After the silo is filled with materials, the device automatically moves to the unloading point according to the production process and control system instructions, and then self-flips and unloads the materials in the silo laterally into the silo or material pit on the side of the track, and then returns empty or in an empty train for the next cycle. The device can be used for the transfer and transportation of dry bulk materials such as coal, ore, earth, sand and gravel. The device can operate independently as a single vehicle or can be operated in a train.

[0034] The wheeled travel device consists of a railcar frame 1, running wheels 2, and a running drive 3. The running wheels 2 are mounted on the bottom of the railcar frame 1. The running drive 3 is mounted on the outside of the running wheels 2 and is fixed to the railcar frame 1. It distributes the load across the four wheels and enables the transport trolley to travel along the track. The railcar frame 1 is constructed of welded steel and features raised offset hinge points at both ends for connection to the rotary silo assembly. The railcar frame 1 also features hinge points at both ends for connection to the marshaling connection device.

[0035] The flip drive device consists of a flip drive 4, a pinion 5, etc. The flip drive 4 is connected and fixed to the rail car frame 1; the pinion 5 is installed at the end of the flip drive 4 and engages with the large gear 7 of the rotary silo device; the flip drive device is used to drive the rotation of the rotary silo device to realize the self-flipping function and unloading function of the silo.

[0036] The rotary silo device consists of a silo 6, a large gear 7, a bolt group 8, a T-pin shaft 9, a self-lubricating bearing 10, a bolt group 11, etc.; the silo 6 is made of welded steel structure, and is provided with raised offset hinge points at both ends for connecting and fixing with the wheeled walking device; the large gear 7 is installed at the raised offset hinge points at both ends of the silo 6, and is connected and fixed with the first bolt group 8; the self-lubricating bearing 10 is installed inside the large gear 7; the T-pin shaft 9 will connect and fix the raised offset hinge point of the rail car frame 1 with the raised offset hinge point of the silo 6, and the second bolt group 11 is used to connect and fix the T-pin shaft 9 with the raised offset hinge point of the rail car frame 1.

[0037] The unloading baffle device consists of a middle guard plate 14, a side end guard plate 15, etc., which is used to protect the material from impacting the wheeled walking device and the turning drive device during overturning unloading; the middle guard plate 14 and the side end guard plate 15 are both Z-shaped, with one side fixed to the rail car frame 1; the middle guard plate 14 is installed in the middle of the unloading side of the rail car, mainly used to protect the material from impacting the rail car frame 1 structure; the side end guard plates 15 are installed at both ends of the unloading side of the rail car, mainly used to protect the material from impacting the running wheels 2, running drive 3, turning drive 4, and pinion 5.

[0039] Working principle:

[0040] The running wheels 2 and the running drive 3 are both mounted on the railcar frame 1. When the running drive 3 is working, it drives the running wheels 2 to rotate, thereby driving the railcar frame 1 and the entire vehicle body forward or backward, realizing the function of autonomous running along the track.

[0044] This device can be used for the transfer and transportation of dry bulk materials such as coal, ore, earth, and sand and gravel. It can operate independently or in trains. The cost of a single unit is approximately 1 million RMB, but depending on the project requirements, a six-train system can be constructed at a cost of approximately 6 million RMB. This will play a significant role in technology protection and monopoly, facilitating our company's development of projects in this field.
