[0050] The crop gathering frame 10 is an arc-shaped tube, and is located above the middle rotary disc cutting and discharging device 13, the inner rotary disc cutting and discharging device 3 and the outer rotary disc cutting and discharging device 5. The crop gathering frame 10 includes a first fixed tube 101, a steel wire hose 102 and a second fixed tube 103. The first fixed tube 101 is arranged on the upper suspension frame 1. The steel wire hose 102 is located on both sides of the first fixed tube 101. One end of the two steel wire hoses 102 is connected to the two ends of the first fixed tube 101 respectively. There are two second fixed tubes 103, which are respectively arranged on two folding beams 4. One end of the two second fixed tubes 103 is connected to the other end of the two steel wire hoses 102 respectively. The crop dividing frame 11 is located in the middle part above the middle rotary disc cutting and discharging device 13, and one end is arranged on the upper suspension frame 1, and the other end is provided with a guide rod 12. The end of the crop dividing frame 11 close to the guide rod 12 is gradually inclined upward, and the guide rod 12 is shaped like an arrow.

[0051] The first fixing tube 101 is arranged on the upper suspension frame 1 through the first supporting member 21, and the first supporting member 21 includes a mounting seat 211 and a second mounting plate 212. The mounting seat 211 is arranged on the upper suspension frame 1, and a mounting groove is provided in the middle of the mounting seat 211. The second mounting plate 212 is arranged in the mounting groove, and the middle of the second mounting plate 212 is rotatably connected with the mounting seat 211. The first fixing tube 101 and the crop dividing frame 11 are both arranged at one end of the second mounting plate 212, and a plurality of first fixing holes 213 are arranged along an arc on the side wall of the mounting groove. The arc formed by the arrangement of the plurality of first fixing holes 213 takes the rotating shaft between the second mounting plate 212 and the mounting seat 211 as the center of the circle, and a second fixing hole is arranged at the other end of the second mounting plate 212. When the second mounting plate 212 rotates, the second fixing holes can respectively coincide with the plurality of first fixing holes 213, and the first mounting hole and the second mounting hole are fixed by a first fixing bolt;

[0052] The second fixed tube 103 is arranged on the folding beam 4 through the second support member 22. The second support member 22 includes an outer rod 221 and a telescopic rod 222. One end of the outer rod 221 is arranged on the flip frame. A mounting groove is arranged inside the outer rod 221. The telescopic rod 222 is movably arranged in the mounting groove, and one end is connected to the second fixed tube 103. A third fixing hole is arranged on the outer wall of the mounting groove. A plurality of fourth fixing holes are arranged on the telescopic rod 222 along its moving direction. As the telescopic rod 222 moves, the third fixing hole coincides with a fourth fixing hole and is fixed by a second fixing bolt.

[0053] The folding beam 4 is provided with a side guard plate 17, which is located on the side of the outer turntable cutting and diverting device 5 close to the upper suspension beam 1, that is, the rear side of the outer turntable cutting and diverting device 5, and the side guard plate 17 is connected to the main beam 2 through a connecting soft plate 19. The side guard plate 17 protects the outer turntable cutting and diverting device 5, and the connecting soft plate 19 is made of soft material and can be folded and twisted, which is conducive to the folding operation of the folding beam 4, thereby ensuring the normal operation of the folding beam 4, and having strong practicality.

[0054] The inner rotary disc cutting and dispensing device 3, the outer rotary disc cutting and dispensing device 5 and the middle rotary disc cutting and dispensing device 13 all include an upper mounting plate, a cutter disc assembly and a lower mounting plate. The cutter disc assembly is rotatably arranged between the upper mounting plate and the lower mounting plate. A circular groove co-centric with the cutter disc assembly is provided on the lower surface of the cutter disc assembly. A scraper 20 is arranged in the circular groove. A scraping surface is arranged at the edge of the scraper 20. The scraping surface is always in contact with the cutter disc assembly. When the cutter disc assembly rotates, the scraping surface of the scraper 20 scrapes off the attachments under the cutter disc assembly. This prevents weeds from being entangled and soiled under the cutter disc assembly, which affects the normal cutting work, or even causes vibration damage to the cutter disc assembly, thereby extending the service life of the cutter disc assembly.

[0055] In the working process of this embodiment, the folding beam 4 and the main cross beam 201 are in a straight line, and are connected to the power system of the harvester by a universal transmission shaft, and the cutter disc assembly of the inner turntable cutting and discharging device 3, the outer turntable cutting and discharging device 5 and the middle turntable cutting and discharging device 13 are driven to rotate together through various gear structures (the rotation direction is as follows Figure 1 ), so that the inner rotary cutting and dispensing device 3 and the outer rotary cutting and dispensing device 5 are harvested together as a group, and each middle rotary cutting and dispensing device 13 is harvested separately, which increases the overall harvesting width and increases the harvesting efficiency. The materials harvested by the inner rotary cutting and dispensing device 3 and the outer rotary cutting and dispensing device 5 enter the neutral tower wheel front guard guide 18 through the first material guide 15 and are introduced into the neutral tower wheel device 14, and then the materials are transported to the harvester through the neutral tower wheel device 14 and the rear tower wheel grass cleaning device and material guide device located on one side thereof; the materials harvested by the middle rotary cutting and dispensing device 13 are introduced into the neutral tower wheel device 14 through the second material guide 16, and then the materials are transported to the harvester through the neutral tower wheel device 14 and the rear tower wheel grass cleaning device and material guide device located on one side thereof, which is convenient for transportation and has strong practicality.

[0056] When not working, the oil cylinder 6 is controlled by the hydraulic system, so that the oil cylinder 6 drives the folding beam 4 and the outer rotary cutting and discharging device 5 thereon to fold upward, thereby reducing the width of the harvesting platform when walking, greatly reducing the occupied space, and walking stably and conveniently. The installation cylinder 31 and the first installation plate are arranged to facilitate the rotation connection of the rotating rod 7 on the inclined beam 202. The arrangement of the first connecting plate 8 realizes the hinged arrangement of the middle part of the cylinder body of the oil cylinder 6 and the inclined beam 202, which is convenient for installation. The cylinder body of the oil cylinder 6 is connected to the folding beam 4 through the second connecting plate 9, and the arrangement of the second connecting plate 9 realizes the rotation connection between the folding beam 4 and the main cross beam 201, which is conducive to ensuring the stability of the folding beam 4 during the folding and lifting process and the walking process of the harvester, reducing the load-bearing of the main beam 2 on the folding beam 4 and the outer rotary cutting and discharging device 5 thereon, and enhancing reliability.

[0057] The arc-shaped straw-gathering frame 10 is conducive to supporting the straws, and is separated into two ridges by the straw-dividing frame 11, which effectively prevents the stalks from falling forward and enhances the harvesting effect of the header. The straw-gathering frame 10 includes a first fixed pipe 101, a steel hose 102 and a second fixed pipe 103 connected in sequence, which is convenient for installation and replacement. The setting of the first fixed pipe 101 and the second fixed pipe 103 is conducive to the installation of the straw-gathering frame 10 on the upper suspension frame 1. The setting of the steel hose 102 not only supports the straws during operation, but also facilitates the normal folding operation of the folding beam 4, which is highly practical. The guide rod 12 at the front end of the straw-dividing frame 11 adopts an arrow-like shape, which is more convenient to separate the stalks between the two ridges. At the same time, the arrow shape of the head can effectively prevent the stalks from falling forward, and has a better effect of separating and collecting stalks than the traditional annular straw-dividing frame 11. In this way, when the stalks fall forward, the arrow on the head will prevent the stalks from falling to the ground, so that the arrow shape of the head intercepts the stalks, and one end of the crop dividing frame 11 close to the guide rod 12 is tilted upward, so that the stalks fall toward the direction of the tower wheel.

[0058] The first fixing tube 101 is lifted and arranged on the upper suspension frame 1 through the first supporting member 21, and the second fixing tube 103 is lifted and arranged on the folding beam 4 through the second supporting member 22. The specific operation process is: the second mounting plate 212 is rotated with the rotating shaft between the second mounting plate 212 and the mounting seat 211 as the center, so that the first fixing tube 101 and the grain dividing frame 11 on the second mounting plate 212 rise or fall to the required height, and then the second fixing hole and the first fixing hole 213 coincident therewith are fixed by the first fixing bolt. In addition, the telescopic rod 222 is pulled outward or retracted inward for a distance along the outer sleeve rod 221, so that the second fixing tube 103 is lifted and lowered to a certain position, and the third fixing hole and the fourth fixing hole coincident therewith are fixed by the second fixing bolt, that is, the height adjustment of the entire grain collecting frame 10 and the grain dividing frame 11 is completed, which is flexible and practical, is suitable for straws of different heights, is easy to adjust, and has strong practicality.

[0059] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
