Ten precautions for safe use of small mixer?

1.在启动搅拌机价钱轨道之前，搅拌机鼓的操作手柄必须处于“停止”位置。

1. Before starting the mixer, the operating handle of the mixer drum must be in the "stop" position.

2.搅拌车启动发动机后，搅拌筒应低速旋转约10分钟，以便在液压油之前，液压油的温度升高20°C以上。

2. After the mixer starts the engine, the mixing drum should rotate at a low speed for about 10 minutes, so that the temperature of the hydraulic oil will rise to 20 ℃ before activating the hydraulic oil ° C or above.

3.如果搅拌机停在室外，则在倒水和碎屑之前将搅拌桶倒置，以确保混凝土桶的质量。

3. If the mixer stops outside, invert the mixing bucket before pouring water and debris to ensure the quality of concrete bucket.

四。在搅拌车运输混凝土时，必须确保滑动铲斗就位，以防止由于松动，行人受伤或影响其他车辆的正常运转而摇摆。..

Four. When concrete is transported by mixer truck, it is necessary to ensure that the sliding bucket is in place to prevent swing due to loosening, pedestrian injury or affecting the normal operation of other vehicles

5.当小型搅拌机装载混合混凝土时，搅拌桶的速度为2-10rpm。在运输过程中，混合桶在平坦道路上的速度保证为2-3rpm。在路面或左右摇摆较大的道路上，请在路面状况改善后停止混合料灌浆并重新开始混合料灌浆。

5. When the small mixer is loading the mixed concrete, the speed of the mixing drum is 2-10rpm. During transportation, the speed of the mixing drum on the flat road is guaranteed to be 2-3rpm. On the road surface or the road with large left and right swing, please stop the mixture grouting and restart the mixture grouting after the road surface condition is improved.

6.小型搅拌机运输混凝土的时间不得超过搅拌站规定的时间。在运输混凝土期间，请勿长时间停止搅拌桶，以防止混凝土分离。

6. The concrete transportation time of small mixer shall not exceed the time specified by mixing station. During the transportation of concrete, do not stop the mixing bucket for a long time to prevent concrete separation.

7.用混凝土填充搅拌车时，在现场的停留时间应在1小时以内，如果加班，现场负责人必须及时做出反应。

7. When filling the mixer truck with concrete, the stay time on site should be less than 1 hour. If working overtime, the person in charge of the site must respond in time.

8.搅拌车运输的混凝土坍落度必须为8厘米或以上。在高温下，从混凝土进入储罐到放出混凝土的时间不应超过2小时，而在雨中则应不超过2.5小时。

8. The slump of concrete transported by mixer truck must be 8 cm or more. Under high temperature, the time from concrete entering the storage tank to concrete releasing should not exceed 2 hours, and in the rain, it should not exceed 2.5 hours.

9.在搅拌车弹出混凝土之前，必须先将其以10-12rpm的速度旋转1分钟，然后再弹出搅拌桶。

9. Before the mixer truck ejects the concrete, it must be rotated at a speed of 10-12rpm for 1 minute, and then ejected from the mixing bucket.

10.小型搅拌机排干车后，立即使用卡车随附的软管冲洗入口，排水料斗和排水槽，以排出车身上的灰尘或残留混凝土。将150-200L的清水倒入搅拌桶中。在此过程中，缓慢旋转混合桶以清洁内壁，在桶壁和混合叶片上不留渣，加水，然后重新填充。

10. Immediately after the small mixer has drained the truck, flush the inlet, drain hopper and drain trough with the hose provided with the truck to remove dust or residual concrete from the truck body. Pour 150-200l clean water into the mixing bucket. In this process, slowly rotate the mixing barrel to clean the inner wall, leave no slag on the barrel wall and mixing blades, add water, and then refill.
