The existing concrete conveying tank is hung under a trolley with four wheels, and the four wheels of the trolley are all arranged on a track which is away from the ground by a preset distance. The trolley moves along the rail, so that the tank body is transferred and transported. Specifically, the four wheels are arranged on the trolley through the rotating shaft, so that the wheels can only rotate but cannot steer.

However, in some cases, the track has a curve, and when the four-wheeled vehicle passes through the curve, the vehicle can pass through the curve strongly because of the different rotation speeds of the inner and outer wheels (as understood by the working principle of the differential mechanism of the vehicle), which causes the conditions of unsmooth turning, delayed turning, and even stuck turning stop.

Further, in order to ensure that the concrete cannot be solidified in the tank body in the transportation process, the tank body is required to rotate around the axis of the tank body, so that the real-time stirring and mixing are simulated, and the concrete is prevented from being solidified.

To solve the above problems, a material conveying apparatus and a conveying system are provided in the following embodiments.

In the present embodiment of the present invention, the walking device 200 further comprises a power source 220, and the power source 220 is at least in transmission connection with one walking wheel 210. The power source 220 is used for driving the travelling wheels 210 to rotate, and further driving the material tank device 100 below the travelling device 200 to move along the track 21.

Further, as can be seen from the figure, in the present embodiment, the power source 220 includes two power mechanisms 221 corresponding to the two traveling wheels 210 one to one; the power mechanism 221 is in transmission connection with the traveling wheels 210.

The arrangement mode enables each walking wheel 210 to move and transmit power through the power mechanism 221 corresponding to the walking wheel, namely, each walking wheel 210 can independently move along the track 21, and therefore the moving flexibility of the walking device 200 is further enhanced.

In the present embodiment of the present invention, the rotation axis of the walking wheel 210 has a preset included angle with the plane of the track 21; and the tops of the two road wheels 210 in the traveling device 200 come close to each other.

Therefore, the traveling wheels 210 can stably support the material tank device 100 on the rails 21, and the stability of the material tank device 100 when the traveling device 200 moves is guaranteed.

As can be seen from the figures, in the present embodiment of the present invention, the material conveying apparatus 10 further includes a guiding device 240; the guiding device 240 is movably disposed on the walking device 200, and the guiding device 240 is used for movably abutting against the side wall 23b of the rail 21.

It is understood that, in other embodiments of the present invention, the guiding device 240 may have other structures as long as the guiding device 240 can limit the guiding of the walking device 200.

As can be seen, the rail 22 has a notch with an inner side surface recessed inwards, the road wheel 210 is embedded in the notch, and the guide 240 is movably supported against the side wall 23b of the notch.

Optionally, in this embodiment, the rail 22 is a channel steel.

Further, the slot of the rail 22 has a side wall 23b, and upper and

Both ends of the link frame 120 are rotatably connected to the two traveling devices 200, respectively, in the extending direction of the rail 21.

When in use, the two walking devices 200 are rotatably connected with the material tank device 100 through the rotating hinge points. The rotary hinge point can rotate in a plane, so that the rotary hinge point has self-steering capability. The trapezoidal traveling wheels 210 are suitable for the channel steel rail 21, and the acting force on the rail 21 in turning is small.

The road wheels 210 react the force of the guide 240 through the track 21 to make the road wheels 210 adapt to the track 21 to turn, driving the whole device smoothly through the curve.

The power source 220 drives the traveling wheels 210 through the transmission shaft 230, so that the equipment has traveling power, and the acting force of the rail 21 on the guide device 240 during traveling enables the traveling device 200 to self-adapt to the turning of the rail 21, so that the whole equipment is driven to smoothly pass through a curve.
