Description

Technical Field

[0001] This utility model relates to the field of sugarcane harvester technology, specifically to a reversing conveying device for a sugarcane harvester. Background Technology

[0002] Sugarcane is a crop grown in temperate and tropical zones and is the main raw material for extracting sugar. The rhizome of sugarcane is the primary sugar-containing part. Mature sugarcane rhizomes typically reach a height of 3 to 5 meters. To effectively improve harvesting efficiency and reduce harvesting time, automated harvesting equipment is usually used when sugarcane matures.

[0003] CNCN223286230U discloses a bidirectional sugarcane cutter and spreader. Sugarcane is conveyed vertically via a left and right rubber roller chain. Depending on the terrain, the cut sugarcane is laid to the left or right. Operation is achieved by adjusting the position of the rear clamping and reversing mechanism on the clamping and conveying lifting frame. When the rear clamping and reversing mechanism exceeds the left U-shaped frame, sugarcane is laid to the left; when it exceeds the right U-shaped frame, sugarcane is laid to the right. The adjustment mechanism is driven by a rack and pinion mechanism. This structure requires adjusting the rear clamping and reversing mechanism to the designated position for each reversal, resulting in a relatively long waiting time and requiring the entire rear clamping and reversing mechanism to be moved. The overall structure has a large mass and consumes a lot of energy during movement. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a reversing conveyor device for a sugarcane harvester.

[0005] Technical solution

[0006] A reversing conveying device for a sugarcane harvester includes a left-side clamping reversing mechanism, a middle-side clamping reversing mechanism, and a right-side clamping reversing mechanism. The middle-side clamping reversing mechanism is located behind the outlet of the front clamping conveying rubber roller chain assembly and includes two sets of upper and lower opposing and synchronously moving middle clamping conveying toothed chains. The left-side clamping reversing mechanism includes two sets of upper and lower opposing and synchronously moving left clamping conveying toothed chains. The right-side clamping reversing mechanism includes two sets of upper and lower opposing and synchronously moving right clamping conveying toothed chains. The toothed chain can only rotate forward, the right clamping conveyor toothed chain can only rotate in reverse, and the middle clamping conveyor toothed chain can rotate in both forward and reverse. The tooth spacing of the middle clamping conveyor toothed chain, the left clamping conveyor toothed chain, and the right clamping conveyor toothed chain is the same. The middle clamping conveyor toothed chain, the left clamping conveyor toothed chain, and the right clamping conveyor toothed chain are all driven by two sprockets. The two sprockets of the middle clamping conveyor toothed chain are vertically opposite to the right sprocket of the left clamping conveyor toothed chain and the left sprocket of the right clamping conveyor toothed chain, respectively, and the teeth in front of the two vertically opposite sprockets are also vertically opposite.

[0007] Furthermore, the left side of the left clamping reversing mechanism is provided with a left U-shaped frame, and the left side of the left clamping reversing mechanism extends beyond the left U-shaped frame; the right side of the right clamping reversing mechanism is provided with a right U-shaped frame, and the right side of the right clamping reversing mechanism extends beyond the right U-shaped frame.

[0008] Furthermore, one of the sprockets of the intermediate clamping and conveying toothed chain is connected to a forward and reverse motor, which is mounted on the intermediate fixed frame.

[0009] Furthermore, one of the sprockets of the left clamping and conveying toothed chain is connected to a forward rotation motor, which is mounted on the left fixed frame.

[0010] Furthermore, one of the sprockets of the right clamping and conveying toothed chain is connected to a reverse motor, which is mounted on the right fixed frame.

[0011] Furthermore, an auxiliary dial is also installed on the intermediate fixed frame. The auxiliary dial includes a rotating shaft that is rotatably connected to the fixed frame. The rotating shaft is connected to a forward and reverse motor. A fixed dial is fixed on the rotating shaft. Multiple rubber rods are evenly arranged around the fixed dial.

[0012] Beneficial effects:

[0013] This utility model provides a reversing conveying device for a sugarcane harvester. By adjusting the rotation direction of the intermediate clamping reversing mechanism, the laying direction of the sugarcane can be changed, which facilitates flexible adjustment of the sugarcane laying position during harvesting. When reversing, only the rotation direction of the forward and reverse motors needs to be adjusted by electrical control, which can respond quickly and does not require a long waiting time, thus improving the sugarcane harvesting efficiency.

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] As attached Figure 1 To be continued Figure 2 . Specific implementation examples:

[0019] A reversing conveying device for a sugarcane harvester includes a left clamping reversing mechanism 1, a middle clamping reversing mechanism 2, and a right clamping reversing mechanism 3. The middle clamping reversing mechanism 2 is located behind the outlet of the front clamping conveying rubber roller chain assembly (not shown in the figure). The middle clamping reversing mechanism 2 includes two sets of upper and lower opposing and synchronously moving middle clamping conveying toothed chains 4. The left clamping reversing mechanism 1 includes two sets of upper and lower opposing and synchronously moving left clamping conveying toothed chains 5. The right clamping reversing mechanism 3 includes two sets of upper and lower opposing and synchronously moving right clamping conveying toothed chains 6. The left clamping conveying toothed chains 5... The right clamping conveyor chain 6 can only rotate in the forward direction, while the middle clamping conveyor chain 4 can rotate in both directions. The tooth spacing of the middle clamping conveyor chain 4, the left clamping conveyor chain 5, and the right clamping conveyor chain 6 is the same. The middle clamping conveyor chain 4, the left clamping conveyor chain 5, and the right clamping conveyor chain 6 are all driven by two sprockets 7. The two sprockets 7 of the middle clamping conveyor chain 4 are vertically opposite to the right sprocket 7 of the left clamping conveyor chain 5 and the left sprocket 7 of the right clamping conveyor chain 6, and the teeth in front of the two vertically opposite sprockets 7 are also vertically opposite.

[0020] A left U-shaped frame 8 is provided on the left side of the left clamping reversing mechanism 1, and the left side of the left clamping reversing mechanism 1 extends beyond the left U-shaped frame 8; a right U-shaped frame 9 is provided on the right side of the right clamping reversing mechanism 3, and the right side of the right clamping reversing mechanism 3 extends beyond the right U-shaped frame 9.

[0021] In actual operation, the front clamping conveyor roller chain assembly keeps the cut sugarcane vertically conveyed to the middle position of the intermediate clamping reversing mechanism 2. The intermediate clamping reversing mechanism 2 adjusts the rotation direction of the intermediate clamping conveyor toothed chain 4 according to the required sugarcane laying direction. Taking left-side laying as an example, it is adjusted to rotate forward. The sugarcane entering the intermediate clamping reversing mechanism 2 is clamped and conveyed by the teeth on the intermediate clamping conveyor toothed chain 4. When it is conveyed to the front of the left sprocket of the intermediate clamping conveyor toothed chain 4, the teeth on the intermediate clamping conveyor toothed chain 4 clamping the sugarcane begin to move in an arc around the sprocket. The sugarcane moves in a straight line to the left as one of the teeth in front of the right sprocket of the left clamping reversing mechanism 1 begins to move the sugarcane to the left. Since the linear velocity of the middle clamping conveying tooth chain 4 and the left clamping reversing mechanism 1 is the same, the horizontal offset of the tooth moving along the arc path will be significantly smaller than the horizontal offset of the tooth moving along the straight path. The left clamping reversing mechanism 1 will then take over the tooth of the middle clamping conveying tooth chain 4 and continue to clamp the sugarcane to the left until it is detached from the left clamping reversing mechanism 1 and laid on the left U-shaped frame 8. When it is laid on the right U-shaped frame 9, the middle clamping conveying tooth chain 4 is reversed.

[0022] From the above operation process, we can see that this utility model only needs to adjust the rotation direction of the intermediate clamping reversing mechanism 2 to adjust the sugarcane laying direction. Compared with the prior art, it does not require waiting time, can respond quickly, and is more flexible in operation. When harvesting sugarcane, a continuous S-shaped harvesting path can be selected, instead of being limited to a zigzag or a single parallel direction, making it suitable for harvesting work in various terrains.

[0023] One of the sprockets 7 of the intermediate clamping and conveying toothed chain 4 is connected to the forward and reverse motor 12, which is mounted on the intermediate fixed frame. The forward and reverse motor 12 is electrically controlled to control its rotation direction and can respond quickly.

[0024] One of the sprockets 7 of the left clamping and conveying toothed chain 5 is connected to a forward rotating motor 10, which is mounted on the left fixed frame. One of the sprockets 7 of the right clamping and conveying toothed chain 6 is connected to a reverse rotating motor 11, which is mounted on the right fixed frame.

[0025] An auxiliary dial 13 is also installed on the intermediate fixed frame. The auxiliary dial 13 includes a rotating shaft that is rotatably connected to the fixed frame. The rotating shaft is connected to a forward and reverse motor 12. A fixed dial is fixed on the rotating shaft, and multiple rubber rods are evenly arranged around the circumference of the fixed dial. The auxiliary dial 13 mainly assists the sugarcane in entering the clamping area of ​​the intermediate clamping and conveying toothed chain 4, and its rotation direction is consistent with that of the intermediate clamping and conveying toothed chain 4.

[0026] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
