Background

The screw feeder has the advantages of stable conveying capacity, quick locking and the like as a traditional conveying device for bulk powder materials. But as volume type conveying equipment, materials are conveyed by crushing through blade friction, the pressure of the upper materials can act inside the screw conveyor, and the blades need to overcome larger resistance when rotating; also, the more viscous and moist material is more difficult to push or break after extrusion.

The screw feeder has insufficient functions due to the reasons as follows: the vane is worn quickly and needs to be replaced regularly; the power of the driving mechanism is generally larger than that of the vibrating feeder with the same specification; the adaptability to materials which are sticky and wet or have large bin pressure is not strong.

To sum up, the prior screw feeder has the following problems: the replacement period of the blade or the lining plate of the screw conveyor is short, so that the overall cost of the equipment is increased; the screw conveyer can only be used for the condition that the bin pressure is low, the material particles are small and are drier, and the market development of products is limited.

Disclosure of Invention

In order to achieve the above purpose, the utility model adopts the following technical scheme: a vibrating screw feeder comprises a feed hopper, a groove body, a screw shaft, screw blades, a driving system, a discharge chute, a vibration isolation spring set, a vibrating motor, a flexible connecting cover and a fixed support; the head of the tank body is connected with a feeding hopper through a flexible connecting cover, the tail of the tank body is connected with a discharging chute through a flexible connecting cover, a rapping motor is installed on the tank body, and the lower part of the tank body is arranged on a fixed support through a vibration isolation spring group; the spiral shaft is provided with a spiral blade, penetrates into the groove body and is not in contact with the groove body, the spiral shaft is connected with the groove body through a flexible connecting cover, the head section and the tail section of the spiral shaft are arranged on the fixed support, and the spiral shaft is connected with the driving system.

In the technical scheme, the inner radius of the groove body is 15-20mm larger than the outer radius of the helical blade.

In the technical scheme, the opening is formed in the plate at the head end and the tail end of the groove body, the spiral shaft is arranged, and the distance between the edge of the opening and the spiral shaft is kept to be more than 15 mm.

In the technical scheme, the flexible connecting cover is made of wear-resistant canvas, and the end part of the flexible connecting cover is fixedly connected with the groove body, the feeding hopper or the discharging chute through the flange.

In the above technical solution, the rapping motor is arranged on the end plate at the upper part of the tank body.

The utility model has the advantages that: 1. the vibration of the rapping motor has a loosening effect on internal materials, so that the abrasion speed of the helical blade is reduced, and the service life of equipment is prolonged; 2. the situation that sticky and wet materials are squeezed inside and blocked is effectively prevented; 3. the motor power required by the driving system is reduced, and the energy consumption is saved.
