Description

Technical Field

[0001] The invention belongs to the field of corn harvesters, and in particular relates to a corn peeling device and a corn harvester. Background Art

[0002] Agronomic issues with corn primarily manifest in significant variations in harvest conditions and moisture content across regions and varieties. A prominent issue is the need to balance corn harvesting with the wheat-corn rotation in the Huanghuai and Haihe regions, necessitating a timely harvest. Consequently, corn harvest is generally advanced to allow time for wheat planting. Consequently, corn in these regions is typically harvested relatively green and at the waxy stage, resulting in higher moisture content. This also means that the moisture content of the cobs and husks is high, and the husks are tightly closed. Using a flat roller peeling mechanism, due to its low peeling strength, can result in incomplete husk removal, impacting the performance of mechanized corn harvesting. Inadequate performance can impact customer satisfaction. However, using a high-low roller peeling mechanism offers superior harvesting results, significantly improving the clean husk removal rate. However, in the single-season corn planting areas in the northwest and northeast regions of the north, the harvest period is generally at the mature stage. At this time, the corn is basically mature, the connection between the corn kernels and the corn cobs becomes weak, and the husk mouth is loose. When the high-low roller structure is used for peeling, the kernels are easily dropped and damaged due to the high peeling strength, resulting in losses. Since the moisture content of the corn plants is low at this time, the flat roller peeling structure has a better harvesting effect. Not only does it not damage the kernels in the cob, but the cob peeling rate can also meet the performance requirements. At present, corn harvesters are more and more operating across regions. The rocker arm corresponding to the floating roller of the current corn peeling device has two mounting holes. The high-low roller state is assembled in the lower mounting hole of the rocker arm, and the flat roller state is assembled in the upper mounting hole of the rocker arm. However, in actual operation, the corn peeling device needs to be removed from the whole machine and adjusted on the adjustment platform. The adjustment takes a long time (one day) and is expensive (delaying the user's harvesting operation). Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a corn peeling device with a simple structure and flexible adjustment of the height of the floating peeling roller.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a corn peeling device, comprising a fixed roller mounting frame, a floating roller mounting frame and multiple groups of peeling roller groups, the multiple groups of peeling roller groups are spaced apart along the left and right directions, each group of the peeling roller groups comprises a floating peeling roller and a fixed peeling roller horizontally arranged along the front and back directions, both ends of each of the floating peeling rollers are connected to the floating roller mounting frame, and both ends of each of the fixed peeling rollers are connected to the fixed roller mounting frame, and the floating roller mounting frame can move up and down relative to the fixed roller mounting frame to drive the floating peeling roller to move up and down relative to the fixed peeling roller.

DETAILED DESCRIPTION

[0039] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] Example 1

[0041] like Figure 1 and Figure 2As shown, this embodiment provides a corn peeling device, including a fixed roller mounting frame 1, a floating roller mounting frame 2 and multiple groups of peeling roller groups 3, the fixed roller mounting frame 1 has two fixed plates 11, the two fixed plates 11 are horizontally arranged in the left and right directions, and are spaced apart in the front and back directions, the floating roller mounting frame 2 has two floating plates 21 horizontally arranged in the left and right directions, and the two floating plates 21 correspond to the two fixed plates 11 one by one, each floating plate 21 is close to the corresponding fixed plate 11, the multiple groups of peeling roller groups 3 are spaced apart in the left and right directions, and each group of peeling roller groups 3 includes a floating peeling roller 31 and a fixed peeling roller 32 arranged horizontally along the front-to-back direction. The two ends of each floating peeling roller 31 are connected to the two floating plates 21, and the two ends of each fixed peeling roller 32 are connected to the fixed plate 11. The floating roller mounting frame 2 can move up and down relative to the fixed roller mounting frame 1 to drive the floating peeling roller 31 to move up and down relative to the fixed peeling roller 32. In this way, the height of the floating peeling roller can be adjusted as a whole by adjusting the horizontal height of the floating roller mounting frame, so that the corn peeling device can flexibly adapt to the peeling process of corn in different areas. Of course, each floating plate can be slidably connected to the corresponding fixed plate (the floating plate can slide up and down relative to the fixed plate, such as Figure 2 As shown, two floating plates can be placed between two fixed plates, or as Figure 1 As shown, two fixed plates are arranged between two floating plates).

[0042] The fixed roller mounting frame 1 in the above technical solution further includes a first connecting plate 12, which is disposed between the two fixed plates 11, and whose ends are connected to the two fixed plates 11. This allows the two fixed plates to be connected and fixed via the first connecting plate, thereby facilitating installation. Two first connecting plates may be provided, and the two first connecting plates and the two fixed plates together form a "mouth" shape.

[0043] See Figure 13 and Figure 14 In the above technical solution, the floating roller mounting frame 2 further includes a second connecting plate 22, which is disposed between the two floating plates 21, with both ends of the second connecting plate 22 connected to the two floating plates 21. Two second connecting plates 22 may be provided, and the two second connecting plates may, together with the two floating plates, form a "mouth" shape. Alternatively, the two second connecting plates may be arranged in an "X" shape between the two floating plates. This allows the two floating plates to be connected and fixed via the second connecting plates, making installation more convenient.

[0044] like Figure 8-10As shown, in the above technical solution, each floating plate 21 is spaced apart from the corresponding fixed plate 11 along the front-to-back direction, with a gap therebetween. An anti-jamming member 4 is disposed within the gap. Alternatively, multiple anti-jamming members may be disposed within the gap along the left-to-right direction. This anti-jamming member maintains a constant gap between the fixed and floating plates, preventing jamming between the floating and fixed plates due to corrosion and adhesion. Preferably, the anti-jamming member 4 is a boss, ball, or roller mounted on the floating plate 21 or fixed plate 11 (the roller's axle being horizontally disposed in the left-to-right direction). This simple structure prevents jamming between the floating and fixed plates while also reducing frictional resistance between them.

[0045] The above technical solution also includes an adjusting device 5, and the floating roller mounting frame 2 is installed on the fuselage or the fixed roller mounting frame 1 through the adjusting device 5. The adjusting device 5 is used to adjust the height of the floating roller mounting frame 2 relative to the fixed roller mounting frame 1, so that the height of the floating roller mounting frame relative to the fixed roller mounting frame 1 can be conveniently adjusted through the adjusting device.

[0046] The adjusting device 5 in the above technical solution is a telescopic member (telescopic electric cylinder, telescopic air cylinder or hydraulic cylinder) or a lifting member (which can be a manual or electric screw lifter, or a jack), which makes it easier to adjust the height of the floating roller mounting frame.

[0047] Wherein, the said adjustment device can be provided with one or more, and when the adjustment device is a telescopic member, for example, the adjustment device can be provided with four, two or one. Figure 11 and Figure 12 As shown, when there are four adjusting devices, that is, each end of each floating plate is provided with an adjusting device (the installation method is not limited to this), and the telescopic ends of the four adjusting devices are all facing upward or downward and connected to the end of the corresponding floating plate close to it, the four adjusting devices are synchronously telescoped to jointly adjust the floating roller mounting frame to move up and down; Figure 13 As shown, when there are two adjusting devices, the two adjusting devices can correspond to the two floating plates one by one, and the telescopic end of each adjusting device is either facing upward or downward, and is connected to the middle portion corresponding to the length direction of the corresponding floating plate (the installation method is not limited to this), and the telescopic ends of the two adjusting devices are synchronously extended and retracted to drive the floating roller mounting frame to move up and down (and when there are two second connecting plates and the floating roller mounting frame is in the shape of a "mouth", the telescopic ends of the two adjusting devices can either face upward or downward, and are respectively connected to the middle portions of the two second connecting plates, and the telescopic ends of the two adjusting devices are synchronously extended and retracted to drive the floating roller mounting frame to move up and down); as shown Figure 14As shown, when there is one adjusting device, two second connecting plates can be set at this time, and the two second connecting plates are cross-connected in an "X" shape between the two floating plates, and the telescopic end of the adjusting device is facing upward and connected to the intersection of the two second connecting plates. Of course, one second connecting plate can also be set at this time. At this time, the second connecting plate and the two floating plates are in an "H" shape, and the telescopic end of the adjusting device is facing upward and connected to the middle part of the second connecting plate. At this time, the adjusting device is telescopic to drive the floating roller mounting frame to move up and down.

[0048] Of course, if Figure 15 As shown, the adjusting device 5 can also include two bolts 51, and each fixed plate can correspond to multiple adjusting devices. A plurality of connecting ear groups are provided on the fixed plate close to the side corresponding to the floating plate along its length direction, and each connecting ear group has two connecting ears 111 spaced apart and located on the upper and lower sides of the corresponding floating plate. The number of adjusting devices on each fixed plate corresponds one to one to the number of connecting ear groups thereon, and the two connecting ears of the same group are provided with screw holes passing through the upper and lower parts. The two bolts corresponding to each adjusting device are respectively threadedly connected to the screw holes on the corresponding two connecting ears, and the threaded ends of the two bolts corresponding to each adjusting device are close to each other and clamp the floating plate between the two (the bolts above the multiple adjusting devices are loosened, and the bolts below are tightened to make the floating plate move upward, and the bolts below the multiple adjusting devices are loosened, and the bolts above are tightened to make the floating plate move downward).

[0049] Among them, such as Figure 3-Figure 6 As shown, each of the peeling roller groups 3 includes two floating peeling rollers 31, two fixed peeling rollers 32 and two damping members 33;

[0050] The two floating peeling rollers 31 of the same group are spaced apart in the left-right direction, and the two fixed peeling rollers 32 of the same group are also spaced apart in the left-right direction and located between the two floating peeling rollers 31 of the same group; a vertically arranged rocker arm 34 is rotatably mounted at each end of each floating peeling roller 31, the upper end of the rocker arm 34 is rotatably connected to the corresponding end of the corresponding floating peeling roller 31, and the middle portion of the rocker arm 34 in the corresponding length direction is connected to the floating plate 21 on the same side for left and right swinging;

[0051] The two damping members of the same group are horizontally arranged in the left-right direction and spaced apart in the front-back direction, and the lower ends of the two rocker arms 34 on the same side in the same group are respectively connected to the two ends of the corresponding damping members 33 on the same side for swinging. The damping members 33 are used to drive the corresponding two rocker arms 34 to swing to their lower ends away from each other, and the two damping members 33 of the same group are used to drive the corresponding four rocker arms 34 to swing to the corresponding two floating peeling rollers 31 to press on the two fixed peeling rollers 32 of the same group. By arranging the rocker arms 34 and the damping members 33, the rocker arms 34 are always pressed downward by the action of the damping members 33 to fit the corresponding two fixed peeling rollers 32.

[0052] In addition, the height of the floating roller mounting frame 2 can be flexibly adjusted relative to the fixed roller mounting frame 1 (the height difference between the two can be adjusted steplessly or in steps within a certain range).

[0053] Among them, such as Figure 7 As shown, the damping member 33 includes a slide rod 331 and a spring 332. The slide rod is horizontally arranged in the left and right directions, and the slide rod is connected to the lower ends of the corresponding two rocker arms for sliding and swinging (the lower end of the rocker arm 34 is vertically provided with left and right waist-circular holes, and the slide rod passes through the waist-circular holes, and the waist-circular holes provide space for the rocker arm 34 to swing left and right), and the ends of both ends of the slide rod are respectively provided with limit blocks for limiting the rocker arm from sliding down. The spring is sleeved on the slide rod, and its two ends are respectively abutted or connected to the lower ends of the two rocker arms. The spring is used to drive the lower ends of the corresponding two rocker arms to swing away from each other. Its structure is simple, and the elastic force of the spring drives the lower ends of the two rocker arms to move away from each other on the slide rod.

[0054] In the above technical solution, the peeling roller group 3 is provided with 4-7 groups, which makes the peeling effect better.

[0056] This embodiment provides a corn harvester, including the corn peeling assembly as described in Example 1, so that the height of the floating peeling roller of the corn harvester can be easily adjusted, which is particularly suitable for cross-regional operations.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
