One of the sprockets is connected to an external power device, which can be a hydraulic motor or an electric motor, 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, so that the two rotating rollers rotate inward relative to each other, so as to feed, transport, peel and separate the sugarcane.

[0036] refer to Figures 1 to 3, the third moving mechanism can be a telescopic cylinder structure, or a structure such as a screw nut. Preferably, the third moving mechanism includes a second guide rail 15, a second slider, a third screw rod 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-to-back direction.

[0037] refer to Figures 1 to 3 Through the action of the first moving mechanism, the second moving mechanism and the third moving mechanism, 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: the movable roller 21 moves up and down, the first movable tensioning wheel 13 and the second movable tensioning wheel 16 move in the same direction to make corresponding adjustments, keeping the length of the chain 11 on both sides from the movable roller 21 to the fixed roller 22 changing synchronously, so as to keep the chain 11 always in the tensioning device, not interfering with the movement of the movable roller 21, and not changing the roller phase relationship. 13 represents the displacement of the first movable tensioning wheel 13, S 16 represents the displacement of the second active tensioning wheel 16, while the displacement of the active roller 21 is S 7 , then S 13 , S 16 and S 7 The following formula (1) is satisfied:

[0039] S 13 =S 16 =0.5S 7 (1)

[0040] At this time, the spacing between the rotating rollers can be adjusted autonomously, so that when the density of harvested sugarcane is high, there are more sugarcanes in the feeding channel, or the diameter of the sugarcane is large, the spacing can be appropriately increased to reduce the force applied to the sugarcane and avoid channel blockage; and when the density of sugarcane in the feeding channel is low, there are fewer sugarcanes in the feeding channel, or the diameter of the sugarcane is small, the spacing can be reduced to apply a stronger force to the sugarcane and bring about a better leaf stripping effect.

[0041] (2) Roller phase adjustment, spacing unchanged: The movable roller 21 is not moved, and the positions of the first movable tensioning wheel 13 and the second movable tensioning wheel 16 are adjusted in the opposite direction. While keeping the total length of the chain 11 unchanged, the length of the chain 11 on both sides between the first movable tensioning wheel 13 and the second movable tensioning wheel 16 is reduced on one side and increased on the other side, thereby changing the roller phase. 13 represents the displacement of the first movable tensioning wheel 13, S 16 represents the displacement of the second active tensioning wheel 16, then S 13 , S 16 The following formula (2) is satisfied:

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

[0043] The negative sign in formula (2) represents the opposite direction of movement. Assuming that the fixed roller 22 does not rotate, the chain 11 here does not slide, but the chain 11 at the movable roller 21 will slide due to the reverse movement of the movable tension wheel, so that the movable roller 21 will rotate at a certain angle, causing the relative phase change between the movable roller 21 and the fixed roller 22. On the contrary, assuming that 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, which will also cause a relative phase change. When used on the leaf stripping roller, due to the high rotation speed of the leaf stripping roller and the slow running and conveying speed of the sugarcane, the leaf stripping brush hits the sugarcane many times per second. Assuming that when the phase difference between the upper and lower rollers is 0, it is assumed that the upper and lower leaf stripping brushes rotate and pass through the center line of the two roller shafts at the same time. At this time, the impact force of the leaf stripping brush on the sugarcane is concentrated at the same time and the same point. When the impact force is large and the allowable force of the sugarcane is small, it can form a good support for the sugarcane, thereby avoiding broken joints as much as possible without affecting the impact force; when the phase difference between the upper and lower rollers increases, the time when the leaf stripping brush passes through the center line of the roller shafts is not at the same time, and there is an angle difference in the rotation angle, so 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 of the sugarcane stalk. In this way, when the impact force is small and the allowable force of the sugarcane is larger, a more uniform impact and leaf stripping effect can be obtained within the range of continuous joints.

[0044] (3) The spacing and roller phase are adjusted simultaneously: the movable roller 21 moves up and down, and the movement of the first movable tensioning wheel 13 and the second movable tensioning wheel 16 is controlled by the common mode component (synchronous adjustment) and the differential mode component (reverse adjustment). Phase change Proportional to the differential modulus, phase change is the rotation phase change of the movable roller 21 when the fixed roller 22 does not rotate; Satisfies formula (3):

[0045]

[0046] In formula (3), K 差 is the differential mode proportionality coefficient, S 13 is the displacement of the first movable tensioning wheel 13, S 16 is the displacement of the second movable tensioning wheel 16.

[0047] The spacing variation ΔH is proportional to the common modulus. The spacing variation ΔH is the variation of the center spacing between the movable roller 21 and the fixed roller 22. ΔH satisfies formula (4):

[0048]

[0049] In formula (4), K 共 is the common mode proportionality coefficient, S 13 is the displacement of the first movable tensioning wheel 13, S 16 is the displacement of the second movable tensioning wheel 16.

[0050] If the phase adjustment changes greatly, the differential mode component of the reverse adjustment will be more obvious, and the displacements of the two active tension wheels will be greatly different; if the spacing adjustment changes greatly, the common mode component of the synchronous adjustment will be more obvious, and the displacements of the two active tension wheels will be more consistent. Through the above methods, the force (spacing) and the distribution point (phase) of the striking force of the leaf stripping brush on the sugarcane can be adjusted independently, so that it can adapt to various working conditions.

[0051] The two movable tension wheels and the first sprocket 6 of the present invention are controlled by the "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 breakage phenomenon.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
