Problems solved by technology
[0003] The xylem skin of the reed stalks in the mature stage is thicker and harder in texture. According to the applicant’s knowledge, the reciprocating double-knife triangular tine cutters currently used in reed harvesters generally have the problems of high cutting resistance and high power consumption.
And practice has proved that in fact there is a big problem with the cutting quality, because the existing cutting blades cannot reliably cut off the reed stalks in time, and as the harvester advances, the reed stalks will be pushed down by the cutter, resulting in missed cuts, A series of chain reactions such as clogging of the cutting table and dumping of stalks lead to frequent failures of machine harvesting, which seriously affects the work efficiency and machine harvesting benefits of reed harvesting

Embodiment 1
[0027] The bionic cutting blade of the reed harvester of the present embodiment is as follows: figure 1 As shown, the blade base 1 is composed of an isosceles triangle and a rectangular handle end, and is approximately an isosceles triangle, with upper and lower surfaces 1-1, 1-2, and two hypotenuses. The rectangular end of the blade base 1 is provided with a positioning hole 4 .
[0028] The insert base body 1 transitions from two hypotenuses of the lower surface 1-2 to the upper surface 1-1 through the edge face 3 forming the edge angle β of the insert respectively. A group of cutting teeth 2 are distributed on the outer side of the blade surface 3 at intervals.
[0029] Depend on figure 2 , image 3 It can be seen that the cutting tooth 2 is composed of a cylindrical tooth back 2-1 and a cutting tooth profile S, and the cylinder axis forming the cylindrical tooth back 2-1 forms a tooth tip angle γ greater than the blade angle β with the lower surface 1-2, and the cuttin...

The invention relates to a bionic cutting blade of a reed harvester, which belongs to the technical field of agricultural machinery and equipment. The blade includes a blade base body with upper and lower surfaces and two beveled sides. The blade base body transitions from the two beveled sides of the lower surface to the upper surface through the edge face forming the edge angle of the blade respectively. The cutting tooth is composed of a cylindrical tooth back and a cutting tooth profile. The cylindrical axis forming the cylindrical tooth back and the lower surface form a tooth tip angle greater than the blade angle. Isometric curves for tooth fitting curves. The cutting resistance is significantly reduced by adopting the present invention, so the power consumption is greatly reduced, and the cutting quality is good, completely avoiding the reed stalks being pushed down by the cutting knife and the clogging of the cutting platform. There is reason to believe that the long-term evolution of long-term beetles has formed a unique upper jaw in chewing and biting. It is an ideal and optimal design to apply bionics to the cutting blades of reed harvesters.
Description
technical field [0001] The invention relates to a cutting knife, in particular to a bionic cutting blade of a reed harvester and a manufacturing method thereof, belonging to the technical field of agricultural machinery and equipment. Background technique [0002] Phragmites reed is a perennial gramineous plant, which can be harvested many times after one planting. It is a very important ecological, social and economic resource. Advantage. [0003] The xylem skin of reed stalks in the mature stage is thicker and harder in texture. According to the applicant's knowledge, the reciprocating double-knife triangular tine cutters currently used in reed harvesters generally have the problems of high cutting resistance and high power consumption. And practice has proved that in fact there is a big problem in the cutting quality, because the existing cutting blades cannot reliably cut off the reed stalks in time, and as the harvester advances, the reed stalks will be pushed down by ...
