Detailed description of the invention
Details are as follows for the structure of Mortar spraying machine of the present invention and feature by reference to the accompanying drawings.
With reference to Fig. 1, Fig. 2 and Fig. 3, the Mortar spraying machine with safety relief mechanism of one embodiment of the 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 main shaft 42 in described hopper, described transmission main shaft 42 is provided with multiple stirring vane 422, be located at hopper 40 bottom front and the mortar transmission system be connected with hopper 40, the jet pipe 70 be connected with transmission system and be arranged on the nozzle 80 of jet pipe 70 front end, the bottom of described hopper 40 is provided with feet 90, wherein, described speed-changing gear box 12 is connected by eccentric drive mechanism 14 one end with transmission main shaft 42 and is driven it to move back and forth, described transmission system comprises the material conveying tube 62 be arranged on bottom hopper 40, first three way cock 64, second three way cock 66, one end of described material conveying tube 62 communicates with bottom hopper, the other end is connected with the bottom valve port A of the first three way cock 64, the other end of described transmission main shaft 42 is connected with piston 44, the side end valve mouth C of the first three way cock 64 is connected with the cylinder sleeve 46 coordinated with described piston 44, the upper end valve port B of the first three way cock 64 is connected with the lower end valve port of the second three way cock 66, one end of described jet pipe 70 is connected with the side end valve mouth of the second three way cock 66, the opposite side end valve mouth of the second three way cock 66 is provided with relief valve 72, and relief valve 72 is communicated by the top of pipeline with hopper 40.
With reference to diagram, the operating principle of Mortar spraying machine of the present invention is as follows: speed-changing gear box 12 drives transmission main shaft 42 to move back and forth by eccentric drive mechanism 14 under the drive of motor 16, when transmitting main shaft 42 driven plunger 44 and moving to the left direction in Fig. 2, the valve port A of the first three way cock 64 closes, valve port B opens, and the air of the first three way cock 64 inside is discharged from valve port B through the second three way cock 66; When transmitting main shaft 42 driven plunger 44 and resetting to the direction, the right in Fig. 2, the valve port A of the first three way cock 64 opens, and valve port B closes, and due to the negative pressure of the first three way cock 64 inside, the mortar of hopper 40 inside enters the first three way cock 64 inside from material conveying tube 62; When transmitting main shaft 42 driven plunger 44 and again moving to the left direction in figure, the mortar of the first three way cock 64 inside is just transported in the second three way cock 66 and jet pipe 70, and mortar sprays from nozzle by the pneumatic type automatic electric switch 76 (as shown in Figure 5) of operating personnel namely by controlling jet pipe 70 other end.So, moved back and forth by transmission main shaft 42 driven plunger, the mortar of hopper 40 inside constantly can be transported to jet pipe 70 and be ejected to operation metope.
In an embodiment of the present invention, described transmission main shaft 42 is provided with multiple stirring vane 422, and in the reciprocatory movement of transmission main shaft 42, stirring vane 422 ceaselessly can stir the mortar of hopper 40 inside, prevents its precipitation or solidifies.
With reference to Fig. 4, described relief valve 72 is provided with switch knob 74, and when Mortar spraying machine normally works, relief valve is closure state; When needing the mortar of cleaning blocking, by switch knob, relief valve is opened with release pressure, and then by the cleaning of residual mortar, enter hopper 40 by pipeline.
In addition; when Mortar spraying machine general at present works; often construction site and Mortar spraying machine distant; if when operation midway needs to shut down cleaning blocking; generally operator is all needed to walk back the stand of Mortar spraying machine from construction site by power-off, and in the process, Mortar spraying machine or in running order; continuing to consume electric energy, than being easier to, security incident occur in addition.Therefore, Mortar spraying machine of the present invention have employed pneumatic type automatic electric switch 76, see Fig. 5, described pneumatic type automatic electric switch 76 is installed on the place of jet pipe 70 close to nozzle 80, its one end is connected with air pump, and the other end to be communicated with nozzle by ventilating pipe 78 and controls to discharge gases at high pressure to nozzle place; And described pneumatic type automatic electric switch 76 is connected with power controling box, when pneumatic type automatic electric switch 76 cuts out, described power controling box stops the power supply of Mortar spraying machine.Therefore, when needing in operation process to shut down, only needing pneumatic type automatic electric switch 76 to close, power controling box can be closed, stop the power supply of Mortar spraying machine, then operating personnel carries out the cleaning work that blocks again, guarantees to produce security incident.
In an additional preferred embodiment, be provided with vibrosieve 50 on described hopper 40 top, the bottom of described vibrosieve 50 is provided with screen cloth 52; Vibrosieve 50 place is provided with motor 54, described motor 54 can drive vibrosieve 50 to vibrate, so, when vibrosieve 50 poured into by the mortar mixed, by screen cloth, the stone of larger particles, foreign material etc. can be sifted out from mortar, prevent the stone of these larger particles, foreign material etc. from causing damage to the component of flush coater inside and causing the blocking of pipeline or nozzle.
In sum, Mortar spraying machine of the present invention is the high mortar spraying machinery of a security performance, farthest can avoid the generation of security incident, and controls convenient, and the efficiency of operation is high.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
