Safe operation of small concrete mixer must know, small concrete mixer safe operation daily maintenance mainly has three aspects: ① car body maintenance, including paint, cushion carpet, bumper, skirt, instrument panel, tire, wheel hub, windshield, chassis, etc. ② In car maintenance, including: lubrication system, fuel system, cooling system, brake system, carburetor (injector) maintenance, etc. ③ Car body renovation, including the diagnosis and treatment of deep scratches, multi material bumper repair, wheel hub (cover) hard damage repair, leather, chemical fiber material renovation, engine color renovation, etc.

小型混凝土攪拌車(chē)開(kāi)始工作前，檢查油箱、液壓泵、馬達內是否有足夠的清潔的液壓油，水箱是否灌滿(mǎn)水，各潤滑部位是否有足夠的潤滑油。發(fā)動(dòng)汽車(chē)發(fā)動(dòng)機運轉片刻，向貯氣筒充足氣。把操縱油泵伺服閥的手柄放在位置，此時(shí)攪拌筒處于靜止狀態(tài)。一切正常后，操縱手柄使攪拌筒在低速下正反轉2~3次，檢查液壓傳動(dòng)系統是否正常。

Before the small concrete mixer starts to work, first check whether there is enough clean hydraulic oil in the oil tank, hydraulic pump and madar, whether the water tank is filled with water, and whether there is enough lubricating oil in each lubricating part. Start the car engine, run for a moment, and fill the air reservoir with air. Put the handle of the servo valve of the oil pump in the central position, and the mixing drum is in a static state. After everything is normal, operate the handle to make the mixing drum rotate forward and backward at low speed for 2 ~ 3 times, and check whether the hydraulic transmission system is normal.

小型混凝土攪拌車(chē)把車(chē)開(kāi)到攪拌站加料漏斗下，使車(chē)的進(jìn)料斗口與攪拌站的出料漏斗口對正，防止混凝土流到車(chē)外面造成浪費和污染車(chē)體。攪拌車(chē)操縱手柄，使攪拌筒正轉達10~12r/min，這時(shí)可向攪拌筒進(jìn)料。料裝到公稱(chēng)攪動(dòng)容量時(shí)，操縱手柄，將發(fā)動(dòng)機轉速調為1800r/min時(shí),使攪拌筒的攪動(dòng)轉速為1~3r/min，使發(fā)動(dòng)機轉速為小后，然后在駕駛室鎖住手柄，把車(chē)開(kāi)交貨地點(diǎn)。

The small concrete mixer truck drives the truck under the feeding hopper of the mixing station to align the inlet of the truck with that of the discharge hopper of the mixing station, so as to prevent the concrete from flowing outside the vehicle, causing waste and pollution to the vehicle body. Operate the handle of the mixer truck to make the mixing drum transfer 10 ~ 12R / min, and then the material can be fed to the mixing drum. When the material is loaded to the nominal stirring capacity, control the handle, adjust the engine speed to 1800r / min, make the stirring speed of the mixing cylinder be 1 ~ 3R / min, make the engine speed is the minimum, then lock the handle in the cab and drive the vehicle to the delivery place.

混凝土攪拌車(chē)從進(jìn)料開(kāi)始到卸料完畢允許的時(shí)間為1.5小時(shí)或拌筒旋轉300轉（取其中時(shí)間短者）。車(chē)輛滿(mǎn)載上坡應適當使拌筒旋轉速度加快。車(chē)到交貨地點(diǎn)后，把卸料溜槽和加長(cháng)溜槽轉向需卸料的位置。在操縱車(chē)輛尾部?jì)蓚仁直?，應解開(kāi)駕駛室操縱定位鎖緊板，才能實(shí)現拌筒尾部正反轉操作。然后根據工地要求的速度進(jìn)行卸料。

The maximum time allowed for the concrete mixer truck from the beginning of feeding to the completion of unloading is 1.5 hours or 300 revolutions of mixing drum (whichever is shorter). When the vehicle is loaded uphill, the rotation speed of mixing drum shall be accelerated properly. After the vehicle arrives at the delivery place, turn the unloading chute and lengthened chute to the place where the unloading is required. Before operating the handles on both sides of the tail of the vehicle, the locking plate of the control and positioning of the cab should be untied to realize the forward and reverse operation of the mixing drum tail. Then according to the site requirements of the speed of unloading.
