Horizontally-arranged self-sealed stirring and transporting vehicle

Abstract

The invention discloses a horizontally-arranged self-sealed stirring and transporting vehicle. A tank body is horizontally arranged on an auxiliary vehicle frame of an automobile chassis. The horizontally-arranged self-sealed stirring and transporting vehicle has the following innovations: a rotary disc bearing connecting flange I is arranged at the combined part of an inlet-outlet material guide pipe; a rotary disc bearing is connected between the rotary disc bearing connecting flange I and a rotary disc bearing foundation; the rotary disc bearing base is then fixed on a rear support; the rotary disc bearing firmly controls the tank body and rotates flexibly; materials are added in or output by utilizing the synchronous running and cooperation of three stirring cages; the liquid level of fluid is lifted by adopting a disc-type spiral lifting stirring cage, so that the loading liquid level exceeds the inlet-outlet material guide pipe and does not leak; the fluid does not overflow in ascending and bumping, and the disc-type spiral lifting stirring cage is insulated and sealed automatically; and the raceway nest support adopts a mode of supporting in the tank body, the tank body supporting intensity is improved, and the total height is not increased. The general design concept provided by the invention focuses on the driving stability, the safety performance, the market survival capability and loading and transportation capability of the stirring and transporting vehicle.

Description

technical field [0001] The invention relates to a new technology for automatically closing and horizontally arranging a stirring transport vehicle in a rotating state, in particular to a stirring transport vehicle in the field of engineering machinery. Background technique [0002] The concrete mixer truck is composed of a car chassis and a special device for concrete mixing. In the early stage, it was a proprietary technology in Germany and Japan, and they are all inclined rotating devices. Now the products of Chinese mixer truck manufacturers have their own technical characteristics, but they are all developed on the basis of the design of these two tanks. Its special mechanism mainly includes drive system, chassis support, tank body, feeding and discharging device, operating mechanism, cleaning system, etc. The working principle is to drive the variable pump of the hydraulic system by the power output of the car chassis through the power take-off device, convert the me...

AI Technical Summary

Problems solved by technology

However, the use of traditional supporting wheels to support the weight and rotation of the tank body also fails to solve the effective fixation of the rear of the tank body, and the driving stability and safety of the vehicle are relatively weak; the rotary sealing mechanism of the mixing drum of the concrete mixer truck is affected by the characteristics of the transported materials. (such as sand, stones and other solid materials, etc.), it is difficult to achieve sealing, Yantai Shenglida Engineering Technology Co., Ltd. has added an automatic sand cleaning device (patent number: 201020502017) of the mixing drum rotary sealing mechanism (patent number: 201220471171) , cleaning devices, etc. to gradually improve

Since one end of the revolving airtight door must be fixed relative to the feed port and does not rotate, but the tank body must rotate, and displacement will occur due to bumps and swings, sand, stones and other solid objects will affect the sealing ring and friction parts during operation. The damage to the steel structure is very serious, and it is very troublesome to maintain. If the seal ring is not repaired and replaced frequently, it will cause leakage, and even the closed door will lose its function due to the beating and swaying of the tank and the deformation or wear of the steel.

More importantly, even if the complete sealing of the inlet and outlet is solved, after the liquid level exceeds the inlet and outlet, the pressure in the tank cannot be discharged due to the air pressure formed by adding materials, and the use of capacity cannot be affected.

[0010] The above defects have restricted the development of concrete mixing transport vehicles, and many problems have concentratedly appeared, which have become the technical bottlenecks of low carrying capacity, poor driving stability and weak safety performance of mixing transport vehicles and cannot be broken through.
