Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0044] like Figures 1 to 13As shown, an embodiment of this utility model provides a harvesting header device for Caragana korshinskii, including: a header frame 4; a pair of cutters 5, the pair of cutters 5 being symmetrically installed on the header frame 4, each cutter 5 including a vertically arranged saw disc drive shaft 35, a saw disc device 7 installed at the lower end of the saw disc drive shaft 35, and a saw disc drive wheel 12 installed at the upper end of the saw disc drive shaft 35, the left and right saw disc devices 7 being staggered to form an overlapping area; a primary feeding mechanism 9, including a pair of symmetrically arranged reeling rollers, each reeling roller including: a reeling roller shaft 25 coaxially installed on the saw disc drive shaft 35, and a reeling drive wheel 11 connected to the reeling roller shaft 25, so as to... The feeding mechanism 9 includes a feeding roller 26 installed outside the feeding roller shaft 25. The outer wall of the feeding roller 26 is provided with multiple sets of feeding blades 27 arranged horizontally along its axis. Each set of feeding blades 27 includes multiple blades. Adjacent feeding blades 27 of the same primary feeding mechanism 9 are staggered. The secondary feeding mechanism 6 is located behind the primary feeding mechanism 9 and includes a pair of feeding rollers arranged symmetrically on the left and right. The feeding rollers include a vertically arranged feeding shaft 20, multiple sets of feeding blades 21 arranged on the feeding shaft 20, and a feeding drive wheel 18 connected to the feeding shaft 20. The multiple sets of feeding blades 21 are arranged horizontally along the axis of the feeding shaft 20.

[0045] Specifically, such as Figure 1 and Figure 6 As shown, in this embodiment, the cutter 5 is connected to the header frame 4 via a main bearing 34. Washers are provided between each drive wheel to adjust the axial position. The main bearing 34 is located below the reeling drive wheel 11 and the saw blade drive wheel 12, facilitating easy replacement of the upper wear parts. The reeling roller shaft 25 is coaxially connected to the saw disc drive shaft 35 via a pair of transition bearings 33. The lower end of the saw disc 30 and the saw disc drive shaft 35 is fixedly connected via an anti-winding saw disc wheel 29. The upper end of the saw disc drive wheel 12 and the saw disc drive shaft 35 is fixedly connected via a double-hole pressure cap 36. The reeling drive wheel 11 and the reeling roller shaft 25 are fixedly connected via a bearing seat connecting plate 23. Figure 4 As shown, the left and right saw blade devices 7 are staggered vertically with a height difference of 5-10mm, forming an overlapping area that enables seamless cutting within the cutting area. The cut strips are fed into the next process step by step through the primary feeding mechanism 9 and the secondary feeding mechanism 6, improving feeding efficiency and preventing the cutting table from clogging due to uneven feeding.

[0046] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the Caragana korshinskii harvesting header device also includes left and right gearboxes 16, located at the rear of the header frame 4. The gearboxes 16 have a main shaft 22 and a drive sprocket. The main shaft 22 has a reeling drive wheel 15, a saw disc drive wheel 14, and a feeding drive wheel 12. The reeling drive wheel 15, the saw disc drive wheel 14, and the feeding drive wheel 12 are respectively connected to the reeling drive wheel 11, the saw disc drive wheel 12, and the feeding drive wheel 18 via belt drives. The drive sprockets input power to the main shaft 22 via chain drives. The Caragana korshinskii harvesting header device also includes a main drive tensioning device 3, located at the lower part of the gearboxes 16, used to tension the chain of the chain drive. As an example, the main drive tensioning device 3 consists of a support arm, a tensioning wheel, and a tensioning wheel pull rod device; the tensioning pull rod device consists of a pull rod, a buffer spring pad, etc.

[0047] Specifically, such as Figure 2 and Figure 3 As shown, within the load-bearing range of the gearbox, different speed ratios can be achieved between the saw disc device 7, the primary feeding mechanism 9, and the secondary feeding mechanism 6 by adjusting the speed ratios between the drive wheels, thus adapting to different crops. Within a certain speed range, the input speed of the main drive is also variable, allowing for adjustments to various cutting speeds. During operation, the main shaft 22 has pulleys of different sizes on the reeling drive wheel 15, the saw disc drive wheel 14, and the feeding drive wheel 13, which drive the saw disc drive wheel 12 and the reeling drive wheel 11 respectively. Through belt transmission, the saw disc device 7, the reeling roller shaft 25, and the feeding shaft 20 rotate coaxially, in the same direction, and at different speeds, ensuring that cutting and feeding do not interfere with each other. As an example, the upper part of the header frame 4 is equipped with a protective cover to protect the drive wheels, drive wheels, and belt drives.

[0048] As an example, such as Figure 2 and Figure 3 As shown, the top of the header frame is provided with a pair of mounting holes 10, and the bottom of the header frame 4 is provided with a pair of mounting and fixing holes 17. The header frame is connected to the whole machine of the harvester through the mounting holes 10 and the mounting and fixing holes 17.

[0049] In this embodiment, as Figure 6 As shown, the reeling roller 26 is provided with an upper roller cover plate 24 and a lower roller plate 32. The reeling roller 26 is connected to the reeling roller shaft 25 through the upper roller cover plate 24. The transition bearing 33 includes a first transition bearing and a second transition bearing. The lower roller cover plate 32 is connected to the saw disc drive shaft 35 through the first transition bearing. The reeling drive wheel 11 is coaxially connected to the saw disc drive shaft 35 through the second transition bearing. As an example, both the upper roller cover plate 24 and the lower roller plate 32 are provided with reinforcing ribs 37 to improve the strength of the reeling roller 26.

[0050] In this embodiment, as Figure 6 and Figure 7As shown, the saw disc device 7 includes an anti-winding saw disc wheel 29, a saw disc 30, and a saw blade 28 connected in sequence. The anti-winding saw disc wheel 29 is connected to the saw disc drive shaft 35. The saw disc 30 includes a first horizontal section, a conical section 31, and a second horizontal section connected in sequence from top to bottom. The first horizontal section is connected to the anti-winding saw disc wheel 29, and the second horizontal section is connected to the saw blade. The saw blade 28 is composed of multiple saw segments 41 spliced ​​together along the edge of the saw disc. Specifically, the conical section 31 of the saw disc 30 can increase the strength of the saw disc 30, making it less prone to deformation, and the saw disc 30 is less likely to jam or entangle materials, thus improving the overall cutting stability of the saw disc 30.

[0051] In this embodiment, as Figure 6 and Figure 7 As shown, the anti-tangle saw wheel 29 includes: a saw wheel hub 38 connected to the saw wheel drive shaft 35 and a connecting disc 39 disposed on the outer ring of the saw wheel hub 38. The connecting disc 39 is connected to the saw wheel 30. An anti-tangle ring 40 is provided on the outer ring of the connecting disc 39. The cutting table frame 4 is provided with a bearing seat 50 connected to the bottom of the saw wheel drive shaft 12. A Z-shaped labyrinth gap is formed between the anti-tangle ring 40 and the bearing seat 50. Figure 13 As shown, specifically, the bearing seat 50 is connected to the cutter frame 4, the bearing inside the bearing seat 50 is coaxially connected to the saw disc drive shaft 35, and the gap between the anti-winding ring 40 and the bearing seat 50 forms a Z-shaped labyrinth gap, which has a dustproof effect and prevents weeds and small twigs from getting tangled with the saw disc hub 38.

[0052] In this embodiment, as Figure 12 As shown, the saw disc 30 is tilted in the forward direction, with an angle θ of 8-16° between it and the horizontal ground, thereby improving the stubble cutting effect of shrubs and avoiding damage to the shrub stubble.

[0053] In this embodiment, the adjacent reeling blades 27 and the feeding blades 21 are staggered vertically with an overlap distance of 100mm, which can better achieve uniform feeding transition.

[0054] In this embodiment, as Figure 4 As shown, adjacent blades of the same cutter are staggered and distributed in a 15° counter-rotation direction. Specifically, after the crop is cut, the bottom of the stalks enters the primary feeding mechanism first under the action of the push rod. The blades of the primary feeding mechanism are distributed in a 15° counter-rotation direction, which facilitates smooth feeding by the primary feeding mechanism.

[0055] As an example, such as Figure 4 As shown, baffles 19 are symmetrically arranged between the feed shafts 20. One end of the baffle 19 is connected to the cutter frame 4, and the other end extends to both sides of the feed shaft 20. The surface of the baffle 19 has gaps at the interference points between it and the feed blade 21 when it rotates, which can prevent the bar from getting tangled and blocked during the feeding process.

[0056] In this embodiment, as Figure 1 and Figure 11 As shown, it also includes a gathering device 2, which is located at the front end of the cutter 5 and serves to gather the shrubs. The gathering device 2 includes a support base 47 and a gathering rod 44. The gathering rod 44 is connected to the cutter frame 4 via the support base 47. The front end of the gathering rod 44 is provided with an extension rod 45, and the rear end of the gathering rod 45 is provided with a support rod 48. One end of the support rod 48 is hinged to the gathering rod 44, and the other end is hinged to the cutter frame 4. The hinged end of the support rod 48 and the gathering rod 44 is provided with multiple adjustment holes. By adjusting the hinge position of the gathering rod 44 and the multiple adjustment holes, the height of the gathering rod 44 can be adjusted. Specifically, by adding an extension rod 45 to the front end of the gathering rod 44, the crops scattered on both sides can be gathered together. A push rod 46 is located between the rear ends of a pair of gathering rods 44. One end of the support rod 48 is hinged to the push rod 46 at the rear end of the gathering rod 44, and the other end is hinged to the support base 47. The push rod 46 provides support. Figure 2 As shown, as an example, the polymerization device 2 also includes a cutting table protection net 49, which is disposed on the upper part of the cutting table frame 4. The cutting table protection net 49 is welded from a metal frame and a metal mesh, and is used to prevent the cut strips from overflowing from the upper part of the cutting table frame 4.

[0057] In this embodiment, as Figure 1 and Figure 10 As shown, floating sliding devices 8 are provided at the front ends of both side walls of the header frame 4. The floating sliding device 8 includes a triangular support housing 42 and a hinge part 43. The hinge part 43 is hinged to the end of the side wall of the header frame 4, and the tip of the triangular support housing 42 is located at the end of the side wall of the header frame 4. The floating sliding device 8 is hinged to the front ends of both side walls of the header frame 4, and is generally placed on the ground or suspended in the air. If it encounters obstacles such as mounds of soil, it can be lifted up, thus conforming to the terrain and supporting lodged crops, thereby reducing the rate of missed harvesting.

[0058] The working principle of the Caragana korshinskii harvesting header device in this embodiment is as follows: external power is transmitted to the main shaft 22 of the gearbox 16 via chain drive, and the power is divided into three parts via belt drive. The first part is used to drive the saw disc drive wheel 12, thereby transmitting power to the saw disc device 7 to provide power for the rotation and cutting of the saw disc device 7. The second part is used to drive the reeling drive wheel 11, transmitting power to the reeling roller 26. Through the rotation of the reeling blades 27, the cut Caragana korshinskii is fed from the primary feeding mechanism 9 to the secondary feeding mechanism 6. The third part is used to drive the feeding drive wheel 18, transmitting power to the feeding shaft 20. The feeding blades 21 on the feeding shaft 20 further transfer the Caragana korshinskii conveyed by the secondary feeding mechanism 6 to the next process.

[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
