Description

Hammer crusher

Technical Field

The utility model belongs to the technical field of mining machinery equipment, concretely relates to hammer brokenly machine.

Background

The hammer crusher is equipment for processing stone materials, and has the function of processing large-sized mined stone materials into small-size broken stones or sand materials. The present hammer crusher sold on the market generally comprises a machine case and a hammer head mechanism, wherein the machine case comprises an upper case body and a lower case body, and the hammer head mechanism is installed in the machine case. The existing hammer mechanism generally comprises a mandrel and a plurality of hammers axially arranged along the mandrel, and an integral structure is arranged between the hammers and a core disc on the mandrel. Because need regularly change after the tup wearing and tearing, consequently: replacing the ram means that the entire ram mechanism needs to be removed from the housing. Because the whole hammer head mechanism is very heavy, the hammer head mechanism is very difficult to operate when being taken out every time, and time and labor are wasted. In addition, the mandrel is generally not worn, which also results in a relatively high cost of use.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, 2 and 3, the hammer crusher comprises an upper box body 1 and a lower box body 2, and a hammer head mechanism is mounted on a box closing surface of the upper box body 1 and the lower box body 2. The hammer mechanism comprises a mandrel 7 and a hammer 5, wherein the mandrel 7 is rotatably supported at the box closing surface of the upper box body 1 and the lower box body 2, a group of core discs 7a are axially arranged on the mandrel 7, and the core discs 7a and the mandrel 7 are of an integral structure. A hammer head group is arranged between two adjacent core discs 7a, all hammer head groups are arranged side by side along the axial direction of the core shaft 7, and each hammer head group consists of a plurality of hammer heads 5 uniformly distributed along the circumferential direction of the core shaft 7. The periphery of the mandrel 7 is provided with a plurality of connecting shafts 6 side by side, the number of the connecting shafts 6 is consistent with that of the hammers 5 in each hammer group, each connecting shaft 6 simultaneously penetrates through the core disc 7a and the corresponding hammers 5 in all the hammer groups, and the connecting shafts 6 are tightly matched with the core disc 7a and the through holes in the hammers 5, so that the hammers 5 are detachably connected to the core disc 7 a. When a certain or some hammers 5 are abraded to reach a set abrasion loss, only the corresponding hammers 5 need to be replaced, and the original situation that the core disc and the core shaft need to be communicated to be replaced together is avoided, so that the overhaul is greatly facilitated, and the use cost is greatly reduced.

In order to further facilitate the replacement of the hammer 5, a connecting shaft through hole 1a is respectively formed in the front side wall and the rear side wall of the upper box body 1, the position of the connecting shaft through hole 1a is opposite to the uppermost connecting shaft 6, and the aperture of the connecting shaft through hole 1a is larger than the outer diameter of the connecting shaft 6. An inspection cover 4, a screw commonly used in a specific connection mode, is detachably connected to an outer orifice of each connecting shaft through hole 1 a. When the hammer head 5 is replaced, the connecting shaft 6 can be wholly or partially drawn out and penetrates through the connecting shaft through hole 1 a. After the connecting shaft 6 is pulled out, the hammerhead 5 to be replaced falls to the sieve plate 20 at the bottom of the lower box body 2. The bottom symmetry of lower box 2 front and back lateral wall is opened has an access hole, and the position of access hole corresponds the position of tup 5, and the outer orifice department of access hole is connected with an access door 8 with the mode of dismantling. The center of the upper end and the lower end of the access door 8 is correspondingly provided with a semicircular notch 81, and the flat-head bolt is clamped into the semicircular notch 81 and then is fixedly connected with the lower box body 2, so that the access door 8 is fixed on the lower box body 2. After the access door 8 is opened, the access hole is exposed so as to hook out the stuck stone at the sieve plate 20 or hook out the hammer 5 to be replaced by using an iron hook. When a new hammer head 5 is installed, the upper box body 1 needs to be opened, the hammer and the head mechanism are exposed, and after the brand-new hammer head 5 is replaced, the hammer head 5 is connected with the core disc 7a through the connecting shaft 6. The rest of the structure of the hammering machine in the scheme is completely the same as that of the prior art, and the detailed description is omitted.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
