自上料攪拌車可裝運(yùn)由攪拌廠站生產(chǎn)的混凝土或按配比混合的骨料砂、石子、水泥和水，在運(yùn)輸過程中，不斷對(duì)濕料慢慢攪拌，防止混凝土在運(yùn)輸過程中初凝和離析。但是，混凝土從生產(chǎn)到澆注的時(shí)間一般不能超過1.5h，自上料攪拌車多少錢，以免混凝土凝結(jié)。
The self loading mixer can transport the concrete produced by the mixing plant or the aggregate sand, stone, cement and water mixed according to the proportion. During the transportation, the wet materials are continuously mixed slowly to prevent the initial setting and segregation of the concrete during the transportation. However, the time from production to pouring of concrete should not exceed 1.5h. How much is the self loading mixer to avoid concrete setting.
所以，在更遠(yuǎn)距離運(yùn)輸?shù)那闆r下，需采用干料和半干料攪拌運(yùn)輸車來運(yùn)送。干料式攪拌運(yùn)輸車可按配比將干狀骨料和水泥直接裝入該車的攪拌筒內(nèi)，在運(yùn)輸過程中筒內(nèi)的干料進(jìn)行攪拌，當(dāng)車輛將要到達(dá)施工場地或在施工場地再加水完成混凝土的攪拌。
Therefore, in the case of longer distance transportation, the dry and semi dry material mixing truck should be used for transportation. The dry material mixer truck can directly load the dry aggregate and cement into the mixing drum of the truck according to the proportion. During the transportation, the dry material in the drum is mixed. When the truck is about to arrive at the construction site or in the construction site, water is added to complete the concrete mixing.
半干料式攪拌運(yùn)輸車所裝運(yùn)的混凝土中的骨料和水泥也是按配比配制的，并含有一定的水，自上料攪拌車報(bào)價(jià)，但水的含量達(dá)不到澆注要求，需在車輛將要達(dá)到施工場地或在施工場地加水?dāng)嚢琛?/div>
The aggregate and cement in the concrete transported by the semi dry material mixing truck are also prepared according to the proportion, and contain a certain amount of water. The price is quoted from the feeding mixing truck, but the water content does not meet the pouring requirements, so it is necessary to add water to the construction site or when the vehicle is about to reach the construction site.
攪拌車手剎系統(tǒng)都是作用在后輪上的。而因?yàn)楹筝喼苿?dòng)器的形式不同，手剎又有兩種工作環(huán)境：在安裝鼓式制動(dòng)器的后輪上，由于鼓式制動(dòng)器本身就可以兼作駐車制動(dòng)器。
The hand brake system of the mixer truck acts on the rear wheel. Because of the different forms of the rear wheel brake, the handbrake has two working environments: on the rear wheel with drum brake, the drum brake itself can also be used as the parking brake.
因此在駐車時(shí)剎車鼓內(nèi)的蹄片和摩擦片相接合，這樣就可以產(chǎn)生制動(dòng)力。而在安裝碟式制動(dòng)器的后輪上，由于沒有剎車鼓，因此則必須在剎車碟的中心部位安裝額外的駐車剎車鼓來使手剎完成制動(dòng)工作。
Therefore, when parking, the shoes and friction plates in the brake drum are engaged, which can generate braking force. In the rear wheel with disc brake, there is no brake drum, so it is necessary to install additional parking brake drum in the center of the brake disc to complete the brake work.
在行使過程中不可避免會(huì)遇到特殊情況而采取緊急制動(dòng)加上攪拌筒本身有一定的傾角，所以副車架前臺(tái)承受的載荷相對(duì)來說要大得多，而這一部分載荷主要加在聯(lián)接減速機(jī)與前支撐座的六個(gè)螺栓上。
In the process of running, it is inevitable to encounter special circumstances and take emergency braking. In addition, the mixing drum itself has a certain inclination angle, so the load on the front desk of the subframe is much larger, and this part of the load is mainly added on the six bolts connecting the reducer and the front support seat.
為防止螺栓發(fā)生被剪斷而釀成事故，使螺栓不受到剪切力的影響，確保車輛運(yùn)行中的安全。為滿足攪拌車的填充率，攪拌筒還要滿足一定的傾角要求。減速機(jī)和前臺(tái)支撐架在裝配后已經(jīng)固連為一體，無法對(duì)攪拌筒產(chǎn)生有效的支撐。
In order to prevent the bolt from being sheared and causing accidents, make the bolt not affected by the shear force, and ensure the safety of the vehicle in operation. In order to meet the filling rate of the mixer, the mixing drum should also meet certain inclination requirements. The reducer and the front support frame have been fixed as a whole after assembly, which can not effectively support the mixing drum.
這時(shí)整個(gè)結(jié)構(gòu)就相當(dāng)于一個(gè)懸臂梁。這對(duì)于減速機(jī)來說會(huì)產(chǎn)生很大的扭轉(zhuǎn)力矩。為防止由此給減速機(jī)帶來的危害，支重滾輪攪拌泵送一體機(jī)經(jīng)濟(jì)效益。
At this time, the whole structure is equivalent to a cantilever beam. This will produce a lot of torque for the reducer. In order to prevent the harm to the reducer, the economic benefit of the roller mixing pumping machine is improved.
