AI Technical Summary
In the process of conveying goods by belt conveyors, existing grab unloaders have problems such as belt misalignment and material spillage caused by changes in the position of the tensioning roller's throwing point. Traditional cleaning devices cannot adapt to changes in the roller's position, resulting in serious material spillage.
The system employs a movable tensioning roller combined with a multi-stage cleaner. Through the adjustable guide plate and the multi-stage cleaner, the position of the material throwing point can be adaptively adjusted to ensure that there is no material spillage when the conveyor belt is tensioned.
It achieves accurate centering of the material throwing point, prevents downstream conveyor belt from running off-center and wearing out, ensures no spillage of return material, improves the stability and environmental performance of the conveying system, and reduces maintenance costs and energy consumption.

Abstract
Claims
1. A material guiding adjustable thrower with mobile multi-stage cleaning, characterized in that, include: Movable tensioning roller, tensioning device, adjustable guide plate, mobile primary sweeper, mobile secondary sweeper, and tertiary self-cleaner; The movable tensioning roller is installed in the frame guide rail and can move back and forth along the guide rail under the action of the tensioning device. Its cylindrical part is arranged inside the discharge mask body. The tensioning device is arranged in the frame guide rail and includes a lug plate, a screw, a tensioning cylinder and a locking nut. The lug plate is connected to the tensioning roller by a hinge. One end of the screw is screwed into the lug plate and the other end passes through the tensioning cylinder and is fixed by the locking nut. The adjustable guide plate is arranged inside the discharge mask body, with its upper end suspended in the positioning ring by a hinge shaft and its lower part equipped with an adjustment handle. The mobile primary sweeper is fixed to the bracket by bolt assembly, the bracket is fixed to the base plate by bolts, and the base plate is fixed to the movable tension roller by bolts. The mobile secondary sweeper is installed in the same way as the mobile primary sweeper, and is arranged behind the primary sweeper; The three-stage self-cleaning device is installed on the frame and automatically rotates to clean the material through friction with the conveyor belt.
2. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, The tensioning device is provided in two sets, which are respectively arranged on both sides of the tensioning roller.
3. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, The adjustable guide plate rotates around the hinge axis by moving the adjustment handle back and forth. At the same time, the positioning rings have different positions, and the upper hinge axis of the adjustable guide plate can be placed in different positioning rings to achieve multi-point and multi-level adjustment of the guide.
4. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, Both the mobile primary sweeper and the mobile secondary sweeper are fixedly mounted on the movable tension roller by bolt assemblies and brackets to ensure that the sweeping device is always in contact with the conveyor belt.
5. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, The three-stage self-cleaning device rotates automatically by friction with the conveyor belt, and the swept-off material is guided into the discharge port through the chute.
6. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, The bracket is divided into two parts, left and right, which are respectively arranged on the outside of the material dispensing mask.
7. The adjustable throw material guide with mobile multi-stage cleaning of claim 1, wherein, The movable tensioning roller can achieve the material throwing function while ensuring the tension of the conveyor belt. The throwing point can move with the tensioning roller, and the centering performance of the dropping point can be ensured by adjusting the position of the guide plate.
8. The adjustable throw material flighting device with mobile multi-stage cleaning of claim 1, wherein, The mobile primary sweeper, mobile secondary sweeper, and tertiary self-cleaner can move with the roller. The tertiary self-cleaner sweeps off and collects the material adhering to the return section.
