Description

Technical Field

[0001] The invention belongs to the technical field of grouting machines, and more specifically relates to an anti-blocking grouting device. Background Art

[0002] The grouting method is a method of injecting certain curable slurries into cracks or pores in rock foundations to improve their physical and mechanical properties. The purpose of grouting is to prevent seepage, plug leaks, reinforce and correct building deflection. The grouting mechanisms include: filling grouting, penetration grouting, compaction grouting and splitting grouting. Grouting materials include granular slurries and chemical slurries. Granular slurries are mainly cement slurries, and chemical slurries include silicate (water glass) and polymer slurries. Grouting devices are often used in the repair of buildings. When traditional grouting devices are used for too long, the slurry will dry and solidify, which can easily lead to pipe blockage. The device cannot be disassembled for dredging, affecting the work efficiency of personnel and some application scenarios of intermittent grouting.

[0003] Therefore, how to provide an anti-blocking grouting device is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0004] In view of this, the present invention provides an anti-clogging grouting device, which has the advantages that two different slurries can be added simultaneously for mixed construction, and a single slurry can also be used. The device is easy to disassemble and maintain, and the discharge pipe is not easily blocked.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A grouting device for preventing blockage comprises: a mixing barrel, a base, a discharge pipe, a heating wire, a first motor, a stirring rod and a feeding mechanism; the bottom sliding sleeve of the mixing barrel is arranged inside the base, the discharge pipe passes through the base and is threadedly connected to the mixing barrel, and the discharge pipe is communicated with the inside of the mixing barrel, the outside of the discharge pipe is wound with a heating wire, the first motor is installed on the top of the mixing barrel, the output end of the first motor extends into the inside of the mixing barrel and is connected to the stirring rod arranged inside the mixing barrel, and the feeding mechanism is installed on the top of the mixing barrel and is communicated with the inside of the mixing barrel.

[0007] Furthermore, a scraper is installed at one end of the stirring rod, and one side of the scraper abuts against the inner wall of the stirring barrel to clean the slurry remaining on the inner wall of the stirring barrel.

[0008] Furthermore, the feeding mechanism includes: a mixing tube, a feeding tube A, a feeding tube B, a guide rod, a piston and an electric telescopic rod; the mixing tube is installed on the top of the mixing barrel and is connected to the interior of the mixing barrel, the feeding tube A is installed on one side of the mixing tube and is connected to the interior of the mixing tube, the feeding tube B is installed on the other side of the mixing tube and is connected to the interior of the mixing tube, a guide rod is installed at the inner bottom of the mixing tube, a piston is slidably connected to the inner side of the mixing tube, a guide rod hole matching the guide rod is opened on the piston, the guide rod hole is connected to the feeding tube B, an electric telescopic rod is installed on the top of the mixing barrel, and the output end of the electric telescopic rod is connected to one end of the piston.

[0009] Furthermore, a bolt is threadedly connected to one side of the base, an arc-shaped abutment pad is installed at one end of the bolt, and the arc-shaped abutment pad is used to fix the mixing barrel. Multiple groups of bolts and arc-shaped abutment pads are provided and are evenly arranged along the circumference of the base.

[0010] Furthermore, a second motor is installed on the outer side of the discharge pipe, and a rotating shaft is connected to the output end of the second motor. The rotating shaft passes through the discharge pipe and extends into the interior of the discharge pipe. A spiral belt stirring blade is installed on the rotating shaft.

[0011] Furthermore, the bottom of the base is connected to a vehicle plate, and the bottom of the vehicle plate is rotatably connected to a universal wheel.

[0012] The beneficial effects of the present invention are:

[0013] The invention has a simple structure and is easy to use. When only one kind of slurry needs to be added, the piston is pushed by the electric telescopic rod to cut off the passage between the feed pipe B and the guide rod hole, and the slurry to be added is added from the feed pipe A. When two kinds of slurries need to be added, the piston is pushed by the electric telescopic rod to connect the passage between the feed pipe B and the guide rod hole, and the two slurries are added from the feed pipe A and the feed pipe B respectively. First, preliminary mixing is carried out in the mixing tube, and then the slurries are stirred and mixed in the mixing barrel. The scraper can scrape off the slurry attached to the wall of the mixing barrel, thereby reducing the time for cleaning in the later stage. The fully mixed slurry flows out from the discharge pipe. At this time, the rotating shaft is driven by the second motor to drive the spiral belt stirring blade to rotate. On the one hand, the slurry can be continuously stirred, and on the other hand, the slurry can be prevented from adhering to the inner wall of the discharge pipe. At the same time, under the action of the electric heating wire outside the discharge pipe, the slurry can be prevented from being air-dried and solidified to cause blockage. When the device needs to be cleaned, the discharge pipe is rotated to remove it, and the bolt is rotated to separate the arc-shaped abutment pad from the stirring barrel, and the stirring barrel can be removed for cleaning. Therefore, the present invention has the advantages of being able to add two different slurries for mixing construction at the same time, and can also use a single slurry. The device is easy to disassemble and maintain, and the discharge pipe is not easy to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS
