Pressing mechanism 4 operation principles: utilize pressure regulation bar 32 to rotate up or down and reference pressure sensors value of feedback setting precompression, by the dull and stereotyped 35 pairs of disk springs pressurization of pressure regulation, thereby pass to floating weight 45 through connecting rod 32, realize banburying chamber's cavity is applied precompression.Specifically be in mixer mixing process, requirement adds 5 pairs of banburying chamber's precharge pressures of binder mechanism, its method is: pressure regulation bar 32 is down rotated, push down disk spring 34 by pressure regulation flat board 35, connecting rod 36 is produced a downforce, pressure sensor is equipped with at dull and stereotyped 35 places in pressure regulation, can measure pressure regulation pressure.If reduce pressure, pressure regulation bar 32 up can be rotated, like this, just can add different precompressions by rotation pressure regulation bar 32; In the material mixing process, sizing material can upwards produce one and impact the power of floating, and drives floating weight 45 and moves upward, and disk spring 34 produces micro-strain and plays the shock absorbing effect.

Retaining mechanism 5 operation principles: when requiring to lock upper and lower banburying chamber, only need be with upper and

lower banburying chamber

2,3 closures, then, with clamping

screw

21,25 in bearing pin 18 rotates in the banburying chamber 3 opening that is provided with, with the banburying chamber upright position,

screw nut

46,47 respectively and just can lock upper and lower banburying chamber; When require opening upper and lower banburying chamber, then only the

nut

46,47 that clamping

screw

21,25 connects need be unscrewed, and

bolt

21,25 is rotated to down banburying chamber 2 belows, just can open upper and lower banburying chamber.

Exchanging rotor more fast: shown in figure four, open banburying chamber 3 on the banbury, open and open the left and right side plate in banburying chamber both sides, left shaft holder loam cake, right bearing seat loam cake promptly can take out a pair of

rotor

14,15 from bearing block, change an other group rotor.

Both can freedom rotate upper and lower banburying chamber of the

present utility model

2,3 up and down separately, in the material mixing process, only need retaining mechanism locking or unclamp, and can open fast and closed upper and lower banburying chamber, and are simple in structure, easy to operate.
