The front supporting platform 20, the rear supporting platform 30 and the frame surrounding beam 50 are arranged on the chassis assembly 10 and connected with the chassis assembly 10, and the front supporting platform 20 and the rear supporting platform 30 are respectively supported at the front end and the rear end of the mixing drum 220. The feeding and discharging device 40 is connected with the frame surrounding beam 50 and matched with the feeding and discharging port of the mixing drum 220, and materials are conveyed to the mixing drum 220 through the feeding and discharging device 40.

It should be noted that the front support stand 20 is used to adjust the tilt angle of the mixer drum 220, and after the adjustment is completed, the tilt angle of the mixer drum 220 is fixed, for example, by welding the front stand body 21 and the top plate 22. Similarly, the feeding and discharging device 40 is fixed by bolts after the relative position adjustment with respect to the frame girth 50 is completed. Thus, the mixer truck 200 is formed to have a more firm structure, which contributes to the improvement of the operational stability and operational reliability of the mixer truck 200.

In some embodiments, the mixer truck 200 is embodied as a concrete mixer truck 200.

The loading platform 100 and the mixer truck 200 of the mixer truck provided by the present application are described below in some embodiments.

The mixer trucks 200 are classified into different models according to the loading amount, and the mixer trucks 200 of each model have low part universalization rate and poor interchangeability, resulting in a large number of processing types, high manufacturing cost and difficult later maintenance.

When the mixer trucks 200 with different loading capacity are designed and produced, mixer drums 220 with different lengths and inclination angles need to be used, and mixer trucks 200 with similar structures but different sizes are designed according to different mixer drums 220, so that the mixer trucks 200 with different models have poor part universality. Wherein the inclination angle is also called the tilt angle.

Those skilled in the art will appreciate that the difference in the loading capacity of the mixer truck 200 is mainly caused by the difference in the length and diameter of the mixing drum 220. One embodiment of the present invention provides a flatbed mixer truck 200, which is provided with a loading platform 100 capable of loading mixing drums 220 with different loading capacities, so that the mixing drums 220 with different loading capacities can share the loading platform 100, and the mixer trucks 200 with various loading capacities can share one set of main structure (i.e. the loading platform 100).

Thus, the flatbed mixer truck provided in the present embodiment can carry a series of mixing drums 220 having different lengths of the middle drum and the same size, and is provided with a front support 20 capable of adjusting the inclination angle of the mixing drum 220; the back stage and the feeding and discharging device 40 can adapt to the heights of the rear ends of different mixing drums 220 and the inclination angles of the mixing drums 220; the chassis assembly 10 is provided with a plurality of loading interfaces (including a first loading interface 101 and a second loading interface 102).

Specifically, some embodiments of the present application provide a series of mixing drums 220. As shown in fig. 14, the structure of the mixing drum 220 includes an end cover 2201, a front cone 2202, a middle drum 2203, a rear cone 2204, and a small feeding cone 2205 arranged in sequence. The loading capacity of different mixing drums 220 is realized by changing the length L of the middle drum 2203, the rest structures are completely the same, the mixing blades 2206 only have difference in the blade length of the middle drum 2203, and the mixing drums 220 with different loading capacities can be produced by one set of process, so that the part types and the production difficulty of the mixing drums 220 with different loading capacities are greatly reduced.

Some embodiments of the present application provide an adjustable tilt front support table 20. The inclination angle of the mixing drum 220 is determined by the relative inclination angle between the front main body 21 and the top plate 22, and the top plate 22 and the front main body 21 adopt an adjustable structure, such as an arc surface 211 contacting or a plurality of contact surfaces 221 (planes) selectively contacting, and the like, as shown in fig. 2 to 5, so that the front top plate 22 has a plurality of inclination angle states.

Some embodiments of the present application provide a rear support table 30 that can accommodate different heights and tilt angles. As shown in fig. 15, fig. 15 shows two mixing drums 220 with different loading capacities, wherein the length of the mixing drum 220A in the light color line is L1, the inclination angle is α 1, the length of the mixing drum 220B in the dark color line is L2, and the inclination angle is α 2, and the height (H1, H2) and the inclination angle (β 1, β 2) of the riding wheel 32 of the rear supporting platform 30 also need to be adjusted correspondingly due to the difference in length and inclination angle between the two mixing drums (220A and 220B); the structure of the background main body 31 is unchanged, and adaptation is performed only by changing the local height and the inclination angle of the riding wheel 32, for example, size adaptation is performed by configuring backing plates 34 of the riding wheel 32 with different inclination angles and thicknesses, so that the types of background parts are effectively reduced.

Some embodiments of the present application provide a charging and discharging device 40 that can accommodate different heights and inclinations. Because the length and the inclination angle of the mixing drum 220 are different, the feeding and discharging device 40 also needs to be capable of adapting to feeding and discharging ports of the mixing drum 220 with different heights and inclination angles, and a feeding and discharging fixing mode with certain movable adjusting capacity is designed, for example, longitudinal and transverse groove-shaped fixing hole positions (a first waist hole 401 and a second waist hole 402) are designed, so that the feeding and discharging device 40 has sufficient position adjusting capacity, and has better universality for different mixing drums 220.

Some embodiments of the present application provide a chassis assembly 10 having a plurality of upper mounting attachment interfaces (including a first upper mounting interface 101, a second upper mounting interface 102). The mixing drum 220 with different loading capacity will affect the loading length of the mixer truck 200, and it is necessary to set loading interfaces with different positions, so that by designing a plurality of loading fixing interfaces (including the first loading interface 101 and the second loading interface 102) on the chassis assembly 10 of the mixer truck 200, the relative positions of the front support platform 20 and the rear support platform 30 can be adjusted, and a disc with multiple purposes is realized, as shown in fig. 8.

In some embodiments of the present application, the relative positions of the front support platform 20 and the rear support platform 30 are adjusted by adjusting the overall length of the chassis assembly 10 to accommodate mixing drums 220 of different lengths and inclinations. As shown in fig. 9, an extension 12 is added to the chassis frame 11 to adjust the overall length of the chassis assembly 10.

Thus, the loading platform 100 and the mixer truck 200 of the mixer truck provided by the embodiment of the invention have at least the following beneficial effects: (1) the mixing drums 220 with different loading capacities are planned in a unified mode, so that the part types and the production difficulty of the mixing drums 220 with different loading capacities are reduced; (2) the mixer truck 200, which is a platform designed by providing the front support base 20, the rear support base 30, the feeding and discharging device 40, and the chassis assembly 10, which are flexible (flexibly connected), enables mixing drums 220 having different loading capacities to be mounted on the same loading platform 100. The universal rate of parts among the stirring trucks 200 with different models is high, the interchangeability is good, and the development period, the manufacturing cost and the maintenance cost are effectively reduced.
