Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a low-power automatic feeding device. Background Technology

[0002] Belt conveyors are suitable for industries such as food, beverage, pharmaceuticals, electronics, tobacco, and chemicals. They are widely used for various material receiving and conveying applications. The blast furnace charging method should be selected based on meeting the overall layout requirements and charging capacity. For blast furnaces ranging from 750m³ to 1500m³, both car charging and belt conveyor methods can meet the charging capacity requirements. In such cases, if there are no advantages in the overall layout or process arrangement, such as no advantage in terrain elevation differences or short material transport routes, then car charging is preferable.

[0003] In existing belt conveyors, the friction between the material and the belt needs to be considered when feeding at an angle. When the angle of inclination is too large, a double-layer conveyor is required. Traditional double-layer conveyors use dual motors for driving, which results in high power consumption and high cost.

[0004] Therefore, it is of great significance to provide a low-power automatic feeding device to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a low-power automatic feeding device to solve the problems of high power consumption and high cost of traditional double-layer feeding machines that use dual motors for driving.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The output end of the motor is connected to a lower drive gear, and a lower transmission gear is installed at the end of the lower drive roller. The lower transmission gear is meshed with the lower drive gear.

[0011] Preferably, a fixing plate is installed at one end of the upper frame, and an upper drive gear is rotatably connected to the top of the fixing plate via a rotating bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The upper and lower conveyor belts in this utility model are driven by a single motor. When in use, the motor is started, and the motor drives the lower transmission gear to rotate through the lower drive gear, thereby driving the lower conveyor belt to rotate through the lower drive roller. At the same time, the upper drive gear is driven to rotate through the transmission shaft, and the upper drive gear drives the upper drive roller to rotate through the upper transmission gear, thereby driving the upper conveyor belt to rotate.
