Specifically, the upper end surface of the scale body 531 is provided with scales, and a chute 535 is arranged in the scale body 531; the locking block 532 includes a body 536 having a cross shape as a whole, and the shape of the chute 535 is matched with the body 536; the upper end surface of the body 536 is provided with a shifting head 537, and the shifting head 537 extends out of the upper end surface of the scale body 531 from the chute 535 so as to conveniently move the locking block 532 through the shifting head 537, and the shifting head 537 corresponds to the scale, so as to quantitatively adjust the moving distance of the locking block 532.
The lower end surface of the body 536 is provided with a baffle 538, and the baffle 538 extends from the chute 535 to the lower end surface of the scale body 531 and extends to the side surface of the sliding seat 521; accordingly, both sides of the slide base 521 are provided with both side bending portions 528, so that when the roll gap is adjusted, the slide base 521 presses the stopper 538 through the both side bending portions 528 to stop the adjustment.
The upper end surface of the scale body 531 is further provided with four threaded through holes 539, the positions of the four threaded through holes 539 are respectively matched with the movable ranges of the four locking blocks 532, and locking bolts 5310 are arranged in the threaded through holes 539, so that when the locking blocks 532 move to the target positions, the locking bolts 5310 are screwed to prop against the body 536, and the locking blocks 532 cannot move.
In this embodiment, the scale includes a first scale 5311 and a second scale 5312, the first scale 5311 is in millimeter units, the second scale 5312 is configured with fifty divisions, and by matching the first scale 5311 and the second scale 5312, the configuration of the moving distance of the locking piece 532 can be accurate to 0.02mm, and the moving precision of the locking piece 532 is further improved.
It will be appreciated that when the roll gap is adjusted, the locking block 532 is slid a predetermined distance and is stopped at a predetermined scale. Then, the double threaded screw 511 is rotated to bring the sliding bases 521 toward or away from each other, and when the sliding bases 521 are pressed against the locking blocks 532, the rotation of the double threaded screw 511 is stopped, so that the sliding bases 521 are stopped at the predetermined positions.
On the one hand, when the operator feels that the double-threaded screw 511 is not screwed, the slide base 521 is pressed to the locking piece 532, and it is considered that the slide base 521 is moved to a proper position, that is, by artificially feeling the degree of pressing, if the pressing is not in place or excessive, accuracy of the moving distance of the slide base 521 is affected.
On the other hand, in a considerable number of cases, it is impossible to dispense a pair of slide bases 521 to move by the same distance, so that after the slide bases 521 having a relatively small moving distance are moved in place, the slide bases 521 having a relatively large moving distance still need to continue to move, but since the slide bases 521 having a relatively small distance are caught by the catching blocks 532, the slide bases 521 having a relatively large moving distance cannot continue to move.
In order to eliminate the above-mentioned problems, in the ore crushing device with an adjustable roll gap according to the present embodiment, the first nut block 512 and the second nut block 513 are in contact with the vertical bending portion 522, and in one state, the first nut block 512 and the second nut block 513 are fixed to the vertical bending portion 522; in the other state, the first nut block 512 and the second nut block 513 are moved relative to the vertical bent portion 522.
Thus, in a state that the sliding seat 521 is not pressed against the locking piece 532, the first nut block 512 or the second nut block 513 can drive the sliding seat 521 to move; in the other state, that is, when the slide base 521 has been pressed against the locking piece 532, the first nut piece 512 or the second nut piece 513 cannot move the slide base 521.
With the above arrangement, after the sliding seat 521 is pressed to the locking block 532 and moved in place, the first nut block 512 or the second nut block 513 cannot drive the sliding seat 521 to move, although the first nut block 512 or the second nut block 513 continues to move, the position of the sliding seat 521 is not changed any more, so as to realize the automatic stop adjustment function of the roll gap adjustment unit 500. Thus, the error caused by the artificial sensing of the extrusion degree is eliminated, and the problem that the pair of sliding seats 521 are in place in a differential speed is solved.
Specifically, the upper ends of the first nut block 512 and the second nut block 513 are provided with a mounting groove 518, a sliding plate 519 capable of sliding up and down is arranged in the mounting groove 518, a force applying tooth 5110 is fixedly arranged at the upper end of the sliding plate 519, a spring 5111 is also arranged in the mounting groove 518, and the upper end and the lower end of the spring 5111 are respectively fixedly connected with the lower end face of the sliding plate 519 and the bottom face of the mounting groove 518; the bottom of the vertical bending part 522 is provided with more force receiving grooves 529 than the force application teeth 5110, and the shape and the size of the force receiving grooves 529 are matched with those of the force application teeth 5110.
Thus, when the slide seat 521 is not pressed against the locking piece 532, the urging teeth 5110 are kept in the extended state by the spring 5111, and the first nut block 512 or the second nut block 513 can move the slide seat 521. When the sliding seat 521 has been pressed against the locking piece 532, the force-applying tooth 5110 continuously retracts into the mounting groove 518 against the elastic force of the spring 5111 under the pressing action of the force-receiving groove 529, and the first nut block 512 or the second nut block 513 cannot drive the sliding seat 521 to move from one force-receiving groove 529 to the next adjacent force-receiving groove 529.
Through the arrangement, the sliding seat 521 automatically stops after moving in place, so that errors caused by manual sensing of the extrusion degree are eliminated, and the problem that a pair of sliding seats 521 are differentiated in place is solved.
Preferably, the slide plate 519 and the force application teeth 5110 are integrally formed.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
