Detailed Implementation

[0040] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. 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.

[0041] like Figures 1 to 14 As shown, an embodiment of this utility model provides a self-propelled Caragana korshinskii harvester, including: a frame 10 and a power unit 7. A walking device 4 is installed below the frame 10 for driving the frame 10 to move. A cab 5 is provided above the frame 10, and an operation control device is provided in the cab 5 for controlling the movement of the frame 10 and the operation of each mechanism. It also includes a header mechanism 1, a feeding mechanism 2, a chopping mechanism 3, and a throwing mechanism 6 connected sequentially from the front end to the rear end of the frame 10. The power unit 7 provides power for the operation of the header mechanism 1, the feeding mechanism 2, the chopping mechanism 3, and the throwing mechanism 6.

[0042] The header mechanism 1 includes: a header frame 11, a pair of cutters mounted on the header frame 11, and a weed guard assembly 15 disposed between the pair of cutters. Each cutter includes a vertically arranged rotating shaft 19, a saw disc 12 fixedly connected to the lower end of the rotating shaft 19, a saw disc drive pulley 18 fixedly connected to the upper end of the rotating shaft 19, and a weeding roller 13 coaxially connected to the rotating shaft 19 via a weeding roller bearing 32. The outer wall of the weeding roller 13 is provided with multiple sets of weeding blades 23 horizontally arranged along its axis. A weeding roller drive pulley 20 is provided on the weeding roller 13. Each set of weeding blades 23... 3 includes multiple blades of varying lengths, with adjacent rake blades 23 of the same cutter being staggered; the grass baffle assembly 15 includes a pair of symmetrically arranged grass baffles 24, one end of which is connected to the cutter frame 11, and the other end is provided with an arc-shaped plate extending from between the pair of cutters to both sides of the cutter. The grass baffle 24 has a gap at the position where the rotational movement of the rake blades 23 interferes with the grass baffle 24. When the rake blades 23 rotate to intersect with the arc-shaped plate of the grass baffle 24, the included angle α formed between the edge of the rake blades 23 and the arc-shaped plate is always greater than 80°.

[0043] Specifically, such as Figure 1 As shown, the overall workflow of the machine mainly involves the cutting mechanism 1 cutting shrubs such as Caragana korshinskii at high speed, feeding them to the feeding mechanism 2 via the rake roller 13, combing and compacting the Caragana korshinskii through the feeding mechanism 2, and then conveying them to the chopping mechanism 3. The chopping mechanism 3 simultaneously conveys the shrubs to the throwing mechanism 6 via an accelerating fan. After being accelerated by the throwing mechanism 6, the shrubs can be collected in a hopper or thrown to a following vehicle, depending on the actual situation. In one embodiment, the power unit 7 is an engine. The power unit 7 transmits power to the intermediate transition shaft, which has a first pulley and a second pulley, thus dividing the power into two sets of belt drives. One set of belt drives transmits power step-by-step to the chopping mechanism 3, the feeding mechanism 2, and the cutting mechanism 1. The other set of belt drives transmits power through a gearbox to the fan of the throwing mechanism 6, enabling the power unit 7 to drive each mechanism into operation.

[0044] Specifically, such as Figure 2 and Figure 3As shown, in this embodiment, the two ends of the rotating shaft 19 are connected to the header frame 11 via a pair of header bearings 21. The rotating shaft 19 is coaxially connected to the reeling roller 13 via a reeling bearing 22. The saw disc 12 is fixedly connected to the lower end of the rotating shaft 19, the saw disc drive pulley 18 is fixedly connected to the upper end of the rotating shaft, and the reeling roller drive pulley 20 is fixedly connected to the reeling roller 13. During operation, the sprocket on the feeding mechanism 2 is connected to the input sprocket of the header drive device 14 via chain drive. The output end of the header drive device 14 is provided with two pulleys of different sizes, which drive the saw disc drive pulley 18 and the reeling roller drive pulley 20 respectively. The header drive device 14 enables the saw disc 12 and the reeling roller 13 to rotate coaxially, in the same direction, and at different speeds via belt drive, so that cutting and reeling do not affect each other.

[0045] In this embodiment, as Figure 2 and Figure 13 As shown, the saw disc 12 is ≥30mm above the ground, and the stubble height meets the forestry requirements. The saw disc 12 is tilted in the forward direction, and the angle θ between it and the horizontal ground is 8-16°. The saw disc 12 is driven by a belt, which enables the linear speed of the saw disc 12 to reach 70m / s. By adjusting the cutting angle and cutting speed of the saw disc 12, the stubble cutting effect of shrubs can be improved, and the problem of shrub stubble damage can be solved.

[0046] like Figure 4 and Figure 12 As shown, the grass baffle assembly 15 is fixedly connected to the cutter frame 11. When the rake blade 23 rotates, the included angle α between the edge of the rake blade 23 and the grass baffle 24 is always greater than 80°, to prevent the two from trapping shrub branches and causing blockage during operation.

[0047] In this embodiment, as Figure 11 As shown, a polymer angle iron 25 is provided on the grass-blocking plate 24 near the feeding mechanism 2. The included angle β between the polymer angle iron 25 and the arc-shaped plate of the grass-blocking plate 24 is 20-45°. This serves to gather the shrub branches towards the center when they enter the feeding mechanism 2, preventing the branches from getting stuck in the feeding mechanism. The maximum rotation diameter of the rake blade 23 is 10-30mm smaller than the rotation diameter of the saw disc 12, to prevent the rake blade 23 from breaking the shrub branches before they are cut during operation.

[0048] In this embodiment, as Figure 2 As shown, it also includes a gathering rod 16, which is disposed at the front end of the cutter and is fixedly connected to the cutter frame 11. The gathering rod 16 can pick up and gather fallen shrubs; in this embodiment, as Figure 14As shown, the bottom of the aggregation rod 16 is provided with an aggregation adjustment rod 17. One end of the aggregation adjustment rod 17 is hinged to the aggregation rod 16, and the other end is hinged to the cutter frame 11. The hinged end of the aggregation adjustment rod 17 and the aggregation rod 16 is provided with multiple adjustment holes. By adjusting the hinged position of the aggregation rod 16 and the multiple adjustment holes, the height of the aggregation rod 16 can be adjusted to adapt to the gathering and harvesting of shrubs of different heights.

[0049] In this embodiment, as Figure 5 As shown, the discharge port of the cutting mechanism 1 is connected to the inlet of the feeding mechanism 2. The feeding mechanism 2 includes: a feeding housing located at the rear end of the cutting mechanism 1, a first set of feeding rollers 26 and a second set of feeding rollers 27 mounted on the feeding housing. The feeding rollers are connected to the feeding housing via a feeding shaft. Each set of feeding rollers includes an upper feeding roller and a lower feeding roller. A downward-stretching tension spring connects the upper feeding roller to the feeding housing, allowing the upper feeding roller to float up and down, thus compacting the material. The outer circumference of the feeding roller is provided with multiple racks arranged along its axial direction. The feeding drive pulley is mounted on the feeding housing and connected to the feeding shaft, thereby driving the upper and lower feeding rollers of each set of feeding rollers to rotate relative to each other simultaneously. The power unit 7 is connected to the feeding drive pulley via belt drive, driving the first set of feeding rollers 26 and the second set of feeding rollers 27 to compact and comb the material before feeding it into the chopping mechanism. Specifically, by using aggregate angle iron, the shrub branches are drawn together towards the center when they enter the feeding mechanism 2, preventing them from getting stuck in the gap between the feeding roller and the feeding housing. The feeding roller is equipped with a toothed rack, and in each set of feeding rollers, the upper feeding roller is fixed with a tension spring, which can compact and comb the shrub branches, facilitating subsequent cutting.

[0050] In this embodiment, as Figure 6 and Figure 7As shown, the discharge port of the feeding mechanism 2 is connected to the inlet of the chopping mechanism 3. The chopping mechanism 3 includes: a chopping housing 34, a chopping shaft 33, a moving chopping drum 38, a fixed blade 37, and a chopping drive pulley 31. The chopping shaft 33 is horizontally installed inside the chopping housing 34. The moving chopping drum 38 is mounted on the chopping shaft 33. The fixed blade 37 is positioned on the chopping housing 37 corresponding to the moving chopping drum 38. The moving chopping drum 38 rotates relative to the fixed blade 37 to chop the material. The chopping drive pulley... The shredder 31 is located on the outside of the shredding housing 34 and connected to the shredding shaft 33. The power unit 7 is connected to the shredding drive pulley 31 via belt drive. A limiting claw 35 is located at the bottom of the shredding housing 34. One end of the limiting claw 35 is connected to the shredding housing 34, and the other end is connected to the feeding housing of the feeding mechanism 2. A material discharge port is located at the bottom of the shredding housing 34, and a material discharge plate 36 is located at the discharge port. One side of the material discharge plate 36 is hinged to the shredding housing 34, and the other side is detachably connected to the shredding housing 34. Specifically, the limiting claw 35 of the shredding mechanism 3 is connected to the feeding mechanism 2 to prevent the feeding mechanism 2 from disengaging, and the handle of the limiting claw 35 is also convenient for user operation. The material discharge plate 36 is hinged to the shredding housing 34 on one side. If blockage occurs, loosening the bolt on one side will remove the accumulated material inside the shredding mechanism 3. This reduces the user's maintenance workload and saves time.

[0051] In this embodiment, as Figure 6 As shown, the moving blade chopping drum 38 includes a moving blade support frame, a left moving blade seat assembly, and a right moving blade seat assembly. The moving blade support frame is sleeved on the middle section of the chopping blade shaft 33. The left power frame assembly and the right moving blade seat assembly are evenly arranged on the left and right sides of the moving blade support frame along the circumference of the chopping blade shaft 33, respectively. One end of the left power frame assembly and the right moving blade seat assembly is connected to the chopping shell 34, and the other end is connected to the moving blade support frame. The left power frame assembly and the right moving blade seat assembly each include multiple moving blade supports distributed circumferentially. The moving blade supports of the left power frame assembly and the moving blades of the right moving blade seat assembly are staggered with each other. The chopping shell 34 is mounted on the frame 10 behind the feeding mechanism 2 through the support seat 33.

[0052] In this embodiment, as Figure 8 and Figure 9The discharge port of the chopping mechanism 3 is connected to the inlet of the throwing mechanism 6. The throwing mechanism 6 includes an accelerating blower 61 and a throwing arm 63 connected to the accelerating blower. The accelerating blower 61 is connected to the power unit 7 via belt drive. The bottom of the throwing arm 63 is equipped with a throwing arm turntable controlled by a hydraulic system. The lower part of the throwing arm 63 is hinged to a hydraulic lifting cylinder, and the pitch angle of the throwing arm 63 is controlled by the hydraulic system. One end of the throwing arm 63 is equipped with a throwing inlet, and the other end is equipped with a throwing outlet. The throwing inlet is connected to the discharge port of the accelerating blower. The lower middle section of the throwing arm is equipped with a cutting end, and a cutting baffle 67 is provided at the cutting end. One end of the cutting baffle 67 is equipped with a hinge handle 70. The hinge handle 70 is connected to the hinge point of the throwing arm 63. The cutting baffle 67 is connected to the cutting baffle operating mechanism through the hinge handle 70. The cutting baffle operating mechanism includes a straight connecting rod 69, an L-shaped connecting rod 68, and a cutting baffle operating lever 64. One end of the straight connecting rod 69 is hinged to the hinge handle 70, and the other end is connected to one end of the L-shaped connecting rod 69. The cutting baffle operating lever 64 is hinged to the other end of the L-shaped connecting rod 68. The bend of the L-shaped connecting rod 68 is hinged to the throwing arm 63. By pulling the cutting baffle operating lever 64, the L-shaped connecting rod 68 is rotated around the bend, causing the straight connecting rod 69 to move, thereby causing the cutting baffle 67 to rotate around the hinge point, thus controlling the opening and closing of the cutting baffle 67 at the cutting point.

[0053] Specifically, such as Figure 8 and Figure 9 As shown, the material is shredded by the chopping mechanism 3 and then conveyed to the throwing mechanism 6. After being accelerated by the accelerating fan 61, it is thrown by the throwing arm 63 into the collection box 9 or behind the following vehicle. The cutting baffle control lever 64 is fixedly connected to the throwing arm 63. The cutting baffle 67 is simultaneously hinged to the throwing arm 63 and the straight connecting rod 69. The L-shaped connecting rod 68 is simultaneously hinged to the throwing arm 63 and the straight connecting rod 69. The cutting baffle control lever 64 is connected to the L-shaped connecting rod through a flexible shaft, which can drive the L-shaped connecting rod to move. The user can operate the cutting baffle control lever 64 to switch the working mode of the throwing arm 63. When switching the working mode of the cutting baffle 67, the L-shaped connecting rod 68 drives the cutting baffle 67 to rotate around the hinge point through the straight connecting rod 69, thereby switching the working mode of the throwing arm 63. The user can operate the cutting baffle operating lever 64 to change the working position of the cutting baffle 633 to switch the working mode. When the cutting baffle 67 is attached to the upper surface of the throwing arm 63, the cutting opening is opened and the material enters the collection box 9. When the cutting baffle 67 is attached to the lower surface of the throwing arm 63, the cutting opening is closed and the material is thrown by the throwing arm 63 and the throwing head 66 to the following vehicle.

[0054] In this embodiment, as Figure 10As shown, a material collection box support 8 is provided at the rear end of the frame 10. The material collection box support 8 is hinged to the material collection box 9. The material collection box 9 is located below the cut-off opening of the throwing arm 63. A lifting cylinder is provided on the material collection box support 8. The piston of the lifting cylinder is hinged to the material collection box 9 to realize the tilting of the material collection box 9. The material collection box support 8 is hinged to the material collection box 9. When the material collection box 9 is full of material, the material collection box 9 can be tilted by lifting the cylinder.

[0055] In this embodiment, as Figure 10 As shown, the collection box 9 has three baffles connected in sequence around its circumference. Each baffle has a foldable plate on its upper part, namely the first foldable plate 91, the second foldable plate 92, and the third foldable plate 93, which are hinged to the baffles. When the machine needs to be transported, the first foldable plate 91, the second foldable plate 92, and the third foldable plate 93 can be folded respectively, and the throwing arm 63 can be lowered, thereby reducing the overall height of the machine. This operation reduces the overall transport height of the machine, making it easier to transport.

[0056] In this embodiment, as Figure 11 As shown, when the collection box 9 needs to be flipped up for maintenance, the support rod 81, which is hinged to the collection box bracket 8, supports the crossbeam on the collection box 9, which can prevent the collection box from falling accidentally.

[0057] In this embodiment, as Figure 8 As shown, the discharge port of the throwing arm 63 is equipped with a throwing head 66. One end of the throwing head 66 is hinged to the throwing arm 63, and the other end of the throwing head 66 is connected to the hydraulic rod of the throwing head cylinder 65. The tilting angle of the throwing head 66 is controlled by the throwing head cylinder 65. When the material is thrown to the following vehicle, the throwing head cylinder 65 controls the throwing head 66 to adjust the throwing distance of the material.

[0058] like Figures 1-14 As shown, in this embodiment of the self-propelled Caragana korshinskii harvester, during operation: the power unit 7 drives the header mechanism 1, the feeding mechanism 2, the shredding mechanism 3, and the throwing mechanism 6 through belts and chains. At the same time, the power unit 7 drives the chassis drive components through belts, causing the frame 10 to move forward.

[0059] The saw disc 11 of the cutting platform mechanism cuts the shrub branches. Under the combined action of the rake roller 13 and the grass-blocking plate assembly 15, the shrub branches are transported to the feeding mechanism 2. After being compacted and combed by multiple sets of feeding rollers, they are transported to the chopping mechanism 3.

[0060] The shredding mechanism 3's shredding shaft 33 rotates at high speed. Under the combined action of the moving shredding drum 38 and the fixed blade 37, the shrub branches are shredded to the designed length. At the same time, the shredded material is thrown by the shredding shaft 33 to the acceleration fan 61. After being accelerated by the acceleration fan 61, it is thrown by the throwing arm 63 to the collection box 9 or to follow the vehicle.

[0061] When the throwing position needs to be adjusted, the hydraulic system controls the left and right rotation of the throwing arm turntable 62 and the pitch angle of the throwing arm 63, as well as the tilt angle of the throwing head 66, to change the throwing direction and height of the material.

[0062] When material gets stuck in the shredding mechanism 3, the user can unscrew the bolts securing the feed plate 36 to clear the debris. If the user needs to disassemble the feeding mechanism 3 from the machine, loosen the limit claw 35 and then loosen the upper fixing bolts to disassemble the feeding mechanism 3.

[0063] When users need to transport vehicles or pass through roads with height restrictions, they can fold the foldable plate installed on the aggregate box 9 and lower the throwing arm 63 to the lowest point to pass through roads with height restrictions that are no lower than the cab.

[0064] 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.
