Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

As shown in fig. 1 and fig. 2, the embodiment of the utility model provides a pair of tooth roller crusher dodges and moves back mechanism, include disc spring sleeve pipe 1, give way fixed plate 4 and fluted roller bearing frame 13, disc spring sleeve pipe 1 and fluted roller bearing frame 13 fixed connection, be fixed with the backup pad 5 that gives way on the fixed plate 4 of giving way, it installs the ejector pin 7 that gives way on the backup pad 5 to give way, it is used for spacing bolt and nut 6 to be provided with on the ejector pin 7 to give way, be fixed with first disc spring cover 2 on the disc spring sleeve pipe 1, slidable mounting has second disc spring cover 3 on the first disc spring cover 2, first disc spring cover 2 with install disc spring 11 between the second disc spring cover 3.

In this embodiment, the belleville spring sleeve 1 is fixedly connected with the gear roll bearing seat 13 through the inner hexagonal stud 12, and the crusher gear roll 14 is installed on the gear roll bearing seat 13.

In this embodiment, the yielding fixing plate 4 is fixed on the frame.

In this embodiment, set up on the yielding fixed plate 4 and be used for fixing the draw-in groove of yielding backup pad 5, yielding backup pad 5 through hex bolts 8, flat ring 9 and spring ring 10 with yielding fixed plate 4 fixed connection.

In this embodiment, a plurality of threaded limiting holes are formed in the concession ejector rod 7 and are arranged along the length direction.

The working principle is as follows: in the device, a yielding fixed plate 4 is connected with a rack, and a belleville spring sleeve 1 is connected with a gear roller bearing seat 13; the yielding support plate 5 is arranged between the two clamping grooves of the yielding fixed plate 4, and the yielding ejector rod 7 is arranged in the middle of the yielding support plate 5 through threads and can move back and forth; during installation, the position of the yielding ejector rod 7 is adjusted, so that the butterfly spring 11 gives a conventional working pressure to the crusher tooth roller, and the normal crushing of materials by the tooth is ensured; when large-granularity uncrushable materials enter between the crusher toothed rollers 14, the distance between the two crusher toothed rollers 14 is widened by the materials, the crusher toothed rollers 14 drive the toothed roller bearing blocks 13 to move towards two sides, the toothed roller bearing blocks 13 compress the belleville springs 11, the pressure of the belleville springs 11 is increased, and after the uncrushable materials pass through, the pressure of the belleville springs 11 pushes the toothed roller bearing blocks 13 and the crusher toothed rollers 14 on the toothed roller bearing blocks 13 to return to normal working positions.

The technical effects are as follows: this tooth roller crusher dodges and moves back mechanism adopts mechanical type structure, and reaction time is short, dodges and moves back the back and resume fast, and the phenomenon that broken granularity enlarges reduces by a wide margin. This gear roller crusher dodges and moves back mechanism adopts the compression structure, simplifies the structure, and restart can resume production after taking place the limit protection, reduction downtime by a wide margin. The flash-back mechanism of the gear roller crusher adopts the belleville spring 11 as a pressure element, so that the acting force is large and the crushing efficiency is high.

The above disclosure is only for the specific embodiments of the present invention, however, the embodiments of the present invention are not limited thereto, and any changes that can be considered by those skilled in the art should fall into the protection scope of the present invention.
