Cement mixture stirrer

Abstract

The invention discloses a cement mixture stirrer. The cement mixture stirrer comprises a stone supply device, a stirring device, a vibrating device, a vibrator connecting device and a hydraulic power device, wherein the stone supply device comprises a plurality of stone funnels which are arranged side by side; a material gate switch is arranged in a discharge hole of each stone funnel; a rotary proportioner which meters in volume is arranged below each stone funnel; the rotary proportioner comprises a roller bracket, wherein the rotary shaft of the roller bracket is arranged below center connecting lines in parallel; each stone funnel is equipped with storage boxes of the same quantity; the storage boxes of each stone funnel are arranged in the peripheral direction around the roller bracket below respective discharge hole; when the roller bracket rotates, the storage boxes of each stone funnel simultaneously reach the position below the discharge hole of the respective stone funnel in sequence; each storage box is in threaded connection with the roller bracket; and the rotary proportioner which meters in volume is arranged above a charge hole of the stirring device. The cement mixture stirrer has the characteristics of stable stone grading, sufficient stirring, a long service life of a vibrating system, stable work of the whole machine, convenient maintenance, and the like.

Description

technical field [0001] The invention relates to a cement mixture mixer. Background technique [0002] Cement-stabilized macadam base is a major pavement structure form of my country's highways. The cement-stabilized macadam mixture is currently constructed using traditional eccentric cement-stabilized macadam vibrating mixing equipment. The traditional eccentric cement-stabilized gravel vibrating mixing equipment has the following disadvantages: (1) The vibration force is small. Since the eccentric block of the eccentric cement-stabilized gravel vibrating mixer is designed and installed in the stirring shaft, it is limited by the structural size of the stirring shaft. The weight of the eccentric block cannot be very large, and the vibration force is small, which will affect the stirring effect. (2) The working noise is high. When the eccentric cement stabilized gravel vibrating mixer is working, the vibrating stirring shaft will impact the casing and the stone under the act...

AI Technical Summary

Problems solved by technology

The traditional eccentric cement-stabilized gravel vibrating mixing equipment has the following disadvantages: (1) The vibration force is small. Since the eccentric block of the eccentric cement-stabilized gravel vibrating mixer is designed and installed in the stirring shaft, it is limited by the structural size of the stirring shaft. The weight of the eccentric block cannot be very large, and the vibration force is small, which will affect the stirring effect

(2) The working noise is high. When the eccentric cement stabilized gravel vibrating mixer is working, the vibrating stirring shaft will impact the casing and the stone under the action of the exciting force. The working noise is very loud, which affects the lives of nearby residents and often causes complaint

(3) The life of the vibrating shaft is short. When the eccentric cement stabilized gravel vibrating mixer is working, the vibrating stirring shaft will impact the casing and the stone under the action of the exciting force, which will easily cause damage to the vibrating shaft and the life of the vibrating shaft is short.

(4) The work of the whole machine is unstable. Due to the short life of the vibration shaft, the vibration shaft must be replaced frequently, resulting in unstable work of the whole machine

(5) Difficult maintenance and high cost. When the eccentric cement stabilized gravel vibrating mixer fails, it is often necessary to replace the vibrating shaft and the vibrating block together. The maintenance cost is high, and the disassembly and assembly is time-consuming, laborious and expensive.
