Abstract
The utility model discloses an overflow prevention device for a concrete mixing truck. The overflow prevention device comprises a mixing drum, wherein a feed hopper is arranged at the feed port of the mixing drum, the feed hopper is matched with the feed port of the mixing drum, an overflow baffle connected with the feed hopper is arranged at the inner side of the feed port of the mixing drum, the overflow baffle is matched with the inner side of the feed port, and the end, extending into the mixing drum, of the overflow baffle is provided with a check ring which is protruded toward the wall of the mixing drum. According to the overflow prevention device for the concrete mixing truck adopting the technical scheme, concrete is prevented from entering a clearance between the feed hopper and the feed port of the mixing drum by the overflow baffle, so that the overflow of the concrete is effectively prevented; the concrete is directly flushed into the feed hopper of the mixing truck from a mixing plant, and enters a drum body through the overflow baffle, so that the friction between the concrete and the rubber check ring is greatly reduced, and the service life of the rubber check ring is prolonged.
Description
Technical field
The utility model relates to a kind of concrete mixing and transporting car, relates in particular to the mixing drum overflow-preventing device of concrete mixing and transporting car.
Background technology
Concrete mixing and transporting car is concrete transportation instrument indispensable in capital construction.Concrete mixing and transporting car is very fast in the time starting of shipment pump concrete, or travels when the larger upward slope road surface of gradient, and concrete rocks backward, causes a small amount of concrete excessive by the gap between feed hopper and mixing drum charging aperture.At mixing drum when filling with substance, concrete directly pours trucd mixer feed hopper by mixing plant, and the rubber ring washer by charging aperture enters cylindrical shell, and concrete directly rubs with rubber back-up ring, makes the rubber back-up ring lost of life.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of concrete mixing and transporting car overflow-preventing device that effectively prevents mixing drum flash is provided, and this device can effectively be protected the rubber back-up ring at charging aperture place, improves the service life of rubber back-up ring.
For achieving the above object, the technical scheme of the utility model concrete mixing and transporting car overflow-preventing device is:
A kind of concrete mixing and transporting car overflow-preventing device, comprise mixing drum, charging aperture at mixing drum is provided with feed hopper, feed hopper coordinates with the charging aperture of mixing drum, charging aperture inner side at mixing drum is provided with the flash baffle plate being connected with feed hopper, the inner side of flash baffle plate and charging aperture matches, and the one end that is deep into mixing drum at flash baffle plate is provided with to the back-up ring that stirs barrel projection.Flash baffle plate is inserted into the inner side of mixing drum and arranges to the back-up ring of mixing drum inwall projection, back-up ring has reduced the gap of feed hopper and mixing drum inwall, and can cushion concrete, the concrete overflowing is cushioned in feed hopper, effectively avoided concrete to overflow, flash baffle plate is connected with feed hopper, after when filling with substance concrete impacts flash baffle plate, flows out mixing drum, avoid concrete directly to contact with rubber back-up ring, improved the service life of rubber back-up ring.
The semicircular arc that be shaped as and the charging aperture inner side of described flash baffle plate matches, is provided with in the one end that is deep into mixing drum to the back-up ring that stirs barrel projection.Due to the effect of gravity, the concrete overflowing is to overflow from the lower half circle of charging aperture, so only flash baffle plate need be set in the lower half circle of charging aperture, provides cost savings.
The back-up ring of described projection is the conical surface.The conical surface can better cushion concrete, meets fluid mechanics principle, prevents that concrete from directly clashing into back-up ring and producing splash phenomena.
The utility model compared with prior art, has the following advantages:
Flash baffle plate coordinates with the inner side of the charging aperture of mixing drum and is provided with to the back-up ring that stirs barrel projection, back-up ring has reduced the gap of feed hopper and mixing drum, and will there is the concrete that overflows tendency to cushion in feed hopper, avoided concrete to overflow, during mixing plant dress concrete, concrete directly pours trucd mixer feed hopper by mixing plant, by flash baffle plate, enters cylindrical shell, greatly reduce the friction of concrete and rubber back-up ring, extended the service life of rubber back-up ring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model concrete mixing and transporting car overflow-preventing device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of concrete mixing and transporting car overflow-preventing device, comprise mixing drum 1, charging aperture 11 at mixing drum 1 is provided with feed hopper 2, feed hopper coordinates with the charging aperture of mixing drum, charging aperture 11 inner sides at mixing drum are provided with rubber back-up ring 12, in order to prevent that concrete from overflowing from charging aperture, in charging aperture inner side, be provided with the flash baffle plate 3 being connected with feed hopper 2, flash baffle plate 3 comprises the semicircular arc plate that the inner side with charging aperture matches, and the one end that is deep into mixing drum at flash baffle plate is provided with to the conical surface back-up ring 31 that stirs barrel projection.Flash baffle plate is inserted into the inner side of mixing drum and arranges to the back-up ring of mixing drum inwall projection, back-up ring has reduced the gap of feed hopper and mixing drum inwall, and can cushion concrete, the concrete overflowing is cushioned in feed hopper, effectively avoided concrete to overflow, flash baffle plate is connected with feed hopper, after impacting flash baffle plate, when filling with substance concrete flows into mixing drum, avoided concrete directly to contact with rubber back-up ring, improved the service life of rubber back-up ring, effect due to gravity, the concrete overflowing is to overflow from the lower half circle of charging aperture, so only flash baffle plate need be set in the lower half circle of charging aperture, provide cost savings, the back-up ring of the conical surface can better cushion concrete, meet fluid mechanics principle, prevent that concrete from directly clashing into back-up ring and producing splash phenomena.
