Abstract
The utility model discloses a single disc impeller head, which comprises a protecting hood, a main shaft assembly and an impeller provided with a vane, wherein the impeller is provided with a slot along the radial direction, the surface of the impeller is provided with a pin hole communicated with the slot, one side of the vane is provided with a convex rib having the shape corresponding to that of the slot, the convex rib is provided with a pin ostiole corresponding to the pin hole, and the vane is inserted and connected inside the slot and is fixed on the impeller by a pin shaft passing through the pin hole and the pin ostiole. The impeller head has the advantages of convenient installation, disassembly and maintenance as well as high shot blasting efficiency.
Description
Technical field
The utility model relates to impeller blasting machinery equipment, is specifically related to a kind of table roller 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, quick abrasion, want frequent dismounting and change in the use, existing unit dish impeller head, its blade is connected on the impeller by bolt, and in the use, the screw thread of bolt is very easy is ground away, 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.Existing unit 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.In addition, existing unit dish impeller head, its blade are orthoscopic (dual-side of leaf cross-section be arranged in parallel), and the ball blast efficient of straight blade is low.
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 table roller 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 table roller impeller head of following structure, comprise guard shield, main shaft assembly and bladed wheel, its design feature is: it radially is provided with slot described impeller upper edge, the surface of impeller is provided with the pin-and-hole that is communicated with slot, one side of blade is provided with and the corresponding convex tendon of slot shape, and convex tendon is provided with and the corresponding lock-joint of pin-and-hole, and blade is plugged in the slot and by the bearing pin that pierces in pin-and-hole and the lock-joint and is fixed on the impeller.
After the utility model adopts said structure, during assembling, the convex tendon of blade inserted slot after, again bearing pin is injected pin-and-hole and passes lock-joint and can during detachable, bearing pin be ejected vanes fixed on impeller, blade extracted in the slot and gets final product.Because its pin-and-hole that radially is provided with slot and is communicated with of impeller upper edge with slot, one side of blade is provided with corresponding convex tendon of slot shape and convex tendon and is provided with and the corresponding lock-joint of pin-and-hole, therefore, the utility model adopts bolted prior art to compare with impeller blade, have and mount and dismount advantage easily, be convenient to maintenance and maintenance.
In order to improve ball blast efficient, the cross section of described blade is a cambered surface.
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 impeller blade shown in Fig. 1;
Fig. 3 is the cutaway view along A-A line among Fig. 2.
The specific embodiment
Table roller impeller head as shown in Figure 1 comprises 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 10, power is connected with shot wheel 11 on the bond pad 10, ring shot wheel 11 outsides are provided with the orienting cover 12 that is fixed on the guard shield 1, also be connected with on the guard shield 1 to the sand-guiding tube 13 of shot wheel 11 for steel sand, impeller 3 ring sets that blade 4 is housed are in orienting cover 12 outsides and affixed with bond pad 10, and the cross section of blade 4 is a cambered surface.As shown in Figures 2 and 3, it radially is provided with slot 5 impeller 3 upper edges, the surface of impeller 3 is provided with the pin-and-hole 6 that is communicated with slot 5, one side of blade 4 is provided with and the corresponding convex tendon 7 of slot 5 shapes, convex tendon 7 is provided with and pin-and-hole 6 corresponding lock-joints 8, and blade 4 is plugged in the slot 5 and by the bearing pin 9 that pierces in pin-and-hole 6 and the lock-joint 8 and is fixed on the impeller 3.Slot 5 is a dovetail groove, and convex tendon 7 is a swallow-tail form.The number of blade 4 can be decided according to instructions for use, generally is advisable with the 4-8 sheet.
