[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example 1: A device for controlling the amount of iron tailings fed, see Figures 1 to 4 , including a conveyor frame 1 and a hopper 3, the hopper 3 is arranged on the conveyor frame 1, and also includes a conveyor belt 2, a guide plate 4 and a material blocking structure 5;

[0032] The conveyor belt 2 is driven on the transmission roller of the conveyor frame 1; the servo motor arranged on the conveyor frame 1 controls the rotation speed of the transmission roller, thereby regulating the conveying speed of the conveyor belt 2; wherein, two grooves 201 are symmetrically provided on the conveying side of the conveyor belt 2; two guide plates 4 are symmetrically fixed on both sides of the discharge end of the hopper 3; two material blocking structures 5 are respectively arranged at the bottom of the two guide plates 4;

[0033] The material blocking structure 5 includes a mounting plate 501 and a blocking plate 502;

[0034] The mounting plate 501 is fixedly mounted on the outer side of the bottom of the guide plate 4 ; the baffle plate 502 is inserted into the mounting plate 501 ; wherein, the bottom end of the baffle plate 502 is inserted into the groove 201 .

[0035] The utility model provides a guide plate 4, a mounting plate 501 and a baffle plate 502, wherein the guide plate 4 guides the iron tailings material transported on the conveyor belt 2, and the exposed gap is blocked by the insertion of the bottom of the baffle plate 502 and the groove 201, thereby reducing the leakage of the iron tailings. This solves the problem that there is a gap between the bottom discharge point of the hopper 3 on the conveyor and the conveyor belt 2, resulting in the iron tailings falling on the conveyor belt 2 being easily leaked from the gap during transportation.

[0036] Specifically, an arc-shaped protrusion is provided at the bottom of the extended end of the guide plate 4, and the arc-shaped protrusion corresponds to the bend of the conveyor belt 2; when the conveyor belt 2 is unloaded at the bend, the iron tailings material is also guided, and the overall guiding effect is better.

[0037] Furthermore, the bottom end of the baffle 502 does not contact the inner bottom wall of the groove 201 , thereby reducing friction and not affecting the transmission of the conveyor belt 2 .

[0038] Furthermore, gaps are left between the two sides of the bottom of the baffle 502 and the two side walls of the groove 201; a number of balls 504 are arranged on both sides of the bottom of the baffle 502; wherein the balls 504 are connected to the baffle 502 through the retaining frame 503, and the balls 504 are in contact with the side walls of the groove 201.

[0039] The utility model provides a retaining frame 503 and a ball 504, which has the advantage of not affecting the transmission of the conveyor belt 2 through the contact and limitation between the ball 504 on both sides of the bottom of the baffle 502 and the two side walls of the groove 201, so that the conveyor belt 2 remains stable during transmission and the possibility of deviation of the conveyor belt 2 is reduced.

[0040] Working principle: When using the device of the utility model, the servo motor arranged on the conveyor frame 1 controls the rotation speed of the transmission roller and adjusts the conveying speed of the conveyor belt 2; when the conveyor belt 2 is driven, the bottom of the baffle 502 and the groove 201 of the conveyor belt 2 move relative to each other, and the ball 504 contacts the side wall of the groove 201; the iron tailings material is added into the hopper 3, and the iron tailings material is discharged from the bottom discharge end of the hopper 3 and falls on the conveyor belt 2 for transportation. During the transportation process, the guide plate 4 guides the iron tailings material transported on the conveyor belt 2, and the exposed gap is blocked by the insertion of the bottom of the baffle 502 and the groove 201, thereby reducing the leakage of iron tailings.
