Although the assembled low-speed pulverizer cavity can effectively avoid the accumulation phenomenon of materials, the assembled low-speed pulverizer cavity is more complex in structure and more difficult to assemble and disassemble, and the cutter groove transition bracket arranged needs to form a smooth transition arc surface with the arc groove, so that the cutter groove transition bracket and the arc groove are higher in processing requirement, and the production cost of the whole cavity is also increased.
The utility model discloses to the problem that exists among the prior art, provide better scheme, need not dig out the pit between the circular arc recess, also need not set up sword groove transition bracket between the circular arc recess, but directly let direct contact between two circular arc recesses to the contact position to two circular arc recesses carries out appropriate chamfer and handles, thereby can enough avoid the sword chamber mounting panel to touch the cutter at the upset in-process, can also be very big avoid the material to hide and receive in circular arc recess butt joint department.
The cavity of the assembled low-speed pulverizer provided by the invention is further described in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the claims and the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
The embodiment provides a cavity of an assembled low-speed pulverizer, as shown in fig. 2 and 3, fig. 2 is a schematic side structure view of the cavity when a knife cavity mounting plate provided by the embodiment is folded; fig. 3 is a schematic side view of the knife cavity mounting plate provided in this embodiment when the knife cavity mounting plate is opened.
The cavity of the assembled low-speed pulverizer provided by the embodiment is mainly formed by enclosing two side plates 5 fixed on a base 6, and a left knife cavity mounting plate 10 and a right knife cavity mounting plate 10 which are oppositely arranged. Wherein, the knife cavity mounting plate 10 is movably connected on the side plate 5, for example, the knife cavity mounting plate 10 is hinged on the side plate 5, when the knife cavity mounting plate 10 is closed or opened, the knife cavity mounting plate 10 can rotate around the hinged position. In order to accommodate the rotary cutter 7 in the pulverizer, the two cutter cavity mounting plates 10 are provided with arc grooves 3, and when the cavity is closed, the arc grooves 3 on the two cutter cavity mounting plates 10 are contacted with each other to form an arc shape. Obviously, the space formed by the two arc grooves 3 after being folded is a complete cutter groove with smooth arcs; and, on the sword chamber mounting panel 10, be located two the circular arc recess 3 contact department is equipped with chamfer 31, the size of chamfer 31 can be according to the particle size of crushing material, the size of cutter 7, actual user demand etc. set up, its purpose in order to prevent the sword chamber mounting panel 10 from touchhing the cutter 7 in the upset process.
Can also know through the explanation of background art, pin-connected panel low-speed rubbing crusher cavity among the prior art still has to produce easily between sword chamber mounting panel and the curb plate and rock, causes the clearance grow, aggravates the wearing and tearing of sword chamber mounting panel. Those skilled in the art will readily understand that a certain gap is required to be maintained between the knife cavity mounting plate and the side plate, and the size of the gap can be set according to actual needs, for example, the size of the gap is set to 0.3 mm. Therefore, as a possible solution, the cavity may further include a gap adjusting device for adjusting a gap between the knife cavity mounting plate 10 and the side plate 5.
In the actual use process, the cutter cavity mounting plate 10 and the side plate 5 inevitably shake, so that the size of the gap between the cutter cavity mounting plate 10 and the side plate 5 is changed. In order to avoid a large variation in the gap between the knife compartment mounting plate 10 and the side plate 5, as shown in fig. 4 and 5, the gap adjusting means may include a set screw 81 and a thrust bearing 82; moreover, the thrust bearing 82 is sleeved on the hinge shaft 9 between the side plate 5 and the knife cavity mounting plate 10; one end face of the thrust washer at one end of the thrust bearing 82 is in contact with one end face of the knife cavity mounting plate 10 close to the side plate 5, the set screw 81 is screwed in the side plate 5, and the tail end of the set screw 81 abuts against the end face of the thrust washer at the other end of the thrust bearing 82. In this arrangement, the set screw 81 can exert a certain pressure on the thrust bearing 82 through its own thread locking capability, and the thrust bearing 82 is in contact with the knife cavity mounting plate 10, so that the knife cavity mounting plate 10 can be firmly and reliably limited. Of course, since there are usually two side plates 5, the knife chamber mounting plate 10 is located between the two side plates 5 and is hinged to the two side plates 5. That is to say, the thrust bearing 82 between the side plate 5 and the knife cavity mounting plate 10 can press the knife cavity mounting plate 10 at two ends, so that the gap between the knife cavity mounting plate 10 and the side plate 5 can be greatly reduced.
Then, as a realizable solution, the side plate 5 is further provided with a stepped hole 84 for installing the thrust bearing 82, the axis of the stepped hole coincides with the axis of the hinge shaft 9, and the depth of the stepped hole is greater than the axial length of the thrust bearing; and a screw hole 83 for screwing the set screw 81 penetrates the side plate 5 and communicates with the stepped hole 84. Due to the step hole 84 capable of accommodating the thrust bearing, the gap between the knife cavity mounting plate 10 and the side plate 5 is not enlarged due to the thrust bearing, and the gap between the two can be adjusted according to the screwing depth of the set screw 81, so as to meet the actual use requirement. In order to facilitate screwing of the tightening thread 81, the axial direction of the threaded hole 83 is parallel to the axial direction of the hinge shaft 9.
In addition, because the contact area between the set screws 81 and the thrust bearings 82 is small, at least two sets of set screws 81 can be arranged and uniformly distributed on the side surface of the hinge shaft 9, so that the thrust bearings 82 are stressed in a balanced manner.
When the cavity is opened, the knife cavity mounting plate 10 can turn around the hinge shaft 9, and at the moment, friction is generated between the knife cavity mounting plate 10 and the thrust bearing 82 which is in contact with the knife cavity mounting plate, so that the gap between the knife cavity mounting plate 10 and the side plate 5 is inevitably influenced in the past. Therefore, the thrust bearing 82 can rotate, so that a gap exists between the inner side surface of the thrust washer contacting the knife chamber mounting plate 10 and the hinge shaft 9, and a gap exists between the outer side surface of the thrust washer and the side plate 5. Since the thrust bearing 82 is pressed, the retainer ring contacting the knife chamber mounting plate 10 does not separate and can rotate along with the knife chamber mounting plate 10.
As will be readily understood by those skilled in the art, the set screw 81 is susceptible to loosening under constant vibration over time, thereby reducing the restraining effect on the thrust bearing 82, resulting in a large degree of variation in the gap between the knife chamber mounting plate 10 and the side plate 5. In order to enable the set screw 81 to continuously provide an effective limiting effect for the thrust bearing 82, the present embodiment further provides a refinement: the gap adjusting means further comprises a locking screw 85 for locking the set screw 81. In order to reduce the occupied space, the length of the locking screw 85 may be made smaller than the length of the set screw 81. Of course, it is described that the set screw 81 is screwed into the threaded hole 83, so that the length of the set screw 81 is smaller than the thickness of the side plate 5, and the locking screw 85 is directly screwed into the threaded hole 83, so that the tail end of the locking screw 85 abuts against the head end of the set screw 81, thereby achieving the locking effect of the set screw 81.
In addition, in order to ensure that the locking screw 85 is not loosened any more, the head end of the locking screw 85 may be protruded out of the surface of the side plate 5; the gap adjusting means may further include a cover plate 86, and the cover plate 86 is fixed to the side plate 5 and is in contact with the locking screw 85. The height of the locking screw 85 projecting above the side plate needs to be at least 0.2mm to ensure effective contact with the cover plate 86.
In summary, the cutter groove transition bracket in the prior art is eliminated in the cavity of the assembled low-speed grinder, so that the structural complexity is reduced; and a chamfer is also arranged to prevent the cutter cavity mounting plate from touching the cutter during overturning. The utility model provides a pair of pin-connected panel low-speed rubbing crusher cavity has the clearance adjustment function, and clearance between sword chamber mounting panel and the curb plate not only can be adjusted to clearance adjusting device through setting up, can also inject the home range of sword chamber mounting panel for clearance between sword chamber mounting panel and the curb plate keeps invariable.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
