Feeding and discharging system

小型混凝土搅拌车进出料系统由进料斗、出料斗、主卸料槽、副卸料槽、支架、锁紧架等组成，是搅拌车的重要组成部分，直接影响到进出料的速度和质量。进、出料斗通过支架和副车架的后台支撑架相连。出料斗及主卸料槽内加有衬板，衬板采用高强度细晶粒合金钢，其耐磨能力为Q345A(原16Mn)的1.59倍，大幅度的提高了耐磨性。

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.

主卸料槽能使混凝土朝所要求的方向卸出，副卸料槽起延长主卸料槽的长度的作用。在副卸料槽接长时，拉下副卸料槽上的锁柄，锁紧。锁紧架在卸料槽不工作时，将主卸料槽锁定。

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. 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.

卸料槽不工作时，将其向里一推，便会自动锁定，掀下锁柄，即可将卸料槽拉出。卸料槽控制杆起回转支撑卸料槽，及调节卸料槽槽口的上下位移的作用，采用螺旋丝杠传动，定位准确，联接可靠，移动时轻巧省力。锁紧杆将转任意一位置的卸料槽锁定。掀下手柄，即可解除锁定。

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. 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.

●操作系统

Operating system

小型混凝土搅拌车操作系统由控制器、联动轴、软轴及连杆机构组成,主要控制搅拌筒的转速及旋转方向。搅拌车后部两侧各布置一套控制器，左右控制器可以实现联动，控制器上只有一根操纵杆，接出端分别通过连杆机构连接到变量泵上，通过改变泵上控制柄的角度来调节油泵的流量，从而实现控制筒体转动的方向和速度，通过左右移动手柄来控制；该手柄同时还端通过软轴连到发动机的油门上，在需要加大转速时可上下移动来操纵手柄，控制此操纵杆来实现筒体转速的提高。

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.

●液压系统

Hydraulic system

小型混凝土搅拌车液压系统是由包括减速器和变量柱塞泵所组成的闭式回路，且变速箱与液压系统采用同一油路。减速器选用德国ZF或意大利PMP公司生产的混凝土搅拌车专用减速器，柱塞泵、液压马达则选用德国力士乐公司的产品，能提供的输出性能和超长的使用寿命。整个系统所使用的润滑油型号为SAE15W-40，油品等级不低于下列标准：-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.

●电器系统

Electrical system

小型混凝土搅拌车搅拌车的电器系统由三部分组成：冷却风扇控制部分和后示廓灯部分。冷却风扇控制部分：冷却风扇的起停由温度开关自动控制，温度高于65℃时风扇启动，低于60℃时风扇停止。温度开关位于冷却器上，继电器与保险片在蓄电池旁电源继电器盒内。后示廓灯部分：后示廓灯用于夜间表示车后部轮廓大小，与后牌照灯同时点亮与熄灭。

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.
