Two guiding plates 4 are fixedly mounted on the front side of the strip-shaped box 1. The fixed knife 41 is fixedly mounted on one side of the two guiding plates 4 close to each other. The moving knife 42 is slidably mounted on the two guiding plates 4 and is adapted to the fixed knife 41;

[0031] An installation frame 61 is fixedly mounted on the top side of the strip-shaped box 1. A rotating rod 6 is rotatably mounted on the strip-shaped box 1. Conveyor rollers 62 are arranged on both the rotating rod 6 and the installation frame 61. The conveyor roller 62 on the rotating rod 6 is fixedly connected to the rotating rod 6. The conveyor roller 62 on the installation frame 61 is rotatably mounted on the installation frame 61. The two conveyor rollers 62 are in the same plane. The same conveyor belt 63 is drivingly connected between the two conveyor rollers 62, capable of controlling the conveyor roller 62 to drive the conveyor belt 63 to work when the rotating rod 6 rotates. A plurality of baffle plates 64 are fixedly mounted on one side of the conveyor belt 63 away from the conveyor roller 62, capable of better conveying the cut forage to one side of the strip-shaped box 1 when the conveyor belt 63 works. An installation block 43 is fixedly mounted on the top side of the moving knife 42. A guiding groove 431 is formed in the rear side of the installation block 43. A double-shaft motor 5 is fixedly mounted on the front inner wall of the strip-shaped box 1. A turntable 51 is fixedly mounted on the first output shaft of the double-shaft motor 5. A guiding pin 52 is fixedly mounted on the turntable 51.

[0032] In this embodiment, in order to control the rods 22 on different rotating shafts 21 of the same mounting base 2 to deflect synchronously in opposite directions when adjusting the position of the mounting base 2, so as to guide the forage in the forward direction of the forage harvester, and further enable the forage to reach the positions of the moving knife 42 and the fixed knife 41 under the guidance of the rods 22 for cutting operation, linkage gears 23 are fixedly sleeved on multiple rotating shafts 21, and two linkage gears 23 located on the same mounting base 2 are meshed with each other.

[0033] In this embodiment, in order to improve the accuracy of adjusting the positions of the two mounting bases 2 on both sides, the adjusting motor 31 is a servo motor.

[0034] Among them, both the moving knife 42 and the fixed knife 41 adopt serrated blades used in conventional forage harvesters.

[0035] For the circuits, electronic components involved, and the required module mechanisms for cooperation and use, etc., the existing technologies are adopted, and those skilled in the art can fully implement them without further elaboration. The content protected by this application does not involve improvements to software, circuits, and methods either.

[0036] Working principle: When the forage harvester is working, first install the two brackets 12 on the front side of the forage harvester and connect the strip-shaped box 1 with the adjusting part of the forage harvester. Then turn on the power supply, and adjust the strip-shaped box 1 to an appropriate height under the support and guidance of the brackets 12 and the sliders 11 through the adjusting part of the forage harvester to ensure that the moving knife 42 and the fixed knife 41 can perform cutting operations from an appropriate height position of the forage.

[0037] Next, start the adjusting motor 31 to drive the bidirectional lead screw 3 to rotate, and then adjust the positions of the two mounting bases 2 on both sides in the strip-shaped box 1, so as to adjust the distance between the rods 22 on both sides to meet the forage harvesting requirements of different widths.

[0038] During the forward movement of the forage harvester, the forage will gradually move closer to the position of the moving knife 42 under the guidance of the rods 22. At this time, start the double-shaft motor 5 to drive its first output shaft to drive the turntable 51 and the guide pin 52 to rotate, and then control the moving knife 42 to perform left-right reciprocating movement under the guidance of the guide groove 431, so that the moving knife 42 and the fixed knife 41 cooperate to cut the forage. At the same time, the second output shaft of the double-shaft motor 5 drives the rotating rod 6 and the conveying roller 62 to rotate through the meshing action of the bevel gear one 53 and the bevel gear two 54, and then controls the conveyor belt 63 to work, and conveys the cut forage to one side of the strip-shaped box 1 through the baffle 64, which is convenient for subsequent collection and processing.

[0039] In addition, since linkage gears 23 are fixedly sleeved on multiple rotating shafts 21, and two linkage gears 23 located on the same mounting base 2 are meshed with each other, when adjusting the position of the mounting base 2, the support rods 22 on different rotating shafts 21 on the same mounting base 2 can be controlled to deflect synchronously in opposite directions, so that the forage can be better guided, and then the forage can be gathered to the cutting positions of the moving knife 42 and the fixed knife 41.

[0040] In summary, the mowing head structure of the forage harvester proposed by the present utility model is reasonably designed, simple and convenient to operate, can realize efficient and accurate cutting and conveying of forage, improves the efficiency and quality of forage harvesting. At the same time, through the precise control of the adjusting motor 31 and the dual-shaft motor 5, and the meshing effect of the linkage gears 23, the adjusting precision and stability of the mowing head are further improved, making it more adaptable to the forage harvesting requirements of different widths and heights.

[0041] The above has introduced in detail a mowing head of a forage harvester provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
