Problems solved by technology

The efficiency of manual spraying is too low. It is not often used in construction. Mechanical automatic cement slurry spraying is used more frequently, and the accompanying cement slurry spraying devices are also emerging in endlessly.
However, there is a problem with the mechanical cement slurry spraying device: due to the stickiness of the cement slurry, the spray holes are easy to block. When the nozzles (spray holes) are blocked during the spraying process, it is necessary to manually clean (poke, poke) the nozzles one by one ( Spray hole), the disadvantage is low efficiency and inconvenient operation (splash the whole body when artificially approaching), so a device or mechanism that is convenient to clean and solve the blockage of the nozzle (spray hole) is needed to solve the above problems

Embodiment 1

[0020] Such as figure 1 with figure 2 As shown, an anti-clogging device for a cement slurry spraying pipe includes a spraying pipe 1, a hinged rod 4 and an anti-clogging mechanism, the spraying pipe 1 and the hinged rod 4 are parallel to each other, and the rear end of the spraying pipe 1 is connected to a plurality of fixed plates 2 arranged at intervals , the spray pipe 1 between every two fixed plates 2 is provided with spray holes that run through the front and rear ends of the spray pipe 1, the same position on each fixed plate 2 is provided with hinged holes 3, and the hinged rods 4 connect from each hinged hole 3 The hinged rod 4 is connected with a plurality of anti-clogging devices, and each anti-clogged device corresponds to a spray hole. One end of the hinged rod 4 is also connected with a handle rod 8, and the handle rod 8 is connected with a handle ball 9. The blocking device includes an ear seat 5 connected to the hinge rod, a small connecting rod 6 is hinged o...

Embodiment 2

[0025] Such as figure 1 with figure 2 As shown, on the basis of Embodiment 1, two limiting blocks 10 are connected to the fixed plate 2 , and a stopper 11 is connected to the hinge rod 4 , and the stopper 11 is located between the two limiting blocks 10 .

[0026] The two limiting blocks 10 are distributed along the periphery of the hinge hole 3 on the fixing plate 2 .

[0027] Two stoppers 10 are connected on one side of the fixed plate 2, and the two stoppers 10 are distributed along the periphery of the hinge hole 3, and the stopper 11 on the hinge rod 4 is stuck in the middle of the two stoppers 10, so that the rotation When the hinge rod 4 is hinged, the stopper 11 will be locked by the front and rear two limit blocks 10 to prevent the hinge rod 4 from turning too much, and the angle between the two limit blocks 10 can be within 100 degrees.

[0028] A torsion spring 12 is also connected to the handle bar 4 , and the other end of the torsion spring 12 is connected to t...

Embodiment 3

[0036] Such as Figure 1 to Figure 3 As shown, on the basis of Example 2, a method for using a cement slurry spray pipe anti-clogging device, in the default state, the hole needle 7 is inserted from the spray hole at the rear of the spray pipe 1, and the front end of the sealing sleeve 13 on the hole needle 7 pushes Seal the spray hole at the rear to realize the sealing. When working, push the handle rod 8 to the direction of the spray pipe 1, the handle rod 8 drives the hinge rod 4 and the ear seat 5 on it to rotate, and the ear seat 5 drives the small connecting rod 6 to move, and the small connecting rod 6 moves. The lower end of the connecting rod 6 advances forward and pushes the needle 7 into the spray pipe 1 until the front end of the needle 7 protrudes from the spray hole at the front end of the spray pipe 1 to clean up the blockage in the spray hole at the front end, and then loosen the handle 8. Under the action of the torsion spring 12, the handle rod 8 drives the h...

Abstract

The invention provides an anti-blocking device for a cement paste spraying pipe and a using method. The device comprises a spraying pipe, hinge rods and anti-blocking mechanisms, the rear end of the spraying pipe is connected with a plurality of fixing plates arranged at intervals, and a spraying hole penetrating through the front end and the rear end of the spraying pipe is formed in the sprayingpipe between every two fixing plates. Hinge holes are formed at the same positions of the fixing plates, the hinge rods penetrate through the hinge holes, and the plurality of anti-blocking devices are connected to the hinge rods. Each anti-blocking device corresponds to one spraying hole, one end of each hinge rod is further connected with a handle rod, and the handle rod is connected with a handle ball. Each anti-blocking device comprises a lug connected to the hinge rod, a small connecting rod is hinged to the lug, and a hole needle is hinged to the other end of the small connecting rod and is inserted into the spraying hole from the spraying hole at the rear end. The hole needles are driven to retreat from and stretch into the spraying pipes by rotating the hinge rods, and the hole needles penetrate through the spraying holes at the front end, so that the spraying holes are prevented from being blocked. Meanwhile, the hole needles of the multiple anti-blocking devices clean the spraying holes at the same time, so that the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of paver, and in particular relates to a cement slurry spray pipe anti-blocking device and a using method. Background technique [0002] In the construction of the stabilized soil pavement base, in order to improve the quality of the cement concrete pavement, cement slurry is generally sprayed between the upper and lower layers to improve the adhesion between the mixture layers. The work of spraying cement slurry includes manual spraying and automatic spraying of mechanical devices. The efficiency of manual spraying is too low. It is not often used in construction. Mechanical automatic cement slurry spraying is used more frequently, and the accompanying cement slurry spraying devices are also emerging in endlessly. However, there is a problem with the mechanical cement slurry spraying device: due to the stickiness of the cement slurry, the spray holes are easy to block. When the nozzles (spray holes) are bl...
