A mixer truck top loading and concrete mixer truck

Abstract

A mixer truck top and a concrete mixer truck, the mixer truck top includes a mixing drum, the mixing drum includes a front cone, a middle tube, a rear cone with a closed tail end, a raceway, and blades, and the rear part of the rear cone is covered with a fixing sleeve. There is a material inlet on the upper part of the fixed sleeve, and a discharge port on the lower part of the fixed sleeve. A movable discharge door is installed at the discharge port. A through hole, the front end of the fixed sleeve is in sealing connection with the raceway, and the rear end of the fixing sleeve is in sealing connection with the tail end of the rear cone. The invention has the advantages of compact structure, convenient maintenance, good stability and adaptability to more roads. On the other hand, the present invention also provides a concrete mixer truck comprising the top of the mixer truck.

Description

technical field [0001] The invention relates to a mixer truck top loading and a concrete mixer truck. Background technique [0002] The structure of the concrete mixer truck currently on the market consists of the following parts, such as figure 1 shown. [0003] Chassis (special-purpose second-class chassis) 7', sub-frame 9' (composed of sub-beam 91, front bracket 8, rear bracket 92, long tail 93 and escalator 94), mixing drum 1', feeding and discharging system 6 (composed of feeding Hopper 61, discharge hopper 64, main tank 65), mixing drum 1' is provided with raceway 14', inspection hole 63 and feed small cone 62, there are two problems as follows: [0004] 1. Inlet and discharge system: the tail of the mixing drum is open, the material is fed from the feed hopper to the tail of the mixing drum, and the material is discharged from the tail of the mixing drum to the discharge hopper. Correspondingly, a thick and long tail is set to support the feed and discharge hoppers....

AI Technical Summary

Problems solved by technology

[0004] 1. Inlet and discharge system: the tail of the mixing drum is open, the material is fed from the feed hopper to the tail of the mixing drum, and the material is discharged from the tail of the mixing drum to the discharge hopper. Correspondingly, a thick and long tail is set to support the feed and discharge hoppers. The overall structure Loose, the length of the vehicle is too long

[0005] 2. Mixing drum: In order to facilitate maintenance, inspection holes are set on the drum body, but disassembly and assembly are troublesome, and the sealing gasket must be replaced every time disassembly; at the same time, in order to facilitate feeding and avoid material leakage, a small feeding cone is set inside , and has an inclination angle of 10-15 degrees, the height of the vehicle is relatively high, and the height of the center of gravity is relatively high, and the stability becomes poor

[0006] To sum up, the concrete mixer truck currently on the market has a loose structure, inconvenient maintenance, and poor stability; the length and height of the vehicle are limited on many roads (such as rural roads, bridge holes, etc.), and in many working conditions Descending (such as steep slopes, mines, etc.) is also restricted
