In order to realize the installation of the baffle 9 and the up-and-down movement of the baffle 9; a plurality of check rings 19 are arranged on the side wall of the material receiving barrel 6, and the baffle 9 can move up and down along the check rings 19; friction force exists between the baffle 9 and the retainer ring 19; the baffle 9 is fixed with a convex block 20; an upper limiting block 21 and a lower limiting block 21 are arranged on the side wall of the box body 4; when the receiving barrel 6 moves up and down, the convex block 20 can be blocked by the limiting block 21.

In order to facilitate the whole device to move back and forth on a reinforcing steel bar frame of a roof, the periphery of the base 1 is provided with an upward arc-shaped bending part.

In order to realize the extension and contraction of the discharge pipe 5, the discharge pipe 5 is a telescopic pipe.

When the device is used, the tail end of a pouring pipeline is placed on a roof to be poured through the telescopic arm by the tank car; then the device is placed below a pouring pipeline, and the tail end of the pouring pipeline is placed in a material receiving port 702 of a distributor 7 of the device. Because the size of the receiving opening 702 is much larger than the diameter of the casting pipe, the casting pipe can be allowed to have certain shaking and position deviation.

Then the device can disperse and pave the concrete conveyed by the pouring pipeline; the specific working principle and process are as follows.

Referring to fig. 2, the distributor 7 has two states, which are determined by the position of the internal block 703, and when the block 703 is at the left end, the distributor 7 will discharge to the right discharge port 705; similarly, by pulling the second cord 704 on the right side, the stopper 703 is moved to the right, so that the dispenser 7 is discharged from the discharge port 705 on the left side. Taking fig. 2 as an example, the concrete flows out through the right discharge port 705 and flows into the right receiving bucket 6.

When the right receiving barrel 6 is initially positioned at the uppermost part of the stroke, the baffle 9 on the receiving barrel 6 is in a state of closing the through hole 8; along with the increase of the inside concrete of right side joint storage bucket 6, the gravity that connects storage bucket 6 on right side can increase, and right side joint storage bucket 6 can descend this moment to it rises in step to drive left joint storage bucket 6 through first rope 13.

At this time, the second rope 704 on the right side is still in a loose state, the state of the distributor 7 is kept unchanged, the receiving barrel 6 on the right side continues to receive and descend, and simultaneously drives the guide rod 17 on the right side to descend, after the guide rod 17 descends, the lower end of the guide rod 17 extrudes the platform 23 to enable the platform 23 to descend, after the platform 23 descends, the rack 18 on the platform 23 is meshed with the one-way gear 16 to drive the rotating shaft and the first bevel gear 14 to rotate, and then the rotating shaft and the first bevel gear 14 are meshed through the second bevel gear 15, so that the vertical shaft 3 rotates relative to the support rod 2; the box body 4 above the vertical shaft 3 can be driven to rotate, and the distributor 7 and the like can be driven to rotate. The left and right discharge pipes 5 positioned below the box body 4 also rotate; the change of the discharging position of the discharging pipe 5 is realized.

Because the upper half of the rack 18 has no teeth and the lower half has teeth, the rack 18 can be meshed with the one-way gear 16 in the first descending half of the platform 23, and the non-teeth part of the rack 18 is meshed with the one-way gear 16 in the second descending half of the platform 23; the resistance of the whole receiving barrel 6 to descend is reduced; meanwhile, the gravity of the receiving barrel 6 is in a continuously increasing state; therefore, the descending speed of the receiving barrel 6 is suddenly changed; the descending speed of the rear end of the receiving barrel 6 is increased, and certain impulse is provided.

When the material receiving barrel 6 descends to the position close to the bottom, three actions are total at the moment:

1. the second rope 704 on the right side is quickly tensioned, so that the baffle 9 in the distributor 7 moves rightwards, and the distributor 7 switches states, so that concrete flows from the discharge port 705 on the left side to the receiving barrel 6 on the left side;

2. the baffle 9 on the side wall of the right receiving barrel 6 can be blocked by the limiting block 21 positioned below due to the convex block 20, so that the baffle 9 relatively moves upwards, namely the through hole 8 on the side wall of the right receiving barrel 6 is opened, and the concrete flows downwards into the box body 4; then flows out through the box body 4 and the discharge pipes 5 at the two sides;

3. the left charging barrel is pulled to synchronously rise to the highest position, and the baffle 9 on the side wall of the left charging barrel 6 moves downwards relatively at the moment, so that the through hole 8 is blocked. Through the cooperation of the three action of latter half end, can realize that right side connecting bucket 6 begins to unload, the change of 7 unloading directions of tripper, left side connecting bucket 6 resets. Thereby realizing the effect of completely switching the functional states of the left and right receiving buckets 6.

Through the concrete of arranging row material pipe 5 discharge on box 4, because row material pipe 5 can stretch out and draw back, consequently can be through lengthening row material pipe 5, make the concrete flow to farther region, realized the effect of spreading on a large scale. In addition, the length of the discharge pipe 5 is adjusted, so that the area within the coverage area of the discharge pipe 5 can be poured.

Meanwhile, when one receiving barrel 6 descends each time, the whole device can be driven to rotate for a certain degree, so that the rotation of the whole device can be driven by the self weight of concrete, and the pouring area can be automatically replaced; the manpower is further lightened.

The material receiving barrel 6 on the right side can gradually discharge materials, and the material receiving barrel 6 on the left side can gradually become heavy, so that the material receiving barrel 6 on the left side can repeat the process, slowly descend, and drive the whole device to rotate again. The baffle 9 on the right charging barrel can continuously keep the state of opening the through hole 8 due to the action of friction force, and the materials are fully discharged until the right receiving barrel 6 is restored to the highest position again; thereby realizing the internal automatic cycle work.

In conclusion, the whole descending process of the receiving barrel 6 is divided into three sections in the device; the first stage is as follows: a lifting stage for driving the guide rod 17 at the other side, and the lifting stage can enable the platform 23 to be reset upwards; in the second stage, the stage that the side guide rod 17 downwards extrudes the platform 23 can promote the whole device to rotate, the rotating angle does not need to be too large, and the insufficient pouring amount is avoided; in the third stage, the guide rod 17 of the side rapidly descends to the bottom stage, namely after the rack 18 continuously descends to be disengaged from the one-way gear 16, the distributor 7 is switched by pulling the second rope 704.

In the third stage, the descending resistance of the receiving barrel 6 is suddenly and greatly reduced by cutting off the meshing of the rack 18 and the one-way gear 16; the kinetic energy of the receiving bucket 6 when it descends can be increased, and this part of the energy is used for pulling the second rope 704 and overcoming the friction force when the baffle 9 moves up and down; the phenomenon that the pulling force of the second rope 704 is insufficient, so that the second rope is stuck can be avoided. The inside of the whole device can stably perform circulating work.

After pouring for a certain time in the same position, pouring in other areas can be carried out by moving the whole device, the periphery of the base 1 in the device is tilted upwards, the whole device can be conveniently moved back and forth on the reinforcing steel bar frame, and a certain paving effect is achieved. The device is far from enough relative to the whole roof coverage area, so the device needs to be moved in time; compared with the traditional method that when the pouring pipeline is directly aligned to a single position for pouring, concrete is accumulated, dozens of workers are needed to perform manual paving in a relay mode, the device greatly reduces manpower, can automatically and uniformly pave in a coverage range, does not need electric power, does not need wiring, and is not afraid of electric shock.

This device can connect the rope of a plurality of directions on base 1 when overall movement, stimulates through constructor all around, can realize that personnel do not go the roof central point and put, and realize the arbitrary removal of whole device, can effectually avoid the serious consequence that the roof landslide caused.

When the device is not needed to be used, clear water is needed to be used for washing in time, so that the concrete adhesion is avoided, and the follow-up use is influenced.
