Cement mixing truck with residue removal assisting device

Abstract

A cement mixing truck with a residue removal assisting device is characterized in that the residue removal assisting device is arranged between a mixing drum and a sub-frame of a common cement mixing truck, the residue removal assisting device is composed of bump blocks fixed in the periphery of the mixing drum and a bearer arranged on the sub-frame, and a bump rod and a spring are arranged in the bearer. The bump rod is positioned in the periphery where the bump blocks pass by during the rotation of a drum body when the mixing drum is cleaned, so the mixing drum is controlled to rotate in a discharging direction, the bump rod regularly bumps the drum body under the action of the bump blocks and the spring to make adhesions in the drum shaken and fall, and the adhesions are carried away by flushing water, thereby the device plays a positive role in cleaning assistance; and the bump rod is moved back together with the bearer, and can depart from the bump blocks to recover the normal work state of the cement mixing truck. The cement mixing truck with the residue removal assisting device has the advantages of simple structure, no additional power, good effect and low cost.

Description

Technical field [0001] The invention relates to a cement mixing transport vehicle, in particular to a cement mixing transport vehicle with an auxiliary device for removing residues in a mixing drum. Background technique [0002] At present, cement mixer trucks at home and abroad do not have auxiliary devices for removing the residues in the mixing drum. Generally, the residues in the drum are washed with water. Due to the poor effect, the cement remaining in the drum becomes lumpy and sticky after a long period of time. Attached to the cylinder, it not only reduces the effective volume of the cylinder, but also seriously affects the normal work of loading and unloading cement. The usual method is that the operator hits the outer wall of the mixing drum with a hammer or a hard object to make the residue in the drum fall off. When the residue is seriously bonded or even blocks the auger (deflector) plate in the drum, it will affect the normal loading and unloading. Then open ...

[0002] At present, cement mixer trucks at home and abroad do not have auxiliary devices for removing the residues in the mixing drum. Generally, the residues in the drum are washed with water. Due to the poor effect, the cement remaining in the drum becomes lumpy and sticky after a long period of time. Attached to the cylinder, it not only reduces the effective volume of the cylinder, but also seriously affects the normal work of loading and unloading cement

The usual method is that the operator hits the outer wall of the mixing drum with a hammer or a hard object to make the residue in the drum fall off. When the residue is seriously bonded or even blocks the auger (deflector) plate in the drum, it will affect the normal loading and unloading. When this happens, open the window on the outer wall of the middle section of the cylinder, and manually climb into the cylinder to remove the residue. It can be seen that not only the removal effect is poor, but also the labor intensity for workers is high, and it is very unsafe for workers to enter the cylinder.
