[0035] The sealing box 5 is connected to the support frame 2 through a connecting frame 18, which makes it convenient for the equipment to disassemble the sealing box 5 when passing through a narrow space, and then reassemble it in sequence. The collection box 17 is positioned by installing a lock buckle, and the collection box 17 mainly plays the role of recovering straw fragments.

[0036] Working principle of this utility model:

[0037] By setting up a dust removal mechanism, the discharge pipe 4 is connected to the sealing box 5 and is in a connected state. The sealing box 5 is in a sealed state when it slides to the tail end through the collecting box 17. At this time, the discharge barrel 3 passes the crushed straw into the sealing box 5 through the discharge barrel 3 and the discharge pipe 4. The straw fragments fall into the collecting box 17, and the dust with smaller texture is driven by the exhaust fan 7 to be discharged outward. The exhaust speed of the exhaust fan 7 is in a low speed state to avoid the straw fragments being discharged due to excessive wind speed. The exhaust port of the exhaust fan 7 is respectively provided with a coarse dust prevention The net 14 and the high-efficiency dust-proof net 15 filter the dust and provide protection for the processing environment. The movable block 10 installed on the side of the positioning frame 11 is rotatably connected to the movable seat 9. When it is necessary to clean the dust on the surface of the coarse-effect dust-proof net 14 and the high-efficiency dust-proof net 15 in the later stage, the bolts at the fixed seat 13 can be removed first, and then the two sets of positioning frames 11 are moved downward by a certain angle in turn, and the coarse-effect dust-proof net 14 and the high-efficiency dust-proof net 15 can be pulled out for cleaning.
