Transmission system: the driving mode of the mixing drum is the engine as the power source, and the power is taken by the power take-off at the rear end of the engine. It is transmitted to the variable displacement piston hydraulic pump through the transmission shaft, and then driven to rotate by the reducer through the quantitative plunger oil motor. The feeding and discharging system (loading and discharging mechanism) of the mixing drum is an important device to assist the mixing drum. Control system: it is the control part of the whole mixer. There is an I-shaped slot on the control panel, which is the movable space of the control rod; and the slot in the rear half is provided with a finite position hole to fix the position of the control rod.

該操縱系統(tǒng)通過汽車尾部的左右兩個操縱桿來控制攪拌筒的正、反轉和轉速，從而來完成進出料以及攪拌動作。 供水系統(tǒng)：自上料混凝土攪拌罐車的供水系統(tǒng)主要用來清洗攪拌裝置。該車型的供水系統(tǒng)共有兩種型式，一種是離心水泵供水系統(tǒng)；一種是壓力水箱供水系統(tǒng)，可供用戶選裝。 自上料混凝土攪拌罐車使用注意事項

The control system controls the forward, reverse and rotation speed of the mixing drum through the left and right control levers at the rear of the car, so as to complete the feeding and mixing actions. Water supply system: the water supply system of concrete mixer is mainly used to clean the mixing device. There are two types of water supply system for this vehicle, one is centrifugal pump water supply system, the other is pressure water tank water supply system, which can be selected by users. Precautions for concrete mixer truck

液壓系統(tǒng)壓力應符合使用說明書中的規(guī)定，不得隨意調整。液壓油的油質和油量應符合原定要求。 自上料混凝土攪拌罐車裝料前，應先排凈拌筒內殘存的積水和雜物。在運輸過程中要不停的轉動，以防混凝土離析。混凝土攪拌運輸車到達工地和卸料之前，應先使拌筒全速以14—18轉/分轉動1—2分鐘，然后再進行反轉卸料。

The pressure of the hydraulic system should be in accordance with the provisions of the operation manual, and should not be adjusted at will. The quality and quantity of hydraulic oil should meet the original requirements. Before the concrete mixer truck is loaded, the residual water and sundries in the mixing drum shall be drained. In the process of transportation, keep rotating to prevent concrete segregation. Before the concrete mixer truck arrives at the construction site and unloads, the mixing drum shall be rotated at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading shall be carried out.

反轉之前，應使攪拌筒停穩(wěn)不轉。 環(huán)境溫度高于+25攝氏度，從裝料、運輸、到卸料延續(xù)時間不得超過60分鐘，環(huán)境溫度低于+25攝氏度，上述時間不得超過90分鐘。 冬期施工時，應切實做到：開機前檢查是否結冰；下班時認真排除拌筒內及供水系統(tǒng)內殘存積水，關閉水泵開關，將控制手柄置于“停止”位置。 在施工現(xiàn)場卸料完畢后，應立即用攪拌車隨帶的軟管沖洗進料斗、出料斗、卸料溜槽等處，清除粘附在車身各處的污泥及混凝土。

Before reversing, the mixing drum should be stopped stably. If the ambient temperature is higher than + 25 ℃, the duration from loading, transportation to unloading shall not exceed 60 minutes; if the ambient temperature is lower than + 25 ℃, the above time shall not exceed 90 minutes. During winter construction, it is necessary to check whether there is icing before starting the machine; when off duty, carefully remove the residual water in the mixing drum and water supply system, turn off the water pump switch, and put the control handle at the "stop" position. After unloading at the construction site, the inlet hopper, discharge hopper and discharge chute should be flushed with the hose attached to the mixer to remove the sludge and concrete adhering to the vehicle body.
