Small overheating-resistant concrete stirrer

Abstract

The invention discloses a small overheating-resistant concrete stirrer. The concrete stirrer comprises a stirring barrel, a water inlet pipe, pressure nozzles, a frame, a round cover body, a stirring shaft, a motor, and an anti-overheating protective sleeve. The anti-overheating protective sleeve is sleeved on the exterior of the motor and comprises a sleeve body and a sleeve cover; an anti-overheating interlayer, which is composed of condenser pipes, is arranged on the sleeve body, the sleeve cover is provided with an exhaust fan; the water inlet pipe is embedded in the inner wall of the stirring barrel along the peripheral direction of the upper part of the stirring barrel, pressure nozzles are arranged on the water inlet pipe at intervals; the stirring shaft comprises a main shaft and multiple auxiliary shafts, threads are arranged on the stirring shaft, the main shaft is vertically arranged in the stirring barrel, multiple auxiliary shafts are vertically fixed and arranged on the main shaft in pairs, and the lengths of the auxiliary shafts increase and then decrease from top to bottom. The provided stirrer can prevent motor from getting overheated and has the advantages of long continuous using time, high stirring efficiency, easy maintenance and washing, and long service life.

Description

technical field [0001] The invention relates to a mixer. More specifically, the present invention relates to a small overheating-proof concrete mixer. Background technique [0002] Concrete mixer is a machine that mixes cement, sand aggregate and water to make concrete mixture. It is a special equipment in industrial production and civil construction projects such as water conservancy, bridges, and highways. With the vigorous development of highway traffic construction and civil construction, concrete mixers have developed rapidly, and with the continuous improvement of construction quality and operating efficiency, higher requirements have been put forward for mixing equipment. [0003] At present, commercial concrete on the market is mostly made by mixing with large-scale mixers. Due to the limitation of equipment cost, processing site and transportation conditions, large-scale concrete mixers are not suitable for small and medium-scale buildings and areas with backward t...

Problems solved by technology

[0003] At present, commercial concrete on the market is mostly made by mixing with large-scale mixers. Due to the limitation of equipment cost, processing site and transportation conditions, large-scale concrete mixers are not suitable for small and medium-sized buildings and areas with backward transportation conditions, while small-scale mixers have uneven mixing of materials. , Low strength, low working efficiency, loud noise when in use, motor can not work continuously at high temperature, easy to produce overheating protection and many other problems
