Description

Concrete feeding and mixer

technical field

The utility model relates to the technical field of engineering construction, in particular to a wet concrete feeding and agitator.

Background technique

At present, concrete spraying machines at home and abroad are divided into dry spraying machines and wet spraying machines. Dry spraying machines send powdery materials into the spraying machine. There are multiple material cups in the spraying machine. Next, spray from the material cup into the discharge elbow, into the material delivery pipe, and add water to the nozzle of the delivery pipe to mix the material with water. The disadvantage of this type of sprayer is that the material is not mixed uniformly. , the rebound force of the material sprayed onto the construction surface is large (dry, the rebound is large, and it is easy to flow when wet). Under the force of the compressed gas, the sprayer generates a large amount of dust, which is harmful to the human body and easily causes dust disease. .

A wet concrete spraying unit as shown in Figure 1, which includes a movable fuselage, on which a stirring cage 6, a spraying mechanism 11, a spraying machine mounting plate 12, an accelerator box 13 and an accelerator are installed. Pump 14, a screw mixing conveying system 5 is housed in the described mixing cage 6, and one end of the screw mixing conveying system 5 is connected with a motor 7 through a transmission wheel 9, and a cement hopper 1, a sandstone hopper 2, Water adding device 4, discharge port 10 and cleaning discharge port 15, described stirring cage 6 is installed obliquely from tail end to front end, the bottom of described cement hopper 1, sandstone hopper 2 and described stirring cage 6 tails The end is connected and communicated with the screw agitating conveying system 5, the vibrator 3 is installed on the sand hopper 2, the front end of the screw agitating conveying system 5 has the discharge port 10, the discharge port 10 is installed above the spraying mechanism 11 and communicates with the spraying mechanism 11. When working, cement and sand are fed into the cement hopper 1 and sand hopper 2 respectively, and are stirred by the screw mixing conveying system 5 to form concrete, and then enter the spraying mechanism 11 from the discharge port 10 by means of the screw conveying effect. At this time, the spraying mechanism Enter the high-pressure air, spray the concrete slurry material from the spray gun of the spray mechanism, and spray it on the working surface. In the injection unit with the above structure, the injection mechanism 11 is composed of the injection machine body and the scraper mechanism. The scraper mechanism is arranged above the injection machine body. When working, the concrete output from the screw mixing conveying system 5 is sent to the scraper. In the mechanism, the concrete can only enter the sprayer body after being scraped by the rotating blades in the scraper mechanism, and the concrete is sprayed by the sprayer body. The injection mechanism 11 of this structure, because the scraper mechanism is arranged on the injection machine body, makes the overall height of the injection mechanism 11 become higher, not only is unfavorable for reducing the space occupied, but also raises the outlet of the screw agitating conveying system 5. The height of the feed port requires a high-power motor to drive the screw mixing conveying system 5, which is not conducive to cost saving.

After assembly, the rubber belt is located between the steel belt and the first brake disc, and the length of the steel belt is greater than the length of the rubber belt. Therefore, the first brake belt 44 is respectively connected to the tensioning block 43 and the connecting block 48 through the two ends of the steel belt. .

As shown in FIG. 3 and FIG. 4 , the sliding sleeve 45 is sleeved on the rotating shaft 6 , and the push-pull device is fixedly connected with the sliding sleeve 45 . One end of the sliding sleeve 45 is conical, and the other end is cylindrical. When the conical end of the sliding sleeve 45 is used to generate an active force on the free end of the tightening block 43 during the sliding process, the tightening block 43 takes the hinge point as the The supporting point rotates, so that the dialing block 43 exerts a pulling force on the first brake band 44 , so that the first brake band 44 is tightly attached to the first brake disc 47 . The push-pull device includes a shaft sleeve 49, a joystick 50, and a shift fork 51. The shaft sleeve 49 is arranged on the base 5. One end of the shift fork 51 with a fork is connected to the sliding sleeve 45.

The clutch 4 is not limited to the above-mentioned structure, and for example, a jaw clutch can also be used.

The working process of this part is: when the material needs to be loaded, start the driving device 8, the power output by the driving device 8 drives the rotating shaft 6 to rotate through the transmission mechanism, at this time, push the joystick 50 to make the sliding sleeve 45 move towards the direction of the fixed plate 42 Displacement, sliding sleeve 45 is in the process of displacement, and its conical surface produces extruding force on the free end of dial tightening block 43, and dial tightening block 43 rotates with hinge point as support point, like this, dial tightening block 43 to the first A brake band 44 exerts tension, so that the first brake band 44 is tightly attached to the first brake disc 47 . Since the fixed disc 42 is fastened on the shaft, the fixed disc 42 rotates following the rotating shaft 6. Therefore, when the first brake band 44 is closely attached to the first brake disc 47, the action generated by the rotation of the fixed disc 42 passes through The first brake disc 47 is transmitted to the first brake disc 47, the first brake disc 47 rotates, thereby the housing 41 rotates, the wheel disc 46 winds the rope 3, and the upper hopper 1 is centered on the hinge point with the support 2 Rotation occurs, so that the material in the upper hopper 1 is sent into the mixing bucket 7 . When the rotating shaft 6 rotates, the power of the rotating shaft 6 is transmitted to the mixing drum 7 through the friction between the supporting wheel 9 and the mixing drum 7. Therefore, when the driving device 8 is started, the mixing drum 7 starts to rotate. Once the material enters the In the mixing tank 7, the mixing can be carried out, and the materials are fully mixed and stirred in the mixing tank 7, which can significantly improve the quality of the concrete. The utility model connects the feeding hopper and the stirring device through the clutch, which not only saves the space occupied by a single feeding hopper, but also makes the two share a driving device, which is beneficial to reduce the equipment cost.

After the feeding is completed, it is necessary to put the loading hopper 1 down to carry out material hopper loading, so as to prepare for feeding the mixing tank 7 next time. At this time, push the control lever 50 to make the sliding sleeve 45 displace in the opposite direction of the fixed plate 42. In this way, the pressing force of the sliding sleeve 45 on the tightening block 43 is released, and the first brake band 44 is in a loose state. A brake disc 47 cannot obtain power. In a normal state, due to the preloading force of the spring 56, the second brake band 53a produces a restraining force on the second brake disc 53 (the restraining force is less than the power output by the driving device). , the shell 41 cannot be rotated by the binding force. Continue to push the joystick 50, the jacking part 57 that is connected on the joystick 50 produces upward active force to the connecting rod 55, like this, the connecting rod 55 is lifted by the jacking part 57, makes the first brake disc 53 on the second The second brake band 53a is in the loosening device, thereby releasing the second brake band 53a from the restraint of the second brake disc 53, because the first brake disc 47 and the second brake disc 53 are not bound, therefore, the gravity of the upper hopper 1 Under the action, the casing 1 can be reversed, so that the upper hopper 1 can be lowered.
