A temporary storage box is arranged directly above the feeding area at the bottom of the conveying frame. A filter screen is installed inside the temporary storage box, and a feeding hopper is connected and arranged at the bottom of the temporary storage box;
[0007] A pair of support legs are fixed on both sides of the temporary storage box. A sliding column is arranged at the bottom of the support leg, and a support plate is fixed at the bottom of the sliding column. The support plate is fixed on the floor by a plurality of ground anchors;
[0008] The top of the sliding column extends into the inside of the support leg, and a return spring is sleeved on the sliding column. One end of the return spring is fixed on the support plate, and the other end of the return spring is fixed on the support leg.
[0009] In a preferred embodiment, a discharge groove is formed on one side of the temporary storage box, and the discharge groove is directly above the bottom of the filter screen.
[0010] In a preferred embodiment, a T-shaped seat is fixed between a pair of the support legs. Two limit seats are fixedly spaced on the floor. A rotating shaft is movably arranged between the two limit seats through a bearing, and a cam is installed on the rotating shaft. The cam is in contact with the bottom of the T-shaped seat.
[0011] In a preferred embodiment, a motor is provided on one side of the limit seat, and the output end of the motor is connected to the rotating shaft through a coupling.
[0012] In a preferred embodiment, a bracket is fixed below the conveying frame, and a scraper is fixed on the bracket. The scraper is in contact with the surface of the conveyor belt on the conveying frame.
[0013] In a preferred embodiment, a collection box is placed on the floor, and the collection box is located directly below the scraper.
[0014] Advantages of the present utility model:
[0015] 1. When this belt conveyor is in use, the staff can first add the dry sand to be conveyed into the temporary storage box.
