Description
Technical Field
The invention relates to the technical field of commercial concrete equipment, in particular to a concrete nozzle.
Background
Concrete is one of the widely used materials in civil engineering, and is made up of cementing material, aggregate (also called aggregate) and water through proportioning, stirring, vibrating, shaping and curing under a certain condition. The steel has the advantages of high compressive strength, good durability and the like, and can be used in large quantities. In the construction process, concrete is mainly sprayed by a concrete spraying pump, and in anchor-spraying support operation of tunnels, mine roadways and the like, the inner wall of a used concrete nozzle is a smooth surface (a cylindrical surface or a conical surface), and materials are difficult to obtain uniformly mixed concrete slurry in a smooth inner cavity of the nozzle, so that the rebound rate of the sprayed materials in the anchor-spraying support operation of the spraying pump is very high, and a large amount of dust can be generated. In addition, in the process of high-speed concrete spraying, the pressure and the friction force borne by the nozzle are large, the nozzle is abraded due to impact and friction, and the service life is short.
Therefore, in order to ensure that materials such as cement, sand, stones and the like can be uniformly mixed at a position close to the nozzle through the transmission pipeline under the action of the jet pump and promote the hydration degree of concrete, the concrete nozzle carries out anti-abrasion treatment on the easily damaged part in the using process, the rebound rate and the dust concentration are reduced when the concrete is sprayed, and the concrete nozzle is necessary to carry out optimization design.
Disclosure of Invention
The present invention has been made to overcome the above problems occurring in the prior art, and an object of the present invention is to provide a concrete nozzle. In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:
the utility model provides a concrete nozzle, including the nozzle shell, wear-resistant layer, the helix is protruding, the stirring driver, the churn, the puddler, the dust fall pin, set up wear-resistant layer at the feeding portion inner wall, the feeding portion inner wall sets up the churn, the stirring driver sets up on the inner wall of feeding portion, the churn both ends are passed through the stirring driver and are linked to each other with the feeding portion inner wall, evenly crisscross being provided with the puddler on the churn, it is protruding to set up the helix on ejection of compact portion inner wall, set up dust fall pin in ejection of compact portion tail end both sides.
Preferably, the abrasion resistant layer is removable.
Preferably, the range of the rising angle of the spiral line is 45-50 degrees.
Preferably, the included angle between the stirring rod and the horizontal direction is 45-60 degrees.
Preferably, the end of the stirring rod is a sphere.
The invention has the beneficial effects that: the wear-resistant layer on the inner wall of the feeding part of the nozzle is made of high-wear-resistant metal or non-metal materials, so that the service life of the concrete nozzle can be greatly prolonged, the cost is reduced, and the concrete nozzle can be detached when being worn seriously. The churn of feeding portion inner wall makes the material carry out intensive mixing, and the protruding cooperation of helix on the inner wall of ejection of compact portion has promoted the hydration degree of concrete, and ejection of compact portion tail end both sides dust fall shelves pole carries out effectual effect that blocks to the dust that produces, has reduced rebound rate and dust concentration for concrete intensity can be strengthened.

Preferably, the wear-resistant layer (2) can be detached and replaced when worn, so that the service life of the nozzle is prolonged, and the space of the feeding part can be increased after detachment to prevent pipe blockage.
Preferably, the lead angle of the spiral line protrusion (3) ranges from 45 degrees to 50 degrees, and the material is in a rotating advancing state, so that the material can be further uniformly stirred.
Preferably, the included angle between the stirring rods (6) and the horizontal direction is 45-60 degrees, and the stirring rods are uniformly arranged in a staggered manner to fully stir the materials.
Preferably, the end part of the stirring rod (6) is a sphere, so that the stirring of the materials is further enhanced.
During the use, the material is advanced to be gone into feed portion, and stirring driver (4) drive churn (5) rotate, evenly crisscross puddler (6) of being provided with on churn (5) for the concrete obtains the stirring effect. Spiral line protrusions (3) are arranged on the inner wall of the discharging part, and materials perform spiral motion to promote the hydration degree of concrete. The dust fall blocking rod (7) can play a certain blocking role on partial dust in concrete.
