Thus, the utility model has more reasonable structure and light weight. The utility model makes the fan-shaped structure of a friction plate changed into an integral structure, and ball iron materials of a lining board changed into high alloy materials. Thereby, the utility model can improve the service life and enlarge the elasticity of a material chamber. A vortex flow tube is arranged in an elbow tube so as to improve the ability of wet material processing. Thereby, the utility model can achieve the purposes that the utility model reduces fly dust, noise, back elasticity and maintenance cost, and is convenient to transport.

Description

Wet concrete sprayer

Technical field

The utility model belongs to building machinery, particularly a kind of wet concrete sprayer.Be widely used in mine working, in the engineerings such as tunnel culvert, subway, water power, military project people's air defense, ground bank protection.

Background technology

Up to the present wet concrete sprayer, all is rotator type basically, and it is divided into top discharge and two kinds of types of bottom discharge.Though through test, the research of decades, through tens times improvement, its structure does not become substantially both at home and abroad, performance improves few, therefore, produces little effect.

The weak point of existing type mainly is: its transmission mechanism is vertical machine, drives the rotor rotation by cylinder gear speed reducer, thereby carries out work.Because vertical machine and rotor system are arranged in parallel, and can not reduce its spacing again, so change in any case, structure can not change too big, and the usefull space can not make full use of, and structure is very unreasonable, and complete machine weight reduces not obvious; Above discharging structure is an example, and the outer rubber for the meridian parcel in the material chamber of rotor is made, and little because of pressure-bearing elasticity, the ability of handling wet feed is not ideal enough; Friction plate is fan-shaped, and liner plate is the magnesium iron material, and application life is shorter.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art part, changes traditional structural shape, makes it more reasonable, reduces complete machine weight greatly, in order to carrying; Improve the application life of consumable accessory and the ability of processing wet feed, reduce dust, noise, reduce resilience and maintenance load, save maintenance cost thereby reach.

The utility model is achieved by the following technical solution: a kind of wet concrete sprayer, have motor, reductor, rotary body, discharging elbow, hopper, vibrator, friction plate, liner plate, it is characterized in that motor is horizontal, reducer is a bevel gear reducer, the output shaft of motor by belt pulley pay on the bevel gear reducer output shaft external gear and and the internal gear of the rotary body bottom that is meshed of external gear constitute, make the transmission mechanism of rotary body rotation; Or the output shaft of motor directly is connected with bevel gear reducer; The material chamber place a rotating body groove and with groove around gapped; Device has cyclone pipe in the discharging elbow, and friction plate is the monolithic disc, compresses with being distributed on rotary body radial type hold down gag on every side.

Described cyclone pipe is a bend pipe, at its periphery wall helix is arranged.

Owing to adopted said structure, machine volume is little, in light weight, long service life.And reduced dust, noise, reduced resilience and maintenance load.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model structural representation;

Fig. 2 is the friction plate structure chart;

Fig. 3 is the cyclone pipe structure chart;

Fig. 4 is the transmission mechanism schematic diagram.

Among the figure: 1, reductor, 2, frame, 3, rotary body, 4, the material chamber, 5, liner plate, 6, friction plate, 7, setting gauge, 8, screen cloth, 9, hopper, 10, hold down gag, 11, vibrator, 12, elbow, 13, belt pulley is paid, and 14, the main air road, 15, air path system, 16, help wind path, 17, cleaning wind path, 18, motor, 19, wheel, 20, pressure ring, 21, cyclone pipe, 22, external gear, 23, internal gear, 24, helix.

The specific embodiment

As shown in Figure 1, reductor 1, motor 18 are fixed on the

frame

2, and 4 wheels 19 are housed in the bottom so that carrying.As shown in Figure 4,

Motor 18 is paid 13 external gears 22 through conical gear reducer 1 output shaft top by belt pulley, passes to the internal gear 23 of rotary body 3 bottoms, makes rotary body 3 rotations, carries out work.This design, utilized dexterously belt pulley pay 13 and the space of rotary body 3 bottoms carry out twice deceleration, make conical gear reducer have only double reduction, so its volume ratio was much smaller originally, and was light; Material chamber 4 places in the rotary body 3, and all gapped all around, and adopts the wearing plate soft rubber to make.Because of pressing wind system intermittently to blow the material of expecting in the chamber 4, force material chamber 4 intermittently to rise, contract, the probability of sizing is significantly reduced; Friction plate 6 has material-dropping hole 6-1, fresh air inlet 6-2 as shown in Figure 2 with the original fan-shaped overall structure that changes into above the disc, discharge opening 6-3, above sealing performance better, longer service life; The material of liner plate 5 changes the high alloy material into by original magnesium iron, and its life-span is improved several times; In elbow 12 bottom holes, increased a cyclone pipe.

As shown in Figure 3, there is helix the cyclone pipe outside, and by the pressure wind that helps wind path 16 to come in, wind cleans attachment along the inwall generation eddy flow of elbow 12 during by helix, causes the phenomenon that produces sizing in the elbow to reduce greatly, has improved the ability of outer reason wet feed; Around

rotary body

3,4 uniform hold down gags 10 are arranged, the sealing performance that is used to compress, regulate friction plate 6, more far better than the original sealing that only compresses, regulates friction plate 6 with two bolts.

Manually with the stir material chamber 4 that enter rotary body 3 in of compound (rubble, sand, cement, powder accelerator) through the vibration of screen cloth 8, vibrator 11, setting gauge 7, because the rotation of rotary body 3, compound is placed the bottom of elbow 12, the pressure wind of coming in by air path system 15, enter elbow 12 through main air road 14, deposit elbow 12 bottoms in expect in the chamber 4 compound, via conveying pipeline, shower nozzle sprays to and is subjected to spray plane.According to circumstances add low amounts of water at the shower nozzle place by spraying hand.For preventing that running wind in spraying journey flies material, below the fixed pressure ring 20, connecting by rubber or polyurethane and making friction plate 6, be distributed in the degree that compresses of 4 hold down gags 10 around the rotary body 3 by adjusting, reach the effect of sealing.This method only compresses with two bolts than original, and its performance is far better.For reducing at the exit of elbow 12 sizing, the pressure wind by air path system 15 is come in enters the helix of the cyclone pipe (Fig. 3) in the elbow 12 through helping wind path 16, produces eddy flow, is used to clean the sizing of elbow 12 heads.After hours, blow clean, to keep the clean and tidy of machine with cleaning wind path 17 residue that machine is inside and outside.

Place the material chamber 4 in the rotary body 3, all gapped around it, intermittently blow the material of expecting in the chamber 4 because of pressing wind system, force the material chamber 4 generation elasticity that continues to rise, contracts, adding has increased a cyclone pipe in elbow 12, so, the probability of sizing significantly reduces, and the ability of handling wet feed strengthens greatly.
