A kind of automatic chaffcutter
The utility model relates to a kind of paper making raw material cutting equipment, relates in particular to a kind of automatic chaffcutter that is provided with special-purpose dust arrester.
Along with the development of paper-making industry, the scale of paper making equipment is increasing, and automaticity is also more and more higher.Now the full-automatic chaffcutter of huge power board that generally uses on the market especially with its automaticity height, need not the approval that advantage such as hand fed obtains users, but the dust arrester setting of this automatic chaffcutter is too simple, only be provided with one section sieve plate below tiltedly at the main shaft of hay cutter, blade is only through just discharging after the short time dedusting, dust removing effects is bad, still need to be equipped with separately cleaner in the following process process, increased the get the raw materials ready complexity of system of paper industry greatly.
Summary of the invention
At the problems referred to above, the utility model provides a kind of automatic chaffcutter that is provided with special-purpose dust arrester, can carry out effective dedusting in the chaffcutter process.
The technical scheme that the utility model adopted is as follows: a kind of automatic chaffcutter, comprise the hay cutter of feeding bin and feeding bin bottom, and described hay cutter below is provided with conveying worm, and the conveying worm below is provided with sieve plate, and the sieve plate outside is provided with dust gathering arrester.In this equipment, replace original belt conveyor to come convey materials with conveying worm, fall on the conveying worm through the material that hay cutter was handled, outwards fully stirring through spiral in the course of conveying, material and dust separation, dust falls into dust storage chamber between dust gathering arrester and the sieve plate through sieve plate, plays the effect of dedusting thus.
Further, the main shaft axially parallel of described conveying worm and hay cutter is convenient to carry at any time the forage after the cutting.
Further, the whole sieve plate of described dust gathering arrester shade which is provided with and takes out the dirt pipe, sieve plate is covered by whole, and dust enters dust gathering arrester by sieve plate, treats that the space collection in the dust gathering arrester is completely extracted dust out from taking out the dirt pipe back, and can effectively prevent dust from flying by taking out the negative pressure that forms in the dirt pipe aspiration procedure.
Further, described sieve plate is an arc screening plate, can effectively avoid slow-witted material problem, and the assurance material is fully discharged.
The utility model improves by the shape to original sieve plate, and replaces belt conveyor with conveying worm, can carry out effective dedusting in the chaffcutter process, and can suppress dust from flying, has improved working environment greatly.

Fig. 3 is that the A-A of Fig. 2 is to view;
Among the figure, 1, main shaft, 2, sieve plate, 3, conveying worm, 4, take out the dirt pipe, 5, dust gathering arrester, 6, dust storage chamber, 7, feeding bin.
The specific embodiment
A kind of automatic chaffcutter, the hay cutter that comprises cylindrical shape feeding bin 7 and feeding bin 7 bottoms, described hay cutter below is provided with the conveying worm 3 with its main shaft 1 axially parallel, conveying worm 3 belows are covered with sieve plate 2, sieve plate 2 adopts arc screening plate, and sieve plate 2 outsides are covered with dust gathering arrester 5, and described dust gathering arrester 5 is provided with takes out dirt pipe 4, the confined space that dust gathering arrester 5 and sieve plate are 2 is used for collecting dust as dust storage chamber 6.
