Abstract
The utility model discloses a double-disc impeller head, which comprises a protecting hood, a main shaft assembly and an impeller provided with a vane, wherein the impeller comprises a main disc and asecondary disc which are connected into a whole body by a support pole arranged between the main disc and the secondary disc; the main disc is provided with a slot along the radial direction and a sediment groove along the axial direction, and the sediment groove is communicated with the inner end of the slot; the secondary disc is also provided with a slot and a sediment groove which have the positions corresponding to those on the main disc; and the two sides of the vane are respectively provided with convex ribs having the shape corresponding to that of the slots, and the inner end of theconvex rib is provided with bumps corresponding to the sediment groove. The impeller head has the advantages of convenient installation, dismantling and maintenance.
Description
Technical field
The utility model relates to impeller blasting machinery equipment, is specifically related to a kind of pair of disk impeller head.
Background technology
In impeller blasting machinery equipment industry, impeller head is most critical, topmost parts, also is parts of performance benefit maximum in equipment, and speed, the quality of entire equipment performance effect size, cleaning workpiece all depend on impeller head.The blade of impeller head itself belongs to a kind of consumable accessory, and quick abrasion is wanted frequent dismounting and change in the use.Existing double base dish impeller head, impeller is made of main disk and secondary disk, main disk and secondary disk are connected as a single entity by the pillar between the two, its blade pass is crossed bolt and is connected on main disk and the secondary disk, in the use, the screw thread of bolt is very easy to be worn, and it is time-consuming to cause the installation and removal of blade relatively to be required great effort, and brings very big difficulty for maintenance and maintenance work.In addition, existing double base dish impeller head, its main shaft assembly and impeller head housing are split type, promptly are separately fixed on the frame of impeller blasting machinery, mount and dismount also pretty troublesomely, relatively waste time and energy.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, provides a kind of installation and removal of blade convenient, is convenient to the double base dish impeller head that keeps in repair and maintain.
In order to solve the problems of the technologies described above, the utility model provides a kind of two disk impeller heads of following structure, comprise guard shield, main shaft assembly and bladed wheel, impeller is made of main disk and secondary disk, main disk and secondary disk are connected as a single entity by the pillar between the two, its design feature is: it radially is provided with slot described main disk upper edge, it is axially arranged with the deep gouge that is communicated with the inner of slot the main disk upper edge, also be provided with corresponding slot in position and deep gouge on the secondary disk, the both sides of blade respectively are provided with and the corresponding convex tendon of slot shape, and the inner of convex tendon is provided with and the corresponding projection of deep gouge.
After the utility model adopts said structure, during assembling, the centre bore of blade impulse impeller, promptly the centre bore from secondary disk pushes blade in the impeller, and the slot that the convex tendon of blade both sides is inserted respectively on main disk and the secondary disk gets final product then, just can carry out work connecting the back with associated components in the impeller threading guard shield that installs blade, during ball blast, blade is with the impeller high speed rotating, under action of centrifugal force, projection is pressed in the deep gouge, prevents that blade is thrown out of.During detachable, impeller is drawn off, blade just can skid off in slot, blade is taken out to get final product then.Drawn by above-mentioned being not difficult, the utility model adopts bolted prior art to compare with impeller blade, has to mount and dismount advantage easily, is convenient to maintenance and maintenance.
Convenient for impeller head is mounted and dismounted on the frame of impeller blasting machinery, described main shaft assembly is fixed on the guard shield.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembly structure schematic diagram of the impeller blade shown in Fig. 1;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is the cutaway view along A-A line among Fig. 2.
The specific embodiment
Two disk impeller heads as shown in Figure 1 comprise guard shield 1 and main shaft assembly 2.Main shaft assembly 2 is fixed on the guard shield 1, the output power of the power transmission shaft of main shaft assembly 2 is connected with bond pad 11, power is connected with shot wheel 12 on the bond pad 11, ring shot wheel 12 outsides are provided with the orienting cover 13 that is fixed on the guard shield 1, also be connected with on the guard shield 1 to the sand-guiding tube 14 of shot wheel 12 for steel sand, impeller 3 ring sets that blade 6 is housed are in orienting cover 13 outsides and affixed with bond pad 11.
As Fig. 2, Fig. 3 and shown in Figure 4, impeller 3 is made of main disk 4 and secondary disk 5, main disk 4 and secondary disk 5 are connected as a single entity by the pillar between the two 15, main disk 4 is fixed on the bond pad 11, it radially is provided with slot 7 the medial surface upper edge of main disk 4, it is axially arranged with the deep gouge 8 that is communicated with the inner of slot 7 the medial surface upper edge of main disk 4, also be provided with corresponding slot 7 in position and deep gouge 8 on the secondary disk 5, the both sides of blade 6 respectively are provided with and the corresponding convex tendon 9 of slot 7 shapes, and the inner of convex tendon 9 is provided with and deep gouge 8 corresponding projections 10.The convex tendon 9 of blade 6 by its both sides is plugged in the slot 7 of corresponding setting on main disk 4 and the secondary disk 5, to realize and being connected of impeller 3.When blade 6 rotated with impeller 3, in action of centrifugal force lower edge impeller 3 radial slippage, final projection 10 can sink in the deep gouge 8 blade 6 is spacing.The number of the number of blade 6 and corresponding slot 7 and deep gouge 8 can be decided according to instructions for use, and blade 6 generally is advisable with the 4-8 sheet.
