Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixer trucks, and particularly to a discharging mechanism of a concrete mixer truck. Background Technique

[0002] A concrete mixer truck is a very common construction vehicle. The concrete mixer truck is equipped with a concrete mixing tank, which can rotate during driving and parking, and can rotate forward and backward. Therefore, it can mix the concrete during the transportation process to prevent coagulation. The discharging mechanism of the concrete mixer truck is located at the tail. The concrete inside is driven by the reverse rotation of the mixing tank to move towards the tail of the mixing tank, and the concrete is discharged outward through the discharging hopper and the chute below it.

[0003] There are usually three construction methods for the concrete discharged by the concrete mixer truck. One is to discharge it into the feeding port of a concrete pump truck, another is to directly discharge it to the construction location, and the third is to discharge it to a transfer trolley or a transfer hopper. The first and the third discharging methods are equivalent to transferring the concrete, so the chute does not need to swing and can directly discharge the material; the second method is equivalent to directly discharging the concrete instead of transferring it, and the discharged concrete is then spread out by the users.

[0004] The above-mentioned second concrete discharging method is very necessary and is required in many construction sites. During construction, in order to reduce unnecessary accumulation of concrete and reduce the workload of spreading the concrete, when discharging the concrete, one or two workers are needed to swing the chute left and right to maximize the spreading of the discharged concrete at the discharging position. Due to reasons such as the friction of the chute swing, its own gravity and the gravity of the concrete, the operation of continuously swinging the chute has a relatively high labor intensity and wastes labor resources. In view of the above deficiencies, a new discharging mechanism of a concrete mixer truck is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the utility model provides a discharging mechanism of a concrete mixer truck, which is used to solve the problems of high labor intensity and waste of labor resources existing in the prior art when manually swinging the chute left and right to discharge the concrete.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A discharging mechanism of a concrete mixer truck includes a discharging hopper and a chute arranged at the tail of the concrete mixer truck, and a connecting seat fixed to the tail of the concrete mixer truck. The chute is located between the discharging hopper and the connecting seat. A rotating shaft is vertically rotatably connected in the connecting seat. The upper end of the rotating shaft is connected to the bottom of the chute, and a support member is arranged between the lower end of the rotating shaft and the bottom of the chute.

[0008] A drive motor and a worm are installed inside the connecting seat. The drive motor is in transmission connection with the horizontally arranged worm, and the worm meshes with a worm gear fixedly installed on the surface of the inner rotating shaft of the connecting seat.

[0009] Preferably, handles are fixedly connected to the outer walls on both sides of the chute near the lower end.

[0010] Preferably, the top end of the rotating shaft is fixedly connected with a hinge seat, and the rotating shaft is movably hinged to the chute through the hinge seat.

[0011] Preferably, the rotating shaft is directly below the discharge port of the discharge hopper.

[0012] Preferably, the support member includes a positioning sleeve, an internally threaded support pipe rotatably connected thereto inside the positioning sleeve, a support screw threadedly connected thereto inside the internally threaded support pipe, and a crank fixedly connected to one end of the internally threaded support pipe away from the support screw.

[0013] Preferably, the positioning sleeve is movably hinged to the lower end of the rotating shaft, and one end of the support screw away from the crank is movably hinged to the chute.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] By setting a drive motor, a worm, and a worm gear, the drive motor drives the rotating shaft to rotate through the worm and the worm gear, and the rotating shaft drives the chute to swing. By the forward and reverse rotation of the output shaft of the drive motor, the chute can be driven to swing left and right, achieving the effect of replacing manual labor with electric mechanical equipment, and solving the problems of high labor intensity and waste of labor resources when manually swinging the chute left and right to discharge concrete in the prior art.
