably connected to the single bearing seat 5, so that the fish scale roller 14 can both rise and fall with the floating plate 2 and rotate independently.

[0047] This multi-layer rotating connection structure (boss 15, pin sleeve 6 and single bearing seat 5) ensures that the fish scale roller 14 can rotate flexibly when adjusting the height, avoiding the rotational resistance caused by the rigid connection with the floating plate 2; at the same time, the hinged design of the pin sleeve 6 allows the fish scale roller 14 to adapt to the corn diameter within a certain range, improving the fit and stability of the peeling process.

[0048] In one embodiment, refer to the appendix Figure 6 The frame 1 has an elongated oval slide hole 12 corresponding to the boss 15, and the boss 15 is movably disposed inside the elongated oval slide hole 12.

[0049] The oblong groove hole 12 on the frame 1 of this device cooperates with the boss 15 of the floating plate 2. When the boss 15 slides in the groove hole, it limits the movement trajectory of the floating plate 2 to the vertical direction, preventing lateral deviation during the adjustment process.

[0050] The guide structure of the groove hole and the boss 15 provides the floating plate 2 with a precise movement trajectory. Compared with the traditional oval hole bolt positioning, it can maintain stability without manual tightening, simplifying the operation process. At the same time, the oval design allows the floating plate 2 to tilt slightly to adapt to the angle deviation during the corn conveying process and improve the peeling consistency.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
