Background
Sugarcane is used as a main sugar material source in China, the planting area is large, but the harvesting is still mainly performed manually. In recent years, sugarcane is moving towards mechanized harvesting, with segmented harvesting being the mainstay.
During harvesting, the sugarcane tips enter the conveying mechanism along with the sugarcane, and as the suspension speed of the sugarcane tips and the sugarcane section is basically consistent, the sugarcane tips are not easy to separate from the sugarcane leaf separating device, so that the impurity content after harvesting is greatly increased, and therefore, the sugarcane tips are required to be cut before harvesting. However, the existing tip cutter on the sugarcane harvester only has an effect on upright sugarcane, when the lodging of the sugarcane is serious, the tip cutter does not work, the sugarcane tips are fed along with the sugarcane sections, and the impurity content of the sugarcane is greatly influenced.
However, most of sugarcane in China is seriously affected by typhoon monsoon, the lodging condition is serious, and the tip cutter has no effect. Especially in the south of China, most sugarcane is planted in sloping fields and hilly areas, and is greatly influenced by typhoons and monuments, and the lodging condition is serious. Therefore, the front end of the harvester is often provided with a sugarcane supporting device, so that sugarcane in different lodging states is supported to a proper angle, and can be smoothly fed into a tip cutting device opening, and a tip cutting function is realized. However, in practical application, the lifted sugarcane often directly enters the rear conveying mechanism without entering the tip cutter opening due to the problem of angle, and the sugarcane tip cutting proportion is low.
Aiming at the current situation that the lodging rate of sugarcane in China is high, the sugarcane tip cutting device is needed to realize the function of cutting the vertical sugarcane tips of the sugarcane by the common tip cutter, and can achieve the effect on the lodged sugarcane as well, and has strong functions and strong practicability.

In the present embodiment, four blades 414 are uniformly distributed in the circumferential direction;
in the present embodiment, the distance by which the cutting blade 412 protrudes from the cutter head 411 (theoretical effective cutting distance of the cutting blade 412) is 90mm, and the maximum distance by which the tip of the cutting blade 412 protrudes from the rack 4212 is 60mm;

2. along with the advancing of the sugarcane 5 harvester, the sugarcane 5 is regularly fed into the sugarcane integrating port 421 in the direction perpendicular to the cutter head, and the sugarcane 5 entering the sugarcane integrating port 421 is mainly concentrated in two clamping spaces 4213 among three teeth, and enters and is fixed in the two clamping spaces 4213;
3. under the drive of the hydraulic motor 416, the rotating shaft 415 drives the cutter 411 and the cutting blade 412 bolted to the cutter 411 to rotate at a high speed, sugarcane tips fixed in the two clamping spaces 4213 are cut off under the high-speed rotation of the cutting blade 412, and then the tips are thrown into the field by the blades 414 on the cutter 411, so that the tips are cut firstly and then cut and harvested.
As shown in fig. 4, the working procedure of this embodiment when encountering severely lodged sugarcane is:
1. the hydraulic cylinder I21 and the hydraulic cylinder III 22 are stretched, the hydraulic cylinder II 24 is contracted, the lifting arm I2 rotates backwards, and the tip cutting device descends and rotates to the position, close to an angle of 40 degrees, of the lower support plate 422 and the horizontal plane under the combined action of the hydraulic cylinder and the lifting arm;
2. a sugarcane pressing roller 7 and a sugarcane lifter 6 are sequentially arranged in front of the sugarcane harvester, and sugarcane 5 lifted by the sugarcane lifter 6 can be fed into the sugarcane integrating port 421 at different angles;
3. along with the advance of the harvester of the sugarcane 5, the sugarcane lifter 6 lifts the sugarcane 5 to a certain angle, and the lodged sugarcane 5 is irregularly arranged right in front of the embodiment; after being gathered by the sugarcane separating rods 4212, the sugarcane 5 is fixed in four clamping spaces 4213;
4. under the drive of the hydraulic motor 416, the rotating shaft 415 drives the cutter 411 and the cutting blade 412 bolted to the cutter 411 to rotate at a high speed, sugarcane tips fixed in the four clamping spaces 4213 are cut off under the high-speed rotation of the cutting blade 412, and the cut sugarcane tips are thrown into the field by the blades 414 on the cutter 411, so that the tips are firstly supported and then removed.
In this workflow, the stress conditions of the irregularly arranged sugar cane 5 during cutting are different, and the sugar cane 5 farther from the center needs to be clamped more sufficiently in high-speed movement to ensure that the outer sugar cane tips are completely cut.
In the working flow, as the lodged sugarcane 5 can be fed in a plurality of different angles, the tooth width of the rack 4211 is larger than the diameter of the sugarcane 5, and the inlets of the clamping spaces 4213 on two sides have larger widths, the lodged sugarcane 5 which is in a plurality of angles with the ground after being propped up can be just clamped; therefore, the adaptability is stronger, and more convenience can be provided for mechanized tip cutting.
