Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and if not stated otherwise, the terms have no special meaning, and therefore, the scope of the present invention should not be construed as being limited.

If fig. 1 ~ 2, for prior art's sieve fixed establishment, sieve 10 sets up the below at rubbing crusher rotor 11, be fixed with fixed pressing plate flange 12 through bolt 13 on rubbing crusher's the base 14, fixed pressing plate flange 12 presses on sieve 10, sieve 10 below receives backup pad 8 to support like this, the top is pushed down by fixed pressing plate flange 12, it is spacing to realize, nevertheless need change sieve 10 with the whole dismantlement of both sides fixed pressing plate flange 12 when changing sieve 10, the process is loaded down with trivial details, unfavorable operation, need consume the plenty of time.

If fig. 3 ~ 8, for the utility model discloses a rubbing crusher sieve fixed establishment, be equipped with sieve 10 in the rubbing crusher cavity, the support piece that is used for supporting sieve 10 has in the rubbing crusher, support piece is the fixed backup pad 8 that sets up on wallboard 9, 8 shape in backup pad and the 10 bottom surface phase-matches of sieve, movable mounting has the installation component on rubbing crusher's wallboard 9, and be equipped with on wallboard 9 and have the fixed knot who is used for the fixed mounting subassembly position to construct, be equipped with on the installation component and be used for catching on or clip sieve 10 and come to carry out spacing limit structure to sieve 10. The position of the limit structure contacting the sieve plate 10 is positioned at the upper edge of the sieve plate 10.

The installation component comprises a rotary sleeve 4 rotatably connected to a wallboard 9, the fixing structure comprises a stud 5 fixed on the rotary sleeve 4, the stud 5 is perpendicular to the rotary sleeve 4, a through hole is formed in the wallboard 9, the stud 5 extends out of the through hole, and a first nut 7 is matched with the end part of the stud 5. In fact, the rotating sleeve 4 and the wall plate 9 can be fixedly connected by dismounting, such as clamping, and similar structures can be adopted as long as the rotation of the rotating sleeve 4 or the quick fixation and separation of the rotating sleeve 4 and the wall plate can be realized.

The telescopic is equipped with fixed rotating shaft 3 in the swivel sleeve 4, and the installation component still includes arm-tie 2, the first end and the 3 fixed connection of fixed rotating shaft of arm-tie 2, limit structure including fixed or integrative crotch 1 that sets up at 2 second ends of arm-tie, limit structure also can be the clamping jaw that sets up at 2 second ends of arm-tie, as long as can restrict the limit structure that sieve 10 prevented its drunkenness all can. The pulling force or clamping force of the hook 1 or the clamping jaw and the like to the sieve plate 10 can be along the oblique lower part, so that the pulling force or the clamping force and the supporting force of the supporting plate 8 to the sieve plate 10 form a mutual reaction force, the balance of the sieve plate 10 is ensured, and the sieve plate 10 cannot move.

And a second nut 6 is in threaded fit with one end of the fixed rotating shaft 3, which is far away from the hook 1, and the second nut 6 abuts against the end surface of the rotating sleeve 4.

The both ends of sieve 10 all are equipped with the installation component, and the installation component symmetry at every end sets up the left and right sides at sieve 10.

As figure 4, rely on first nut 7 to fix installation component and wallboard 9, change cover 4 and can rely on double-screw bolt 5 to carry out the circumferential rotation when first nut 7 is unscrewed, then fixed can not rotate when first nut 7 is screwed up, 6 groups of second nut are used for adjusting the axial position of changeing cover 4 on fixed pivot 3 for thereby adjust the flexible length of fixed pivot 3 and satisfy the position requirement of required fixed sieve 10.

According to the working principle, the hook 1 applies tension to the sieve plate 10, and one part of the tension is opposite to the direction of the supporting force of the supporting plate 8 to the sieve plate 10, so that the sieve plate 10 is fixed and prevented from moving. The upper end of the fixed rotating shaft 3 is subjected to the counter-pulling force of the sieve plate 10, and the lower end of the fixed rotating shaft 3 is subjected to the jacking force of the rotating sleeve 4 on the second nut 6 on the fixed rotating shaft 3, so that the tightening force of the hook 1 on the sieve plate 10 can be adjusted to a certain degree by adjusting the tightening force of the second nut 6.

As shown in fig. 5-6, when the screen plate 10 of the crusher needs to be fixed, the rotating sleeve 4 can be rotated by unscrewing the first nut 7, so that the whole installation assembly is driven to enable the hook 1 to be buckled on the screen plate 10, the bilateral symmetry ensures that the constraint force is sufficient, the first nut 7 is screwed to prevent the installation assembly from being constrained and loosened due to vibration, the screen plate 10 can be completely fixed through the self-locking structural design of the hook 1, when the axial position of the fixed rotating shaft 3 needs to be adjusted, the stretching of the fixed rotating shaft can be adjusted through the second nut 6, and the front and the rear groups ensure uniform bearing.

As shown in fig. 7-8, when the sieve plate needs to be disassembled and replaced, the second nut 6 is unscrewed, the hook 1 is separated from the sieve plate 10, the first nut 7 is unscrewed, the rotary sleeve 4 is rotated to enable the whole installation assembly to be far away from the sieve plate 10, the sieve plate 10 is replaced or disassembled, the purpose of quick disassembly and replacement can be achieved according to the steps, compared with the prior art, the inconvenience of the back-and-forth fixation and disassembly of the fixed pressing plate flange 12 and the base 14 is eliminated, the replacement time is shortened, the replacement efficiency is improved, and the benefit generated by the operation of the crusher can be integrally improved.

It should be understood that the above description of the specific embodiments is only for the purpose of explanation and not for the purpose of limitation. Obvious changes or variations caused by the spirit of the present invention are within the scope of the present invention.
