[0002] A closed screw feeder is a mechanical device used to convey powdered, granular, or small bulk materials. It uses rotating spiral blades to move the material along the conveyor housing. This type of conveyor is typically designed as a closed structure to prevent leakage and external contamination during conveying, making it suitable for applications where maintaining material purity is crucial.

[0003] The screw feeder disclosed in publication number CN206255658U includes a silo, a feed screw, and a motor for controlling the feed screw. The silo is a cylindrical barrel, an impeller is installed at the bottom of the silo, and the screw feeder also includes a motor for controlling the impeller. The silo of the screw feeder provided by the utility model has a cylindrical barrel structure, which can prevent the material from adhering to both ends of the silo and bridging in the middle. In addition, the impeller stirring structure of the silo not only has a stirring and mixing effect, but also can control the amount of material entering the screw by the rotational speed.

[0004] However, the screw feeder has the following disadvantages: during the material conveying process, it is difficult to clean the material remaining on the inner wall of the feeder, resulting in a long use time and material accumulation inside the feeder, which affects material conveying. Utility Model Content

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a blockage-proof closed spiral feeder, comprising a feeder, a circular cylinder is provided on the top of the feeder, a round cover is provided on one side of the circular cylinder, a driving device is provided on the front of the round cover, a dragon rod is fixedly installed on the output end of the driving device, a scratch assembly is provided on one side of the dragon rod, disassembly bolts are threadedly connected on both sides of the top surface of the circular cylinder, an inspection plate is threadedly connected on the surface of the disassembly bolt, a semi-arc plate is provided adjacent to the inspection plate, and an alarm body is provided on one side of the top surface of the semi-arc plate.

[0007] Optionally, the scratching assembly includes a cavity rod, one side of the dragon rod surface is fixedly connected to the cavity rod at equal distances, a spring is provided inside the cavity rod, and one end of the spring is fixedly connected to a flexible scraper.

[0008] Optionally, an observation window is provided on one side of the front surface of the circular cylinder, and a transparent plate is embedded on the surface of the observation window.

[0009] Optionally, a sensor rod is provided on the other side of the alarm body, and ventilation grooves are provided on both sides of the driving device.

[0010] Optionally, a screw is threadedly connected to the front surface of the driving device, and a mounting plate is threadedly connected to the surface of the screw.

[0011] Optionally, an inspection slot is provided on the front side of the feeder, and a clamping plate is provided at the edge of the inspection slot.

[0012] The utility model provides an anti-blocking closed screw feeder, which has the following beneficial effects:

[0013] 1. This anti-blocking closed spiral feeder is equipped with a dragon rod, a scraping component and a driving device. When a person uses the feeder to convey materials, the person can turn on the power of the driving device. During the rotation of the dragon rod, the material is continuously conveyed along the circular cylinder to the other side of the circular cylinder. The flexible scraper fits the inside of the circular cylinder. As the dragon rod rotates, the material remaining on the inner wall of the circular cylinder is continuously scraped, thereby facilitating the person to quickly clean the material remaining on the inner wall of the circular cylinder and reducing the accumulation of residual material on the inner wall of the circular cylinder.

[0014] 2. The anti-blocking closed screw feeder is equipped with a circular cylinder, an inspection plate and a disassembly bolt. When the feeder is blocked, the personnel can use the disassembly bolt to remove the inspection plate when they need to clear the material inside the feeder, thereby facilitating the personnel to quickly clear the material inside the circular cylinder.
