Furthermore, one side of the cover plate facing the fixing plate is provided with a convex strip, and a groove which is embedded with the convex strip is arranged in the elbow pipe body.
Through adopting above-mentioned technical scheme, the setting of sand grip and recess for the apron is more stable installs at the return bend originally internally, prevents that the apron from taking place to slide under the impact of concrete.
Furthermore, one side of the fixing plate, which faces the elbow body, is provided with a first sealing groove, the outer surface of the elbow body is provided with a second sealing groove, the second sealing groove forms a sealing cavity with the first sealing groove, and a water stop strip is arranged in the sealing cavity.
Through adopting above-mentioned technical scheme, the gas tightness of carrying the return bend can be guaranteed in the setting of stagnant water strip to avoid the concrete to spill after wearing the damage of apron.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) through the arrangement of the detachable and replaceable cover plate, the cover plate bears the abrasion of concrete in the flowing process of the concrete, so that the service life of the concrete conveying elbow is prolonged;
(2) through the arrangement of the buffer material, the impact force of the concrete on the cover plate can be reduced, so that the service life of the cover plate is prolonged;
(3) through the setting of sealing strip, can guarantee to carry the gas tightness of return bend to avoid the concrete to spill after wearing the damage with the apron.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The utility model provides a concrete conveying elbow, referring to fig. 1 and showing, including return bend body 1, opening 2 has been seted up in the outside of return bend body 1, demountable installation has the apron 3 with return bend body 1 inner wall looks butt on opening 2, installs the fixed plate 4 rather than outer wall looks butt on the outer wall of outer tube body, has seted up locating hole 5 on apron 3 and the fixed plate 4, is connected through bolt 6 and nut 7 in the locating hole 5 between apron 3 and the fixed plate 4.
Further, in order to increase the service life of the cover plate 3, a buffer material 8 is filled between the cover plate 3 and the fixing plate 4. The impact force caused by the concrete on the cover plate 3 can be reduced through the buffer material 8, so that the service life of the cover plate 3 is prolonged.
