Abstract
The invention discloses a blowing and sucking machine provided with a volute protecting device. The blowing and sucking machine comprises a blowing and sucking machine body, the volute protecting device is arranged in a volute of the blowing and sucking machine body and comprises arc-shaped parts, first ends and second ends, wherein the first ends and the second ends are connected with the arc-shaped parts in a smoothing mode. The arc-shaped parts are similar to the volute in shape. The bottom surfaces, attached to the volute, of the arc-shaped parts are respectively provided with a flexible layer, and the front side edge of each first end extends downwards to form a shoulder part. According to the blowing and sucking machine, the volute can be effectively prevented from cracking, the flexible layers are arranged on the bottom surfaces of the arc-shaped parts so that the protecting device can be tightly attached to the volute, and pressure caused by stone impacting can be relieved. Clamping layers are arranged on the two side edges of each arc-shaped part to better fix the corresponding arc-shaped part in the volute. When an upper piece and a lower piece of the protecting device are in press fit, no displacement between the upper piece and the lower piece can be guaranteed, so that the volute is effectively prevented from cracking, and the service life of the blowing and sucking machine is prolonged.

The technical solution adopted in the present invention is: a kind of blower with spiral case protective device, is provided with reinforcement at the spiral case place of body.
Further, described body comprises left and right blower housing, is respectively equipped with the reinforcement that can fasten in the spiral case of left and right blower housing.
Further, described reinforcement comprises curved portions, first end and the second end, and described first end and the second end are connected with curved portions is smooth, and the shape of described curved portions is similar to volute shape, and described reinforcement end is provided with engaging support mechanism.
Further, described engaging support mechanism is for to be upwards provided with catch at first end dual-side, and described catch middle part is longitudinally provided with projection, and described projection is arranged in the same direction of two catch.
Further, described first end is inclined plane, and described the second end is parallel with horizontal plane.
Further, the dual-side of described first end is circular arc.
Further, the bottom surface of described curved portions and spiral case laminating is provided with soft layer.
Further, the front side edge of described first end is extended with shoulder downwards.
Further, described shoulder is taper.
Further, described the second end middle part is provided with screw.
The invention has the beneficial effects as follows: pressure-vaccum function of the present invention effectively prevents that spiral case from breaking, in the bottom surface of curved portions, being provided with soft layer can fit closely with spiral case protective device, and can also alleviate the pressure that stone impacts, at the dual-side of curved portions, being provided with clamping layer can be fixed in spiral case better, be provided with shoulder and can inject spiral case outside, can be first fixing one end, the other end is provided with screw, with fastened by screw, first end is provided with catch, in catch, be provided with projection, when pressing together, upper and lower two protective devices can guarantee not to be shifted between them, thereby can effectively prevent that spiral case from breaking, increase the application life of blower.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is the blower structural representation that the present invention has spiral case protective device;
