Problems solved by technology

[0003] At present, almost all the equipment adopts piston-driven machinery. The existing piston mechanism does not have a buffer device, and the slurry is easy to form a pulse at the nozzle, resulting in very large pulsation, resulting in uneven spraying, which ultimately affects the spraying quality; and when the pressure is high It does not have the function of stopping at the time, it is easy to damage the sprayer, and even lead to safety accidents

Embodiment 1

[0017] like figure 1 As shown, the embodiment 1 is dedicated to the piston mechanism of the mortar spraying machine, including the piston 2 installed in the cylinder body 1, the cylinder body 1 is connected with a discharge assembly, and the discharge assembly is connected with a buffer mechanism.

[0018] The buffer mechanism in this embodiment 1 includes a sealing buffer 3, which not only plays the role of buffering, but also has a sealing function. The sealing buffer 3 is connected with a spring one 4 and a spring two 5, and the spring one 4 is connected with a travel switch. 6. Action shutdown, with the function of interlock shutdown when the pressure is high, and the spring 25 plays a buffer role.

[0019] The discharge assembly in the present embodiment 1 includes a discharge pipe 7, and a sphere one 8 and a sphere two 9 are installed in the discharge pipe 7, and the sphere one 8 and the two sphere 9 act together with the piston 2, and the vacuum principle is used to tak...

Embodiment 2

[0022] The buffer mechanism in this embodiment 2 is on the same level as the discharge pipe 7

[0023] The other components and their connection methods and working principles of the second embodiment are the same as those of the first embodiment, and will not be repeated here.

[0024] The invention is specially used in the spraying machine. On the one hand, its buffer mechanism greatly reduces the pulsation, making the spraying more uniform and improving the spraying quality; on the other hand, it is connected with a travel switch 6, which has the function of interlocking and stopping when the pressure is high, further improving The safety performance of the sprayer is guaranteed.

[0025] The invention has the advantages of simple structure and convenient use, and solves the difficult problems that cannot be overcome in the prior art.

Abstract

The invention discloses a special piston mechanism for a mortar sprayer. The piston mechanism disclosed by the invention comprises a piston body arranged in a cylinder body, wherein the cylinder body is connected with a discharging assembly; the discharging assembly is connected with a buffering mechanism; the buffering mechanism comprises a sealed buffering part to which a spring I and a spring II are connected; the spring I is connected with a travel switch. The special piston mechanism is mainly applied into the sprayer; on the one hand, by means of the buffering mechanism of the piston mechanism, the pulsation is greatly reduced, such that spraying is more uniform and the spraying quality is improved; on the other hand, the travel switch which is arranged in a connected manner has an interlocking shutdown function in case of high pressure, such that the safety performance of the sprayer is further improved. The special piston mechanism disclosed by the invention is simple in structure and convenient to use, and the problem which cannot be overcome in the prior art is solved.

Description

technical field [0001] The invention relates to a piston mechanism specially used for a mortar spraying machine. Background technique [0002] The spraying machine is a new type of high-efficiency construction machine. The equipment drives the machine to pressurize the slurry, sprays it out through the delivery pipe, spray gun, and nozzle instantly, expands and atomizes rapidly, and forms a coating on the surface to be sprayed. When this equipment is used in mortar plastering operations, the plastering layer has strong cohesive force, is not easy to hollow and crack, has high construction efficiency and low labor intensity. [0003] At present, almost all the equipment adopts piston-driven machinery. The existing piston mechanism does not have a buffer device. The slurry is easy to form pulses at the nozzle, resulting in very large pulsations, resulting in uneven spraying, which ultimately affects the spraying quality; and when the pressure is high When it does not have the...
