Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a curbstone back concrete pouring device. Background Art

[0002] The concrete backrest of the curb is a reinforcement strip along the back of the curb. The concrete backrest can firmly fix the curb to the road and prevent the curb from shifting and tilting. Because the position of the curb backrest is low and narrow, the curb backrest is hidden behind the curb, which brings many inconveniences to the pouring construction.

[0003] If the existing pouring equipment is used to directly pour the curbstone backrest, since the curbstone backrest is low and narrow, it is easy for the concrete slurry to be spilled to the area outside the backrest during the pouring process, which not only causes a waste of concrete, but also requires manual cleaning later, which is very inconvenient. If manual pouring is used, although it can reduce the waste of concrete, the construction efficiency is low and the cost is high. Therefore, it is necessary to provide a curbstone backrest concrete pouring device that can solve the problems of the existing concrete pouring equipment easily spilling concrete slurry and the low efficiency of manual pouring.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Please see attached Figure 1 To Attachment Figure 3 A device for pouring concrete for a curbstone backrest comprises a pouring chute 1, a baffle 2, a lock 5 and a rotating assembly; the lock 5 is fixedly arranged at one end of the pouring chute 1, so that one end of the pouring chute 1 is detachably connected to the discharge chute of the concrete truck through the lock 5, and the pouring chute 1 is coaxially connected to the discharge chute of the concrete mixer truck, and the other end of the pouring chute 1 is extended to the pouring position of the curbstone backrest; the baffle 2 is rotatably arranged at the other end of the pouring chute 1 through the rotating assembly, and the baffle 2 can be arranged around between the other end of the pouring chute 1 and the pouring position of the curbstone backrest.

[0021] The discharge chute of the concrete mixer truck is relatively high. The pouring chute 1 is coaxially connected with the discharge chute to form an integral chute, which extends the length of the discharge chute and reduces the discharge height of the discharge chute, thereby accurately conveying the concrete slurry to the pouring position of the curbstone backrest, reducing the spillage and waste of concrete and the cleaning work of the spilled concrete.

[0022] The lock buckle 5 facilitates the coaxial docking of the casting chute 1 and the discharging chute, is easy to disassemble and assemble, and can be suitable for connection with different concrete mixer trucks.

[0023] The baffle 2 is used to block between the other end of the casting chute 1 and the curb back casting position.
