In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of an embodiment of the utility model;
Wherein: 1, frame; 2, hopper; 3, fuel tank; 4, control cabinet; 5, discharging opening; 6, go up fangs; 7, connection seat; 8, cylinder sleeve; 9, piston; 10, oil cylinder; 11, threeway; 12, go up ball sealer; 13, lower seal ball; 14, traction; 15, support; 16, fixed mount; 17, large cover; 18, minor flaps; 19, wheel.
The specific embodiment
As shown in Figure 1, a kind of hydraulic piston type pulp shooting machine comprises frame 1, hopper 2, fuel tank 3 and refractory gunning equipment, and wheel 19 is installed on the frame 1, also is provided with control cabinet 4 on the frame 1, and control cabinet 4 is polynary electric appliance control boxes; Hopper 2 is tapered hoppers, also is provided with support 15 and traction 14 on the hopper 2, supports 15 in the bottom of hopper 2, and traction 14 is arranged on the front side of hopper 2; Refractory gunning equipment comprises discharging opening 5, goes up fangs 6, connection seat 7, cylinder sleeve 8 and oil cylinder 10, and cylinder sleeve 8 is fixedlyed connected with frame 1 by fixed mount 16, is provided with piston 9 in the cylinder sleeve 8, and piston 9 is connected with oil cylinder 10 by connecting rod.The left end of connection seat 7 connects with cylinder sleeve 8 and internal communication forms confined space, and its upper end is connected with last fangs 6, and its lower end is connected with threeway 11, and connection seat 7 is provided with lower seal ball 13 with the junction of threeway 11, and threeway 11 lower ends are connected with hopper 2.The upper end of last fangs 6 is connected with discharging opening 5, and the junction of its lower end and connection seat 7 is provided with ball sealer 12; Last fangs 6 is provided with sealing ring with the junction of connection seat 7, and cylinder sleeve 8 is provided with sealing ring with the junction of connection seat 7, and fuel tank 3 is connected with oil cylinder 10.Last fangs 6 is provided with large cover 17, and connection seat 7 is provided with minor flaps 18, and the convenient inside to last fangs 6 and connection seat 7 of large cover 17 and little 18 design is cleaned through row.
Operating principle: what will stir is that the mortar of primary raw material is placed in the hopper 2 with the cement yellow sand, when oil cylinder 10 logical oil work, in the piston 9 back contracting strokes, in the space that connection seat 7 and cylinder sleeve 8 form, form negative pressure, last ball sealer 12 is the descending seal that compresses on the upper sealing panel under the atmospheric pressure effect, lower seal ball 13 is lifted under atmospheric action simultaneously, opens the seal of lower seal plate, makes mortar enter the space of connection seat 7 and cylinder sleeve 8 formation under atmospheric action.In piston protracted stroke, lower seal ball 13 is the descending lower seal plate that compresses under pressure and under the effect of self neutrality, and last ball sealer 12 is lifted using of high pressure, opened the seal of upper sealing panel, make mortar enter discharging opening 5 then by last fangs 6, and so forth, form continuous discharging.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
