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.
小型混凝土搅拌车开始工作前，检查油箱、液压泵、马达内是否有足够的清洁的液压油，水箱是否灌满水，各润滑部位是否有足够的润滑油。发动汽车发动机运转片刻，向贮气筒充足气。把操纵油泵伺服阀的手柄放在位置，此时搅拌筒处于静止状态。一切正常后，操纵手柄使搅拌筒在低速下正反转2~3次，检查液压传动系统是否正常。
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.
小型混凝土搅拌车把车开到搅拌站加料漏斗下，使车的进料斗口与搅拌站的出料漏斗口对正，防止混凝土流到车外面造成浪费和污染车体。搅拌车操纵手柄，使搅拌筒正转达10~12r/min，这时可向搅拌筒进料。料装到公称搅动容量时，操纵手柄，将发动机转速调为1800r/min时,使搅拌筒的搅动转速为1~3r/min，使发动机转速为小后，然后在驾驶室锁住手柄，把车开交货地点。
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.
混凝土搅拌车从进料开始到卸料完毕允许的时间为1.5小时或拌筒旋转300转（取其中时间短者）。车辆满载上坡应适当使拌筒旋转速度加快。车到交货地点后，把卸料溜槽和加长溜槽转向需卸料的位置。在操纵车辆尾部两侧手柄前，应解开驾驶室操纵定位锁紧板，才能实现拌筒尾部正反转操作。然后根据工地要求的速度进行卸料。
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.
