小型自上料混凝土攪拌罐車需要哪些核心部分組成?

攪拌筒和支撐其輔助件構成攪拌裝置。攪拌筒是小型自上料混凝土攪拌罐車比較重要的工作部件,絕大部分采用梨形結構。整個攪拌筒的殼體是一個變截面不對稱的雙錐體,外形似梨。中部直徑較大,兩端對接一對不等長的截頭圓錐,前段錐體較短,端面與一封頭焊接在一起;后段錐體較長,端部開口。
The mixing drum and the supporting auxiliary parts constitute the mixing device. Mixing drum is an important working part of small concrete mixer, most of which are pear shaped structure. The shell of the mixing drum is a variable cross-section asymmetric double cone, which looks like pear. The diameter of the middle part is larger, and the two ends are butted with a pair of unequal length truncated cones. The front cone is short, and the end face is welded with a head; the back cone is longer and the end is open.
通過攪拌筒的軸線在前端面上安裝著法蘭,后段錐體上有一環形滾道,它焊接在垂直于攪拌筒軸線的平面圓周上。整個攪拌筒通過轉軸和環形滾道,傾斜臥置在固定于副車架上的調心軸承和一對支承托輪所組成的三點支承結構上,所以攪拌筒能平穩地繞其軸線轉動。攪拌筒的驅動動力來自于液壓馬達對轉軸的驅動。
A flange is installed on the front end face through the central axis of the mixing drum, and there is an annular raceway on the back cone, which is welded on the plane circumference perpendicular to the axis of the mixing drum. Through the central shaft and annular raceway, the whole mixing drum is inclined and lying on the three-point supporting structure composed of the self-aligning bearing fixed on the subframe and a pair of supporting rollers, so the mixing drum can rotate smoothly around its axis. The driving power of mixing drum comes from the drive of hydraulic motor to the central shaft.
自上料混凝土攪拌罐車
攪拌筒從筒口到筒內,沿內壁對稱地焊接著2條帶狀的螺旋葉片,當小型自上料混凝土攪拌罐車攪拌筒轉動時兩條螺旋葉片被帶動,作圍繞攪拌筒軸線的螺旋運動,這是攪拌筒對混凝土進行攪拌或卸料的基本裝置。攪拌筒內還裝有為提高攪拌效率的攪拌板和擴展翅。
Two ribbon spiral blades are symmetrically welded along the inner wall of the mixing drum from the mouth to the inner wall. When the mixing drum of a small concrete mixer truck rotates, the two spiral blades are driven to make a spiral movement around the axis of the mixing drum. This is the basic device for mixing or discharging concrete by the mixing drum. The mixing drum is also equipped with a mixing plate and a spreading wing to improve the mixing efficiency.
在攪拌筒筒口處,沿2條螺旋葉片內邊緣焊接著一個進料小錐,它將筒口以同心圓的形式分割為內外2部分,部分為進料口,混凝土由此裝入攪拌筒內;進料小錐與筒壁形成的環形空間為出料口,卸料時,混凝土在葉片反向螺旋運動的推力下,從此流出。
A feeding cone is welded along the inner edge of the two spiral blades at the opening of the mixing drum. It divides the cylinder mouth into two parts in the form of concentric circles, and the central part is the feeding port, so the concrete is put into the mixing drum; the annular space formed by the feeding cone and the cylinder wall is the discharge port. When discharging, the concrete flows out under the thrust of the reverse spiral movement of the blade.
由上可見螺旋葉片的作用非常重要,小型自上料混凝土攪拌罐車工作過程中受到沖擊力和磨損比較嚴重,破損會使混凝土攪拌的不均勻。另外,螺旋葉片的角度設計若不合理,也有可能使混凝土發生離析現象。
It can be seen from the above that the role of spiral blades is very important. The impact force and wear of small concrete mixer truck are relatively serious during the working process, and the damage will make the concrete mixing uneven. In addition, if the angle design of spiral blade is not reasonable, it may cause concrete segregation.
