Hammer mill charging scraping anti-clogging mechanism
Technical field
The utility model is mainly concerned with the mineral processing equipment field, refers in particular to a kind of hammer mill.
Background technology
Hammer mill often is used to the mineral processing of various fragile materials.Traditional hammer mill comprises motor, main shaft, hammer, crusher chamber and hopper, is used for the hammer of break mined material to be arranged in crusher chamber and to be fixed on the main shaft, and under the drive of motor, the main shaft band hammer rotation at a high speed in crusher chamber.Material feeds in the crusher chamber from the material inlet of top hopper, is subjected to the strike, impact, shearing, abrasive action of high-speed motion hammer and pulverizes.Bottom in crusher chamber is provided with sieve plate, and the grade less than screen size in the comminuting matter is discharged by sieve plate, continues to be subjected to the strike and the grinding of hammer greater than the coarse fraction detention of screen size on sieve plate, at last by outside the sieve plate discharge machine.In the tradition hammer mill, after material enters into crusher chamber from feed hopper, can under the hammer effect of rotation at a high speed, be thrown to and carry out crushing operation on the crusher chamber inwall; When big or viscosity is strong when the humidity of materials that is broken, tend under the drive of hammer, high speed impact is thrown on the flat board of hopper end opening rear side, and bonding is got up, because broken away from the strike scope of hammer, adhesive can't broken be removed, and the time one constantly piles up for a long time, even stops up the feed opening of feed hopper and can't normally use.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, easy to operate, hammer mill charging scraping anti-clogging mechanism that can guarantee the complete machine running stability.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of hammer mill charging scraping anti-clogging mechanism, comprise the charging baffle plate that is positioned at disintegrating machine hopper feed opening place, it is characterized in that: the bottom of described charging baffle plate is connected with and is used for the anti-blocking scraper plate that cooperates with crusher chamber in the disintegrating machine, and described charging baffle plate links to each other with the control stick that is positioned at the crusher chamber outside by linkage.
As further improvement of the utility model:
Described anti-blocking scraper plate is and the isodiametric arc of crusher chamber.
The length of described arc is 1/4th of crusher chamber outer circumference.
Compared with prior art, advantage of the present utility model is:
1, the utility model hammer mill charging scraping anti-clogging mechanism, simple and compact for structure, with low cost, can guarantee the complete machine traveling comfort.
2, when charging baffle plate and anti-blocking scraper plate are descended, the feed opening of disintegrating machine hopper is closed, drop to the excircle place of crusher chamber simultaneously as the arc of anti-blocking scraper plate, utilize the scraping of hammer on anti-blocking scraper plate inwall of rotation at a high speed, the material that is bonded on the anti-blocking scraper plate is removed, to reach anticlogging purpose.
3, the operation principle of disintegrating machine requirement hammer must be just can open the feed opening blanking under the situation of rotation.Therefore in the blanking process, anti-blocking scraper plate breaks away from broken circular arc chamber, has partial material to be thrown out of during this period of time, and is bonded on the feed opening rear plate.Therefore, when closing the charging baffle plate, the material that can utilize the lower limb of anti-blocking scraper plate will be bonded on the rear plate scrapes off, and removes totally, avoids the charging baffle plate to be stuck.

The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model is mainly used in the hammer mill, this hammer mill comprises disintegrating machine hopper 2, active motor (not shown), main shaft 10, hammer 9 and the crusher chamber of being made up of last crusher chamber 4 and following crusher chamber 5, and disintegrating machine hopper 2 is provided with hopper cover 1; Under the driving of active motor, drive hammer 9 high-speed motions on the main shaft 10, the material that is entered crusher chamber by disintegrating machine hopper 2 is carried out fragmentation processing.The utility model hammer mill charging scraping anti-clogging mechanism, comprise the charging baffle plate 3 that is positioned at disintegrating machine hopper 2 feed opening places, the bottom of charging baffle plate 3 is connected with and is used for the anti-blocking scraper plate 8 that cooperates with crusher chamber in the disintegrating machine, and charging baffle plate 3 links to each other with the control stick 6 that is positioned at the crusher chamber outside by linkage 7.By control stick 6 can drivening rod mechanism 7 and charging baffle plate 3 carry out upper and lower motion.In the present embodiment, anti-blocking scraper plate 8 is and the isodiametric arc of crusher chamber that the length of arc is 1/4th of crusher chamber outer circumference.When charging baffle plate 3 and anti-blocking scraper plate 8 were risen, the discharging opening of disintegrating machine hopper 2 was opened, and material enters into crusher chamber; When charging baffle plate 3 and anti-blocking scraper plate 8 were descended, the discharging opening of disintegrating machine hopper 2 was closed.When anti-blocking scraper plate 8 descended, its lower limb can be removed the material that adheres on the rear plate clean; And drop to the anti-blocking scraper plate 8 of arc at the excircle place of crusher chamber, and then utilize the scraping of hammer 9 on anti-blocking scraper plate 8 inwalls of rotation at a high speed, the material that sticks on the anti-blocking scraper plate 8 is removed, to reach anticlogging purpose.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
