Construction bolt connector in the through hole of described connection bump head and the through hole on the flange.

Have groove in the described connection bump head, nut is installed in the groove.

Described driving member has through hole, and a bolt passes described through hole and links to each other with the power transmission shaft of engine, clamps blasting vane wheel and blade between described bolt and the power transmission shaft.

Offer first through hole and second through hole in the described driving member, and offer a conduit at the second through hole edge, this driving member one end is set up flange, wherein,

The power transmission shaft of engine inserts in second through hole, and screw rod inserts driving member along first through hole, with power transmission shaft by being threaded the terminal interface that supports to first through hole and second through hole of screw rod;

Described flange place compresses blasting vane wheel, clamps securing member between blasting vane wheel and the blade, and screw head compresses blade;

Woodruff key is placed in the key position of power transmission shaft, is fixed in the conduit of driving member.

Also clamp cutter spacing between described blade and the securing member and regulate pad.

The beneficial effects of the utility model are: in the utility model, between engine and the cover basin terminal pad is installed, the sidepiece of terminal pad is offered vent notch, because terminal pad is a basin body, its joint face and air inlet face have very big spacing, have formed bigger admission space, and air-flow can be injected into blasting vane wheel in large quantities from vent notch, thereby can improve complete machine power greatly, improve result of use.

In the utility model, driving member has through hole, and a bolt passes through hole and links to each other with the power transmission shaft of engine, clamps blasting vane wheel and blade between bolt and the power transmission shaft, and its syndeton is simple, and cost is low, has further improved practicality of the present utility model.

In the utility model, have groove in the connection bump head, nut is installed in the groove, can accept the pressure that holding screw produces between terminal pad and the plastic jacket basin, thereby reach the effect of protection plastic jacket basin, further improved reliability of the present utility model.

Embodiment

With embodiment the utility model is described in further detail with reference to the accompanying drawings below:

According to Fig. 2 and Fig. 8, the utility model comprises engine 1, terminal pad 2, cover basin 3, driving member 4, blasting vane wheel 5 and blade 6.

As Fig. 2 and shown in Figure 8, between engine 1 and the cover basin 3 terminal pad 2 is installed, as Fig. 4 and shown in Figure 8, the sidepiece of terminal pad 2 is offered a plurality of vent notch 21.

As Fig. 2, Fig. 9 and shown in Figure 10, the bottom surface of terminal pad 2 is connected with cover basin 3, and the bottom surface 12 of the end face of terminal pad 2 and engine 1 fits.

Particularly, as Fig. 3 and shown in Figure 8, cover basin 3 has a blow vent 32, a plurality of connection bumps that have a through hole 33 are set up at these blow vent 32 edges, link 31 is set up at cover basin 3 tops, link 31 is used to connect support, pole of handrail and so on etc., so that use of the present utility model, operation.

As shown in Figure 4, via hole 24 is offered at the top of terminal pad 2, and flange 22 is set up on the base of terminal pad 2, offers on the described flange 22 and connection bump 33 a corresponding through hole 23.

As shown in figure 11, construction bolt 35 (head is assigned pad 34) in the through hole of connection bump 33 and the through hole 23 on the flange 22, nut 36 is installed in the groove of connection bump 33, and bolt 35 passes through hole 23 and is connected cover basin 3 and terminal pad 2 with nut 38 by pad 37.
