Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The invention provides a cutter head profiling mechanism of a sugarcane harvester, which is shown in a figure 1 and comprises: a box body 1; a profiling device 2; a telescoping device 3; a cutting device 4; the two sides of the box body 1 are provided with telescopic devices 3; the lower end of the box body 1 is provided with the profiling device 2 and the cutting device 4; the profiling device 2 and the cutting device 4 are both connected with the telescopic device 3.

In this embodiment, the profiling devices and the cutting devices are both provided in two numbers, the profiling devices are disposed on two sides of the lower end of the box body, and the cutting devices are disposed between the profiling devices.

As shown in fig. 2, the copying device 2 includes: an inner rod 5, an outer rod 6, a central shaft 7, a small copying wheel 8, a disc 9 and a copying wheel shaft 10.

The upper end of the inner rod 5 is provided with a mounting hole, and the profiling device 2 is connected with a shaft 13 on the telescopic device through the mounting hole of the inner rod 5; the small copying wheel 8 and the copying wheel shaft 10 are connected on the disc 9 through keys, the central shaft 7 is connected with the outer rod 6 through a bearing, and the upper end of the copying device 2 is connected on a shaft 13. The two profiling devices are symmetrically distributed along the axis, and the distance between the two profiling devices can be adjusted in the axis direction to adapt to different ridge widths. The matching distance between the inner rod 5 and the outer rod 6 is adjustable, so that the ground clearance of the small copying wheel 8 can be controlled, and the ground clearance of the cutting device is indirectly guaranteed. The big copying wheel is composed of six small copying wheels 8, the six small copying wheels 8 are distributed on the circumference, the interval between every two small copying wheels 8 is 60 degrees, a gap is reserved between the small copying wheels 8, the big copying wheels rotate around the copying wheel shaft 10 of the big copying wheel and can rotate around the central shaft 7. When the contour wheel meets the bulge, the bulge contour wheel can be clamped, the central shaft 7 can be driven to rotate, and new contour wheels can contact the ground to continue to complete the profiling, so that the contour wheel can easily climb over the barrier to complete the profiling, and the condition that one contour wheel is always in contact with the ground and is damaged due to overlarge stress is avoided.

As shown in fig. 3, the telescopic device 3 includes: slide cartridge 11, connecting socket 12, shaft 13, ball 14 and spring 15.
