Detailed Description
Other objects and advantages of the present invention will become apparent from the following explanation of the preferred embodiments of the present application.
The machine body of the green feed harvester consists of a travelling device, a header, a feeding device, a chopping device and a throwing device. The green fodder harvester advances through advancing device, and the green fodder crop is reaped through the header in the process of advancing, then conveys the green fodder crop that reaps to the comminution device by the feeding device behind the header and cuts up, then throws the discharge of the shredded green fodder crop through throwing the device.
The chopper mechanism typically employs rotating chopper knives in combination with stationary knives 3 for chopping. The chopping hob is provided with a plurality of movable cutters 2, after the chopping hob rotates, the movable cutters 2 are sequentially matched with the fixed cutters 3 to chop the green feed crops, and the scraps are thrown to the throwing device.
The fixed cutter adjustable mechanism is used for adjusting the distance between the fixed cutter 3 and the movable cutter 2, so that the abrasion loss of the movable cutter 2 is compensated by adjusting the position of the fixed cutter 3 under the condition that the movable cutter 2 is not adjusted, and the normal work of the chopping device is ensured.
The adjustable mechanism of the fixed cutter of the green fodder harvester comprises a supporting piece 4 and an adjusting shaft 6, wherein the supporting piece 4 is used for supporting the fixed cutter 3, and the adjusting shaft 6 is used for adjusting and keeping the distance between the fixed cutter 3 and the movable cutter 2.
The supporting member 4 is pivotally connected to the frame 1 via a supporting shaft 5, and the supporting member 4 includes a first end and a second end that are opposite to each other. The first end of support piece 4 is fixed with stationary knife 3, adjusting shaft 6 with greenfeed harvester's frame 1 rotatable coupling, adjusting shaft 6 with support piece 4 threaded connection. When the adjusting shaft 6 is rotated, the threaded part of the adjusting shaft 6 pushes or pulls the second end of the supporting piece 4 to deflect, so that the distance between the fixed knife 3 and the movable knife 2 is adjusted through the lever principle.
The distance a between the second end of the support member 4 and the support shaft 5 is greater than the distance B between the first end of the support shaft 5 and the support shaft 5, and the ratio between the distances may be, for example, a: and B is 10: 1. Therefore, when the offset distance of the second end of the supporting piece 4 is 10mm, the offset distance of the first end is 1mm, and the distance between the fixed knife 3 and the movable knife 2 is conveniently and accurately controlled.
The hand wheel 12 is connected with the adjusting shaft 6, and the adjusting shaft 6 can be rotated quickly and conveniently by rotating the hand wheel 12. Further, a dial scale can be included, and the offset distance of the fixed knife 3 can be read conveniently through the dial scale.
The adjusting shaft 6 is connected to the frame 1 via a support bearing, preferably a self-aligning bearing, which is able to accommodate the deflection of the adjusting shaft 6 during the adjustment of the support 4.
The fixed cutter 3 and the supporting piece 4 are fixedly connected through screws, so that the fixed cutter 3 is convenient to disassemble and assemble.
The support member 4 is plate-shaped and can reliably support the stationary blade 3. The width of the first end of the supporting member 4 in the up-down direction is wider than the width of the second end of the supporting member 4 in the up-down direction.
The utility model also provides a green feed harvester which comprises the fixed cutter adjustable mechanism of the green feed harvester.
The green feed harvester also comprises a knife sharpening disk 7, and the knife sharpening disk 7 is used for sharpening the knife after the moving knife 2 is abraded.

A ratchet mechanism is also arranged between the screw rod and the frame 1 and is used for preventing the grinding cutter disk 7 from retreating when grinding a knife.
In the prior art, the moving blade 2 is usually driven to rotate by the power of a traveling device, generally, the traveling device drives the moving blade 2 to rotate in the forward direction, that is, the rotating direction is the same as the rotating direction during working, and the blade of the moving blade 2 is sharpened forward. This type of sharpening is very dangerous and can easily damage the sharpening disk 7 and cause casualties by the possible flying of fragments.
In order to solve the technical problems, the utility model provides a reverse sharpening mechanism which can switch the rotating direction of a moving knife to sharpen the knife reversely, namely, when the knife edge is at the back, the rotating speed of an output shaft of a travelling device can be reduced, so that the rotating speed of a moving knife 2 is suitable for sharpening the knife.
Specifically, as shown in fig. 2, the green fodder harvester includes a first input shaft 8, and the first output shaft 8 is connected with the movable knife 2 and used for driving the movable knife to rotate during normal operation.
