Abstract
The utility model relates to a blade quick-locking device of an impeller head, which comprises a blade seat and blades which are provided with a notch on the back; the notch is provided with an inner concave rabbet on the side near to a rotary center; the inner concave rabbet is clamped with a convex block on one side of the blade seat; the notch is provided with a concave pit on the other side far from the rotary center, and the lower end surface of an elastic member which is arranged in the blade seat abuts on the interior of the pit. The utility model can quickly remove and replace vulnerable blades and has the advantages of fast disassembly and replacement and great convenient installation, maintenance and operation.
Description
The utility model relate to a kind of impeller head blade mounting arrangement, especially relate to the fast locking device of blade of impeller head.
Impeller head is the heart of shot-blast apparatus, and it has determined the quality and the effect of impeller blasting to a great extent.Impeller head at work, the ball material is through being assigned to behind the shot wheel on each blade, by blade the ball material is thrown to surface of the work again, in this process, a large amount of ball material are impacting blade, though blade is made wearing piece, but blade is just necessary the replacing after approximately working 700 hours under impact of ball material and the friction, because of a plurality of blades are housed on the pill casting wheel, remove and change very inconvenience of vane operation, and inefficiency.
The purpose of this utility model provides a kind of blade and can remove fast, change, easy to operate impeller head the fast locking device of blade.
The utility model is that the technical scheme that achieves the above object is: the fast locking device of a kind of blade of impeller head, comprise blade seat and blade, there is notch at the back of blade, notch has the indent seam near the centre of gyration one side, and with the projection clamping of blade seat one side, notch has pit away from the opposite side of the centre of gyration, and the elastic component lower surface that is contained in the blade seat withstands in the pit.
The utility model adopts the advantage after the technique scheme to be: as the blade of consumable accessory, notch one side at its back has the indent seam, and with the projection clamping of blade seat one side, and also there is pit the another side of notch, the elastic component bottom that is contained in the blade seat is withstood in this pit, thereby blade utilizes elastic component to be connected with blade seat, blade is in rotary course, be subjected to the effect of the impulsive force of centrifugal force and ball material, blade and blade seat are connected firmly, remove and only need compression elastic piece when changing blade, make the projection disengaging on indent seam and the blade seat on the blade or be connected, blade just can draw off or install, need not other instrument, operation is very easy, increases work efficiency, and can load and unload blade fast.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of the utility model impeller head.
Fig. 2 is the I place structure for amplifying schematic diagram of Fig. 1.
Shown in Fig. 1～2, the fast locking device of the blade of impeller head of the present utility model, comprise blade seat 1 and blade 2, blade seat 1 is contained on the pill casting wheel 5, there is notch 3 at the back of blade 2, and notch 3 has indent seam 3-1 near the centre of gyration one sides, and with projection 1-1 clamping of blade seat 1 one sides, notch 3 has pit 3-2 away from a side of the centre of gyration, and elastic component 4 lower surfaces that are contained in the blade seat 1 withstand in the pit 3-2.Above-mentioned elastic component 4 can adopt as compression spring of Fig. 1 etc., the cylinder that also can adopt elastic caoutchouc post or other elastomeric material to make.
In order to improve the speed of dishing out of ball material, and make the further uniform distribution of ball material that drops on the blade 1, blade 2 as shown in Figure 2 is crooked arcuation along direction of rotation.
