[0036] Embodiment 1

[0037] The cutting and discharging device provided by the present application can be applied to a harvester, facilitating the switching of the working state of the harvester to a grass cutting state or a grass discharging state.

[0038] See Figures 1 to 4 As shown, the cutting and discharging device provided by the present application includes a housing 101, a shredder 102, and a switching mechanism 103. The housing 101 forms a material guiding channel 104, and the shredder 102 is located at the end of the material guiding channel 104; the housing 101 is provided with a discharging port 105, and on the material flow path, the discharging port 105 is located upstream of the shredder 102; the switching mechanism 103 includes a guide plate 106, the guide plate 106 is located at the discharging port 105, and the guide plate 106 can be flipped relative to the housing 101 within the material guiding channel 104 so that the guide plate 106 is flipped to a first position or a second position; the guide plate 106 in the first position blocks the discharging port 105, and the guide plate 106 in the second position blocks the shredder 102 and opens the discharging port 105.

[0039] Specifically, the cutting and discharging device includes a housing 101, a shredder 102, and a switching mechanism 103. Among them, the housing 101 is connected to the main body of the harvester, and the housing 101 encloses to form a material guiding channel 104, and the grains from the main body can flow from the starting end to the ending end of the material guiding channel 104 ( Figure 1 and Figure 2The arrow in it shows the flow direction of the grains). The chopper 102 is installed inside the housing 101 and at the end of the material guiding channel 104. When the grains flow to the chopper 102, the chopper 102 can chop the grains.

[0040] A discharge port 105 is also provided on the material guiding channel 104, and in the flow path of the material, the discharge port 105 is located upstream of the chopper 102. When the harvester is in the grass cutting state, the guide plate 106 flips to the first position to block the discharge port 105 to prevent the grains from leaking out of the discharge port 105. The grains can then flow along the material guiding channel 104 to the end, so that the chopper 102 can chop the grains. When the harvester is in the grass discharging state, the guide plate 106 flips to the second position to open the discharge port 105, so that the grains can be discharged from the discharge port 105. And the guide plate 106 can block the chopper 102 to cut off the material guiding channel 104, preventing the grains from flowing to the chopper 102, so that all the grains are discharged from the discharge port 105.

[0041] The cutting and discharging device provided in this application can quickly switch the harvester between the grass cutting and grass discharging working states by controlling the flipping position of the guide plate 106. The operation is simple and reliable, and the working efficiency of the harvester can be improved.

[0042] In an optional solution of this embodiment, the guide plate 106 in the second position is inclined to guide the material to the discharge port 105.

[0043] In this embodiment, as Figure 1 and Figure 2 shown, the fixed end of the guide plate 106 is located on the side of the discharge port 105 close to the chopper 102 and can flip inside the material guiding channel 104. When the harvester is in the grass discharging state, the guide plate 106 flips in the grain flow direction to block the cutter. And the plate area of the guide plate 106 is larger than the cross-sectional area of the guide plate 106. When the guide plate 106 flips to the second position, the movable end of the guide plate 106 abuts against the inner wall of the material guiding channel 104 and is inclined. At this time, the guide plate 106 forms an acute angle with the grain flow direction. When the grains flow to the guide plate 106, the guide plate 106 can guide the grains to the discharge port 105 to prevent the grains from accumulating at the guide plate 106.

[0044] In an optional solution of this embodiment, the switching mechanism 103 includes an operating component 107. The operating component 107 is located outside the housing 101, and the operating component 107 is connected to the guide plate 106 so that the operating component 107 and the guide plate 106 are linked. The operator can drive the operating component 107 to swing from the outside of the equipment to drive the internal guide plate 106 to swing, which is convenient for switching the working state of the harvester.

[0045] In an alternative embodiment of this example, as Figure 3 and Figure 4 shown, the switching mechanism 103 further includes a fixed disk 108. A connecting shaft 109 is provided between the operating component 107 and the material guiding plate 106. The operating component 107 can be connected to the material guiding plate 106 through the connecting shaft 109, and the connecting shaft 109 is rotatably installed on the fixed disk 108 so that the material guiding plate 106 and the operating component 107 can swing relative to the fixed disk 108. Preferably, the connecting shaft 109 penetrates through the fixed disk 108. The material guiding plate 106 is located inside the fixed disk 108, and the material guiding plate 106 is connected to one end of the connecting shaft 109. The operating component 107 is located outside the fixed disk 108, and the operating component 107 is connected to the other end of the connecting shaft 109.

[0046] In addition, the fixed disk 108 is installed on the housing 101. Specifically, the fixed disk 108 can be welded to the housing 101, and the connecting shaft 109 penetrates through the housing 101 to connect to the internal material guiding plate 106. The fixed disk 108 is provided with a first positioning structure and a second positioning structure, and the first positioning structure and the second positioning structure are located on the swinging path of the operating component 107 to be detachably connected to the operating component 107. When the operating component 107 swings to the first positioning structure, the material guiding plate 106 flips to the first position. At this time, the operating component 107 can be connected to the first positioning structure to position the operating component 107, so that the material guiding plate 106 is held in the first position. When the operating component 107 swings to the second positioning structure, the material guiding plate 106 flips to the second position. At this time, the operating component 107 can be connected to the second positioning structure to position the operating component 107, so that the material guiding plate 106 is held in the second position.

[0047] In an alternative embodiment of this example, the switching mechanism 103 further includes a plugging component 112. Specifically, as Figure 3 and Figure 4 shown, the first positioning structure is a first positioning hole 110 opened on the fixed disk 108. When the operating component 107 swings to the first positioning structure, the plugging component 112 can be inserted into the first positioning hole 110 to position the operating component 107. The second positioning structure is a second positioning hole 111 opened on the fixed disk 108. When the operating component 107 swings to the second positioning structure, the plugging component 112 can be inserted into the second positioning hole 111 to position the operating component 107.

[0048] Preferably, the first positioning hole 110 and the second positioning hole 111 are waist-shaped holes. The swinging trajectory of the operating component 107 forms a preset circle, and the length direction of the first positioning hole 110 and the second positioning hole 111 is the radial direction of the preset circle. When inserting the plugging component 112 into the first positioning hole 110 and the second positioning hole 111, the structure of the waist-shaped hole provides a margin space for the plugging component 112, which is convenient for inserting the plugging component 112 into the waist-shaped hole.

[0049] In an alternative solution of this embodiment, the plugging component 112 includes a plugging member and an elastic member. The elastic member is installed between the plugging member and the fixed plate 108 so that the plugging member has a tendency to insert into the first positioning hole 110 and the second positioning hole 111.

[0050] Preferably, the plugging component 112 further includes a pull ring which is connected to the plugging member.

[0051] In this embodiment, during the process of the manipulation component 107 swinging relative to the fixed plate 108, when the manipulation component 107 swings to the first positioning hole 110 or the second positioning hole 111, the elastic force exerted on the plugging member by the elastic member can cause the plugging member to insert into the first positioning hole 110 or the second positioning hole 111, preventing the plugging member from disengaging from the first positioning hole 110 or the second positioning hole 111, thereby realizing the position locking of the material guiding plate 106; when switching the position of the material guiding plate 106, pull the pull ring to enable the plugging member to disengage from the first positioning hole 110 or the second positioning hole 111, and then drive the manipulation component 107 to swing. When the manipulation component 107 swings between the first positioning hole 110 and the second positioning hole 111, the elastic member can be compressed so that the plugging member can slide on the surface of the fixed plate 108.

[0054] See Figure 3 and Figure 4 As shown in [relevant figures], in an alternative solution of this embodiment, an arc-shaped guide rail 113 is provided between the fixed plate 108 and the manipulation component 107 to guide the movement of the manipulation component 107, so that the flipping movement of the material guiding plate 106 is more stable.

[0055] In an alternative solution of this embodiment, specifically, the manipulation component 107 includes a manipulation handle 114 and a connecting rod 115. One end of the connecting rod 115 is connected to the connecting shaft 109, and the other end of the connecting rod 115 is connected to the manipulation handle 114. The manipulation handle 114, the connecting rod 115, the connecting shaft 109 and the material guiding plate 106 form a linkage structure connected in sequence. Swinging the manipulation handle 114 can drive the material guiding plate 106 to flip. The arc-shaped guide rail 113 includes a slider and an arc-shaped chute opened on the fixed plate 108. The connecting shaft 109 passes through the center of the arc-shaped chute, and the first positioning hole 110 or the second positioning hole 111 is opened at the bottom of the arc-shaped chute. The slider is slidably installed in the arc-shaped chute and is connected to the connecting rod 115 to realize the guiding of the movement of the connecting rod 115.
