Abstract
The invention discloses a sealing device for a truck-mixed concrete stirring cylinder, belonging to a sealing device. The sealing device for the truck-mixed concrete stirring cylinder structurally comprises an observation door, a middle connection door and a discharging door; the upper part of the middle connection door is hinged with the observation door, and the lower part of the middle connection door is hinged with the discharging door; the middle connection door is connected with the feeding hopper through a round cylinder; a semicircular hole is formed in the upper part of the discharging hopper; the round cylinder is located at the upper part of the bottommost end of the semicircular hole; a feeding opening of the feeding hopper extends into a feeding cone of the stirring cylinder along the round cylinder; a water pipe is arranged at the inner side of the round cylinder; one end of the water pipe is plugged; two rows of staggered spraying holes with a diameter of 4 mm are arranged on the pipe wall; and the other end of the water pipe is connected with an upper water hose by extending out from the round cylinder. Compared with the prior art, with the adoption of the sealing device for the truck-mixed concrete stirring cylinder provided by the invention, the dust raising problem in a stirring process of the truck-mixed concrete stirring cylinder can be effectively controlled, so that the sealing device has good popularization and application values.
Description
Technical field
The present invention relates to a kind of sealing device, especially a kind of transit-mix concrete mixing drum sealing device.
Background technology
The thereupon development of society, environmental problem more and more becomes the topic that people pay close attention to.Therefore, in machinery manufacturing industry, how to make effectively the avoid environmental pollution of product in construction and manufacture process also gradually become the top-priority problem of wanting in the design process.
The transit-mix concrete agitator truck not only has the transportation function of traditional agitator truck, and have the mixing drum that concrete-agitating function-the be transit-mix concrete that the siccative station prepares can directly drop into the transit-mix concrete agitator truck, stirred by mixing drum.But because transit-mix concrete produces dust easily in whipping process, common mixing drum can't effectively be controlled the dust that produces, and damage ratio is more serious.
At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of transit-mix concrete mixing drum sealing device for above-mentioned deficiency of the prior art, and this transit-mix concrete mixing drum sealing device has the airborne dust problem characteristics that occur in effective control transit-mix concrete mixing drum whipping process.
The technical solution adopted for the present invention to solve the technical problems is: it comprises observes door, middle connection door and Dump gate, the top of connection door connects with the observation door hinge in the middle of described, bottom and Dump gate are hinged, link to each other by circular cylinder body between connection door and the feed hopper in the middle of described, the top of described Dump gate has a semi-circular hole, described circular cylinder body is positioned at the top of semi-circular hole lowermost end, the discharging opening of feed hopper stretches in the mixing drum charging cone along circular cylinder body, described circular cylinder body inboard is provided with water pipe, one end of described water pipe is blocked, arranging the staggered diameter of two rows on the tube wall is the spray apertures of 4mm, and the other end stretches out circular cylinder body and is connected with upper glue pipe.
Sealing device is connected with bolt with feed hopper by middle connection door, is provided with support bar between described observation door and the circular cylinder body.
The outer lower portion of described Dump gate is provided with an oil cylinder, and the other end of described oil cylinder links to each other with feed hopper.
Transit-mix concrete mixing drum sealing device of the present invention is compared with existing technology, have following outstanding beneficial effect: control in full force and effect the airborne dust that in the process of trucd mixer mixed concrete, produces of transit-mix concrete mixing drum, reduced the pollution to environment, also increased simultaneously the dischargeable capacity of mixing drum, the characteristics such as easy to use.

The specific embodiment
Explain below doing with reference to Figure of description 1, accompanying drawing 2 and 3 pairs of transit-mix concrete mixing drum sealing devices of the present invention of accompanying drawing.
Transit-mix concrete mixing drum sealing device of the present invention, its structure comprises observes door 1, middle connection door 2 and Dump gate 3, the top of connection door 2 is hinged by a connecting axle with observation door 1 in the middle of described, observing door 1 can rotate around connecting axle, bottom and Dump gate 3 are hinged by a connecting axle, Dump gate 3 can be rotated around connecting axle, link to each other by circular cylinder body 8 between connection door 2 and the feed hopper 4 in the middle of described, the top of described Dump gate 3 has a semi-circular hole 10, described circular cylinder body 8 is positioned at the top of semi-circular hole 10 lowermost ends, in case Dump gate 3 when opening with middle connection door 2 on circular cylinder body 8 interference, the discharging opening of feed hopper 4 stretches in the mixing drum 9 chargings cone along circular cylinder body 8, described circular cylinder body 8 inboards are provided with water pipe 6, one end of described water pipe 6 is blocked, arranging the staggered diameter of two rows on the tube wall is the spray apertures of 4mm, and the other end stretches out circular cylinder body 8 and is connected with upper glue pipe.Be provided with water pipe 6, after stirring is finished, water pipe 6 linked to each other with water tank, the helical blade in the mixing drum 9 is cleaned.
Sealing device is connected with feed hopper 4 usefulness bolts by middle connection door 2, is provided with support bar 7 between described observation door 1 and the circular cylinder body 8.
The outer lower portion of described Dump gate 3 is provided with an oil cylinder 5, is used for controlling the switching of Dump gate 3, and the other end of described oil cylinder 5 links to each other with feed hopper 4.
Sealing device and feed hopper 4 fix, be blocked in the charging aperture place of mixing drum 9, when the material in the mixing drum 9 is stirred, can check by opening observation door 1, when not needing to check, by support bar 7 it being observed door 1 supports, when the needs discharging, open Dump gate 3 by oil cylinder 5, material is drawn off, when Dump gate 3 is closed, realize the sealing to mixing drum 9, make the airborne dust that produces in the whipping process can be sealed in mixing drum 9 inside fully, thereby effectively alleviate airborne dust to the pollution of environment; Because mixing drum 9 is sealed, also good inhibitory action can be arranged to the flash that may occur in the concrete-agitating process, has increased the dischargeable capacity of mixing drum.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
