Feeding device capable of adjusting discharging amount

Abstract

The invention discloses a feeding device capable of adjusting the discharging amount. The feeding device capable of adjusting the discharging amount comprises a feeding hopper, a screw conveying mechanism, a material bin and a control unit, wherein the material bin comprises a cylinder and a cone cylinder, the big end of the cone cylinder is upwards and is in communication with the cylinder, the large end of the conical cylinder is equal to the circular area of the section of the cylinder, a movable plate is hinged to the inner wall of the cylinder, the inner wall of the cylinder is fixedly connected with an air cylinder above the movable plate, the air cylinder is electrically connected with the control unit, a telescopic rod of the air cylinder is connected with one end, away from the hinged position, of the movable plate, the telescopic rod of the air cylinder acts, the movable plate is controlled to rotate so as to adjust the contact area of the movable plate and the falling material, a discharge hole is formed in the bottom of the material bin, one end of the discharge port is hinged to a bin door, one end, away from the hinged position, of the bin door is connected with an elastic piece, and the other end of the elastic piece is connected with the inner wall of the cone cylinder. The feeding device have the advantages that the material discharging amount can be adjusted,and the requirements of users can be met.

Description

technical field [0001] The invention relates to the technical field of mechanical conveying, in particular to a feeding device with adjustable feeding amount. Background technique [0002] After the production of powder and granular materials is completed, it is often necessary to transport the particles and powder materials to a certain height. Most of the existing feeding devices are screw feeding devices, which lift the materials to the top through the screw spindle, and then fall into the In the silo, it falls from the outlet of the silo, and the cycle continues, so as to achieve the purpose of conveying materials. However, this feeding device cannot adjust the amount of material to be discharged. After the material lifted by the screw spindle reaches the silo, the material will continue to fall through the discharge port of the silo, and the amount of material to be discharged cannot be adjusted. After the material is about to reach the required amount, it is necessary...

Problems solved by technology

However, this feeding device cannot adjust the amount of material to be discharged. After the material lifted up by the screw spindle reaches the silo, the material will continue to fall through the discharge port of the silo, and the amount of material to be discharged cannot be adjusted. After the material is about to reach the required amount, it is necessary to gradually reduce the amount of falling material to control the accuracy of the amount of packed material, but the existing feeding device cannot meet the required requirements
