Description
The utility model relates to a kind of pulp shooting machine, particularly relates to a kind of pulp shooting machine of wind control mechanism of the whitewashing operation of controlling pulp shooting machine.
Pulp shooting machine is that present building, construction industry are used favourable machine splendid when the cement paste construction of wall panel, though pulp shooting machine can make the process of the thick embryo construction of wallboard enter mechanization, and the saving manpower, and raising work effect, but, on function, but still have many desirable not to the utmost places to need to improve with the pulp shooting machine that is adopted on the market at present.
With comparatively widely used on the market pulp shooting machine at present, no matter the power resources of pulp shooting machine are to adopt power motor or engine power, all need to cooperate one group of pneumatic shuttle, and will be stressed the cement mortar of output in the pulp shooting machine, be blended in the inner space of a spray gun, the gases at high pressure that utilize pneumatic shuttle to export again are emitted into diffusion type with cement mortar by spray gun, with the handled easily person cement mortar are uniformly sprayed on wallboard to be constructed.Yet general pulp shooting machine in the past is to place on the ground in the use, utilizes an extension to be connected on the wallboard of wanting spray water mud again, and the length of extension have reach hundred meters, also have and be short to tens of meters; So, often the distance of Pen Jiang operating personnel and pulp shooting machine is tens of or hundred meters far away, this segment distance is concerning the whitewashing operating personnel, be very inconvenient, for example, when operating personnel will begin to do the construction whitewashing of metope, needs elder generation was switch activated with pulp shooting machine, make pulp shooting machine extrusion cement mortar, cement mortar can flow along extension; Then, operating personnel pick up spray gun to the end of extension again, push the switch of pneumatic shuttle on the spray gun, the gases at high pressure of pneumatic shuttle are sneaked in the spray gun cement mortar is sprayed.
Thus, we can find after operating personnel are starting the pulp shooting machine running, cement mortar in the pulp shooting machine will be stressed via spray gun and flow out, and after pushing pneumatic shuttle, just can form the action of whitewashing, so operating personnel open pulp shooting machine to pick up spray gun during this period of time in, will cause cement mortar under unwatched situation, to pour off; Opposite, when operating personnel will turn off pulp shooting machine, the situation that is produced also can be the same.Therefore, in general, a pulp shooting machine often needs two people and cooperates when operation, that is to say that a people controls the switch of pulp shooting machine, and a people controls the operation of spray gun.
