Abstract

Disclosed is a hammer type breaker box body structure capable of opening box covers. A closed box body of an integral breaker is divided into an upper box body and a lower box body by a central horizontal line of a hammer core shaft, and the upper box body is divided into a left upper box body and a right upper box body by a central vertical line of the hammer core shaft. The lower box body is steady. The left upper box body and the right upper box body can be independently opened from left and right through independent hydraulic support systems. Inside of the closed box body can be completely exposed, observation for working clearance and wearing conditions of wearing parts is convenient and easy, and also replacement operation of wearing consumables as hammer head guard boards and the like is convenient and easy.

Description

A kind of hammer mill body structure of opening case lid

Affiliated technical field:

The utility model relates to a kind of body structure of hammer mill.

Background technology:

Hammer mill is a kind of disintegrating apparatus efficiently, and its crushing efficiency and the broken fineness that reaches are difficult to reach for other disintegrating apparatus.In recent years, along with mine industry generally adopts " the how broken mill that lacks " technology and the preceding preliminary election technology of mill, the fineness requirement before ore is gone into to grind is more and more higher, and the scope of application is also more and more wider.Hammer mill conduct equipment in small, broken bits efficiently also is subjected to paying close attention to widely and paying attention in recent years.Very big progress has been arranged at aspects such as hammer head material, structures.The material consumption of the bigger prolongation service time of tup, ton ore reduction also reduces significantly.But because the suitable gap that the efficient operation principle of hammer mill requires tup and backplate will have certain limit, and tup and backplate itself are expendable parts, along with the continuity of service time, the working clearance is increasing, to a certain degree tup and backplate all must be changed.In the past because the outer case of hammer mill is a closed box, the attrition situation of working clearance that it is inner and tup backplate etc. can't be observed, changing tup, backplate etc. also must be with the casing completely knocked down, and workload is big, the activity duration is long, has brought very big inconvenience for actual the use.Though the effect in small, broken bits of hammer mill generally acknowledges that all operation, the inconvenience of safeguarding are considered to a big fatal drawback of hammer mill, with this resistance that is subjected to a lot of users, cause at metal mine seldom by wide-scale adoption.

Summary of the invention:

For the hammer mill with high effect in small, broken bits can be widely applied by reality, the utility model provides a kind of hammer mill body structure that can arbitrarily open case lid.This can open the feasible very convenient easy row that become such as working clearance, replacing tup backplate of observing of hammer mill of case lid.

The technical scheme that its technical problem that solves the utility model adopts is: is that the boundary is divided into lower box two parts with whole hammer crushing box body with hammer mandrel horizontal center line.Lower box maintains static on the ground pedestal as a whole.Upper box is that the boundary is further divided into left and right upper box two parts with the vertical center line of hammer mandrel then.The hinge that these two ends, left and right upper box above respectively lower box line of demarcation are provided with is the center, can independently under the hydraulic system effect respectively arbitrarily open to both sides, and the hammer mill inside behind the unlatching upper box will appear fully.

The beneficial effects of the utility model are: be divided into upper and lower casing by the closed box with whole hammer mill, the split mode that again upper box is divided into left and right upper box, by left and right independently hydraulic system is set, left and right upper box can arbitrarily be opened independently, the closed interior of hammer mill is appeared fully, make and observe the working clearance, observe tup backplate abrasion condition, and change rapid wear expendable parts such as tup, the backplate very convenient easy row that becomes.Make hammer mill become one and operate and safeguard disintegrating apparatus very easily.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front elevation of opening the hammer crushing box body of case lid of the present utility model.

Fig. 2 is the front elevation after the upper left casing of first embodiment of the present utility model is opened.

Among the figure, 1. hammer mill lower box, 2. hammer mill upper box, 3. hammer mill feed hopper, 4. hydraulic actuating mechanism, 5. hinge, 6. lower box supports hinge, and 7. upper box supports hinge.

The specific embodiment:

Present embodiment is that whole hammer crushing box body is divided into a fixing lower box 1 and two upper boxes that can open respectively 2.

Upper box 2 supports hinge 7 with hydraulic actuating mechanism 4 by upper box and connects.Lower box 1 supports hinge 6 with hydraulic actuating mechanism 4 by lower box and connects.

Each left side or upper right casing 2 are provided with hydraulic actuating mechanism 4.

The hydraulic actuating mechanism 4 of left and upper right casing 2 can make a left side or upper right casing 2 open operation.

Upper box 2 connects by hinge 5 with lower box 1.Hinge 5 is arranged at edge, lower box line of demarcation.

When the hydraulic actuating mechanism 4 on each upper box 2 both sides opens or close up operation, support the connection effect of hinge 7 by upper box, make corresponding upper box 2 foldings operation.Because upper box 2 and lower box 1 linked by hinge 5 simultaneously, upper box 2 propped up by hydraulic actuating mechanism 4 or the time spent is done in drawing, will be center rotation folding with hinge 5, the random unlatching of realization upper box 2 or close up.

Claims

1. the hammer mill body structure that can open case lid is characterized in that: be provided with hinge and hydraulic actuating mechanism between two upper boxes of hammer mill and a lower box.

2. a kind of hammer mill body structure of opening case lid according to claim 1, it is characterized in that: is that the boundary is divided into two parts of lower box with whole hammer crushing box body with hammer mandrel horizontal center line, and upper box is that the boundary is further divided into left and right upper box two parts with the vertical center line of hammer mandrel again.

3. a kind of hammer mill body structure of opening case lid according to claim 1 is characterized in that: about the hinge that can two ends, above respectively lower box line of demarcation be provided with of two upper boxes be that unlatching is rotated at the center independently.

4. a kind of hammer mill body structure of opening case lid according to claim 1 is characterized in that: each left side or upper right casing are implemented to open by hydraulic actuating mechanism.

5. a kind of hammer mill body structure of opening case lid according to claim 1 is characterized in that: open the hydraulic actuating mechanism of upper box, its upper end is linked in the upper box supporting hinges, and the lower end is linked in the lower box supporting hinges; The lower box supporting hinges maintains static with lower box, and the upper box supporting hinges moves with upper box.
