The mixing tank of the full-automatic concrete mixer is a cylinder in the middle and a cone on both sides. The cone angle of the front cone is greater than that of the back cone. The installation angle of the tank is generally 10 ° ~16 °, and the loading volume accounts for about 65% of the total volume. There are generally two right-hand spiral blades in the groove, intersecting 180 °. The blade is Archimedes spiral at the intersection of cylinder and cone, and the rear cone adopts logarithmic spiral blade with equal helix angle. The characteristics of the tank structure of the mixer truck can effectively and fully mix the concrete and discharge the concrete continuously and smoothly at all angles.
There is an operating lever behind the tank of the concrete mixer. The nameplate below the operating lever reads unloading and feeding. Pull the wrench to discharge the material. Generally speaking, the forward feed is delivered to the front of the vehicle and the reverse discharge is delivered to the rear of the vehicle. Below is the fuel valve, which controls the speed of the mixing tank. When it is necessary to accelerate the discharge, the operation is particularly convenient. The mixer is also equipped with a cab operating lever, which can be synchronized with the rear of the mixer. It can also control the forward and reverse rotation of the fuel tank, so that the driver can operate in the cab without getting off.
When operating the can body, first shake the operating lever to the middle position of forward and reverse rotation, and then move the operating lever to the reverse position after the can body is stable. Reverse rotation to forward rotation is the same operation. If we act in a hurry, the gear of the reducer is easily damaged by the inertia of the oil tank. Some of our sites have workers distributing concrete on site. At this time, make it clear to the workers to avoid unnecessary losses.
In addition, there is another problem to know that the tank of the full-automatic concrete mixer rotates. The rotation of the can body is accomplished by the hydraulic drive system on the truck. Usually, the hydraulic pump is driven by the power take-off shaft on the truck to drive the mixing tank. Body rotation. We can often see various traffic accidents of concrete mixer trucks in various reports, which also caused many casualties. These are the main reasons. The entire chassis of the concrete mixer truck is very high, and the driver is in operation. There will be many blind spots, especially when turning.
