Preferably, the second side is an adjacent side of the first side, and the chute is also on this side, that is, the side in the traveling direction. The height of the lower end outlet of the chute is higher than the height of the belt conveyor. In addition, a steering mechanism can also be detachably installed at the lower end of the chute, so that the chute can discharge materials in different directions, enabling the device of the present utility model to return the falling materials to the belt conveyor in different positions. The third side is the opposite side of the first side, that is, the front side in the traveling direction; a cleaning door 9 is provided at the lower part of the box body main body 2, preferably on the first side.

[0022] At the lower part of the third side of the box body main body 2 of the box body, preferably, it further includes a third side extension part. The third side extension part extends outward a certain distance in a direction perpendicular to the third side, and the lower opening 6 is provided at its mouth, so as to reduce the volume of the box body main body 2 and make it more flexible to move.

[0023] The cleaning module is installed at the lower opening 6. The cleaning module is composed of 2 sets of cleaning wheels 11, a cleaning wheel central shaft 12, and a connecting rod 13; the cleaning wheel 11 is composed of 4 cleaning scrapers 23 radially connected to the cleaning wheel central shaft 12 with the cleaning wheel central shaft 12 as the center. A brush 24 is provided at the bottom of the cleaning scraper 23.

[0024] The cleaning wheel central shaft 12 is rotatably installed outside the lower opening 6 through the connecting rod 13. A bearing seat can be installed at the end of the connecting rod 13, and a bearing of the cleaning wheel central shaft 12 is arranged in the bearing seat. The connecting rod can be drivably installed on the box body and provided with a corresponding locking mechanism (such as screw locking) to be able to adjust the lateral position of the cleaning wheel central shaft 12, that is, adjust the lateral position of the cleaning wheel.

[0025] The front and rear transportation module is installed behind the cleaning module and consists of a transportation wheel 14 and a horizontally arranged transportation wheel central shaft 15; the transportation wheel 14 is composed of 4 transportation scrapers 25 radially connected to the transportation wheel central shaft 15 with the transportation wheel central shaft 15 as the center. Preferably, the front and rear transportation module is located in the third side extension box body, and the bearings of the transportation wheel central shaft 15 are installed in the bearing seats located in the third side extension box body.

[0026] The vertical transportation module is installed behind the front and rear transportation module and includes a drive shaft 16, an adjustment shaft 17, a fixed shaft 18, a chain 19, a storage hopper 20, a horizontal slide rail 21, and a vertical slide rail 22. Both ends of the drive shaft 16 are installed on the vertical slide rails 22 provided at the left and right ends of the drive shaft 16 with adjustable height, and the vertical slide rails are fixed to the box body main body 2. The horizontal slide rail is fixed inside the box body; the fixed shaft 18 is installed at the lower part inside the box body main body 2; the two adjustment shafts 17 are connected to the horizontal slide rail 21 with adjustable positions at both left and right ends. Among them, the installation position of the adjustment shaft 17 located at the lower part is basically flush with the installation height of the fixed shaft 18, and the other one is installed in the middle part inside the box body main body 2; sprockets of the chain 19 are respectively installed at both ends of the adjustment shaft 17, the fixed shaft 18, and the drive shaft 16. The drive shaft 16 is connected to the drive module through a chain transmission device, and drives the sprockets at both ends of the drive shaft 16 to rotate. The chains 19 provided at both left and right ends are supported by the sprockets respectively installed at both ends of the adjustment shaft 17, the fixed shaft 18, and the drive shaft 16 and run in a cycle; a plurality of storage hoppers 20 are installed on the chain 19. The upper end of the circulating loop of the chain 19 corresponds to the upper opening 5, and the lower part corresponds to the storage bin 10 located below the vertical transportation module. Tensioning sprockets of the chain 19 can also be provided inside the box body to tension the chain 19 after the position of the adjustment shaft 17 is adjusted and the height of the drive shaft is adjusted. Similarly, a tensioning sprocket is also provided for the chain transmission device between the drive shaft 16 and the drive module.

[0027] A storage bin 10 is provided inside the box body. The storage bin 10 is located between the front and rear transportation module and the vertical transportation module, at the end of the front and rear transportation module to receive the falling materials cleaned and transported, and is transported upward by the vertical transportation module.

[0028] The drive module 7 is fixed to the box body. Preferably, taking advantage of the horizontal extension feature of the third side extension part, the drive module 7 is installed thereon. The drive module 7 can adopt one motor or several motors, which are connected to the cleaning wheel central shaft 12, the transportation wheel central shaft 15, and the drive shaft 16 through a transmission device. The transmission device can be a transmission device composed of gears and transmission shafts, or a belt transmission device or a chain transmission device, or a combined transmission device composed of a transmission device composed of gears and transmission shafts and a belt transmission device or a chain transmission device.

[0029] During specific use, a worker holds the handrail 3 and pushes the device of the present invention forward or stops the device of the present invention at a place with a large amount of fallen materials, so that the cleaning wheel 11 can contact the fallen materials. The cleaning wheel 11 can adjust the fitting degree between the cleaning scraper 23 and the ground by adjusting the inclination angle of the cleaning wheel central shaft 12, and adjust the cleaning range of the cleaning wheel 11 by adjusting the horizontal position of the connecting rod 13; the driving module 7 drives the cleaning wheel 11 to rotate through the transmission device. Under the rotation action of the 2 sets of cleaning wheels 11, the fallen materials enter the inside of the box body 2 through the lower opening 6 and contact the conveying scraper 25 of the conveying wheel 14; the driving module 7 drives the conveying wheel 14 to rotate clockwise vertically through the conveying wheel central shaft 15, and the conveying scraper 25 pushes the fallen materials into the storage bin 10 at the rear; the driving module 7 drives the driving shaft 16 to rotate counterclockwise, and the rotation of the driving shaft 16 drives the chain 19 to move counterclockwise, thereby driving the storage hopper 20 to move; during the movement of the storage hopper 20, when passing through the storage bin 10, it shovels up the fallen materials therein and continues to move upward, reaches the highest point at the driving shaft 16, and then bypasses the driving shaft 16 and starts to move downward. At this time, the fallen materials in the storage bin 10 slide into the chute 8 through the upper opening 5 under the action of gravity, and the fallen materials continue to return to the belt surface of the nearby belt conveyor or the transport trolley under the action of gravity. If the belt surface of the belt conveyor is relatively high, the lifting height of the fallen materials can be increased by horizontally moving the adjusting shaft 17 to the left on the horizontal slide rail 21, moving the driving shaft 16 upward on the vertical slide rail 22, and then raising the position of the chute 8, and vice versa. In addition, if there is too much fallen material in the storage bin 10 and it becomes blocked, it can be manually cleaned by opening the cleaning door 9.

[0030] The above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the application of the present invention shall fall within the scope covered by the present invention.
