Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 shows the structural representation of the nozzle mechanism of the Mortar spraying machine of one embodiment of the invention;
Fig. 2 shows the overall structure schematic diagram of the Mortar spraying machine of one embodiment of the invention;
Fig. 3 shows the cross-sectional view of the main apparent direction of the Mortar spraying machine of Fig. 2.
Detailed description of the invention
Details are as follows for structure of the present invention and feature by reference to the accompanying drawings.
With reference to the structural representation of the nozzle mechanism 80 of a kind of Mortar spraying machine of the one embodiment of the invention shown in Fig. 1, it comprises nozzle liner 82 and nozzle overcoat 84, described nozzle liner 82 is made up of high abrasion ceramic materials such as carborundum, but because this material is very wear-resisting more crisp, therefore be also arranged with nozzle overcoat 84 in the outside of nozzle liner 82, its material can be the nonmetals such as nylon.Described nozzle liner 82 can be placed in its inside when casting nozzle overcoat 84 is shaping as inserts.So, both ensure that the abrasion resistance that nozzle is high, and requirement of strength when meeting use.In addition, in a preferred embodiment, described nozzle mechanism 80 is set to the structure of two horn mouths back to splicing, and more excellent be pre-small post-large two horn mouths, back to the structure of splicing, so significantly can reduce the situation of spray nozzle clogging.
With reference to the overall structure composition schematic diagram of the Mortar spraying machine of the one embodiment of the invention shown in Fig. 2 and Fig. 3, Mortar spraying machine of the present invention comprises support 10, which is provided with power controling box (not shown), motor 16, speed-changing gear box 12, air pump 18; Be located at the support protective cover 20 on support 10 top; Be located at the travel wheel 30 of both sides, support 10 bottom; Be positioned at the hopper 40 of support 10 front portion, be provided with transmission long axis 42 in described hopper, described transmission long axis 42 is provided with multiple stirring vane 422; Be located at hopper 40 bottom front and the mortar transmission system 60 communicated with hopper 40; The high-pressure nozzle 70 be connected with transmission system 60 and be arranged on the above-mentioned nozzle mechanism 80 of high-pressure nozzle 70 front end, and be arranged on the jettron 76 near nozzle mechanism, the bottom of described hopper 40 is provided with feet 90.
