Embodiment Construction
[0028] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Attached below figure 2 to attach Figure 9 Specific examples of the present invention will be described in detail.
[0029] In order to solve the problem of concrete quality degradation caused by rainwater entering the mixing drum, the embodiment of the present invention proposes a concrete mixer truck, including a chassis 1, a mixing drum 2, a bracket 3 fixed on the chassis 1, and a bracket 3 The material guide device 4 on the top, the material guide device 4 includes a rotating drum 41 and a material guiding drum 42 that is fixedly connected to and communicated with the rotating drum 41. The rotating drum 41 is cylindrical and coaxially sleeved on the The periphery of the inlet section of the mixing drum 2; the material guiding device 4 can rotate relative to the mixing drum 2 and the support 3, and has ...

The invention discloses a concrete mixer truck. The concrete mixer truck comprises a chassis, a mixing drum, a support and a material guiding device, wherein the support is fixedly arranged on the chassis, the material guiding device is arranged on the support and consists of a rotary drum and a material guiding drum fixedly connected and communicated with the rotary drum, and the rotary drum is cylindrical and is coaxially sheathed at the outer periphery of an inlet section of the mixing drum; the material guiding device can rotate relative to the mixing drum and the support and at least has a first preset state and a second preset state; and in the first preset state, the opening of the material guiding drum faces upward, and in the second preset state, the opening of the material guiding drum faces downward. When the concrete mixer truck works in a raining environment, rainwater can be prevented from entering the mixing drum when the opening of the material guiding drum faces downward, thereby further preventing the influence of rainwater to the quality of concrete.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a concrete mixer truck. Background technique [0002] At present, the use of concrete mixer trucks in engineering construction is becoming more and more common. The traditional concrete mixer truck loading and unloading device is an open structure, such as figure 1 As shown, the feeding and discharging device is composed of a feeding hopper 1 and a discharging hopper 2 arranged below the mouth of the mixing drum. A chute for diversion is provided under the feeding hopper 1 of the discharging device, and the end of the chute extends into the mixing drum. . Although the discharge device of this structure is simple in structure and easy to operate, it has the following two problems: [0003] 1. The opening area of this type of feeding and discharging device is large. If it rains during transportation, the rainwater will easily enter the mixing drum. The rainwater flowing in...
