Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of lifting mechanism technology, and more specifically, to a lifting mechanism for a corn returning machine. Background Technology

[0002] The corn stalk return machine is an important agricultural machinery. The cutting blades on the machine move at high speed to cut and crush the corn stalks on the ground. After repeated cutting and crushing, the stalks are broken into fragments or fibers and then evenly scattered on the ground.

[0003] On some small corn return machines, the cutting blades are usually fixedly installed on the cutter shaft. However, this method is suitable for relatively flat farmland. Some farmland may have uneven terrain, ditches, and field ridges. When the return machine encounters uneven terrain, it needs to raise or lower the blades. However, this small corn return machine is difficult to raise or lower the blades. Therefore, we propose a lifting mechanism for corn return machines. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a lifting mechanism for a corn returning machine, which solves the technical problem that some small corn returning machines in the prior art have difficulty lifting the cutters when encountering uneven terrain.

[0005] According to one aspect, at least one embodiment of this disclosure provides a lifting mechanism for a corn threshing machine, including a mounting frame for mounting the lifting mechanism on the corn threshing machine, and further including a height adjustment component, a connecting frame, an angle adjustment component, a rotating ring, and a rotating component. The height adjustment component is disposed on the mounting frame for adjusting the height of the cutter. The connecting frame is disposed on the height adjustment component. The angle adjustment component is disposed on the connecting frame for rotating the cutter up and down to precisely adjust the height. The rotating ring is disposed on the angle adjustment component. The rotating component is disposed on the angle adjustment component for rotating the cutter.

[0006] Furthermore, the height adjustment assembly includes a support cover, a drive screw, a slide rod, and a motor. Two support covers are provided, both of which are fixedly installed on the side of the mounting bracket. The drive screw is rotatably installed inside one of the support covers, and the slide rod is fixedly installed inside the other support cover. One end of the connecting bracket is threaded to the drive screw, and the other end of the connecting bracket is slidably installed on the slide rod. The motor is installed at the top of the support cover, and the output end of the motor is coaxially connected to the drive screw.

[0007] Furthermore, the angle adjustment assembly includes a mounting plate, a rotating shaft, a rotating rod, and a drive assembly. Two mounting plates are provided, and both mounting plates are fixedly mounted on the side of the connecting frame. The rotating shaft is rotatably mounted between the two mounting plates. Two rotating rods are provided, and both rotating rods are fixedly mounted on the rotating shaft. The rotating ring is fixedly mounted between the two rotating rods. The drive assembly is located on the connecting frame.

[0008] Furthermore, the drive assembly includes a second motor, drive wheels, and a transmission belt. The second motor is mounted on the side of the connecting frame. There are two drive wheels, one of which is fixedly mounted on the rotating shaft, and the other drive wheel is fixedly mounted on the output end of the second motor. The transmission belt is tensioned and sleeved on the two drive wheels.

[0009] Furthermore, the rotating assembly includes a fixed plate, a rotating plate, and a motor. The fixed plate is fixedly installed between the two rotating rods. A circular groove is provided on the inner side wall of the rotating ring. The rotating plate is slidably installed in the circular groove of the rotating ring. The motor is installed on the fixed plate, and the output end of the motor is fixedly connected to the side of the rotating plate.

[0010] Furthermore, it also includes a limiting component, of which two are provided. The limiting component includes an electric cylinder and a limiting block. The electric cylinder is installed on the side of the fixed plate, and the limiting block is fixedly installed on the output end of the electric cylinder.

[0011] Furthermore, a protective cover is detachably installed on the side of the fixing plate, and both the electric cylinder one and the motor three are located inside the protective cover.

[0012] Furthermore, the rotating plate has two limiting holes on its side, and the limiting holes are adapted to the limiting block.

[0013] Furthermore, the connecting frame extends through the transmission belt.

[0014] Furthermore, a mounting rod is fixedly installed on the side of the rotating plate.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, when raising and lowering the blades on the corn returning machine, the blades are mounted on a mounting rod. The height adjustment component allows for significant raising and lowering of the blades, and the angle adjustment component allows for vertical rotation of the blades. By adjusting the angle of the blades, the height of the blades can be changed slightly. This allows for adjustment of the blades when traversing field ridges and slopes of varying heights. Finally, the rotating component allows for left and right rotation adjustment of the blades. If the slope of the field ridge is inclined, the blades can be adjusted to an inclined position to pass over the ridge. Through the cooperation of the height adjustment component, connecting frame, angle adjustment component, rotating ring, and rotating component, this mechanism can adjust the height of the blades, preventing obstruction when traversing uneven farmland.

Detailed Implementation

[0019] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0020] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0022] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Example 1: like Figures 1-5As shown, a lifting mechanism for a corn threshing machine according to an embodiment of this disclosure is illustrated. The mechanism includes a mounting frame 1 for mounting the lifting mechanism onto the corn threshing machine. It also includes a height adjustment component, a connecting frame 2, an angle adjustment component, a rotating ring 3, and a rotating component. The height adjustment component is mounted on the mounting frame 1 and is used to adjust the height of the cutting tool. The connecting frame 2 is mounted on the height adjustment component. The angle adjustment component is mounted on the connecting frame 2 and is used to rotate the cutting tool up and down to precisely adjust the height. The rotating ring 3 is mounted on the angle adjustment component, and the rotating component is mounted on the angle adjustment component to rotate the cutting tool. It should be noted that the bottom end of the mounting rod 20 is lower than the bottom end of the rotating ring 3.

[0026] During installation, the mechanism can be moved by mounting it on the vehicle body via the mounting bracket 1, and the mounting rod 20 is fixedly mounted on the side of the rotating plate 15. The blade can be mounted on the mounting rod 20, thereby driving the blade to grind the corn stalks.

[0027] In some examples, such as Figure 2 As shown, the height adjustment assembly includes a support cover 4, a drive screw 5, a slide rod 6, and a motor 7. There are two support covers 4, both of which are fixedly installed on the side of the mounting bracket 1. The drive screw 5 is rotatably installed inside one of the support covers 4, and the slide rod 6 is fixedly installed inside the other support cover 4. One end of the connecting bracket 2 is threaded to the drive screw 5, and the other end of the connecting bracket 2 is slidably installed on the slide rod 6. The motor 7 is installed on the top of the support cover 4, and the output end of the motor 7 is coaxially connected to the drive screw 5.

[0028] Specifically, when adjusting the height of the cutting tool, the motor 7 is started. The output of the motor 7 drives the drive screw 5 to rotate inside the support cover 4, which in turn drives the connecting frame 2 to move up and down on the slide rod 6 and the drive screw 5. This causes the angle adjustment component and the rotation component to move up and down, thereby adjusting the height of the cutting tool mounted on the mounting rod 20. The cutting tool adjustment component can adjust the height of the cutting tool over a wide range. In some farmland with high ridges, the height adjustment component can be used to adjust the cutting tool over a wide range.

[0029] In some examples, such as Figure 3As shown, the angle adjustment assembly includes a mounting plate 8, a rotating shaft 9, a rotating rod 10, and a drive assembly. Two mounting plates 8 are provided, both fixedly mounted on the side of the connecting frame 2. The rotating shaft 9 is rotatably mounted between the two mounting plates 8. Two rotating rods 10 are provided, both fixedly mounted on the rotating shaft 9, and a rotating ring 3 is fixedly mounted between the two rotating rods 10. The drive assembly is mounted on the connecting frame 2 and includes a second motor 11, drive wheels 12, and a transmission belt 13. The second motor 11 is mounted on the side of the connecting frame 2. Two drive wheels 12 are provided, one fixedly mounted on the rotating shaft 9 and the other fixedly mounted on the output end of the second motor 11. The transmission belt 13 is tensioned and sleeved on the two drive wheels 12.

[0030] Specifically, when adjusting the angle of the blade, motor 2 11 is started. The output end of motor 2 11 drives one of the drive wheels 12 to rotate. Under the tension of the transmission belt 13, the other drive wheel 12 is driven to rotate. The drive wheel 12 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the rotating rod 10 to adjust the angle. The rotating rod 10 then drives the rotating assembly and the blade to adjust the angle. When passing over some low field ridges, the blade height can be slightly raised or lowered by adjusting the blade angle to allow it to pass. Motor 2 11 is connected to the side of the connecting frame 2 through the transmission belt 13. The connecting frame 2 passes through the transmission belt 13. When the connecting frame 2 is lowered, when the blade is grinding the straw, the flying straw or stones can be blocked by the connecting frame 2, so that they do not come into contact with motor 1 7 and are not damaged.

[0031] In some examples, such as Figure 4 As shown, the rotating assembly includes a fixed plate 14, a rotating plate 15, and a motor 16. The fixed plate 14 is fixedly installed between two rotating rods 10. A circular groove is provided on the inner side wall of the rotating ring 3. The rotating plate 15 is slidably installed in the circular groove of the rotating ring 3. The motor 16 is installed on the fixed plate 14, and the output end of the motor 16 is fixedly connected to the side of the rotating plate 15.

[0032] Specifically, if the slope of the field ridge is inclined, motor 16 can be started. The output end of motor 16 drives the rotating plate 15 to rotate in the circular groove within the rotating ring 3, thereby driving the mounting rod 20 and the cutter to rotate left and right, adjusting the angle so that the cutter passes over the slope of the field ridge. A protective cover 19 is detachably installed on the side of the fixing plate 14, and both the electric cylinder 17 and motor 16 are located inside the protective cover 19. Figure 5 and Figure 4 As shown, when the blade is cutting straw, the protective cover 19 can protect the motor 3 16, thereby preventing impurities from splashing onto the motor 3 16.

[0033] Working principle: When raising or lowering the tool, motor 7 can be started first, which drives the connecting frame 2 to adjust the height on the drive screw 5 and slide rod 6, thereby driving the mounting plate 8 and rotating shaft 9 to adjust the height. The rotating shaft 9 drives the rotating rod 10, which in turn drives the rotating ring 3 to adjust the height, thus adjusting the height of the tool. Motor 11 can also be started, and the output end of motor 11 drives the drive wheel 12 to rotate. Under the tension of the transmission belt 13, the drive wheel 12 on the rotating shaft 9 rotates, thereby driving the rotating shaft 9 to rotate. The rotating shaft 9 drives the rotating rod 10 to rotate, thus driving the tool to rotate up and down for fine-tuning the height. Finally, motor 16 is started, and the output end of motor 16 drives the rotating plate 15 to rotate in the circular groove inside the rotating ring 3. The rotating plate 15 drives the mounting rod 20 and the tool on the mounting rod 20 to rotate left and right.

[0034] Example 2: like Figure 4 As shown, it also includes a limiting component. There are two limiting components, including an electric cylinder 17 and a limiting block 18. The electric cylinder 17 is installed on the side of the fixed plate 14, and the limiting block 18 is fixedly installed on the output end of the electric cylinder 17. Two limiting holes are opened on the side of the rotating plate 15, and the limiting holes are adapted to the limiting block 18. Specifically, when the rotating plate 15 does not need to rotate in the rotating ring 3, the electric cylinder 17 can be activated. The output end of the electric cylinder 17 pushes the limiting block 18 into the limiting hole of the rotating plate 15, thereby limiting the rotating plate 15. The protective cover 19 can protect the electric cylinder 17.

[0035] Working principle: By starting the electric cylinder 17, the output end of the electric cylinder 17 drives the limit block 18 to move forward, inserting the limit block 18 into the limit hole of the rotating plate 15, thereby limiting the rotating plate 15.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it.
