The invention discloses an adjustable limiting device and a concrete mixing truck, belonging to the technical field of engineering machinery and solving the technical problems of smaller working surface and worse limiting effect of the prior art. The adjustable limiting device comprises a limiting block, a check block and a locking structure, wherein a first slope surface is arranged on the limiting block; a second slope surface is arranged on the check block; the second slope surface is pressed on the first slope surface; the second slope surface and the first slope surface can slide relative to each other; the locking structure is arranged on the check block and the limiting block; and the limiting block is detachably and fixedly connected with the check block through the locking structure. The concrete mixing truck comprises a reduction box, a front support and the adjustable limiting device provided by the invention. With the adjustable limiting device and the concrete mixing truck, the limiting area of the reduction box can be improved, and the limiting effect of the reduction box is better.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an adjustable limiting device and a concrete mixer truck provided with the adjustable limiting device. Background technique [0002] Concrete mixer truck is a special vehicle for mixing and transporting concrete, which is composed of a car chassis and a special device for mixing and transporting concrete. [0003] The reducer is an important part of the concrete mixer truck. The reducer is used to reduce the output speed of the motor in the hydraulic system and then transmit it to the mixing drum. The front support is a part of the upper subframe of the concrete mixer truck, and the front support plays an important role in connecting the chassis and the vehicle body. The reducer is installed on the front support, and the limit block is set between the reducer and the front support. The limit block is used to limit the relative displacement between the reducer and t...
