The movement process of automatic feeding mixer mainly includes the movement of engine, hydraulic components (oil system, hydraulic motor, reducer) and mixing drum. Firstly, the engine provides the power source, and then the power is transmitted to the hydraulic motor through rape, and then the reducer decelerates to increase the torque, and finally realizes the rotation of the drum. Because the control terminal is the rotation speed of the mixing drum, and the speed of the mixing drum is determined by the movement of the four parts of the device, the motion analysis process will mainly include the engine, hydraulic components and other parts.

自動上料攪拌車一般使用柴油機作為發(fā)動機，因我過內(nèi)燃機技術(shù)相對國外較為落后，因此在自動上料攪拌車上一般使用國外進口柴油機，目前公司使用的柴油機大多由日本生產(chǎn)，機型包括、、等?，F(xiàn)已系列柴油機進行介紹和分析。

The diesel engine is generally used as the engine of the automatic feeding mixer. As the internal combustion engine technology of our company is relatively backward compared with foreign countries, the imported diesel engine is generally used on the automatic feeding mixer. At present, most of the diesel engines used by the company are produced in Japan, including, and etc. The series of diesel engines have been introduced and analyzed.

系列柴油機是紅直列、活塞式、水冷、增壓才有發(fā)動機。紅徑，行程、虹心距、凈重功率覆蓋范圍為。

Series diesel engine is red in-line, piston type, water-cooled, supercharged engine. Red path, stroke, rainbow center distance, net weight and power coverage are.

系列柴油機通過采用高壓共軌燃油噴射技術(shù)，油耗低、可靠性高，該發(fā)動機上帶有為自動上料攪拌車上裝提供動力的動力輸出口（，大輸出扭矩為大輸出功率

Series diesel engines adopt high-pressure common rail fuel injection technology, with low fuel consumption and high reliability. The engine is equipped with a power output port to provide power for the loading of automatic charging mixer. The large output torque is the high output power

減速機：目前我公司主要采用的是意大利、德國、意大利的減速機，此減速機釆用行星傳動齒輪箱，結(jié)構(gòu)緊湊，傳動效率高，運轉(zhuǎn)安全可靠易于維護保養(yǎng)。

Reducer: at present, our company mainly adopts the reducer of Italy, Germany and Italy. The reducer adopts planetary gear box, with compact structure, high transmission efficiency, safe and reliable operation and easy maintenance.

攪拌耀速度控制：根據(jù)“發(fā)動機轉(zhuǎn)速油菜排量馬達(dá)排量減速機減速比耀體轉(zhuǎn)速，其中馬達(dá)排量、減速機減速比是常數(shù)，罐體轉(zhuǎn)速如果恒定為常數(shù)，則只要發(fā)動機轉(zhuǎn)速油粟排量為常數(shù)即可【。

Speed control of agitator: according to "engine speed, rape displacement, motor displacement, reducer deceleration ratio, the motor displacement and reducer reduction ratio are constant, if the tank speed is constant, then as long as the engine speed and oil displacement are constant [.

電子恒速傳動方案是把液壓粟的控制形式改為電比例控制，液壓錄輸出流量與輸入電流成正比，通過調(diào)節(jié)比例閥的輸入電流，改變液壓粟斜盤角度，從而達(dá)到調(diào)速目的。

The scheme of electronic constant speed transmission is to change the control form of hydraulic pump to electric proportional control. The output flow of hydraulic pressure recorder is proportional to the input current. By adjusting the input current of proportional valve, the angle of hydraulic poppet swash plate can be changed to achieve the purpose of speed regulation.

在一定發(fā)動機速度下，電比例液壓粟開度達(dá)到大，此時如希望攪拌罐的速度再上升則需要提高自動上料攪拌車底盤發(fā)動機速度。

At a certain engine speed, the electric proportional hydraulic poppy degree reaches a large value. At this time, if you want the speed of the mixing tank to rise again, you need to increase the engine speed of the chassis of the automatic feeding mixer.
