Description
Technical Field
The invention relates to the technical field of concrete mixing production, in particular to a multistage concrete mixing device for civil construction.
Background
Civil engineering, i.e., civil engineering, is a general term for scientific techniques for constructing various land engineering facilities. It refers both to the materials, equipment used and the technical activities carried out, such as surveying, designing, construction, maintenance, repair, etc., and to the objects of engineering construction. I.e. various engineering facilities such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, ocean platforms, water supply and drainage and protection projects, which are built on or under the ground, on land and directly or indirectly serve human life, production, military affairs and scientific research. The civil engineering refers to engineering entities for surveying, planning, designing, constructing, installing and maintaining various technical works and the like of newly-built, reconstructed or expanded buildings, structures, related supporting facilities and the like of various projects except house buildings.
Concrete is an indispensable building material in civil engineering works.
The common concrete is artificial stone which is prepared by taking cement as a main cementing material, adding water, sand, stones and chemical additives and mineral admixtures if necessary, mixing the materials according to a proper proportion, uniformly stirring, densely molding, curing and hardening. Concrete is mainly divided into two stages and states: plastic state before setting and hardening, namely fresh concrete or concrete mixture; hardened, i.e. hardened concrete or concrete.
In concrete, sand and stone act as a framework, called aggregate; the cement and water form cement paste, and the cement paste wraps the surface of the aggregate and fills gaps of the aggregate. Before hardening, the cement slurry plays a role in lubrication, so that the mixture is endowed with certain workability, and the construction is convenient. After the cement slurry is hardened, the aggregate is cemented into a solid whole.
The concrete strength grade is divided into a cubic compressive strength standard value, and the Chinese common concrete strength grade is divided into 14 grades: c15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80.
When concrete is prepared, auxiliary materials are usually added in order to improve the quality of finished products, the auxiliary materials are not too high in the whole raw material composition of the concrete, otherwise, adverse effects are easy to occur to cause no increase or decrease of the quality.
However, when concrete is prepared, auxiliary materials are added into a stirring barrel at one time for convenience of drawing, so that the auxiliary materials and aggregate are easily subjected to regional enrichment and are stirred unevenly; in addition, most of the existing stirring devices are fixed, the effect of the concrete raw materials in the barrel and the stirring part is insufficient, and an improvement space exists.
Therefore, the inventor has designed a concrete multistage mixing device for civil engineering to solve the above problems.

in an initial state, the baffle 601 is pressed at the bottom end of the blanking pipe 108 under the action of the class II spring 603 to seal a blanking outlet, so that auxiliary materials for producing concrete, such as a cementing material, can be conveniently put in from a feeding port at the top end of the auxiliary material box 107 and stored;
adding proportioned water and aggregate into the stirring barrel 103, and starting a servo motor to drive the rotating disc 202 to rotate; the push-pull rod 203 pushes and pulls the first sliding sleeve 204 along with the rotation of the rotating disc 202, so that the first sliding sleeve 204 slides on the sliding rod 205 and acts on the stirring barrel 103, the stirring barrel 103 swings left and right around the hinge seat 102, and materials in the stirring barrel 103 swing, so that the materials and the stirring assembly 5 have multi-directional and multi-stage effects;
the stirring barrel 103 drives the fixing plate 106 and the components arranged on the fixing plate 106 to synchronously swing through the fixing rod 105; because the left end of the pull rope 302 is tied on the rope tying ring 301 and is fixed in position, the right end of the pull rope 302 is lifted and placed on the top plate 401 in turn, and the top plate 401 drives the lifting rod 403 to do lifting motion relative to the fixing plate 106 under the guiding of the second sliding sleeve 402 and the second wheel frame 305 in cooperation with the gravity of the components and the action of the first type spring 404;
the connecting base 405 at the bottom end of the lifting rod 403 is lifted and driven to move synchronously;
the connecting base 405 drives the compression bar 604 to synchronously lift through the second plate 605; in the process that the pressing rod 604 moves downwards, the bottom end is gradually contacted with and presses the left end of the baffle 601 downwards, so that the baffle 601 rotates anticlockwise, and the outlet of the blanking pipe 108 is opened to realize discharging; after the pressure rod 604 moves upwards, the left end of the baffle 601 loses pressure, the baffle 601 seals the blanking pipe 108 again under the action of the second-class spring 603 to stop blanking, so that auxiliary materials are intermittently put into the stirring barrel 103, and the condition that the auxiliary materials and aggregate are regionally enriched and unevenly stirred after the auxiliary materials are put into the stirring barrel at one time is avoided. The auxiliary material box 107 and the blanking pipe 108 synchronously swing along with the auxiliary material box, so that the fluidity of the auxiliary material is ensured, and the situation that the blanking of the auxiliary material is not smooth is avoided;
the stirring shaft 501 below the connecting seat 405 drives the stirring rod 509 to move up and down in the stirring barrel 103; the first driven gear 507 is also lifted synchronously and acts with the first rack 508, so that the first driven gear 507 drives the first shaft 506 to rotate in turn; the first bevel gear 504 at the right end of the first shaft 506 rotates immediately, and drives the second bevel gear 503 to drive the stirring shaft 501 to rotate, so that the stirring rod 509 rotates around to generate a stirring effect while ascending and descending in the stirring barrel 103. The stirring component 5 is matched with the swinging of the stirring barrel 103, so that the materials are fully stirred and mixed in the stirring barrel 103, and the concrete meeting the requirements is produced.
It should be noted that the chuck 502 is clamped into the clamping groove of the connecting seat 405 to ensure the connection between the stirring shaft 501 and the connecting seat 405; and the chuck 502 is also rotated in the card slot of the connecting socket 405, thereby eliminating interference.
