Description

Technical Field

[0002] The rotating rollers in the sugarcane cleaning channel perform operations such as feeding, conveying, peeling, and separating harvested sugarcane, separating leaves and soil. The spacing and rotation speed of the rotating rollers affect clogging prevention, while the rotation speed, spacing, and phase of the peeling rollers all affect the peeling effect and the occurrence of leaf breakage. Existing sugarcane cleaning channels typically only adjust the spacing and rotation speed of the rotating rollers, lacking a mechanism for adjusting the phase. Therefore, it is necessary to add adjustment devices for rotation speed, spacing, and phase to the existing cleaning channel to improve the peeling effect and reduce leaf breakage.

Detailed Implementation

[0028] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0029] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0030] Figures 1 to 3 A schematic diagram of a parameter adjustment device for a sugarcane impurity removal channel 4 according to a preferred embodiment of the present invention is shown. (Refer to...) Figures 1 to 3An adjusting device is installed on a pair of rotating rollers in the sugarcane impurity removal channel 4 to adjust the distance and phase relationship between the two rotating rollers. Rotating rollers can be classified according to their purpose as feeding rollers, conveying rollers, leaf separating rollers, and leaf stripping rollers, etc. The adjusting device includes a first moving mechanism, a drive device, a second moving mechanism, and a third moving mechanism.

[0031] refer to Figures 1 to 3 The rotating rollers include a movable roller 21 and a fixed roller 22. The movable roller 21 is located above the fixed roller 22 and can move up and down. A first moving mechanism is installed on the sugarcane cleaning channel 4 to drive the movable roller 21 to move up and down, thereby adjusting the distance between the two rotating rollers to suit different sugarcane diameters, densities, and the amount of sugarcane fed into the channel, improving the leaf-removing effect and reducing breakage. The driving device includes a sprocket, a tensioning wheel, a movable tensioning wheel, and a chain 11. Each rotating roller has a sprocket at its end. The sprocket on the movable roller 21 is the first sprocket 6, and the sprocket on the fixed roller 22 is the second sprocket 8. The tensioning wheel and the movable tensioning wheel are rotatably mounted on the sugarcane cleaning channel 4. The tensioning wheel includes a fourth tensioning wheel 17, which is installed on the sugarcane cleaning channel 4 and located below and behind the second sprocket 8. The movable tensioning rollers include a first movable tensioning roller 13 and a second movable tensioning roller 16. The first movable tensioning roller 13 is mounted between two sprockets in a manner that allows it to move back and forth, and the second movable tensioning roller 16 is mounted below the front of the second sprocket 8 in a manner that allows it to move back and forth. A chain 11 is wound around the front side of the first movable tensioning roller 13, the top of the first sprocket 6, the rear side of the fourth tensioning roller 17, the front side of the second movable tensioning roller 16, and the rear side of the second sprocket 8. One of the sprockets is connected to an external power device, which can be a hydraulic motor or an electric motor, etc., and the speed can be adjusted by adjusting the input power. Through the transmission of the chain 11, the other sprocket is driven to rotate in the opposite direction, thereby causing the two rotating rollers to rotate inward relative to each other to perform operations such as feeding, conveying, peeling, and separating sugarcane. A second moving mechanism is installed on the sugarcane cleaning channel 4 and is used to drive the first movable tensioning roller 13 to move back and forth, thereby adjusting the position of the first movable tensioning roller 13. The third moving mechanism is installed on the sugarcane cleaning channel 4 and is used to drive the second movable tension wheel 16 to move back and forth, thereby adjusting the position of the second movable tension wheel 16. When the movable roller 21 moves up and down, the chain 11 can be kept in a taut state by adjusting the positions of the first movable tension wheel 13 and the second movable tension wheel 16 to ensure the transmission effect. It can also be adjusted as needed to change the phase relationship between the rotating rollers, further improving the leaf stripping effect and reducing the breakage phenomenon.

[0032] refer to Figures 1 to 3Preferably, the tensioning pulley further includes two first tensioning pulleys 10, two second tensioning pulleys 14, and a third tensioning pulley 23. The two first tensioning pulleys 10 are located below the first sprocket 6 and are spaced apart in the front-to-back direction. The two second tensioning pulleys 14 are located below the two first tensioning pulleys 10 and are spaced apart in the front-to-back direction. The first tensioning pulleys 10 and 14 are arranged in a one-to-one correspondence, and each second tensioning pulley 14 is located below and behind its corresponding first tensioning pulley 10. The third tensioning pulley 23 is located between the front second tensioning pulleys 14 and the second sprocket 8. A first movable tensioning pulley 13 is mounted in front of the front second tensioning pulleys 14 and 23 in a manner that allows it to move back and forth. Chain 11 is wound around the front sides of the two first tensioning pulleys 10, the top of the first sprocket 6, the rear sides of the two second tensioning pulleys 14, the front side of the first movable tensioning pulley 13, the rear side of the third tensioning pulley 23, the rear side of the second sprocket 8, the front side of the second movable tensioning pulley 16, and the rear side of the fourth tensioning pulley 17. To achieve the simplest parameter adjustment, the contact range between chain 11 and sprockets on the first movable tensioning pulley 13, the second movable tensioning pulley 16, and the first sprocket 6 is 180°. That is, the chain 11 entering and exiting the first sprocket 6 and the chain 11 on the movable tensioning pulley are parallel, and the direction of chain 11 is parallel to the direction of movement of the axis of the first sprocket 6, and the direction of chain 11 is parallel to the direction of movement of the movable tensioning pulley. Maintaining this state throughout the adjustment process simplifies the control algorithm, because the magnitude of the change in chain length 11 at any time is directly equal to twice the magnitude of the shaft displacement of the first sprocket 6, or the magnitude of the change in chain length 11 is directly equal to twice the magnitude of the shaft displacement of the movable tension wheel.

[0033] refer to Figures 1 to 3 Preferably, the left and right side walls of the sugarcane impurity removal channel 4 are provided with through holes 20 distributed along the vertical direction at positions corresponding to the movable roller 21. The left and right ends of the movable roller 21 pass through the corresponding through holes 20 and extend outward, and the movable roller 21 can move up and down along the through holes 20.

[0034] refer to Figures 1 to 3The first moving mechanism can be a telescopic cylinder structure or a screw and nut structure.

The first motor 1 is mounted on the sugarcane cleaning channel 4, and the first motor 1 corresponds one-to-one with the first screw 3. The rotating shaft of each first motor 1 is connected to the corresponding first screw, driving the first screw 3 to rotate synchronously. A moving platform 7 is provided between two adjacent first screws 3, and each moving platform 7 has sleeves 5 threadedly connected to the corresponding first screw 3 on both its front and rear sides. The two ends of the movable roller 21 are rotatably connected to the corresponding moving platform 7. By driving the four first screws 3 to rotate synchronously in the forward or reverse direction, the sleeves 5 can be driven to move up and down, thereby driving the moving platform 7 to move up and down, adjusting the distance between the movable roller 21 and the fixed roller 22.

[0035] refer to Figures 1 to 3 The second moving mechanism can be a telescopic cylinder structure or a screw and nut structure. Preferably, the second moving mechanism includes a first guide rail 12, a first slider, a second screw 9, and a second motor 2. The first guide rail 12 is installed on the sugarcane impurity removal channel 4, and the length of the first guide rail 12 is distributed along the front-back direction. The first slider is installed on the first guide rail 12 in a manner that allows it to slide left and right, and a first movable tension wheel 13 is installed on the first slider. The second screw 9 is installed on the sugarcane impurity removal channel 4 in a manner that allows it to rotate, and the length of the second screw 9 is distributed along the front-back direction.

The second motor 2 is installed on the sugarcane impurity removal channel 4, and the shaft of the second motor 2 is connected to the second screw 9 to drive the second screw 9 to rotate. By rotating the second screw 9 forward or backward, the first slider can be driven to move back and forth, thereby driving the first movable tension wheel 13 to move back and forth.

[0036] refer to Figures 1 to 3The third moving mechanism can be a telescopic cylinder structure or a screw and nut structure. Preferably, the third moving mechanism includes a second guide rail 15, a second slider, a third screw 19, and a third motor 18. The second guide rail 15 is installed on the sugarcane impurity removal channel 4, and the length of the second guide rail 15 is distributed along the front-back direction. The second slider is installed on the second guide rail 15 in a manner that allows it to slide left and right, and the second movable tension wheel 16 is installed on the second slider. The third screw 19 is installed on the sugarcane impurity removal channel 4 in a manner that allows it to rotate, and the length of the third screw 19 is distributed along the front-back direction. The second slider and the third screw 19 are threadedly connected. The third motor 18 is installed on the sugarcane impurity removal channel 4, and the shaft of the third motor 18 is connected to the third screw 19 to drive the third screw 19 to rotate. By rotating the third screw 19 forward or backward, the second slider can be driven to move back and forth, thereby driving the second movable tension wheel 16 to move back and forth.

[0037] refer to Figures 1 to 3 Through the action of the first, second, and third moving mechanisms, the spacing and phase of the rotating rollers can be adjusted in the following three ways:

[0038] (1) Spacing adjustment, roller phase relationship remains unchanged: When the movable roller 21 moves up and down, the first movable tension wheel 13 and the second movable tension wheel 16 both move in the same direction to make corresponding adjustments, keeping the lengths of the chains 11 on both sides from the movable roller 21 to the fixed roller 22 changing synchronously, thereby keeping the chains 11 always in the tensioning device, not interfering with the movement of the movable roller 21, and not changing the roller phase relationship. (S) 13 S represents the displacement of the first movable tensioning wheel 13. 16 S represents the displacement of the second movable tensioning wheel 16, and the displacement of the movable roller 21 is S7. Therefore, S... 13 、S 16 S7 and S7 satisfy the following formula (1):

[0039] S 13 =S 16 =0.5S7 (1)

[0040] At this point, the spacing between the rotating rollers can be adjusted automatically. When the sugarcane density is high, there is a lot of sugarcane in the feeding channel, or the sugarcane diameter is large, the spacing can be increased appropriately to reduce the force applied to the sugarcane and avoid channel blockage. When the sugarcane density in the feeding channel is low, there is little sugarcane in the feeding channel, or the sugarcane diameter is small, the spacing can be reduced to apply a stronger force to the sugarcane, resulting in a better leaf-peeling effect.

[0041] (2) Roller phase adjustment, spacing unchanged: The movable roller 21 remains stationary, while the positions of the first movable tension wheel 13 and the second movable tension wheel 16 are adjusted in opposite directions. While maintaining the total length of the chain 11 unchanged, the length of the chain 11 on both sides between the first movable tension wheel 13 and the second movable tension wheel 16 decreases on one side and increases on the other, thus changing the roller phase. (S) 13 S represents the displacement of the first movable tensioning wheel 13. 16 S represents the displacement of the second movable tensioning wheel 16. 13 、S 16 The following formula (2) must be satisfied:

[0042] S 13 =-S 16 (2)

[0043] In formula (2), the negative sign indicates the opposite direction of motion. Assuming the fixed roller 22 does not rotate, the chain 11 does not slide, but the chain 11 at the movable roller 21 will tend to slide due to the reverse movement of the movable tension wheel. As a result, the movable roller 21 will rotate at a certain angle, causing a relative phase change between the movable roller 21 and the fixed roller 22. Conversely, assuming the movable roller 21 does not rotate, the chain at the fixed roller 22 will slide due to the pull of the movable tension wheel, and the fixed roller 22 will rotate at a certain angle, also causing a relative phase change. When applied to a leaf-stripping roller, because the leaf-stripping roller has a high rotation speed and the sugarcane's conveying speed is slow, the leaf-stripping brush strikes the sugarcane many times per second. Assuming the phase difference between the upper and lower rollers is 0, the leaf-peeling brushes rotate and pass the line connecting the centers of the two roller shafts simultaneously. At this time, the impact force of the leaf-peeling brushes on the sugarcane is concentrated at the same moment and the same point. When the impact force is large and the sugarcane can withstand less stress, it can provide good support for the sugarcane, thus avoiding breakage as much as possible without affecting the impact force. However, when the phase difference between the upper and lower rollers increases, the leaf-peeling brushes do not pass the line connecting the centers of the roller shafts at the same time, and there is an angle difference in the rotation angle. The impact force on the sugarcane is distributed at different times. Due to the backward conveying of the sugarcane, the impact force does not act on the same point on the sugarcane stalk. In this way, when the impact force is small and the sugarcane can withstand more stress, a more uniform impact and leaf-peeling effect can be obtained within the range of no breakage.

[0044] (3) Simultaneous adjustment of pitch and roller phase: The movable roller 21 moves up and down, and the movement of the first movable tension wheel 13 and the second movable tension wheel 16 is jointly controlled by the common mode component (synchronous adjustment) and the differential mode component (reverse adjustment). Phase change amount Proportional to the differential modulus, phase change This refers to the rotational phase change of the movable roller 21 under the premise that the fixed roller 22 does not rotate; wherein, the amount of phase change... Satisfies formula (3):

[0045]

[0046] In formula (3), K 差 S is the differential modulus scaling factor. 13 S represents the displacement of the first movable tensioning wheel 13. 16 The displacement of the second active tensioning wheel 16.

[0047] The pitch change ΔH is proportional to the common modulus. The pitch change ΔH is the change in the center distance between the movable roller 21 and the fixed roller 22, and ΔH satisfies formula (4):

[0048]

[0049] In formula (4), K 共 S is the common-mode scaling factor. 13 S represents the displacement of the first movable tensioning wheel 13. 16 The displacement of the second active tensioning wheel 16.

[0050] If the phase adjustment changes significantly, the differential mode component of the reverse adjustment will be more pronounced, resulting in a greater difference in the displacement of the two movable tensioning wheels. Conversely, if the spacing adjustment changes significantly, the common mode component of the synchronous adjustment will be more pronounced, leading to more consistent displacement of the two movable tensioning wheels. By employing these methods, the impact force (spacing) and impact force distribution point (phase) of the peeling brush on the sugarcane can be independently adjusted, thus adapting to various working conditions.

[0051] The two movable tensioning wheels and the first sprocket 6 of this invention are controlled by a "common modulus + differential modulus" method, so that the phase and spacing between the rotating rollers can be adjusted separately. The adjustment method is simple and convenient, which can improve the leaf stripping and impurity removal effect and reduce the phenomenon of section breakage.
