● feeding and discharging system
小型混凝土攪拌車進出料係統由進料鬥、出料鬥、主卸料槽、副卸料槽、支架、鎖緊架等組成，是攪拌車的重要組成部分，直接影響到進出料的速度和質量。進、出料鬥通過支架和副車架的後台支撐架相連。出料鬥及主卸料槽內加有襯板，襯板采用高強度細晶粒合金鋼，其耐磨能力為Q345A(原16Mn)的1.59倍，大幅度的提高了耐磨性。主卸料槽能使混凝土朝所要求的方向卸出，副卸料槽起延長主卸料槽的長度的作用。
The feeding and discharging system of small concrete mixer is composed of feeding hopper, discharging hopper, main discharging tank, auxiliary discharging tank, support and locking frame. It is an important part of mixer and directly affects the speed and quality of feeding and discharging. The feeding hopper and the discharging hopper are connected with the backstage support frame of the subframe through a bracket. The liner is made of high strength fine grain alloy steel. Its wear resistance is 1.59 times of Q345A (original 16Mn), which greatly improves the wear resistance. The main discharge chute can discharge the concrete in the required direction, and the auxiliary discharge chute can extend the length of the main discharge chute.
在副卸料槽接長時，拉下副卸料槽上的鎖柄，鎖緊。鎖緊架在卸料槽不工作時，將主卸料槽鎖定。卸料槽不工作時，將其向裏一推，便會自動鎖定，掀下鎖柄，即可將卸料槽拉出。
When the auxiliary discharge chute is lengthened, pull down the lock handle on the auxiliary discharge chute to lock. The locking frame locks the main discharge chute when the discharge chute is not working. When the discharge chute is not working, push it inward, it will automatically lock, lift the lock handle, and then the discharge chute can be pulled out.
卸料槽控製杆起回轉支撐卸料槽，及調節卸料槽槽口的上下位移的作用，采用螺旋絲杠傳動，定位準確，聯接可靠，移動時輕巧省力。鎖緊杆將轉至任意一位置的卸料槽鎖定。掀下手柄，即可解除鎖定。
The control rod of the discharge chute has the function of supporting the discharge chute and adjusting the up and down displacement of the discharge chute notch. It is driven by spiral screw, with accurate positioning, reliable connection and light and labor-saving movement. The locking rod locks the discharge chute which is turned to any position. Lift the handle to release the lock.
●操作係統
Operating system
小型混凝土攪拌車操作係統由控製器、聯動軸、軟軸及連杆機構組成,主要控製攪拌筒的轉速及旋轉方向。攪拌車後部兩側各布置一套控製器，左右控製器可以實現聯動，控製器上隻有一根操縱杆，接出端分別通過連杆機構連接到變量泵上，通過改變泵上控製柄的角度來調節油泵的流量，從而實現控製筒體轉動的方向和速度，通過左右移動手柄來控製；該手柄同時還端通過軟軸連到發動機的油門上，在需要加大轉速時可上下移動來操縱手柄，控製此操縱杆來實現筒體轉速的提高。
The operating system of small concrete mixer is composed of controller, linkage shaft, flexible shaft and linkage mechanism, which mainly controls the rotation speed and direction of mixing drum. A set of controllers are arranged on both sides of the rear of the mixer truck, and the left and right controllers can realize linkage. There is only one control rod on the controller, and the connecting end is connected to the variable displacement pump through the connecting rod mechanism. The flow of the oil pump is adjusted by changing the angle of the control handle on the pump, so as to control the direction and speed of the cylinder rotation, which is controlled by moving the handle left and right; At the same time, the handle is connected to the throttle of the engine through the flexible shaft, and can be moved up and down to control the handle when the speed needs to be increased, so as to control the control lever to improve the cylinder speed.
●液壓係統
Hydraulic system
小型混凝土攪拌車液壓係統是由包括減速器和變量柱塞泵所組成的閉式回路，且變速箱與液壓係統采用同一油路。減速器選用德國ZF或意大利PMP公司生產的混凝土攪拌車專用減速器，柱塞泵、液壓馬達則選用德國力士樂公司的產品，能提供卓越的輸出性能和超長的使用壽命。整個係統所使用的潤滑油型號為SAE15W-40，油品等級不低於下列標準：-MIL-L-46152C/-D/-E。
The hydraulic system of small concrete mixer is a closed circuit composed of reducer and variable piston pump, and the transmission and hydraulic system use the same oil circuit. The reducer is a special reducer for concrete mixer produced by ZF of Germany or PMP of Italy, while the plunger pump and hydraulic motor are made by Rexroth of Germany, which can provide excellent output performance and super long service life. The model of lubricating oil used in the whole system is SAE15W-40, and the oil grade is not lower than the following standards: - mil-l-46152c / - D / - E.
●電器係統
Electrical system
小型混凝土攪拌車攪拌車的電器係統由三部分組成：冷卻風扇控製部分和後示廓燈部分。冷卻風扇控製部分：冷卻風扇的起停由溫度開關自動控製，溫度高於65℃時風扇啟動，低於60℃時風扇停止。溫度開關位於冷卻器上，繼電器與保險片在蓄電池旁電源繼電器盒內。後示廓燈部分：後示廓燈用於夜間表示車後部輪廓大小，與後牌照燈同時點亮與熄滅。
The electric system of small concrete mixer consists of three parts: cooling fan control part and rear position indicator part. Cooling fan control part: the start and stop of the cooling fan is automatically controlled by the temperature switch. The fan starts when the temperature is higher than 65 ℃, and stops when the temperature is lower than 60 ℃. The temperature switch is located on the cooler, and the relay and fuse are in the power relay box beside the battery. Rear clearance lamp part: the rear clearance lamp is used to indicate the size of the rear contour of the vehicle at night, and is on and off at the same time as the rear license plate lamp.
