[0007] A conveying device for feeding a ring hopper feeder comprises a feed hopper, a cylinder inclined upward from left to right is provided below the feed hopper, a rotating cavity is provided in the cylinder, the lower end of the feed hopper is communicated with the rotating cavity of the cylinder, a rotating shaft is rotatably provided in the cylinder, a first stirring blade arranged in a spiral shape is provided on the rotating shaft, a support plate is provided for fixing the cylinder, a support plate is provided on the support plate, a driving device is provided on the support plate, the driving device is used to drive the rotating shaft to rotate, and a discharge barrel communicated with the rotating cavity is provided at the lower right end of the cylinder.

[0008] A further technical solution is that sealing disks are provided on both sides of the cylinder, and connecting rings are fixedly sleeved on both side openings of the cylinder, and the sealing disks are connected to the connecting rings by bolts.

[0009] A further technical solution is that a second stirring blade arranged in a spiral shape is provided at one end of the sealing disk of the rotating shaft close to the left side of the cylinder, and the spiral direction of the second stirring blade is opposite to that of the first stirring blade; an opening connected to the rotating cavity is provided on the sealing disk of the rotating shaft close to the left side of the sleeve, and a collecting bag is provided at the opening.

[0010] A further technical solution is that the feed hopper is arranged on a support frame, and an outlet of the feed hopper is arranged toward the first stirring blade.

[0011] A further technical solution is that the driving device includes a motor arranged on the support plate, a first pulley is provided at the output end of the motor, the right end of the rotating shaft rotates through the sealing disk and is connected to a second pulley, and the first pulley and the second pulley are connected by a belt drive.

[0012] A further technical solution is that a conduit in an S-shape is provided at the lower end of the discharge cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The material to be fed into the ring hopper feeder is first passed through the feed hopper into the cylinder body, and the driving device drives the rotating shaft to rotate, so that the material is crushed by the first stirring blade on the rotating shaft, and the crushed material is estimated by the first stirring blade to be discharged through the discharge barrel. During the material transportation process, the material is crushed by the first stirring blade, and at the same time, the first stirring blade rotates at a uniform speed so that an equal amount of material is discharged into the ring hopper feeder through the discharge barrel, thereby reducing the uneven material distribution of the ring hopper feeder, and allowing the crushed material to quickly pass through the channel to reach the silo, while avoiding the problem of large-volume materials contacting the scraper, which can easily cause damage to the scraper.
