在上一次的搅拌车使用说明之搅拌筒与副车架中，我们了解认识了搅拌车的搅拌筒和副车架，下面就随着小编一起来继续了解认识搅拌车的进出料装置与操纵系统等相关知识。
In the last mixing drum and subframe of the mixing truck instructions, we learned about the mixing drum and subframe of the mixing truck. Now let's continue to understand the relevant knowledge of the feeding and discharging device and control system of the mixing truck with the editor.
进出料装置
Feeding and discharging device
进出料装置由进料斗、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。
The feeding and discharging device is composed of feeding hopper, discharging hopper, main discharge chute, auxiliary discharge chute, support, locking frame, etc. it is an important part of the mixer, which directly affects the speed and quality of feeding and discharging.
进、出料斗通过支架和副车架的后台支撑架相连。进料斗、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2.5～～3倍，大幅度的提高了耐磨性。
The inlet and outlet hoppers are connected with the backstage support frame of the subframe through a bracket. Lining plates are added in the feed hopper, discharge hopper and main discharge chute. The lining plates are made of high-strength fine grain alloy steel, and their wear resistance is 2.5 ~ ~ 3 times that 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。需副卸料槽接长卸料时，只需将副卸料槽装在主卸料槽上即可，非常方便。
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 needs to be extended for discharging, it is only necessary to install the auxiliary discharge chute on the main discharge chute, which is very convenient.
锁紧架装置在卸料槽不工作时，将主卸料槽锁定。
The locking frame device locks the main discharge chute when the discharge chute is not working.
使用方法：卸料槽不工作时，将其向里一推，掀下锁柄，便会自动锁定，向上掀起锁柄，即可将卸料槽拉出。
Usage: when the discharge chute is not working, push it inward, lift the lock handle, and it will automatically lock. Lift the lock handle upward to pull out the discharge chute.
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，采用肩扛式伸缩套筒的方式调节主料槽卸料时的倾角，定位准确，联接可靠，操作方便省力。
The control rod of the discharge chute plays the role of rotating and supporting the discharge chute and adjusting the up and down displacement of the notch of the discharge chute. The shoulder telescopic sleeve is used to adjust the inclination of the main chute during discharge, with accurate positioning, reliable connection, convenient and labor-saving operation.
锁紧杆将转任意一位置的卸料槽锁定。使用方法：掀下手柄，便可锁定，向上掀起锁柄，即可解除锁定。
The locking rod will lock the discharge chute turned to any position. Usage: lift down the handle to lock, and lift up the lock handle to unlock.
操纵系统
control system
小型搅拌车的操作系统由控制器、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。
The operating system of the small mixer consists of a controller, a linkage shaft, a flexible shaft and a connecting rod mechanism, which mainly controls the speed and direction of rotation of the mixing drum. A set of controllers are arranged on both sides of the rear of the mixer. The left and right controllers can realize linkage. There is only one joystick on the controller, and the connecting ends are respectively connected to the variable displacement pump through the connecting rod mechanism.
通过改变泵上控制柄的角度来调节油泵的流量，实现控制筒体转动的方向和速度，可以左右移动来控制;同时还有接出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操纵来控制此操纵杆来实现筒体转速的提高。
Adjust the flow of the oil pump by changing the angle of the control handle on the pump to control the direction and speed of the cylinder rotation, which can be controlled by moving left and right; At the same time, the connecting end is connected to the throttle of the engine through a flexible shaft. When the speed needs to be increased, the control lever can be operated up and down to control the control lever to realize the increase of the barrel speed.
The above is all about the problems and precautions introduced to you today. I hope it can help you. If you want to know more, you can contact us by phone or follow our website http://www.zkzsljbc.com , our staff will contact you in time.
