Modern most widely used general with the rotator type product, homemade goods has Pz5 type dry spraying machine, HPc6 type wet shot machine, and external product has: Furukawa Electronic's dry spraying machine, Switzerland A Liwa wet shot machine.
The rotator type concrete sprayer of existing widespread usage on the market, in use having deficiency is that plane clearance is sealed with obvious defects, the rotator type pulp shooting machine belongs to level pressure power forces the friction sealing, it is unreliable to seal, seal is changed difficulty, power consumption is high, dust is big, operating cost is high, and application life is short, and only have 50-70 hour application life.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, a kind of energy-saving and environmental protection, simple in structure, easy-maintaining, chain type concrete spraying machine that operating cost is low are provided.
Technical scheme of the present invention realizes in the following manner, its structure is by chassis, hopper, reductor, drive sprocket, by movable sprocket, piston cylinder and tandem piston are formed, drive sprocket is connected the right-hand member that is horizontally set on chassis with the power output shaft of reductor, be horizontally fixed on the left end of chassis by bearing support by the axle lower end of movable sprocket, be coaxially arranged with being arranged on by movable sprocket among the hopper of agitator, by movable sprocket and agitator among the hopper by a dividing plate at interval among two charging spaces up and down, the limit portion of dividing plate is provided with blanking hole, drive sprocket and be horizontally disposed with piston cylinder and wash bowl between the movable sprocket, tandem piston is cascaded by chain and passes piston cylinder and wash bowl and drive sprocket and linked together by movable sprocket, piston cylinder is provided with air intake and mouth spray, and wash bowl is provided with sparge pipe and delivery port.
Chain type concrete spraying machine of the present invention is compared with prior art, has following advantage:
1) this product is compared with rotator type, and sealing area has been dwindled thirtyfold;
2) this product is compared with rotator type, seal weight saving ten times;
3) this product adopts two-way lip bowl formula sealing, and the generation of thrust is to adjust the sealing force size automatically by spraying machine internal duct blast, has controlled self compensation ability, and promptly blast is big, and sealing force also strengthens thereupon, and sealing is reliable, can reduce plugging and return the wind fault.
4) this product has the suction of pressure feeding function, coefficient of admission height; Adapt to sticky material and carry, as steel fiber shotcrete and rotator type belongs to optional deadweight type feeding, can not carry sticky material, coefficient of admission is low, the emitted dose instability.

5, the specific embodiment
Below in conjunction with accompanying drawing chain type concrete spraying machine of the present invention is done following detailed description the in detail.
As shown in drawings, chain type concrete spraying machine of the present invention is by chassis 14, hopper 1, reductor 8, drive sprocket 12, by movable sprocket 4, piston cylinder 17 and tandem piston 11 are formed, drive sprocket 12 is connected the right-hand member that is horizontally set on chassis 14 with the power output shaft of reductor 8, be horizontally fixed on the left end of chassis 14 by bearing support 10 by the axle lower end of movable sprocket 4, be coaxially arranged with being arranged on by movable sprocket 4 among the hopper 1 of agitator 3, by movable sprocket 4 and agitator 3 among the hopper 1 by a dividing plate 22 at interval among two charging spaces up and down, the limit portion of dividing plate 22 is provided with blanking hole 23, drive sprocket 12 and be horizontally disposed with piston cylinder 17 and wash bowl 5 between the movable sprocket 4, tandem piston 11 is cascaded by chain 2 and passes piston cylinder 17 and wash bowl 5 and link together with drive sprocket 12 with by movable sprocket 4, piston cylinder 17 is provided with air intake 16 and mouth spray 15, and wash bowl 5 is provided with sparge pipe 7 and delivery port 6.
Be connected with motor 9 on the reductor 8, reductor 8 bottoms and chassis 14 are slidingly connected, and the right-hand member that is positioned at the reductor bottom is provided with chain 2 stretchers 18 and is connected with chassis 14 right-hand members.
Tandem piston is made up of chain fastener 19, piston ring 20 and lippacking 21, and piston ring 20 is fixed on lippacking 21 by self-locking nut the centre of chain fastener 19.
Operating principle of the present invention is as follows: motor via reducer is slowed down and is driven the drive sprocket rotation, tandem piston hangs over drive sprocket by the chain chain together and is formed the driving mechanism of tandem piston on the movable sprocket, on the path of tandem piston process piston cylinder and wash bowl are set respectively at drive sprocket and between by movable sprocket, piston cylinder is connected with concrete hopper, tandem piston pile warp hopper is constantly sent into concrete continuous in the piston cylinder, high-pressure blast import and concrete outlet are set on piston cylinder, continuously sealed chamber is from high pressure air port process because tandem piston is separated into piston cylinder, and pressure-air just blows out concrete and forms the concrete injection stream from outlet.The tandem piston of finishing transmission and concrete transmission is recycled to the wash bowl place, and rinse water is just cleaned tandem piston, and the tandem piston after clear is recycled to the process of carrying out in the hopper to the piston cylinder delivering concrete again.
For fear of relaxing of chain, be provided with and chain stretching device between reductor and the chassis, be used to adjust the degree of relaxing one's efforts of chain.
Chain type concrete spraying machine of the present invention is compared with existing technology, have reasonable in design, simple in structure, safe and reliable, long service life, be easy to safeguard, and volume is little, the short characteristics such as reinforcing laneway operation of being convenient to of vehicle body, this spraying machine adopts modularized design, thereby, be convenient to processing and install and keep in repair, greatly facilitate spraying operation, because air-tightness is good, improves well construction environment, has improved efficiency of construction. Also have frictional resistance little, in the situation of equal emitted dose, reduce power consumption more than 2/3rds. Resistance is little, wearing and tearing are little, noise is low, thereby long service life. Thereby, have good value for applications.
