Description

Technical Field

[0001] The utility model relates to a harvester, in particular to a broad-leaved forage harvester. Background Art

[0002] Common broad-leaved forage harvesters are mainly divided into three types according to the type of cutting knives, namely circular saw blade type, reciprocating moving knife type and rope flinging type. Among them, the circular saw blade type has a hand-pushed harvester type and a traction harvester type, which are suitable for harvesting large-area or small-area forage; due to structural reasons, the reciprocating moving knife type is generally manufactured as a traction harvester and is suitable for harvesting large-area forage; the rope flinging type harvester is generally a hand-held harvester and is suitable for small-area harvesting. Since the cutting tools of the circular saw blade type or the reciprocating moving knife type are of rigid structure and have poor flexibility, encountering uneven terrain or stones in the land will damage the tool structure.

[0003] Therefore, it is necessary to design a rope flinging type harvester that can be used for large-area forage harvesting. Summary of the Utility Model

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a broad-leaved forage harvester to improve the adaptability of the machine to the terrain.

[0005] To achieve the above object, a broad-leaved forage harvester disclosed by the utility model includes a frame, and the frame is fixedly connected to a suspension for connecting a tractor;

[0006] A first cutting machine, the first cutting machine includes a driver, a housing, a rotating shaft and a wire box. The driver is fixedly connected to the housing. The rotating shaft is rotatably connected to the housing and is connected to the output end of the driver through a belt drive. The wire box is connected to the end of the rotating shaft and is arranged below the housing. The wire box is provided with at least one rope.

[0007] Preferably, the frame includes a main frame and auxiliary frames. The auxiliary frames are disposed on both sides of the main frame. The auxiliary frames are hinged to the main frame. An expansion rod is arranged between the main frame and the auxiliary frames. One end of the expansion rod is hinged to the main frame, and the other end of the expansion rod is hinged to the auxiliary frame.

[0008] Preferably, it further includes a second cutting machine, and the second cutting machine corresponds to the auxiliary frame one by one and is fixedly connected to the auxiliary frame.

[0009] Preferably, the second cutting machine includes a housing, a rotating shaft and a wire box. The rotating shaft is rotatably connected to the housing. The wire box is arranged below the housing and is fixedly connected to the rotating shaft.

[0010] Preferably, one end of the rotating shaft in the second cutting machine that extends above the housing is connected to a first pulley, and one end of the rotating shaft in the first cutting machine that extends above the housing is connected to a second pulley. A belt is connected between the first pulley and the second pulley.

[0011] Preferably, the suspension includes four vertical rods. The bottom ends of the four vertical rods are connected to the four corners of the main frame in a rectangular distribution, and the top ends of the four vertical rods are fixed to each other.

[0012] The utility model has the following technical effects:

[0013] 1. In this device, the wire box drives the whipping rope to rotate at a high speed to cut broad-leaved forage grass, and then the hay rake and baler are used to complete the storage of green grass. Since the whipping rope has high flexibility, it has higher adaptability to terrain compared with the existing circular saw blade harvester and reciprocating moving blade harvester.

[0014] 2. This device can be connected to the towing frame through the suspension to achieve high-speed and large-area forage grass harvesting, with high harvesting efficiency.

[0015] 3. The harvesting width can be adjusted through the telescopic rod. When the harvesting width needs to be adjusted, first remove the belt between the first cutting machine and the second cutting machine; then adjust the telescopic rod to the appropriate position; then select a belt of appropriate length according to the distance between the first pulley and the second pulley after adjusting the width; finally, adjust the length of the whipping rope, and the structure is flexible.

There is one main frame 10 and two auxiliary frames 11. The two auxiliary frames 11 are respectively arranged on both sides of the main frame 10. The two auxiliary frames 11 are respectively connected to the main frame 10 through pin shafts to form a hinge point (refer to point A in the appendix Figure 2 ), so that the auxiliary frame 11 and the main frame 10 form a hinge. At the same time, a telescopic rod 12 is provided between the main frame 10 and the auxiliary frame 11. One end of the telescopic rod 12 is hinged to the main frame 10, and the other end of the telescopic rod 12 is hinged to the auxiliary frame 11. When the telescopic rod 12 extends or contracts, the auxiliary frame 11 can rotate around point A (refer to the arrow direction in the appendix Figure 2 ), realizing the change of the forage harvesting width. Refer to appendix Figure 2 and appendix Figure 5 to compare the change in the harvesting width before and after. Figure 2 and Figure 5 The circular lines in represent the cutting width of each throwing rope; the harvesting width in appendix Figure 2 is X, and the harvesting width in appendix Figure 5 is Y. In one embodiment, the telescopic rod 12 can be a hydraulic cylinder; in another embodiment, the telescopic rod 12 can be an existing mechanical telescopic rod.
