一、用途及特點

I. Purpose and Feature

本機適用于建筑科研和生產(chǎn)部門混凝土試驗室，可攪拌普通混凝土和輕質(zhì)混凝土。本機結(jié)構(gòu)簡單，參入防凍劑混合勻稱攪拌時間短，殘留量少，質(zhì)量好，操作方便，能保證每盤混凝土配合比的準確，清洗方便，是一種新型試驗室用攪拌設(shè)備。

This machine is applicable for concrete laboratories of architectural research and production sectors and is used to mix ordinary concrete and lightweight concrete. This machine with a simple structure features uniform mixing of anti freezing agent, short mixing duration, small residue, high quality and convenient operation and can ensure the correct concrete mix ratio. This machine is a new style easy-to-clean stirring device for laboratory.

三、機器結(jié)構(gòu)簡介

III. Machine Structure

本機是旋轉(zhuǎn)強制式混凝土攪拌機，由傳動系統(tǒng)和手動出料操縱機構(gòu)組成，本機采用蝸輪減速器，機架是本機的支承部件由槽鋼、角鋼和加工焊接而成，攪拌裝置由旋轉(zhuǎn)攪拌器組成，兩者均通過羅栓連接在攪拌裝置上固定板上，旋轉(zhuǎn)攪拌器由滾動軸承和旋轉(zhuǎn)攪拌葉片等組成，各攪拌葉與攪拌筒壁的間隙，均可進行調(diào)整，整個攪拌裝置通過銷軸固定在機架上，可以翻轉(zhuǎn)該機的攪拌裝置，采用浮選形式。這樣就可以避免攪拌過程中攪拌葉片的卡石子現(xiàn)象。傳動系統(tǒng)由電動機、減速器和連接盤等構(gòu)成，手動出料操縱系統(tǒng)由托盤架和操縱桿組成。

This machine is a forced rotary concrete mixer composed of transmission system and manual discharge control mechanism. It is provided with a worm reducer. As the supporting part of this machine, the frame is fabricated and welded of channel steel and angle steel. Stirring device is composed of rotary stirrers. Both of them are connected to the fixing plate of stirring device through bolts. Rotary stirrer is composed of rolling bearing and stirring blade etc. The clearance between stirring blade and cylinder wall is adjustable. The entire stirring device is fixed to the frame through pin shaft, with which the stirring device can be reversed for floatation. In this way, the gravel blockage at stirring blade that may occur during mixing can be avoided. The transmission system is composed of motor, reducer and connection plate etc. Manual discharge control system is composed of tray rack and control bar.

四、使用保養(yǎng)

IV. Operation and Maintenance

使用前先將機器放置平衡、電機接上地線。

Place the machine at a balanced place and connect the motor to ground wire.

使用前的準備和檢查。

Preparation and inspection before operation

預(yù)先稱好的所有混凝土物料加入筒內(nèi)，然后開動機器干攪拌一分鐘左右，再加入水繼續(xù)進行攪拌。

Put all pre-weighed concrete material into cylinder and turn on the machine for drying mixing of about 1 minute. And then add some water and continue the mixing.

攪拌均勻后，搬動出料手柄，拌好的混凝土物料即可倒出，出料的正轉(zhuǎn)反轉(zhuǎn)均可。

rate on the discharge handle after the even mixing and discharge the properly mixed concrete material. Either forward or reverse is available for discharge.

攪拌機使用后，把攪拌筒和攪拌裝置放到工作位置，在筒內(nèi)倒入適量水，把攪拌裝置和攪拌筒清洗干凈，同時要將機器其它部分的混凝土清洗干凈，以避免殘余混凝土粘接在機器上。

After the operation of mixer, operator shall put the cylinder and stirring device in working position and fill the cylinder with the right amount of water. Wash the stirring device and cylinder while removing the concrete from other parts of the machine so as to prevent the residual concrete sticking to the machine.

攪拌機經(jīng)長期使用后，攪拌葉片和攪拌筒底磨損要使各攪拌葉片與筒底的間隙要增大，當間隙增加到4毫米時要及時調(diào)整。

The clearance between stirring blade and cylinder bottom will increase due to the wear of stirring blade and cylinder bottom during long term of operation. Adjustment shall be performed in case the clearance reaches 4mm.

減速箱的潤滑油是30號機油，使用累計一年后，（則要更換，潤滑油保證在箱內(nèi)上下刻度線之內(nèi)，減速箱頂部輸出軸旁邊）的注油機，每使用三個月注適量潤滑油脂。

30# machine oil shall be used for reduction gearbox and shall be changed when the actual operation time reaches one year. The oil level shall be between upper and lower scale marks inside the tank. Appropriate amount of lubricating grease shall be applied to the oiling device beside the top output shaft of reduction gearbox every three months.

注：使用前必須加入足夠的30#機油，否則會造成機器損壞。

Note: sufficient 30# oil machine shall be added before the operation, or the damage to machine may occur.
