Abstract

The utility model relates to a piecewise embedded type grid bar body for an impact-type hammer crusher, and is composed of a grid bar formed by the linking of a group of supporting plates fixed in a row. The whole grid bar is piecewise assembled. One end rabbet of each section of the grid bar is embedded in the trapezoidal hole of an outer side supporting plate. The other end rabbet is embedded in the trapezoidal groove of an inner side supporting plate. The point adjacent to the rabbets of the two sections of the grid bars is pressed tightly by a T-shaped pressing block in a straight line to prevent the grid bars from moving and jumping and to protect the supporting plates. The utility model has the advantages of reasonable whole structure, the easy changing of the grid bars, the high utilizing rate of the supporting plates and lower whole cost, and is suitable for the requirement of small batch production.

Description

Sectional inlaying type comb bars of beater type crushing machine

The utility model relates to mine disintegrating machine equipment; Be particularly related to the improvement of beater type disintegrating machine grid section body structure.

According to German O﹠K(Orenstein ﹠ Koppel) company " MAMMUT CRUSHER " magazine record, the disintegrating machine grid section body through type structure (accompanying drawing 1) that the said firm makes penetrates support plate in groups to whole grid section.Grid section adopts anti-wear performance rolled parts preferably, and its form accuracy, dimensional accuracy, rigidity requirement are all higher, and expense is high takes, suitable mass production scale.Because the support plate marginal portion directly contacts with material, also to adopt the good material of wearability in addition.In case and grid section and support plate are cumbersome when partly changing.

The purpose of this utility model: in order to avoid the wearing and tearing of support plate as far as possible, can after grid section wearing and tearing in various degree, can transposition exchange even change again simultaneously, adopt segmentation mosaic structure, make whole grid section body under the identical prerequisite of function, reduce cost.

Design of the present utility model: support plate is fixed grid section in a row in groups, and every grid section is divided into several sections by whole.Every section grid section one end tenon embeds in the hole of lateral branch board, and other end tenon is bumped in the groove of opposed inside support plate.The tenon place compresses with "T"-shaped strip briquetting between two sections grid sections of the vicinity of every shape being aligned, with the play that prevents grid section with beat, reaches the marginal portion of protection support plate simultaneously.After grid section uses, go up the adjusting that can replace of different abrasion conditions by whole section.

Fig. 4 is that Fig. 2 medial branch board B is to enlarged drawing

Among the figure: 1 lateral branch board, 2 medial branch boards, 3 bearing pins, 4 press strips, 5 grid sections, 6 briquettings, 7 trapezoidal holes, 8 dovetail grooves.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

When the utility model is implemented (accompanying drawing 2), have trapezoidal hole (7) (accompanying drawing 3) on the every lateral branch board (1), have dovetail groove (8) (accompanying drawing 4) on the medial branch board (2), each two of the inside and outside support plates of the utility model adopt general steel plate without exception.Grid section (5) adopts the good foundry goods of wearability, and whole is divided into two sections in this example, and every section intermediate cross-section is trapezoidal, and two ends are that the shape size is the same, and cross section is trapezoidal tenon.One section grid section (5) one end embeds trapezoidal hole (7), and trapezoidal hole is slightly larger than trapezoidal tenon so that assembling.For the play that prevents grid section (5) with beat, above trapezoidal hole, compress with the press strip (4) that is linked to lateral branch board (1); This section grid section (5) other end tenon is bumped into dovetail groove (8), equally along rectilinear direction, assembles another section.The tenon place compresses two tenons with "T"-shaped strip briquetting (6) between per two sections grid sections, use bearing pin (3) to be fixed on the medial branch board (2) again, "T"-shaped briquetting (6) adopts weldment, upper surface built-up welding hard material, and overlaying surface is not higher than the formed surface of grid section in a row.

Effect of the present utility model: the grid section simplified manufacturing process, it is convenient to change, and cost is low. Structure support plate is reasonable, increases operation rate, and especially suitable small lot batch manufacture is used.

Claims (3)

1, a kind of beater type disintegrating machine segmentation mosaic grid section body that is formed by connecting by the fixing grid section in a row of support plate is characterized in that every section grid section (5) one end tenons embed the trapezoidal hole (7) of lateral branch board (1); Other end tenon is bumped into the dovetail groove (8) of medial branch board (2), and tenon compresses with a briquetting (6).

2, grid section body according to claim 1 is characterized in that briquetting (6) is "T"-shaped strip shape body, its surface overlaying high-abrasive material, and briquetting (6) links with bearing pin (3) with medial branch board (2).

3, grid section body according to claim 1, lateral branch board (1) trapezoidal hole (7) top links press strip (4).
