The lower cutter body 43 movably penetrates through the lower strip-shaped hole 22 and corresponds to the upper cutter body 33.
[0021] On the top of one side of the opening of the box body 1, a socket 12 is opened. On the inner walls of the box body 1 on both sides of the socket 12, limit grooves 13 communicated with the socket 12 are respectively opened.

[0025] Working principle: First, pull out the plug board 5 from the socket 12. Then, according to the forage length required by the experiment, adjust the distances between adjacent upper knife bodies 33 and adjacent lower knife bodies 43 respectively. After adjusting the distances, insert the plug board 5 into the socket 12 and insert it downward along the limiting groove 13 into the slot 14. Then rotate the clamping plate 7 to open the baffle 6, and insert the experimental forage into the chopping chamber 2 from the feed port 11. Next, energize the upper electric telescopic rod 31 and the lower electric telescopic rod 41. The upper electric telescopic rod 31 drives the upper fixing plate 32 to move downward, and the lower electric telescopic rod 41 drives the lower fixing plate 42 to move upward, thereby driving the upper knife body 33 and the lower knife body 43 into the chopping chamber 2 to cut the forage. After cutting, both the upper electric telescopic rod 31 and the lower electric telescopic rod 41 contract, driving the upper knife body 33 and the lower knife body 43 to withdraw from the chopping chamber 2. Then, pull out the plug board 5 from the socket 12, collect the equal-length middle part for the silage experiment, ensuring that the length of the cut forage is unified, thereby avoiding experimental errors and improving the accuracy of the experimental results. Clean up the two shorter parts at both ends.
