The yield is 5 to 10 tons per mu and it is widely used in biomass fuel, papermaking and other fields. In recent years, the scale of planting has become larger and larger. With the increase in the scale of planting, improving the harvesting efficiency is an urgent problem that needs to be solved.

[0003] Although the existing cutting table can harvest reed bamboo, such as patent number: 201611029717.4, patent name "A new type of reed bamboo harvester", a sawtooth rotary chain structure is set at the bottom of the front end of the cutting table, and the chain drives the rotating blade to achieve supported and unsupported cutting. However, due to the high stems of reed bamboo, the direction of the reed bamboo's falling cannot be controlled, resulting in a messy direction of the reed bamboo's falling during the harvesting process, making the harvesting unclean and even causing the harvester to get stuck, affecting the efficiency and effect of the harvest. Summary of the invention

[0058] Specifically, in the present embodiment, the middle support adjustment rod 5 comprises an outer sleeve 51 and an inner sleeve 52, one end of the outer sleeve 51 is hinged to the top of the cutting platform shell 1, one end of the inner sleeve 52 is slidably arranged in the other end of the outer sleeve 51, the inner sleeve 52 is fixedly connected by a fastening bolt 53 passing through the outer sleeve 51 and the inner sleeve 52, the other end of the inner sleeve 52 is rotatably connected to the rear push-down rod 4, specifically, a bearing 10 can be fixedly installed on the other end of the inner sleeve 52, the bearing 10 is sleeved in the middle of the rear push-down rod 4, one end of the inner sleeve 52 is slidably arranged in one end of the outer sleeve 51, when the support beam 2 is adjusted to a suitable inclination angle, the inner sleeve 52 and the outer sleeve 51 are fixed by the fastening bolt 53, thereby realizing effective support for the support beam 2.

[0059] In addition, in other embodiments of the present invention, the middle support adjustment rod 5 can also be a hydraulic support rod, one end of the hydraulic support rod is hinged to the top of the cutting table shell 1, and the other end of the hydraulic support rod is rotatably connected to the rear push-down rod 4. The middle support adjustment rod 5 adopts a hydraulic support rod. When adjusting the inclination angle of the support beam 2, the support beam 2 can be pulled or pushed by hydraulic pressure, which is more convenient to operate.

[0060] The support beam 2 is provided with a plurality of mounting holes arranged in sequence and at intervals along the length direction of the support beam 2. Both ends of the front push-down rod 3 and both ends of the rear push-down rod 4 are connected with mounting seats 11. The mounting seats 11 are connected to the mounting holes on the support beam 2 through positioning bolts 12, so as to realize the adjustment of the mounting positions of the front push-down rod 3 and the rear push-down rod 4, and further facilitate the knocking down setting of Phragmites australis with different growth tendencies.

[0061] Embodiment 5

[0062] This embodiment discloses a reed harvesting header, comprising the reed harvesting and knocking down device described above.

[0063] Working principle: When the reed cutting platform is driven by the main machine for harvesting, the front push-down rod 3 in the pressing device presses down the reed from the top, and at the same time, the rotatable structure of the front push-down rod 3 can effectively reduce the friction between the front push-down rod 3 and the epidermis and leaves of the reed, thereby achieving the purpose of reducing resistance and saving the power of the main machine. After the front push-down rod 3 bends the reed, in order to prevent the reed from rebounding, the rear push-down rod 4 further presses the bent reed, and when the cutter reaches the root of the reed, it is cut and harvested. The middle support adjustment rod 5 provides downward pressure to the rear push-down rod 4 to prevent the rear push-down rod 4 from deformation, thereby extending the service life of the push-down rod.

[0064] By adjusting the angles of the two support beams 2 and the upper and lower positions of the front push-down rod 3 and the rear push-down rod 4, the push-down position can be adjusted to adapt to the harvesting operation of crops with different growth potentials.

[0065] Beneficial effects of the present invention:

[0066] 1. The invention provides an adjustable knockdown device consisting of a front knockdown rod 3, a rear knockdown rod 4, a middle support adjustment rod 5, and adjustable frames on both sides;

[0067] 2. The front push-down rod 3 in the knock-down device can push the taller Phragmites australis from the top to tilt, and the rotating structure of the front push-down rod 3 can effectively reduce the friction rate between the front push-down rod 3 and the plant;

[0068] 3. The rear push-down rod 4 in the pressing device can effectively press the crops bent by the front push-down rod 3 for a second time to prevent them from popping out. The rear push-down rod 4 is a rotatable structure, which can effectively reduce the friction between the rear push-down rod 4 and the crops;

[0069] 4. The entire knocking device can adjust the knocking angle by adjusting the installation positions of the front push-down rod 3 and the rear push-down rod 4 on the upper part of the two support beams 2 according to the growth of the reed;

[0070] 5. The middle support adjustment rod 5 can effectively increase the strength of the knockdown device, reduce the deformation of the rear knockdown rod 4, and increase the service life of the knockdown device;

[0071] 6. The angle of the middle support adjustment rod 5 can be adjusted along with the angle of the pressing device;

[0072] 7. The position of the knockdown varies with the growth of the Phragmites australis. The position of the knockdown can be adjusted by adjusting the angle of the support beam 2 and the upper and lower positions of the front and rear push-down rods 3 and 4.
